Introduction

Congratulations on choosing your Honda ATV.

When you own a Honda, you’re part of a worldwide family of satisfied customers − people who appreciate Honda’s reputation for building quality into every product.

Your Honda was designed as a recreational ATV for off-road use by one rider only.

Before riding, take time to get acquainted with your ATV and how it works. To protect your investment, we urge you to take responsibility for keeping your ATV well maintained. Scheduled service is a must, of course. But it’s just as important to observe the break-in guidelines, and perform all pre-ride and other periodic checks detailed in this manual.

We also recommend that you read this owner’s manual before you ride.

It’s full of facts, instructions, safety information, and helpful tips. To make it easy to use, the manual contains a detailed list of topics at the beginning of each section and an index at the back of the book.

As you read this manual, you will find information that is preceded by a symbol. This information is intended to help you avoid damage to your Honda, other property, or the environment.

Read the Warranties Booklet (page 225 ) thoroughly so you understand the coverages that protect your new Honda and are aware of your rights and responsibilities.

Whenever you ride, tread lightly. By staying on established trails and riding only in approved areas, you help protect the environment and keep off-road riding areas open for the future.

Important Safety Information

Your ATV can provide many years of service and pleasure if you take responsibility for your own safety and understand the challenges you can meet while riding.

There is much that you can do to protect yourself when you ride. You’ll find many helpful recommendations throughout this manual. The following are a few that we consider to be most important.

Follow the Age Recommendation

The minimum recommended age for this ATV model is 16. Children under age 16 should never operate this vehicle. Refer to the age warnings provided in this manual and on the ATV.

Always Wear a Helmet

It’s a proven fact: helmets significantly reduce the number and severity of head injuries. So always wear an approved motorcycle helmet. We also recommend that you wear eye protection, sturdy boots, gloves, and other protective gear (page 38 ).

Never Carry a Passenger

Your ATV is designed for one person only. There are no handholds, footrests, or seat for a second person, so never carry a passenger. A passenger could interfere with your ability to move around to maintain your balance and control of the ATV.

ATV Safety

１１／０５／０９１３：０２：２６３１ＨＰ４６５０００１２


Ride Off-road Only

Your ATV is designed and manufactured for off-road use only. The tires are not made for pavement, and the ATV does not have turn signals and other features required for use on public roads. If you need to cross a paved or public road, get off and walk your ATV across.

Take Time to Learn & Practice

Even if you have ridden other ATVs, take time to become familiar with how this ATV works and handles. Practice in a safe area until you build your skills and get accustomed to the ATV’s size and weight.

Because many crashes involve inexperienced or untrained riders, we urge all riders to take a ATV operator course approved by the ATV

Safety Institute (ASI). See page 40 .

Contact an authorized ATV dealer or call 1-800-887-2887 to find out about the training courses nearest you.

Be Alert for Off-road Hazards

The terrain can present a variety of challenges when you ride off-road.

Continually ‘‘read’’ the terrain for unexpected turns, drop-offs, rocks, ruts, and other hazards. Always keep your speed low enough to allow time to see and react to hazards.

ATV Safety

１１／０５／０９１３：０２：３２３１ＨＰ４６５０００１３


Ride within Your Limits

Pushing limits is another major cause of ATV crashes. Never ride beyond your personal abilities or faster than conditions warrant.

Remember that alcohol, drugs, fatigue, and inattention can significantly reduce your ability to make good judgments and ride safely.

Don’t Drink and Ride

Alcohol and riding don’t mix. Even one drink can reduce your ability to respond to changing conditions, and your reaction time gets worse with every additional drink. So don’t drink and ride, and don’t let your friends drink and ride either.

Keep Your Honda in Safe Condition

It’s important to keep your ATV properly maintained and in safe riding condition. Having a breakdown can be difficult, especially if you are stranded off-road far from your base. To help avoid problems, inspect your ATV before every ride and perform all recommended maintenance.

１１／０５／０９１３：０２：３６３１ＨＰ４６５０００１４

Safety Labels

Your ATV comes with a hang tag and several labels containing important safety information. Anyone who rides the vehicle should read and understand this information before riding.

The labels should be considered permanent parts of the vehicle. If a label comes off or becomes hard to read, contact your dealer for replacements.

PS (Electric Power Steering) ( TRX420FPM only)

This ATV is equipped with an electronically controlled, electric-powerassisted steering system.

While the engine is running, the PS (Electric Power Steering) system provides power from the electric motor, which helps you to turn the

ATV’s handlebar more easily.

The PS system on this ATV utilizes an overheat protection feature to prevent damage to system components. In certain extended, repetitive high-load situations, the system will reduce or even disable power steering assist. The steering will perform as a normal non-PS system during this brief period. After cooling down, it will then return to normal PS operation.

The PS indicator should light when the ignition switch is turned ON

( ) and remain on until the engine is started.

The PS indicator also lights when there is any abnormality in the PS system. If this occurs, the electric power assist for turning will not be available, but the manual steering system will perform as usual.

If the PS indicator lights at any time while riding, reduce speed and take your ATV to your dealer as soon as possible. Continuing to ride with a

PS system problem can cause system damage.

Do not modify your Electric Power Steering system. In case of a malfunction, take your ATV to your dealer.

Are You Ready to Ride?

Before you ride your ATV for the first time, we urge you to:

Read this owner’s manual and the labels on your ATV carefully.

Make sure you understand all the safety messages.

Know how to operate all the controls.

Before each ride, be sure:

You feel well and are in good physical and mental condition.

You are wearing an approved motorcycle helmet (with chin strap tightened securely), eye protection, and other protective clothing.

You don’t have any alcohol or drugs in your system.

Protective Apparel

For your safety, we strongly recommend that you always wear an approved motorcycle helmet, eye protection, boots, gloves, long pants, and a long-sleeved shirt or jacket whenever you ride.

Although complete protection is not possible, wearing proper gear can reduce the chance of injury when you ride.

Following are suggestions to help you choose the proper gear.

Helmet and Eye Protection

Your helmet is your most important piece of riding gear because it offers the best protection against head injuries. A helmet should fit your head comfortably and securely.

38

Before Riding

１１／０５／０９１３：０６：５５３１ＨＰ４６５０００４８


An open-face helmet offers some protection, but a full-face helmet offers more. Regardless of the style, look for a DOT (Department of

Transportation) sticker on any helmet you buy. Always wear a face shield or goggles to protect your eyes and help your vision.

Operating this ATV without wearing an approved motorcycle helmet, eye protection, and protective clothing could increase your chances of severe injury or death in the event of an accident.

Always wear an approved motorcycle helmet that fits properly and wear eye protection

(goggles or face shield), gloves, boots, long-sleeved shirt or jacket and long pants.

Additional Riding Gear

In addition to a helmet and eye protection, we also recommend:

Sturdy off-road motorcycle boots to help protect your feet, ankles, and lower legs.

Off-road motorcycle gloves to help protect your hands.

Riding pants with knee and hip pads, a riding jersey with padded elbows, and a chest/shoulder protector.

Load Limits & Guidelines

Your Honda was designed as a rider-only ATV. It was not designed to carry a passenger. It can carry cargo on the cargo racks, however, carrying cargo anywhere else or carrying a passenger could interfere with your balance and control of the ATV.

