RECHARGING HOT BATTERIES
When using your hammer drill continuously, the batteries in your battery pack become hot. You should let a hot battery pack cool down for approximately 30 minutes before attempting to recharge.
Note: This situation occurs when continuous use of your hammer drill causes the batteries to become hot. It does not occur under normal circumstances. Refer to CHARGING BATTERIES for normal recharging of batteries. If the charger does not charge your battery pack under normal circumstances, return both the battery pack and charger/charging assembly to your nearest Ryobi Authorized Service Center for electrical check.
