The tailgate can also be installed at the front
of the cargo bed. Install the tailgate and hook
the latches as shown.EBU33611Adjusting the front shock absorber as-
sembliesThese shock absorber assemblies are
equipped with a spring preload adjusting nut,
a rebound damping force adjusting screw, a
compression damping force adjusting bolt(for fast compression damping), and a com-
pression damping force adjusting screw (for
slow compression damping).
WARNING
EWB02492
Suspension components become hot
during operation. Never touch the com-
pression damping force adjusting bolt
and screw, the rebound damping force
adjusting screw or the oil reservoir with
your bare hand or skin until suspension
components have cooled.
 Always adjust the shock absorber as-
semblies on the left and right side to the
same setting. Uneven adjustment can
cause poor handling and loss of stability,
which could lead to an accident. NOTICEECB00091Never turn an adjusting mechanism be-
yond the minimum and maximum settings.

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
EWB00411These 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-
semblies 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. EBU33620Adjusting the rear shock absorber as-

a damping force adjusting mechanism may
not exactly match the following specifications
due to small differences in production, the ac-
tual number of clicks or turns always repre-
sents the entire adjusting range. To obtain a
precise adjustment, it would be advisable to

FOR YOUR SAFETY – PRE-OPERATION CHECKS
EBU31580Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition.
Always follow the inspection and maintenance procedures and schedules described in the Own-
er’s Manual.
WARNING
EWB00482Failure to inspect or maintain the vehicle properly increases the possibility of an accident
or equipment damage. Do not operate the vehicle if you find any problem. If a problem can-
not be corrected by the procedures provided in this manual, have the vehicle inspected by
a Yamaha dealer. Before using this vehicle, check the following points:
ITEM ROUTINE PAGE
Brakes • Check operation, free play, fluid level, and fluid leakage.
• Fill with DOT 4 brake fluid if necessary. 5-3, 8-38, 8-41
Parking brake • Check for proper operation. 8-41
Fuel • Check fuel level.
• Fill with the recommended fuel if necessary. 5-3
Engine oil • Check oil level.
• Fill with oil to proper level if necessary. 5-5, 8-14

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: 37.0 L (9.77 US gal, 8.14 Imp.gal)
Recommended engine oil type and quantity:See page 10-1.

EBU31830Fittings and fastenersAlways check the tightness of chassis fittings
and fasteners before a ride. Take the vehicle
to a Yamaha dealer or refer to the Service
Manual for correct tightening torque.EBU31840Instruments, lights and switchesCheck that all instruments, lights and switch-
es are working properly. Correct if necessary.EBU31850Control cablesWhen riding in cold weather, always make
sure all control cables work smoothly before
you begin riding. WARNING! Control cables
can freeze in cold weather and you could
be unable to control the vehicle.

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 riding
conditions.
[EWB02542]
Set tire pressures to the following specifica-
tions:
