2technique described in this manual on level
ground. Avoid crossing the side of a steep hill if
possible.
Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stall-
ing, use the proper gear range and maintain a
steady speed when climbing a hill. If you stall or
roll backwards, follow the special procedure for
braking described in this manual. Dismount on
the uphill side or to a side if pointed straight up-
hill. Turn the ATV around and remount, following
the procedure described in this manual.
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 obsta-
cles as described in this manual.
Always be careful when skidding or sliding.
Learn to safely control skidding or sliding by
practicing at low speeds 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 ATV 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 them 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 de-
scribed in this manual.
Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow in-
structions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.
Do not operate your ATV during darkness un-
less it is equipped with a properly functioning
headlight. Off-road riding is inherently danger-
ous and additionally, off-road trails do not have
streetlights to guide you.

6sold by Yamaha or modifications not specifically
recommended by Yamaha, even if sold and in-
stalled by a Yamaha dealer.
Aftermarket parts, accessories, and modifica-
tions
While you may find aftermarket products similar in
design and quality to genuine Yamaha Accesso-
ries, recognize that some aftermarket accessories
or modifications are not suitable because of po-
tential safety hazards to you or others. Installing
aftermarket products or having other modifica-
tions performed to your ATV that change any of
the vehicle’s design or operation characteristics
can put you and others at greater risk of serious
injury or death. You are responsible for injuries re-
lated to changes in the vehicle.
Keep the following in mind when considering an
accessory or operating an ATV which has acces-
sories.
Accessories should be rigidly and securely
mounted. An accessory which can shift position
or come off while you are riding could affect
your ability to control the ATV.
Do not mount an accessory where it could inter-
fere with your ability to control the ATV. Exam-
ples include (but are not limited to) a heavy or bulky object attached to the handlebars which
could make steering difficult, an accessory that
limits your ability to move around on the seat, or
one that limits your view.
Use extra caution when riding an ATV with ac-
cessories. The ATV may handle differently than
it does without accessories.
EBU21043Loading
WARNING
EWB00821Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and se-
curely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking. Cargo or a trailer can change the stability and han-
dling of an ATV.
You must use common sense and good judgment
when carrying cargo or towing a trailer. Keep the
following points in mind:

Never exceed the weight limits shown. An over-
loaded ATV can be unstable.
Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath-
room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad-
just the load in the trailer, if necessary, to reduce the weight on the hitch. If you are carrying cargo
and towing a trailer, include the tongue weight
in the maximum ATV load limit.
Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
Make sure the load does not interfere with con-
trols or your ability to see where you are going.
Ride more slowly than you would without a
load. The more weight you carry, the slower you
should go. Although conditions vary, it is good
practice not to exceed low range whenever you
are carrying heavier loads or when towing a
trailer.
Allow more braking distance. A heavier ATV
takes longer to stop.
Avoid making sharp turns unless at very slow
speeds.
Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.

go, accessories, and tongue):240.0 kg (530 lb)
