PRECAUTIONS FOR MAINTENENCE
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.
PRECAUTIONS FOR WORK UNDER MACHINE AND WORK EQUIPMENT
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 off the ground and the machine is sup-
ported only by the work equipment. If the control levers are
touched by mistake, or there is a hazard to the hydrauli-
cline, the work equipment or the machine may suddenly
descend. This is extremely dangerous. Never work under
the machine if the machine is not properly supported by
blocks or stands.
NOISE
If the noise from the machine is too loud, it may cause temporary or permanent hearing problems.
When carrying out maintenance of the engine and you are exposed to noise for long periods of time, wear ear cov-
ers or ear plugs while working.
PRECAUTIONS 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 fol-
lows.
If hard metal parts such as pins, or bearings are hit with a
hammer, there is a hazard that pieces might be scattered
and cause injury. Always wear safety goggles and gloves.
When hitting pins, 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.
If pins are hit with strong force, there is a hazard that the pin may fly out and injure people in the surrounding
area.