In addition, exceeding the weight limits or carrying an unbalanced load can seriously affect your ATV’s handling, braking and stability. Adding accessories or making modifications that change this ATV’s design and performance can also make it unsafe. Also, the weight of any accessories will reduce the maximum load the ATV can carry.

More specific information on load limits, accessories, and modifications follows.

Loading

How much weight you put on your ATV, and how you load it, are important to your safety. If you decide to carry cargo, you should be aware of the following information.

Overloading, improper loading, or carrying a passenger can cause a crash and you can be seriously hurt or killed.

Follow all load limits and other loading guidelines in this manual.

Before Riding

１１／０５／０９１３：０８：１９３１ＨＰ４６５０００５８


Loading Guidelines

Carrying cargo or pulling a trailer will affect how your ATV handles and greatly reduce its ability in accelerating, braking and making turns and other maneuvers.

Be sure to observe the weight limits and follow these guidelines:

Check that the tires are properly inflated.

Do not place cargo anywhere on the ATV other than on the front and rear racks. Otherwise, operating stability may be adversely affected.

Never ride with a passenger on the front or rear cargo racks. The

ATV is not designed to carry a passenger.

Use the trailer hitch to tow another vehicle or trailer. Do not tow by tying a rope or cable to the rear rack.

Load cargo on the rear rack as far forward as possible. Make sure cargo on the front rack does not interfere with handlebar movement.

Do not allow cargo to extend beyond the edges of either the front or rear racks.

Make sure all cargo is secured before riding.

Balance cargo weight evenly on both sides.

Never exceed the maximum weight limit.

When towing a trailer, take care to maintain balance and stability.

Distribute cargo between the front and rear of the trailer to obtain the recommended tongue weight.

Allow extra room for starting, stopping and turning whenever you carry cargo or pull a trailer.

Avoid riding on steep slopes when carrying cargo or pulling a trailer.

Never cross a slope when towing a trailer.

Safe Riding Precautions

Before riding your ATV for the first time, please review the section beginning on page 1, and the Bef ore Riding

ATV Saf ety section beginning on page 37 .

Even if you have ridden other ATVs, take time to become familiar with how this ATV works and handles. Practice in a safe area until you build your skills and get accustomed to the ATV’s size and weight.

Off-road Use Only

Your ATV and its tires are designed and manufactured for off-road use only, not for pavement. Riding on pavement can affect handling and control. You should not ride your ATV on pavement.

Operating this ATV on paved surfaces may seriously affect handling and control of the ATV, and may cause the vehicle to go out of control.

Never operate the ATV on any paved surfaces, including sidewalks, driveways, parking lots and streets.

When riding off-road, also remember to always obey local off-road riding laws and regulations. Obtain permission to ride on private property. Avoid posted areas and obey ‘‘no trespassing’’ signs.


55

１１／０５／０９１３：０９：０７３１ＨＰ４６５０００６５


You should never ride your ATV on public streets, roads or highways, even if they are not paved. Drivers of street vehicles may have difficulty seeing and avoiding you, which could lead to a collision. In many states it is illegal to operate ATVs on public streets, roads and highways.

Operating this ATV on public streets, roads or highways could cause you to collide with another vehicle.

Never operate this ATV on any public street, road or highway, even a dirt or gravel one.

Keep Hands and Feet on Controls

Always keep both hands on the handlebars and both feet on the footpegs when riding your ATV. This is important to maintain your balance and to control the vehicle. Removing even one hand from the handlebars or one foot from the footpegs can reduce your ability to control the ATV or could cause you to lose your balance and fall off the ATV.

Removing hands from handlebars or feet from footpegs during operation can reduce your ability to control the ATV or could cause you to lose your balance and fall off of the ATV.

Always keep both hands on the handlebars and both feet on the footpegs of your ATV during operation.

56


１１／０５／０９１３：０９：１１３１ＨＰ４６５０００６６


Control Speed

Riding at excessive speed increases the chance of a crash. In choosing a proper speed, you need to consider the capability of your vehicle, the terrain, visibility and other operating conditions, plus your own skills and experience.

Operating this ATV at excessive speeds increases your chances of losing control of the

ATV, which can result in an accident.

Always go at a speed that is proper for your vehicle, the terrain, visibility and other operating conditions, and your experience.


57

１１／０５／０９１３：０９：１５３１ＨＰ４６５０００６７


Use Care on Unfamiliar or Rough Terrain

Before riding in a new area, always check the terrain thoroughly. Don’t ride fast on unfamiliar terrain or when visibility is limited. (It’s sometimes difficult to see obstructions like hidden rocks, bumps, or holes in time to react.)

Failure to use extra care when operating this

ATV on unfamiliar terrain could result in the ATV overturning or going out of control.

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

ATV.

58


１１／０５／０９１３：０９：２１３１ＨＰ４６５０００６８


Never ride past the limit of visibility. Maintain a safe distance between your ATV and other off-road vehicles. Always exercise caution, and use extra care on rough, slippery and loose terrain.

Failure to use extra care when operating on excessively rough, slippery or loose terrain could cause loss of traction or vehicle control, which could result in an accident, including an overturn.

Do not 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.

Do Not Perform Stunts

You should always operate your ATV in a safe and reasonable manner.

When riding, always keep all four wheels on the ground.

Attempting wheelies, jumps, and other stunts increases the chance of an accident, including an overturn.

Never attempt stunts, such as wheelies or jumps. Don’t try to show off.


59

１１／０５／０９１３：０９：３１３１ＨＰ４６５０００６９

Starting & Stopping the Engine

Always follow the proper starting procedure described below.

For your safety, avoid starting or operating the engine in an enclosed area such as a garage. Your ATV’s exhaust contains poisonous carbon monoxide gas which can collect rapidly in an enclosed area and cause illness or death.

63

１１／０５／０９１３：０９：５６３１ＨＰ４６５０００７３


How to Stop the Engine

Normal Engine Stop

To stop the engine, make sure the transmission is in neutral by checking that the neutral indicator light is on, then turn the ignition switch OFF

( ).

The engine stop switch should normally remain in the RUN ( ) position even when the engine is OFF.

If your ATV is stopped with the engine stop switch OFF ( ) and the ignition switch ON ( ), the battery will discharge.

Emergency Engine Stop

To stop the engine in an emergency, use the engine stop switch. To operate, slide the switch to either OFF ( ) position.

64


１１／０５／０９１３：１０：０４３１ＨＰ４６５０００７４

Shifting Gears

UPSHIFTING SEQUENCE

DOWNSHIFTING SEQUENCE

Your ATV has five forward gears: 1, 2, 3, 4, and 5.

The shift lever is located near the left footpeg. One full stroke of the shift lever shifts the transmission to the next higher or lower gear in the shifting sequence. The shift lever automatically returns to the horizontal position when released.

To upshift to a higher gear, put the toe of your boot under the shift lever and raise it one full stroke. To downshift, step on the shift lever and depress it one full stroke.

To select reverse, use the reverse selector knob (page 67 ).

After starting the engine and letting it warm up, follow these procedures:

1.

With the transmission in neutral, release the parking brake, but continue squeezing the rear brake lever.

(cont’d)


65

１１／０５／０９１３：１０：１４３１ＨＰ４６５０００７５

Shifting Gears

2.

With the throttle closed, raise the shift lever one full stroke to shift into 1st (first) gear.

3.

Release the rear brake lever and increase engine speed by gradually opening the throttle.

4.

When speed increases, release the throttle and shift to 2nd gear by raising the shift lever one full stroke.

