Bobbin Placement in Case
Adjusting Bobbin Tension:
• Adjust the tension knob until the top of the plastic knob is ush with the top of
the chrome post.
• Follow the chart below to set the tension knob for the type of thread you are
using. Poly threads require nearly twice the amount of tension as rayon.
• After setting the upper tension knobs, stitch a (1 inch) capital letter “I”. View the
underside of the garment to determine if the bobbin tension needs adjusting.
