ADJUSTMENTS
The grind can be set from very fine to very coarse. The amount may be adjusted for use in most commer-
cial coffee brewers. The following procedures should be used to make adjustments. A change in the burr adjust-
ment 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. Loosen the burr adjustment screw from its locked position.
5. 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 neces-
sary 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. 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 fine, to determine other settings, refer to the
previous section.)
3. Use the table on the next page to find approximate timer setting for the grind and amount of coffee desired.
