Tuning PCP not holding air pressure

[KL]

I have a Sam yang Dragon claw 50 cal PCP. Now it's not holding air when I fill up the tanks. Is it possible that the O-rings may be bad? Are there any videos out showing how to repair the O-rings?

Any help is greatly appreciated thank you!

Are you bleeding your tank quick enough?

Is this the first time filling? Have you cocked the gun?

 

[Odoyle]

Is it leaking at the fill port or through the barrel?

If it's leaking through the fill port make sure it's totally degassed empty zero air and unscrew the fill port and if its still the older probe type use the probe as leverage to unscrew and flip that seal upside down and screw it back in again.

Thanks, I'll give this a try. It is the first time I fill the gun up. And I was unaware about crooking the gun before filling. I'm try this also.

Let us know if it's OK after cocking it then fill slowly and be sure to bleed it quickly as possible when filled (don't forget to decock the gun by holding the bolt open handle firmly while pressing the other hand/finger presses and hold the trigger then slide the bolt forward slowly).

It appears that Will from Saddle Mountain has died. I need help with repairing an air leak and finding parts for a Sam Yang Light Hunter that I purchased used. Anyone have suggestions?
