BATTERY OPERATION
DIAGNOSTICS
The Model 8924 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, as follows:
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.
If the green light flashes slowly after battery pack is inserted in charger, 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.
If the red light flashes continuously, the battery pack has failed (pack is not chargeable and requires replacement).
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.
