While performing a miter cut the sanding drum damagerd the power cable to the contol cut feature on my sears radial arm. I repaired the cord but the control cut motor no longer works. I have figured out how to get the covers off around the motor but not how to get into the motor itself to see if I can see the problem. What I would like to do is DISABLE the feature - either by figuring out how to disconnect the cable or any other way that anyone may know. The sears manual that comes wit the saw is no help. Any ideas on how to do this or how to get a more in depth manual?
