4. Operating Instructions
4.1 Adjusting Grind Size
The KINGrinder P2 offers precise grind adjustment for various brewing methods. The adjustment dial is located at the bottom of the burr assembly.
- To adjust, turn the adjustment dial.
- Turning clockwise (tighter) results in a finer grind.
- Turning counter-clockwise (looser) results in a coarser grind.
- Each "click" represents a fine adjustment of 0.0333mm. There are 30 clicks per full rotation.
Refer to the table below for recommended starting grind settings:
| Brewing Method | Grind Size | Approximate Clicks from Zero (Finest) |
|---|---|---|
| Espresso | Very Fine | 10-20 clicks |
| Moka Pot | Fine | 20-30 clicks |
| Pour Over / Drip | Medium | 30-50 clicks |
| French Press / Cold Brew | Coarse | 50-70 clicks |
Note: These are starting recommendations. Optimal grind size may vary based on bean type, roast level, and personal preference. Experiment to find your ideal setting.
4.2 Grinding Coffee Beans
- Ensure the grind adjustment is set to your desired coarseness.
- Remove the handle and open the top lid of the grinder.

| Inconsistent grind size | Grind setting not properly locked; burrs are dirty; worn burrs (unlikely for new product). | Ensure the adjustment dial is securely clicked into place. Clean the burrs. |
| Static cling of grounds | Dry air conditions; certain bean types/roasts. | Lightly mist beans with a few drops of water before grinding (Ross Droplet Technique). Tap the grinder a few times before opening the collection cup. Use the cleaning brush to dislodge grounds. |
