  If the SunStar Sewing Machine skips stitches, first ensure the needle is correctly inserted. Replace the needle if it's bent or broken. Also, replace the needle if the thread is passing at the wrong position. Adjust the timing of the needle and hook. Adjust the thread adjusting device if the remaining length of the upper thread is short. Change the racing protection spring, if lower thread dropping from bobbin case becomes too short to go up. Adjust the working capacity of take-up lever spring, if you are unable to lift lower thread due to weak take-up lever spring.

Why is the upper thread pulled out when sewing starts on my SunStar KM-1060BL Sewing Machine?
- S
  Stephen KirbyAug 26, 2025
  If the upper thread is pulled out when sewing commences on your SunStar Sewing Machine, the upper thread tension might be too strong; adjust it. If the needle is too thick for the thread, check the needle thickness. Also, if the take-up lever pulls out the upper thread because the needle up and down position is too high, adjust the up-stop position of the needle.
