      Clinton WebsterAug 22, 2025
      If the line on your Toro Trimmer won't advance when using automatic line lengthening, consider these possible causes: * The line may be welded to itself. If so, lubricate it with silicone spray. * There might not be enough line on the spool. Install more line. * The line could be worn too short. Pull the line while alternately pressing down on and releasing the retaining cap. * The line may be tangled on the spool. Remove the line and rewind it. * The engine speed may be too slow. Advance the line at full throttle.

      If the line on your Toro Trimmer won't advance automatically, try these steps: First, lubricate the line with silicone spray if it seems welded together. If there's not enough line, install more. If the line is too short, pull it while pressing and releasing the retaining cap. If the line is tangled, remove it from the spool and rewind it. Lastly, make sure the engine is at full throttle when advancing the line.
