Introduction
This guide shows you how to replace a faulty spindle lock assembly. The symptoms of a faulty or clogged spindle lock assembly are failure to stop blade rotation in less than one full rotation, or if the spindle lock does not allow the blade to rotate freely when released (binding). For more information check our troubleshooting guide. Before getting started, remove the inner flange bushing, cut depth lever, and upper housing by following the Inner Flange Bushing Guide and steps 1-5 in the Switch Assembly Guide.
