SAFETY INFORMATION
EBU29371
2
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:
● Read this manual and all labels carefully and fol-
low the operating procedures described.
● Never operate an ATV without proper training or
instruction.
● Always follow the age recommendation:
– A child under 16 years old should never operate an ATV with engine size greater than 90 cc.
● Never allow a child under age 16 to operate an
ATV without adult supervision, and never allow
continued use of an ATV by a child if he or she
does not have the abilities to operate it safely.
● Never carry a passenger on an ATV.
● Always avoid operating an ATV on any paved
surfaces, including sidewalks, driveways, parking lots and paved streets.
● Never operate an ATV on any paved street,
paved road or motorway.
● Watch carefully for other vehicles when operat-
ing on unpaved public streets or roads. Make
sure you know your country’s laws and regulations before you ride on unpaved public streets
or roads.
● Never operate an ATV without wearing an ap-
proved motorcycle helmet that fits properly. You
should also wear eye protection (goggles or face
shield), gloves, boots, a long-sleeved shirt or a
jacket, and long pants.
● Never consume alcohol or drugs before or while
operating this ATV.
● Never operate at speeds too fast for your skills
or the riding conditions. Always go at a speed
that is proper for the terrain, visibility, operating
conditions, and your experience.
● Never attempt wheelies, jumps, or other stunts.
2-1
● 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.
● Always keep both hands on the handlebars and
both feet on the footrests of the ATV during operation.
● Always go slowly and be extra careful when op-
erating on unfamiliar terrain. Always be alert to
changing terrain conditions when operating the
ATV.
● 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.
● Always follow proper procedures for turning as
described in this manual. Practice turning at low
speeds before attempting to turn at faster
speeds and never turn at excessive speeds.
● Never operate the ATV on hills too steep for the
ATV or for your abilities. Practice on smaller hills
before attempting larger hills.
● 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.
● 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.
● 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.
● Always use proper procedures if you stall or roll
backwards when climbing a hill. To avoid stalling, use the proper gear and maintain a steady
2
2-2
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 up-
2
hill. Turn the ATV around and remount, following
the procedure described in this manual.
● 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.
● 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.
● Never operate an ATV in fast flowing water or in
water deeper than that recommended in this
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.
● Always use the size and type of tires specified in
this manual.
● Always maintain proper tire pressure as de-
scribed in this manual.
● Never modify an ATV through improper installa-
tion or use of accessories.
● 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.
EWB00071
WARNING
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide,
a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nausea, confusion, and eventually death.
Carbon Monoxide is a colorless, odorless,
tasteless gas which may be present even if you
do not see or smell any engine exhaust. Deadly
levels of carbon monoxide can collect rapidly
and you can quickly be overcome and unable
to save yourself. Also, deadly levels of carbon
monoxide can linger for hours or days in en-
2-3
closed or poorly ventilated areas. If you experience any symptoms of carbon monoxide
poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.
● Do not run engine indoors. Even if you try to
ventilate engine exhaust with fans or open
windows and doors, carbon monoxide can
rapidly reach dangerous levels.
● Do not run engine in poorly ventilated or par-
tially enclosed areas such as barns, garages,
or carports.
● Do not run engine outdoors where engine
exhaust can be drawn into a building
through openings such as windows and
doors.

To decelerate
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.
EWB00710
WARNING
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a lower gear when the engine speed is too high
could make the wheels stop rotating and lose
traction. This could cause loss of control, an
accident and injury. It could also cause engine
or drive train damage.

Engine break-in
TIP
● For ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or the
6
figures given in hours.
● For ATVs not equipped with an odometer or
hour meter, follow the figures given in hours.
There is never a more important period in the life of
your engine than the first 320 km (200 mi) or 20
hours of riding. For this reason, you should read
the following material carefully.
Since the engine is brand new, do not put an excessive load on it for the first 320 km (200 mi) or 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 that might result in engine overheating must be avoided.
0–160 km (0–100 mi) or 0–10 hours
Avoid prolonged operation above 1/2 throttle. Vary
the speed of the ATV regularly. Do not operate it at
one set throttle position.
160–320 km (100–200 mi) or 10–20 hours
Avoid prolonged operation above 3/4 throttle. Rev
the engine through the gears freely, but do not use
full throttle at any time.
320 km (200 mi) or 20 hours and beyond
The ATV can now be operated normally.

