Thread tension
The basic setting

adjustment wheel is in line with the marking A
• the tension does not need adjusting for normal
sewing work
• for special sewing work, the tension can be
adjusted to suit the fabric
To reduce the tension
turn to between 3 and 1
To increase the tension
turn to between 5 and 10
The tension is factory set for the best results.

If other sewing or embroidery threads are used,
the tension may need adjusting to suit the fabric
and chosen stitch.
