1 hill. If you stall or roll backwards, follow the spe-
cial procedure for braking described in this man-
ual. Dismount on the uphill side or to a side if
pointed straight uphill. 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 re-
duce the chance of skidding or sliding out of con-
trol.
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 modify an ATV through improper installa-
tion or use of accessories.
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. Al-
low greater distance for braking.
WARNING
EWB00060
Always turn off the engine when refueling.
Do not refuel right after the engine has been
running and is still very hot.
Do not spill gasoline on the engine or ex-
haust pipe/muffler when refueling. Never re-
fuel while smoking, or in the vicinity of
sparks, open flames, or other sources of ig-
nition such as the pilot lights of water heat-
ers and clothes dryers. Gasoline can catch
fire and you could be burned.

The speedometer unit is equipped with the follow-
ing:
a speedometer (which shows the riding speed)
an odometer (which shows the total distance
traveled)
a tripmeter (which shows the distance traveled
since it was last set to zero)
Odometer and tripmeter modes
Pushing the “SELECT” button switches the display
between the odometer mode “ODO” and the trip-
meter mode “TRIP” in the following order:
ODO → TRIP → ODO
To reset the tripmeter, select it by pushing the “SE-
LECT” button, and then push the “SELECT” button
for at least two seconds. The tripmeter can be used
to estimate the distance that can be traveled with a
full tank of fuel. This information will enable you to
plan future fuel stops.
NOTE:Pushing in the “SELECT” button, then turning the
key to “ON”, and keeping them in this position for
at least two seconds switches the display between“mph” and “km/h”.
