MOVING PARTS CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH
•
Disable AUTO, stop the APU and disconnect
the battery cables (negative [ − ] first) from the
batteries before servicing the APU.
• Do not wear loose clothing or jewelry near
moving parts such as fans, belts and pulleys.
• Keep hands away from moving parts.
•
Keep guards in place over fans, belts, pul-
leys, and other moving parts.
BATTERY GAS IS EXPLOSIVE
• Do not smoke near batteries.
• Wear safety glasses when servicing batter-
ies.
•
Disable AUTO, stop the APU and disconnect
the battery cables from the batteries before
servicing the batteries.
• Always disconnect negative ( − ) first and re-
connect last to prevent sparks between tools
and vehicle frame.
• Secure battery terminal protective covers to
prevent accidental shorting with metal tools.
DIESEL FUEL IS COMBUSTIBLE
• 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 flames, sparks, pilot lights,
arc-producing equipment and all other
sources of ignition well away.
• Fuel lines must be secured, free of leaks and
separated or shielded from electrical wiring.
FLAMMABLE VAPORS CAN BE IGNITED
BY VEHICLE ELECTRICAL SYSTEMS
AND CAN CAUSE A DIESEL ENGINE TO
OVERSPEED
• Disable AUTO and stop the APU before fuel-
ing the vehicle.
• Do not operate the diesel-powered APU
where there are or can be flammable vapors
created by fuel spills, gas leaks, etc. Flam-
mable vapors drawn into a diesel engine air
intake system can cause the engine to over-
speed, which can result in fire, explosion and
equipment damage. The owners and opera-
tors of the APU are solely responsible for safe
operation.
GENERAL PRECAUTIONS
• Keep children away from the APU.
• Do not use evaporative starting fluids. They
are highly explosive.
• Let the engine cool down before removing
the coolant pressure cap or opening the cool-
ant drain. Hot coolant under pressure can
spray out and cause severe burns.
• Keep the APU and its compartment clean.
Excess oil and oily rags can catch fire. Dirt
and gear stowed in the compartment can re-
strict cooling air.
• Make sure all fasteners are secure and
torqued properly.
• Do not perform APU maintenance or service
when mentally or physically fatigued or after
having consumed alcohol or drugs.
• You must be trained and experienced to
make adjustments while the APU is run-
ning—hot, moving or electrically live parts
can cause severe personal injury or death.
• Used engine oil has been identified by some
U. S. state and federal agencies as causing
cancer or reproductive toxicity. Do not ingest,
inhale, or contact used oil or its vapors.
• Ethylene glycol, used as engine antifreeze, is
toxic to humans and animals. Clean up spills
and dispose of used engine coolant in accor-
dance with local environmental regulations.
• Keep a multi-class ABC fire extinguisher in
the vehicle. Class A fires involve ordinary
combustible materials such as wood and
cloth. Class B fires involve combustible and
flammable liquids and gaseous fuels.
Class C fires involve live electrical equip-
ment. (ref. NFPA No. 10)
• APU installation and operation must comply
with all applicable local, state and federal
codes and regulations.
