WARNING
EWB01600Never attempt to turn the ATV around on any
hill until you have mastered the turning tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning on
any hill. Avoid crossing the side of a steep hill
if possible.
When crossing the side of a hill:
Always follow proper procedures as de-
scribed in the Owner’s Manual.
Avoid hills with excessively slippery or loose
surfaces.
Shift your weight to the uphill side of theATV.If your ATV has stalled or stopped and you believe
you can continue up the hill, restart carefully to
make sure you do not lift the front wheels which
could cause you to lose control. If you are unable
to continue up the hill, dismount the ATV on the up-
hill side. Physically turn the ATV around and then
descend the hill.
If you start to roll backwards, DO NOT apply either
brake abruptly. If you are in 2WD, apply only the
front brake. If you are in 4WD (for four-wheel-drive
models), because all wheels are interconnected by
the drive train, applying either brake will brake all
wheels, therefore, avoid sudden application of ei-
ther the front or rear brake as the wheels on the up-

7-17
7 hill side could come off the ground. The ATV could
easily tip over backwards. Apply both the front and
rear brakes gradually, or dismount the ATV imme-
diately on the uphill side.
WARNING
EWB01791Maintain a steady speed when climbing a hill.
If you lose all forward speed:
Keep weight uphill.
Apply the brakes.
Apply the parking brake after you are
stopped.
If you begin rolling backwards:
Keep weight uphill.
2WD: Never apply the rear brake while rolling
backwards. Apply the front brake. When fully
stopped, apply the rear brake as well, and
then lock the parking brake.
4WD: Apply both front and rear brakes grad-
ually. When fully stopped, lock the parking
brake.
Dismount on uphill side or to a side if pointed
straight uphill. Turn the ATV around and re-
mount, following the procedure described inthe Owner’s Manual.RIDING DOWNHILL
When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as pos-
sible. Move back on the seat and sit with your arms
straight. Engine compression will do most of the
braking for you. For maximum engine compres-
sion braking effect, change to 4WD (for four-
wheel-drive models), before beginning to descend
the hill. Improper braking may cause a loss of trac-
tion.
Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction may
be adversely affected by these surfaces. Improper
braking may also cause a loss of traction.

7When this ATV is in 4WD (for four-wheel-drive
models), all wheels (front and rear) are intercon-
nected by the drive train. This means that applying
either the front brake or the rear brake will brake all
wheels. When descending hills, using either brake
lever or the brake pedal will brake the wheels on
the downhill side. Avoid sudden application of ei-
ther the front or rear brake because the wheels on
the uphill side could come off the ground. Apply
both the front and rear brakes gradually.
Whenever possible, ride your ATV straight down-
hill. Avoid sharp angles which could allow the ATV
to tip or roll over. Carefully choose your path and
ride no faster than you will be able to react to ob-
stacles which may appear.
WARNING
EWB01620Always follow proper procedures for going
down hills as described in this Owner’s Manu-
al.
Note: a special technique is required when
braking as you go down a hill.
Always check the terrain carefully before
you start down any hill.
Shift your weight backward.
Never go down a hill at high speed.

Avoid going down a hill at an angle that
would cause the ATV to lean sharply to one
side. Go straight down the hill where possi-ble.
CROSSING A SLOPE
Traversing a sloping surface on your ATV requires
you to properly position your weight to maintain
proper balance. Be sure that you have learned the
basic riding skills on flat ground before attempting

8-18
88. Check the final gear case for oil leakage. If oil
is leaking, check for the cause.
9. Install the final gear case guard by installing
the bolts and tightening them to the specified
torque.
EBU23433Changing the differential gear oil (4WD
model)The differential gear case must be checked for oil
leakage before each ride. If any leakage is found,
have a Yamaha dealer check and repair the ATV.
In addition, the differential gear oil must be
changed as follows at the intervals specified in the
periodic maintenance and lubrication chart.
1. Place the ATV on a level surface.
2. Place an oil pan under the differential gear
case to collect the used oil.3. Remove the differential gear oil filler bolt and
the differential gear oil drain bolt to drain the
oil from the differential gear case. Tightening torque:
Final gear oil filler bolt:
23 Nm (2.3 m·kgf, 17 ft·lbf)
Tightening torque:
Final gear case guard bolt:
16 Nm (1.6 m·kgf, 11 ft·lbf)
