JT Impulse maintenance and operation manual WARNING • THE Impulse IS NOT A TOY. • MISUSE OF THE Impulse MAY RESULT IN SERIOUS INJURY OR DEATH. • EYE PROTECTION DESIGNED FOR PAINTBALL USE MUST BE WORN BY THE USER AND ANY PERSON WITHIN RANGE OF THE Impulse. • JT PAINTBALL RECOMMENDS THAT THE Impulse ONLY BE SOLD TO PERSONS 18 AND OLDER. • THOROUGHLY READ THE Impulse OPERATION AND INSTRUCTION MANUAL BEFORE OPERATING. • TREAT EVERY PAINTBALL MARKER AS IF IT WERE LOADED. • NEVER LOOK DOWN THE BARREL OF A PAINTBALL MARKER. • KEEP YOUR FINGER OFF THE TRIGGER UNTIL READY TO SHOOT. NEVER POINT THE Impulse AT ANYTHING YOU DON’T INTEND TO SHOOT. • KEEP THE Impulse ON SAFE (POWER OFF) UNTIL READY TO SHOOT (SEE QUICK START). • KEEP THE BARREL BLOCKING DEVICE ON THE Impulse’S MUZZLE WHEN NOT SHOOTING (SEE BARREL BLOCKER SECTION). • ALWAYS REMOVE PAINTBALLS AND DE-GAS THE Impulse BEFORE DISASSEMBLY (SEE DE-GASSING SECTION). • STORE AND TRANSPORT THE Impulse UNLOADED AND DEGASSED IN A SECURE PLACE. • FOLLOW ALL MANUFACTURER’S WARNINGS AND INSTRUCTIONS FOR PROPELLANT SOURCE HANDLING, STORAGE AND FILLING. • DO NOT SHOOT FRAGILE OBJECTS SUCH AS WINDOWS. • ALWAYS MEASURE THE VELOCITY OF PAINTBALLS FIRED BY THE Impulse BEFORE USE, AND NEVER ADJUST TO FIRE ABOVE 300FPS (91.44M/S).

Barrel Blocker / Battery 2
Barrel Blocker
alkaline battery
Barrel Blocker The barrel blocker is a very important piece of safety equipment – as important as goggles. It is used any time the Impulse (or any other paintball marker) is connected to an air source and is in an area where people are not protected by paintball goggles or paintball field netting. The barrel blocker performs a very simple function. If the Impulse is accidentally fired, the barrel blocker catches the paintball to prevent accidental injury or damage. Although turning off the Impulse does serve as a safety mechanism to prevent it from firing, the barrel blocker has an advantage in that it is clearly visible to everyone that it is in use. It is important to make sure that the barrel blocker is securely in place when it is used. To put the barrel blocker on the Impulse, slide it over the end of the barrel and loop the cords over the back of the marker. Adjust the cord lock so that the barrel blocker is held snugly in place and cannot slip free.
Pro Tip: Because the barrel blocker is visible to everyone and works with all markers, it is the standard safety device used any time the Impulse is handled in safe zones where goggles are off.
Battery The electronic components in the Impulse are powered by a single rectangular 9-volt battery. For optimal performance, alkaline batteries (ANSI type 1604A) should be used. Lower cost “heavy duty” zinc/carbon batteries do not last nearly as long, or deliver amperage as reliably and should be avoided. Most “9v” style rechargeable batteries will work with the Impulse, but their charge levels may not be accurately reported on the Impulse display. It is advisable to gain experience with any particular rechargeable battery before trusting an important game to it. Installing or changing the battery in the Impulse is simple. Use a 5/64-inch allen wrench to remove the two grip screws from the left side of the marker and open the rubber grip. The battery simply slides into place, contact side up. Battery orientation is important. The positive terminal of the battery (smaller of the two snap conectors) should be aligned towards the Impulse display screen, while the negative terminal (larger snap) should be towards the barrel. With the battery in place, close the grip and secure it with the two grip screws. Make sure the circuit board’s battery contacts are pressed firmly under spring pressure against the battery terminals. If the fit is loose, slight bending of the contacts may be necessary. Because the Impulse circuit board draws a very small amount of current from the battery even when it is turned off, it is best to remove the battery if the marker is going to be stored for a few weeks or more.

ASA LOCK SCREW
HPA The Impulse is designed to be powered by a high pressure compressed air (HPA) system only. Use of carbon dioxide (CO2) to power the Impulse is likely to cause damage to sensitive internal seals and will result in a voided warranty. Paintball HPA systems consist of an air storage cylinder rated to 3,000 psi or 4,500 psi and an integrated regulator/valve installed in the neck of the cylinder. HPA systems are typically divided into high-output (800 psi) and low-output (400 psi) models. Either type will work with the Impulse, though use of a high-output model will often deliver more consistent velocity at high rates of fire. HPA systems are shipped empty, and must be filled by properly trained persons. Once filled, the HPA system is attached to the Impulse by screwing it in to the bottom-line ASA (See ASA). ASA The Impulse is equipped with a bottom-line style venting on/off Air System Adapter (ASA). Before screwing an HPA system into the ASA, make sure the ASA is turned off by turning the on/off lever forward. After screwing in the HPA system, the ASA may be turned on by turning the on/off lever back parallel with the ASA body. The ASA lever should be turned on slowly, so that the gas pressure inside the Impulse rises gently, rather than with a sudden “pop.”
WARNING: When removing an HPA System from the ASA watch carefully to make sure the HPA system regulator is unscrewing from the ASA and that the HPA cylinder is not unscrewing from the HPA regulator. WARNING: Never put oil or other hydrocarbon products in an HPA system or its fill nipple.
When turning the ASA off, gas trapped between the ASA and vertical regulator will be released with a brief hissing sound. This is normal. Turning off the ASA does not completely de-pressurize the Impulse and may leave enough gas inside the marker to fire 2 or…
