Chainsaw kickback is a term that frequently comes up when discussing chainsaw safety. This potentially dangerous event occurs when a chainsaw’s cutting chain suddenly stops or is abruptly forced backward, causing the saw to violently jerk in the user’s hands.
Understanding chainsaw kickback and knowing how to prevent it is essential for both novice and experienced users. In this blog post, we will explore what is chainsaw kickback? the causes of chainsaw kickback, discuss safety precautions, and provide tips for reducing the risk of this hazardous occurrence.
Understanding Chainsaw Kickback
Chainsaw kickback occurs when the saw’s cutting chain suddenly stops or is violently forced backward, causing the saw to abruptly and uncontrollably jerk in the user’s hands. This rapid movement can result in the chainsaw striking the operator, potentially causing severe injuries or fatalities. Two primary factors contribute to chainsaw kickback: pinching the bar and contact with the upper tip of the bar.
Pinching the Bar
When cutting with a chainsaw, the wood being cut can sometimes close in and pinch the top part of the chainsaw bar. This pinching action can cause the chain to stop or slow down suddenly, leading to a rapid and uncontrolled motion of the chainsaw.
Contact with the Upper Tip of the Bar
The upper quadrant of the chainsaw bar’s tip is known as the “kickback zone.” When the kickback zone comes into contact with an object while cutting, the chain may come to an abrupt halt or even reverse its direction, causing the saw to kick back towards the user.
Causes of Chainsaw Kickback
There are several factors that can contribute to chainsaw kickback:
Nose Contact
The most common cause of kickback is when the upper tip or nose of the chainsaw bar comes into contact with a solid object while cutting, such as a log, branch, or another part of the tree.
Pinching the Chain
Kickback can also occur when the chain becomes pinched or caught between the wood being cut. This can happen if the tree or branch being cut closes in on the chain, causing it to become stuck and forcing the saw back towards the operator.
Cutting with the Tip
Using the tip of the chainsaw bar to make a cut, rather than the full length of the chain, can increase the risk of kickback. This is because the chain’s rotational force is concentrated at the tip, which makes it more likely to catch and jerk the saw.
Incorrect Chain Tension
A loose or improperly tensioned chain can cause it to catch on the wood or slip off the bar, leading to kickback.
Dull or Damaged Chain
A dull or damaged chain can make it more difficult to control the chainsaw and increases the likelihood of kickback. Regularly inspect and maintain your chain to ensure it is sharp and in good condition.
Improper Body Position
Standing too close to the chainsaw or not holding it with a firm grip can increase the risk of losing control during a kickback.
Incorrect Cutting Techniques
Using improper cutting techniques, such as plunge cuts or ripping, can increase the risk of kickback.
To minimize the risk of chainsaw kickback, it’s important to follow proper safety procedures, maintain your chainsaw, and use the appropriate cutting techniques. Always wear appropriate personal protective equipment (PPE) and be aware of your surroundings while operating a chainsaw.
Types of Chainsaw Kickback
Chainsaw kickback is a dangerous and sudden reaction that can occur during chainsaw operation. It typically happens when the tip of the chainsaw bar comes into contact with an object, causing the saw to jerk violently back towards the operator. This can lead to severe injuries or even fatalities if not handled properly. There are two main types of chainsaw kickback:
Rotational Kickback
Rotational kickback is the most common and dangerous type of chainsaw kickback. It occurs when the upper quadrant of the chainsaw bar’s tip, known as the “kickback zone” or “danger zone,” makes contact with an object like a log or branch.
When this happens, the chain’s cutting teeth can dig into the object, causing the saw to rotate rapidly upward and backward around the cutting axis in the direction of the operator. This sudden, forceful motion can be difficult to control, and it can result in severe injuries if the operator is not prepared or using proper safety equipment.
To minimize the risk of rotational kickback, follow these safety precautions:
- Always be aware of the bar’s tip and avoid contact with objects while cutting.
- Hold the chainsaw firmly with both hands, maintaining a secure grip.
- Use a chainsaw with a chain brake, which is designed to stop the chain in case of a kickback.
- Maintain proper body positioning and footing while operating the chainsaw.
- Keep the chain sharp and well-maintained to prevent it from getting stuck in the material being cut.
Linear Kickback
Linear kickback occurs when the chainsaw’s chain gets pinched or caught in the material being cut, forcing the saw to be pushed straight back towards the operator. This type of kickback is less common and generally less severe than rotational kickback but can still cause injuries if the operator is not prepared.
To minimize the risk of linear kickback, follow these safety precautions:
- Ensure proper tension on the chain to prevent it from getting stuck or pinched.
- Use proper cutting techniques and avoid cutting with the bottom of the bar or forcing the saw through the material.
- Be aware of potential pinch points or obstacles in the cutting path.
- Keep the chain sharp and well-maintained to allow for smooth and efficient cutting.
By following these safety measures and using proper cutting techniques, you can significantly reduce the risk of chainsaw kickback and ensure a safer working environment.
How to Prepare for Chainsaw Kickback?
Preparing for chainsaw kickback involves understanding the risks, using proper safety equipment, and employing the right cutting techniques. By taking these precautions, you can minimize the chances of kickback and protect yourself in case it occurs. Here are some steps to prepare for chainsaw kickback:
Understand the Risks
Familiarize yourself with the common causes of chainsaw kickback, such as contacting the “kickback zone” or “danger zone” on the tip of the bar, or getting the chain pinched or caught in the material being cut. Being aware of these risks can help you avoid situations that may lead to kickback.
Use a Chainsaw with Safety Features
Choose a chainsaw that has built-in safety features, such as a chain brake and a low-kickback chain. A chain brake can stop the chain instantly when a kickback occurs, while a low-kickback chain has a design that reduces the likelihood of kickback.
Wear proper personal protective equipment (PPE): Protect yourself by wearing appropriate safety gear, including:
Chainsaw Chaps or Pants
These are made from cut-resistant material and can protect your legs from injury in case of kickback.
Safety Boots with Steel Toes
These provide added protection for your feet and improve your footing while working with a chainsaw.
Gloves with Cut-resistant Material
Gloves can help maintain a secure grip on the chainsaw and protect your hands from injury.
Eye Protection
Safety glasses or goggles can protect your eyes from flying debris or wood chips.
Hearing Protection
Earplugs or earmuffs can help protect your ears from the loud noise generated by the chainsaw.
