MALFUNCTION

TEST OR INSPECTION

CORRECTIVE ACTION

1. TIRE WEARING UNEVENLY

Step 1. Place blocks (6 by 6 by 18 inches wood blocks) at each wheel to prevent vehicle from moving.

Remove shipping lock pin from storage area under operator's seat (para 2-4b (1)) and install in chassis.

Ensure that parking brake is in released position.

WARNING

Before raising axle off ground, be sure that shipping lock pin is

installed. Failure to do so may cause vehicle to turn and slip off

jack or jack stands causing serious injury or death. If you are

injured by falling equipment, obtain medical aid immediately.

Raise one axle and wheels off ground.

Rotate wheel by hand; there should be a very slight drag on wheel.

Repeat above for remaining wheel and axle.
