Blade fell in container on opening!,I managed to (after cleaning out ) remove by detaching large circular plate on top of container turning anticlockwise there's a little arrow on it that lines up with a dot on body , I found bracket snapped of which had 3 posts on it with 3 screws holding it underside of plate, I removed screws ,holding broken bracket in line where it had snapped off I drilled through right circular plate, got some longer counter sunk screws and nuts and bolted from top ( after countersinking top plate) finished " just on time" !!
