grip surface of the shaft with the open-ended spanner (Art.No. 9188) and pull out the

3. Remove the chuck from the shaft
After thoroughly cleaning the chuck, slightly grease it on the outside with special
grease (Art.No. 51/1) before re-installation.
Tighten the chuck only slightly when re-installing! In normal operation (right-hand
rotation), the chuck tightens itself.
In order to preserve the chuck's accuracy and service life, a tool or the protective
pin provided from factory must always be clamped - even when the unit is not be-
ing operated.
Never clean the handpiece with compressed air!
The corresponding chuck tools can be found on the underside of the handpiece
rack.
