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.
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:

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.

SLIDING AND SKIDDING
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.

WHAT TO DO IF ...
This section is designed to be a reference guide
only. Be sure to read each section on riding tech-
niques completely.
WHAT TO DO ...

If your ATV doesn’t turn when you want it to:
Bring the ATV to a stop and practice the turning
maneuvers again. Be sure you are putting your
weight on the footboard to the outside of the
turn. Position your weight over the front wheels
for better control. (See pages 7-39–7-43.)


If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If nec-
essary, gradually let off the throttle and/or steer to
the outside of the turn. (See pages 7-39–7-43.)


If your ATV starts to slide sideways:
Steer in the direction of the slide if you have the
room. Applying the brakes or accelerating is
not recommended until you have corrected the
slide. (See pages 7-71–7-73.)

If your ATV can’t make it up a hill you are trying
to climb:
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side
of the ATV and physically turn the ATV around.
If the ATV starts to slip backwards DO NOT
USE THE REAR BRAKE - the ATV may tip
over on top of you. Dismount the ATV on the
uphill side. (See pages 7-45–7-53.)


If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned to-
wards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that the
ATV is going to tip over, dismount on the uphill
side. (See pages 7-59–7-61.)
