When opening the quick chuck with too much force, the chuck can get
over wound. In this case, the chuck can not be closed normally and a
latching noise is heard when turning the chuck in the closing-direction.
Remedies: After moving in the closing-direction, overwind the chuck
again in the release-direction until a click is heard.
The quick chuck can then be used in a normal way again.
If you experience a malfunction which can not be resolved, please contact your
authorized Heidolph distributor immediately.
