This is where taking photos before you pull anything apart is a good idea

[@keithjurena9319]

Very good service video. This is a three stage compressor, the compression stroke is stages 1 and 3, the piston moving down compressses air behind the piston, the V shaped copper tube moves 2nd stage air to the 3rd. It is excess grease from the lower shaft seal which migrates into the high pressure side that causes the dirt that jams valves. I have run silicone oil through the compressor, one drop at a time over 5 minutes of running, to clean valves. It takes about 5 ml of silicone oil to clear all debris. I wrap a paper towel over the outlet to catch the dirty oil. This completely restores like new function. Great idea on the hour meter. A 12 volt hour meter wired parallel to the motor should also work.

[@bobberguy6584]

Thanks for posting this video! I am pretty mechanically inclined, but, I have never serviced a high pressure air compressor before and this walked me right through it. I did do things a little differently when it came to disassembling mine. But overall, your camera work and details made this a breeze!👍🏼 my compressor runs better than new now!

[@airshootist]

You are the exact target audience for this! Awesome!

[@stevengoodman3498]

Great tutorial man. I've got a small toauto compressor that quit pumping completely. Now i have the courage to take apart and try what you have done here to maintain the compressor. If it still doesn't work after trying this i wont be out anything except time. Thanks a million! 😊

[@airshootist]

They tend to work again after a good cleaning. Just be deliberate and organized in your disassembly. Also snag the oil and grease I linked to in the description. You will need that for sure.

[@parkerazz4385]

Great information! Will definitely be adding one to my tool kit sometime in the future

[@NIRAJPATELV]

Superb Information Thanks

[@williammcguire1823]

This video is a god send. Mine is a Vevor, but the only difference that I can see is that there is a plastic air intake hose that attaches to what appears to be a filter of some kind to the case. I left to comment on Vevor Video. I think from watching this video, what the tech from Vevor is a cylinder is actually the piston. I’m going to watch your video again then take mine apart and clean it up good. Hopefully it will work without having to wait another three weeks for the part to come from China unless you know a place to source them in the US.

[@michaelb.42112]

OH cool, I found this link from Airgun Nation !

[@tenseken]

Really helpful got the same from your recommendation. And if you hold the start button for about 5 sec it will change the reading to fahrenheit

[@airshootist]

This thing is an absolute workhorse! If you grabbed it through my link you helped me afford about half a tin of pellets, so thanks king!!!

[@tenseken]

And also hold the start button to 5 sec to change the reading to fahrenheit

[@jeffojibway9284]

That compressor worked sweat shop hours!! Way to stress test it!

[@airshootist]

Bro... It says max like .5L tanks, meanwhile I'm filling 1.4L tanks (90 ci Ninjas) and all manner of guns DAILY with this thing, all to 4500psi. It is my best compressor, hands down.

Bottom of that air compressor case looks bent where the motor mounts

[@airshootist]

Yeah I noticed that too. It's had a hard life, gets banged around in my truck a lot. It takes a lickin' and still keeps kickin'!

[@stedyone1090]

Interesting

[@crypto_creep8222]

First for the homie ❤

[@drewbear82]

Hello. I found you from Amazon from the review that you did on the Orcair compressor. That compressor seems rather impressive. Full disclaimer, I haven't watched this particular entire video. Do you still recommend the Orcair compressor, or is this one worth the extra expense? Thanks.

[@airshootist]

The Orcair from that video is good if you're on a budget. However they just released a new digital compressor which is awesome for a little bit more. Not sure how the new digi one will stack up to the ToAuto A3. The ToAuto is a WORKHORSE

[@drewbear82]

@@airshootist awesome man. Thanks for the reply! I will take all this info into consideration as a make my decision. Thanks.

[@Wickedstickyflowers]

Mine had digital display Maybe different Probably a connector of some kind I’ll go slow

[@WaschyNumber1]

For what in the front side is the brass screw in the left upper corner? 🤔

[@airshootist]

It's just a little vent/filter. Not attached to anything on this compressor but on my Vevor it has a tube going to the compressor head. On the ToAuto A3 it is not used, but present for some reason.

[@WaschyNumber1]

@@airshootist thanks

[@rizco8543]

Hey bro I did all this but now I hv a new problem. I saw some water coming out of the release valve. So I opened it up again and saw water inside the piston. Hv any idea what is the issue?

[@airshootist]

Yep! You absolutely, definitely, certainly, for sure need to close the bleed valve after every fill and run the compressor with nothing attached to drain the condensation. Every compressor will build up water and you need to purge it. I just took apart my Vevor since it would stop pumping and found water in the cylinder. This was my own fault for not draining it after every use, when I found that water I definitely kicked myself! I could have just purged it rather than fully disassembling the compressor! Lesson learned!

[@rizco8543]

@@airshootist TX a ton really helps. Riz.

[@LoveU-pakS1S1e]

Sir our air gun compressor doesn't make pressure. I also changed some leaking joints but it does not make air pressure .Sir what's the reason.

[@KenE808]

👍

[@KenE808]

Hello, I have a vevor 4500psi. I think it’s basically the same item. While filling it completely shut down at approx 2300psi. Nothing turns on like no power is getting into the machine. Any clues/opinions? The compressor is less than a month old and has been very moderately used. Your insight would be greatly appreciated. Thank you

[@KenE808]

Oh by the way, the DC connection works. It must be the power supply system

[@WaschyNumber1]

Does it have a automatic bleed off? 🤔

[@airshootist]

No. You bleed it manually. It does have an auto-stop, though.

[@WaschyNumber1]

@@airshootist thanks

[@WaschyNumber1]

It's China made, how do people get replacement parts and in the warranty it says if somethink is broken by normal use, you have to send it back on your own costs.

[@airshootist]

They are super good about warranty stuff. In fact, I just had the piece that holds the piston to the motor break and they instantly sent a new part out and now mine is back to running 100%! This thing is a major workhorse!

[@WaschyNumber1]

@@airshootist nice, they send me a wrong main power cable for the UK, I have ordered it over amazon UK and they sebdbit over amazon us. I hope they can help me too, if I have problems like thst in the uk.
