I've been reading posts on compressors here for months now, finally got one last week. Thanks to everybody, especially oldred, for all the advice. :thumbup: I bought a used 6 year old QT-5 5 hp, 60 gal. 2 stage Quincy for $600. Seemed like a snooze you lose deal, so I grabbed it quick. Probably OK, but I'm realizing it wasn't maintained at all. I'm wondering about things I should check before cranking it up (haven't seen it run yet), any advice is appreciated.
The oil looks like it was never changed, factory sealant on the drain plug still had flawless paint. Rough guess by what he said, it probably has at 2000 hours (+/- ???)on it. Any damage from that you think? A few tiny metal flakes in the oil when I drained it, didn't seem bad though.
The pressure gauge is sprung, reads 50 psi with tank empty. I got a new one (Acme), but am a little concerned at what would cause that?? Glancing at the pressure shutoff adjustment and comparing it to a new one here, looks like the nut is at the same depth. I figured, assuming the new gauge is accurate, I'll see as it pumps up - should cut out at 175 psi, right? And if he messed with it (have read your warnings on that oldred), release valves should go. Release valves seem to move OK.
He said he drained the tank every day, he used it for paintball tanks and needed dry air. Banged on the bottom, from some from advice here, sounded solid.
Still need to wire it up, motor is a 21 amp Baldor, so 30 amp 220 with 10 ga. wire (about 30 ft.) should be good, right?
Anything else I should check? Will get a new air filter too. The guy seemed real nice, said he'd take it back if there was any problem. He replaced with a super high CFM tankless thing that suits paintball better.
