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 TIPThe 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 lowtire 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.
TIPThe 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-

Check the charging plug for any
foreign objects such as dust,
soil, oil or water before charg-
ing. If necessary, wipe the plug
clean with a dry cloth.

Do not use an ungrounded ex-
tension cord or a multi-outlet
plug between the charging cord
and the outlet.

Do not use the electrical outlet along with other electrical
equipment which may exceed
the outlet’s amperage and over-
heat the outlet.

Be sure to plug in the chargingplug firmly.
9. When the charging plug is plugged into an electrical outlet, charging
starts automatically. The battery

Checking the front and rear
brake shoes Front
Rear The front and rear brake shoes must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart. Each brake is provid-
ed with a wear indicator, which allows
you to check the brake shoe wear with-
out having to disassemble the brake.
To check the brake shoe wear, check
the position of the wear indicator while
applying the brake. If a brake shoe has
worn to the point that the wear indicator
reaches the wear limit line, have a
Yamaha dealer replace the brake
shoes as a set.
EAU23095
Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.
WARNING! Damage to the outer
housing of cables may result in in-
ternal rusting and cause interfer-
ence with cable movement. Replace
damaged cables as soon as possi-
ble to prevent unsafe condi-
tions.

893. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
4. Use spray oil as a universal clean- er to remove any remaining dirt.
5. Touch up minor paint damage caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely be- fore storing or covering it.
WARNING
EWA15820
Contaminants on the brakes or tires
can cause loss of control.
Make sure that there is no oil or
wax on the brakes or tires. If
necessary, wash the tires with
warm water and a mild deter-
gent.

Before operating the scooter,
test its braking performanceand cornering behavior.
NOTICE
ECA10800

Apply spray oil and wax spar-
ingly and make sure to wipe off any excess.

Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.

Avoid using abrasive polishing
compounds as they will wearaway the paint.
TIP
Consult a Yamaha dealer for ad-
vice on what products to use.

Washing, rainy weather or humid
climates can cause the headlight
lens to fog. Turning the headlight
on for a short period of time will
help remove the moisture from thelens.
EAU50843
Storage Short-term
Always store your scooter in a cool, dry
place and, if necessary, protect it
against dust with a porous cover. Be
sure the motor is cool before covering
the scooter.NOTICE
ECA17130

Storing the scooter 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, power
unit failure, electric leakage, or
short-circuiting.

To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-cals are stored.
Long-term
NOTICE
