Operation

Charging the Battery Pack

Important: The battery pack is not fully charged when you purchase it. Before using the tool for the first time, place the battery pack in the charger and charge it until the LED display indicates the battery pack is fully charged. Read all safety precautions.

Important: Charge the battery pack only in temperatures that are within the appropriate range; refer to Specifications.

Note: At any time, press the battery-charge-indicator button on the battery pack to display the current charge (LED indicators).

  1. Ensure that the vents on the battery charger are clear of any dust and debris.

  2. Line up the cavity in the battery pack (Figure 3) with the tongue on the charger.

  3. Slide the battery pack into the charger until it is fully seated (Figure 3).

    Note: During normal operation, a fan sound is audible from the charger while the battery pack is charging.

  4. If multiple battery packs are connected to the charger, you can switch between batteries or charge both at the same time by pressing the charging mode button on the side of the charger.

    • Parallel charging: All connected battery packs are charged in parallel, to the same level. This results in all connected batteries being evenly charged.

    • Sequential Rapid charging: A single battery is given charging priority. This results in the priority battery being fully charged before the other attached battery.

      Note: The LED indicator lights to the left and right of the button tells you which side has charging priority; if both are lit at once the charger is in the Parallel charging setting.

  5. Refer to the following table to interpret the LED indicator lights on the battery charger.
