Battery
This generator is equipped with a VRLA (Valve
Regulated lead Acid) battery. There is no need to
check the electrolyte or to add distilled water.
9 Electrolyte is poisonous and dangerous since
it contains sulfuric acid, which causes severe
burns. Avoid any contact with skin, eyes or
clothing and always shield your eyes when
working near batteries. In case of contact,
administer the following FIRST AID.
9 EXTERNAL: Flush with plenty of water.
9 INTERNAL: Drink large quantities of water or
milk and immediately call a physician.
9 EYES: Flush with water for 15 minutes and
seek prompt medical attention.
9 Batteries produce explosive hydrogen gas.
Therefore, keep sparks, flames, cigarettes,
etc., away from the battery and provide suffi-
cient ventilation when charging it in an
enclosed space.
9 KEEP THIS AND ALL BATTERIES OUT OF THE
REACH OF CHILDREN.
To charge the battery
Have a Yamaha dealer charge the battery as soon as
possible if it seems to have discharged.
To charge a VRLA battery, a special (constant-volt-
age) battery charger is required. Using a conven-
tional battery charger will damage the battery. If
you do not have access to a constant-voltage bat-
tery charger, have a Yamaha dealer charge your
battery.
