GENERAL SAFETY RULES
THE MANUFACTURER SUGGESTS THAT THESE "RULES" FOR SAFE OPERATION BE COPIED AND
POSTED IN POTENTIAL HAZARD AREAS OF THE INDUSTRIAL VEHICLE. SAFETY SHOULD BE STRESSED
TO ALL OPERATORS AND POTENTIAL OPERATORS OF THIS EQUIPMENT.
Study these SAFETY RULES carefully before operating
or servicing applicable equipment. Become familiar
with this Owner's Manual and with your generator. Safe,
efficient and reiiable operation can only be achieved if
generator is properly installed, operated and main
tained. Many accidents are caused by failing to follow
simple and fundamental rules or precautions. The man
ufacturer suggests that these GENERAL SAFETY
RULES be copied and posted in potential hazard areas
of the industrial vehicle. Safety should be stressed to
all operators and potential operators of equipment.
The manufacturer cannot possibly anticipate every pos
sible circumstance that might involve a hazard. The
warnings 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 technique
Generac does not specifically recommend, you must
satisfy yourself that it is safe for you and others. You
must also make sure the procedure, work method or
operating technique that you chose does not render the
generator to be unsafe.
• For fire safety, the industrial mobile generator must
be properly installed and maintained. Installation
must always remain in compliance with applicable
codes and standards. In addition, the generator
must be installed in conformance to the
manufacturer’s detailed installation instructions.
Following installation, nothing must be done that
might render the generator in noncompliance with
such codes, standards and instructions.
• The RV generator produces extremely high and
dangerous electrical voltages and can cause dan
gerous, and possibly fatal, electrical shock. Avoid
contact with bare wires, terminals, etc. while the
unit is running. If you must work around an operat
ing generator, stand on an insulated, dry surface to
reduce shock hazard.
• Never work on this equipment or handle any elec
trical device while standing in water, while barefoot,
or while hands or feet are wet. Dangerous electri
cal shock will result.
• Have the generator properly grounded (bonded)
during installation onto the vehicle, either by solid
mounting to the vehicle frame or chassis or by
means of an approved bonding conductor. DO
NOT disconnect the bonding conductor, if so
equipped. DO NOT reconnect the bonding conduc
tor to any generator part that might be removed or
disassembled during routine maintenance. If the
grounding conductor must be replaced, use only a
flexible conductor that is of No. 8 AWG copper wire
minimum.
• Inspect the generator periodically. Repair or re
place all damaged or defective parts immediately.
• In case of accident caused by electric shock, shut
down the source of electrical power down at once.
If this cannot be done, free victim from live conduc
tor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a dry board, dry rope, or other non-con
ducting implement to free the victim from live con
ductor. If victim is unconscious, apply CPR (cardio
pulmonary resuscitation) and get medical help.
Inspect fuel system frequently for leaks or damage.
Repair or replace any damaged or leaking compo
nent immediately. Never attempt to change, alter
or modify the generator fuel system in any way that
might affect safety or compliance with applicable
codes and standards’.
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentra
tions, can cause unconsciousness or even death.
This exhaust system must have been properly in
stalled, in strict compliance with applicable codes
and standards. Following installation, you must do
nothing that might render the system unsafe or in
non-compliance with such codes and standards.
The generator compartment must be completely
vapor sealed from vehicle interior. There must be
no possibility of exhaust fumes entering the vehicle
interior. Never operate this equipment with a leak
ing or defective exhaust system.
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 conditions from
leaking exhaust gases, fuel leakage, oil leakage,
coolant leakage, etc.
Do not smoke around the generator. Wipe up any
fuel, oil and coolant spills immediately. Never leave
oily or fuel soaked rags in the generator compart
ment or on the generator itself. Keep the area
around the generator clean and free of debris.
Adequate ventilation is required to expel toxic
fumes and gasoline vapors from the generator com
partment. Do not alter the installation of this equip
ment in any manner that might obstruct air and
ventilation openings. Such openings must be kept
clear and unobstructed.
Keep hands, feet, clothing, etc., away from drive
belts, fans and other moving parts of this equip
ment. Never remove any drive belt or fan guards
while the unit is operating.
Some generators may use LP gas (propane) 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.
Before performing any maintenance on the gener
ator set, disconnect its battery cables to prevent
accidental start up. Disconnect the cable from the
battery post indicated by a NEGATIVE, MEG or (-)
first. Reconnect that cable last.

