Forward/Reverse Rotation
Forward Rotation: For driving in screws, push the Forward/Reverse switch to the Right position.
Reverse Rotation: For loosening or unscrewing screws, push the Forward/Reverse switch to the Left position.
No Rotation: Set the Forward/Reverse switch to the Center position to lock the bit chuck from spinning. The bit chuck also locks when the Power button is not pressed. The locked chuck enables you to use the tool as a regular hand tool screwdriver.
