SAFETY RULES
Safety Rules
Cenerac Q-70G Recreational Vehicle Generator
SAVE THESE INSTRUCTIONS - The manufacturer suggests that these rules for safe
operation be copied and posted in potential hazard areas of the recreational vehicle,
Safety should be stressed to all operators and potential operators of this equipment. MM.
A
WARNING:
The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
Study these SAFETY RULES carefully before
installing, operating or servicing this equipment.
Become familiar with this manual and with the unit.
The generator can operate safely, efficiently and reli
ably only if it is properly installed, operated and main
tained. Many accidents are caused by failing to follow
simple and fundamental rules or precautions.
Generac cannot possibly 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
you use a procedure, work method or operating tech
nique Generac does not specifically recommend, you
must satisfy yourself that it is safe for you and others.
You also must make sure the procedure, work
method or operating technique that you choose does
not render the generator unsafe.
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
A
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.
A GENERAL HAZARDS A
For safety reasons, Generac recommends
that the installation, initial start-up and mainte
nance of this equipment is carried out by a
Generac Authorized Service Dealer.
The engine exhaust fumes contain carbon monox
ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust sys
tem must be installed properly, in strict compli
ance with applicable codes and standards.
Following installation, you must do nothing that
might render the system unsafe or in noncompli
ance with such codes and standards. The genera
tor compartment must be completely vapor sealed
from the vehicle interior. There must be no possi
bility of exhaust fumes entering the vehicle interi
or. Never operate this equipment with a leaking or
defective exhaust system.
Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
Adequate, unobstructed flow of cooling and venti
lating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage to
the generator. Do not alter the installation or per
mit even partial blockage of ventilation provisions,
as this can seriously affect safe operation of the
generator.
When working on this equipment, remain alert at
all times. Never work on the equipment when you
are physically or mentally fatigued.
Inspect the generator regularly, and contact your
nearest Generac Authorized Service Dealer immedi
ately for parts needing repair or replacement.
Before performing any maintenance on the genera
tor, disconnect its battery cables to prevent acci
dental start up. Disconnect the cable from the bat
tery 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.

ELECTRICAL HAZARDS
The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, ter
minals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards and barriers
are in place before operating the generator. If you
must work around an operating unit, stand on an
insulated, dry surface to reduce shock hazard.
Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.
During installahon onto the vehicle, have the genera
tor properly grounded (bonded) either by solid
mounting to the vehicle frame or chassis, or by
means of an approved bonding conductor. DO NOT
disconnect the bonding conductor, if so equipped.
DO NOT reconnect the bonding conductor to any
generator part tliat might be removed or disassem
bled during routine maintenance. If the grounding
conductor must be replaced, use only a flexible con
ductor that is of No. 8 American Wire Gauge (AWG)
copper wire minimum.
In case of accident caused by electric shock, imme
diately shut down the source of electrical power. If
this is not possible, attempt to free the victim from
the live conductor, AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting imple
ment, such as a rope or board, to free the victim
from the live conductor. If the victim is uncon
scious, apply first aid and get immediate medical
help.
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.
A
A
FIRE HAZARDS
For fire safety, the generator must be installed and
maintained properly. Installation always must
comply with applicable codes, standards, laws and
regulations. Adhere strictly to local, state and
national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator is installed in
accordance with the manufacturer’s instructions
and recommendations. Following proper installa
tion, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regu
lations.

Extinguishers rated “ABC” by the National Fire
Protection Association are appropriate for use on
the recreational vehicle generator electrical system.
Keep the extinguisher properly charged and be
familiar with its use. If you have any question per
taining to fire extinguishers, consult your local fire
department.
A
EXPLOSION HAZARDS
Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no com
bustible materials are left in the generator com
partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround
ing the generator clean and free from debris.
Gasoline is extremely FLAMMABLE and its vapors
are EXPLOSrVTl. Do not permit smoking, open
flame, sparks or any source of heat in the vicinity
while handling gasoline. Comply with all laws gov
erning the storage and handling of gasoline.
This generator may use liquid propane (LP) gas as
a fuel. LP gas is highly EXPLOSIVE. The gas is
heavier than air and tends to settle in low areas
where even the slightest spark can ignite the gas
and cause an explosion.

