Believe it or not, this simple nut is crucial to your Nutrifaster’s operation. Gently hand-tightened into place, it holds the blade down to the motor within the center of the machine. Since the juicer is taken apart nightly for cleaning, with parts often being soaked overnight, this small part can be easily misplaced or lost. It’s recommended that management keep a spare nut stored away for safe keeping. That way, your business is guaranteed to be interruption-free, even if a nut goes missing in the night.
