[HELP] Can anyone help me with info about this compressor

[Dan Boy]

Hi, I recently bought this compressor.  It works great but I would like to know more about it including how to adjust it if I need to.

The manufacturers have gone out of business so I can't contact them anymore.

Any information would be great and if anyone has a manual even better!

Thanks, Daniel.
