Welcome to the 7550 family ;-). I bought mine new 30 years ago. She's still my best friend in sewing machines. I hug her every time I use her. So wonderful. Good luck in finding the manual. If you have trouble reading something in the lousy PDF manual feel free to contact me and I'll see if I can help you in reading it. I honestly pretty much use a few of the decorative stitches and straight stitch so I'll fail you if you want to know about sewing functions ;-). But you can try me anyway. I heard the button hole isn't very good. I don't know first hand. There's also a 1471-7570 group on FB.
