Starting the Engine
5. Repeat step 2 through step 4 if the engine fails to
start.
Note: After starting, the engine may be held at low
speed for a duration between 1 and 60 seconds to
allow engine systems to stabilize. The duration will
depend on ambient temperature, time since last run
and other factors. The glow plug warning lamp will
flash to indicate that the engine has been held at low
speed.
6. The engine should not be raced to speed up the
warm-up process. Allow the engine to idle for 3 to
5 minutes, or allow the engine to idle until the
water temperature indicator begins to rise. When
idling after the engine has started in cold weather,
increase the engine rpm from low idle to 1200 rpm.
This operation will warm up the engine more
quickly.
7. Operate the engine at low load until all systems
reach operating temperature. Check the gauges
during the warm-up period.
Following a cold start, white vapor can be seen from
the tailpipe. This vapor is normal and caused by
condensation leaving the exhaust system after
warming up. The white vapor should clear following
working of the engine.
Starting the Engine
Note: Do not adjust the engine speed control during
start-up. The electronic control module (ECM) will
control the engine speed during start-up.
Starting the Engine
1. Disengage any equipment that is driven by the
engine.
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.
Note: If the keyswitch has been left in the RUN
position for a long period of time without engaging the
electric starting motor, turn the keyswitch from the
RUN position to the OFF position and then back to
the RUN position to reactivate the glow plug preheat
stage.
Note: During the key on, the indicator lamps will be
illuminated for 2 seconds to check lamp operation. If
any of the lamps do not illuminate, check the bulb. If
any indicator lamps stay illuminated or flash, refer to
Troubleshooting, "Indicator Lamp Circuit - Test".
3. When the warning light for the glow plugs is
extinguished, turn the keyswitch to the START
position 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 temperature of
the engine.
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.
5. Repeat step 2 through step 4 if the engine fails to
start.
6. After starting, the engine may be held at low speed
for a duration between 1 and 60 seconds to allow
engine systems to stabilize. The duration will
depend on ambient temperature, time since last
run and other factors. The glow plug warning light
will flash to indicate that the engine is being held at
i08165241
low speed in some applications.
Starting with Jump Start
Cables
(Do Not Use This Procedure in
Hazardous Locations that have
Explosive Atmospheres)
The connection of battery cables to a battery and
the disconnection of battery cables from a battery
may cause an explosion which may result in in-
jury or death. The connection and the disconnec-
tion of other electrical equipment may also cause
an explosion which may result in injury or death.
The procedures for the connection and the dis-
connection of battery cables and other electrical
equipment should only be performed in a nonex-
plosive atmosphere.
