SAFETY INFORMATION

EBU17446
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. Take a Training Course.
Beginners should receive training from a certified instruc­tor. Contact an authorized ATV dealer or call 1­800-887-2887 to find out about the training courses nearest you.
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 streets.
Never operate an ATV on any public street, road
or highway, even a dirt or gravel one.
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
2
Page 14
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
2
manual.
Always keep both hands on the handlebars and
both feet on the footboards 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
Page 15
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.
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 be sure there are no obstacles or people
behind you when you operate in reverse. When it is safe to proceed in reverse, go slowly.
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.

WARNING
Avoid Carbon Monoxide Poisoning All engine exhaust contains carbon monoxide,
2
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 en­closed 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.
EWB02591
WARNING
When transporting the ATV in another vehicle, be sure it is kept upright and that the fuel cock is in the “OFF” position. Otherwise, fuel may leak out of the carburetor or fuel tank.

EWB00150
WARNING
Always ride at a slow speed when the ATV is in four-wheel-drive differential gear lock, and al­low extra time and distance for maneuvers. All wheels turn at the same speed when the dif­ferential is locked, so it takes more effort to turn the ATV. The effort needed to turn increas­es with the riding speed. You may lose control and have an accident if you cannot make a sharp enough turn for the speed you are trav­eling.

On-Command four-wheel-drive switch 2WD/4WD
EWB00163
WARNING
Always stop the ATV before changing from two-wheel drive to four-wheel drive and vice versa. The ATV handles differently in two­wheel drive than in four-wheel drive in some
4
circumstances. Changing from two-wheel drive to four-wheel drive or vice versa while moving may cause the ATV to unexpectedly handle differently. This could distract the oper­ator and increase the risk of losing control and of causing an accident.
This ATV is equipped with a switch to change from two-wheel drive to four-wheel drive and vice versa. Select the appropriate drive according to the ter­rain and the conditions.
“2WD (two-wheel drive): Power is supplied to
the rear wheels.
“4WD (four-wheel drive): Power is supplied to
the rear and front wheels.
To change from two-wheel drive to four-wheel drive, stop the ATV and push the switch in to the 4WD position. The four-wheel-drive indicator light “” comes on. To change from four-wheel drive to two-wheel drive, stop the ATV and push the switch in to the 2WD position.

EWB00131
WARNING
Always stop the ATV before changing from four-wheel drive to four-wheel-drive differen­tial gear lock or vice versa. The ATV handles differently in four-wheel drive than in differential gear lock in some circum­stances. Changing from four-wheel drive to dif­ferential gear lock or vice versa while moving may cause the ATV to handle differently unex­pectedly. This could distract the operator and increase the risk of losing control and causing an accident.
EWB00140
WARNING
Always ride at a slow speed when the ATV is in differential gear lock, and allow extra time and distance for maneuvers. All wheels turn at the same speed when the dif­ferential gear is locked, so it takes more effort to turn the ATV. The effort needed to turn in­creases with the riding speed. You may lose
control and have an accident if you cannot make a sharp enough turn for the speed you are traveling.
This ATV is equipped with a switch allowing you to lock the differential gear when in four-wheel drive. Select the appropriate switch position according to the terrain and the conditions.
“4WD (four-wheel drive): Power is supplied to
the rear and front wheels.
“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
If the differential gear lock is not engaging prop-
erly, turn the handlebar back and forth to help it engage.
Riding before the differential gear lock is proper-
ly engaged will cause the vehicle speed to be limited until engagement is complete.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit­ed to 31 km/h (19 mi/h). However, if conditions require full engine power to be available, push
and hold the override switch to disable the differ­ential gear lock speed limiter. (See page 4-6 for a detailed explanation of this switch.)
EBU18282

Throttle lever

Once the engine is running, pushing the throttle le­ver will increase the engine speed. Regulate the speed of the ATV by varying the throttle position. Because the throttle is spring­loaded, the ATV will decelerate, and the engine will return to an idle any time the throttle lever is re­leased.

4-10
Page 30
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.
EBU18323

Speed limiter

Your ATV is equipped with an adjustable speed limiter. The speed limiter keeps the throttle from
4
fully opening, even when the throttle lever is pushed to the maximum.
1. Loosen the locknut.
2. To increase the maximum engine power avail­able and the maximum speed of the ATV, turn the adjusting screw in direction (a). To de­crease the maximum engine power available and the maximum speed of the ATV, turn the adjusting screw in direction (b). Do not turn the adjusting screw out more than 12 mm (0.47 in) or the throttle cable could be dam­aged. Always make sure the throttle lever free play is adjusted to 3.0–5.0 mm (0.12–0.20 in). (See page 8-27.) WARNING! Improper ad-
justment of the speed limiter and throttle could cause throttle cable damage or im­proper throttle operation. You could lose control, resulting in an accident.

TIP
For ATVs equipped with an odometer or an hour
meter, follow the figures given in km (mi) or the 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.
6-5
Page 53
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 products that these aftermarket companies pro­duce. Therefore, Yamaha can neither endorse nor recommend the use of accessories not sold by
6-7
Page 55
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 after­market products or having other modifications performed to your ATV that change any of the ve­hicles 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.
EBU21001
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.
Cargo or a trailer can change the stability and han­dling of an ATV. You must use common sense and good judgment when carrying cargo or towing a trailer. Keep the following points in mind:
6-8
6
Page 56
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):
210.0 kg (463 lb)
Front carrier :
40.0 kg (88 lb)
Rear carrier:
80.0 kg (176 lb)
6
Storage compartment:
2.0 kg (4 lb)
Trailer hitch:
Pulling load (total weight of trailer and car­go):
4900 N (500 kgf, 1102 lbf) Tongue weight (vertical weight on trailer hitch point):
147 N (15 kgf, 33 lbf)
Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath­room scale. Put the tongue of the loaded trailer on the scale with the tongue at hitch height. Ad­just the load in the trailer, if necessary, to reduce
the weight on the hitch. If you are carrying cargo and towing a trailer, include 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.

