7The ATV can be used to cross slow moving, shal-
low water of up to a maximum of 20 cm (8 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. Also, remove the V-belt
case drain screw to drain any water that may have
accumulated. 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.

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.

then pull the sponge material off from the air
filter element frame.
6. Wash the sponge material gently but thor-
oughly in solvent. WARNING! Always use

material and let it dry. NOTICE: Do not twist
the sponge material when squeezing it.
[ECB00441]
8. Check the sponge material and replace it if
damaged.
9. Apply Yamaha foam air filter oil or other qual-
ity foam air filter oil to the sponge material.TIPThe sponge material should be wet but not drip-
ping.10. Pull the sponge material over the air filter ele-
ment frame.11. Install the washer and screw. NOTICE: Be
sure to install the washer with its curved
side facing outward as shown.
[ECB00453]
12. Install the air filter element into the air filter
case. NOTICE: Make sure that the air filter
element is properly seated in the air filter
case. Never operate the engine with the air
filter element removed. This will allow un-
filtered air to enter the engine, causing rap-
id engine wear and possible engine
damage. Additionally, operation without
the air filter element will affect carburetor
jetting with subsequent poor performance
and possible engine overheating.

TIPThe air filter element should be cleaned every 20–
40 hours. It should be cleaned and lubricated more
often if the ATV is operated in extremely dusty ar-
eas. Each time the air filter element maintenance
is performed, check the air inlet of the air filter case
for obstructions. Check the air filter case rubber
joint to the carburetor fittings and the rubber joint
manifold fittings for an air-tight seal. Tighten all fit-
tings securely to avoid the possibility of unfiltered
air entering the engine.V-belt case air filter element
