When you first get the compressor are you supposed to turn the grease dial prior to use or after 5-6 hours?

CS4i issue
- Thread starter SakoSierra
- Start date
I will say this, for anyone on the fence, it seems to run straight through as long as I am periodically checking the moisture bleed valve and adding grease when needed.
The manufacturer said it could be tripping the overheat protection and also said it could be possible air bubbles in the coolant system. I might try to drain and refill but for now it’s working pretty good. This is a 9L bottle I am filling so I get that it can be taxing on a small unit like this.

Fits perfectly on a amzon rectangle dolly. Have 8 hours on it and it’s cooling has been upgraded also.

The check valve on top could also need cleaning out and be sure the spring is in correctly.
Loose wires to the board can do it as well

I just bought the CS4i. This doesn't give me the warm and fuzzy feeling. It did however fill both my rifles from 0-250Bar way faster than my CS2. No random shutoffs tho. So that's a plus...Guess ill be looking out for it now.

My car manufacturer claims I can go 15000 mi between oil changes, would never exceed 5000 even if it were still under warranty.

I pulled the cover off my CS4I (second one received) and checked all the connections to make sure everything was tight. Couldn't find anything that was loose. Turned the compressor on and jiggled it around to look for air bubbles, didn't find any. Put the cover back on and tried a minor top off of my tank from 4000PSI to 4350PSI. Pump shut off three minutes later. Water temp 89F. Turned the pump back on and five minutes later it turned off again. Water temp 93F. Finally reached 4350PSI 25 minutes later, water temp 111F. Total shutoffs: five.
Searching the net, I've seen some owners who have tried disconnecting the temperature sensor. OK, it would make sense to see if that's the problem. Can someone help me out and tell me where it's located? If that doesn't work, I'm out of ideas. Just can't imagine another return to Amazon. What a PITA.

It's the part that is attached to the top of the cylinder head with a Phillips screw.
Follow the wire to where it's going to either be plugged into a harness or directly into the board. Just unplug it.

Just a question here...
Have you let the compressor just sit for any amount of time when it turned off to see if it auto kicks back on after a cooling session?
Wasn't this a feature of the compressor?
Yes, I realize this seems like a premature shut off considering the low temp but just curious.

Leaning toward one of these. Guessing not a question that probably can be realistically answered here but how prevalent do you guys think this shut off bug is ? Hopefully people know people who know other people with these compressors. lol. Otherwise unfortunately I guess this question will only reach a very small sample.

Have you contacted GX directly? I hear they only communicate by e mail. Please keep us posted on this. Planning to buy one soon , this certainly creates doubts especially as this is your 2nd one. Thanks for posting.

With some experience in retail and service ownership I learned that word of mouth is a powerful thing. You are less likely to hear feedback from a satisfied customer. They may tell a few family members and friends about the great new thing they got.
But a guy that got a bad deal or defective item will stand on top of a mountain and scream so the whole World can hear.

On mine, after experiencing the early shut downs I pulled off the cover and took a bunch of temperatures on the piston bore, head, coolant fill cap, radiator, and motor housing during a 43 minute compressor run. I found out that these run very cool, the motor gets hotter than the cylinder. The head was well below the temperature cut off switch rating. But that was with the cover off, so maybe there is a possibility of trapped heat in the cabinet either tripping the high temp cutoff at the cylinder head, or the thermal switch in the power supply
But what has seemed to eliminate the early shut offs for me was to clean out the check valve. Mine had enough grease on to partially block it. My early shut offs happened during the first 5 hours of use, so maybe it was the factory grease amount that needed to be cycled and excess purged. I'm at 6 hrs 25 mins now.
I still think this is a good compressor for the price, but it does require some fiddling if you want to fill tanks. I do think that GX is very generous with their claims.

I received mine about 2 days ago. Iv been filling 2 - 700cc tanks alot...going on maybe 10 fills each tank... Has yet to shut off on me...fills to 4000psi no issues...im hopeful that it doesnt have your issues anytime soon...

Everyone that has one of these compressors should do this mod. It's easy, free and gives a real benefit. IMO, it should have come this way from GX.
How to cool a cs4 or cs4-i, even better than just bleeding the air pocket.
