New rifle not filling

[JasonTaty]

Hi just received my new Gamo coyote, it came charged and after about 50 shots it needed to be filled.
I connected the supplied hand pump but the gauge on the pump goes to 3000 but the gun will not fill.
I‘m I doing something stupid? I can see any reason

Sounds like the check valve on the fill port might be stuck or maybe the fill probe isn’t inserted correctly. I’d try pumping it a few times see it doesn’t sort itself out.

does air come out the fill probe when you pump?

I'm thinking the same thing about the check valve is stuck. Pump higher than the 3000 psi you've pumped so far and I bet the check valve will release.

This issue has been discussed MANY times here re: new guns not filling with a hand pump. Do you know or are you near anyone with a tank? The valve needs a stronger rush of air to keep it filling than the hand pump sometimes supplies. Once it gets broken in the problem should disappear but, initially, you might need that high pressure "push" to open your valve.

Jason,
Good suggestions, so far, try the fill probe alone, hooked up to the hand pump, to verify air flow. If OK likely one-way check valve in gun is jammed, or defective. (Manufacturer may have filled gun originally with a stronger air source than a hand pump forcing the defective one-way valve open.) Add a few drops of silicone oil to end of properly inserted fill probe and let sit overnight. If problem persists, contact Dealer. WM

Did you try cocking the gun, then filling?

Thank you so much everyone for your help
Yes it was the check valve

Just purchased a P-Rod . I shot it enough to be sighted in. Today I went to recharge the gun with my compressor. The gun fills to 2800 psi easily enough but when I purge my fill hose it drains down to 0 to 1000 psi. Any suggestions? I’m thinking the check valve is hung up but I don’t know any tricks to get it unstuck if that’s really the problem. Any help will be greatly appreciated.
thanks!!!

When you bleed it off are you hitting it hard and opening the bleeder sharply? Sometimes if you just barely crack it the check valve doesn't see enough differential pressure to seal. Just a thought..

You could try a bit of silicone oil in the fill port to lube the check valve.

Rich at Airgun Revisions suggested the same things. I did the silicone in the fill port and dumped the pressure in my fill line more quickly than I normally do. That did the trick!!!

I appreciate everyone making great suggestions and want everyone to know that Rich at Airgun Revisions personally called me on a Saturday night to help out

Many thanks to all !
