INTRODUCTION

Congratulations on your purchase of the Yamaha YFM80R. It represents the result of many years of
Yamaha experience in the production of fine sporting, touring, and pacesetting racing machines. With
the purchase of this Yamaha, you can now appreciate the high degree of craftsmanship and reliability
that have made Yamaha a leader in these fields.
This manual will provide you with a good basic understanding of the features and operation of this
machine.

This manual includes important safety information. It provides information about special tech­niques and skills necessary to ride your machine.

It also includes basic maintenance and inspection procedures. If you have any questions regarding the
operation or maintenance of your machine, please consult a Yamaha dealer.

AN IMPORTANT SAFETY MESSAGE:

8 READ THIS MANUAL TOGETHER WITH TIPS FOR THE ATV RIDER CAREFULLY AND COM-

PLETELY BEFORE OPERATING YOUR MACHINE. MAKE SURE YOU UNDERSTAND ALL
INSTRUCTIONS.

8 PAY CLOSE ATTENTION TO THE WARNING AND CAUTION LABELS ON THE MACHINE.
8 NEVER OPERATE AN ATV WITHOUT PROPER TRAINING OR INSTRUCTION. FREE TRAINING

IS AVAILABLE TO ANYONE WHO BUYS A NEW ATV. CALL 1-800-887-2887 FOR MORE INFOR­MATION.

8 THIS ATV, AND ANY OTHER ATV OVER 70cc, SHOULD NOT BE OPERATED BY A CHILD

UNDER 12 YEARS OF AGE.

AN IMPORTANT NOTE TO PARENTS:

This ATV is not a toy. Before you let your child ride this ATV, you should understand the instructions
and warnings in this Owner’s Manual. Then be sure your child understands and will follow them.
Children differ in skills, physical abilities and judgment. Some children may not be able to operate an
ATV safely. Parents should supervise their child’s use of the ATV at all times. Parents should permit
continued use only if they determine that the child has the ability to operate the ATV safely.

Your ATV was delivered with an adjustable speed limiter and also with an air intake restrictor plate.
Yamaha recommends that all beginners start off with the speed limiter screw turned in and the air
intake restrictor plate installed to limit the amount of speed available while they learn. The limiter screw
may be gradually turned out to increase maximum speed as the beginner becomes more familiar with
operating the ATV. Parents should decide when to adjust the ATV for more power as their youngster’s
riding skills improve. Once the ATV rider can operate with skill at the top speed permitted by adjusting
the speed limiter alone, the air intake restrictor plate can be removed. Since removal of this plate will
result in a significant increase in power, turn the speed limiter back in again; adjust it out in stages as
you did before.

If your child is a beginner or is inexperienced, he or she should take a training course. See the previ­ous page for information about the free training available to purchasers of new ATVs.

q SAFETY INFORMATION

AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE. An ATV handles differently from
other vehicles including motorcycles and cars. A collision or rollover can occur quickly, even during
routine maneuvers such as turning and riding on hills or over obstacles, if you fail to take proper pre­cautions.

SEVERE INJURY OR DEATH can result if you do not follow these instructions:

8 Read this manual and all labels carefully and follow the operating procedures described.
8 Never operate an ATV without proper training or instruction. Take a Training Course. Beginners

should receive training from a certified instructor. Contact an authorized ATV dealer or call
1-800-887-2887 to find out about the training courses nearest you.

8 Always follow the age recommendation:

- A child under 12 years old should never operate an ATV with engine size greater than 70cc.

- A child under 16 years old should never operate an ATV with engine size greater than 90cc.

8 Never allow a child under age 16 to operate an ATV without adult supervision, and never allow con-

tinued use of an ATV by a child if he or she does not have the abilities to operate it safely.

8 Never carry a passenger on an ATV.

2-1

8 Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, parking lots

and streets.

8 Never operate an ATV on any public street, road or highway, even a dirt or gravel one.
8 Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You

should also wear eye protection (goggles or face shield), gloves, boots, long-sleeved shirt or jacket,
and long pants.

8 Never consume alcohol or drugs before or while operating this ATV.
8 Never operate at speeds too fast for your skills or the conditions. Always go at a speed that is prop-

er for the terrain, visibility and operating conditions, and your experience.

