When stitching Is 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. (See
page 24)
When adjusting the tension on the
bobbin case, make slight adjustments
with a screwdriver. (See page 24)
