2. Two-Speed Select
The trimmer features a two-speed selector switch. Use the lower speed for extended runtime and lighter trimming tasks, and the higher speed for maximum power when tackling dense or tough vegetation.

3. Dual Line Bump Feed
To advance more cutting line, simply tap the trimmer head gently on the ground while the trimmer is running. The dual line bump feed mechanism will release additional line automatically.

4. Trimming Techniques
