Maintenance

Regular cleaning ensures the longevity and consistent performance of your Normcore Manual Coffee Grinder V3. Do not wash the burrs or internal components with water, as this can lead to rust and damage.

  1. Disassembly: Unscrew the bottom grounds catcher. You may also carefully remove the burr adjustment dial and the burr assembly for a deeper clean if necessary.
  2. Brush Cleaning: Use the provided cleaning brush to gently brush away any residual coffee grounds from the burrs, internal chamber, and grounds catcher.
  3. Air Blower: Use the provided air blower to dislodge any stubborn fine particles from the burrs and internal mechanisms. Direct short bursts of air into the burr area.
  4. Reassembly: Once clean, reassemble the grinder by carefully placing the burr assembly back, followed by the adjustment dial and the grounds catcher. Ensure all parts are securely tightened.

Troubleshooting

Problem Possible Cause Solution
Difficulty turning crank / Grinder jammed Beans are too hard or burrs are set too fine; obstruction in burrs. Adjust to a coarser setting. Disassemble and clean burrs to remove any foreign objects or stuck beans.
Inconsistent grind size Burr assembly not tightened correctly; burrs are dirty. Ensure the grounds catcher and adjustment dial are securely tightened. Clean the burrs thoroughly.
Excessive static cling of grounds Dry beans or low humidity. Lightly mist beans with a few drops of water before grinding (Ross Droplet Technique). This is a common technique and does not harm the grinder.
