Cannot Turn Hand Wheel
No matter how hard you try to keep the bobbin area free of loose threads and lint, you may get a jam.
It is usually caused from a piece of thread that is caught in the bobbin area.
1. Turn the power off.
2. Remove the bobbin case.
3. Standing behind the machine, facing the hand wheel, rotate the hand wheel clockwise to back
the jam out of the bobbin race. (This may take some work to get it worked free.)
4. Normally when the thread is dislodged you will be able to make a full rotation with the hand
wheel.
5. Clean the bobbin area with a soft brush.
