QUick Set-up Guide
Connecting the air source
The Proton has a standard ASA to accept a screw in air tank.
First, make sure that the knob is all the way out by turning it
counterclockwise. Carefully screw in the air tank until it stops. Turning
the knob clockwise will allow air to flow into the marker from the tank.
To remove the tank, turn the knob counterclockwise. This will release
all the air in the marker and make it safe to remove the tank. We
recommend the use of compressed air or nitrogen air tank with a
maximum output pressure of 800 PSI.
Attaching a loader
Loosen the screw on the clamping feed neck with a 5/32” hex key and
insert the loader. Adjust it to the desired location and tighten.
Attaching the barrel
The barrel simply threads on. The barrel threads are autococker type.
Turning the marker ON
The electronic ON/OFF is located inside the trigger guard. Push the
knob inward to turn the board ON and pull out to turn it OFF. All three
leds will come on for 2secs and the marker will be ready to fire in
semi mode with the eyes on.
Adjusting the velocity
The Proton has an adjustable regulator in the handle frame that
controls the pressure in the marker thereby controlling the velocity.
The best way to adjust the velocity is to turn the adjusting screw
clockwise using a 1/8” hex key. This will be the minimum velocity.
Check the velocity with a chronograph and gradually increase the
velocity by turning the screw counterclockwise.
Trigger adjustment
The trigger has adjustments for pre travel, post travel and microswitch
activation point. These are adjusted via the set screws in the trigger
using a 1/16” hex key.
Adjustment procedure
1. Ensure that the air is turned off to the marker.
2. Turn the marker on
3. Turn the eyes off. Now when you pull the trigger you will hear the
solenoid valve clicking.
4. Adjust the pre and post travel position of the trigger to suit your
liking.
5. Pull the trigger and listen for the solenoid. Turn the set screw
clockwise until you hear the solenoid valve clicking. If you do
not hear the solenoid then the screw may be too far in. Turn the
trigger set screw counterclockwise until you hear the solenoid
click when you pull the trigger.
6. Check for proper function by pulling and releasing the trigger.
Standard firing modes
The firing mode is changed by pressing the lower mode button. The green LED will indicate the current mode. Pressing the mode button again
will cycle through the various modes. After 10 seconds the LED will turn off to save power.
Friring Mode Function Green LED Display
Semi-Automatic One shot per trigger pull at a rate of fire (ROF) determined by the user setting. Blinking once slowly
3 Shot Burst
Three shots are fired at a shot rate of 10 bps regardless if the eyes are on or off. If the
trigger is released before the three shots are fired the marker will stop firing.
3 quick blinks
Full Automatic Fires continuously at 10 bps while the trigger is pulled regardless if the eyes are on or off. Continuously blinking
Ramping 1 Fires in semi auto and ramps up to the max ROF when the trigger is pulled more than
the ramp engage parameter. (Parameter 4)
Ex. Ramp engage set to 5 bps. If the trigger is pulled more than 5 bps, the Proton will
start firing at the max ROF setting.

Intelligent break beam ball sensor system
The Proton has a break beam sensor system with eye shields that prevent any dirt from entering the sensor. The eyes can be cleaned by simply
removing the bolt and using a squeegee. If any malfunction should occur the software automatically overrides the eye function and reduces the
rate of fire. The upper mode button on the foregrip allows you to enable or disable the sensor system. The software detects the actual position of
the ball as it approaches the bottom of the breach. This is a more reliable way of ensuring that the ball is in position rather than using a time delay.
The in-position tolerance can be adjusted depending on the paintballs being used. If you are using relatively tough paintballs you can set the
precision to low. A high precision will ensure that the ball is fully in the breach which would be useful for fragile paintballs. Refer to the user
adjustable parameter section to change this setting.
Turning the ball sensor ON & OFF
The infrared ball sensor can be turned on and off by pressing the eye mode button. Briefly pressing the eye mode will indicate the current sta-
tus (ON or OFF). The eye function is indicated by the yellow led in the following manner:
One blink Eye sensor ON
Two blinks Eye sensor OFF
