How to Use Your SharperBlade
Trimming
Trim Grass and Edges
With the blade and guard properly installed, operate the trimmer according to your model's starting and trimming instructions. Keep hands and feet away from the rotating blade and maintain a stable stance.
Blade Care
Inspect After Use
Switch OFF and unplug before inspection or cleaning. SharperBlade is designed to wear gradually and expose a fresh cutting edge; replace it if it becomes damaged or too worn for effective cutting.
Why SharperBlade? Its nylon-and-polymer construction and self-sharpening design are intended to simplify trimming without the routine restringing associated with line trimmers. Always follow the safety precautions in your operator's manual.
