IMPORTANT SAFETY INSTRUCTIONS
Air-cooled Generators
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 opera-
tors and potential operators of this equipment.
• WARNING:
GENERAL HAZARDS
• The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
• For safety reasons, the manufacturer recommends
that the installation, initial start-up and main-
tenance of this equipment is carried out by an
Authorized 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.
• 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.
• 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.
• Adequate, unobstructed flow of cooling and venti-
lating air is critical to correct generator operation.
Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seri-
ously affect safe operation of the generator. The
generator MUST be installed outdoors.
• 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 Dealer for parts needing repair
or replacement.
DANGER
Despite the safe design of this generator,
• 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, then remove the POSITIVE, POS or (+)
cable. When reconnecting the cables, connect the
POSITIVE cable first, the NEGATIVE 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.
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.
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.

IMPORTANT SAFETY INSTRUCTIONS
Air-cooled Generators
• Keep a fire extinguisher near the generator at all
times. Extinguishers rated “ABC” by the National
Fire Protection Association are appropriate for
use on the standby electric system. Keep the extin-
guisher properly charged and be familiar with its
use. Consult the local fire department with any
questions pertaining to fire extinguishers.
ELECTRICAL HAZARDS
• All generators covered by this manual produce
dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch
as does the standby generator when it is in opera-
tion. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure
all appropriate covers, guards and barriers are in
place, secured and/or locked before operating the
generator. If work must be done around an oper-
ating unit, stand on an insulated, dry surface to
reduce shock hazard.
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.
• Gaseous fluids such as natural gas and liquid pro-
pane (LP) gas are extremely EXPLOSIVE. Install
the fuel supply system according to applicable
fuel-gas codes. Before placing the home standby
electric system into service, fuel system lines must
be properly purged and leak tested according to
applicable code. After installation, inspect the fuel
system periodically for leaks. No leakage is permit-
ted.
• 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.
• The National Electrical Code (NEC) requires the
frame and external electrically conductive parts of
the generator to be connected to an approved earth
ground. Local electrical codes also may require
proper grounding of the generator electrical system.
• After installing this home standby electrical sys-
tem, the generator may crank and start at any
time without warning. When this occurs, load cir-
cuits are transferred to the STANDBY (generator)
power source. To prevent possible injury if such a
start and transfer occur, always set the generator’s
AUTO/OFF/MANUAL switch to its OFF position
before working on equipment and remove the 15A
fuse from the generator control panel.
• 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 implement,
such as a dry rope or board, to free the victim from
the live conductor. If the victim is unconscious,
apply first aid and get immediate medical help.
• 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.

