OPERATE IN EXTREME COLD.
a.
General.
(1)
Extreme cold causes many problems:
(a)
Lubricants thicken or congeal.
(b)
Batteries may freeze or lose their electrical efficiency.
(c)
Fuel may not readily atomize for combustion.
(d)
Various materials will become hard, brittle, and easily damaged.
(e)
The cooling system requires adequate protection from extreme cold.
(f)
Fuels, lubricants, and antifreeze compounds require special storage,
handling, and use.
(2)
Refer to FM 9-207 for additional information.
(3)
Arctic Heater Kit. All vehicles assigned to arctic regions are equipped with
an auxiliary arctic heater kit which protects vehicle systems from freeze damage, enables
easier starting by providing engine block preheating, and boosts cab heat output. Refer to
subparagraph b for operation of arctic heater.
(4)
Starting Out.
(a)
Be careful when you first start your vehicle. Use cold weather
starting procedure (paragraph 2-12) and allow engine time to reach operating temperature
range of 120-140°F (48-59°C). Be alert that tires may be frozen to ground.
(b)
Start driving very slowly for about 100 yards (91.4 m). Be alert for
signs that tires may have flat spots or that one or more brake shoes may be frozen and
require preheating. Notify Unit Maintenance as required.
(5)
Parking.
(a)
If vehicle will be parked for a short period, park in a sheltered area
out of wind. If shelter is not available, park vehicle so it does not face into the wind.
(b)
If vehicle 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.
(c)
Clean snow, ice, and mud from vehicle as soon as possible after
shutdown.
(d)
If vehicle will be parked for a long period of time, have Unit
Maintenance remove and store batteries. Fill fuel tank to guard against condensation and
drain any accumulated water from air reservoirs and fuel filters.
(e)
Ensure tires are properly inflated.
