WARNING


Never operate the vehicle on hills too steep
for it or your abilities. The vehicle can over-
turn more easily on extremely steep hills
than on level surfaces or small hills. Prac-
tice on smaller hills before attempting
large hills.


Do not drive across the face of a hill. Go
straight up the hill.


Never operate vehicles on hills steeper
than 15°.
Before climbing the hill, first be sure you are oper-
ating in low range 4WD or, if necessary, with 4WD
Diff. Lock. To climb a hill, you need traction, mo-
mentum, and steady throttle. Travel fast enough to
keep your momentum going, but not so fast that
you cannot react to changes in the terrain as you
climb. Slow down when you reach the crest of the
hill if you cannot clearly see what is on the other
side – there could be another person, an obstacle,
or a sharp drop off.

WARNING
Going down a hill improperly could cause loss
of control or cause the vehicle to overturn.

Always check the terrain carefully before
you start down any hill.


Never go down a hill at high speed.


Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side. Go straight down the hill where
possible.
Before starting down hill, make sure the vehicle is
in low-range 4WD. On most slopes, this will let you
use engine braking to help you go downhill slowly.
Go as slowly as possible. If you are starting to go
too fast, apply the brakes gently. Avoid sudden ap-
plication of the brakes, which could cause the ve-
hicle to start sliding.
If you are sliding or skidding, try to steer in the di-
rection the vehicle is sliding to help you regain con-
trol.

CROSSING THROUGH SHALLOW WATER
If you must cross shallow, slow moving water up to
the depth of the vehicle’s floorboards, choose your
path carefully to avoid sharp drop-offs, large rocks,
or slippery surfaces that could cause the vehicle to
overturn. Never operate through water deeper
than 33 cm (13 in) or fast flowing water.
Wet brakes may have reduced effectiveness. After
leaving the water, test your brakes. If necessary,
apply the brakes several times to let friction dry out
the linings.
WARNING
Never operate this vehicle in fast-flowing water
or in water deeper than 33 cm (13 in). This
could result in a loss of control and an acci-
dent, including a overturn, which could in-
crease the risk of drowning. Remember that
wet brakes may have reduced stopping ability.
Test your brakes after leaving water. If neces-
sary, apply them several times to let friction
dry out the linings.

RIDING OVER ROUGH TERRAIN
Operating over rough terrain should be done with
caution. Look for obstacles that could cause dam-
age to the vehicle or could lead to a rollover or ac-
cident. Avoid jumping the vehicle as injury, loss of
control, and damage to the vehicle could occur.
WARNING
Go slowly and be extra careful when operating
this vehicle on unfamiliar terrain. Always be
alert to changing terrain conditions when oper-
ating the vehicle.

ENCOUNTERING OBSTACLES ON THE TRAIL
If you cannot go around an obstacle such as a fall-
en tree trunk or a ditch, stop the vehicle where it is
safe to do so. Set the parking brake and get out to
inspect the area thoroughly. Look from both your
approach side and the exit side. If you believe you
can continue safely, decide the path that will allow
you to get over the obstacle at as close to a right
angle as possible to minimize vehicle tipping. Go
only fast enough to maintain your momentum but
still give yourself plenty of time to react to changes
in conditions. If there is any question about your
ability to maneuver safely over the obstacle, you
should turn around, if the ground is flat and you
have the room, or back up until you find a less dif-
ficult path.
WARNING
Before operating in a new area, check for ob-
stacles. Use extreme caution when operating
over large obstacles, such as large rocks or
fallen trees.

Checking the brake pedal
Have a Yamaha dealer check the brakes at the in-
tervals specified in the periodic maintenance and
lubrication chart. There should be no free play in
the brake pedal. The brakes should operate
smoothly and there should be no brake drag. If the
brakes feel soft or spongy, this could indicate air in
the brake system. Have a Yamaha dealer check
the brake system if necessary.
WARNING
Operating with improperly serviced or adjust-
ed brakes could cause loss of braking ability,
which could lead to an accident.
After servicing:

Make sure the brakes operate smoothly
and that the brake pedal position is cor-
rect.


Make sure the brakes do not drag.


All air must be bled from the brake system.
Replacement of brake components requires
professional knowledge. These procedures
should be performed by a Yamaha dealer.
