5. Operating Instructions
Follow these steps for safe and effective grinding:
- Prepare Material: Ensure the material to be ground is completely dry. The grinder is designed exclusively for dry materials. Avoid wet or oily substances.
- Load Material: Open the upper cover by releasing the lockpins. Place the desired amount of material into the crush cabin. Do not overfill; the maximum capacity is 300g.
- Secure Cover: Close the upper cover and firmly secure both lockpins. Ensure the cover is tightly sealed before proceeding.
- Set Timer: Rotate the timer knob to the desired grinding duration (up to 5 minutes). For optimal results and to prevent overheating, it is recommended to grind intermittently, especially for harder materials. Grind for short bursts (e.g., 30 seconds), then allow a brief interval (e.g., 10 minutes) for the machine to cool before continuing.
- Start Grinding: The grinder will start automatically once the timer is set. The power indicator light will illuminate.
- Monitor Process: Observe the grinding process through the transparent window on the upper cover.
- Finish Grinding: The machine will stop automatically when the set time elapses.
- Retrieve Powder: Once grinding is complete and the blades have stopped completely, release the lockpins and open the upper cover. Use the powder disposal handle to tilt the machine body and facilitate powder retrieval.
- Overload Protection Reset: If the machine stops unexpectedly due to overload, simply press the red reset button on the base to resume operation after allowing a brief cooling period.
