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.
2. Insert the battery pack firmly into the
charger.
1 Line up the alignment marks and
place the battery onto the dock on
the charger.
2 Slide forward in the direction of the
arrow.
3. During charging, the charging lamp will
be lit.
When charging is completed, an inter-
nal electronic switch will automatically
be triggered 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
flashing until the battery cools down.
Charging will then begin automatically.
Alignment marks
4. The charge lamp (green) will flash
slowly once the battery is approxi-
mately 80% charged.
5. When charging is completed, the charg-
ing lamp will start flashing quickly in
green color.
6. If the temperature of the batter 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 nor-
mal operating temperature.
7. If the power lamp does not light imme-
diately 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 in-
serted into the charger again, the
charging lamp lights up. After several
minutes, the charging lamp may flash
quickly to indicate the charging is
completed.