5.

Repeat this sequence to progressively upshift to 3rd, 4th and 5th (top) gear.

6.

To downshift, reverse this sequence. Remember to close the throttle each time you shift to the next lower gear.

Learning when to shift gears comes with experience. Keep the following tips in mind:

As a general rule, shift while moving in a straight line.

Close the throttle completely before shifting. Improper shifting may damage the engine, transmission, and drivetrain.

Upshift to a higher gear or reduce throttle before engine rpm (speed) gets too high. Learn the relationship between engine sound and the normal shifting points.

Downshift to a lower gear before you feel the engine laboring

(lugging) at low rpm.

Avoid downshifting to help slow your ATV when engine rpm is high.

Downshifting when engine speed is near its allowable maximum may over-rev the engine and possibly cause damage.

To prevent transmission damage, do not coast or tow the ATV for long distances with the engine off.

Recommended Shift Points

Ride in the highest gear that lets the engine run and accelerate smoothly.

This will give you good fuel economy and effective emissions control.

66


１１／０５／０９１３：１０：２１３１ＨＰ４６５０００７６

Riding in Reverse

If you need to ride in reverse, make sure the area behind you is clear and only operate the ATV at low speed.

Improperly operating in reverse could cause you to hit an obstacle or person behind you, resulting in serious injury.

Make sure there are no obstacles or people behind you before selecting reverse gear. When it is safe to proceed, go slowly.

1.

Bring the vehicle to a complete stop, then make sure the transmission is in neutral.

2.

Be sure there are no obstacles or people in the way.

suddenly or make abrupt turns.

To stop, close the throttle and gradually apply both the front and rear brakes. Do not abruptly apply the rear brake by itself.

To shift out of reverse and into neutral, raise the shift lever one stroke.

Applying only the rear brake abruptly when operating in reverse gear could cause the front wheels to lift off the ground and the ATV could overturn backwards.

Carefully apply both the front and rear brakes when stopping in reverse gear.

68


１１／０５／０９１３：１０：３３３１ＨＰ４６５０００７８

Braking

Your ATV is equipped with disc brakes on both front wheels which are hydraulically activated by operating the right brake lever. A single drum brake on the rear axle housing is mechanically activated by depressing the brake pedal or operating the left brake lever.

Except TRX420TM:

Although the front and rear brakes have separate controls, all four wheels are interconnected when your ATV is in the 4WD mode. So operating any brake control in the 4WD mode will cause braking at both the front and rear wheels.

As a general rule, the front braking system provides about 70 percent of total stopping power.

For full braking effectiveness, use both the pedal and lever simultaneously. Using both braking systems will stop your ATV faster with greater stability.

To slow or stop, apply the brake lever and brake pedal smoothly, while downshifting to match your speed.

Gradually increase braking as you feel the brakes slowing your speed.

The increase in engine compression from downshifting will help slow your ATV.

Applying the brakes too hard may cause the wheels to lock and slide, reducing control of your ATV. If this happens, release the brake controls, steer straight ahead until you regain control, then reapply the brakes more gently.

When possible, reduce your speed or complete braking before entering a turn. Avoid braking or closing the throttle quickly while turning. Either action may cause one or more wheels to slip and reduce your control of your ATV.


69

１１／０５／０９１３：１０：３８３１ＨＰ４６５０００７９

Braking

Your ability to brake in a turn and to brake hard in an emergency situation are important riding skills.

When descending a long, steep grade, use engine compression braking by downshifting, with intermittent use of both brakes. Continuous brake application can overheat the brakes and reduce their effectiveness.

Riding with your foot resting on the brake pedal or your hands on the brake levers may overheat the brakes, reducing effectiveness.

For information on how to apply the brakes in various riding situations, see the following section, Riding Your ATV .

Making Turns

Learn how to turn your ATV properly. Practice the techniques outlined in this section on level ground and at low speeds until you are confident in making turns.

Turning improperly can make the ATV go out of control, causing a collision or overturn.

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 excessive speeds.


71

１１／０５／０９１３：１０：４９３１ＨＰ４６５０００８１

Riding Your ATV

Lean your body to the inside of a turn and forward.

To make a turn on level ground: Steer the handlebar and lean your body toward the inside of the turn. Leaning helps balance the vehicle, and it feels more comfortable. Leaning into a turn is an important technique to master in riding an ATV.

To make a sharp turn at low speed: It helps to shift your body slightly forward on the seat, and lean inside, as you steer the handlebar. Shifting weight forward allows the rear wheels to turn easier, and it also improves front-wheel steering.

To make a turn from a full stop: Apply the throttle gradually when you turn and start up at the same time. Remember to shift your body forward to make sharp low-speed turns and whenever you turn while accelerating from a full stop.

72


１１／０５／０９１３：１０：５４３１ＨＰ４６５０００８２

Riding Your ATV

Skidding or Sliding

The terrain surface can be a major factor affecting turns. Skidding during a turn is more likely to occur on slippery surfaces, such as snow, ice, mud and loose gravel. If you skid on ice, you may lose all directional control. To avoid skidding on slippery terrain, keep your speed low and ride with caution.

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 by practicing at low speeds and on level, smooth terrain.

If your ATV skids sideways during a turn, steer in the direction of the skid. Avoid hard braking or accelerating until you have regained directional control.


73

１１／０５／０９１３：１１：００３１ＨＰ４６５０００８３

Riding Your ATV

Riding Up Hills

The ATV’s ability to safely climb hills largely depends on the rider’s skill and judgment. Begin by practicing on smooth, gentle slopes. As you gain experience, you’ll learn the hazards and your own limitations.

You may then proceed to ride on more difficult terrain. However, you must be able to decide which hills or hazards might cause the ATV to overturn. Avoid excessively steep hills.

Operating on excessively steep hills can cause the vehicle to overturn more easily than operating on level surfaces or small hills.

Never operate the ATV on hills too steep for the

ATV or for your abilities.

When climbing hills, you must shift weight toward the front wheels to help keep them on the ground. To do this, shift your body slightly forward on the seat and lean forward. For greater weight shift, move your body farther forward and lean forward.

Climbing hills improperly could cause loss of control or cause the ATV to overturn.

Always follow proper procedures for climbing hills as described in this owner’s manual.

74


１１／０５／０９１３：１１：０６３１ＨＰ４６５０００８４

Riding Your ATV

Shift weight forward when climbing hills.

Always check the terrain carefully before you start up any hill.

Never climb hills with excessively slippery or loose surfaces.

To climb a hill, take a running start in an appropriate gear and speed for the conditions. Maintain a steady speed as you ascend the hill.

Never open the throttle suddenly or make sudden gear changes. The

ATV could flip over backward.

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.


75

１１／０５／０９１３：１１：１５３１ＨＰ４６５０００８５

Riding Your ATV

Stalling the ATV and/or Rolling Backwards:

If you incorrectly estimate climbing capability or terrain conditions, the

ATV may not have enough power or traction to continue uphill. If this happens, the ATV can stall and/or roll backwards.

Stalling, rolling backwards or improperly dismounting while climbing a hill could result in the ATV overturning.

Always follow proper procedures for climbing a hill as described in this owner’s manual.

What to do if the ATV stalls or rolls backwards when climbing a hill:

If you are about to lose all forward speed:

1.

Using the front and rear brakes together, bring the ATV to a stop with the vehicle pointed straight uphill.

2.

