top performance can be obtained only when equipment is operated and maintained properly.
The following symbols in this manual alert you to potential hazards to the operator, service person and equipment.
alerts you to an immediate hazard which will result in severe personal injury or death.
WARNING
alerts you to a hazard or unsafe practice which can result in severe personal injury or death.
CAUTION
alerts you to a hazard or unsafe practice which can result in personal injury or equipment damage.
When equipped with an integral or add−on Auto− matic Generator Starting System (AGS) control,exhaust carbon monoxide (CO), electric shock, andmoving parts hazards are possible due to unex− pected starting. Turn off AGS whenever performingmaintenance or service, when the vehicle is storedbetween uses, is awaiting service, or is parked in agarage or other confined area.
Electricity, fuel, exhaust, moving parts and batteries present hazards which can result in severe personal injury or death.
GENERAL PRECAUTIONS
• Keep children away from the genset.
• Do not use evaporative starting fluids. They are highly explosive.
• To prevent accidental or remote starting while working on the genset, disconnect the negative (−) battery cable at the battery.
S Let the engine cool down before removing the coolant pressure cap or opening the coolant drain. Hot coolant under pressure can spray out and cause severe burns.
• Keep the genset and its compartment clean.
Excess oil and oily rags can catch fire. Dirt and gear stowed in the compartment can restrict cooling air.
• Make sure all fasteners are secure and torqued properly.
• Do not work on the genset when mentally or physically fatigued or after consuming alcohol or drugs.
• You must be trained and experienced to make adjustments while the genset is running—hot, moving or electrically live parts can cause severe personal injury or death.
• Used engine oil has been identified by some state and federal agencies as causing cancer or reproductive toxicity. Do not ingest, inhale, or contact used oil or its vapors.
• Benzene and lead in some gasolines have been identified by some state and federal agencies as causing cancer or reproductive toxicity. Do not to ingest, inhale or contact gasoline or its vapors.
• Keep multi-class ABC fire extinguishers handy.
Class A fires involve ordinary combustible materials such as wood and cloth; Class B fires, combustible and flammable liquid fuels and gaseous fuels; Class C fires, live electrical equipment. (ref. NFPA No. 10)
• Genset installation and operation must comply with all applicable local, state and federal codes and regulations.
GENERATOR VOLTAGE IS DEADLY!
S Disable the automatic genset starting feature(AGS) of an inverter−charger or other automat−ic starting device before servicing the genset toavoid unexpected starting.
• Generator electrical output connections must be made by a trained and experienced electrician in accordance with applicable codes.
• The genset must not be connected to shore power or to any other source of electrical power. Back-feed to shore power can cause electric shock resulting in severe personal injury or death and damage to equipment. An approved switching device must be used to prevent interconnections.

• Use caution when working on live electrical equipment. Remove jewelry, make sure clothing and shoes are dry, stand on a dry wooden platform or rubber insulating mat and use tools with insulated handles.
ENGINE EXHAUST IS DEADLY!
• Learn the symptoms of carbon monoxide poisoning in this manual and never sleep in the vehicle while the genset is running unless the vehicle is equipped with a working carbon monoxide detector.
• The exhaust system must be installed in accordance with the genset Installation Manual.
Engine cooling air must not be used for heating the working or living space or compartment.
• Inspect for exhaust leaks at every startup and after every eight hours of running.
• Make sure there is ample fresh air when operating the genset in a confined area.
FUEL IS FLAMMABLE AND EXPLOSIVE
• Do not smoke or turn electrical switches ON or
OFF where fuel fumes are present or in areas sharing ventilation with fuel tanks or equipment. Keep flame, sparks, pilot lights, arc-producing equipment and switches and all other sources of ignition well away.
• Fuel lines must be secured, free of leaks and separated or shielded from electrical wiring.
•
Leaks can lead to explosive accumulations of gas. Natural gas rises when released and can accumulate under hoods and inside housings and buildings. LPG sinks when released and can accumulate inside housings and basements and other below-grade spaces. Prevent leaks and the accumulation of gas.
BATTERY GAS IS EXPLOSIVE
• Wear safety glasses.
• Do not smoke.
• To reduce arcing when disconnecting or reconnecting battery cables, always disconnect the negative (−) battery cable first and reconnect it last.

