Dewalt 90567079 SA Lever Single Line 14 for Trimmer

The Dewalt 90567079 Trimmer SA Lever Single Line 14 is a switch that is used to connect the single-line feed system with string trimmer head assemblies during use. It is fitted in the lower housing and connected to the spool retention mechanism to be able to allow incremental line advance when the proper button is enabled. Its motion converts hand feedback to mechanical discharge within the rotating head design. It is built into the feed control configuration to allow communication of the stationary elements of the housing with the rotating spool. This integration ensures that line extension and cutting stability are maintained during regular cycles.