3.

Get off the ATV while you continue holding the brakes.

Shift into neutral, set the parking brake and turn the engine off.

4.

Then assess the situation.

If the ATV starts rolling backwards before you begin braking:

1.

2.

Keep your weight uphill.

Carefully apply the front brakes first, then carefully apply the rear brake. Do not apply either brake abruptly if you are rolling backwards, or the vehicle may overturn.

If the ATV continues sliding backwards:

After you’ve applied the brakes, get off and away from the vehicle.

Except TRX420TM:

Remember that operating any brake control in the 4WD mode will cause braking at both the front and rear wheels.

76


１１／０５／０９１３：１１：２３３１ＨＰ４６５０００８６

Riding Your ATV

What to do after the ATV has stalled or rolled backwards:

If the hill is too steep or too slippery, or if you have any doubt whether you can safely walk the ATV back down the hill, leave the vehicle where it is and get help. If possible, block the wheels so the vehicle doesn’t roll backwards.

If the hill is not too steep and you have good footing, you may be able to walk the ATV back down the hill. Make sure your intended path is clear in case you lose control of the ATV.

Be sure your legs are clear of the wheels.

Body position for backing down a hill.

1.

Stand with your body facing downhill, beside the vehicle so you can reach the rear brake lever with your right hand.

2.

Be sure your legs are clear of the wheels.

Check your footing.

3.

Slowly and carefully back the ATV down the hill using the rear brake lever to control speed.

4.

If you lose control of the ATV, for your safety, get away from the vehicle.


77

１１／０５／０９１３：１１：３０３１ＨＰ４６５０００８７

Riding Your ATV

Riding Down Hills

It’s usually advisable to descend hills with the ATV pointed straight downhill. Avoid angles that would cause the vehicle to lean sharply to one side.

Going down a hill improperly could cause loss of control or cause the ATV to overturn.

Always follow proper procedures for going down hills as described in this owner’s manual.

On downhills, shift your weight back.

As you approach a downhill, stop and survey the terrain below. Never ride past the limit of your visibility. Never go down a hill at high speed.

78


１１／０５／０９１３：１１：３６３１ＨＰ４６５０００８８

Riding Your ATV

When you’ve selected a safe downhill path, shift into a lower gear, shift your weight back with your arms extended and braced against the handlebar, then go down slowly with the throttle closed.

Use mainly the rear brake to control speed. Avoid using either the front brake or rear brake hard or abruptly when riding down hills.

Except TRX420TM:

Remember that operating any brake control in the 4WD mode will cause braking at both the front and rear wheels.

Remember, braking effectiveness is reduced on any hill with a loose surface.

Crossing or Turning on Hills or Slopes

Riding on hills or slopes is different from riding on level terrain. Be careful when riding on any hill. Make sure that you practice on gentle, smooth slopes before attempting to ride on steeper or more difficult terrain.

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

Always follow proper procedures for crossing or turning on slopes as described in this owner’s manual. Avoid crossing steep hills if possible.


79

１１／０５／０９１３：１１：４４３１ＨＰ４６５０００８９

Riding Your ATV

Crossing Hills or Slopes

To maintain balance and stability when riding across a slope, you need to shift weight toward the uphill side of the vehicle. To do this, move your body off the center of the seat and lean toward the uphill side.

On a slippery or loose surface, you may also need to steer slightly uphill to maintain a straight course across the slope.

Avoid crossing hills that are excessively steep, slippery or rough.

Shift weight uphill when crossing slopes.

Making Turns on Slopes

Compared to riding on level ground, you may need to shift more weight and lean more when making turns on slopes.

Do not make turns on any slopes until you have first mastered the techniques for making turns on level terrain.

80


１１／０５／０９１３：１１：４９３１ＨＰ４６５０００９０

Riding Your ATV

Riding Over Obstacles

Before operating in a new area, check for obstacles. Watch out for bumps, rain ruts, potholes and other obstacles in the terrain. When you approach any obstacle, reduce your speed and be prepared to stop.

Never try to ride over large obstacles, such as large rocks or fallen logs.

Improperly operating over obstacles could cause loss of control or a collision and could cause the ATV to overturn.

When you go over obstacles, always follow proper procedures as described in this owner’s manual.


81

１１／０５／０９１３：１１：５８３１ＨＰ４６５０００９１

Riding Your ATV

Riding Through Water

Your ATV is designed to travel through water up to approximately

10 inches (254 mm) deep. Before crossing a stream, make sure the water is not too deep or flowing too fast.

The ATV tires have some ability to float.

Operating this ATV through deep or fast-flowing water may cause a loss of traction and loss of control, which could lead to an accident.

Never operate this ATV in fast-flowing water or in water deeper than that specified in this owner’s manual.

1.

Choose a path where both banks have gradual slopes.

2.

3.

Proceed through the water at a slow, steady speed.

Watch out for submerged obstacles and slippery rocks.

4.

5.

Avoid getting the spark plug or air cleaner wet, as this would cause the engine to stop.

After leaving the water, always test both the front and rear brakes.

Riding through water can make the brakes less effective than normal, and may reduce stopping ability.

If necessary, apply the brakes repeatedly until they dry out and operate normally.

If the brakes don’t regain effectiveness, stop your ATV and follow the procedures on page 153 .

82


１１／０５／０９１３：１２：０９３１ＨＰ４６５０００９２

Fuel Recommendation

type pump octane number unleaded

86 (or higher)

Use only unleaded fuel in your Honda. If you ride your Honda in a country where leaded fuel might be available, take precautions to use only unleaded fuel.

Your engine is designed to use any unleaded gasoline that has a pump octane number of 86 or higher. Gasoline pumps at service stations normally display the pump octane number. For information on the use of oxygenated fuels, see page 220 .

Use of lower octane gasoline can cause persistent ‘‘pinging’’ or ‘‘spark knock’’ (a loud rapping noise) which, if severe, can lead to engine damage. Light pinging experienced while operating under a heavy load, such as climbing a hill, is no cause for concern.

If pinging or spark knock occurs at a steady engine speed under normal load, change brands of gasoline. If pinging or spark knock persists, consult your dealer.

Never use stale or contaminated gasoline or an oil/gasoline mixture.

Avoid getting dirt, dust, or water in the fuel tank.

Engine Oil & Filter

Engine oil quality is a major factor that affects both the performance and the service life of the engine.

Using the proper oil (page 106 ) and filter, and regularly checking, adding, and changing oil will help extend your engine’s life. Even the best oil wears out. Changing oil helps get rid of dirt and deposits in the engine. Operating the engine with old or dirty oil can damage your engine. Running the engine with insufficient oil can cause serious damage to the engine and transmission.

Change the engine oil as specified in the maintenance schedule on page 92 . When running in very dusty conditions, oil changes should be performed more frequently than specified in the maintenance schedule.

Changing Engine Oil & Filter


Your ATV’s oil filter has very specific performance requirements. Use a new Honda Genuine oil filter specified for your model or a filter of equal quality.

Using the wrong oil f ilter may result in leaks or engine damage.

This procedure requires mechanical skill and professional tools such as a torque wrench as well as a means for disposing of the drained fluid

(page 184 ). If you do not have the skills or the tools, see your dealer.

Change the oil with the engine warm to assure complete and rapid draining.

Drain the Engine Oil:

Coolant

Your ATV’s liquid cooling system dissipates engine heat through the coolant jacket that surrounds the cylinder and cylinder head.

