About 30 minutes, I was cutting some wood when my hair got sucked into the saw's motor, pulling my face into the piece and giving me a bloody nose. I couldn't pull the saw out like then, so I carried the entire piece to my tool rack to cut the hair off with scissors.
Without the description it took me a minute to figure out where the hair was. You don't normally think of the fan portion of the motor as a pinch point, but if something can get in there it gets bad.
Ryobis are a bit bad for this, eg: the one-handed blower has the intake on the left, meaning any right-handed person wearing a jacket is gonna get their flaps sucked.
