changing terrain conditions when operating the ATV.

 Never operate on excessively rough, slippery or loose terrain until you have learned and

practiced the skills necessary to control the ATV on such terrain, Always be especially cautions
on these kinds of terrain.

 Always follow proper procedures for turning as described in this manual. Practice turning at

low speeds before attempting to turn at faster speeds and never turns at excessive speeds.

 Never operate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller

hills before attempting larger hills.

14

 Always follow proper procedures for climbing hills as described in this manual. Check the

terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose
surfaces. Shift your weight forward. Never open the throttle suddenly. Never go over the top of
a hill at high speed.

 Always follow proper procedures for going down hills and for braking on hills as described in

this manual. Check the terrain carefully before you start down any hill. Shift your weight
backward. Never go down a hill at high speed. Avoid going down a hill at an angle that would
cause the vehicle to lean sharply to one side. Go straight down the hill where possible.

6. 2WD/4WD/LOCK SWITCH

The 2WD/4WD/LOCK SELECT BUTTON is used to change the engine drive power to two wheels or all
four wheels. Select 2WD, 4WD or LOCK based on different terrain conditions.

2WD: Engage the engine power on rear wheels only.

This is mainly used for normal riding.

4WD: Engage the engine power on all four wheels. There is a limited slip gear assembly inside the

front differential to engage the right and left front wheels at different speeds. 4WD provides
much more traction than 2WD and should be used when riding on wet and slippery surfaces.

LOCK: Engage the engine power on all four wheels without engaging the limited slip gear assembly.

This provides traction to all four wheels evenly and should be used when two or more
wheels lose traction.

2WD/4WD/LOCK Switch:
2WD/4WD

WARNING!

Always stop the ATV before changing from two-wheel drive to four-wheel drive and vice
versa. The ATV handles differently in two-wheel drive than in four wheel drive in some
circumstances. Changing from the two-wheel drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly handle differently. This could distract the
operator and increase the risk of losing control and causing an accident.

This ATV is equipped with a switch to change from two-wheel drive to four-wheel drive and vice
versa. Select the appropriate drive according to the terrain and the conditions.

“2WD” (two-wheel drive): Power is supplied to the rear wheels.
“4WD” (four-wheel drive): Power is supplied to the rear and front wheels.

To change from two-wheel drive to four-wheel drive, stop the ATV and push the button in to the
“4WD” position. Then, the four-wheel-drive indicator ” “ is displayed on the in the
multi-function display.
To change from four-wheel drive to two-wheel drive, stop the ATV and push the button in to reset it
to the 2WD position. The two-wheel drive indicator is displayed on the multi-function display.

23

4WD/LOCK

WARNING!

Always ride at a slow speed when the ATV is in differential gear lock and allow extra time
and distance for maneuvers.
All wheels turn at the same speed when the differential gear is locked, so it takes more
effort to turn the ATV. The effort needed to turn increases with the riding speed. You may
lose control and have an accident if you cannot make a sharp enough turn for the speed you
are traveling.

This ATV is equipped with a switch allowing you to lock the differential gear when in four-wheel
drive. Select the appropriate switch position according to the terrain and the conditions.

 “4WD” (four-wheel drive): Power is supplied to the rear and front wheels.
 “LOCK” (four-wheel drive with the differential gear locked): Power is supplied to the rear and

front wheels and the differential gear is locked. Unlike in four-wheel drive, all wheels turn at

the same speed.
To lock the differential gear in four-wheel drive, make sure the four-wheel drive button is pushed in
to the “4WD” position.

24

Stop the ATV, make sure the 4WD button is pushed in, then turn the differential gear lock lever to
the LOCK position. When the differential gear is locked, the differential gear lock indicator “LOCK”
will come on along with the indicator “ “ in the multi-function display.

To release the differential gear lock, stop the ATV and turn the lock lever to the “4WD” position.
NOTE: Riding before the differential gear lock is properly engaged will cause the vehicle speed to be
limited until engagement is complete.

WARNING!

