It being labeled custom vac, that plastic bottle could contain something that was being vacuumed, aka bodily fluids. Be careful.

Ouch, I didn't see that coming!  I was going to use the Jun-Air hour meter until I saw it was 50Hz, the compressor is 120VAC 60Hz.  I installed the compressor today, quite a difference in noise level compared to the Thomas compressor, neighbors on the drivers side will appreciate that.  I'll use it next week and then change the oil.  Looks like the top is removed and the oil poured out, I suppose you could suck it out?
