I can't help you with a manual but there is a rule of thumb for bows. All this assumes that you have the right arrow for the bow in terms of spine and weight. For a recurve start at 8" measured from the deepest part of the grip. Shoot the bow. If it is noisey slip the top end of the string off the bow and give it a few twists to shorten it. You should be able to see what direction the string was twisted in when it was made. It's usually counter-clockwise. The bow should be a little quieter when you shoot it now. If you are still hearing a snapping or popping sound give the string a few more twists and shoot again. Ideally, you will reach a point where the sound is a muted "thump". Go slow and don't add too many twists at a time. The bow should get quieter and if you go too far it will get noiser again. 9" is about the max fistmele (brace height) for most recurves so if you get that far you need to rethink what is going on.
I'm sorry that I can't give you a set measurement for fistmele on your bow. The fact is that two apparently identical bows can require a different fistmele. Learning to adjust the fistmele for any bow is a matter of experience. You learn to hear what the bow is telling you. To make matters worse, once you find the quietest setting you may need to tweak it a bit to get best flight from a given weight/spine of arrow. It's all part of the fun though and before you know it you will be showing others how it's done. Oh, and before I shut up the starting point for a longbow is about 6 1/2" with a max of 8".
