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.
