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.

Claims (6)

1. A woodworking machine comprising:

a blade selected from a range of operable sizes;

a detection system adapted to detect a dangerous condition between a person and the blade;

a brake adapted to decelerate the blade in response to detection of the dangerous condition; and

a brake positioning system configured to allow the brake to be selectively positioned in at least two different operable positions to accommodate at least two different blade sizes;

where the brake positioning system is configured to prevent the brake from being positioned in an operable position that does not correspond to the size of the blade.
