e majority of fatalities from scootercidents are the result of head inju-s. The use of a safety helmet is thegle most critical factor in the pre-tion or reduction of head injuries.Always wear an approved helmet.Wear a face shield or goggles.Wind in your unprotected eyescould contribute to an impairmentof vision that could delay seeing ahazard.The use of a jacket, substantialshoes, trousers, gloves, etc., is ef-fective in preventing or reducingabrasions or lacerations.Never wear loose-fitting clothes,otherwise they could catch on thecontrol levers or wheels and causeinjury or an accident.Always wear protective clothingthat covers your legs, ankles, andfeet. The engine or exhaust sys-tem become very hot during or af-ter operation and can causeburns.A passenger should also observethe above precautions.


2-2

Many accidents involve inexperi-enced operators. In fact, many op-erators who have been involved inaccidents do not even have a cur-rent driver’s license.• Make sure that you are qualified

and that you only lend yourscooter to other qualified opera-tors.

• 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 familiar withthe scooter and all of its con-trols.

Many accidents have beencaused by error of the scooter op-erator. A typical error made by theoperator is veering wide on a turndue to excessive speed or under-cornering (insufficient lean anglefor the speed).• Always obey the speed limit and

never travel faster than warrant-ed by road and traffic condi-tions.

• 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 foot-rests during operation to main-tain 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 footrests.Never carry a passenger unlesshe or she can firmly place bothfeet on the passenger footrests.

oid Carbon Monoxide Poisoning

l engine exhaust contains carbononoxide, a deadly gas. Breathingrbon monoxide can cause head-hes, dizziness, drowsiness, nausea,nfusion, and eventually death.rbon Monoxide is a colorless, odor-s, tasteless gas which may be

esent even if you do not see or smelly engine exhaust. Deadly levels ofrbon monoxide can collect rapidlyd you can quickly be overcome andable to save yourself. Also, deadlyels of carbon monoxide can linger

r hours or days in enclosed or poorlyntilated areas. If you experience anymptoms of carbon monoxide poi-ning, leave the area immediately, getsh air, and SEEK MEDICAL TREAT-ENT.

Do not run engine indoors. Even ifyou try to ventilate engine exhaustwith fans or open windows anddoors, carbon monoxide can rap-idly reach dangerous levels.Do not run engine in poorly venti-lated or partially enclosed areassuch as barns, garages, or car-ports.

Do not run engine outdoors whereengine exhaust can be drawn intoa building through openings suchas windows and doors.

Loading

Adding accessories or cargo to yourscooter can adversely affect stabilityand handling if the weight distributionof the scooter is changed. To avoid thepossibility of an accident, use extremecaution when adding cargo or acces-sories to your scooter. Use extra carewhen riding a scooter that has addedcargo or accessories. Here, along withthe information about accessories be-low, are some general guidelines to fol-low if loading cargo to your scooter:The total weight of the operator, pas-senger, accessories and cargo mustnot exceed the maximum load limit.Operation of an overloaded vehicle

could cause an accident.

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

Maximum load:153 kg (337 lb)

• Bulky or large accessories mayseriously affect the stability ofthe scooter due to aerodynamiceffects. Wind may attempt to liftthe scooter, or the scooter maybecome unstable in crosswinds. These accessories mayalso cause instability whenpassing or being passed bylarge vehicles.

• Certain accessories can dis-place the operator from his orher normal riding position. Thisimproper position limits thefreedom of movement of theoperator and may limit controlability, therefore, such accesso-ries are not recommended.

Use caution when adding electri-cal accessories. If electrical ac-cessories exceed the capacity ofthe scooter’s electrical system, anelectric failure could result, whichcould cause a dangerous loss oflights or engine power.

WARNING

EWA10301

Avoid braking hard or suddenly

(especially when leaning over to

one side), otherwise the scooter

may skid or overturn.

Railroad crossings, streetcar

rails, iron plates on road con-

struction sites, and manhole

covers become extremely slip-

pery when wet. Therefore, slow

down when approaching such

areas and cross them with cau-

tion.

Keep in mind that braking on a

wet road is much more difficult.

Ride slowly down a hill, as brak-

ing downhill can be very diffi-

cult.

Use only the recommended quali-ty brake fluid, otherwise the rub-ber seals may deteriorate, causingleakage and poor braking perfor-mance.

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

Be careful that water does not en-ter the master cylinder when refill-ing. Water will significantly lowerthe boiling point of the fluid andmay result in vapor lock.

Brake fluid may deteriorate paint-ed surfaces or plastic parts. Al-ways 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.

TroubleshootingAlthough Yamaha vehicles receive athorough inspection before shipmentfrom the factory, trouble may occurduring operation. Any problem in thefuel, compression, or ignition systems,for example, can cause poor startingand loss of power.The following troubleshooting chartsrepresent quick and easy proceduresfor checking these vital systems your-self. However, should your vehicle re-quire any repair, take it to a Yamahadealer, whose skilled technicians havethe necessary tools, experience, andknow-how to service the vehicle prop-erly.Use only genuine Yamaha replace-ment parts. Imitation parts may looklike Yamaha parts, but they are ofteninferior, have a shorter service life andcan lead to expensive repair bills.

Fre-quent and proper care does not onlycomply with the terms of the warranty,but it will also keep your scooter look-ing good, extend its life and optimizeits performance.

Before cleaning

1. Cover the muffler outlet with aplastic bag after the engine hascooled down.

2. Make sure that all caps and cov-ers as well as all electrical cou-plers and connectors, includingthe spark plug cap, are tightly in-stalled.

off any detergent residue using

plenty of water, as it is harmful

to plastic parts.

Do not use any harsh chemical

products on plastic parts. Be

sure to avoid using cloths or

sponges which have been in

contact with strong or abrasive

cleaning products, solvent or

thinner, fuel (gasoline), rust re-

movers or inhibitors, brake fluid,

antifreeze or electrolyte.

Do not use high-pressure wash-

ers or steam-jet cleaners since

they cause water seepage and

deterioration in the following ar-

eas: seals (of wheel and swing-

arm bearings, fork and brakes),

electric components (couplers,

connectors, instruments,

switches and lights), breather

hoses and vents.

For scooters equipped with a

windshield: Do not use strong

cleaners or hard sponges as

they will cause dulling or

scratching. Some cleaning

compounds for plastic may

leave scratches on the wind-

shield. Test the product on a

small hidden part of the wind-

shield to make sure that it does

not leave any marks. If the wind-

shield is scratched, use a quality

plastic polishing compound af-

ter washing.

After normal useRemove dirt with warm water, a milddetergent, and a soft, clean sponge,and then rinse thoroughly with cleanwater. Use a toothbrush or bottlebrushfor hard-to-reach areas. Stubborn dirtand insects will come off more easily ifthe area is covered with a wet cloth fora few minutes before cleaning.

After riding in the rain or near the seaSince sea salt is extremely corrosivecarry out the following steps after eachride in the rain or near the sea.
