I wasn't sure where to post this. I'm having a hard time reaching Black and Decker and thought I'd ask here.

In July, I bought a Black and Decker cordless circular saw, just for small jobs. I actually didn't even put it together (the blade) until the other day, when I needed to use it. I tested it before using it and inside a slotted area of the saw, whenever I let up on the trigger (so it stops), I'm seeing a flash of light in there. Seems like that's not normal.......but I tend to notice lots of things that most people don't notice. (and I drive myself crazy). Is there any reason that flash of light when stopping the saw is normal?

Thanks!
