2-14.
SPECIAL OPERATING PROCEDURES.
a. Extreme Cold Weather Conditions. Be careful when placing the trailer in motion after a shutdown. Congealed
lubricants can cause part failure. Tires may be frozen to the ground. If tires were under-inflated, they may have flat
spots. If brake shoes are frozen to the brake drums, use a torch to heat drums. Refer to FM 9-207 and FM 21-305 for
special instructions on driving hazards that may be encountered during extreme cold weather conditions.
b. Extreme Hot Weather Conditions. Do not park the trailer in the sun for long periods of time as the heat and
sunlight will shorten the life of the tires and lead to deterioration of painted surfaces. If possible, park the trailer under
cover to protect it from sun, sand and dust. Cover inactive trailer with tarpaulins if no other suitable shelter is available.
Metal parts of the trailer, inactive for long periods in hot, humid weather, are subject to rapid rusting and accumulation of
fungi growth. Frequently inspect, clean, and lubricate to prevent excessive deterioration.
c.
Operation on Unusual Terrain.
(1) Operation under extremely sandy conditions necessitates frequent inspection, cleaning and lubrication of the
chassis working parts.
