were the limbs are atached to the bow you tighten to add weight and loosen to decrease but i recomend a pro shop do it because they can get it to exactly what you need and theres a chance you can over tighten and break the limbs or over loosen and undo the limbs

It’s a pretty standard procedure. The limbs are held in place with big allen screws. As you tighten these – meaning screw them into riser the bow weight goes up. As you unscrew them the bow weight goes down. The manual for your bow should tell you how many turns you can back the limbs out. This is actually an important thing to know because most PSE bows are “pre – loaded” meaning that there is tension on the string even if the screws are almost all the way out. Many manufacturers do this to increase power of the bow without increasing the fistmele. (the distance from the riser to the string when the string is at rest)

Generally, a full turn on the screw is about 4 – 5 pounds, but your manual should say. If you don’t have the manual, call PSE or talk to an archery pro shop. Also, pro shops sell T handle allen wrenches for making this easier to do – if you are going to mess with the weight of your bow often I would highly recommend getting one.

If you don’t know how many turns out from the riser you are right now, then screw the limbs all the way down and just back them off to your desired weight from there.

Thinkingblade

There will be a bolt that holds the limbs to the riser. One on each limb.
to decrease the bow strength turn each limb bolt to the left one full turn each. Check and see if that is enough. If not, do it again until the results you are seeking is achieved.
