What is kickback ?

STOP 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 an electric saw.

Kickback is the sudden, rearward jerk 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 reaction kicking the guide bar back at you.
