• Repeat these steps two or three times to remove all air bubbles out of the
press. Then conduct a pressure test.
(See the following Chapter on the pressure test)
If you do not reach the required pressure of 25 tonnes during the pressure test,
there must be air in the press still. In that case, proceed as follows:
• Remove the die tool.
Fig. 16:
• Pull the cylinder plate (G) upwards and off.
• Use the supplied hex key to loosen the ventilation screw (ES).
• Close the shut-off valve (H).
• Using the lever (B), pump very slowly until oil appears in the ventilation
opening (ES).
It may be necessary to wait until no more air bubbles rise upwards.
• Then tighten the screw (ES) again and insert the pressing plate (G) again.

• Close the shut-off valve (H) by turning in a clockwise direction.
• Then pump by moving the hand levers forwards and backwards until a

There is an overpressure relief valve inside the press. This is set to 25-t. The
overpressure relief valve may be set only in the factory.
If the hand lever (B) is actuated when the set pressure of 25 t is actuated again,
the safety valve prevents damage to the press.

The press is for designed for many yearsof operation and requires only very little
servicing . From time to time, you should check if the threaded spindle on the press
can move easily.
• Clean and oil the press as required.
No further maintenance is needed.
