TIPBe sure to wipe off spilled oil on any parts af-
ter the engine and exhaust system have
cooled down. NOTICEECB00301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 la-
beled “ENERGY CONSERVING II” or
higher. 
Make sure that no foreign material en-
ters the crankcase.
12. Start the engine, and then let it idle for
several minutes 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 10 minu-
tes, and then check the oil level and cor-
rect it if necessary.
14. Install the right rear panel by installing the
bolts and the quick fastener screws.
15. Lower the cargo bed.EBU36050Final gear oilCheck the oil level and change the final gear
oil at the intervals specified in the general
maintenance and lubrication chart.
Checking the final gear oil level 1. Park the vehicle on a level surface.
Recommended engine oil: See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.20 L (2.33 US qt, 1.94 Imp.qt)
With oil filter cartridge replacement: 2.30 L (2.43 US qt, 2.02 Imp.qt)

8. Wash the sponge material gently butthoroughly in parts cleaning solvent.
WARNING! Using gasoline or other flammable solvents to clean the air fil-
ter element can cause a fire or explo-
sion, which could lead to serious
injury.
[EWB03360]
9. Squeeze the excess solvent out of the
sponge material. NOTICE: Do not twist
the sponge material when squeezing
it.
[ECB00442]
10. Wash the sponge material in warm soapy
water to remove remaining solvent, then
rinse thoroughly with plain warm water.
11. Squeeze excess water out of the sponge
material. NOTICE: Do not twist the
sponge material when squeezing it.
[ECB00442]
12. Allow the sponge material to dry thor- oughly. Inspect the sponge material and
replace it if damaged.

EBU32440V-belt case drain plugThe V-belt case drain plug is located under
the cargo bed. (See page 4-22 for cargo bed
lifting and lowering procedures.)
After riding in water deep enough to allow wa-
ter to enter the V-belt case, remove the drain
plug to drain any water from the case.
If water drains from the V-belt case after re-
moving the drain plug, have a Yamaha dealer
inspect the vehicle, as the water may affect
other engine parts.
EBU32450Cleaning the spark arrester
WARNING
EWB03370Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the en-
gine is stopped and the exhaust system is
cool before cleaning the spark arrester. Do
not start the engine while cleaning the ex-
haust system. 1. Remove the tailpipe bolts.

WARNING
EWB02721Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:
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; other-
wise, the rubber seals may deteriorate,
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. Wa-
ter will significantly lower the boiling
point of the fluid and may result in vapor
lock.
NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.
1. Minimum level markSpecified brake fluid: DOT 4

EBU32550Brake light switch adjustmentThe brake light switch, which is activated by
the brake pedal, is properly adjusted when
the brake light comes on just before braking
takes effect. If necessary, adjust the brake
light switch as follows.
Turn the adjusting nut while holding the brake
light switch in place. To make the brake light
come on earlier, turn the adjusting nut in di-
rection (a). To make the brake light come on
later, turn the adjusting nut in direction (b).
EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-
place damaged cables. Corrosion can
result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked. Lubricate the cable ends. If the cables do not
operate smoothly, ask a Yamaha dealer to re-
place them.EBU32570Brake pedal and accelerator pedal lu-

The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your vehicle. Use only
genuine Yamaha parts on your vehicle. Imita-
tion parts may look like Yamaha parts, but
they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.
WARNING
EWB03450When checking the fuel system, do not
smoke and make sure there are no open
flames or sparks in the area, including pilot
lights from water heaters or furnaces.
Gasoline or gasoline vapors can ignite or
explode, causing severe injury or property
damage. UB427BE0.book Page 55 Friday, February 5, 2016 2:14 PM

4. Put the frame on stands or blocks to raiseall wheels off the ground.
5. Tie a plastic bag over the exhaust pipe outlet to prevent moisture from entering.
6. If storing in a humid or salt-air atmo-
sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat covers.
7. Remove the battery and charge it. Store it in a dry place and recharge it once a
month. Do not store the battery in an ex-
cessively warm or cold place [less than 0
°C (30 °F) or more than 30 °C (90 °F)].
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha
dealer if the fuel system needs to be drained.
