Istruzioni per l'uso
The McCulloch Universal Trimmer Head P25 is designed for efficient cutting of short to medium length grass and light bushes.
- Avvio del trimmer: Follow your trimmer's manufacturer instructions for starting the engine.
- Tecnica di rifinitura: Hold the trimmer firmly with both hands. Use a sweeping motion to cut grass. Avoid hitting hard objects like rocks, fences, or concrete, as this can damage the line and the trimmer head.
- Avanzamento di linea: The P25 features an automatic line advancement system. When the line wears down, simply tap the trimmer head lightly on the ground while the engine is running at operating speed. This will release a small amount of new line. The cutting blade on your trimmer's guard will automatically trim the line to the correct length.
- Prestazioni ottimali: For best results, maintain a consistent engine speed and avoid overloading the trimmer head by trying to cut too much material at once.

Una manutenzione regolare garantisce la longevità e le prestazioni ottimali della testina del decespugliatore.
- Pulizia: After each use, clean the trimmer head to remove grass clippings, dirt, and debris. Use a brush or cloth. Do not use harsh chemicals.
- Sostituzione della linea: When the pre-loaded line is depleted, replace it with a new spool of 2.0 mm trimmer line, such as the McCulloch SPO001 replacement spool.
- Replacing the Spool:
- Ensure the trimmer is off and the spark plug wire is disconnected.
- Locate the tabs or buttons on the side of the trimmer head. Press them in and pull the cap off.
