Record your snowmobile's identification numbers and key number in
the spaces provided. Remove the spare key and store it in a safe place.
Your key can be duplicated only by mating a Polaris key blank with one
of your existing keys, so if both keys are lost, the ignition switch must
be replaced.

Important Notes for Owners and Drivers
After reading this manual, store it in the snowmobile for convenient ref-
erence. It should remain with the snowmobile when the snowmobile is
sold.
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.

INTRODUCTION
Preservation of the Environment
Polaris is committed to supporting an environmental education cam-
paign. We encourage governments to adopt rigorous safety training pro-
grams that encourage protection of our environment, including wildlife
and vegetation.
Snowmobile clubs and other organizations are working together to pro-
tect 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 lev-
els 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 74
of this manual to ensure that all critical components on the snowmobile
are thoroughly inspected by your dealer at specific mileage intervals.
WARNING
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.