FUEL RECOMMENDATIONS
WARNING
Gasoline and LPG are highly flammable and explosive and can cause severe per-
sonal injury or death. Do not smoke or turn elec-
trical switches ON or OFF where fuel fumes, tanks or equipment are present or in areas sharing ventilation. Keep flames, sparks, pilot lights, arc-producing equipment and switches and all other sources of ignition well away. Keep a type ABC fire extinguisher in the vehicle.
Gasoline Models
Use clean, fresh unleaded gasoline having a minimum octane rating (Anti-Knock Index) of 87.
CAUTION
Do not use gasoline or gasoline additives containing methanol because methanol can be corrosive to fuel system components.
Avoid using leaded gasoline because of the extra engine maintenance that will be required.
LPG Models
Use clean, fresh HD-5 grade liquified petroleum gas
(LPG) or equivalent product consisting of at least 90 percent propane. Commercial liquified petroleum gas fuels may contain more than 2.5 percent butane which can result in poor fuel vaporization and poor engine starting in low ambient temperatures (below
32° F (0° C).
Satisfactory performance on low-pressure LPG models requires that the LPG vapor be supplied at a pressure within the range indicated in Specifica-
tions.
WARNING
High LPG supply pressure can cause gas leaks which can lead to fire and severe personal injury or death. LPG supply pressure must be adjusted to Specifications by trained and experienced personnel.
ENGINE OIL RECOMMENDATIONS
Use API (American Petroleum Institute) performance Class SJ, SH or SG engine oil, which may be in combination with performance Class CH-4, CG-4 or CF-4 (for example: SJ/CH-4). Also look for the
SAE (Society of Automotive Engineers) viscosity
grade. Referring to Table 1, choose the viscosity
grade appropriate for the ambient temperatures expected until the next scheduled oil change.
Single-grade SAE 30 oil is preferable when temperatures are consistently above freezing. Multigrade oils are better when wide temperature variations are expected.