GENERATOR FAMILIARIZATION
GENERATOR APPLICABILITY
Q-55G and Q-70G generators have been designed and
manufactured for supplying electrical po\wer for recrea
tional vehicles. You should not modify the generator or
use it for any application other than for what it was
designed. If there are any questions pertaining to its
application, write or call the factory. Do not use the unit
until you have been advised by competent authority.
DANGER: FOR FIRE SAFETY, THE GENERATOR
MUST HAVE BEEN PROPERLY INSTALLED IN
COMPLIANCE WITH (1) ANSI 119.2-1975/NFPA
501C-1974 "STANDARD FOR RECREATIONAL
VEHICLES", PART III, "INSTALLATION OF ELEC
TRICAL SYSTEMS." THE GENERATOR ALSO
MUST HAVE BEEN INSTALLED IN STRICT COM
PLIANCE WITH THE MANUFACTURER’S DE
TAILED INSTALLATION INSTRUCTIONS. AFTER
INSTALLATION, DO NOTHING THAT MIGHT
RENDER THE UNIT IN NON-COMPLIANCE WITH
SUCH CODES, STANDARDS AND INSTRUC
TIONS.
You can use your generator set to supply electrical
power for operating one of the following electrical loads:
• Q-55G: 120 and/or 240 volts, single phase, 60 Hz
electrical loads. These loads can require up to 5500
watts (5.5 kW) of power, but cannot exceed 45.8 AC
amperes of current at 120 volts or exceed 22.9 AC
amperes at 240 volts.
• Q-70G: 120 and/or 240 volts, single phase, 60 Hz
electrical loads. These loads can require up to 7000
watts (7.0 kW) of power, but cannot exceed 58.3 AC
amperes of current at 120 volts or exceed 29.1 AC
amperes at 240 volts.
An INSTALLATION MANUAL was shipped with the
generator. That Manual contains manufacturer’s in
structions and recommendations for installing the unit
into an industrial vehicle. After installation, installers
should fonvard the Installation Manual to Owners/Operators for their information.
Owners/Operators have the responsibility to make sure
that nothing is done that might render the installation
unsafe or in non-compliance with applicable codes,
standards and instructions.
SAFETY
Before using the generator set, carefully read GEN
ERAL SAFETY RULES inside the cover. Comply with
these RULES to prevent accidents and damage to
equipment and/or property. Generac suggests copying
and posting the GENERAL SAFETY RULES to potential
operators of this equipment.
GENERATOR AC CONNECTION SYSTEM
These air-cooled Q Series generator sets are equipped
with dual stator AC power windings. These two stator
windings supply electrical power to customer electrical
loads by means of a dual 2-wire connection system.
The generator may have been installed so that units
only power 120 volts AC loads (Figure 1); or you can
wire them to connect both 120 and/or 240 volts AC
electrical loads. Be sure to remove the jumper between
the circuit breakers when connecting for 120/240 volts.
CAUTION: Do not overload the generator. Some
installations may require that electrical loads be
alternated to avoid overloading. Applying exces
sively high electrical loads may damage the gener
ator 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 areater than the wattage capac
ity 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 current) for starting than for continuous
operation.
INSTALLATION
This Owner’s Manual has been prepared under the
assumption that a competent, qualified technician in
stalled the generator into an industrial vehicle. We also
assume the installer complied with all applicable codes,
standards and regulations pertaining to installation.

OPERATING INSTRUCTIONS
GENERATOR CONTROL PANEL
Mounted on the generator control panel (Figure 2) are
the following features:
• Fuel Pump Primer: Before starting a cold engine
(it has not been started in more than two weeks),
you must press this switch to bring fuel from the tank
to the fuel pump. This rocker type switch springs
back into its original position when you release it.
• Start/Stop Switch: To crank and start the engine,
hold this switch at its START position. Release the
switch when the engine starts. To stop an operating
engine, place the switch in its STOP position. The
switch center position is the RUN position.
• 15 amp Fuse: Protects the engine DC control
circuit against electrical overload. If the fuse ele
ment has melted open due to overloading, the en
gine cannot be cranked. If you must replace it, use
only an identical 15 amp replacement fuse.
• Line Breakers: Protects generator’s AC output
circuit against overload, i.e., prevents unit from
exceeding wattage/amperage capacity. NP-50G
has one 20 amp breaker and one 30 amp breaker.
