I have inherited an older (1987) Ingersol Rand Model 5E6V Air Compressor. 60 Gal tank, 5 hp, 240 volt/15 amp motor. Had not been used for 3-4 years, was missing the motor pulley, belt and belt guard.........managed to get the correct size pulley and then a belt to fit (belt guard is no longer available..but not that big of a deal), changed the oil...anyway got the system running.....my question is how is the unloader supposed to work...(did manager to down load a copy of the owners manaul but no info in there on how to set and/or adjust the unloader valve)......at first the unloader was letting air out all the time it was running and after it automatically shuts off when it reaches 125 lbs. pressure. Did not seem right..so I adjusted it so it only let the air out after the compressor shuts off at 125 lbs. pressure point.....is there point where it should stop letting air out? Right now it seems to be letting air escape all the time the compressor is not running, no matter if the main switch is in the off or on position. And how long is the unloader supposed to let the air out after the pump/motor automatically shuts off (at 125 lbs.)?
Have included a photo of the switch and the unloader valve thing.....
Sorry for all the questions, just want to make sure I have it set up correctly......do not want to damage anything..........
Any help would be appreciated
