Air leak above left side of Expansion chamber

[gsxlimitd]

Ok...when i first got my A4 a few days ago, i made sure that i tested it out and fired about 500 dry shots because i saw that some people were having problems with air leaks on first hook up. I didnt have any leaks...but today when i went to play everytime i would turn my air on you could hear a slight air leak coming out of the little hole right above the left side of the expansion chamber. has anyone had this problem?? how do i fix it??? thanks

Expansion chamber!?

You are shooting CO2 through your A4!? :shocked:

- Check the tightness of the 2 screws that attach the Flash Tank Assembly to the body. You can see diagrams for this assembly on pages 24,25,28,and 31 in the manual. You may need to remove and reattach to ensure a proper seal.

- Tighten the pressure gauge if necessary. Hand tighten!

Check that and then report back.

I had this exact same problem. Lube up the o-ring on the LPR brass piston.

Ok...i lubed up the lpr brass piston...but i still have the leak when i turn my air on....the pressure gauge is tight...any more suggestions???

Try putting on another o-ring and then lubing that one up.

just thought id mention this.. there is a little o-ring between the flash tank and the body of the gun itself maybe that needs to be replaced or lubed?
