Installation Steps
Follow these steps to correctly install the replacement spool and cap cover on your Greenworks string trimmer:
- Turn off the engine: Ensure the trimmer is powered off and the battery is removed (for cordless models) or unplugged (for corded models) before beginning installation.
- Remove the cap: Press the tabs on the side of the trimmer head and carefully remove the existing cap cover.
- Replace the spool: Remove the old spool. Place the new THTEN replacement spool into the trimmer head. Ensure the line is threaded through the eyelet on the trimmer head.
- Line up the retainer: Align the retainer on the cap cover with the corresponding slot on the outside of the trimmer head.
- Cover the trimmer cap: Press the cap cover firmly onto the trimmer head until it clicks into place, securing the spool.

Usage Guidelines
When operating your string trimmer with the new THTEN spools, always wear appropriate safety gear, including eye protection, long pants, and sturdy footwear. Maintain a firm grip on the trimmer and keep bystanders at a safe distance. For optimal cutting performance, allow the trimmer line to reach full speed before engaging with vegetation. Avoid striking hard surfaces like concrete or rocks, as this can prematurely wear or break the trimmer line.

Maintenance
Regular maintenance ensures the best performance and extends the life of your trimmer and replacement spools. After each use, clean any grass clippings or debris from the trimmer head and cap. Inspect the trimmer line for wear and replace the spool when the line is depleted. Periodically check the cap cover for cracks or damage and replace if necessary to maintain proper line feeding.

Troubleshooting
- Line not feeding automatically: Ensure the spool is correctly seated and the cap cover is securely fastened. Check for any debris or tangled line within the trimmer head that might obstruct feeding.
- Line breaking frequently: This can occur if the line is hitting hard surfaces, if the line is worn, or if the trimmer head is operating at an incorrect angle. Ensure you are using the correct 0.065 inch diameter line. Inspect the line for any damage or weak points before use.
- Difficulty removing cap cover: If the cap cover is difficult to remove, ensure the trimmer is off and try pressing both release tabs simultaneously and firmly.
