mended engine oil, and then insert the dip-
stick completely into the oil filler hole.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down.NOTICEECB00300●In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of
a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II” or higher.
●Make sure that no foreign material enters the
crankcase.12. Start the engine, and then let it idle for severalminutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
13. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.
14. Install the access cover by turning it clock- wise.EBU27306Final gear oil The final gear case must be checked for oil leak-
age before each ride. If any leakage is found, have
a Yamaha dealer check and repair the ATV. In ad-
dition, the final gear oil level must be checked and
the oil changed as follows at the intervals specified
in the periodic maintenance and lubrication chart.
To check the final gear oil level1. Place the ATV on a level surface.
Recommended oil:
See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.00 L (2.11 US qt, 1.76 Imp.qt)

2. Remove the final gear oil level check bolt and
its gasket, and then check the oil level in the
final gear case. The oil level should be at the
brim of the check hole.
3. If the oil is below the brim of the check hole, remove the final gear oil filler bolt and its gas-
ket, and then add sufficient oil of the recom-
mended type to raise it to the correct level. 4. Check the gaskets for damage, and replace
them if necessary.

8To change the final gear oil
1. Place the ATV on a level surface.
2. Place an oil pan under the final gear case to collect the used oil.
3. Remove the final gear oil filler bolt, the final gear oil level check bolt, the final gear oil drain
bolt and their gasket to drain the oil from the
final gear case.
4. Install the drain bolt and its new gasket, and then tighten the bolt to the specified torque. 5. Refill with the recommended final gear oil to
the brim of the check hole as shown. NOTICE:
Be sure no foreign material enters the final
gear case.

EBU23426Differential gear oil The differential gear case must be checked for oil
leakage before each ride. If any leakage is found,
have a Yamaha dealer check and repair the ATV.
In addition, the differential gear oil level must be
checked and the oil changed as follows at the in-
tervals specified in the periodic maintenance and
lubrication chart. To check the differential gear oil level
1. Place the ATV on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil level in the
differential gear case. The oil level should be
at the brim of the filler hole.
3. If the oil is below the brim of the filler hole, add sufficient oil of the recommended type to raise
it to the correct level.
4. Check the gasket for damage, and replace it if necessary.

6. Wash the sponge material gently, but thor-
oughly, in solvent. WARNING! Always use
parts cleaning solvent to clean the sponge
material. Never use low-flash-point sol-
vents or gasoline to clean the sponge ma-
terial because the engine could catch fire
or explode.
[EWB01941]
7. Squeeze the excess solvent out of the sponge 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. Install the mesh and the sponge material 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 unfiltered air to enter the engine,
causing rapid engine wear and possible
engine damage. Additionally, operation
without the air filter element will affect the
fuel injection system with subsequent
poor performance and possible engine
overheating.
[ECB00761]
11. Insert the projections on the air filter case cov- er into the holders on the air filter case, and
then install the air filter case cover by hooking
the holders onto the cover.

●Use only the specified brake fluid; otherwise,
the rubber seals may deteriorate, causing
leakage.●Refill with the same type of brake fluid. Add-
ing a brake fluid other than DOT 4 may result
in a harmful chemical reaction.●Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of
the fluid and may result in vapor lock.NOTICEECB01160Brake fluid may damage painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.As the brake pads wear, it is normal for the brake
fluid level to gradually go down. A low brake fluid
level may indicate worn brake pads and/or brake
system leakage; therefore, be sure to check the
brake pads for wear and the brake system for leak-
age. If the brake fluid level goes down suddenly,
have a Yamaha dealer check the cause before fur-
ther riding.
EBU24292Changing the brake fluid Have a Yamaha dealer change the brake fluid at
the intervals specified in the periodic maintenance
and lubrication chart. In addition, have the oil seals
of the master cylinders and calipers as well as the
brake hoses replaced at the intervals listed below
or whenever they are damaged or leaking.●Oil seals: Replace every two years.●Brake hoses: Replace every four years.EBU27772Checking the front and rear brake lever
free play The front and rear brake lever free play must be
checked at the intervals specified in the periodic
maintenance and lubrication chart. The brake le-
vers should have no free play as shown. If there is
free play, have a Yamaha dealer check the brake
system.
