Google it and you should find some good info, another thing you can do is go to Mathews website and download a owners manual. When I owned my Switchback, I got the users manual out and it tells you how to tune your cam and all of the specs to check. First check axle to axle, then your brace height. Then you can line up your cam. My Switchback also likes a little lean in the top idler, then when at full draw it would straighten out, don't ask me why but it liked the lean. You are going to need a bow press so you can put twits into your yoke, string and or buss cable to get things where they need to be. At the least you can purchase a portable bow master bow press for about $40.00. Another thing you might want to check and maybe you already have is if you are using the correct spined arrow.Good luck, I hope everything works out for you.
