NOTE: This electrical service
consists of 2 current carrying

OPERATING CONTROLS
Grind Selector
Allows the user to vary the grind for each coffee. Each setting will provide precisely the same grind every
time it is selected.
Off/On/Start Switch
STOP/OFF - (upper position) Switching to this position stops the operation of the grinder.
ON - (center, resting position) The switch will return to this position after a grind cycle has begun and
will remain in this position after grinding has ceased.
START - (lower, momentary position) Pressing the switch initiates grinding only when a bag or other
container is in place behind the chute or if using the optional trifecta kit; the brew cup is in place.
Bag/Brew Cup Switch
Prevents the grinder from operating unless the back of a bag is in place behind the dispense chute or the
optional trifecta brew cup is not in place. Do not attempt to bypass this safety device.
Cleaning Lever
Allows the operator to clean out any coffee residue left from the previous grind.
Bag Clamp
Allows the operator to clamp the coffee bag in place and not have to hold it during the grind operation.

BURR ADJUSTMENT
1. Place an empty bag in place on the screen, with the back of the bag behind the dispense chute. If you
have the optional trifecta kit, place the brew cup into holder.
2. Start the grinder to clear the grind chamber. Leave grinder “ON”.
3. Turn the Grind Selector knob to the “0” (or “TURKISH” if using the icon based decal) position.
4. Using a small flat blade screwdriver, loosen the two set screws on the left side of the grind
selector knob.
5. Hold the knob in the “0” (or “TURKISH” if using the icon based decal) position with one hand.
6. Using a large flat blade screwdriver, slowly turn the adjusting screw in the center of the grind selector
knob to the right (clockwise) until a metallic whine can be heard due to the rubbing of the grinding burrs.
7. While holding the knob in the “0” (or “TURKISH” if using the icon based decal) position, back off the
screw to the left (counterclockwise) just until the metallic whine ceases.
8. Turn-off the grinder.
9. Push the knob against the dial plate and tighten both set screws on the left side of the grind
selector knob.
10. Turn the grinder on and listen again for the metallic whine with the grind selector knob in the “0” (or
“TURKISH” if using the icon based decal) position. If the metallic whine is heard, repeat steps 7 through
10 until the sound ceases.
11. If no metallic whine is heard, the grinding burrs are adjusted properly. On trifecta models, you should
hear a slight chirp of the burrs contacting if you rotate the knob fully clockwise past the “1” position.
COFFEE GRINDING
1. Load the desired weight or volume of beans into the bean hopper.
2. Turn the selector knob to align the arrow with the desired grind size.
3. Press down on the lever to open the bag clamp bracket.
4. Locate bag between the rear of the chute and the clamp bracket, then release the lever.
(The grinder will not operate unless the bag sensor is activated)
5. Press the start switch.
6. Flip the cleaning lever a few times as dispensing slows.
7. Remove the bag or brew cup when ground coffee is no longer dispensed from the chute. The grinder
will stop automatically as the bag or brew cup is removed.
NOTE - The start switch will have to be pressed again to continue the cycle if the bag or brew cup is removed
while grinding.

WEEKLY CLEANING
Clean all exterior surfaces using a damp cloth rinsed in any mild, nonabrasive, liquid detergent. Care should
be taken not to scratch the grinder with any abrasive material.
6 MONTH CLEANING
1. Empty all beans from hopper(s). Plug in the grinder, place an empty bag behind the dispense chute or
trifecta brew cup. Press and release the “START” switch. Run a few cycles until all coffee in the grind
chamber is dispensed and disconnect the grinder from the power source. Remove the bag or brew cup.
WARNING - Prior to cleaning the grind chamber, unplug the grinder.
2. Remove the two screws and remove the dial plate and selector knob assembly.
3. Slide the burr auger rotor/spring assembly off the motor shaft and disassemble for cleaning.
4. Remove the two screws securing the stationary burr to the grind chamber.
Inspect and clean/replace burrs if necessary.
5. Remove the four screws at the top of the chute and remove the chute. Use a stiff non-metallic bristle
brush to remove any debris around the flapper.
6. Wash all parts in a mild solution of detergent with hot water and a stiff non-metallic bristle brush. Rinse
all parts thoroughly and allow them to air dry before reinstalling.
7. Carefully clean the grind chamber, dial plate assembly, and chute opening with a dry stiff non-metallic
bristle brush. Wipe with a clean cloth that has been soaking in a mild solution of detergent and
hot water.
8. Reinstall the chute onto the burr housing. Reinstall the stationary burr to the grind chamber.
9. Reinstall the spring and outer burr onto the auger rotor. Align the slot in the motor shaft with the rotor
and reinstall shear plate. Reinstall rotor cup and grind selector dial plate to the burr housing. Refer to
the “BURR ADJUSTMENT” section to adjust burrs.
