OPERATION IN EXTREME HEAT
Do not park the semitrailer in sunlight for long periods of time. 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.
2. Tires may freeze to the ground or have a flat spot if underinflated.
3. Brakeshoes may freeze to the brakedrums and need to be heated to prevent damage to
mating surfaces.
4 Refer to FM 9-207 and FM 21-305 for special instructions on driving hazards in extreme cold.
5. When parking short term, park in a sheltered area out of the wind.
6. For parking long term, If high, dry ground is not available, place a footing of planks or brush under semitrailer
wheels and landing gear.
7. Remove all built-up ice, snow, and mud as soon as possible after use.
8. Cover and shield semitrailer with canvas covers, if available. Keep ends of covers off the ground to keep them
from freezing to the ground.
OPERATION IN RAINY OR HUMID CONDITIONS
Inspect, clean, and lubricate equipment often to stop rust and fungus.
OPERATION IN SANDY OR DUSTY AREAS
CAUTION
Do not tow, pull, or push semitrailer by the rear bumper. Damage may result.
1. Clean, inspect, and lubricate more often in dusty or sandy areas.
