I got a Craftsman model 919.177550 air compressor from a friend, he lost the manual for it. How can I get another manual? I called Sears part direct and was told they don't have them if the compressor is over 5 years old. Also, if I can't get the manual, can you tell me how big a breaker I should have it on? It has a 5hp 2cyl engine that requires 220V and has a 30 gal tank. Any info you can give me on this compressor (including any normal maintenence that needs to be done to it) would be greatly appreciated.
