Singer 400w1 - Looking for a manual and troubleshooting help!
Hi -- I just recently purchased a Singer 400w1 and am looking for some troubleshooting help. It runs like a champ except for one little (huge) problem. The tread breaks at the needle as it is coming up out of the bobbin case. I get a couple of really really nice stitches and than BAM -- all cut up. I have done the usual things to it, changed the needle, cleaned out the bobbin case, changed the thread, tested the tension. The needle seems to slide up the top hook/loop in the bobbin case but I don't know if it's suppose to do that or not. I am about to take apart the bobbin case and while I am intimidated I didn't pay very much for the machine. I sure would like it to work though. Thoughts? I am also looking for a manual and someone in the SF Bay area who might be able to work on it.
