Advice on changing draw weight compound bow please

IVRZ

Hi all
I got a nice compound recently a Hoyt. Second hand but a nice bow. Its my first compound and i want to lower the draw weight, which is adjustable from 45 to 60 lbs. I think at the moment its at the higher end and very hard to draw.
I understand that the weight is adjusted by loosening or tightening the limb bolts (if thats the right technical term?).
Does anyone know how much I can loosen these? Will they part company with the riser if i loosen them too much? I dont want bits of bow flying all over the place. Or maybe they just loosen out to a certain point and no more?
I tried to contact Hoyt but that part of their site is down for a while.
All advice greatly appreciated. Thanks:)
Heres a pic of the setup

Yup, Quicks are pretty good for getting back about gear advice, hope ya get the poundage down.

Just be careful, those things can go bing pretty quick with too many turns of a screw!
