If you're experiencing skipped stitches or thread unraveling at the start of sewing, consider the following: * Reduce the tension or lower the position of the thread take-up spring. * Adjust the pretension. * Sharpen or replace the knives. * Replace the needle with a thinner one. * Replace the anti-spin spring if the bobbin spins loosely. * Use the slow start key and adjust the needle up stop position. * Turn on the 'Prev. thread away' function and adjust the upper thread trailing length. * Replace the needle plate or presser foot for better material press. * Lower the presser foot before starting and raise it after stopping.
Why are my Brother Sewing Machine upper and lower threads breaking?
If the upper and lower threads are breaking, several factors could be at play. First, check the needle to see if the tip is bent or blunt; if so, replace it. Ensure the needle is installed and threaded correctly. If the oil gauge is low, add more oil. You may also need to adjust the upper or lower thread tension or adjust the position of the thread take-up spring. Finally, check the thread path and smooth it with sandpaper or replace any damaged parts.