NOTE: If your "Q" Series generator has been recon
nected for dual voltage AC output (120/240 volts), you
can install line breakers having an amperage rating that
is different than stated above. The replacement line
breakers consist of two separate breakers with a con
necting piece between the breaker handles (so that both
breakers will operate at the same time). If the unit is
reconnected for dual voltage, it is no longer RVIA listed.

AUTOMATIC CHOKE
The engine is equipped with an automatic choke that
consists of two main components—choke solenoid and
prechoke.
Choke Solenoid: During engine cranking (start/stop
switch at START), a solid state choke module signals
the choke solenoid to actuate and cycle (choke
on/choke off) until 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 cycling stops.
Prechoke: The choke system also has a temperature
sensitive metal strip that adjusts the choke valve angle
according to ambient temperatures (i.e. in cold ambient
temperatures the choke valve closes more). Once the
engine starts, an element heats the temperature-sensi
tive strip to a normal operating condition, opening the
choke valve. This may take about 3 minutes in cooler
weather.

OPTIONAL REMOTE START/STOP PANEL
Optional remote mounted panels are available which
permit you to crank and start the generator from any
convenient location in the industrial vehicle. Figure 3
shows the Model 9042 remote panel which includes (a)
start/stop switch and (b) a generator run lamp.
You can also order Model 9043, a remote panel which
includes the (a) start/stop switch, (b) the generator run
lamp and (c) an hourmeter. The hourmeter provides a
continuous indication of engine-generator operating
time. Use the hourmeter for checking off periodic main
tenance requirements on the unit.
BEFORE STARTING THE ENGINE
IMPORTANT: INSTRUCTIONS AND INFORMATION
IN THIS MANUAL ASSUME THE GENERATOR HAS
BEEN PROPERLY INSTALLED, CONNECTED, SER
VICED, TESTED AND ADJUSTED BY A OUALIFIED
INSTALLATION TECHNICIAN OR INSTALLATION
CONTRACTOR.
• Installation: Generator installation must have
been properly completed so it complies with all
applicable codes, standards and regulations and
with the manufacturer’s recommendations.
• Engine Lubrication: Have engine crankcase
properly serviced with recommended oil before
starting. Refer to "Maintenance“ and "Specifica
tions” sections for oil servicing procedures and rec
ommendations.
CAUTION: Any attempt to crank or start the engine
before you have properiy serviced it with the recom
mended oii will result in an engine failure.
-6-
Fuel Supply: The engine must have adequate
supply of proper fuel to operate. Before starting,
check that sufficient fuel is available.
NOTE: On some installations, the generator en
gine may “share" the vehicle’s gasoline fuel tank
with vehicle engine. Some installations may pro
vide separate fuel tanks for generator and vehicle
engine.
Cooling and Ventilating Air: Air inlet and outlet
openings in the generator compartment must be
open and unobstructed for continued proper oper
ation. Without sufficient cooling and ventilating air
flow, the engine-generator quickly overheats which
causes it to quickly shutdown. Overheating could
also damage the unit or your vehicle.
Engine Exhaust Gases: Before starting the gen
erator engine, you should be sure there is no way
for exhaust gases to enter the vehicle interior and
endangering people or animals. Close windows,
doors and other openings in the vehicle that, if open,
might permit exhaust gases to enter the vehicle.
DANGER: THE GENERATOR ENGINE GIVES
OFF DEADLY CARBON MONOXIDE GAS
THROUGH ITS EXHAUST SYSTEM. THIS DAN
GEROUS GAS, IF BREATHED IN SUFFICIENT
CONCENTRATIONS, CAN CAUSE UNCON
SCIOUSNESS OR EVEN DEATH. DO NOT OPER
ATE THE GENERATOR IF ITS EXHAUST SYSTEM
IS LEAKING OR HAS BEEN DAMAGED. SYMP
TOMS OF CARBON MONOXIDE POISONING ARE
(A) INABILITY TO THINK COHERENTLY, (B)
VOMITTING, (C) TWITCHING MUSCLES, (D)
THROBBING TEMPLES, (E) DIZZINESS, (F)
HEADACHE, (G) WEAKNESS AND SLEEPINESS.
IF YOU FEEL ANY OF THESE SYMPTOMS, MOVE
INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS
PERSIST, GET MEDICAL HELP.
