Q SAFETY INFORMATION

EAU10220

SCOOTERS ARE SINGLE TRACK VEHICLES. THEIR SAFE USE AND OPERATION ARE DEPENDENT UPON

THE USE OF PROPER RIDING TECHNIQUES AS WELL AS THE EXPERTISE OF THE OPERATOR. EVERY OP-

ERATOR SHOULD KNOW THE FOLLOWING REQUIREMENTS BEFORE

RIDING THIS SCOOTER. HE OR SHE SHOULD:

8 OBTAIN THOROUGH INSTRUC-

TIONS FROM A COMPETENT

SOURCE ON ALL ASPECTS OF

SCOOTER OPERATION.

8 OBSERVE THE WARNINGS AND

MAINTENANCE REQUIRE-

MENTS IN THE OWNER’S

MANUAL.

8 OBTAIN QUALIFIED TRAINING IN

SAFE AND PROPER RIDING

TECHNIQUES.

8 OBTAIN PROFESSIONAL TECH-

NICAL SERVICE AS INDICATED

BY THE OWNER’S MANUAL AND/

OR WHEN MADE NECESSARY

BY MECHANICAL CONDITIONS.

EAU10260

Safe riding

8 Always make pre-operation checks.

Careful checks may help prevent an accident.

8 This scooter is designed to carry

the operator and passenger.

8 The failure of motorists to detect

and recognize scooters in traffic is the predominating cause of automobile/scooter accidents. Many accidents have been caused by an automobile driver who did not see the scooter. Making yourself conspicuous appears to be very effective in reducing the chance of this type of accident.

Therefore:

9 Wear a brightly colored jacket. 9 Use extra caution when

approaching and passing through intersections, since intersections are the most likely places for scooter accidents to occur.

9 Ride where other motorists can

see you. Avoid riding in another motorist’s blind spot.

1-1

8 Many accidents involve inexperi-

enced operators. In fact, many operators who have been involved in accidents do not even have a current driver’s license. 9 Make sure that you are quali-

fied and that you only lend your scooter to other qualified operators.

9 Know your skills and limits.

Staying within your limits may help you to avoid an accident.

9 We recommend that you

practice riding your scooter where there is no traffic until you have become thoroughly familiar with the scooter and all

of its controls. Many accidents have been caused by error of the scooter operator. A typical error made by the operator is veering wide on a turn due to EXCESSIVE SPEED or undercornering (insufficient lean angle for the speed). 9 Always obey the speed limit

and never travel faster than

warranted by road and traffic

conditions.

Q SAFETY INFORMATION

9 Always signal before turning or

changing lanes. Make sure that other motorists can see you.

8 The posture of the operator and

passenger is important for proper control. 9 The operator should keep both

hands on the handlebar and both feet on the footboard during operation to maintain control of the scooter.

9 The passenger should always

hold onto the operator, the seat strap or grab bar, if equipped, with both hands and keep both feet on the passenger footrests.

9 Never carry a passenger unless

he or she can firmly place both feet on the passenger footrests.

8 Never ride under the influence of

alcohol or other drugs. This scooter is designed for on-road use only. It is not suitable for offroad use.

Protective apparel

The majority of fatalities from scooter accidents are the result of head injuries. The use of a safety helmet is the single most critical factor in the prevention or reduction of head injuries.

8 Always wear an approved helmet. 8 Wear a face shield or goggles. Wind

in your unprotected eyes could contribute to an impairment of vision which could delay seeing a hazard.

8 The use of a jacket, substantial

shoes, trousers, gloves, etc., is effective in preventing or reducing abrasions or lacerations.

8 Never wear loose-fitting clothes,

otherwise they could catch on the control levers or wheels and cause injury or an accident.

8 Never touch the engine or exhaust

system during or after operation. They become very hot and can cause burns. Always wear protective clothing that covers your legs, ankles, and feet.

8 Passengers should also observe

the above precautions.

Modifications

Modifications made to this scooter not approved by Yamaha, or the removal of original equipment, may render the scooter unsafe for use and may cause severe personal injury. Modifications may also make your scooter illegal to use.

