But the schematics helped me figure out what screws might be loose.

However they do not offer a repair manual or tell you the specific placement of the loopers for timing. You can get schematic pictures of all the interior parts, and order any possible part by going to the sears parts website and searching for your model of sewing machine or serger. After I fixed my machine I completed one project and it seemed to work fine, but the next day my needle broke again, so it still needs a little fine tuning. So I am going to explain what I did so there is at least something on the internet for people to look at, but I wasn't even completely successful. But in my case I figured it was worth it to see if I could get it working. Fiddling around with things on your own could make things worse so that if you do bring the machine in to get repaired it could cost more. I am warning you that I am not an expert, this is my first time ever trying to fix a serger, and I had very little information to go off of. Maybe the sewing machine manufacturers are trying to keep the relevant information secret so you feel compelled to buy a new machine when yours breaks. Especially if you have machines that only cost around $100-$200. Considering that the local repair shops charge $100, it becomes very pricy to get your machine(s) serviced every year as recommended.
So I think there is some kind of conspiracy going on.

However it did give me some good hints that let me figure out how to set the timing. Plus it isn't really generic, it is basically some notes for some various older Singer sergers. I did get a "Generic Serger Manual Service and Repair" for x-mas but it is basically a photo copy of some info from the 80's and is missing some relevant pages. I assume they must learn the ropes through some sort of apprenticeship. I don't really know how a person becomes a sewing machine technician. There also seems to be a lack of books, or even classes on sewing machine/serger repair. I did get some help from the nice people in the alt.sewing google group but basically there is no information on the web on how to repair a serger. So I went on the internet and searched and searched for information on how to repair and set the timing on a serger.