Turning the lock lever when the ATV is moving is extremely dangerous and you may lose
control of the vehicle. The gear box mechanism can be damaged if the lever is moved while
the ATV is in motion. Always stop the ATV completely before shifting between 2WD, 4WD
and LOCK.

7. TIRES

Check tire pressure regularly to make sure it is at the recommended specifications. Also check for
wear and damage.

Tire pressure

Use the low-pressure tire gauge to check and adjust tire pressure when tires are cold. Tire pressure
must be equal on both sides.

WARNING!

Operation of this vehicle with improper tire pressure may cause severe injury or death from
loss control or rollover. Tire pressure below the minimum specified could also cause the tire
to separate from the rim under severe riding condition.

25

Set the tire pressure to the following specifications:

Model

550 EFI 4x4

550 EFI 4x4 EPS

Recommend

Front

7 psi (0.492kgf/㎝2)

6 psi (0.422kgf/㎝2)

Rear

7 psi (0.492kgf/㎝2)

6 psi (0.422kgf/㎝2)

The low-pressure tire gauge is included as standard equipment. Make two measurements of the tire
pressure and use the second reading. Dust or dirt in the gauge could cause the first reading to be
incorrect.

Tire wear limit

When the tire tread depth decreases to .12 in. (3 mm) due
to wear, replace the tire.

Aftermarket tires and rims

The tires and rims that came with your ATV were designed to match the performance capabilities
and to provide the best combination of handling, braking and comfort. Other tires, rims, sizes and
combinations may not be appropriate.

8. COOLANT

The coolant level should be checked before each ride. In addition, the coolant must be changed at
the intervals specified in the periodic maintenance and lubrication chart.

To check the coolant level

1. Place the ATV on a level surface.

NOTE: The coolant level must be checked on a cold engine since the level varies with
engine temperature.

2. Check the coolant level in the coolant reservoir.

NOTE: The coolant should be between the minimum and maximum level marks.

If the coolant is at or below the minimum level mark, remove the coolant reservoir cap, add coolant
or distilled water to the maximum level mark and install the reservoir cap.

CAUTION!

If coolant is not available, use distilled water or soft tap water instead. Do not use hard
water since it is harmful to the engine. If water has been used instead of coolant, replace it
with coolant as soon as possible; otherwise the cooling system will not be protected against
frost and corrosion. If water has been added to the coolant, have a dealer check the
antifreeze content of the coolant as soon as possible, otherwise the effectiveness of the
coolant will be reduced.

※Coolant reservoir capacity ( up to the maximum level mark): 1.25 quarts (1.2 L)

To change the coolant

WARNING!

Wait for the engine and radiator to cool before removing the radiator cap. You could be
burned by hot fluid and steam blown out under pressure. Always place a thick rag over the
cap when opening. Allow any remaining pressure to escape before completely removing the
cap.

27

1. Place the ATV on a level surface. Turn the key to the OFF position and remove it from the

vehicle.

2. Remove front cover.

3. Place a container under the engine and then remove the coolant drain bolt and its gasket.

4. Remove the radiator cap.

5. Remove reservoir cap.

6. Disconnect the coolant reservoir hose on the coolant reservoir side and allow the coolant

to drain from the coolant reservoir.

7. After draining the coolant, thoroughly flush the cooling system with clean tap water.

8. Install the coolant drain bolt and its new gasket and then tighten the bolt.

9. Connect the coolant reservoir hose.

10. Pour the recommended coolant into the reservoir to the maximum level mark and then

install the reservoir cap.

CAUTION!

Mix antifreeze with distilled water only. However, if distilled water is not available, soft
water may be used for refilling. Do not use hard water since it is harmful to the engine.

11. Pour the recommended coolant into the radiator until it is full.

Antifreeze/water mixture ratio:

1:1

Recommended antifreeze:

High quality ethylene glycol antifreeze containing corrosion inhibitors for aluminum
engines.

Coolant quantity:

Radiator capacity (including all routes): 2.3 quarts (2.2 L)

You could collide with another vehicle.