Maintaining the coolant will allow the cooling system to work properly and prevent freezing, overheating, and corrosion.

Coolant Recommendation

Use Pro Honda HP coolant or an equivalent high quality ethylene glycol antifreeze containing corrosion protection inhibitors specifically recommended for use in aluminum engines. Check the antifreeze container label.

Use only distilled water as a part of the coolant solution. Water that is high in mineral content or salt may be harmful to the aluminum engine.

Using coolant with silicate inhibitors may cause premature wear of water pump seals or blockage of radiator passages. Using tap water may cause engine damage.

The factory provides a 50/50 solution of antifreeze and water in this

ATV. This coolant solution is recommended for most operating temperatures and provides good corrosion protection.

Decreasing the concentration of antifreeze to less than 40% will not provide proper corrosion protection.


119

１１／０５／０９１３：１７：０１３１ＨＰ４６５００１２９

Coolant

Increasing the concentration of antifreeze is not recommended because it decreases cooling system performance. Higher concentrations of antifreeze (up to 60%) should only be used to provide additional protection against freezing. Check the cooling system frequently during freezing weather.

Checking & Adding Coolant


Check the engine coolant level each day before operating your ATV and add if needed.

Air Cleaner


Proper air cleaner maintenance is very important for off-road vehicles.

A dirty, water-soaked, worn-out, or defective air cleaner will allow dirt, dust, mud, and other impurities to pass into the engine.

Service the air cleaner more frequently if you ride in unusually wet or dusty areas. Your dealer can help you determine the correct service interval for your riding conditions.

Your ATV’s air cleaner has very specific performance requirements.

Use a new Honda Genuine air cleaner specified for your model or an air cleaner of equal quality.

Using the wrong air cleaner may result in premature engine wear.

Proper air cleaner maintenance can prevent premature engine wear or damage, expensive repairs, low engine power, poor gas mileage, and spark plug fouling.

Improper or lack of proper air cleaner maintenance can cause poor perf ormance and premature engine wear.

Suspension

Your front and rear suspension systems use springs and hydraulic damping devices that suspend your weight and most of the weight of your ATV.

The oil damper systems hydraulically control the natural compression and rebound of the suspension springs so that traction and comfort are maintained as the wheels ride over rough terrain.

(Except TRX420TM)

The spring pre-loads for your front and rear suspension systems adjust the amount of force required to begin compression of the spring.

Consider adjusting your suspensions pre-load whenever you change your normal load, by adding or subtracting cargo, accessories, or when riding conditions change.

The way you ride your ATV and the type of ride you want to experience can also influence your suspension needs.

Lower spring pre-load provides a softer ride and is usually preferred for light loads and smooth terrain. Higher spring pre-load provides a firmer ride and is recommended for heavy loads and rough terrain.

Suspension Adjustment (Except TRX420TM )

Using a pin spanner, which is available from your dealer, the suspension can be adjusted for rider weight and riding conditions by changing the spring pre-load.

Do not attempt to disassemble, service, or dispose of the damper; see your dealer. The instructions found in this owner’s manual are limited to adjustments of the shock assembly only.

(rear) on your ATV dissipate heat generated by the friction of the brake pads on the disc (front) and the brake shoes on the drums (rear) as the wheels are slowed.

Hydraulic Disc Front Brake

As the front brake pads wear, brake fluid level will drop. A leak in the system will also cause the level to drop.

There are no adjustments to perform, but fluid level and pad wear must be inspected periodically. The system must be inspected frequently to ensure there are no fluid leaks.

If the right brake lever freeplay does not feel within the normal range while riding, check the brake pads for wear (page 146 ).

Worn pads should be replaced. If the pads are not worn beyond the recommended limit, there is probably air in the brake system. See your dealer to have the air bled from the system.

Mechanical Drum Rear Brake

If the rear brake lever/parking brake lever or brake pedal freeplay does not feel within the normal range while riding, check the brake shoes for wear (page 151 ).

Brake Fluid Recommendation

brake fluid Honda DOT 4 Brake Fluid

The recommended brake fluid is Honda DOT 4 Brake Fluid, or any brake fluid of equal quality and performance. Use fresh brake fluid from a sealed container. Be sure to read the label before opening the sealed container. An opened container may be contaminated or may have absorbed moisture from the air.

Fluid Level Inspection


If your inspection indicates a low fluid level, have your dealer add the recommended fluid.

Do not add or replace brake fluid, except in an emergency. If you do add fluid, have your dealer check the system as soon as possible.

Brake f luid can damage plastic and painted surf aces. Handle with care.

Wipe up spills immediately. Avoid brake fluid contact with skin or eyes.

If it comes in contact with your eyes, wash them out with clean water and immediately call a doctor. If it comes in contact with your skin, wash with clean water and, if necessary, call a doctor.

Tires

To safely operate your ATV, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated.

Using tires that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed.

Follow all instructions in this owner’s manual regarding tire inflation and maintenance.

This ATV is equipped with low pressure tubeless tires. Although the tires are designed specifically for off-road use, they are not immune to punctures. Always select your riding area with care.

The following pages give detailed information on how and when to check your air pressure, how to inspect your tires for wear and damage, and our recommendations for tire repair and replacement.

154


１１／０５／０９１３：２１：２７３１ＨＰ４６５００１６４

Tires

Air Pressure


Properly inflated tires provide the best combination of handling, tread life, and riding comfort. Generally, underinflated tires wear unevenly, adversely affect handling, and are more likely to fail from being overheated. Overinflated tires make your ATV ride harshly, are more prone to damage from surface hazards, and wear unevenly.

Make sure the air valve caps are secure. If necessary, install new caps.


155

１１／０５／０９１３：２１：３４３１ＨＰ４６５００１６５

Tires

Always check air pressure when your tires are ‘‘cold.’’ If you check air pressure when your tires are ‘‘warm’’ − even if your ATV has only been ridden for a few miles − the readings will be higher. If you let air out of warm tires to match the recommended cold tire pressures, the tires will be underinflated. Be sure to check tire pressure at the riding site, since changes in altitude can affect air pressure.

The recommended ‘‘cold’’ tire pressures are:

(TRX420TM/FM)

FRONT

RECOMMENDED

PRESSURE

REAR

3.6 psi (25.0 kPa) 3.6 psi (25.0 kPa)

(TRX420FPM)

156


１１／０５／０９１３：２１：４２３１ＨＰ４６５００１６６

Tires

A manually operated tire pump should be used rather than the high pressure system found in service stations. This will minimize the possibility of tire damage from overinflation. If you use a high pressure system at a service station, add air in small amounts and check the pressure increase frequently to prevent possible tire damage from overinflation.

Operating this ATV with improper tires, or with uneven tire pressure may cause loss of control, and you could be seriously injured or killed.

Always use the size and type tires specified in this owner’s manual for this vehicle.

Always maintain proper tire pressure as described in this owner’s manual.

Inspection


Whenever you check the tire pressures, you should also look for:

Bumps or bulges in the side of the tire or the tread. Replace any tire that has a bump or bulge.

Cuts, slits, or cracks in the tires. Replace the tire if you can see fabric or cord.

Nails or other foreign objects embedded in the side of the tire or tread.

Excessive tread wear.

Tire Repair


A tire that is repaired, either temporarily or permanently, will have lower speed and performance limits than a new or undamaged tire.

