How to Replace an Empty CO 2 Cylinder

2. Unscrew adjustment screw (counter-clockwise) "B" as far as it will
go.
3. Remove the regulator from empty cylinder "E".
4. Remove dust cap from new cylinder "E". Open and close valve
"A" quickly to blow dust from outlet.
5. With cylinder valve "A" in closed position, reattach regulator to
cylinder at "E". Be sure to include the CO 2 washer.