DANGER
For fire safety, the generator must have been
A
properly installed in compliance with ANSI
119.2-1975/NFPA 501C-1974, "Standard for
Recreational Vehicles, Part III - Installation of
Electrical Systems." The generator also must
have been installed in strict compliance with
the manufacturer's detailed installation instruc
tions. After installation, do nothing that might
render the unit in noncompliance with such
codes, standards and instructions.
You can use this generator to supply electrical power for
operating 230-volt, single-phase, 50 Hertz, AC electrical
loads. These loads can require up to 7,000 watts (7.0
kW) of power, but cannot exceed 30.4 AC amperes of
current at 230 volts.
Owners/Operators should make sure nothing is done
during installation that might render the unit unsafe
or in noncompliance with applicable codes standards
and instructions. They should be sure the unit has
been installed to allow adequate ventilation for cool
ing and exhaust air.
1.4 SAFETY
Before attempting to use the generator set, carefully
read the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We sug
gest copying and posting the “Safety Rules” in poten
tial hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
1.5 GENERATOR AC
CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings. These two-stator windings supply
electrical power to customer electrical loads by
means of a dual two-wire connection system. Note,
however, that the neutral is grounded.
Figure 1.1 - Connections for 230 Volts Only
--------M. CAUTION M.
Do not overload the generator. Some installa
A
tions may require that electrical loads be alter
nated to avoid overloading. Applying excessive
ly high electrical loads may damage the genera
tor and may shorten its life. Add up the rated
watts of all electrical lighting, appliance, tool
and motor loads the generator will power at
one time. This total should not be greater than
the wattage capacity of the generator. If an
electrical device nameplate gives only volts and
amps, multiply volts times amps to obtain watts
(volts X amps = watts). Some electric motors
require more watts of power (or amps of cur
rent) for starting than for continuous operation.

GENERAL
INFORMATION
Section 1 - General Information
Generac Q-70G Recreational Vehicle Generator
1.6 SPECIFICATIONS
♦ 1.6.1 FUEL REQUIREMENTS
These generators are equipped with a gasoline fuel sys
tem. Depending on the installation, the generator may
have either a separate fuel tank, or it may “share” the
vehicle engine’s fuel tank.
NOTE:
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle engine’s pickup tube. Such an
arrangement causes the generator engine to “run
out of gas” while adequate fuel for the vehicle
remains in the tank.
lb reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded REG
ULAR grade gasoline is an acceptable substitute.
NOTE:
Using unleaded gasoline contributes to longer
engine valve life by reducing lead and carbon
deposits.
---------Jk CAUTION Jk---------------
Generac does not recommend using any
gasoline containing alcohol (such as "gasohol").
If you use any gasoline containing alcohol, it
must not contain more than 10 percent ethanol,
and it must be removed from the generator
during storage. Do NOT use any gasoline
containing methanol. If you use gasoline with
alcohol, inspect more frequently for fuel leaks
and other abnormalities.

♦ 2.1.3 FUSE
The fuse protects the engine’s DC control circuit
against electrical overload. If the fuse element has
melted open due to overloading, the engine cannot be
cranked. If you must replace the fuse, use only an
identical replacement.
♦ 2.1.4 MAIN BREAKER
The main breaker protects the generator’s AC output
circuit against overload and provides a method of
turning OFF the generator’s 115/230-volt AC output
to the vehicle circuits. This generator has two 30-amp
circuit breakers.
2 J AUTOIVlATiC CHOKE
This engine is equipped with an automatic choke that
consists of two main components: a choke solenoid
and prechoke.
♦ 2.3.1 CHOKE SOLENOID
During engine cranking (Start/Stop switch at
START), a solid-state choke module signals the
choke solenoid to activate and cycle (choke on/choke
off) until the engine starts. The choke solenoid thus
opens and closes the carburetor choke valve only
when the engine is cranking. When the engine starts,
the choke stops cycling,

♦ 2.3.2 PRECHOKE
The choke system also has a temperature-sensitive
metal strip that adjusts choke valve angle according
to ambient temperatures (i.e., in cold ambient tem
peratures, choke valve closes more). Once the engine
starts, an element heats the temperature-sensitive
strip to a normal operating condition, opening the
choke valve. This may take about three minutes in
cooler weather.
2.4 BEFORE STARTING THE ENGINE
NOTE:
Instructions and information in this manual
assume the generator has been properly installed,
connected, serviced, tested and adjusted by a
qualified installation technician or installation
contractor.
♦ 2.4.1 [NSTALLATION

