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. TIPAlthough the total number of clicks or turns of
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
check the number of clicks or turns of each
damping force adjusting mechanism and to
modify the specifications as necessary.
Spring preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in direction (a) to increase the spring pre-
load and thereby harden the suspension,
and in direction (b) to decrease the spring
preload and thereby soften the suspen-
sion.

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]
EBU31750Engine oilMake sure the engine oil is at the specified
level. Add oil as necessary. (See page 8-14.)
Recommended fuel: Regular unleaded gasoline only
For Europe: Regular unleaded gasoline only
with a research octane number of 95 or

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.)
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.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.
If the accelerator pedal is not in correct work-
ing order, have the vehicle inspected before
starting off.
Recommended engine oil type and quantity:
See page 10-1.
