Please read the instructions completely. INSTALLATION INSTRUCTIONS V2.5, SEPT 2003. SUPERSEDES ALL PREVIOUS INSTRUCTIONS. 1. Remove all air sources connected to the marker. Remove all paint. 2. Disassemble the marker until you can take out the valve. 3. Using a valve removal tool remove the old valve. Check to see if your marker is older than a mid-1996 Autococker (32,000 serial number or lower). If the Autococker has an older style air chamber skip to the AIR CHAMBER MODIFICATION section of these instructions. 4. Place the new o-ring on the new valve body. It should seat into the small grove on the o-ring seat. SEE FIG 1 for location. Lightly oil the O-ring. Use Extreme-Lube from AKALMP throughout your paintball marker. 5. Place a yellow Nelson valve spring on the back of the cup seal or equivalent. SEE FIG 1. DO NOT CLIP THE SPRING. (For more spring info, see Best Reported Setup.) 6. Place valve in the marker with a valve removal tool (don't modify the valve) with exhaust port up and the set screw chamfer showing in the set screw hole. SEE FIG 1. Using the new set screw that came with the valve, place set screw in the marker body and gently tighten down. Now, alternately tighten the jam nut and set screw until both are tight. Do not over-tighten. This alternating tightening action will help keep the valve body straight inside the bore. Now re-assemble the hammer with a yellow Nelson hammer spring or equivalent. DO NOT CLIP THE SPRING ENDS . This spring setting works well. (See Best Reported Setup.) You may need to re-time the trigger once the marker is reassembled. The timing for a low pressure marker should be a little more conservative than most high pressure markers. 7. Pull back the hammer and put air to the marker. For most markers the valve should seal right away. There may be a few valves where you have to fire the marker with air leaking out of it a little before the valve cupseal will seal. If the valve doesn't seal see TROUBLE SHOOTING. After the valve seals it's time to adjust the velocity. This valve design is a hybrid of two valve ideas, one is a spring controlled valve and the other is a pressure controlled valve. Adjust your Nelson spring adjuster all the way out to the lowest spring tension setting possible and leave it. To adjust the velocity, first check the air pressure settings based on what type of air system you have. Then follow velocity adjustment instructions. If you valve does not seal and continues to leak call AKALMP, Inc. for a replacement. 9. YOU NEED TO SHOOT PAINTBALLS, NOT DRY-FIRE THE MARKER TO GET THE CORRECT EFFICIENCY READING. The velocity fluctuations will vary depending on what type of regulator you are using. AIR PRESSURE SETTINGS ARE BASED ON YOUR AIR SYSTEM SET- UP - FOR LOW PRESSURE. A. Double regulated air system. (i.e. Using two regulators, the tank regulator and a second regulator on the marker) *** OLDER NITROGEN SYSTEMS SHOULD BE DOUBLE REGULATED, though it is a good idea to double regulate the new systems, also. *** Set your main tank regulator output at about 800 to 900 psi. to mimic the output pressure of a CO2 tank. Then set your second regulator at 100 psi and adjust the velocity by adjusting your second regulator input into the marker as specified in the velocity adjustment section of the instructions.
B. Single regulated air system. (ie. straight from the nitrogen tank regulator or a regulator on the marker with air supplied by a CO2 tank.) *** OLDER NITROGEN SYSTEMS SHOULD BE DOUBLE REGULATED, though it is a good idea to double regulate the new systems, also. *** Set the regulator at 100 psi output and adjust the regulator output to adjust velocity. (If your regulator has a slow response time, you may want to install an expansion chamber or a gas through grip to store up a greater volume of regulated gas.) C. CO2 users If you are using CO2 and a regulator, follow the double regulated air system since you already have your main tank pressure preset for you. CO2 will work just as well as nitrogen if set up correctly. For example, you may have a personal setup that starts with a 20oz anti-siphon tank that runs into a bottomline stablizer and then runs into a vertically mounted regulator. With this setup you shouldn't experience any freezing of the marker or velocity drop off. If you can't, or don't want to invest in nitrogen this method is a good way to go.
D. Unregulated CO2 users - USE A REGULATOR PLEASE! This valve was not designed to be used at pressures over 400 psi. Using pressures above 400 psi will void your valve warranty. (See Best Reported Setups for regulator information.) VELOCITY ADJUSTMENT. With the pressure regulator adjustment screw backed out or set at 100 psi, slowly start raising the pressure into the marker until the velocity raises to the desired FPS. Then, to lower the velocity, turn down the pressure so there is less pressure pushing the paintball. This method leaves the springs in a more balanced state which produces better results than changing spring tension all the time. It also puts a low pressure push on the ball which creates less distortion on the paintball & gives better range & accuracy. If you are using just the Tornado valve you may have to do some extra work on the marker (i.e. other specific low pressure components) to get the pressure as low as 150-230 psi. Most prefer this setting because of the bonus of low pressure and you still get 2500 shots plus on a 114 cu tank.
