I have an older version of this machine already, and when looking through manuals discovered there was a model that took an adapter for chain stitch. I was considering trying to covert my older one, but in the end I found this machine- and it's already set up for it.
Although SteveH hates this stuff, the machine was securely packed. I had to remove some packing material to get to this point.
And the manual showing the adapter - I've managed to get two of these so far . . . one deliberaly and the other showed up a "lot" of misc stuff.
