Having trouble making adjustments to your grinder? Find out what might be going wrong and how to get the adjustment knob moving. If the grinder adjustment knob seems to be stuck in place, please note that you must press down and turn simultaneously, sort of like opening a medicine bottle. If the knob still won’t turn when pressed down, try turning it in the opposite direction as well. This may help loosen up the mechanism and get it moving.
