4.10.1 Fitting the drill chuck
Information
If the chuck can not be fixed with the draw bar, remove the draw bar from the spindle for the
installation of a drill chuck.
The drill chuck or the tool is secured in the spin-
dle against turning over by means of a form-lock-
ing connection (driver).
A frictionally engaged connection keeps and cen-
tres the drill chuck or the drill in the spindle.

Taper mandrel
Check or clean the conical seat in the spindle and on the taper mandrel of the tool or of the
drill chuck.
Press the taper mandrel into the spindle.
4.10.2 Unfitting the drill chuck
The taper mandrel is detached from the spindle using the draw bar. An drill drift must be used to
release the tapered connection, if drill chucks are used without internal thread for draw bars.
WARNING!
Only perform the following works if the drilling milling machine is disconnected from the
electrical
supply.
4.10.3 Installation of milling tools
CAUTION!
When milling, the seat cone must always be secured with the drawbar. A simple
connection with the taper bore of the work spindle without using the drawbar is not
permissible for milling. The cone connection is released by lateral pressure. Injuries may
be caused by flying parts.
The milling head is fitted with an M16 draw bar.
Remove the cap.
Clean the seat in the spindle / quill.
Clean the cone of your tool.
Insert the tool in the spindle / quill.
Screw the draw-in bar in the tool.
Tighten the tool with the draw-in rod and hold
the spindle on the counter bearing by means of
a wrench.
