TSS on CO2 needs wake-up shots. Is it normal?
I notice that if I leave my CO2 powered TSS a few hours or even overnight, the next time I pick it up, I’ll have to fire minimum 5 – 8 blank shots to “wake up” the gun. Those first 5 – 8 shots are very weak with very little CO2 being delivered. After these intial shots, everything would back to normal. I asked Tom Gaylord about this, he said it’s normal for almost all guns. Sure, I can understand the intial shots might be low, might be a bit erratic, but what I observed with my TSS is just way too peculiar. Can any of you help me understand this? TIA.

Damn, I probably got the one you sent back 😀
Well, actually at this moment, it is irrelevant because I have already sent the gun, the adapter and the CO2 bottle all back to PA and I am buying the HPA setup with a free CO2 adapter from Compasseco with only $60 more.
You are right – I should be able to measure the distance, but I didn’t.
Thanks.
Had one do that….sent the adaptor back to Airforce.
But if you think the stem is not being seated all the way into the seal when you first shoot, then wouldn’t the gap between the top hat and valve body be larger? Should be able to measure the distance just out of storage vs. when shooting right.
I am traveling today so I will pop in occasionally. What could also be happening is there is some gunk in your valve that is restricting motion of the stem and it takes a few shots to get it moving.
This could be a possible cause.
WOK, that was my first suspicision too. I let the gun rest with muzzle pointing up overnight, the next morning same scenario happened again. Now, you probably remember this picture
where I busted the O-ring and popped the valve stem out of the CO2 adapter while trying to disconnect the 12oz CO2 bottle from the adapter. The reason I was trying to do that is because the wake-up shots made me think my tank was empty and guessed perhaps PA didn’t fully fill up the tank when shipping my gun. I think the problem is that my valve stem does not sit tightly inside the CO2 adapter or the valve body. Pressurized CO2 pushes the valve stem out of its normal position. What the dry-fires do is simply hammering the stem back a little bit just enough to get the CO2 going.
This is my speculation, of course, and I am no expert whatsoever. In any even, I have already gotten the RMA# from PA and I’m going to ship the whole thing back to them and buy another new setup. For where I am and what I am shooting at, CO2 is great. After all it costs only $2.50 to refill the bottle. Thanks for all your advices on AF guns.
Chances are you are getting some liquid inside the valve and it takes a few shots to get it out.
Do not store or carry your gun with the tank tilting down.

Doubt it…they sent it bck (repaired)…in the time between, had hunted up another one.
Would be best to store the adaptor with pressure in the tank and the bolt closed/hammer down…might help keep the valve seal seated to the stem.
Believe dry fire would increase the likelyhood of the seal slipping from the stem, but haven’t run a lot of tests to prove it one way or another.
