AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE. An ATV handles differently from other vehicles including motorcycles and cars. A collision or rollover can occur quickly, even during routine maneuvers such as turning and riding on hills or over obstacles, if you fail to take proper precautions. SEVERE INJURY OR DEATH can result if you do not follow these instructions: 8 Read this manual and all labels carefully and follow the operating procedures described. 8 Never operate an ATV without proper training or instruction. Take a Training Course.

Beginners should receive training from a certified instructor. Contact an authorized ATV deal- er or call 1-800-447-4700 to find out about the training courses nearest you.

8 Always follow the age recommendation: - A child under 16 years old should never operate an ATV with engine size greater than 90cc.

8 Never allow a child under age 16 to operate an ATV without adult supervision, and never allow continued use of an ATV by a child if he or she does not have the abilities to operate it safely.

8 Never carry a passenger on an ATV.

q SAFETY INFORMATION 2

3FA-9-1C-1 4/15/0 10:47 PM Page 2-1

8 Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, park- ing lots and streets.

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

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

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

proper for the terrain, visibility and operating conditions, and your experience. 8 Never attempt wheelies, jumps, or other stunts. 8 Always inspect your ATV each time you use it to make sure it is in safe operating condition.

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

8 Always keep both hands on the handlebars and both feet on the footboards of the ATV dur- ing operation.

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

3FA-9-1C-1 4/15/0 10:47 PM Page 2-2

2-3

8 Never operate on excessively rough, slippery or loose terrain until you have learned and practiced the skills necessary to control the ATV on such terrain. Always be especially cau- tious on these kinds of terrain.

8 Always follow proper procedures for turning as described in this manual. Practice turning at low speeds before attempting to turn at faster speeds. Do not turn at excessive speed.

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

8 Always follow proper procedures for climbing hills as described in this manual. Check the ter- rain 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. Never go over the top of a hill at high speed.

8 Always follow proper procedures for going down hills and for braking on hills as described in this manual. Check the terrain carefully before you start down any hill. Shift your weight backward. Never go down a hill at high speed. Avoid going down a hill at an angle that would cause the vehicle to lean sharply to one side. Go straight down the hill where possible.

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

3FA-9-1C-1 4/15/0 10:47 PM Page 2-3

2-4

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

8 Always check for obstacles before operating in a new area. Never attempt to operate over large obstacles, such as large rocks or fallen trees. Always follow proper procedures when operating over obstacles as described in this manual.

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

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

8 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.

8 Always use the size and type tires specified in this manual. Always maintain proper tire pres- sure as described in this manual.

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

Throttle lever

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

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.

4-4

POTENTIAL HAZARD

Malfunction of throttle.

WHAT CAN HAPPEN

The throttle could be hard to operate,

making it difficult to speed up or slow

down when you need to. This could cause

an accident.

HOW TO AVOID THE HAZARD

Check the operation of the throttle lever

before you start the engine. If it does not

work smoothly, check for the cause.

Correct the problem before riding the

ATV. Consult a Yamaha dealer if you can't

find or solve the problem yourself.

Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number ([R+M]/2) of 86 or higher, or research octane number of 91 or higher. If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel. Unleaded fuel will give you longer spark plug life and reduced maintenance cost. If unlead- ed gasoline is not available, then leaded reg- ular gasoline can be used.

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

5-4

POTENTIAL HAZARD

Improper care when refueling.

WHAT CAN HAPPEN

Fuel can spill, which can cause a fire and

severe injury.

Fuel expands when it heats up. If the fuel

tank is overfilled, fuel could spill out due

to heat from the engine or the sun.

EBU00209

Engine break-in

There is never a more important period in the life of your machine than the period between zero and 20 hours. For this reason, we ask that you carefully read the following material. Because the engine is brand new, you must not put an excessive load on it for the first several hours of running. During the first 20 hours, the vari- ous parts in the engine wear and polish themselves to the correct operating clear- ances. During this period, prolonged full throttle operation or any condition which might result in excessive engine heating must be avoided. However, momentary (2 ~ 3 sec- onds maximum) full throttle operation under load does not harm the engine.

Each full throttle acceleration sequence should be followed with a substantial rest period for the engine by cruising at lower r/min so the engine can rid itself of the tem- porary build up of heat. If any abnormality is noticed during this peri- od, consult a Yamaha dealer.

