2-in-1 Trimming and Edging
This tool easily converts between trimming and edging modes. For trimming, hold the unit parallel to the ground. For edging, rotate the head 90 degrees and use the edger guide wheel to maintain a consistent line along sidewalks and driveways.

Automatic Line Feed System
The innovative auto line feed system ensures continuous cutting performance without manual adjustments. When the line becomes too short, the system automatically extends it. If the line is too long, the trimmer will automatically trim the excess.

Adjustable Angle and Telescopic Shaft
The trimmer head can be adjusted to various angles (0°, 30°, 45°, 60°, 90°) to reach difficult areas. The telescopic shaft allows for height customization, improving comfort and control during operation.

Maintenance
- Cleaning: After each use, remove the battery and clean the trimmer head and guard with a dry cloth to remove grass clippings and debris. Do not use water or solvents.

- Battery Care: Store batteries in a cool, dry place. Do not expose to extreme temperatures. Charge batteries fully before long-term storage and recharge every 3-6 months to maintain battery health.
- Inspection: Regularly inspect the trimmer for any loose parts, damage to the guard, or wear on the cutting line. Replace damaged parts immediately.
