You must pull the tiller so far so you get the rudder up to the locked position, otherwhise it will fall down and drag behind the boat and it will be almost impossible to steer!
When you sail with one rudder the boat must be sailed "clean", that means no pinching and never loose boat speed. If you loose speed the rudder will stall quickly and you willm be forced head into the wind and stop, and loose a lot!
Sailing with one rudder is not always the highest priority. Use both rudders during the start and for short tacks.
