Shootdown
If you're using CO2 System
If
you're using Compressed Air or N2 System
(co2) 1. Make
sure tank valve/pin valve is fully open. Next
(co2) 2. Check
for line restrictions such as crushed/clogged filter, kinked hose,
etc. Next
(co2) 3. Ensure
liquid CO2 is not getting into the valve
Next
(air) 1. Is
the tank valve fully open and output pressure set to 800 psi?
Next
(air) 2. Is the
supply tank filled to over 800 psi? Next
(co2/air) a. "Short

nut until it is loose again, reattach air source and re-chrono
the gun. Next
