GENERAL
This WP contains instructions for safely operating the trailer under unusual conditions.
In addition to normal preventive maintenance service, special care in cleaning and lubrication must be
observed where extreme temperature, humidity, and terrain conditions are present or anticipated. Proper
cleaning, lubrication, storage, and handling of fuels and lubricants not only ensure proper operation and
functioning, but also guard against excessive wear in the working parts and deterioration of materials.
FM 55-30 contains instructions on driver selection, training, and supervision. FM 21-305 prescribes
special driving instructions for operating wheeled vehicles under unusual conditions. A detailed study of
these manuals is essential for the use of this trailer under unusual conditions.
When chronic failure of the trailer results from exposure to extreme conditions, report the condition on SF
368.
OPERATION IN EXTREME COLD
CAUTION
To ensure
equipment
is not
damaged,
approved
practices
and
precautions must be followed.
1.
Extensive preparation of materials scheduled for operation in cold is necessary. Generally, extreme
cold causes lubricants to thicken or congeal, cracks insulation causing electrical short circuits, and
causes various construction materials to become hard, brittle, and easily damaged or broken.
2.
Operator must always be on alert for indications of the effect of cold weather on trailer.
3.
Use caution when placing vehicle in motion after a shutdown. Congealed lubricants may cause
failure of parts. Tires frozen to the ground or frozen to shape of flat spot while under-inflated must
be considered. One or more brakeshoes may be frozen fast and require preheating to avoid
damage to towing vehicle clutch surfaces.
4.
Refer to WP 0018 00 for proper lubrication during extreme cold weather.
5.
Refer to FM 9-207 for description of operations in extreme cold.
6.
Immediately after each operation, remove snow, ice, and/or mud, thoroughly clean, inspect, and
lubricate trailer if tactical situation permits. Upon completion of this operation, refer to WP 0017 00,
Table 1 (Operator/Crew PMCS), for “After” procedures to be performed.
7.
At halt or parking:
a.
When halted for a short shutdown period, park trailer in a sheltered spot out of wind. If no
shelter is available, park so rear of trailer faces into wind. For long shutdowns, if high and dry
ground is not available, prepare a footing of planks or brush.
b.
Immediately after each operation, remove snow, ice, and/or mud, thoroughly clean and
inspect trailer if tactical situation permits. Upon completion of this operation, refer to WP 0017
00, Table 1 (Operator/Crew PMCS), for “After” procedures to be performed.
