OPERATION IN RAINY OR HUMID CONDITIONS

TM 9-2320-386-10

2-35. OPERATION IN DUSTY OR SANDY AREAS (Contd)

e. After Operation.

.WARNING.

Compressed air used for cleaning purposes will not exceed 30 psi

(207 kPa). Use only with effective chip guarding and personal pro-

tective equipment (goggles/shield, gloves, etc.).

(1) At end of daily operation, use low air pressure to remove all sand from

vehicle engine compartment, and areas around brakes, drums, and spring seats.

CAUTION

Do not allow dust or sand to enter fuel tank when filling. Doing

this may result in damage to fuel system.

(2) Fill fuel tank (TM 9-2320-361-10). Tighten filler cap securely after filling.

(3) Perform "after operation" PMCS (para. 2-8).

(4) Reinflate tires to proper operating pressure, if deflated (para. 2-19).

2-36. OPERATION IN RAINY OR HUMID CONDITIONS

a. General. Materiel inactive for long periods in hot, humid weather can rust

rapidly. Fungus growth may develop in the fuel tank as well as on canvas paulin,

seats, and other components. Frequent inspection, cleaning (refer to para. 2-7), and

lubrication are necessary to maintain the readiness of vehicles in rainy or humid

conditions. Fuel filters and air reservoirs must be drained frequently because of

high condensation in fuel and air systems.

.WARNING.

Do not operate vehicle on wet, smooth roads with lowered tire

inflation. Do not operate vehicle at too great a speed for road con-

ditions. Low tire inflation or excessive speeds may cause loss of

vehicle control on wet, smooth roads, resulting in injury or death

to personnel.

b. Before Operation. If vehicle is to be operated cross-country in heavy rain,

place ECU to "C" (cross-country) setting to deflate tire pressure to 73 psi (503 kPa)

c. Driving Vehicle. Perform steps in para. 2-33b.

d. After Operation.

(1) Perform "after operation" PMCS (para. 2-8).

(2) Notify unit maintenance to drain water from fuel tank. Fill fuel tank (TM

9-2320-361-10).

(3) Reinflate tires to proper operating pressure (para. 2-19).
