I found nothing on this serger. This might be helpful

My guess is that it is the same as some other serger, with just a different name on it.
In the same situation with a sewing machine, you look for a sewing machine that appears to be the same. You go to the manual sites and look at pictures until you find it. I would start looking at babylock sergers, if they make them.
Hopefully, someone else will have a better idea.
