Why won't my EGO ST1620T Trimmer start?
- G
  Gerald HardyJul 28, 2025
  If your EGO Trimmer isn't starting, several factors could be at play. First, ensure the battery pack is properly attached. If it is, remove the battery, inspect the contacts, and then re-install it to ensure a solid connection. A depleted battery can also cause this issue, so charge the battery pack fully. Make sure that you move the lock-off switch forward before depressing the variable speed trigger. Lastly, check the motor shaft and trimmer head for any grass obstructions, and remove them if present.

How to fix the cutting line if it cannot be wound into the EGO ST1620T Trimmer head properly?
- C
  cookmadisonAug 1, 2025
  If the cutting line can't be properly wound into the EGO Trimmer head, ensure you're using the recommended EGO original nylon cutting line. Debris accumulation can obstruct the line spool's movement; remove the battery, open the trimmer head, and clean it thoroughly. Also, the motor may be overheated due to repeatedly operating the line winding system, so let the string trimmer work under no load for a few minutes to cool the motor, then try to reload the line. A low battery capacity can cause this issue as well, so charge the battery. Ensure the line is wound into the spool assembly by pulling it out and reinserting it.

What to do if my EGO Trimmer stops while cutting?
- J
  James ParkerAug 10, 2025
  Your EGO Trimmer might stop during operation due to several reasons. Check if the guard is properly mounted; an unmounted guard can lead to an overly long cutting line and motor overload. Using the recommended nylon cutting line with a diameter of 0.095 in. (2.4 mm) is also important. Overheating can cause the trimmer to stop, so allow the battery pack or string trimmer to cool down. Also, make sure that the battery pack is correctly installed and charged.

Why is my EGO Trimmer head not advancing line?
- J
  james15Aug 13, 2025
  If the trimmer head on your EGO Trimmer isn't advancing the line, the motor shaft or trimmer head might be bound with grass. Stop the trimmer, remove the battery, and clean these components. Also, make sure that there is enough line on the spool. If the line is tangled, remove the battery, then remove the line from the trimmer head and rewind it. If the line is too short, remove the battery and pull the lines manually while alternately pressing down and releasing the trimmer head. Using the recommended nylon cutting line with a diameter of 0.095 in. (2.4 mm) is also important.

How to prevent grass from wrapping around the EGO Trimmer head?
- L
  lcoxAug 18, 2025
  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 tall grass from the top down, removing no more than 8 inches in each pass.

What to do if the blade is not cutting the line on my EGO ST1620T?
- K
  Karen LopezAug 22, 2025
  If the blade on your EGO Trimmer isn't 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.
