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?
- R

  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.

  If your EGO Trimmer fails to start, here's what to check: 1. **Check Cable Connections:** Open the motor housing and ensure that all cables are securely connected to the motor. 2. **Motor Condition:** If the cables are properly connected, inspect the motor. If you suspect the motor is burned, test with a new motor. 3. **PCBA Functionality:** If the cables are well connected and the motor appears functional, the PCBA in the rear housing might be broken. Replace the PCBA.

  If your EGO Trimmer line isn't feeding correctly, the issue might be the cutting line itself. Try replacing it with a new cutting line, such as a 2.4mm nylon line.

How to prevent grass from wrapping around my EGO ST1500SF Trimmer head?

  To prevent grass from wrapping around the trimmer head and motor housing of your EGO Trimmer, avoid cutting tall grass at ground level. Instead, cut from the top down, removing no more than 8 inches in each pass.

Why is the blade on my EGO ST1500SF not cutting the line?
- D
  Dana BakerSep 12, 2025
  If the line-cutting blade on your EGO Trimmer isn't cutting the line effectively, it's likely that the blade on the edge of the guard has become dull. Sharpen the blade with a file or replace it with a new one.
