FUEL AND OIL

RECOMMENDATIONS

FUEL

Your vehicle requires regular unleaded gasoline, with a minimum pump octane rating of 87

((R+M)/2 method). In some areas, the only fuels that are available are oxygenated fuels.

Oxygenated fuels which meet the minimum octane requirement and the requirements described below may be used in your ATV without jeopardizing the New Vehicle Limited Warranty or the Emission

Control System Warranty.

NOTE: Oxygenated fuels are fuels which contain oxygen-carrying additives such as MTBE or alcohol.

Gasoline containing MTBE

Unleaded gasoline containing

MTBE (Methyl Tertiary Butyl

Ether) may be used in your ATV if the MTBE content is not greater than 15%. This oxygenated fuel does not contain alcohol.

Gasoline/Ethanol Blends

Blends of unleaded gasoline and ethanol (grain alcohol), also known as GASOHOL, may be used in your ATV if the ethanol content is not greater than 10%.

Gasoline/Methanol

Fuels containing 5% or less methanol (wood alcohol) may be suitable for use in your ATV if they contain co-solvents and corrosion inhibitors.

DO NOT USE fuels containing more than 5% methanol under any circumstances. Fuel system damage or ATV performance problems resulting from the use of such fuels are not the responsibility of Suzuki and may not be covered under the New Vehicle

Limited Warranty or the Emission

Control System Warranty.

Fuel Pump Labeling

In some states, pumps that dispense oxygenated fuels are required to be labeled for the type and percentage of oxygen, and whether important additives are present. Such labels may provide enough information for you to determine if a particular blend of fuel meets the requirements listed above. In other states, pumps may not be clearly labeled as to the content or type of oxygen and additives. If you are not sure that the fuel you intend to use meets these requirements, check with the service station operator or the fuel supplier.

1-2

www.quad-forum.sk

NOTE:

• To help minimize air pollution,

Suzuki recommends that you use oxygenated fuels.

• Be sure that any oxygenated fuel you use has octane ratings of at least 87 pump octane ((R+M)/2 method).

• If you are not satisfied with the driveability or fuel economy of your ATV when you are using an oxygenated fuel, you should switch back to regular unleaded gasoline.

• If you are not satisfied with the driveability of your ATV when you are using an oxygenated fuel, or if engine pinging is experienced, substitute another brand as there are differences between brands.

ENGINE OIL

Oil quality is a major contributor to your engine’s performance and life. Always select good quality engine oil. Suzuki recommends the use of SUZUKI PERFOR-

MANCE 4 MOTOR OIL or equivalent engine oil. Use oil with an API

(American Petroleum Institute) classification of SF/SG or SH/SJ, or with a JASO classification of

MA.

JASO T903

The JASO T903 standard is an index to select engine oils for 4stroke motorcycle and ATV engines. Motorcycle and ATV engines lubricate clutch and transmission gears with engine oil. JASO T903 specifies performance requirements for motorcycle and ATV clutches and transmissions.

Energy Conserving

Suzuki does not recommend the use of “ENERGY CONSERVING” oils. Some engine oils which have an API classification of SH or higher have an “ENERGY CON-

SERVING” indication in the API classification doughnut mark.

These oils can affect engine life and clutch performance.

There are two classes, MA and

MB. The oil container shows the classification as follows.

BREAK-IN

The first month is the most important in the life of your vehicle.

Proper operation during this break-in period will help assure maximum life and performance from your new vehicle. The following guidelines explain proper break-in procedures.

Allow the Engine Oil to

Circulate Before Riding

Allow enough idling time after warm or cold engine starting before revving the engine or placing the transmission in gear. This allows time for the lubricating oil to reach all critical engine components.

Maximum Throttle Opening

Recommendation

During the first 10 hours of operation, you should always use less than 1/2 throttle.

Vary the Engine Speed

Vary the engine speed during the break-in period. This allows the parts to “load” (aiding the mating process) and then “unload”

(allowing the parts to cool).

Although it is essential to place some stress on the engine components during break-in, you must be careful not to load the engine too much.

Observe Your Initial and Most

Critical Service

The initial service (break-in maintenance) is the most important service your vehicle will receive.

