OPERATION

CHARGING THE BATTERY PACK GENERAL

Before using your cordless Driver/Drill for the first time, the battery pack should be fully charged. If the battery pack is installed in the Driver/Drill, 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 32°F or ABOVE 104°F.

NORMAL CHARGING

Make sure power circuit voltage is the same as that shown on the charger specification plate. Connect charger to power source. The green light (A) Fig. 5, should begin to flash. This indicates the charger is ready to begin charging.

Position the battery pack on charger, align rails (A) Fig. 6 on battery pack with four tabs (C) Fig. 5 on charger. Slide battery forward onto charger until it stops.

The green light (A) Fig. 5, should begin to glow continuously, indicating that the battery pack is receiving a “Fast Charge” (if the green light does not glow continuously, or if the red light (B) Fig. 5, also begins to flash: see DIAGNOSTICS). After approximately one hour, the “Fast Charge” indicator light should go out indicating that the battery pack is fully charged and that the charger is now in a “Trickle Charge” mode. The battery pack can be left on “Trickle 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.

DIAGNOSTICS

The Model 8624 Charger is equipped with a diagnostic system that automatically checks the battery pack each time a pack is inserted into the charger. If no problems are found, the charger will automatically switch to “Fast Charge” mode as described in NORMAL CHARGING. If a problem is found, it will be indicated by the charger indicator lights (see Fig. 5), as follows:

•Green light (A) continues to flash after battery pack is inserted in charger: indicates that the battery pack temperature is either too high or too low for charging. If left alone, the charger will continue to monitor the battery pack temperature and will begin charging when the temperature reaches an

acceptable level.
