INTRODUCTION
Preservation of the Environment
Teach your child to drive their snowmobile with consideration for the
protection and preservation of the environment.
Noise Level
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. Teach your child the following:
Respect your snowmobile;
respect your environment;
and you will earn
the respect of everyone.

INTRODUCTION
Vehicle Identification Numbers
The frame vehicle identification number (VIN) and engine serial
number are important for model identification when registering your
vehicle, when obtaining insurance, and when ordering replacement
parts. In the event your vehicle is stolen, these numbers are essential to
the recovery and identification of your vehicle.
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. If both keys are lost, the ignition switch must be
replaced. See your Polaris dealer.
Please record your snowmobile identification numbers below for future
reference:
1. Tunnel VIN (lower right side of the tunnel)
________________________________________________________________
2. Engine Serial Number (right front side of engine crankcase)

SAFETY
WARNING
Failure to follow the warnings in this manual can result in severe
injury or death. Read and understand the owner’s manual and all
warnings before operating a Polaris snowmobile. Adults must
thoroughly explain this information to all operators of the
snowmobile.
All operators must be at least six (6) years old and must
understand the risk involved if these important warnings and
cautions are not heeded.
Equipment Modifications
All Polaris snowmobiles have been designed and tested to provide safe
operation when used as directed. Failure of critical machine
components may result from operation with any modification;
especially those that increase speed or power. There’s a significant
possibility of loss of control at higher speeds.
We are concerned for the safety of our customers and for the general
public. Any modifications to the original equipment of the vehicle
create a substantial safety hazard and increase the risk of bodily injury.
Therefore, we strongly recommend that consumers do not install on a
Polaris snowmobile any equipment that may increase the speed or
power of the vehicle, or make any other modifications to the vehicle
for these purposes.
The warranty on your Polaris snowmobile is terminated if any
equipment has been added to the vehicle, or if any modifications have
been made to the vehicle, that increase its speed or power.

SAFETY
Maintenance Program

safety. Particular caution must be taken to make sure that the
snowmobile is in excellent operating condition at all times. We
strongly recommend that the operator, as well as an adult, check major
and vital safety components before each use of the vehicle.
We also recommend that you strictly follow the maintenance schedule
outlined in this manual to ensure that all critical components on the
snowmobile are thoroughly inspected by your dealer at various mileage
intervals.
This snowmobile is not a toy. It is a well-engineered and
well-constructed recreational vehicle. The information in this manual
is provided to aid you in its safe operation.

SAFETY
Safety Decals
Safety and warning decals have been placed on the vehicle for the
operator’s protection. Make sure the operator understands the
information on all decals. If any decal becomes illegible or comes off,
contact your Polaris dealer for a replacement. Any safety decal
needing replacement will be provided by Polaris at no charge. The part
number is printed on the decal.
CAUTION
Improper use of this snowmobile or failure to maintain it in good
operating condition can result in injury. To reduce this possibility,

YOUTH SECTION
Know Your Snowmobile
Before you have an adult start the engine for you for the first time, let’s
learn about the controls on your new machine.
1. Engine Stop Switch - When the engine is running, you can push
this button down and the engine will stop. The stop switch must
be in the UP position to start the engine again.
2. Throttle Control - The throttle control makes your snowmobile go
forward when you press it with your thumb. You must always
make sure the throttle control does not stick before you operate
your snowmobile. Read more about it on page 19.
3. Recoil Starter Handle - Pull the recoil starter handle to start your
snowmobile. An adult will help you start it the first time.
4. Choke Knob - You may need to use the choke to help start your
snowmobile if the engine is cold. Read more about it on page 48.
Always have an adult put gas in your snowmobile. Never try to do
it yourself.
5. Gas Cap - The gas cap has to be taken off when an adult puts gas in
your snowmobile. Never take the gas cap off. Always make sure
it’s tightly closed.

YOUTH SECTION
Know Your Snowmobile
Always take your thumb off the throttle lever when you squeeze
the brake lever.
6. Brake Lever - Squeeze the brake lever toward the handlebar to
make your snowmobile slow down or stop.
7. Ignition Switch - The ignition switch key must be turned ON
before pulling on the recoil starter handle to start your snowmobile.
You can also use this key to turn off the engine.
Never ride without the tether strap attached to your right wrist and
to your snowmobile. Be careful not to let the cord get tangled
around the handlebars or any part of your body.
8. Tether Strap/Switch - The tether strap must always be attached
snugly to your right wrist and to your snowmobile every time you
drive. If you fall off your snowmobile, the tether strap will pull away
from the switch and the engine will stop.
Always make sure the hood hold-down straps are latched before
you ride.
9. Hood Hold-Down Strap - There are two straps to hold down the
hood of your snowmobile. They must always be latched before you
start your machine.

YOUTH SECTION
Know Your Snowmobile
1. Hood - The hood covers the moving and hot parts of the engine
and must be securely latched before you ride the snowmobile.
2. Headlight - The headlight is always on when the engine is
running. It helps others see you when you’re riding during
daylight, but it’s not supposed to be strong enough to help you see
in the dark. Drive your snowmobile only in the daylight.
3. Windshield - Always keep your windshield clean so you can see
where you’re driving.
4. Handlebar - The handlebar is connected to the skis. When you
turn the handlebar, the skis turn in the same direction.
5. Flag - The flag helps other people see where you’re riding. Your
snowmobile is smaller than an adult snowmobile, so it’s harder to
see. Never remove the flag from your snowmobile.
6. Seat and Storage - When the engine isn’t running, you can take
the seat cushion off and put things under the seat in the special
compartment.
7. Taillight - The taillight is always on when the engine is running.
It will help others see you when you’re riding.
8. Snow Flap - The snow flap keeps snow, ice or other things from
flying out behind your snowmobile.
Never get close to a moving track. Never wear clothing that
could get caught in a moving track, like a long scarf or baggy
clothing. Tie up long hair.
9. Track - The engine makes the track turn. The turning track makes
your snowmobile go forward.
10. Skis - The skis turn your snowmobile in the same direction that
you turn the handlebar.
