WARNING:
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
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.
GENERAL HAZARDS
• For safety reasons, the manufacturer recommends
that the installation, initial start-up and maintenance of this equipment is carried out by an
Authorized Service Dealer.
• The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death.
Never operate the generator set with the vehicle
inside any garage or other enclosed area. DO NOT
OPERATE THE GENERATOR IF THE EXHAUST
SYSTEM IS LEAKING OR HAS BEEN DAMAGED.
SYMPTOMS OF CARBON MONOXIDE POISONING
ARE (a) inability to think coherently, (b) nausea,
(c) vomiting, (d) twitching muscles, (e) throbbing
temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF EXPERIENCING ANY
OF THESE SYMPTOMS, MOVE INTO FRESH AIR
IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Shut down the generator and
do not operate it until it has been inspected and
repaired.
• Never sleep in the vehicle while the genset is run-
ning unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation
manual. Make sure there is ample fresh air when
operating the genset in a confined area.
• 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 ven-
tilating 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
permit 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
physically or mentally fatigued.
• Inspect the generator regularly, and contact the
nearest Authorized Service Dealer immediately for
parts needing repair or replacement.
2
• Before performing any maintenance on the generator, 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 conditions 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, terminals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards and barriers
are in 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.
• During installation onto the vehicle, have the
generator 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 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 American Wire
Gauge (AWG) copper wire minimum.
• In case of accident caused by electric shock, immediately 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.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.
Safety Rules
Recreational Vehicle Generators
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 installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
• Keep a fire extinguisher in the vehicle at all times.
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 there are any questions
pertaining to fire extinguishers, consult the local
fire department.
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surrounding the generator clean and free from debris.
• Gasoline is extremely FLAMMABLE and its vapors
are EXPLOSIVE. Do not permit smoking, open
flame, sparks or any source of heat in the vicinity
while handling gasoline. Comply with all laws governing 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.

1.1 GENERATOR IDENTIFICATION
Please record the following information from the generator DATA DECAL or information decal.
1. Model Number _____________________ 2. Serial Number __________________
3. kW Rating _________________________ 4. Rated Voltage __________________
These generators have been designed and manufactured for supplying electrical power for recreational
vehicles. DO 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
advised by competent authority.
For fire safety, the generator must have been
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 instructions.
After installation, do nothing that might render
the unit in noncompliance with such codes, standards and instructions.
Use the generator set to supply electrical power for
operating one of the following electrical loads:
• QUIETPACT 55G & LP: 120 and/or 240 volts,
single phase, 60 Hz electrical loads. These loads
can require up to 5500 watts (5.5 kW) of total
power, but cannot exceed 45.8 AC amperes of current at 120 volts or exceed 22.9 AC amperes at 240
volts.
• QUIETPACT 65G & LP: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can
require up to 6500 watts (6.5 kW) of total power,
but cannot exceed 54.1 AC amperes of current at
120 volts or exceed 27 AC amperes at 240 volts.
• QUIETPACT 75G & LP: 120 and/or 240 volts,
single phase, 60 Hz electrical loads. These loads
can require up to 7500 watts (7.5 kW) of total
power, but cannot exceed 62.5 AC amperes of current at 120 volts or exceed 31.2 AC amperes at 240
volts.
Do not overload the generator. Some installa-
tions may require that electrical loads be alternated to avoid overloading. Applying excessively high electrical loads may damage the
generator 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 current) for starting than for continuous operation.
DANGER
1.3 INSTALLATION
This Owner’s Manual has been prepared under the
assumption that a competent, qualified technician
installed the generator into a recreational vehicle. We
also assume the installer complied with all applicable
codes, standards and regulations pertaining to installation.
An INSTALLATION MANUAL was shipped with the
generator. That Manual contains manufacturer’s
instructions and recommendations for installing
the unit into an industrial vehicle. After installation,
installers should forward 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.
1.4 SAFETY
Before using the generator set, carefully read
GENERAL SAFETY RULES inside the cover. Comply
with these RULES to prevent accidents and damage
to equipment and/or property. The manufacturer
suggests copying and posting the GENERAL SAFETY
RULES to potential operators of this equipment.
1.5 GENERATOR AC CONNECTION
SYSTEM
These air-cooled 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.
Generators may be installed to provide the following
outputs:
1. 120 VAC loads only — one load with a maximum
total wattage requirement equal to the generator’s
rated power output (in watts), and 120V across
the generator output terminals. Figure 1.1 shows
the generator lead wire connections for 120VAC
ONLY.
2. 120/240 VAC loads — one load with a maximum
total wattage requirement equal to the generator’s
rated power output, and 240V across the generator output terminals; or two seperate loads, each
with a maximum total wattage requirement equal
to half of the generator’s rated power output (in
watts), and 120V across the generator output terminals. Figure 1.2, shows the generator lead wire
connections for 120/240 VAC loads. Also refer to
section 2.1.4 Line Breakers for circuit breaker
ratings.
This procedure should be done by an Authorized
Service Dealer or other qualified installer.

