Compression damping force (for slow com-pression damping)To increase the compression damping force
and thereby harden the compression damp-
ing, turn the compression damping force ad-
justing screw in direction (a). To decrease the
compression damping force and thereby
soften the compression damping, turn the
adjusting screw in direction (b).

WARNING
EWB03500These shock absorber assemblies contain
highly pressurized nitrogen gas. Read and
understand the following information be-
fore handling the shock absorber assem-
blies.
 Do not tamper with or attempt to open
the cylinder assemblies.
 Do not subject the shock absorber as-
sembly to an open flame or other high
heat source. This may cause the unit to
explode due to excessive gas pressure. 
Do not deform or damage the cylinders
in any way. Cylinder damage will result in
poor damping performance.
 Do not dispose of a damaged or worn
out shock absorber assembly yourself.
Take the shock absorber assembly to a
Yamaha dealer for any service.

bracket and a 5 cm (2 in) receiver for a stan-
dard trailer hitch. Tr ailer towing equipment
can be obtained at a Yamaha dealer. (See
page 6-7 for precaution information.)

EBU32950Auxiliary DC jackThe auxiliary DC jack is located at the right
side of the storage compartment under the
multi-function meter. The auxiliary DC jack
can be used for suitable work lights, radios,
etc. The auxiliary DC jac k s h o u l d o n l y b e u s e d
when the engine is running and the headlights
are turned off.
NOTICEECB02250 Do not use accessories requiring more
than the stated maximum capacity. Do-
ing so may overload the circuit and cau-
se the fuse to blow.
 If accessories are used without the en-
gine running, the ba ttery may discharge.
 Do not use an automotive cigarette light-
er or other accessories with a plug that
gets hot, because the jack can be dam-
aged. 1. Set the light switch to “ ”.
2. Turn the accessory off.
3. Start the engine. (See page 6-2.)
4. Open the auxiliary DC jack cap, and then

EBU31730Front 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
8-43.)
 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 8-42.) 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 ride. 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 8-41.)
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.
[EWB03270]
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: 37 L (9.77 US gal, 8.14 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 8-25.)NOTICEECB02120Hard water or salt water is harmful to the
engine. You may use soft water if you can-
not get distilled water.
EBU31771Final gear oilMake sure the final gear oil is at the specified
level. Add oil as necessary. (See page 8-20
for details.)
If desired, an SAE 80W-90 hypoid gear oil
may be used instead.TIPGL-4 is a quality and additive rating; GL-5 or
GL-6 rated hypoid gear oils may also be used. EBU31780Differential gear oilMake sure the differential gear oil is at the
specified level. Add oil as necessary. (See
page 8-22 for details.)
Coolant reservoir capacity (up to the maxi-
mum level mark):0.28 L (0.30 US qt, 0.25 Imp.qt)
Recommended oil:SAE 80 API GL-4 Hypoid gear oil
Recommended oil: SAE 80 API GL-4 Hypoid gear oil
