Front Handle The support handle located at or toward the front of the chain saw. This handle is for the left hand. Guide Bar A solid railed structure that supports and guides the saw chain.

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.
