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
low speed in some applications.
Cold Weather Starting
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) by the use of a
jacket water heater or a battery with extra capacity.
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 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 cycle the keyswitch. Turn the
keyswitch to the OFF position and then 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 vary according 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.
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 of between 1 and 25 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 is being held at low
speed.
6. The engine should not be raced to speed up the
engine warming 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 1000 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 engine warming up period.
Following a cold start white smoke can be seen from
the tailpipe. This smoke is normal and caused by
condensation leaving the exhaust system after
warming up. The white smoke should clear following
working of the engine.
