The patented T-4-E quick pierce system lets you put a CO2 cartridge in select T4E markers without puncturing it until you are ready to use it. When a new unpunctured cartridge is in a marker at the ready just strike the quick pierce knob at the bottom of the grip to instantly charge the marker with CO2. The patented Quick Pierce system is ideal when you want your T4E gun ready but not yet charged with air.
Always keep your T4E marker pointed in a safe direction. Remove the knob at the bottom of the grip. Turn it counterclockwise. Place a drop of silicone oil on the tip of the cartridge. Drop the CO2 cartridge into the grip with the small side facing the bottom of the grip. Put the knob in the bottom of the grip and turn it clockwise. Finger-tighten it until it stops. There is no need to use a tool to tighten it.
When you are ready to charge your T4E marker, grip it in your dominant hand. Strike the quick pierce knob with your other hand. This instantly pierces the CO2 cartridge. Point the marker at your target and pull the trigger.
To remove a punctured CO2 cartridge and replace it with a new one you must first let the air out. Unload any remaining projectiles according to the owner’s manual. Point the marker in a safe direction and fire until it will no longer shoot. If your T4E marker has a pressure indicator press it in so any remaining air can escape. Now remove the knob at the bottom of the grip by turning it counterclockwise. You should not need a tool to remove the knob.
The patented quick pierce system and your T4E marker are easy to use. Drop a new CO2 cartridge into the grip. Hand tighten the knob. When ready to use it, strike the knob at the bottom of the grip, point at the target, and pull the trigger. When you’re done using your T4E marker, unload any remaining projectiles according to the owner’s manual, shoot the air out of it, press in the pressure indicator, and allow any remaining air to escape. Then remove the knob, discard the used cartridge, and reload.
