Stitch length
It can be adjusted while sewing.
The stitch length is infinitely variable from 0.7 to 4 mm.
Most overlock work is done with a basic setting of 2.5
mm.
For roll hemming or narrow overlocking, it is best to set
the dial at “0.7 to 1.5”.
For blind stitch which requires the “use of separate-
ly-available presser foot”, set the dial at “4”.

attempt to cut anything other than fabric and
