WHAT TO DO IF...
This section is designed to be a reference
guide only. Be sure to read each section on
riding techniques 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
necessary, 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 7-69 ~ 7-71.)

If your ATV can’t make it up a hill you are
trying to climb:
Turn the ATV around if you still have for-
ward 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. Dis-
mount the ATV on the uphill side. (See pag-
es 7-45 ~ 7-53.)
If your ATV is traversing a sloping surface:
Be sure to ride with your weight positioned
towards the uphill side of the ATV to main-
tain 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 dis-
cover that the ATV is going to tip over, dis-
mount on the uphill side. (See pages 7-59 ~
7-61.)
