Pressure test of work hydraulic system
CLG835H
Pressure inspection and adjustment of main safety valve of control valve
1. Test method
Note:
Set the pressures of LS relief valve and the cut-off pressure of working pump to maximum before
adjusting the main safety valve of control valve, and then perform the following steps. In fact, the safety
valve basically does not work in the work hydraulic system, so it is not be adjusted in general.

Tools
1. Connect the pressure gauge
at pressure measuring point;
Pressure gauge
(range 40MPa\
5800psi);
2. Start the machine, operate
the lever to lift boom to
horizontal position (when the
diesel engine and hydraulic
oil is under normal operating
temperature, the diesel
engine will be in idle
running)
3. The level returns to the
neutral position;