There are LED readouts on the control panel to notify
personnel that one of these faults has occurred.
There is also a System Set LED that is lit when all
of the conditions described in section "System Set
LED" are true. (See the "Protection Systems" section
for details.)
DANGER
Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and regu-
lations.
1.3 NEC REQUIREMENT FOR ARC
FAULT CIRCUIT INTERRUPTION
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for
damage.
BREAKER FOR BEDROOMS
In 2001, the National Electric Code (NEC) intro-
duced a requirement for new construction. This new
requirement indicates the need for Arc Fault Circuit
Interrupters to be used to protect the complete
branch circuit that feeds a dwelling bedroom. The
actual NEC requirement is indicated below.
• This standby generator set is ready for installa-
tion with a factory supplied and pre-mounted base
pad and has a weather protective enclosure that is
intended for outdoor installation only.
• This UL listed standby generator set is packaged
with an automatic transfer switch with built in
load center. The combination transfer switch and
load center is pre-wired with a two foot and 30 foot
conduit. Circuit breakers for emergency circuit
connections are included (if equipped).
‹
1.3.1 SECTION 210.12 ARC FAULT CIRCUIT
INTERRUPTER PROTECTION
1. Definition: An arc fault circuit interrupter is a
device intended to provide protection from the
effects of arc faults by recognizing characteristics
unique to arcing and by functioning to de-ener-
gize the circuit when an arc fault is detected.
2. Dwelling Unit Bedrooms: All branch circuits that
supply 125 volt, single-phase, 15 and 20 ampere
outlets installed in dwelling unit bedrooms shall
be protected by an arc fault circuit interrupter
listed to provide protection of the entire branch
circuit.
Section 210.12 requires that AFCI protection be
provided on branch circuits that supply outlets
(receptacle, lighting, etc.) in dwelling bedrooms. The
requirement is limited to 15 and 20 ampere, 125
volt circuits. There is no prohibition against provid-
ing AFCI protection on other circuits or in locations
other than bedrooms. Because circuits are often
shared between a bedroom and other areas such as
closets and hallways, providing AFCI protection on
the complete circuit would comply with 210.12.
• This UL listed, 2-pole switch is rated at 100 AC
amperes at 250 volts maximum. This transfer
switch is for indoor use only (if equipped).
If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a transfer
switch. The transfer switch must effectively isolate
the electrical system from the utility distribution
system when the generator is operating (NEC 700,
701 & 702). Failure to isolate an electrical system
by such means will result in damage to the gen-
erator and also may result in injury or death to
utility power workers due to backfeed of electrical
energy.
If any loss or damage is noted at time of delivery, have
the person(s) making the delivery note all damage
on the freight bill or affix their signature under the
consignor's memo of loss or damage.
If during the installation of the home standby system
the decision is made to provide back up power to a
bedroom branch circuit, then the circuit breaker in
the transfer switch should be replaced with an Arc
Fault Circuit Interrupter.
If a loss or damage is noted after delivery, separate
the damaged materials and contact the carrier for
claim procedures.
“Concealed damage” is understood to mean damage
to the contents of a package that is not in evidence at
the time of delivery, but is discovered later.
It is most important that breakers only be switched
like for like. For instance, if replacing a 15A breaker,
it MUST be replaced with a 15A AFCI breaker.
Likewise, a 20A breaker MUST be replaced with a
20A AFCI.
1.2 PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have
to run for long periods of time with no operator pres-
ent to monitor engine conditions. For that reason, the
engine is equipped with the following systems that
protect it against potentially damaging conditions:
These AFCI breakers are available at the nearest
hardware store.

Section 1 — General Information
Air-cooled Generators
Special considerations should be given when install-
ing the unit where local conditions include flooding,
tornados, hurricanes, earthquakes and unstable
ground for the flexibility and strength of piping and
their connections.
1.6 SYSTEM SET LED
The “System Set” LED is lit when all of the following
conditions are true:
1. The AUTO/OFF/MANUAL switch is set to the
AUTO position.
Use an approved pipe sealant or joint compound on
all threaded fitting.
2. The utility voltage being supplied to the unit is
being sensed by the PCB. If the utility sense volt-
age is not connected to the unit or if it is below
approximately 150-160 volts AC, then the system
set light will flash rapidly. This indicates that if
the AUTO/OFF/ MANUAL switch is placed in the
Auto position, the generator will start.
All installed gaseous fuel piping must be purged and
leak tested prior to initial start-up in accordance with
local codes, standards and regulations.

1.7 FUEL REQUIREMENTS
AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal sys-
tem. This type of system uses the vapors formed
above the liquid fuel in the storage tank.
*Natural gas is in cubic feet per hour.
**LP is in gallons per hour/cubic feet per hour.
*** Values given are approximate.
The engine has been fitted with a fuel carburetion
system that meets the specifications of the 1997
California Air Resources Board for tamper-proof dual
fuel systems. The unit will run on natural gas or LP
gas, but it has been factory set to run on natural gas.
Should the primary fuel need to be changed to LP
gas, the fuel system needs to be reconfigured. See the
Reconfiguring the Fuel System section for instruc-
tions on reconfiguration of the fuel system.
‹
1.8.1 BTU FLOW REQUIREMENTS -
NATURAL GAS
BTU flow required for each unit based on 1000 BTU
per cubic foot.
• 6kW — 119,000 BTU/Hour
• 9kW — 156,000 BTU/Hour
• 13kW — 220,000 BTU/Hour
• 15kW — 245,000 BTU/Hour
Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas; or at
least 2,520 Btus per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
DANGER
Gaseous fuels such as natural gas and liquid
propane (LP) gas are highly explosive. Even the
slightest spark can ignite such fuels and cause
an explosion. No leakage of fuel is permitted.
Natural gas, which is lighter than air, tends to
collect in high areas. LP gas is heavier than air
and tends to settle in low areas.
Required fuel pressure for natural gas is 5 inches
to 7 inches water column (0.18 to 0.25 psi); and
for liquid propane, 10 inches to 12 inches of water
column (0.36 to 0.43 psi).
NOTE:
All pipe sizing, construction and layout must com-
ply with NFPA 54 for natural gas applications and
NFPA 58 for liquid propane applications. Once the
generator is installed, verify that the fuel pressure
NEVER drops below four (4) inches water column
for natural gas or 10 inches water column for liq-
uid propane.
NOTE:
A minimum of one approved manual shut-off valve
must be installed in the gaseous fuel supply line.
The valve must be easily accessible. Local codes
determine the proper location.
Prior to installation of the generator, the installer
should consult local fuel suppliers or the fire mar-
shall to check codes and regulations for proper
installation. Local codes will mandate correct routing
of gaseous fuel line piping around gardens, shrubs
and other landscaping to prevent any damage.

Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive.
The following procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush thor-
oughly and immediately with water and seek
medical attention; and
• 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) of 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.
NOTE:
In areas where temperatures regularly fall below
10° F (-12° C) it is recommended that a pad type
battery heater be installed to aid in cold climate
starting (see Specifications).
NOTE:
Lead-acid batteries present a risk of fire because
they generate hydrogen gas. The following
The generator is equipped with a battery trickle
charger that is active when the unit is set up for
automatic operation. With the battery installed
and utility power source voltage available to the
transfer switch, the battery receives a trickle
charge while the engine is not running, to prevent
self-discharge. The trickle charger is designed to
help extend the life of the battery by maintain-
ing the battery when the unit is not running. The
trickle charge feature cannot be used to recharge
a discharged battery.
procedures are to be followed:
• DO NOT SMOKE when near the battery;
• DO NOT cause flame or spark in battery area; and
• Discharge static electricity from body before touch-
ing the battery by first touching a grounded metal
surface.
Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as the
battery cables are connected.
1.13 THE BATTERY
DANGER
Be sure the utility power supply is turned off
and the 15A fuse is removed from the generator
control panel, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
Do not dispose of the battery in a fire. The
battery is capable of exploding.
Servicing of the battery is to be performed or super-
vised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized person-
nel away from batteries.
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:
See the Specifications section for the correct size
and rating when replacing the battery. When using a
maintenance-free battery, it is not necessary to check
the specific gravity or electrolyte level. Have these
procedures performed at the intervals specified in
the “Service Schedule.” A negative ground system is
used. Battery connections are shown on the wiring
diagrams. Make sure the battery is correctly connect-
ed and terminals are tight. Observe battery polarity
when connecting the battery to the generator set.
• Remove the 15A fuse from the generator control
panel.
• 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

Air-cooled Generators
A. Utility Voltage Dropout Sensor
‹
3.1.4 CHOKE OPERATION
• This sensor monitors utility source voltage.
• If utility source voltage drops below about 65
percent of the nominal supply voltage, the sensor
energizes a 10 second timer.
• Once the timer has expired, the engine will crank
and start if utility is still low.
1. 990 engines have an electric choke in the air box
that is automatically controlled by the electronic
control board.
2. 530 engines have an electric choke on the divider
panel air inlet hose that is automatically con-
trolled by the electronic control board.
3. 410 engines do not have a choke.
B. Engine Warm-up Time Delay
• This mechanism lets the engine warm up for
about five (5) seconds before the load is trans-
ferred to the standby source.
3.2 AUTOMATIC TRANSFER
C. Standby Voltage Sensor
OPERATION
To select automatic operation, do the following:
• This sensor monitors generator AC output volt-
age. When the voltage has reached 50 percent of
the nominal rated voltage, transfer to standby
can occur.
1. Make sure the transfer switch main contacts are
set to their UTILITY position, i.e., loads con-
nected to the utility power source (Figure 3.2).
2. Be sure that normal UTILITY power source volt-
age is available to transfer switch terminal lugs
N1 and N2 (Refer to the Electrical Data section).
3. Set the generator’s AUTO/OFF/MANUAL switch to
AUTO.
D. Utility Voltage Pickup Sensor
• This sensor monitors utility power supply volt-
age. When that voltage is restored above 75 per-
cent of the nominal source voltage, a retransfer
time delay starts timing.
E. Retransfer Time Delay
4. Set the generator’s main circuit breaker to its ON
• This timer runs for about 15 seconds.
• At end of a 15-second delay, circuit board action
de-energizes transfer relay in the transfer switch

