SAFETY INFORMATION

EAU50655

Be a Responsible Owner

As the vehicle’s owner, you are respon-

sible for the safe and proper operation

of your scooter.

Scooters are single-track vehicles.

Their safe use and operation are de-

pendent upon the use of proper riding

techniques as well as the expertise of

the operator. Every operator should

know the following requirements before

riding this scooter.

He or she should:

Obtain thorough instructions from

a competent source on all aspects

of scooter operation.

Observe the warnings and mainte-

nance requirements in this Own-

er’s Manual.

Obtain qualified training in safe

and proper riding techniques.

Obtain professional technical ser-

vice as indicated in this Owner’s

Manual and/or when made neces-

sary by mechanical conditions.

Never operate a scooter without

proper training or instruction. Take

a training course. Beginners

should receive training from a cer-

tified instructor. Contact an autho-

rized scooter dealer to find out

about the training courses nearest

you.

Safe Riding

Perform the pre-operation checks each

time you use the vehicle to make sure it

is in safe operating condition. Failure to

inspect or maintain the vehicle properly

increases the possibility of an accident

or equipment damage. See page 5-1

for a list of pre-operation checks.

This scooter is designed to carry

the operator only. No passengers.

The failure of motorists to detect

and recognize scooters in traffic is

the predominating cause of auto-

mobile/scooter accidents. Many

accidents have been caused by an

automobile driver who did not see

the scooter. Making yourself con-

spicuous appears to be very effec-

tive in reducing the chance of this

type of accident.

Therefore:

• Wear a brightly colored jacket.

• Use extra caution when you are

approaching and passing

through intersections, since in-

tersections are the most likely

places for scooter accidents to

occur.

• Ride where other motorists can

see you. Avoid riding in another

motorist’s blind spot.

• Never maintain a scooter with-

out proper knowledge. Contact

an authorized scooter dealer to

inform you on basic scooter

maintenance. Certain mainte-

nance can only be carried out by

certified staff.

Many accidents involve inexperi-

enced operators. In fact, many op-

erators who have been involved in

accidents do not even have a cur-

rent driver’s license.

• Make sure that you are qualified

and that you only lend your

scooter to other qualified opera-

tors.

• Know your skills and limits.

Staying within your limits may

help you to avoid an accident.

• We recommend that you prac-

1CB-9-EA.book 1 ページ２０１２年４月１１日　水曜日　午前９時３４分

SAFETY INFORMATION

1

tice riding your scooter where

there is no traffic until you have

become thoroughly familiar with

the scooter and all of its con-

trols.

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 ex-

cessive speed or undercornering

(insufficient lean angle for the

speed).

• Always obey the speed limit and

never travel faster than warrant-

ed by road and traffic conditions.

• Always signal before turning or

changing lanes. Make sure that

other motorists can see you.

The posture of the operator is im-

portant for proper control. The op-

erator should keep both hands on

the handlebar and both feet on the

operator footrests during operation

to maintain control of the scooter.

Do not place magnets or objects

with a strong magnetic force near

the accelerator grip. In addition, do

not place objects susceptible to

magnetic forces (i.e., credit cards,

watches, etc.) close to the acceler-

ator grip.

Never ride under the influence of

alcohol or other drugs.

This scooter is designed for

on-road use only. It is not suitable

for off-road use.

Avoid submerged roads

Do not ride on flooded roads. Water

could cause power unit failure, electric

leakage, and/or short-circuiting.

Protective Apparel

The majority of fatalities from scooter

accidents are the result of head inju-

ries. The use of a safety helmet is the

single most critical factor in the preven-

tion or reduction of head injuries.

Always wear an approved helmet.

Wear a face shield or goggles.

Wind in your unprotected eyes

could contribute to an impairment

of vision that could delay seeing a

hazard.

The use of a jacket, substantial

shoes, trousers, gloves, etc., is ef-

fective in preventing or reducing

abrasions or lacerations.

