Start sewing – front bartack, lockstitch. Machine will
automatically stop when buttonhole is completed.
Sewing Additional Buttonholes
To sew another buttonhole the same size - raise foot,
move fabric, lower foot and sew.
Reset Buttonhole Size
To sew a buttonhole a different size (or to adjust stitch
length), reset the machine by pressing "ENTER" key or
reselect buttonhole. Sew new buttonhole size using same
method.
Cutting Open Buttonhole
Place a pin just inside the bartack at each end to prevent
accidentally cutting bartacks. Cut buttonhole open with
the seam ripper.
Troubleshooting Tip
If there is a difference in stitch length (density) between
the right and left sides of the buttonhole, use the fine
adjustment screw. See page 19.