Know the terrain where you ride. Ride cautiously in unfamiliar areas. Stay alert for holes, rocks or
roots in the terrain and other hidden hazards, which may cause the ATV to overturn.

WARNING!

The ATV could go out of control if you do not have enough time to react to hidden rocks,
bumps or holes. Go slowly and be extra careful when operating on unfamiliar terrain. Always
be alert to changing terrain conditions when operating the ATV.

Do not operate on 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.

47

WARNING!

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

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

WARNING!

You could collide with another vehicle if operating in off-road areas where you cannot easily
be seen. Mount a caution flag on the ATV to make you more visible. Watch carefully for
other vehicles.

Do not ride in areas posted “no trespassing”.
Do not ride on private property without getting permission.
Select a large and flat area off-road to become familiar with your ATV. Make sure that this area is
free of obstacles and other riders. You should practice control of the throttle, brakes, shifting
procedures and turning techniques in this area before trying more difficult terrain.
Shift to the park position and follow the instruction to start the engine. Once it has warmed up you
are ready to begin riding your ATV. With the engine idling, shift the drive select lever into the low
gear position or high gear position. Apply the throttle slowly and smoothly.
If the throttle is applied too abruptly, the front wheels may lift off the ground, resulting in a loss of
directional control. Avoid higher speeds until you are thoroughly familiar with operation of your
ATV.
When slowing down or stopping, release the throttle and apply the brakes smoothly and evenly.
Improper use of the brakes can cause the tires to lose traction, reducing control and increasing the
possibility of an accident.

CAUTION!

Do not shift from low gear to high gear without coming a complete stop. Damage to the
engine or drive train may occur.

TURNING YOUR ATV

WARNING!

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

48

To achieve maximum traction while riding off-road, the two rear wheels turn together at the same
speed. Therefore, unless the wheel on the inside of the turn is allowed to slip or lose some traction,
the ATV will resist turning. A special turning technique must be used to allow the ATV to make turns
quickly and easily. It is essential that this skill be learned first at low speed.
As you approach a curve, slow down and begin to turn the handlebars in the desired direction. As
you do so, put your weight on the footboard to the outside of the turn (opposite your desired
direction) and lean your upper body into the turn. Use the throttle to maintain an even speed
through the turn. This maneuver will let the wheel on the inside of the turn slip slightly allowing the
ATV to make the turn properly.
This procedure should be practiced at slow speed many times in a large off-road area with no

obstacles. If an incorrect technique is used, your ATV may continue to go straight. If the ATV doesn’t

turn, come to a stop and then practice the procedure again. If the riding surface is slippery or loose,
it may help to position more of your weight over the front wheels by moving forward on the seat.
Once you have learned this technique, you should be able to perform it at higher speeds or in
tighter curves.
Improper riding procedures such as abrupt throttle changes, excessive braking, incorrect body
movement or too much speed for the sharpness of the turn may cause the ATV to tip. If the ATV
begins to tip over to the outside while negotiating a turn, lean more to the inside. It may also be
necessary to gradually let off on the throttle and steer to the outside of the turn to avoid tipping
over.
Remember: Avoid higher speeds until you are thoroughly familiar with the operation of your ATV.

CLIMBING UPHILL

CAUTION!

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

 Never operate the ATV on hills too steep for the ATV or for your abilities. The ATV can

overturn more easily on extremely steep hills than on level surfaces or small hills.

 Always check the terrain carefully before you start up any hill. Never climb hills with

excessively slippery or loose surfaces.

49

 Shift your weight forward.
 Never open the throttle suddenly. The ATV could flip over backwards.
 Never go over the top of any hill at high speed. An obstacle, a sharp drop or another

vehicle or person could be on the other side of the hill.

 Never attempt to turn the ATV around on any hill until you have mastered the turning

technique as described in the Owner’s Manual on level ground. Be very careful when
turning on any hill.

 Avoid crossing the side of a steep hill if possible. When crossing the side of a hill, shift

your weight to the uphill side of the ATV.

