NOTICE
Replace the O-ring
Damaged O-rings are no longer able to fulfil their sealing function. As a result, the pressure re
-
quired at the jet valve can not be produced to its full extent. We therefore recommend that you
also replace the actuator O-ring when you replace the guide bushing.
► Coat the actuator O-ring with a little O-ring NBR in
-
side grease (special grease for actuator O-rings).
