These are general guidelines or instructions for Gas Airsoft Guns (pistols only). 

How to use a gas gun:

Remove the magazine from the pistol by pushing on the magazine release.

With the magazine removed:

Fill the magazine, with the magazine below the gas canister

Make sure the can is ALSO upside down. Make sure they are both perfectly in line and completely vertical. Do not tilt sideways at all or angle the green gas canister and the gun magazine. Make sure the nozzles get a firm seal, and proceed to fill the "Liquid" into the mag by pressing firmly down with the airsoft gas canister. Filling time depends on the mag capacity. A normal handgun mag is generally about 5 seconds. A 50-round mag is usually about 8 seconds. This will insure you get a full charge of gas, for the amount of BBs.

After loading the green gas into the magazine, load the BB's. Simply pull down on the magazine follower and insert BB's.

Next, simply reinsert the magazine into the gun. After the gas has been loaded, magazine has been loaded with BBs, simply cock the gun as shown below and you're set to go:

What NOT TO DO when filling the mag:
If you fill the mag, and gas begins to spill, STOP. Let the magazine warm up at room temperature before attempting again. This is usually about 5-6 minutes. If you are able to form a tight seal and fill correctly, allow the magazine to warm to room temperature. Tapping the big metal button on the top, rear side of the mag will discharge the GAS from the gun magazine. DO NOT do this! It will prematurely wear out the seals and also cause the O-rings to freeze, damaging them permanently. Instead, fire the gun until out of gas. This is the safe way to discharge a gas-gun.

Fire the gun in WARM weather. Using during the cold seasons are not advised. They will not cycle completely, fire well, and will use more gas than normal. Rapid-firing of the gas-gun will also cause the gun to freeze up, resulting in damage to the magazine or gun. These problems are not as prone during the hotter seasons or warmer weather.

Use HIGH grade BBs for your guns. Lower quality BBs will tend to jam in the magazine well, preventing proper firing. Excel, Blaster, Qbullet or Goldfire BBs are are highly recommended. These are all models which we carry. Using .12 or cheap chinese BB is not advised for higher end airsoft guns, such as electric or gas and will VOID THE WARRANTY and may cause permanent damage.

Gas-Gun care:
Be sure to keep your slide and all moving parts lubricated with SILICONE oil which can be purchased on our website or at your local hardware store. Do not use anything else, such as petroleum based lubricants. ONLY 100% pure silicone oil is required. Other lubricants are not safe for use on plastic and rubber parts.
Do not use WD-40, and other petroleum based lubricants will damage the guns permanently.

Be sure to also spray silicone oil into the top nozzle of the magazine well every 5-6 magazines uses. This is done, by pressing the top release valve on the the mag while putting a quick spray of silicone into the top rubber exhaust valve. This will keep the seals and O-Rings properly lubed for a lifetime of use.

Recommended gases for gas airsoft guns:

KWC: use ULTRAIR Gas only for these guns. Use with Red Gas will void the warranty

KSC/KWA: use HFC134a gas unless equipped with a metal slide. If equipped with metal slide use ULTRAIR Green Gas. Use with Red Gas will void warranty.

Western Arms: HFC 134a gas is recommended. Use with any other gases (such as HFC22 or Green Gas) will void warranty.

KJW, Y&P, STTI, HFC, other Taiwanese guns: ULTRAIR Gas is recommended. Using HFC134a is not powerful enough. Use with Red Gas will void warranty.

Maruzen, Tokyo Marui: HFC 134a gas is recommended. Use with any other gases (such as HFC22 or Green Gas) will void warranty.

Marushin: HFC 134a gas is recommended. Use with any other gases (such as HFC22 or Green Gas) with void warranty.

Tanaka: HFC 134a gas is recommended. Use with any other gases (such as HFC22 or Green Gas) will void warranty.

Storing your gas-gun magazines:

After usage please leave or insert a small amount of the appropriate gas, enough for 2 - 3 shots is recommended. Do not keep them in storage while fully charged or completely empty. This will allow the O-Rings of the magazine properly lubricated while in storage. Ideally use small amounts of 134a maintenance gas to keep valves and seals lubricated.

Handling methods
There are instances where pellets can be fired and not be fired. Sometime, two pellets are produced at the same time. Magazine is too cold Place in normal temperature or heat with palm.
Loose breech score. Re-bolt tightly.
Defective or deformed BB pellet. Use normal BB pellet.
Magazine is defective or damaged. Deformity of magazine outlet or magazine outlet machine. Replace abnormal parts with new ones.
over-adjustment of recoil (hop-up) mechanism. Move adjustment screw up
Unable to close slide stop pin (slide malfunction/cannot be closed) Magazine is too cold/amount of gas is inadequate. Stop use prior to restoration of normal temperature. Restore gas capacity. Add oil on nozzle rubber. Load gas.
Oil in piston section has been used up. Wipe with oil. If problem persist, it is mostly due to deterioration of O ring replace¨with new parts.
Loose breech scores. Screw tightly
Cracked cylinder. Replace with new parts.
Defective or malfunctions of trigger burr Check if there are chances of reducing scratches to slide¨if yes, replace with new parts.
Magazine output machine is damaged Replace with new parts. (output machine cannot reach normal position, clean ammunition chamber)
Abnormality of magazine nozzle rubber Wipe with oil. If problem still persists, immediately replace with new parts.
Lubrication of slide track not adequate Wipe oil on slide/frame assy track. If problem persists, send for repair.
Piston ting is deformed. If slide stops in the middle, there may be a piston ring embedded in cylinder. Replace with new piston ring.
Slide Stop Pin SP is deformed. Replace with new parts.
Gas spurt out when trigger is pulled Defective magazine installation. Reinstall until magazine lock is fastened.
Inadequate gas pressure inside magazine. Replenish gas. If temperature of magazine is too lo, wait until it is restored to normal temperature.
Deterioration of Piston O-ring. Add oil. If problem persists, replace with new one. Problem may be due to cracks in cylinder. Check and confirm.
Unable to load gas into magazine Temperature of magazine to high Press discharge valve, loosen discharge valve to reduce internal pressure. Wait for magazine to restore to normal temperature and load gas.
Inadequate amount of gas in air storage bottle/valve is damaged. Replace with all new gas storage bottles.
Load valve is damaged. Replace with new parts.
Gas leaks from magazine Inadequate oil causing poor seal Add oil (Please refer to items concerning Maintenance)
Load/Discharge valve is damaged. Replace with new parts.
Unable to load BB pellet into ammunition chamber Opening of magazine is deformed Under any condition, replace with new ones. (sometimes it may due to deformities of BB pellets)
Deformity of magazine output machine
Blank shooting of trigger Safety mechanism is closed Pull up safety lever, remove safety mechanism.
Trigger washer SP is damaged Replace with new one (Abbreviation for spring is SP)
Unable to shoot BB pellet (unable to eject gas even with hammer in down position) Gas is empty, gas leaks Reload gas to magazine. In case of gas leaks and coating oil on top of it is not enough to improve conditions, send for repair
Excess amount of gas High temperature or outdoor activates during the hot summer season are reasons for abnormal increase in gas pressure. Temporarily reload gas after temperature of magazine is reduced.
Deformity of SP in piston Replace with new parts.
Pellet stuck in rubber chamber Refer to One Point Clinic relating to Hop-up mechanism.
Poor magazine mechanism Install properly and insert magazine.
Pellet obstruction inside magazine May be due to foreign matter, deformity of magazine output machine, too small BB pellets. Remove foreign matter and replace with new ones.
Malfunction of impact hammer Replace defective parts (may also be due to abnormalities in safety mechanism/abnormality of link parts of impact system)
A bullet falls out of the muzzle Rubber chamber destroyed Replace.
Loose SC in inner barrel Screw tightly (Use bolt screws)
Trajectory disorderly (winding trajectory, poor target accuracy) Abnormality of BB pellet Avoid using irregularly sized, defective and deform pellets. Use round BB pellets.
Abnormality in link parts of barrel Replace with new parts once there are scratches or deformities in internal parts of rubber chamber/inner barrel.
Coordination between parts inadequate Lubricate slide, frame-assy, gun barrel and other movable parts with oil, waters and wheel.
Holding and gripping gun arbitrarily Avoid shaking wrist, grip tightly when shooting. Grip gun with both hands.