Accessories and loading
EBU20921
Genuine Yamaha Accessories
Choosing accessories for your ATV is an important
decision. Genuine Yamaha Accessories, which
are available only from a Yamaha dealer, have
been designed, tested, and approved by Yamaha
for use on your ATV. Many companies with no connection to Yamaha manufacture parts and accessories or offer other modifications for Yamaha
vehicles. Yamaha is not in a position to test the
6
products that these aftermarket companies produce. Therefore, Yamaha can neither endorse nor
recommend the use of accessories not sold by
Yamaha or modifications not specifically recommended by Yamaha, even if sold and installed by
a Yamaha dealer.
Aftermarket parts, accessories, and modifications
While you may find aftermarket products similar in
design and quality to genuine Yamaha Accessories, recognize that some aftermarket accessories
or modifications are not suitable because of potential safety hazards to you or others. Installing after-
market products or having other modifications
performed to your ATV that change any of the vehicle’s design or operation characteristics can put
you and others at greater risk of serious injury or
death. You are responsible for injuries related to
changes in the vehicle.
Keep the following in mind when considering an
accessory or operating an ATV which has accessories.
● 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.
● Do not mount an accessory where it could inter-
fere 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.
● Use extra caution when riding an ATV with ac-
cessories. The ATV may handle differently than
it does without accessories.

EBU20941
Loading
EWB00820
WARNING
Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or towing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and securely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater distance for braking.
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 as the stability and handling of an ATV
can be changed. When adding accessories, keep
the following points in mind:
● Never exceed the weight limits shown. An over-
loaded ATV can be unstable.
MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
100.0 kg (220 lb)
● If you are carrying cargo and towing a trailer, in-
clude the tongue weight in the maximum ATV
load limit.
● Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.
● Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
● Make sure the load does not interfere with con-
trols or your ability to see where you are going.
● 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.
● Allow more braking distance. A heavier ATV
takes longer to stop.
● Avoid making sharp turns unless at very slow
speeds.
● Avoid hills and rough terrain. Choose terrain
carefully. Added weight affects the stability and
handling of the ATV.

7-10
7 Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting permission.
Select a large, flat, unpaved area 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.
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. With the engine idling, pull the
clutch lever to disengage the clutch and shift into
1st gear, and then release the parking brake. Open
the throttle gradually, and at the same time, release the clutch lever slowly. Once the ATV has attained adequate speed, release the throttle lever
and at the same time, quickly pull in the clutch lever and shift into 2nd gear. Open the throttle part
way and gradually release the clutch. WARNING!
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 con-
7-11
trol.
[EWB02631] NOTICE: Do not shift gears without
releasing the throttle. Damage to the engine or
drive train may occur.
[ECB01071]
Use this same procedure as you move into the
higher gears. Be sure to coordinate the use of the
throttle and shift pedal properly.
Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.
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.
TURNING YOUR ATV
EWB01771
WARNING
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. ATV could go
out of control, causing a collision or overturn.
To achieve maximum traction on unpaved surfaces, the two rear wheels 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.
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 footrest 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
7-12
1. Lean towards inside of turn.
7
2. Support your weight on the outer footrest.
This procedure should be practiced at slow speed
many times in a large unpaved 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.
CLIMBING UPHILL
EWB01591
WARNING
Climbing hills improperly can cause overturns
or loss of control. Use proper riding techniques described in this Owner’s Manual.
● Never operate the ATV on hills too steep for
the ATV or for your abilities. The ATV can
overturn more easily on extremely steep hills
than on level surfaces or small hills.
● Always check the terrain carefully before
you start up any hill. Never climb hills with
excessively slippery or loose surfaces.
● Shift your weight forward.
7-13
● 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.
● Never 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 pos-
sible. When crossing the side of a hill, shift
your weight to the uphill side of the ATV.
7
7-14
7
Do not attempt to climb hills until you have mastered basic maneuvers on flat ground. Always
check the terrain carefully before attempting any
hill. In all cases avoid inclines with slippery or loose
surfaces, or obstacles that might cause you to lose
control.
To climb a hill, you need traction, momentum, and
steady throttle. Travel fast enough to maintain momentum, but not so fast that you cannot react to
changes in the terrain as you climb.
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 footrests and
leaning forward over the handlebars. Whenever
possible, ride straight up hills.
Slow down when you reach the crest of the hill if
you cannot see clearly what is on the other side –
there could be another person, an obstacle, or a
sharp drop-off. Use common sense and remember
that some hills are too steep for you to climb or descend.
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.
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.
7-15
If you start to roll backwards, DO NOT apply the
rear brake, and apply the front brake gradually.
The ATV could easily tip over backwards. When
fully stopped, apply the rear brake as well, and
then lock the parking brake. Dismount the ATV immediately on the 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. WARNING! Stalling, rolling backwards
or improperly dismounting while climbing a hill
could result in ATV overturning. If you cannot
control the ATV, dismount immediately on the
uphill side.
[EWB01802]

