Select the screw diameter that appears to be the correct size. Insert screwdriver tip into screw-starter and hinge screw into other end. 3. Make sure the leaves of the hinge are properly engaged. Insert screw and tighten. DO NOT FORCE. If screw does not tighten easily, then try a different screw.
Forcing an incorrect size screw may damage hinge threads. Keep away from children. Don’t store in direct sunlight. Remove glasses before adjusting. Discard if dull and inspect before use.