STARTING
IMPORT ANT: Read the vehicle manufacturer’s instruc
tions. The owner/operator should become familiar with
the vehicle in which this generator is installed. Differ
ences exist between vehicles. For example, some ve
hicles may use a transfer switch to isolate dockside
power from the generator, while other vehicles may use
an isolating receptacle. Some vehicles may be
equipped with a DC converter which allows the gener
ator to power certain DC lighting and other DC loads.
To crank and start the generator engine, proceed as
follows;
1. Turn CFF electrical loads, using whatever means
provided in your vehicle (such as a main line circuit
breaker or transfer switch.
NOTE: If you start the engine with start/stop switch on
the generator control panel, turn CFF loads by setting
the panel’s main breakers to their "CFF“ or “CPEN"
positions. Electrical load circuits will be turned CN after
the generator has started, stabilized and warmed up.
2. If you have not started the engine in more than two
weeks, press the Fuel Pump Primer switch and hold
it for about 30 seconds to activate the automatic
shut-off function. However, if the engine is warm,
skip Step 2.
3. To crank and start the engine, hold the start/stop
switch at START. Release the switch when the
engine starts.
CAUTION: If the engine does not start after it has
been cranking for 15 seconds, release the start/stop
switch and try again. Holding the switch for longer
than 15 seconds can damage the starter motor.
4. Let the engine run at no-load for a few minutes to
stabilize and warm up the engine.
5. Turn CN electrical loads, using whatever means
provided (such as a main circuit breaker or transfer
switch).
STOPPING THE GENERATOR
1. Turn CFF all electrical loads, using whatever
means provided (such a main circuit breaker or
transfer switch).
2. Let the generator run at no-load for a few minutes,
to stabilize internal engine-generator tempera
tures.
3. Press STCP on the start/stop switch. The engine
will come to complete stop.
APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator, ob
serve these guidelines:
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
• DC NCT overload the generator.
Letting Engine Stabilize: The generator supplies cor
rect rated frequency and voltage only at the proper
governed speed. Some electrical appliances may be
extremely sensitive to voltage and frequency. Incorrect
frequencies and/or voltages can damage those appli
ances.
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 CN electrical loads until after the generator
engine has started and stabilized CN-speed.
-7-
Do Not Overload the Generator: You can read the
rated wattage/amperage capacity of your generator on
the generator data plate (see 'Identification Record" on
Page 1).
Applying electrical loads in excess of the unit’s rated
capacity can bum out the unit and anything connected
to it. Also, overloading trips main circuit breakers.
To avoid overloading, add up the wattage of all con
nected electrical lighting, appliance, tool and motor
loads. This total should not be greater than the
generator’s rated wattage capacity.
• Most lighting, appliance, tool and motor loads indi
cate their reouired watts on their nameplate or data
plate. For light bulbs, simply note the wattage rating
of the bulb.
WATTAGE REFERENCE GUIDE
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
vehicie’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.
Rrst, figure the watts needed to start electric motors
in the system. To that figure, add the running
wattages of other items that will be operated by the
generator.
Do not apply heavy electrical loads for the first two
or three hours of operation.

This section discusses some of the engine protective
devices, overload protection and breaking in a new
generator.
AUTOMATIC LOW OIL PRESSURE
SHUTDOWN
The engine is equipped with a normally-closed (N.C.)
oil pressure switch (Figure 4). Engine oil pressure holds
the switch open during cranking and operation. Should
oil pressure drop below about 2-6 PSI, the switch con
tacts close and the engine automatcially shuts down.
Figure 4 — Switches for Enghe Safety Shutdown
ADDITIONAL INFORMATION
OVER VOLTAGE PROTECTION
A solid state voltage regulator (Rgure 6) controls the
generator’s AC output voltage. This regulator supplies
an excitation current to the rotor. By regulating the
rotor’s excitation current, the strength of its magnetic
field is regulated and, in turn, the voltage delivered to
connected electricaJ loads is controlled. When the AC
frequency is 60 Hz, voltage is regulated at 120 volts
(voltage-to-frequency ratio is 2-to-1).
HIGH TEMPERATURE SHUTDOWN
An oil temperature switch (Figure 4) with normally-open
(N.O.) contacts is mounted near the oil filter. If oil
temperature were to exceed about 284®F (140“C), the
switch contacts close and the engine shuts down.
