3. With the retaining bolt LOOSENED and NOT REMOVED, use the Phillips screw driver to adjust the frame lock bar. Rotate left or counter clockwise to tighten. Rotate right or clockwise to loosen the frame lock.(Each time only turn 1/16 of turn. Don't over do it.)
MAKE SURE THE SCREW DOES NOT UNTHREAD, BUT RATHER TURNS THE WHOLE ADJUSTMENT BAR. IF THE BAR DOES NOT MOVE, USE AN ADJUSTABLE CRESCENT WRENCH TO TURN THE BAR.
