2-35. OPERATION IN DUSTY OR SANDY AREAS

a. General. Vehicles operating in dusty or sandy areas require frequent servic-

ing of the air cleaner, cooling system, and lubrication points. Operators should be

alert to engine overheating. If engine overheating occurs, refer to para. 2-34b,

step 5.

b. Before Operation. Perform steps in para. 2-34b.

c. Driving Vehicle.

(1) Start engine (para. 2-12).

NOTE

When driving on hard-baked sand, try not to break through the

crust. A roadbed of canvas or planking should be set down for

short distances.

(2) Place vehicle in motion (para. 2-15).

(3) If vehicle is to be operated in extreme heat, perform steps in para. 2-34c.

CAUTION

Do not attempt to jump vehicle out of deep sand with quick trans-

mission gear changes. Doing this may result in damage to equip-

ment.

(4) If vehicle becomes stuck in deep sand, use second vehicle with winch for

recovery operation (para. 2-18).

d. Stopping or Parking.

(1) Park vehicle in a sheltered area out of blowing dust or sand whenever

possible. If sheltered area is not available, park so vehicle does not face into wind.

(2) If sheltered area is not available, cover vehicle with paulin. When entire

vehicle cannot be covered, protect windows, cab, and engine compartment with

paulin to prevent entry of sand or dust.

(3) Stop vehicle and engine (para. 2-16).
