How to rewind the trimmer line into its housing?
The procedure for winding the line varies depending on the trimmer head model. Some models advance the line automatically (STIHL SuperCut, STIHL AUTOCUT), while others require manual adjustment or replacement (STIHL TrimCut, STIHL FixCut). STIHL PolyCut models use nylon lines or polymer blades. To reduce the risk of injury, switch off the engine before adjusting the line manually.
