Trouble Shooting my new PCP

[TattoosByJohnnyV]

I just got a Seneca Eagle Claw .22 lever action in the mail today. Came with about 2000psi in the main tube. took some shot that brought it down to around 1000 psi.

When I went to hook it up to my hand pump to get it up to it optimal max fill pressure, I successfully reached the "200 Bar" and when I went to bleed the hand-pump valve, all of the air from the rifles main tube came out....bring it main tube down to Zero. and now after two attempts to refill it from zero to 200 Bar it keeps doing the same thing and empting the rifle all the way down to zero. 



If anyone can help trouble shoot the issue it would be greatly appreciated.

Thanks!

Either you are not bleeding fast enough (open bleed as quick as you can) or the check valve in the fill is not sealing.

Try cocking it after your done then bleed it. And that sucks and a ton of work lol.

Thanks for the advice, I'll give it a try.

Could be some trash in the check valve as noted above. If you can find someone with a tank, filling that way with the higher flow might dislodge any trash that may be in the valve. Doesn't sound like a problem that would be addressed by cocking the gun. And bleeding faster is probably helpful too.

I want to know how you got a gun delivered by email?

I'd take a look at the fill vlave. How it's designed. Some simply have an oring that's held against the inlet. Tightening the oring retainer can help.



I was going to say bleed faster as well.

 

[TattoosByJohnnyV]

Yes! Pumping the Rifle up to 200 Bar and then Cocking the lever action followed by bleeding the valve rapidly worked perfectly. Thanks so much everyone!

Try bleeding faster without cocking the gun. Seems you should have the same result as cocking the gun would seem to only help when the gun will not fill at all because it is allowing air to flow out of the valve. As for most experiments, change one thing at a time.

We'll have to see next refill.

Some guns do seem to need to be cocked in order to build ANY pressure during filling. If not cocked, pressure on the valve causes air to leak out while filling. Good to know if one owns that type gun. This does not seem to be what you were describing, which is a system that built and held pressure until bled. That suggests a fill check valve issue, not a main firing valve problem. In any event, glad you got it shooting.

I have the exact same issue with my eagle claw when I try to use my electric compressor. I can't seem to get the bleed valve to go fast enough and invariably lets all of the air out. I've done it five times and even though it is an electric compressor and only takes about three or four minutes, after you do this for 40 minutes you get a little frustrated. I like to use the electric compressor because I have three filters, a cigarette size, then a carbon filter about 5 inches and then a foot long molecular separator packed with desiccant.

The only way I was able to get it to work was to use my SCBA tank and the fill whip has a fast bleeder and then I'm fine. 

My initial gut reaction was to send this thing back to fix it but I guess it's a common issue in the design. If it didn't have a magnetic tip on the fill port I would just buy one that has a one-way check and unscrew the one that it came with and replace it. I guess I'm going to be making a phone call to air Venturi and pyramid air and see what their thoughts are on that because it's not fun if you're out in the field and run out of air and can't fill it!

When possible is better to buy one of the following: Airgun Technology, FX or Daystate

Lil late to the party on this subject but figured I'd put my 2 cents in if anyone finds this later. My Eagle Claw was the same way when I first received it. I saw in a YouTube video (believe it was A.G.D) they noted the same issue. Suggested filling the gun vertically with barrel on the ground and then bleeding as quickly as possible. It worked for me. But now after filling it many times I no longer need to do this, guess it broke in.

i have a old korean fire 201 shin sung 9mm you had to have the gun pointing down for the valve to close , also if the gun was empty you had to cock the gun to take pressure off the poppet (valve)
