Hi all just got myself a nice little arrow 500,the question is do these things normally suck up heaps of air through the air system it just seems like the compressors running all the time.I know they have a spindel bearing oiler but that doesnt appear to be using much air, theres a couple of valves on top of the turret arm that appear to be always leaking ,anybody played with these before or found any other solutions before I start digging to deep Regards Greg.
