Buttonhole Fine Adjustment

If the stitching on the two sides of the buttonhole do not appear
uniform, the following adjustments can be made.

1. Set the Stitch Length Dial at “F-1.5” and stitch the right side of

the buttonhole on a scrap of fabric while observing how the
material is fed.

2. If the right side of the buttonhole is too coarse or fine, adjust the

feeding of the material with the Stitch Length Dial.

3. After obtaining a satisfactory feeding on the right side, stitch the

left side of the buttonhole and observe the feeding.

4. If the left side is too coarse or fine compared to the right side,

adjust the buttonhole fine adjustment screw as described below.

If the left side is too coarse, turn the screw with the enclosed
large screwdriver in the – direction.
If the left side is too fine, turn the screw with the enclosed large
screwdriver in the + direction.

This adjustment allows both sides of the buttonhole to appear
uniform.
