• Position the rotor carefully perpendicularly from above on the cone of
the motor shaft (see the illustration above, item 2).
CAUTION
If the rotor gets jammed or if it is lowered too quickly onto the fastening
stud, the thread of the stud may be damaged. In this case, it is no longer
possible to correctly secure the rotor in place.
• Insert the supplied hexagon key (part no. 930 050) into the hexagon
socket of the fastening stud of the motor shaft and hold it in place with
two fingers ("two-finger-principle", see the following picture). At the
same time, position the rotor wrench AF 17/19 (part no. 930 018)
against the flat sides of the rotor hub and turn the hub clockwise until it
is no longer possible to hold the hexagon key with two fingers.
