Study these SAFETY RULES carefully before installing, operating
or servicing this equipment. Become familiar with this manual and
with the unit. The generator can operate safely, efficiently and reli-
ably only if it is properly installed, operated and 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, ensure that it is
safe for others. Also make sure the procedure, work method or
operating technique that chosen does not render the generator
unsafe.
DANGER
Despite the safe design of this generator,
operating this equipment imprudently, neglect-
ing 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) sleepi-
ness. 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 running unless the•
vehicle has a working carbon monoxide detector. The exhaust
system must be installed in accordance with the genset instal-
lation manual. Make sure there is ample fresh air when operat-
ing 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 ventilating 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 ven-
tilation 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 generator, discon-•
nect 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 dan-
gerous operating conditions from leaking exhaust gases, fuel
leakage, oil leakage, etc.
Safety Rules

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 bar-
riers 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 stand-•
ing in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
During installation onto the vehicle, have the generator prop-•
erly grounded (bonded) either by solid mounting to the vehicle
frame or chassis, or by means of an approved bonding conduc-
tor. 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 mainte-
nance. 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 pos-
sible, 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.
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 noth-
ing 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 elec-
trical 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.

1.2 GENERATOR APPLICABILITY
These generators have been designed and manufactured for sup-
plying 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 applica-
tion, write or call the factory. Do not use the unit until advised by
competent authority.
DANGER
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:
RV 45 G & LP: 120 and/or 240 volts, single phase, 60 Hz elec-•
trical loads. These loads can require up to 4500 watts (4.5 kW)
of total power, but cannot exceed 37.5 AC amperes of current
at 120 volts or exceed 18.7 AC amperes at 240 volts.
RV 55 G & LP: 120 and/or 240 volts, single phase, 60 Hz elec-•
trical 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.
RV 65 G & LP: 120 and/or 240 volts, single phase, 60 Hz elec-•
trical 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.
Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
nated to avoid overloading. Applying excessive-
ly high electrical loads may damage the genera-
tor and may shorten its life. Add up the rated
watts of all electrical lighting, appliance, tool
and motor loads the generator will power at one
time. This total should not be greater than the
wattage capacity of the generator. If an electri-
cal 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.
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 recommenda-
tions for installing the unit into an industrial vehicle. After installa-
tion, installers should forward the Installation Manual to Owners/
Operators for their information.
Owners/Operators have the responsibility to make sure that noth-
ing 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 manu-
facturer 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 — two 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 1.1 shows the generator lead wire
connections for 120VAC ONLY.
Figure 1.1 – Connection for 120 Volts Only

2. 120/240 VAC loads — one load with a maximum total watt-
age requirement equal to the generator’s rated power output,
and 240V across the generator output terminals; or two sepa-
rate 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 the "Line Breakers" section for circuit

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.
1.6.1.1 Fuel Consumption (gph)
Model 10% Load 50% Load 100% Load
RV45G .33 .45 .73
RV55G .35 .55 .89
RV65G .37 .65 .97
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 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.
The manufacturer does not recommend using
any gasoline containing alcohol (such as “gaso-
hol”). If using any gasoline containing alcohol, it
must not contain more than 10 percent ethanol
(Do not use E85), 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
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Use no special additives. Select the
oil's viscosity grade according to the expected operating tempera-
ture (also see chart).
SAE 30• ÎAbove 32° F
10W-30• ÎBetween 40° F and -10° F
Synthetic 5W-30• Î10° F and below
SAE 30
SAE 3 0

2.1.2 7.5 AMP 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 replaced, use
only an identical 7.5 amp replacement fuse.
2.1.3 LINE BREAKERS
Protects generator’s AC output circuit against overload, i.e., pre-
vents unit from exceeding wattage/amperage capacity. The circuit
breaker ratings are as follows:
Model Cir. Breaker 1 Cir. Breaker 2 240 Volt
RV45 20A 20A 20A 2P
RV55 20A 30A 25A 2P
RV65 30A 30A 30A 2P
NOTE:
If this generator has been reconnected for dual volt-
age AC output (120/240 volts), install line breakers
having an amperage rating equal to that stated in the
preceding chart. The replacement line breakers con-
sist of two separate breakers with a connecting piece
between the breaker handles (so that both breakers
will operate at the same time). If the unit is recon-
nected for dual voltage, it is no longer RVIA listed.
2.1.4 DIAGNOSTICS
If the generator shuts down due to a fault, the indicator will flash a
code to identify the problem.
2 Flashes = Low Battery (Voltage falls below 11.0 VDC for one•
minute)
NOTE:
Alarm will clear automatically if voltage rises over
11.0 VDC. Battery voltage is not monitored during
crank cycle.
3 Flashes = Overcrank (Unit does not start through entire start•
cycle)
4 Flashes = Overspeed (Alternator spins at 4200 rpm/72 Hz•
or greater)
5 Flashes = Low Oil Pressure (Drops below the 5 psi threshold•
of the switch)
NOTE:
There is a five second delay of the alarm when the
engine is first started up.
6 Flashes = High Oil Temperature (Unit shuts down when tem-•
perature switch limit is reached)
NOTE:
As the unit cools down it will attempt to restart auto-
matically when the temperature switch opens again.
7 Flashes = Underspeed (Alternator spins less than 3240•
rpm/54 Hz for three (3) seconds)
NOTE:
After a fault is indicated, press stop momentarily to
clear the alarm once the problem is fixed.
2.2 OPTIONAL REMOTE
START/STOP PANEL
A remote mounted Start/Stop Panel is available that allows start-
ing and stopping the generator engine conveniently from inside the

