Altering the stitch length
stitch length adjustments affect both buttonhole beads (spacing between
█
the stitches)
reprogram the buttonhole length after changing the stitch length
█
Balance for automatic and manual buttonholes
Any balance alterations to the manual and auto-length buttonholes affect both
beads identically because they are sewn in the same direction.
If a buttonhole is sewn at right angles to the
fabric edge/fold, we recommend the use of
the height compensating plates for buttonho-
les (available as optional accessory).
Place the plates from the back between fabric
and bottom of slide foot up to the thick part of
the fabric and push to front.
When all buttonholes have been sewn,
return balance to the normal setting!
