Filling the Air Venturi Alpha tube from empty

When filling your Air Venturi Alpha Tube from empty, make sure the gun is unloaded and point the rifle in a safe direction.

1. Locate your fill probe and verify that both o-rings are in place and undamaged. 
   
2. Pull dust cover forward, if you feel resistance, rotate the dust cover so the moderator goes between the reliefs in the dust cover. 
   
3. Firmly insert the end of the fill probe with the o-rings into the hole that was exposed when you moved the dust cover.
   
4. Cock the rifle.
5. Hook up the female quick disconnect of your HPA system onto the exposed male end of the fill probe.
   
6. Do not fill past 3600 PSI (250 BAR / 25 MPa).
7. Bleed your HPA system quickly and disconnect from the fill probe. 
8. Decock your rifle by pulling and holding the cocking lever back, depress the trigger, and slowly moving the cocking lever forward. If the cocking lever is not held back while depressing the trigger, you can damage your rifle.
9. Enjoy.
