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 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.
• 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.
DANGER
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.
Potentially lethal voltages are generated by
ꢃ
these machines. Ensure all steps are taken to

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.
• 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 sys-
tem.
• 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 5A
and 15A fuses 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 rope or board, to free the victim from the
live conductor. If the victim is unconscious, 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.
• 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.

1.2 PROTECTION SYSTEMS
DANGER
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:
Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and
regulations.
ꢀ
1. Low Oil Pressure Sensor
2. High Temperature Sensor
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 described below.
3. Overcrank
4. Overspeed
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents
for damage.
• This standby generator set has been factory sup-
plied with a weather protective enclosure that is
intended for outdoor installation only.
1.3 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.
If this generator is used to power electrical load
ꢃ
circuits normally powered by a utility power
2. The utility voltage being supplied to the unit is
being sensed by the Control PCB. If the utility
sense voltage is not connected to the unit or if it
is below 168 volts AC, then the system set light
will flash rapidly. This indicates that if the AUTO/
OFF/MANUAL switch is placed in the Auto posi-
tion , the generator will start.
source, it is required by code to install a trans-
fer switch. The transfer switch must effectively
isolate the electrical system from the utility
distribution system when the generator is oper-
ating (NEC 700, 701 and 702). Failure to isolate
an electrical system by such means will result in
damage to the generator and also may result in
injury or death to utility power workers due to
backfeed of electrical energy.
3. The “Not In Auto” dip switch is set to the OFF
position on the control board.
4. No alarms are present, for example, low oil pres-
sure, high temperature, etc.
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 his or her signature under the
consignor's memo of loss or damage.
If there is loss or damage 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.

3. Remove the battery (if installed).
1.6 FUEL REQUIREMENTS
AND RECOMMENDATIONS
4. Disconnect wire #0 and wire #14 from the gas
solenoid on top of the demand regulator.
With LP gas, use only the vapor withdrawal
system. This type of system uses the vapors formed
above the liquid fuel in the storage tank.
5. Remove the carburetor fuel hose from the outlet
port of the demand regulator.
6. Remove the demand regulator by removing the
fastener that retains the regulator mounting
bracket.
7. Remove the square headed steel pipe plug from
outlet port #1 and the brass hose barb fitting
from outlet port #2.
8. Refit the brass hose barb fitting to outlet port #1
and the square headed steel pipe plug to outlet
port #2.
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
Section 1.9 for instructions on reconfiguration of the
fuel system.
9. Reverse procedure steps 1-5 to reinstall demand
regulator.
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.
10. Take the plastic plug supplied in the poly-bag
with the generator and press it into the 3/4” hole
on the bottom of the air cleaner base (Figure
4.6).
Required fuel pressure for natural gas is 5 inches to
7 inches water colum (0.18 to 0.25 psi); and for
liquid propane, 10 inches to 12 inches of water
column (0.36 to 0.43 psi).
11. Reverse the procedure to convert back to natural
gas.

Air-cooled 7 kW, 12 kW and 15 kW Generators
NOTE:
1.10 BATTERY INSTALLATION
Fill the battery with the proper electrolyte fluid if
necessary and have the battery fully charged before
installing it.
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.
Before installing and connecting the battery, complete
the following steps:
1. Set the generator's AUTO/OFF/MANUAL switch to
OFF.
2. Turn off utility power supply to the transfer
switch.
3. Remove the 5 amp fuse from the generator con-
trol panel.
1.11 THE BATTERY
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.
If the AUTO/OFF/MANUAL switch is not set to its
ꢁ
OFF position, the generator can crank and start
as soon as the battery cables are connected. If
the utility power supply is not turned off, spark-
ing can occur at the battery posts and cause an
explosion.
When replacing the battery, use the following type of
battery: Group 26/26R 12-volt battery with a rating
of 350 cold-cranking amps minimum for 7 kW; 525
cold-cranking amps minimum for 12 and 15 kW at
-18º C (0º F) minimum. 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 connected and terminals
are tight. Observe battery polarity when connecting
the battery to the generator set.
Battery cables were factory connected at the genera-
tor (Figure 1.5). Connect cables to battery posts as
follows:
4. Connect the red battery cable (from starter con-
tactor) to the battery post indicated by a positive,
POS or (+).
5. Connect the black battery cable (from frame
ground) to the battery post indicated by a nega-
tive, NEG or (—).
6. Replace the 5 amp fuse in the generator control
panel.

