Hydraulic Settings
Check the working pressure by means of test equipment. The test equipment must comprise
a pressure gauge, a flow meter and a valve for adjustment of pressure.
The pressure relief valve is placed on the right side of the valve block.
1. Connect the test equipment, start the powerpack and move the lever to “ON”. Then close
the valve - the pressure gauge must show 150 bar.
Adjust the pressure relief valve by loosening the lock nut and turning the adjustment
screw in or out. “In” increases the pressure, and “out” decreases the pressure.
Retighten the lock nut after adjustment.
2. When the pressure relief valve has been adjusted correctly, the working pressure must
be set at 100 bar by means of the valve on the test equipment. At 100 bar, the oil flow
should be 20 (30) l. p.m.
On the powerpack with adjustable flow, the flow is regulated by adjusting the position of
the throttle cable.
If correct pressure/oil flow cannot be achieved by following the above
instructions, the powerpack must be re-adjusted. Then if the pressure/oil
flow is still incorrect, the pump is defect and must be replaced.
