Your Brave grinder is intended for outdoor-use only and can be used to remove many tree stumps and 

exposed root systems 9” high or lower to ground level. Approach the stump from the top, cutting straight down. 

Raise up out of the cut, move over in the desired direction, plunge again.  Repeat these steps across the entire 

stump. Make sure you completely read and understand this manual before using the grinder for the first time.
