Operating Instructions
1. Filling the Hopper
Lift the hopper lid and pour whole roasted coffee beans into the hopper. Do not overfill. Replace the lid securely.
2. Grind Adjustment (Nice Grind Control Dial)
The MI40 Luxe features a stepless grind adjustment dial for precise control. To adjust the grind fineness:
- Turn the grinder ON using the power switch.
- Rotate the grind adjustment dial. Turning it clockwise results in a finer grind, and counter-clockwise results in a coarser grind.
- For espresso, start with a fine setting and adjust incrementally based on extraction time and taste. It is recommended to adjust the grind while the burrs are running to prevent jamming.
