I don't actually know the correct answer John.
Here is what I suspect by looking at the picture.
From the picture it appears the pointer is set to test.
The switch probably needs to be set to auto.

I posted some photos in ABPW... In the photos it can be seen that there
are adjustment wheels in the switch. What do they do and how does one
judge that the adjustments are correct?

This problem first occurred back in June while I was building a patrol
box for my sons' Boy Scout Troop. I was away for a couple months this
summer and had forgotten about the problem until I used the saw today...

Thoughts?

Thanks,
