What are the troubleshooting steps if the line does not feed from the spool of a trimmer head?
If the line does not feed from the spool during use, check the following: For STIHL AutoCut trimmer heads, attempt automatic readjustment by tapping the rotating head on the ground (line output is possible if ends are at least 2.5 cm). If the spool is empty, reload it with new cutting line. If the lines are shorter than 2.5 cm, manually pull the ends out of the spool after stopping the engine. Finally, check if the trimmer head is worn or if line remnants are blocking the mechanism; replace the entire trimmer head if heavily worn.
