The LCD screen will display the battery percentage and a lightning bolt icon, indicating it is charging. The lightning bolt icon will stop flashing when fully charged.

The screwdriver features a magnetic bit holder for easy and secure bit changes.

1. Select the appropriate S2 metal bit for your task.

3. To remove, pull the bit straight out.
