SAFETY

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.

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, bucket teeth, cutting
edges, 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 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.
If pins are hit with strong force, there is a hazard that the pin may fly out and injure people in the surrounding
area.

WELDING WORKS

Welding operations must always be carried out by a qualified welder and in a place equipped with a proper equip-
ment. There is a hazard of fire or electrocution when carrying out welding, so never allow any unqualified person-
nel to carry out welding.

REMOVING BATTERY TERMINALS

When repairing the electrical system or when carrying out electrical welding, remove the negative (-) terminal of
the battery to prevent the flow of current.
