Bill is right, the most logical thing to do is return or exchange it- contact the supplier and make sure you get a return label from them before you send it back. PCPs are not that hard to work on, but if it's still under warranty return/exchange is the simplest. In many cases if you open up the gun it may void your warranty. Who did you buy it from?
 
I had a air leak problem, from the get-go with my Disco and started out differently so I can say from experience . . .

Straight to Crosman if possible.

I used one of their warranty shops first and then had to send it to Crosman to fix his repairs.

1/2 cost of the gun in shipping around

Crosman (NY) fixed it and it is good to go over a year later (held air all winter when I did not shoot it) and has spit out a bunch of pellets.
