Before operating, ensure you have read and understood all safety warnings.
- Starting the Trimmer:

- Press the safety lock-out button (if applicable) and then squeeze the variable speed trigger to start the motor.
- The motor speed will increase as you squeeze the trigger further.
- Trimming Technique:
- Use a sweeping motion, moving the trimmer from side to side.
- Maintain a consistent cutting height by keeping the trimmer head level with the ground.
- For edging, tilt the trimmer head to a vertical position and guide it along the edge of sidewalks or driveways.
- Extending Trimmer Line (Bump Feed):
- While the trimmer is running at full speed, gently tap the bump-feed head on a firm surface (e.g., the ground).
- This action will release a small amount of new trimmer line. The line cut-off blade on the deflector will trim it to the correct length.
