Trouble shooting

Any time you experience a problem when
sewing:
• Select correct type and weight of fabric in the Sewing
Advisor.
• Insert needle size and type as recommended on the
GraphicDisplay.
• Rethread the top and bobbin threads.
• Use different spool pin positions (vertical or horizontal).

sewing thread on top and bobbin for general sewing. For
decorative sewing we recommend embroidery thread on top
and bobbin thread on bobbin.

Sensor Buttonhole:
