Page 110: Braking
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 TRX420TE1/TM1: Although the front and rear brakes have separate controls, all four wheels are interconnected when your ATV is in the 4WD mode.
Page 111 Braking 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.
Page 112: Riding Your Atv
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. WARNING WARNING Turning improperly can make the ATV go out of control, causing a collision or overturn.
Page 113 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.
Page 114: Skidding Or Sliding
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.
Page 115: Riding Up Hills
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.
Page 116 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.
Page 117 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. WARNING WARNING Stalling, rolling backwards or improperly...
Page 118 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.
Page 119: Riding Down Hills
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. WARNING WARNING Going down a hill improperly could cause loss of control or cause the ATV to overturn.
Page 120: Crossing Or Turning On Hills Or Slopes
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.
Page 121 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.
Page 122: Riding Over Obstacles
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.
Page 123: Riding Through Water
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. WARNING WARNING The ATV tires have some ability to float.
Page 124 Riding Your ATV 5. 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.
Page 125: Parking
Parking 1. Look for level parking area. Make sure the ground surface is firm. 2. After bringing your ATV to a stop, hold the brakes while you shift into neutral. 3. Set the parking brake. 4.

Tips Here’s helpful advice on how to prepare for an off-road adventure, Tips how to transport and store your Honda, and how to be an environmentally responsible ATV owner. Preparing for a Ride ..............218 What to Take to the Riding Area..........218 What to Take on the Trail ............
Page 227: Preparing For A Ride
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.
Page 228: What To Take On The Trail
Preparing for a Ride What to Take on the Trail What you take with you during a ride depends on the kind of terrain, how long you expect to ride, how far you might go from your base camp or help, and how experienced you or your companions are in making repairs.
Page 229: Transporting Your Honda
Transporting Your Honda Do not tow your ATV behind a car or other vehicle. When you transport your ATV, we recommend that you carry the vehicle in its normal operating position (on all four wheels). Do not incline the vehicle upright on its rear end. This can damage the vehicle, and leaking gasoline could be a hazard.
Page 230 Transporting Your Honda 2. Secure the vehicle with tie-down straps in the areas shown. • Suitable tie-down straps are available from your dealer. • Ordinary rope is not recommended because it can stretch under load. • Using tie-down straps in any other areas can damage your ATV.
Page 231: Storing Your Honda
That way, needed repairs won’t be forgotten and it will be easier to get your ATV running again. For more information about storage, refer to the Honda Winter Storage Guide, available from your dealer (USA only). We suggest you perform the following procedures to keep your ATV in top condition.
Page 232: Preparation For Storage
Storing Your Honda Preparation for Storage Refer to Safety Precautions on page 121. 1. Change the engine oil and filter (page 148, 152). 2. Make sure the cooling system is filled with a 50/50% antifreeze solution (page 160). 3. Fill the fuel tank. Make sure the fuel fill cap is properly installed.
Page 233 Storing Your Honda 5. Remove the battery and charge it fully. Store it in an area protected from freezing temperatures and direct sunlight. Slow charge the battery (page 212) once a month. WARNING WARNING The battery gives off explosive hydrogen gas during normal operation.
Page 234: Removal From Storage
Storing Your Honda Removal from Storage Refer to Safety Precautions on page 121. 1. Uncover and clean your ATV. 2. If your ATV has been stored for more than four months — change the engine oil (page 148, 152). 3. If your ATV has been stored for more than two months — ask your dealer to drain and replace the fuel.
Page 235: You & The Environment
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.
Page 236: Taking Care Of The Unexpected
Taking Care of the Unexpected With all the challenges you can encounter off-road, there’s a chance Taking Care of the Unexpected that sometime something may go wrong. This section gives practical advice to help you deal with a wide range of problems. Take time to read this section before you ride.
Page 237: General Guidelines
Taking Care of the Unexpected 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.
Page 238 Taking Care of the Unexpected 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.

Page 254: If The High Coolant Temperature Indicator Lights
If the High Coolant Temperature Indicator Lights Normally, the high coolant temperature indicator will only light momentarily when you turn the ignition to ON (q). 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.
Page 255 If the High Coolant Temperature Indicator Lights • If the reserve tank is low or empty, don’t ride without adding coolant (page 161). After adding coolant, turn the engine on and check the coolant temperature gauge (Except TRX420TM1) and high coolant temperature indicator. If the indicator doesn’t turn off, do not ride.
Page 256: If A Fuse Blows
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 should check for is a blown fuse (1).
Page 257 If a Fuse Blows Main and Shift Motor Fuses (TRX420TE1/FE1/FA2) Access 1. To prevent an accidental short circuit, turn the ignition switch to OFF (w) before checking or replacing the fuses. 2. Remove the seat (page 133). 3. Remove the rear fender cover (page 136). 4.
Page 258 If a Fuse Blows Circuit Fuses Access TRX420TM1/FM1/FM2 TRX420TE1/FE1/FA2 (7) circuit fuses (8) spare fuses 6. To check or replace a circuit fuse (7), pull the old fuse out of its retaining clips with the fuse puller on the underside of the rear fender cover (page 132).
Page 259 If a Fuse Blows EPS (Electric Power Steering) Fuse Access (TRX420FM2/FA2) 1. Turn the ignition switch to OFF (w) before checking the fuse. 2. Remove the seat (page 133). 3. Remove the rear fender cover (page 136). 4. To access the EPS fuse (1), remove the EPS fuse box cover (2). If the EPS fuse is blown, see your dealer for this service.
Page 260 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.
Page 261: If You Crash
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.
Page 262: If You Lose Your Key
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.
Page 263: If The Battery Is Low (Or Dead)
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.
Page 264: If A Component Fails
