How to fix the trimmer head if it will not advance line on my Ego Power+ ST1510?
- B
  Brian PaceAug 14, 2025
  If the trimmer head on your Ego Power+ Trimmer won't advance the line, it could be due to a few reasons: * The motor shaft or trimmer head may be bound with grass. Stop the trimmer, remove the battery, and clean the motor shaft and trimmer head. * There might not be enough line on the spool, or the line is breaking at the eyelet. Remove the battery and replace the cutting line. * The line could be tangled. Remove the battery, remove the line from the trimmer head, and rewind it. * The line might be too short. Remove the battery and manually pull the lines while alternately pressing down and releasing the trimmer head.

  If the cutting line cannot be passed through the trimmer head when inserting the line on your Ego Power+ Trimmer, it could be due to: * The cutting line being split or bent at the end. Cut the worn end of the line and reinsert it. * The lower cover not being released to position after reinstalling. Attach the battery pack onto the trimmer and press the line loading button to briefly start the power loading to release the lower cover.

Why the cutting line cannot be wound into the trimmer head properly on my Ego Power+ ST1510?
- G
  gregory22Aug 21, 2025
  If the cutting line cannot be wound into the trimmer head properly on your Ego Power+ Trimmer, it could be due to: * The cutting line being too long. Cut the line so that about 5.5 inches (14cm) is showing on each side. * Improper cutting line being used. It is suggested to use EGO original nylon cutting line. * Grass debris or dirt accumulating in the trimmer head and blocking the movement of the line spool. Remove the battery, open the trimmer head, and clean it thoroughly. * The motor overheating 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. * Low battery. Charge the battery.

  If grass is wrapping around the trimmer head and motor housing of your Ego Power+ Trimmer, it's likely because you are cutting tall grass at ground level. To prevent this, cut tall grass from the top down, removing no more than 8 inches in each pass.

  If the blade on your Ego Power+ Trimmer is not cutting the line, it's likely that the line-cutting blade on the edge of the guard has become dull. Sharpen the line-cutting blade with a file or replace it with a new blade.
