Safety Rules  
Recreational Vehicle Generator  
SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe  
operation be copied and posted near the unit’s installation site. Safety should be stressed to  
all operators and potential operators of this equipment.  
WARNING:  
contains chemicals known to the state  
of California to cause cancer, birth  
defects or other reproductive harm.  
GENERAL HAZARDS  
The engine exhaust from this product  
For safety reasons, the manufacturer recommends  
that the installation, initial start-up and main-  
tenance of this equipment is carried out by an  
Authorized Service Dealer.  
• The generator engine releases DEADLY carbon  
monoxide gas through its exhaust system. This  
dangerous gas, if breathed in sufficient concentra-  
tions, can cause unconsciousness or even death.  
Never operate the generator set with the vehicle  
inside any garage or other enclosed area. DO NOT  
OPERATE THE GENERATOR IF THE EXHAUST  
SYSTEM IS LEAKING OR HAS BEEN DAMAGED.  
SYMPTOMS OF CARBON MONOXIDE POISONING  
ARE (a) inability to think coherently, (b) nausea,  
(c) vomiting, (d) twitching muscles, (e) throbbing  
temples, (f) dizziness, (g) headaches, (h) weak-  
ness, and (i) sleepiness. IF EXPERIENCING ANY  
OF THESE SYMPTOMS, MOVE INTO FRESH AIR  
IMMEDIATELY. IF SYMPTOMS PERSIST, GET  
MEDICAL HELP. Shut down the generator and  
do not operate it until it has been inspected and  
repaired.  
WARNING:  
This product contains or emits chemicals  
known to the state of California to cause  
cancer, birth defects or other reproductive harm.  
Study these SAFETY RULES carefully before install-  
ing, operating or servicing this equipment. Become  
familiar with this Owner’s Manual and with the  
unit. The generator can operate safely, efficiently and  
reliably only if it is properly installed, operated and  
maintained. Many accidents are caused by failing to  
follow simple and fundamental rules or precautions.  
The manufacturer cannot anticipate every possible  
circumstance that might involve a hazard. The warn-  
ings in this manual, and on tags and decals affixed  
to the unit are, therefore, not all-inclusive. If using  
a procedure, work method or operating technique  
the manufacturer does not specifically recommend,  
ensure that it is safe for others. Also make sure the  
procedure, work method or operating technique uti-  
lized does not render the generator unsafe.  
• Never sleep in the vehicle while the genset is run-  
ning unless the vehicle has a working carbon  
monoxide detector. The exhaust system must be  
installed in accordance with the genset installation  
manual. Make sure there is ample fresh air when  
operating the genset in a confined area.  
DANGER  
• The engine exhaust fumes contain carbon monox-  
ide, which can be DEADLY. This dangerous gas, if  
breathed in sufficient concentrations, can cause  
unconsciousness or even death. This exhaust  
system must be installed properly, in strict com-  
pliance with applicable codes and standards.  
Following installation, do nothing that might ren-  
der the system unsafe or in noncompliance with  
such codes and standards. The generator com-  
partment must be completely vapor sealed from  
the vehicle interior. There must be no possibility of  
exhaust fumes entering the vehicle interior. Never  
operate this equipment with a leaking or defective  
exhaust system.  
Despite the safe design of this generator, operat-  
ing this equipment imprudently, neglecting its  
maintenance or being careless can cause possible  
injury or death. Permit only responsible and capa-  
ble persons to operate or maintain this equip-  
ment.  
Potentially lethal voltages are generated by  
these machines. Ensure all steps are taken to  
render the machine safe before attempting to  
work on the generator.  
Parts of the generator are rotating and/or hot  
during operation. Exercise care near running  
generators.  
• Keep hands, feet, clothing, etc., away from drive  
belts, fans, and other moving or hot parts. Never  
remove any drive belt or fan guard while the unit  
is operating.

Safety Rules  
Recreational Vehicle Generator  
• Adequate, unobstructed flow of cooling and ven-  
tilating air is critical to correct generator opera-  
tion and is required to expel toxic fumes and fuel  
vapors from the generator compartment. Without  
sufficient cooling airflow, the engine/generator  
quickly overheats, which causes serious damage  
to the generator. Do not alter the installation or  
permit even partial blockage of ventilation provi-  
sions, as this can seriously affect safe operation of  
the generator.  
• In case of accident caused by electric shock, imme-  
diately shut down the source of electrical power.  
If this is not possible, attempt to free the victim  
from the live conductor. AVOID DIRECT CONTACT  
WITH THE VICTIM. Use a nonconducting imple-  
ment, such as a rope or board, to free the victim  
from the live conductor. If the victim is uncon-  
scious, apply first aid and get immediate medical  
help.  
• When working on this equipment, remain alert  
at all times. Never work on the equipment when  
physically or mentally fatigued.  
• Inspect the generator regularly, and contact the  
nearest Authorized Service Dealer immediately for  
parts needing repair or replacement.  
• Before performing any maintenance on the gen-  
erator, disconnect its battery cables to prevent  
accidental start up. Disconnect the cable from the  
battery post indicated by a NEGATIVE, NEG or (–)  
first. Reconnect that cable last.  
• Never use the generator or any of its parts as a  
step. Stepping on the unit can stress and break  
parts, and may result in dangerous operating con-  
ditions from leaking exhaust gases, fuel leakage,  
oil leakage, etc.  
• Never wear jewelry when working on this equip-  
ment. Jewelry can conduct electricity resulting in  
electric shock, or may get caught in moving com-  
ponents causing injury.  
FIRE HAZARDS  
For fire safety, the generator must be installed  
and maintained properly. Installation always must  
comply with applicable codes, standards, laws  
and regulations. Adhere strictly to local, state and  
national electrical and building codes. Comply  
with regulations the Occupational Safety and  
Health Administration (OSHA) has established.  
Also, ensure that the generator is installed in  
accordance with the manufacturer’s instructions  
and recommendations. Following proper installa-  
tion, do nothing that might alter a safe installation  
and render the unit in noncompliance with the  
aforementioned codes, standards, laws and regula-  
tions.  
• Keep a fire extinguisher in the vehicle at all times.  
Extinguishers rated ABC” by the National Fire  
Protection Association are appropriate for use on  
the recreational vehicle generator electrical sys-  
tem. Keep the extinguisher properly charged and  
be familiar with its use. If there are any questions  
pertaining to fire extinguishers, consult the local fire  
department.  
ELECTRICAL HAZARDS  
• The generator covered by this manual produces  
dangerous electrical voltages and can cause fatal  
electrical shock. Avoid contact with bare wires, ter-  
minals, connections, etc., while the unit is running.  
Ensure all appropriate covers, guards and barriers  
are in place before operating the generator. If work  
must be done around an operating unit, stand on  
an insulated, dry surface to reduce shock hazard.  
• Do not handle any kind of electrical device while  
standing in water, while barefoot, or while hands or  
feet are wet. DANGEROUS ELECTRICAL SHOCK  
MAY RESULT.  
EXPLOSION HAZARDS  
• During installation onto the vehicle, have the  
generator properly grounded (bonded) either by  
solid mounting to the vehicle frame or chassis,  
or by means of an approved bonding conductor.  
DO NOT disconnect the bonding conductor, if so  
equipped. DO NOT reconnect the bonding conduc-  
tor to any generator part that might be removed or  
disassembled during routine maintenance. If the  
grounding conductor must be replaced, use only a  
flexible conductor that is of No. 8 American Wire  
Gauge (AWG) copper wire minimum.  
• Do not smoke around the generator. Wipe up any  
fuel or oil spills immediately. Ensure that no com-  
bustible materials are left in the generator com-  
partment, or on or near the generator, as FIRE or  
EXPLOSION may result. Keep the area surround-  
ing the generator clean and free from debris.  
• Gasoline is extremely FLAMMABLE and its vapors  
are EXPLOSIVE. Do not permit smoking, open  
flame, sparks or any source of heat in the vicinity  
while handling gasoline. Comply with all laws gov-  
erning the storage and handling of gasoline.

