What is Kickback?

Kickback is the sudden, rearward motion of the saw that
can occur if the kickback zone of the bar touches an
object. Most kickbacks are small. They can cause the
bar tip to jump only a few inches and pose little danger.
However, a kickback can also be very powerful. If you
are not paying attention and/or have a poor grip, the saw
can be thrown all the way back at you. If the chain is
still running, and it hits you, it will severely cut you.
Rotational Kickback
Kickback can occur when the upper tip of the guide bar,
the kickback zone, touches something, such as a trunk,
branch or other object.
When the nose is used, only one or two cutters engage
the wood at a given time. As a result, the chain might
grab or jam. When the chain gets blocked and stops, the
reaction will cause the guide bar to kick back. It can be a
lightning fast, reverse action, kicking the guide bar back
at you.

WARNING
Kickback can be sudden
and violent, and may
throw the bar and saw
chain back at you,
inflicting serious or fatal
injury. A good
understanding of this
phenomenon and how it
can be avoided is a must
when working with a
chain saw.