8 Never attempt wheelies, jumps, or other stunts.
8 Always inspect your ATV each time you use it to make sure it is in safe operating condition. Always

follow the inspection and maintenance procedures and schedules described in this manual.

8 Always keep both hands on the handlebars and both feet on the footrests of the ATV during opera-

tion.

8 Always go slowly and be extra careful when operating on unfamiliar terrain. Always be alert to

changing terrain conditions when operating the ATV.

2-2

8 Never operate on excessively rough, slippery or loose terrain until you have learned and practiced

the skills necessary to control the ATV on such terrain. Always be especially cautious on these
kinds of terrain.

8 Always follow proper procedures for turning as described in this manual. Practice turning at low

speeds before attempting to turn at faster speeds. Do not turn at excessive speed.

8 Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller hills

before attempting larger hills.

8 Always follow proper procedures for climbing hills as described in this manual. Check the terrain

carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces.
Shift your weight forward. Never open the throttle suddenly or make sudden gear changes. Never
go over the top of a hill at high speed.

8 Always follow proper procedures for going down hills and for braking on hills as described in this

manual. 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 vehicle
to lean sharply to one side. Go straight down the hill where possible.

8 Always follow proper procedures for crossing the side of a hill as described in this manual. Avoid

hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV.
Never attempt to turn the ATV around on any hill until you have mastered the turning technique
described in this manual on level ground. Avoid crossing the side of a steep hill if possible.

2-3

8 Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stalling,

use proper gear and maintain a steady speed when climbing a hill. If you stall or roll backwards, fol­low the special procedure for braking described in this manual. Dismount on the uphill side or to a
side if pointed straight uphill. Turn the ATV around and remount, following the procedure described
in this manual.

8 Always check for obstacles before operating in a new area.

Never attempt to operate over large obstacles, such as large rocks or fallen trees. Always follow
proper procedures when operating over obstacles as described in this manual.

8 Always be careful when skidding or sliding. Learn to safely control skidding or sliding by practicing

at low speeds and on level, smooth terrain. On extremely slippery surfaces, such as ice, go slowly
and be very cautious in order to reduce the chance of skidding or sliding out of control.

8 Never operate an ATV in fast flowing water or in water deeper than that recommended in this manu-

al. Remember that wet brakes may have reduced stopping ability. Test your brakes after leaving
water. If necessary, apply them several times to let friction dry out the linings.

8 Always use the size and type tires specified in this manual. Always maintain proper tire pressure as

described in this manual.

8 Never modify an ATV through improper installation or use of accessories.

2-4

8 Never exceed the stated load capacity for an ATV. Cargo should be properly distributed and

securely attached. Reduce speed and follow instructions in this manual for carrying cargo or pulling
a trailer. Allow greater distance for braking.

Throttle lever

Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying
the throttle position. Because the throttle is
spring-loaded, the machine will decelerate, and
the engine will return to an idle any time the
hand is removed from the throttle lever.

1. Throttle lever

Before starting the engine, check the throttle to
be sure it is operating smoothly. Make sure it
returns to the idle position as soon as the lever
is released.

q

WARNING

POTENTIAL HAZARD

Malfunction of throttle.

WHAT CAN HAPPEN

The throttle could be hard to operate, mak­ing it difficult to speed up or slow down
when you need to. This could cause an
accident.

HOW TO AVOID THE HAZARD

Check the operation of the throttle lever
before you start the engine. If it does not
work smoothly, check for the cause.
Correct the problem before riding the ATV.
Consult a Yamaha dealer if you can’t find
or solve the problem yourself.

a

Speed limiter

The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed
to the maximum. Screwing in the adjuster limits
the maximum engine power available and
decreases the maximum speed of the ATV.
Your ATV was delivered with an adjustable
speed limiter and also with an air intake restric­tor plate. Yamaha recommends that all begin­ners start off with the speed limiter screw turned
in and the air intake restrictor plate installed to
limit the amount of speed available while they
learn. The limiter screw may be gradually turned
out to increase maximum speed as the beginner
becomes more familiar with operating the ATV.
Parents should decide when to adjust the ATV
for more power as their youngster’s riding skills
improve. Once the ATV rider can operate with
skill at the top speed permitted by adjusting the
speed limiter alone, the air intake restrictor plate
can be removed. Since removal of this plate will

result in a significant increase in power, turn the
speed limiter completely back in again; adjust it
out in stages as you did before.
Adjusting for maximum throttle lever movement
without removing the air intake restrictor plate
will cause the engine to run roughly at higher
speeds.
For air intake restrictor plate removal instruc­tions, see page 8-13.

