Be a Responsible OwnerAs the vehicle’s owner, you are res-ponsible for the safe and proper ope-ration of your scooter.Scooters are single-track vehicles.Their safe use and operation aredependent upon the use of properriding techniques as well as theexpertise of the operator. Every ope-rator should know the following requi-rements before riding this scooter.He or she should:

� Obtain thorough instructionsfrom a competent source on allaspects of scooter operation.

� Observe the warnings and main-tenance requirements in thisOwner’s Manual.

� Obtain qualified training in safeand proper riding techniques.

� Obtain professional technicalservice as indicated in thisOwner’s Manual and/or whenmade necessary by mechanicalconditions.

Safe RidingPerform the pre-operation checkseach time you use the vehicle to

make sure it is in safe operating con-dition. Failure to inspect or maintainthe vehicle properly increases thepossibility of an accident or equip-ment damage. See page 4-1 for a listof pre-operation checks.

� This scooter is designed to carrythe operator and a passenger.

TIPAlthough this scooter is designed tocarry a passenger, always complywith the local regulations.

� The failure of motorists to detectand recognize scooters in trafficis the predominating cause ofautomobile/scooter accidents.Many accidents have been cau-sed by an automobile driver whodid not see the scooter. Makingyourself conspicuous appears tobe very effective in reducing thechance of this type of accident.Therefore:• Wear a brightly colored jacket.• Use extra caution when you

are approaching and passingthrough intersections, since

intersections are the mostlikely places for scooter acci-dents to occur.

• Ride where other motorists cansee you. Avoid riding in anot-her motorist’s blind spot.

� Many accidents involve inexpe-rienced operators. In fact, manyoperators who have been invol-ved in accidents do not evenhave a current driver’s license.• Make sure that you are quali-

fied and that you only lend yourscooter to other qualified ope-rators.

• Know your skills and limits.Staying within your limits mayhelp you to avoid an accident.

• We recommend that you prac-tice riding your scooter wherethere is no traffic until you havebecome thoroughly familiarwith the scooter and all of itscontrols.

� Many accidents have been cau-sed by error of the scooter ope-rator. A typical error made by theoperator is veering wide on a turndue to excessive speed or under-

1

SAFETY INFORMATION

49D-F819D-E0 18/12/08 16:56 Página 8

cornering (insufficient lean anglefor the speed).• Always obey the speed limit

and never travel faster thanwarranted by road and trafficconditions.

• Always signal before turning orchanging lanes. Make sure thatother motorists can see you.

� The posture of the operator andpassenger is important for propercontrol.• The operator should keep both

hands on the handlebar andboth feet on the operator foo-trests during operation tomaintain control of the scooter.

• The passenger should alwayshold onto the operator, the seatstrap or grab bar, if equipped,with both hands and keep bothfeet on the passenger foo-trests. Never carry a passengerunless he or she can firmly pla-ce both feet on the passengerfootrests.

� Never ride under the influence ofalcohol or other drugs.

� This scooter is designed for on-road use only. It is not suitable foroff-road use.

Protective apparelThe majority of fatalities from scooteraccidents are the result of head inju-ries. The use of a safety helmet is thesingle most critical factor in the pre-vention or reduction of head injuries.

� Always wear an approved hel-met.

� Wear a face shield or goggles.Wind in your unprotected eyescould contribute to an impair-ment of vision that could delayseeing a hazard.

� The use of a jacket, substantialshoes, trousers, gloves, etc., iseffective in preventing or redu-cing abrasions or lacerations.

� Never wear loose-fitting clothes,otherwise they could catch onthe control levers or wheels andcause injury or an accident.

� Always wear protective clothingthat covers your legs, ankles, andfeet. The engine or exhaust sys-tem become very hot during or

after operation and can causeburns.

� A passenger should also observethe above precautions.

Avoid Carbon Monoxide PoisoningAll engine exhaust contains carbonmonoxide, a deadly gas. Breathingcarbon monoxide can cause heada-ches, dizziness, drowsiness, nausea,confusion, and eventually death.Carbon Monoxide is a colorless,odorless, tasteless gas which may bepresent even if you do not see orsmell any engine exhaust. Deadlylevels of carbon monoxide can collectrapidly and you can quickly be over-come and unable to save yourself.Also, deadly levels of carbon monoxi-de can linger for hours or days inenclosed or poorly ventilated areas. Ifyou experience any symptoms of car-bon monoxide poisoning, leave thearea immediately, get fresh air, andSEEK MEDICAL TREATMENT.

� Do not run engine indoors. Evenif you try to ventilate engineexhaust with fans or open win-dows and doors, carbon monoxi-de can rapidly reach dangerouslevels.

