Evil LPR User Manual

EVIL Respirator LPR
Instruction Sheet

Here is the abridged version. This implies that you know enough to de-gas your Impulse
and take all the paint out. As always, if you do not feel comfortable taking your Impulse apart,
please take it to someone who will not destroy your equipment. If you have questions,
please call 1-800-579-1633 and ask or email us at [e-mail].

Warning! Read all instructions before starting.

1. Remove the front valve cap.

2. Take off the vertical asa or front grip and inspect to see if there is a set screw underneath the
Tapeworm side of the gun. Some Impulses have the set screw under the asa holding the
Tapeworm in place and others have the set screw on the other side of the asa. If yours has a
set screw under the Tapeworm side, the set screw has to be removed before removing the
Tapeworm. If you have a set screw on the Tapeworm side, but you don't have a Tapeworm,
that set screw still has to be removed before installing the Respirator. If you have a
Tapeworm, it has to be removed once the screw is out and then the threads have to be
cleaned before proceeding.

3. For best performance, the Respirator should be installed with an Evil Valve. If you wish to keep
your stock valve, you will have to cut your stock valve spring to fit. If you're using the Evil
valve, use the spring that comes with the kit, but you won't use the big black plastic spring
guide.

4. If you aren't installing an Evil Valve, skip to step 5. Install the valve from the back. Make sure
the o-rings are properly greased with the large hole towards the front of the gun and the
larger non-through hole facing down. If the valve does not slide into place, use the alternate
70 durometer o-rings provided in the package or the stock o-rings off the stock valve instead.

5. Unscrew the front cap of the Respirator. Grease the o-rings on the snake (the part that goes
in the hole normally reserved for a tapeworm). Slide the snake in until the Respirator threads
flush up against the body of the gun where the valve cap was screwed in. Use a wrench on
the flats of the Respirator to turn the Respirator while pushing evenly with your thumb on
the snake.

6. Once the Respirator is screwed all the way into place, use a 1/8th Allen wrench to back out
(counterclockwise if looking at the front of the gun) the Respirator internal adjustment screw
until the top of the adjustment screw is flush with the Respirator itself. Screw the Respirator
cap back onto the front of the Respirator.

7. Once the asa is back together and the tiny set screw under the asa is reinstalled with some
sort of thread sealer, reinstall your vertical regulator or front grip. Install a low pressure
gauge on the back of the gun that can read in the 50 to 200 range. This gauge should be
removed once the Respirator is set, it is just to be used as a guide for setting up your
Respirator. Some people put their low pressure bleed back in that port, especially if they up
their line pressure over 200 psi. Air up and check for leaks.

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.
