OPERATION IN EXTREME HEAT AND HIGH HUMIDITY
1.
For proper lubrication during extreme heat conditions, refer to (WP 0093). Adequate lubrication is essential.
Extreme heat will cause oil films to evaporate, resulting in inadequate lubrication.
2.
Keep tires protected from direct sunlight to prevent increases in air pressure and deterioration of rubber.
3.
Cover inactive semitrailer with tarpaulins if they are available, and if there is no other available shelter. For
several hours each week, shake out and air canvas covers or other items subject to deterioration from
mildew or attacks by insects or vermin.
4.
If inactive for long periods in hot, humid weather, semitrailers are subject to rapid rusting and accumulation
of fungi growth. Frequently inspect, clean, and lubricate to prevent excessive deterioration.
END OF TASK
OPERATION IN SANDY OR DUSTY AREAS
CAUTION
Do not tow, pull, or push semitrailer by rear bumper. Failure to comply may result in
damage to, or destruction of, equipment or mission.
1.
Inspect, clean, and lubricate semitrailer frequently when operating in dusty or sandy areas. For proper
lubrication instructions, refer to (WP 0093).
2.
Reduce pressure to 70 psi (482.6 kPa) for operation on beach or desert sand.
3.
Make sure no dust or sand enters exposed mechanisms or lubrication fittings during inspections and repair
operations. Cover exposed parts with tarpaulins or other suitable cover during disassembly and assembly.
4.
Be sure to return tire pressure to normal 115 psi (792.93 kPa) for the M870A3 after operation in sand.
END OF TASK
OPERATION IN MUD AND SNOW
CAUTION
Do not tow, pull, or push semitrailer by rear bumper. Failure to comply may result in
damage to, or destruction of, equipment or mission.
NOTE
For special instructions for operation in snow, refer to FM 21-305.
1.
Frequently clean, inspect, and lubricate semitrailer. For proper lubrication instructions, refer to (WP 0093).
2.
Reduce tire pressure to 70 psi (482.6 kPa) while operating in soft mud, if practical.
3.
If one or more wheels sink into mud, you may need to jack up mired wheel and put planking or matting
under it.
4.
After each operation remove ice, snow, and mud from underneath semitrailer and from hoses, lines, tubes,
and electrical connections.
5.
Return tire pressure to normal 115 psi (792.93 kPa) after operation in mud.
