7 CROSSING A SLOPE
WARNING
EWB01632Improperly crossing hills or turning on hills
could cause loss of control or cause the ATV to
overturn.
Always follow proper procedures as de-
scribed in the Owner’s Manual.
Avoid hills with excessively slippery or loose
surfaces.
Avoid crossing the side of a steep hill.
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 tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning
on any hill.Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting
to cross a sloping surface. Avoid slopes with slip-
pery surfaces or rough terrain that may upset your
balance.As you travel across a slope, lean your body in the
uphill direction. It may be necessary to correct the
steering when riding on loose surfaces by pointing
the front wheels slightly uphill. When riding on
slopes, be sure not to make sharp turns either up
or down hill.
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.U18P64E0.book Page 18 Thursday, May 13, 2010 6:00 PM

7cident. Be sure to keep your feet firmly mounted on
the footrests at all times. Avoid jumping the ATV as
loss of control and damage to the ATV may result.
SLIDING AND SKIDDING
WARNING
EWB01662Skidding or sliding improperly may cause you
to lose control of this ATV. You may also re-
gain traction unexpectedly, which may cause
the ATV to overturn.
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
control.Care should be used when riding on loose or slip-
pery surfaces since the ATV may slide. If unex-
pected and uncorrected, sliding could lead to an
accident.
To reduce the tendency for the front wheels to slide
in loose or slippery conditions, positioning your
weight over the front wheels will sometimes help.If the rear wheels of your ATV start to slide side-
ways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the slide.U18P64E0.book Page 21 Thursday, May 13, 2010 6:00 PM
