Removing the rotor:

Dirt particles between the motor shaft and rotor prevent the rotor from
having a perfect seat and cause it to run unsteadily.
Clean the motor shaft (C) and the bore of the rotor (A) and then apply a thin coat
of grease to the motor shaft.
Place the rotor vertically onto the motor shaft. The driver of the motor shaft (D)
must be in the groove of the rotor (B). The groove alignment is marked on the
rotor.
Tighten the clamping nut of the rotor by turning it in the clockwise direction
using the key included in delivery.
Check the rotor to make sure it is seated firmly.
Loosen the clamping nut by turning it in the counterclockwise direction 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.
Place the hub (A) vertically onto the motor shaft (B). The driver (C) on the motor
shaft must be in the groove (D) of the hub.
Tighten the clamping nut of the hub by turning it in the clockwise direction using
the Allen key included in delivery.
Check the hub to make sure it has a firm fit.
Remove the rotor.
Loosen the clamping nut of the hub by turning it counterclockwise up to the lifting
pressure point. After overcoming the lifting pressure point, the hub is released
from the cone of the motor shaft.
Turn the clamping nut until the hub can be lifted up from the motor shaft.
Dirt particles between the hub and rotor prevent the rotor from having a
perfect seat and cause it to run unsteadily.
If necessary, clean the hub (A) on the motor shaft and the rotor hub before
inserting the rotor.
Lift up the rotor by the turning handle (E) of the lid, place it horizontally on the
hub (A) and press it down as far as it can go.
Hold firmly onto the rotor by the turning handle (E) of the lid and lift it off of the
hub (A).
