Prepare Machine for Maintenance

Before performing maintenance on machine:

1. Unload dump body.

2. Wash machine.

3. Park machine on firm, level ground. Steer machine to straighten frames.

4. Install articulation safety lock bar.

5. Fully lower dump body, unless specifically instructed otherwise in a maintenance procedure. If dump body must be raised, install dump body prop.

6. Stop engine and engage park brake.

7. Remove key from key switch and attach a DO NOT OPERATE sign to steering wheel.

8. Relieve hydraulic pressure:

   1. Turn steering wheel back and forth 3 times.

   2. If dump body is fully lowered, hydraulic pressure is automatically relieved. If dump body is raised and dump body prop is installed, move dump body control lever forward and rearward 3 times to ensure that the weight of the dump body is securely settled onto the dump body prop.

9. If servicing the pneumatic system, relieve pneumatic pressure.

10. CAUTION: Prevent rollaway. Install wheel chocks on at least one axle.

    Install wheel chocks to ensure that machine cannot move backward or forward during service.

11. CAUTION: Be careful when working with hot equipment and fluids. Hot equipment and fluids can cause burns to unprotected skin.

    Allow time for the engine and all fluids to cool, unless specifically instructed otherwise in a maintenance procedure.

NOTE: The air conditioning system is charged with gas under pressure. Air conditioning service should be performed only by a qualified technician with proper equipment. (See your authorized dealer.)
