Just bought this pump, instruction manual sucks! Anyone know where I can get better assembly and operating instructions?
Nothing to it, There are several you tube videos showing people using them. Just make sure that you release the pressure before removing the pressure hose from your gun or tank.

its easy to use.
Put oil in it and put the long vented cap on in place of shipping cap
hook up water pump and bucket of water
install air hose and put in filter use Teflon tape
screw in both bleed valves one on each side of compressor
turn it on and open bleed valve when you ready to turn it off.
I would put little oil water cotton filter on end of air line it’s not showing one ,they sell on eBay $15 or you can get a good bigger one.

It would really help if you would post a link to where you bought the compressor from....we are airgunners, not mind readers...
One photo is a slim clue to follow!

The pump in the photo is not a Yong Heng but was probably made in the same factory. Does it have any branding on it at all? There is plenty of tips on how to assemble and operate on Utube if you are uncomfortable with using the thing without destructions. It's not rocket science.
View attachment 1527053618_20928152955b04fd32918a94.23641206_Yongheng instructions.pdf Here is the Yong Heng owners manual, It's probably the same as the one supplied with yours.

There's a metal pin at the rear of the pump head that must be removed for the unit to operate.

The metal pin that you're referring to sounds like the thermometer probe. If it has a wire leading under the housing? leave it be.

Yea you need to put that back so you know your temperature of the compressor if that’s what you talking about.
A lot of people talk about adding ice or changing the water in the bucket. I don’t use the pump or a bucket. I’m sure there is a lot of ways to similar that you could do but I use mine in the utilitiy room so here is what I did. I put a garden hose splitter on my cold water for my washer machine put a little pointy hose sprayer on it and connect my hose to it than I put the drain hose where the washer drains the washer hose holds it in there firmly than I adjust the water flow. I’m sure there is other ways to do it that might be more convenient in your situation. My splitter was already on my faucet so all I had to do was walk outside and get the little sprayer thing off my hose and I was pumping up my tank.

Yeah, you're right I put it back in and pump operates normally, I just had a hell-of-a-time getting pump to loosen up initially

Did you understand what I was saying about the cooling system? Many different ways it could be done. Like a sink faucet, just go to hardware and find something that fits the threads and reduce it to fit the hose. You can even get a longer hose so it can reach a more convenient spot away from wifey.

Thanks, I'm gonna to try to find some adapters because the water fittings that go into the pump head are prone to leaking.

And..once I put the "thermometer probe" she seems to heat up really fast, from say 27c to 44c in less than a minute!

i bought a tile wet/saw pump from home depot (royobe) puts out more water than what came with my compressor also i ad ice and run mine for 30 mins to fill a 109 cu/ft cf tank and it never reaches over 45c temp

That’s normal temperatures. It can’t make a change in your tempature. When it’s disconnected your temperature gauge isn’t working so how are you reading your temperature? It might go up a little when it’s disconnected room being close to the compressors heat but it’s not a true reading unless it’s in the head. So the compressor is heating up the same but you are just not aware of it.

Sonny; the only reason I do it like that is for convenience. The way I got it set up all I have to do is slide the hose on and turn the water on at desired volume and start the compressor. The way you got yours set up is a nice set up also ,as long as you get’er done.

Thanks for all your help! Pulled a muscle in my back (several times) using a hand pump, Bro and Sis-inlaw gave me the pump for my birthday (May 23rd). And like I said earlier Chinese instruction manual sucked. With your help I'm figuring out how to work this thing!

One very important tip. Do not attempt to start the unit whilst it is pressurized. The back pressure will stall the pump and eventually kill the motor. Always start with the bleed screw open and close it when the pump is spinning. The model that is in your photo is by the look of its features, is a Jufeng type. I have heard that Jufeng is the manufacturer that makes Yong Heng, Tuxing,Davv, and a few other brands. As for one or the other being better made, is not true. It's just a lottery like with a lot of Chinese goods, with if you get a good one or a bad one. I am sure that a lot of problems that have been experienced by users of these things, has been caused by ignorance, more than by dodgy product. It would be certainly worth their wild to supply a decent English speaking engineer to write proper owners manual for the things.
