Whenstitchingis unsatisfactory as in
figures 2 and 3, adjust the upper
thread tension. Lower thread tension
requires adjustment less frequently
than the upper thread tension.
When stitch is satisfactory, as in figure
1 and seam is badly puckered, the
cause may be tight tensions and both
upper and lower may be adjusted.
When adjusting the tension on the
bobbin case, make slight adjustments
with a screwdriver. ISee page 38)
It is necessary to reduce the upper
thread tension somewhat when doing
decorative stitching. As the stitch
width is increased, the tension should
be decreased.