1.6 SPECIFICATIONS
1.6.1 FUEL REQUIREMENTS (GASOLINE)
This generator is equipped with a gasoline fuel system
as standard equipment. Specific installations may
provide either a separate fuel tank for the generator,
or the generator may “share” the vehicle engine’s fuel
tank.
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.
To reduce lead and carbon deposits use high quality UNLEADED gasoline with the generator. Leaded
REGULAR grade gasoline is an acceptable substitute.
6
NOTE:
Using unleaded gasoline contributes to longer
engine valve life by reducing lead and carbon
deposits.
The manufacturer does not recommend using
any gasoline containing alcohol (such as “gasohol”). If using 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 using gasoline with alcohol, inspect
more frequently for fuel leaks and other abnormalities.
1.6.2 ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with American
Petroleum Institued (API) Classification SF, SG, SH or
SJ. The recommended oil viscosity weights include
the following:
• During summer months (40 deg. F and higher),
SAE 30 or SAE 10W-30
• During winter months (40 deg. F to -20 deg. F),
SAE 5W-30 or SAE5W20
• DO NOT USE SAE 10W-40
Crankcase and oil filter capacity is approximately 1.8
L or 1.9 U.S. quarts. DO NOT use special additives.

2.3 AUTOMATIC 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.
2.4 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 INSTALLATION
Generator installation must have been properly completed so it complies with all applicable codes, standards and regulations and with the manufacturer's
recommendations.
2.4.2 ENGINE LUBRICATION
Have the engine crankcase properly serviced with the
recommended oil before starting. Refer to Section
1.6.3 and Sections 3.1 and 3.2 for oil servicing procedures and recommendations.
Any attempt to crank or start the engine before
it has been properly serviced it with the recommended oil may result in an engine failure.
2.4.3 FUEL SUPPLY
The engine must have an adequate supply of proper
fuel to operate. Before starting it, check that sufficient fuel is available.
NOTE:
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
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 temperatures, 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.
8
Air inlet and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. Without sufficient cooling
and ventilating airflow, the engine/generator quickly
overheats, which causes it to shut down and may
damage the generator.
2.4.5 ENGINE EXHAUST GAS
Before starting the generator engine, be sure there is
no way for exhaust gases to enter the vehicle interior
and endanger people or animals. Close windows,
doors and other openings in the vehicle that, if open,
might permit exhaust gases to enter the vehicle.
Section 2 – Operation
Recreational Vehicle Generators
DANGER
The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOXIDE
POISONING ARE (a) inability to think coherently, (b) nausea, (c) vomiting, (d) twitching
muscles, (e) throbbing temples, (f) dizziness,
(g) headaches, (h) weakness, and (i) sleepiness.
IF EXPERIENCING ANY OF THESE SYMPTOMS,
MOVE INTO FRESH AIR IMMEDIATELY. IF
SYMPTOMS PERSIST, GET MEDICAL HELP. Shut
down the generator and do not operate it until
it has been inspected and repaired.
DANGER
Never sleep in the vehicle while the genset is
running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation manual. Make sure there is ample fresh air
when operating the genset in a confined area.
2.5 STARTING THE GENERATOR
NOTE:
Read the vehicle manufacturer’s instructions.
The owner/operator should become familiar with
the vehicle in which this generator is installed.
Differences exist between vehicles. For example,
some vehicles 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 generator to power certain DC
lighting and other DC loads.
To crank and start the generator engine, proceed as
follows:
1. Turn OFF electrical loads using the means pro-
vided in the vehicle (such as a main line circuit
breaker or transfer switch).
NOTE:
If starting from the generator control panel, turn
OFF loads by setting the generator’s main circuit
breaker to the OFF (or open) position. If starting
from a remote panel, turn OFF loads using the
means provided in the vehicle (such as a main
circuit breaker). Electrical load circuits will be
turned ON after the generator has started, stabilized and warmed up.
2. If the engine has not been started in more than
two weeks, press the Fuel Pump Primer switch
and hold it for about 10 seconds. 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.
If the engine does not start after it has been
cranking for 15 seconds, release the Start/Stop
switch and wait 1 minute before trying 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.
5. Turn ON electrical loads using the means provided (such as a main circuit breaker or 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.
The engine will come to a complete stop.
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 appliances 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 sufficient 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.
9
