Whenever a damaged hose or loosened bolt is found, abort working and ask us or our sales
service agency for a repair.
• Replacement of high pressure hose requires experienced skill. In addition, the tightening
torque is decided by the hose types and size.
Customers are prohibited to repair.

• Hose sleeve damage or leak.
• Scratch or truncation of the coat, or exposure of reinforcing layer of a wire.

HIGH PRESSURE OIL CAUTIONS
Failure to check to make sure the pneumatic circuit pressure
is relieved before inspection or replacement of a high
pressure piping or hose may result in accidents.
Strictly observe the following.
• Do not start any inspection or replacement before the
pressure dissipates.
• Put on safety goggles and leather gloves.
• When a piping or hose leak exists, the piping/hose itself or
its vicinity or the ground is wet. Crack or inflation of piping or
hose is likely. Contact us or our sales service agency for
repair.
• High pressure oil leaking through a small hole may puncture
the skin or destroy eyesight upon contact.
If this happens, wash away with flowing water and see the
doctor as soon as possible.
CAUTIONS WHEN TEMPERATURE IS HIGH
Parts such as the engine, oil in various parts, exhaust system
manifold and muffler are at high temperature immediately
after stopping of the engine.
Attempt to remove the cap or execute maintenance such as
oil draining, water draining or filter replacement in this
condition may result in burns.
Wait until the temperature lowers, then execute the
inspection/maintenance following the procedure described in
this manual.
