What should I do if the blade doesn't stop within 6 seconds after releasing the trigger?
If the blade doesn't stop within 6 seconds, unplug the saw and follow the instructions in the troubleshooting guide section. According to the troubleshooting guide, possible causes include motor brushes not sealed, motor brake overheating, a loose arbor bolt, or damaged brushes.
