Congratulation on your purchase of a wOrr Game Products, Inc. Autococker Auto-Cocker. This gun was manufactured from the highest quality aluminium and rust resistant stainless steel. Before leaving the factory, your Autococker was thoroughly inspected and test fired to ensue years of reliale, trouble free service. You own the finest auto-cocker paintball gun on the market today.
Please remember this gun is not a toy, and it is capable of inflicting serious injury to people and animals if not used properly. Most gun accidents happen because the shooter carelessly violates the most important rules of safety. Prior to loading and firing the gun, always make sure that all people within the range of the gun (including yourself) are wearing approved eye and head protection. Always insert the barrel plug when not on the playing field.
This gun is not a toy and must be kept out of the reach of children.
CAUTION: DO NOT OPERATE THIS GUN WITHOUT
EYE PROTECTION. DO NOT PUT ANY PART OF YOUR BODY DIRECTLY IN BACK OF THE COCKING BLOCK WHEN YOU ACTIVATE THE TRIGGER. WHEN THE COCKING BLOCK IS IN THE REARWARD POSITION, DO NOT PLACE ANYTHING BETWEEN THE COCKING BLOCK AND THE MAIN BODY. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY CAUSE DAMAGE TO THE GUN AND POSSIBLE GRIEVOUS INJURY TO THE OPERATOR.
The Autococker fires from a closed bolt. The auto-cocker system only activates during the last half of the trigger pull. The final portion activates a three way valve that allows CO2 to enter the front side of the activating cylinder. This in turn pushes the cocking block backward approximately 1" and moves the bolt and cocking rod backwards. At this time the hammer latches and a paintball drops into the breech.
The bolt and cocking assembly remains in the rearward position until you release the trigger. Releasing the trigger reverses the three-way valve. This vents the CO2 from the front of the activating cylinder and routes CO2 to the rear of the activating cylinder. The cylinder then pulls the cocking block and bolt into the forward position. The gun is now ready to fire.
The first half of the next trigger pull releases the hammer, firing the gun, and the second half of the pull repeats the above steps.
NOTE: This gun will not shoot liquid CO2. Do not use a siphon tube bottle or mount the bottle so liquid enters the gun (e.g., California Sniper or Bottom Line). You must have these styles of mounting equipped with an anti-siphon device in the CO2 cylinder prior to use.
NOTE: Always make sure you,and everyone
around you, wears eye protection when you adjust the gun or check for paintballs in the
gun.
When you recieve your Autococker you must make an adjustment to the regulator before use.
Before making any adjustments to your Autococker check the barrel to make sure there are no paintballs inside. You can do this in one of two ways. The first method is to remove the barrel from the gun and look in it.
The second method is to remove the bolt from the gun, force a cleaning rod through the cocking block towards the front of the gun, then remove the cleaning rod and insert the bolt.
Once you are certain that there are no
paintballs in the gun and feeder system, and you have your eye protection on, you are ready to make your adjustments. Refer to the illustration (below) and the appropriate
section of this maual while adjusting your Sniper.
After checking that there are no paintballs in the gun, your first step is to locate the pressure regulator. It is house inside the fore-grip of the gun. Slide the fore-grip straight forward to remove. Always hold the gun pointing away from you, and others, with the barrel plug installed or the barrel removed.
1. Do not remove, only lossen the knob at the forward end of the regulator (about one turn counterclockwise). If you remove the knob while the gun is under pressure, the spring and piston may fly our of the regulator. Always point the regulator toward the ground for safety.
2. Install CO2 source.
3. Pull the trigger all the way back, as if you were firing the gun, and hold it back.
4. Slowly turn the regulator adjusting knob clockwise. This causes the cocking block, at the back of the gun, to move backwards.Continue turning the adjusting knob slowly until the cocking block touches the cocking knob. Now cycle the trigger (pull and release), and continue to ver slowly turn the regulator knob clockwise untill it fires. It is important to cycle the gun after each adjustment of the knob. Do not turn the regulator knob any farther than it takes to cock the gun. Over pressurizing the regulator damages the system.
5. The system requires very little adjustment after the initial setting unless there is a large temperature change.
NOTE: The three-way valve actuating rod should never need adjustment unless the rod is removed. Never remove the rod unless there is a problem with the air reciever or the three-way valve.
In the event the rod requires adjusting, follow these steps:
Two things affect the bolt backward travel:
To check the cylinder adjustment, remove the cocking rod, pull the cocking block backward until it stops, and look down the feed tube to see if the bolt tip has cleared the feed tube hole. If it does not clear the hole, refer to the Cocking Block to Cocking Cylinder Adjustment section of this manual. If the bolt does clear the hole, the cocking rod, perform the following steps:
To replace the hose, follow these steps:
NOTE: Always were eye protection.
It isn't necessary to completely disassemble your gun to clean it.
This is all that you should need to do to clean you gun.
NOTE: Do not use synthetic based oil or any lubricant other that 10 weight or lighter oil. (3 in 1 or sewing machine oil is recommended.) USE OF ANY OTHER LUBRICANT VOIDS YOUR WARRANTY AND YOU BECOME RESPONSIBLE FOR ALL REPAIR COSTS.
To adjust the Sniper's velocity
Many players talk about how efficient their guns are, and often brag about how many shots they get form a 7-oz. bottle. In designing the auto-cocker operating system of the Autococker we needed to know the theoretical mass of CO2 required to cycle the gun.
Our first step was to determine what equation was appropriate for our needs. Through some calculations we determined that the Ideal Gas Law (PV = nRT) would give us the mathematical accuracy that we needed.
Our constants and variables were as follows:
P = Working pressure in atmospheres.
V = Cylinder volume in liters.
n = The number of Moles of CO2.
R = The Gas Constant in liter
atmospheres/Mole/degree Kelvin.
T = Operating temperature in degrees Kelvin.
We calculated many combinations of working pressures and cylinder sizes to determine the best performance possible. The final product uses a 3/16" bore, a 1" stroke, and a working pressure of 150 psi. We calculated usage based on an ambient operating temperature of 25 degrees C.
For the system the volume (V) = Pi x radius2 x stroke. Or V = 3.14 x (3/16)2 x 1 = .1104 cubic inches = .0018 liters.
The pressure (P) = 150 psi/14.7 = 10.20 ATM
The temperature (T) = degrees C + 273 = degres Kelvin = 25 + 273 = 298.
Using the Ideal Gas Law we get: 10.20 x .0018 = n x .08206 x 298
Some simple maths giver us: n = .00075 moles of CO2 = .033 grams.
This is for one firing cycle, or two strokes, of the gun. To fire the Autococker 300 times would take less than 1/3 of an ounce of CO2. The efficiency of the auto-system using a 7-ounce bottle is an outstanding 95.5%
