CHARGING BATTERY PACK
The battery pack for this tool has been shipped in a low charge condition to prevent possible problems. Therefore, you should charge it until the light on front of charger changes from flashing green to continuous green.
Note: Batteries will not reach full charge the first time they are charged. Allow several cycles (operation followed by recharging) for them to become fully charged. This is nominal for
TO CHARGE
■Charge battery pack only with the charger provided.
■Make sure power supply is normal house voltage, 120 volts, 60 Hz, AC only.
■Connect the charger to a power supply.
■Attach battery pack to charger by aligning raised ribs on battery pack with grooves in charger, then slide battery pack onto charger. See Figure 2.
■After normal usage, 30 minutes of charging time is required to be fully charged.
■The battery pack will become slightly warm to the touch while charging. This is normal and does not indicate a problem.
■Do not place charger in an area of extreme heat or cold. It will work best at normal room temperature.
■When the batteries become fully charged, unplug your charger from power supply and remove the battery pack.
IMPORTANT INFORMATION FOR RECHARG- ING HOT BATTERY PACK
When using this tool continuously, the batteries in the battery pack will become hot. The battery pack for this tool will charge more rapidly and efficiently when at a cooled temperature.
The internal fan for this charger will automatically turn on when a battery pack is inserted. Air circulates through the battery, bringing it to optimum charging temperature, de- creasing the time required to begin fast charging the pack, and extending the life of the battery.
Note: The fan will start to run and continue to run until the battery pack is removed from the charger.
When the battery pack becomes discharged and is hot, the green LED will be off and the red LED will begin flashing.
When the battery pack cools down to approximately 104°F (40°C), the charger will automatically begin fast charge mode.
