Why is the lower thread breaking on my Bernina Sewing Machine?
Lower thread breaks on your Bernina Sewing Machine can occur if the bobbin case is damaged, so replace the bobbin case.

Why is the needle breaking on my Bernina 740 Sewing Machine?
If your Bernina Sewing Machine needle breaks, it might be because the needle is incorrectly inserted. Make sure to insert the needle with the flat side to the back as far as it will go and tighten the screw. Also, avoid pulling the fabric; instead, feed it evenly.
