generally you tighten them until they bottom out "pse excluded" and let them out 3 full turns each , thats maximum , with a martin bow 4 turns are permissible
Actually, one of the nice things about Martin and a few others is that the limb bolts thread into a steel barrel nut and can be viewed from the side so you know when you are going too far. On some bows, too, it depends on whether the limb pockets are used to help keep the limbs aligned with the riser. Then you can't back them out as far. The limb bases must be kepts within the pockets
