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
internal electronic switch will
automatically be triggered to pre-
vent 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
flashing until the battery cools down.
Charging will then begin automati-
cally.
4. The charge lamp (green) will flash
slowly once the battery is approxi-
mately 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 operating temperature.
7. If the power lamp does not light im-
mediately after the charger is plugged
in, or if after the standard charging
time the charging lamp does not flash
quickly in green, consult an author-
ized service center.
8. If a fully charged battery pack is in-
serted into the charger again, the
charging lamp lights up. After sev-
eral minutes, the charging lamp may
flash quickly to indicate the charging
is completed.
Ni-MH/Ni-Cd Battery Pack
NOTE:
When you charge the battery pack
for the first time, or after prolonged
storage, charge it for about 24
hours to bring the battery up to full
capacity.
