Why does the upper thread keep breaking on my Euro-Pro Shark 803XC Sewing Machine?

If the upper thread of your Euro-Pro Sewing Machine is breaking, several factors could be at play. First, ensure the machine is correctly threaded. If the tension is too tight, reduce it. For thread too thick for the needle, select a larger needle. Also, make sure the needle is correctly inserted with the flat side properly oriented. Check if the thread is wound around the spool holder pin, and if so, remove the spool and rewind the thread. Lastly, a damaged needle should be replaced.
