TM 9-2320-211-10-1
(5) If one or more tires become stuck, use another truck to tow or winch
the stuck truck. If a truck is not available, jack up stuck truck and put planking
(6) After operating truck on muddy or snowy surfaces, clean ice, snow, or
mud from wheels, axles, radiator core, engine compartment steering knuckles and
arms, air cleaner intake, and electrical connections.
b. Operation on Hard Baked Sand. 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.
c.
Operation on Ice.
(1) General. Skidding and loss of steering control are the main troubles
found when driving on icy roads. Due to lack of traction, the truck may continue in
a straight direction no matter which way you turn the wheels. When the wheels
reach a point where you get traction back, the truck may veer sharply to left or
right or stall.
(2) Skidding. When the rear end of the truck skids to either right or left,
instantly turn the front wheels in the same direction in which the rear end is skidding.
Take your foot off the accelerator pedal but do not step down on the clutch pedal.
Step down on the brakes very lightly.
d. Dusty or Sandy Roads.
(1) When operating truck on dusty or sandy terrain, clean air filter daily.
Operating on Rocks and Boulders.
e.
CAUTION
Too much pressure in tires will cause more shock
through the moving truck. Not enough pressure
in tires can cause internal breaking of the tires
or damage to the tube.
(1) Refer to table 2-5 and fill the tires properly.
(2) Check tire pressure when tires are cold.
(3) Do not let out air when tires are hot.
f.
Operation in High Altitudes.
(1) High altitude operation requires careful maintenance of the cooling
system. As you go to a higher altitude, the boiling point of your coolant will become
lower. The pressurized cooling system of your truck will operate at 220F when taken
care of in the right way.
(2) Check all hose connections for leaks daily and be sure that radiator cap
is closed properly.
