Failure to heed 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.
Purchasers of a new Polaris ATV and their eligible family members are
entitled to take the ATV RiderCoursesm. Contact ATV Enrollment Express at
[phone] or visit www.atvsafety.org for information on enrollment in the
ATV RiderCoursesm.
• This vehicle is an ADULT VEHICLE ONLY. Operation is prohibited for anyone
under 16 years of age.
• 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. When you purchased
your new ATV, your dealer instructed you on the authorized ATV
RiderCoursesm available to you and your eligible family members. This
training is included in the purchase price of your ATV. Polaris strongly
encourages you and your eligible family members who will be riding
the ATV to take the ATV RiderCoursesm. You were also provided with
printed materials that explain safe operating procedures. You should
review this information on a regular basis.
If you purchased a used Polaris ATV, you can take the ATV
RiderCoursesm by calling ATV Enrollment Express at [phone] or
by visiting www.atvsafety.org. Purchasers of a used Polaris ATV will be
charged for this training.
A Polaris ATV is an off-road vehicle. Familiarize yourself with all laws
and regulations concerning the operation of this vehicle in your area.
We strongly advise you to strictly follow the recommended maintenance
program outlined in your owner's manual. This preventive maintenance
program is designed to ensure that all critical components on your vehi-
cle are thoroughly inspected at specific intervals.

Eye Protection
Do not depend on eyeglasses or sunglasses for eye protection. When-
ever 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 sturdy over-the-calf boots with low heels.
Clothing
Always wear long sleeves and long pants to protect arms and legs.
Riding pants with kneepads and a jersey with shoulder pads provide the
best protection.
Equipment Modifications
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.
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, including (but not limited to) mow-
ers, blades, tires, sprayers, or large racks, may change the handling char-
acteristics of the vehicle. Use only Polaris-approved accessories, and
familiarize yourself with their function and effect on the vehicle.
