I have bartered for a blindstitch hemmer and it does not have a manual with it. it is a techsew BLST2. that is about all I know about it any help would be appreciated

Can you send a picture...I have a Kobe blinstitch...mine is very easy to thread...don't really need the manual...but I do know mine likes to be oiled regularly...all moving parts...
I have an old Rimoldi serger in the garage that is more complicated to thread...
If you attach a pic I can see if it is like mine..mine is sold under a bunch of different names..

I will upload tomorrow

Not sure if any of the suggestions on this site will help, but might be worth a try:
