extended use, it may be necessary to adjust the burrs.

beans in the burrs. Remove the front access panel.

flat-head screw driver to turn the adjustment screw one full turn

clockwise until the burr teeth just begin to click. Then, turn the

adjustment screw counterclockwise 1/8 turn, or until the clicking

stops.

Return the adjustment head to its original position. Refill the

hopper and run several tests to be sure the grind is satisfactory.
