The thread doesn't break and it doesn't get tangled in the bobbin case. It's nothing I've ever seen before and therefore I'm stumped!
The other manual I have says to use a system 1738 needle with the long groove facing to the front.
I just happened to have some Schmetz needles that have this number on the packet, but they are round shank. There was a giant (denim weight) flat shank needle in it when I got it but we suspected that this needle wasn't right, however changing the needles hasn't seemed to help the problem, nor has it made the problem worse.
Any clues?
My sewing machine did that, stitch one stitch and the rest came out, I had the needle threaded in the wrong direction I was suppose to go from Right to Left. try the opposite of what you have. Good Luck!
