GENERAL SAFETY RULES
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.
Study these SAFETY RULES carefully before operating
or servicing applicable equipment. Become familiar
with this Owner’s Manual and with your generator.
Safe, efficient and reliable operation can only be
achieved if generator is properly installed, operated and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
The manufacturer suggests that these GENERAL
SAFETY RULES be copied and posted in potential
hazard areas of the recreational vehicle. Stress safety
to all operators and potential operators of this equip
ment.
The manufacturer cannot possibly anticipate every pos
sible circumstance that might involve a hazard. The
warnings in this manual, therefore, are not all-inclusive.
If you use a procedure, work method or operating tech
nique that Generac does not specifically recommend,
you must satisfy yourself that it is safe for you and
others. You must also make sure the procedure, work
method or operating technique that you chose, does not
render the generator to be unsafe.
• For fire safety, the recreational vehicle generator
must be properly installed and maintained. Instal
lation must comply with applicable codes and stan
dards. Also, the generator must be installed to
conform to the manufacturer’s detailed installation
instructions. After installation, do nothing that might
render the generator in noncompliance with such
codes, standards and instructions.
• The recreational vehicle generator produces ex
tremely dangerous electrical voltages and can
cause dangerous, and possibly fatal, electrical
shock. Avoid contact with bare wires, terminals,
etc., while the unit is running. If you must work
around an operating generator, stand on an insu
lated, dry surface to reduce shock hazard.
• Never work on this equipment or handle any elec
trical device while standing in water, while barefoot,
or while hands or feet are wet. Dangerous electrical
shock will result.
• Have the generator properly grounded (bonded)
during installation onto the vehicle, either by solid
mounting to the vehicle frame or chassis or by
means of an approved bonding conductor, if so
equipped. DO NOT reconnect the bonding conduc
tor to any generator part that might be removed or
disassembled during routine maintenance. If the
grounding conductor must be replaced, use only a
flexible conductor that is of No. 8 AWG copper wire
minimum.
Inspect fuel system frequently for leaks or damage.
Repair or replace any damaged or leaking compo
nent immediately. Never attempt to change, alter
or modify the generator fuel system in any way that
might affect safety or compliance with applicable
codes and standards.
In case of accident caused by electric shock, shut
down the source of electrical power at once. If you
cannot do this, free the victim from live conductor.
AVOID DIRECT CONTACT WITH THE VICTIM.
Use a dry board, dry rope, or other non-conducting
tool to free the victim from live conductor. If victim
is unconscious, apply CPR (cardio-puimonary re
suscitation) and get medical help.
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentra
tions, can cause unconsciousness or even death.
This exhaust system must have been properly in
stalled, complying strictly with applicable codes and
standards. After installing the unit, do nothing that
might render the unit unsafe or in non-compliance
with such codes and standards. The generator
compartment must be completely vapor-seaied
from 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.
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, leaking fuel, leaking oil or
leaking coolant.
The generator compartment needs adequate venti
lation to expel toxic fumes and diesel fuel vapors.
Do not alter the installation in any way that might
obstruct air and ventilation openings. Keep such
openings clear and unobstructed.
Keep hands, feet, clothing away from drive belts,
fans and other moving parts of this equipment.
Never remove a drive belt or fan guards while the
unit is operating.
Although diesel fuel is not as volatile as gasoline or
LP gas (liquid propane), it is still dangerous. Com
ply strictly with all laws and regulations regarding
the handling of diesel fuel.
Inspect the generator periodically. Repair or re
place all damaged or defective parts immediately.
Before performing any maintenance on the gener
ator set, disconnect its battery cables to prevent
accidental starting. First disconnect the cable from
the battery post indicated by a NEGATIVE, NEG or
(-)• Reconnect that cable last.

