To clean the Burr, remove the Bean Container Lid and any beans. Trn the Burr clockwise until a "click" is heard, and pull the Burr out of the coffee bean chamber. Using a soft brush, clean away any coffee grounds from the Burr mounted at the base of this removable shaft. Within the motor housing, brush away any grounds from the fixed internal Burr. Lift and rotate the unit to lightly shake the remaining grounds out. DO NOT use water to wash these parts. DO NOT get the burrs wet. Reinsert the removable Burr by aligning with the fixed Burr within the motor housing and rotate counterclockwise to secure.
