IMPORTANT
Do not loosen the collet with the torque screwdriver with the sleeve () attached.
Doing so may damage the sleeve. Remove the sleeve from the torque screwdriver before loosening the collet.
IMPORTANT
The collet must be tightened at the specified tightening torque. Before tightening the collet with the torque screwdriver, be sure to attach a sleeve. Check the marking on the sleeve () and use a sleeve that matches the tightening torque value.
Failure to attach a sleeve will cause a torque in excess of the permitted amount to be applied, which may damage parts and materials.
