Design and Function
Pump (1) builds up oil pressure which reaches rams (11) through hoses (8).
Overpressure is avoided by a relief valve. Gauge (7) is used for setting the oil pressure required for the
spec ific screwed joint. Hand wheel (6) is turned to let off pressure afterwards. Safety hose couplings (10) and
(12) are used in combination with H.P. hoses (8) and distributor (9). If less than four rams are operated, the
unused hoses must be closed with half-coupling (10) and their locking nipples.
Filling and Bleeding
The normal working position of pump (1) is horizontal, but the vertical position - hose connection down
- is also permissible.
Use only one of the following hydraulic oils:
BP Energol Hydraulici 50 Mobil Hydraulic oil
BV E 100 Heavy- duty oil Shell AB 11 oil
Esso Zerice 36 Viscobil Sera I oil
Gasolin Special AS Viscobil oli CL 40 oil
Any other oils are liable to affect sealing materials. Definitely unsuitable are brake fluids, dashpot oils, gas,
oil, kerosene or gasoline/petrol.
Job:
Fill pump (1) through hole (3) with min. 1,5 litres of oil. Connect pump (1), support for gauge (7), distributor (9)
to hoses.
Operate pump lever (4) until hoses are bled.
Unscrew safety half-coupling (12) from tool. Fill tool with oil and refit half-coupling. Connect hoses.
All parts of the hydraulic device must be in perfect shape. This applies in particular to the hoses, which
must never be sharply bent or pulled.
