Pressure Measurement
There are three points to measure the pressure; at the relief
valve, at the arm tip attachment hose and by Dr.ZX.
Measurement at the relief valve:
1. Install a pressure gauge to the pressure gauge connec-
tion port shown below.
2. Close the stop valve located at the arm tip. Increase the
hydraulic oil pressure in the hydraulic line by operating
the attachment pedal. Refer to the separate table de-
scribed in the “ATTACHMENT” group for the set-pressure
value.
Measurement at the arm tip attachment hose:
1. Disconnect the attachment connection hose and con-
nect a pressure gauge.
2. Refer to the separate table described in the “ATTACH-
MENT” group for the set-pressure value.
Measurement by Dr.ZX:
(Consult with your nearest Hitachi dealer.)
Set the pressure value equivalent to the higher set-pressure
value shown in the separate table described in the “ATTACH-
MENT” group by 1 to 1.5 MPa (10 to 15 kgf/cm
2
).
