Why does the upper thread keep breaking on my Necchi NC-103D Sewing Machine?

If the upper thread of your Necchi Sewing Machine breaks, there are several potential causes: * The machine might not be threaded correctly, so rethread it. * The thread tension could be too tight; reduce it to a lower number. * The thread may be too thick for the needle; select a larger needle. * The needle might be incorrectly inserted; remove and reinsert it 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 it. * The needle could be damaged; insert a new one.
