  • Page 45: Riding Your Snowmobile

    ESS41401 RIDING YOUR SNOWMOBILE GETTING TO KNOW YOUR SNOWMOBILE A snowmobile is a rider active vehicle, and your riding position and your balance are the two basic factors of maneuvering your snowmobile. Riding your snowmobile requires skills acquired through practice over a period of time. Take the time to learn the basic techniques well before attempting more difficult maneuvers.
  • Page 46: To Start Out And Accelerate

    Set the parking brake and follow the instructions on page 7-1 ~ 7-2 to start the engine. Once it has warmed up, you are ready to begin riding your Snowmobile. TO START OUT AND ACCELERATE 1. With the engine idling, release the parking brake. 2.
  • Page 47: Riding Uphill

    Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the snow- mobile to tip. If your snowmobile begins to tip while turning, lean more into the turn to regain balance.
  • Page 48: Riding Downhill

    RIDING DOWNHILL When riding downhill, keep speed to a minimum. It is important to apply just enough throttle to keep the clutch engaged while descending the hill. This will allow you to use engine compression to help slow the machine, and to keep the snowmobile from rolling freely down the hill.
  • Page 49: Ice Or Icy Surface

    ICE OR ICY SURFACE Operating on ice or icy surfaces can be very dangerous. Traction for turning, stopping or starting is much less than that on snow. WARNING When you have to operate on ice or icy surfaces, drive slowly and cautiously. Avoid rapid acceleration, turn- ing or braking.
