TROUBLESHOOTING
PAINT BREAKAGE
If you experience more than a small number of broken paintballs, then there are 4 things to check:
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 that the red First StrikeTM spring is not installed in the magazine (See page 10)
4. Fourth, make sure the maker is set to a reasonable velocity (never over 300 ft. per sec.)
MAGAZINE
If your magazine is leaking CO2, it is coming from one of three seals:
Valve Housing Seal (#2 - Page 30) - CO2 leaks out the top or bottom of the canister
CO2 Valve Spacer O-Ring (#6 - Page 30) - CO2 leaks when the magazine is inserted in marker
Housing O-Ring (#9 - Page 30) - CO2 leaks from the top of the magazine while the magazine isn’t inside the gun.
If the magazine is leaking slightly from this area, try inserting and ejecting into the maker 2-3 times. This may seat
the valve and eliminate the leak.
BOLT PUSH
When re-assembling the marker be sure to push the bolt forward before installing the regulator.
(See note on page 27.) To push the bolt the barrel and bolt spring must be removed from the marker.
