1
After each adjustment fire two clearing shots to gain an accurate velocity reading. Never
exceed 300fps.
2
High, mid and low pressure output preset air systems can be used with the GEO3.1, providing
the GEO3.1 has the SL4 inline regulator originally supplied with the marker.
3
Turning the SL4 adjuster screw in too far will prevent the GEO3.1 from firing.
