      If the line on your GreenWorks Trimmer keeps breaking, it might be due to incorrect usage. Try cutting with the tip of the line, and avoid contact with stones, walls, and other hard objects. Also, regularly advance the cutting line to maintain a full cutting width.

      If grass is winding around the trimmer head and motor housing of your GreenWorks Trimmer, it's likely because you're cutting tall grass at ground level. Cut tall grass from the top down, removing no more than 8 inches in each pass to prevent wrapping.

      If your GreenWorks Trimmer doesn't start, several issues might be the cause. First, there may be a poor electrical connection between the battery and the machine. Try removing the battery, checking the contact points, and reinstalling it. Second, the battery pack might be depleted, so you should charge it. Finally, ensure you are simultaneously pressing the lock-out button and the trigger. Pull and hold the lock-out button, then pull the trigger to start the trimmer.

      If you notice a significant increase in vibration in your GreenWorks Trimmer, it could be because the line is worn down on one side and hasn't been advanced in time. Check that the line on both sides is normal and advance the line as needed.

    How to fix GreenWorks Trimmer line that won't advance?

      Timothy GarciaSep 2, 2025
      If the line on your GreenWorks Trimmer isn't advancing, there are a few potential reasons. The lines might be welded together, in which case you should lubricate them with silicone spray. Alternatively, there might not be enough line on the spool, so install more line. If the lines are worn too short, try advancing the cutting line. Finally, the lines could be tangled on the spool; remove them and wind them neatly.
