For a compactor to operate properly it requires a specific oil flow and sufficient oil pressure.

To begin, connect a flow meter into the circuit in place of the compactor. Measure the 'no-load' flow by pressing the compactor fire, which activates the control valve and simulates the compactor working. While still activating the 'compactor' fire, adjust the flow meter putting a load on the circuit. Adjust the flow meter pressure until it falls within the working pressure range:
