Mr

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
