Setting back-pressure (pressure holding)
The back-pressure is adjusted to 0,1 MPa (1 bar) + 20%, on the manufacturing side.
If a different pressure is required, the adjustment can be done as follows:
1.
Remove the sealing plug (Pos. 10) at the pressure holding operation button (Pos. 2)
either manually or with a small screwdriver.
2.
Disengage the screw (Pos. 11) and remove the operation button.
3.
Pull out the adjustment button (item 12) slightly and set the desired counter pressure
by turning (right stop approx. 0,1 MPa (1 bar), left stop approx. 0,05 MPa (0,5 bar).
4.
Then fixate the adjustment button by pushing it back in, replace the operation button,
tighten the screw and insert the sealing plug.