Fuel

Make sure there is sufficient gasoline in the
tank.

Recommended fuel:

UNLEADED GASOLINE ONLY

Fuel tank capacity:

Total:

6.8 L (1.5 Imp gal, 1.8 US gal)

Reserve:

0.9 L (0.2 Imp gal, 0.2 US gal)

cC

Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system.

Your Yamaha engine has been designed to use reg­ular unleaded gasoline with a pump octane number
([R+M]/2) of 86 or higher, or research octane number
of 91 or higher. If knocking or pinging occurs, use a
different brand of gasoline or premium unleaded fuel.

5-3

Unleaded fuel will give you longer spark plug life
and reduced maintenance cost.

Gasohol

There are two types of gasohol; gasohol con­taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10%. Gasohol
containing methanol is not recommended by
Yamaha because it may cause fuel system
damage or vehicle performance problems.

q

WARNING

POTENTIAL HAZARD

Improper care when refueling.

WHAT CAN HAPPEN

Fuel can spill, which can cause a fire and
severe injury.
Fuel expands when it heats up. If the fuel
tank is overfilled, fuel could spill out due
to heat from the engine or the sun.

HOW TO AVOID THE HAZARD

Do not overfill the fuel tank. Be careful not
to spill fuel, especially on the engine or
exhaust pipe. Wipe up any spilled fuel
immediately. Be sure the fuel tank cap is
closed securely.
Do not refuel right after the engine has
been running and is still very hot.

EBU02092

Engine break-in

There is never a more important period in the
life of your machine than the period between
zero and 20 hours.
For this reason, we ask that you carefully read
the following material. Because the engine is
brand new, you must not put an excessive load
on it for the first several hours of running. During
the first 20 hours, the various parts in the engine
wear and polish themselves to the correct oper­ating clearances.
During this period, prolonged full throttle opera­tion or any condition which might result in exces­sive engine heating must be avoided. However,
momentary (2-3 seconds maximum) full throttle
operation under load does not harm the engine.
Each full throttle acceleration sequence should
be followed with a substantial rest period for the
engine by cruising at lower r/min so the engine
can rid itself of the temporary build up of heat.

If any abnormality is noticed during this period,
consult a Yamaha dealer.

0-10 hours:

Avoid continuous operation above half throttle.
Allow a cooling off period of five to ten minutes
after every hour of operation. Vary the speed of
the machine from time to time. Do not operate it
at one set throttle position.

10-20 hours:

Avoid prolonged operation above 3/4 throttle.
Rev the machine freely through the gears but do
not use full throttle at any time.

After break-in:

Avoid prolonged full throttle operation. Vary
speeds occasionally.

EBU00222

Accessories

Accessories can affect the handling and control
of your ATV. Keep the following in mind when
considering an accessory or operating an ATV
which has accessories.
8 Choose only accessories designed for your

ATV. Your Yamaha dealer has a variety of
genuine Yamaha accessories. Other acces­sories may also be available on the market.
However, it is not possible for Yamaha to test
all non-Yamaha accessories, nor have any
control over the quality or suitability of them.
Choose a genuine Yamaha accessory, or one
that is equivalent in design and quality.

8 Accessories should be rigidly and securely

mounted. An accessory which can shift posi­tion or come off while you are riding could
affect your ability to control the ATV.

8 Do not mount an accessory where it could

interfere with your ability to control the ATV.
Examples include (but are not limited to) a
heavy or bulky object attached to the handle­bars which could make steering difficult, an
accessory that limits your ability to move
around on the seat, or one that limits your
view.

8 Use extra caution when riding an ATV with

accessories. The ATV may handle differently
than it does without accessories.

EBU00584

Loading

As originally equipped, this ATV is not designed
to carry cargo or tow a trailer. If you choose to
add accessories so that you can carry cargo or
tow a trailer, you must use common sense and
good judgment. Keep the following points in
mind:
8 Never exceed the weight limits shown. An

overloaded ATV can be unstable.

MAXIMUM LOADING LIMIT

Vehicle loading limit (total weight of
cargo, rider and accessories):

95 kg (209 lb)

8 Load cargo on the carriers as close to the

center of the vehicle as possible. Put cargo at
the rear of the front carrier and at the front of
the rear carrier. Center the load from side to
side.

8 Tie down cargo securely to the carriers. Make

sure cargo in the trailer cannot move around.
A shifting load can cause an accident.

8 Make sure the load does not interfere with

controls or your ability to see where you are
going.

8 Ride more slowly than you would without a

load. The more weight you carry, the slower
you should go. Although conditions vary, it is
good practice not to exceed 2nd gear when­ever you are carrying heavier loads or when
towing a trailer.

8 Allow more braking distance. A heavier vehi-

cle takes longer to stop.

8 Avoid making sharp turns unless at very slow

speeds.

8 Avoid hills and rough terrain. Choose terrain

carefully. Added weight affects the stability
and handling of the ATV.

Speed limiter

For riders inexperienced with this model, this
model is equipped with a speed limiter in the throt­tle lever housing. The speed limiter limits the
power and top speed of the ATV. Turning the
screw in decreases top speed, and turning it out
increases top speed. This model also has an
intake restrictor plate to limit the amount of engine
power available.
Yamaha recommends that all beginning riders
start off with the speed limiter turned in and the air
intake restrictor plate installed to limit the amount
of speed available while they learn. The limiter may
be gradually adjusted to increase maximum speed
as the beginner becomes more familiar with oper­ating the ATV. Parents should decide when to
adjust the ATV for more power as their youngster’s
riding skills improve. Once the ATV rider can oper­ate with skill at the top speed permitted by adjust­ing the speed limiter alone, the air intake restrictor
plate can be removed. Since removal of this plate
will result in a significant increase in power, turn
the speed limiter back in again; adjust it out in
stages as you did before.

on excessively rough, slippery or loose
terrain.

WHAT CAN HAPPEN

Could cause loss of traction or vehicle
control, which could result in an accident,
including an overturn.

HOW TO AVOID THE HAZARD

Do not operate on excessively rough, slip­pery or loose terrain until you have
learned and practiced the skills necessary
to control the ATV on such terrain. Always
be especially cautious on these kinds of
terrain.

7-19

When riding in an area where you might not
easily be seen, such as desert terrain, mount a
caution flag on the ATV. DO NOT use the flag
pole bracket as a trailer hitch.

q

WARNING

POTENTIAL HAZARD

Operating in areas where you might not be
seen by other off-road vehicles.

WHAT CAN HAPPEN

You could be in a collision. You could be
injured.

HOW TO AVOID THE HAZARD

Always mount a caution flag on the ATV to
make you more visible. Watch carefully for
other vehicles.

Do not ride in areas posted “no trespassing”. Do
not ride on private property without getting per­mission.

7-20

Select a large, flat area off-road to become
familiar with your ATV. Make sure that this area
is free of obstacles and other riders. You should
practice control of the throttle, brakes, shifting
procedures, and turning techniques in this area
before trying more difficult terrain. Always avoid
riding on paved surfaces: the ATV is designed
for off-road use only, and handling maneuvers
are more difficult to perform on pavement.

Set the parking brake and follow the instruction
on page 6-1 to start the engine. Once it has
warmed up you are ready to begin riding your
ATV. As you get on the ATV, be sure not to
accidentally move the shift pedal. Remember
that the engine and exhaust pipe will be hot
when riding and afterwards; do not allow skin or
clothing to come in contact with these compo­nents.

With the engine idling, lift the shift pedal to the
1st gear position and then release the parking
brake. Apply the throttle slowly and smoothly.
The centrifugal clutch will engage and you will
start to accelerate. Once the ATV has attained
adequate speed, release the throttle and lift the
shift pedal to the 2nd gear position. Release the
shift pedal and apply the throttle smoothly. Use
this same procedure as you move into the high­er gears. Be sure to coordinate the use of the
throttle and shift pedal properly. If the throttle is
applied too abruptly or if the throttle is not
released during shifting, or if the shift pedal is
not released before applying the throttle, the
front wheels may lift off the ground resulting in a
loss of directional control. Avoid higher speeds
until you are thoroughly familiar with the opera­tion of your ATV.

7-21

cC

Do not shift gears without releasing the
throttle. Damage to the engine or drive train
may occur.

When slowing down or stopping, release the
throttle and apply the brakes smoothly and
evenly. As you slow down, shift to a lower gear.
Be sure that the engine has sufficiently slowed
before engaging a lower gear. Improper use of
the brakes or shifting can cause the tires to lose
traction, reducing control and increasing the
possibility of an accident.

q

WARNING

POTENTIAL HAZARD

Engaging a lower gear when the engine
speed is too high.

WHAT CAN HAPPEN

The wheels could stop rotating. This could
cause loss of control, an accident and
injury. It could also cause engine or drive
train damage.

HOW TO AVOID THE HAZARD

Make sure the engine has sufficiently
slowed before shifting to a lower gear.

7-22

TURNING YOUR ATV

To achieve maximum traction while riding off­road, the two rear wheels are mounted solidly
on one axle and turn together at the same
speed. Therefore, unless the wheel on the
inside of the turn is allowed to slip or lose some
traction, the ATV will resist turning. A special
turning technique must be used to allow the ATV
to make turns quickly and easily. It is essential
that this skill be learned first at low speed.

q

WARNING

POTENTIAL HAZARD

Turning improperly.

WHAT CAN HAPPEN

The ATV could go out of control, causing
a collision or overturn.

HOW TO AVOID THE HAZARD

Always follow proper procedures for turn­ing as described in this Owner’s Manual.
Practice turning at low speeds before
attempting to turn at faster speeds. Do not
turn at speeds too fast for your skills or
the conditions.

As you approach a curve, slow down and begin
to turn the handlebars in the desired direction.
As you do so, put your weight on the footboard
to the outside of the turn (opposite your desired
direction) and lean your upper body into the
turn. Use the throttle to maintain an even speed
through the turn. This maneuver will let the
wheel on the inside of the turn slip slightly,
allowing the ATV to make the turn properly.

7-23

Lean towards
inside of turn

Support your
weight on the
outer footrest

This procedure should be practiced at slow
speed many times in a large off-road area with
no obstacles. If an incorrect technique is used,
your ATV may continue to go straight. If the ATV
doesn’t turn, come to a stop and then practice
the procedure again. If the riding surface is slip­pery or loose, it may help to position more of
your weight over the front wheels by moving for­ward on the seat.

Once you have learned this technique you
should be able to perform it at higher speeds or
in tighter curves.

Improper riding procedures such as abrupt throt­tle changes, excessive braking, incorrect body
movements, or too much speed for the sharp­ness of the turn may cause the ATV to tip. If the
ATV begins to tip over to the outside while nego­tiating a turn, lean more to the inside. It may
also be necessary to gradually let off on the
throttle and steer to the outside of the turn to
avoid tipping over.
Remember: Avoid higher speeds until you are
thoroughly familiar with the operation of your
ATV.

7-24

CLIMBING UPHILL

Use proper riding techniques to avoid vehicle
overturns on hills. Be sure that you can maneu­ver your ATV well on flat ground before attempt­ing any incline and then practice riding first on
gentle slopes. Try more difficult climbs only after
you have developed your skill. In all cases avoid
inclines with slippery or loose surfaces, or obsta­cles that might cause you to lose control.

q

WARNING

POTENTIAL HAZARD

Operating on excessively steep hills.

WHAT CAN HAPPEN

The vehicle can overturn more easily on
extremely steep hills than on level sur­faces or small hills.

HOW TO AVOID THE HAZARD

Never operate the ATV on hills too steep
for the ATV or for your abilities.
Practice on smaller hills before attempting
large hills.

It is important when climbing a hill to make sure
that your weight is transferred forward on the
ATV. This can be accomplished by leaning for­ward and, on steeper inclines, standing on the
footboards and leaning forward over the handle­bars.

7-25

q

WARNING

POTENTIAL HAZARD

Climbing hills improperly.

WHAT CAN HAPPEN

Could cause loss of control or cause the
ATV to overturn.

HOW TO AVOID THE HAZARD

Always follow proper procedures for
climbing hills as described in this Owner’s
Manual.
Always check the terrain carefully before
you start up any hill.
Never climb hills with excessively slippery
or loose surfaces.
Shift your weight forward.
Never open the throttle suddenly or make
sudden gear changes. The ATV could flip
over backwards.