Do not attempt to climb hills until you have mastered basic
maneuvers on flat ground. Always check the terrain
carefully before attempting any hill. In all cases avoid
inclines with slippery or loose surfaces or obstacles that
might cause you to lose control.
To climb a hill, you need traction, momentum and steady
throttle. For more traction and control for climbing steeper
and/or rougher slopes, select the “4WD” or 4WD-LOCK.
Travel fast enough to maintain momentum but not so fast
that you cannot react to changes in the terrain as you

climb.
It is important when climbing a hill to make sure that your weight is transferred forward on the ATV.
This can be accomplished by leaning forward and on steeper inclines, standing on the footboards
and leaning forward over the handlebars. Whenever possible, ride straight up hills.
Slow down when you reach the crest of the hill if you cannot see clearly what is on the other side
there could be another person, an obstacle or a sharp drop off. Use common sense and remember
that some hills are too steep for you to climb or descend.
If you are climbing a hill and you find that you have not properly judged your ability to make it to
the top, you should turn the ATV around while you still have forward motion and go down the hill.
If your ATV has stalled or stopped and you believe you can continue up the hill, restart carefully to
make sure you do not lift the front wheels which could cause you to lose control. If you are unable
to continue up the hill, dismount the ATV on the uphill side. Physically turn the ATV around and
then descend the hill.
If you start to roll backwards, DO NOT apply either brake abruptly. If you are in “2WD”, apply only
the front brake. When fully stopped, apply the rear brake as well and then shift to the park position.

If you are in “4WD” because all wheels are interconnected by the drive train, applying either brake

will brake all wheels, therefore avoid sudden application of either the front or rear brake as the
wheels on the uphill side could come off the ground. The ATV could easily tip over backwards. Apply
both the front and rear brakes gradually. When fully stopped, shift to the park position and
dismount the ATV immediately on the uphill side or to a side if pointed straight uphill. Turn the ATV
around and remount, following the procedure described in the Owner’s Manual.

50

WARNING!

Stalling, rolling backwards or improperly dismounting while climbing a hill could result in
ATV overturning. If you cannot control the ATV, dismount immediately on the uphill side.

RIDING DOWN HILL

WARNING!

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

 Always check the terrain carefully before you start down any hill.
 Never operate the ATV on hills too steep for the ATV or for your ability. The ATV can

overturn more easily on extremely steep hills than on level surfaces or small hills.

 Shift your weight backward and to the uphill side.
 Never go down a hill at high speed.
 Avoid going down a hill at an angle that would cause the ATV to lean sharply to one side.

Go straight down the hill where possible.

 Improper braking can cause the wheels on the hillside to come off the ground or cause

loss of traction. Apply brakes gradually. If in “2WD”, apply only the rear brake.

When riding your ATV downhill, shift your weight as far
to the rear and uphill side of the ATV as possible. Move
back on the seat and sit with your arms straight. Engine
compression will do most of the braking for you. For
maximum engine compression braking effect, select the

low gear position and change to “4WD” before

beginning to descend the hill.
Use caution while descending a hill with loose or
slippery surfaces. Braking ability and traction may be
adversely affected by these surfaces. Improper braking
may also cause a loss of traction.

When this ATV is in “4WD”, all wheels are interconnected by drive train. This means that applying

either the front brake or the rear brake will brake all wheels. When descending hills, using either
brake lever or the brake pedal will brake the wheels on the downhill side. Avoid sudden application
of either the front or rear brake because the wheels on the uphill side could come off the ground.
Apply both the front and rear brakes gradually.
Whenever possible, ride your ATV straight downhill. Avoid sharp angles, which could allow the ATV
to tip or roll over. Carefully choose your path and ride no faster than you will be able to react to
obstacles, which may appear.

51

CROSSING A SLOPE

WARNING!

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

 Always follow proper procedures as described in the Owner’s Manual.
 Avoid hills with excessively slippery or loose surfaces.
 Avoid crossing the side of a steep hill.
 Shift your weight to the uphill side of the ATV.
 Never attempt to turn the ATV around on any hill until you have mastered the turning

technique as described in the Owner’s Manual on level ground. Be very careful when

turning on any hill.

