OPERATE IN EXTREME COLD
1.
General.
a.
Extreme cold causes many problems:
(1)
Lubricants thicken or congeal.
(2)
Batteries may freeze or lose their electrical efficiency.
(3)
Fuel may not readily atomize for combustion.
(4)
Various materials will become hard, brittle, and easily damaged.
(5)
The cooling system requires adequate protection from extreme cold.
(6)
Fuels, lubricants, and antifreeze compounds require special storage, handling, and use.
(7)
Water left undrained in tank and in water pump may freeze.
b.
Refer to FM 9-207 for additional information.
c.
When starting out in extreme cold, follow these procedures:
(1)
Be careful when you first start machine. Use appropriate engine starting procedure and allow engine time
to reach operating temperature. Be alert that tires may be frozen to ground.
(2)
Start driving very slowly for about 100 yards (91.4 m). If a problem is noted, notify Unit Maintenance as
required.
d.
When parking, follow these procedures:
(1)
If machine will be parked for a short period, park in a sheltered area out of wind. If shelter is not available,
park machine so that radiator does not face into the wind.
(2)
If machine will be parked for a long shutdown period, try to park on high ground and use planks or brush
to make a raised and relatively dry surface. Keep tires out of snow, water, ice, and mud, if possible.
(3)
Clean snow, ice, and mud from machine as soon as possible after shutdown.
(4)
If machine will be parked for a long period of time, have Unit Maintenance prepare machine for storage
(TM 5-3800-205-23-1 and TM 5-3800-205-23-3).
(5)
Ensure tires are properly inflated.
e.
Ensure water distributor tank and water pump are thoroughly drained and dried to prevent freeze damage. Refer to
OPERATE IN EXTREME HEAT
1.
General. During very hot weather, operating procedures may require altering to prevent machine overheating. Avoid
continuous high engine RPM's, and minimize operation in soft terrain.
Driving Machine.
2.
a.
Monitor EMS and engine coolant temperature gage. Stop if EMS signals an alert or if temperature is unusually
high. Allow machine to cool down.
b.
Check cooling system, engine air precleaner, air cleaner, air cleaner restriction indicator, engine oil level, and radi-
ator fins frequently. Perform necessary services and notify Unit Maintenance of any unusual readings or problems.
c.
Notify Unit Maintenance to shorten differential and final drive oil change interval.
