Notice!
Relevant safety rules of high-pressure oil
The internal part of the hydraulic system always has pressure; when
checking or replacing pipes or hoses, the pressure in the hydraulic oil pipe
must be checked whether it has been released or not. If oil pipe still has the
pressure, serious injury or damage can be caused, so the following rules
need to be obeyed:
– When the hydraulic system has the pressure, before releasing the
pressure, do not carry out check or replace.
– If the surrounding area of the pipes or the hoses is wet, the pipes or the
hoses should be checked for break, and the hoses for inflation.
– When checking, goggles and leather gloves should be worn.
– The high-pressure oil which leaks from small orifices can penetrate skin
and may cause blindness if contact eyes directly. If skin or eyes
contacted with the high-pressure oil were injured, skin or eyes should be
flushed by clean water and go to hospital for treatment immediately.