A temporary repair can sometimes be made in an emergency situation.

However, since a temporary repair may not hold, you must ride very slowly, preferably without any cargo, and have the tire replaced or permanently repaired as soon as possible. (For more information on temporary repairs, see If You Have a Flat Tire, page 191 .)

A permanent repair, such as an internal plug patch, can be made if a tire has only a small puncture in the tread area. However you may not be able to safely carry as much weight. If you choose to have a tire repaired, be sure the repair work is performed by a professional.

If you have a tire professionally repaired at a non-Honda facility, we recommend that you have the work checked by your dealer.


159

Tires

Tire Replacement


The tires that came on your ATV were designed to match the performance capabilities of your ATV and provide the best combination of handling, braking, and comfort.

It is best to replace all four tires, however if that is not possible, you must replace the tires in pairs (front or rear) with tires of the same size and type as the originals. Never replace just one tire.

Installing improper tires on your ATV can affect handling and stability. This can cause a crash in which you can be seriously hurt or killed.

Always use the size and type of tires recommended in this owner’s manual.

Battery

Your ATV has a maintenance-free type battery. You do not have to check the battery electrolyte level or add distilled water as you would with a conventional-type battery.

Your battery is a maintenance-f ree type and can be permanently damaged if the cap strip is removed.

Electrical accessories use current from the battery, even when the ignition is OFF. Limited operation also allows the battery to discharge.

If you have electrical accessories on your ATV or do not ride frequently, we recommend that you charge the battery frequently (see Battery

Charging, page 169 ).

If you do not expect to ride your ATV for at least two weeks, we recommend you remove the battery, or at least disconnect the battery cables (negative cable first).

If you plan to store your ATV, see Battery Storage, page 166 .

If your battery seems weak and/or is leaking electrolyte (causing slow starting or other electrical problems), see your dealer.

WARNING: Battery posts, terminals and related accessories contain lead and lead compounds.

Wash your hands after handling.

Battery

Battery Storage


If you plan to store your ATV, we recommend you remove the battery and store it where it can be charged at least every 30 days to maintain its service life.

If you do not remove the battery, we recommend disconnecting the battery cables (negative cable first).

You will get the best storage results from removing the battery and slow charging it every 30 days (see Battery Charging, page 169 ).

Before you remove the battery, be sure to read all the information that follows, as well as the information on the battery label.

The battery gives off explosive hydrogen gas during normal operation.

A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you.

Wear protective clothing and a face shield, or have a skilled mechanic do the battery maintenance.

１１／０５／０９１３：２３：２１３１ＨＰ４６５００１７９

Appearance Care

Frequent cleaning and polishing will keep your Honda looking newer longer.

Frequent cleaning also identifies you as an owner who values his ATV.

A clean ATV is also easier to inspect and service.

General Recommendations


To clean your ATV, you may use:

− water

− a mild, neutral detergent and water

− a mild spray and wipe cleaner/polisher

− a mild spray and rinse cleaner/degreaser and water

Avoid products that contain harsh detergents or chemical solvents that could damage the metal, paint, and plastic on your ATV.

If your ATV is still warm from recent operation, give the engine and exhaust system time to cool off.

Park in a shady area. Washing your ATV in bright sunlight may cause the finish to fade because water droplets intensify the sun’s brightness.

Spotting is also more likely because surface water can dry before you have time to wipe it off.

Clean your ATV regularly to protect surface finishes.

We recommend the use of a garden hose to wash your ATV. High pressure washers (like those at coin-operated car washers) can damage certain parts of your ATV.

High pressure water (or air) can damage certain parts of your ATV.

After cleaning, inspect for damage, wear, and leaks (fuel, oil, coolant and brake fluid).

172


１１／０５／０９１３：２３：４８３１ＨＰ４６５００１８２

Appearance Care

Finishing Touches


After washing your ATV, consider using a commercially available spray cleaner/polish or quality liquid or paste wax to finish the job. Use only a non-abrasive polish or wax made specifically for motorcycles or automobiles. Apply the polish or wax according to the instructions on the container.

If a surface on your ATV is chipped or scratched, your dealer has touchup paint to match your ATV’s color. Be sure to use your ATV’s color code (page 209 ) when you buy touch-up paint.

If the frame has a chip that exposes the metal, first apply primer (to prevent corrosion) and then apply the touch-up paint. Several thin layers of touch-up paint are better than one thick coat.

Exhaust Pipe and Muffler Maintenance

The exhaust pipe and muffler are stainless steel but may become stained by mud or dust.

To remove mud or dust, use a wet sponge and a liquid kitchen abrasive, then rinse well with clean water. Dry with chamois or a soft towel.

If necessary, remove heat stains by using a commercially available fine texture compound. Then rinse by the same manner as removing mud or dust.

Preparing for a Ride

A safe and enjoyable ride begins with good planning and preparation.

Always ride with at least one other person in case you have trouble, and let someone know where you’re going and when you expect to return.

Before riding in an unfamiliar area, find out in advance if you need special permits, get maps so you can study the terrain, and talk to other riders who know the area. The Forest Service and the Bureau of Land

Management, riding clubs, and off-road magazines are good sources of information.

What to Take to the Riding Area

Along with your ATV and riding gear, you should take along some tools and supplies in case you have a problem. For some of the difficulties you might encounter, see Taking Care of the Unexpected, which begins on page 185 .

We recommend that you always take water, food, a first aid kit, and your owner’s manual. Other items you should consider loading on your truck or trailer include: a tool kit tire repair supplies and tools, and tires extra parts, control levers, cables, and spark plugs wire, duct tape, and rope extra gasoline

For safety, all refueling should be done at a gas station on the way to the riding area or at your base camp.

You & the Environment

Owning and riding an ATV can be enjoyable, but you must do your part to protect nature. When you show respect for the land, wildlife, and other people, you also help preserve the sport of off-road riding.

Following are tips on how you can be an environmentally responsible

ATV owner.

Tread Lightly.

Stay on existing roads and trails, avoid surfaces that are easily damaged, and ride only in areas approved for off-road vehicles.

Keep the Noise Down.

Loud vehicles can be offensive. Ride as quietly as possible, don’t remove your spark arrester, and don’t modify the muffler or any other part of your air intake and exhaust systems. Such modifications not only increase noise, they also reduce engine performance and may be illegal.

Choose Sensible Cleaners.

Use a biodegradable detergent when you wash your ATV. Avoid aerosol spray cleaners that contain chlorofluorocarbons (CFCs) which damage the atmosphere’s protective ozone layer. Don’t throw cleaning solvents away; see the following guidelines for proper disposal.

Recycle Wastes.

It’s illegal and thoughtless to put used engine oil in the trash, down a drain, or on the ground. Used oil, gasoline, and cleaning solvents contain poisons that can hurt refuse workers and contaminate our drinking water, lakes, rivers, and oceans. Before changing your oil, make sure you have the proper containers. Put oil and other toxic wastes in separate sealed containers and take them to a recycling center. Call your local or state office of public works or environmental services to find a recycling center in your area, and to get instructions on how to dispose of non-recyclable wastes.

General Guidelines

Keeping your ATV well-maintained is the best way to reduce the possibility of having a problem while riding. However, problems can arise even with well-maintained machines.

Remember to take along your owner’s manual, the tool kit that came with your ATV, and any other items (such as tire repair supplies and additional tools) that might help you solve a problem on your own.

