of screw M4 is 5 Nm and for M6 is 6 Nm. Hold the shaft with heavy duty pliers. Use glue for
screw fixation.
Previous press ring on motors 748.3.xxx and 749.3.xxx cannot be used because mating
surface for grounding brushes will be too small and also gap between press ring and brush
support will be too small and brush effectiveness and life time will not be sufficient.
