GRINDING DISC REPLACEMENT AND CALIBRATION

Be sure to use a large, industrial flat blade screwdriver to avoid stripping the screws.

Removing the Old Discs:

1. Unplug the grinder.
2. Remove the plastic hopper and stationary plate.
a. 804 model grinders – loosen the rear left hopper lock
screw. Hold the plastic hopper and twist it counter-
clockwise 30°, and lift. Remove the screw holding the
stationary plate down, and remove the plate.
b. 805 model grinders – unlock the hopper safety lock before
twisting it up and off. Remove the top cover. Remove the
discharge tube and stationary plate to reveal the lower
grinding disc.
c. All other models – remove the screws holding the top plate
on the housing, and lift the cover/hopper assembly.
Remove the screws holding down the stationary plate, and
remove the plate by placing your thumb in the center hold
and pulling it up.If the disc does not move as you are
pulling up with your thumb, tap the edge of the disc with
the plastic handle of the screwdriver.
3. Remove all the screws holding on the discs. To keep the
rotating disc from turning, insert the plastic handle of a tool
inside the exit hole in the grinding chamber. Be careful not to damage the heads of the
screws, as it would make it difficult to remove them. (Note: The 805 uses magnets in place of
screws to hold the grinding disc in place. Place the tip of your screwdriver in the groove on the
inner edge of the discs to "pop" off).
4. Clean the areas marked "X" with steel wool or a single edge razor blade, and make them
perfectly clean. If the mating surfaces are not clean, you cannot get a fine grind.

Installing and Calibrating the New Discs:

1. Make sure that the discs are clean with no coffee or dirt particles on the underside.
2. Check the back of the discs – newer-style machined discs are marked "top" and "bottom"
for positioning.
3. If you are installing resharpened discs and you were provided spacers, use them. If you
have 1 spacer, install it under the top disc. If you have 2 washers, install a spacer under
each disc.
4. Install the discs, making sure the screws are tight.
5. Make sure the top edge of the grinding chamber and the underside of the stationary disc
are perfectly clean.
6. Adjust the grind setting to #9.
7. Align the screw holes of the stationary disc with the grinding chamber, and insert the
screws tightly.
8. Replace the cover with the plastic hopper. Now you can plug in the grinder.