Section 1 – General Information  
Recreational Vehicle Generator  
1.2 GENERATOR APPLICABILITY  
1.4 GENERATOR AC  
These generators have been designed and manufac-  
tured for supplying electrical power for recreational  
vehicles. Do not modify the generator or use it for  
any application other than for what it was designed.  
If there are any questions pertaining to its applica-  
tion, write or call the factory. Do not use the unit until  
advised by a competent authority.  
CONNECTION SYSTEM  
This generator set is equipped with dual stator AC  
power windings. These two-stator windings sup-  
ply electrical power to customer electrical loads by  
means of a two-wire connection system. Note, how-  
ever, that the neutral is bonded to the frame of the  
engine-generator.  
DANGER  
The generator may have been installed so that it pow-  
ers 120-volt AC loads (Figure 1.1).  
For fire safety, the generator must have been  
properly installed in compliance with ANSI  
Figure 1.1 – Connections for 120 Volts Only  
119.2-1975/NFPA 501C-1974, “Standard for  
Recreational Vehicles, Part III – Installation of  
Electrical Systems.” The generator also must  
have been installed in strict compliance with the  
manufacturer’s detailed installation instructions.  
After installation, do nothing that might render  
the unit in noncompliance with such codes, stan-  
dards and instructions.  
Use this generator to supply electrical power for  
operating 120-volt, single-phase, 60 Hertz, AC elec-  
trical loads. These loads can require up to 3,400  
watts (3.4 kW) of power, but cannot exceed 28.3 AC  
amperes of current at 120 volts.  
1.5 SPECIFICATIONS  
Do not overload the generator. Some installa-  
tions may require that electrical loads be alter-  
1.5.1 FUEL REQUIREMENTS  
nated to avoid overloading. Applying exces-  
sively high electrical loads may damage the  
generator and may shorten its life. Add up the  
rated watts of all electrical lighting, appliance,  
tool and motor loads the generator will power  
at one time. This total should not be greater  
than the wattage capacity of the generator. If an  
electrical device nameplate gives only volts and  
amps, multiply volts times amps to obtain watts  
(volts x amps = watts). Some electric motors  
require more watts of power (or amps of cur-  
rent) for starting than for continuous operation.  
These generators are equipped with a liquefied petro-  
leum (LP) gas fuel system. LP gas is usually aupplied  
as a liquid in pressure tanks.  
These generators require a “vapor withdrawal” type  
fuel system. This type of gaseous fuel system uses the  
vapors forming above the liquid fuel in the storage  
tank. Air temperature around the storage tank must  
be high enough to sustain adequate fuel vaporization.  
In colder climates, use of an independent heat source  
may be needed to be sure the fuel sufficiently vapor-  
izes in the storage tank.  
LP gas may consist of propane, butane, or a mixture  
of the two gases. Propane vaporizes at tempertures as  
low as -20°F (-29°C), but butane returns to its liquid  
state when the temperature drops below about 32°F  
(0°C). For that reason, a higher ratio of propane is  
desired in the gas mixure when temperatures drop  
below freezing.  
1.3 SAFETY  
Before attempting to use the generator set, care-  
fully read the “Safety Rules” section of this manual.  
Comply strictly with these rules to prevent accidents  
and damage to equipment and/or property. We sug-  
gest copying and posting the “Safety Rules” in poten-  
tial hazard areas of the vehicle. Stress safety to all  
operators and potential operators of this equipment.

2.1.4 MAIN BREAKER  
2.3.4 COOLING AND VENTILATING AIR  
Air inlet and outlet openings in the generator com-  
partment must be open and unobstructed for con-  
tinued proper operation. Without sufficient cooling  
and ventilating airflow, the engine/generator quickly  
overheats, which causes it to shut down and may  
damage the generator.  
The main breaker protects the generator’s AC out-  
put circuit against overload and provides a method  
of turning OFF the generator’s 120-volt AC output  
to the vehicle circuits. This generator has a 30-amp  
breaker.  
2.2 OPTIONAL REMOTE  
2.3.5 ENGINE EXHAUST GAS  
START/STOP PANEL  
Before starting the generator engine, be sure there is  
no way for exhaust gases to enter the vehicle interior  
and endanger people or animals. Close windows,  
doors and other openings in the vehicle that, if open,  
might permit exhaust gases to enter the vehicle.  
A remote mounted Start/Stop Panel is available that  
allows starting and stopping the generator engine  
conveniently from inside the vehicle.  
Order part number 0F0429 or 0F0430, a remote  
panel that includes a Start/Stop switch, a generator  
run lamp, a fuel prime switch, and an hourmeter.  
The hourmeter provides a continuous indication of  
engine/generator operating time. Use the hourmeter  
for checking off periodic maintenance requirements  
on the unit.  
DANGER  
The generator engine releases DEADLY carbon  
monoxide gas through its exhaust system. This  
dangerous gas, if breathed in sufficient con-  
centrations, can cause unconsciousness or even  
death. Never operate the generator set with  
the vehicle inside any garage or other enclosed  
area. DO NOT OPERATE THE GENERATOR IF THE  
EXHAUST SYSTEM IS LEAKING OR HAS BEEN  
DAMAGED. SYMPTOMS OF CARBON MONOXIDE  
POISONING ARE (a) inability to think coher-  
ently, (b) nausea, (c) vomiting, (d) twitching  
muscles, (e) throbbing temples, (f) dizziness,  
(g) headaches, (h) weakness, and (i) sleepiness.  
IF EXPERIENCING ANY OF THESE SYMPTOMS,  
MOVE INTO FRESH AIR IMMEDIATELY. IF

To start the generator from either the generator con-  
trol panel or from the optional remote panel, proceed  
as follows:  
2.6.1 LETTING THE ENGINE STABILIZE  
The generator supplies correct rated voltage only at  
the proper governed speed. Some electrical appli-  
ances may be extremely sensitive to voltage. Incorrect  
voltages can damage such appliances.  
1. Turn OFF electrical loads using the means pro-  
vided in the vehicle (such as a main line circuit  
breaker or transfer switch).  
If electrical loads are applied at reduced operating  
speeds, such loads imposed on the engine when suf-  
ficient power is not available may shorten engine life.  
Never turn ON electrical loads until after the genera-  
tor engine has started and stabilized at no-load.  
NOTE:  
If starting from the generator control panel, turn  
OFF loads by setting the generator’s main circuit  
breaker to the OFF (or open) position. If starting  
from a remote panel, turn OFF loads using the  
means provided in the vehicle (such as a main  
circuit breaker). Electrical load circuits will be  
turned ON after the generator has started, stabi-  
lized and warmed up.  
2.7 DO NOT OVERLOAD THE  
GENERATOR  
Read the rated wattage/amperage capacity of the  
generator on the generator data label (see "Generator  
Identification").  
2. If the engine has not been started in more than  
two weeks, press the Fuel Pump Primer switch  
and hold it for about 10 to 15 seconds to prime  
the fuel system. However, if the engine is warm,  
skip Step 2.  
3. Hold the engine Start/Stop switch in the START  
position to crank the engine. Release the switch  
when the engine starts.  
Applying electrical loads in excess of the unit’s rated  
capacity will cause the engine/generator to automati-  
cally shut down.  
To avoid overloading, add up the wattage of all con-  
nected electrical lighting, appliance, tool and motor  
loads. This total should not be greater than the  
generator’s rated wattage capacity.  
• Most lighting, appliance, tool and motor loads  
indicate their required watts on their nameplate or  
data plate. For light bulbs, simply note the wattage  
rating of the bulb.  
• If a load does not show its rated wattage, multiply  
that load’s rated VOLTS times AMPS to obtain  
WATTS.  
If the engine does not start after it has been  
cranking for 15 seconds, release the Start/Stop  
switch, wait one minute and try again. Holding  
the switch for longer than 15 seconds can dam-  
age the starter motor.  
4. Let the engine run at no-load for a few minutes to  
stabilize and warm up.  
• Induction type motors (such as those that run the  
vehicle’s furnace fan, refrigerator, air conditioner,  
etc.) need about 2-1/2 time more watts of power for  
starting than for running (for a few seconds during  
motor starting). Be sure to allow for this when con-  
necting electrical loads to the generator. First, fig-  
ure the watts needed to start electric motors in the  
system. To that figure, add the running wattages of  
other items that will be operated by the generator.  
• Do not apply heavy electrical loads for the first two  
or three hours of operation.  
5. Turn ON electrical loads using the means pro-  
vided (such as a main circuit breaker or transfer  
switch).  
2.5 STOPPING THE GENERATOR  
1. Turn OFF all electrical loads using the means  
provided (such as a main circuit breaker or  
transfer switch).  
2. Let generator run at no-load for a few minutes, to  
stabilize internal engine generator temperatures.  
3. Place the Start/Stop switch in its STOP position.  
2.8 PROTECTION SYSTEMS  
2.6 APPLYING LOADS TO GENERATOR  
When applying electrical loads to the generator,  
observe these guidelines:  
2.8.1 LOW OIL PRESSURE SWITCH  
This switch (Figure 2.2) has normally closed (N.C.)  
contacts that are held open by engine oil pressure dur-  
ing cranking and operating. Should oil pressure drop  
below a preset level, switch contacts close, and the  
engine automatically shuts down. The unit should not  
be restarted until oil is added.  
• Before applying electrical loads, let the generator  
stabilize and warm up for a minute or two.  
• DO NOT overload the generator.