WARNING
EXHAUST GAS IS DEADLY!
Exhaust gases contain carbon monoxide, an odorless, colorless gas. Carbon monoxide is poisonous and can cause unconsciousness and death. Symptoms of carbon monoxide poisoning include:
•
Dizziness
•
Muscular Twitching
• Throbbing in Temples
• Headache
•
Weakness and Sleepiness • Inability to Think Clearly
•
•
Nausea
Vomiting
IF YOU OR ANYONE ELSE EXPERIENCES ANY OF THESE SYMPTOMS, GET OUT INTO THE FRESH
AIR IMMEDIATELY. If symptoms persist, seek medical attention. Shut down the genset and do not operate it until it has been inspected and repaired.
Never sleep in the vehicle with the genset running unless the vehicle is equipped with a working carbon monoxide detector. Primary protection against inhaling carbon monoxide, however, is proper installation of the exhaust system, daily (every eight hour) inspection for visible and audible exhaust system leaks.
CONDUCTING THE PRE-START CHECKS
Before the first start of the day and after every eight hours of operation, inspect the genset as instructed under CONDUCTING GENERAL INSPECTIONS
(Page 16). Keep a log of maintenance and the hours run and perform any maintenance that may be due.
See Returning the Genset to Service (Page 14) if the vehicle has been in storage.
Before each start:
1. Make sure all vehicle CO detectors are working.
2. Check for signs of fuel and exhaust leaks and for damage to the exhaust system.
3. To prevent overheating and to reduce fouling with dust and debris, make sure the genset’s normal ground clearance is not being reduced by sloping ground, curbs, logs or other objects.
Repark the vehicle if necessary and/or remove any objects blocking the air inlet or air outlet.
4. Turn off the air conditioner and other large appliances.
STARTING THE GENSET
Start the genset from the genset control panel or re-
mote control panel inside the vehicle (Page 7).
1. Push and hold the switch at START until the genset starts. (The remote START switch inside the vehicle should have a lamp which lights to indicate that the genset has started and is running.)
CAUTION
Cranking for longer than 10 seconds at a time can overheat and damage the starter. Do not crank for more than 10 seconds at a time and wait at least 30 seconds before trying again.
2. For top performance and engine life, especially in colder weather, let the engine warm up for two minutes before connecting appliances.
3. Check for fuel and exhaust leaks. Stop the genset immediately if there is a fuel or exhaust leak and have it repaired.
4. See Troubleshooting (Page 21) if the engine
does not crank or start after several tries.
5. Always secure the genset compartment door after starting the genset at the genset control panel.
WARNING
Proper engine cooling requires that the access cover be secured during operation. Also, hot engine parts can cause severe burns. Always secure the access cover as soon as the engine starts up.
8
STOPPING THE GENSET
Turn off the air conditioner and other large appliances and let the genset run for two minutes to cool down. This reduces backfiring and run-on.
Then press the switch to STOP to stop the genset.
RESTARTING THE GENSET
If the genset shuts down, disconnect or turn off as many appliances as possible and try restarting the genset. Reconnect only as many appliances as will not overload the genset or cause the circuit breaker to trip.
LOADING THE GENSET
The genset can power AC motors, air conditioners,
AC/DC converters and other appliances. How much appliance load* can be serviced depends upon the genset power rating. The genset will shut down or its circuit breakers will trip if the sum of the loads exceeds genset power.
To avoid overloading the genset and causing shutdowns, compare the sum of the loads of the appliances that are likely to be used at the same
time to the power rating of the genset. Use Table 2
or the ratings on the appliances themselves (if so marked) to obtain the individual appliance loads. It
may be necessary to run fewer appliances at the same time—the sum of the loads must not be greater than genset rating.
Note that the genset may shut down due to overload—even though the sum of the loads is less than genset rating—when a large motor or air conditioner is started last or cycles off and then on again. The reason for this is that motor startup load is much larger than running load. It may be necessary to
run fewer appliances when large motors and air conditioners are cycling on and off.

Note also that air density decreases as altitude increases, causing genset engine power to decrease.** Power decreases approximately 3.5
percent of rated power each 1000 feet (305 m) of in-
crease in elevation. See Table 3 for typical calcula-
tions. It may be necessary to run fewer
appliances at higher altitudes.

RESETTING CIRCUIT BREAKERS
If a circuit breaker in the main power distribution
panel of the vehicle or on the genset (Figure 7) trips,
either a circuit shorted or too many appliances were running. Note that the genset will continue to run after a circuit breaker trips.
If a circuit breaker trips, disconnect or turn off as many loads as possible and reset the circuit breaker. (Push the circuit breaker to OFF to reset it and then to ON to reconnect the circuit.) If the circuit breaker trips right away, either the electrical distribution system has a short or the circuit breaker is faulty. Call a qualified electrician.
If the circuit breaker does not trip, reconnect the appliances, one by one, up to a total load that does not overload the genset or cause the circuit breaker to trip. If a circuit breaker trips right away when an appliance is connected, the appliance probably has a short.
Electrical appliances and tools must be used and maintained properly and be properly grounded to cause the line circuit breakers to trip when short circuits occur.
WARNING
Short circuits in electrical appliances and tools can cause fire and electrical shock leading to severe personal injury or death. Read and follow the equipment and tool manufacturer’s instructions and warnings regarding use, maintenance and proper grounding.
CONNECTING SHORE POWER
A vehicle with provisions for connecting utility power must have an approved device to keep the genset and utility from being interconnected. See the genset Installation Manual for more information.
WARNING
Backfeed to shore power can cause electric shock resulting in severe personal injury or death and damage to equipment. The vehicle must have an approved device to prevent the genset from being interconnected with shore power.

