Burr cleaning – Rancilio Rocky

  1. Unplug the unit.
  2. Remove the bean hopper cover.
  3. Remove the 3 screws located in safety guard inside the bean hopper.
  4. Lift up the bean hopper away from the grinder.
  5. Spin out the brass plate where the 3 screws were attached.
  6. Vacuum the coffee grinds from the threads on the brass plate and from the grinding chamber.
  7. Clean the burrs on the brass plate and in the grinding chamber with a sharp knife (be careful not to cut yourself).
  8. With cotton swabs dipped in olive oil (or vegetable oil), remove ALL the coffee grinds from the threads on the brass plate and on the threads in the grinding chamber.  It is critical to remove ALL coffee grinds.  If you leave coffee in the chamber, you will not be able to screw down the brass plate enough to get a finer grind.
  9. Once all the grinds are removed, screw down the brass plate until you see the burr inside the grinding chamber move. Typically, the top brass plate will not move any further.
  10. From the front of the grinder, look for the forward most screw slot in the brass plate and rotate the brass plate counter clockwise until that screw slot is to the right of the grind selector button.
  11. Place on the bean hopper so the screws align with the screw holes so that the lowest number setting is to the front.
  12. Tighten the 3 screws. Make sure not to over tighten as this will crack the hopper.
