Did it come with the video. If so, watch it. It will explain it all. My only suggestion is that it will seem like you have to knock high to get good clearance. Dont worry, paper test it and set it to where it is making a slight high tear. Something else, set the tension on the lock nut just so it falls slowly on its own. If you make it too tight it will slow the rest down, if it is too lose it will be loud.

You will love that rest.
