Attach a "Do Not Operate" warning tag or a similar
warning tag to the start switch or to the controls
before the engine is serviced or before the engine is
repaired. Attach the warning tags to the engine and
to each operator control station. When appropriate,
disconnect the starting controls.
Do not allow unauthorized personnel on the engine,
or around the engine when the engine is being
serviced.
• Tampering with the engine installation or
tampering with the OEM supplied wiring can be
dangerous. Personal injury, death and/or engine
damage could result.
• Vent the engine exhaust to the outside when the
engine is operated in an enclosed area.
• If the engine is not running, do not release the
secondary brake or the parking brake systems
unless the vehicle is blocked or unless the vehicle
is restrained.
Unless other instructions are provided, perform
the maintenance under the following conditions:
• The key switch is in the OFF position.
• The engine is stopped. Ensure that the engine
cannot be started.
• The protective locks or the controls are in the
applied position.
• Engage the secondary brakes or parking brakes.
• Block the vehicle or restrain the vehicle before
maintenance or repairs are performed.
• After the ECM has powered down, disconnect the
i08314780
batteries when maintenance is performed or when
the electrical system is serviced. Disconnect the
battery ground leads. Use electrical insulating tape
on the leads to help prevent sparks.
• If equipped, disconnect the connectors for the unit
injectors that are located on the valve cover base.
This action will help prevent personal injury from
the high voltage to the unit injectors. Do not come
in contact with the unit injector terminals while the
engine is operating.
• Do not attempt any repairs or any adjustments to
the engine while the engine is operating.
• Do not attempt any repairs that are not
understood. Use the proper tools. Replace any
equipment that is damaged or repair the
equipment.
• For initial start-up of a new engine or for starting
g00104545
an engine that has been serviced, make
provisions to stop the engine if an overspeed
occurs. The stopping of the engine may be
accomplished by shutting off the fuel supply and/
or the air supply to the engine. Ensure that only
the fuel supply line is shut off. Ensure that the fuel
return line is open.
• Start the engine from the operators station (cab).
Never short across the starting motor terminals or
the batteries. This action 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.
To help prevent spraying or splashing of pressurized
fluids, hold a rag over the part that is being removed.
Remove the following parts with caution.
• Filler caps
• Grease fittings
• Pressure taps
• Breathers
• Drain plugs
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 plate or the device. Before removing the last
two bolts or nuts, pry the cover loose to relieve any
spring pressure or other pressure.