2. Turn OFF the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
With the switch set to AUTO, the engine may
crank and start at any time without warning.
ꢀ
Such automatic starting normally occurs when
utility power source voltage drops below a pre-
set level or during the normal exercise cycle. To
prevent possible injury that might be caused by
such sudden starts, always set the switch to OFF
and remove both fuses before working on or
around the generator or transfer switch. Then,
place a “Do Not Operate” tag on the generator
panel and on the transfer switch.
3. The unit will start, and the transfer switch will
transfer to standby.
4. Run the unit for one hour at 25 percent load.
5. Run the unit for one hour at 50 percent load.
6. Run the unit for one hour at 75 percent load.
7. Run the unit for one hour at 100 percent load.
8. Turn ON the utility power supply to the transfer
switch, which will allow the transfer switch to
transfer back to utility power. The unit will con-
tinue to run for one minute and then shut down.
9. Allow the unit to cool.
3.3 AUTOMATIC TRANSFER
OPERATION
To select automatic operation, do the following:
1. Make sure the transfer switch main contacts are
set to their “Utility” position, i.e., loads connected
to the utility power source (Figure 3.2).
2. Be sure that normal utility power source voltage
is available to transfer switch terminal lugs N1
and N2.
10. Drain the oil and remove the oil filter. Replace
the oil filter according to Section 4.4, “Changing
the Oil Filter”. Replace the oil with synthetic oil
as recommended in Section 4.3, “Changing the
Engine Oil”.
11. The generator is now ready for service.
3. Set the generator’s AUTO/OFF/MANUAL switch to
AUTO.
3.2 USING THE AUTO/OFF/MANUAL
SWITCH (FIGURE 3.1)
4. Set the generator’s main circuit breaker to its ON
(or closed) position.
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
Section 3.4, “Sequence of Automatic Operation.”
ꢀ
3.2.1 “AUTO” POSITION
Selecting this switch position activates fully automatic
system operation. It also permits starting and exercising
of the engine every seven days with the exercise timer
(see Section 3.6). This position also is used for remote
starting, when it is set up.
3.4 SEQUENCE OF AUTOMATIC
OPERATION
ꢀ
3.2.2 “OFF” POSITION
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).
This switch position shuts down the engine. This
position also prevents automatic operation.
ꢀ
3.2.3 “MANUAL” POSITION
Set the switch to MANUAL to crank and start the
engine. Transfer to standby power will not occur
unless there is a utility failure.

preset level, generator circuit board action signals the
transfer switch to transfer loads back to that power
supply. After retransfer, the engine is signalled to shut
down.
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 elec-
trical shock.
ꢃ
The actual sequence of operation is controlled by
sensors and timers on a control logic circuit board,
as follows:
A.Utility Voltage Dropout Sensor
4. Use the manual transfer handle inside the trans-
fer switch to move the main contacts to their
“Standby” position, i.e., loads connected to the
standby power source (Figure 3.2).
• This sensor monitors utility source voltage.
• If utility source voltage drops below about 60
percent of the nominal supply voltage, the sensor
energizes a 15-second timer.
• Once the timer has expired, the engine will crank
and start.
5. To crank and start the engine, set the AUTO/OFF/
MANUAL switch to MANUAL.
6. Let the engine stabilize and warm up for a few
minutes.
B.Engine Warm-up Time Delay
• This mechanism lets the engine warm up for
about 10 seconds before the load is transferred
to a standby source.
7. Set the generator’s main circuit breaker to its ON
(or closed) position. The standby power source
now powers the loads.
C.Standby Voltage Sensor
Figure 3.2 – Manual Transfer Switch Operation
• 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.
D.Utility Voltage Pickup Sensor
• This sensor monitors utility power supply volt-
age. When that voltage is restored to above 70
percent of the nominal source voltage, a retrans-
fer time delay starts timing.
E.Retransfer Time Delay
• This timer runs for about 15 seconds.
• At end of a 15-second delay, circuit board action
de-energizes the transfer relay in the transfer
switch.
• Retransfer to utility power source then occurs.
F. Engine Cool-down Timer
• When the load is transferred back to utility power
source, the engine cool-down timer starts tim-
ing.
• The timer will run for about one minute, and the
generator will then shut down.
ꢀ
3.5.2 TRANSFER BACK TO UTILITY POWER

POWER SOURCE
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.
To start the generator and activate the transfer switch
manually, proceed as follows:
1. Set the generator’s main circuit breaker to its
OFF (or open) position.
2. Set the generator’s AUTO/OFF/MANUAL switch

starting. The unit will crank and rest for a preset time
limit. Then, it will stop cranking, and the LED 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.
NOTE:
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. The exerciser WILL NOT work if
dip switch 2 (Remote Not Auto) on the controller
printed circuit board is ON.
If the fault is not repaired, the overcrank feature
will continue to activate.