Loading and accessories

Adding accessories or cargo to your scooter can adversely affect stability and handling if the weight distribution of the scooter is changed. To avoid the possibility of an accident, use extreme caution when adding cargo or accessories to your scooter. Use extra care when riding a scooter that has added cargo or accessories. Here are some general guidelines to follow if loading cargo or adding accessories to your scooter:

1-2

Q SAFETY INFORMATION

Loading The total weight of the operator, passenger, accessories and cargo must not exceed the maximum load limit of 170 kg

(374 lb). When loading within this weight limit, keep the following in mind:

8 Cargo and accessory weight should

be kept as low and close to the

scooter as possible. Make sure to distribute the weight as evenly as possible on both sides of the scooter to minimize imbalance or instability.

8 Shifting weights can create a sud-

den imbalance. Make sure that accessories and cargo are securely attached to the scooter before riding. Check accessory mounts and cargo restraints frequently.

8 Never attach any large or heavy

items to the handlebar, front fork, or front fender. Such items can create unstable handling or a slow steering response.

Accessories Genuine Yamaha accessories have been specifically designed for use on this scooter. Since Yamaha cannot test all other accessories that may be available, you must personally be responsible for the proper selection, installation and use of non-Yamaha accessories. Use extreme caution when selecting and installing any accessories. Keep the following guidelines in mind, as well as those provided under “Loading” when mounting accessories.

8 Never install accessories or carry

cargo that would impair the performance of your scooter. Carefully inspect the accessory before using it to make sure that it does not in any way reduce ground clearance or cornering clearance, limit suspension travel, steering travel or control operation, or obscure lights or reflectors. 9 Accessories fitted to the

handlebar or the front fork area can create instability due to improper weight distribution or aerodynamic changes. If

accessories are added to the

handlebar or front fork area,

they must be as lightweight as

possible and should be kept to

a minimum. 9 Bulky or large accessories may

seriously affect the stability of

the scooter due to aerodynamic

effects. Wind may attempt to

lift the scooter, or the scooter

may become unstable in cross

winds. These accessories may

also cause instability when

passing or being passed by

large vehicles. 9 Certain accessories can

displace the operator from his

or her normal riding position.

This improper position limits

the freedom of movement of

the operator and may limit

control ability, therefore, such

accessories are not recom-

mended.

8 Use caution when adding electrical

accessories. If electrical accessories exceed the capacity of the scooter’s electrical system an elec-

1-3

Q SAFETY INFORMATION

tric failure could result, which could cause a dangerous loss of lights or engine power.

Gasoline and exhaust gas

8 GASOLINE IS HIGHLY FLAM-

MABLE: 9 Always turn the engine off

when refueling.

9 Take care not to spill any

gasoline on the engine or exhaust system when refueling.

9 Never refuel while smoking or

in the vicinity of an open flame.

8 Never start the engine or let it run

for any length of time in a closed area. The exhaust fumes are poisonous and may cause loss of consciousness and death within a short time. Always operate your scooter in an area that has adequate ventilation.

8 Always turn the engine off before

leaving the scooter unattended and remove the key from the main switch. When parking the scooter, note the following: 9 The engine and exhaust

system may be hot, therefore, park the scooter in a place where pedestrians or children are not likely to touch these hot areas.

9 Do not park the scooter on a

slope or soft ground, otherwise it may fall over.

9 Do not park the scooter near a

flammable source (e.g., a kerosene heater, or near an open flame), otherwise it could catch fire.

8 If you should swallow any gasoline,

inhale a lot of gasoline vapor, or allow gasoline to get into your eyes, see your doctor immediately. If any gasoline spills on your skin or clothing, immediately wash the affected area with soap and water and change your clothes.

Q SAFETY INFORMATION

8 Braking can be extremely difficult

on a wet road. Avoid hard braking, because the scooter could slide.

Apply the brakes slowly when stopping on a wet surface.

8 Slow down as you approach a cor-

ner or turn. Once you have completed a turn, accelerate slowly.

8 Be careful when passing parked

cars. A driver might not see you and open a door in your path.

8 Railroad crossings, streetcar rails,

iron plates on road construction sites, and manhole covers become extremely slippery when wet. Slow down and cross them with caution. Keep the scooter upright, otherwise it could slide out from under you.

8 The brake pads could get wet when

you wash the scooter. After washing the scooter, check the brakes before riding.

8 Always wear a helmet, gloves, trou-

sers (tapered around the cuff and ankle so they do not flap), and a bright colored jacket.

8 Do not carry too much luggage on

the scooter. An overloaded scooter is unstable.