Section 2 – Operation  
Recreational Vehicle Generator  
2.8.2 HIGH TEMPERATURE SWITCH  
2.8.4 OVERVOLTAGE PROTECTION  
This switch (Figure 2.2), which has normally open  
(N.O.) contacts, is mounted near the oil filter. The  
contacts close if the temperature should exceed  
approximately 284º F (140º C), initiating an engine  
shutdown.  
A solid-state voltage regulator (Figure 2.4) controls  
the generator’s AC output voltage. This regulator sup-  
plies an excitation current to the rotor. By regulating  
the rotor’s excitation current, the strength of its mag-  
netic field is regulated and, in turn, the voltage deliv-  
ered to connected electrical loads is controlled. When  
the AC frequency is 60 Hertz, voltage is regulated at  
120 volts (voltage-to-frequency ratio is 2-to-1).  
Figure 2.2 – Low Oil Pressure and  
High Temperature Switches  
High Temperature Switch  
Figure 2.4 – Solid State Voltage Regulator  
Low Oil Pressure  
Switch  
The voltage regulator also incorporates a “voltage  
surge protection circuit.” This circuit prevents trou-  
blesome surges in the generator AC output voltage.  
Voltage surge is a common cause of damage to elec-  
tronic equipment.  
2.8.3 FIELD BOOST  
The Controller Circuit Board houses a field boost  
diode and resistor that are not part of the automatic  
choke circuit. These two components are part of  
a “field boost” circuit (Figure 2.3). During engine  
cranking only, a positive DC (battery) voltage is  
delivered through the diode, resistor, brushes and  
slip rings, to the generator rotor. Application of this  
voltage to the rotor “flashes the field” whenever it is  
started. Flashing of the field each time the generator  
starts makes sure that a sufficiently strong magnetic  
field is available to produce “pickup” voltage in the  
stator windings.  
2.9 ADDITIONAL INFORMATION  
2.9.1 25-HOUR BREAK-IN PERIOD  
The first 25 hours of operation is the break-in period  
for the generator. Properly breaking in the genera-  
tor is essential to minimize fuel consumption and  
provide maximum engine performance. During this  
25-hour break-in period, follow this procedure:  
• Run the unit at varying electrical loads to help seat  
the engine piston rings properly.  
Figure 2.3 – Field Boost Circuit  
• Check the engine oil level frequently. Add oil if  
needed. It is normal for the generator engine to  
consume more oil than is normal until the piston  
rings have properly seated.  
For the 75-hour operation following the break-in  
period, avoid light electrical loads. Load the gen-  
erator at 50 percent (or more) of its rated watt-  
age capacity. Repeated light loads during these 75  
hours can cause improper seating of engine piston  
rings, resulting in blowby and high oil consump-  
tion.  
• After operating the unit for 25 hours, complete the  
tasks recommended under "25-Hour Check-up".

2.9.2 25-HOUR CHECK-UP  
2.9.5 EFFECTS OF MOISTURE AND DIRT  
After the 25-hour break-in period, contact an  
Authorized Service Dealer for the following main-  
tenance. The vehicle owner is responsible for any  
charges:  
Keep the generator set as clean and dry as possible.  
Protect the unit against excessive dust, dirt, cor-  
rosive vapors, road splash, etc. Permitting dirt and  
moisture to accumulate on generator windings will  
have an adverse effect on the insulation resistance of  
those windings.  
• Change the engine crankcase oil and oil filter.  
• Check the oil level.  
When moisture is allowed to remain in contact with  
windings, some of the moisture will be retained in  
voids and cracks in the insulation. This causes a  
reduced insulation resistance and will eventually  
cause problems. Dirt will make the problem worse,  
since dirt tends to hold moisture in contact with  
windings. Salt (as from sea air) also will worsen the  
problem since it tends to absorb moisture from the  
air. Salt and moisture, when combined, form a good  
electrical conductor.  
• Inspect the cooling and ventilation openings.  
• Check the engine carburetor adjustments.  
• Check the engine ignition system.  
• Inspect the entire electrical system.  
• Inspect the engine exhaust system.  
2.9.3 ATTENTION REQUIRED  
AFTER SUBMERSION  
If the recreational vehicle generator has been sub-  
merged in water, it MUST NOT be started and oper-  
ated. Following any submersion in water, have an  
Authorized Service Dealer thoroughly clean and dry  
the generator.  
3.1 CHECKING THE ENGINE OIL  
LEVEL  
For oil capacities and requirements, see “Engine Oil  
Requirements” section. Check the engine crankcase  
oil level at least every eight hours of operation, or  
before using it. To check the engine oil level, proceed  
as follows (see Figure 3.1):  
2.9.4 OPERATION IN HIGH GRASS  
OR BRUSH  
Never operate the generator while the vehicle is  
parked over high grass, weeds, brush, leaves or any  
other combustible substance. Such materials can  
ignite and burn from the heat of the exhaust system.  
The generator exhaust system becomes extremely  
hot during operation and remains hot for a long time  
after it has shut down.  
1. Be sure the generator is as level as possible.  
2. Remove the dipstick and wipe it dry with a clean,  
lint-free cloth.  
3. Install and tighten the dipstick cap; then, remove  
it again. The oil level should be at the dipstick  
Full” mark.

3.3 MAINTAINING THE ENGINE  
AIR CLEANER  
3.3.1 CLEANING THE FOAM PRECLEANER  
3.2 CHANGING THE ENGINE OIL  
Clean and re-oil the foam precleaner every three  
months or every 25 hours of operation, whichever  
occurs first. Service the foam precleaner more fre-  
quently if operating the generator in extremely dusty  
or dirty conditions. Use the following procedure  
(Figure 3.2):  
AND/OR OIL FILTER  
• Change the engine oil after the first 25 hours of  
operation (after the 25-hour break-in period sec-  
tion). Thereafter, change the oil every 100 oper-  
ating hours. Change the oil more frequently if  
operating consistently under heavy load or at high  
ambient temperatures.  
1. Turn the two screws counterclockwise to loosen.  
2. Remove the cover, foam precleaner and paper filter.  
3. Remove the foam precleaner from the cover.  
4. Wash the foam precleaner in liquid detergent and  
water.  
• Change the engine oil filter after the first 25 hours  
of operation, and every 100 operating hours there-  
after.  
To change the oil and/or oil filter, proceed as follows  
5. Wrap the foam precleaner in a clean cloth and  
(see Figure 3.1):  
gently squeeze it dry.  
1. Run the engine until it is thoroughly warmed up  
(at least five minutes) then shut OFF the engine.  
2. Immediately after the engine shuts OFF, pull the  
oil drain cover free of the base. Remove the plug  
from the tube with a 5/16” allen wrench and drain  
the oil into a suitable container. Loosening the oil  
fill cap will allow the crankcase to drain faster.  
3. After the oil has drained, replace the plug onto  
the end of the oil drain tube. Retain the cover in  
the base.  
6. Saturate the foam precleaner in clean engine oil.  
Gently squeeze it in a clean cloth to remove excess  
oil and to distribute oil (DO NOT TWIST).  
7. Install the foam precleaner into the cover, fol-  
lowed by the paper filter.  
8. Install the cover, foam precleaner and paper filter.  
9. Tighten the two screws to retain the filter in place.  
Figure 3.2 – Engine Air Cleaner  
4. With the oil drained, remove the old oil filter by  
turning it counterclockwise. Place a towel under-  
neath to catch excess oil.  
5. Apply a light coating of clean engine oil to the gas-  
ket of the new filter. Fill the filter until saturated  
with clean oil.  
6. Screw the new filter on by hand until its gasket  
lightly contacts the oil filter adapter. Then, tighten  
the filter an additional 3/4 to one turn.  
7. Remove the dipstick and wipe it dry with a clean,  
lint-free cloth. This will be used later to check the  
oil level.  
8. Remove the oil fill cap on the oil fill tube and  
slowly add the proper type and amount of recom-  
mended oil (see Specifications). Periodically use  
the dipstick to check the oil level and continue to  
fill the crankcase until the oil reaches the dipstick  
Full” mark. DO NOT FILL ABOVE THE “FULL”  
MARK.

2. Clean spark plug by scraping or washing using a  
wire brush and commercial solvent. Do not blast  
the spark plug to clean.  
3. Check the spark plug gap using a wire feeler  
gauge. Adjust the gap to 0.030 inch (0.76 mm)  
by carefully bending the ground electrode (Figure  
3.4).  
3.3.2 CLEANING OR REPLACING  
THE PAPER FILTER  
Once each year or every 100 hours of operation  
(whichever comes first), clean or replace the paper  
filter. The new replacement filter must be flame  
retardant. Service the paper filter more frequently if  
operating the generator in extremely dusty or dirty  
conditions. Use the following procedure (Figure 3.2):  
1. Followsteps1-3in"CleaningtheFoamPrecleaner";  
service the foam precleaner if necessary.  
2. Remove the paper filter.  
3. Clean the air filter by tapping it gently on a solid  
surface. If the filter is too dirty, replace it with a  
new one. Dispose of the old filter properly.  
4. Clean the air cleaner cover then reassemble follow-  
ing steps 7-9 in "Cleaning the Foam Precleaner".  
Sparking can occur if the wire terminal does not  
fit firmly on the spark plug terminal end. If nec-  
essary, re-form the wire terminal to obtain a  
tight fit.  
Figure 3.4 – Setting the Spark Plug Gap  
3.4 CLEAN AIR INTAKE  
Clean all foreign material from the air intake (Figure  
3.3) at least once every 100 hours of operation. Clean  
more often if necessary.  
Inspect the area around the generator exhaust muf-  
fler periodically and remove all grass, leaves, dirt,  
etc., from this area.  
Figure 3.3 – Cleaning Air Intake  
3.6 CLEAN SPARK ARRESTOR  
The engine exhaust muffler has a spark arrestor  
screen. Inspect and clean the screen every 50 hours  
of operation or once each year, whichever comes  
first.  
NOTE:  
If using the generator on any forest-covered,  
brush-covered or grass-covered unimproved land,  
it must equipped with a spark arrestor. The spark  
arrestor must be maintained in good condition by  
the owner/operator.  
Clean and inspect the spark arrestor as follows:  
• Remove the screen retaining bracket by removing  
the screw (Figure 3.5).  
USTC  
• Slide the spark arrestor screen out from the tail  
pipe.  
• Inspect screen and replace if torn, perforated or  
otherwise damaged. DO NOT USE a defective  
screen. If screen is not damaged, clean it with com-  
mercial solvent.  
3.5 CHECKING THE ENGINE  
SPARK PLUG  
Clean the spark plug and reset the spark plug gap  
every 100 hours of operation.  
• Replace the screen and the retaining bracket.  
1. Clean the area around the base of the spark plug  
to keep dirt and debris out of the engine. Remove  
the spark plug and check the condition. Replace  
the spark plug if worn or if reuse is question-  
able.

