ADJUSTING THE GRINDING BURRS
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 finer grind. Turn the screw coun-
ter 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 confirm the adjustment.
6. Replace front cover on machine.
*This adjustment may change the amount of ground coffee dispensed.
CHANGING A BROKEN SHEAR DISK
1. Unplug the power cord.
2. Empty the hopper of beans.
3. Take out the thumb screws (9) to remove the housing cover (10).
4. Pull out the grinding burr/feed worm assembly (3). The mating alf of the grinding burr set remains within the housing.
5. Separate the shear cap (6) and shear drive (4). The snapped shear disk (5) should fall from the shear drive.
6. Inspect and brush out the housing (1).. Especially look for anything that could have broken the shear disk.
7. Insert the feed worm and grinding burr onto the motor shaft.
8. Push the shear drive through the burr/feed worm assembly and align it with the tongue on the motor shaft.
9. Rotate the burr/feed worm assembly to align the slot with narrow slot on shear drive.
10. Insert a new shear disk into the slot. Cover with the shear cap.
11. Replace the grind cap and two thumb screws.
