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.
