SAFETY
PRECAUTIONS ON MAINTENANCE
Release pressure before working on the
hydraulic system
Oil may spurt out if caps or filters are
removed or pipes are disconnected before
releasing the pressure in the hydraulic
system.
• Gradually loosen the vent plug to relieve
tank pressure.
• When removing plugs or screws, or when
disconnecting hoses, stand to the side and
loosen them slowly to gradually release the
internal pressure before removing.
• Oil or plug may spurt out according to the
pressure in the travel motor case. Loosen
the plug slowly and release the internal
pressure.
Be careful with debris when the hammer
is being used
When using a hammer, pins may fly out or
metal particles may be scattered. This may
lead to serious injury.
• If hard metal parts such as pins, bucket
teeth, side cutter or bearings are hit with a
hammer, wear protective gear such as
safety goggles and gloves.
• When hitting pins or bucket teeth, always
check that there is no one in the
surrounding area.