4.1 FUSE
The generator panel’s 15 amp fuse (Figure 4.1) pro-
tects the DC control circuit against overload. The fuse
is wired in series with the battery output lead to the
panel. If the fuse element has melted open, the engine
cannot crank or start. Replace the fuse using only an
identical 15-amp replacement.
The generator panel’s 5 amp fuse protects the battery
charge circuit against overload. If the fuse element has
melted open, battery charging will not be possible.
Replace the fuse using only an identical 5 amp replace-
ment. To remove fuse, push cap down and rotate coun-
terclockwise.

ꢀ
4.3.1 ENGINE OIL RECOMMENDATIONS
1. With the oil drained, remove the old oil filter by
turning it counterclockwise.
2. Apply a light coating of clean engine oil to the
gasket of the new filter. See Section 1.5.1 for rec-
ommended filter.
Use oil of American Petroleum Institute (API) Service
Class SG, SH or SJ. Use all season SAE 5W-30
Synthetic oil. Organic break-in oil is required before
using synthetic oil.
3. 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 (Figure
4.4).
4. Refill with the proper recommended oil (see
Section 4.3.1). See Section 1.5.2 for oil capaci-
ties.
NOTE:
The unit is supplied with “break-in” oil. See the
“Break-in Procedure,” Section 3.1, for the first
required oil change.
5. Start the engine and check for leaks.

4.7 BATTERY MAINTENANCE
The battery should be inspected per the “Service
Schedule,” Section 4.13. The following procedure
should be followed for inspection:
Screw
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 BATTER-
IES.
3. Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
Cover
Filter
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding.
ꢁ
A battery presents a risk of electrical shock
ꢃ
and high short circuit current. The following pre-
cautions are to be observed when working on
batteries:
4.6 SPARK PLUG(S)
• Remove watches, rings or other metal objects;
Reset the spark plug(s) gap or replace the spark
plug(s) as necessary. See Section 4.13 for mainte-
nance requirements.
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery; and
• Disconnect charging source prior to connecting or
disconnecting battery terminals.
1. Clean the area around the base of the spark
plug(s) to keep dirt and debris out of the engine.
Clean by scraping or washing using a wire brush
and commercial solvent. Do not blast the spark
plug(s) to clean.
2. Remove the spark plug(s) and check the condi-
tion. Replace the spark plug(s) if worn or if reuse
is questionable. See Section 4.13 for recommend-
ed inspection.
Do not open or mutilate the battery. Released
ꢀ
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.76 mm (0.030 inch)
for 7 kW and 0.50 mm (0.020 inch) for 12/15 kW
by carefully bending the ground electrode (Figure
4.8).
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 4.8 – Setting the Spark Plug Gap
• Where electrolyte contacts the eyes, immediately
flush thoroughly with water and seek medical
attention; and
SET PLUG GAP AT 0.76 mm/0.50 mm
(0.030 inch/0.020 inch)
• 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.
Lead-acid batteries present a risk of fire because
they generate hydrogen gas. The
ꢂ

Section 4 — Maintenance
Air-cooled 7 kW, 12 kW and 15 kW Generators
following procedures are to be followed:
Figure 4.10 - Valve Clearance Adjustment
• 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.
Rocker
Arm
Pivot Ball
Stud
Jam Nut
Valve
Stem
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.
Be sure the utility power supply is turned off, and
ꢁ
the 5A fuse is removed from the generator control
panel, or sparking may occur at the battery posts
as the cables are attached, causing an explosion.
4.8 ADJUSTING VALVE CLEARANCE
After the first six months of operation, adjust the
valve clearance in the engine.
• Install new valve cover gasket.
• Re-attach the valve cover.
NOTE:
Important: If feeling uncomfortable about doing this
procedure or the proper tools are not available, contact
the nearest Authorized Dealer for service assistance.
This is a very important step to insure longest life for
the engine.
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.
• Re-attach the spark plug wire to the spark plug.
• Repeat the process for the other cylinder.
To adjust valve clearance:
• 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.
4.9 COOLING SYSTEM
Air inlet and outlet openings in the generator compart-
ment must be open and unobstructed for continued
proper operation. This includes such obstructions as
high grass, weeds, brush, leaves and snow.
• 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.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it to
quickly shut down. (See Figure 4.9 for vent locations.)
Figure 4.9 – 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.

Section 10 – Warranty
Air-cooled 7 kW, 12 kW and 15 kW 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 there are any questions regarding the warranty rights and responsibilities, contact Generac at the following
address:

Section 10 – Warranty
Air-cooled 7 kW, 12 kW and 15 kW 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.
