Forterra Air compressor purge normal condition

[scott12441]

Same guy different question. Wondering the normal operating sound of the air compressor. When you shut the tractor off should it release pressure and allow water to drain? Recently it started hissing when sitting running, I shut down and noticed the relieve valve on bottom of tank. My thought is the valve is designed to release moisture when the tractor is shut down. I played with it a bit and now when I power the tractor down you can hear the air drain. I am thinking it is now working properly and wasn't before. Thoughts? Thanks Zetors

They shouldn't be leaking. It has a spring on it which seals the pin. It's either broken or dirty.

On my 140 HSX the compressor comes on after the engine is started and top up the tank after that it releases air where the valve is at the steps then when you use the splitters air comes out of the tank and compressor tops up the tank again .

If you want to pump a tyre, you need to pull the ring on the bottom of the tank and release air out of the valve so the compressor cuts in and you have pressure in the hose.
