HOW TO GAS UP YOUR GUN FOR A WHOLE DAY OF PAINTBALL
1. When you first gas up your Timmy for a day of paintball, screw in your tank (or turn on the on/off ASA). Your gun will pressurize and you will be able to fire it.
2. Take a hex wrench and back the set screw of your LP Reg out (counter clock-wise) until it is flush with the end cap. Do the same to the HP reg. Fire your marker a few times as you do this and you will immediately notice that the system loses pressure to the point that it will not cycle (Kinda like when you de-gas a CO2 bottle from a marker).
3. After both reg screws are flush and the gun cannot fire, slowly begin turning the LP reg screw in (clock-wise) in small increaments (i.e. 1/16 of a turn) as you fire the gun. Keep doing this until your main gauge reads 85 psi. Now your opperating pressure is set.
4. After you have set the operating to 85 psi, slowly screw in the set screws in the the HP reg (clock-wise), until you see about 4 threads. This should put you in the neighborhood of 250-310 fps.
5. Go to a chrono and fine turn the HP reg setting until your marker is shooting at the velocity you want.
6. DO NOT DE-GAS YOUR GUN FOR THE REST OF THE DAY. Bob keeps his marker pressurized until his is done for the day. Only use your power on/off switch to disable your gun.
What this does is reset the tensions on the HP and LP reg springs. When you first gas the gun up, the gas pressure in your tank slams full force into the HP and LP regs. It takes time (i.e. many shots) for the springs to correctly adjust from a state of non-pressure, to a state of consistant pressure.
The idea of steps 1-5 is to slowly introduce pressure into your gun's system instead of 'shocking' it. Just think of the Regs as faucet valves in your sink. Be nice to them !
The idea of step 6 is to keep the springs in your regs under consistant pressure so your gun will have consistant velocities throughout the day. Good consistant spring pressure = good consistant regs = good consistant air pressure on the balls = good consistant ball trajectories = good consistant ACCURACY! Let's say you play 10 games, and after each game you de-gas your gun. That's 10 times your reg springs have to reset! How do you expect your regs to be consistant?
