2.Grasp the handles firmly with both hands. When you are sure that no people or animals are in the vicinity, and it’s safe to begin, depress the Switch (107).
3.As you break the concrete into big chunks, release the Switch (107) and move to other large pieces until all of the larger pieces are broken. Do not try to break up smaller pieces with this tool as it is too powerful and aggressive to control on small pieces.