Do not dispose of the battery in a fire. The  
battery is capable of exploding. Storage batter-  
ies give off explosive hydrogen gas. This gas can  
form an explosive mixture around the battery  
for several hours after charging. The slightest  
spark can ignite the gas and cause an explo-  
sion. Such an explosion can shatter the battery  
and cause blindness or other injury. Any area  
that houses a storage battery must be properly  
ventilated. Do not allow smoking, open flame,  
sparks, or any spark producing tools or equip-  
ment near the battery. Discharge static electric-  
ity from body before touching the battery by  
first touching a grounded metal surface.  
3.7 CLEANING THE GENERATOR  
Keep the generator set as clean and dry as possible.  
Protect the unit against excessive dust, dirt, corrosive  
vapors, road splash, etc. Permitting dirt and mois-  
ture to accumulate on generator windings will have  
an adverse effect on the insulation resistance of those  
windings.  
When moisture is allowed to remain in contact with  
windings, some of the moisture will be retained in  
voids and cracks in the insulation. This causes a  
reduced insulation resistance and will eventually  
cause problems. Dirt will make the problem worse,  
since dirt tends to hold moisture in contact with  
windings. Salt (as from sea air) also will worsen the  
problem since it tends to absorb moisture from the  
air. Salt and moisture, when combined, form a good  
electrical conductor which can be damaging to the  
generator windings.  
A battery presents a risk of electrical shock  
and high short circuit current. The following pre-  
cautions are to be observed when working on  
batteries:  
• Remove watches, rings or other metal objects;  
• Use tools with insulated handles;  
• Wear rubber gloves and boots;  
• Do not lay tools or metal parts on top of the  
battery;  
• Disconnect any charging source prior to connecting  
or disconnecting battery terminals; and  
• Do not use any jumper cables or booster battery to  
crank and start the generator engine. If any battery  
has discharged, remove it for recharging.  
Do NOT use a forceful spray of water to clean  
the generator. Water will enter the generator  
interior and cause problems, and may also con-  
taminate the generator fuel system.  
3.8 BATTERY MAINTENANCE  
All lead-acid batteries will discharge when not in  
use. The generator battery should be inspected as  
follows:  
Do not open or mutilate the battery. Released

thoroughly and immediately with water and seek  
medical attention; and  
3.11.2 RETURN TO SERVICE  
To return the unit to service after storage, proceed  
as follows:  
• Spilled electrolyte is to be washed down with an  
acid neutralizing agent. A common practice is to  
use a solution of 1 pound (500 grams) bicarbonate  
of soda to 1 gallon (4 liters) or water. The bicar-  
bonate of soda solution is to be added until the  
evidence of reaction (foaming) has ceased. The  
resulting liquid is to be flushed with water and the  
area dried.  
1. Check the tag on the engine for oil viscosity and  
classification. Verify that the correct recommend-  
ed oil is used in the engine (see Specifications). If  
necessary, drain and refill with the proper oil.  
2. Check the state of the battery. Fill all cells of  
unsealed batteries to the proper level with dis-  
tilled water. DO NOT USE TAP WATER IN THE  
BATTERY. Recharge the battery to 100 percent  
state of charge, or, if defective, replace the battery.  
3. Clean and wipe the entire generator.  
4. Reconnect the battery. Observe battery polarity.  
Damage may occur if the battery is connected  
incorrectly.

sary and then start the engine.  
6. Allow the unit to run for several minutes to warm  
up.  
7. Apply electrical loads to at least 50 percent of the  
unit’s rated wattage capacity.  
8. When the engine is thoroughly warmed up, shut  
it down.  
9. The generator is now ready for service.  
3.11 OUT OF SERVICE PROCEDURE  
3.11.1 REMOVAL FROM SERVICE  
3.12 ADJUSTING VALVE CLEARANCE  
After the first 50 hours of operation, adjust the valve  
clearance in the engine.  
If the generator cannot be exercised every seven days,  
and it is to be out of service longer than 30 days, pre-  
pare the generator for storage as follows:  
When adjusting valve clearance, the engine should be  
at room temperature and the piston should be at Top  
Dead Center (TDC) of its compression stroke (both  
valves closed). Correct clearance is 0.001-0.003 inch  
(0.03-0.07mm). Adjust valve clearance as follows:  
1. Start the engine and let it warm up.  
2. Close the fuel shutoff valve in the fuel supply line  
and allow the unit to shut down.  
NOTE:  
Using a fuel additive such as STA-BIL fuel stabi-  
lizer, or an equivalent, will prevent gum deposits  
from forming in the engine’s fuel system.  
1. Loosen the rocker arm jam nut. Use an allen  
wrench to turn the pivot ball stud while checking  
clearance between the rocker arm and the valve  
stem with a feeler gauge (Figure 3.6).  
3. While the engine is still warm from running, drain  
the oil completely. Refill the crankcase with SAE  
10W-30 oil having API classification “For Service  
SF.”  
Figure 3.6 — Adjusting Valve Clearance  
4. Attach a tag to the engine indicating the viscosity  
and classification of the oil in the crankcase.  
5. Remove the spark plug and pour two or three  
tablespoons of clean, fresh engine oil into the  
spark plug threaded openings. Reinstall and  
tighten the spark plug.  
6. Remove the battery and store it in a cool, dry  
room on a wooden board. Never store the battery  
on any concrete or earthen floor.  
7. Clean and wipe the entire generator.

products described in this manual. The manufac-  
turer assumes that installation personnel are familiar  
with the procedures for installing such products, or  
similar products manufactured. The manufacturer  
also assumes that personnel have been trained in  
the recommended installation procedures for these  
products and that such training includes (a) use of  
common hand tools, (b) use of special tools, and (c)  
use of any tools and/or equipment from other sup-  
pliers.  
GENERAL HAZARDS  
For safety reasons, the manufacturer recommends  
that the installation, initial start-up and main-  
tenance of this equipment is carried out by an  
Authorized Service Dealer.  
• The engine exhaust fumes contain carbon monox-  
ide, which can be DEADLY. This dangerous gas, if  
breathed in sufficient concentrations, can cause  
unconsciousness or even death. This exhaust  
system must be installed properly, in strict com-  
pliance with applicable codes and standards.  
Following installation, do nothing that might ren-  
der the system unsafe or in noncompliance with  
such codes and standards. The generator com-  
partment must be completely vapor sealed from  
the vehicle interior. There must be no possibility of  
exhaust fumes entering the vehicle interior. Never  
operate this equipment with a leaking or defective  
exhaust system.  
• Keep hands, feet, clothing, etc., away from drive  
belts, fans, and other moving or hot parts. Never  
remove any drive belt or fan guard while the unit  
is operating.  
• Adequate, unobstructed flow of cooling and ven-  
tilating air is critical to correct generator opera-  
tion and is required to expel toxic fumes and fuel  
vapors from the generator compartment. Without  
sufficient cooling airflow, the engine/generator  
quickly overheats, which causes serious damage  
to the generator. Do not alter the installation or  
permit even partial blockage of ventilation provi-  
sions, as this can seriously affect safe operation of  
the generator.  
The manufacturer cannot possibly know of and  
advise the recreational vehicle trade of all conceiv-  
able methods, procedures or techniques by which to  
perform an installation. Nor can the manufacturer  
anticipate every possible hazard that might result  
from each installation method, procedure or tech-  
nique. The manufacturer has not undertaken any  
such wide evaluation. If using a procedure, work  
method or operating technique the manufacturer  
does not specifically recommend, ensure that it is  
safe for others. Also make sure the procedure, work  
method or operating technique utilized does not ren-  
der the generator unsafe.  
Information, illustrations, specifications, etc., con-  
tained in these Installation Instructions are based on  
the latest information available at the time of publica-  
tion. Every effort has been expended to be sure that  
such data is both accurate and current. However, the  
manufacturer reserves the right to change, alter or  
otherwise improve this product at any time without  
prior notice.  
DANGER  
• When working on this equipment, remain alert  
at all times. Never work on the equipment when  
physically or mentally fatigued.  
• Before performing any maintenance on the gen-  
erator, disconnect its battery cables to prevent  
accidental start up. Disconnect the cable from the  
battery post indicated by a NEGATIVE, NEG or (–)  
first. Reconnect that cable last.  
Despite the safe design of this generator,  
operating this equipment imprudently, neglecting  
its maintenance or being careless can cause  
possible injury or death. Permit only responsible  
and capable persons to operate or maintain this  
equipment.  
• Never use the generator or any of its parts as a  
step. Stepping on the unit can stress and break  
parts, and may result in dangerous operating con-  
ditions from leaking exhaust gases, fuel leakage,  
oil leakage, etc.  
• Never insert any tool or other object through open-  
ings in the generator interior, even if the unit is not  
running; damage to the equipment, or a serious  
injury may occur.  
Potentially lethal voltages are generated by  
these machines. Ensure all steps are taken to  
render the machine safe before attempting to  
work on the generator.  
Parts of the generator are rotating and/or hot  
during operation. Exercise care near running  
generators.

