In this article, we will explore some practical tips and techniques to help you stay safe and minimize the risk of kickback while cutting with a chainsaw. With these simple precautions, you can confidently take on any cutting task without compromising your safety.
Understanding Kickback
Definition of Kickback
Kickback is a term used to describe the sudden and powerful upward movement of the chainsaw’s bar and chain toward the operator. It occurs when the chain on the top of the bar makes contact with an object, causing the chain to stop suddenly while the motor and the bottom part of the bar continue to rotate. This reaction can be extremely dangerous and lead to severe injuries or even fatalities if not adequately addressed.
Causes of Kickback
Kickback is typically caused by a combination of factors, including the design of the chainsaw, the cutting techniques used, and the conditions in which the chainsaw is being operated. One of the main causes of kickback is improper contact between the chain and an object, such as a log or branch. Other factors contributing to kickback include using a worn-out or improperly tensioned chain, cutting with the bar’s tip instead of the bottom, or using excessive force while cutting.
Dangers of Kickback
Kickback poses a significant risk to the operator of the chainsaw. The sudden and powerful movement of the chainsaw can cause the operator to lose control, leading to severe injuries. The most common injuries associated with kickback include cuts, lacerations, amputations, and head or spinal injuries. It is crucial to understand the dangers of kickback and take the necessary precautions to prevent it.
Choosing the Right Chainsaw
Consider Bar Length
When choosing a chainsaw, one of the crucial factors to consider is the bar length. The bar length determines the maximum wood diameter that can be cut with the chainsaw. It is recommended to select a chainsaw with a bar length that matches your cutting needs. A longer bar length may be necessary for cutting larger logs, while a shorter one can provide more maneuverability in tight spaces.
Look for Safety Features
To ensure your safety while operating a chainsaw, it is essential to choose a model with proper safety features. Look for chainsaws that have a chain brake, which is designed to stop the chain’s rotation immediately if kickback occurs. Additionally, some models may have anti-vibration features to reduce operator fatigue and a throttle lockout to prevent accidental activation.
Evaluate Power and Performance
Consider the power and performance of the chainsaw before making a purchase. A chainsaw with sufficient power will allow you to tackle different cutting tasks more efficiently. It is recommended to choose a chainsaw that matches the intensity and frequency of your cutting needs. Assess the engine power, RPM (Revolution Per Minute), and other performance indicators to ensure you select a chainsaw that can handle the demands of your projects.
Wearing Proper Safety Gear
Protective Clothing
When operating a chainsaw, wearing the appropriate protective clothing is imperative for your safety. Start by wearing a long-sleeved shirt and long pants made of durable, cut-resistant materials, such as Kevlar or chainsaw chaps. These materials provide an extra layer of protection against accidental contact with the chainsaw’s blade. Avoid loose-fitting clothing that may get caught in the machinery and cause accidents.
Safety Glasses and Hearing Protection
Protecting your eyes and ears is vital when using a chainsaw. Always wear safety glasses or goggles to shield your eyes from flying debris, wood chips, and sawdust. These particles can cause severe eye injuries when they come in contact with the eyes.

Investing in high-quality chainsaw chaps or pants that meet safety standards and fit properly to ensure maximum protection is crucial.
Maintaining Proper Chain Tension
Checking Chain Tension
Proper tension in your chainsaw’s chain is essential for safe and effective cutting. To check the chain tension, turn off the chainsaw and use a gloved hand to pull the chain away from the bar. The chain should easily lift off the bar, with some slack between the chain’s bottom and the bar’s groove. If the chain is too loose or tight, it must be adjusted to ensure optimal performance and reduce the risk of kickback.
Adjusting Chain Tension
To adjust the chain tension, most chainsaws have a built-in tensioning mechanism. Refer to the chainsaw’s manual for specific instructions on adjusting the tension. Typically, you will need a screwdriver or a special tool to adjust the tension by tightening or loosening a tensioning screw. Ensure that the chain is properly tensioned, as an overly loose chain can come off the bar, while an overly tight chain can strain the chainsaw’s motor excessively.
Using the Correct Cutting Techniques
Always Stand Firm
Maintaining a stable and balanced posture is crucial when using a chainsaw. Stand with your feet shoulder-width apart and firmly planted on the ground. Distribute your weight evenly on both feet, which will provide stability and give you better control of the chainsaw. Avoid standing on uneven or unstable surfaces that can increase the risk of losing balance and slipping, leading to potential accidents.
Maintain a Secure Grip
A secure grip on the chainsaw is essential for maintaining control and preventing kickback. Hold the chainsaw with both hands, placing one hand on the rear handle and the other on the front handle. Ensure your hands are positioned away from the chain and the cutting area. Additionally, utilize a firm and comfortable grip, but avoid gripping the chainsaw too tightly, as it can lead to muscle fatigue and reduced control.
Avoid Overreaching
To minimize the risk of kickback, it is crucial to avoid overreaching while cutting. Overreaching can cause a loss of balance and control, making it more challenging to handle the chainsaw properly. Instead, comfortably reach the cutting area without stretching or leaning excessively. If you need to cut material out of your reach, consider using a ladder or another safe method to bring the material within your cutting range.
Positioning and Angle of Cut
Proper Positioning
Proper positioning is key to safe and effective cutting with a chainsaw. Stand to the side of the object you are cutting, with your body and feet positioned away from the potential path of the falling material. This way, if kickback occurs, you will be positioned out of harm’s way. Maintain a comfortable distance from the chainsaw, ensuring you have enough space to effectively control the tool while keeping a safe distance from potential hazards.
Working at the Correct Angle
The angle at which you cut with a chainsaw can greatly affect the risk of kickback. To minimize the chances of kickback, always cut with the bottom part of the chainsaw’s bar, known as the cutting edge, making contact with the wood. Avoid cutting with the bar’s tip, as it increases the risk of kickback. By maintaining the correct cutting angle, you can safely and efficiently complete your cutting tasks.
Avoiding Pinch Points
Understanding Pinch Points
Pinch points are areas where the chainsaw can become wedged during cutting, leading to increased friction and potentially causing kickback. These pinch points can occur when the log or branch being cut closes in on the chainsaw’s bar, trapping it in place. To prevent kickback, it is crucial to recognize potential pinch points and take proper precautions to avoid them.
Relieving Pinch Points Safely
If a pinch point occurs while cutting, it is important not to panic. Instead, stop the chainsaw immediately and avoid trying to force it out of the pinch point. Use a wooden wedge, a pry bar, or another appropriate tool to carefully relieve the pressure and safely remove the chainsaw from the pinch point. Taking the time to relieve pinch points properly can significantly reduce the risk of kickback and potential accidents.
Utilizing the Chain Brake
Knowing How the Chain Brake Works
The chain brake is a crucial safety feature on a chainsaw that helps prevent kickback. It is designed to stop the rotation of the chain in the event of a kickback, reducing the risk of injuries. Most modern chainsaws have either a manual chain brake, which is engaged by pressing a lever, or an inertia-activated chain brake, which is triggered by the sudden movement of the chainsaw. Understanding how the chain brake works and how to engage it is essential for your safety.
Engaging the Chain Brake in Dangerous Situations
In dangerous situations, such as when kickback is occurring or when you lose control of the chainsaw, it is crucial to engage the chain brake immediately. The chain brake will stop the rotation of the chain, preventing further movement and reducing the risk of injuries. Practice activating the chain brake before starting any cutting tasks to ensure that you can engage it quickly and effectively when needed.
