Troubleshooting

  1. Stitch is too loose.
    1. Check the thread tension.
    2. Check the sharpness of the feed dog and throat plate teeth.
  2. The needles keep breaking.
    1. Check the looper and needle alignment.
    2. Check the needle alignment to the throat plate and presser foot needle guide.
  3. The thread keeps breaking.
    1. Replace needle.
    2. Is the thread unrolling easily from the cone?
    3. Check the thread tension.
    4. Check the thread guides and make sure they are clean.
    5. Check timing procedures listed in item #2.
  4. The machine is skipping stitches or does not make a thread chain at the end of the bag.
    1. Check the thread tension.
    2. Make sure the thread guides are clean and that thread can easily pass through them.
    3. Is the thread unrolling from the cone easily?
    4. Check the teeth on the feed dog and the throat plate. Replace them if they are dull.
    5. Check if the needle is bent, loose, or misaligned (replace it).
    6. Check if the looper is loose, worn or needs to be reset.
    7. Make sure the machine is properly threaded.
  5. See our tips page for other suggestions. Approximately one-third of all machines received in our shop for service have the needle inserted incorrectly. Please see needle replacement for correct installation. A new needle in the correct direction will solve many sewing problems.
