Stanley - For model number LSTE525
September 6, 2023
Automatic string feed not feeding line. Spool cap, lever, and new spool all appear to be in good condition and not damaged. The puch button switch does cause the trimmer to abruptly stop spinning. I need help.
Chris Boyle Profile
Hello Stanley, thank you for reaching out. Based on the description you have provided, we would recommend you check the spring, part number PS12510006, to fix the issue. If the spring is broken, the spool will just stay on the head. Glad to be of assistance!
