Abstract
A saw is disclosed having a detection system adapted to detect a dangerous condition between a person and a saw blade, and a brake adapted to stop the saw blade in response to detection of the dangerous condition. The saw further includes a brake positioning system that allows the brake to be positioned in at least two different operable positions to accommodate at least two different blade diameters. The saw may include a system to detect brake-to-blade spacing.

7. A woodworking machine comprising:
-
a working portion adapted to work when moving;
a detection system adapted to detect a dangerous condition between a person and the working portion;
a reaction system associated with the detection system to cause a predetermined action to take place relative to the working portion upon detection of the dangerous condition, where the reaction system includes a component positioned adjacent the working portion; and
a positioning system adapted to allow the component to be positioned in more than one position adjacent the working portion to accommodate working portions of different sizes.
