2-24. OPERATION IN EXTREME COLD
(1) Extensive preparation of materiel scheduled for operation in extreme cold weather is necessary. Generally,
extreme cold causes lubricants to thicken or congeal, cracks insulation, causes electrical short circuits and various
construction materials to become hard, brittle, and easily damaged or broken.
(2) You, the operator, must always be on the alert for indications of the effect of cold weather on the semitrailer.
(3) You, the operator, must be very cautious when placing the vehicle in motion after a shutdown. Congealed
lubricants may cause failure of parts. Tires frozen to the ground or frozen to the shape of the flat spot while underinflated
must be considered. One or more brake shoes may be frozen fast and require preheating to avoid damage to the towing
vehicle clutch surfaces.
(4) Refer to FM 9-207 for description of operation in extreme cold.
b. At Halt or Parking.
(1) When halted for short shutdown periods, park semitrailer in a sheltered spot out of the wind. If no shelter is
available, park so that its rear faces into the wind. For long shutdown periods, if high and dry ground is not available,
prepare a footing of planks or brush.
(2) Clean all parts of the semitrailer of snow, ice and mud as soon as possible after operation. See PMCS,
