lowing checklist and related information as a guide. Also, follow the service intervals in the peri-
odic maintenance chart to keep the vehicle in safe operating condition.
WARNING

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. Pre-operation checklist

For EuropeTIPWhen refueling, check that the gasoline pump
nozzle has same fuel identification mark.
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]

NOTICEECB00301In order to prevent cl utch 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. EBU31761CoolantCheck the coolant level in the reservoir and
replenish if necessary. (See page 8-25.)

gear case.EBU36030Differential gearMake sure there is no oil leaking from the dif-
ferential gear case.EBU31791Accelerator pedalBefore starting the engine, confirm that the
accelerator pedal operates correctly. It
should depress smoothly and spring back to
the idle position when released. Also check
the accelerator pedal for excessive free play.