OPERATING IN DUSTY ENVIRONMENTS
Pay particular attention to the following items when operating the genset in dusty environments:
1. Do not let dirt and debris accumulate inside the genset compartment. Keep the genset clean.
2. Perform air cleaner maintenance more often
3. Change engine oil every 50 hours.
4. Keep containers of engine oil that have been opened tightly closed to keep out dust.
BREAKING IN A NEW ENGINE
Proper engine break-in on a new genset or on one with a rebuilt engine is essential for top engine performance and acceptable oil consumption. Run the genset at approximately 1/2 rated power for the first
2 hours and then at 3/4 rated power for 2 more
hours. See LOADING THE GENSET (Page 9).
Proper engine oil and oil level are especially critical during break-in because of the higher engine temperatures that can be expected. Change the oil if not appropriate for the ambient temperatures during
break-in (Page 6). Check oil level twice a day or
every 4 hours during the first 20 hours of operation and change the oil after the first 20 hours of operation.
EXERCISING THE GENSET
Exercise the genset at least 2 hours each month if use is infrequent. Run the genset at approximately
1/2 rated power. See LOADING THE GENSET
(Page 9). A single two hour exercise period is bet-
ter than several shorter periods.
Exercising a genset drives off moisture, re-lubricates the engine, replaces stale fuel in fuel lines and carburetor and removes oxides from electrical contacts and generator slip rings. The result is better starting, more reliable operation and longer engine life.
STORING THE GENSET
Proper storage is essential for preserving top genset performance and reliability when the genset cannot be exercised regularly and will be idle for more than 120 days.
Storing the Genset
1. Gasoline Models − Fill the fuel tank with fresh fuel and add a fuel preservative (OnaFresh
TM
), following the instructions on the container label. Unless a preservative (stabilizer) is added, the gasoline in the fuel system will deteriorate causing fuel system corrosion, gum formation and varnish-like deposits which can lead to hard starting and rough operation.
Then run the genset for about 10 minutes at approximately 1/2 rated power to fill the fuel lines with the fresh fuel and preservative.
WARNING
Gasoline preservatives (stabilizers) are toxic. Follow the instructions on the container label. Avoid skin contact.
Wash your hands with soap and water after dispensing the fluid.
2. Change the engine oil and attach a tag indicat-
ing its oil viscosity (Page 6).
3. Remove the air filter and restart the genset.
While the genset is running, spray an engine fogger (OnaGard
TM
) into the carburetor, following the instructions on the container label, and then stop the genset. The fogger leaves a protective coat of oil on the internal surfaces of the engine.
4. Disconnect the battery cables, negative (−) cable first, from the starting battery and store the battery according to the battery manufac-
turer’s recommendations (Page 20).
5. Plug the exhaust tail pipe to keep out dirt, moisture, rodents and such.
6. Close the fuel supply valve (if so equipped).
7. Turn OFF the AC circuit breaker (Page 10).

WARNING
Do not open the carburetor drain when the engine is hot. Close the drain immediately after draining. Failure to heed this warning can lead to fire resulting in severe personal injury or death.
8. Gasoline Models − Draining the carburetor float bowl prevents deposits of gum from clogging the tiny passages in the carburetor as the gasoline in the bowl evaporates during storage.
If the carburetor has a drain (Figure 9), drain it
as follows:
A. Let the engine cool down thoroughly.
B. Place paper towels under the drain to absorb all of the drainage (less than 1/2 cup).
C. Open the drain valve by turning counterclockwise with a screwdriver.
D. Immediately close the drain valve after draining by turning clockwise with a screwdriver until just snug.
9. LPG Models − Check local ordinances if the vehicle is to be garaged. Generally, ordinances require that the LPG system be leak-free, that the LPG container not be filled beyond specified limits, that the container shutoff valve be closed and that the vehicle not be parked near sources of heat or ignition.
WARNING
LPG leaks can lead to explosive accumulations in pits, sumps or other below-grade locations. Comply with all local ordinances regarding the garaging of vehicles with LPG engine fuel systems.