Traversing a sloping surface on your ATV requires you to
properly position your weight to maintain proper
balance. Be sure that you have learned the basic riding
skills on flat ground before attempting to cross a sloping
surface. Avoid slopes with slippery surfaces or rough
terrain that may upset your balance.
As you travel across a slope, lean your body in the uphill
direction. It may be necessary to correct the steering
when riding on loose surfaces by pointing the front
wheels slightly uphill. When riding on slopes, be sure
not to make sharp turns either up or down hill.
If your ATV does begin to tip over, gradually steer in the downhill direction if there are no obstacles
in your path. As you regain proper balance, gradually steer again in the direction you wish to travel.

CROSSING THROUGH SHALLOW WATER

WARNING!

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

The ATV can be used to cross slow moving, shallow water of up to maximum of 35 cm (14 in) in
depth. Before entering the water, choose your path carefully. Enter where there is no sharp drop off,
and avoid rocks or other obstacles, which may be slippery or upset the ATV. Drive slowly and
carefully.
Test your brakes after leaving the water. If necessary apply them several times to let the friction dry
out the linings. Do not continue to ride your ATV without verifying that you have regained proper
braking ability.

52

WARNING!

Wet brakes may have reduced stopping ability, which could cause loss of control.

After riding your ATV in water, be sure to drain the trapped water by removing the check hose at the
bottom of the air filter case, remove the v-belt case drain bolt and front storage compartment drain
plug to drain any water that may have accumulated.

NOTICE!

Un-drained water can cause damage or improper operation.

RIDING OVER ROUGH TERRAIN

WARNING!

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

Riding over rough terrain should be done with caution. Look out for obstacles, which could cause
damage to the ATV or could lead to an upset or accident. Be sure to keep your feet firmly mounted
on the footboards at all times. Avoid jumping the ATV as loss of control and damage to the ATV may
result.

SLIDING AND SKIDDING

WARNING!

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

 Learn to safety 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 cautions in order to

reduce the chance of skidding or sliding out of control.

Care should be used when riding on loose or slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could lead to an accident.
To reduce the tendency for the front wheels to slide in loose or slippery conditions, positioning your
weight over the front wheels will sometimes help.
If the rear wheels of your ATV start to slide sideways, control can usually be regained by steering in
direction of the slide. Applying the brakes or accelerating is not recommended until you have
corrected the slide.
With practice, over a period of time, skill at controlled sliding can be developed. The terrain should
be chosen carefully before attempting such maneuvers since both stability and control are reduced.
Bear in mind that sliding maneuvers should always be avoided on extremely slippery surfaces, such
as ice, since all control may be lost.

53

WHAT TO DO

 If your ATV doesn’t turn when you want it to:

Bring ATV to a stop and practice the turning maneuvers again. Be sure you are putting your
weight on the footboard to the outside of the turn. Position your weight over the front
wheels for better control

 If your ATV begins to tip while turning:

Lean more into the turn to regain balance. If necessary, gradually let off the throttle and /
or steer to the outside of the turn.

 If your ATV starts to slide sideways:

Steer in direction of the slide if you have the room. Applying the brakes or accelerating is
not recommended until you have corrected the slide.

 If your ATV can’t make it up a hill you are trying to climb:

Turn the ATV around if you still have forward speed. If not, stop, dismount on the uphill
side of the ATV and physically turn the ATV around. If the ATV starts to slip backwards, DO
NOT USE THE REAR BRAKE IF THE ATV IS IN “2WD”- The ATV may tip over on top of you.
Dismount the ATV on the uphill side.

 If your ATV is traversing a sloping surface:

Be sure to ride with your weight positioned towards the uphill side of the ATV to maintain
proper balance. If the ATV starts to tip, steer down the hill to regain balance. If you
discover that the ATV is going to tip over, dismount on the uphill side.

 If your ATV encounters shallow water:

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

54

PERIODIC MAINTENANCE

Periodic inspection, adjustment and lubrication will keep your vehicle in the safest and most
efficient condition possible. Safety is an obligation of the vehicle owner/operator.

