Safety precautions
The most important point in providing repair service is
safety. To ensure safety, observe the general cautions
described below.
- This manual is intended for properly trained and
equipped service technicians.
- Any work on the machine must be performed by the
trained personnel only.
- Carefully read this manual to thoroughly understand
the operation method before you operate or repair
the machine.
- Be sure to wear appropriate clothes and protectors,
such as safety boots, hard hat and goggles.
- Place the machine on level and solid ground, and
place chocks against the wheels to prevent move-
ment.
- Remove the cable from the battery before starting
the service work, and attach a "DO NOT OPERATE!"
tag to the steering wheel.
- Be sure to release the internal pressure before you
remove a pipe, such as the hydraulic oil, air, or
engine coolant pipe.
- Be sure to apply the articulation stopper before start-
ing work.
- While supporting the bottom of the chassis using a
jack, be sure to support the chassis using the blocks.
- When the boom or bucket is raised or when a unit is
lifted by a crane, be sure to place a stand or ade-
quate cribbing under the unit to prevent unexpected
dropping.
- Do not start to work in an enclosed area if adequate
ventilation is not provided.
- To remove a heavy unit (20 kg (40 lbs) or more), be
sure to use a crane or other lifting device.
- Just after stopping operation, be careful not to
directly touch a hot component. You may get burned.
- Contact tire manufacturer's local dealer for tire ser-
vicing and changing.
- Always store the tools in good condition, and use
them properly.
- Keep the work area clean. Clean up spills immedi-
ately.
- Avoid the use of flammable solvents and cleaners.
- When working outdoors keep work areas, ladders,
steps, decks and work platforms clear of snow, ice,
and mud.
- Use safe work platforms to reach higher areas of the
machine.
- Any technician that operates a refrigerant recovery
and recycling machine must first be certified through
an EPA approved testing program.

IMPORTANT
If a battery terminal is removed from a machine in
less than 30 seconds after the key is put into the
“OFF” position, it can corrupt the ECM program,
which can disable the engine. Always wait 1 full
minute to be sure to be past this “write to memory
function” prior to removing battery terminals.
