Important safety topics and tips are discussed throughout all of the chapters. It’s important that the operator know the principles of gun handling safety and operation prior to firing the Airsoft gun. SAFETY GUIDELINES WARNING! Failure to follow safety guidelines may result in serious injury. Safety Distance The effective shooting range is approximately 75 feet. BBs fired from this Airsoft gun may travel further than intended. Make certain that you have an adequate backstop. Eye Protection Eye protection should be worn at all times when both shooting and maintaining your Airsoft gun. Protect your eyes from BBs under pressure while performing maintenance on your Airsoft gun. Assume Every Gun is Always Loaded Until you are certain the chamber is empty, treat every gun as if it were loaded. Do not assume the chamber is empty based on your memory or someone else’s words. Always remove the magazine and visually check to confirm the chamber is empty. Beware of Barrel Obstructions Ensure the Airsoft gun barrel is free of obstructions before you fire the gun. Even the smallest obstruction such as lubrication or a stuck cleaning patch can cause a misfire or malfunction. Muzzle Control Always keep the muzzle of the gun pointed in a safe direction. Never point the muzzle at a person or object that you do not intend to shoot. Keep Your Safety On Keep the gun’s safety on until your sights are aligned on your target and you are ready to fire. Keep Your Finger Off The Trigger Keep your finger off the trigger and out of the trigger guard until your sights are aligned on your target and you are ready to fire. WARNING! Airsoft BBs can be a choking hazard. Keep them away from children. ! ! PARTS LIST M11A1 NS2

Before you pull the trigger, make certain of your target and what is beyond it. The Airsoft gun should never be fired at surfaces such as rocks, glass, water, or other hard surfaces where BBs are likely to ricochet in unpredictable directions. WARNING! Adult supervision is required for any person under the age of 18. Failure To Fire If the Airsoft gun fails to fire, misfires, or malfunctions, do not look into the gun barrel. BBs can become lodged into the chamber, and serious eye injury may occur. Maintain Your Gun Properly Performing proper maintenance, as outlined in this manual, ensures that your Airsoft gun will be safe to shoot and will perform to its designed specifications for many years. Alterations, modifications or adjustments may damage your Airsoft gun, make it unsafe to shoot, and will void all warranty claims. Store Your Gun Safely Always store the Airsoft gun in a safe place, and out of the reach of children. Always transport the Airsoft gun in a carrying case. Never display the Airsoft gun in a public place. Keep the safety engaged, and remove the magazine before storing the Airsoft gun. Note: it is your responsibility to take every reasonable precaution to ensure the safe storage and transportation of your Airsoft gun. Orange Tip The orange tip on Airsoft guns helps Law Enforcement distinguish between the replica guns from their real firearm counterparts. Altering the coloration or markings required by state or Federal law so as to make the product look more like a firearm is dangerous and may be a crime. Operator assumes all risks and responsibility when doing so. Hazards of Being Mistaken for a Real Firearm Airsoft guns have been mistaken by Police and Law Enforcement as real firearms. A confrontation with law enforcement while carrying an Airsoft gun can result in serious injury or even death. It is strongly advised to operate the Airsoft gun at a safe and legal location. In the event that you are approached by Law Enforcement personnel, you must comply with their instructions immediately to avoid an incident. Alcohol, Medications, and Drugs Do not handle or operate your Airsoft gun while under the influence of alcohol, medication or drugs. Your Responsibility Your Airsoft gun is well-engineered and manufactured to the highest standards. It was carefully inspected before it was packaged and shipped from our factory. Its safe use depends on you alone. You are the ultimate safety device. Like many other devices, your Airsoft gun is safe unless handled in an irresponsible or uneducated manner. 20 ! 50 21 70 80 48 107 3 1 51 30 58 57 63 29 88 8 100 11 53 105 69 77 15 60 12 52 73 107 28 87 87 31 89 112 90 81 14 17 82 122 104 44 121 154 153 76 40 103 9 32 111 38 49 104 97 95 96 98 6 5 20 2 67 83 83 152 4 129 126 125 132 128 130 123 18 13 10 64 94 93 71 99 46 65 16 75 74 66 102 24 92 19 93 M11A1 NS2

2. Push the gas canister nozzle into the charging valve. (Make sure both the canister and magazine are inverted and in the vertical position when charging.) 3. Charge the magazine until gas overflows from the charging valve. WARNING: Avoid dropping the magazine. Sudden impact with a hard surface may cause damage to the magazine. Note: It is normal to have minor leaking from the charging valve during charging due to high pressure built up inside the magazine. It is recommended to keep the gas release valve slightly oiled. Room temperature is the ideal temperature for shooting. You may experience a delayed action if the surrounding temperature drops below 68º F. Note: Do not expose the magazine to direct sunlight or incinerate the magazine, as this may cause the magazine to burst. It is strongly recommended to empty the gas from the magazine after shooting. Be certain that the gas does not make contact with eyes or skin while being released, as any contact will cause cold burns. 18 OPERATING UNDER UNUSUAL CONDITIONS Unusual conditions are defined as any condition requiring special maintenance. Perform maintenance outlined for the climate similar to your operational area Extreme Cold: Operating an Airsoft gas gun in extremely cold temperatures is not recommended. Cold temperatures will cause the Hop-up Bucking to harden, reducing its effectiveness. Gas will not expand properly in cold temperatures, so both the cycling rate and power will be dramatically reduced. Extreme Heat: Operating an Airsoft gas gun in extremely hot temperatures is also not recommended. Leaving the gun in direct sunlight for long periods of time, or operating in extremely hot areas will cause the gas to over-expand, damaging the internal workings of the gun. The increase in internal pressure from the expanding gas can also damage the seals and cause leaks in the magazine. Dust or Sand: Dust or sand can get into a gas gun and cause malfunctions and/or excessive wear. Keep the gun covered whenever possible. Use lubricant sparingly, as lube naturally attracts dirt and other particles. After use in a dusty area, always field strip the gun (refer to Disassembly Section) and clean any areas you can reach with a soft, lint-free cloth. ! Charging Valve Magazine Catch Nozzle Magazine M11A1 NS2 Green Gas safety tips: • Check the canister for any cracks or leaks before using. • Do not expose the canister to temperature over 104º F. • Do not leave the canister directly over fire. • Do not heat the canister. • Keep the canister away from direct sunlight. • Do not leave the canister in any type of vehicle. 1 2 3

Green gas is a liquid propellant which tends to dry out the seals and o-rings. With lubricating silicone oil, it will extend the life of the seals and o-rings and prevent gas leaks. Use only the recommended 100% silicone oil, available for purchase at the Airsoft dealer where you purchased your KWA products. Any other type of lubricant may damage the products. Lightly lubricate the recoil spring, cylinder and moving parts with a few drops of oil. Lubricating the seals and o-rings are essential. Unload BBs from the magazine. Make sure the magazine is free of gas before lubricating the magazine’s charging valve and release valve. 6 1 2 4 3 5 LOADING BBs 1. Pull the magazine follower down until it locks. 2.
