Dear sir,

I am using Atlas Copco Model GA122 air compressor. My problem now is, after I ON the compressor, when the air full, it does not cut-off properly. It try to cut-off and release air but cannot cut-off. It on & off many time then only finally it cut-off after many attempt. My friend ask me to check the vane valve. I want to get your recommendation . Pls help.

James, you need some help from Atlas Copco, I think. I have posted this in the hope that someone else with a similar compressor can post some assistance for you.

I also hope that you were able to get a copy of the manual.

Cheers,

Bill