With the preceding steps complete, the generator will
start automatically when utility source voltage drops
below a preset level. After the unit starts, loads are
transferred to the standby power source. Refer to the
Sequence of Automatic Operation section.
3.3 SEQUENCE OF AUTOMATIC
• The timer will run for about one minute, and the
generator will then shut down.
OPERATION
The generator’s control panel houses a control logic
circuit board. This board constantly monitors util-
ity power source voltage. Should that voltage drop
below a preset level, circuit board action will signal
the engine to crank and start. After the engine starts,
the circuit board signals the transfer switch to acti-
vate and connect load circuits to the standby power
supply (load terminal lugs T1/T2 connect to terminal
lugs E1/E2). Refer to the Electrical Data section.

minutes.
7. Set the system to automatic operation as outlined
in Automatic Transfer Operation section.
7. Set the generator’s main circuit breaker to its ON
(or CLOSED) position. The standby power source
now powers the loads.
3.5 SETTING THE EXERCISE TIMER
This generator is equipped with an exercise timer.
Once it is set, the generator will start and exercise
once every seven days, on the day of the week and at
the time of day the following sequence is completed.
During this exercise period, the unit runs for approx-
imately 12 minutes and then shuts down. Transfer of
loads to the generator output does not occur during
the exercise cycle unless utility power is lost.
Figure 3.2 – Manual Transfer Switch Operation
A switch on the control panel (see Figure 3.1) per-
mits selection of the day and time for the system to
exercise. At the chosen time, perform the following
sequence to select the desired day and time of day
the system will exercise. Remember seasonal time
changes affect the exercise time settings.
1. Verify that the AUTO/OFF/MANUAL switch is set
to AUTO.
2. Press and hold the "Set Exercise Time" switch for
several seconds, then release. All the red LED's
will flash for approximately 10 seconds and then
stop.
3. Once the red LED's stop flashing, the generator
will start and run for approximately 12 minutes
and then shut down. The exerciser is now set to
run at this time of day each week.
‹
3.4.2 TRANSFER BACK TO UTILITY POWER
SOURCE
Example: If the "Set Exercise Time" switch is
pressed on Saturday afternoon at 2:00 p.m., the
generator will start and exercise for approximate-
ly 12 minutes every Saturday at 2:00 p.m..
NOTE:
When utility power has been restored, transfer back
to that source and shut down the generator. This can
be accomplished as follows:
1. Set the generator’s main circuit breaker to its
OFF (or OPEN) position.
2. Let the engine run for a minute or two at no-load
to stabilize the internal temperatures.
3. Set the generator’s AUTO/OFF/MANUAL switch to
its OFF (or OPEN) position. The engine should
shut down.
The exerciser will only work in the AUTO mode
and will not work unless this procedure is per-
formed. The exerciser will need to be reset every
time the 12-volt battery is disconnected and then
reconnected, and when the 15A fuse is removed.
The 16kW unit has a low speed exercise option. Dip
switch 1 on the control board is factory set to OFF.
This allows the engine to run at a slower speed dur-
ing weekly exercise periods for quieter operation. If
this Dip switch is set to ON, the generator will exer-
cise at it's normal speed.
4. Check that utility power supply to the transfer
switch is turned OFF.
DANGER
Do not attempt to activate the transfer switch
manually until all power voltage supplies
to the switch have been positively turned off.
Failure to turn off all power voltage supplies
may result in extremely hazardous and possibly
fatal electrical shock.
This DIP switch position is only read at board power
up. If the DIP switch position is changed, power to
the board must be cycled for the micro controller to
recognize the new DIP switch position.

