can occur when the wood closes in and pinches the moving
saw chain in the cut along the top of the guidebar.

contacts an object, such as a log orbranch.
• Limbing ‑ Removing the branches from a fallentree.
• Low‑Kickback Chain ‑ A chain that complies with the
kickback performance requirements of ANSI B175.1–2012
(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
