INTRODUCTION  
Thank you for purchasing this model of the GUARDIAN® product  
line by Generac Power Systems, Inc. This model is a compact,  
high performance, air-cooled, engine driven generator designed  
to supply electrical power to operate electrical loads when utility  
power is unavailable due to a power outage.  
CAUTION! Always disconnect spark plug wire and place the  
wire where it cannot contact the spark plug to prevent accidental  
starting when setting up, transporting, adjusting or making  
repairs to your generator.

2.3.2 CONNECTING ELECTRICAL LOADS  
2.3 HOW TO USE THE GENERATOR  
If you have any problems operating your generator, please call the  
generator helpline at 1-800-333-1322.  
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO  
NOT connect 3-phase loads to the generator. DO NOT connect  
50 Hz loads to the generator.  
• Let engine stabilize and warm up for a few minutes after  
starting.  
2.3.1 GROUNDING THE GENERATOR  
The National Electrical Code requires that the frame  
and external electrically conductive parts of this  
generator be properly connected to an approved earth  
ground. Local electrical codes may also require proper  
grounding of the unit. For that purpose, generally, connecting a  
No. 10 AWG (American Wire Gauge) stranded copper wire to the  
grounding wing nut and to an earth-driven copper or brass  
grounding rod (electrode) provides adequate protection against  
electrical shock. However, local codes may vary widely. Consult  
with a local electrician for grounding requirements in  
your area.  
• Plug in and turn on the desired 120 or 240 Volt AC, single  
phase, 60 Hz electrical loads.  
• Add up the rated watts (or amps) of all loads to be connected  
at one time. This total should not be greater than (a) the rated  
wattage/amperage capacity of the generator or (b) circuit  
breaker rating of the receptacle supplying the power. See  
"Don't Overload the Generator" below.  
2.4 DON’T OVERLOAD THE  
GENERATOR  
Overloading a generator in excess of its rated wattage capacity  
can result in damage to the generator and to connected electrical  
devices. Observe the following to prevent overloading the unit:  
Figure 13 - Grounding the Generator  
• Add up the total wattage of all electrical devices to be  
connected at one time. This total should NOT be greater than  
the generator's wattage capacity.  
Generator Ground Lug  
• The rated wattage of lights can be taken from light bulbs. The  
rated wattage of tools, appliances and motors can usually be  
found on a data plate or decal affixed to the device.  
• If the appliance, tool or motor does not give wattage, multiply  
volts times ampere rating to determine watts (volts x amps =  
watts).  
• Some electric motors, such as induction types, require about  
three times more watts of power for starting than for running.  
This surge of power lasts only a few seconds when starting  
such motors. Make sure you allow for this high starting  
wattage when selecting electrical devices to connect to your  
generator:  
Proper grounding of the generator will help prevent  
electrical shock in the event of a ground fault condition in the  
generator or in connected electrical devices. Proper grounding  
also helps dissipate static electricity, which often builds up in  
ungrounded devices.  
1. Figure the watts needed to start the largest motor.  
2. Add to that figure the running watts of all other connected  
loads.  
The Wattage Reference Guide on page 10 is provided to assist  
you in determining how many items your generator can operate  
at one time. (Note: All figures are approximate. See data plate on  
appliance for wattage requirements.)

*Allow 3 times the listed watts for starting these devices.  
Above 40°F, use SAE 10W-30 or SAE 30.  
Below 40°F, use synthetic 5W-20 or 5W-30.  
2.6 BEFORE STARTING THE  
GENERATOR  
Although multi-viscosity oils (5W-30, 10W-30, etc.) improve  
starting in cold weather, these multi-viscosity oils will result in  
increased oil consumption when used above 32°F. Check your  
engine oil level more frequently to avoid possible damage from  
running low on oil.  
Prior to operating the generator, engine oil and gasoline will need  
to be added, as follows:  
2.6.1 ADDING ENGINE OIL  
• Place generator on a level surface.  
NOTE: When adding oil to the engine crankcase in  
the future, use only high quality detergent oil rated  
with API service classification SF or SG SAE 30  
weight. Use no special additives.  
• Clean area around oil fill and remove oil fill cap and dipstick.  
Wipe dipstick clean.  
Slowly fill engine with oil through the oil fill opening until it  
reaches the full mark on the dipstick. Stop filling occasionally  
to check oil level. DO NOT OVERFILL.  
Select the oil’s viscosity grade according to the expected  
operating temperature. Do not use SAE 10W-40.  
• Install dipstick. Install oil fill cap and finger tighten securely.  
• Check engine oil level before starting each time thereafter.