pleted so it complies with all applicable codes, stan
dards and regulations and with the manufacturer's
recommendations.
♦ 2.4.2 ENGINE LUBRICATION
Have the engine crankcase properly serviced witli the
recommended oil before starting. Refer to Section 1.6.3
(Page 6) and Sections 3.1 and 3.2 (Page 11) for oil ser
vicing procedures and recommendations.
------
Jk CAUTION M
Any attempt to crank or start the engine before
A
you have properly serviced it with the recom
mended oil may result in an engine failure.
♦ 2.4.5 FUEL SUPPLY___________________
The engine must have an adequate supply of proper
fuel to operate. Before starting it, check that sufficient
fuel is available.
Depending on the installation, the generator may
have either a separate fuel tank, or it may “share”
the vehicle engine’s fuel tank.
♦ 2.4.4 COOLING AND VENTILATING AIR
Air inlet and outlet openings in the generator com
partment must be open and unobstructed for contin
ued proper operation. Without sufficient cooling and
ventilating airflow, the engine/generator quickly over

transfer switch).
2.6 STOPPING THE GENERATOR
1. Turn OFF all electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).
2. Let generator run at no-load for a few minutes, to
stabilize internal engine generator temperatures.
3. Place the Start/Stop switch in its STOP position.
2.7 APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator,
observe these guidelines:
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
• DO NOT overload the generator.
• 2.7.1 LETTING THE ENGINE STABILIZE
The generator supplies correct rated voltage only at
the proper governed speed. Some electrical appli
ances may be extremely sensitive to voltage. Incorrect
voltages can damage such appliances.
If electrical loads are applied at reduced operating
speeds, such loads Imposed on the engine when suffi
cient power is not available may shorten engine life.
Never turn ON electrical loads until after the generator
engine has started and stabilized at no-load.
• If a load does not show its rated wattage, multiply
that load’s rated ’VOLTS times AMPS to obtain
WATTS.
• Induction type motors (such as those that run the
vehicle’s furnace fan, refrigerator, air conditioner,
etc.) need about 2-1/2 times more watts of power
for starting than for running (for a few seconds
during motor starting). Be sure to allow for this
when connecting electrical loads to the generator.
F'irst, figure the watts needed to start electric
motors in the system. To that figure, add the run
ning wattages of other items that will be operated
by the generator.
• Do not apply heavy electrical loads for the first two
or three hours of operation.
2.8 PROTECTION SYSTEMS
• 2.8.1 LOW OIL PRESSURE SWITCH
This switch (Figure 2.3) has normally open (N.O.) con
tacts that are held open by engine oil pressure during
cranking and operating. Should oil pressure drop
below a preset level, switch contacts close, and the
engine automatically shuts down. The unit should not
be restarted until oil is added.
• 2.8.2 HIGH TEMPERATURE SWITCH
This switch (Figure 2.3), which has normally open
(N.O.) contacts, is mounted near the oil filter. The
contacts close if the temperature should exceed
approximately 284” F (140” C), initiating an engine
shutdown.

_____________
• 2.7.2 DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/arnperage capacity of
your generator on the generator data decal (see
Section 1.1 on Page 4).
Applying electrical loads in excess of the unit’s rated
capacity will cause the engine/generator to automati
cally shut dowir.
To avoid overloading, add up the wattage of all con
nected electrical lighting, appliance, tool and motor
loads. This total should not be greater than the gen
erator’s rated wattage capacity.
• Most lighting, appliance, tool and motor loads indi
cate their required watts on their nameplate or
data plate. For light bulbs, simply note the wattage
rating of the bulb.

♦ 2.8.3 FIELD BOOST
The Controller Circuit Board houses a field boost
diode and resistor that are not part of the automatic
choke circuit. These two components are part of a
“field boost” circuit (Figure 2.4). During engine
cranking only, a positive DC (battery) voltage is deliv
ered through the diode, resistor, brushes and slip
rings, and the generator rotor. Application of this
voltage to the rotor “flashes the field” whenever it is
started. Flashing of the field each time the generator
starts makes sure that a sufficiently strong magnetic
field is available to produce “pickup” voltage in the
stator windings.
Figure 2.4 - Field Boost Circuit
CLOSEST TO
BEARING
♦ 2.8.4 OVERVOLTAGE PROTEQION________________
A solid-state voltage regulator (Figure 2.5) controls
the generator's AC output voltage. This regulator sup
plies an excitation current to the rotor. By regulating
the rotor’s excitation current, the strength of its mag
netic field is regulated and, in turn, the voltage deliv
ered to connected electrical loads is controlled. When
the AC frequency is 50 Hertz, voltage is regulated at
115 volts.

