What causes thread break before trimming on SWF E-Series?
- Ssamantha50Sep 12, 2025
A thread break before trimming on your SWF Sewing Machine can be caused by the upper thread being too short (adjust upper thread tension), a dent or damage to the movable blade (remove dent using whetstone or sandpaper or change movable blade), the lower thread being too short and not unwinding smoothly (adjust or change bobbin case spring), or the lower thread being too weak or too elastic (clean/check for dent in thread guide on the bobbin case, change lower thread).