2.6.2 ADDING GASOLINE  
-------------  
-------------  
ƽ WARNING ƽ  
Ʒ WARNING: Never fill fuel tank indoors. Never fill  
fuel tank when engine is running or hot. DO NOT  
light a cigarette or smoke when filling the fuel  
tank.  
ƽ Caution: Do not overfill the fuel tank. Always  
leave room for fuel expansion.  
• Use regular UNLEADED gasoline with the generator engine. Do  
not use premium gasoline. Do not mix oil with gasoline.  
• Clean area around fuel fill cap, remove cap.  
• Slowly add unleaded regular gasoline to fuel tank. Be careful  
not to overfill. Allow about 1/2" of tank space for fuel  
expansion, as shown here.  
• Locate the Idle Control ON/OFF switch on the control panel and  
set it to the “OFF” position.  
Install fuel cap and wipe up any spilled gasoline.  
Figure 16 - Idle Control Switch  
Figure 14 - Fuel Tank  
IMPORTANT: It is important to prevent gum deposits from  
forming in fuel system parts such as the carburetor, fuel hose or  
tank during storage. Alcohol-blended fuels (called gasohol,  
ethanol or methanol) can attract moisture, which leads to  
separation and formation of acids during storage. Acidic gas can  
damage the fuel system of an engine while in storage. To avoid  
engine problems, the fuel system should be emptied before  
storage of 30 days or longer. See "Storage" on page 18. Never use  
engine or carburetor cleaner products in the fuel tank as  
permanent damage may occur.  
2.7 TO START THE ENGINE  
WARNING! Never start or stop engine with electrical  
devices plugged into the receptacles AND devices turned on.  
• Unplug all electrical loads from the unit's receptacles before  
starting the engine.  
• Make sure the unit is in a level position.  
• Open the fuel shut-off valve.

Section 2 – Operation  
Residential Portable Generator System  
• Move engine CHOKE knob to “Full Choke” position.  
2.9 AUTOMATIC IDLE CONTROL  
Figure 17 - Full Choke Position  
This feature is designed to greatly improve fuel economy. When  
this switch is turned On,” the engine will only run at its normal  
fast governed engine speed when electrical load is connected.  
When the load is removed, the engine will run at a reduced speed  
of 2100 RPM. With the switch Off,” the engine runs at the  
normal fast engine speed all the time. Always have the switch  
OFF when starting and stopping the engine.  
2.10 COLD WEATHER OPERATION/  
DE-ICER  
Under certain weather conditions (temperatures below 40° F (4°  
C) and a high dew point), the engine may experience icing of the  
carburetor and/or the crankcase breather system. To eliminate  
this problem, this generator engine is fitted with a winter/summer  
valve. this directs hot air into the carburetor during cold weather  
operation. Always make sure the winter/summer valve is in the  
correct location relative to the weather conditions.  
• To start engine, press and hold the Start/Run/Stop switch in  
the “Start” position. The engine will crank and attempt to start.  
When the engine starts, release the switch to the run position.  
• When the engine starts, move choke knob to “1/2 Choke” position until  
the engine runs smoothly and then to “Run” position. If engine falters,  
move choke knob to “1/2 Choke” position until the engine runs  
smoothly and then to “Run” position.  
2.11 LOW OIL PRESSURE SHUTDOWN  
SYSTEM  
The engine is equipped with a low oil pressure sensor that shuts  
down the engine automatically when the oil pressure drops below  
10 psi. If the engine shuts down by itself and the fuel tank has  
enough gasoline, check engine oil level.  
Note: If engine fires, but does not continue to run,  
move choke lever to “Full Choke” and repeat starting  
instructions.  
2.8 STOPPING THE ENGINE  
• Shut off all loads, then unplug the electrical loads from  
generator panel receptacles. Never start or stop the engine  
with electrical devices plugged in and turned on.  
2.11.1 INITIAL START-UP  
A delay built into the low oil shutdown system allows oil pressure  
to build during starting. The delay allows the engine to run for  
about 10 seconds before sensing oil pressure.  
• Turn “Off” the Idle Control switch (if on).  
• Let engine run at no-load for several minutes to stabilize the  
internal temperatures of engine and generator.  
2.11.2 SENSING LOW OIL PRESSURE  
• Move Start/Run/Stop switch to “Off” position.  
• Close fuel valve.  
If the system senses low oil pressure during operation, the engine  
shuts down.  
IMPORTANT: Do not overload the generator. Also, do not  
overload individual panel receptacles. These outlets are protected  
against overload with push-to-reset-type circuit breakers. If  
amperage rating of any circuit breaker is exceeded, that breaker  
opens and electrical output to that receptacle is lost. Read “Don’t  
Overload the Generator” on page 9 carefully.  
2.11.3 RESTARTING  
If you try to restart the engine within 10 seconds after it shuts  
down, the engine may NOT start. The system needs 5 to 10  
seconds to reset.  
If you do restart the engine after such a shutdown and have not  
corrected the low oil pressure, the engine runs for about 10  
seconds as described above and then stops.

