Asada Piset 3SG service guide/manual

Hi,

I recently purchased an old threading machine, however it didn't come with any form of manual or service guide. I need one because section of the tool need replacing and it needs a bit of TLC, I was wondering if anyone could give me an idea of where I could possibly get one or even point me in the right direction.

Its a Piset 3SG machine (however Piset was taken over by Asada hence the name change)

Thanks for all your help.
