    Thread picker is a device that is used to hold the thread when beginning to sew or when trimming the thread.

    The thread picker can only be moved within a certain range. Do not pull it with extreme force.

  • Oiling the machine

    After removing the bobbin case, apply oil to the machine. The race should be oiled.

Installing the bobbin

  • This embroidery machine is not equipped with a bobbin-winder. Use pre-wound (L type) bobbins.
  • The optional bobbin winder (stand-alone type) and optional metal bobbins can also be used.


 

  1. Insert the bobbin into the bobbin case.

    Check that the thread winds off the bobbin clockwise as shown in the illustration. If the bobbin is installed with the thread winding off in the opposite direction, the embroidery will not be sewn correctly.




     
  2. Pass the thread through the thread slit and under the tension-adjusting spring.

  3. Pull the thread about 50 mm (2 inches) through the opening in the tensionadjusting spring.
    For adjusting the tension of the bobbin thread, refer to “How do I adjust the tension of the bobbin thread ?”.