During break-in operation, all of the engine components will have mated together and seated. Maintenance required as part of the initial service includes correction of all adjustments, tightening of all fasteners and replacement of dirty oil. Timely performance of this service will help make sure you get the best service life and performance from the engine.

Avoid Constant Low Speed

Operating the engine at constant low speed (light load) can cause parts to glaze and not seat properly. Allow the engine to accelerate freely through the gears, without exceeding the maximum recommended throttle opening.



WARNING

Indicates a potential hazard that could result in injury or death.

BRAKING

To stop the LT-F400/F, first release the throttle lever. Next, apply the front and rear brakes evenly and at the same time. As vehicle speed decreases, shift down through the gears.



WARNING

Braking while turning the ATV can be hazardous.

Use of the brake when turning could cause the ATV to slide or roll over.

Use the brakes to slow down before you begin to turn.



WARNING

Braking hard on slippery surfaces can be hazardous.

The ATV can skid and go out of control if you brake too hard.

Apply the brakes lightly and with care on slippery surfaces.



WARNING

Operating the parking brake lock when the ATV is moving can be hazardous.

The rear wheels can lock, causing a skid and an accident.

Use the parking brake only after you stop the ATV.



WARNING

Braking on hills can be hazardous.

As the LT-F400F is four-wheel drive, using either the front brake alone or the rear brake alone will actually brake all four wheels. Therefore, any application of the brakes will result in braking force being applied to the downhill wheels. This could cause the vehicle to overturn.

Be extra careful when braking on a hill.

3-15

www.quad-forum.sk

TURNING



WARNING

Turning the ATV improperly can be hazardous.

Always follow proper procedures for turning as described in this section. Practice turning at low speeds before attempting to turn at faster speeds.

Never turn at excessive speeds.

To turn the LT-F400/F, use the following technique:

• Move your body weight forward and to the inside of the turn.

• Turn the handlebars while looking in the direction of the turn.

If you turn the ATV improperly, it may cause a collision or overturn.

To turn the LT-F400/F, the rider must use the proper technique.

Because this vehicle has a solid rear axle, both rear wheels always turn at the same speed. This means that if the rear wheels are getting equal traction, the vehicle will tend to move straight ahead.

This is because the rear wheels will travel the same distance. For the vehicle to turn, the outside rear wheel must travel a greater distance than the inside rear wheel. To make this happen, the rider must create less traction for the inside wheel, allowing it to slip somewhat. This allows it to travel a shorter distance than the outside wheel. This happens even though both wheels are still turning at the same speed.

For HIGHER SPEEDS or

SHARPER TURNS:

Use the same technique that you use for turning at low speeds, but move your body weight farther toward the inside of the turn to maintain your balance. Natural turning forces (which can push the vehicle to the outside of the turn) increase as speed or turn sharpness increases. This means you must lean your body farther into the turn as you go faster or turn more sharply. This prevents the vehicle from tipping over to the outside of the turn. If your ATV starts to tip while turning, lean your body farther into the turn while gradually reducing the throttle and making the turn wider, if possible.

3-16

www.quad-forum.sk

SKIDDING OR SLIDING



WARNING

Skidding or sliding improperly can be hazardous.

You may lose control of your

ATV, or 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.

You may experience skidding or sliding when you are not braking.

You may be able to overcome it by using the techniques listed below.

If your front wheel skids:

Gain front wheel traction by reducing the throttle opening and leaning your body weight slightly forward.

If your rear wheel skids:

If space permits, steer in the direction of the skid. Shift your body weight away from the skid slightly. Avoid using the throttle or brakes until you regain directional control of the vehicle.

3-17

Wet or frozen brakes will increase stopping distance.

This will increase your chance of having an accident.

Be sure to inspect the brakes before each use of the vehicle in cold weather as described above.

Continued exposure to cold temperatures can lead to hypothermia. Hypothermia is a condition where your body’s inner temperature drops low enough to cause injury or death.

Any water that enters the brakes while you ride may freeze after you park your ATV. The frozen water can prevent the wheels from turning or the brakes from working. After riding through water, mud, snow, or slush it is important to dry the brakes before parking the ATV. To dry the brakes, apply them several times while riding slowly. Before your next ride, be sure to do a pre-ride inspection as described earlier in this section.