FIELD BOOST
The Controller Circuit Board houses a field boost diode
and resistor which are not part of the automatic choke
circuit. These two components are part of a "field boost"
circuit (Figure 5). During engine cranking only, a posi
tive DC (battery) voltage is delivered through the diode,
resistor, brushes and slip rings, and to the generator
rotor. Application of this voltage to the rotor "flashes the
field’ whenever it is started. Hashing of the field each
time the generator starts makes sure that a sufficiently
strong magnetic field is available to produce the re
quired "pick up" voltage in the stator windings.
The voltage regulator also incorporates a "voltage surge
protection circuit." This circuit prevents troublesome
surges in the generator AC ou^ut voltage. Voltage
surge is a common cause of damage to electronic
equipment.
-9-
25-HOUR BREAK IN PERIOD
The first 25 hours of operation are for “breaking in" the
new generator. Correctly breaking in the generator is
essential to minimize fuel consumption and provide
maximum engine performance. During this 25-hour
break in period, comply with the following:
• Run the unit at varying electrical loads, to help seat
engine piston rings properly.
• For the 75 hours of operation after the “break in“
period, avoid light electrical loads. Load the gener?
ator at 50% (or more) of its rated wattage capacity.
Repeated light loads during the break in period can
cause improper seating of engine piston rings,
which could cause blowby and high oil consump
tion.
• During the break in period, check engine oil level
frequently. It is normal for oil consumption to be
high during the breaking in period.
• After the 25-hour break-in period, complete the
tasks recommended under “25-Hour Check Up.“
25-HOUR CHECK UP
After the 25-hour break-in period, contact an authorized
service facility for the following maintenance. The vehi
cle owner is responsible for any charges:
Change engine crankcase oil and oil filter.
Check all fluid levels.
Inspect cooling and ventilation openings on the
vehicle.
Check engine carburetor adjustments.
Check engine ignition system.
Inspect entire electrical system.
Inspect the engine exhaust system.
OPERATION IN HIGH GRASS OR BRUSH
Never operate the generator while the vehicle is parked
in high grass, weeds, brush or leaves. Such materials
can ignite and bum from the heat of the exhaust system.
The generator exhaust systern becomes extremely hot
during operation and remains hot for a long time after it
has shut down.

SPECIFICATIONS
FUEL REQUIREMENTS
The “Q“ series generator is equipped with a gasoline
fuel system as standard equipment. Specific installa
tions may provide either a separate fuel tank for the
generator, of the generator 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 arrange
ment causes the generator engine to “run out of gas“
while adequate fuel in the vehicle remains in the tank.
To 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.
CAUTION: Generac does not recommend using any
gasoline containing alcohol (such as “gasohor). If
you use any gasoline containing alcohol, it must not
contain more than 10 percent ethanol and It must be
removed from the tank during storage. Do NOT use
any gasoline containing methanol. If you use gas
oline with alcohol, Inspect more frequently for fuel
leaks and other abnormalities.
ENGINE OIL REQUIREMENTS
Use a high quality detergent oil classified "For Service
SF“ and with an oil viscosity rating of SAE 10W-30 oil.
Do not pour in any additives to the recommended oil.
Engine crankcase capacity is 1.5 U.S. quarts. See
MAINTENANCE section for oil level check and filling
procedures.

CHECKING ENGINE OIL LEVEL
Check engine crankcase oil level at least every eight
hours of operation, or before you use it (Figure 7).
Figure 8 — Location of Oil Drain Plug
• Remove oil dipstick and fill crankcase with the rec
ommended oil (See Page 11). The engine crank
case can hold about 1.7 liters. DO NOT OVERFILL
ABOVE "FULL" MARK.
• Install and tighten dipstick cap before operating
engine.
Figure 7 — Oil Dipstick and Fill Tube
• Be sure the generator is as level as possible.
• Remove oil dipstick and wipe dry with clean, lint-free
cloth.
• Install and tighten oil dipstick, then remove again.
• Oil should be at dipstick FULL mark. If necessary,
add the recommended oil to the FULL mark only.
DO NOT OVERFILL ABOVE “FULL" MARK.
• Install and tighten oil dipstick cap before operating
the engine.
NOTE: See "Engine Oil Requirements" on Page 11 for
recommended oils.
CHANGE ENGINE OIL
Change engine oil after the first 25 hours of operation
(after the 25-hour break-in period. Page 10). Thereaf
ter, change oil every 50 operating hours. Change oil
more frequently if operating consistently under heavy
load or at high ambient temperatures.
• Warm up engine for at least five minutes, then shut
down.
• With engine still warm from running, remove oil
drain plug (Figure 8). Drain oil completely into a
suitable container.
