8The 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
carefully.
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
without verifying that you have regained proper braking ability. WARNING! Wet brakes may have
reduced stopping ability, which could cause
loss of control.
[EWB02622]
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 and the V-belt cooling
duct check hose. Also, remove the V-belt case
drain plug to drain any water that may have accu-
mulated.
NOTICE: Undrained water can cause
damage or improper operation.
[ECB00842]
Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.

RIDING OVER ROUGH TERRAIN
WARNING
EWB01652Riding 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
caution. Look out for obstacles which could cause
damage to the ATV or could lead to an upset or

12. Pour the recommended coolant into the radi-
ator until it is full, and then install the radiator
cap.
13. Start the engine, let it idle for several minutes, and then turn it off.
TIPWhile the engine is idling, check the cooling sys-
tem for leaks. 14. When the engine is cool, remove the radiatorcap to check the coolant level in the radiator.
If it is low, add sufficient coolant until it reach-
es the top of the radiator, and then install the
radiator cap.
15. Install the panels and the front carrier.EBU37113Cleaning the air filterThe main air filter element and sub air filter ele-
ment should be cleaned every 20–40 hours of en-
gine operation. When servicing the air filter
elements, check the air filter case inlet for obstruc-
tions. Check the air filter case rubber joint to the
throttle body and the rubber joint manifold fittings
for an air-tight seal. Tighten all fittings securely to
avoid the possibility of unfiltered air entering the
engine.
TIP Replace the air filter elements if damaged.
Service the air filter more frequently if you often
ride in wet or dusty areas.
There is a check hose at the bottom of the air fil-
ter case. If dust or water collects in this hose,
empty the hose and clean the air filter case and
air filter elements. 1. Park the ATV on a level surface.
2. Remove the seat. (See page 5-18.)
3. Remove the air filter case cover by unhooking
the air filter case cover holders.1. Air filter case check hose

5. Pull off the lock plate from the main air filter
assembly, and then remove the air filter ele-
ment (sponge material) from the frame.
6. Wash the air filter elements gently but thor- oughly with YAMALUBE Air Filter Cleaner, or
a dedicated parts cleaning solvent.
WARNING! Always use parts cleaning sol- vent. Never use low-flash-point solvents
or gasoline because the engine could
catch fire or explode.
[EWB01943]
7. Squeeze out the excess moisture, and let dry. NOTICE: Do not twist the sponge material
when squeezing it.
[ECB00442]
8. Check the air filter elements (sponge material) for damage, replace if necessary.
9. Apply YAMALUBE Foam Air Filter Oil (or equivalent) to the air filter elements.TIPThe sponge material should be wet but not drip-
ping. 10. Install the sub air filter element.
11. Install the main air filter element onto its frame, then the lock plate, and then install the
main air filter assembly.

912. Install the air filter case cover by hooking the
holders onto the cover. NOTICE: Make sure
that the air filter element is properly seated
in the air filter case. Never operate the en-
gine with the air filter element removed.
Doing so would allow unfiltered air to enter
the engine, causing rapid engine wear and
possible engine damage. Additionally, the
fuel injection system would be affected re-
sulting in poor engine performance and
possible overheating.
[ECB00763]
13. Install the seat.EBU28905Cleaning the spark arresterBe sure the exhaust pipe and muffler are cool be-
fore cleaning the spark arrester.
WARNING
EWB02342Always let the exhaust system cool prior to
touching exhaust components.
Do not start the engine with the spark arrester
removed. Sparks or exhaust particulate can
cause eye injury, burns, or start a fire. 1. Remove the tailpipe bolts.
2. Remove the tailpipe by pulling it out of the muffler, and then remove the gasket.1. Gasket
