EBU31731Front and rear brakesBrake pedal
Check that there is no free play in the brake
pedal. If there is free play, have a Yamaha
dealer check the brake system. (See page
8-41.)
 Check the operation of the brake pedal. It
should move smoothly and there should be
a firm feeling when the brakes are applied.
If not, have the vehicle inspected by a
Yamaha dealer.
Brake fluid level
Check the brake fluid level. Add fluid if neces-
sary. (See page 8-39.) Brake fluid leakage
Check to see if any brake fluid is leaking out
of the pipe joints or the brake fluid reservoir.
Apply the brakes firmly for one minute. If there
is any leakage, have the vehicle inspected by
a Yamaha dealer.
Brake operation
Check the operation of the brakes at the start
of every drive. Test the brakes at slow speed
after starting out to make sure they are work-
ing properly. If the brakes do not provide
proper braking performance, inspect the
brake system. (See page 8-38.)
EBU33200FuelMake sure there is suffi
cient fuel in the tank.
Specified brake fluid: DOT 4

WARNING
EWB02522Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and ex-
plosions and to reduce the risk of injury
when refueling, follow these instructions. 1. Before refueling, turn off the engine andbe sure that no one is sitting in the vehi-
cle.
Never refuel while smoking, or while in
the vicinity of sparks, open flames, or
other sources of ignition such as the pilot
lights of water heaters and clothes dry-
ers.
2. Do not overfill the fuel tank. Because fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill
out of the fuel tank.
3. Wipe up any spilled fuel immediately.
4. Be sure the fuel tank cap is closed se-
curely.
WARNING
EWB02532Gasoline is poisonous and can cause inju-
ry or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline or inhale a
lot of gasoline vapor, or get some gasoline
in your eyes, see your doctor immediately.
If gasoline spills on your skin, wash with
soap and water. If gasoline spills on your
clothing, change your clothes. Your Yamaha engine has been designed to
use regular unleaded gasoline with a research
octane number of 91 or higher (95 or higher
for Europe). If knocking or pinging occurs,
use a different brand of gasoline or premium
unleaded gasoline. Unleaded fuel will give
you longer spark plug life and reduced main-
tenance cost.

Portable fuel containers
If you carry a portable fuel container in the
bed of your Yamaha Wolverine, be sure to se-
cure it with the cap tightened before driving
the vehicle.
Always place a portable fuel container on the
ground before filling it. Before removing the
container cap, touch the container with the
fuel dispenser nozzle. Keep fuel dispenser
nozzle in contact with container inlet when fill-
ing. WARNING! Never refill a fuel container
in the bed of any vehicle. Fire may result
from a build-up of static electricity. The discharge of this build-up while refueling
can cause a spark and ignite the gasoline.

EBU31750Engine oilMake sure the engine oil is at the specified
level. Add oil as necessary. (See page 8-14.)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.
Recommended fuel:
Regular unleaded gasoline only
For Europe: Regular unleaded gasoline only
with a research octane number of 95 or
higher
Fuel tank capacity: 36.7 L (9.69 US gal, 8.07 Imp.gal)
Recommended engine oil type and quantity:See page 10-1.

EBU31760CoolantCheck the coolant level in the coolant reser-
voir when the engine is cold (the coolant level
will vary with engine temperature).
The coolant level is satisfactory if it is be-
tween the minimum and maximum level
marks on the coolant reservoir. If the coolant
level is at or below the minimum level mark,
add additional coolant to bring the level up to
maximum level mark. If coolant is not avail-
able, add distilled water. Change the coolant
every two years. (See page 8-24.)NOTICEECB02120Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
EBU36020Final gearMake sure there is no oil leaking from the final
gear case.EBU36030Differential gearMake sure there is no oil leaking from the dif-
ferential gear case.EBU31790Accelerator pedalCheck to see that the accelerator pedal oper-
ates correctly. It must operate smoothly and
spring back to the idle position fully when re-
leased. Have a Yamaha dealer repair as nec-
essary for proper operation.EBU31800Seat beltsMake sure that the seat belts are not frayed,
torn, stretched, or damaged. The seat belts
must move smoothly when pulled out and re-
tract on its own when released. The seat belts
must also lock up when quickly pulled out.
Coolant reservoir capacity (up to the maxi-
mum level mark): 0.28 L (0.30 US qt, 0.25 Imp.qt)

The latch plate should click securely into the
buckle and release when the release button is
pushed firmly. Wash off any dirt or mud that
could affect operation. Have a Yamaha dealer
repair as necessary for proper operation.
A crash can damage the restraint systems in
your vehicle. A damaged restraint system
may not properly protect the person using it,
resulting in serious injury or death in a crash.
To help make sure your restraint systems are
working properly after a crash, have them in-
spected and any necessary replacements
made as soon as possible.EBU31810Passenger handholdCheck that the handhold bar and its supports
are in good condition. Confirm that the lock-
ing pins are securely fastened, and then push
and pull on the handhold to make sure that it
is not loose.
EBU31820SteeringPark on level ground. Turn the steering wheel
right and left. Check for excessive free play,
abnormal noises, or a rough feeling. Have a
Yamaha dealer repair as necessary for proper operation.EBU31831Fittings and fastenersAlways check the tightness of chassis fittings
and fasteners before a drive. Take the vehicle
to a Yamaha dealer or refer to the Service
Manual for correct tightening torque.EBU31840Instruments, lights and switchesCheck that all instrument s, lights and switch-
es are working properly. Correct if necessary.

sure all control cables work smoothly before
starting off. WARNING! Control cables can
freeze in cold weather and you could be
unable to control the vehicle.

EBU33481
TiresCheck tire pressure regularly to make sure it
is at the recommended specifications. Also
check for wear and damage.
Tire pressure
Use the tire pressure gauge to check and ad-
just tire pressures when the tires are cold. Tire
pressures must be equal on both sides.
WARNING! Operation of this vehicle with improper tire pressure may cause severe
injury or death from loss of control or roll-
over. Tire pressure below the minimum specified could also cause the tire to dis-
lodge from the rim under severe driving
conditions.
[EWB04120]
Set tire pressures to the following specifica-
tions:Recommended tire pressure:
Vehicle load:0 - maximumFront: 75.0 kPa (0.750 kgf/cm², 11 psi)
Rear: 75.0 kPa (0.750 kgf/cm², 11 psi)
Minimum tire pressure: Vehicle load:0 - maximumFront: 70.0 kPa (0.700 kgf/cm², 10 psi)
Rear: 70.0 kPa (0.700 kgf/cm², 10 psi)
Maximum vehicle load*: 327.0 kg (721 lb)
* Total weight of operator, passenger, acces- sories, cargo, and (if applicable) trailer
tongue weight
