How to remove the grind adjustment knob from the BORK CG700 (j700) coffee grinder?
In different units, the handles are fixed in different ways, there are no universal methods here. Try gently inserting a knife blade or a piece of plastic (like a used credit card) into the gap between the handle and the grinder. Also, lightly pressing the tool, while shaking the handle to the sides, you need to try to move it away from the axis of the attachment.
