Make sure that all items listed in the packing list are included. n Inspect the tool carefully to make sure no breakage or damage occurred during shipping. n Do not discard the packing material until you have carefully inspected and satisfactorily operated the tool. A damaged charger may damage a battery pack. BATTERY SHOWN IN CHARGER CHARGING THE BATTERY PACK The battery pack for this tool has been shipped in a low charge condition to prevent possible problems. Therefore, you should charge overnight prior to use. 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. n Charge battery pack only with the charging assembly provided. n Make sure power supply is normal household voltage, 120 volts, 60 Hz, AC only. 2 OPERATION CHARGING A HOT BATTERY PACK When using the tool continuously, the batteries in the battery pack will become hot. You should let a hot battery pack cool down for approximately 30 minutes before attempting to recharge.
