4. Setup

1. Unpacking: Carefully remove the grinder from its packaging. Retain all packaging materials for future transport or storage.
2. Placement: Place the grinder on a stable, level, and dry surface. Ensure adequate counter space (Height: 24 inches, Depth: 11.5 inches, Width: 8.5 inches) and ventilation around the unit.
3. Power Connection: Connect the power cord to a dedicated 110-125V, 3 Amp, Nema 5-15 grounded electrical outlet.
4. Hopper Installation: Ensure the transparent bean hopper is securely seated on top of the grinder body.
5. Initial Cleaning: Before first use, wipe down the exterior with a damp cloth. Run a small amount of sacrificial coffee beans through the grinder to season the burrs and remove any manufacturing residues. Discard these initial grounds.

5. Operating Instructions

1. Filling the Hopper: Lift the hopper lid and pour whole roasted coffee beans into the transparent hopper. Do not overfill.
2. Adjusting Grind Size: The MDXS features micrometric grind adjustment. Turn the adjustment knob (typically located near the hopper base) to achieve the desired grind fineness. Turning clockwise generally results in a finer grind, and counter-clockwise for a coarser grind. Make small adjustments and test the grind.
3. Grinding Coffee: Place your portafilter or ground coffee container under the dispensing chute. Activate the grinding mechanism (refer to the specific model's power switch or dosing button). The grinder will dispense freshly ground coffee.
4. Dosing: The grinder may feature a timed dosing mechanism or manual operation. Adjust the dose as needed for your brewing method.
5. Stopping Grinding: Deactivate the grinding mechanism once the desired amount of coffee is dispensed.

6. Maintenance

Regular cleaning and maintenance are crucial for optimal performance and longevity of your grinder.

6.1 Daily Cleaning

• Unplug: Always unplug the grinder before cleaning.

• Clean Dispensing Chute: Use a brush or vacuum cleaner to remove any residual coffee grounds from the dispensing chute.
• Wipe Exterior: Wipe the exterior of the grinder with a damp cloth. Do not use abrasive cleaners or solvents.

6.2 Periodic Deep Cleaning (Burr Cleaning)

1. Unplug the grinder.
2. Remove Hopper: Carefully remove the bean hopper.
3. Access Burrs: Follow the manufacturer's instructions for your specific model to access the grinding burrs. This usually involves unscrewing or unlocking the upper burr carrier.
