FOR YOUR SAFETY – PRE-OPERATION CHECKS
EBU31582Inspect 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, 8-41, 8-44
Parking brake • Check for proper operation. 8-44
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 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

OPERATION
EBU31880Read the Owner’s Manual carefully to be-
come familiar with all controls. If there is a
control or function you do not understand,
ask your Yamaha dealer.
WARNING
EWB03290Failure to familiarize yourself with the con-
trols can lead to loss of control, which
could cause an accident or injury. EBU31890Engine break-inThere is never a more important period in the
life of your vehicle than the period between 0
and 20 hours.
For this reason, we ask that you read the fol-
lowing material carefully. Because the engine
is brand new, you must not put an excessive
load on it for the first several hours of opera-
tion. During the first 20 hours, the variousparts in the engine wear and polish them-
selves to achieve the correct operating clear-
ances.
During this period, prolonged full-throttle op-
eration or any condition that might result in
excessive engine heating must be avoided.
However, momentary (2–3 seconds maxi-
mum) full-throttle operation under load does
not harm the engine.
Each full-throttle acceleration sequence
should be followed with a substantial rest pe-
riod for the engine, by cruising at lower r/min
so the engine can rid itself of the temporary
build-up of heat. If any abnormality is noticed
during this period, consult a Yamaha dealer.
0–10 hours:
Avoid continuous operation above 1/2-throt-
tle. Allow a cooling-off period of 5 to 10 minu-
tes after every hour of operation. Vary the
speed of the vehicle from time to time. Do not
operate it at one set throttle position.UBN57AE0.book Page 1 Tuesday, November 24, 2015 1:42 PM
