•EYES: Flush with water for
15 minutes and seek prompt
medical attention.
•Batteries produce explosive
hydrogen gas. Therefore, keep
sparks, flames, cigarettes, etc.,
away from the battery and
provide sufficient ventilation
when charging it in an enclosed
space.
•KEEP THIS AND ALL BATTE-
RIES OUT OF THE REACH OF
CHILDREN.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.
2. If the battery will be stored for
more than two months, check it
at least once a month and fully
charge it if necessary.
3. Fully charge the battery before
installation.EC000102
•Always keep the battery
charged. Storing a discharged
battery can cause permanent
battery damage.
•To charge a sealed-type (MF)
battery, a special (constant-vol-
tage) battery charger is
required. Using a conventional
battery charger will damage the
battery. If you do not have
access to a sealed-type (MF)
battery charger, have a Yamaha
dealer charge your battery.

SCOOTER CARE AND STORAGE
7 Long-term
Before storing your scooter for several
months:
1. Follow all the instructions in the
"Care" section of this chapter.
2. Drain the carburetor float chamber
by loosening the drain bolt; this will
prevent fuel deposits from building
up. Pour the drained fuel into the
fuel tank.
3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap and
spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit
sparking during the next step.)d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark
plug cap.
EWA00003
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.
5. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
6. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground.
Alternatively, turn the wheels a
little every month in order to
prevent the tires from becoming
degraded in one spot.
WARNING
7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
8. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a month.
Do not store the battery in an
excessively cold or warm place
(less than 0 °C or more than 30
°C). For more information on
storing the battery, see page
6-30.
NOTE :
Make any necessary repairs before
storing the scooter.
