Battery Pack Life
The rechargeable batteries have
a limited life. If the operation time
becomes extremely short after
recharging, replace the battery pack
with a new one.
Charging Charging
NOTE:
When you charge the battery pack for
the first time, or after prolonged stor-
age, charge it for about 24 hours to
bring the battery up to full capacity.
Battery charger (EY0110)
1. Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the
plug is inserted into the AC power
supply, but this is not a problem in
terms of safety.

3. During charging, the charging lamp
will be lit.
When charging is completed, an
internal electronic switch will auto-
matically be triggered to prevent
overcharging.
Charging will not start if the battery
pack is warm (for example, immedi-
ately after heavy-duty operation).
The orange standby lamp will be lit
until the battery cools down. Charging
will then begin automatically.
4. When charging is completed, the
charging lamp will start flashing quick-
ly in green color.
5. When in any of the conditions that
battery pack is too cool, or the bat-
tery pack has not been used for a
long time, the charging lamp is lit. In
this case, charging takes longer to
fully charge the battery pack, than the
standard charging time.
If a fully charged battery pack is
inserted into the charger again, the
charging lamp light up. After sev-
eral minutes, the charging lamp may
flash quickly to indicate the charging
is completed.
6. If the charging lamp does not light im-
mediately after the charger is plugged
in, or if after the standard charging
time the lamp does not go off, consult
an authorized dealer.
NOTE:
When charging a cool battery pack
(below 5°C (41°F)) in a warm place,
leave the battery pack at the place
and wait for more than one hour to
warm up the battery to the level of the
ambient temperature. Otherwise bat-
tery pack may not be fully charged.
Cool down the charger when
charging more than two battery
packs consecutively.
Do not insert your fingers into con-
tact hole, when holding charger or
any other occasions.
CAUTION:
Do not use power source from an
engine generator.
Do not cover vent holes on the
charger and the battery pack.
