TURNING YOUR ATV
To achieve maximum traction while riding off-
road, the two rear wheels are mounted solidly
on one axle and turn together at the same
speed. Therefore, unless the wheel on the in-
side of the turn is allowed to slip or lose some
traction, the ATV will resist turning. A special
turning technique must be used to allow the
ATV to make turns quickly and easily. It is es-
sential that this skill be learned first at low
speed.
WARNING
Always follow proper procedures for turning
as described in this Owner’s Manual. Practice
turning at low speeds before attempting to
turn at faster speeds. Do not turn at speedstoo fast for your skills or the conditions.

CLIMBING UPHILL
Use proper riding techniques to avoid vehicle
overturns on hills. Be sure that you can maneu-
ver your ATV well on flat ground before at-
tempting any incline and then practice riding
first on gentle slopes. Try more difficult climbs
only after you have developed your skill. In all
cases avoid inclines with slippery or loose sur-
faces, or obstacles that might cause you to lose
control.
WARNING
Never operate the ATV on hills too steep for
the ATV or for your abilities. The vehicle can
overturn more easily on extremely steep hills
than on level surfaces or small hills. Practiceon smaller hills before attempting large hills.
It is important when climbing a hill to make
sure that your weight is transferred forward on
the ATV. This can be accomplished by leaning
forward and, on steeper inclines, standing on
the footboards and leaning forward over the
handlebars.

EL
If you are climbing a hill and you find that you
have not properly judged your ability to make
it to the top, you should turn the ATV around
while you still have forward motion (provided
you have the room to do so) and go down the
hill.
WARNING
Never attempt to turn the ATV around on any
hill until you have mastered the turning tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning on
any hill. Avoid crossing the side of a steep hill
if possible.
When crossing the side of a hill:l
Always follow proper procedures as de-
scribed in the Owner’s Manual.
l
Avoid hills with excessively slippery or
loose surfaces.
l
Shift your weight to the uphill side of theATV.

WARNING
Use proper gear and maintain steady speed
when climbing a hill.
If you lose all forward speed:l
Keep weight uphill.
l
Apply the brakes.
l
Shift into the parking position, after you
are stopped.
If you begin rolling backwards:
l
Keep weight uphill.
l
2WD: Never apply the rear brake while
rolling backwards. Apply the front brake.
4WD: Apply both front and rear brakes
gradually.
When fully stopped, shift into the parking
position.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and re-
mount, following the procedure described in
the Owner’s Manual.

EL
Whenever possible, ride your ATV straight
downhill. Avoid sharp angles which could al-
low the ATV to tip or roll over. Carefully choose
your path and ride no faster than you will be
able to react to obstacles which may appear.
WARNING
Always follow proper procedures for going
down hills as described in this Owner’s Manu-
al.
Note: a special technique is required when
braking as you go down a hill.l
Always check the terrain carefully before
you start down any hill.
l
Shift your weight backward.
l
Never go down a hill at high speed.
l
Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side. Go straight down the hill wherepossible.

If your ATV does begin to tip over, gradually
steer in the downhill direction if there are no
obstacles in your path. As you regain proper
balance, gradually steer again in the direction
you wish to travel.

hill until you have mastered the turning tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning on
any hill. Avoid crossing the side of a steep hill

CROSSING THROUGH SHALLOW WATER
The ATV can be used to cross slow moving,
shallow water of up to a maximum of 35 cm in
depth. Before entering the water, choose your
path carefully. Enter where there is no sharp
drop off, and avoid rocks or other obstacles
which may be slippery or upset the ATV. Drive
slowly and carefully.
WARNING
Never operate this ATV in fast flowing water
or in water deeper than that specified in your
Owner’s 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. If the ATV is operated through deep or
fast flowing water, the tires may float, causing
loss of traction and loss of control, whichcould lead to an accident.

RIDING OVER ROUGH TERRAIN
Riding over rough terrain should be done with
caution. Look out for obstacles which could
cause damage to the ATV or could lead to an
upset or accident. Be sure to keep your feet
firmly mounted on the footboards at all times.
Avoid jumping the ATV as loss of control and
damage to the ATV may result.
WARNING
Before operating in a new area, check for ob-
stacles. Never attempt to ride over large ob-
stacles, such as large rocks or fallen trees.
When you go over obstacles, always follow
proper procedures as described in the Owner’sManual.