tronic equipment.
2.9 ADDITIONAL INFORIVIAIION
• 2.9.1 25-HOUR BREAK-IN PERIOD
The first 25 hours of operation is the break-in period
for the generator. Properly breaking in the generator
is essential to minimize fuel consumption and pro
vide maximum engine performance. During this 25hour break-in period, follow this procedure:
» Run the unit at varying electrical loads to help seat
the engine piston rings properly.
• Check the engine oil level frequently. Add oil if
needed. It is normal for the generator engine to
consume more oil than is normal until the piston
rings have properly seated.
• For the 75-hour operation following the break-in
period, avoid light electrical loads. Load the
generator at 50 percent (or more) of its rated
wattage capacity. Repeated light loads during these
75 hours can cause improper seating of engine pis
ton rings, resulting in blowby and high oil con
sumption.
• After operating the unit for 25 hours, complete the
tasks recommended under Section 2.10.2.
• 2.9.2 25-HOUR CHECK-UP______________________
After the 25-hour break-in period, contact a Generac
Authorized Service Dealer for the following mainte
nance. The vehicle owner is responsible for any
charges:
• Change the engine crankcase oil and oil filter.
• Inspect the cooling and ventilation openings.
• Check the engine ignition system.
• Inspect the entire electrical system.
• Inspect the engine exhaust system.
• 2.9.3 OPERATION IN HIGH GRASS
OR BRUSH
_______________
-A WARNING A~
Never operate the generator while the vehide
is parked over high grass, weeds, brush,
leaves or any other combustible substance.
Such materials can ignite and burn from the
heat of the exhaust system. The generator
exhaust system becomes extremely hot dur
ing operation and remains hot for a long time
after it has shut down.

3.1 CHECKING THE ENGINE OIL
LEVEL
For oil capacities and requirements, see "Engine Oil
Requirements,” Section 1.6.2 (Page 6). Check the
engine crankcase oil level at least every eight hours of
operation, or before you use it. To check the engine
oil level, proceed as follows (see Figure 3.1):
1.
Be sure the generator is as level as possible.
2.
Remove the dipstick and wipe it dry with a clean,
lint-free cloth.
3.
Install and tighten the dipstick cap; then, remove
it again. The oil level should be at the dipstick
“Pull” mark.
If necessary, remove the oil fill cap on the rocker
cover and slowly add oil until it reaches the dip
stick “Pull” mark. DO NOT FILL ABOVE THE
"FULL’ MARK.
--------Ak CAUTION M
Never operate the engine with the oil level
A
below the "Add" mark on the dipstick. Doing
this could damage the engine.
5. Install and tighten the oil fill cap and the dipstick
before operating the engine.
---------------
7. Remove the dipstick and fill crankcase with the
proper type and amount of recommended oil (see
Section 1.6.2, Page 6). The engine crankcase can
hold about 1.4 liters. DO NOT FILL ABOVE THE
“FULL’ MARK.
8. Install and tighten the dipstick before operating
the engine.
9. Start the engine and check for leaks.
NOTE:
Check the oil level and fill to the “FULL” mark
after checking for leaks. The filter will retain some
oil.

Location of Oil Drain Plug
3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
• Change the engine oil after the first 25 hours of
operation (after the 25-hour break-in period, see
Section 2.9.1, Page 10). Thereafter, change the
oil every 50 operating hours. Change the oil more
frequently if operating consistently under heavy
load or at high ambient temperatures.
• Change the engine oil filter after the first 25 hours
of operation, and every 100 operating hours there
after.
To change the oil and/or oil filler, proceed as
follows:
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF
the engine.
2. With the engine still warm from running, remove
the oil drain plug (Figure 3,1). Drain the oil into
a suitable container.
3. After the oil has drained, replace the oil drain plug.
{If only changing the oil, go to step 7.)
4. With the oil drained, remove the old oil filter by
turning it counterclockwise (Figure 3,2).
5. Apply a light coating of clean engine oil to the gas
ket of the new filter.
6. Screw the new filter on by hand until its gasket
lightly contacts the oil filter adapter. Then, tight
en the filter an additional 3/4 to one turn.