generator run lamp, and a wire harness.
2.3 AUTOMATIC CHOKE
This engine is equipped with an automatic choke that consists of
two main components: a choke solenoid and prechoke (Gasoline
only.).
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 (Gasoline only.).
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 (Gasoline only.).
2.4 BEFORE STARTING THE
ENGINE
NOTE:
Instructions and information in this manual assume
the generator has been properly installed, con-
nected, 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. (See Part II -
Installation Instructions.)

Section 2 – Operation
Recreational Vehicle Generators
2.4.2 ENGINE LUBRICATION
Have the engine crankcase properly serviced with the recommend-
ed oil before starting. Refer to sections "Engine Specifications",
"Checking the Engine Oil Level" and "Changing the Engine Oil and/
or Oil Filter" for oil servicing procedures and recommendations.
Any attempt to crank or start the engine before
it has been properly serviced it with the recom-
mended oil may result in an engine failure.
2.4.3 FUEL SUPPLY
The engine must have an adequate supply of proper fuel to oper-
ate. 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.
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 concen-
trations, 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 installa-
tion 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 vehi-
cle 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 provided 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 pro-
vided in the vehicle (such as a main circuit breaker).
Electrical load circuits should be turned ON after the
generator has started, stabilized and warmed up.
2. To crank and start the engine, push up on the Start/Stop
switch momentarily and release. There is a delay as the fuel
pump primes and the generator automatically begins the start
sequence (Note the flashing light on the switch.).
3. Let the engine run at no-load for a few minutes to stabilize and
warm up.
4. 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.

Section 2 – Operation
Recreational Vehicle Generators
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 appli-
ances.
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.
2.7.2 DO NOT OVERLOAD THE GENERATOR
Read the rated wattage/amperage capacity of the generator on the
generator data label (See the "Generator Identification" section.).
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 oper-
ated 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 2.2) has normally closed (N.C.) contacts that
are held open by engine oil pressure during cranking and operat-
ing. 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 2.2), 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 mod-
els.
Figure 2.2 – 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 compo-
nents are part of a “field boost” circuit (Figure 2.3). 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.
Figure 2.3 – Field Boost Circuit

11
Section 3 – Maintenance
Recreational Vehicle Generators
2.8.4 OVERVOLTAGE PROTECTION
A solid-state voltage regulator (Figure 2.4) 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 125 to 120 volts.
Figure 2.4 – Solid State Voltage Regulator
2.8.5 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 mate-
rials 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 the “Engine Oil
Requirements” section. 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 oper-
ating the engine.

3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
Oil Change Intervals – see Section “RV Generator Service
Interval”.
To change the oil and 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 round
access grommet from underneath the front of the generator.
Place a suitable container underneath to catch all the drain
oil.
3. Use the 0G4818 tool (supplied with the generator) to turn the
old filter counter-clockwise and remove. Let oil drain into the
container located directly below.
4. Locate the oil drain hose inside and pull the yellow drain plug
out of the access hole (Figure 3.1).
5. Turn the yellow cap counter-clockwise to remove and finish
draining the old oil.
6. After the oil has been drained, replace the oil drain plug by
tightening it clockwise and return.
7. Clean off the oil filter bracket and any old oil that may have
spilled while draining.
8. Apply a light coating of clean engine oil the gasket of the new
oil filter (Figure 3.2).
9. Screw the new oil filter on by hand until its gasket lightly con-
tacts the oil filter adapter. Then, tighten the filter an additional
¾ to one turn. Replace and secure the round access grom-
met.

