Installation:

Clean the motor shaft (A) and the bore of the rotor and then apply a
thin coat of grease to the motor shaft. Dirt particles between the
motor shaft and rotor prevent the rotor from having a perfect seat and
cause it to run unsteadily.

Place the rotor vertically onto the motor shaft. The motor shaft dog
(B) has to fit in the rotor slot (C). The alignment of the groove is
labelled on the rotor (D).

Tighten the clamping nut of the rotor with the Allen wrench (included
in delivery) by turning clockwise.


Check the rotor to make sure it is seated firmly.

Allen wrench (included in delivery) and turn up to the lifting pressure
point. After overcoming the lifting pressure point, the rotor is released
from the cone of the motor shaft. Turn the clamping nut until the rotor
can be lifted up from the motor shaft.
