GX CS4 Pressure Problem

[Trampus99]

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.

Thanks I will try that!

I have a parts diagram but not parts list, where is the check valve located?

Under the burst disc..

Is this equivalent to the check valve in the cs2 that is on the bottom of that machine? Just received my cs4 and I know the one on the cs2 requires periodic cleaning.

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 saw a video and it shows the burst disc on top next to the tank cap on the cs4 with separate inverter?

Parts 69-71 in your diagram.
