SAFETY PRECAUTIONS
The following symbols in this manual signal poten¬
tially dangerous conditions to the operator or equip¬
ment. Read this manual carefully. Know when these
conditions can exist. Then, take necessary steps to
protect personnel as well as equipment.
WARNING
I
Onan uses this symbol
throughout this manual to
warn of possible serious personal injury.
This symbol refers to possible
equipment damage.
Fuels, electrical equipment, batteries, exhaust gases
and moving parts present potential hazards that could
result in serious, personal injury Take care in follow¬
ing these recommended procedures.
• Use Extreme Caution Near Gasoline. A constant
potential explosive or fire hazard exists.
Do not fill fuel tank near unit with engine running.
Do not smoke or use open flame near the unit or
the fuel tank.
Be sure all fuel supplies have a positive shutoff
valve.
Fuel lines must be of steel piping, adequately
secured and free of leaks. Use a flexible section of
fuel line between generator set and stationary fuel
line in the vehicle. This flexible section must be
100% NON-METALLIC to prevent electrical
currents from using it as a conductor.
Have a fire extinguisher nearby. Be sure ex¬
tinguisher is properly maintained and be familiar
with its proper use. Extinguishers rated ABC by
the NFPA are appropriate for all applications.
Consult the local fire department for the correct
type of extinguisher for various applications.
• Guard Against Electric Shock
Remove electric power before removing protec¬
tive shields or touching electrical equipment. Use
rubber insulative mats placed on dry wood plat¬
forms over floors that are metal or concrete when
around electrical equipment. Do not wear damp
clothing (particularly wet shoes) or allow skin
surfaces to be damp when handling electrical
equipment.
Jewelry is a good conductor of electricity and
should be removed when working on electrical
equipment.
Always use an appropriately sized, approved
double-throw transfer switch with any standby
generator set. DO NOT PLUG PORTABLE OR
STANDBY SETS DIRECTLY INTO A HOUSE
RECEPTACLE TO PROVIDE EMERGENCY
POWER. It is possible for current to flow from
generator into the utility line. This creates ex¬
treme hazards to anyone working on lines to
restore power.
Use extreme caution when working on electrical
components. High voltages cause injury or death.
Follow all state and local electrical codes. Have all
electrical installations performed by a qualified
licensed electrician.
• Do Not Smoke While Servicing Batteries
Lead acid batteries emit a highly explosive
hydrogen gas that can be ignited by electrical
arcing or by smoking.
• Exhaust Gases Are Toxic
Provide an adequate exhaust system to properly
expel discharged gases. Check exhaust system
regularly for leaks. Ensure that exhaust manifolds
are secure and not warped.
Be sure the unit is well ventilated.
• Keep The Unit And Surrounding Area Clean
Remove all oil deposits. Remove all unnecessary
grease and oil from the unit. Accumulated grease
and oil can cause overheating and subsequent
engine damage and may present a potential fire
hazard.
Do NOT store anything in the generator com¬
partment such as oil or gas cans, oily rags,
chains, wooden blocks, propane tanks, etc. A
fire could result or the generator set operation
(cooling, noise and vibration) may be adversely
affected. Keep the compartment floor clean and
dry.
• Protect Against Moving Parts
Avoid moving parts of the unit. Loose jackets,
shirts or sleeves should not be permitted because
of the danger of becoming caught in moving
parts.
Make sure all nuts and bolts are secure. Keep
power shields and guards in position.
If adjustments must be made while the unit is
running, use extreme caution around hot
manifolds, moving parts, etc.
Do not work on this equipment when mentally or
physically fatigued.
