It says nothing about it in the owners manual. I read through it a couple times, I didnt see anything about it. The info you need is on the round hang tag that was attached to the riser.

To replace string, cables or install peep sight, back the limb bolt out 5 turns on one end then alternate to the other end, repeating this process until the end of the limb bolt is just visible in the limb bolt viewing hole in the riser (approximately 3 threads visible). String tension will be minimal allowing you to work on the bow as needed.
