Adjustments, Burr Adjustment, Timer Adjustment

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, momentarily press the off/on/start switch to the “START” (lower) position (with either hopper selected) and release, run a few grind cycles until all of the coffee in the grind chamber is used-up.

3.Remove the upper front inspection panel.

4.Early Models only, loosen the burr adjustment screw from its locked posi- tion.

5.Early Models only, hand loosen the adjustment locking nut around the screw approximately one turn.

6.Press the off/on/start switch to the “START” (lower) position and release, 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.)

7.Early Models only, make a mark with a pen on the decal to note the position of the arrow on the grind adjustment screw.

Late Models, turn plastic grind indicator until screw slots line up with “O” on the indicator.

8.The following settings approximately correspond to the CBC recognized grinds. All are referenced from the arrow position noted in #7.

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.
