Introduction
The spring is placed behind the metal ball spring and the sleeve. The spring provides the mechanisms for releasing and holding the drill bits. Without the spring, the impact driver will start to wobble and will make it difficult to screw in screws adequately.
Make sure that you have a clean surface to work on and not lose any of the small parts.
Remove the driver’s battery before beginning.
