Each Ski-Doo comes with an operator's guide and snowmobile safety guide that detail the basic knowledge required to safely operate a snowmobile. One must be familiar with not only the machine itself, but also how the machine acts on different surface. As a snowmobile operator, you will encounter hard snow, deeper snow, ice and even dirt or road crossings on occasion. Your machine will act differently on each, and knowledge of how this occurs is very helpful. One of the single most important things to know is your own limitations – do not exceed your own knowledge or ability. With experience you will gain even more knowledge and ability to be a safer rider.
