SAFETY
Be careful with hot cooling systems
PRECAUTIONS ON MAINTENANCE
Do not remove the radiator cap or the drain
plug when the cooling water is hot. Stop the
engine and wait until the engine and the
cooling water cool. Then, slowly loosen the
radiator cap to release the internal pressure
and remove it.
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.
• 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.
• Immediately after the engine is stopped,
and while the safety lock lever is still in the
unlock position, turn the starter switch to
ON and move all the control levers and
pedals several times all the way in each
direction to release the pressure from the
working equipment circuitry.
• Press the air breather button to relieve the
internal pressure from the tank.
• 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.
