What should I do if the blade does not stop within 6 seconds after releasing the trigger?

If the blade doesn't stop within 6 seconds, unplug the saw immediately and consult the Troubleshooting Guide section. Possible causes include motor brushes that are not sealed or are sticking, an overheated motor brake, a loose arbor bolt, or cracked/damaged brushes. Corrective actions include inspecting, cleaning, or replacing the brushes, or contacting a Sears Service Center. (Page 20, 24)
