FAQs & Troubleshooting

How do I manually thread my machine?

  • Be sure to thread the machine properly. Incorrect threading can cause the thread to tangle and break the needle, leading to injury.
  • When using accessories not included with this machine, attach the accessory to the machine after threading the machine.
  • Never use the thread of No. 20 or lower.
  • Before manually threading the machine, be sure Presser foot/Needle exchange key to press in the LCD, otherwise injuries may occur if the "Start/Stop" button or any other button is pressed and the machine starts sewing.
 

Automatic threading cannot be used when using the wing needle, the twin needle, or special thread with a thickness of 130/20 or thicker. In these cases, thread the needle as described below.

  2. Turn the handwheel so that the line on the machine is aligned with the line on the handwheel.

    If the line on the machine is not aligned with the line on the handwheel, the sewing machine cannot be threaded. Check that the line on the handwheel is facing up as shown in the illustration above.

     
  3. Press Presser foot/Needle exchange key at the lower right of the LCD screen.
    The entire screen becomes white, and all keys and operation buttons are locked.

     
  4. Raise the presser foot lever.

    If the presser foot is not raised, the sewing machine cannot be threaded correctly.

     
  5. Pivot the spool pin so that it angles upward.
    Set the thread spool on the spool pin so that the thread unwinds from the front of the spool.

  6. Push the spool cap onto the spool pin as far as possible, then return the spool pin to its original position.
    • If the thread spool and/or spool cap are set incorrectly, the thread may tangle on the spool pin and cause the needle to break.
    • Use the spool cap (large, medium, or small) that is closest in size to the thread spool. If a spool cap smaller than the thread spool is used, the thread may become caught in the slit on the end of the spool and cause the needle to break.
    • When sewing with fine, cross-wound thread, use the small spool cap, and leave a small space between the cap and the thread spool.