� Do not run engine in poorly venti-lated or partially enclosed areassuch as barns, garages, or car-ports.

� Do not run engine outdoors whe-re engine exhaust can be drawninto a building through openingssuch as windows and doors.

LoadingAdding accessories or cargo to yourscooter can adversely affect stabilityand handling if the weight distributionof the scooter is changed. To avoidthe possibility of an accident, useextreme caution when adding cargoor accessories to your scooter. Useextra care when riding a scooter thathas added cargo or accessories.Here, along with the informationabout accessories below, are somegeneral guidelines to follow if loadingcargo to your scooter:

The total weight of the operator, pas-senger, accessories and cargo mustnot exceed the maximum load limit.Operation of an overloaded vehiclecould cause an accident.

When loading within this weight limit,keep the following in mind:

� Cargo and accessory weightshould be kept as low and closeto the scooter as possible. Secu-rely pack your heaviest items asclose to the center of the vehicleas possible and make sure to dis-tribute the weight as evenly aspossible on both sides of thescooter to minimize imbalance orinstability.

� Shifting weights can create asudden imbalance. Make surethat accessories and cargo aresecurely attached to the scooterbefore riding. Check accessorymounts and cargo restraints fre-quently.

� Properly adjust the suspensionfor your load (suspension-adjus-table models only), and check thecondition and pressure of yourtires.

� Never attach any large or heavyitems to the handlebar, front fork,or front fender. Such items cancreate unstable handling or aslow steering response.

� This vehicle is not designed topull a trailer or to be attachedto a sidecar.

Genuine Yamaha AccessoriesChoosing accessories for your vehicleis an important decision. GenuineYamaha accessories, which are avai-lable only from a Yamaha dealer, havebeen designed, tested, and approvedby Yamaha for use on your vehicle.Many companies with no connectionto Yamaha manufacture parts andaccessories or offer other modifica-tions for Yamaha vehicles. Yamaha isnot in a position to test the productsthat these aftermarket companiesproduce. Therefore, Yamaha can neit-her endorse nor recommend the useof accessories not sold by Yamaha or

modifications not specifically recom-mended by Yamaha, even if sold andinstalled by a Yamaha dealer.Aftermarket Parts, Accessories,and ModificationsWhile you may find aftermarket pro-ducts similar in design and quality togenuine Yamaha accessories, recog-nize that some aftermarket accesso-ries or modifications are not suitablebecause of potential safety hazards toyou or others. Installing aftermarketproducts or having other modifica-tions performed to your vehicle thatchange any of the vehicle’s design oroperation characteristics can put youand others at greater risk of seriousinjury or death. You are responsiblefor injuries related to changes in thevehicle.Keep the following guidelines in mind,as well as those provided under “Loa-ding” when mounting accessories.

� Never install accessories or carrycargo that would impair the per-formance of your scooter. Care-fully inspect the accessory befo-re using it to make sure that itdoes not in any way reduce

ground clearance or corneringclearance, limit suspension tra-vel, steering travel or control ope-ration, or obscure lights or reflec-tors.• Accessories fitted to the hand-

lebar or the front fork area cancreate instability due to impro-per weight distribution oraerodynamic changes. Ifaccessories are added to thehandlebar or front fork area,they must be as lightweight aspossible and should be kept toa minimum.

• Bulky or large accessories mayseriously affect the stability ofthe scooter due to aerodyna-mic effects. Wind may attemptto lift the scooter, or the scoo-ter may become unstable incross winds. These accesso-ries may also cause instabilitywhen passing or being passedby large vehicles.

• Certain accessories can dis-place the operator from his orher normal riding position. Thisimproper position limits the fre-

edom of movement of the ope-rator and may limit control abi-lity, therefore, such accesso-ries are not recommended.

� Use caution when adding electri-cal accessories. If electricalaccessories exceed the capacityof the scooter’s electrical system,an electric failure could result,which could cause a dangerousloss of lights or engine power.

Aftermarket Tires and RimsThe tires and rims that came with yourscooter were designed to match theperformance capabilities and to pro-vide the best combination of hand-ling, braking, and comfort. Other tires,rims, sizes, and combinations maynot be appropriate. Refer to page 6-11 for tire specifications and moreinformation on replacing your tires.

EAU10372

Further safe-riding points� Be sure to signal clearly when

making turns.� Braking can be extremely difficult

on a wet road. Avoid hard bra-king, because the scooter couldslide. Apply the brakes slowlywhen stopping on a wet surface.

� Slow down as you approach acorner or turn. Once you havecompleted a turn, accelerateslowly.

� Be careful when passing parkedcars. A driver might not see youand open a door in your path.

