[. . . ] Operating the quick-change chuck This chuck has been developed especially for use with percussion drills. The chuck has a release safety lock which prevents any unintentional release of the drilling tool even at high impact frequencies.

The torsion angle of the collar must be approximately 50° during the locking procedure. After this has been completed, the tool can be tensioned as usual. Turn the collar firmly in the "ZU" direction until a click is heard. The drill is only properly tensioned when the collar has been turned as far as possible and no more clicking is heard.
