EXTREME COLD CONTINUED
Starting Procedures Machine Equipped with Arctic Kit
C AU T I O N
At temperatures nearing -40°F (-40°C), it is necessary to shut off the arctic heater at least
30 seconds before attempting to start the machine's engine. Failure to follow this caution
may result in internal damage to the heater or localized boiling of the coolant in the heater
body which may cause a heater hose to come off.
When ambient temperature is above 0°F (-18°C), do not crank engine for more than 30
seconds. Allow starting motor to cool for two minutes before cranking again or damage to
starting motor or batteries may result.
When ambient temperature is between -1°F (-18°C) and -25°F (-32°C), it may be
necessary to crank engine for up to 60 seconds.
When ambient temperature is between -26°F (-32°C) and -40°F (-40°C), it may be
necessary to crank engine for up to 120 seconds.
Shut down engine immediately if engine system indicator or action light indicator comes
on. Notify Field Maintenance. Failure to follow this caution may result in damage to engine
or other machine systems.

If engine coolant heater has not been started for several months, or if heater is being
started for the first time, it may take several attempts to start.
If engine coolant heater fails to start at first attempt, it will automatically attempt to start a
second time. If heater still does not start, it will shut down.
During operation, engine coolant heater continually senses supply voltage. If voltage is too
low or too high, heater will automatically shut down. If this occurs, notify Field Level
1. Activate engine coolant heater as follows:
a. Turn battery disconnect switch to ON position (WP 0004).
b. Activate engine coolant heater switch (WP 0004).
2. Allow heater to run up to 40 minutes.
3. Push engine coolant heater button to turn heater off, then wait at least 30 seconds.

At temperatures of less than -25°F (-32°C), be sure to keep starter engaged until engine
speed approaches 500 rpm. Multiple short (15-second) start attempts at cold
temperatures can result in engine bearing damage due to inadequate lubrication.
5. Check that engine oil pressure light on monitor system registers pressure within 10 seconds of engine starting.
6. Allow engine to idle for at least five minutes before moving machine.