Preheat Switch: The diesel engine is equipped with
glow plugs, one for each cylinder. When you press the
preheat switch (Figure 3), the glow plugs heat the
engine combustion chamber for quicker starts in cold
weather. To preheat the combustion chamber for
quicker starts in cold weather. Press the switch and
between 15 and 30 seconds. Continue holding in the
preheat switch while cranking the engine until it starts.
NOTE: Refer to THE GENERATOR A-C CONNEC
TION SYSTEM on Page 4. Individual installations will
differ. If an overload occurs, the dual breakers will open
the hot stator leads (11 and 44). When the generator
has been connected for 120 volts only, one of the dual
circuit breakers will open stator AC output lead No. 11
(hot lead).
REMOTE START/STOP PANEL
A remote mounted Start/Stop Panel is available, which
allows you to start and stop the generator engine con
veniently from inside the vehicle.
You can also order a remote panel that includes meters
and gauges for monitoring low oil pressure, high coolant
temperature and low coolant level (Figure 5), in addition
to a start/stop switch. The panel also includes an am
meter, a voltmeter and an hourmeter.
Figure 3 — Generator Control Panel
Dual AC Circuit Breaker: Rated at 35 AC amps, the
circuit breaker (Figure 4) protects the generator’s AC
output circuit against overload and provides a method

BEFORE STARTUP
• Check Engine Crankcase Oil Level: Refer to
SPECIFICATIONS and MAINTENANCE sections
for procedures and recommendations.
CAUTION! Any attempt to crank or start the engine
before properly servicing it with recommended oil
will result in an engine failure.
NOTE: Engine was factory serviced with a high quality
oil classified "For Service CD" or "For Service CC" and
having a viscosity rating of SAE 30. The installer may
have refilled the crankcase with an oil more suitable for
ambient temperature ranges in your area.
® Check Coolant Level: Check coolant level prior to
initial use and at recommended intervals. Refer to
SPECIFICATIONS and MAINTENANCE sections
for procedures and recommendations.
® Check Fuel Supply: Make sure an adequate sup
ply of clean fuel is available to the engine. Many
installations include a Fuel Shutoff Valve, which you
must open before starting the engine.
NOTE: On some installations, the generator may have
been provided with its own fuel tank. On other installa
tions, the generator may "share" with the vehicle’s fuel
tank. When the vehicle’s tank is shared, some installers
may have installed a generator fuel pick up tube in the
shared tank that is shorter than the vehicle’s pick up
tube. When a shorter generator fuel pickup tube is
installed in the tank, the generator will run out of gas
while sufficient fuel remains in the tank for vehicle
engine operation.
START THE GENERATOR
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 whatever means
provided.
NOTE: If starting from the generator panel, turn OFF
loads by setting the generator’s main circuit breaker to
OFF or OPEN. If starting from a Remote Panel, turn
OFF loads using whatever means is provided in the
vehicle (such as a main circuit breaker.)
2. Press the preheat switch (if engine is cold) for
. between 15 and 30 seconds.
3. At the same time, hold the Engine-Start/Stop
Switch at START and press the preheat switch to
crank engine. Release the switch when the engine
starts.
4. Let the engine stabilize and warm up.
5. Turn ON electrical loads, using whatever means
provided.
SHUTTING DOWN THE GENERATOR
1. Turn OFF electrical loads, using whatever means
provided.
2. Let the engine run at no-load for a few minutes to
stabiize internal temperatures.
3. Set the Engine-Run/Stop Switch to STOP position.

AUTOMATIC LOW OIL PRESSURE
SHUTDOWN
The engine is equipped with a normally-closed (N.C.)
oil pressure switch (Figure 6). Engine oil pressure holds
the switch open during cranking and operation. Should
oil pressure drop below about 15 psi, the switch contacts
close and the engine automatically shuts down.
HIGH COOLANT TEMPERATURE
SHUTDOWN
This switch (Figure 7) is a normally open (N.O.) thermo
static device which is immersed in engine coolant.
Should engine coolant temperature exceed about
230°F (110°C), the switch contacts close and the en
gine shuts down.
