Not totally familiar with that serger, but I just shortened the stitch a little, the odds are I probably didn't have to, the serging will keep it from fraying so don't need keep the stitches to tiny.
I used the Imagine from Babylock. four thread 1/4" seam just over a 2 on stitch length.
I have a lot of orange serger thread so I am not worried about thread consumption.
