TP-7070 7/1872 Section 3 Scheduled Maintenance
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
WARNING
The fuel system. Explosive fuel vapors can cause severe
injury or death. Vaporized fuels are highly explosive. Use
extreme care when handling and storing fuels. Store fuels in a
well-ventilated area away from spark-producing equipment
and out of the reach of children. Never add fuel to the tank
while the engine is running because spilled fuel may ignite on
contact with hot parts or from sparks. Do not smoke or permit
flames or sparks to occur near sources of spilled fuel or fuel
vapors. Keep the fuel lines and connections tight and in good
condition. Do not replace flexible fuel lines with rigid lines. Use
flexible sections to avoid fuel line breakage caused by
vibration. Do not operate the generator set in the presence of
fuel leaks, fuel accumulation, or sparks. Repair fuel systems
before resuming generator set operation.
Draining the fuel system. Explosive fuel vapors can
cause severe injury or death. Spilled fuel can cause an
explosion. Use a container to catch fuel when draining the fuel
system. Wipe up spilled fuel after draining the system.
Hot engine and exhaust system.
Can cause severe injury or death.
Do not work on the generator set until
it cools.
WARNING
Servicing the exhaust system. Hot parts can cause
severe injury or death. Do not touch hot engine parts. The
engine and exhaust system components become extremely
hot during operation.
Hot coolant and steam.
Can cause severe injury or death.
Before removing the pressure cap,
stop the generator set and allow it to
cool. Then loosen the pressure cap
to relieve pressure.
WARNING
Allow the engine to cool. Release pressure from the
cooling system before removing the pressure cap. To
release pressure, cover the pressure cap with a thick
cloth and then slowly turn the cap counterclockwise to
the first stop. Remove the cap after pressure has been
completely released and the engine has cooled. Check
the coolant level at the tank if the generator set has a
coolant recovery tank.
Hot surfaces.
CAUTION
Servicing the alternator. Hot parts can cause severe
injury or death. Avoid touching the alternator field or exciter
armature. When shorted, the alternator field and exciter
armature become hot enough to cause severe burns.
Risk of fire.
Can cause severe injury or death.
WARNING
Servicing the fuel system. A flash fire can cause severe
injury or death. Do not smoke or permit flames or sparks near
the fuel injection system, fuel line, fuel filter, fuel pump, or other
potential sources of spilled fuels or fuel vapors. Catch fuels in
an approved container when removing the fuel line or fuel
system.
Combustible materials. A fire can cause severe injury or
death. If using generator heaters during storage, remove
combustible materials such as covers from contact with the
heater or from areas where heat could potentially cause a fire.
