1.1. Winding a bobbin (video)

The bobbin winder pin is located either on the top of the machine or on its side.

Winding a bobbin

  • Insert the bobbin into the bobbin winder pin (1).
  • Lead the thread as shown in the illustration, check that the thread goes through all the guides and between the tension discs.
  • Wrap the thread a few times tightly around the bobbin (2).
  • Press the lock lever (3) against the bobbin and pull the thread end onto the cutter (4).
  • You can wind a bobbin at the same time when sewing OR separately without any fabric, in which case:
  • Remove the bobbin from the bobbin case and the thread from the needle eye, manually lifting up the presser foot.
  • The winding stops automatically when the bobbin is full.

  • Release the small, hinged latch (4) to insert the bobbin case into the shuttle.
  • Make sure the bobbin is locked in place.
