Electrical Power Supply
The Impulse is powered by a replaceable 9-volt battery. With normal care and usage, the battery
should last for approximately 25,000 shots. It is recommended that the Impulse be powered only by
alkaline batteries.
Propellant C02 / Compressed Air Supply
NOTE: We do not recommend the use of CO2 or compressed air systems that use a pin valve. If
your air system uses a pin valve, it is highly recommended that you use an inline on/off valve to
eliminate gassing and degassing problems.
The Impulse is capable of using either C02 gas or a compressed air system (nitrogen system). For
compressed air use it is required to use the Max-Flo regulator specifically designed to work on low
pressure markers. Please follow all instructions included for the air system being used on
your Impulse.
C02
To use your Impulse with C02, your bottle will need to have an anti-syphon tube that is correctly fit-
ted to the Impulse to prevent liquid C02 from entering the marker. If your C02 bottle does not include
an anti-syphon tube or your anti-syphon tube does not correctly position onto the marker, call a
certified airsmith to install one into your bottle. Do not attempt to disassemble a C02 bottle or install
an anti-syphon device.
Compressed Air
The compressed air system installed must be able to provide a high volume of air regulated at
150-200 psi. If the compressed air system installed cannot regulate to the required pressure, a
Max-Flo regulator will be required as a secondary regulator.
NOTE: Some of the steps below will require you to activate and fire the Impulse. Please read the
section on Operating the Impulse (page 4) before continuing with the compressed air installation.
1. Attach the air system to the Impulse.
2. Adjust the air system output pressure to below 100 psi (turn the Max-Flo spring
cap outward). This is to prevent the Impulse from being over-pressurized the first
time the air system is turned on.
3. Turn on the Impulse. By default it will activate in “Eye-Off Mode”. This is the
correct mode for initially setting the input air pressure, do not change.
4. SLOWLY turn on the air system and increase the input pressure to 150-160 psi.
For accurate adjustment, fire the marker, and readjust if necessary.
5. Attach the barrel and a loader. Put paintballs in loader.
6. Change the Impulse to “Eye-On Mode”.
IMPORTANT: In Eye-On Mode, the first shot will always fire with or without
a ball in the chamber.
7. Adjust regulator pressure between 150-200 psi to achieve desired velocity.
NOTE: If your Impulse is using a compressed air system and a secondary regulator, set the
output pressure of the primary air systems regulator to 650-750 psi. Follow Step 4 to set the
output pressure of the Max-Flo regulator.

Impulse Operating Instructions
The following section will review standard operating instructions for activating, deactivating and
mode selection for the Impulse.
Activating the Impulse
To turn on the Impulse, press and hold the power
button for 2 seconds. The power button is located on
the back of the solenoid housing. Upon activation the
Impulse will beep once and the LED light will display
a slow double blink. The Impulse is now active and in
Eye-Off Mode.
Impulse Power & Eye Mode Button
Power Button
& Eye Mode
Deactivating the Impulse
To turn off the Impulse, press and hold the power
button for 2 seconds. When deactivated, the Impulse
will beep once and the LED will not flash.
Auto Shut-Down Feature
If the Impulse is not fired for 20 minutes, it will automatically deactivate and not fire.
Low Battery Indicator
When the battery level of the Impulse drops below 6.8 volts, the marker will sound an audible
beep every 5 seconds.
Setting the Vision Eye Mode
The new Vision Eye detects the dropping motion of the paintball into the Impulse’s chamber.
With the Impulse in Eye-On Mode, it will only fire when a paintball has been detected by the
Vision Eye and is in the chamber ready to fire. With the Vision Eye turned off, the Impulse will
fire every time the trigger is pulled regardless of the position of the paintball.
To change Modes between Eye-On Mode and Eye-Off Mode, press the power button once to
switch back and forth between the two modes.
IMPORTANT: In Eye-On Mode, the first shot will fire with or without a paintball in the chamber.
This is to allow the Impulse to fire if a paintball was loaded into the chamber prior to the
marker being turned on.
LED Display for Vision Eye Modes
Eye-Off Mode Slow double blink every second. This is the default mode for the
Impulse when it is activated.
Eye-On Mode Rapid 5 blinks per second. Between shots, the LED will flash at 5 blinks
per second if the next paintball has successfully loaded. If the next paint-
ball has not correctly loaded, the LED will flash 1 blink per second until the
next paintball is loaded successfully.

