Cutting Width Adjustment
Fold the fabric in half to 3” x 6”.
Divide and mark the fabric into three equal sections along the folded
edge.
Thread the serger for a 4-thread overlock stitch. Fine tune the tensions
for a balanced overlock stitch (3-5).
Rotate the upper knife up. Adjust cutting width to 3. Rotate the upper
knife down into cutting position.
Serge to the first mark on the fabric, stopping when the knife edge
is on the mark.
Adjust cutting width to 2mm and serge to the second mark.
Adjust the cutting width to 1mm and serge to the end of the fabric.
Mark the cutting width settings on the sample.
Rotate the upper knife up. Return the cutting width to its normal setting,
2mm. Rotate the upper knife down into cutting position.
Compare the cutting width sample to the balanced 4-thread sample
to see how cutting width affects the balance of the overlock stitch.
