Practice Safe Maintenance
To avoid accidents:
Understand service procedures before starting work.
Keep the work area clean and dry.
Do not spray water or steam inside cab.
Never lubricate or service the machine while it is moving.
Keep hands, feet and clothing away from power-driven
parts.
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.
4. Place the F-N-R lever in the neutral, and put the brake
switch in the P (parking brake) position.
5. Turn auto-idle switch OFF.
6. Run the engine at slow idle speed without load for 5
minutes.
7. Turn key switch to OFF to stop engine.
8. Remove the key from the key switch.
9. Close windows, roof vent, and cab door.
10. Lock all access doors and compartments.
11. Secure the wheels with wedges.
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.
Keep all parts in good condition and properly installed.
Fix damage immediately. Replace worn or broken parts.
Remove any buildup of grease, oil, or debris.
When cleaning parts, always use nonflammable
detergent oil. Never use highly flammable oil such as fuel
oil and gasoline to clean parts or surfaces.
Turn the battery disconnect switch to OFF before
adjusting the electrical systems or before performing
welding on the machine.
