Safety Rules
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.
The engine exhaust from this product
•
contains chemicals known to the state
defects or other reproductive harm.
This product contains or emits chemicals
•
known to the state of California to cause
cancer, birth defects or other reproductive harm.
Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become
familiar with this manual and with the unit. The generator can operate safely, efficiently and reliably only
if it is properly installed, operated and maintained.
Many accidents are caused by failing to follow simple
and fundamental rules or precautions.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed
to the unit, are, therefore, not all-inclusive. If using
a procedure, work method or operating technique
the manufacturer does not specifically recommend,
ensurethat it is safe for others. Also make sure the
procedure, work method or operating technique utlized does not render the generator unsafe.
WARNING:•
of California to cause cancer, birth
WARNING:•
DANGER
Despite the safe design of this generator, operat-
ing 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.
The engine exhaust fumes contain carbon mon-
•
oxide, which can be DEADLY. This dangerous
gas, if breathed in sufficient concentrations, can
cause unconsciousness or even death. Thus, the
exhaust system must be installed properly, in strict
compliance with applicable codes and standards.
Following installation, do nothing that might render the system unsafe or in noncompliance with
such codes and standards. The generator compartment must be completely vapor-sealed from
the vehicle interior. There must be no possibility of
exhaust fumes entering the vehicle interior. 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.
2
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.
Before performing any maintenance on the gen-
•
erator, disconnect its battery cables to prevent
accidental start up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
Never use the generator or any of its parts as a
•
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating 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, 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
Safety Rules
Recreational Vehicle Generator
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 equip-
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.
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.

Section 1 – General Information
Recreational Vehicle Generator
1.2 GENERATOR APPLICABILITY
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 a 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 this generator to supply electrical power for
operating 120/240-volt, single-phase, 60 Hertz, AC
electrical loads. These loads can require up to 4,800
watts (4.8 kW) of power, but cannot exceed 40 AC
amperes of current at 120 volts, or 20 AC amperes
at 240 volts for model 02010-2. For model 04164-3,
the loads can require up to 4,500 watts (4.5 kW) of
power, but cannot exceed 37.5 amperes of current at
120 volts, or 18.8 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 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 suggest copying and posting the “Safety Rules” in potential hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
1.4 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.
The generator may have been installed so that it powers 120-volt AC loads (Figure 1.1). It can be wired to
connect both 120- and/or 240-volt AC electrical loads.
This procedure should be done by an Authorized
Service Dealer or other qualified installer.
Figure 1.1 – Connections for 120 Volts Only
1.5 SPECIFICATIONS
1.5.1 FUEL REQUIREMENTS
This generator is equipped with a gasoline fuel system. 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.
To reduce lead and carbon deposits use high quality UNLEADED gasoline with the generator. Leaded
REGULAR grade gasoline is an acceptable substitute.
NOTE:
Using unleaded gasoline contributes to longer
engine valve life by reducing lead and carbon
deposits.
5
Section 1 – General Information
Recreational Vehicle Generator
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.
1.5.2 OPTIONAL PROPANE FUEL SYSTEM
This generator is equipped with a liquid propane (LP)
gas fuel system. LP gas is usually supplied as a liquid
in pressure tanks.
The generator requires a vapor withdrawal type fuel
system. This type of gaseous fuel system uses the
vapors forming above the liquid fuel in the storage
tank. Air temperature around the storage tank must
be high enough to sustain adequate fuel vaporization.
In colder climates, it may be necessary to use an independent heat source to be sure the fuel sufficiently
vaporizes in the storage tank.
LP gas may consist of propane, butane or a mixture of
the two gases. Propane vaporizes at temperatures as
low as -20° F (-29° C), but butane returns to its liquid
state when the temperature drops below about 32° F
(0° C). For that reason, a higher ratio of propane is
desired in the gas mixture when temperatures drop
below freezing.
1.5.3 FUEL CONSUMPTION
Model No Load 1/2 Load Full Load
02010-2 0.32 0.46 0.76
04164-3 0.47/17.05 0.72/3.06 1.25/45.35
Gasoline is in gal/h.
LP is in gal/h and cf/h.
1.5.4 ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with American
Petroleum Institute (API) Service Classification SF,
SG or SH. The recommended oil weights include the
following:
During summer months: SAE 30. An acceptable
•
substitute is SAE 10W-30.
During winter months: SAE 5W-30. DO NOT USE
•
SAE 10-W40.
Crankcase and oil filter capacity is approximately
1,400 mL or 1.5 U.S. quarts. Do NOT use special
additives. See "Checking the Engine Oil Level" and
"Changing the Engine Oil and/or Oil Filter" sections
for oil level check and fill procedures.

