Backing out linbs for son

[paka]

Aloha All ,
A friend just gave me a hoyt Raider , Im guesiing made in the 90's thats in really good condition. On the limbs it says its in the 35 to 50 lb. range. I tightned the limbs all the wall up and started backing them down for my son to try to pull back . Well its to the point I need some knowledge here. Is it possible to back the limb bolt out all the way , must be . What happens if that occurs?????[] Should I get a bow vise to compress the limbs, take the string out ,release the vise, then back the bolts out and mark them where the maximum backing out would be? How would you all go about dialing down weight?? My son can probally pull 35 lbs back so its gonna be close.
Also if anyone has any sites besides Hoyt for this bow or past history with them please let us know
Mahalo Everyone

If you back the bolts out all of the way the limbs will come out of the pockets.

How dangerous could that be????

Very Dangerous! The bow could come apart in your face. Take the bow to a professional and get his advice on how far the limb bolts can be turned out without putting you or your son in danger.

Another thing about these older bows is to avoid shooting real light arrows. The light arrow is almost like dry firing a bow designed for 500 grain arrows.
