What to do if Kobalt KST 224B-03 Trimmer stops while cutting?

  If your Kobalt Trimmer stops while cutting, several factors could be at play. First, the motor shaft or cutting head may be bound with grass. To resolve this, stop the trimmer, disconnect the battery, and remove any grass from the motor shaft and cutting head. Alternatively, the motor could be overloaded. Try moving the cutting head to cut grass no more than 8 inches in a single pass, then remove the cutting head from the grass and restart the tool. Finally, the battery pack or trimmer may be too hot. In this case, release the trigger switch, allow the tool to cool down, and then try starting it again.

Why Kobalt KST 224B-03 cutting head will not advance the cutting line?
- M
  Mary HebertAug 21, 2025
  If the cutting head of your Kobalt Trimmer won't advance the cutting line, it could be due to a couple of reasons. One possibility is that the motor shaft or cutting head is bound with grass. You should stop the trimmer, disconnect the battery, and clean the motor shaft and cutting head. Another reason might be that there isn't enough cutting line on the spool. In this case, disconnect the battery and replace the cutting line.