1. 0 ~ 10 hours: Avoid continuous operation above half throttle. Allow a cooling off period of five to ten minutes after every hour of opera- tion. Vary the speed of the machine from time to time. Do not operate it at one set throttle position.

Accessories and loading

EBU00222

Accessories

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

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

8 Accessories should be rigidly and securely mounted. An accessory which can shift position or come off while you are riding could affect your ability to control the ATV.

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

8 Use extra caution when riding an ATV with accessories. The ATV may handle differ- ently than it does without accessories.

Loading

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

overloaded ATV can be unstable.

8 Load cargo on the carriers as close to the center of the vehicle as possible. Put cargo at the rear of the front carrier and at the front of the rear carrier. Center the load from side to side.

8 Tie down cargo securely to the carriers. Make sure cargo in the trailer cannot move around. A shifting load can cause an acci- dent.

8 Make sure the load does not interfere with controls or your ability to see where you are going.

8 Ride more slowly than you would without a load. The more weight you carry, the slower you should go.

8 Allow more braking distance. A heavier vehicle takes longer to stop.

8 Avoid making sharp turns unless at very slow speeds.

8 Avoid hills and rough terrain. Choose ter- rain carefully. Added weight affects the stability and handling of the ATV.

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

Do not ride in areas posted no trespassing. Do not ride on private property without get- ting permission.

POTENTIAL HAZARD

Operating in areas where you might not

be seen by other off-road vehicles.

qWARNING

WHAT CAN HAPPEN

You could be in a collision. You could be

injured.

HOW TO AVOID THE HAZARD

Always mount a caution flag on the

machine to make you more visible. Watch

carefully for other vehicles.

3FA-9-1C-2 4/15/0 10:50 PM Page 7-20

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

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

With the engine idling, return the starter knob to the closed position and shift the drive select lever into the forward position. Then release the parking brake. Apply the throttle slowly and smoothly. The centrifugal clutch will engage and you will start to accel- erate. If the throttle is applied too abruptly, the front wheels may lift off the ground resulting in a loss of directional control. Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.

When slowing down or stopping, release the throttle and apply the brakes smoothly and evenly. Improper use of the brakes can cause the tires to lose traction, reducing control and increasing the possibility of an accident.

TURNING YOUR ATV

To achieve maximum traction while riding off-road, the two rear wheels are mounted solidly on one axle and turn together at the same speed. Therefore, unless the wheel on the inside of the turn is allowed to slip or lose some traction, the ATV will resist turn- ing. 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 throt- tle 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.

POTENTIAL HAZARD

Turning improperly.

WHAT CAN HAPPEN

ATV could go out of control, causing a col-

lision or overturn.

qWARNING

HOW TO AVOID THE HAZARD

Always follow proper procedures for turn-

ing 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.

3FA-9-1C-2 4/15/0 10:50 PM Page 7-22

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 doesnt turn, come to a stop and then practice the procedure again. If the rid- ing 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 out- side while negotiating a turn, lean more to the inside. It may also be necessary to gradu- ally let off on the throttle and steer to the out- side of the turn to avoid tipping over. Remember: Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.

Lean towards

inside of turn. Support your

weight on the

outer footboard

CLIMBING UPHILL

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

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 for- ward over the handlebars.

POTENTIAL HAZARD

Operating on excessively steep hills.

WHAT CAN HAPPEN

The vehicle can overturn more easily on

extremely steep hills than on level sur-

faces or small hills.

HOW TO AVOID THE HAZARD

Never operate the ATV on hills too steep

for the ATV or for your abilities.

Practice on smaller hills before attempting

large hills.

If your ATV has stalled or stopped and you believe you can continue up the hill, restart carefully to make sure you do not lift the front wheels which could cause you to lose control. If you are unable to continue up the hill, dismount the ATV on the uphill side. Physically turn the ATV around and then descend the hill.

If you start to roll backwards, DO NOT use the rear brake to stop. The ATV could easily tip over backwards. Instead, dismount the ATV immediately on the uphill side.

POTENTIAL HAZARD

Stalling, rolling backwards or improperly

dismounting while climbing a hill.

RIDING DOWNHILL

When riding your ATV downhill, shift your weight as far to the rear and uphill side of the ATV as possible. Move back on the seat and sit with your arms straight. Improper braking may cause a loss of traction. Use caution while descending a hill with loose or slippery surfaces. Braking ability and traction may be adversely affected by these surfaces. Improper braking may also cause a loss of traction. Whenever possible, ride your ATV straight downhill. Avoid sharp angles which could allow the ATV to tip or roll over. Carefully choose your path and ride no faster than you will be able to react to obstacles which may appear.

