OPERATIONAL INSTRUCTIONS
GETTING STARTED
Read this entire manual before using this launcher. Keep
your launcher pointed in a safe direction at all times.
1. SAFETY - Place the T8.1 in safe position by moving safety
so no red is visible. The safety is ambidextrous and can be
operated from either side of the T8.1.
* Visible red indicates that launcher
will discharge.
2. UNLOADING MAGAZINE - Ensure that there are no
projectiles in your marker by placing your hand under the
magazine, pressing the magazine release, and pulling the
magazine free from the T8.1.

PROJECTILE FOLLOWER
3. REMOVING THE BARREL - Ensure that there are no
projectiles remaining in the marker by removing the
magazine and looking through the grip into the breach.
Then you can remove the barrel by pressing on the end
of the barrel and rotating it counterclockwise. Note the
channel in the barrel and the barrel lock in the receiver as
it slides free. To reattach the barrel, line up the channel
with the barrel lock, slide the barrel back in the receiver,
push on the end of the barrel, and turn clockwise until
the barrel locks into place. Pull on the end of the barrel to
ensure it is properly seated.

4. LOAD PROJECTILES - Place 8 projectiles into the
magazine from the top. The projectiles will be held in place
automatically by the projectile retainer pin. You can also
lock the ball pusher in the down position by pulling down
on the ball pusher ears and locking them at the bottom of
the ball pusher track.
NOTE: FOR INSTRUCTIONS ON FIRST STRIKE ROUNDS,

5. LOADING C02 CARTRIDGE - Obtain a 12 gram CO2
cartridge. Insert the CO2 cartridge into the CO2 slot of the
magazine with the small end of the CO2 cartridge pointing
up and into the puncture pin of the magazine. Next, rotate
the flip knob base screw clockwise quickly until the
cartridge has sealed.
LOAD PROJECTILE
RED SPRING/SILVER SPRING
When using First Strike™ projectiles, make sure the red
magazine spring is installed. The silver spring is designed
for use with traditional .68 caliber paintballs. While the red
spring can be used with traditional .68 caliber paintballs, its
higher tension increases the risk of the paintballs deforming
over time.
LOADING FIRST STRIKE
Always load First Strike projectiles so rounded nose exits
barrel first. Always chronograph with First Strike before use
to ensure velocity is below 300 fps.

If you experience more than a small number of broken paintballs, check the following:
1. First, be sure that the marker is free of broken paintballs and other debris.
2. Second, make sure that the barrel is locked in its correct position, and that both detents are
installed so that they catch a projectile as it enters the breach.
3. Third, make sure the maker is set to a reasonable velocity (never over 300 ft. per sec.)
4. Check bolt assembly. Remove bolt from upper receiver and check for bad o-rings or debris
5. Check magazine for debris.
6. Load rounds in magazine (without CO2 cartridge installed) and engage PROJECTILE
RETAINER PIN - confirm that rounds can be ejected from the magazine without issue.
