GX CS4 Pressure Problem

I have had a CS4 for about a year and it has worked great, about 12 hrs on it. A month or so back I was filling a few guns and after the first one ( that filled fine ) I started another and everything looked and sounded fine but there was no pressure building? After turning it off and on several times it started building pressure fine? So now this has happened about 4 times. Sometimes just trying to fill a gun and sometimes trying to fill a second? Anyone experienced anything like this?

Thanks,
Chuck

Sounds like dirty check valve. Inspect and clean check valve under burst disk on top of compressor.

A friend recently purchased a CS4-i and had similar problems right out of the box. GX advised him to test the compressor at 12 volts. He did, and it worked perfectly. The culprit was an out-of-spec power supply. It could be that, after a year, your power supply is failing. Try it at 12 volts.

I've had my CS4-I for less than 6 months. I had this same issue, no pressure. So, I followed this advice and it solved my problem. I couldn't believe how dirty the check valve was under the burst disc being less than 6 months old. Thank you.
