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.

TIPA special wrench can be obtained at a
Yamaha dealer to make this adjustment.
 The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The shorter distance A is, the higher
the spring preload; the longer distance A is,
the lower the spring preload. With each
complete turn of the adjusting nut, distance
A is changed by 1.5 mm (0.06 in).
3. Tighten the locknut to the specified
torque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten it to the specified torque.

Rebound damping force
Turn the rebound damping force adjusting
screw in direction (a) to increase the rebound
damping force and thereby harden the damp-
ing, and in direction (b) to decrease the re-
bound damping force and thereby soften the
damping.Compression damping force
Fast compression damping force
To increase the fast compression damping
force and thereby harden the compression
damping, turn the fast compression damping
force adjusting bolt in direction (a). To de-
crease the fast compression damping force
and thereby soften the compression damp-
ing, turn the adjusting bolt in direction (b).

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.
The latch plate should click securely into the
buckle and release when the release button is
pushed firmly. Wash off any dirt or mud that
could affect operation. Have a Yamaha dealer
repair as necessary for proper operation.
A crash can damage the restraint systems in
your vehicle. A damaged restraint system
may not properly protect the person using it,
resulting in serious injury or death in a crash.
To help make sure your restraint systems are
working properly after a crash, have them in-
spected and any necessary replacements
made as soon as possible.
EBU31810Passenger handholdCheck that the handhold bar and its supports
are in good condition. Confirm that the lock-
ing pins are securely fastened, and then push
and pull on the handhold to make sure that it
is not loose.EBU31820SteeringPark on level ground. Turn the steering wheel
right and left. Check for excessive free play,
abnormal noises, or a rough feeling. Have a
Yamaha dealer repair as necessary for proper operation.EBU31832Fittings and fastenersAlways check the tightness of chassis fittings
and fasteners before starting off. Take the ve-
hicle to a Yamaha dealer or refer to the Servi-
ce Manual for correct tightening torque.

EBU31922On-Command drive knobThe vehicle handles differently in each of the drive modes (“2WD”, “4WD” and “DIFF LOCK”). For
example, the vehicle requires more effort to turn in “DIFF LOCK” than in “2WD”. Always stop the
vehicle before changing the position of the On -Command drive knob. The meter display changes
according to the selected drive mode. The different drive indicators, and the differential gear lock
indicator light “DIFF. LOCK” come on as follows:
Knob position Indication Drive mode
No indicator light.
“2WD” (two-wheel drive): Power is supplied to the rear
wheels.
“4WD” (four-wheel drive): Power is supplied to the rear and
front wheels.
“DIFF LOCK” (four-wheel drive with the differential gear
locked): Power is supplied to the rear and front wheels and
the differential gear is locked.
Unlike in four-wheel drive, all wheels turn at the same
speed.

TIPWhen the knob is set to “DIFF LOCK” or “4WD”, the differential gear lock indicator and indica-
tor light will flash until the differential gear is completely locked or unlocked.
 When the indicator and indicator light are flas hing, turning the steering wheel back and forth
will help the differential gear lock to engage or disengage.
 Driving with the differential gear not properly engaged or disengaged (e.g., when the indicator
and indicator light are flashing) will cause the vehicle speed to be limited until the differential
gear is completely engaged or disengaged. UB3D7AE0.book Page 6 Tuesday, November 7, 2017 9:38 AM

Adjusting the handhold positionThe handhold can be adjusted to one of three
positions to suit the passenger’s preference.Adjust the handhold position as follows.
1. Remove the locking pins.
2. Slide the handhold to the desired position
and align the holes in the handhold bar
with the holes in the handhold supports.

Become familiar with the way the vehicle feels
in low and high ranges, first in two-wheel
drive “2WD” and then in four-wheel drive
“4WD” and four-wheel drive with the differen-
tial locked “DIFF LOCK”. Steering may take
more effort in four-wheel drive with the differ-
ential locked “DIFF LOCK”. Also practice
driving in reverse.
Take the time to learn basic operation of the
vehicle before attempting more difficult ma-
neuvers.Getting ready to ride
Perform the Pre-Operation Checks on page
5-1. Follow the instructions starting on page
6-2 to start the engine.
Turning
Use care in turns – tu
rning the steering wheel
too far or too fast can result in loss of control
or a rollover. Slow down before entering
turns. When making tight turns from a stand-
still or at slow speeds, avoid sudden or hard
acceleration. Driving aggressively or making
abrupt maneuvers even on flat, open areas
can cause side rollovers. Avoid sideways slid-
ing, skidding, or fishtailing (rear-wheel slid-
ing), and never do donuts. If you feel the
Wolverine begin to slide sideways or the rear
wheels begin to slide during a turn, steer into
the direction of the slide, if possible, and
gradually let off the accelerator pedal to re-
gain directional control and avoid rollover. For
example, if you feel the back of the vehicle
start to slide to your right, steer to the right.UB3D7AE0.book Page 14 Tuesday, November 7, 2017 9:38 AM
