OPERATION IN EXTREME HEAT AND HIGH HUMIDITY
1. Refer to WP 0039 for proper lubrication during extreme heat conditions. Adequate lubrication is
essential. Extreme heat will cause oil films to evaporate, resulting in inadequate lubrication.
2. Cover inactive towing device 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
3. If inactive for long periods in hot, humid weather, towing device is subject to rapid rusting and
accumulation of fungi growth. Frequently inspect, clean, and lubricate to prevent excessive
OPERATION IN SANDY OR DUSTY AREAS
1. Inspect, clean, and lubricate towing device frequently when operating in dusty or sandy areas.
Refer to WP 0039 for proper lubrication instructions.
2. 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.
OPERATION IN MUD AND SNOW
Refer to FM 21-305 for special instructions for operation in snow.
1. Frequently clean, inspect, and lubricate towing device. Refer to WP 0039 for proper lubrication
2. After each operation remove ice, snow, and mud from underneath towing device and from hoses,
lines, tubes, and electrical connections.
OPERATION IN SALTWATER AREAS
1. Wash salt deposits from all equipment with fresh water.
2. Moist and salty areas can destroy the rust-preventative qualities of oils and greases. When
equipment is active, exposed surfaces should be cleaned and lubricated daily. Refer to WP 0039
for proper lubrication in high humidity and saltwater areas.
3. When equipment is inactive, unpainted parts should be coated with lubricating oil (refer to WP 0039).
All covers and caps should be in place.
