Why does my thread keep jamming?

The thread could be jamming for several reasons.

The upper thread could be tangled.
Remove the thread completely from the machine.
The correct size spool cap should be used for the size of the thread spool.
Re-thread the machine according to the directions in the manual.
Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race.
Remove any loose threads or lint in the shuttle race.
The combination of the needle size, thread size and fabric is incorrect.
Be sure to use the correct size needle and thread for the type of fabric that you are sewing. (Example: Denim-size 16 needle and 40-50 heavy-duty thread )
