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, 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. (View Video Tutorial on Changing
Kony S/Robur S GFC Wire) The Major V uses different
GFC wires. (View Video Tutorial on Changing Major V
GFC Wire).
