Alternately inserting the winding rods into the holes of the springs winding cone, rotate the winding cone downward toward the floor, 1/4 turn at a time, until the required number of complete turns for your door height is achieved. As the last 1/8 to 1/4 turn is achieved, securely hold the winding rod while tightening both set screws in the winding cone to