RIDING DOWNHILL
EWB01131
WARNING
Going down a hill improperly could cause
overturns or loss of control. Always follow
proper procedures for going down hills as described in this Owner’s Manual.
● Always check the terrain carefully before
you start down any hill.
7-16
● Never operate the ATV on hills too steep for
the ATV or for your abilities. The ATV can
overturn more easily on extremely steep hills
than on level surfaces or small hills.
● Shift your weight backward and to the up
side of the hill.
● 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 possible.
● Improper braking can cause the wheels on
the uphill side to come off the ground or
cause loss of traction. Gradually apply only
7
the rear brake when going 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.
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. Gradually apply only the rear brake.
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.
7-17
CROSSING A SLOPE
EWB01632
WARNING
Improperly crossing hills or turning on hills
could cause loss of control or cause the ATV to
overturn.
● Always follow proper procedures as de-
scribed in the Owner’s Manual.
● Avoid hills with excessively slippery or loose
surfaces.
● Avoid crossing the side of a steep hill.
● 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 tech-
nique as described in the Owner’s Manual on
level ground. Be very careful when turning
on any hill.
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.

CROSSING THROUGH SHALLOW WATER
EWB01641
WARNING
Operating this vehicle through deep or fastflowing water can lead to loss of control or an
overturn. To reduce your risk of drowning or
other injuries, use care when crossing through
water. Never operate this ATV water deeper
than the depth specified in your Owner’s Manual, as tires may float, increasing the risk of an
overturn.
The ATV can be used to cross slow moving, shallow water of up to a maximum of 35 cm (14 in) in
7
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.
Test your brakes after leaving the water. If necessary, apply them several times to let friction dry out
the linings. Do not continue to ride your ATV without verifying that you have regained proper braking
ability. WARNING! Wet brakes may have re-
duced stopping ability, which could cause loss
of control.

WARNING
Riding improperly over obstacles could cause
loss of control or a collision. 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.
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 ac-

cident. Be sure to keep your feet firmly mounted on
the footrests at all times. Avoid jumping the ATV as
loss of control and damage to the ATV may result.
SLIDING AND SKIDDING
EWB01662
WARNING
Skidding or sliding improperly may cause you
to lose control of this ATV. You may also regain traction unexpectedly, which may cause
the ATV to overturn.
● Learn to safely control skidding or sliding by
practicing at low speeds and on level,
smooth terrain.
7
● 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.
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.
7-21
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.
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...
● 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 footrest to the outside of the turn.
Position your weight over the front wheels for
better control. (See page 7-12.)
● 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 page 7-12.)
● 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 page 7-21.)
● If your ATV can’t make it up a hill you are trying
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. Dismount the ATV on the uphill side.
(See page 7-13.)
7
7-22
● 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 page 7-18.)
● 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
7
ride your ATV until you have regained adequate
braking ability. (See page 7-19.)

dance with the periodic maintenance and lubrication chart. In addition, the condition of the spark
plug can reveal the condition of the engine.
The porcelain insulator around the center electrode of the spark plug should be a medium-to-light
tan (the ideal color when the vehicle is ridden normally). If the spark plug shows a distinctly different
color, the engine could be operating improperly.
11
Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the vehicle.
If the spark plug shows signs of electrode erosion
and excessive carbon or other deposits, it should
be replaced.
Specified spark plug:

NGK/CR8E
EBU29441
Checking the spark plug
The spark plug is an important engine component,
which should be checked periodically, preferably
by a Yamaha dealer. Since heat and deposits will
cause any spark plug to slowly erode, the spark
plug should be removed and checked in accor-
Before installing the spark plug, the spark plug gap
should be measured with a wire thickness gauge
and, if necessary, adjusted to specification.
8-13
1. Spark plug gap
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
8
Clean the surface of the spark plug gasket and its
mating surface, and then wipe off any grime from
the spark plug threads.
Tightening torque:
Spark plug:
12.5 Nm (1.25 m·kgf, 9.0 ft·lbf)
TIP
If a torque wrench is not available when installing
the spark plug, a good estimate of the correct
torque is 1/4–1/2 turn past finger tight. However,
the spark plug should be tightened to the specified
torque as soon as possible.
EBU29495
Engine oil and oil filter element
The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter element replaced at the intervals specified in the periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the engine oil
has reached a normal temperature of 40 °C
(104 °F), let it continue to idle for ten seconds
or more, and then turn the engine off.
