SAFETY
Be careful with oil internal pressure
Pressure is maintained in the hydraulic circuit
long after the engine has been shut down.
• Completely relieve the internal pressure
before performing maintenance work.
PRECAUTIONS ON MAINTENANCE
AG7A083
• The hydraulic oil is high enough pressure to
penetrate the skin or eyes and cause
serious injury, blindness or death.
Remember that the hydraulic oil escaping
from a small hole is almost invisible. When
checking for leaks, wear protective goggle
and thick gloves, and use a paperboard or
plywood to keep your skin from oil
spurting.
If oil penetrates the skin, it must be
surgically removed within a few hours by a
doctor familiar with this type of injury.
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 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.
