

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 operating 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.

2-2



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. 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 range 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 described 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 unless 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.



Never maintain an ATV without proper knowledge. Contact an authorized ATV dealer to inform you on basic ATV maintenance. Certain maintenance can only be carried out by certified staff.

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 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

2-4

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

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 confirmed 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

2-5 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 instability 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 accessories. 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.


EWB00073

WARNING

Avoid Carbon Monoxide Poisoning

All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nausea, confusion, and eventually death.

Carbon Monoxide is a colorless, odorless, tasteless gas which may be present even if you do not see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in 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 partially 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.

EBU20922

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

UB1661E0.book Page 6 Thursday, May 12, 2016 2:47 PM 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 interfere with your ability to control the ATV. Examples include (but are not limited to) a heavy or bulky object attached to the handlebars which could make steering difficult, an accessory that limits your ability to move around on the seat, or one that limits your view.



Use extra caution when riding an ATV with accessories. The ATV may handle differently than it does without accessories.

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

WARNING! You could collide with another vehicle if operating in areas where you cannot easily be seen. Mount a caution flag on the ATV to make you more visible.

Watch carefully for other vehicles.

[EWB01552]

Do not ride in areas posted “no trespassing”.

Do not ride on private property without getting permission.

7-11


Select a large, flat, unpaved area to become familiar with your ATV. Make sure that this area is free of obstacles and other riders. You should practice control of the throttle, brakes, shifting procedures, and turning techniques in this area before trying more difficult terrain.

Shift to the park position 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. With the engine idling, shift the drive select lever into the low-range position or the high-range position. Apply the throttle slowly and smoothly.

The centrifugal clutch will engage and you will start to accelerate. 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.

ECB00252

NOTICE

Do not shift from low-range to high-range or vice versa without coming to a complete stop.

Damage to the engine or drive train may occur.

TURNING YOUR ATV

EWB01772

WARNING

Always follow proper procedures for turning as described in this Owner’s Manual. Practice turning at low speeds before attempting to turn at faster speeds. Do not turn at speeds too fast for your skills or the conditions. ATV could go out of control, causing a collision or overturn.

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

7-12


7

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.

may continue to go straight. If the ATV doesn’t turn, come to a stop and then practice the procedure again. If the riding surface is slippery or loose, it may help to position more of your weight over the front wheels by moving forward on the seat.

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

Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the ATV to tip. If the ATV begins to tip over to the outside while negotiating a turn, lean more to the inside. It may also be necessary to gradually let off on the throttle and steer to the outside of the turn to avoid tipping over.

Remember: Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.

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 unpaved area with no obstacles. If an incorrect technique is used, your ATV

CLIMBING UPHILL

EWB01672

WARNING

Climbing hills improperly can cause overturns or loss of control. Use proper riding techniques described in this Owner’s Manual.




Never operate the ATV on hills too steep for the ATV or for your abilities. The ATV can overturn more easily on extremely steep hills than on level surfaces or small hills.



Always check the terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces.



Shift your weight forward.



Never open the throttle suddenly. 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 possible. When crossing the side of a hill, shift your weight to the uphill side of the ATV.

7-14

7


7

Do not attempt to climb hills until you have mastered basic maneuvers on flat ground. Always check the terrain carefully before attempting any hill. In all cases avoid inclines with slippery or loose surfaces, or obstacles that might cause you to lose control.

To climb a hill, you need traction, momentum, and steady throttle. For more traction and control for climbing steeper and/or rougher slopes, select

“4WD” or 4WD-LOCK (“DIFF. LOCK”)

(YFM70KPSH). Travel fast enough to maintain momentum, but not so fast that you cannot react to changes in the terrain as you climb.

It is important when climbing a hill to make sure that your weight is transferred forward on the ATV.

This can be accomplished by leaning forward and, on steeper inclines, standing on the 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

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 shift to the park position. If you are in “4WD”, 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 shift to the park position and dismount the ATV immediately on the uphill side. Dismount on uphill side or to a side if pointed

UB1661E0.book Page 16 Thursday, May 12, 2016 2:47 PM 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.

[EWB01803]

RIDING DOWNHILL

EWB01622

WARNING

Going down a hill improperly could cause overturns or loss of control. Always follow proper procedures for going down hills as described in this Owner’s Manual.

7-16



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. 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, select the low-range position and change to “4WD” before beginning to descend the hill.

7


7

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.

7-17

CROSSING A SLOPE

EWB01633

WARNING

Improperly crossing hills or turning on hills could cause loss of control or cause the ATV to overturn.



Always follow proper procedures as described 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.

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

EWB01642

WARNING

Operating this vehicle through deep or fastflowing water can lead to loss of control or an overturn. To reduce your risk of drowning or other injuries, use care when crossing through water. Never operate this ATV water deeper than the depth specified in your Owner’s Manual, as tires may float, increasing the risk of an overturn.

7


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.

RIDING OVER ROUGH TERRAIN

EWB01652

WARNING

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

Riding over rough terrain should be done with caution. Look out for obstacles which could cause damage to the ATV or could lead to an upset or

accident. Be sure to keep your feet firmly mounted on the footboards at all times. Avoid jumping the

ATV as loss of control and damage to the ATV may result.

