the toothed rod (2), intermediate piece (12) and the pressure
strip (18), into the housing (1) and combine them by mounting
the drivers (7).
3 Locate the springs (43) into the provided undercuts of the
bushing (7).
4 Insert the centering bushing (19) and mount the device 1 with
screw 1 (3 pieces) onto the housing.
5 Locate the O-ring (26) into the undercut of the piston rod (5) and
place the piston (4) carefully with the mounted seals (20) into the
device’s bore, until it contacts the pressure springs (43).
