TIP●
Some maintenance items need more frequent service if you are riding in unusually wet, dusty,
sandy or muddy areas, or at full throttle.
●
Hydraulic brake service
Regularly check and, if necessary, correct the brake fluid level.
Every two years replace the internal components of the brake master cylinder and calipers, and change the brake fluid.
Replace the brake hoses every four years and if cracked or damaged.Rear upper and lower
knuckle pivots* Lubricate with lithium-soap-based grease.Drive shaft universal joint*
Lubricate with lithium-soap-based grease.Engine mount* Check for cracks or damage.
Check bolt tightness.Front and rear axle boots*
Check for cracks or other damage, and replace if necessary.Fittings and fasteners* Check all chassis fittings and fasteners.
Correct if necessary.

5B410012Engine oil and oil filter cartridgeCheck 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. Lift the cargo bed up. (See page 4-26 for cargo bed lifting and lowering 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.
1. Engine oil dipstick

Changing the coolant
The coolant must be changed by a Yamaha
dealer at the intervals specified in the periodic
maintenance and lubrication chart.
Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant, have a Yamaha deal-
er check the antifreeze content of the coolant
as soon as possible.
The radiator fan is automatically switched on
or off according to the coolant temperature in
the radiator.NOTICEMix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling.If your vehicle overheats, see page 8-57 for
instructions.
EVU00740Axle bootsCheck the axle boots for holes or tears.
If any damage is found, have them replaced
by a Yamaha dealer.1. Front axle boot (× 2 each side)

5B410016Cleaning the air filter elementThe air filter element should be cleaned every
20–40 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.NOTICENever operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, op-
eration without the air filter element will af-
fect the fuel injection system with
subsequent poor performance and possi-
ble engine overheating.
1. Remove the center passenger seat cush-
ion. (See page 4-18 for seat cushion re-
moval and installation procedures.)
2. Remove the air filter case cover by un- hooking the holders.1. Air filter case cover holder ( × 5)

WARNING
Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:●
Insufficient brake fluid may allow air
to enter the brake system, reducing
braking performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid;
otherwise, the rubber seals may dete-
riorate, causing leakage.
●
Refill with the same type of brake flu-
id. Adding a brake fluid other than
DOT 4 may result in a harmful chemi-
cal reaction.
●
Be careful that water does not enter
the brake fluid reservoir when refill-
ing. Water will significantly lower the
boiling point of the fluid and may re-
sult 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 replacementComplete 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.

cracks or damage at the intervals specified in
the periodic maintenance and lubrication
chart.
Have a Yamaha dealer replace the stabilizer
bushes if necessary.