Section 2 – Operation
Recreational Vehicle Generators
2.7.2 DO NOT OVERLOAD THE GENERATOR
Read the rated wattage/amperage capacity of the generator on the generator data decal (see Section 1.1).
Applying electrical loads in excess of the unit’s rated
capacity will cause the engine/generator to automatically shut down.
To avoid overloading, add up the wattage of all connected 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
indicate their required watts on their nameplate or
data plate. For light bulbs, simply note the wattage
rating of the bulb.
• 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. First, 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.
2.8 PROTECTION SYSTEMS
2.8.1 LOW OIL PRESSURE SWITCH
This switch (Figure 2.3) has normally closed (N.C.)
contacts 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 270º F (132º C) for gasoline models,
and 284° F (140° C) for LP models, initiating an
engine shutdown.
Figure 2.3 – Low Oil Pressure and
High Temperature Switches
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 delivered through a diode, resistor, brushes, 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.
10
Figure 2.4 – Field Boost Circuit
2.8.4 OVERVOLTAGE PROTECTION
A solid-state voltage regulator (Figure 2.5) 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 electrical loads is controlled.
When the AC frequency is 60 Hertz, voltage is regulated at 115 volts.
Figure 2.5 – Solid State Voltage Regulator
The voltage regulator also incorporates a “voltage
surge protection circuit.” This circuit prevents troublesome surges in the generator AC output voltage.
Voltage surge is a common cause of damage to electronic equipment.
2.8.5 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
provide maximum engine performance. During this
25-hour 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 piston
rings, resulting in blowby and high oil consumption.
• After operating the unit for 25 hours, complete the
tasks recommended under Section 2.8.6.
Section 3 – Maintenance
Recreational Vehicle Generators
2.8.6 25-HOUR CHECK-UP
After the 25-hour break-in period, contact an
Authorized Service Dealer for the following maintenance. (The vehicle owner is responsible for any
charges relating to normal unit maintenance.)
• Change the engine crankcase oil and oil filter.
• Check all fluid levels.
• Inspect the cooling and ventilation openings.
• Check the engine ignition system.
• Inspect the entire electrical system.
• Inspect the engine exhaust system.
2.8.7 OPERATION IN HIGH GRASS
OR BRUSH
Never operate the generator while the vehicle
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 during 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. Check the engine
crankcase oil level at least every eight hours of operation, or before it is used. 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
“Full” mark.
4. If necessary, remove the oil fill cap on the rocker
cover and slowly add oil until it reaches the dipstick “Full” mark. DO NOT FILL ABOVE THE
“FULL” MARK.
Never operate the engine with the oil level
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.
11
Section 3 – Maintenance
Recreational Vehicle Generators
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 2.8.5). Thereafter, change the oil every 100
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 thereafter.
To change the oil and/or oil filter, 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.
Figure 3.1 — Oil Dipstick/Fill Tube and
Location of Oil Drain Plug
Oil Dipstick
9. Start the engine and check for leaks.
Figure 3.2 — Engine Oil Filter
NOTE:
Check the oil level and fill to the “FULL” mark after
checking for leaks. The filter will retain some oil.
3.3 MAINTAINING THE ENGINE
Oil Drain Hose
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
gasket of the new filter.
6. 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.
7. Remove the dipstick and fill crankcase with the
proper type and amount of recommended oil
(see Section 1.6.2). The engine crankcase can
hold about 1.8 liters or 1.9 quarts with oil filter change. DO NOT FILL ABOVE THE “FULL”
MARK.
8. Install and tighten the dipstick before operating
the engine.

AIR CLEANER
3.3.1 CLEANING THE FOAM PRECLEANER
Clean and re-oil the foam precleaner every three
months or every 25 hours of operation, whichever
occurs first. Service the foam precleaner more frequently if operating the generator in extremely dusty
or dirty conditions. Use the following procedure
(Figure 3.3):
1. Turn the knob counterclockwise to loosen.
2. Remove the cover, foam precleaner and paper
filter.
3. Remove the foam precleaner from the cover.
4. Wash the foam precleaner in liquid detergent and
water.
5. Wrap the foam precleaner in a clean cloth and
gently squeeze it dry.
6. Saturate the foam precleaner in clean engine
oil. Gently squeeze it in a clean cloth to remove
excess oil and to distribute oil (DO NOT TWIST).
7. Install the foam precleaner into the cover, followed by the paper filter. Tabs at edges of paper
filter must lock into slots on cover.
8. Install the cover, foam precleaner and paper filter.
9. Replace knob to retain the filter in place.

