It is self-bleeding, but you can speed up the process by making sure the cylinder is full of fluid before re-installing it. After assembling the cylinder, put a couple of short lengths of tubing on the AN fittings. Stick those into a jar full of new hydraulic fluid. Extend and compress the actuator until all the air bubbles are gone. It's easy and quick, and when you re-install the cylinder, you ar= e not introducing much air into the system.
