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
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.

7RIDING 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 lar-
ge 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

11. Pour the recommended coolant into the res-
ervoir to the maximum level mark, and then
install the reservoir cap. NOTICE: Mix anti-
freeze with distilled water only. However, if
distilled water is not available, soft water
may be used for refilling. Do not use hard
water or salt water since they are harmful
to the engine.
[ECB00992]
12. Pour the recommended coolant into the radi- ator until it is full.
13. Install the radiator cap, start the engine, let it idle for several minutes, and then turn it off. 14. Remove the radiator cap to check the coolant
level in the radiator. If it is low, add sufficient
coolant until it reaches the top of the radiator,
and then install the radiator cap.
15. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 16. Install the panels and the front carrier.EBU37112Cleaning 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.
Antifreeze/water mixture ratio:
1:1
Recommended antifreeze: High-quality ethylene glycol antifreeze con-
taining corrosion inhibitors for aluminum
engines
Coolant quantity: Radiator (including all routes):1.32 L (1.40 US qt, 1.16 Imp.qt)
Coolant reservoir (up to the maximum level
mark): 0.25 L (0.26 US qt, 0.22 Imp.qt)

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. Place the ATV on a level surface.
2. Remove the seat. (See page 4-13.)
3. Remove the air filter case cover by unhooking
the air filter case cover holders. 4. Pull out the main air filter assembly and sub
air filter element.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.