POTENTIAL HAZARD

Going down a hill improperly.

WHAT CAN HAPPEN

Could cause loss of control or cause the

ATV to overturn.

HOW TO AVOID THE HAZARD

Always follow proper procedures for

going down hills as described in this

Owners Manual. Note: a special tech-

nique is required when braking as you go

down a hill.

Always check the terrain carefully before

you start down any hill.

Shift your weight backward.

Never go down a hill at high speed.

Avoid going down a hill at an angle that

would cause the vehicle to lean sharply to

one side. Go straight down the hill where

possible.

CROSSING A SLOPE

Traversing a sloping surface on your ATV requires you to properly position your weight to maintain proper balance. Be sure that you have learned the basic riding skills on flat ground before attempting to cross a sloping surface. Avoid slopes with slippery surfaces or rough terrain that may upset your balance.

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

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

POTENTIAL HAZARD

Improperly crossing hills or turning on

hills.

WHAT CAN HAPPEN

CROSSING THROUGH SHALLOW WATER

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

POTENTIAL HAZARD

Operating this ATV through deep or fast

flowing water.

WHAT CAN HAPPEN

Tires may float, causing loss of traction

and loss of control, which could lead to an

accident.

HOW TO AVOID THE HAZARD

Never operate this ATV in fast flowing

water or in water deeper than that speci-

fied in your Owners Manual.

qWARNING

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.

3FA-9-1C-2 4/15/0 10:50 PM Page 7-34

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

SLIDING AND SKIDDING

Care should be used when riding on loose or slippery surfaces since the ATV may slide. If unexpected and uncorrected, sliding could lead to an accident. To reduce the tendency for the front wheels to slide in loose or slippery conditions, posi- tioning 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.

3FA-9-1C-2 4/15/0 10:50 PM Page 7-38

7-39

With practice, over a period of time, skill at controlled sliding can be developed. The ter- rain should be chosen carefully before attempting such maneuvers, since both sta- bility 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.

POTENTIAL HAZARD

Skidding or sliding improperly.

WHAT CAN HAPPEN

You may lose control of this ATV. You

may also regain traction unexpectedly,

which may cause the ATV to overturn.

HOW TO AVOID THE HAZARD

Learn to safely control skidding or sliding

by practicing at low speeds and on level,

smooth terrain.

On extremely slippery surfaces, such as

ice, go slowly and be very cautious in

order to reduce the chance of skidding or

sliding out of control.

WHAT TO DO ...

8 If your ATV doesnt turn when you want it to: Bring the ATV to a stop and practice the turning maneuvers again. Be sure you are putting your weight on the footboard to the outside of the turn. Position your weight over the front wheels for better control. (See pages 7-22 ~ 7-23.)

8 If your ATV begins to tip while turning: Lean more into the turn to regain balance. If necessary, gradually let off the throttle and/or steer to the outside of the turn. (See pages 7-22 ~ 7-23.)

8 If your ATV starts to slide sideways: Steer in the direction of the slide if you have the room. Applying the brakes or accelerating is not recommended until you have corrected the slide. (See pages 7-38 ~ 7-39.)

8 If your ATV cant make it up a hill you are trying to climb: Turn the ATV around if you still have for- ward 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 pages 7-24 ~ 7-29.)

3FA-9-1C-2 4/15/0 10:50 PM Page 7-40

8 If your ATV is traversing a sloping surface: Be sure to ride with your weight posi- tioned 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 bal- ance. If you discover that the ATV is going to tip over, dismount on the uphill side. (See pages 7-32 ~ 7-33.)

8 If your ATV encounters shallow water: Ride slowly and carefully through slow moving water, watching for obstacles. Be sure to let water drain from the ATV and CHECK YOUR BRAKES FOR PROPER OPERATION when you come out of the water. Do not continue to ride your ATV until you have regained adequate braking ability.

