Hello MGlen.
Thank you for your feedback. We understand how frustrating it can be when string feed performance is inconsistent, especially during edging where steady line advancement is important. For the 60V 16" Gen2 String Trimmer (SKU 2122802), frequent line breakage and the need for multiple bumps can often be related to line type, installation, or cutting conditions. We recommend ensuring the line is properly loaded and evenly wound in the head without overlap, as uneven winding can restrict smooth feed. If you are still using the preloaded line, you may want to try a high-quality 0.080" or 0.095" line, as thicker or more durable line can reduce breakage depending on the application. Also, avoid cutting directly against hard surfaces like concrete or fencing, as this can cause rapid wear and snapping. When bump feeding, a firm tap on a hard surface (rather than grass) typically provides more consistent line advancement.
You may also find it helpful to review Greenworks instructional videos on the Greenworks Tools YouTube channel for proper line loading and trimmer head operation. If the issue continues after trying these steps, we recommend reaching back out to Greenworks support so they can review your case further and assist with next steps or potential service options. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.
