[AT] Air compressor failure

[Stuart Harner]

I had that exact same compressor until August when it blew a pin hole in 
the bottom of the tank and started leaking. It was 15 years old and I 
thought I had been good about keeping it drained but it still rusted 
through. It never had any problem reaching the 135 PSI.

There should be a dip stick on a plastic fill plug just to the right 
side of the compressor. It just pulls straight out. If it were low on 
oil I would think it would be making a racket, but it should be checked 
anyway. Also there is an intake air filter at the top of the compressor, 
check to make sure it is not plugged.

In the picture it has the air outlet valve open. Have you tried running 
it with that valve closed? A fault in the air line downstream somewhere 
might be leaking off just enough air that it can't quite trigger the 
cut-off.

Of course the cut-off itself could be faulty but one would think it 
would continue to build pressure until it popped off the safety valve. I 
would get some air into the tank and then manually pull the safety valve 
open to make sure it is functioning. With the compressor not running the 
safety valve should re-seat itself when the pressure drops low enough.

My old one is in the storage shed and I am sure I can find the manual if 
you need more information.
