● 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.

If the sleeve has been broken the head has to be repaired by Siemens because the ball bearings of the z-axis
may have been damaged, too. If the shaft seizes due to the ball bearings of the z-axis or the z-clamping the
head must always be repaired by a Siemens.