2.12 CHARGING A BATTERY  
Ʒ DANGER! Storage batteries give off explosive hydrogen  
gas while recharging. An explosive mixture will remain  
around the battery for a long time after it has been charged.  
The slightest spark can ignite the hydrogen and cause an  
explosion. Such an explosion can shatter the battery and  
cause blindness or other serious injury.  
ƽ DANGER! Do not permit smoking, open flame, sparks or  
any other source of heat around a battery. Wear protective  
goggles, rubber apron and rubber gloves when working  
around a battery. Battery electrolyte fluid is an extremely  
caustic sulfuric acid solution that can cause severe burns. If  
spill occurs flush area with clear water immediately.  
Your generator has the capability of recharging a discharged 12  
Volt automotive or utility style storage battery. Do not use the  
unit to charge any 6 Volt batteries. Do not use the unit  
to crank an engine having a discharged battery.  
To recharge 12 Volt batteries, proceed as follows:  
• Check fluid level in all battery cells. If necessary, add ONLY  
distilled water to cover separators in battery cells. Do not use  
tap water.  
• If the battery is equipped with vent caps, make sure they are  
installed and are tight.  
• If necessary, clean battery terminals.  
• Connect battery charge cable connector plug to panel  
receptacle identified by the words "12-VOLT D.C."  
• Connect battery charge cable clamp with red handle to the  
positive (+) battery terminal.  
• Connect battery charge cable clamp with black handle to the  
negative (-) battery terminal.  
• Start engine. Let the engine run while battery recharges.  
Engine idle control switch must be in off position for battery  
charging.  
• When battery has charged, shut down engine.  
Note: Use an automotive hydrometer to test battery  
state of charge and condition. Follow the hydrometer  
manufacturer's instructions carefully. Generally, a  
battery is considered to be at 100% state of charge  
when specific gravity of its fluid (as measured by  
hydrometer) is 1.260 or higher.

