Do a goggle search on your sewing machine brand/model # and buy a replacement manual for your current machine.

I posted that brand doesn't matter because it's all about you. I love Kenmore sewing machines--I have 3. But I also have a Singer Featherweight, an old Mountgomery Wards machine and one that my grandmother bought when I was 2. My sergers are White, Babylock, and Phaff. I bought my machines because they did what I wanted them to do and I liked sewing on them. Also I don't need the after sale dealer service. I used to sell sewing machines including teaching the buyer how to use it. And that was the same advice I told my customers--buy the machine that you like to sew on. Brand doesn't matter if you don't like to sew on that particular machine. In fact, I'd so far as to say that the dealer is more important than the brand of the machine.
Sewing machines are like cars. I loved my 1993 Ford Festiva; my dh hates it. I now love my "new" 1997 Ford Escort which I bought from Joy. Her husband hated driving it. They both are in love with her new (2005) Town and Country mini van which is a Chrystler.