WARNING!

Failure to properly maintain the vehicle or performing maintenance activities incorrectly
may increase your risk of injury or death during service or while using the vehicle. If you are
not familiar with vehicle service, have a dealer perform the service.

WARNING!

Turn off the engine when performing maintenance unless otherwise specified.

 A running engine has moving parts that can catch on body parts or clothing and electrical

parts that can cause shocks or fires.

 Running the engine while servicing can lead to eye injury, burns, fire or carbon monoxide

poisoning-possibly leading to death.

WARNING!

Brake discs, calipers, drums and linings can become very hot during use. To avoid possible
burns, let brake components cool before touching them.

The intervals given in the periodic maintenance charts should be considered as a general guide
under normal riding conditions. However, depending on the weather, terrain, geographical

location and individual use, the maintenance intervals may need to be shortened.

Have your ATV serviced and checked by an authorized dealer. Ensure the service book is stamped
and signed. Failure to do so could invalidate your warranty.
The maintenance schedule is based on months of use or kilometers traveled. Do the scheduled
maintenance based on which ever comes first.

CAUTION!

 Some maintenance items need more frequent service if you are riding in unusually wet,

sandy or muddy areas or at full throttle.

 Hydraulic brake service

 Regularly check and if necessary correct the brake fluid level.
 Every two years replace the internal components of the brake master cylinder and

calipers and change the brake fluid.

 Replace the brake hoses every four years and if cracked or damaged.

 Remove the carbon deposits in cylinder head, piston and exhaust system when power is

obviously lower than normal.

 Perform maintenance and check when continuous abnormal misfire, after-urn and

overheating occur.

57

CLEANING AND STORAGE

Cleaning

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

1. Before cleaning the ATV:

a. Block off the end of the exhaust pipe to prevent water entry. A plastic bag and strong rubber

band may be used.

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

2. If the engine case is excessively greasy, apply degreaser with a paintbrush. Do not apply

degreaser to wheel axles.

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

WARNING!

 Wet brakes may have reduced stopping ability, increasing the chance of an accident. Test

the brakes after washing. Apply the brakes several times at slow speeds to let friction dry
out the linings.

 Excessive water pressure may cause water seepage and deterioration of wheel bearing,

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

4. Once most of the dirt has been hosed off, wash all surfaces with warm water and mild,

detergent-type soap. An old toothbrush or bottlebrush is handy for hard to reach places.

5. Rinse the ATV off immediately with clean water and dry all surfaces with a chamois, clean

towel or soft absorbing cloth.

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

7. Automotive type wax may be applied to all painted and chrome plated surfaces. Avoid

combination cleaner-waxes. Many contain abrasives, which may mar the paint or protective
finish. When finished cleaning, start the engine and let it idle for several minutes.

Storage
Short-term

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

WARNING!

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

Long-term

Before storing your ATV for several months:

58

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

2. Turn the fuel cock lever to “OFF”.

1. Drain the carburetor float chamber by loosening the drain bolt; this will prevent fuel deposits

from building up. Pour the drained fuel into the fuel tank.

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

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

a. Remove the spark plug cap and spark plug.
b. Pour a teaspoonful of engine oil into the spark plug bore.
c. Install the spark plug cap onto the spark plug and then place the spark plug on the cylinder

head so that the electrodes are grounded.
d. Turn the engine over several times with the starter.
e. Remove the spark plug cap from the spark plug and then install the spark plug and the spark

plug cap.

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

5. Check and if necessary, correct the tire air pressure and then block up the ATV so that all of its

wheels are off the ground. Alternatively, turn the wheels a little every month in order to
prevent the tires from becoming degraded in one spot.

6. Cover the muffler outlet with a plastic bag to prevent moisture from entering it.

7. Remove the battery and fully charge it. Store it in a cool, dry place and charge it once a month.

Do not store the battery in an excessively cold or warm place less than 0℃ or more than 30℃.

