PRACTICE SAFE MAINTENANCE
To avoid accidents:
Understand service procedures before doing
work.
Keep 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 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
moving 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
position.
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 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 in the 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.
Disconnect battery ground cable (-) before
making adjustments to electrical systems or
before welding on the machine.
Illuminate your work area adequately but safely.
Use a portable safety light for working inside or
under the machine.
Make sure that the bulb is enclosed by a wire
cage.
The hot filament of an accidentally broken bulb
can ignite spilled fuel or oil.
