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.

grease. Lubricate shaft core with shaft grease only lightly
(1 kg can, order no. 904 832). Replace worn shaft core
(see SUHNER catalogue). Keep hose coupling in clean
- lightly greased condition. Replace worn couplings (see
SUHNER catalogue).
