Just got a new alias earlier this month. There's nothing to it really.
Just screw the reg in below the behemouth pressure guage, screw in a 90 degree air hose adapter. screw on ure tank, hook some hose up and away you go!
Make sure when you install your rail or drop forward you take the side of the grip frame off to make sure none of the screws puncture the battery in the frame (I sooo nearly did that!)
Adjust the HPR pressure (looking at the massive guage) using the 3/16 allen screw at the front of the gun below where u screw in the barrell. Should read about 80psi or so.
The 2K2 manual is the correct manual. The board info in there is not completely correct tho. I receieved a seperate sheet about the new boards.
Ask if any of the Lions are about when you pop down as quite a few of us use timmies now. One of us would help you out.
Good luck and let her rip.
