Pressure test of work hydraulic system
CLG835H
Inspection and adjustment for pressure of working hydraulic pressure system
1. Test method
Note:
if the pressure measured at the end of oil cylinder may be about 1-2MPa\145-290psi more than
that of pump opening, the variable system pressure is subjected to the pressure of pump opening.

Operation instruction
Tools
1. Connect the pressure gauge
at pressure measuring point
6 (as shown in figure);
Pressure gauge
(range 6MPa/
870psi);
2. Start the machine, idling
without action; The value of
pressure gauge in pressure
measuring point 6 (as
shown in figure) is
2.6±0.1MPa/ 377±14.5psi;
3. In event of reaching the
value, start the machine and
operate the pilot valve to tilt
back the bucket with very
slow speed till suppression;
pay attention to the value on
the pressure gauge of pres-
sure measuring point 6;
4. During step 3, when bucket
is suppressed, the value on
pressure gauge of pressure
measuring point 6 shall be
19±0.3MPa\2755±43.5psi
constantly.
Pressure gauge
(range 40 MPa/
5800psi).
