  If your GreenWorks Pro Trimmer isn't starting when you push the trigger, there could be a few reasons. First, check the electrical contact between the machine and the battery pack by removing and reinstalling the battery. The battery pack might be depleted, so ensure it's charged. Also, make sure you're pushing the lock-out button and trigger at the same time—push and hold the lock-out button, then pull the trigger to start the machine.

  If the line on your GreenWorks Pro Trimmer isn't advancing, it could be due to a few reasons. You might not have enough line on the spool, so install more line. The lines could be worn too short, so try advancing the cutting line. Alternatively, the lines might be tangled on the spool; remove them and wind them properly.

  If the line on your GreenWorks Pro Trimmer keeps breaking, it might be due to incorrect usage. Ensure you're cutting with the tip of the line and avoiding hard objects like stones and walls. Regularly advance the cutting line to maintain a full cutting width.

  If the vibration in your GreenWorks Pro Trimmer increases noticeably, it may be because the line is worn down on one side and not advanced in time. Ensure the line on both sides is normal and advance the line.
