WARNING
Never use a fuse with an amperage rating
other than that specified. Improvising or us-
ing a fuse with the wrong amperage rating
may cause extensive damage to the electri-
cal system, cause the lighting and ignition
systems to malfunction and could possibly
cause a fire.

CHECKING AND CHARGING THE BATTERY

EWA13290
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poi-
sonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
Wear protective eye gear when handling or
G
working near batteries.
Charge batteries in a well-ventilated area.
G
Keep batteries away from fire, sparks or
G
open flames (e.g., welding equipment,
lighted cigarettes).
DO NOT SMOKE when charging or han-
G
dling batteries.

OUT OF REACH OF CHILDREN.
Avoid bodily contact with electrolyte as it
G
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
Skin — Wash with water.
G
Eyes — Flush with water for 15 minutes and
G
get immediate medical attention.
INTERNAL
Drink large quantities of water or milk fol-
G
lowed with milk of magnesia, beaten egg or
vegetable oil. Get immediate medical atten-
tion.

CAUTION:
This is a sealed battery. Never remove the
G
sealing caps because the balance between
cells will not be maintained and battery per-
formance will deteriorate.
Charging time, charging amperage and
G
charging voltage for an MF battery are dif-
ferent from those of conventional batteries.
The MF battery should be charged as ex-
plained in the charging method illustra-
tions. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charging
the battery.
NOTE:
Since MF batteries are sealed, it is not possible
to check the charge state of the battery by mea-
suring the specific gravity of the electrolyte.
Therefore, the charge of the battery has to be
checked by measuring the voltage at the battery
terminals.
