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.
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.
