I downloaded one... and it has threading instructions, but no troubleshooting.
Do you put the flat side of the needle towards you or away from you?
The flat side of the needle needs to go away from you on the back side. The curved part needs to be to the front. The 401 doesn't require anything special. I would also suggest keeping with a metal bobbin.
