Interval Inspection point
Re-tighten the threaded joint (tightening torque: 5 Nm).
Check whether the external bearings are still firmly screwed to the stator without gaps (tight‐
ening torque: 6 Nm).
Check that there are no thick layers of dust on the motor housing and external bearings.
Heavy layers of dust interfere with heat radiation.
If friction is noticeable when the rotor is running, immediately stop the motor. The alignment
of the load guide and the rotor must be checked - see operating instructions for the motor.