Spark plug inspection

The spark plug is an important engine com- ponent and is easy to inspect. The condition of the spark plug can indicate the condition of the engine. For example, a very white center electrode porcelain color could indicate an intake air leak or carburetion problem for that cylinder. Do not attempt to diagnose such problems yourself. Instead, take the machine to a Yamaha deal- er. You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, you should replace the spark plug with one of the proper type.

e. Fill the engine with oil and install the oil filler bolt.

cC Be sure no foreign material enters the

Troubleshooting

Although Yamaha machines receive a rigid inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems can cause poor starting and loss of power. The troubleshooting chart describes a quick, easy procedure for making checks. If your machine requires any repair, take it to a Yamaha dealer.

The skilled technicians at a Yamaha dealer- ship have the tools, experience, and know- how to properly service your machine. Use only genuine Yamaha parts on your machine. Imitation parts may look like Yamaha parts, but they are often inferior. Consequently, they have a shorter service life and can lead to expensive repair bills.

8-37

POTENTIAL HAZARD

Checking the fuel system while smoking

or near an open flame.

WHAT CAN HAPPEN

Fuel can ignite or explode, causing severe

injury or property damage.

HOW TO AVOID THE HAZARD

tem. Make sure there are no open flames

or sparks in the area, including pilot lights

from water heaters or furnaces.

CLEANING AND STORAGE

A. CLEANING

Frequent, thorough cleaning of your machine will not only enhance its appearance but will improve its general performance and extend the useful life of many components.

1. Before cleaning the machine: a. Block off the end of the exhaust pipe

to prevent water entry. A plastic bag and strong rubber band may be used.

b. Make sure the spark plug and all filler caps are properly installed.

2. If the engine case is excessively greasy, apply degreaser with a paint brush. Do not apply degreaser to the chain, sprock- ets or wheel axles.

3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure to do the job.

cC Excessive water pressure may cause water

seepage and deterioration of wheel bear-

ings, brakes, transmission seals and electri-

cal devices. Many expensive repair bills

have resulted from improper high pressure

detergent applications such as those avail-

able in coin-operated car washers.

4. Once the majority of the dirt has been hosed off, wash all surfaces with warm water and mild, detergent-type soap. An old toothbrush or bottle brush is handy for hard-to-get-at places.

5. Rinse the machine off immediately with clean water and dry all surfaces with a chamois, clean towel or soft absorbent cloth.

6. Dry the chain and lubricate it to prevent rust.

9-1

3FA-9-1C-3 4/15/0 10:53 PM Page 9-2

7. Clean the seat with a vinyl upholstery cleaner to keep the cover pliable and glossy.

8. Automotive type wax may be applied to all painted and chrome plated surfaces. Avoid combination cleaner-waxes. Many contain abrasives which may mar the paint or protective finish. When finished, start the engine and let it idle for several minutes.

9-2

POTENTIAL HAZARD

Operation with wet brakes after washing.

WHAT CAN HAPPEN

Wet brakes may have reduced stopping

ability, increasing the chance of an acci-

dent.

HOW TO AVOID THE HAZARD

Test the brakes after washing. Apply the

brakes several times at slow speeds to let

friction dry out the linings.

EBU00525

B. STORAGE

Long term storage (60 days or more) of your machine will require some preventive proce- dures to guard against deterioration. After thoroughly cleaning the machine, prepare for storage as follows:

1. Fill the fuel tank with fresh fuel and add the specified amount of Yamaha Fuel Stabilizer and Conditioner or an equiva- lent product.

NOTE:

Use of fuel stabilizer and conditioner elimi- nates the need to drain the fuel system. Consult a Yamaha dealer if the fuel system needs to be drained instead.

2. Remove the spark plug, pour about one tablespoon of SAE 10W30 or 20W40

9-3

Specified amount: 1 oz of stabilizer to each gallon of fuel (or 7.5 cc of stabilizer to each liter of fuel)

motor oil in the spark plug hole and rein- stall the spark plug. Ground the spark plug wire and turn the engine over sever- al times to coat the cylinder wall with oil.

3. Clean the drive chain thoroughly and lubricate it. (See page 8-25.)

4. Lubricate all control cables. 5. Block up the frame to raise all wheels off

the ground. 6. Tie a plastic bag over the exhaust pipe

outlet to prevent moisture from entering. 7. If storing in a humid or salt-air atmos-

phere, coat all exposed metal surfaces with a light film of oil. Do not apply oil to any rubber parts or the seat cover.

8. Remove the battery and charge it. Store it in a dry place and recharge it once a month. Do not store the battery in an excessively warm or cold place (less than 0C (30F) or more than 30C (90F)).

NOTE:

Make any necessary repairs before storing the machine.
