SAFETY INFORMATION

EBU26685
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. Take a training course. Beginners should receive training from a certified instruc­tor. Contact an authorized ATV dealer 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.
SAFETY INFORMATION
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.This vehicle is intended for off-road use only. Do
not operate on any paved surfaces such as: sidewalks, driveways, parking lots, paved roads, public streets or other 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.
2-1
Page 21
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.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 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
2
2-2
Page 22
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
2
backwards when climbing a hill. To avoid stall­ing, use the 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.
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 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.
Do not operate your ATV during darkness un-
less it is equipped with a properly functioning headlight. Off-road riding is inherently danger­ous and additionally, off-road trails do not have streetlights to guide you.
2-3
Page 23
Never maintain an ATV without proper knowl-
edge. Contact an authorized ATV dealer to in­form you on basic ATV maintenance. Certain maintenance can only be carried out by certified staff.
In the event of an accident
1. If serious injuries are incurred, you may be safer staying next to your vehicle; it may shield you from oncoming riders. Depending on your injuries and position in the trail; you must make a judgment call as to whether you should move to a position off the trail. If you have sustained head, neck, or back injuries, or cannot feel your limbs, you should not move. Keep your helmet on and remain mo­tionless. Lie down next to your vehicle and wait for help.
2. If less serious injuries are incurred and you can walk, then move to a position off the trail. Check yourself for injuries and apply first aid as needed.
3. If your injuries are light, when safe to do so, move your vehicle off the trail to avoid colli­sions with oncoming riders. Check for injuries and apply first aid as necessary. If you can physically operate your vehicle, inspect your
vehicle. If the vehicle is in safe operating con­dition and you can safely operate it, restart it and ride gently back to camp or other known location where you can receive medical at­tention. If necessary, contact your riding party or local authorities to let them know where you are and what has happened.
In the event of a breakdown
1. If your vehicle will not restart or is not in safe operating condition, turn off the main switch and engine stop switch. If the breakdown oc­curs at twilight or night, leave the main switch on so that your lights may warn other riders of your stopped vehicle.
2. Get out of danger. Check for oncoming vehi­cles and when safe, push your vehicle to the side of the trail or even off the main trail to avoid any possible collisions with oncoming riders. If you cannot move your vehicle by yourself, when safe, walk to the nearest van­tage point and signal an oncoming rider to help you push your vehicle to a safe place off the trail.
3. Inspect your vehicle for any immediate haz­ardous conditions. The most obvious hazard­ous conditions are leaking fuel and
2-4
2
Page 24
ungrounded or broken wiring. Visually check for broken wiring and leaking fuel. Leaking fuel can be confirmed by the odor of gasoline.
4. Once immediate safety hazards are con-
2
firmed not to exist, you may remove your hel­met to more closely inspect your vehicle. Check for external signs of wear, broken parts, fluid leaks, cracks in the frame, sus­pension damage, wheel damage, and so on. Fuel, oil, and coolant usually give off a notice­able odor.
5. If your vehicle will not restart or if it is unsafe to ride, then turn off all vehicle systems (en­gine stop switch, main switch, and fuel cock), and then signal or go for help.
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 vehicle 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 guidelines in mind, as well as those provided un­der “Loading” when mounting accessories. Never install accessories that would impair the
performance of your ATV. Carefully inspect the accessory before using it to make sure that it does not in any way reduce ground clearance, limit suspension travel, steering travel or control operation.
Accessories fitted to the ATV can create insta-
bility due to improper weight distribution.
Bulky or large accessories may seriously affect
the stability of the ATV.
Certain accessories can displace the operator
from his or her normal riding position. This im­proper position limits the freedom of movement of the operator and may limit control ability, therefore, such accessories are not recom­mended.
Use caution when adding electrical accesso-
ries. If electrical accessories exceed the capac­ity of the ATV’s electrical system, an electric failure could result, which could cause a dan­gerous loss of lights or engine power.

WARNING
EWB00073
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 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.

Speed limiter

Your ATV is equipped with an adjustable speed limiter. The speed limiter keeps the throttle from 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 2.0–4.0 mm (0.08–
0.16 in). (See page 8-28.) WARNING! Im-
proper adjustment of the speed limiter and throttle could cause throttle cable damage or improper throttle operation. You could lose control, resulting in an accident.

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. 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.

Genuine Yamaha Accessories
Choosing accessories for your ATV is an impor­tant decision. Genuine Yamaha Accessories, which are available only from a Yamaha dealer,
6-6
Page 69
have been designed, tested, and approved by
WARNING
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 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 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.

curely 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-
6
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.

iar 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.

[ECB01072]
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

EWB01772
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.
7-11
7
Page 82
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
7
turn. This maneuver will let the wheel on the inside of the turn slip slightly, allowing the ATV to make the turn properly.
1. Lean towards inside of turn.
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.
7-12
Page 83
Once you have learned this technique, you should
WARNING
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

EWB01592
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.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 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.

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.
7-14
Page 85
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.
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.

WARNING

RIDING DOWNHILL

EWB01132
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.
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 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.
7-16
Page 87
Whenever possible, ride your ATV straight down-
WARNING
hill. Avoid sharp angles which could allow the ATV to tip or roll over. Carefully choose your path and ride no faster than you will be able to react to ob­stacles which may appear.

CROSSING A SLOPE

EWB01633
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 tech­nique 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.
7
7-17
Page 88
As you travel across a slope, lean your body in the
WARNING
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

EWB01642
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 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.
7-18
Page 89
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
reduced stopping ability, which could cause loss of control.
[EWB02622]
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 opera-
[ECB00842]
tion.
Wash the ATV in fresh water if it has been operat­ed in salt water or muddy conditions.

RIDING OVER ROUGH TERRAIN

7
EWB01652
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
accident. 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

EWB01663
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.
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.
7-20
Page 91
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.
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 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 7-11.) 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 7-11.) 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
7
recommended until you have corrected the
slide. (See page 7-20.) 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.)
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 7-17.)
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 page 7-18.)

PERIODIC MAINTENANCE AND ADJUSTMENT

EBU21675
Periodic inspection, adjustment, and lubrication will keep your vehicle in the safest and most effi­cient condition possible. Safety is an obligation of the vehicle owner/operator. The most important points of vehicle inspection, adjustment, and lu­brication are explained on the following pages.
EWB01842
Failure to properly maintain the vehicle or per­forming maintenance activities incorrectly may increase your risk of injury or death during ser­vice or while using the vehicle. If you are not fa­miliar with vehicle service, have a Yamaha dealer perform the service.
EWB02563
Turn off the engine when performing mainte­nance unless otherwise specified. A running engine has moving parts that can
catch on body parts or clothing and electri­cal parts that can cause shocks or fires.
Running the engine while servicing can lead
to eye injury, burns, fire, or carbon monoxide poisoning - possibly leading to death. See page 2-6 for more information about carbon monoxide.
EWB02691
Brake discs, calipers, drums, and linings can become very hot during use. To avoid possible burns, let brake components cool before touching them.
The intervals given in the periodic maintenance charts should be considered as a general guide under normal riding conditions. However, DE­PENDING ON THE WEATHER, TERRAIN, GEO­GRAPHICAL LOCATION, AND INDIVIDUAL USE, THE MAINTENANCE INTERVALS MAY NEED TO BE SHORTENED.
