CROSSING A SLOPE
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 slippery surfaces or rough ter-
rain that may upset your balance.
As you travel across a slope, lean your body in
the uphill direction. It may be necessary to cor-
rect 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 bal-
ance, gradually steer again in the direction you
wish to travel.
w
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:
8Always follow proper procedures as
described in the Owner’s Manual.
8Avoid hills with excessively slippery or
loose surfaces.
8Shift your weight to the uphill side of the
ATV.
OK

SLIDING AND SKIDDING
Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected 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.

This section is designed to be a reference guide
only. Be sure to read each section on riding
techniques completely.
WHAT TO DO ...
8If your ATV doesn’t turn when you want it to:
Bring the ATV to a stop and practice the turn-
ing 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 7-41–
7-45.)
8If your ATV begins to tip while turning:
Lean more into the turn to regain balance. If
necessary, gradually let off the throttle and/or
steer to the outside of the turn. (See pages
7-41–7-45.)

8If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards 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 7-61–7-63.)
8If your ATV encounters shallow water:
Ride slowly and carefully through slow mov-
ing water, watching for obstacles. Be sure to
let water drain from the ATV and CHECK
YOUR BRAKES FOR PROPER OPERATION
when you come out of the water. Do not con-
tinue to ride your ATV until you have regained
adequate braking ability. (See pages 7-65–
7-67.)

Drive chain slack check
NOTE:
Move the ATV back and forth and find the tight-
est position of the drive chain. Check and/or
adjust the chain slack while it is in this tightest
position.
To check the drive chain slack, all tires must be
touching the ground and there should be no
weight on it. Check the drive chain slack at the
position shown in the illustration Normal slack is
approximately 15–20 mm. If the slack exceeds
20 mm , adjust it to specification.
