• BLEED all air pressure from system components (refer to the
Maintenance Section of this manual.)
• TURN OFF all air and electric supplies and all accessory
equipment at the machine.
• DISCONNECT AND LOCK OUT electrical and pneumatic
power, and attach warning tags to the disconnect switch and air

When you need to perform maintenance or repair work on a loader
above floor level, use a solid platform or a hydraulic elevator. If
there is a permanently installed catwalk on your loader, use it. The
work platform should have secure footing and a place for tools and
parts. DO NOT climb on loaders, machines, or work from
ladders.
If you need to repair a large component, use appropriate handling
equipment. Before you use handling equipment (portable “A”
frames, electric boom trucks, fork trucks, overhead cranes) be sure
the load does not exceed the capacity of the handling equipment or
cause it to become unstable.
Carefully test the condition of lifting cables, chains, ropes, slings,
and hooks before using them to lift a load.
Be sure that all non-current carrying parts of electrical apparatus,
electrical component enclosures, and the loader frame are correctly
connected to earth ground with an electrical conductor that
complies with current codes. Install in accordance with national
and local codes, which apply.
When you have completed the repair or maintenance procedure,
check your work, remove your tools, rigging, and handling
equipment.
Do not restore power to the loader until all persons are clear of the
area. Start and run the loader until you are sure all parts are
functioning correctly.
BEFORE you turn the loader over to the operator for production,
verify all guards and safety devices are in place and functioning
properly.
