How to fix error in thread tightening on SunStar SPS/D(C)-B1202-03 Sewing Machine?
- RRebecca LiAug 5, 2025
If you're experiencing an error in thread tightening with your SunStar Sewing Machine, it might be due to weak tension in either the upper or lower thread. Try readjusting the tension of both threads. Also, improper timing between the needle and shuttle can cause this issue, so readjust the timing for the needle and shuttle.
