7 The ATV can be used to cross slow moving, shal-
low water of up to a maximum of 35 cm (14 in) in
depth. Before entering the water, choose your path
carefully. Enter where there is no sharp drop off,
and avoid rocks or other obstacles which may be
slippery or upset the ATV. Drive slowly and care-
fully.
Test your brakes after leaving the water. If neces-
sary, apply them several times to let friction dry out
the linings. Do not continue to ride your ATV with-
out verifying that you have regained proper brakingability. WARNING! Wet brakes may have re-
duced stopping ability, which could cause loss
of control.
[EWB02621]
After riding your ATV in water, be sure to drain the
trapped water by removing the check hose at the
bottom of the air filter case, the drive select lever
box check hose, and the storage compartment
check hose. NOTICE: Undrained water can
cause damage or improper operation.
[ECB00841]
Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.

the footboards at all times. Avoid jumping the ATV
as loss of control and damage to the ATV may re-
sult.
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.U1P066E0.book Page 21 Thursday, August 5, 2010 4:15 PM

7With practice, over a period of time, skill at con-
trolled sliding can be developed. The terrain
should be chosen carefully before attempting such
maneuvers, since both stability and control are re-
duced. Bear in mind that sliding maneuvers should
always be avoided on extremely slippery surfaces
such as ice, since all control may be lost.
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 page 7-12.)
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 page 7-12.)
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 page 7-21.)
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 page 7-14.)

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 page 7-17.)
If your ATV encounters shallow water:
Ride slowly and carefully through slow moving
water, watching for obstacles. Be sure to let wa-
ter drain from the ATV and CHECK YOUR
BRAKES FOR PROPER OPERATION when
you come out of the water. Do not continue to
ride your ATV until you have regained adequate
braking ability. (See page 7-18.)

EBU24071Adjusting the drive select lever safety
system cable The drive select lever safety system cable stretch-
es with use, which can result in improper function.
Therefore, the safety system cable should be
checked and adjusted by a Yamaha dealer at the
intervals specified in the periodic maintenance and
lubrication chart.EBU29601Brakes Replacement of brake components requires pro-
fessional knowledge. Brake service should be per-
formed by a Yamaha dealer.
WARNING
EWB02571Operating with improperly serviced or adjust-
ed brakes could lead to a loss in braking ability
and an accident.EBU24120Checking the front brake pads and rear
brake shoes The front brake pads and the rear brake shoes
must be checked for wear at the intervals specified
in the periodic maintenance and lubrication chart.
EBU24171Front brake pads
Check each front brake pad for damage and mea-
sure the lining thickness. If a brake pad is dam-
aged or if the lining thickness is less than 1.0 mm
(0.04 in), have a Yamaha dealer replace the brake
pads as a set.TIPThe wheels need to be removed to check the
brake pads. (See page 8-46.)1. Brake pad

CLEANING AND STORAGE
EBU25881Cleaning Frequent, thorough cleaning of your ATV will not
only enhance its appearance but will improve its
general performance and extend the useful life of
many components.
1. Before cleaning the ATV:
a. Block off the end of the exhaust pipe to
prevent water entry. A plastic bag and
strong rubber band may be used.
b. Make sure the spark plug and all filler caps
are properly installed.
2. If the engine case is excessively greasy, apply
degreaser with a paint brush. Do not apply de-
greaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden
hose. Use only enough pressure to do the job.
WARNING! Wet brakes may have reduced
stopping ability, increasing the chance of
an accident. Test the brakes after washing.
Apply the brakes several times at slow
speeds to let friction dry out the linings.
[EWB02311]
NOTICE: Excessive water pressure
may cause water seepage and deteriora-tion of wheel bearings, brakes, transmis-
sion seals and electrical devices. Many
expensive repair bills have resulted from
improper high-pressure detergent applica-
tions such as those available in coin-oper-
ated car washers.
[ECB00711]
4. Once most of the dirt has been hosed off,
wash all surfaces with warm water and mild,
detergent-type soap. An old toothbrush or bot-
tle brush is handy for hard-to-reach places.
5. Rinse the ATV off immediately with clean wa-
ter and dry all surfaces with a chamois, clean
towel or soft absorbing cloth.
6. Clean the seat with a vinyl upholstery cleaner
to keep the cover pliable and glossy.
7. Automotive type wax may be applied to all
painted and chrome plated surfaces. Avoid
combination cleaner-waxes. Many contain
abrasives which may mar the paint or protec-
tive finish. When finished cleaning, start the
engine and let it idle for several minutes.
