9.88”

1. Empty the hopper of coffee beans. Run the grinder for a short time to clear

grinding burrs of coffee.

2. Open the housing cover (10) to locate the adjustment screw (8) and lock nut (7). With a wrench, loosen the lock nut.

3. Turn the adjustment screw clockwise for a ner grind. Turn the screw counter clockwise for a more coarse grind. With the motor running, pour coffee beans into the hopper and turn the screw to make the adjustment. If you hear the grinding burrs starting to touch, immediately, back off 1/8th turn.

4. When the desired grind texture is satisfactory, hold the adjustment screw in place with the screwdriver and tighten the locknut.

5. Grind some coffee beans to conrm the adjustment.

6. Replace front cover on machine.

5. In the red window, the grind time on the button pressed will appear. Continue to hold and the time digits will start at 00 and increase. Release the button to set the new time. The table (left)can be used as a guide to estimate the amount of ground coffee you dispense with the chosen setting.

6. Wait for the motor to completely stop (10 seconds). To set and exit, press and

release any other grind button.