Never wear loose-fitting clothes,

otherwise they could catch on the

control levers or wheels and cause

injury or an accident.

Always wear protective clothing

that covers your legs, ankles, and

feet. The power unit become hot

during or after operation and can

cause burns.

Loading

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 accesso-

ries to your scooter. Use extra care

when riding a scooter that has added

cargo or accessories. Here, along with

the information about accessories be-

low, are some general guidelines to fol-

low if loading cargo to your scooter:

The total weight of the operator, acces-

sories and cargo must not exceed the

maximum load limit. Operation of an

overloaded vehicle could cause an

accident.

1CB-9-EA.book 2 ページ２０１２年４月１１日　水曜日　午前９時３４分

1-3

SAFETY INFORMATION

When loading within this weight limit,

keep the following in mind:

Cargo and accessory weight

should be kept as low and close to

the scooter as possible. Securely

pack your heaviest items as close

to the center of the vehicle as pos-

sible and make sure to distribute

the weight as evenly as possible

on both sides of the scooter to min-

imize imbalance or instability.

Shifting weights can create a sud-

den imbalance. Make sure that ac-

cessories and cargo are securely

attached to the scooter before

riding. Check accessory mounts

and cargo restraints frequently.

• Properly adjust the suspension

for your load (suspension-ad-

justable models only), and

check the condition and pres-

sure of your tires.

• 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.

This vehicle is not designed to

pull a trailer or to be attached to

a sidecar.

Genuine Yamaha Accessories

Choosing accessories for your vehicle

is an important decision. Genuine

Yamaha accessories, which are avail-

able only from a Yamaha dealer, have

been designed, tested, and approved

by Yamaha for use on your vehicle.

Many companies with no connection to

Yamaha manufacture parts and acces-

sories or offer other modifications for

Yamaha vehicles. Yamaha is not in a

position to test the products that these

aftermarket companies produce.

Therefore, Yamaha can neither en-

dorse nor recommend the use of ac-

cessories not sold by Yamaha or

modifications not specifically recom-

mended by Yamaha, even if sold and

installed by a Yamaha dealer.

Aftermarket Parts, Accessories,

and Modifications

While you may find aftermarket prod-

ucts similar in design and quality to

genuine Yamaha accessories, recog-

nize that some aftermarket accessories

or modifications are not suitable be-

cause of potential safety hazards to you

or others. Installing aftermarket prod-

ucts or having other modifications per-

formed to your vehicle that change any

of the vehicle’s design or operation

characteristics can put you and others

at greater risk of serious injury or death.

You are responsible for injuries related

to changes in the vehicle.

Keep the following guidelines in mind,

as well as those provided under “Load-

ing” when mounting accessories.

Never install accessories or carry

cargo that would impair the perfor-

mance 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 sus-

pension travel, steering travel or

control operation, or obscure lights

or reflectors.

• Accessories fitted to the handle-

bar or the front fork area can

create instability due to improper

weight distribution or aerody-

namic 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.

• 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.

• Certain accessories can dis-

place the operator from his or

her normal riding position. This

improper position limits the free-

dom of movement of the opera-

tor and may limit control ability,

therefore, such accessories are

not recommended.

Use caution when adding electri-

cal accessories. If electrical acces-

sories exceed the capacity of the

scooter’s electrical system, an

electric failure could result, which

could cause a dangerous loss of

lights or motor power.

Aftermarket Tires and Rims

The tires and rims that came with your

scooter were designed to match the

performance capabilities and to provide

the best combination of handling, brak-

ing, and comfort. Other tires, rims, siz-

es, and combinations may not be

appropriate. Refer to page 8-5 for tire

specifications and more information on

replacing your tires.

Transporting the Scooter

Be sure to observe following instruc-

tions before transporting the scooter in

another vehicle.

Remove all loose items from the

scooter.

Point the front wheel straight

ahead on the trailer or in the truck

bed, and choke it in a rail to pre-

vent movement.

