every 5 years by a DOT licensed agency.
• Keep exposed skin away from escaping gas when installing or removing the air/CO2
cylinder, or if the marker or air/CO2 cylinder is leaking. Compressed air and CO2
gasses are very cold, and can cause frostbite under certain conditions.

Air/CO2 Cylinder Removal

1. Read
Air/CO2 Cylinder Warnings
(page 13) before beginning the cylinder removal process.
2. Eye protection designed for paintball use must be worn by the user and any person
within range.
3. Follow the
4. Watch the marks on the cylinder and cylinder valve (as shown in Figure 9) as you turn
the cylinder approximately ¾ turn counterclockwise. This allows the air/CO2 valve pin to
close so that no air/CO2 will enter the marker.
5. Remove the barrel blocking device. Set the Selector Switch to a firing mode (F or FA).
Point the marker in a safe direction, and discharge the remaining gas in the marker by
repeatedly pulling the trigger until the marker stops firing (this may take 4-5 shots). If
your marker continues to fire, the cylinder's pin valve has not closed yet. The cylinder
pin valve could be longer than usual. Because of the variances in cylinder pin valve
parts, each cylinder varies slightly on exactly how far it has to be turned. Turn the
cylinder counterclockwise a little further and repeat this step until the marker does not
fire. Only then remove the air/CO2 cylinder.
NOTE: If during this step, you turned the air/CO2 cylinder and it began to leak before
you pulled the trigger, the cylinder O-ring should be checked for damage before any
re-assembly (see
6. After the air/CO2 cylinder is removed, again point and fire the marker in a safe direction
to verify the marker is completely discharged of gas.
7. Move the Selector Switch to Safe mode (see page 6) and install the barrel blocking
device (see page 4).

Repairing Air/CO2 Cylinder Leaks

The most common leak occurs from a bad air/CO2 valve O-ring. To replace a valve O-ring you
must first remove the bad O-ring and then install a new one. This O-ring is located on the tip
of your air/CO2 valve. The best valve O-rings are made of urethane. Urethane O-rings are not
affected by high air/CO2 pressures. These may be purchased from Tippmann or your local
paintball dealer. There is an extra O-ring in the Accessory Pack that came with your marker.
: If a new air/CO2 valve O-ring does not resolve an air/CO2 leak, do not attempt to
