Luke,
On mine, the large gears have a black mark on it about midway in the travel. The small gear on the pot has either a black mark or an arrow molded in the plastic. With the handles about mid point, the marks line up. That's the way I found it, and that's the way I left it. I was tempted to purposely misalign them such that the pot would turn down further, but not knowing all the consequences of such a move, thought that might not be a wise idea.
G, Thanks for the information.
