    Why does the thread keep breaking on my JUKI DU-1481-7?

      If the thread is breaking on your JUKI Sewing Machine, make sure the machine head is threaded correctly. A bent or broken needle tip can also cause this, so replace the needle if necessary. Also, check the needle insertion position and re-insert it properly if needed. The needle thread tension or bobbin thread tension might be too high; decrease them accordingly. Finally, the operating quantity of the thread take-up spring may be too large, so adjust it appropriately.

    How to prevent slip-off of thread or stitch skipping at the beginning of sewing with JUKI DU-1481-7?

      If you're experiencing slip-off of thread or stitch skipping at the beginning of sewing with your JUKI Sewing Machine, ensure the needle is correctly inserted and pushed up as far as it can go. If the needle is bent, replace it. Make sure the threading direction is correct by following the proper threading procedure. The timing between the needle and the hook might be off, so adjust it appropriately. If the length of needle thread remaining at the needle is too short, decrease the thread tension provided by tension controller No.1. Finally, if the thread take-up lever is drawing thread out of the needle eyelet, readjust the upper stop position of the needle.

      If your JUKI Sewing Machine needle is breaking, it could be due to several reasons. First, ensure the needle is correctly inserted. If the needle is bent, replace it. Other potential causes include incorrect feed dog timing, incorrect timing between the needle and hook, incorrect needle bar lower dead point, or incorrect clearance between the needle and the hook. Adjust these components as needed.

    What to do if JUKI DU-1481-7 Sewing Machine has thread trimming failure?

      If your JUKI Sewing Machine is failing to trim the thread, it might be due to several reasons. The height of the moving knife and hook might not match, so readjust the installation position of the moving knife. Also, check the pressure and position of the moving knife and counter knife. If the needle is not inserted correctly, re-insert it. If the moving knife and counter knife are flawed or worn out, replace them. The timing of the thread trimming cam might be incorrect, so adjust it accordingly. Finally, the stroke of the tension releaser might be too small, so readjust it.

    Why is my JUKI Sewing Machine sewing perfor­ mance failure?

      If you're experiencing sewing performance failure with your JUKI Sewing Machine, it could be due to incorrect needle or bobbin thread tensions. Adjust these tensions appropriately. The tension of the thread take-up spring might also be inadequate, so adjust it accordingly. Additionally, the clearance between the inner hook holder and the hook may not be adequate, so adjust that as well.

    What causes the length of needle thread remaining at the needle (on the material) to be too short on JUKI DU-1481-7 Sewing Machine?
    • A
      Alexander ObrienSep 1, 2025
      If the length of needle thread remaining at the needle on the material is too short with your JUKI Sewing Machine, it could be due to several reasons. The thread trimming timing might not be correct, so adjust it appropriately. The opening of the thread nipper bar might be too small, so increase it. The thread tension provided by tension controller No.1 might be too strong, so decrease it. Finally, the operating quantity of the thread take-up spring might be too large, so adjust it appropriately.
