Setting
Buttonholer stitch density balance
Check
Under normal working, the buttonholer retreats, makes the bar tack, advances, makes the
other bar tack and stops and both legs/columns of the buttonhole should have equal density.
Adjustment
1. First check so the Buttonhole's Forward and reverse adjustment is correct.
2. Sew a button hole.
-The Left and right sides of buttonhole must have an equal number of stitches
-The distance between the two inner perforations should be 0,5 to 1,0 mm.
Buttonhole forward Leg/coluom balancing:
1. Loosen the nut (a).
2. Turn the eccentric screw (b) to reach the correct density of stitches.
3. Tighten the nut (a).
Buttonhole reverse balancing:
NOTE ! This is a enduser adjustment, done with the stitch lenght selector so the reverse side is
equal to the forward side.