Always dress for the worst weather conditions you might encounter. Be prepared for bad weather and ATV breakdowns.

Riding in cold weather can be hazardous. At a temperature of

10°F (–12°C), the wind chill created by going just 15 km/h (9 miles/h) makes you as cold as if you were standing still at a temperature of –9°F (–23°C). At this temperature, exposed flesh will freeze in just a few minutes.

Continued exposure to cold temperatures can also lead to hypothermia. Hypothermia occurs when your body’s inner temperature drops. Symptoms include numbness in the extremities (hands, feet, arms, and legs), and shivering. Damp clothing contributes to hypothermia because cold water on your skin will drain heat from your body’s core.

We strongly recommend that if you do any cold-weather riding, you familiarize yourself with the symptoms, treatment, and prevention of hypothermia. Information is available at libraries and through government agencies.

Riding your ATV on Snow and

Ice



WARNING

Riding on snow-covered terrain without care can be hazardous.

Plan your winter rides with safety and comfort in mind. Dress for the worst conditions you might encounter. Be prepared for bad weather and ATV breakdowns.

Wear warm, water-resistant clothing such as thermal underwear, snowmobile suits, lined gloves and boots, and wool socks.



WARNING

Wearing loose clothing when riding your ATV can be hazardous.

The snow may be covering rocks, holes, ice or other hazards that can cause a loss of control. Severe injury or death could occur if you lose control of the ATV.

Go slowly and be extra careful when riding on snow-covered terrain. Always be alert to changing terrain conditions when operating the ATV.

Loose clothing, such as a long scarf or shawl, can get caught in an ATV’s moving parts.



WARNING

Riding on a frozen lake or river can be hazardous.

Never wear loose clothing when riding your ATV.

Serious injury or death can occur if the ice breaks and you fall into the cold water.

Check with local authorities to verify the thickness of the ice and areas to avoid.

3-27

www.quad-forum.sk



WARNING

Failure to use extra care when operating on slippery surfaces such as hard-packed snow and ice can be hazardous.

Failure to use extra care can cause loss of traction or loss of vehicle control. This could result in an accident, including an overturn.

Do not operate on slippery surfaces until you have learned and practiced the skills necessary to control the ATV on such terrain. Always use extra care on slippery surfaces. Avoid snow- or ice-covered hills whenever possible.

Practice riding your ATV in an open snow- or ice-covered area, at slow speeds, before heading out on snow- or ice-covered trails.

Learn how your ATV responds to steering and braking on the type of terrain you will encounter on your ride.

Your eyes may be sensitive to sunlight when you ride over snow or ice on a bright, sunny day.

Snow or ice reflects more light into your eyes than dirt or grass does. Tinted eye protection will reduce the amount of light reaching your eyes. Always use clear eye protection when riding at night. On overcast days, you may find it helpful to use yellow-tinted eye protection.

Trailer Tongue Weight.

CAUTION

Towing a trailer during the break-in period can damage your ATV.

Trailer towing adds stress to the engine, drive train, and brakes.

Gross Trailer Weight is the weight of the trailer plus cargo in it. You can measure Gross Trailer Weight by putting each wheel of the fully loaded trailer on a bathroom scale. Add the weights shown on the scales.

Never tow a trailer during the first 10 hours that you ride your

ATV.

Tongue Weight is the downward force exerted on the hitch by the trailer coupler when the trailer is fully loaded and the coupler is at its normal towing height. This weight can be measured using a bathroom scale.

5-38

www.quad-forum.sk

The weight of your loaded trailer

(Gross Trailer Weight) should never exceed 180 kg (400 lbs) when towing on uneven surfaces.

When towing at low speed along a straight level path, you may tow up to the vehicle towing limit of

450 kg (992 lbs). Spread the cargo in your trailer so that the

Tongue Weight is about 10% of the Gross Trailer Weight. You can do this by placing about 60% of the total cargo weight in the front half of the trailer. Make sure the cargo weight is even between the right and left sides of the trailer.



WARNING

Overloading your trailer can be hazardous.

An overloaded trailer can affect the handling of the ATV.

Never overload your trailer.
