1 Lower the carriage to bottom position.
2 Remove the cap plug from the inspection window (arrow).
3 Check the clearance between check screw (A) and safety nut (B). New load nuts have a
clearance of approx. 2 mm. If no clearance can be detected, the load nut is worn out and must
be replaced together with the safety nut.
4 At completion of wear check reinstall the cap plugs.

The correct setting of the clearance between wear check screw and safety nut is imperative for
proper functionality and safety of the lifting screw and load nut system.
If the clearance is not set properly when installing the new load nut, the wear and tear on the load
nut can no longer be reliably checked. In this case, the safe operation of the lift can no longer be
guaranteed.
