Front Handle Guard - A structural barrier between the front handle of a chain saw and the guide bar, typically located close t o the hand position on the front handle and sometimes employed as an activating lever for a chain brake.

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 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. Oiler Control - A system for oiling the guide bar and saw chain.

Rear Handle - The support handle located at or toward the rear of the saw.

Reduced Kickback Guide Bar - A guide bar which has been demonstrated to reduce kickback significantly.

Replacement Saw Chain - A chain that complies with the kickback performance requirements of ANSI 8175.1 when tested with specific chain saws. 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.

Spiked Bumper (Spike) - The pointed tooth or teeth for use when felling or bucking to pivot the saw and maintain position while sawing.

Switch - A device that when operated will complete or interrupt an electrical power circuit t o the motor of the chain saw.

Lock-OffButton - A movable stop that prevents the unintentional operation of the switch until manually actuated.
