Stopping the Truck and Shutting Down the Engine.

TM 9-2320-273-10

TO ADJUST LOAD ON THE PUSHER AXLE:

Rotate the CONTROL PRESSURE knob right (toward +) until the pressure gage

indicates the proper pressure setting for the desired load. Refer to the pusher axle

calibration chart located in the glove compartment. Tighten the setscrew, in the

center of the knob, to lock the CONTROL PRESSURE knob at the pressure

selected. With the setscrew tightened at a particular setting, the CONTROL PRES-

SURE knob can be closed (toward ) and reset to the previous setting.

TO RAISE THE PUSHER AXLE:

Set the axle raise/lower control at the AXLE LIFT position. This should be done

when turning sharp corners to shorten the turning radius and avoid dragging the

tires. This can be done with the vehicle in motion.

2-14. Stopping the Truck and Shutting Down the Engine.

Before shutting down the engine, idle it at reduced speed

(550-650 rpm) at no-load for 3 minutes to allow turbo-

charger to slow down. Cooling down time will depend

on how hard the engine has been worked.

a. LIFT YOUR FOOT OFF ACCELERATOR PEDAL and let reduction in engine

rpm and downshifting of transmission help to slow truck.

b. APPLY SERVICE BRAKES to bring truck to a normal, complete stop.

c. When truck is completely stopped, SHIFT TRANSMISSION TO NEUTRAL

AND APPLY PARKING BRAKES.

d. TURN OFF ENGINE RUN SWITCH.

2-15. Parking.

CAUTION

Do not park your truck on a steep grade. Even though

the parking brake holding capability exceeds federal safety

standards, it is never good practice to park a heavy truck

on a steep slope.

a. Stop truck.

b. Pull PARKING BRAKE control knob
