COFFEE GRINDING
1. Visually inspect the selected hopper for an ample supply of whole bean coffee.
2. Place a paper filter into the brew funnel. The filter must not be folded-over or tilted to one side.
3. Insert the funnel into the funnel rails and push until it stops.
4. Choose the batch size and side of grinder to use.
5. Press the GRIND button. The grinding action will stop automatically after the preset amount of ground coffee
is dispensed into the funnel.
ADJUSTMENTS
The grind can be set from very fine to very coarse. The amount may be adjusted for use in most commercial
coffee brewers. The following procedures should be used to make adjustments. A change in the burr adjustment
will also change the amount dispensed. Any adjustment of the burrs should be followed by an adjustment of the
timer.
Burr Adjustment
1. Unplug the grinder and empty all beans from the hoppers.
2. Plug in the grinder, press and release the GRIND button (with either hopper selected). Run a few grind cycles
until all of the coffee in the grind chamber is used.
3. Remove the upper front inspection panel.
4. Loosen the locknut by one turn.
5. Press the GRIND button and slowly turn the adjusting screw in a clockwise di-
rection until a metallic whine is heard due to the rubbing of the grinding burrs.
(It may be necessary to start more than one grind cycle to obtain this sound.)
6. Turn plastic grind indicator until screw slot lines up with “O” on the indicator.
7. The following settings approximately correspond to the CBC recognized grinds.
All are referenced from the arrow position noted in #6.

DRIP GRIND: Rotate the adjusting screw 8 hash marks in a counterclockwise direction.
