    Umarex "Umarex Notos Update HUGE power Upgrade!" Or is it?

    Not sure if there is a better location. If so, tell me. However, I designed this up while Firewalker was upgrading my notos. Here is a picatinny mount that clamps around the barrel and .22L bottle with two 3mm screws and nyloc nuts. I tested it out yesterday with my pic to arca adapter and...

    GX CS4 Overheating issue

    I returned that filter immediately once I saw it had the wrong fitting. The one with the red cap on the end. I didn't want to mess with finding the right fitting.

    GX CS4 Overheating issue

    Sucks you got a lemon too. At least you'll get your money back and have a compressor to play with. It still works, just not sure how long it will last.

    GX CS4 Overheating issue

    When I insisted on a return/refund they had the nerve to insult me. I shouldn't post their last response, but I can't help it. Get out your popcorn.... The iphone reference was icing on the cake! From GX: Hello we said it is not defective. in other words, you returned to us to repair, we...

    GX CS4 Overheating issue

    That is unfortunate, but that is what I thought GX would say. I haven't checked the water temp with the temp sensor disconnected. I will do that when I fill my bottle up next time. Did you use paypal to pay through the GX website? I submitted a dispute, printed the entire email conversation...

    GX CS4 Overheating issue

    Sounds like you got a hot unit like I did. Contact GX (email) and maybe they will send you a different video on the CS4-I. If no resolution, submit a paypal or CC dispute. I was able to restart the unit after power cycling. I hope you can get it to run again after letting the unit cool down...

    GX CS4 Overheating issue

    The video is to test temp and pressure. They told me to just disconnect the temp sensor. I think they use that video for troubleshooting multiple issues.

    GX CS4 Overheating issue

    Update: After a long email exchange with GX with no acceptable resolution, I filed a PayPal dispute and included all email traffic. The seller never responded to PayPal so I got a full refund. Now I guess I can try all of the cooling tips everyone provided.

    GX CS4 Overheating issue

    The motor doesn't sound like it is working too hard. I'll try and flush the radiator. The converter? The power supply? It is a S-650-13. Unfortunately, I had to open up a paypal dispute

    GX CS4 Overheating issue

    Plug/deadhead test: Cold 0 to 300 bar: 24 seconds Hot 0 to 300 bar: 24 seconds (coolant water at 150.8 deg F) Fill from 220 bar to 300 bar in 46 minutes. Unit does not stop running prematurely after disconnecting the temperature sensor. I'm still not happy with this halfhearted 'fix' from GX.

    GX CS4 Overheating issue

    Garage is around 75 deg F. I'm measuring the water in the reservoir with an instant read thermometer. I tried another thermometer as well with the same result. I just disconnected the sensor. Running it now to see what happens.

    GX CS4 Overheating issue

    After further clarification, this is not going well. They state "i mean disconnect the temperature sensor, if it does not happen again, you don't need to connect it anymore, our factory is planning to cancel it." Requested exchange or return for refund. Response "it is not defective. pls test...

    GX CS4 Overheating issue

    Just an update: GX is saying that it may be the temperature sensor. They sent me a youtube video showing someone disconnecting the temp sensor. I'm not sure disabling the temp sensor is the fix for this. I think we're having some language barriers but I hope to work this out with them soon.

    GX CS4 Overheating issue

    Plan on it. Purged the grease, but not much came out after 2 hours. After 20 mins of use, the circulating water got to 151 deg F and the unit shutdown. I'm in communication with GX and we'll see what they say.
