PAY ATTENTION TO YOUR SAFETY
This section presents some of the most important information and
recommendations to help you ride your UTV safely. Please read these pages. This
section also includes information about the location of safety labels on your UTV.
Important safety information
Your UTV can provide many years of service and fun if you take responsibility
for your own safety, others around you, and understand the challenges you can
meet while riding. Throughout this owner’s manual, you will find many helpful
recommendations to protect yourself and others while riding. The following are
some we consider most important.
Follow the age recommendation
The minimum recommended age of this UTV model is 16 years. Anyone under the
age of 16 are NOT permitted to operate this vehicle.
Always wear a helmet
It is a proven fact that helmets significantly reduce the number and severity of head
injuries and or death. So always wear protective head gear while operating this
vehicle! We also recommend wearing protective boots, gloves, and other protective
gear.

- 12 -
Off-road use only
Your UTV is designed for OFF-ROAD use only. The tires are not made for
pavement, and the UTV does not meet the specifications required for use on public
roads.
Take time to learn & practice
Even if you have ridden other UTVs, take the time to become familiar with your
skills and get accustomed to the size and weight of this vehicle.
Because many accidents involve inexperienced or untrained riders, we recommend
all riders to take a training course approved by the UTV safety institute.
Contact an authorized UTV dealer to find out about training courses near you.
Be alert for off-road hazards
The terrain can present a variety of challenges when you ride off-road. Continually
“read” the terrain for unexpected turns, drop-offs, rocks, ruts, and other hazards.
Always keep your speed low enough to allow time to see and react to hazards.

- 13 -
Ride within your limits
Pushing the limits is another major cause of UTV accidents. Never attempt to ride
beyond your personal abilities or faster than conditions warrant.
Don’t drink and ride
Drinking and riding can also cause potentially fatal accidents. Do not operate this
vehicle if you have consumed any alcohol. Just one drink can prohibit you from
reacting in enough time to your changing surroundings.
Keep your UTV maintained
It is important to keep your UTV properly maintained and in safe riding condition. To
help avoid having a breakdown, inspect your vehicle before each ride and keep it
maintained. This unit comes with labels and a hangtag containing important safety
information. Make sure anyone who rides this vehicle reads, and fully understands
its contents before riding. These labels should be considered permanent parts of
this UTV. If one comes off or becomes hard to read, contact an authorized dealer to
have them replaced.

- 14 -
TIPS FOR SAFE DRIVING
1．Reduce speed when approaching any turns, hills, or bends. Once you have fully
turned, gradually increase speed.
2．Be careful when passing any vehicle in front of you.
3．Check the brakes each time you ride to ensure they have not been cut during
off-road riding or are too soft for full stopping capabilities.
4. During riding, the vibration can loosen the bolts. Before each ride, take time to
inspect that all bolts are tightened.
For training please call ASI at 1-800-887-2887
