(9) Relieve hydraulic pressure
・
After stopping the engine, set the starter switch to the "ON"
position, move the safety lock lever to the "release" position,
and move the control levers for one or two minutes to relieve
pressure.
・
It is dangerous to replace or repair hydraulic hoses, joints and
equipment without relieving pressure first.
(10) Beware of highly pressurized oil
・
Hydraulic oil or reduction gear oil at high pressure can cause
serious skin and eye injuries.
Before cutting or opening a hydraulic pipe, always relieve the
pressure inside it.
・
Oil leakage may not be visible to the eye, so check with thick
paper or wood-shavings. Do not detect oil leakage by naked
hand or finger.
・
Wear protective goggles to protect your eyes.
・
If oil penetrates your skin, consult a doctor well experienced
immediately.
(11) Precautions on replacing seals etc.
・
After you remove an O-ring or other seal, wash the surfaces on
which it was fitted before you fit the replacement.
・
Before you fit an O-ring or other seal, check that it is
undamaged and cover it with a film of oil. If you find a
defective seal of any kind, do not use it because it could cause
oil leakage.
(12) Be careful when you open the radiator cap
・
When the radiator coolant is hot, it could spray out dangerously
when you take the radiator cap off, possibly causing burns.
・
If you have to take the radiator cap off, wait until the coolant
has had time to cool and slowly loosen the cap to allow pressure
to dissipate before you remove it.
