The saw handle's switch can fail, causing the saw to smoke, spark, and trip circuit breakers, and disable the safety brake. The saw also can keep operating unless the unit is unplugged, posing a laceration hazard to consumers.
The aluminum cast pivot joint that connects the base of the saw to the head assembly (which contains the saw blade) can crack under extreme pressure or force, causing the blade assembly to unexpectedly break free from the stationary base. This poses a laceration hazard to consumers.
