OPERATION IN HIGH HUMIDITY AND SALTWATER AREAS

TM 9-2330-202-14&P

2-20.

OPERATION IN HIGH HUMIDITY AND SALTWATER AREAS.

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 Appendix I for proper lubrication in high

humidity and saltwater areas.

When equipment is inactive, unpainted parts should be coated with grease (Item 7, Appendix F). All covers and

caps should be in place.

OPERATION IN MUD AND SNOW.

After operation in mud or snow, have Unit maintenance pack wheel bearings as required (refer to Appendix I).

Refer to FM 21-305 for special instructions on driving hazards in snow. For better traction, reduce air pressure to

25 psi (174 kPa).

If one or more tires sink into mud or snow, it may be necessary to raise the tire and insert planking or matting

beneath it.

Immediately after operation in mud and snow, thoroughly clean, inspect, and lubricate if tactical situation permits.

Refer to Appendix I for proper lubrication instructions.

OPERATION IN DUSTY OR SANDY AREAS.

Inspect, clean, and lubricate frequently when operating in sandy or dusty areas. Refer to Appendix I for proper

lubrication instructions.

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.

When beginning operation in dusty or sandy areas, remove lubricants from exposed components, such as landing

gear, if tactical situation permits. Grease and oil will cause dust and sand to accumulate and act as an abrasive,

which will cause rapid wear.

Reduce tire pressure to 30 psi (207 kPa) for emergency use on beach or desert sand. Return tire pressure to

normal after emergency operation (para 1-15).

OPERATION IN ROCKY TERRAIN.

Use extreme caution when operating in rocky terrain. Make sure tires are fully inflated to minimize damage to tires