Section 2 – Operation
Recreational Vehicle Generator
2.1 GENERATOR CONTROL PANEL
The following features are mounted on the generator
control panel (Figure 2.1):
Figure 2.1 – Generator Control Panel
2.1.1 FUEL PRIMER
Before starting a cold engine (if it has not been started
in more than two weeks), this switch must be pressed
for approximately 10 to 15 seconds to bring fuel from
the tank to the carburetor. This rocker type switch
springs back into its original position when released.
It is not necessary to press the primer switch for LP
units.
NOTE:
If the generator has been reconnected for dual voltage AC output (120/240 volts), install line breakers having an amperage rating that is different
than that stated in the "Generator AC Connection
System" section. The replacement line breakers
consist of two separate breakers (one 20 amp, and
one 30 amp) with a connecting 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.
2.2 OPTIONAL REMOTE
START/STOP PANEL
A remote mounted Start/Stop Panel (Figure 2.2) is
available that allows starting and stopping the generator engine conveniently from inside the vehicle.
The remote panel includes a Start/Stop switch, hourmeter, generator run lamp and a wire harness.
Figure 2.2 — Optional Remote Panel
(Models 004057 and 004184)
2.1.2 START/STOP SWITCH
To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in the STOP position until the engine shuts
off. The switch center position is the RUN position.
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 the fuse must be replaxed, 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 120/240-volt AC output
to the vehicle circuits. The generator has one 20-amp
breaker and one 30-amp breaker.
2.3 AUTOMATIC CHOKE
The 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 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.

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.
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
Any attempt to crank or start the engine before
it hase been properly serviced 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
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.
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 start the generator from either the generator control panel or from the optional remote panel, 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).
8
Section 2 – Operation
Recreational Vehicle Generator
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 to 15 seconds to prime
the fuel system. However, if the engine is warm,
skip Step 2.
3. Hold the engine Start/Stop switch in the START
position to crank the engine. 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 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.
5. Turn ON electrical loads using the means provided (such as a main circuit breaker or transfer
switch).
2.8 SUMMER/WINTER HEAT
RISER SYSTEM
Under certain weather conditions, it is possible for
ice to form in the venturi area of the carburetor. This
condition can be very dangerous because it can prevent the governor system from functioning properly,
which results in a “runaway” engine.
The most common weather conditions leading to this
problem are temperatures in the range of 25° F to
35° F (-4° C to 1.7° C), along with high humidity. This
ice formation also can be attributed to the load being
applied during these weather conditions. Generators
running with no-load or light loads applied usually
have the most problems.
The Summer/Winter Lever (Figure 2.3) should be
in the WINTER position for ambient temperatures
below 40° F (4.4° C) and in the SUMMER position for
ambient temperatures above 40° F (4.4° C).
Figure 2.3 – Heat Riser System
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 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.
When the heat riser is in the SUMMER (down) position (Figure 2.2), air is drawn into the air cleaner
from the upper intake tube.
When the heat riser is in the WINTER (up) position,
air is drawn from the lower intake tube, which is
positioned to draw the heated air near the exhaust
manifold.
To prevent carburetor icing, the owner/operator
should physically position the heat riser to the proper position dependent on the temperature.
9
Section 2 – Operation
Recreational Vehicle Generator
2.8.1 DO NOT OVERLOAD THE GENERATOR
Read the rated wattage/amperage capacity of the generator on the generator data decal (see "Generator
Identification").
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 time 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.
2.9 PROTECTION SYSTEMS
Figure 2.4 – Low Oil Pressure and
High Temperature Switches
2.9.3 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 2.5). During engine
cranking only, a positive DC (battery) voltage is delivered 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.
2.9. LOW OIL PRESSURE SWITCH
This switch (Figure 2.4) 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.
2.9.2 HIGH TEMPERATURE SWITCH
This switch (Figure 2.4), which has normally open
(N.O.) contacts, is mounted near the oil filter. The
contacts close if the temperature should exceed
approximately 293º F (145º C), initiating an engine
shutdown.
10
Figure 2.5 – Field Boost Circuit
2.9.4 OVERVOLTAGE PROTECTION
A solid-state voltage regulator (Figure 2.6) 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 electrical loads is controlled. When
the AC frequency is 60 Hertz, voltage is regulated at
120 volts (voltage-to-frequency ratio is 2-to-1).
Figure 2.6 – 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.
2.10 ADDITIONAL INFORMATION
2.10.1 ATTENTION REQUIRED
AFTER SUBMERSION
If the recreational vehicle generator has been submerged in water, it MUST NOT be started and operated. Following any submersion in water, have an
Authorized Service Dealer thoroughly clean and dry
the generator.
2.10.2 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.
Section 3 – Maintenance
Recreational Vehicle Generator
2.10.3 EFFECTS OF MOISTURE AND DIRT
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.
3.1 CHECKING THE ENGINE OIL LEVEL
For oil capacities and requirements, see section
“Engine Oil Requirements”. Check the engine crankcase oil level at least every eight hours of operation,
or before use. 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 Generator
3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
Change the engine oil after the first 25 hours of
•
operation. 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 fol-
•
lows (see Figure 3.1):
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF the engine.
2. Immediately after the engine shuts OFF, pull the
oil drain hose free of its retaining clip. Remove
the cap from the hose and drain the oil into a
suitable container. Loosening the oil fill cap will
allow the crankcase to drain faster.
3. After the oil has drained, replace the cap onto the
end of the oil drain hose. Retain the hose in the
clip.
4. With the oil drained, remove the old oil filter by
turning it counterclockwise.
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 wipe it dry with a clean,
lint-free cloth. This will be used later to check the
oil level.
8. Remove the oil fill cap on the rocker cover
and slowly add the proper type and amount
of recommended oil (see section "Engine Oil
Requirements"). Periodically use the dipstick to
check the oil level and continue to fill the crankcase until the oil reaches the dipstick “Full” mark.
DO NOT FILL ABOVE THE “FULL” MARK.
9. Install and tighten the oil fill cap and the dipstick
before operating the engine.
10. 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.
3.3 MAINTAINING 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 3.2):
1. Turn the two screws 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.
12
Figure 3.1 – Oil Maintenance Features
Section 3 – Maintenance

