Hello Jenn21.

Thank you for sharing your experience. A 5-minute runtime on the Greenworks 24V 320 CFM blower with a 2.0Ah battery is below what you should normally expect, as most users see closer to 10–20 minutes depending on how the blower is used. This may indicate an issue with the battery or the connection to the blower.
A few troubleshooting steps that can help:
Confirm the battery is fully charged: The charger should show a solid green light when ready.
Check the battery connection: Make sure the battery clicks firmly into place to ensure a secure fit.
Try another 24V battery if available: If you get normal runtime with a different battery, the original one may be defective.
Monitor for overheating: Batteries that get unusually hot during use may not perform properly.
If you are still experiencing a short runtime after these steps, please reach out to Greenworks support through Live Chat at greenworkstools.com or by calling 1-888-909-6757. We would be happy to help investigate further and review any warranty options available.

Hello Bob89.
We are glad to hear you are getting strong power and runtime from your 24V 12" String Trimmer/Edger, but we are sorry the line feed performance has been frustrating, that is certainly not the experience we want you to have.
Line feeding issues like you described are often related to spool setup or line advancement technique. This model uses an automatic/bump feed system, and for best results:
1. Make sure the spool is properly installed and the line is evenly wound (not crossed or too tight).
2. While trimming, lightly “bump” the head on the ground while the unit is running at full speed to advance the line.
3. Avoid letting the line get too short before feeding, as very short ends can sometimes prevent proper advancement.
4. Check that the correct line diameter is being used, as oversized or undersized line can affect feeding performance.
If the line is consistently not advancing even with proper use, the spool or feed mechanism may need inspection or replacement. Our support team would be happy to help troubleshoot further and ensure everything is functioning as intended. They can be reached either using the online chat function, on Greenworks Tools page, accessible by clicking “Chat Now” in the bottom corner of your screen, Chat with a Live Agent or by calling 1-888-909-6757. So, our experts can discuss your experience; please have your unit, battery and charger with you along with the model and serial number to complete troubleshooting to ensure quick resolution is provided.
