Why are the fabric edges curling when using my JUKI MO-735?
- J
  Jeremy LopezAug 31, 2025
  If the fabric edges curl when using your JUKI Sewing Machine, it could be due to a few reasons. There might be too much fabric in the stitch, so try reducing the cutting width. Another possibility is that the thread tension is too tight, in which case you should reduce the thread tension. Lastly, check that the stitch selection lever is not set on roll hem; if it is, set it to overlock.

  If you're getting poor stitch formation with your JUKI Sewing Machine, make sure the threads are correctly positioned between the tension dials. Check if the thread is lying between the tension discs. Also, see if the thread has gotten caught and, if so, raise the presser foot and pull the thread. Finally, ensure the machine is correctly threaded by checking the threading path of each thread.

Why does the thread keep breaking on my JUKI Sewing Machine?
- J
  jamie39Aug 27, 2025
  If your JUKI Sewing Machine thread breaks, it might be due to several reasons. The thread tension could be too tight for the thread you're using, so try reducing the thread tension. Also, double-check that the machine is threaded correctly. Ensure the needles are correctly inserted fully into the needle clamp with the flat side to the back. Finally, make sure you're using the correct needles, specifically needle system 130/705H or JLx2.
