Hydraulic Pump does Not Raise the Pressure
Check that the pump is properly connected to the main supply.
Check that there is no sign of alarm in the control box.
Check for leaks in the circuit.
Check if right oil is used as per ambient temperature.
If the motor is running but there is no pressure, plug may be out of phase.
if the motor is running but the pressure does not raise above 200 bar, change the intensifier.
If the pump still does not raise the pressure, contact local Atlas Copco sales representative.
