OPERATION IN EXTREME COLD CONTINUED
2. Cooling System.
WARNING
DO NOT service cooling system unless engine has cooled. This is a pressurized cooling
system, and escaping steam or hot coolant will cause serious burns.
DO NOT remove cooling system radiator cap when engine is hot. Allow engine to cool
down. Loosen cap to first stop and let any pressure out of cooling system, then remove
cap. Failure to follow this warning may cause serious burns.
Wear effective eye, glove, and skin protection when handling coolants. Failure to follow
this warning may cause injury to personnel.
a. Inspect loader for leaks and general condition.
b. Ensure hose clamps are tight.
c.
Check coolant level in sight gauge at top of radiator tank. If necessary, add coolant to correct level
d. Notify Field Maintenance if system needs service beyond adding coolant.
3. Fuel System.
WARNING
DO NOT smoke or permit any open flame in area of machine while you are servicing fuel
system. Be sure hose nozzle is grounded against filler tube during refueling to prevent
static electricity.
Operating personnel must wear fuel-resistant gloves when handling fuels. If exposed to
fuel, promptly wash exposed skin and change fuel-soaked clothing.
ALWAYS stop engine prior to refueling. If equipped with an arctic cold weather starting aid
system, turn arctic heater off.
Failure to follow these warnings may result in injury or death to personnel or damage to
equipment.
a. Do not allow fuel tank to remain partially empty in extremely cold weather. Fill fuel tank after each work
period to help avoid water condensation in tank (WP 0013).
b. Remove all ice and snow from around fuel filler opening before refueling.
c.
Regularly drain water and sediment from fuel/water separator.
4. Electrical System.
a. Inspect battery cables, wiring harnesses, and wiring.
b. Check for breaks or cracks caused by cold weather. Report any problems found to Field Maintenance.
c.
Save batteries. Use lights and other electrical equipment as little as possible when engine is not running.
5. Lubrication.
Use correct lubricants as specified (WP 0013) with the temperature range that applies to the lowest expected
ambient temperature.