Never go over the top of any hill at high
speed. An obstacle, a sharp drop, or
another vehicle or person could be on the
other side of the hill.

OK

7-26

If you are climbing a hill and you find that you
have not properly judged your ability to make it
to the top, you should turn the ATV around while
you still have forward motion (provided you have
the room to do so) and go down the hill.

q

WARNING

POTENTIAL HAZARD

Improperly crossing hills or turning on
hills.

WHAT CAN HAPPEN

Could cause loss of control or cause the
ATV to overturn.

HOW TO AVOID THE HAZARD

Never attempt to turn the ATV around on
any hill until you have mastered the turn­ing technique 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
described in the Owner’s Manual.
Avoid hills with excessively slippery or
loose surfaces.
Shift your weight to the uphill side of the
ATV.

OK

7-27

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 uphill side. Physically turn the ATV
around and then descend the hill.

If you start to roll backwards, DO NOT use the
rear brake to stop or try to put the ATV in gear.
The ATV could easily tip over backwards.
Instead, apply the front brake gradually, or dis­mount the ATV immediately on the uphill side.

q

WARNING

POTENTIAL HAZARD

Stalling, rolling backwards or improperly
dismounting while climbing a hill.

WHAT CAN HAPPEN

Could result in the ATV overturning.

HOW TO AVOID THE HAZARD

Use proper gear and maintain steady
speed when climbing a hill.

If you lose all forward speed:

Keep weight uphill.
Apply the brakes.
Lock the parking brake, after you are
stopped.

If you begin rolling backwards:

Keep weight uphill.
Never apply the rear brake while rolling
backwards. Apply the front brake.

7-28

When fully stopped, apply the rear
brake as well, and then lock the parking

brake.
Dismount on uphill side or to a side if
pointed straight uphill. Turn the ATV
around and remount, following the proce­dure described in the Owner’s Manual.

7-29

RIDING DOWNHILL

When riding your ATV downhill, shift your weight
as far to the rear and uphill side of the ATV as
possible. Move back on the seat and sit with
your arms straight. Choose a low gear which will
allow the engine compression to do most of the
braking for you. Improper braking may cause a
loss of traction.
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.

Whenever possible, ride your ATV straight
downhill. 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 obstacles which may appear.

q

WARNING

POTENTIAL HAZARD

Going down a hill improperly.

WHAT CAN HAPPEN

Could cause loss of control or cause the
ATV to overturn.

HOW TO AVOID THE HAZARD

Always follow proper procedures for
going down hills as described in this
Owner’s Manual. 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 vehicle to lean sharply to
one side. Go straight down the hill where
possible.

7-30

OK

7-31

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 to cross a sloping surface.
Avoid slopes with slippery surfaces or rough ter­rain that may upset your balance.

As you travel across a slope, lean your body in
the uphill direction. It may be necessary to cor­rect the steering when riding on loose surfaces
by pointing the front wheels slightly uphill. When
riding on slopes be sure not to make sharp turns
either up or down hill.

If your ATV does begin to tip over, gradually
steer in the downhill direction if there are no
obstacles in your path. As you regain proper bal­ance, gradually steer again in the direction you
wish to travel.

q

WARNING

POTENTIAL HAZARD

Improperly crossing hills or turning on
hills.

WHAT CAN HAPPEN

Could cause loss of control or cause the
ATV to overturn.

HOW TO AVOID THE HAZARD

Never attempt to turn the ATV around on
any hill until you have mastered the turn­ing technique 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
described in the Owner’s Manual.
Avoid hills with excessively slippery or
loose surfaces.

CROSSING THROUGH SHALLOW WATER

The ATV can be used to cross slow moving,
shallow water of up to a maximum of 20 cm (7.9
inches) in depth. Before entering the water,
choose your path carefully. Enter where there is
no sharp drop off, and avoid rocks or other
obstacles which may be slippery or upset the
ATV. Drive slowly and carefully.

q

WARNING

POTENTIAL HAZARD

Operating this ATV through deep or fast
flowing water.

WHAT CAN HAPPEN

Tires may float, causing loss of traction
and loss of control, which could lead to an
accident.