Impulse Adjustments
The following section will review standard adjustment instructions for the Impulse.
Vision Eye
The new Impulse Vision Eye requires no manual adjustment. All settings are adjusted
automatically by the circuit board programming.
Rate of Fire
The new Impulse has two default fire rates that do not require adjustment:
Vision Eye Off: 13.7 shots per second
Vision Eye On: 20 shots per second
Input Pressure Adjustment
The input pressure adjustment is made to the Max-Flo regulator included with the Impulse. The
operating pressure should be set between 150-200 psi, depending on the velocity desired. Please
read the Max-Flo operating manual included with the Impulse.
Increasing the pressure on your regulator
1. Turn the spring cap inward (clockwise), while watching the input gauge.
2. Fire 3-5 shots and then chronograph the Impulse.
3. Adjust the regulator until you achieve the desired pressure.
Decreasing the pressure on your regulator
1. Turn the spring cap outward (counter clockwise), while watching the input gauge.
2. Fire 3-5 shots and then chronograph the Impulse.
3. Adjust the regulator until you achieve the desired pressure.
Once your regulator is set to the desired pressure, you can lock it down by tightening
the spring cap locking screw.
Dwell Adjustment
The dwell is the amount of time that the Impulse solenoid
valve remains open. This controls the amount of air sent
through the solenoid valve to the hammer. The dwell
setting can modify the velocity of the Impulse and the
marker should be chronographed after any adjustments
made to the dwell or input pressure.
Impulse Dwell Adjustment Buttons
Dwell
Down
Dwell
Up
The dwell has an operating range of 4-14 milliseconds which
is adjustable in .25 millisecond increments. The higher the
setting, the longer the valve stays open, thus increasing the
air flow to the hammer.
Increasing / Decreasing the Dwell - Using a small flat head tool press the Dwell Up or Dwell
Down Button located on the side of the solenoid housing. Each press adjusts the dwell up or down
.25 milliseconds and can be verified by a single high-pitch beep for each press. When the dwell
setting has reached the limit of its adjustment, a rapid low pitch beep will sound.
Resetting the Impulse Operating Pressures
First reset the dwell by pressing and holding the dwell down button until a low-pitch beep sounds.
The low pitch beep indicates that you have reached the bottom of the adjustment range for the
dwell. Next, adjust your Max-Flo to the desired input pressure (150-200 psi). Finally, increase the
dwell until the desired velocity is achieved.

Impulse Maintenance
The following section will review standard maintenance instructions for the Impulse.
Changing the Battery
To change the battery in the Impulse, remove the two grip cover screws on either side of the
grip frame. Remove the old battery and replace with a new 9-volt alkaline battery.
Lubricating the Bolt
To remove the bolt from the Impulse, remove the bolt pin located at the top of the body and
slide the bolt out the back of the body. Wipe clean with a paper towel. Apply a generous
amount of Dow 33 Shocker lubricant to the bolt. While the bolt is removed, the inner surface
of the upper bore should be cleaned by pushing a paper towel through the body.
Lubricating the Hammer Piston
To remove the Hammer Assembly from the Impulse, remove the bolt pin from the top of the
body. Then use an adjustable wrench to loosen the hammer assembly from the back of the
body. After removing the hammer assembly, apply a generous amount of Dow 33 Shocker
lubricant to the stainless piston and holes at the rear of the assembly. Do not apply lubricant
to hammer head.
Cleaning the Valve
Remove the end cap and valve spring. Remove the Hammer Assembly from the back of the
Impulse. Push the valve out through the front of the Impulse. Do not use a tool or object with
sharp edges, as this may damage the inner surface of the body. Wipe the valve with a clean
paper towel, apply Dow 33 lubricant to the o-ring and reassemble.
Cleaning the Solenoid Spool Valve
Remove the two grip frame screws using a 1/8” allen wrench. (See Diagram on page 6-7)
Slowly move the body to the side of the grip frame and disconnect the wire harness that
connects the solenoid to the board. Remove the two end-cap screws from the solenoid and
remove the end cap. Using a pair of needle-nose pliers, pull the spool valve out of the spool
valve housing. Wipe the valve with a clean paper towel and apply Dow 33 lubricant to the o-
rings. Reassemble the solenoid, making sure that the marked side of the end-cap is correctly
reattached to the solenoid.

