How to improve the thread tightening quality on my SunStar Sewing Machine?
If you're experiencing poor thread tightening with your SunStar Sewing Machine, it might be due to weak tension in either the upper or lower thread; try adjusting the tension of the upper and under thread.

What causes ineffective sense of upper thread on SunStar Sewing Machine?
If your SunStar Sewing Machine isn't sensing the upper thread effectively, it might be due to a bad connection between the take-up lever spring and detecting plate. Clean these parts and adjust the tension of the take-up lever spring and connecting condition of detecting plate. Another cause may be a bad connection of the wire with the thread sensor plate, so reconnect the wire with thread sensor plate.
