Why do chainsaws kick back so violently?

 

Are you a professional or a hobbyist who uses a chainsaw regularly? If so, you are probably well aware of the dangers of operating this powerful tool. One of the most dangerous aspects of using a chainsaw is the potential for it to kick back, which can cause serious injury or even death. In this blog post, we will explore the reasons why chainsaws kick back and what can be done to prevent this dangerous phenomenon.

Understanding Kickback

First, let's define what we mean by kickback. Kickback occurs when the tip of the chainsaw's guide bar comes into contact with an object, such as a branch or a tree trunk. This contact causes the saw to rotate rapidly and violently, often causing the operator to lose control of the tool. Kickback can also occur when the saw's chain becomes jammed or pinched, causing the saw to twist and move unexpectedly.

Reasons for Kickback

There are several reasons why chainsaws kick back. One of the most common reasons is due to an incorrect angle of the guide bar. When the guide bar is not parallel to the ground, it can cause the saw to twist and rotate, increasing the risk of kickback. Additionally, using a dull or worn-out chain can also increase the risk of kickback, as a dull chain may become jammed or pinched more easily.

Another reason for a kickback is when the operator does not use the proper technique when cutting. This includes using the saw to cut through material that is too thick for its capabilities, using the saw to cut at a steep angle, or using the saw to cut at an angle that is not parallel to the ground.

Preventing Kickback

To prevent kickback, it is essential to use the proper technique when cutting with a Stihl chainsaw kickback guard. This includes holding the saw with both hands, keeping a firm grip on the saw, and keeping the guide bar parallel to the ground. Additionally, it is important to use a sharp and well-maintained chain, as a dull or worn-out chain can increase the risk of kickback.

It is also important to use a chainsaw with a low kickback chain. Low kickback chains have been designed to reduce the risk of kickback by using a different tooth geometry. They also have a reduced nose radius, which means that the tip of the guide bar is less likely to make contact with an object.

Safety first

It is also very important to always wear appropriate personal protective equipment when using a Stihl chainsaw safety bar position. This includes safety goggles, ear protection, and heavy-duty gloves. It is also important to be aware of your surroundings and use the chainsaw cautiously.

In conclusion, kickback is a dangerous phenomenon that can occur when using a chainsaw. It is caused by a variety of factors, including an incorrect angle of the guide bar, a dull or worn-out chain, and improper technique when cutting. To prevent kickback, it is essential to use the proper technique when cutting, maintain a sharp and well-maintained chain, and use a chainsaw with a low kickback chain. Remember to always use the chainsaw with caution, be aware of your surroundings, and wear appropriate personal protective equipment. By following these guidelines, you can greatly reduce the risk of kickback and make your chainsaw usage a safe and enjoyable experience.