ADDITIONAL INFORMATION
Figure 8 — Engine Controller Circuit Board
NOTE: After an overspeed shutdown, the engine may
be cranked and re-started. However, if the engine
overspeeds again, the engine shuts down again.
ENGINE GOVERNED SPEED
The generator is equipped with a 4-pole revolving field
(rotor) which must be driven at 1500 rpm to produce the
unit’s rated a-c frequency of 50 Hz. The diesel engine
governor was factory set to about 52 Hz. (1560) at
no-load. After installing it, the installation technician
should check and adjust the governed speed. Setting
the no-load frequency slightly high helps prevent exces
sive frequency, rpm and voltage droop under heavy
electrical loading.
DANGER; DO NOT TAMPER WITH THE ENGINE
GOVERNOR SETTINGS. EXCESSIVELY HIGH
ENGINE SPEEDS ARE DANGEROUS AND IN
CREASE THE RISK OF PERSONAL INJURY AND
DAMAGE TO EQUIPMENT AND/OR PROPERTY.
EXCESSIVELY LOW SPEEDS IMPOSE A HEAVY
LOAD ON THE ENGINE WHEN ADEQUATE EN
GINE POWER IS NOT AVAILABLE AND MAY
SHORTEN ENGINE LIFE. THE GENERATOR SUP
PLIES CORRECT RATED FREQUENCY AND
VOLTAGE ONLY AT THE PROPER SPEED.
SOME ELECTRICAL DEVICES MAY BE DAM
AGED BY INCORRECT FREQUENCY AND/OR
VOLTAGE. IF ENGINE SPEED APPEARS TO BE
INCORRECT, CONTACT YOUR NEAREST AU
THORIZED SERVICE FACILITY.
Figure 7 — High Coolant Temperature Switch
OVERSPEED SHUTDOWN
The generator control panel houses an Engine Control
ler circuit board (Figure 8). That circuit board receives
a-c frequency signals from generator stator leads 11
and 22. Should a-c frequency exceed about 72 Hz
(2160 rpm), circuit board action initiates an automatic
shutdown after a few seconds.
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 reducing oil consumption and enhancing
engine performance. During the break-in period, ob
serve the following rules:
• For the first 25 hours, run the generator at varying
electrical loads, to help set the enaine piston rings
properly.
- 7
Following the initial 25-hour break-in period, avoid
light electrical loads for the next 75 hours of opera
tion. The unit should be loaded at 50% (or more) of
its capacity during those 75 hours. Repeated light
loads during break-in period may improperly seat
the piston rings, resulting in blowby and high oil
consumption.
Check oil level frequently during the break-in period.
Add oil if needed. It is natural for the generator
engine to consume much oil until the piston rings
have seated properly.
When the 25-hour break-in period is done, complete
the tasks recommended under 25-HOUR CHECK
UP PERIOD.
25-HOUR CHECK-UP PERIOD
After the first 25 hours of operation have been com
pleted, contact an Authorized Service Facility for the
following maintenance. The Owner/Operator is respon
sible for any changes.
Change engine crankcase oil and oil filter.
Check all fluid levels.
Check all cooling system hoses and fittings for
damage, deterioration, looseness, etc. Check all
hose clamps for tightness and security.
Check engine for proper operation.
Inspect the diesel engine fuel system for leaks,
tightness and security of fuei fittings and hoses.
Inspect drive belts for condition and proper tension.
Inspect the exhaust system for damage, deteriora
tion, leaks, proper operation.
Inspect the electrical system.
Inspect the installation for safety violations, compli
ance with codes and standards.
FREEZING TEMPERATURE OPERATION
The engine cooling system should have been properly
filled with a 50-50 mixture of ethylene glycol base anti
freeze and soft water. When adding coolant to the
radiator or to the coolant recovery bottle, add only the
recommended 50-50 mixture. Refer to SPECIFICA
TIONS section. If the recommended 50-50 mixture is
added to the system consistently, the unit adequately
protects against freezing temperatures.
