SAFETY MAINTENANCE INFORMATION

PERSONNEL

Do not allow any unauthorized personnel into the area when servicing the machine. If necessary, employ a guard.

ATTACHMENTS

Appoint a leader before starting removal or installation
operations for attachments.
Place attachments that have been removed from the machine in
a stable condition so that they do not fall. And take steps to
prevent unauthorized persons from entering the storage area.

WORK UNDER THE MACHINE

If it is necessary to go under the work equipment or the machine
to carry out service and maintenance, support the work
equipment and machine securely with blocks and stands strong
enough to support the weight of the work equipment and
machine.
It is extremely dangerous to work under the machine if the track
shoes are lifted off the ground and the machine is supported
only with the work equipment. If any of the control levers is
touched by accident, or there is damage occurring to the
hydraulic piping, the work equipment or the machine will
suddenly drop. This is extremely dangerous. Never work under
the work equipment or the machine.

NOISE

When carrying out maintenance of the engine and you are exposed to noise for long periods of time, wear ear covers
or ear plugs while working.
If the noise from the machine is too loud, it may cause temporary or permanent hearing problems.

WHEN USING HAMMER

When using a hammer, pins may fly out or metal particles may be
scattered. This may lead to serious injury. Always do as follows.
If hard metal parts such as pins, bucket teeth, cutting edges, or
bearings are hit with a hammer, there is a hazard that pieces
might be scattered and cause serious personal injury or death.
Always wear safety glasses and gloves.
When hitting pins or bucket teeth, there is a hazard that broken
pieces might be sent flying and injure people in the surrounding
area. Always check that there is no one in the surrounding area.
There is a hazard that the pin hit with strong force may fly out and injure people in the surrounding area.
