builds up, it can increase the chance of chopping a ball in the future. Q-tips work well to clean the hopper area. Also remember to thoroughly clean the barrel. Operation The Tippmann A-5 uses an inline blowback system. Propellant Before gassing, cock the marker by pulling back the cocking handle (located near the front of the marker on the left side of the receiver). This pulls back the front and rear bolts and allows access to chamber while also ensuring that the valve is not being depressed by the rear bolt when the propellant supply is screwed in, which would result in a leak. A click should be heard. Release the cocking handle. Screw a propellant supply (CO2, N2 or HPA) tank onto receiver or remote coil. Operator should hear a sound as marker becomes pressurized. Hopper and loading Press the manual-feed button (located to the right of the receiver, on the Cyclone Feed System) and check Cyclone Feed System for proper rotation of sprockets. It should be clean and free of debris. Attach a compatible hopper to the marker by placing the mouth-end (male) of the hopper into the Cyclone Feed housing (female) and turning hopper until tab on mouth locks into corresponding hole in feeder housing. Hopper should be parallel with marker. Open hopper flap and fill with paintballs (up to 200 for standard hopper). Close flap until it snaps onto hopper mouth. Preparing to fire Pull back on the cocking handle located on the opposite side of the marker from the cyclone feeder (this is only required once each time a propellant bottle is connected). Press the manual-feed button to force a paintball into the chamber. Disengage safety by pressing the 'Push Fire' button located above the trigger on the right side of the grip frame. A red line on the left side of the button indicates when marker is ready to fire.
