What to do if the line does not advance on GreenWorks Trimmer?
- T
  Thomas JonesAug 21, 2025
  If the line on your GreenWorks Trimmer isn't advancing, several factors could be at play. 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, requiring you to install more. If the lines are worn too short, try advancing the cutting line. Lastly, tangled lines on the spool can cause this issue; remove the lines and rewind them.

  If the line on your GreenWorks Trimmer is constantly breaking, it might be due to incorrect machine usage. To prevent this, cut with the tip of the line, avoiding stones, walls, and other hard objects. Also, advance the cutting line regularly to maintain a full cutting width.

  If grass is winding around the trimmer head and motor housing of your GreenWorks Trimmer, it's likely due to 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 the string on your GreenWorks Trimmer isn't advancing when using the bump-feed head, here's what you can do: 1. If the string is welded to itself, lubricate it with silicone spray. 2. If there's not enough string on the spool, install more string. 3. If the string is worn too short, pull the string while pressing the line release button. 4. If the string is tangled on the spool, remove it and rewind it.

What to do if my GreenWorks GD40BCB stops while cutting?
- K
  Katie JonesSep 5, 2025
  If your GreenWorks Trimmer stops while you're cutting, there could be several reasons. First, ensure the guard is properly attached. If you're using heavy cutting line, switch to a 2 mm diameter nylon cutting line. Grass winding around the motor shaft or trimmer head can also cause this; stop the machine, remove the battery, and clear any grass. Overloaded motor is another potential cause; remove the trimmer head from the grass, and it should recover. When cutting, move the trimmer head in and out of the grass, removing no more than 20 cm in a pass. Overheating of the battery pack or machine can also cause the tool to stop. Cool the components and try again. Ensure the battery pack is correctly installed and charged.
