5. Operating Instructions
5.1 Automatic Grinding
The grinder operates automatically using a gravity sensor. Simply invert the grinder over your food, and it will begin grinding. The blue LED light will illuminate during operation. Return the grinder to an upright position to stop grinding.

This image illustrates how the gravity sensor switch works: upright position turns it off, inverted position turns it on for grinding.
5.2 Adjusting Coarseness
To adjust the grind coarseness:
- Locate the adjustment knob at the top of the grinder (above the battery compartment).
- Turn the knob clockwise for a finer grind.
- Turn the knob counter-clockwise for a coarser grind.

This diagram demonstrates how to adjust the grinding coarseness from extra coarse to extra fine by turning the knob at the bottom of the grinder.
6. Maintenance
6.1 Cleaning
- Wipe the exterior of the grinder with a damp cloth. Do not immerse the grinder in water.
- The grinder is not dishwasher safe.
- For the transparent spice chamber, it can be hand-washed with mild soap and water after detaching from the main body. Ensure it is completely dry before reattaching and refilling.
7. Troubleshooting
- Grinder not working or stuck: If the ceramic grinding core becomes stuck with granules, turn the coarseness adjustment knob to the coarsest setting. This action helps dislodge any blocked particles, allowing the grinder to resume normal operation.
- Weak grinding or no operation: Check the batteries. Ensure they are inserted correctly with the correct polarity and have sufficient charge. Replace all 6 AAA batteries if necessary.