SLIDING AND SKIDDING

EWB01663

WARNING

Skidding or sliding improperly may cause you to lose control of this ATV. You may also regain traction unexpectedly, which may cause the

ATV to overturn.



Learn to safely control skidding or sliding by practicing at low speeds and on level, smooth terrain.



On extremely slippery surfaces, such as ice, go slowly and be very cautious in order to reduce the chance of skidding or sliding out of control.

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

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

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

7-21


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

WHAT TO DO IF...

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

7-22

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

7-13.)

7


7



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.)

EWB02721

WARNING

Improper maintenance can result in loss of braking ability. Observe these precautions:

8-44



Insufficient brake fluid may allow air to enter the brake system, reducing braking performance.



Clean the filler cap before removing. Use only DOT 4 brake fluid from a sealed container.



Use only the specified brake fluid; otherwise, the rubber seals may deteriorate, causing leakage.



Refill with the same type of brake fluid. Adding a brake fluid other than DOT 4 may result in a harmful chemical reaction.



Be careful that water does not enter the brake fluid reservoir when refilling. Water will significantly lower the boiling point of the fluid and may result in vapor lock.

ECB01161

NOTICE

Brake fluid may damage painted surfaces or plastic parts. Always clean up spilled fluid immediately.

As the brake pads wear, it is normal for the brake fluid level to gradually go down. A low brake fluid level may indicate worn brake pads and/or brake system leakage; therefore, be sure to check the

UB1661E0.book Page 45 Thursday, May 12, 2016 2:47 PM brake pads for wear and the brake system for leakage. If the brake fluid level goes down suddenly, have a Yamaha dealer check the cause before further riding.

Troubleshooting

Although Yamaha ATVs receive a thorough inspection before shipment from the factory, trouble may occur during operation. Any problem in the fuel, compression, or ignition systems, for example, can cause poor starting and loss of power.

The following troubleshooting charts represent quick and easy procedures for checking these vital systems yourself. However, should your ATV require any repair, take it to a Yamaha dealer, whose skilled technicians have the necessary tools, experience, and know-how to service the

ATV properly.

Use only genuine Yamaha replacement parts. Imitation parts may look like Yamaha parts, but they are often inferior, have a shorter service life and can lead to expensive repair bills.

EWB02281

WARNING

Do not smoke when checking the fuel system.

Fuel can ignite or explode, causing severe injury or property damage. Make sure there are no open flames or sparks in the area, including pilot lights from water heaters or furnaces.

Cleaning

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

1. Before cleaning the ATV: 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 wheel axles.

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

WARNING! Wet brakes may have reduced stopping ability, increasing the chance of an accident. Test the brakes after washing. Apply the brakes several times at slow speeds to let friction dry out the linings.

[EWB02312]

NOTICE:

Excessive water pressure may cause water seepage

CLEANING AND STORAGE

and deterioration of wheel bearings, brakes, transmission seals and electrical devices. Many expensive repair bills have resulted from improper high-pressure detergent applications such as those available in coin-operated car washers.

[ECB00712]

4. Once most 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-reach places.

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

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

7. 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 cleaning, start the engine and let it idle for several minutes.

EBU27262

Storage

Short-term

Always store your ATV in a cool, dry place and, if necessary, protect it against dust with a porous cover.

NOTICE:

Storing the ATV in a poorly ventilated room or covering it with a tarp while it is still wet, will allow water and humidity to seep in and cause rust. To prevent corrosion, avoid damp cellars, stables (because of the presence of ammonia) and areas where strong chemicals are stored.

[ECB00722]

Long-term

Before storing your ATV for several months:

1. Follow all the instructions in the “Cleaning” section of this chapter.

2. Fill up the fuel tank and add fuel stabilizer (if available) to prevent the fuel from deteriorating.

Specified amount:

7.5 ml of stabilizer to each liter of fuel (or 1 oz of stabilizer to each gallon of fuel)

3. Perform the following steps to protect the cylinder, piston rings, etc. from corrosion.

a. Remove the spark plug cap and spark plug.

b. Pour a teaspoonful of engine oil into the spark plug bore.

c. Install the spark plug cap onto the spark plug, and then place the spark plug on the cylinder head so that the electrodes are grounded. (This will limit sparking during the next step.) d. Turn the engine over several times with the starter. (This will coat the cylinder wall with oil.) e. Remove the spark plug cap from the spark plug, and then install the spark plug and the spark plug cap.

4. Lubricate all control cables and the pivoting points of all levers and pedals.

5. Check and, if necessary, correct the tire air pressure, and then block up the ATV so that all of its wheels are off the ground. Alternatively, turn the wheels a little every month in order to prevent the tires from becoming degraded in one spot.

For Europe only

The figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required.

Factors that influence the actual level of exposure of work-force include the characteristics of the work room, the other sources of noise, etc. i.e. the number of machines and other adjacent processes, and the length of time for which an operator is exposed to the noise. Also the permissible exposure level can vary from country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk.
