Loosen the screws for the hinge pin holders, push the arm towards the hinge pin holder and tighten it. Then press the arm towards the other hinge pin holder and tighten it.This prevents the hinge pin holders from tweaking when you tighten them, making them square to the arm. Result: arms move freely.
