8 Operation
8.1 General Operating Instructions
All instructions for using the unit, whether in verbal or written form, are based on our own
experience and experimentation and can only be regarded as guidelines.
1. Prepare cap as per Point 7.
2. Turn the pressure valve (black knob on housing) to CLOSED.
3. Now increase pressure with the lever, staying within the permissible zone on the
pressure gauge (green zone).
4. If necessary, increase the pressure to the maximum, always staying within the
permissible zone on the pressure gauge (green zone).
5. Once the pressure remains steady, it can be released (valve opened).
6. Raise the piston and remove the cap.
The gauge will not be accurate while the pressure is being distributed through
the plastic. Full pressure can only be achieved by pumping on the lever
several times with appropriate pauses in between. Once the cap is fully
enclosed, the pressure remains steady.
The return spring on the piston takes it back automatically to its zero position.
It has a stroke of about 12 mm. As soon as it reaches this level, it is limited
automatically . No more pressure is possible.
The oil level should be monitored on the gauge when the piston is down. If
necessary, add hydraulic oil. A black vent screw is provided for this purpose.
To remove (oil filler nozzle). This is located behind the left-hand support at the
top of the housing. No damage can result from overfilling as the surplus oil
merely flows out into the nozzle.
Note: Use only SHELL TELLUS 32 hydraulic oil.
