Protecting the wrist joints
The sealings between the moving parts on the wrist must not be exposed to direct
high-pressure water. We recommend that the gripper include a shield that prevents
direct water flush on the sealing surfaces of the wrist. The sealings are pointed
out in the illustration below.

the wrist flange and the tool and the screw holes on the wrist flange must be
protected.