3.3.3 ENGINE MAINTENANCE  
3.3 GENERAL RECOMMENDATIONS  
DANGER! When working on the generator, always disconnect  
negative cable from battery. Also disconnect spark plug wires  
from spark plug and keep wire away from spark plug.  
The warranty of the generator does not cover items that have  
been subjected to operator abuse or negligence. To receive full  
value from the warranty, the operator must maintain the  
generator as instructed in this manual.  
3.3.4 CHECKING OIL LEVEL  
See the “BEFORE STARTING THE GENERATOR” section on page  
10 for information on checking the oil level. The oil level should  
be checked before each use, or at least every eight hours of  
operation. Keep the oil level maintained.  
Some adjustments will need to be made periodically to properly  
maintain the generator.  
All adjustments in the Maintenance section (3) of this manual  
should be made at least once each season. Follow the  
requirements in the "Maintenance Schedule" chart on page 14.  
3.3.5 CHANGING THE OIL AND OIL FILTER  
Change the oil and filter after the first eight hours of operation.  
Change the oil every 100 hours thereafter. If you are running this  
unit under dirty or dusty conditions, or in extremely hot weather,  
change the oil more often.  
NOTE: Once a year you should replace the spark plug  
and replace the air filter. A new spark plug and clean  
air filter assure proper fuel-air mixture and help your  
engine run better and last longer.  
Use the following instructions to change the oil while  
the engine is still warm:  
3.3.1 GENERATOR MAINTENANCE  
Generator maintenance consists of keeping the unit clean and dry.  
Operate and store the unit in a clean dry environment where it will  
not be exposed to excessive dust, dirt, moisture or any corrosive  
vapors. Cooling air slots in the generator must not become  
clogged with snow, leaves, or any other foreign material.  
• Clean area around oil drain hose and plug.  
• Remove oil drain plug from end of hose and oil fill plug to drain  
oil completely into a suitable container.  
• When oil has completely drained, install oil drain plug and  
tighten securely.  
Check the cleanliness of the generator frequently and clean when  
dust, dirt, oil, moisture or other foreign substances are visible on  
its exterior surface.  
• Place a suitable container beneath the oil filter and turn filter  
counterclockwise to remove. Discard according to local  
regulations.  
• Coat gasket of new filter with clean engine oil. Turn filter  
clockwise until gasket contacts lightly with filter adapter. Then  
tighten an additional 3/4 turn.  
ƽCAUTION! Never insert any object or tool through the air  
cooling slots, even if the engine is not running.  
• Fill oil sump with recommended oil. (See “Before Starting the  
Generator” on page 10 for oil recommendations).  
Note: DO NOT use a garden hose to clean generator.  
Water can enter the engine fuel system and cause  
problems. In addition, if water enters the generator  
through cooling air slots, some water will be retained  
in voids and crevices of the rotor and stator winding  
insulation. Water and dirt buildup on the generator  
internal windings will eventually decrease the  
insulation resistance of these windings.  
• Wipe up any spilled oil.  
3.3.2 TO CLEAN THE GENERATOR  
• Use a damp cloth to wipe exterior surfaces clean.  
• A soft, bristle brush may be used to loosen caked on dirt, oil, etc.  
• A vacuum cleaner may be used to pick up loose dirt and debris.  
• Low pressure air (not to exceed 25 psi) may be used to blow  
away dirt. Inspect cooling air slots and openings on the  
generator. These openings must be kept clean and  
unobstructed.

2. Clean the area around the spark plug and remove it from the  
cylinder head.  
• Remove air cleaner cover; then remove foam pre-filter (service  
if necessary) and remove paper filter.  
3. Set the spark plug's gap to 0.76 mm (0.030 in.). Install the  
correctly gapped spark plug into the cylinder head.  
• Clean paper 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.  
Figure 18 - Spark Plug Gap  
• Clean air cleaner cover then slip pre-cleaner over filter. Next  
insert new paper filter into the base of the air cleaner. Re-  
install air cleaner cover.  
Note: To order a new air filter, please contact the  
nearest authorized service center at 1-800-333-1322.  
3.5 CLEAN SPARK ARRESTOR  
SCREEN  
The engine exhaust muffler has a spark arrestor screen. Inspect  
and clean the screen at least once each year. If unit is used  
regularly, inspect and clean more often.  
3.4 SERVICE AIR CLEANER  
NOTE: If you use your 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.  
Your engine will not run properly and may be damaged if you run  
it using a dirty air cleaner. Clean or replace the air cleaner paper  
filter once a year. Clean or replace more often if operating under  
dusty conditions. Clean foam pre-cleaner every month or more  
often under dusty conditions.  
Clean and inspect the spark arrestor as follows:  
• Remove the screen retaining bracket by removing the screw.  
• Slide the spark arrestor screen out from the tail pipe.

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.  
Figure 21 - Spark Arrestor  
Figure 22 - Valve Clearance Adjustment  
3.6 ADJUSTING VALVE CLEARANCE  
After the first 50 hours of operation, you should adjust  
the valve clearance in the engine.  
• Install new valve cover gasket.  
• Re-attach the valve cover.  
Important: If you feel uncomfortable about doing this procedure  
or you don't have the proper tools, please take your generator in  
to the nearest service center to have the valve clearance adjusted.  
This is a very important step to insure longest life for your engine.  
NOTE: Start all four screws before tightening or you  
will not be able to get all the screws in place. Make  
sure the valve cover gasket is in place.  
To adjust valve clearance:  
• Re-attach the spark plug wire to the spark plug.  
• Repeat the process for the other cylinder.  
• Make sure the engine is at room temperature.  
• 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 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. While watching  
the piston through the spark plug hole. The piston should  
move up and down. The piston is at TDC when it is up as high  
as it can go.  
• 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: You must hold the rocker arm jam nut in place  
as you turn the pivot ball stud.

