2-31. OPERATE IN MUD OR SNOW.
a. When operating forklift truck in mud, sand, or snow, extra care must be taken to prevent overheating of engine and
transmission due to greater resistance of ground surface. Use lowest range possible and closely monitor indicator lights.
b. If wheels start to spin, ease off accelerator pedal and attempt to regain traction.
a. Water obstacles can be forded to a depth of 15 in. (38.1 cm).
b. After fording, check all fluids for signs of contamination and for proper levels (see LO 10-3930-659-12).
2-33. OPERATE IN DUSTY OR SANDY AREAS.
Wen operating under desert conditions, also refer to paragraph 2-30.
a. General Guidelines.
(1) Dust and sand act as contaminants and abrasives which increase wear and damage.
(2) Keep equipment lubricants clean. Lubricate enclosed seals through grease fittings more often, adding
lubricant until clean lubricant comes out. Wipe clean all lubricating tools and lubrication points before
lubricating. Wipe clean outside of seals and grease fittings after lubrication. Check that seals and fittings are
(3) Oils and grease act as a magnet for dust or sand and create sludge that clogs, damages, and increases wear
on parts. Keep lubrication of exposed bearing surfaces to a minimum and use only what is absolutely
necessary to reduce friction.
(4) Check filters daily and keep filters clean. Clean air filters once daily. Check air system components for
damage frequently so that engine will not be contaminated by dust or sand.
(5) Do not let sand build up in skid plates. When combined with condensation or oil, sand can cause jamming of
(6) Keep fuel clean. When refueling, use a filter. Wipe around fill cap before removing, wipe nozzle clean before
inserting, and cover exposed area during filling.
