Hydraulic system is always under internal pressure.
When inspecting or replacing piping or hoses, always
check that the pressure in the hydraulic circuit has
been released. If the circuit is still under pressure, it
will lead to serious injury, so always do as follow.
Never attempt any inspection or replacing operation
if hydraulic system is under pressure.
If there is any leakage from piping or hoses, the
surrounding area is wet, so check for cracks or
swelling in the hoses. When carrying out inspection,
wear goggles and leather gloves.
High pressure oil leaking from small holes may
penetrate your skin or cause blindness if it contacts
your eyes. If you are hit by a jet or high pressure oil
and suffer injury to your skin or eyes, wash the place
with clean water, and consult a doctor immediately
for medical attention.
