2. Maintenance
2.1.1 Removing the chuck
Open the chuck 04 and remove the tool.
Push the chuck holder 18 onto the chuck
04. Fix the chuck 04. Turn the chuck 04
with the help of the chuck holder 18 until
the flanks of the spindle are visible at the
tip 01 and the flat spanner 17 can be
inserted. Insert the flat spanner 17 and hold
it tight. Turn the chuck holder 18 counter-
clockwise to loosen and unscrew the
chuck 04.
To reinstall, follow the above instructions
in reverse order. Screw in the chuck 04 in
the clockwise direction up to the end stop
and lightly tighten it.
2.1.2 Cleaning the chuck
Remove accumulated dirt if possible using
a suitable twist drill (max. 2 mm). Then
clean in an ultrasonic bath, repeating if
necessary. Dry the chuck well with com-
pressed air!
Also clean the cone before inserting. To
do this, dip one end of a Q-Tip in cleaning
agent (petroleum ether). Ensure that the
handpiece opening is held vertically down-
wards in order to prevent liquid getting
into the ball bearing. Clean the cone with
rotary movements. Subsequently, dry the
cone using the dry end of the Q-Tip.
Do not blow out with air! Lightly grease
the chuck all round on the cone and on
the thread side and insert in the shaft.
2.1 Cleaning or replacement of the chuck
Do not clean handpieces
with compressed air!
