With the top gone, the tree is ready to cut into sections. This looks hazardous and is. Kevin has the chainsaw directly in front of his head. If it jumped at him...notice, though, that he keeps himself to the side and cuts at the base of the bar, reducing the risk of a kickback. He also wears safety headgear and puts the saw into idle when the cut is almost complete, so the chain does not turn. At this moment he still has a hinge of wood on the far side of the cut. With the saw idling and held in his right hand he pushes the section over with his left hand and the weight of the section breaks the hinge and the momentum of the section carries it away from the tree.
