Singer 111w 155 cutting thread in first few stitches

[teched]

You are probably right.  I have had this machine about three years and have about 6 hours of sewing time on it.

I will back up what CowboyBob says and check the hole of the feed dog.  Mine was a combination of the feed dog hole being a bit too small for the thread and needle I was pushing through it (#138 bonded polyester).  Luckily my machine came with a few sizes and so I changed out to a bigger hole on the feed dog.  Also, I noticed that my hook wasn't as close to the needle as it should have been and actually pierced the thread as it tried to hook it.  That was causing breaks and also binding on my hook.  Re-timed the needle and hook and changed the feed dog and have been running good since (Thanks to Uwe's videos for timing, huge help).
