INITIAL SET-UP
1. Open the top lid. Clear all foreign objects and shipping material from the hopper compartment and the entrance to
the grind chamber.
2. Plug in the grinder.
3. Fill the hopper compartments with whole bean coffee. (Capacity 6 pounds each). The grinder is now ready for
use.
CLEANING
The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all
surfaces on Bunn-O-Matic equipment. Care should be taken not to scratch the hopper or windows with any
abrasive material. Regular cleaning will keep your grinder looking new for years.
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 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 (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 and 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.)
6. Make a mark with a pen on the decal to note the position of the arrow on the grind
adjustment screw.
7. The following settings approximately correspond to the CBC recognized grinds.
All are referenced from the arrow position noted in #6.
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.
8. Hold the adjusting screw in its set position with a screwdriver while tightening the lock nut.
