Why does the thread keep breaking on my SWF MAN-12 Sewing Machine?
- A
  Ashley OlsenAug 19, 2025
  If your SWF Sewing Machine experiences thread breaks, the issue might stem from several causes. The stitch may be too small or dense for the thread, requiring you to re-punch the design. Frequent breaks in the same spot suggest a need to re-punch after checking the design. An inadequate needle size for the thread calls for a needle change suitable for the thread type. A damaged needle (bent, dented, or worn) also necessitates a needle change. Incorrect needle installation (height, direction, etc.) requires re-installation. Lastly, a dirty needle (adhesive, etc.) suggests cleaning or changing both the needle and hook.

Why is the stitch quality bad on my SWF MAN-12?
- K
  Krystal RogersAug 25, 2025
  If your SWF Sewing Machine is producing bad stitch quality, it could be due to several factors. The tape data might be bad, requiring correction. The tension on the X-Y belt may be inadequate, so you should adjust the tension. There might be foreign substances in the X-Y rail, so you should clean them. The X/Y drivers might have failed, so you should replace them. Finally, a heavy load on the frame could be the cause, so try reducing the speed of main shaft rotation.

How to fix poor stitch tension on my SWF MAN-12 Sewing Machine?
- N
  Nicole JonesAug 26, 2025
  If your SWF Sewing Machine is experiencing poor stitch tension, it could be due to several reasons: Weak upper thread tension, which requires adjustment. Uneven upper thread tension due to foreign substances, necessitating cleaning of the main and sub tension adjusters in the thread tension adjusting plate. Weak lower thread tension, which requires adjustment. Uneven lower thread tension, so clean the bobbin case and check tension on the bobbin spring. The thread thickness might be the cause, so change to a quality thread. Poor timing of needle and hook, requiring adjustment. Insufficient oil in hook, so oil the raceway of hook.

What causes needle breaks on my SWF MAN-12?
- G
  Gabriel CarrollAug 28, 2025
  If you're experiencing needle breaks with your SWF Sewing Machine, it could be due to a bent needle (change the needle), a bad quality needle, a worn or bent needle tip, or an inadequate needle size. The needle might be touching the hook point, so space the needle and the hook point. It could also be due to incorrect installation of the needle, so correct the installation. Finally, the needle might be touching the needle hole on the needle plate, so check if the needle plate is unscrewed and adjust the position of the needle bar.

Why is my SWF Sewing Machine failing to operate?
- A
  Andrew SullivanAug 30, 2025
  If your SWF Sewing Machine is experiencing operation failure, it could be due to loose belt tension or belt damage, so adjust the belt tension or change the belt. It may also be due to a power failure or short-circuit of the fuse, so change the fuse in the power socket.

Why is the stop position incorrect on my SWF MAN-12 Sewing Machine?
- D
  donald21Sep 1, 2025
  If your SWF Sewing Machine has an incorrect stop position, it may be due to loose tension on the main driver belt, so change the belt. It could also be caused by an incorrect position of the encoder or a bad encoder, so adjust the position or change the encoder.
