5.2) Purging air bubbles from the internal hydraulic circuit
The operations of connecting and disconnecting the flexible hose and hydraulic heads could
7
cause air bubbles to form in the hydraulic circuit over time, adversely affecting the performance
6
of the pump.
To purge air bubbles from the circuit proceed as follows:
1
– Connect the hose and the hydraulic head to the pump.
– Place the hydraulic head onto a flat surface, keeping it in a vertical position.
8
– Leave the pump in inclined position (see Fig. 8) at a height approximately 1,5 m (4.9 ft)
higher than the head.
– Operate push button until the pressure switch intervenes.
– Completely discharge the oil pressure pushing the release button.
– Repeat at least 3-4 times to ensure all bubbles collect in the upper part of the reservoir.
– Check the oil level, topping up if necessary (see § 5.1).
