Loosen the clamping screw for fixing the BERO.
●
Replace the BERO.

Position the BERO so that its end face is flush with the housing.
●
Fix the BERO in place.
●
Check that the BERO switches correctly.
8.3.7 Adjust Anti-Rotation Lock on Bearing Housing
See item 10 in Fig. 8.3.2 page 8 - 15
Two horizontal slots have been milled into the anti-rotation lock for adjustment purposes.
Adjust the anti-rotation lock
●
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.

WARNING
∆
!
This servicing work may only be carried out by authorized and trained personnel.
●
Remove the clip (item 7, Fig. 8.3.2 page 8 - 15) from the vacuum connector at the top of the sleeve.
●
Pull the vacuum hose off the vacuum connector (item 8).
●
Fix the sleeve removal mount to the lower end of the sleeve.
●
Firmly hold the sleeve and the sleeve removal mount and then loosen the hexagonal nut (item 9) at the top
of the sleeve using the size 13 open-ended spanner.
●
Using a 2 mm hexagon socket head spanner, loosen the fixing screw (item 5) on the clamping part
(item 6).
WARNING
∆
!
Before you remove the sleeve, loosen the z axis clamping device by pressing the red push-button on the
solenoid valve for the z axis clamping device (see items 4 and A, Fig. 8.2.1 page 8 - 4).
●
Pull the sleeve down and out.
To reassemble the sleeve
●
Insert the new sleeve from the bottom.
●
Check that you have released the z axis clamping device. The sleeve must move easily. If it does not
move easily, the linear ball bearing may be defective (item 1, Fig. 8.3.2 page 8 - 15). If this is the case,
return the IC head to Siemens for repair.
●
Tighten the hexagonal nut (item 9, Fig. 8.3.2 page 8 - 15) at the top of the sleeve.
