nstructions
During operation avoid sharp bendings of the flex-
ible shaft. Excessively small bend radius will result
in premature wear. Strong whipping movements
and convulsions of the flexible shaft are signs of overload-
ing. As countermeasures use smaller tool or increase ro-
tational speed. However, this only in stict observation of
the instructions on the maximum allowed circumferential
speed of the respective tool.
