Bucking
	Bucking is cutting a felled tree or log into lengths. How you should
	cut depends on how the log is supported. Use a saw horse
	(figure W) whenever possible.
	Always start a cut with the chain running at full speed and the
	ribbed bumper (7) in contact with the wood. To complete the cut
•	use a pivoting action of the ribbed bumper against the wood.