ELECTRICAL HAZARDS  
FIRE HAZARDS  
• The generator covered by this manual produces  
dangerous electrical voltages and can cause fatal  
electrical shock. Avoid contact with bare wires, ter-  
minals, connections, etc., while the unit is running.  
Ensure all appropriate covers, guards and barriers  
are in place before operating the generator. If work  
must be done around an operating unit, stand on  
an insulated, dry surface to reduce shock hazard.  
• Do not handle any kind of electrical device while  
standing in water, while barefoot, or while hands or  
feet are wet. DANGEROUS ELECTRICAL SHOCK  
MAY RESULT.  
• During installation onto the vehicle, properly  
ground (bond) the generator either by solid mount-  
ing to the vehicle frame or chassis, or by means of  
an approved bonding conductor. DO NOT connect  
the bonding conductor to any generator part that  
might be removed or disassembled during routine  
maintenance. If the grounding conductor must be  
replaced, use only a flexible conductor that is of  
No. 8 American Wire Gauge (AWG) copper wire  
minimum.  
For fire safety, the generator must be installed  
and maintained properly. Installation always must  
comply with applicable codes, standards, laws  
and regulations. Adhere strictly to local, state and  
national electrical and building codes. Comply  
with regulations the Occupational Safety and  
Health Administration (OSHA) has established.  
Also, ensure that the generator is installed in  
accordance with the manufacturer’s instructions  
and recommendations. Following proper installa-  
tion, do nothing that might alter a safe installation  
and render the unit in noncompliance with the  
aforementioned codes, standards, laws and regula-  
tions.  
• Keep a fire extinguisher in the vehicle at all times.  
Extinguishers rated ABC” by the National Fire  
Protection Association are appropriate for use on  
the recreational vehicle generator electrical system.  
Keep the extinguisher properly charged and be  
familiar with its use. If ther are any questions per-  
taining to fire extinguishers, consult the local fire  
department.  
• If the vehicle electrical circuits can be powered by  
any other source of electricity (such as a “dockside”  
power receptacle), there must be no possibility of  
connecting the different power sources to the vehi-  
cle circuits at the same time. The dockside (utility)  
power source must be positively isolated from the  
vehicle circuits whenever the generator is operat-  
ing. Failure to isolate the vehicle circuits from  
the dockside power supply when the generator is  
running may result in damage to the generator or  
serious injury or death to dockside (utility) power  
workers due to backfeed of electrical energy.  
• In case of accident caused by electric shock, imme-  
diately shut down the source of electrical power.  
If this is not possible, attempt to free the victim  
from the live conductor. AVOID DIRECT CONTACT  
WITH THE VICTIM. Use a nonconducting imple-  
ment, such as a rope or board, to free the victim  
from the live conductor. If the victim is uncon-  
scious, apply first aid and get immediate medical  
help.  
EXPLOSION HAZARDS  
• Do not smoke around the generator. Wipe up any  
fuel or oil spills immediately. Ensure that no com-  
bustible materials are left in the generator com-  
partment, or on or near the generator, as FIRE or  
EXPLOSION may result. Keep the area surround-  
ing the generator clean and free from debris.  
• Gasoline is extremely FLAMMABLE and its vapors  
are EXPLOSIVE. Do not permit smoking, open  
flame, sparks or any source of heat in the vicinity  
while handling gasoline. Comply with all laws gov-  
erning the storage and handling of gasoline.  
Fuel lines must be properly installed and fastened,  
and free of leaks. There must be no possibility of  
gasoline vapors entering the vehicle interior.  
• It is required that an approved, flexible, noncon-  
ductive fuel line be installed between the generator  
fuel connection point and rigid fuel lines.  
• Never wear jewelry when working on this equip-  
ment. Jewelry can conduct electricity resulting in  
electric shock, or may get caught in moving com-  
ponents causing injury.

Section 2 – Installation  
Recreational Vehicle Generator  
The generator can be installed so that it sits on top  
of the horizontal support tubing if the vehicle design  
permits. Another method is to suspend the genera-  
tor below the horizontal support tubing by means of  
suitable, structurally sound metal framework. The  
following general rules apply:  
2.1 LOCATION AND SUPPORT  
2.1.1 GENERATOR LOCATION  
The most desirable location for the generator set is  
between the vehicle's main frame members. However,  
this is seldom possible. Most units must be installed  
on the side of the vehicle and are difficult to rein-  
force.  
Vehicle construction MUST be capable of support-  
ing the weight of the generator.  
• Whether the generator is mounted above the hori-  
zontal support tubing or suspended below the tub-  
ing, the supporting frame used must be structur-  
ally sound.  
• If the generator cannot be bolted directly to  
the supporting frame or support tubing, con-  
sider using additional tubing, angle brackets  
or other supports to give the supporting frame suf-  
ficient strength.  
Many recreational vehicles have been factory equipped  
with an area for the generator set. Some vehicles may  
even have a generator compartment provided by the  
vehicle manufacturer.  
Plan the generator location based on the following:  
• The generator set must be installed on a frame-  
work that is part of the recreational vehicle, as  
outlined in the "Generator Support" section.  
• The location must provide an access opening  
that is large enough to permit generator removal  
(unless the generator is to be removed from under-  
neath the supporting framework).  
Figure 2.1 – Typical Horizontal Support Frame  
• The location must provide easy access to frequent-  
ly serviced components, such as filters, oil drains,  
spark plugs and other common maintenance  
parts.  
• The location must provide sufficient room to allow  
minimum clearances as outlined in "Generator  
Compartments". If sound insulation is to be used  
on the compartment walls and ceiling, the mini-  
mum recommended applies to the space between  
the generator and such insulation.  
• The location must provide adequate cooling and  
ventilating airflow for the generator without a great  
deal of work and expense.  
• If mounting the generator in an enclosed compart-  
ment, the base of the generator must rest flat on  
the floor without any gaps.  
• When using a suspended mounting system, ensure  
the base of the generator is flush with the sur-  
rounding bodywork. If the unit is mounted higher  
in the structure, heated air may recirculate into the  
generator causing it to overheat.  
2.1.4 GENERATOR RESTRAINT  
Use four 5/16"-18 hardened steel bolts (Grade 5) to  
fasten the generator to the supporting frame or the  
support tubing. These bolts must pass through (a)  
the generator mounting base, (b) the compartment  
floor (if a compartment is used) and (c) the support-  
ing framework (Figure 2.2). All bolts must be long  
enough so that when tight, at least three threads  
are visible past the retaining lock nuts. Refer to  
"Generator Compartments" for the location of the  
generator mounting holes.  
Figure 2.2 – Typical Generator Restraint  
2.1.2 GENERATOR SUPPORT  
The generator must be securely attached to a metal  
framework that has been made part of the vehicle  
frame structure by bolting or welding. The metal  
framework on which the generator will rest and  
which will restrain the generator set should consist  
of at least two horizontal beams. These beams should  
consist of (a) 1-1/2-inch square, 11-gauge steel tub-  
ing OR (b) 1-1/2-inch, 11-gauge angle iron. A typical  
supporting frame with horizontal support tubing, is  
shown in Figure 2.1.

Figure 2.4 – Typical Compartment Construction  
2.2 GENERATOR COMPARTMENTS  
Whether the generator set is being installed inside a  
compartment specifically manufactured to house a  
generator or inside a compartment that the installer  
constructs, the compartment must meet certain spec-  
ifications as outlined in the following sections:  
2.2.1 COMPARTMENT SIZE  
Plan the compartment size carefully. Provide a mini-  
mum clearance of 1/2 inch (13 mm) on the front and  
top, 1/2 inch (13 mm) on the left side, two (2) inches  
on the right side, and 2-1/2 inch (63.5 mm) from the  
back for air circulation AFTER the compartment has  
been lined with metal and sound insulation (Figure  
2.3).  
Figure 2.3 – Clearances  
Plywood  
Compartment  
1/2" Clearance on Top  
• All seams, splices and joints of the compart-  
ment walls (unless vapor tight by design) should  
be caulked to prevent poisonous, flammable or  
explosive vapors from entering the vehicle inte-  
rior.  
2-1/2" Clearance

Caulking must be done so that the caulking mate-  
rial will stay in place permanently. Pressing such  
materials as putty tape onto joints and seams is  
NOT acceptable. A high quality silicone rubber base  
sealant is recommended.  
1/2" Left Side  
• Holes and openings made in the compartment  
walls to allow for the passage of electrical conduit,  
conductors, hoses, cables, etc., into the vehicle liv-  
ing area must be sealed vapor tight with silicone  
rubber base sealant.  
NOTE:  
Refer to “Figure 1.2 – Major Features and  
Dimensions”.  
2.2.2 COMPARTMENT CONSTRUCTION  
• If flexible metal conduit is used, it must be sealed  
internally at the end where it terminates inside the  
compartment’s electrical junction box.  
NOTE:  
• The generator compartment should be either con-  
structed of, or lined with, 26-gauge galvanized  
steel.  
Flexible metal conduit, due to its unique construc-  
tion, is NOT vapor tight along its entire length.  
NOTE:  
Aluminum is NOT an acceptable alternative to  
galvanized steel due to aluminum’s low melting  
point.  
• Seams and joints of the galvanized steel (whether  
used as a liner or for the compartment itself) must  
be lapped and mechanically secured. Such seams  
may be manufactured, welded, bolted, riveted or  
screwed. Manufactured lock seams are shown in  
Figure 2.5. Installer constructed compartments  
typically utilize a standard lap joint.  
• After the compartment has been metal lined and  
vapor sealed, line the compartment interior walls  
and ceiling with an approved, nonflammable sound  
insulating material.  
• If the compartment is lined with galvanized steel,  
it may be constructed of any material. The manu-  
facturer recommends that the compartment be  
constructed of 1/2-inch thick plywood (not strand-  
board), with the floor made of a double thickness  
of 1/2-inch plywood with the grain of the wood at  
cross section for added strength (Figure 2.4).  
• If constructing a compartment, line the exterior  
(underside) of the compartment floor with 26-  
gauge galvanized steel.

