Chainsaw Names and Terms

Bucking: The process of cross cutting a felled tree or log
into lengths.
Chain brake: A device used to stop the chainsaw.
Chainsaw powerhead: A chainsaw without the saw chain
and guide bar.
Clutch: A mechanism for connecting and disconnecting a
driven member to and from a rotating source of power.
Drive sprocket or sprocket: The toothed part that drives
the saw chain.
Felling: The process of cutting down a tree.
Felling back cut: The final cut in a tree felling operation
made on the opposite side of the tree from the
notching cut.
guide bar: A solid railed structure that supports and guides
the saw chain.
Kickback: The backward or upward motion, or both of the
guide bar occurring when the saw chain near the nose of
the top area of the guide bar contacts any object such as a

log or branch, or when the wood closes in and pinches the
saw chain in the cut.
Kickback, pinch: The rapid pushback of the saw which can
occur when the wood closes in and pinches the moving
saw chain in the cut along the top of the guide bar.
Kickback, rotational: The rapid upward and backward
motion of the saw which can occur when the moving saw
chain near the upper portion of the tip of the guide bar
contacts an object, such as a log or branch.
low-kickback chain: A chain that complies with the
kickback performance requirements of ISO 9518: 1998
(when tested on a representative sample of chainsaws.)
normal cutting position: Those positions assumed in
performing the bucking and felling cuts.
Reduced kickback guide bar: A guide bar which has been
demonstrated to reduce kickback significantly.
Replacement saw chain: A chain that complies with
kickback performance requirements of ISO 9518: 1998 when
tested with specific chainsaws. It may not meet the ANSI
performance requirements when used with other saws.
saw chain: A loop of chain having cutting teeth, that cut
the wood and that is driven by the motor and is supported
by the guide bar.
switch: A device that when operated will complete or
interrupt an electrical power circuit to the motor of the
chainsaw.
switch linkage: The mechanism that transmits motion
from a trigger to the switch.
