GENERAL
This section contains instructions for safely operating the M101 and M116 Series trailers under unusual conditions.
In addition to normal preventive maintenance, special care must be taken in regard to cleaning and lubrication to
keep the trailers operational in extreme temperatures and humidity. Proper cleaning, lubrication, storage, and
handling ensure proper operation and function and also guard against excessive wear.
Chronic failure of materiel resulting from exposure to extreme conditions must be reported in accordance with
DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual.
OPERATION IN EXTREME COLD
1.
For proper lubricants to use in extreme cold weather conditions, refer to the lubrication instructions in
(WP
0077).
2.
For special instructions on driving hazards that may be encountered during extreme cold weather conditions,
refer to Operation and Maintenance of Ordnance Materiel in Cold Weather FM 9-207 and Manual for the
Wheeled Vehicle Operator TC 21-305-20.
3.
Extreme cold can cause insulation material on electrical harnesses and wires to crack, causing short circuits.
Other materials can become hard, brittle, and easily damaged or broken.
4.
Make sure tires are properly inflated (WP
0002). Tires may freeze to the ground or have flat spots
if underinflated.
5.
Brake shoes may freeze to the brake drum and will require preheating to prevent damage FM 9-207.
END OF TASK
OPERATION IN EXTREME HEAT
1.
For proper lubrication during extreme heat conditions, refer to (WP
0077). Adequate lubrication is essential.
Extreme heat will cause oil films to evaporate, resulting in inadequate lubrication.
2.
Keep tires covered from direct sunlight to prevent increases in air pressure and deterioration of rubber.
