I believe I have the manual but am not at home until later. Will check to see and attach for you. I had one of these and it had a cracked gear but still ran as quiet as ever. I really like the supernova's with the round needle plate. They are also really nice machines. Most always stiff from old sewing machine oil but once that is taken care of they are wonderful to sew on. Will check for the 515 too!