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.
8. Install the cover, foam precleaner and paper filter.
9. Tighten the two screws to retain the filter in
place.

3.3.2 CLEANING OR REPLACING
THE PAPER FILTER
Once each year or every 100 hours of operation
(whichever comes first), clean or replace the paper
filter. The new replacement filter must be flame
retardant. Service the paper filter more frequently if
operating the generator in extremely dusty or dirty
conditions. Use the following procedure (Figure 3.2):
1. Follow steps 1-3 in the "Cleaning the Foam
Precleaner" section; service the foam precleaner
if necessary.
2. Remove the paper filter.
3. Clean the air filter by tapping it gently on a solid
surface. If the filter is too dirty, replace it with a
new one. Dispose of the old filter properly.
4. Clean the air cleaner cover then reassemble
following steps 7-9 in the "Cleaning the Foam
Precleaner" section.
Figure 3.3 – Cleaning Air Intake
3.5 CHECKING THE ENGINE
SPARK PLUG
Clean the spark plug and reset the spark plug gap
every 100 hours of operation.
1. Clean the area around the base of the spark plug
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).
Sparking can occur if the wire terminal does not
fit firmly on the spark plug terminal end. If necessary, re-form the wire terminal to obtain a
tight fit.
Figure 3.4 – Setting the Spark Plug Gap
3.4 CLEAN AIR INTAKE
Clean all foreign material from the air intake (Figure
3.3) at least once every 100 hours of operation. Clean
more often if necessary.
Inspect the area around the generator exhaust muffler periodically and remove all grass, leaves, dirt,
etc., from this area.

Section 3 – Maintenance
Recreational Vehicle Generator
3.6 FUEL FILTER (GASOLINE ONLY)
Remove and replace the fuel filter (Figure 3.5) once
each year or every 100 hours of operation, whichever
comes first.
Figure 3.5 – Fuel Filter

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
covered, brush covered or grass covered unimproved
land, a spark arrestor may need to be installed. 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 the nearest
Authorized Service Dealer.
Exhaust mufflers supplied by the manufacturer are
spark arrestor types. The manufacturer's exhaust
mufflers for recreational 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.
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 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.
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.
3.9 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in
use. The generator battery should be inspected as
follows:
3.9.1 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 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.
14
Section 3 – Maintenance
Recreational Vehicle Generator
DANGER
Do not dispose of the battery in a fire. The bat-
tery 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.
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.
3.10 MAJOR SERVICE MANUAL
To obtain a service manual for the generator, contact the nearest Authorized Service Dealer or, go to
www.generac.com. Make sure to identify the MODEL
NUMBER and SERIES.
3.11 DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. The drive belt and
pulleys are warranted for the life of the generator. Drive
belt tension was properly adjusted before the unit was
shipped from the factory. If suspecting that the drive
belt tension is incorrect, contact an Authorized Service
Dealer.
3.12 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.
3.13 OUT OF SERVICE PROCEDURE
3.13.1 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
10W-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.
