Welcome
Dear Children:
Before you ride your new Polaris ATV, there are some important things that you need to
know. You must learn how to keep yourself and those around you safe while you're riding.
Your parents and Polaris want you to enjoy riding your new ATV, and that's why you need to
read and understand the information in your owner's manual. You must also take an ATV
training course before you begin riding.
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. Never drive your ATV alone. Always make sure an adult is
watching you when you ride.
Drive safely and enjoy riding your new Polaris ATV!

Introduction
Failure to follow the warnings and safety precautions contained in this manual can result in severe
injury or death. A Polaris ATV is not a toy and can be hazardous to operate. This vehicle handles
differently than other vehicles, such as motorcycles and cars. A collision or rollover can occur quickly,
even during routine maneuvers like turning, or driving on hills or over obstacles, if you fail to take
proper precautions.
• Read this owner’s manual. Understand all
safety warnings, precautions and operating
procedures before operating a Polaris ATV.
Keep this manual with the ATV.
• Never operate an ATV without proper
instruction. Take a training course.
• Always follow the age guidelines for your
vehicle. 90cc models are not designed for
children age 12 and under. 50cc models are
designed for children not less than 6 years of
age. No child under the age of 16 should ride
any ATV designed and sold for an adult.
• Never permit a guest to operate the ATV
unless the guest has read this manual and all
product labels and has completed a certified
safety training course.

Safety Training
ATV safety training is a top priority for
Polaris. Polaris strongly encourages you and
any family members who will be riding the
ATV to take a training course.
If you purchased a new Polaris ATV in the
United States, your dealer provided
instruction to you about the authorized ATV
RiderCoursesm that is available to you and
your eligible family members. This training
is included in the purchase price of your
ATV.
In addition, you were provided with printed
material and a video or DVD that instructs
operators on safe operating procedures. You
should review this information with your
child on a regular basis. Do not allow other
children to ride this ATV unless they have
read the manual, seen the instructional
video or DVD and taken and completed an
approved ATV safety training course.

Safety
Riding Gear
Always wear clothing suited to the type of riding. ATV
riding requires special protective clothing for comfort
and to reduce the chance of injury.
Helmet
Wearing a helmet can prevent a severe head injury.
Whenever riding a Polaris vehicle, always wear a helmet
that meets or exceeds established safety standards.
Approved helmets in the USA and Canada bear a U.S.
Department of Transportation (DOT) label.
Approved helmets in Europe, Asia and Oceania bear the
ECE 22.05 label. The ECE mark consists of a circle sur-
rounding the letter E, followed by the distinguishing
number of the country which has granted approval. The
approval number and serial number will also be dis-
played on the label.

Eye Protection
Do not depend on eyeglasses or sunglasses for eye protection. Whenever riding a Polaris
vehicle, always wear shatterproof goggles or use a shatterproof helmet face shield. Polaris
recommends wearing approved Personal Protective Equipment (PPE) bearing markings such
as VESC 8, V-8, Z87.1, or CE. Make sure protective eye wear is kept clean.
Gloves
Off-road style gloves with knuckle pads are the best for comfort and protection.
Boots
The best footwear is a pair of strong over-the-calf boots with low heels.
Clothing
Always wear long sleeves and long pants to protect arms and legs. Riding pants with knee-
pads and a jersey with shoulder pads provide the best protection.

Safety
Equipment Modifications
We are concerned for the safety of our customers and for the general public. Therefore, we
strongly recommend that consumers do not install on a Polaris ATV any equipment that may
increase the speed or power of the vehicle, or make any other modifications to the vehicle for
these purposes. Any modifications to the original equipment of the vehicle create a substan-
tial safety hazard and increase the risk of bodily injury.
The warranty on your Polaris ATV 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.
The addition of certain accessories may change the handling characteristics of the ATV. Use
only Polaris-approved accessories, and familiarize yourself with their function and effect on
the ATV.

Safety Warnings
Failure to Inspect Before Operating
Failure to inspect and verify that the ATV is in
safe operating condition before operating
increases the risk of an accident. Always inspect
the ATV before each use to make sure it's in safe
operating condition. Always follow all inspection
and maintenance procedures and schedules
described in the owner's manual.
Protective Apparel
Operating this ATV
without wearing an
approved helmet
increases the risk of
a serious head
injury in the event of
an accident.
Operating without
eye protection could
result in an accident
and could increase
the chance of a
serious injury in the
event of an accident.
Always wear an approved helmet that fits
properly. Always wear eye protection (goggles or
face shield), gloves, boots, a long-sleeved shirt
or jacket and long pants.

17
Safety
Safety Warnings
Carrying a Passenger
Carrying a passenger greatly reduces the
operator's ability to balance and control the ATV,
which may result in an accident or overturn.
Never carry a passenger on this ATV.
Using Alcohol or Drugs
Operating the ATV after consuming alcohol or
drugs could adversely affect operator judgment,
reaction time, balance and perception. Never
consume alcohol or drugs before or while
operating an ATV.