Loading and accessories
EWB01462
WARNING
Improper loading or towing can increase the risk of loss of control, an overturn, or other ac­cident. To reduce the risk of an accident:
Do not exceed the maximum loading limits
for the vehicle (see MAXIMUM LOADING
LIMIT in this section or vehicle labeling).
Keep weight on racks centered side to side,
and as low as possible. Be sure cargo is se-
cured – a loose load could change handling
unexpectedly.
Make sure the load does not interfere with
your control or ability to see where you are
going.
Tie down cargo in the trailer securely. Make
sure cargo in the trailer cannot move around.
A shifting load can cause an accident.
Reduce speed and allow more room to stop.
A heavier vehicle takes longer to stop.
Avoid hills and rough terrain. Choose terrain
carefully. Use extreme caution when towing
or carrying a load on inclines.
Turn gradually and go slowly.
Take extra precautions when driving with a load or trailer. Follow these instructions and always use common sense and good judgment when carrying cargo or towing a trailer.

[EWB01061]
7-11
Page 69
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. 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, 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.
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 control.
[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 Owners 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 while riding off-road, 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,
7-12
7
Page 70
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 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
1. Lean towards inside of turn.
2. Support your weight on the outer footboard.
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.
7-13
Page 71
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 Owners 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.
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 tech­nique as described in the Owners 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
Page 72
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. For more traction and control for climbing steeper and/or rougher slopes, select 4WD or 4WD-LOCK (DIFF. LOCK). Travel fast enough to maintain momentum, but not so fast that you cannot react to changes in the terrain as you climb.
7
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. 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.
7-15
Page 73
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. If you start to roll backwards, DO NOT apply either brake abruptly. If you are in “2WD”, apply only the front brake. When fully stopped, apply the rear brake as well, and then lock the parking brake. If you are in “4WD” or 4WD-LOCK, because all wheels are interconnected by the drive train, ap­plying either brake will brake all wheels, therefore, avoid sudden application of either the front or rear brake as the wheels on the uphill side could come off the ground. The ATV could easily tip over back­wards. Apply both the front and rear brakes gradu­ally. When fully stopped, lock the parking brake and 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 Owners 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.

RIDING DOWNHILL

EWB01621
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 Owners Manual.
Always check the terrain carefully before
you start down any hill.
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
7
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. Apply brakes gradual­ly. If in “2WD”, apply only the rear brake.
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. Engine compression will do most of the braking for you. For maximum engine compres­sion braking effect, change to “4WD before begin- ning to descend the hill. 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. When this ATV is in “4WD, all wheels (front and rear) are interconnected 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 either 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 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.

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 Owners 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 tech­nique as described in the Owners 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 Owners 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 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.
[EWB02621]
1. Air filter case check hose
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. NOTICE: Undrained
water can cause damage or improper opera­tion.
[ECB00841]
Wash the ATV in fresh water if it has been operat­ed in salt water or muddy conditions.

RIDING OVER ROUGH TERRAIN

EWB01651
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 Owners 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-
7-20

cident. 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.

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,
7
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.
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
Page 79
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 footboard 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 IF THE ATV IS IN “2WD” – the ATV may tip over on top of you. Dismount the ATV on the uphill side. (See page 7-14.)
7
7-22
Page 80
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.)

Checking the spark plug

The spark plug is an important engine component, which is easy to check. Since heat and deposits will cause any spark plug to slowly erode, the spark plug should be removed and checked in accor­dance with the periodic maintenance and lubrica­tion chart. In addition, the condition of the spark plug can reveal the condition of the engine.
To remove the spark plug
1. Remove the spark plug cap.
1. Spark plug cap
2. Remove the spark plug as shown, with the spark plug wrench included in the owners tool kit.

8-9
Page 90
1. Spark plug wrench
To check the spark plug
1. Check that the porcelain insulator around the
8
center electrode of the spark plug is a medi­um-to-light tan (the ideal color when the ATV is ridden normally).
TIP
If the spark plug shows a distinctly different color, the engine could be operating improperly. Do not attempt to diagnose such problems yourself. In­stead, have a Yamaha dealer check the ATV.
2. Check the spark plug for electrode erosion and excessive carbon or other deposits, and replace it if necessary.
Specified spark plug:
NGK/DR8EA
3. Measure the spark plug gap with a wire thick­ness gauge and, if necessary, adjust the gap to specification.
1. Spark plug gap
Spark plug gap:
0.6–0.7 mm (0.024–0.028 in)
8-10
Page 91
To install the spark plug
1. Clean the surface of the spark plug gasket and its mating surface, and then wipe off any grime from the spark plug threads.
2. Install the spark plug with the spark plug wrench, and then tighten it to the specified torque.
EBU2327E

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 cleaned at the intervals speci­fied in the periodic maintenance and lubrication chart.
Tightening torque:
Spark plug:
18 Nm (1.8 m·kgf, 13 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.
3. Install the spark plug cap.
To check the engine oil level
1. Place the ATV on a level surface.
2. Check the engine oil level on a cold engine.
TIP
If the engine was started before checking the oil level, be sure to warm up the engine sufficiently, and then wait at least ten minutes until the oil set­tles for an accurate reading.
3. Remove the engine oil filler cap, and then wipe the engine oil dipstick off with a clean rag.
