EAU15951
Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do not
understand, ask your Yamaha dealer.
WARNING
EWA10271
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accidentor injury.
EAU16562
Starting a cold engine NOTICE
ECA10250
See page 5-3 for engine break-in in-
structions prior to operating the ve-hicle for the first time.
1. Turn the key to“”, and when the
oil level warning light comes on,
turn it to“”.NOTICE
ECA10240
If the oil level warning light does not
come on, have a Yamaha dealercheck the electrical circuit.
2. Close the throttle completely.3. While applying the front or rear
brake, start the engine by pushing
the start switch or by pushing the
kickstarter lever down. NOTICE:
For maximum engine life, never
accelerate hard when the en-
gine is cold!
[ECA11041]
If the engine fails to start by push-
ing the start switch, release the
switch, wait a few seconds, and
then try again. Each starting at-
tempt should be as short as possi-
ble to preserve the battery. Do not
crank the engine more than 5 sec-
onds on any one attempt. If the en-
gine does not start with the starter
motor, try using the kickstarter.

Periodic maintenance and lubrication chart TIP

The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.


From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).


Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and technicalskills.

Battery A poorly maintained battery will corrode
and discharge quickly. The electrolyte
level, battery lead connections and
breather hose routing should be
checked before each ride and at the in-
tervals specified in the periodic mainte-
nance and lubrication chart.
To check the electrolyte level
1. Place the scooter on a level sur-
face and hold it in an upright posi-
tion.
TIPMake sure that the scooter is posi-
tioned straight up when checking theelectrolyte level.
2. Remove panel A. (See page 6-6.)
3. Check the electrolyte level in the
battery.TIPThe electrolyte should be between theminimum and maximum level marks.
4. If the electrolyte is at or below the
minimum level mark, add distilled
water to raise it to the maximum
level mark. NOTICE: Use onlydistilled water, as tap water con-
tains minerals that are harmful
to the battery.
[ECA10611]
WARNING
EWA10760


Electrolyte is poisonous and
dangerous since it contains sul-
furic acid, which causes severe
burns. Avoid any contact with
skin, eyes or clothing and al-
ways shield your eyes when
working near batteries. In case
of contact, administer the fol-
lowing FIRST AID.
EXTERNAL: Flush with plenty
of water.
INTERNAL: Drink large quan-
tities of water or milk and im-
mediately call a physician.
EYES: Flush with water for 15
minutes and seek prompt
medical attention.


Batteries produce explosive hy-
drogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and pro-
vide sufficient ventilation when
charging it in an enclosed
space.

KEEP THIS AND ALL BATTER-
IES OUT OF THE REACH OFCHILDREN.
5. Check and, if necessary, tighten
the battery lead connections and
correct the breather hose routing.
To store the battery
1. If the scooter will not be used for
more than one month, remove the
battery, fully charge it, and then
place it in a cool, dry place.
NOTICE: When removing the
battery, be sure the key is
turned to“”, then disconnect
the negative lead before discon-
necting the positive lead.
[ECA16302]
2. If the battery will be stored for more
than two months, check the specif-
ic gravity of the electrolyte at least
once a month and fully charge the
battery whenever necessary.
3. Fully charge the battery before in-
stallation.
4. After installation, make sure that
the battery leads are properly con-
nected to the battery terminals and
that the breather hose is properlyrouted, in good condition, and not
obstructed. NOTICE: If the
breather hose is positioned in
such a way that the frame is ex-
posed to electrolyte or gas ex-
pelled from the battery, the
frame could suffer structural
and external damages.
[ECA10601]EAU23503
Replacing the fuse The fuse holder is located behind panel
A. (See page 6-6.)
If the fuse is blown, replace it as fol-
lows.
1. Turn the key to“” and turn off all
electrical circuits.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.
