INTRODUCTION
This equipment will store up-to six pounds of whole bean coffee in each of two hoppers and grind it to a
preset grind and amount into an awaiting funnel and filter from most commercial drip coffee brewers. The
equipment is only for indoor use on a sturdy counter or shelf. Adequate space must be available above the
grinder to raise the lids when adding beans. Use only with whole bean coffee.
The grind is preset at the factory to drip specifications as set forth by the United States Department of
Commerce and adopted by the Coffee Brewing Center of the Pan American Coffee Bureau. Adjustments
may be made to alter both the amount and grind from the factory setting.
To reduce the risk of electric shock,
do not remove or open cover.
No user-serviceable parts inside.
Authorized service personnel only.
Disconnect power before se rvicing.

NOTE: If the power cord is damaged, it must be replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard.
The control board determines the amount of beans that will leave the hopper in a grind cycle. The timer
portion can be adjusted to dispense a different amount from each hopper and each batch size. The scale
is from 0.4 to 99.9 seconds. Refer to the Adjustments section for timer setting chart (page 8).

7. The following settings approximately correspond to the CBC recognized grinds. All are referenced from
the arrow position noted in #6.
ADJUSTMENTS
COMMUNICATING WITH COFFEE BREWER
When the grinder is used with its companion brewer, the name of the coffee and the size of the batch
ground is communicated to the brewer through the chip in the funnel handle as it is placed into the brewer.
Therefore, it is necessary to “tell” the grinder the names of the coffees that have been loaded into the
hoppers. The names are chosen from the Coffee Chart shown below. Contact the factory if custom names
that are not on the chart are required.

adjustment will also change the amount dispensed. Any adjustment of the burrs should be followed by an
adjustment of the timer.
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.

Three different batch settings are selectable for each hopper. Each batch is independently adjustable by
setting the length of time a slide gate opens to allow beans to drop into the grinding chamber. A second
time setting for each batch determines how long the grind motor continues to run after the slide gate
closes. This time is set long enough to insure that all the beans dropped into the grind chamber are
ground and dispensed.
