I had this problem and it all came down to using the wrong backing. I kep trying to use tearaway on everything but WRONG. Using the proper backing corrects most problems. Good Luck!

Check that your bobbin thread is not wound too tightly or too loose. Also adjust your tension down a click at a time until it stops breaking, testing on scrap fabric. Singer provided manuals online. Look it up here: http://www.singerco.com/accessories/manuals.html

Clean away all the thread.

If you look through the Singers at Relics.com you may find your machine and order a manual so you can be sure the bobbin has been threaded and is inserted correctly into the machine.

It is possible the timing has to be adjusted - you can find this at sewusa.com