8. Make necessary repairs before storing the ATV.

responsible for presenting your ATV to a Textron Specialized Vehicles' dealer as soon as a problem
exists. The warranty repair should be completed in a reasonable amount of time, not to exceed
thirty (30) days.

Emission System Warranty Statement:

As the ATV owner, you should also be aware that Textron Specialized Vehicles may deny you
warranty coverage if your vehicle or a part has failed due to abuse, neglect, improper maintenance
or unapproved modifications. If you have any questions regarding your warranty rights and
responsibilities or if an authorized Textron Specialized Vehicles dealer cannot repair your ATV or

65

honor your claim within a reasonable period of time, contact Textron Specialized Vehicles for
assistance at 1-800-448-7476. If you are not satisfied with the way in which a warranty claim is

Emissions Warranty Coverage:

A qualified repair shop or person of the owner's choosing may maintain, replace, or repair emission
control devices and systems with original or equivalent replacement parts. However, warranty, recall
and all other services paid for by TSV must be performed at an authorized TSV service center.

Textron Specialized Vehicles warrants to the owner of any 2016 and subsequent model year ATV
that the ATV is designed, built and equipped to conform at the time of sale with all applicable
emission standards and is free from defects in materials and workmanship which would cause it to
fail to conform with applicable requirements during the specified time and mileage limits.

This warranty begins on the date the ATV is delivered to the first purchaser other than an authorized
Textron Specialized Vehicles dealer, or the date it is first used as a demonstrator, lease, or company
ATV, whichever comes first and continues for the time and mileage listed below:

Your emission control system may include parts such as the carburetor or fuel injection system,
ignition system, catalytic converter, and engine computer. Also included may be hoses, belts,
connectors, and other emission related assemblies.

Where a warrantable condition exists, Textron Specialized Vehicles will repair your ATV at no cost to
you including diagnosis, parts and labor.

Time 30 months

Mileage 3100 miles (5,000 kilometers)

These warranties are given only to the owner of a 2016 and subsequent model year ATV distributed
by Textron Specialized Vehicles.

Emission System Warranty Statement:

To qualify for coverage under the defects warranty you should operate and maintain your ATV
according to the requirements of the warranty booklet, and the maintenance schedule in the
owner's manual. This schedule is designed to keep your ATV emission control systems functioning
properly by maintaining your ATV in peak operating condition. Textron Specialized Vehicles will not
deny a warranty claim solely because of lack of maintenance records. However, failures caused by

66

abuse or lack of required maintenance will not be covered by this warranty.

Textron Specialized Vehicles recommends that only parts supplied by Textron Specialized Vehicles or
equivalent parts be used to repair your ATV. Maintenance, replacement, or repair of emission
control devices and systems may be done by any ATV repair establishment or individual. Textron
Specialized Vehicles will only pay for warranty repairs performed at an authorized Textron
Specialized Vehicles ATV repair facility (except in an emergency situation). An emergency situation
exists when a Textron Specialized Vehicles dealership is not reasonably available, a warranted part is
not available within thirty (30) days, or when an authorized Textron Specialized Vehicles facility is
unable to complete a repair within thirty (30) days. In an emergency situation, the repair of
emission control devises or system may be done by any ATV qualified repair establishment or
individual, or by the owner, using any replacement part.

Textron Specialized Vehicles will reimburse you for those emergency repairs, including diagnosis,
covered by the Emissions Warranties. Parts reimbursement is at the manufacturer's suggested retail
price, and labor reimbursement is at a geographically-appropriate hourly labor rate for Textron
Specialized Vehicles recommended time allowance. For reimbursement, present the replacement
parts and a copy of the paid receipt to Textron Specialized Vehicles.

The use of replacement parts not equivalent to the original parts may impair the effectiveness of
your ATV emissions control systems. If such a replacement part is used in the maintenance or repair
of your ATV and an authorized Textron Specialized Vehicles dealer determines it is defective or
caused a failure of a warranted part, your claim for repair to bring your ATV into compliance with
applicable standards may be denied. If the part in question is not related to the reason your ATV
fails to meet the standards, your claim will not be denied.