3.7 GENERAL  
3.9 OTHER STORAGE TIPS:  
The generator should be started at least once every seven days  
and be allowed to run at least 30 minutes. If this cannot be done  
and you must store the unit for more than 30 days, use the  
following information as a guide to prepare it for storage.  
• Do not store gasoline from one season to another.  
• Replace your gasoline can if your can starts to rust. Rust  
and/or dirt in your gasoline will cause problems with the  
carburetor and fuel system.  
• If possible, store your unit indoors and cover it to give  
protection from dust and dirt. BE SURE TO EMPTY THE  
FUEL TANK.  
ƷƸDANGER! NEVER store engine with fuel in  
tank indoors or in enclosed, poorly ventilated  
areas where fumes may reach an open flame,  
spark or pilot light as on a furnace, water heater,  
clothes dryer or other gas appliance.  
• If it is not practical to empty the fuel tank and the unit is to be  
stored for some time, use a commercially available fuel  
stabilizer added to the gasoline to increase the life of the  
gasoline.  
3.8 LONG TERM STORAGE  
• Cover your unit with a suitable protective cover that does not  
retain moisture.  
It is important to prevent gum deposits from forming in essential  
fuel system parts such as the carburetor, fuel hose or tank during  
storage. Also, experience indicates that alcohol-blended fuels  
(called gasohol, ethanol or methanol) can attract moisture, which  
leads to separation and formation of acids during storage. Acidic  
gas can damage the fuel system of an engine while in  
storage.  
ƽ DANGER! NEVER cover your generator while  
engine and exhaust area are warm.  
To avoid engine problems, the fuel system should be emptied  
before storage of 30 days or longer, as follows:  
• Remove all gasoline from the fuel tank.

SECTION 5 - INSTALLATION GUIDE FOR GENERATOR READY KIT  
NOTE: Balance must be maintained when  
moving circuit locations from main electrical  
distribution panel to emergency load center.  
Circuit breaker positions alternate buss bars  
vertically. Circuits sharing a neutral wire should  
either be moved together to adjacent positions  
in emergency load center or not moved. If you  
are unsure of proper procedure or if your  
installation differs from that described in this  
guide, consult a licensed professional at this  
time.  
10b. In your main panel, remove the black (hot) wire from  
a circuit breaker that protects a circuit you want to  
have powered in the event of a power failure. Wire  
nut the black wire to the matching circuit lead wire  
from the emergency circuit breaker from load center  
in the transfer switch. (All circuit wires are color  
coded and labeled for easy identification). Repeat  
this process with remaining circuits to be powered  
by the generator. White wires (neutral) in your main  
distribution panel should remain connected to  
neutral bar. It is not necessary to move them. The  
emergency load center in the transfer switch  
supplies the following circuits: (5) 15A/120V, (3)  
20A/120V, (1) 20A/240V and (1) 30A/240V.  
10a. Remove the main electrical distribution panel cover.  
Remove appropriate size knockout from the bottom  
or side of the main panel. (A 2-foot flexible conduit  
is pre-wired from the transfer switch with built-in  
load center). Remove threaded lock nut from  
conduit coupling. Feed all wires through knockout  
into main panel. Slip lock nut over wires and tighten  
securely onto conduit coupling.  
11 Install 70 AMP Circuit Breaker  
10a Connection of Emergency Circuits  
11. Install the 70 Amp double pole circuit breaker that  
you have purchased into main electrical distribution  
panel. This circuit breaker must be compatible with  
your main electrical distribution panel. It may be  
necessary to reposition remaining circuit breakers  
or remove circuit breakers that have been  
disconnected to accommodate the insertion of the  
70 Amp double pole circuit breaker. Connect white  
wire to the main distribution panel neutral bar.  
Connect solid green wire to main electrical panel  
ground bar. Connect the black and red wires to the  
70 Amp double pole circuit breaker. Replace  
electrical distribution panel cover.  
NOTE: Circuits to be moved must be protected by same  
size breaker. For example, a 15 amp 120V circuit in  
emergency load center will replace a 15 amp 120V  
circuit in main panel.

