CHANGING A BROKEN SHEAR DISK

1. Unplug the power cord.

2. Empty the hopper of beans.

3. Remove the housing cover, held in place by two slotted

screws.

4. Take off the shear cap. Pull out the feed worm/grinding burr

assembly. These parts are slipped together and usually
come out in one piece.

5. Discard the broken shear disk.

6. Clean out the housing. Look for and remove any debris that
may have caused the shear disk to snap.

7. Reinsert the feed worm/grinding burr assembly on the motor

shaft.

8. Slide the shear drive through the center hole on the feed worm/grinding burr assembly. The end with the large
slot goes in rst. Align this slot with the tongue on the motor shaft as you push in the shear drive.

9. Rotate feed worm/grinding burr assembly to align the narrow slot with the narrow slot on the shear drive.

10. Insert a new shear disk into this slot and cover with the shear cap.

11. Clean off the inside surfaces of the housing cover. Replace the housing cover. If the housing cover doesn’t seat

properly, the shear drive is probably not aligning with the motor shaft (repeat step 8).

12. Plug in the power cord.

ADJUSTING THE GRIND TEXTURE

1. Empty the hopper of coffee beans.

2. Turn the selector knob clockwise as far as you can, to the ESPRESSO position.

3. Locate the two set screws, under the selector knob. Use an 1/8th inch Allen wench; loosen these screws one turn
to free the knob from the adjusting screw.

4. Run the grinder. Turn the adjusting screw slowly clockwise until you hear the grinding burrs making a clicking
noise. Back off on the adjusting screw 1/8th turn.

5. Tighten the set screws on the selector knob, your nest adjustment on the selector scale, ESPRESSO, is now set

and the rest of the dial positions will be accurate.

CLEANING

CAUTION – Unplug the grinder from the electrical power source.

Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These products pro-

mote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.

1. Clean the painted outside case of the grinder with a cloth dampened with a mild cleaning solution of dish washing

detergent and water. Dry thoroughly with a soft cloth.

2. Clean the inside of the hopper with a dry cloth.

3. Brush coffee grounds from the dispensing spout. Wipe off the surrounding area.

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. Run the grinder to empty the housing of any remaining coffee.

2. Pour in or two capfuls of grinder cleaner granules or tablets into the hopper (use manufacturer’s recommenda­tions).

3. Press a grind button, running the grinder until the cleaner empties from the spout.

4. Rell the grinder with whole bean coffee. Run two grind cycles to purge the grind housing of any residual cleaner.