Recreational Vehicle Generator  
NOTE:  
Figure 2.5 – Types of Lock Seams  
Any method used to reduce noise must not  
adversely affect the flow of cooling and ventilating  
air into or out of the compartment.  
In addition to the effective use of sound insulating  
materials, construction of a special noise abatement  
compartment might be considered to reduce noise  
levels. Such a compartment might be constructed as  
follows (Figure 2.6):  
• Use 5/8-inch thick or 3/4-inch thick plywood in the  
compartment.  
• Construct the compartment floor of a double thick-  
ness of 5/8-inch or 3/4-inch plywood.  
• Line the compartment interior walls and floor, as  
well as the underside of the floor, with 26-gauge  
galvanized steel.  
Vapor seal all compartment seams and joints.  
• Over the galvanized steel lining, install a combina-  
tion of acoustical materials.  
DANGER  
Do not install any flammable material directly  
above or around the compartment. Heat, trans-  
ferred through the compartment structure, may  
be sufficient to ignite, char or discolor seat cush-  
ions, fiberboard and other flammable materials.  
Use approved nonflammable insulating materi-  
als in high temperature areas.  
DANGER  
To prevent fire or explosion, do not install any  
interior or underside of the compartment floor.  
• Seal all compartment door edges to prevent noise  
leakage around the door perimeter.  
• Line the compartment door interior (except for air  
openings) with suitable, fireproof sound insulation  
(such as 1-inch (25 mm) thick fiberglass with a 2-  
pound density).  
insulation or other absorbent materials on the  
2.2.3 SOUND INSULATING MATERIALS  
Once installers have determined that a compartment  
is properly constructed and metal lined, they can add  
acoustical material. This may include additional seal-  
ant or insulating material, to reflect noise away from  
the vehicle interior.  
Sound insulating materials should be of a nonflam-  
mable type. One excellent insulating material is a 1-  
inch (25 mm) thick fiberglass having a 2-pound den-  
sity. When fiberglass is used, its coated side should  
face toward the compartment interior.  
Figure 2.6 – Typical Noise Abatement  
DANGER  
Do not install sound insulation or any absorbent  
material on the compartment floor interior. Such  
materials will become soaked with combustible  
or explosive vapors and liquids and will become  
a fire hazard.  
Using a combination of sound insulating materials  
can often reduce noise more effectively than a single  
material. For example, a sheet of lead or visco-elastic  
material, along with a layer of other acoustical mate-  
rial, is more effective than when a single material is  
used.  
2.2.5 COMPARTMENT FLOOR CUTOUTS  
2.2.4 ACOUSTICS  
Provide openings in the generator compartment for  
the following items (Figure 2.7):  
For additional noise abatement, the installer may  
wish to consider the following:  
• Engine exhaust and cooling air outlets  
• Generator cooling air inlet  
Four holes for passage of generator mounting  
• Using special sound insulating materials.  
• Construction of a special noise abatement com-  
partment.

Recreational Vehicle Generator  
2.3.2 TESTING THE INSTALLATION  
DANGER  
The manufacturer recommends testing the installa-  
tion to be sure adequate cooling airflow is available to  
the unit before placing the unit into service. If the unit  
shows signs of overheating, enlarge the air openings.  
Never place a unit into service until absolutely certain  
that cooling and ventilation is adequate.  
Fuel lines and exhaust piping must not pen-  
etrate into the vehicle living area.  
2.3 COOLING AND VENTILATING AIR  
It is absolutely essential that an adequate flow of  
air for cooling, ventilating and engine combustion  
be supplied to the generator set. Without sufficient  
airflow, the engine/generator quickly overheats. Such  
overheating can cause serious operating difficulties  
and also may cause fire and personal injury. The  
installer must make sure that sufficient air is avail-  
able to the generator for cooling, ventilating and  
combustion. The installer also must provide for a  
path for exhausting the cooling air to the exterior of a  
compartment, if so equipped.  
NOTE:  
Test the installation, especially if bringing in air  
from below the generator set.  
2.4 LP GAS FUEL SYSTEM  
DANGER  
LP gas is highly EXPLOSIVE. The gas is heavier  
than air and tends to settle in low areas. Even  
the slightest spark can ignite it and cause and  
explosion. Only competent, qualified people  
should be allowed to install, test, adjust or ser-  
vice an LP gas fuel system. Install the optional  
fuel system in compliance with applicable codes,  
standards and regulations. After the installation,  
do not do anything that might render the sys-  
tem in noncompliance with applicable codes and  
standards.  
DANGER  
Never use discharged cooling air for heating or  
permit such air to enter the vehicle interior. This  
air contains deadly carbon monoxide gas and  
other poisonous, flammable or explosive gases.  
2.3.1 GENERATOR AIRFLOW  
Engine operation drives cooling fans for the two-stage  
cooling air system. A pressure fan draws cooling air  
into the bottom right side of the generator (Figure  
2.8). This airflow cools the engine/generator and elec-  
tronic components. The second part of the cooling  
system, a suction fan, draws air that is heated from  
a hot engine into a collector compartment at the left  
side of the unit. This heated air (although cooler than  
exhaust muffler) is then deflected out the bottom  
toward the ground.  
The LP powered range of generators are fitted with a  
nonadjustable, factory set system. These systems are  
tamper-proof to meet 1997 California Air Resources  
Board requirements for engine emission.  
2.4.1 PARTS NOT INCLUDED IN FUEL  
SYSTEM  
The propane fuel system does NOT include such  
items as (a) gas tank, (b) gas piping, (c) fittings, (d)  
valves, and (e) primary regulator, used to store the  
gaseous fuel and deliver it to the gaseous fuel sole-  
noid (Figure 2.9).  
Figure 2.8 – Airflow Through Engine/Generator  
DANGER  
Use only approved components in the fuel sup-  
ply system. All components must be properly  
installed in accordance with applicable codes.  
Improper installation or use of unauthorized  
components may result in fire or an explosion.  
Follow approved methods to test the system for  
leaks. No leakage is permitted. Do not allow fuel  
vapors to enter the vehicle interior.

Section 2 – Installation  
Recreational Vehicle Generator  
Figure 2.9 – Typical Propane Gas Fuel System  
2.4.4 PRIMARY REGULATOR  
Gas pressure delivered to the solenoid valve must be  
properly regulated by means of a primary gas regu-  
lator. Mount the primary regulator at the gas tank  
outlet or in the supply line from the gas tank. The  
following rules apply:  
For best results, the primary regulator supplies  
gaseous fuel to the secondary regulator at 11 inch-  
es water column. Do NOT exceed 14 inches water  
column.  
• The installer must be sure the primary regulator is  
rated at sufficient gas flow to operate the generator  
plus all other gas appliances in the circuit.  
NOTE:  
Recommended MINIMUM gas flow rate for these  
air-cooled generators is 40 cubic feet per hour.  
If an existing primary gas regulator does not have  
a sufficient flow capacity for the generator and  
other gas appliances in the circuit, (a) install a  
primary regulator with adequate flow rate, or (b)  
install a separate regulator only and rated at least  
40 cubic feet per hour. The inlet side of any pri-  
mary regulator that supplies the generator must  
connect directly to a gas pressure tank. Do NOT  
tee the generator line into a gas circuit feeding  
other areas.  
2.4.2 SOME IMPORTANT CONSIDERATIONS  
When installing an LP gas system, consider seriously  
the following items:  
2.4.5 GASEOUS CARBURETION  
LP gas vapors should be supplied to the secondary  
regulator inlet at about 11 inches water column (posi-  
tive pressure). The engine pistons draw air in dur-  
ing the intake stroke (Figure 2.10). This air passes  
through a carburetor venturi, which creates a low  
pressure that is proportional to the quantity of air  
being pumped. The low pressure from the carburetor  
venturi acts on the regulator diaphragm to pull the  
diaphragm toward the source of low pressure. A lever  
attached to the diaphragm opens a valve to permit  
gas glow through the carburetor.  
• All fittings, lines, hoses and clamps must be  
tight and free of leaks. Apply a pipe sealant to  
threads when assembling threaded connections.  
This reduces the possibility of leakage.  
Test the entire fuel system for leaks using approved  
test methods.  
• Optimum gas pressure at the inlet to the gaseous  
fuel solenoid valve and secondary regulator is 11  
inches water column.  
• The installer’s fuel supply connection point is at  
the gaseous fuel solenoid valve. This is a 3/4-inch  
(female) connection. Provide a suitable 3/4-inch  
NPT (male) connector to attach to the fuel supply  
line.  
Figure 2.10 – LP Gas Carburetion Diagram  
• Use a length of approved flexible fuel hose between  
the gaseous fuel solenoid valve and rigid gas pip-  
ing. The flexible line should be at least 6 inches  
longer than necessary.  
2.4.3 VAPOR WITHDRAWAL  
LP gas is stored in pressure tanks as a liquid. The  
gas systems used with these generators were designed  
only for vapor withdrawal type systems. Vapor with-  
drawal systems use the gas vapors that form above  
the liquid fuel in the tank. Do NOT attempt to use the  
generator with any liquid withdrawal type system.

