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

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.

into the oil filler hole and then remove it
again to check the oil level.
TIPThe engine oil should be between the mini-
mum and maximum level marks. 7. If the engine oil is at or below the mini-mum level mark, add sufficient oil of the
recommended type to raise it to the cor-
rect level.

oil at the intervals specified in the general
maintenance and lubrication chart.
Checking the final gear oil level 1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its gasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole. 3. If the oil is below the brim of the filler hole,
add sufficient oil of the recommended
type to raise it to the correct level.
NOTICE: Be sure no foreign material
enters the final gear case.
