Battery
The battery is located under the seat.
(See page 4-8.)
This model is equipped with a VRLA
(Valve Regulated Lead Acid) battery.
There is no need to check the electro-
lyte or to add distilled water. However,
the battery coupler connection needs
to be checked to make sure that it is
securely connected.
WARNING
EWA10761
 Electrolyte is poisonous an d
d an gerous since it contains sul-
furic aci d, which causes severe

To char ge the b attery
Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to
have discharged. Keep in mind that the
battery tends to discharge more quick-
ly if the vehicle is equipped with op-
tional electrical accessories.

hicle, etc.
Check that the motorcycle is in a stable
and level position before starting any
maintenance.

For Europe only
The figures quoted are emission levels
and are not necessarily safe working
levels. Whilst there is a correlation be-
tween the emission and exposure lev-
els, this cannot be used reliably to
determine whether or not further pre-
cautions are required. Factors that in-
fluence the actual level of exposure of
work-force include the characteristics
of the work room, the other sources of
noise, etc. i.e. the number of machines
and other adjacent processes, and the
length of time for which an operator is
exposed to the noise. Also the permis-
sible exposure level can vary from
country. This information, however, will
enable the user of the machine to make
a better evaluation of the hazard and
risk.
