  Poor stitch formation on your JUKI Sewing Machine may be caused by a few issues. Check if the threads are correctly positioned between the tension dials, ensuring the thread is lying between the tension discs. Also, check if the thread has gotten caught; raise the presser foot and pull the thread. Finally, the machine may be incorrectly threaded, so check the threading path of each thread.

  To resolve issues with threading the upper and lower loopers on your JUKI Sewing Machine: Raise the threading changeover lever and turn the handwheel to fix it. Insert the thread into the threading hole by 1 to 2 cm. Slack the thread before the threading hole. Remove the thread from the location where it has been caught. Thread the loopers by means of the looper threader supplied in the accessory bag to remove the lint in the pipe.

  Seams puckering on your JUKI Sewing Machine can result from a needle thread tension that is too tight, so reduce the needle thread tension. It can also happen if the differential feed is set incorrectly; adjust the differential feed to 0.7 - N.
