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 position.
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. Make a mark with a pen on the decal to note the position of the arrow on the grind
adjustment screw.
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.
REGULAR (COARSE) GRIND: Rotate the adjusting screw 12 hash marks in a
counterclockwise direction.
9. Early Models only, hold the adjusting screw in its set position with a screwdriver while tightening the lock nut
to a snug position by hand. Slightly loosen the adjusting screw and retighten it to its prior position. The lock
nut should now be tight against the burr housing front cover.
Timer Adjustment
1. Unplug the grinder and remove the lower front inspection panel.
2. Determine the grind setting. (The factory setting is drip, to determine other settings, refer to the previous
section.)
