This machine is surprisingly good. It cuts well. But there is something very strange about it: the blade rotates 'backwards', IE it spins opposite to any grinder I have EVER experienced. As a result, it always has to potential to kick-back towards you, and makes it EXTREMELY dangerous and hard to use if you are doing wall cuts.
Luckily, I managed to dismantle the motor from the gearbox, and rotate it 180 degrees, so it now spins in the normal, safe direction. I also moved one of the water jets to the other side of the guard, and rigged it up to attach to a garden hose and inline tap.
