This section contains instructions for safely operating the dolly set under unusual conditions. In addition to
normal preventive maintenance services, special care must be taken to keep the dolly set operational in extreme
temperatures and humidity.
2-22. OPERATION IN EXTREME COLD.
a.
Special care must be taken when operating dolly sets in cold weather. Refer to FM 9-207 for operation
and maintenance of ordnance material in cold weather. Also refer to FM 21-305, which is a manual for the wheeled-
vehicle driver.
b.
Refer to Chaper 3, Section I, for proper lubrication during extreme cold weather.
c.
Care must be taken when handling electrical cables. Extreme cold weather can cause insulation
material on electrical wire to crock, causing short circuits. Construction materiel may become hard, brittle, and easily
damaged or broken.
d. When parking for any period of time in temperatures below O°F (-18°C), park in a sheltered area out
of the wind and clean off any buildup of ice or snow. Place footing of planks or brush under tires to prevent them from
freezing to ground. Make sure tires are properly inflated (para 1-10). Under inflated tires will freeze, resulting in flat
Spots.
2-23. OPERATION IN EXTREME HEAT.
a.
Refer to Chapter 3, Section I, for proper lubrication during extreme heat conditions.
b. Do not park dolly set in sunlight for long periods of time. Heat and sunlight shorten tire lie.
c.
Shelter or cover dolly set with canvas, if available.
d.
When humid, frequently inspect, clean, and lubricate to prevent rapid rusting and growth of fungi.
2-24. OPERATION IN MUD.
Immediately after operation in mud, thoroughly clean, inspect, and lubricate if tactical situation permits
(Chapter 3, Section l).
b. Pack wheel bearings as required (Chapter 3, Section I).
