the cap 16 from the motor and loosen the
cable by pulling out the plug-in seal 17.
8.2 Open the chuck and withdraw the rotary
instrument. Unscrew the end of the handpiece
21 (right-handed thread).

tool 22. To prevent the chuck becoming distorted,
an instrument shank or the pin supplied must
always be inserted into it. Hold the number 6223
23 wrench tightly and turn the chuck tool anti-
clockwise to unscrew the chuck completely -
the chuck has a right-handed thread!
