Adjusting Blade Depth

Operating Instructions
General Operation
Connect the edger to a suitable extension cord, ensuring the cord retention system is engaged. Hold the tool firmly with both hands, using the assist handle for better control.

Edging and Trenching
For edging, position the tool so the blade aligns with the desired edge. For trenching, utilize the exclusive pull-up edge guide to convert the tool. This allows for deeper cuts suitable for installing outdoor lighting or invisible dog fencing. Maintain a steady pace and allow the motor to do the work.

- Poor cutting performance: The blade may be dull or damaged. Replace the blade if needed. Also, ensure the blade depth is set appropriately for the task.
- Excessive vibration: A bent or damaged blade can cause vibration. Inspect the blade and replace it if necessary.
