Hi, I have a Ryobi 18V circular saw RWSL1801 with a peculiar fault. I hope someone can help. It runs for a couple of seconds then cuts out. Both the rotation and the laser stop. It re-starts again perfectly easily when you re-press the trigger. The motor and blade rotate freely by hand, it isn't jammed. My thought is that there is an over-current trip somewhere, possibly in the battery pack, but can't see any buttons. Can anyone help? Thanks Paul