Section 3 — Operation
Air-cooled Generators
Low speed exercise will be handled as follows:
‹
3.6.3 OVERCRANK
1. The standard start sequence will be initiated.
2. The unit will run at 2,400 RPM.
This feature prevents the generator from damaging
itself when it continually attempts to start and anoth-
er problem, such as no fuel supply, prevents it from
starting. The unit will crank and rest for a preset
time limit. Then, it will stop cranking, and the LED
on the generator control panel will light indicating an
overcrank failure. The AUTO/OFF/MANUAL switch
will need to be set to OFF and then back to AUTO to
reset the generator control board.
3. If utility is lost during exercise, the controller will
do the following:
• Wait 10 seconds for utility to return.
• If utility returns within 10 seconds, continue to
exercise at 2,400 RPM.
• If utility is still lost after 10 seconds, run the
engine up to 3600 RPM and transfer the load.
At this time the controller will exit the exercise
routine and assume full automatic operation.
NOTE:
If the fault is not repaired, the overcrank feature
will continue to activate.

3.6.5 RPM SENSOR FAILURE
4.2 CHECKING THE ENGINE
During cranking, if the board does not see a valid
RPM signal within three (3) seconds, it will shut
down and latch out on RPM sensor loss.
OIL LEVEL
For oil capacities, see the Specifications section.
For engine oil recommendations, see the Engine Oil
Recommendations section. To check the engine oil
level, proceed as follows (Figures 4.2, 4.3 and 4.4):
During running, if the RPM signal is lost for one full
second the board will shut down the engine, wait 15
seconds, then re-crank the engine.
1. Move the AUTO/OFF/ MANUAL switch to the OFF
position.
• If an RPM signal is not detected within the first
three (3) seconds of cranking, the control board
will shut the engine down and latch out on RPM
sensor loss.
• If the RPM signal is detected the engine will start
and run normally. If the RPM signal is subsequent-
ly lost again, the control board will try one more
re-crank attempt before latching out and flashing
the overspeed LED.
2. Remove the dipstick and wipe it dry with a clean
cloth.
3. Completely insert the dipstick; then, remove it
again. The oil level should be at the dipstick “Full”
mark. If necessary, add oil to the “Full” mark
only. DO NOT FILL ABOVE THE “FULL” MARK.
Never operate the engine with the oil level
this could damage the engine.
4. Install the dipstick.

The microprocessor will continually monitor the
battery voltage and turn on the Low Battery LED if
the battery voltage falls below 11.0 volts for one (1)
minute. No other action is taken on a low battery
condition. Low battery voltage is a non-latching alarm
which will automatically clear if the battery voltage
rises above 11.0 volts. Battery voltage is NOT moni-
tored during the crank cycle.
5. Reset the AUTO/OFF/MANUAL switch to its origi-
nal position.

4.1 FUSES
The 15-amp fuse on the generator panel protects the
DC control circuit against overload (Figure 4.1). This
fuse is wired in series with the battery output lead
to the panel. If this fuse element has melted open,
the engine will not be able to crank or start. Replace
this fuse using only an identical 15-amp replacement
fuse. To replace the fuse, push the fuse holder cap
down and rotate it counterclockwise. Whenever the
fuse is removed or replaced, the exercise timer needs
to be reset.

3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.76 mm (0.030 inch) for
7 and 10kW; and 1.02 mm (0.040 inch) for 13/16
kW by carefully bending the ground electrode
(Figure 4.9).
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
Figure 4.9 – Setting the Spark Plug Gap
• Where electrolyte contacts the eyes, flush
thoroughly and immediately with water and seek
medical attention; and
SET PLUG GAP AT 0.76 mm (.030 inch) - 7 & 10kW;
1.02 mm (.040 inch) - 13 & 16kW
• 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) of 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.
Lead-acid batteries present a risk of fire because
they generate hydrogen gas. The
4.6 BATTERY MAINTENANCE
The battery should be inspected per the "Service
Schedule" section. The following procedure should be
followed for inspection:
following procedures are to be followed:
• DO NOT SMOKE when near the battery;
• DO NOT cause flame or spark in battery area; and
• Discharge static electricity from body before touch-
ing the battery by first touching a grounded metal
surface.
1. Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as the
battery cables are connected.
3. Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
Be sure the utility power supply is turned off
DANGER
and the 15A fuse is removed from the generator
control panel, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
Do not dispose of the battery in a fire. The
battery is capable of exploding.
A battery presents a risk of electrical shock
and high short circuit current. The following pre-
4.7 ADJUSTING GH-410/GT-530/990
cautions are to be observed when working on
batteries:
VALVE CLEARANCE
• Remove the 15A fuse from the generator control
panel.
• 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; and
After the first six (6) months of operation, check
the valve clearance in the engine, adjust if neces-
sary.
Important: If feeling uncomfortable about doing
this procedure or the proper tools are not available,
please contact the Authorized Dealer for service
assistance. This is a very important step to insure
longest life for the engine.
• Disconnect charging source prior to connecting or
disconnecting battery terminals.
To check valve clearance:
• The engine should be cool before checking. If
valve clearance is 0.002" - 0.004" (0.05 - 0.1mm),
adjustment is not needed.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.

