How do you fix a brother embroidery machine style number 655, thread won't cut by itself

I figured out the solution for this issue. It all has to do with the threading. And I mean literally follow the instructions word for word. Most importantly is the Bobbin thread. make sure to thread the bobbin through the case eyelet.

If you tighten up your needle thread, reduce the tension of the needle thread.
For embroidery, and zig-zag, and because the needle makes side movements, it needs more needle thread.
So try to keep you needle thread not very tight,
and tight up your bobbin case tension more, so that the two threads meet under the meterial.

The fact that your machine is turning hard says you still have some thread inside the machine that is binding up and activating the safety device. It must turn easily before it will work properly again.
Sometimes the machine must be disassembled to remove these threads.
