To load a ballista, activate a ballista dart, right-click the ballista, and select Machine > Load.

You will then have the right-click options to Machine > Unload to remove the dart, Winch, Winch five laps, and Winch ten laps, shoot 1, 5, or 10 tiles further. This will start an action timer and each lap will take 1 second to winch. While winching, the winch at the back of the ballista is animated.

Having winched it, you can unload the dart, or unwind the ballista which results in an event log message. The ballista makes a whirring sound as you release the tension on the winch.

Right-click the ballista, select Machine > Fire, and watch your event log for messages. Firing the ballista will animate the model.
