Why is trimming failing on my SWF MAN-12 Sewing Machine?
If your SWF Sewing Machine is experiencing trimming failure, it could be due to poor connection or bad quality of the trimming solenoid, so check and change the solenoid and solenoid connection. It may also be due to a bad connection, so check the connector. Another cause could be damaged X, Y driver TR, so change the X, Y driver.
What causes short upper thread after trimming on my SWF Sewing Machine?
If your SWF Sewing Machine has a short upper thread after trimming due to separation failure, it could be because the movable blade is too fast or too slow to separate the upper thread, so adjust the insert angle of the movable blade (295 ). It might also be due to an incorrect position of the picker, so adjust the picker position. Another cause could be picker failure, so check and change the X, Y drivers.

If your SWF Sewing Machine experiences a thread break before trimming, it could be because the upper thread is too short (check main and sub tension adjuster) or there is a dent or damage of movable blade (adjust upper thread tension, remove dent using whetstone or sandpaper, or change movable blade). It may also be because the lower thread is too short, doesn't unwind smoothly, or is too weak or too elastic (adjust or change bobbin case spring, or change lower thread).
