OK....it's difficult to explain, but not difficult to do. This rest is very basic so the adjustment isn't quite as finite and simple as on some others. First, the cock vane goes down, and if you have much helix on your vanes......you're gonna hit the prongs. You gotta fletch 'em straight or a slight offset, no helical.

Now, to tune this rascal. The basics are the same.......left, right, up and down. Head to the shop to do some paper tuning. Depending on the tear, loosen the small allen screw on the horizontal post moving the rest either left or right. Be careful, now....because this also moves up and down. Same screw. Ideally, you don't want the prongs standing straight up. Another way to adjust up and down is to loosen the mounting bolt on the riser and move the whole thing. It's not all that tough, but since it's so basic it can get aggravating. Just really take your time and you can get it. I shot those style rests for years. It can be done, just be patient.

Remember, when you loosen the allen screw to move it left or right, it will also rotate up and down, so hold on to it and try not to let it move up or down. Hope this helps. Good luck!
