Cleaning and Maintenance
- Disassembly: Unscrew the bottom catch cup and carefully remove the burr assembly components.
- Brush Cleaning: Use the included cleaning brush to remove any residual coffee grounds from the burrs and internal components.

Troubleshooting
- Inconsistent Grind: Ensure the adjustment nut is securely tightened to your desired setting. Check for any trapped coffee beans between the burrs.
- Difficulty Grinding: If the handle is hard to turn, the grind setting might be too fine for the beans. Adjust to a coarser setting. Ensure the burrs are clean and free of obstructions.
- Static Buildup: A small amount of static is normal. To reduce static, lightly mist the coffee beans with water before grinding (Ross Droplet Technique).
