Turn the screws that go through the limb into the riser. You need a allen wrench. Just make sure you turn each of the screws on the top and bottom the same amount. I'm not sure with way you need to turn it to increase or decrease weight but I'm pretty sure its clockwise to increase and counter clockwise for decrease.
Usually they are 2-3# per full turn. Best bet is to tighten it down all the way, then back each one out to the desired weight. If I'm not mistaken, Mathews recommends not going past 4 full turns.
Again I'm actually not 100% sure but depending on what bow you have think its about 3.75-5 lbs for each full rotation of the screw. The couple times I've done it I've had a scale to measure the weight.
Ok im a Mathews tech for a proshop only crank each bolt a half turn at a time do the top first then bottom in half turns or you could throw the timing off . Either way you go up or down in pounds only do half turns never exceed full turns on each bolt.
Each half turn is a pound to a pound and a half a full turn is usually 2 to 3 pounds like fitz said. And do not exceed 5 turns backed out the bolts can strip or the riser were the bolts screw in can crack and cause serious injury. Its best to max it out then back each limb off a half turn starting at the top.
When i was becoming a tech mathews told us never exceed 5 turns backed out never and always back it out in half turns due to the timing and its best to start with the top limb thats how they taught us anyway.
Does Mathews offer a DVD on fine tuning and setting up there bows? For that matter does any company do that anymore? I am just starting at a small outdoor store and learning the basics. The store doesn't offer any of the high end bows but I would like to learn about some of the newer models of bows instead of having to watch a DVD from the early 1990's. The basics are the same but technology is leaps and bounds ahead of this DVD. Any info is greatly appreciated.
