assist you and your children in learning about the safe operation and
care of your new Polaris snowmobile. Please review the information in

major repairs are covered in the Polaris Service Manual and should be
performed by a Factory Certified MSD (Master Service Dealer) Techni-
cian. Be sure to return to your dealership for all of your service needs
during, and after, the warranty period.
The preventive maintenance program outlined in this manual is
designed to ensure that all critical components on your child's snowmo-
bile are thoroughly inspected at various intervals. If you have any ques-
tions about the snowmobile, contact a Polaris dealer for assistance. See

INTRODUCTION
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.
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.
NOTE: The illustrations and photos used in this manual are general represen-
tations. Your model may differ.
PARENTS: Do not allow anyone under the age of six (6) to operate this
machine. Review the information in this manual with any child who
may be operating the snowmobile. It is up to you to teach any operator
the proper and safe way to ride a snowmobile. You must set boundaries
and adhere to them, keeping the operator's safety foremost in your mind.
Never allow a child to operate this machine without adult supervision.
These units are not designed for adult use. Serious damage to the vehicle
may occur if the maximum rider weight capacity is exceeded. Never
exceed the maximum rider weight capacity. See page 80.
CHILDREN: Before you ride your new Polaris snowmobile, there are
some important things that you need to know. Your safety and the safety
of others is the most important thing to think about at all times. As the
driver of the snowmobile, you must learn how to keep yourself and
those around you safe while you're riding.
Pay attention when you see this symbol:
IMPORTANT
Parents should sit down with their children and read the Youth Section with
them before allowing them to use this snowmobile. Parents must also read the
Adult Section before allowing their children to ride this snowmobile.
This is the safety alert symbol. When you see this symbol on your
snowmobile or in this manual it means PAY ATTENTION because you
could die or be seriously hurt if you don't follow the instructions.

INTRODUCTION
Preservation of the Environment
Teach your child to drive their snowmobile with consideration for the
protection and preservation of the environment.
Noise
One of the most publicized subjects with regard to snowmobiles is
noise. The Society of Automotive Engineers (SAE), which is the stan-
dard-setting body for snowmobiles, has recommended that snowmobiles
conform to prescribed sound levels. This Polaris snowmobile has been
engineered to conform to these SAE standards.
In order to be meaningful, all regulations require the cooperation of the
snowmobile owner. Muffling systems, designed to reduce noise levels,
should not be altered or removed. Snowmobile drivers must be aware
that they have a public responsibility to operate their snowmobiles with
concern for others. As a snowmobile operator you may not realize the
sound of your snowmobile may annoy non-snowmobilers. We are
attempting to do our part through the manufacture of quieter machines,
and we also ask your help in the effort to further reduce the impact of
noise.
Air Pollution
As a part of Polaris' plan for the snowmobile's compatibility within the
environment, our engineers are investigating ways to reduce emission
levels of engines. We expect our efforts to lead to the reduction of
potential air pollution.
The four-stroke engine used in this snowmobile produces less exhaust
emissions and reduces noise, as well.
In addition to technological research, we also suggest that governmental
agencies, manufacturers, distributors, dealers, ecologists, and other
interested parties work together to develop data on environmental top-
ics. We will continue to participate in this type of study so that someday
we may find the answers to these difficult issues.
