Technical information

When the gas flows into the ON/OFF chamber, the gas pressure pushes the ON/OFF PIN, which in turn
depresses the rear of the trigger sear. This action raises the front portion of the sear which captures the bolt
and pushes the trigger into the 'firing position' (Usually audible as a faint 'click').
The bolt, which is held in position by the sear, seals the valve, preventing gas from flowing down the
barrel.
The gun is now ready to fire.
When the trigger is pulled, the following actions occur:
(1) The sear pivots, releasing the bolt and depressing the ON/OFF PIN
(2) The ON/OFF PIN prevents gas from flowing from the regulator into the valve
(3) The bolt is pushed forward by gas pressure from the valve.
(4) The bolt pushes a paintball into the barrel
(5) Once the bolt has traveled completely forward, the gas in the valve is released, firing the ball
(6) The BOLT SPRING pushes the bolt back, where it is again captured by the sear, completing the cycle
and preparing the gun to fire once again.
2-6. REMOVING THE PROPELLANT SOURCE
There are four different basic configurations of propellant source tank attachments. These are:
ASA Bottomline attachment
ASA Vertical attachment
Tank-to-valve attachment
Remote line attachment
Additionally, all of these configurations can be set up with or without a quick-disconnect fitting, with or
without a check-valve (an in-line on/off bleed valve) or a variety of other fittings, such as a reducer or
elbow.
Both CO2 and regulated compressed N2 or compressed air systems, depending upon the manufacturer and
user configurations, can utilize any of these attachments.
CO2 and regulated compressed N2 or compressed air systems which attach directly to the gun (either
vertically or bottomline mount) are removed using the same procedure:
Follow the unloading procedures found in section 2-4. Next -
(1) Insure that the valve on the tank has been turned to the OFF position if the tank is provided with an
on/off valve. (Consult the tank manufacturer's instructions for this procedure.)
(2) Point the gun barrel in a safe direction.
(3) Grasping the tank firmly, turn the tank counter-clockwise. Make sure to observe the valve and insure
that the valve is turning with the tank. (If the valve is NOT turning with the tank, STOP IMMEDIATELY
and seek qualified assistance.)
(4) Approximately every quarter to half turn of the tank, pull the trigger; this allows you to relieve pressure
on the tank's o-ring, giving the o-ring longer life and making the tank easier to remove.
(5) When the tank valve has been unscrewed approximately half-way, any gas remaining in the gun will be
able to vent out of a small relief hole which is built in to the bottomline or vertical adapter.
WARNING: Loose valves on propellant source tanks can be extremely dangerous. It is of the utmost
importance that you insure that the valve unscrews from the gun, and does not unscrew from the tank, when
removing the tank. You can make this procedure safer by placing a mark on the valve and the neck of the
