Mark Mandell - Gone Round In New Jersey
Have a Makita LS 1211 slider.
Switch has gotten sticky so tapped lightly to get it to click off.
Apparently that light tap flexed the plastic safety shield just enough for the blade to grab it. Boom! Plastic shrapnel went flying across the shop.
Blade's OK as am I.
Order parts on line. I've blown out the switch several times so it's time for a new switch.