SECTION 6 - OPERATION OF GENERATOR WITH GENERATOR READY KIT  
GENERATOR READY KIT  
USING THE GENERATOR READY KIT WITH ULTRA SOURCE PORTABLE GENERATOR  
The GUARDIAN® Generator Ready Kit gives you the ability to hook up a GUARDIAN® ULTRA SOURCE portable generator to provide  
power safely and conveniently to vital items in your home including hard wired items. Included in the kit is a 5 foot electrical power  
cord and a 5 foot DC signal harness. The power cord contains 4 wires (black & red), neutral (white) and ground (green) wires. At  
one end are the terminal connectors. At the other end is the male connector (NEMA 14-50) which plugs into the GUARDIAN® ULTRA  
SOURCE portable generator’s control panel. To install this option, insert the terminal wire end of the power cord into the bottom  
of the external connection box through the conduit clamp (not included) from the outside. Allow  
about an inch of the power cord insulation to enter beyond the clamp to the inside of the box.  
TIghten clamp securely. Attach ground wire (green) to the bottom of the box using the supplied  
ground screw and pre-drilled hole. Connect red, black and white wires each to separate lug posts.  
Make sure hold down nuts are tightened securely. The 5 foot DC signal harness allows semi-  
automatic transfer switch operation. You simply attach the four-pin plug to its mating plug within  
the external connection box. At the other end is a V-type connector that plugs into the 12-volt DC  
receptacle on the portable generator control panel. Instructions for these items are detailed on the  
following page (Page 25).  
CAUTION: If you are connecting the 5 foot power cord after the 30 foot conduit has been connected inside of the external  
connection box you must match the black, red and white wires to the lugs of the wires previously placed.  
(For example: black to black; red to red, etc.) Failure to match wires may result in damage to generator and house wiring.

SEMI-AUTOMATIC TRANSFER OPERATION USING GUARDIAN® PORTABLE GENERATOR  
TRANSFER TO GENERATOR POWER SOURCE WHEN  
UTILITY POWER FAILS  
TRANSFER BACK TO UTILITY POWER SOURCE  
When utility power has been restored, you will want to  
transfer back to that source and shut down the generator.  
This can be accomplished as follows:  
1. Connect ground strap to generator’s grounding lug  
and to grounding rod.  
2. Set the generator’s 50 amp circuit breaker to its OFF  
1. Set the generator’s 50 amp circuit breaker to its OFF  
(or open) position.  
(or open) position.  
3. Insert the NEMA 14-50 plug (from the power cord that  
you have installed) into the mating receptacle on the  
generator control panel.  
4. Start the generator.  
5. Let the engine stabilize and warm up for a few minutes.  
6. Insert the V-type plug (on the DC signal harness  
you have connected within the external connection  
box) into the 12 volt DC receptacle on the generator  
control panel. The insertion of this plug will send a  
signal to the transfer switch to shift the contactor to  
the standby position.  
2. Remove the V-type plug (on the DC signal harness  
that was connected within the external connection  
box) from the 12 volt DC receptacle on the generator  
control panel. The removal of this plug will send a  
signal to the transfer switch to shift the contactor  
back to the utility position and allow the circuits of  
the home to again be powered by the incoming utility.  
3. Let the engine run for a minute or two at no-load to  
stabilize the internal temperatures.  
4. Turn off the generator.  
After utilizing the 5 ft. electrical power cord, 5 ft. DC signal  
harness and ground strap for operation with the GUARDIAN®  
ULTRA SOURCE portable generator you must disconnect and  
remove them. Open the external connection box. Remove the  
fasteners holding the Black, Red, White, and Green wires in  
place. Remove wires from threaded lugs and from under  
ground screw. Replace fasteners and ground screw. Loosen  
the cable clamp and slide the power cord out of the external  
connection box. Disconnect the 4-pin plug from its mating half  
within the external connection box. Remove ground strap  
from the generator’s ground lug and from the grounding rod.  
Store the power cord, the DC signal harness and the ground  
strap with your GUARDIAN® ULTRA SOURCE portable  
generator for future use.  
7. Set the generator’s 50 amp circuit breaker to its’ ON  
(or closed) position to send the generator power to  
the load center in the transfer switch.  
Choose a lamp or light fixture located in a frequently  
occupied area of the house as a signal light to tell  
you when utility power has returned. This light  
should be on a utility powered circuit only so it  
operates independent of the generator.

(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.  
The ECS Warranty pertains only 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 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.

and will be provided without charge to the purchaser/owner. Such use shall not reduce Generac RCS Warranty obligations.  
(9) Unapproved, add-on, modified, counterfeit and/or "grey market" parts nay 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
