Hi everyone, I also just inherited a singer serger (14U64a) from my mother, who purchased it many years ago. She's passed away now and my sister held it a long time before giving it to me. Needless to say, I have no idea how it works and, of course, there's no manual. I did thread it successfully from the diagram on the door, but it doesn't have any needles. Does it require double needles? I will go to the links posted on the other posts, but I may be back for more help.
I also inherited a Janome New Home 620, which I cannot find listed anywhere!!! It's as though it never existed. Has anyone heard of this machine? I think it is an embroidery type machine, and, of course, there's no manual for that either.
It's frustrating having machines that don't work.