If something goes wrong during a ride, the first thing to do is stop as soon as you safely can. Do not continue riding if you have a flat tire, or you hear an unusual noise, or your ATV just doesn’t feel right. If you continue riding, you could cause more damage and endanger your own safety.

After stopping, take time to assess the situation. Carefully inspect your

ATV to identify the problem, then consider your options before you decide what to do.

If a problem is relatively minor and you have the tools, supplies, and skills to make a permanent repair, you may be able to fix it on the trail and continue riding. Or, you may be able to make a temporary repair that allows you to slowly ride back to your base where you can make a permanent repair or get help.

When a problem is more serious − or you don’t have the tools, supplies, experience, or time to deal with it − you need to choose the safest way to get yourself and your ATV back to base. For example, if you are close enough, you (or you and another person) might be able to push it back.

186


１１／０５／０９１３：２５：２１３１ＨＰ４６５００１９６


Should you ever have a problem while riding, please follow these guidelines:

Always put personal safety first.

Take time to assess the situation and your options before deciding what to do.

If the problem is relatively minor and you have the tools, supplies, and skills to make a temporary repair, be sure to have permanent repairs made as soon as possible.

Do not continue riding if you are hurt or your ATV is not in safe riding condition.

Additional recommendations for specific problems follow.

If Your Engine Quits or Won’t Start

Proper operation and maintenance can prevent starting and engine performance problems. In many cases, the cause of the problem may be a simple operational oversight.

If you have a problem starting the engine − or experience poor engine performance − the following information may help you. If you can’t correct the problem, see your dealer.

If your ATV won’t start, listen as you press the start button. If you don’t hear the starter motor turning, refer to the Starter motor doesn’t operate symptom. If you can hear the starter motor working normally, refer to the Starter motor works, but the engine won’t start symptom.

If You Have a Flat Tire

How you handle a flat tire on the trail depends on how serious the tire damage is, and what tools and supplies you have with you.

If you have a slow leak or a minor puncture, use the plug method to make a temporary repair. (The plug method is applied from the outside of the tire and is the same as that for conventional tubeless tires.)

A plug-type repair kit, available at most auto parts stores or service stations, provides a plug, an installation tool, tire cement, and an instruction sheet. Follow the instructions provided with the repair kit to make a temporary repair.

As soon as possible, have the tire permanently repaired by your dealer.

Any tire that cannot be repaired should be replaced.

Whenever the ATV is to be operated far from service facilities or available transportation, we recommend that you carry a tire pump and a repair kit with the vehicle.

If the leak is more serious, or a temporary repair doesn’t hold, the tire must be replaced. The tire will also need to be replaced if it is damaged

(page 160 ). Replacing a tire involves removing and re-installing the wheel (page 193 ).

If you are unable to repair a flat tire on the trail, you will need to send for help. We strongly recommend that you do not try to ride with a flat tire. The ATV will be hard to handle, and if the tire comes off the rim, it may lock up the wheel and cause you to crash.


191

１１／０５／０９１３：２６：０９３１ＨＰ４６５００２０１


Riding your ATV with a temporary tire repair can be risky.

If the temporary repair fails, you can crash and be seriously injured or killed. If you must ride with a temporary tire repair, ride slowly and carefully until the tire is permanently repaired or replaced.

１１／０５／０９１３：２６：３１３１ＨＰ４６５００２０４

If the High Coolant Temperature

Indicator Lights

Normally, the high coolant temperature indicator will only light momentarily when you turn the ignition ON ( ). Occasionally, it may flicker at or near idling speed.

High coolant temperature may be caused by restriction of air flow to the radiator (such as mud caked on the radiator), extended idling, an oil leak, a coolant leak, a low oil level, a low coolant level, or extended operation under adverse conditions.

If the indicator comes on while you’re riding, don’t ignore it. Pull safely to a stop. Stop the engine as soon as it’s safe to do so, and let it cool.

Continuing to ride with high coolant temperature or an overheated engine can cause serious engine damage.

A steaming engine indicates a coolant leak. Shut the engine off and wait until the steaming stops. Look for a leak, but don’t touch the engine or radiator system. Let everything cool off first.

Check for any restriction of air flow to the radiator.

If there’s no obvious problem, leave the engine on so the fan and coolant circulating system can continue working. Monitor the high coolant temperature indicator. The indicator may turn off after a brief stop with no load on the engine.

Check the radiator fan.

If the fan is not working, turn the engine off. Open the fuse box

(page 198 ) and check the radiator fan fuse. If the fuse is blown, replace it with the proper (same rating) spare fuse. Start the engine. If the high coolant temperature indicator comes on and stays on, turn the engine off.

If the radiator fan is working, visually check the coolant level in the reserve tank, located under the rear fender. It isn’t necessary to touch the radiator system.


195

１１／０５／０９１３：２６：３９３１ＨＰ４６５００２０５

If the High Coolant Temperature

Indicator Lights

If the reserve tank is low or empty, don’t ride without adding coolant

(page 120 ). After adding coolant, turn the engine on and check the high coolant temperature indicator.

If the indicator doesn’t turn off, do not ride. The engine needs repair.

Transport your ATV to your dealer (page 178 ).

If the temperature drops to normal, check the coolant level. If it has gone down, add more coolant.

Check for an oil leak.

Check the oil level. If necessary, add the recommended oil (page 108 ) to the upper level mark. If you must leave your ATV to get oil, secure it as much as possible.

Start the engine, and check that the high coolant temperature indicator goes off.

If you are able to resume riding, continue to monitor the high coolant temperature indicator frequently.

If there is an oil leak − do not ride the ATV until the leak is repaired by your dealer (page 178 ).

If there’s a mild coolant leak, you can ride for awhile, carefully watching the indicator. Be prepared to stop and add more coolant or water. If the leak is bad, transport your ATV to your dealer (page 178 ).

１１／０５／０９１３：２６：４８３１ＨＰ４６５００２０６

If a Fuse Blows

All of the electrical circuits on your ATV have fuses to protect them from damage caused by excess current flow (short circuit or overload).

If something electrical on your ATV stops working, the first thing you

Check all the fuses before looking elsewhere for another possible cause of the problem. Replace any blown fuses and check component operation.

If a Fuse Blows

If you do not have a spare fuse and you cannot ride the ATV without fixing the problem, take a fuse of the same rating or a lower rating from one of the other circuits that you can do without temporarily.

If you replace a blown fuse with a spare fuse that has a lower rating, replace the fuse with the correct rating as soon as you can. Also remember to replace any spare fuses that were installed.

If the replacement fuse of the same rating burns out in a short time, there is probably a serious electrical problem on your ATV. Leave the blown fuse in that circuit and have your ATV checked by your dealer.


201

１１／０５／０９１３：２７：２３３１ＨＰ４６５００２１１

If You Crash

Personal safety is your first priority after a crash. If you or anyone else has been injured, take time to assess the severity of the injuries and whether it is safe to continue riding. If you cannot ride safely, send someone for help. Do not ride if you will risk further injury.

If you decide you are capable of riding safely, carefully inspect your

ATV for damage and determine if it is safe to ride. Check the tightness of critical nuts and bolts securing such parts as the handlebar, control levers, brakes, and wheels.

If there is minor damage, or you are unsure about possible damage but decide to try riding the ATV back to your base, ride slowly and cautiously.