• When oil has drained, install and tighten oil drain
plug.
CHANGE OIL FILTER
Replace the engine oil filter after the first 25 hours of
operation, every 100 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 9).
• Coat gasket of new filter with engine oil.
• Turn new filter clockwise until its gasket contacts
tightly with the filter adapter. Then tighten with an
additional 3/4 to one turn by hand.
• Run engine and check for leaks.
-72-
ENGINE AIR CLEANER
Clean and re-oil the foam pre-cleaner every three
months or every 25 hours of operation; whichever oc
curs first. Sen/ice the foam pre^eaner more frequentiy
if you operate the generator in extremely dusty or dirty
conditions (Figure 10):
• Turn KNOB counterclockwise to loosen.
• Remove COVER, FOAM PRE-CLEANER and
PAPER RLTER.
• Remove foam pre-cleaner from cover.
• Wash foam pre-cleaner in liquid detergent and
water.
• Wrap foam pre-cleaner in a cloth and squeeze dry.
• Saturate foam pre-cleaner in engine oil. Squeeze
to remove excess oil and to distribute oil.
• Install foam pre-cleaner into cover, followed by
filter. Tabs at edges of paper filter must lock
ots on cover.
K
• Insert bottom locking tag of cover into slot. Install
cover, foam pre-cleaner and paper filter.
Once each year or every 100 operating hours (which
ever comes first), replace the paper filter. The new
replacement filter must be a flame retardent type.
Figure 11 — Areas to Clean on Air Intake Screen
ENGINE SPARK PLUGS
Clean engine spark plugs and reset gap to 0.030 inch
(0.8mm) every 100 hours of operation (Figure 12).
Clean by scraping or wire brushing and washing with
commercial solvent DO NOT BLAST CLEAN SPARK
PLUGS.
CAUTION: Sparking can occur If wire terminals do
not fit firmly over spark plug terminal ends. If nec
essary, reform wire terminals to obtain a tight fit.
Figure 10 — Engine Air Cleaner
CLEAN AIR INTAKE SCREEN
Clean all foreign material from the air intake screen
(Rgure 11) at least once every 100 hours of operation.

MISCELLANEOUS MAINTENANCE
SPARK ARRESTOR MUFFLERS
If the generator is not equipped with a spark arrestor
exhaust muffler and is to be used on any forest covered,
brush covered or grass covered unimproved land, you
may have to install a spark arrestor. The spark arrestor
must be maintained in effective working order by the
vehicle owner/operator.
For assistance in ordering, installing and maintaining
spark arrestor exhaust mufflers, contact your nearest
authorized service facility.
Exhaust mufflers supplied by Generac are spark arres
tor types. Generac exhaust mufflers for RV 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 muffler and run engine for about 15 minutes.
Shut engine down, let the muffler cool and install the
plug.
WARNING: BE SURE TO RE-INSTALL THE PLUG
FROM THE MUFFLER TIGHTLY. ENGINE VIBRA
TION COULD CAUSE A LOOSE PLUG TO FALL
OUT. WITHOUT THE PLUG IN PLACE, HOT EN
GINE EXHAUST IS DIRECTED OUT THE OPEN
ING. THIS HOT EXHAUST, DEPENDING ON THE
INSTALLATION, COULD BE DIRECTED TO
AREAS NOT ABLE TO WITHSTAND THE EX
TREME HEAT SUCH AS WOODEN FLOOR
BOARDS OR OTHER FLAMMABLE MATERIALS.
THIS COULD RESULT IN A FIRE.
CLEANING THE GENERATOR
Keep your generator set as clean and dry as possible.
Dirt and moisture that are permitted to accumuiate on
electrical windings have an adverse affect on the insu
lation resistance of those windings.
Moisture that is allowed to remain in contact with wind
ings will be retained in voids and cracks of the windings.
Dirt makes the problem worse, since it tends to hold the
moisture into contact with the windings. Salt, as from
sea air, worsens the problem since it tends to absorb
moisture from the air. The combination of salt and
moisture makes a good electrical conductor.
CAUTION! Do NOT use a forceful spray of water to
clean the generator. Water will enter the generator
Interior and cause problems, and may also contam
inate the generator fuel system.
All lead-acid storage batteries will discharge when not
in use. The generator battery should be inspected as
follows:
Once Weekly: Inspect battery posts and cables for
tightness, corrosion. Clean and/or tighten as needed.
