2004 YAMAHA BEAR TRACKER 250 Start

7-53
If your ATV has stalled or stopped and you believe
you can continue up the hill, restart carefully to
make sure you do not lift the front wheels which
could cause you to lose control. If you are unable
to continue up the hill, dismount the ATV on the
uphill side. Physically turn the ATV around and
then descend the hill.
If you start to roll backwards, DO NOT use the rear
brake to stop or try to put the ATV in gear. The
ATV could easily tip over backwards. Instead, dis-
mount the ATV immediately on the uphill side.

WARNING
_ Always follow proper procedures for going
down hills as described in this Owner’s
Manual.
Note: a special technique is required when
braking as you go down a hill.

Always check the terrain carefully before
you start down any hill.


Shift your weight backward.


Never go down a hill at high speed.


Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side.
Go straight down the hill where possible.

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 7-41–7-45.)


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
7-41–7-45.)


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 7-47–7-55.)


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 7-61–7-63.)