the Vision Eye cover and remove the Vision Eye screw. Remove the Vision Eye from the
Vision Eye slot and wipe with a clean paper towel or q-tip.
NOTE: The ball detent for the Vision Eye is longer than the standard ball detent on the
opposite side.
General Body Cleaning
The Impulse body and outer surface items can be cleaned with a water/alcohol mix applied to
a rag or cloth. Do not immerse the Impulse in any liquid.
Troubleshooting
The following section will review troubleshooting procedures for the Impulse.
Gun will not fire
- Verify correct air pressure from regulator.
- Check firing mode with Eye-On Mode and Eye-Off Mode. (See page 4 for setting
the firing mode)
- Verify that battery is charged and is an alkaline battery.
- Verify that the bolt pin is correctly inserted through the bolt and into the bolt actuator.
- Verify that bolt is inserted correctly, with the air input facing down.
- Reset dwell to zero and readjust to desired velocity. (See page 5 for resetting the Impulse
Operating Pressures)
- Verify that solenoid is correctly plugged into the circuit board.
- Verify that trigger is contacting the firing switch. (Set the firing mode to Eye-Off Mode
and verify that the LED blinks when the trigger is pulled.)
Air leaking out breech (barrel)
- Verify the bolt is in the open position. The bolt pin should be at the back of the groove
it cycles in.
- Clean valve. (See page 9 for instructions on cleaning the valve.)
Internal Air Leak
- Clean and lightly lubricate Spool valve with Dow 33 lubricant.
- Check o-rings on hammer assembly (See Hammer Assembly diagram on page 6)
- Change solenoid gasket.

Poor air efficiency
- Verify that air system has no leaks.
- Increase input pressure from air source and reset dwell to zero. From the lowest dwell
setting increase the dwell until the desired velocity is achieved. (See page 5 for resetting
Impulse Operating Pressures)
Paint Breakage (paint breaking in barrel)
For accurate troubleshooting related to paint breakage, please use premium quality paintballs
while troubleshooting the Impulse. Paint breakage may also be caused by other conditions
including incorrect bore size in barrel, misshaped paintballs or extreme weather conditions.
For Impulses without the Vision Eye or if the Vision Eye is in Eye-Off Mode the paintball load-
ing may break if the marker is fired before the paintball has fully dropped into the breech.
Also, for Impulse markers without a Vision Eye, the loader feeding the marker should be
motorized and have fresh batteries.
- Check that both ball detents are clean and properly holding paintball in breech.
- Verify that the Impulse is in Eye-On Mode and that the Vision Eye is correctly detecting
the paintball. (See page 4 for LED Display Modes)
- Decrease input pressure from air source. Increase the dwell until the desired
velocity is achieved. (See page 5 for increasing dwell)
Bolt remains forward when gun is fired
- Verify that a paintball is in the breech when the Impulse is fired.
- Reset dwell and increase until the desired velocity is achieved. (See page 5 for resetting
Impulse Operating Pressures)
