      Your EGO Trimmer might not start for several reasons. First, ensure the battery pack is properly attached. If it is, remove the battery and check for any obstructions or damage to the contacts, then re-install it. Also, the battery pack may be depleted and needs charging. Finally, make sure you are pressing down the lock-off button and holding it while depressing the switch trigger simultaneously.

    Why can't I wind the cutting line into my EGO ST1520 head?
    • A
      Amy JenkinsAug 23, 2025
      If the cutting line cannot be wound into the trimmer head properly on your EGO Trimmer, consider the following: * The cutting line might be too long. Cut the line so that about 5.5 inches (14cm) is showing on each side. * You might be using an improper cutting line. It is suggested that you use EGO original nylon cutting line. * Grass debris or dirt may have accumulated in the trimmer head, blocking the movement of the line spool. Remove the battery, open the trimmer head, and clean it thoroughly. * The motor might be overheated due to repeatedly operating the line winding system. Let the string trimmer work under no load for a few minutes to cool the motor, then try to reload the line. * The battery could be low. Charge the battery.

    How to fix an EGO Trimmer head that won't advance line?
    • D
      dmayAug 26, 2025
      If your EGO Trimmer head won't advance the line, it could be due to a few reasons. First, the motor shaft or trimmer head might be bound with grass; stop the trimmer, remove the battery, and clean them. Alternatively, there might not be enough line on the spool, or the line is breaking at the eyelet. In this case, remove the battery and replace the cutting line. Also, the line could be tangled; remove the battery, take out the line, and rewind it. Lastly, the line might be too short; remove the battery and manually pull the lines while pressing down and releasing the trimmer head.

      If the cutting line isn't winding properly into your EGO Trimmer head, several factors could be at play. The cutting line might be too long; cut it so about 5.5 in. (14cm) is showing on each side. Alternatively, you might be using an improper cutting line. Grass debris or dirt could have accumulated in the trimmer head, blocking the line spool's movement; remove the battery, open the trimmer head, and clean it thoroughly. The motor might be overheated due to repeatedly operating the line winding system; let the trimmer work under no load for a few minutes to cool the motor, then try to reload the line.

    What to do if the cutting line cannot be passed through the EGO ST1520 head?
    • S

      If the cutting line cannot be passed through the trimmer head when inserting the line, it may be because the cutting line is split or bent at the end. Cut the worn end of the line and reinsert it. Another reason may be that the lower cover is not released to position after reinstalling. Attach the battery pack onto the trimmer; press the line loading button to briefly start the power loading to release the lower cover.

    How to prevent grass from wrapping around my EGO ST1520 head?
    • F
      fryfrancesSep 6, 2025
      To prevent grass from wrapping around your EGO Trimmer head and motor housing, avoid cutting tall grass at ground level. Instead, cut tall grass from the top down, removing no more than 8 inches in each pass.

    Why is the blade on my EGO Trimmer not cutting the line?
    • R
      Ricky ReynoldsSep 8, 2025
      If the blade on your EGO Trimmer is not cutting the line, the line-cutting blade on the edge of the guard may have become dull. Sharpen the line-cutting blade with a file or replace it with a new blade.

    What causes cracks on the EGO Trimmer head?
    • L
      lrichmondSep 12, 2025
      Cracks on the trimmer head or a loose spool retainer can be caused by a worn-out trimmer head. Also, the nut that locks the trimmer head can be loose; open the trimmer head and use an impact wrench to tighten the nut.
