APPLICATIONS You may use this product for the following purpose:  Charging RYOBI 40 Volt Lithium-ion batteries NOTICE: Charge in a well-ventilated area. Do not block charger vents. Keep them clear to allow proper ventilation. CHARGING See Figures 1 - 2, page 7. Battery packs are shipped in a low charge condition. Therefore, you should charge them before first use. If the charger does not charge your battery pack under normal circumstances, return both the battery pack and charger to your nearest repair center for electrical check. Charge time varies and is dependent upon the amp hour capacity of battery pack.  Turn the battery pack upside down so that the latch faces up.  Attach the charger to the battery pack by aligning the raised ribs on the battery pack with the grooves in the charger, then slide the charger onto the battery pack. NOTE: The connection between the battery pack and charger may feel slightly loose. This is normal and does not indicate a problem.  Press down on the charger to be sure contacts on the battery pack engage properly with contacts in the charger.  The latch should snap into place to ensure charger is correctly connected.  Connect the power adaptor to a power source, then connect the power cable to the charger. NOTE: Make sure the power supply is normal household voltage, 120 volts, AC only, 60 Hz.  Do not place the charger in an area of extreme heat or cold. It will work best at normal room temperature.  The battery pack will become slightly warm to the touch while charging. This is normal and does not indicate a problem.  The LED will slowly flash green while the battery pack is charging. NOTE: If the LED flashes green and red, the charger has detected a fault. See LED Functions for Battery Charging for details.  After charging is complete, the charger LED will stop flashing and remain green for approximately 5 minutes. All battery pack LEDs will turn off to indicate that the battery pack is 100% charged.  To remove the battery pack from the charger, depress the latch and slide the charger off the battery pack.  Remove the power adaptor from the power source. Store charger in a dry location. CHARGING A HOT BATTERY PACK When using a tool continuously, the battery pack may become hot. The charger may be placed directly onto a hot battery pack but charging will not begin until the battery temperature cools to within an acceptable temperature range. When the charger is placed on a hot battery pack the LED will turn orange and remain on. When the battery pack cools, the charger will automatically begin charging. CHARGING A COLD BATTERY PACK The charger may be placed directly onto a cold battery pack but charging will not begin until the battery temperature warms to within an acceptable temperature range. When the charger is placed on a cold battery pack the LED will turn orange and remain on. When the battery pack warms the charger will automatically begin charging. 4 - English
