WARNING
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.
Operating range of DC power supply
(exclusively for charging 12V battery)
762-012
This power source is designed to charge batteries up
to 40Ah that are half-discharged. Do not charge batter-
ies of a higher capacity than 40Ah.
12V battery
The time required for recharging a battery varies
depending on the discharge level of the battery. When
the specific gravity of the battery reaches 1.26 to 1.28,
charging is complete. When charging, check the bat-
tery's specific gravity once an hour.
The average time for charging a half-discharged 40Ah
battery is approximately 5 hours. Be sure to check the
battery fluid level before charging.
NOTICE
9 Do not connect any load to the battery or use
the engine starter motor while charging.
This causes high current to flow through the
generator which will burn out the coil.
9 Do not connect a VRLA (Valve Regulated Lead
Acid) battery. To charge a VRLA battery, a spe-
cial (constant-voltage) battery charger is
required.
