Maintenance
Item no. 10204051, Revision 02 30 ( 36 )
12.2.3 Every time the clamping device is changed
Ü
Clean the inner taper of the HF spindle shaft. The inner taper must be free
of chips and contamination.
Ü
Clean the tool taper.
Ü Apply a light greasy film to the taper of the collet after cleaning.
Ä Only use the collet grease from the service set.
