and
the

Make use of the hook wrench from the scope of delivery of the HF spindle.
Ü
Remove the tool.
Ü
Remove the collet type "D" and type "ER" from the clamping nut.
Ü
Remove the collet type "ER-MS" from the taper of the mount

Sample illustration:
Clamping nut type
Ü
Clamping nut type "ER-MS":
Ä
Push the collet into the taper of the mount.
Ü
Clamping nut type "D" and type "ER":
Ä
Push the collet into the clamping nut until it engages in the groove pro-
vided for this purpose.
The collet is inserted correctly when it is flush with the end face of the clamp-
ing nut. This is the only way in which to guarantee that the collet is also pulled
out when the clamping nut is loosened.
Ü
Insert the tool.
Ü
Make sure that the shank of the clamped tool does not press on the inner
stop of the tool mount once the clamping nut has been tightened.
Ü
To prevent the clamping nut from loosening, tighten it again after a short
period of operation and when the shaft is at a standstill.
