How to troubleshoot starting issues with my EGO ST1500SF Trimmer?

B
Becky FloresAug 15, 2025
If your EGO Trimmer fails to start, there are several potential causes. First, make sure the battery pack is correctly attached to the trimmer. If it is, remove the battery and check for any obstructions or issues with the contacts before reinstalling it. A depleted battery pack is a common reason; ensure it's adequately charged. Finally, the trimmer requires simultaneous depression of the lock-off lever and the trigger to start. Press the lock-off lever, hold it, and then depress the trigger.

What to do if the EGO ST1500SF Trimmer head won't advance line?

If the trimmer head on your EGO Trimmer won't advance the line, start by stopping the trimmer, removing the battery, and cleaning any grass or debris from the motor shaft and trimmer head. If that doesn't work, the spool may be low on line, necessitating a replacement. Also, a dirty trimmer head can cause issues, so clean the spool, spool retainer, and spool base. If the line is tangled on the spool, remove the battery, take the line off the spool, and rewind it. Lastly, if the line is too short, remove the battery and manually pull the lines while alternately pressing down and releasing the trimmer head.
