replace the seals
lube it and clean it, chances are that's what it needs, use paintball specific oil, no motor oil or wd-40

It doesn't really matter what air system you have on your gun, it should fix the same way. Depending on the marker, you'll have to follow the manuals to dissemble it. The only air problem that could happen would be the CO2 freezing up in the regulator. The only fix is to set the gun down and let it un-freeze.
