a) Ram advances
and retracts when handle is pumped ..
Removing Air From System.
1. Position the tool upside-down in a vice with the pump handle in
the open position.
2. Unscrew the fixed main handle from the body, then remove the
reservoir
end cap.
3. Pump the moving handle and press the release button in at the
same time, this will open hydraulic oil chambers and will allow the
air bubbles to rise out of the tool system into the oil reservoir. The
moving handle should be pumped for a minimum of 10 operations.
4. It is advised to leave tool upside down with end cap off for a further
10 to 15 minutes, this will allow any air bubbles that are trapped in
reservoir to rise and escape.
5. Top up hydraulic fluid if required , pump the moving handle
so the
ram advances but does not come under pressure. Now
press release trigger and close moving handle. This will
release oil back into the reservoir together with any trapped air bubbles.
6. After all air bubbles have been released, lightly squeeze the top
of the rubber reservoir so the oil is slightly over flowing and insert
the filler cap. Any excess oil should be wiped from tool before use.
Oil Refilling:
■
Check oil level periodically and top up if required.

OIL TYPE : TELLUS GRADE 15 ONLY.
