Common Cautions for the Li­
ion/Ni­MH/Ni­Cd Battery Pack
NOTE:
• When charging a cool battery pack
(below 0°C (3°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 battery pack
may not be fully charged.
• Cool down the charger when charging
more than two battery packs consecutively.
• Do not insert your fingers into contact
hole, when holding charger or any other
occasions.
CAUTION:
To prevent the risk of fire or damage to
the battery charger.
• Do not use power source from an
engine generator.
• Do not cover vent holes on the charger
and the battery pack.

Li­ion Battery Pack
NOTE:
Your battery pack is not fully charged at
the time of purchase. Be sure to charge
the battery before use.
Battery charger (EY0L80)
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.
. Insert the battery pack firmly into the charger.
1 Line up the alignment marks and place the
battery onto the dock on the charger.
 Slide forward in the direction of the arrow.
3. During charging, the charging lamp will be

Alignment marks
electronic switch will automatically be trig-
gered to prevent overcharging.
• Charging will not start if the battery
pack is warm (for example, immediately
after heavy-duty operation).
The orange standby lamp will be flash-
ing until the battery cools down.
Charging will then begin automatically.
4. The charge lamp (green) will flash slowly
once the battery is approximately 80%
charged.
5. When charging is completed, the charging
lamp will start flashing quickly in green color.
6. If the temperature of the battery pack is
0°C or less, charging takes longer to fully
charge the battery pack than the standard
charging time.
Even when the battery is fully charged, it
will have approximately 50% of the power
of a fully charged battery at normal operat-
ing temperature.
7. If the power lamp does not light immediately
after the charger is plugged in, or if after the
standard charging time the charging lamp
does not flash quickly in green, consult an
authorized dealer.
8. If a fully charged battery pack is inserted
into the charger again, the charging lamp
lights up. After several minutes, the charg-
ing lamp may flash quickly to indicate the
charging is completed.
