INTRODUCTION
Important Notes for Owners and Drivers
After reading this manual, store it in the snowmobile (if possible) for
convenient reference. It should remain with the snowmobile when the
snowmobile is sold.
Some of the illustrations and photos used in this manual are general
representations. Your model may differ.
Follow the maintenance program outlined in this manual. Preventive
maintenance ensures that critical components of the snowmobile are
inspected by your dealer at specific mileage intervals.
You and your dealer must complete the registration form included with
your snowmobile and forward it to us. This completed form is necessary
to ensure warranty coverage.
Protect and preserve your right to ride by joining your local trail riding
clubs.
When teaching inexperienced operators to ride, set up a predetermined
course for practice. Make sure they know how to drive and control the
snowmobile before allowing them to make longer trips. Teach them
proper snowmobile courtesy, and enroll them in driver’s training and
safety courses sponsored by local or state organizations.

INTRODUCTION
Preservation of the Environment
POLARIS is committed to supporting an environmental education
campaign. We encourage state and provincial governments across the
snowbelt to adopt rigorous safety training programs that encourage
protection of our environment, including wildlife and vegetation.
Snowmobile clubs and other organizations are working together to
protect our environment. Please support their efforts and operate your
snowmobile with consideration for the protection and preservation of
our environment.
Noise Level
One of the most publicized issues about snowmobiles is noise. The
Society of Automotive Engineers (SAE), the standard-setting body for
snowmobile development, recommends that snowmobiles conform to
prescribed sound levels.
POLARIS snowmobiles are engineered to conform to these SAE
standards. Our muffler systems are designed to reduce noise levels and
must not be altered or removed. The sound of your snowmobile may not
be welcome to non-snowmobilers, so you have a responsibility to
operate your snowmobile with concern for others. We do our part by
manufacturing quieter machines; we ask your help to further reduce the
impact of noise by operating your snowmobile safely and responsibly.
Air Pollution
POLARIS engineers continuously investigate ways to reduce emission
levels of two-stroke engines. We expect our efforts to lead to the
reduction of potential air pollution.
In addition to our technological research, we encourage government
agencies, manufacturers, distributors, dealers, ecologists, and other
interested parties to work together to develop data on environmental
topics.

SAFETY
Operator Safety
Follow the recommended maintenance program beginning on page 64
of this manual to ensure that all critical components on the snowmobile
are thoroughly inspected by your dealer at specific mileage intervals.
Driving a snowmobile requires your full attention. DO NOT drink alcohol or use
drugs or medications before or while driving or riding as a passenger. They will
reduce your alertness and slow your reaction time.
Snowmobiles are capable of traveling at high speeds. Use extra caution to
ensure operator safety. Make sure your snowmobile is in excellent operating
condition at all times. Always check major and vital safety components before
every ride.
All POLARIS snowmobiles are designed and tested to provide safe operation
when used as directed. Failure of critical machine components may result from
operation with any modifications, especially those that increase speed or power.
DO NOT MODIFY YOUR MACHINE. The snowmobile may become
aerodynamically unstable at speeds higher than those for which it is designed.
Loss of control may occur at higher speeds. Modifications may also create a
safety hazard and lead to bodily injury.
The warranty on your entire machine is terminated if any equipment has been
added, or any modifications have been made, to increase the speed or power of
the snowmobile.
