Picked up a used pse omen Max last week . Didn't come with user manual and for some reason I can't get one to download. I understand the concept of the flex guard but is it suppose to be tuned to your bow? Are you suppose to tighten the bolt all the way or loosen / adjust it to bring your cables in closer. Also I noticed there are different elevations and holes for moving it farther back or forward. Any info is appreciated.
