There is a URL to a compressor by Alltrade Tools in this thread.

If that URL isn’t the manual you want, the only other Alltrade compressor I can find is here:

http://www.alltradetools.com/catalog/19-481214-5-gallon-twin-tank-compressor-with-air-hose.html

Maybe visit this page, get the contact info for Alltrade and give them a shout?
