So I see mt range is 40-70 lbs on my Mathews FX. I want to turn it up to 70 - not sure what its at now. Do I just turn them all the way tight until I can't turn anymore (within reason) and guess that is 70?
Exactly. My 70# bow maxed out is almost 72lbs. Just like Hoyts are notorious for getting 2-4lbs more than their "stated max weight". Just remember, what you do to the bottom, you do to the top, and, vise versa. General rule of thumb is that 1 complete turn is equal to 3lbs.
A.) Make sure there's no limb pocket locking bolts that need to be loosened before you start turning the limb bolts. B.) Don't advance one too far ahead of the other. I usually do no more than two turns on a limb before catching the other limb up two turns. C.) It may max at more than the stated 70 lbs. as others have pointed out but my experience with Mathews is that they're usually within 1/2 lb of their stated max. on my scale. D.) If the string and cables have crept you're going to be out of spec. and short of the max.
Hey Curtix, the FX is pretty easy, there are no limb pocket bolts or anything, just crank down the bolts within reason. Again as stated above, the top and bottom must be equal. I actually marked my bolts so help count the revolutions more accurately. Also I like get a little scale out and check the distances (gap between limbs and riser).