Secure the scooter with tie-downs

or suitable straps that are attached

to solid parts of the scooter, such

as the frame or upper front fork tri-

ple clamp (and not, for example, to

rubber-mounted handlebars or

turn signals, or parts that could

break). Choose the location for the

straps carefully so the straps will

not rub against painted surfaces

during transport.

The suspension should be com-

pressed somewhat by the

tie-downs, if possible, so that the

scooter will not bounce excessive-

ly during transport.

SAFETY INFORMATION

EAUT2031

Further safe-riding points

Make sure to signal clearly when

making turns.

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.

Slow down as you approach a cor-

ner or turn. Once you have com-

pleted a turn, accelerate slowly.

Be careful when passing parked

cars. A driver might not see you

and open a door in your path.

Railroad crossings, streetcar rails,

iron plates on road construction

sites, and manhole covers be-

come extremely slippery when

wet. Slow down and cross them

with caution. Keep the scooter up-

right, otherwise it could slide out

from under you.

The brake lining could get wet

when you wash the scooter. After

washing the scooter, check the

brakes before riding.

Always wear a helmet, gloves,

trousers (tapered around the cuff

and ankle so they do not flap), and

a bright colored jacket.

Do not carry too much luggage on

the scooter. An overloaded scoot-

er is unstable.

EAU50823

Charging the battery safely

Do not charge the battery in areas

potentially exposed to rain or wa-

ter. This could cause an electric

shock or short circuit.

Be sure to plug the charging plug

only directly to a grounded electri-

cal outlet with residual-current de-

vice (RCD) protection to charge

the battery. If incorrectly grounded,

this could cause an electric shock

or short circuit.

If the vehicle is damaged due to

overturning or accident, do not

plug in the charging plug to an out-

let. This could cause an electric

shock or short circuit. Have your

vehicle checked by a Yamaha

EC-03 FEATURES

EAU50470

Features

The features of the EC-03 are follow-

ing:

The driving power source is only

electricity and there is no need for

fuel supply or engine oil change.

High performance motor with

greatly reduced noise and vibra-

tion providing a pleasant ride.

Charging the vehicle can be done

via a grounded electrical outlet

with residual-current device (RCD)

protection.

EAU53920

Traveling distance

TIP

The distance that can be traveled on a

single charge varies according to the

riding and road conditions.

These conditions include the number of

starts and stops, vehicle load, the

steepness of slopes, road conditions,

wind direction and velocity, ambient

temperature, charging status, de-

creased battery performance, and low

tire air pressure.

Distance traveled on a single

charge

The data in the following chart was

measured at Yamaha Motor Co., Ltd. It

was measured when traveling with a

new battery at an ambient temperature

and vehicle load (total weight of rider

and luggage) as shown below on a dry

road surface in the absence of wind.

TIP

The maximum slope ascending capac-

ity is a gradient of approximately 16%

(about 9 degrees).

Because of the battery character,

the riding distance might be re-

duced according to the ambient

temperature due to changes of the

battery temperature.

The distance that can be traveled

becomes 5–10% shorter when the

vehicle load is increased 10 kg.

EAU50344

Effective use of the battery

If the battery is left nearly fully charged

(4–5 segments shown on the battery

charge indicator) and exposed to high

temperature for an extended period, it

will rapidly deplete. To extend the bat-

tery life, handle as follows:

Choose a cool place with no direct

sunlight when charging the bat-

tery.

Do not store the battery with a

charge less than 20% (below the

last segment of the battery level in-

dicator) for an extended period of

time.

Choose a cool and well-ventilated

place without direct sunlight for

storing the vehicle.

When not used for a long period of

time, charge the battery until the

2–3 segments of the battery

charge indicator are shown and

then store the vehicle in a cool

place (optimum temperature 15 C

– 25 C). Check the battery level

while the vehicle is in storage. If

the battery level drops to the last

segment, recharge the battery until

2–3 segments of the battery

charge indicator are shown.

NOTICE
