Engine Starting
Before Starting Engine
Perform the required daily maintenance and other
periodic maintenance before the engine is started.
Inspect the engine compartment. This inspection can
help prevent major repairs at a later date. Refer to
the Operation and Maintenance Manual,
"Maintenance Interval Schedule" for more
information.
• Ensure that the engine has an adequate fuel
supply.
• Open the fuel supply valve (if equipped).
• Ensure that the engine has an adequate diesel
exhaust fluid supply.
NOTICE
All valves in the fuel return line must be open and fuel
supply lines must be open. Damage to the fuel sys-
tem can occur if fuel lines are closed with the engine
in operation.
If the engine has not been started for several weeks,
fuel may have drained from the fuel system. Air may
have entered the filter housing. Also, when fuel filters
have been changed, some air pockets will be trapped
in the engine. In these instances, prime the fuel
system. Refer to the Operation and Maintenance
Manual, "Fuel System - Prime" for more information
on priming the fuel system. Also, check that the fuel
specification is correct and that the fuel condition is
correct. Refer to the Operation and Maintenance
Manual, "Fuel Recommendations".
Engine exhaust contains products of combustion
which may be harmful to your health. Always
start and operate the engine in a well ventilated
area and, if in an enclosed area, vent the exhaust
to the outside.
• Do not start the engine or move any of the controls
if there is a "DO NOT OPERATE" warning tag or
similar warning tag attached to the start switch or
to the controls.
• Reset all of the shutoffs or alarm components.
• Ensure that any driven equipment has been
disengaged. Minimize electrical loads or remove
any electrical loads.
Cold Weather Starting
i05844893
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
The ability to start the engine will be improved at
temperatures below −18 °C (0 °F) from the use of a
jacket water heater or extra battery capacity.
When Group 2 diesel fuel is used, the following items
provide a means of minimizing starting problems and
fuel problems in cold weather: Engine oil pan
heaters, jacket water heaters, fuel heaters and fuel
line insulation.
Use the procedure that follows for cold weather
starting.
Note: Do not adjust the engine speed control during
start-up. The electronic control module (ECM) will
control the engine speed during start-up.
1. Disengage any driven equipment.
Note: During key ON, the indicator lamps will be
illuminated for 2 seconds in order to check the lamp
operation. If any of the indicator lamps do not
illuminate check the bulb. If any indicator lamps stay
illuminated or flash, refer to Troubleshooting,
"Indicator Lamp Circuit - Test".
2. Turn the keyswitch to the RUN position. Leave the
keyswitch in the RUN position until the warning
light for the glow plugs is extinguished.
3. When the warning light for the glow plugs is
extinguished, turn the keyswitch to the START
position in order to engage the electric starting
motor and crank the engine.
Note: The operating period of the warning light for
the glow plugs will change due to the ambient air
temperature.
Do not engage the starting motor when flywheel is
turning. Do not start the engine under load.
If the engine fails to start within 30 seconds, release
the starter switch or button and wait two minutes to
allow the starting motor to cool before attempting to
start the engine again.
4. Allow the keyswitch to return to the RUN position
after the engine starts.
