8.3 Adjusting the operating pressure
The pressure control panel is set at the factory to a specific nominal operating pressure or aver-
age pressure (with the switching lever positioned in the middle). If necessary, this pressure can
be changed:
1. Position the switching lever (item 1) horizontally (middle position) and turn it anti-clockwise
to unscrew it out of the gear unit.
2. Loosen the grub screw (item 2) using an SW3 Allen key.
3. An SW6 Allen key (item 3) can now be used to adjust the working pressure by turning the
hexagon socket head screw (item 4) below the switching lever. The gear unit must remain in
the middle position!
– Turn clockwise: to increase the pressure level
– Turn anti-clockwise: to reduce the pressure level
In this case, gas must be removed so that the reduced pressure can be read off.
4. After adjusting the pressure level, re-tighten the threaded pin (item 2), screw the switching
lever back on, and position it to preselect the removal side.
8.4 Regular maintenance work and cleaning
For components in which the tests reveal wear or even malfunctions, repairs or component re-
placement must be carried out by competent specialist companies and persons.
