SAFETY INFORMATION
SAFETY INFORMATION
EBU27255AN ATV IS NOT A TOY AND CAN BE HAZARD-OUS TO OPERATE.An ATV handles differently from other vehicles, in-
cluding motorcycles and cars. A collision or roll-
over can occur quickly, even during routine
maneuvers such as turning and riding on hills or
over obstacles, if you fail to take proper precau-
tions.
SEVERE INJURY OR DEATH can result if you do
not follow these instructions:
Read this manual and all labels carefully and fol-
low the operating procedures described.
 Never operate an ATV without proper training or
instruction. Take a training course. Beginners
should receive training from a certified instruc-
tor. Contact an authorized ATV dealer to find
out about the training courses nearest you.
 Always follow the age recommendation:
– A child under 16 years old should never oper-
ate an ATV with engine size greater than 90 cc. 
Never allow a child under age 16 to operate an
ATV without adult supervision, and never allow
continued use of an ATV by a child if he or she
does not have the abilities to operate it safely.
 Never carry a passenger on an ATV.
 This vehicle is intended for off-road use only. Do
not operate on any paved surfaces such as:
sidewalks, driveways, parking lots, paved
roads, public streets or other motorway.
 Watch carefully for other vehicles when operat-
ing on unpaved public streets or roads. Make
sure you know your country’s laws and regula-
tions before you ride on unpaved public streets
or roads.
 Never operate an ATV without wearing an ap-
proved motorcycle helmet that fits properly.
You should also wear eye protection (goggles
or face shield), gloves, boots, a long-sleeved
shirt or a jacket, and long pants.

in an accident:

Approved motorcycle helmet that fits properly
 Eye protection (goggles, helmet face shield, or
protective eyewear)
 Over-the-ankle boots, gloves, long-sleeved
shirt or jacket, and long pants
An approved helmet and other personal protective
equipment can reduce the severity of injuries in an

proved motorcycle helmet increases your
chances of a severe head injury or death in the
event of an accident.

reduce the risk of a serious accident or injury. Eye
protection, such as a face shield or goggles, may
reduce the risk of foreign material getting in your
eyes and help prevent loss of vision. WARNING!
Operating without eye protection can result in
an accident and increases your chances of a
severe injury in the event of an accident.[EWB02612]
