3. Setup

1. Unpacking: Carefully remove all components from the packaging. Retain packaging for future transport or storage.
2. Placement: Place the grinder on a stable, flat, and dry surface. Ensure adequate ventilation around the unit.
3. Hopper Installation: Securely attach the bean hopper to the top of the grinder. Ensure it is properly seated and locked into position to prevent accidental dislodgement.
4. Power Connection: Plug the grinder into a grounded electrical outlet. Verify that the voltage matches the specifications on the product label.
5. Initial Cleaning: Before first use, wipe down the exterior with a damp cloth. The hopper and burrs can be removed for a more thorough initial cleaning if desired (refer to Maintenance section).

4. Operation

1. Fill Hopper: Pour fresh, whole coffee beans into the bean hopper.
2. Power On: Locate the power switch (typically on the side or back) and turn the grinder ON. The LCD display will illuminate.
3. Select Dose: Use the controls on the LCD multi-function display to select your desired dose (e.g., single or double espresso shot). The display allows for precise adjustment of grinding time or weight.
4. Adjust Grind Size: Use the micrometric grind adjustment knob (usually located near the hopper) to set the desired fineness for your espresso. Turn clockwise for finer grind, counter-clockwise for coarser. Make small adjustments and test the grind.
5. Position Portafilter: Place your portafilter securely into the portafilter holder beneath the dispensing chute. The LED illuminated work space will assist with proper alignment.
6. Start Grinding: The grinder is designed for on-demand grinding. Once the portafilter is in place, the grinding process will typically start automatically or by pressing a designated button on the control panel.
7. Automatic Stop: The grinder will automatically stop once the programmed dose has been dispensed.
