Adjusting the operating pressure

The pressure control panel is set at the factory to a specific nominal operating pressure or average 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.
