Always follow proper procedures for turn-
ing as described in this manual. Practice
turning at low speeds before attempting to
turn at faster speeds. Do not turn at exces-
sive speed.


Never operate the ATV on hills too steep for
the ATV or for your abilities. Practice on
smaller hills before attempting larger hills.


Always follow proper procedures for climb-
ing hills as described in this manual. Check
the terrain carefully before you start up any
hill. Never climb hills with excessively slip-
pery or loose surfaces. Shift your weight
forward. Never open the throttle suddenly
or make sudden gear changes. 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 de-
scribed 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.


Always follow proper procedures for cross-
ing the side of a hill as described in this
manual. Avoid hills with excessively slip-
pery or loose surfaces. Shift your weight to
the uphill side of the ATV. Never attempt to
turn the ATV around on any hill until you
have mastered the turning technique de-
scribed in this manual on level ground.
Avoid crossing the side of a steep hill if pos-
sible.

Never exceed the weight limits shown. An
overloaded ATV can be unstable.
Load cargo on the carriers as close to the
center of the vehicle as possible. Put cargo
at the rear of the front carrier and at the
front of the rear carrier. Center the load
from side to side.
Tie down cargo securely to the carriers.
Make sure cargo in the trailer cannot move
around. A shifting load can cause an acci-
dent.
Make sure the load does not interfere with
controls or your ability to see where you are
going. MAXIMUM LOADING LIMIT
Vehicle loading limit (total weight of
rider, cargo and accessories):
100 kg

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 2nd gear
whenever you are carrying heavier loads or
when towing a trailer.
Allow more braking distance. A heavier ve-
hicle takes longer to stop.
Avoid making sharp turns unless at very
slow speeds.
Avoid hills and rough terrain. Choose ter-
rain carefully. Added weight affects the sta-
bility and handling of the ATV.
WARNING
Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
vehicle handling which could lead to an acci-
dent. Cargo should be properly distributed
and securely attached. Reduce speed when
carrying cargo or pulling a trailer. Allow great-
er distance for braking.

As you approach a curve, slow down and begin
to turn the handlebars in the desired direction.
As you do so, put your weight on the footboard
to the outside of the turn (opposite your desired
direction) and lean your upper body into the
turn. Use the throttle to maintain an even speed
through the turn. This maneuver will let the
wheel on the inside of the turn slip slightly, al-
lowing the ATV to make the turn properly.
This procedure should be practiced at slow
speed many times in a large off-road area with
no obstacles. If an incorrect technique is used,
your ATV may continue to go straight. If the
ATV doesn’t turn, come to a stop and then
practice the procedure again. If the riding sur-
face is slippery or loose, it may help to position
more of your weight over the front wheels by
moving forward on the seat. Once you have
learned this technique you should be able to
perform it at higher speeds or in tighter curves.
1. Lean towards inside of turn.
2. Support your weight on the outer footrest.
1. Se pencher vers l’intérieur du virage.
2. Faire reposer son poids sur le repose-pied extérieur.
1. Inclínese hacia el interior del giro.
2. Descanse su peso en el descansapie externo.

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.
WARNING
Always follow proper procedures for
climbing hills as described in this Owner’s
Manual.
Always check the terrain carefully before
you start up any hill.
Never climb hills with excessively slip-
pery or loose surfaces.
Shift your weight forward.
Never open the throttle suddenly or make
sudden gear changes. The ATV could flip
over backwards.
Never go over the top of any hill at high
speed. An obstacle, a sharp drop, or an-
other vehicle or person could be on the
other side of the hill.

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 possi-
ble.
When crossing the side of a hill:
Always follow proper procedures as de-
scribed in the Owner’s Manual.
Avoid hills with excessively slippery or
loose surfaces.
Shift your weight to the uphill side of the
ATV.
