2. Secure Lid: Close the top lid and ensure the handle is properly attached.
3. Grind: Hold the grinder firmly with one hand and rotate the handle clockwise with the other. Continue grinding until no resistance is felt, indicating all beans have passed through the burrs.
4. Collect Grounds: Once grinding is complete, gently twist and remove the magnetic catch cup to access your freshly ground coffee.
