• Disconnect the batteries when maintenance is
performed or when the electrical system is
serviced. Disconnect the battery ground leads.
Tape the leads in order to help prevent sparks.

unit injectors. Do not come in contact with the unit
injector terminals while the engine is operating.

stop the engine if an overspeed occurs. This may
be accomplished by shutting off the fuel supply
and/or the air supply to the engine.

Never short across the starting motor terminals or
the batteries. This could bypass the engine neutral
start system and/or the electrical system could be
damaged.
Engine exhaust contains products of combustion
which may be harmful to your health. Always start the
engine and operate the engine in a well ventilated
area. If the engine is in an enclosed area, vent the
engine exhaust to the outside.
Cautiously remove the following parts. To help
prevent spraying or splashing of pressurized fluids,
hold a rag over the part that is being removed.
• Filler caps

Use caution when cover plates are removed.
Gradually loosen, but do not remove the last two bolts
or nuts that are located at opposite ends of the cover
