have you oiled your o rings?.....the one that came out of yor power tube seems to happen sometimes.

take the barrel off and put a couple of oil drops in the asa (the hole where you put the cos tank) and fire it a few times. also cock the gun before charging

I kept on trying, then a washer fell out of the power tube.  That scared me.  I sent it away to tippmann and waited.  I got my gun back two days before my next big game, supposedly good as new.  It shot fine that next game and I was happy again.  Then I tried to pressurize the A5 this morning and all the CO2 leaked out of the barrel immediately.  What the heck's wrong with my marker?

The problem may be all about me(meme) Have you read any of the stickies about troubling shooting and maintenance? Have you looked at the exploded views? Get over your panic and your need to blame someone and read up on the piece of equipment you know so little about. The ruggedness and dependability is no small part of the reason why Tippmanns dominate the rental market. Look at the parts of the marker; from paint job and gas connections to how the power valve works and the hammer recocks after each shot. The A-5 is simple, straight forward and easy to understand if you take the time.
