I checked on my old PSE Mach6. It took 17 full turns from bottem till the bolts came off. I did it witout strings or cables attached as you can understand. Than i tood a close look at my Mathews' . The bolts are about the same length and i guess the tread thats on them also.
When i have to put my Mathews' in the bowpress i allways untighten the limbs 5 turns.
See if you can get a manual or ask the manufacter of your bow by email.
Dont be scared to turn it back 5 or 6 turns tho. It should easely be done.