Also check battery fluid level, and, if necessary, fill with
DISTILLED WATER ONLY. DO NOT USE TAP
WATER IN BATTERY.
Every Six Months: Have battery state of charge and
condition checked by automotive service facility. This
should be done with automotive type battery hydrome
ter.
DANGER: STORAGE BATTERIES GIVE OFF EX
PLOSIVE HYDROGEN GAS. THIS GAS CAN
FORM AN EXPLOSIVE MIXTURE AROUND THE
BATTERY FOR SEVERAL HOURS AFTER
CHARGING. THE SLIGHTEST SPARK CAN IG
NITE THE GAS AND CAUSE AN EXPLOSION.
SUCH AN EXPLOSION CAN SHATTER THE BAT
TERY AND CAUSE BLINDNESS OR OTHER IN
JURY. 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.
DANGER: BATTERY ELECTROLYTE FLUID IS
AN EXTREMELY CAUSTIC SULFURIC ACID SO
LUTION THAT CAN CAUSE SEVERE BURNS. DO
NOT PERMIT FLUID TO CONTACT EYES, SKIN,
CLOTHING, PAINTED SURFACES, ETC. WEAR
PROTECTIVE GOGGLES, PROTECTIVE CLOTH
ING AND GLOVES WHEN HANDLING A BAT
TERY. IF YOU SPILL THE FLUID, FLUSH THE
AFFECTED AREA IMMEDIATELY WITH CLEAR
WATER.
DANGER: DO NOT USE ANY JUMPER CABLES
OR BOOSTER BATTERY TO CRANK AND START
THE GENERATOR ENGINE. IF ANY BATTERY
HAS DISCHARGED, REMOVE IT FROM THE VE
HICLE FOR RECHARGING.
To obtain a sen/ice manual for your generator, order it
from your dealer/distributor or contact the factory. Be
sure to identify your MODEL NUMBER and SERIES.

MAJOR SERVICE MANUAL
-14-
DRIVE BELTS
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. The drive train, drive
belt and pulleys are warranted for the life of the gener
ator. Drive belt tension was properly adjusted before
the unit was shipped from the factory. If you suspect
that drive belt tension is incorrect, contact an authorized
service facility.
Remove spark plugs and pour about two or three
tablespoons of clean, fresh, engine oil into spark
plug threaded openings. Crank engine several
times to distribute oil, then install and tighten spark
plugs.
Remove the battery and store in a cool, dry room
on a wooden board. Never store the battery on any
concrete or wooden floor.
Clean and wipe the entire generator.
EXERCISING THE GENERATOR
Generac recommends that you start and operate the
generator at least once every seven days. Let the unit
run for at least 30 minutes to "exercise” the engine.
OUT OF SERVICE PROTECTION
If you cannot exercise the generator every seven days
and it is to be out of service longer than 30 days, prepare
the.generator for storage as follows:
• Start the engine and let it warm up.
• Close the fuel shutoff valve in the fuel supply line
and let the engine “run out of gas."
• While the engine is still warm from running, drain
the oil completely. Refill crankcase with SAE10W30 oil having API classification "For Service SF."
• Attach a tag to the engine indicating the viscosity
and classification of the oil in the crankcase.
RETURN THE UNIT TO SERVICE AFTER
STORAGE
To return the unit to service after storage, proceed as
follows:
• Check tag on engine for oil viscosity and classifica
tion. Verify that the correct recommended oil is
used in engine. If necessary, drain and refill with
proper oil.
• Check battery. Fill all cells to the proper level with
distilled water. DO NOT USE TAP WATER IN THE
BATTERY. Recharge battery to 100% state of
charge, or, if defective, replace the battery.
• Turn OFF all electrical loads, add gasoline if neces
sary; then start the engine.
• Let engine warm up.
• Apply electrical loads to at least 50% of the unit’s
rated wattage capacity.
• When engine is thoroughly warmed up, shut it
down.
THE GENERATOR IS NOW READY FOR SERVICE.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board ("CARB") and Generac Corporation are pleased to explain the Emission Control System
Warranty on your new recreational vehicle generator 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 Corporation will
warrant the emission control system on your recreational vehicle for the periods of time listed below provided there has
been no abuse, neglect, unapproved modification, or improper maintenance of your recreational vehicle generator engine.
Your emission control system may include parts such as the carburetor, ignition system and exhaust system. Also included
may be the compression release system and other emission-related assemblies.
