5B410012Engine oil and oil filter cartridge
Check engine oil level before each operation.
In addition, change the oil and the oil filter car-
tridge at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level1. Park the vehicle on a level surface.
2. Remove the console. (See page 8-9 for console removal and installation proce-
dures.)
3. Check the engine oil level on a cold en-
gine. TIPIf the engine was started before checking the
oil level, be sure to warm up the engine suffi-
ciently, and then wait at least 10 minutes until
the oil settles for an accurate reading.4. Remove the engine oil dipstick, and thenwipe it off with a clean rag.

5. Insert the dipstick completely into the oilfiller hole, and then remove it again to
check the oil level. TIPThe engine oil should be between the mini-
mum and maximum level marks.1. Maximum level mark 2. Minimum level mark6. If the engine oil is at or below the mini-mum level mark, add sufficient oil of the
recommended type to raise it to the cor-
rect level. 7. Insert the dipstick completely into the oil
filler hole.
8. Install the console.

NOTICE●
In order to prevent clutch slippage
(since the engine oil also lubricates
the clutch), do not mix any chemical
additives with oil. 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 “EN-
ERGY CONSERVING II” or higher.
●
Make sure that no foreign material en-
ters the crankcase.
13. Start the engine, and then let it idle forseveral minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
14. Turn the engine off, wait at least 10 min- utes, and then check the oil level and cor-
rect it if necessary.
15. Install the console.
5B410013Final gear oil
Checking the final gear oil level 1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its O-ring, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole.1. Final gear oil filler bolt 2. O-ring

3. Place an oil pan under the final gear caseto collect the used oil.
4. Remove the final gear oil filler bolt and its
O-ring, the final gear oil drain bolt and its
gasket to drain the oil.1. Final gear oil drain bolt 2. Gasket5. Install the drain bolt and its new gasket,and then tighten the bolt to the specified
torque. 6. Refill with the recommended final gear oil
up to the brim of the filler hole. NOTICE:
Be sure no foreign material enters the
final gear case.
7. Install the oil filler bolt and its new O-ring, and then tighten the bolt to the specified
torque.
8. Check for oil leakage. If oil leakage is found, check for the cause.

tightening the bolts to the specified
torque.
5B410014Differential gear oil
Checking the differential gear oil level1. Park the vehicle on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil lev-
el. It should be up to the brim of the filler
hole.
3. If the level is low, add sufficient oil of the
recommended type to raise it to the spec-
ified level. NOTICE: Be sure no foreign
material enters the differential gear
case.

WARNING
Improper maintenance can result in loss of
braking ability. Observe these precautions:●
Insufficient brake fluid may allow air to
enter the brake system, reducing brak-
ing performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid; oth-
erwise, the rubber seals may deterio-
rate, causing leakage.
●
Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
●
Be careful that water does not enter
the brake fluid reservoir when refilling.
Water will significantly lower the boil-
ing point of the fluid and may result in
vapor lock.
NOTICEBrake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.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 leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EVU00860Brake fluid replacement
Complete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.●
Replace the oil seals every two years.
●
Replace the brake hoses every four years.
