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. Remove the two screws from front control panel. Hang the panel under metal hooks at bottom of opening.

2. Enter the Setup Menu “TEST OUTPUTS” - “GRIND MOTOR” (See page 11). Turn grinder motor ON.

3. After all of the coffee in the grind chamber is used, slowly turn the adjusting

screw in a clockwise direction 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.)

4. Turn plastic grind indicator until screw slot lines up with “O” on the

indicator.

5. The following settings approximately correspond to the CBC recognized

grinds.

Turn the adjusting screw counterclockwise to the desired setting as noted below.

FINE GRIND: Rotate the adjusting screw 7 hash marks in a counterclockwise direction.

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

REGULAR (COARSE) GRIND: Rotate the adjusting screw 12 hash marks in a counterclockwise direction.
