1. Filling the Grinding Bowl
- Ensure the grinding bowl is clean and dry.
- Add your desired ingredients (e.g., whole coffee beans, dried herbs, spices) to the grinding bowl. Do not overfill; the maximum capacity for coffee beans is approximately 3 oz (enough for 12 cups).

2. Selecting Speed and Grinding
The grinder features two speed settings: High and Low.
- High Mode: Ideal for harder ingredients such as coffee beans, nuts, and hard cheeses.
- Low Mode: Perfect for softer ingredients like herbs and spices.
To operate, select your desired speed using the switch on the front of the base, then press down on the lid to activate the grinding process. Release pressure to stop.

3. Achieving Desired Fineness
The grinding time determines the fineness of your grind. Monitor the consistency through the transparent lid.
- French Press: Approximately 10 seconds.
- Drip Coffee: Approximately 15 seconds.
- Pour Over: Approximately 20 seconds.
For very fine grinds, you may need to pulse the grinder for slightly longer periods, allowing short breaks to prevent overheating.

- Carefully remove the lid, then lift out the removable grinding bowl.
- Pour the ground ingredients into your coffee maker, storage container, or recipe.
- If storing, use the provided storage lid to seal the grinding bowl.
