I tried using my 360i today and when I went to squeezing the trigger to spin the head, nothing happened...of course, I replugged it in another outlet and nothing happened again. So, I made a quick observation to see if anything out of the norm was visible,saw nothing. Basically when you try to trigger the power on it only spins for half a second...it kept doing this over and over every time I squeezed the trigger. What do you think might be the problem? Thanks.
