OCCASIONALLY
In the event of leaking seals, oil can
be topped up via the filler plug on
the side of the pump. Oil should be
level with the bottom of the hole. If
necessary top up with CLARKE
hydraulic oil, Part No. 3050830.
This
task is carried out with the ram fully
retracted.
Further repairs should be
carried out by your Clarke dealer.
If any rust is apparent it must be
removed and the paint restored.
In the event of an airlock, air bubbles can be purged from the ram as follows;
1. Depress the release valve pedal.
2. Pump the actuating pedal several full strokes to eliminate any air bubbles.
Top up the hydraulic oil to the lower level of the filler plug with CLARKE
hydraulic oil, Part No. 3050830.
