Thanks, Countryboy.....great to be here, also...
Big, the place I got my manual from has, naturally, gone out of business. However, if you want, email me your address, and I'll have my manual copied, and I'll be happy to send it to you.
Sorry, Nedly, no pictures of mine. It was origionally a pull type (trailer-mounted) compressor. I stripped it down, and mounted it on my service truck, so now it doesn't look anything like it did. If it is a Joy that you have, it should be easy to tell. They were proud of their name. Mine has name stamped into the radiator support, right above the grill, the seperator tank should have a plate with the build date, and mfg. name, and mine also has "Joy" tags everywhere they could think to put them. Most compressors have an ID. plate on them, and for the most part, at least the ones I've seen, for some strange reason, they are still intact.
I bought mine when I was just starting my road service business as a temporary kind of thing. I could pull it behind my first service truck, which was just a pickup. I figured when I built my big truck, I would get rid of it, and get something more modern, and smaller (joy airvane 125 weighs in at 3500 lbs). However, after running it my first winter, I couldn't bear to part with it. It's been 13 years now since I bought it, for $600, and I've probably only spent $500 on parts, ran it for countless hours, and it still runs like a swiss watch.
Most of the time when someone says "They don't build 'em like they used to!", I say, "Thank God they don't!" But in this case, never a truer word spoken.
Sorry for rambling on, but usually I don't have an audience that appreciates a great piece of equipment.
Have a wonderful day.:drinkup
