7The 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 V-belt cooling duct
check hose, the drive select lever box check hose
and the storage compartment check hose. Also,
remove the V-belt case drain plug to drain any wa-
ter that may have accumulated. NOTICE: Und-
rained 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.

7RIDING OVER ROUGH TERRAIN
WARNING
EWB01651Riding improperly over obstacles could cause
loss of control or a collision. Before operating
in a new area, check for obstacles. Never at-
tempt to ride over large obstacles, such as
large rocks or fallen trees. When you go over
obstacles, always follow proper procedures as
described in the Owner’s Manual.Riding over rough terrain should be done with cau-
tion. Look out for obstacles which could cause
damage to the ATV or could lead to an upset or ac-cident. Be sure to keep your feet firmly mounted on
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.

ing, possibly leading to death, and start a fire.

EBU23930V-belt case drain plug After riding in water deep enough to allow it to en-
ter the V-belt case, remove this plug to drain the
water from the case.TIPIf water drains from the V-belt case after removing
the plug, have a Yamaha dealer check the ATV as
the water may affect other engine parts.
EBU23940Adjusting the carburetor The carburetor should be checked and, if neces-
sary, adjusted at the intervals specified in the peri-
odic maintenance and lubrication chart. The
carburetor is an important part of the engine and
requires very sophisticated adjustment. Therefore,
most carburetor adjustments should be left to a
Yamaha dealer, who has the necessary profes-
sional knowledge and experience. The adjustment
described in the following section, however, may
be performed by the owner as part of routine main-
tenance.NOTICEECB00480The carburetor has been set and extensively
tested at the Yamaha factory. Changing these
settings without sufficient technical knowl-
edge may result in poor performance of or
damage to the engine.EBU24000Adjusting the engine idling speed The engine idling speed must be checked and, if
necessary, adjusted as follows at the intervals
specified in the periodic maintenance and lubrica-
tion chart.