ATTENTION REQUIRED AFTER
SUBMERSION
If the generator has been submerged in water, it must
NOT be started and operated. Following any submer
sion in water, have an authorized Generac Service
Facility thoroughly clean and dry the generator.
OPERATING PRECAUTIONS
Never operate the generator set while the vehicle is
parked over dry leaves, dry grass or any other combus
tible substance. The generator’s exhaust sytem be
comes extremely hot and can cause fire if it is too close
to combustible materials.
The generator’s exhaust system gives off DEADLY
carbon monoxide gas. This dangerous gas, if breathed
in sufficient concentrations can cause unconsciousness
and even death. Never operate the generator set with
the vehicle inside any garage or other enclosed area.
Never operate the generator with a leaking exhaust
system. Close windows in the vicinity of the generator
exhuast outlet and take any other steps that may be
necessary to prevent exhaust gases from entering
rooms or areas occupied by people or animals.
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 wii! have an ad
verse affect on the insulation resistance of those wind
ings.
When moisture is allowed to remain in contact with
windings, some of that moisture will be retained in voids
and cracks in the insulation. This causes a reduced
insuiation resistance and will eventually cause prob
lems. Dirt will make the problem worse, since dirt tends
to hold moisture in contact with the windings. Salt (as
from sea air) will also worsen the problem since it tends
to absorb moisture from the air. Salt and moistsure,
when combined, form a good electrical conductor.

SPECIFICATIONS
FUEL REQUIREMENTS
Recommended fuel is any high quality, automotive type
diesel fuel conforming to JIS No. 2D diesel fuel. Keep
the fuel clean.
RECOMMENDED FLUIDS
Engine Oil; Use a high quality detergent oil classified
"For Service CC or CD." Detergent oils keep the engine
cleaner and reduce carbon deposits. Use oil having the
following SAE viscosity rating, based on the ambient
temperature range anticipated before the next oil
change:
Temperature Oil Grade (recommended)
Above 100°F
40°-l00°F
Below 40°F
Coolant: Use a mixture of half low silicate, ethylene
glycol base anti-freeze and half soft water. Coolant
system capacities may vary, depending on the specific
installation, length of system hoses, radiator use, etc.
Use only soft water and low silicate anti-freeze. If
desired, a high quality rust inhibitor may be added to the
recommended coolant mixture. When adding coolant,
always add the recommended 50-50 mixture.
CAUTION! Do not use any chromate base rust in
hibitor with ethylene glycol base anti-freeze or chro
mium hydroxide ("green slime") forms and causes
overheating. You must chemically clean engines
the have operated with a chromate base inhibitor
before adding ethylene glycol base anti-freeze.
Using any high silicate anti-freeze boosters or addi
tives will also cause overheating. In addition, using
any soluable oil inhibitor is not recommended for
this equipment.

OVERLOAD PROTECTION FOR ENGINE
D-C ELECTRICAL SYSTEM
Engine cranking, start up and running are controlled by
a solid state Engine Controller circuit board. Battery
voltage is delivered to that circuit board via 10 amp
circuit breaker and 14 amp in-line fuse. These overcurr
ent protection devices will open if circuit is overloaded.
CAUTION! If a circuit breaker opens or a fuse ele
ment melts, you should find the cause of the over
load before resetting the circuit breaker or replacing
the fuse.
10 amp Circuit Breaker: If the circuit breaker opens
due to an overload, you cannot crank or start the engine.
The circuit breaker is a "push-to-reset“ type. For emer
gency shutdown, pull the circuit breaker open. Also see
"Generator Control Panel" on Page 5.
_
14 Amp Fuse: If the fuse element melts open, you
cannot crank or start the engine. If you must replace
the fuse, use only identical 14 amp fuse (Figure 9).
30 amp Fuse: The generator set battery is charged
during operation by a d-c alternator, driven by the en
gine. This 30 amp fuse protects the charging circuit
