STITCH PATTERN/BUTTONHOLE DIAL
This dial is used for selecting the stitch pattern, for adjust­
ing the zigzag width and for sewing the easy, built-in, four-
step buttonhole.
• Stitch Pattern Selector:
Including straight and zigzag stitches, 6 kinds of the stitch
patterns, as shown on the dial, can be selected. Turn this
dial in any direction and the pattern of the stitch chosen is
indicated by the white guide mark above the dial.

Note: When sewing with the dial at the mark, the
stitch length dial should be at the mark.
• Zigzag Width Control: ,
At the straight stitch symbol ( j ), the needle does not
swing and, therefore, a straight stitch seam is sewn. With
the dial at the narrow zigzag symbol ( | ), the needle takes
a narrow swing resulting in a narrow column of stitching.
At the widest zigzag symbol ( ^ j, the needle takes a large
swing resulting in a wide column of stitches. The dial may
be set at any position desired between the straight stitch
and the widest zigzag positions for a variety of widths.
Note: When sewing with twin needle, the dial should be
set in the white zone.
• Buttonhole Control:
When set at the first buttonhole symbol (step 1),
your machine sews, forward, the left side of the
buttonhole. With the dial at the next buttonhole
symbol (2—4|, your machine feeds the fabric for
bartacking the buttonhole ends and, set at the
third buttonhole symbol (3), it feeds the fabric in
reverse to sew the right side of the buttonhole.
RELATING STITCH LENGTH TO STITCH
WIDTH
When the stitch width dial is set at one particular
width (such as the widest zigzag) the stitch length
dial will then determine how closely the stitches
are sewn together. At length 0, the fabric does not
move so that the stitches are formed one on top of
the other, as is used when sewing on buttons. At
the symbol Q or near 0, the fabric is fed through
slowly resulting in a dense column of stitches
known as a satin stitch. At length 5, a very long,
open zigzag is sewn.