turi, the lower the pressure at the venturi throat. The  
lower the pressure at the venturi throat, the greater  
the diaphragm movement, and the greater the move-  
ment of the regulator valve. The more the regulator  
valve opens, the greater the gas flow that is propor-  
tional to airflow through the generator.  
The leak test must comply fully with NFPA, Paragraph  
318. All connections, hoses, valve regulators, fittings,  
and other fuel system parts must be tested under  
gas or air pressure of not less than 90 psi (620 kPa),  
while using soap and water or an equivalent solution  
to check for leaks. Other approved methods of testing  
for leaks may be used, if appropriate. DO NOT USE  
ANY FLAME TO TEST FOR LEAKS.  
The following facts about the secondary regulator  
must be emphasized:  
DANGER  
• The regulator must be sensitive to venturi throat  
pressure changes throughout the operating range.  
• The regulator must be properly adjusted so it will  
stop the flow of gas when the engine is not running  
(no air flow through the carburetor).  
• The slightest airflow (and vacuum in the venturi  
throat) should move the regulator valve off its seat  
and permit gas to flow.  
Gaseous fuel lines between the tank and the  
secondary regulator are under a positive pres-  
sure (about 11 inches water column). Gas pres-  
sure at the outlet side of the secondary regula-  
tor, however, is a negative pressure and can  
draw flame inside a line or fitting and cause an  
explosion.  
2.4.6 FUEL SUPPLY LINES  
2.5 EXHAUST SYSTEM  
The generator exhaust system must be safely and  
properly installed. Only approved mufflers and other  
exhaust system parts must be used. A properly  
installed exhaust system must be vapor tight, quiet  
and completely safe.  
• LP gas lines must be accessible, but protected  
against possible damage.  
• Do NOT connect electrical wiring to any LP gas fuel  
line or run wiring alongside the lines.  
• Route gas lines away from hot engine exhausts.  
• Retain gas lines with metal clamps that do not have  
sharp edges.  
DANGER  
• Install an approved length of flexible hose between  
the gaseous fuel solenoid valve and rigid fuel  
supply lines. The flexible line must be nonmetal-  
lic, nonorganic and nonconductive. It must be  
approved for use with LP gas.  
The generator engine gives off DEADLY carbon  
monoxide gas through its exhaust system. This  
dangerous gas, if breathed in sufficient con-  
centrations, can cause unconsciousness or even  
death. Never operate the generator set with  
the vehicle inside any garage or other enclosed  
area. DO NOT OPERATE THE GENERATOR IF THE  
EXHAUST SYSTEM IS LEAKING OR HAS BEEN  
DAMAGED. SYMPTOMS OF CARBON MONOXIDE  
POISONING ARE (a) inability to think coher-  
ently; (b) vomiting; (c) twitching muscles; (d)  
throbbing temples; (e) dizziness; (f) headaches;  
(g) weakness; and (h) sleepiness. IF FEELING  
ANY OF THESE SYMPTOMS, MOVE INTO FRESH  
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET  
MEDICAL HELP. Do not operate the generator  
until its exhaust system has been inspected and  
properly repaired.  
2.4.7 EXCESS FLOW VALVE  
LP gas tanks should have an excess flow valve,  
according to NFPA 501C, Paragraph 3-4.4. This  
valve and the gas lines must be carefully sized so the  
valve will close when a fuel line is severed or broken.  
Consult the Natural-LP Gas Association for informa-  
tion and limitations of excess flow valves.  
Manual shutoff valves on the supply tank and else-  
where in the system must be fully open when oper-  
ating the generator. The excess flow valve functions  
properly only if all valves are fully open.  
2.4.8 LEAKAGE TESTS  
Never tee the generator engine exhaust pipe  
Do not place the generator into service until the gas  
system has been properly tested for leaks. To test the  
system, a separate source of 12 volts DC is needed to  
open the gaseous fuel solenoid valve.  
into the vehicle engine exhaust piping. This  
causes excessive back pressure on the generator  
engine. Also, water from one engine can dam-  
age the other engine.

2.5.1 SPARK ARRESTOR  
2.5.2 EXHAUST SYSTEM SAFETY  
This spark arrestor assembly meets code and stan-  
dard requirements of the U.S. Forest Service. Use  
only mufflers and parts approved by the manufactur-  
er. Any person(s) installing an unapproved muffler, or  
an unapproved exhaust system part, or modifying an  
exhaust system in any way that might cause a hazard,  
is liable for any damage, injury or warranty expense  
that might be caused by such unapproved installation  
or modification.  
• Maintain a clearance of at least 3 inches (76 mm)  
between exhaust system parts and any combus-  
tible material (such as wood, felt, cotton, organic  
fibers or other like material). If the 3-inch (76 mm)  
clearance cannot be maintained, locate, insulate or  
shield the exhaust part(s) so that the temperature  
of any combustible material is not raised more  
than 117° F (65° C) above the ambient air tempera-  
ture.  
• Extend the exhaust system at least 1 inch (25 mm)  
past the outer edge of the vehicle. Do not terminate  
the exhaust system under the vehicle.  
Terminate the exhaust tailpipe such that exhaust  
gases will not be drawn back into the generator  
compartment and recirculated.  
Failure to provide and maintain a spark arrestor may  
be in violation of the law. If this generator is used on  
any forest covered, brush covered or grass covered  
unimproved land, provide a spark arrestor. The vehi-  
cle owner or operator must maintain this device in  
good condition. In the state of California, the preced-  
ing is required by law (Section 4442 of the California  
Public Resources Code). Other states may have simi-  
lar laws. Federal laws apply on federal lands.  
• If there is any possibility of the tailpipe or muffler  
being damaged, protect these damage-prone areas  
by means of a protective device (such as a skid  
bar).  
• Install the generator exhaust system according to  
When installing/replacing the tailpipe or spark arres-  
tor components, verify that the tailpipe has a hole  
to securely fasten the spark arrestor components  
(see Figures 2.11 and 2.12). Use only manufacturer  
supplied hardware. Substitution of parts may cause  
damage to the screen or a loose fit to the tailpipe.  
safe automotive practices.  
• Use enough exhaust system hangers to prevent any  
part of the system from being dislocated.  
• Use exhaust system parts recommended by the  
manufacturer. Using unapproved exhaust mufflers  
and exhaust system parts is the responsibility of  
the person(s) installing such unauthorized parts.  
• Do not terminate the exhaust system under any  
opening, window or vent that can be opened or is  
not permanently sealed from the vehicle interior.  
• Exhaust piping must be large enough to prevent  
excessive back pressure on the generator engine.  
• Never tee the generator engine exhaust pipe into  
the vehicle engine exhaust piping. This causes  
excessive back pressure on the generator engine.  
Also, water from one engine can damage the other  
engine.

The following general rules apply to electrical connec-  
tions in a recreational vehicle:  
• Qualified electricians who are familiar with appli-  
cable codes, standards and regulations should  
install electrical wiring.  
• The wiring should comply with codes, standards  
and regulations. The National Electrical Code  
(NFPA 70), and state and local codes apply.  
• Switches and circuit breakers should be of a type  
approved for use in recreational vehicles and must  
be mounted and installed to prevent damage from  
road shock.

• Wiring must be of adequate size, have approved  
insulative qualities and be properly supported.  
• Conduit and wire openings into the generator com-  
partment (if used) must be vapor-sealed to prevent  
entry of flammable, explosive or poisonous gases  
into the vehicle.