Where a warrantable condition exists, Generac Corporation will repair your recreational vehicle generator engine at no cost
to you for diagnosis, parts and labor.
MANUFACTURER'S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
Emissions control systems on 1995 and later model year recreational vehicle generator engines are warranted for two years
as hereinafter noted. If, during such warranty period, any emission-related part on your engine is defective in materials or
workmanship, the part will be repaired or replaced by Generac Corporation.
OWNER'S WARRANTY RESPONSIBILITIES:
As the recreational vehicle generator engine owner, you are responsible for the performance of the required maintenance
listed in your owners manual. Generac Corporation recommends that you retain all receipts covering maintenance on your
recreational vehicle generator engine, but Generac Corporation will not deny warranty solely due to the lack of receipts or
for your failure to provide written evidence of the performance of all scheduled maintenance.
As the recreational vehicle generator engine owner, you should, however, be aware that Generac Corporation may deny
you warranty coverage if your recreational vehicle generator engine or a part thereof has failed due to abuse, neglect,
improper maintenance or unapproved modifications.
You are responsible for presenting your recreational vehicle engine to a Generac Corporation Authorized Service Outlet as
soon as a problem exists. 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 a Generac Corporation Authorized Service Outlet or by contacting
Generac Corporation at;
GENERAC CORPORATION PH: (414) 544-4811
P.O.BOX8 FX:(414)544-0179
WAUKESHA,Wl 53187
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 Corporation pursuant to California law. See also the
Generac Corporation Limited Warranties for Generac Corporation which is enclosed herewith on a separate sheet and also is
provided to you by Generac Corporation. The ECS Warranty applies only to the emission control system of your new engine.
To the extent that there is any conflict in terms between the ECS Warranty and the Generac Corporation Warranty, the ECS
Warranty shall apply except in any circumstances in which the Generac Corporation Warranty may provide a longer warranty
period. Both the ECS Warranty and the Generac Corporation Warranty describe important rights and obligations with
respect to your new engine.
Warranty service can only be performed by a Generac Corporation Authorized Service Outlet. At the time of requesting
warranty service, evidence must be presented of the date of the sale to the original purchaser. The purchaser shall pay any
charges for making service calls and/or for transporting the products to and from the place where the inspection and/or war
ranty work is.performed. The purchaser shall be responsible for any damage or loss incurred in connection with the trans
portation of any engine or any part(s) thereof submitted for inspection and/or warranty work.
IF YOU HAVE ANY QUESTIONS REGARDING YOUR WARRANTY RIGHTS AND RESPONSIBILITIES, YOU SHOULD CONTACT
GENERAC CORPORATION AT 1-800-526-2871
EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty ("ECS Warranty") for 1995 and Later Model Year recreational vehicle generator Engines:
A. Applicability: This warranty shall apply to 1995 and later model year recreational vehicle generator engines. The ECS
Warranty Period ("ECS Warranty Period") shall begin on the date the new engine or equipment is delivered to its original,
end-use purchaser and shall continue for 24 consecutive months thereafter.
B. General Emissions Warranty Coverage: Generac Corporation warrants to the original, end-use purchaser of the new engine
or equipment and to each subsequent purchaser that each of its recreational vehicle generator engines is:
1. Designed, built and equipped so as to conform with all applicable regulations adopted by the Air Resources Board pur
suant to its authority, and
2. Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, will cause a warrant
ed emissions - related part to fail to be identical in all material respects to the part as described in the engine manufac
turer'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 which 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 Corporation according to Subsection (4) below. Any such part repaired or replaced under
the ECS Warranty shall be warranted for any remainder of the ECS Warranty Period.
2. Any warranted, emissions-related part which 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 any remainder of the ECS Warranty Period.
3. Any warranted, emissions-related part which 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 Corporation 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 Corporation Authorized Service Outlet.
5. The owner shall not be charged for diagnostic labor which leads to the determination that a part covered by the ECS
Warranty is in fact defective, provided that such diagnostic work is performed at a Generac Corporation Authorized
Service Outlet.
6. Generac Corporation shall be liable for damages to other original engine components or approved modifications proxi-
mately 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 Corporation 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 Corporation ECS warranty obligations.
9. Unapproved add-on modified parts may not be used to modify or repair a Generac Corporation engine. Such use voids
this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim. Generac Corporation shall not
be liable hereunder for failures of any warranted parts of a Generac Corporation engine caused by the use of such an
unapproved add-on or modified part.
