  3. Attach Portafilter Holder or Dosing Cup:
    • For direct grinding into a portafilter (54-58mm compatible), attach the portafilter holder to the grinder's outlet.
    • Alternatively, place the 75g dosing container directly under the grinding outlet. The magnetic base ensures it stays in place during grinding.

Maintenance

Regular cleaning ensures optimal performance and extends the lifespan of your grinder.

  1. Daily Cleaning:
    • Brush off any remaining coffee powder in the grinder using the included soft brush.
    • The coffee bean hopper, hopper lid, grinding chamber, and portafilter cradle holder are all washable. Rinse them thoroughly with water and dry with a cloth.
    • For the main body, wipe with a damp cloth and then dry with a clean, dry cloth.
  2. Deep Cleaning (Burrs):

    • Rotate the upper conical burr counterclockwise to remove it.
    • Use the soft brush to clean both the removed burr and the conical burr inside the grinder.
