FOREWORD
Know Before you Go
To learn how to reduce the risk for you, your passenger or bystanders
being injured or killed, read the following sections before you operate
the vehicle:
–
SAFETY INFORMATION
– VEHICLE INFORMATION .
Also read all safety labels on your snowmobile and watch attentively
your
SAFETY VIDEO located at www.ski-doo.com/safety.
We highly recommend that you take a safety riding course. Please
check with your dealer or local authorities for availability in your area.
Failure to follow the warnings contained in this Operator's Guide can
result in SERIOUS INJURY or DEATH.
The proper functioning of a snowmobile depends in part on the sur-
face on which it is driven.
Driving on very hard or snow-free surfaces compromises the cooling
of the engine and the lubrication of rear suspension components.
Avoid prolonged driving on such surfaces.

used in this guide are explained as follows:
