To protect your rights please read the following carefully

Bleeding air
It may be necessary to bleed air from pump case and outlet line to remove causes of vibration. An air bleed valve is recommended for this purpose.
Before first staring, fill pump case with clean operating oil via the filling port. In order to avoid air blockage when first starting, adjust the control valves so that the discharged oil from the pump is returned direct to the reservoir or the actuator moves in a free load.
Setting Discharge Pressure and Delivery 
At the time of shipment, the unit has been preset to maximum delivery and minimum discharge pressure.
Adjust the preset delivery and pressure to meet your system requirements.
Adjustment of Discharge Pressure 
Turning the adjustment screw clockwise, increases pressure.