Returning The Genset To Service
1. Check the oil tag on the genset and change the oil if the viscosity indicated is not appropriate for
the temperatures expected (Page 6).
2. Reconnect the starting battery, negative (−) ca-
3. Remove the plug from the exhaust tailpipe.
4. Change the air filter element if it is dirty.
5. Open the fuel supply valve (if so equipped).
6. Inspect the genset (Page 16).
7. Start the genset. There may be smoke and rough operation for a few minutes until the oil from the fogger burns off. If the engine does not start, clean or replace the spark plug, which may have been fouled by the fogger.
8. Turn ON the AC circuit breaker (Page 10) when
the genset is ready to power appliances.
14
Periodic Maintenance
Periodic maintenance is essential for top perfor-
mance and long genset life. Use Table 4 as a guide
for normal periodic maintenance. In hot and dusty environments some maintenance procedures should be performed more frequently, as indicated by the footnotes in the table. Keeping a log of maintenance performed and hours run will help you keep genset maintenance regular and provide a basis for
supporting warranty claims (Page 26).
Maintenance, replacement or repair of emission control devices and systems may be performed by any engine repair establishment or individual. However, warranty work must be completed by an authorized Onan dealer.

CONDUCTING GENERAL INSPECTIONS
Inspect the genset before the first start of the day and after every eight hours of operation.
Oil Level
Check engine oil level (Page 17).
Exhaust System
Look and listen for exhaust system leaks while the genset is running. Shut down the genset if a leak is found and have it repaired before operating the genset again.
Look for openings or holes between the genset compartment and vehicle cab or living space if the genset engine sounds louder than usual. Have all such openings or holes closed off or sealed to prevent exhaust gases from entering the vehicle.
Replace dented, bent or severely rusted sections of the tailpipe and make sure the tailpipe extends at least 1 inch (25.4 mm) beyond the perimeter of the vehicle.
Park the vehicle so that the genset exhaust gases can disperse away from the vehicle. Barriers such as walls, snow banks, high grass, brush and other vehicles can cause exhaust gases to accumulate in and around the vehicle.
Do not operate power ventilators or exhaust fans while the vehicle is standing with the genset running. The ventilator or fan can draw exhaust gases into the vehicle.
Check all CO monitors to assure proper operation.
WARNING
EXHAUST GAS IS DEADLY! Do not operate the genset if there is an exhaust leak or any danger of exhaust gases entering or being drawn into the vehicle.
WARNING
Do not park the vehicle in high grass or brush. Contact with the exhaust system can cause a fire.
Fuel System
Check for leaks at the hose, tube and pipe fittings in the fuel supply system while the genset is running and while it is stopped. Do not use a flame to check
for LPG leaks. Check flexible fuel hose sections for cuts, cracks, and abrasions. Make sure the fuel line is not rubbing against other parts. Replace worn or damaged fuel line parts before leaks occur.
If you smell gas, close the LPG container shutoff valve and have the genset serviced before using it again.
WARNING
Gasoline and LPG are highly flammable fuels and can cause severe personal injury or death. Repair leaks right away.
Battery Connections
Check the battery terminals for clean, tight connections. Loose or corroded connections have high electrical resistance which makes starting harder. See MAINTAINING THE BATTERY AND
BATTERY CONNECTIONS (Page 20).
WARNING
Arcing at battery terminals or light switch or other equipment or flames and sparks can ignite battery gas causing severe personal injury—Ventilate battery area before working on or near battery—Wear safety glasses—Do not smoke—Switch trouble light ON / OFF away from battery—Do not disconnect battery cables while genset is running or vehicle battery charging system is on—Always disconnect negative (−) cable first and reconnect it last.
Mechanical
Look for mechanical damage and listen for unusual noises. Check the genset mounting bolts.
Check to see that the genset air inlet and outlet openings are not clogged with debris or blocked.
Clean accumulated dust and dirt from the genset.
Do not clean the genset while it is running or still hot.
Protect the generator, air cleaner, control panel, and electrical connections from water, soap and cleaning solvents.
WARNING
Always wear safety glasses when using compressed air, a pressure washer or a steam cleaner to avoid severe eye injury.
16
CHECKING ENGINE OIL LEVEL
Park the vehicle on level ground and stop the genset before checking engine oil level.
WARNING
Crankcase pressure can blow hot engine oil out the fill opening causing severe burns. Always stop the genset before removing the oil fill cap.
1. Unscrew the oil fill cap and wipe oil off the dip-
stick (Figure 10). Reinsert the dipstick, but do
not screw the cap down. Remove the dipstick
again and check the oil level on the dip stick.
2. Add or drain oil as necessary. See ENGINE OIL
RECOMMENDATIONS (Page 6). Keep the
oil level between the FULL and ADD marks.
CAUTION
Too much oil can cause high oil consumption. Too little oil can cause severe engine damage. Keep the oil level between the FULL and ADD marks.
3. Screw the oil fill cap back on securely.
CHANGING ENGINE OIL
WARNING
State and federal agencies have determined that contact with used engine oil can cause cancer or reproductive toxicity. Try to avoid skin contact and breathing of vapors. Use rubber gloves and wash exposed skin.
Refer to Table 4 for scheduled engine oil change.
Change oil more often in hot and dusty environments.
1. Run the engine until warm, stop it and remove
2. Place a pan under the oil drain plug and remove
the plug (Figure 11) with a 14 mm socket. Let
all oil drain from the engine and then secure
the drain plug. If you have a torque wrench, tighten the plug to 21 lbs-ft (27 N-m).
3. Refill with 1 quart (0.95 l) of oil. See ENGINE
OIL RECOMMENDATIONS (Page 6). Check
the oil level and add or drain oil as necessary.
4. Screw the oil fill cap on securely.
5. Dispose of the used oil in accordance with local environmental regulations.

