PLEASE NOTE
If the spring plate of the sleeve mount is broken, the entire mount must be replaced.
● Fix the mount for the sleeve removal to the lower end of the sleeve.
● Unscrew the star.
● Lift the damaged spring steel sheet away from the star and fit the new plate. The alignment is determined
by the centering pin. The three beads in the spring steel sheet should point downwards.
● Remove any residues of glue from the thread.
● Apply a little LOCTITE 241 adhesive to the thread.
● Firmly bolt the star to the new spring steel sheet.
WARNING
Do not move the z axis unless the clamping device has been deactivated, since this could damage the
sleeve clamping device.
● Check the zero point correction of the d axis.

● Deactivate the z axis clamping device and push the sleeve up so that the bearing housing covers the end
face of the end position BERO (item 6, Fig. 8.3.1 page 8 - 12).
● Turn the bearing housing (item 11, Fig. 8.3.2 page 8 - 15) counterclockwise - viewed from above - towards
the mount (item 8, Fig. 8.3.1 page 8 - 12). This will activate the BERO.
● Now turn the bearing housing and the anti-rotation lock (items 10 and 11, Fig. 8.3.2 page 8 - 15) clockwise
towards the mount. The BERO should not be deactivated.
● If this is not the case, loosen the two M2 screws on the anti-rotation lock and push the lock towards the
mount. Tighten the two screws.
PLEASE NOTE
The gap between the anti-rotation lock and the mount should be between 0.5 mm and 1 mm.
● Check that the BERO switches correctly by moving the sleeve up and down several times. To do this,
loosen the z axis clamping device.
● Deactivate the clamping device and move the sleeve up and down. The end position BERO (item 6, Fig.
8.3.1 page 8 - 12) must switch.
