Cleaning La Pavoni Burr Coffee Grinder

You'll need to remove the hopper and grind out all the beans. Then, with the lock tab depressed (if it has one), unscrew the grind adjusting collar out of the body. Once it's out, there are three screws (sometimes only two) holding each burr. Remove screws and separate the burrs. Clean away!
Be very careful putting it back together so that you don't cross-thread the collar into the body. Clean threads can help this.
Good luck!