REPLACING THE AIR FILTER ELEMENT
Refer to Table 4 for scheduled air filter replacement.
Under dusty operating conditions inspect and change the air filter element more often. To change
the air filter element (Figure 12), lift the filter cover
out of the scroll housing and pull the filter retainer straight out. Install the new filter with the open end of the filter facing the carburetor, as shown.
REPLACING THE SPARK PLUG
Refer to Table 4 for scheduled spark plug replace-
ment. (The genset has one spark plug, Figure 13).
The spark plug must be in good condition for proper engine starting and performance. A spark plug that fouls frequently or has heavy soot deposits indicates that the engine needs service. See Trouble-
Always thread the spark plug in by hand until it seats, to prevent crossthreading, and torque to
13 lbs-ft (17 N-m). If you don’t have a torque wrench, turn the spark plug an additional 1/4 turn, if being reused, or 3/8 to 1/2 turns if new.

FAULT CODE BLINKING
At fault shutdown, the status indicator light will repeatedly blink sets of 1, 2, 3 or 4 blinks.
S One blink indicates shutdown due to high engine coolant temperature.
S Two blinks indicate shutdown due to a loss of engine oil pressure.
S Three blinks indicate a service fault. Press
Stop once to cause the two-digit, second-level
shutdown code to blink. (Pressing Stop again will stop the blinking.) The two-digit code consists of 1, 2, 3, 4 or 5 blinks, a brief pause, and then 1 to 9 blinks. The first set of blinks represents the tens digit and the second set of blinks the units digit of the shutdown code number.
For example, shutdown code No. 36 appears as: blink-blink-blink—pause—blink-blink-blink-blink-blink-blink—
long pause—repeat
S Four blinks indicate that cranking time exceeded 35 seconds.
•
Fault Code Nos. 1, 2, 3, and 4 are first level faults.
Pay close attention to the pause sequence to avoid interpreting first level faults as second-level Fault
Codes Nos. 11, 22, 33, or 44.
•
To avoid the possibility of anyone misinterpreting
Code Nos. 3 and 4 as Code Nos. 33 and 44, the latter have not been assigned faults.
RESTORING FAULT CODE BLINKING
The fault code stops blinking after five minutes.
Press Stop three times within three seconds to restore fault code blinking.
Note: The last fault logged will blink even though the condition that caused the shutdown may have been corrected.
