Balancing the Buttonhole
Stitch density on left and right sides of the buttonhole
may be balanced by adjusting the buttonhole balance
knob K. Use the buttonhole balance knob to obtain
similar stitch appearance on left and right sides of the
buttonhole. A very slight turn will produce a noticeable
density change.
To change the density on either side of your test but­
tonhole follow the procedure below. Before sewing on
your garment, be sure to make a test buttonhole on a
sample of your fabric to check that the stitch density
is similar on left and right sides of your buttonhole.
1. Make a test buttonhole with the balance knob in
neutral position (indicator line or dot directly
below ▼symbol on control panel).
2. If the stitches on the right side of the buttonhole
are too open, turn the balance knob from its neutral
position to the right to increase density of the side
stitching.
3. If the stitches on the left side of the buttonhole are
too open, turn the blance knob from its neutral
position to the left to increase density of the side
stitching.
After buttonhole stitching is completed, return bal­
ance knob to its neutral position (indicator line or dot
directly below ^symbol on control panel).
