    What to do if automatic line feed does not feed more line in Craftsman 98020?

      Melissa TaylorAug 7, 2025
      If the automatic line feed on your Craftsman Trimmer isn't feeding more line, consider the following: First, check the spool to see if the line is wound correctly; it should not be crisscrossed. If it is, unwind and rewind it neatly. Inspect the spool for any damage and replace it if necessary. Ensure enough line remains on the spool. The cutting line should protrude approximately 4-13/16 inches (122mm) from the spool. Finally, if the cutting line is too long, trim it, so it just reaches the trimming blade.

    Why Craftsman Trimmer battery won't charge?
    • K
      Kevin WatsonAug 13, 2025
      There are several reasons why your Craftsman Trimmer battery might not be charging. First, ensure the battery is correctly inserted into the charger until the green LED appears. If the battery is totally drained, allow it to charge for up to 8 hours. Also, verify that the charger is plugged into a working outlet. Finally, the surrounding air temperature could be too hot or too cold; move the charger and tool to a location where the air temperature is between 40°F (4.5°C) and 105°F (40.5°C).

      If your Craftsman Trimmer is overfeeding, it might be because you're holding it at too sharp of an angle. Make sure you are not exceeding a 10° angle.
