a . Operation.
(1) Be careful when placing the semitrailer in motion after a shutdown. Congealed lubricants can cause
part failure.
(2) Tires may be frozen to the ground or with a flat spot if they were under-inflated.
(3) Brakeshoes maybe frozen to the brake drums and will require preheating by using a torch to
avoid damage.
(4) Refer to FM 9-207 and FM 21-305 for special instructions on driving hazards in snow and ice that
may be encountered during extremely cold weather conditions.
i
b. At-Halt Parking.
(1) For short shutdown periods, park in a sheltered spot out of the wind.
(2) For long shutdown periods, if high dry ground is not available, prepare a footing of planks or
brush.
(3) Remove all built-up ice and snow as soon as possible after shutdown.
(4) Cover and shield the semitrailer with canvas covers but keep the ends of the covers off the ground
to prevent them from freezing to the ground.
2-41. OPERATION IN EXTREME HEAT
a. Do not park the semitrailer in the sun for long periods of time as heat and sunlight will shorten the life
of the tires.
b. Cover the semitrailer with canvas to protect it from heat, sun and dust.
