WARNING
EWB01640Never operate this ATV in fast flowing water or
in water deeper than that specified in your
Owner’s Manual. Remember that wet brakes
may have reduced stopping ability. Test your
brakes after leaving water. If necessary, apply
them several times to let friction dry out the lin-
ings. If the ATV is operated through deep or
fast flowing water, the tires may float, causing
loss of traction and loss of control, whichcould lead to an accident.Test your brakes after leaving the water. Do not
continue to ride your ATV without verifying that you
have regained proper braking ability.
NOTICEECB00840After riding your ATV in water, be sure to drain
the trapped water by removing the check hos-
es at the bottom of the air filter case. Also, re-
move the drain plugs from the front and rear
storage compartments and the V-belt case to
drain any water that may have accumulated.
Wash the ATV with fresh water if it has beenoperated in salt water or muddy conditions.

7 RIDING OVER ROUGH TERRAIN
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.
WARNING
EWB01650Before operating in a new area, check for ob-
stacles. Never attempt to ride over large obsta-
cles, such as large rocks or fallen trees. Whenyou go over obstacles, always follow proper
procedures as described in the Owner’s Manu-
al.
SLIDING AND SKIDDING
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.

16. Loosen the clamp screw, and then remove the
V-belt cooling duct.
17. Loosen the cylinder head air bleed bolt, with-
out removing it, to allow all of the air to escape
from the air bleed bolt hole.18. When coolant begins to flow out of the bolt
hole, tighten the cylinder head air bleed bolt to
the specified torque.
19. Start the engine and let it idle for ten minutes.
20. Rev the engine five times.
21. Pour the recommended coolant into the radia-
tor until it is full. Tightening torque:

822. Stop the engine and allow it to cool. If the cool-
ant level has dropped after the engine has
cooled, add sufficient coolant until it reaches
the top of the radiator, and then install the ra-
diator cap.
23. Start the engine, and then check for coolant
leakage.
TIPIf any leakage is found, have a Yamaha dealercheck the cooling system.
24. Install the V-belt cooling duct, and then tighten
the clamp screw.
25. Install the panels.EBU27804Cleaning the air filter element The air filter element should be cleaned at the in-
tervals specified in the periodic maintenance and
lubrication chart. Clean or, if necessary, replace
the air filter element more frequently if you are
riding in unusually wet or dusty areas.TIPThere are two check hoses at the bottom of the air
filter case, which are located behind panels D and
E. (See page 8-8 for an explanation on removingthe panels.) Check the hoses periodically and, if
dust or water collects in them, empty them and
clean the air filter element and air filter case.1. Air filter case check hose

WARNING
EWB02380Never run the engine in an enclosed area when
purging the spark arrester, otherwise it could
cause injury to the eyes, burns, carbon monox-
ide poisoning, possibly leading to death, and
start a fire.Always let the exhaust system cool prior to
touching exhaust components.Always wear eye protection, and make sure
no one is behind the ATV.Make sure there are no combustible materi-als in the area.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 asthe water may affect other engine parts.
EBU24045Adjusting the throttle cable free play The throttle cable free play should be checked
and, if necessary, adjusted at the intervals speci-
fied in the periodic maintenance and lubrication
chart.
The throttle cable free play should measure 3.0–
5.0 mm (0.12–0.20 in) at the throttle lever. Period-
ically check the throttle cable free play and, if nec-
essary, adjust it as follows.1. V-belt case drain plug
