CHARGING BATTERY PACK

1. Plug charger cord into your standard power outlet. With
no battery pack inserted, the charger's green indicator
light will go ON. This indicates the charger is receiving
power and the charger is ready for operation.
2. To remove the battery pack from the tool press both
battery release tabs and pull the battery from the tool.
3. When you insert the battery pack into the charger, the
charger's green indicator light will begin to "BLINK".
This indicates that the battery is receiving a fast charge.
4. When the indicator light stops "BLINKING" (and
becomes a steady green light) fast charging is
complete. The battery pack is fully charged and can be
removed from the charger. The light will stop blinking
in less time if the battery pack was not completely
discharged.
5. When you begin the charging process of the battery
pack, a steady green light could also mean the
battery pack is too hot or too cold. Fast charging
is only possible when the temperature range of
the battery pack is between 0°C and 45°C. When
needed, the internal fan of the charger will turn on to
aid the charging process and speed. As soon as the
battery pack reaches the correct temperature range,
the battery charger will automatically switch to fast
charging.
6. The battery pack may be used even though the light
may still be blinking. The light may require more time
to stop blinking depending on temperature.
7. A substantial drop in operating time per charge may
mean that the battery pack is nearing the end of its life
and should be replaced.
8. Remember to unplug charger during storage period.
