  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.

  Melissa ReevesAug 21, 2025
  If your SunStar Sewing Machine experiences thread breaks, several factors could be responsible. It could be due to incorrect thread insertion or wrong needle installation (height or direction), so try reinserting the needle and threads. A damaged needle (bent, cracked, or with a distorted tip) can also cause this, so replace the needle if necessary. Check the thread tension, as excessive tension in the upper and lower threads or in the thread take-up lever spring can lead to breaks. Adjust the tension accordingly. Lastly, inspect the shuttle surface spring for cracks and replace it if needed.

  If the thread keeps getting cut while using your SunStar Sewing Machine, it could be due to several reasons. Ensure the thread is inserted correctly and the needle is installed properly, paying attention to its height and direction. A damaged needle (bent, cracked, or with an abraded tip) can also cause this, so replace it if necessary. Adjust the tension of both the upper and lower threads, as well as the tension and stroke of the take-up lever spring. Finally, inspect the shuttle surface spring for cracks and replace it if needed.

  Stitch skipping on your SunStar Sewing Machine can occur due to several factors. Make sure you are using a needle that isn't bent and is the correct size for the thread you're using; replace the needle if necessary. Check that the needle is correctly installed. Improper timing between the needle and shuttle, or an improper gap between the groove and shuttle point, can also cause this, so readjust the timing for the needle and shuttle. Also, adjust the tension and stroke of the take-up lever spring.

  If your SunStar Sewing Machine has a bad stopping position, it might be due to slackness in the main drive belt. Try adjusting the belt tension to resolve this. Also, check the synchro position and adjust its setting if it's improper.

  An error in trimming on your SunStar Sewing Machine can be caused by several factors. First, readjust the tension of the fixed mes if there's laxity in the exchanging tension between the movable and fixed mes. Second, if there's abrasion or a crack on the blade of either the movable or fixed mes, exchange them. Finally, readjust the position of the trimming cam if it's in the wrong position.

  If your SunStar Sewing Machine skips stitches, several issues could be the cause. A bent or improperly sized needle might be the problem, so try replacing the needle with the correct type. Ensure the needle is installed correctly; if not, reinstall it. The timing between the needle and shuttle could be off, or there might be too much clearance between the groove and the shuttle point. In these cases, adjust the timing of the needle and shuttle. Also, check the tension and stroke of the thread take-up lever spring and adjust if necessary.
