Balancing Thread Tension
Correct tension:
The ideal straight stitch has threads locked between
two layers of fabric.
For an ideal zigzag stitch, the bobbin thread does not
show on the right side of the fabric, and the needle
thread shows slightly on the wrong side of the fabric.
1 Needle Thread
2 Right Side of the Fabric
3Wrong Side of the Fabric
4 Bobbin Thread
Adjusting the tension
Tension adjustment may be needed depending on the
sewing materials, layers of fabric and other sewing
conditions.
Turn the tension control dial to set the desired number
at the setting mark.
Consult information on the LCD screen for the
recommended tension setting.
