3.Before fastening the blade assembly to the motor with screws and metal lockwashers provided, remove the rubber grommets (aka shipping supports) and motor screws. Keep the motor screws. These, too, will be used to attach the blade assembly to the motor. Repeat procedure for remaining blades (Fig. 2). Make sure screws are TIGHT! Use large, flat blade screwdriver for final tightening of motor screws to completely flatten the metal washers on the screws. Use of a cordless power screwdriver is not recommended, as they often strip the screw heads and do not tighten securely. Loose motor screws can contribute to unnecessary hum and wobble during operation.
