Electrolyte is poisonous and
dangerous since it contains
sulfuric acid, which causes
severe burns. Avoid any con-
tact with skin, eyes or clothing
and always shield your eyes
when working near batteries.
In case of contact, administer
the following FIRST AID.

EXTERNAL: Flush with plen-
ty of water.

tities of water or milk and

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.

6 To charge the battery
Have a Yamaha dealer charge the
battery as soon as possible if it
seems to have discharged. Keep in
mind that the battery tends to dis-
charge more quickly if the motorcycle
is equipped with optional electrical
accessories.
To store the battery
1. If the motorcycle 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.
4. After installation, make sure that
the battery leads are properly
connected to the battery termi-
nals.

battery charger, have a
Yamaha dealer charge your
battery.
