Kickback is what most people dread when using a chainsaw. It is responsible for the majority of chainsaw injuries and even deaths.
Rotational Kickback: The rapid upward and backward motion of the saw that 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.
Linear kickback (also called pinch kickback): The rapid push back of the saw that can occur when the wood closes in and pinches the moving saw chain in the cut along the top of the guide bar.Saws under 3.8 cubic inch (62cc)
Effects of the ANSI standard on saw chain:
When replacing chain on saws below 3.8 cubic inch (62cc), any Carlton chain with the proper pitch and gauge which is designated as low-kickback can be used.
Effects of the ANSI standard on guide bars:
When replacing guide bars, a Carlton branded guide bar with the same bar length, nose radius (same number of sprocket teeth) and pitch can be used to maintain the low-kickback performance.
Saws 3.8 cubic inch (62cc) and larger
Effects of the ANSI standard on saw chain:
When replacing chain on saws 3.8 cubic inch (62cc) and larger, the saws may, but are not required to, meet the low-kickback acceptance criteria. Users should use this class of saws with specialized training in dealing with kickback.
