FAQs & Troubleshooting

Upper Threading (Threading the upper thread)

 

  1. Turn on the sewing machine.

     

  2. Raise the presser foot lever to raise the presser foot.

     

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

     
  3. Press ("Needle Position" button) once or twice to raise the needle.

    The needle is correctly raised when the mark on the handwheel is at the top, as shown below.
    Check the handwheel and, if this mark is not at this position, press ("Needle Position" button) until it is.

     

  4. Open the top cover.

     

  5. Remove the spool cap that is inserted onto the spool pin.

     

  6. Place the spool of thread onto the spool pin.

    Slide the spool onto the pin so that the spool is horizontal and the thread unwinds to the front at the bottom.

     

    If the spool or the spool cap is not positioned correctly, the thread may become tangled around the spool pin and the needle may break.

     
  7. Slide the spool cap onto the spool pin.

    Slide the spool cap as far as possible to the right, as shown, with the rounded side on the left.

     

  8. While holding the thread lightly with your right hand, pull the thread with your left hand, and then pass the thread behind the thread guide cover and to the front.

     

  9. Pass the thread under the thread guide plate, and then pull it up.

     

  10. While using your right hand to lightly hold the thread passed under the thread guide plate, pass the thread through the thread path in the order shown below.

     

    • If the presser foot has been lowered and the shutter is closed, the machine cannot be threaded.
      Be sure to raise the presser foot and open the shutter before threading the machine.
      In addition, before removing the upper thread, be sure to raise the presser foot and open the shutter.
       
    • This machine is equipped with a window that allows you to check the position of the take-up lever.
      Look through this window and check that the thread is correctly fed through the take-up lever.

     
  11. Pass the thread behind the needle bar thread guide.

    The thread can easily be passed behind the needle bar thread guide by holding the thread in your left hand, then feeding the thread with your right hand, as shown.
