I will be using my CS4 to fill a 40mim bottle. I was wondering do you run 15 minutes with a 10 min cool down? Or what is the recommended way to run these for large fills?
GX CS4 cycle on/off times?

These have a duty cycle of 5hrs. If the water temp is consistent, there is no reason to stop and cool down that often. You'll want to open the bleed valve to remove water and how often you do that will all depend on your humidity, and if you're using an external filter or not.

Yea I’m using an external filter. I’ll have to experiment with bleed valve. The room is climate controlled so hopefully humidity is minimal.

Open and close it while it's running as well. You don't want to shut off the compressor and restart with it under pressure. Plus with it running, it'll help clear the internal filter.

I run my for a max of 30 minutes and cool down for 10 minutes after. I don’t fill again until the next day or later. I bleed every 5 minutes even with an external filter.

I don't run mine any more than 12 hours at a time. It doesn't get hot. I just twist the grease screw about every 4 hours or so. My CS4 I, only runs long enough to fill airguns but the external power source version fills tanks and gets used. No problems and many hours. Great compressors. It had over 30 hours on it before I got the hour meter which shows 45 hours now. So around 70 hours with only one maintenance cycle ( nothing was replaced) of taking the thing apart to see how it was built back during the 30 hours prior to the hour meter being put on it.

The pressure gauge has 2 needles for setting your auto shutoff off, first one is main, second one is just incase the 1st doesn't shut it off.
Compressor stops when your set pressure is hit, but water pump will continue to run to cool compressor down.
There will be pressure in the line until you bleed it.

That’s where my question is stemming from, I always read that before shutting down the compressor bleed the line so there’s no pressure on the pump while it’s stopping. It must not be an issue because many pumps have thermal or pressure shutdowns.

The cs4 does have a thermal type sensor on the cylinder head that will shut the compressor down if it were to start to over heat (pump failure for example)
The issue isn't stopping with pressure... it's restarting with pressure in the line/compressor. That's a large strain on the motor and gears to restart with pressure that could easily be 2000 plus PSI.

Yes the bleed screw is left open. It can be closed but you would have to remember to open it every time you go to use the compressor again so the compressor isn't starting with it closed as that's not good for the thing.
