SAFETY INFORMATION
AN VEHICLE IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE. A vehicle handles
differently from other vehicles including motorcycles and cars. A collision or rollover can occur
quickly, even during routine maneuvers such as turning and riding on hills or over obstacles, if you fail
to take proper precautions. SEVERE INJURY OR DEATH can result if you do not follow these
instructions:
Read this manual and all labels carefully and follow the operating procedures described.
Never operate a vehicle without proper training or instruction. Take a Training Course. Beginners
should receive training from a certified instructor. Contact an authorized vehicle dealer.
Always follow the age recommendation:
A child under 16 years old should never operate a vehicle with engine size greater than 90cc.
Never allow a child under age 16 to operate a vehicle without adult supervision, and never allow
continued use of a vehicle by a child if he or she does not have the abilities to operate it safely.
Never carry more than 1 passenger on a vehicle.
Always avoid operating a vehicle on any paved surfaces, including sidewalks, driveways, parking
lots and streets.
Never operate a vehicle on any public street, road or highway, even dirt or gravel one.
Never operate a vehicle without wearing an approved motorcycle helmet that fits properly for you
and passenger. You should also wear eye protection (goggles or face shield), gloves, boots, a
long-sleeved shirt or a jacket, and long pants.
Never consume alcohol or drugs before or while operating this vehicle.
Never operate at speeds too fast for your skills or the conditions. Always go at a speed that is
proper for the terrain, visibility, operating conditions, and your experience.
Never attempt wheelies, jumps, or other stunts.

Always inspect your vehicle each time you use it to make sure it is in safe operating condition.
Always follow the inspection and maintenance procedures and schedules described in this manual.
Always keep both hands on the handlebars and both feet on the footboards of the vehicle during
operation.
Always go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the vehicle.
Never operate on excessively rough, slippery or loose terrain until you have learned and practiced
the skills necessary to control the vehicle on such terrain. Always be especially cautious on these kinds
of terrain.
Always follow proper procedures for turning as described in this manual. Practice turning at low
speeds before attempting to turn at faster speeds. Do not turn at excessive speed.
Never operate the vehicle on hills too steep for the vehicle or for your abilities. Practice on
smaller hills before attempting larger hills.
Always follow proper procedures for climbing hills as described in this manual. Check the terrain
carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces.
Shift your weight forward. Never open the throttle suddenly. Never go over the top of a hill at high
speed.
Always follow proper procedures for going down hills and for braking on hills as described in this
manual. Check the terrain carefully before you start down any hill. Shift your weight backward. Never
go down a hill at high speed. Avoid going down a hill at an angle that would cause the vehicle to lean
sharply to one side. Go straight down the hill where possible.

hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the vehicle.

Always check for obstacles before operating in a new area. Never attempt to operate over large
obstacles, such as large rocks or fallen trees. Always follow proper procedures when operating over
obstacles as described in this manual.
Always be careful when skidding or sliding. Learn to safely control skidding or sliding by
practicing at low speed and on level, smooth terrain. On extremely slippery surfaces, such as ice, go
slowly and be very cautious in order to reduce the chance of skidding or sliding out of control.
Never operate an vehicle in fast flowing water or in water deeper than that recommended in this
manual. Remember that wet brakes may have reduced stopping ability. Test your brakes after leaving
water. If necessary, apply those several times to let friction dry out the linings.
Always be sure there are no obstacles or people behind you when you operate in reverse. When it
is safe to proceed in reverse, go slowly.
Always use the size and type of tires specified in this manual.
Always maintain proper tire pressure as described in this manual.
Never modify a vehicle through improper installation or use of accessories.
Never exceed the stated load capacity for an vehicle. Cargo should be properly distributed and
securely attached. Reduce speed and follow instructions in this manual for carrying cargo or pulling a
trailer. Allow greater distance for braking.
