If you don't have a manual for it there are plenty of places that sell them online pretty cheap. It may also need a tune up too. I just bought one a few weeks ago off of craigslist, it is a kenmore that does 3 stitches. My best guess is that it was made in the early 80's. I'm still trying to figure out how to work it, the last time I used a sewing machine was 21 years ago in home ec. I've figured out how to do the top thread but not the bobbin thread yet. I figure if I cannot figure it out I am going to put an ad on craigslist to find someone to help me. I bought mine to make hammocks for our rats and maybe the chins.
