Operating Instructions
This section details how to effectively use your BLACK+DECKER BESTA525 for trimming and edging.
Trimming Operation
For general grass trimming, hold the trimmer with both hands, ensuring a balanced grip. Keep the cutting head parallel to the ground. Move the trimmer in a sweeping motion from side to side, cutting small amounts of grass at a time. The AFS (Automatic Feed System) will automatically feed line as needed, ensuring continuous cutting performance.

Edging Operation
To convert to edging mode, simply rotate the cutting head 90 degrees. This can be done tool-free. The integrated guide wheel helps maintain a consistent cutting depth and a clean, straight edge along sidewalks, driveways, and flower beds. Walk slowly and steadily, allowing the guide wheel to follow the edge.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your trimmer.
- Cleaning: After each use, disconnect the power and clean the trimmer with a damp cloth. Remove any grass clippings or debris from the cutting head and guard. Do not use harsh chemicals or abrasive cleaners.
- Line Replacement: The AFS system automatically feeds line. If the line runs out, replace the spool with a genuine BLACK+DECKER replacement spool. Refer to the diagram on the spool for correct winding direction if manually rewinding.
- Storage: Store the trimmer in a dry, secure place, out of reach of children. Ensure the power cord is neatly coiled and not kinked.
