Kickback is the term to describe the unexpected upward motion of the guide bar. Kickback – the rapid upward motion ofh te guide bar that can occur when the saw chain, near the nose of the top area of the guide bar, contacts an object such as a log or branch, or the backwardm otion that can occur when the wood closes in and pinches hte saw chain in the cut. 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.
‘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.
The reason it has this name is that the chainsaw tip is the most common part of the chainsaw that can cause a kickback. If you’re cutting with a chainsaw and the wood closes around the chain tightly, it can cause a chainsaw kickback to occur. Chainsaw kickback is the most common type of chainsaw injury that people encouter.
Below, we’ll explain chainsaw kickback as well as the kickback zone, causes of kickback, preventive measures, and how to avoid kickbacks in the first place altogether. Chainsaw chaps are preferable because they are chainsaw resistant and are also specially designed to protect the left side of your leg, which is another prime target for a kickback. There are many ways to avoid a potential chainsaw kickback.

The two main causes of injury from kickback is trauma from the wood striking the head, chest, or torso of the woodworker, or the wood moving so quickly that an operator doesn’t have time to take their hand off of it and it gets pulled across the saw blade.
Should you run a chainsaw at full throttle?
Engine Protection Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised.
How do I stop my chainsaw from pinching?
To stop your chainsaw from getting stuck, make a cut on top of the log or tree that’s preferably one-third of the log’s diameter. Use your chainsaw to cut from the underside until you meet the initial top cut. Always stand on the side when cross-cutting to prevent injury.
Would a chainsaw cut through bone?
Bones may be slightly tougher, but they are rigid and a chainsaw will likely be able to cut through them without much problem – though it will probably dull the blade more than wood.
Where do most chainsaw injuries occur?

Do you need anti-kickback pawls?
It should go without saying that no one safety device can make a saw 100% safe. While anti-kickback pawls will reduce your risk of injury or equipment damage do not neglect to act carefully and to use other safety equipment.
Can kickback occur with a riving knife?
Blades with a narrow kerf relative to their body are more susceptible to grabbing and kickback. A riving knife has these advantages over a splitter: It does not need to be removed from the saw when cross-cutting or doing a blind (non-through) cut as it does not extend above the top of the saw blade.
Do Anti-kickback pawls work?
The farther back from the rear of the blade, the less effective it is. Anti-kickback pawls should be the backup to the preceding two options – if you can’t, or don’t (despite your best efforts) prevent the kickback, the pawls will at least retard the return of the stock in your direction.
Do you need to break in a chainsaw?
Typically we recommend a break in period of 6-10 tanks of fuel. During this period the engine should not be allowed to run at high RPMs for extended periods of time.
Can you cut with the top of a chainsaw?
While it’s designed to cut with either the top or bottom of the blade, just about anything that comes in contact with the top half of the end tip of the blade (known as the kickback zone) can change the cutting momentum and cause the saw to slam back against you.
