Grind is too coarse/Grind range is not acceptable
The cutting burrs may need to be adjusted or replaced.
Adjusting/calibrating the burrs:
1. Empty the bean hopper, and then run the mill a few seconds to clear any remaining beans from the machine.
2. Turn the grind control dial to level 8 for maximum grind fineness or 1 for maximum grind coarseness.
3. Using a 5/32 inch Allen wrench, remove the screw located in the front of the grind control dial by turning it counter-clockwise. Hold the grind control dial so that it does not rotate as the screw is removed.
4. Turn on the mill.
5. Rotate the grind control gear clockwise 1 ―"click" at a time until you hear the burrs touching one another – when they touch, the burrs will make a distinct rubbing or grating sound.
6. When the burrs are touching, turn the grind control gear counter-clockwise 1 "click". The grating sound will stop. Turn off the mill.
7. The mill is now calibrated.
8. Re-attach the grind control dial making certain the dial indicator points to grind level 8 for fineness or 1 for coarseness.

Replacing the burrs
- Remove the faceplate and burr-shaft assemblies. (See Cleaning the Cutting Burrs, steps 1 – 3.)
- With a Phillips screwdriver, remove the burr from the burr-shaft assembly by turning the two burr-mounting screws counter-clockwise until free.
- Remove the burr from the motor housing by turning the two burr-mounting screws counter-clockwise until free.
- Attach the replacement burrs to the burr-shaft assembly and motor housing using the burr-mounting screws. Make certain the cutting surfaces of the burrs face outward, and the burr-mounting screws are tight.
- Insert the burr-shaft assembly into the motor housing and attach the faceplate assembly. (See Cleaning the Cutting Burrs, steps 5 – 10.)
Note: The Use and Care Guide suggest replacing the cutting burrs when they become worn, usually every 600 – 800 pounds of ground coffee.
Burrs cannot be removed
Coffee residue can build up around the burrs causing them to be difficult to remove.
- Instruct the consumer to press down on the burr-plate in short clockwise and counterclockwise motions. The faceplate should then pop out.
- It also may be helpful if the coffee residue between the burr and the inside of the housing is loosened with a toothpick and brushed out if burr is difficult to move.
Cleaning the cutting burrs
a. Make sure the mill is switched off and unplugged. Remove the coffee bin and bean hopper from the mill.
b. Using a flat-head screwdriver, turn the two faceplate screws counter-clockwise until the faceplate assembly is free. (The faceplate screws have retaining clips that prevent them from being removed from the faceplate assembly.)
c. Carefully slide the faceplate assembly away from the motor housing. A separate burr-shaft assembly on the inside of the motor housing will usually slide out with the face plate assembly. Place a hand under the burr-shaft assembly to prevent it from falling as the faceplate assembly is removed. If the burr-shaft assembly does not slide out with the face-plate assembly, grasp the center shaft of the burr-shaft assembly and remove it from the housing.
d. Using the burr-cleaning brush, clean the burr mounted on the burr-shaft assembly and the burr mounted within the motor housing.
Note: Never wash the burrs or burr-shaft assembly in water. Keep them dry at all times.
e. After cleaning, tilt the grinder backward so the front of the motor housing faces upward.
f. With the corkscrew-shaped auger shaft facing into the motor housing, insert the burr-shaft assembly into the grinder. Keep the burr-shaft assembly level, so the tip of the auger shaft will line up with the small socket in the motor housing.
g. Once the burr-shaft assembly is in the motor housing, rotate the assembly until it falls into place. When correctly positioned, the burr-shaft assembly cannot be rotated.
h. Place the faceplate assembly onto the motor housing. Make sure the numbers on the grind level ring are positioned across the top of the assembly. Using your fingers, tighten the faceplate screws by turning them clockwise. Alternate tightening the screws, keeping them even – do not completely tighten one screw before tightening the other.
i. After the faceplate screws have been finger-tightened, use a flat-head screwdriver to tighten them until snug.
j. Place the grinder upright. It is now ready for use.
