ADJUSTING THE GRINDS*
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.
*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 half 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.
Cleaning the Coffee Grinder
CAUTION – Unplug the grinder from the electrical power source.
Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These products
promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.
1. Brush coffee grounds from the dispensing spout. Wipe off the surrounding area.
2. Make a mild cleaning solution. Mix dish washing liquid in warm water.
3. Avoid spilling liquid into the grind housing. Wipe exterior surfaces with a cloth moistened with cleaning solution.
5. Wipe exterior surfaces with a water soaked cloth to rinse off all traces of the cleaning solution.
6. Dry exterior surfaces with a clean soft cloth. Polish exterior surfaces with stainless steel polish.
8. Return power to the grinder.
A tablet style grinder cleaner may be used to clean the inside of the grind housing, the burrs and chute. The product
will eliminate taste and odor left in the grinder from grinding avored coffee. The regular use of grind cleaner reduces
the need to disassemble the grinder to clean it.
1. Empty coffee beans from the hopper. Plug power cord into the electrical outlet.
2. Place a container under the grind spout and run the grinder to empty the housing of all coffee.
3. Pour in grinder cleaner granules or tablets into the hopper (use manufacturer’s recommendations).
4. Press a grind button, running the grinder until the cleaner empties from the spout.
5. Rell the grinder with whole bean coffee and run two grind cycles to purge the grind housing of residual cleaner.
