2-24. OPERATION IN EXTREME COLD
a.
Semitrailer.
(1) 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.
(2) Tires may be frozen to the ground or have flat spots if they were under-inflated when the semitrailer was
parked.
(3) Brake shoes may become frozen to the brake drums and will require preheating with a torch to avoid
damage.
(4) For short shutdown periods, park in a sheltered spot out of the wind.
(5) For long shutdown periods, if high dry ground is not available, prepare a footing of planks or brush.
(6) Cover or shield the semitrailer with canvas covers if available. Keep ends of covers off the ground to keep
them from freezing to the ground.
(7) Be careful when placing the semitrailer in motion after shutdown. Low temperatures can cause lubricants to
thicken or congeal. This can cause parts failure.
(8) Apply brakes to assure they are working before driving at normal speed.
b.
Water Distributor.
(1) Freezing water can damage pipes, pump body and valve bodies. If water must be transported in
temperatures below freezing, fill the tank, close the suction line valve, and drain all pump and discharge
piping.
(2) After use, be sure the tank and all piping are completely drained to prevent damage to equipment.
