Does anyone happen to have any pointers for a newbie on successfully threading a Janome 634D serger? I just bought a used one and seem to be having some trouble getting it properly threaded (surprise, I've never used an overlock machine before). Right after I thread it, using the manual and diagram on the machine for guidance, it will stitch, but the chain is very hard to pull after I'm done stitching and raise the presser foot. The next time I try to stitch, nothing takes; when I open it up the lower looper has come unthreaded, and the thread end is lying in the bottom of the case. :( I'm following the threading order mentioned in the manual; lower looper, then upper looper, then needles.
Any thoughts would be greatly appreciated!
Thanks! Sandra codemeister
