BATTERY OPERATION

CHARGING THE BATTERY PACK GENERAL

Before using your cordless tool for the first time, the battery pack should be fully charged. If the battery pack is installed, remove it by following instructions under INSTALLING OR REMOVING BATTERY PACK.

As a battery pack approaches the discharged state, you will notice a sharp drop in tool performance. When the tool is unable to perform the task at hand, it is time to recharge the battery pack. Recharging the battery pack before this condition is reached will reduce the total work life of the pack. Discharging the pack beyond this point can damage the pack.

NOTE: Battery temperature will increase during and shortly after use. Batteries may not accept a full charge if they are charged immediately after use. Allow the battery pack to cool to room temperature before charging for best results.

The battery charger may rest on the four pads provided on the bottom of the case or be mounted on a wall by utilizing the two key hole slots provided.

CAUTION: Vent slots in top and bottom of charger must not be obstructed. Do not charge battery when temperature is BELOW 40°F or ABOVE 104°F (4.4/40°C).

NORMAL CHARGING

Make sure power circuit voltage is the same as that shown on the charger specification plate. Connect charger to power source. The red and green lights will flash once to indicate that power is connected properly and the charger is ready for operation.

Position the battery pack on charger, align rails on battery pack (A) Fig. 13 with four tabs (C) Fig. 12 on charger. Slide battery forward on charger until it stops.

The green light (A) Fig. 12 should begin to flash rapidly indicating that the battery pack is receiving a “fast charge”. (If the green light does not flash or if the red light (B) illuminates, see DIAGNOSTICS”). After approximately one hour, the “Fast Charge” indicator light should glow continually, indicating that the battery pack is fully charged and that the charger is now in a “Maintenance Charge” mode. The battery pack can be left on “Maintenance Charge” until you are ready to use it.

Depending on room temperature, line voltage, and existing charge level, initial battery charging may take longer than one hour.

Disconnect charger from power source when not in use.
