- When the battery is inserted properly, the green LED indicator will slowly flash to indicate that the battery is charging. The red light will turn off.
- When the green light stays on, the battery is fully charged.
WARNING: Do not use the charger outdoors or expose it to wet or damp conditions. Water entering the charger will increase the risk of electric shock.
2. Installing/Removing the Battery
To install the battery, align the battery pack with the base of the tool and slide it in until it clicks securely into place. To remove, press the battery release buttons on the sides of the battery pack and slide it out.
Operating Instructions
1. Changing Bits
The 1/4-inch quick-connect hex chuck allows for tool-free bit changes. Simply pull back the collar, insert the bit, and release the collar to secure it.
