If you pull
the grinder away from the metal coffee catcher there is a black 5 star dial on
the base of the top half. If you turn it clockwise this will make it finer,
turn it counter clockwise and it becomes coarser. Grinders are set roughly at
the correct position when they are packed but sometimes move when being
shipped. Only move
the dial slightly in each direction until you have the correct grind. Do a few
test coffees until you have the grind right. Once it is set it rarely needs
readjusting again. You will know when you have the correct grind by watching
