I bought my machine used and have never had the correct manual for it. I am needing to do work on my tool changer but do not have the manual with my Yasnac MX3. Furthermore, I can not find the serial number for my machine. The tech I have had out seems to think that this particular machine came straight over from Japan and for some reason never had a serial number. Does this sound correct? Any help would be greatly appreciated.

Thank you
