Why is the upper thread breaking on my Euro-Pro INTELLI SEW 9136C?

The upper thread may break due to several reasons: * The machine might not be threaded correctly, so rethread it. * The thread tension could be too tight; reduce the thread tension (lower number). * The thread might be too thick for the needle; select a larger needle. * The needle might not be inserted correctly; remove and reinsert the needle with the flat side towards the back. * The thread could be wound around the spool holder pin; remove the reel and wind the thread onto the reel. * The needle might be damaged; replace the needle.
