Balancing the buttonhole
On some kinds of fabrics, there may be a dif-
ference in the density of the stitches on the
right or the left side of the buttonhole.
This is easily adjusted by turning the balance
knob (1), in the center of the stitch length dial
to balance the density of the stitching.
A very slight turn of the dial will produce a
noticeable change.
• If the stitches on the right side of the button-
hole (I) are too open, turn the balance dial
slightly to the right, until the density of the
stitches increases.
• If the stitches on the left side of the button-
hole (II) are too open, turn the balance slightly
to the left, until the density of the stitches
increases.
