To remove the stationary burr, use the two small magnets provided in the box. Place the magnets next to each other on the stationary burr’s face, and lift gently; this should loosen it enough to pull it out. For the rotary burr, firmly tap the auger against the palm of your hand to release it.
Radial screws were phased out starting with batch 5, so they are no longer needed or included in the newer models.
