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 ANSI B175.1 when tested on a representative sample of chain
saws.
Normal Cutting Position
-
Those positions assumed in performing the bucking
and felling cuts.
Notching Undercut - A notch cut in a tree that directs the tree's fall.

reduce kickback significantly.
Replacement Saw Chain

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
