How to fix a GreenWorks Pro Trimmer that won't start?
- GGina SmithJul 28, 2025
If your GreenWorks Pro Trimmer fails to start when the trigger lock button is depressed, make sure the battery pack is properly attached to the trimmer. If it is, remove the battery and reinstall it to ensure good electrical contact. Also, ensure the battery pack is adequately charged. You must press down the lock-off lever and hold it, then depress the trigger to turn on the string trimmer. Ensure that you first press the power button before pressing the trigger.
