INITIAL SET-UP/ADJUSTMENTS
The grind can be set from fine to very coarse. The grind may be adjusted for use in most commercial coffee
brewers. The following procedures should be used to make adjustments.
NOTE - A change in the burr adjustment will also change the amount dispensed. Any adjustment to the burrs
should be followed by an adjustment of the timer dials.
Burr Adjustment
1. Unplug the grinder and empty all beans from the hopper(s).
2. Plug-in the grinder, place funnel with filter into the funnel rails. Mo-
mentarily press the Off/On/Start switch to the "START" (lower) position
(with desired hopper selected) and release, run a few grind cycles until
all of the coffee in the grind chamber is dispensed.
3. Remove the funnel with filter and carefully tip the grinder over on it's
back.
4. Place the Off/On/Start switch in the "START" (lower) position and, using the grind adjustment key provided,
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 the sound).
5. Make a mark with a pen on the decal to note the position of the arrow on the grind adjustment screw.
6. The following settings approximately correspond to the CBC recognized grinds. All are referenced from the
arrow position marked in step #5.
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 10 hash marks in a counterclockwise direction.
NOTE: Exact adjustment will vary according to bean roast or added flavoring.
Timer Adjustment
1. Unplug the grinder and remove the rear cover.
2. Set each timer to 5 seconds for each ounce of ground coffee de-
sired.
3. Verify the setting by weighing a few samples.
Use this 5 second per ounce figure as an APPROXIMATE guide only.
