WELCOME
Dear Parents:
We believe your children should have the opportunity to enjoy the
snowmobile riding experience along with you. We've provided this
owner's manual to assist you and your children in learning about the safe
operation and care of your new POLARIS snowmobile. Please review
the information in this manual with any child who may operate the
snowmobile. Help your children learn to operate the snowmobile with
safety as a top priority. Help them also learn to show respect for our
environment and for the rights of others while operating the
snowmobile. Since the operator will be a newcomer to the exciting
winter sport of snowmobiling, please be sure he/she understands this
information before riding the snowmobile. Never allow a child to
operate the snowmobile without adult supervision.
This owner's manual contains instructions for minor maintenance, but
major repairs are covered in the POLARIS Service Manual and should
be performed by a factory certified Master Service Dealer®(MSD)
technician. 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
snowmobile are thoroughly inspected at various intervals. If you have
any questions about the snowmobile, contact a POLARIS dealer for
assistance. See page 82 for the part numbers of POLARIS products.

WELCOME
Dear Children:
Before you ride your new POLARIS snowmobile, there are some
important things that you need to know. Your parents and POLARIS
want you to enjoy riding your new snowmobile, and that's why you need
to read and understand the information in your owner's manual.
Ask your parents to explain anything you don't understand, and pay
close attention to the warnings and instructions you read. 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. So read your manual, and
then enjoy riding your new POLARIS snowmobile!

INTRODUCTION
Important Notes for Owners and Drivers
After reading this manual, store it in the snowmobile for convenient
reference. 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.
TIP:The illustrations and photos used in this manual are general
representations. 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.

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
standard-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
topics. We will continue to participate in this type of study so that
someday we may find the answers to these difficult issues.

INTRODUCTION
Preservation of the Environment
Environmental Protection
As part of the continuing environmental education campaign, we are
encouraging state and provincial governments across the snowbelt to
adopt rigorous safety training programs which also encourage
protection of our environment, wildlife and vegetation. Snowmobile
clubs and other organizations are working together to protect our
environment. It is very important that we encourage them as well as
become actively involved ourselves.
• Protect and preserve your right to ride by joining your local trail
riding clubs.
• Teach your child the importance of respecting our snowmobiles as
well as the environment in which we ride.
