Before servicing the machine:
1. Park the machine on a firm, level surface.
2. Lower bucket to the ground.
3. Pull the pilot control shut-off lever to the LOCK position.

8. Remove the key from the key switch.
9. Close windows, roof vent, and cab door.
10. Lock all access doors and compartments.

 If a maintenance procedure must be performed with the
engine running, do not leave the machine unattended.
 If the machine must be raised, maintain a 90 to 110˚
angle between the boom and arm. Securely support any
machine elements that must be raised for service work.
 Inspect certain parts periodically and repair or replace as
necessary. Refer to the section discussing that part in the
"MAINTENANCE" chapter of operator's manual.
