adjustable numbered ring on the adjustment disk. This
numbered ring may be used to indicate where the burrs

Grind Flow Control Wires
Your Major V, Robur S, and/or Kony S allows different wire inserts to be used in the outlet insert
to control the flow of grounds out of the grinder. The Hybrid grind flow control (GFC) wire,
installed by default, is the best choice in almost all cases. If excessive clumping is occurring,
you may want to try the Anti-Clumping GFC wire. If there is a high amount of static, you may
want to try the Anti-Dust GFC wire. The Anti-Clumping GFC wire, Anti-Dust GFC wire and
instructions on how to install them are found in a small plastic box that came with your grinder.
The Kony S and Robur S use the same GFC wires. The Major V uses different GFC wires.
