Today, while weed eating, I managed to get a piece of wire wrapped around the drive shaft of my weed eater. Taking the head unit apart was quite simple. The steps are documented below for anyone who needs to open up their kobalt weed eater.
Tools Needed: 1 Philips head screw driver. 1 20T Torx screw driver.
First, remove the trimmer guide (the silver metal bar that flips up/down). Just pull it out of the holes that it fits in. Next remove the two philips head screws holding the trimmer guard in place. Slide the guard off. Now remove the torx screws. Notice that removing the guard exposes two more torx screws. Once all the screws are removed, the motor housing comes apart easily.
