Protecting Your Truck When You Park It

TM 9-2320-273-10

PARK YOUR TRUCK UNDER COVER, IF POSSIBLE. This will help protect it

against the effects of sun, sand, and dust. IF NO SHELTER IS AVAILABLE,

COVER TRUCK WITH TARPAULINS. If You don't have enough tarps to cover

the entire truck, ARRANGE TARPS AROUND ENGINE COMPARTMENT AND

OVER RADIATOR to keep out sand and dust. COVER WINDOW GLASS to

protect against sandblasting.

CHECK TIRES and make sure all tires are inflated to proper pressures.

CHECK FREQUENTLY FOR RUST AND FUNGUS GROWTH, both of which

are common problems in hot, humid weather. CLEAN AND LUBRICATE YOUR

TRUCK to help prevent deterioration.

2-23. Unusual Terrain.

BECOME FAMILIAR WITH THE PROCEDURES IN FM 21-305 for driving on unusual

terrain. USE THESE PROCEDURES ALONG WITH THE FOLLOWING GUIDELINES

WHEN YOU OPERATE THE M916 thru M920 OFF THE ROAD.

NOTE

The M915 is not designed or intended for off-road use.

However, if you should find the adverse conditions

described in this paragraph unavoidable, the recommend-

ed procedures given should be applied.

CAUTION

Do not use pusher axle during off-highway operations,

RELIEVE THE AIR PRESSURE LOAD ON THE PUSHER AXLE AND RAISE

THE PUSHER AXLE (M917, M919, M920). This will increase traction by shift-

ing weight to the driving axles.

In areas WHERE THE GROUND SURFACE PROVIDES POOR TRACTION,

MOVE THE DIFFERENTIAL LOCK/UNLOCK CONTROL LEVER TO THE

LOCK POSITION (See instructions in paragraph 2-13).

When you engage the locking system, driving axles receive equal torque.

Use the differential lock/unIock control as needed for better traction. Disengage

differential lockup when conditions are back to normal. For instructions on oper-

ating the inter-axle differential lockup system refer to paragraph 2-13.
