Un-secure six M8 bolts and unscrew them (note that M8 screw located below power
cables has a lower head). To accomplish removal of the screws, support the motor
assembly.

Take out motor assembly carefully. Note that centrifugal ventilator on the back side
of the motor has bigger diameter than rotor rink. It is not possible to get motor out
straight, as opening is not wide enough. It is necessary to rotate motor about 30
degrees to one side in order to get it out. Be careful not to damage spinner, or plastic
covers below spinner.