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
to clean.
2. Remove the spark plug and check the condition.
Replace the spark plug if worn or if reuse is questionable.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.030 inch (0.76 mm)
by carefully bending the ground electrode (Figure
3.4).

3.6 CLEAN SPARK ARRESTOR
The engine exhaust muffler has a spark arrestor
screen. Inspect and clean the screen every 50 hours
of operation or once each year, whichever comes
first.
NOTE:
If using the generator on any forest-covered,
brush-covered or grass-covered unimproved land,
it must equipped with a spark arrestor. The spark
arrestor must be maintained in good condition by
the owner/operator.
Clean and inspect the spark arrestor as follows:
• Remove the screen retaining bracket by removing
the screw.
• Slide the spark arrestor screen out from the tail
pipe.
• Inspect screen and replace if torn, perforated or
otherwise damaged. DO NOT USE a defective
screen. If screen is not damaged, clean it with commercial solvent.
• Replace the screen and the retaining bracket.

3.7 CLEANING THE GENERATOR
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and moisture 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 which is detrimental to the generator.
Do NOT use a forceful spray of water to clean
the generator. Water will enter the generator
interior and cause problems, and may also contaminate the generator fuel system.
3.8 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in
use. The generator battery should be inspected as
follows:
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batteries give off explosive hydrogen gas. This gas can
form an explosive mixture around the battery
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 body before touching the battery by
first touching a grounded metal surface.
A battery presents a risk of electrical shock
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.
3.8.1 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.
3.8.2 EVERY SIX MONTHS
• Have the state of charge and condition checked.
This should be done with an automotive-type battery hydrometer.
NOTE:
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush
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 bicarbonate 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.

3.9 MAJOR SERVICE MANUAL
To obtain a service manual for the generator, contact
the nearest Authorized Service Dealer. Make sure to
identify the MODEL NUMBER and SERIES. Manuals
can be obtained from the internet website or a service
dealer.
3.10 DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. Drive belt tension
was properly adjusted before the unit was shipped
from the factory. If suspect that drive belt tension is
incorrect, contact an Authorized Service Dealer.
3.11 EXERCISING THE GENERATOR
The manufacturer recommends starting and operating the generator at least once every seven days. Let
the unit run for at least 30 minutes to “exercise” the
engine.
3.12 OUT OF SERVICE PROCEDURE
3.12.1 REMOVAL FROM SERVICE
If the generator cannot be exercised every seven days,
and it is to be out of service longer than 30 days, prepare the generator for storage as follows:
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line
and allow the unit to shut down.
3. While the engine is still warm from running, drain
the oil completely. Refill the crankcase with SAE
5W-30 oil having API classification “For Service
SF.”
4. Attach a tag to the engine indicating the viscosity
and classification of the oil in the crankcase.
5. Remove the spark plug and pour two or three
tablespoons of clean, fresh engine oil into the
spark plug threaded openings. Reinstall and
tighten the spark plug.
6. Remove the battery and store it in a cool, dry
room on a wooden board. Never store the battery
on any concrete or earthen floor.
7. Clean and wipe the entire generator.
Section 3 – Maintenance
Recreational Vehicle Generators
3.12.2 RETURN TO SERVICE
To return the unit to service after storage, proceed
as follows:
1. Check the tag on the engine for oil viscosity and
classification. Verify that the correct recommended oil is used in the engine (see Section 1.5.4). If
necessary, drain and refill with the proper oil.
2. Check the state of the battery. Fill all cells of
unsealed batteries to the proper level with distilled water. DO NOT USE TAP WATER IN THE
BATTERY. Recharge the battery to 100 percent
state of charge, or, if defective, replace the battery.
3. Clean and wipe the entire generator.
4. Reconnect the battery. Observe battery polarity.
Damage may occur if the battery is connected
incorrectly.
5. Turn OFF all electrical loads. Add fuel if necessary and then start the engine.
6. Allow the unit to warm up thoroughly.
7. Apply electrical loads to at least 50 percent of the
