I can't figure out how to use the feather stitch on my sewing machine..?

Question:I lost the instruction manual for my Nicchi Omega sewing machine and can't figure out how to use the feather stitch. The left nozzle has the zig zag, then the needle placement, then the button hole steps. The second nozzle has A-H and B is the feather stitch, but when I put it on B I still don't get a feather stitch. If anyone knows what I am talking about, I would greatly appreciate your assistance. Thank you!

You can't go wrong by contacting Nicchi especially since your machine is an Omega model and you haven't related what Omega model? What year? What is the serial number?
