You will find there are stops on the housing which provide a physical limit when you are turning the nose wheel with a hand held tow bar. The trouble starts when you use a powered towing device and the turn limits are exceeded there is a good chance the limit lugs could be broken.

Some owners disconnect the bolt on the scissor link to allow the nose wheel to turn freely when they used a powered tug. If you go down this path you need to have a sure fire way of making sure the scissor link is reconnected prior to flight.
