The stitch length is adjustable with the stitch dial which is calibrated in
mm.
1. Rotate stitch dial

2. Set a desired length to the feed regulator stop pin on the machine
arm.

when the stitch length is set to "0".
Raise stopper

control lever at a higher position, and a fi ner stitch will be produced
in the normal feed.

1. Manually rotate the handwheel until it is positioned as illustrated.
2. Loosen looper setscrew