3.7 SPARK ARRESTOR MUFFLER
If the generator is not equipped with a spark arrestor
exhaust muffler and is to be used on any forest cov
ered, brush covered or grass covered unimproved
land, you may have to install a spark arrestor. The
spark arrestor must be maintained in effective work
ing order by the vehicle owner/operator.
For assistance in ordering, installing and maintaining
spark arrestor exhaust mufflers, contact your nearest
Generac Authorized Service Dealer.
Exhaust mufflers supplied by Generac are spark
arrestor types. Generac exhaust mufflers for recre
ational vehicle generators do not have a spark
arrestor screen, but are of the more efficient “toroid”
or “swirl” type. To remove carbon and combustion
deposits from such mufflers, remove the plug from
the muffler and run the engine for approximately 15
minutes. Shut down the engine, let the muffler cool
and install the plug.
---------ià WARNING Æ
Be sure to reinstall the muffler plug tightly.
Engine vibration could cause a loose plug to
fall out. Without the plug in place, hot engine
exhaust is directed out the opening. This hot
exhaust, depending on the installation, could
be directed to areas not able to withstand the
extreme heat such as wooden floor boards or
other flammable material. This could result in a
fire.
--------------
3.8 CLEANING THE GENERATOR
Keep fhe generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and mois
ture to accumulate on generator windings will have
an adverse effect on the insulation resistance of those
windings.
When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This causes a
reduced insulation resistance and will eventually
cause problems. Dirt will make the problem worse,
since dirt tends to hold moisture in contact with
windings. Salt (as from sea air) also will worsen the
problem since it tends to absorb moisture from the
air. Salt and moisture, when combined, form a good
electrical conductor.
-A CAUTION A~
Do not use a forceful spray of water to clean
the generator. Water will enter the generator
A
interior and cause problems, and may also cont
aminate the generator fuel system.
3.9 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in use.
The generator battery should be inspected as follows;
♦ 5.9.1 WEEKLY
• Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
♦ 3.9.2 EVERY SIX MONTHS
• Have the state of charge and condition checked.
This should be done with an automotive-type bat
tery hydrometer.
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batter
ies and the required precautions. Keep unautho
rized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.

DANGER
Do not dispose of the battery in a fire. The
A
battery is capable of exploding. Storage batter
ies give off explosive hydrogen gas. This gas
can form an explosive mixture around the bat
tery for several hours after charging. The
slightest spark can ignite the gas and cause an
explosion. Such an explosion can shatter the
battery and cause blindness or other injury.
Any area that houses a storage battery must be
properly ventilated. Do not allow smoking,
open flame, sparks, or any spark producing
tools or equipment near the battery. Discharge
static electricity from your body before touch
ing the battery by first touching a grounded
metal surface.
A battery presents a risk of electrical shock
A
and high short circuit current. The following
precautions are to be observed when working
on batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connecting
or disconnecting battery terminals; and
• Do not use any jumper cables or booster battery to
crank and start the generator engine. If any battery
has discharged, remove it for recharging.
--------Mk WARNING ik
Do not open or mutilate the battery. Released
A
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
A
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
thoroughly 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) 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.

CALIFORNIA AND FEDERAL EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board (GARB) and the United States Environmental Protection Agency (EPA), together with
Generac Power Systems, Inc. (Generac), are pleased to explain the Emission Control System Warranty on your new engine.*
New utility, and lawn and garden equipment engines must be designed, built smd equipped to meet stringent anti-smog stan
dards for the state of California and the federal government. Generac will warrant the emission control system on your
engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modification or improp
er maintenance of your engine.
Your emission control system may Include parts such as the carburetor, ignition and exhaust systems. Generac will repair
your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.
MANUFACTURER'S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
Emissions control systems on 1997 and later model year engines are warranted for two years as hereinafter noted. If, dur
ing such warranty period, any emission-related component or system on your engine is found to be defective in materials or
workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.
PURCHASER'S/OWNER'S WARRANTY RESPONSIBILITIES:
As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory
supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance
on your engine. However, Generac cannot deny warranty solely because of the lack of receipts or for your failure to ensure
the completion of all scheduled maintenance.
As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or
responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper maintenance or unap
proved modifications, or the use of counterfeit and/or ‘grey market’ parts not made, supplied or approved by Generac.
You are responsible for presenting your engine to a Generac Authorized Warranty Service Facility as soon as a prob
lem occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

Limited Warranties for Generac Power Systems, Inc.,’’ which is enclosed herewith on a separate sheet, also provided to you
by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in
terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where
the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Warranty describe
important rights and obligations with respect to your new engine.
Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty ser
vice, evidence must be presented showing the date of the sale to the original purchaser/owner. The pimchaser/owner shall
