Atlas Copco Model GA122 cannot cut-off and discharge air properly once the air full

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.

check your pressure switch. if it works properly, check the solenoid valve (that the pressure switch runs) if it's stuck. If both of them works as they should, you have to check the intake/exhaust valve./kaeser mechanic in scandinavia
