M11A1 NS2 GENERAL MAINTENANCE FOR KWA GAS BLOW BACK 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.
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.