Sometimes, crash damage is hidden or not immediately apparent. When you get home, thoroughly check your ATV and correct any problems you find. Also, be sure to have your dealer check the frame and suspension after any serious crash.

If you lose your key and aren’t carrying a duplicate, either get your spare or have one made. If you don’t know your key number, call the dealer where you purchased your Honda ATV. They may have it listed in their records. If they don’t, transport your ATV to them or the nearest dealer. The dealer will probably have to remove the ignition switch assembly to find the key number so they can make a key for you.

１１／０５／０９１３：２７：３２３１ＨＰ４６５００２１３

If the Battery Is Low (or Dead)

Jump starting is not recommended, especially if you use an automobile battery. The greater amperage of an automobile battery when the car engine is running can damage your ATV’s electrical system.

Bump starting is also not recommended.

If you can’t charge the battery or it appears unable to hold a charge, contact your dealer.

204


１１／０５／０９１３：２７：３６３１ＨＰ４６５００２１４

If a Component Fails

The brake levers or pedal, control cables, and other components can be damaged as you ride in dense brush or over rocky terrain. Making a trailside repair depends on how serious the damage is and what tools and supplies you have with you.

If any component of the brake system is damaged, you may be able to ride carefully back to your base using the other brake components for slowing or stopping.

If you damage a throttle cable or other critical component, your ATV may be unsafe to ride. Carefully assess the damage and make any repairs that you can. But if there is any doubt, it’s best to be conservative and safe.

216


１１／０５／０９１３：２９：３６３１ＨＰ４６５００２２６


Source of Exhaust Emissions

The combustion process produces carbon monoxide (CO), oxides of nitrogen (NOx) and hydrocarbons (HC). Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight.

Carbon monoxide does not react in the same way, but it is toxic.

Honda Motor Co., Ltd. utilizes various systems to reduce carbon monoxide, oxides of nitrogen and hydrocarbons.

Exhaust Emission Control System

The exhaust emission control system includes a PGM-FI system.

No adjustment to this system should be made although periodic inspection of the components is recommended.

The exhaust emission control system is separate from the crankcase emission control system.

Crankcase Emission Control System

The engine is equipped with a closed crankcase system to prevent discharging crankcase emissions into the atmosphere. Blow-by gas is returned to the combustion chamber through the air cleaner.


217

１１／０５／０９１３：２９：４２３１ＨＰ４６５００２２７


Problems That May Affect ATV Exhaust Emissions

If you are aware of any of the following symptoms, have the vehicle inspected and repaired by your ATV dealer.

Symptoms:

1.

Hard starting or stalling after starting

2.

3.

Rough idle

Misfiring or backfiring during acceleration

4.

5.

After-burning (backfiring)

Poor performance (driveability) and poor fuel economy

Federal regulations prohibit removing or disabling a device or element of design that may affect your engine’s emission performance unless your ATV will be used exclusively in competition. If you modify your engine for use in sanctioned competition events, you must deface or destroy the emission control information label.

Oxygenated Fuels

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States use oxygenated fuels to help reduce emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel’s contents.

Some states/provinces require this information to be posted on the pump.

The following are the EPA-approved percentages of oxygenates:

ETHANOL (ethyl or grain alcohol) 10% by volume

You may use gasoline containing up to 10% ethanol by volume.

Gasoline containing ethanol may be marketed under the name

‘‘Gasohol’’.

MTBE (Methyl Tertiary Butyl Ether) 15% by Volume

You may use gasoline containing up to 15% MTBE by volume.

METHANOL (methyl or wood alcohol) 5% by Volume

You may use gasoline containing methanol containing up to 5% methanol by volume as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of your fuel system.

220


１１／０５／０９１３：２９：５９３１ＨＰ４６５００２３０

Oxygenated Fuels

If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.

Oxygenated fuels can damage paint and plastic. Be careful not to spill fuel when filling the fuel tank. Wipe up any spills immediately.

Oxygenated f uels can damage paint and plastic. Damage caused by spilled f uel is not covered by warranty.

Authorized Manuals

The Service Manual used by your authorized dealer is available from your Honda dealer or Helm, Inc.

Also available but not necessary to service your model is the Honda

Common Service Manual which explains theory of operation and basic service information for various systems on Honda motorcycles, scooters, ATVs, MUVs and PWCs.

These Honda manuals are written for the professional technician, but most mechanically capable owners should find them easy to use if they have the proper tools and observe proper safety standards.

Special Honda tools are necessary for some procedures.

Warranty Coverage

Your new Honda is covered by these warranties:

TRX Limited Warranty

Emission Control System Warranty

There are responsibilities, restrictions, and exclusions which apply to these warranties. Please read the Warranties Booklet given to you by your Honda dealer at the time of purchase. Be sure to keep your Honda owner’s card with your Warranties Booklet.

It is important to realize that your warranty applies to defects in material or workmanship of your Honda. Your warranty coverage does not apply to normal wear or deterioration associated with using the ATV.

Your warranty coverage will not be voided if you choose to perform your own maintenance. However, you should have the proper tools and service information, and be mechanically qualified. Failures that occur due directly to improper maintenance are not covered.

Almost all of your warranty coverage can be extended through the

Honda Protection Plan. For more information, see your dealer.


225

１１／０５／０９１３：３０：２５３１ＨＰ４６５００２３５

Warranty Service

Please remember that recommended maintenance interval servicing is not included in your warranty coverage. Additionally, your warranty does not apply to the normal wear of items (such as brakes, tires, etc.).

If you believe you have a problem with your ATV, call the service department of your dealer. Make an appointment for an inspection and diagnosis. Remember, as the owner of the ATV, you will be asked to authorize that inspection. Your dealer will give you the results of the inspection. If the problem is covered under warranty, your dealer will perform the warranty repairs for you.

If you have questions about warranty coverage or the nature of the repair, it is best to talk to the Service Manager of your dealer.

Sometimes, in spite of the best intentions of all concerned, a misunderstanding may occur. If you aren’t satisfied with your dealer’s handling of the situation, we suggest you discuss your problem with the appropriate member of the dealership’s management team. If the problem has already been reviewed with the Service Manager, Parts

Manager, Sales Manager, etc., contact the Owner of the dealership or their designated representative.

Contacting Honda

Your owner’s manual was written to cover most of the questions you might ask about your Honda. Any questions not answered in the owner’s manual can be answered by your dealer. If your dealer doesn’t have the answer right away, they will get it for you.

If you have a difference of opinion with your dealer, please remember that each dealership is independently owned and operated. That’s why it’s important to work to resolve any differences at the dealership level.

If you wish to comment on your experiences with your Honda or with your dealer, please send your comments to the following address:

Motorcycle Division, American Honda Motor Co., Inc., P.O. Box 2200,

Torrance, CA 90509-2200, mailstop: 100-4C-7B, telephone: (866) 784-

1870.

Please include the following information in your letter: name, address, and telephone number product model, year, and VIN date of purchase dealer name and address

We will likely ask your dealer to respond, or possibly acknowledge your comments directly.

Quick Reference

The following is a brief, but important collection of information you need to know about your Honda. You’ll also find space to record important notes.

How To Avoid Costly Repairs

The engine of your Honda can be the most expensive component to repair. Proper maintenance, especially the use of the recommended fluids and filters, prevents premature wear and damage.

Frequent causes of costly repairs are:

Engine oil –– insufficient quantity, improper oil.

Air cleaner –– dirty, leaking because of improper installation (poor seal).
