Hi. I was wondering if I can get some pointers. I used it this weekend. Power it off like usually. Tonight it won't power on. I tired to find a manual but nothing. I am thinking about opening it up. I put a new battery in and still nothing. It is supposed to be dirt and water proof. I barely use the thing in 2 years. I use it for fixtures but I machine a lot of stuff on one fixture. Thank you.