2.6.1 ELECTRICAL JUNCTION BOX  
Install an approved, square electrical junction box  
with a blank cover on the interior or exterior wall  
of the area planned for installation of the generator  
(NOT on the generator). Route the generator's AC  
output leads into this junction box through approved  
flexible conduit. This is the point of first termination  
for generator AC output leads.  
2.6.2 WIRING  
• Wiring should be of stranded copper to reduce the  
chance that vibration may cause breakage.  
• Wire gauge size should be large enough to handle at  
least 115 percent of the installed generator's rated  
maximum current.  
Do NOT connect electrical loads in excess of any  
circuit breaker rating or problems with circuit  
breaker tripping will develop, which causes a  
loss of AC output. Also, do NOT exceed the gen-  
erator's rated wattage capacity. Add the watts  
or amperes of all lighting, appliance, tool and  
motor loads the generator will operate at one  
time. This total should be less than the unit's  
rated wattage/amperage capacity.  
• Neutral conductors must be the same size as other  
leg wires.  
• Route power supply conductors from generator AC  
output leads (white), (black) and the green ground  
wire through approved flexible conduit to the elec-  
trical junction box on the compartment wall.  
If flexible metal conduit is used between the gen-  
erator and the compartment junction box, the con-  
duit end that terminates the compartment junction  
box must be vapor-sealed. Flexible metal conduit  
is NOT vapor tight along its entire length.  
• From the junction box, route power supply wires  
through approved conduit to either (a) double-pole,  
double-throw transfer switch, or (b) approved iso-  
lation receptacle. Connecting to a transfer switch  
or isolation receptacle must prevent vehicle electri-  
cal circuits from being connected to two different  
power supplies at the same time (such as genera-  
tor and dockside power).  
2.6.4 CONDUIT  
Route the connections between the generator and the  
junction box through approved, flexible conduit. The  
following general rules apply:  
• Cut wiring to the required length and allow extra  
wire for junction box connections.  
• Carefully prepare conduit ends to prevent sharp  
edges from cutting through wiring insulation.  
• Route conduit so it does not interfere with genera-  
tor movement.  
• If using metallic conduit, vapor seal the end of the  
conduit where it enters the junction box. Do this  
because flexible metallic conduit is not vaporproof  
along its entire length.  
• Conductors must be rated 221° F (105° C) or must  
be of a larger conductor size.  
2.6.3 GENERATOR AC CONNECTIONS  
Generator AC output leads (BLACK) “hot” and  
(WHITE) grounded neutral come out of the generator  
as shown in Figure 2.13. There is also a green lead  
that connects to ground in the junction box of the  
recreational vehicle.  
2.6.5 ISOLATING DIFFERENT POWER  
SOURCES  
Connections from the junction box must terminate in  
a double-pole, double-throw transfer switch (Figure  
2.14). An alternate method for isolating different  
power sources is by using an isolating receptacle  
(Figure 2.15). Whichever method is used, be certain  
that both power sources are NOT connected at the  
same time.  
Leads BLACK to WHITE are protected against over-  
load by a 30-amp circuit breaker (CB1). Use this  
line-to-neutral connection separately to operate 120-  
volt, single-phase, 60 Hertz, AC loads requiring up to  
3,400 watts (3.4 kW) of power.

tery with a larger capacity may be needed.  
2.7.4 BATTERY COMPARTMENT  
2.7.2 BATTERY CABLES  
Install the generator battery in its own, vented com-  
partment. Place the battery compartment away from  
any source of heat, sparks or flame.  
Using battery cables that are too long or too small in  
diameter may cause a drop in voltage, which causes  
starting problems. For the best cold weather starting,  
the voltage drop between battery terminals and the  
generator connection point should not exceed 0.12  
volts per 100 amperes of cranking current.  
Provide ventilation openings in the battery compart-  
ment. The minimum size of openings should be 2  
square inches at the top of the compartment. Mount  
the battery on a strong, rigid supporting structure,  
where leaks and spills of battery fluid will not cause  
damage.  
These generators are rated at about 100 DC amperes  
of cranking current.  
Select battery cables based on (a) cable length and  
(b) prevailing ambient temperatures. Generally, the  
longer the cable and the colder the weather, the larger  
the cable size must be, as shown in the following  
chart.  
2.8 OPTIONAL ACCESSORIES  
A plug-in receptacle (Figure 2.17) is provided on  
the generator set. Use this receptacle to connect an  
optional remote-mounted start/stop panel to the  
generator. Installation of such a panel will permit  
starting and stopping the generator engine from any  
convenient location inside the vehicle.

3.3 INITIAL START  
When absolutely certain that the unit has been prop-  
erly installed and prepared for use, start the engine  
as follows:  
1. Turn off all electrical loads. Do this by setting the  
generator’s main circuit breakers to their “OFF”  
(or open) position.  
2. Refer to Part I, section “Starting the Generator”,  
for cranking and starting instructions. The engine  
may require more cranking for initial starting  
since the fuel lines have to be primed (use of the  
primer switch will shorten this time).

Recreational Vehicle Generator  
CALIFORNIA AND FEDERAL EMISSION CONTROL WARRANTY STATEMENT  
YOUR WARRANTY RIGHTS AND OBLIGATIONS  
The California Air Resources Board (CARB) and the United States Environmental Protection Agency (EPA), together with  
Generac Power Systems, Inc. (Generac), are pleased to explain the Emission Control System Warranty on your new engine.*  
New utility, and lawn and garden equipment engines must be designed, built and equipped to meet stringent anti-smog  
standards for the state of California and the federal government. Generac will warrant the emission control system on your  
engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modification or improper  
maintenance of your engine.  
Your emission control system may include parts such as the carburetor, ignition and exhaust systems. Generac will repair  
your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.  
MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:  
Emissions control systems on 1997 and later model year engines are warranted for two years as hereinafter noted. If, dur-  
ing such warranty period, any emission-related component or system on your engine is found to be defective in materials or  
workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.  
PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:  
As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory  
supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance  
on your engine. However, Generac cannot deny warranty solely because of the lack of receipts or for your failure to ensure  
the completion of all scheduled maintenance.  
As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or  
responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper maintenance or unap-  
proved modifications, or the use of counterfeit and/or ‘grey market’ parts not made, supplied or approved by Generac.  
You are responsible for presenting your engine to a Generac Authorized Warranty Service Facility as soon as a problem  
occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.  
Warranty service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Service Facility.  
To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:  
1-800-333-1322  
IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System  
Warranty (ECS Warranty), which is provided to you by Generac pursuant to California and federal law. See also the “Generac  
Limited Warranties for Generac Power Systems, Inc.,” which is enclosed herewith on a separate sheet, also provided to you  
by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in  
terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where  
the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Warranty describe  
important rights and obligations with respect to your new engine.  
Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty ser-  
vice, evidence must be presented showing the date of the sale to the original purchaser/owner. The purchaser/owner shall  
be responsible for any expenses or other charges incurred for service calls and/or transportation of the product to/from the  
inspection or repair facilities. The purchaser/owner also shall be responsible for any and/or all damages or losses incurred  
while the engine is being transported/shipped for inspection or warranty repairs.  
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the fol-  
lowing address:

Section 8 – Warranty  
Recreational Vehicle Generator  
EMISSION CONTROL SYSTEM WARRANTY  
Emission Control System Warranty (ECS Warranty) for 1997 and later model year engines:  
(a) Applicability: This warranty shall apply to 1997 and later model year engines. The ECS Warranty Period shall begin on  
the date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue  
for 24 consecutive months thereafter.  
(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or  
equipment, and to each subsequent purchaser/owner, that each of its engines is ...  
(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the EPA and CARB pursuant  
to their respective authority, and  
(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a  
warranted emissions-related part to fail to be identical in all material respects to the part as described in the engine  
manufacturer’s application for certification.  
(c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows:  
(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner’s  
Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall  
be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS  
Warranty shall be warranted for the remainder of the ECS Warranty Period.  
(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s Manual  
shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace  
as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty  
shall be warranted for the remainder of the ECS Warranty Period.  
(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s  
Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part  
fails prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection  
(4) below. Any such emissions-related part repaired or replaced under the ECS Warranty shall be warranted for the  
remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-related part.  
(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no  
charge to the owner at a Generac Authorized Warranty Service Facility.  
(5) When the engine is inspected by a Generac Authorized Warranty Service Facility, the owner shall not be held responsible  
for diagnostic costs if the repair is deemed warrantable.  
(6) Generac shall be liable for damages to other original engine components or approved modifications proximately caused  
by a failure under warranty of any emission-related part covered by the ECS Warranty.  
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient  
to meet the expected demand for such emission-related parts.  
(8) Any Generac authorized and approved emission-related replacement part may be used in the performance of any ECS  
Warranty maintenance or repairs and will be provided without charge to the purchaser/owner. Such use shall not reduce  
Generac’s ECS Warranty obligations.  
(9) Unapproved, add-on, modified, counterfeit and/or ‘grey market’ parts may not be used to modify or repair a Generac  
engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim.  
Generac shall not be held liable hereunder for failures of any warranted parts of a Generac engine caused by the use of  
such an unapproved, add-on, modified, counterfeit and/or ‘grey market’ part.

• Failures caused by any contaminated fuels, oils, coolants or lack of proper fluid amounts.  
• Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As with all  
mechanical devices, the Generac engines need periodic part(s) service and replacement to perform well. This warranty will not  
cover repair when normal use has exhausted the life of a part(s) or engine.  
• Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire,  
freezing, lightning, earthquake, windstorm, hail, volcanic eruption, water or flood, tornado or hurricane.  
• Damage related to rodent and/or insect infestation.

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES NO  
OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not allow  
limitations on how long an implied warranty lasts, so the above limitation may not apply to you.  
GENERAC'S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT SHALL  
GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A DIRECT  
RESULT OF GENERAC'S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential damages,  
so the above limitation may not apply to you.  
This warranty gives you specific legal rights. You also have other rights from state to state.
