8. Begin by setting your input pressure to @ 200 psi. Optimum pressures will vary from gun to gun
and gauges are rarely dead on accurate. Some experimentation with pressure is necessary for
best performance. These pressures are just a guide to get you started.
9. Use a 1/8th Allen wrench to adjust the Respirator to @ 110 psi. The gauge on the back of the
Impulse should show your Respirator pressure as you adjust it. Remember, when adjusting any
regulator down, you must shoot the gun for the new settings to take effect. Paintball gauges
are very inaccurate and may be off +\- 20 psi.
10. Shoot the Impulse with the pressures set at 200 psi going into the gun and 110 psi from the
Respirator and listen for shoot down. Adjust the Respirator pressure up until the gun cycles
quickly without shooting down.
11. Chronograph. If the velocity is low, turn the Respirator up. The Respirator works best below
160 psi. If the velocity is high, turn the Respirator down.
For Experts Only - We've had excellent results with the line pressure as high as 300 PSI. In order
to set your line pressure this high, you will have to remove the Smart Parts low pressure bleed and
install it in the back of the gun where the gauge for bolt pressure was while setting the Respirator.
We saw a huge increase in shots per fill with the line pressure up this high. Be warned, this may void
your solenoid warranty from Smart Parts.
Trouble Shooting - If your Evil Respirator is working like a sweet looking front cap and not
regulating, you have to grease the black poppet o-ring. With no air in the marker unscrew the front
cap of the LPR. With your 1/8 Allen Key remove the stainless adjusting screw. Then take out the main
spring. Next, remove the brass poppet with the black o-ring. Lubricate that o-ring with the Dow
Corning 33 grease that was included with your Impulse. Reinstall the brass poppet then the spring
and then the stainless adjusting screw. Next screw the front cap back on and try adjusting your
Respirator.
