Operation in
2-16. GENERAL.
This section contains instructions for safely operating the trailers under unusual conditions. In addition to
normal preventive maintenance service, special care must be taken to keep the trailers operational in extreme
temperatures and humidity.
2-17. OPERATION IN EXTREME COLD.
a. Special care must be taken when operating the trailers in cold weather. Refer to FM 9-207 for
information regarding the water tank trailer. Refer to FM 21-305 for special instructions for all trailers.
b. Refer to Chapter 3, Section I for proper lubrication during extreme cold weather.
c. Care must be taken when handling cables. Extreme cold weather can cause insulation material on
electrical wire to crack, causing short circuits. Construction material may become hard, brittle, and easily
damaged or broken.
d. When parking for any period of time in temperature below 0F (-18C), parkin a sheltered area out
of the wind and clean off any buildup of ice or snow. Place a footing of planks or brush under tires and adjustable
caster assembly to prevent them from freezing to the ground. Ensure that the tires are properly inflated
(para 1-10). Underinflated tires will freeze, resulting in
flat spots.
e. The following steps should be followed for the M107 Series Water Tank Trailers:
(1) Water trailers equipped with an aluminum water tank body may use the M67 Immersion Heater
to prevent contents from freezing. Refer to TM5-4540-202-12&P for Installation, operation, and maintenance of
the M67 Immersion Heater.
(2) Drain water from piping, valves, and faucets during periods of inactivity by closing discharge
valve and opening manifold valve and all faucets (para 2-14).
(3) In areas where temperatures will drop below 32F (0C), manhole cover should be tightly
closed.
2-18. OPERATION IN EXTREME HEAT.
a. Refer to Chapter 3, Section I for proper lubrication during extreme heat conditions.
b. Do not park the trailer in sunlight for long periods of time. Heat and sunlight shorten tire life.
c. Shelter or cover the trailer with canvas, if available.