� Railroad crossings, streetcarrails, iron plates on road cons-truction sites, and manholecovers become extremely slip-pery when wet. Slow down andcross them with caution. Keepthe scooter upright, otherwise itcould slide out from under you.

� The brake pads could get wetwhen you wash the scooter. Afterwashing the scooter, check thebrakes before riding.

� Always wear a helmet, gloves,trousers (tapered around the cuffand ankle so they do not flap),and a bright colored jacket.

� Do not carry too much luggageon the scooter. An overloadedscooter is unstable. Use a strongcord to secure any luggage to thecarrier (if equipped). A loose loadwill affect the stability of the sco-oter and could divert your atten-tion from the road. (See page 1-1).

Checking the spark plugThe spark plug is an important enginecomponent, which should be chec-ked periodically, preferably by aYamaha dealer. Since heat and depo-sits will cause any spark plug toslowly erode, it should be removedand checked in accordance with theperiodic maintenance and lubricationchart. In addition, the condition of thespark plug can reveal the condition ofthe engine.The porcelain insulator around thecenter electrode of the spark plugshould be a medium-to-light tan (theideal color when the vehicle is riddennormally). If the spark plug shows adistinctly different color, the enginecould be operating improperly. Do notattempt to diagnose such problemsyourself. Instead, have a Yamahadealer check the vehicle.If the spark plug shows signs of elec-trode erosion and excessive carbonor other deposits, it should be repla-ced.

Before installing a spark plug, thespark plug gap should be measuredwith a wire thickness gauge and, ifnecessary, adjusted to specification.

1. Spark plug gap

Clean the surface of the spark pluggasket and its mating surface, andthen wipe off any grime from thespark plug threads.

� The wheel should be balancedwhenever either the tire or wheelhas been changed or replaced.An unbalanced wheel can resultin poor performance, adversehandling characteristics, and ashortened tire life.

� Ride at moderate speeds afterchanging a tire since the tire sur-face must first be “broken in” forit to develop its optimal characte-ristics.

Checking the brake fluidlevel

1. Minimum level mark

Insufficient brake fluid may allow airto enter the brake system, possiblycausing it to become ineffective.Before riding, check that the brakefluid is above the minimum level markand replenish if necessary. A low bra-ke fluid level may indicate worn brakepads and/or brake system leakage. Ifthe brake fluid level is low, be sure tocheck the brake pads for wear andthe brake system for leakage.

Observe these precautions:� When checking the fluid level,

make sure that the top of themaster cylinder is level by turningthe handlebars.

� Use only the recommended qua-lity brake fluid, otherwise the rub-ber seals may deteriorate, cau-sing leakage and poor brakingperformance.

� Refill with the same type of brakefluid. Mixing fluids may result in aharmful chemical reaction andlead to poor braking performan-ce.

� Be careful that water does notenter the master cylinder whenrefilling. Water will significantlylower the boiling point of the fluidand may result in vapor lock.

� Brake fluid may deteriorate pain-ted surfaces or plastic parts.Always clean up spilled fluidimmediately.

� As the brake pads wear, it is nor-mal for the brake fluid level togradually go down. However, ifthe brake fluid level goes downsuddenly, have a Yamaha dealercheck the cause.

� Do not use high-pressure was-hers or steam-jet cleaners sin-ce they cause water seepageand deterioration in the follo-wing areas: seals (of wheel andswingarm bearings, fork andbrakes), electric components(couplers, connectors, instru-ments, switches and lights),breather hoses and vents.

� For scooters equipped with awindshield: Do not use strongcleaners or hard sponges asthey will cause dulling or scrat-ching. Some cleaning com-pounds for plastic may leavescratches on the windshield.Test the product on a small hid-den part of the windshield tomake sure that it does not lea-ve any marks. If the windshieldis scratched, use a qualityplastic polishing compoundafter washing.

After normal use1. Remove dirt with warm water, a

mild detergent, and a soft, cleansponge, and then rinse tho-roughly with clean water. Use atoothbrush or bottlebrush forhard-to-reach areas. Stubborndirt and insects will come offmore easily if the area is coveredwith a wet cloth for a few minutesbefore cleaning.

After riding in the rain, near the sea oron salt-sprayed roads

1. Since sea salt or salt sprayed onthe roads during winter are extre-mely corrosive in combinationwith water, carry out the followingsteps after each ride in the rain,near the sea or on salt-sprayedroads.

TIPSalt sprayed on roads in the wintermay remain well into spring.

1. Clean the scooter with cold waterand a mild detergent after theengine has cooled down. NOTI-CE: Do not use warm water

since it increases the corrosiveaction of the salt. [ECA10791]

2. Apply a corrosion protectionspray on all metal, includingchrome- and nickel-plated, surfa-ces to prevent corrosion.
