Usage Features
The grinder is designed for user-friendly operation with several key features:
- Touch Screen Display (5): The main interface for all settings and operations.
- Grinding Adjustment Knob (4): Allows for precise adjustment of the grinding degree. Turning clockwise makes the powder finer, while counter-clockwise increases grain size. This adjustment is stepless and should be done gradually.
- Filter Holder Fork (8): Supports the filter holder during grinding. Its height can be adjusted by loosening two screws beneath it.
- Dose Selection:
- Selected Dose Grams Display (A): Shows the current dose in grams.
- Grams Decrease Button (B) / Grams Increase Button (G): Used to adjust the dispensing time of the selected dose in increments of 5 hundredths of a second.
- Dose 1 Selection (C) / Dose 2 Selection (H) / Dose 3 Selection (D): Buttons for selecting pre-programmed doses.
- Continuous Dose Selection (I): Allows for manual, continuous grinding as long as the button is pressed.
- Dose Adjustment Lock (E): A feature to block dose adjustment, preventing accidental changes.
- Preliminary Operations:
- Coffee Bean Container (2): Inserted into its seat and locked with a screw.
- Opening/Closing Tab (3): Controls the flow of coffee beans from the hopper to the grinding mechanism.
- Container Lid (1): Covers the coffee bean container.
- Grinding Mode (Weight/Time): The grinder can operate in two modes:
- Grinding by Weight: The main screen is red, and doses are dispensed based on a pre-set weight.
- Grinding by Time: The main screen is green, and doses are dispensed based on a pre-set time.
- Safety Features:
- The grinder will not start if the filter holder is not inserted correctly.
- Automatic dispensing can be paused by pressing the selected dose button or the front activation button.
- The system resets if grinding is not restarted or the filter holder is removed within a specified time (30 seconds for paused doses, 5 seconds for continuous dispensing).
- An alarm (F) can be activated to indicate when the grinder burrs need replacement.
- Menu Access (J): Provides access to the main menu for advanced settings.
- Technical Menu Access (M): Allows access to technical settings, often password-protected.
- Password Protection: The technical menu and dose adjustment lock can be secured with a 4-digit password.
- Language Selection: The display language can be changed from a list of available languages.
- Standby Mode: The grinder can be set to enter standby after a period of inactivity, with adjustable delay time.
Maintenance Features

- Use a vacuum cleaner or compressed air if necessary.
- For complete sanitization, use detergent tablets for grinders or food-approved products.
- Grinder Maintenance (Burr Replacement):
- Frequency: Check and replace grinders every 500 kg of coffee.
- Procedure:
- Disconnect from power supply.
- Remove the bean container.
- Loosen the screw on the lid and the screws securing the upper grinder holder.

- The counter can be reset after burr replacement.
- Filter Holder Fork Calibration:
- A calibration procedure is available to ensure accurate weighing.
- Involves using a sample weight and pressing "TARE" and "CALIBRATION" keys.
- The display indicates success (green "V") or failure (red "X").
- Note: This intervention is only necessary if calibration precision is lost.
- Partial and Absolute Counters:
- Partial Counters: View kilograms dispensed for each dose and can be reset.
- Absolute Counters: Non-resettable counters for each dispensed dose, providing total usage data.
- Factory Settings Reset: Allows restoring the appliance to its original factory settings.
Safety Warnings for Maintenance:
