PRACTICE SAFE MAINTENANCE
To avoid accidents:
•
Understand service procedures before doing 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 mov-
ing.
•
Keep hands, feet and clothing away from
power-driven parts.
Before servicing the machine:
1. Park the machine on a level surface.
2. Lower the bucket to the ground.
3. Turn the auto-idle switch off.
4. Run the engine at slow idle speed without load for 5
minutes.
5. Turn the key switch to OFF to stop engine.
6. Relieve the pressure in the hydraulic system by mov-
ing the control levers several times.
7. Remove the key from the switch.
8. Attach a “Do Not Operate” tag on the control lever.
9. Pull the pilot control shut-off lever to the LOCK posi-
tion.
10. Allow the engine to cool.
•
If a maintenance procedure must be performed with
the engine running, do not leave machine unattended.
•
If the machine must be raised, maintain a 90 to 110
q
angle between the boom and arm. Securely support
any machine elements that must be raised for service
work.
•
Never work under a machine raised by the boom.
•
Inspect certain parts periodically and repair or replace
as necessary. Refer to the section discussing that part
in the “MAINTENANCE” chapter of this 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 de-
tergent oil. Never use highly flammable oil such as
fuel oil and gasoline to clean parts or surfaces.
•
Disconnect battery ground cable (–) before making
adjustments to electrical systems or before performing
welding on the machine.
