OPERATION IN EXTREME HEAT
Do not park the semitrailer in sunlight for long periods of time because effects of heat
and sunlight shorten the life of tires. If possible, shelter or cover semitrailer.
OPERATION IN EXTREME COLD
1.
Extreme cold can cause lubricants to thicken or congeal, insulation to crack and cause
electrical short circuits, and construction materials to become hard, brittle, and easily
damaged or broken.
Tires may freeze to the ground or have a flat spot if underinflated.
2.
Brakeshoes may freeze to the brakedrums and need to be heated to prevent damage to
3.
mating surfaces.
Refer to FM 9-207 and FM 21-305 for special instructions on driving hazards in extreme cold.
4.
When parking short term, park in a sheltered area out of the wind.
5.
For parking long term, if high, dry ground is not available, place a footing of planks or brush
6.
under semitrailer wheels and landing gear.
7.
Remove all built-up ice, snow, and mud as soon as possible after shutdown.
8.
Cover and shield the semitrailer with canvas covers if available. Keep ends of covers off of the
ground to keep them from freezing to the ground.
OPERATION IN RAINY OR HUMID CONDITIONS
Inspect, clean, and lubricate inactive equipment often to stop rust and fungus from getting on it.
OPERATION IN SANDY OR DUSTY AREAS
CAUTION
Do not tow, pull, or push semitrailer by the rear bumper. Damage may be caused.
1. Clean, inspect, and lubricate more often in dusty or sandy areas.
2. Reduce tire inflation to 40 psi (276 kPa) for operation in beach and desert sand.
3. Be sure to return tire air pressure to normal after sand operation (75 psi/517 kPa).
