Why does the upper thread keep tearing on my Lumina ESM008 Sewing Machine?

If the upper thread of your Lumina Sewing Machine tears, it might not be threaded correctly, or the tension could be too high. A bent, blunt, or incorrectly inserted needle can also cause this. Ensure the fabric is being transported properly during sewing, manually pushing it forward if needed by lowering the feeder. The thread might also be too thick or thin for the needle.
