What to do if the line won't advance on my GreenWorks Pro Trimmer?
- JJustin WallAug 5, 2025
If the line on your GreenWorks Pro Trimmer isn't advancing, try these steps: First, lubricate the lines with silicone spray if they are welded together. If there's not enough line on the spool, install more line. If the lines are worn too short, pull both lines while pressing the button. If the lines are tangled, remove them from the spool and rewind them.
