CAUTION!
Make sure that the clamped tool is firmly and correctly fitted.
4.12.1 Fitting the drill chuck
The drill chuck or the tool is secured in the drill spindle against turning over by means of a form-
locking connection.
A frictionally engaged connection keeps and centres the drill chuck or the drill in the drill spin-
dle.
Check and, if necessary, clean the conical seat in the drilling spindle and at the taper man-
drel of the tool or the drill chuck.
Press the taper mandrel into the drilling spindle.
4.12.2 Unfitting the drill chuck
Set the step switch to the neutral central position.
Switch off the master switch.
Turn the spindle by hand until the ejection openings are over each other.
Zero marker
Scale
Marking boring depth
Dial disc
Clamping lever
Turn the dial until the desired
drilling depth corresponds to
the marking on the scale.
Fasten the dial with the lever.
When reaching the set drill-
ing depth, the quill lever
jumps mechanically to the
"drilling depth marking", the
feed stops and the spindle
continues to turn.
The maximum drilling shutdown
is one rotation of the dial.
