When unscrewing the screw in shaft, hold the motor shaft at the
other side if you are not able to unscrew the screw since the shaft
will rotate. Protect the shaft e.g. with a cotton cloth or soft metal or
some plastic. Then use e.g. heavy duty pliers, hold the shaft and
unscrew screw with screwdriver or tool. Be careful not to damage
the motor shaft. See picture A for additional information.
Avoid forces in axial or radial direction that are pulling the shaft
out of the motor.
