OVERLOAD

Your drill has a built-in overload protector to protect the motor during overloading or prolonged use. The overload protector
automatically activates to break the circuit. When this occurs, allow your drill to cool a few seconds before resuming
operation.
IMPORTANT INFORMATION FOR RECHARGING HOT BATTERIES USING CHARGER PART
NUMBER 1400677
When using your drill-driver continuously, the batteries in your battery pack will become hot. You should let a hot battery
pack cool down for approximately 30 minutes before attempting to recharge. When the battery pack becomes discharged
and is hot, this will cause the red light on your battery charger to flash. When battery pack cools down, red light will glow
continuously indicating fast charging mode, 1 hour charge time. Once the battery pack cools down, it will recharge battery
pack in fast charging mode as normal.
IMPORTANT INFORMATION FOR RECHARGING HOT BATTERIES USING CHARGER PART
NUMBER 1400666, 1400656, OR 1400667
When using your drill-driver continuously, the batteries in your battery pack will become hot. You should let a hot battery
pack cool down for approximately 30 minutes before attempting to recharge. When the battery pack becomes discharged
and is hot, this will cause the yellow and green lights on your battery charger to come on instead of the red light. The yellow
and green lights indicate soft start mode and will switch to green only, indicating slow charge mode. The red light indicates
fast charge mode, 1 hour charge time. The green light indicates slow charge mode, requiring overnight charging for
batteries to reach full charge. If the green light comes on after letting battery pack cool down, remove it from charger for
additional cooling.
Once the battery pack cools down, it will recharge battery pack in fast charging mode as normal.
Do not leave a hot battery pack in charger until it cools down. The green light will not go off when battery pack cools. If fast
charge mode is desired, you must physically remove a hot battery pack from the charger, let it cool, then place it back in
charger after it has cooled down. Once the battery pack cools down, it will recharge battery pack in fast charging mode as
normal.
NOTE: This situation only occurs when continuous use of your drill-driver causes the batteries to become hot. It does not
occur under normal circumstances. Refer to "CHARGING YOUR DRILL-DRIVER" for normal recharging of batteries.
If the charger does not charge your battery pack under normal circumstances, return both the battery pack and charger to
your nearest Ryobi Authorized Repair Center for electrical check.