Section 4 — Maintenance
Air-cooled Generators
• Remove spark plug wires and position wires away
from plugs.
• Remove spark plugs.
• Install spark plugs.
• Re-attach the spark plug wire to the spark plug.
• On the GT-530 and GT-990, repeat the process for
the other cylinder.
• Make sure the piston is at Top Dead Center (TDC)
of its compression stroke (both valves closed). To
get the piston at TDC, remove the intake screen at
the front of the engine to gain access to the flywheel
nut. Use a large socket and socket wrench to rotate
the nut and hence the engine in a clockwise direc-
tion. While watching the piston through the spark
plug hole. The piston should move up and down.
The piston is at TDC when it is at its highest point
of travel.
4.8 COOLING SYSTEM
Air inlet and outlet openings in the generator com-
partment must be open and unobstructed for con-
tinued proper operation. This includes such obstruc-
tions as high grass, weeds, brush, leaves and snow.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it
to quickly shut down. (See Figure 4.11 for vent loca-
tions.)
To adjust valve clearance (if necessary):
• Make sure the engine is at 60° to 80° F.
• Make sure that the spark plug wire is removed
from the spark plug and out of the way.
• Remove the four screws attaching the valve cover
with a #2 or #3 Phillips screwdriver.
Make sure the doors and roof are in place dur-
ing operation as running the generator with them
removed can effect cooling air movement.
Figure 4.11 – Cooling Vent Locations
• Loosen the rocker jam nut. Use an 10mm allen
wrench to turn the pivot ball stud while checking
clearance between the rocker arm and the valve
stem with a feeler gauge. Correct clearance is
0.002-0.004 inch (0.05-0.1 mm).
NOTE:
Hold the rocker arm jam nut in place as the pivot
ball stud is turned.
When valve clearance is correct, hold the pivot ball
stud in place with the allen wrench and tighten the
rocker arm jam nut. Tighten the jam nut to 174
in/lbs. torque. After tightening the jam nut, recheck
valve clearance to make sure it did not change.

The maximum ambient temperature for the gen-
erator is 40° C (104° F).
4.9 ATTENTION AFTER SUBMERSION
If the generator has been submerged in water, it must
not be started and operated. Following any submer-
sion in water, have an Authorized Dealer thoroughly
clean, dry and inspect the generator. If the structure
(ex. home) has been flooded, it should be inspected
by a certified electrician to ensure there won't be any
electrical problems during generator operation or
when utility is returned.
• Install new valve cover gasket.
• Re-attach the valve cover.
NOTE:
Start all four screws before tightening or it will not
be possible to get all the screws in place. Make
sure the valve cover gasket is in place.

Section 10 – Warranty
Air-cooled Generators
NOTE: This Emission Control Warranty Statement pertains to this product only IF the generator size is 15 kW or below.
CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board (CARB) and Generac Power Systems, Inc. (Generac) are pleased to explain the Emission
Control System Warranty on your new engine.* In California, new utility, and lawn and garden equipment engines must be
designed, built and equipped to meet the state’s stringent anti-smog standards. 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 modifica-
tion or improper maintenance of your engine.
Your emission control system may include parts such as the carburetor, ignition system and exhaust system. 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 1995 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 due to 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 contacting 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 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.
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at one of
the following addresses:

Section 10 – Warranty
Air-cooled Generators
EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty (ECS Warranty) for 1995 and later model year engines:
(a) Applicability: This warranty shall apply to 1995 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 CARB pursuant to its
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 owner. Such use shall not reduce Generac
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.
EMISSION RELATED PARTS INCLUDE THE FOLLOWING:

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES

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.