HOW TO AVOID THE HAZARD

Never operate this ATV in fast flowing
water or in water deeper than that speci­fied in your Owner’s Manual.

Remember that wet brakes may have
reduced stopping ability. Test your brakes
after leaving water. If necessary, apply
them several times to let friction dry out
the linings.

7-34

Test your brakes after leaving the water. Do not
continue to ride your ATV without verifying that
you have regained proper braking ability.

cC

After riding your ATV in water, be sure to
drain the trapped water by removing the
check hose at the bottom of the air filter
case. Wash the ATV in fresh water if it has
been operated in salt water or muddy condi­tions.

q

1. Check hose

7-35

RIDING OVER ROUGH TERRAIN

Riding over rough terrain should be done with
caution. Look out for obstacles which could
cause damage to the ATV or could lead to an
upset or accident. Be sure to keep your feet
firmly mounted on the footboards at all times.
Avoid jumping the ATV as loss of control and
damage to the ATV may result.

q

WARNING

POTENTIAL HAZARD

Improperly operating over obstacles.

WHAT CAN HAPPEN

Could cause loss of control or a collision.
Could cause the ATV to overturn.

HOW TO AVOID THE HAZARD

Before operating in a new area, check for
obstacles.
Never attempt to ride over large obstacles,
such as large rocks or fallen trees. When
you go over obstacles, always follow
proper procedures as described in the
Owner’s Manual.

7-36

SLIDING AND SKIDDING

Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could lead
to an accident.

To reduce the tendency for the front wheels to
slide in loose or slippery conditions, positioning
your weight over the front wheels will sometimes
help.

If the rear wheels of your ATV start to slide side­ways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the
slide.

7-38

With practice, over a period of time, skill at con­trolled sliding can be developed. The terrain
should be chosen carefully before attempting
such maneuvers, since both stability and control
are reduced. Bear in mind that sliding maneu­vers should always be avoided on extremely
slippery surfaces such as ice, since all control
may be lost.

q

WARNING

POTENTIAL HAZARD

Skidding or sliding improperly.

WHAT CAN HAPPEN

You may lose control of this ATV. You
may also regain traction unexpectedly,
which may cause the ATV to overturn.

HOW TO AVOID THE HAZARD

Learn to safely control skidding or sliding
by practicing at low speeds and on level,
smooth terrain.
On extremely slippery surfaces, such as
ice, go slowly and be very cautious in
order to reduce the chance of skidding or
sliding out of control.

7-39

WHAT TO DO IF ...

This section is designed to be a reference guide
only. Be sure to read each section on riding
techniques completely.

WHAT TO DO ...

8 If your ATV doesn’t turn when you want it to:

Bring the ATV to a stop and practice the turn­ing maneuvers again. Be sure you are putting
your weight on the footboard to the outside of
the turn. Position your weight over the front
wheels for better control. (See pages 7-23–
7-24.)

8 If your ATV begins to tip while turning:

Lean more into the turn to regain balance. If
necessary, gradually let off the throttle and/or
steer to the outside of the turn. (See pages
7-23–7-24.)

8 If your ATV starts to slide sideways:

Steer in the direction of the slide if you have
the room.
Applying the brakes or accelerating is not rec­ommended until you have corrected the slide.
(See pages 7-38–7-39.)

8 If your ATV can’t make it up a hill you are try-

ing to climb:
Turn the ATV around if you still have forward
speed. If not, stop, dismount on the uphill side
of the ATV and physically turn the ATV
around. If the ATV starts to slip backwards
DO NOT USE THE REAR BRAKE - the ATV
may tip over on top of you. Instead, apply the
front brake or dismount the ATV on the uphill
side. (See pages 7-25–7-29.)

7-40

8 If your ATV is traversing a sloping surface:

Be sure to ride with your weight positioned
towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer
down the hill (if there are no obstacles in your
way) to regain balance. If you discover that
the ATV is going to tip over, dismount on the
uphill side. (See pages 7-32–7-33.)

8 If your ATV encounters shallow water:

Ride slowly and carefully through slow mov­ing water, watching for obstacles. Be sure to
let water drain from the ATV and CHECK
YOUR BRAKES FOR PROPER OPERATION
when you come out of the water. Do not con­tinue to ride your ATV until you have regained
adequate braking ability. (See pages 7-34–
7-35.)
