"My Bobbin Thread Keeps Breaking"

Q.I purchased a box the label says admiral L24 on it and it works wonderful in my Pfaff 2140/70. I mentioned I would like a thread that does not leave a lot of fuzz and I purchased a box of masterpiece L style # 151 thread. I’m just starting to use it and it seems to be giving me some problems. I seem to stitch out for a bit and then the bobbin thread breaks away. I have left the cardboard on the outside of the thread and I have also tried one without the cardboard on. I have also changed my needles and still am not having any luck. The item I'm stitching out is delicate and the look is great. Any suggestions to help me out, I would really appreciate it.

A.We recommend loosening your bobbin tension if your bobbin thread keeps breaking like this. Do do that, please follow these steps:

  1. With a permanent marker, mark a dot on the bobbin case where the bobbin screw is currently pointing to. This is to remind you where you started.

  2. Loosen the bobbin tension by turning the bobbin tension screw by 1/4 turn. Turn to the left (counter clockwise). That should take care of it. Many machines are set to have a very strong polyester thread in the bobbin and therefore need to be adjusted for a fine cotton thread. View our diagram on loosening bobbin tension