Reset the spark plug gap or replace the spark plugs as necessary.
See the Service Schedule section for maintenance requirements.
1. Clean the area around the base of the spark plugs to keep dirt
and debris out of the engine.
2. Remove the spark plugs and check the condition. Replace the
spark plugs if worn or if reuse is questionable. See the Service
Schedule section for recommended interval. Clean by scrap-
ing or washing using a wire brush and commercial solvent.
Do not blast the spark plugs to clean.
3. Check the spark plug gap using a wire feeler gauge. Adjust the
gap to 0.76mm (0.030 inch) by carefully bending the ground
electrode if necessary (Figure 3.4).

3.5 FUEL FILTER (GASOLINE ONLY)
Remove and replace the fuel filter (Figure 3.5) every 400 hours of
operation.
Figure 3.5 – Fuel Filter
3.6 CLEAN SPARK ARRESTOR
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen every 200 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 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 screw.•

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 con-
taminate the generator fuel system.
3.8 BATTERY MAINTENANCE
NOTE:
This generator is not equipped with an internal bat-
tery charger. It is intended for use in systems where
an external battery charger is installed by the RV
O.E.M. or an aftermarket installer.
All lead-acid batteries will discharge when not in use. The generator
battery should be inspected as follows:
3.8.1 WEEKLY
Inspect the battery posts and cables for tightness and corro-•
sion. Tighten and clean as necessary.
Check the battery fluid level of unsealed batteries and, if nec-•
essary, 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 super-
vised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized person-
nel away from batteries.
Damage will result if the battery connections are
made in reverse.

DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batter-
ies give off explosive hydrogen gas. This gas
can form an explosive mixture around the bat-
tery for several hours after charging. The slight-
est spark can ignite the gas and cause an explo-
sion. 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 equip-
ment near the battery. Discharge static electric-
ity 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 pre-
cautions 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 bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.
3.9 ADJUSTING VALVE CLEARANCE
After the first 50 hours of operation, check the valve
clearance in the engine, adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please contact the Authorized
Dealer for service assistance. This is a very important step to
insure longest life for the engine.
To check valve clearance:
The engine should be cool before checking. If valve clearance is•
0.002" - 0.004" (0.05 - 0.1mm), adjustment is not needed.
Remove spark plug wires and position wires away from plugs.•
Remove spark plugs.•
Make sure the piston is at Top Dead Center (TDC) of its com-•
pression stroke (both valves closed). To get the piston at TDC,
remove the intake screen at the front of the engine to gain
access to the flywheel nut. Use a large socket and socket
wrench to rotate the nut and hence the engine in a clockwise
direction. While watching the piston through the spark plug
hole. The piston should move up and down. The piston is at
TDC when it is at its highest point of travel.
To adjust valve clearance (if necessary):
Make sure the engine is at 60° to 80° F.•
Make sure that the spark plug wire is removed from the spark•
plug and out of the way.
Remove the four screws attaching the valve cover with a #2 or•
#3 Phillips screwdriver.
Loosen the rocker jam nut. Use an 10mm allen wrench to turn•
the pivot ball stud while checking clearance between the rocker
arm and the valve stem with a feeler gauge. Correct clearance
is 0.002-0.004 inch (0.05-0.1 mm). (Figure 3.7).

When valve clearance is correct, hold the pivot ball stud in place
with the allen wrench and tighten the rocker arm jam nut. Tighten
the jam nut to 174 in/lbs. torque. After tightening the jam nut,
recheck valve clearance to make sure it did not change.
Install new valve cover gasket.•
Re-attach the valve cover.•
NOTE:
Start all four screws before tightening or it will not be
possible to get all the screws in place. Make sure the
valve cover gasket is in place.
Install spark plugs.•
Re-attach the spark plug wire to the spark plug.•
On the GT-530, repeat the process for the other cylinder.•
3.10 MAJOR SERVICE MANUAL

est Authorized Service Dealer. Make sure to identify the MODEL
NUMBER and SERIES. Manuals can be obtained from the internet
website or a service dealer.
3.11 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.
3.12 EXERCISING THE GENERATOR
The manufacturer recommends starting and operating the genera-
tor 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

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) sleepi-
ness. 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 running unless the•
vehicle has a working carbon monoxide detector. The exhaust
system must be installed in accordance with the genset instal-
lation manual. Make sure there is ample fresh air when operat-
ing 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 ventilating 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 ven-
tilation 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.
Before performing any maintenance on the generator, discon-•
nect 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.
DANGER: For fire safety, installation of a generator into a recreational vehicle must comply strictly with article 551, NFPA 70;
ANSI C1-1975; AND, ANSI A119.2-1975/NFPA 501C “Standard for Recreational Vehicles” (Part 3, “Installation of Electrical
Systems”). In addition, installation must comply with the manufacturer’s instructions and recommendations.

