BULK COFFEE GRINDING
1. Turn the selector knob to align the arrow with the desired grind. 2. Raise the top lid and add the whole bean coffee. Close the top lid. 3. Locate the back of a bag behind the dispense chute or insert the brew cup. (These bulk coffee grinders will not operate unless the bag/brew cup sensor is activated) 4. Allow the bag to rest on the screen beneath the chute. 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.
ADJUSTMENT 1. Place a brew cup in place or an empty bag on the screen, with the back of the bag behind the dispense chute. 2. Start the grinder to clear the grind chamber. Leave grinder “ON”. 3. Turn the Grind Selector knob to the “TURKISH” (or “1”) 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 “TURKISH” (or “1”) 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 “TURKISH” (or “1”) position, back off the screw to the left (counterclockwise) just until the metallic whine ceases. 8.Turn-off the commercial coffee 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 “TURKISH” (or “1”) 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.
