‘Chainsaw kickback’ is a phrase that is used when discussing operating chainsaws. To ensure absolute safety, it is extremely important to ensure you’re well versed in what it means and how to handle it. To fully prepare for chainsaw kickback you first need to understand what it is, how it happens and how to avoid it.
Kickback is the term to describe the unexpected upward motion of the guide bar.

The most common and probably most violent kickback occurs when contact is made, either accidentally or intentionally, in this “Kickback zone.” In some cases the blade tip may move upward and back toward the operator who could suffer a very serious or fatal injury.
Kickback happens when the chain’s rotational energy gets thrown back at you, and you lose control of the saw. LINEAR KICKBACK. If the chain gets pinched on either side by the wood being cut, the whole saw can get pushed back at you, full speed. PULL-IN KICKBACK. If your saw hits a branch on the other end of the wood, or even a nail, it can yank the saw forward and away from you.
