We’re here to guide you through the process of how to fell a tree with a chainsaw, breaking down each step so you can approach the job with confidence and, most importantly, safety. From assessing the tree to making the final cut, we’ll cover everything you need to know.

How to Fell a Tree with a Chainsaw: A Step-by-Step Masterclass

Felling a tree with a chainsaw is a skill that requires respect for the power of the tool and the forces of nature. It’s not just about cutting; it’s about planning, preparation, and execution. When done correctly, it’s a rewarding and efficient process. When done incorrectly, it can be incredibly dangerous. This guide will walk you through the essential steps to safely and effectively fell a tree with your chainsaw.

1. Safety First: The Non-Negotiable Foundation

Before you even think about starting the chainsaw, your safety and the safety of those around you must be the absolute top priority. This isn’t a suggestion; it’s a fundamental requirement. We’ll cover the essential safety gear and precautions you need to take.

Personal Protective Equipment (ppe): Your First Line of Defense

Wearing the right PPE is crucial. Think of it as your personal safety suit. Without it, you’re leaving yourself vulnerable to serious injury.

• Chainsaw Safety Helmet: This should include a face shield (a mesh screen or visor) to protect your eyes and face from flying debris and a hearing protector to prevent long-term hearing damage from the chainsaw’s noise.
• Safety Glasses: Even with a face shield, a good pair of safety glasses provides an extra layer of protection for your eyes.
• Chainsaw Gloves: Look for gloves made of leather or synthetic materials that offer good grip and some protection against cuts.
• Chainsaw Chaps or Pants: These are made with special protective material designed to stop or slow down a moving chain if it comes into contact with your legs. This is arguably the most important piece of protective gear for your lower body.
• Steel-Toed Boots: Sturdy, slip-resistant boots with reinforced toes will protect your feet from falling branches or the chainsaw itself.

Work Area Safety: Clearing the Path for Success

A cluttered work area is an invitation to disaster. You need a clear, unobstructed path for yourself and a safe zone for the tree to fall into.

1. Assess the Surroundings: Look for power lines, buildings, fences, vehicles, or any other structures that the tree could fall on. If there are any overhead hazards, do NOT proceed. Call a professional.
2. Establish an Escape Route: Plan at least two escape routes. These should be at a 45-degree angle away from the intended direction of fall. Clear these routes of any tripping hazards like branches, rocks, or tools.
3. Clear the Base of the Tree: Remove any brush, debris, or undergrowth around the base of the tree. This will give you a stable footing and prevent the saw from snagging.
4. Designate a Safety Zone: Ensure no one else is within a radius of at least two tree lengths from the tree being felled. Keep pets and children far away.

2. Assessing the Tree: Understanding Your Target

Every tree is unique, and understanding its characteristics is key to a successful and safe felling operation. This involves more than just looking at its size.

Tree Health and Lean

The health and natural lean of the tree will significantly influence your felling direction. A healthy tree with no significant lean is generally easier and safer to fell.

• Lean: Observe which way the tree naturally leans. This is the most important factor in determining your felling direction. You want to fell the tree in the direction of its lean, or at least not directly against it.
• Rot or Decay: Look for signs of rot, disease, or damage. Hollow spots, fungal growth, or dead branches can weaken the tree and make it unpredictable. If you suspect significant rot, consider consulting a professional arborist.
• Dead or Broken Branches: These can fall unexpectedly during the felling process, posing a serious hazard. It’s often best to remove large, dead branches before you begin felling.
• Root System: Examine the base of the tree for any signs of root rot or damage. A compromised root system can lead to unpredictable falling.

Wind Conditions

Never fell a tree in strong or gusty winds. Wind can drastically alter the intended felling direction, making the operation extremely dangerous. Wait for calm conditions.

3. Planning the Felling Direction: The Art of Control

This is where strategy comes into play. You need to decide precisely where the tree will fall and how you’ll guide it there. (See Also: how to remove tree sap from car)

Determining the Felling Zone

Your felling zone is the area where you want the tree to land. It needs to be clear and free of obstacles.

1. Measure the Tree Height: Roughly estimate the height of the tree. This will give you an idea of the potential fall radius.
2. Identify Obstacles: Ensure the entire fall zone is clear of anything the tree could hit on its way down or upon impact, which could cause it to bounce or split unexpectedly.
3. Consider the Lean: As mentioned, the natural lean is your primary guide. You’ll typically want to fell the tree in the direction of its lean.

Using Wedges and Ropes (optional but Recommended for Larger Trees)

For larger trees, or when felling against the natural lean, wedges and ropes can be invaluable tools for controlling the fall.

• Felling Wedges: These are plastic or aluminum wedges driven into the back cut to help guide the tree and prevent the saw from binding. You’ll typically need two or three.
• Throwing Rope: A strong rope can be thrown over a higher branch in the desired felling direction. This can then be used to pull the tree over, especially if there’s a slight lean against your desired direction.

4. Preparing the Chainsaw: Your Cutting Companion

A well-maintained and properly set up chainsaw is essential for efficient and safe cutting. Don’t skip these checks.

Chainsaw Maintenance Checks

Before every felling operation, perform these checks:

1. Chain Sharpness and Tension: A sharp chain cuts cleanly and efficiently, reducing strain on you and the saw. A loose chain can be dangerous. Ensure it’s properly tensioned according to your chainsaw’s manual.
2. Bar Condition: Check the guide bar for wear or damage. Ensure the oil hole is clear for proper lubrication.
3. Fuel and Bar Oil Levels: Make sure you have enough fuel and bar oil. Always use the correct fuel-to-oil mixture for your saw.
4. Brakes and Safety Features: Test the chain brake to ensure it engages and disengages properly. Check that the throttle lock and chain catcher are in good working order.

Starting the Chainsaw Safely

Starting a chainsaw requires specific steps to ensure safety. Always start the saw on the ground or a stable surface.

• Place the saw on firm ground.
• Engage the chain brake.
• Place your foot through the rear handle loop.
• Grip the front handle firmly with your other hand.
• Pull the starter cord with a smooth, strong motion.

5. Making the Cuts: Precision and Technique

This is the core of the felling process. The cuts you make are critical for controlling the direction and ensuring a clean fall.

The Notch Cut (face Cut)

The notch cut determines the direction of fall. It’s typically made on the side of the tree facing your intended felling direction.

1. The Undercut (Bottom Cut): This cut is made horizontally into the tree, about one-quarter to one-third of the way into the trunk. It should be as level as possible.
2. The Top Cut: This cut is made at an angle, meeting the end of the undercut. The angle is usually around 45-60 degrees. The goal is to remove a wedge of wood. The depth of the notch should be about 1/5 to 1/4 of the tree’s diameter.
3. Clear the Notch: Ensure the notch is completely clear of sawdust and wood chips.

The Felling Cut (back Cut)

This cut is made on the opposite side of the tree from the notch and is what actually severs the tree. It must be made precisely to control the fall.

1. Positioning: The back cut should be made slightly above the level of the undercut (about 1-2 inches higher). This creates a hinge.
2. The Hinge: This is the most critical part. The hinge is a strip of uncut wood left between the notch and the back cut. It acts like a door hinge, controlling the direction and speed of the fall. The hinge should be about 1/10 of the tree’s diameter in thickness and run the full width of the cut.
3. Making the Cut: Start the back cut. If you are using felling wedges, insert them into the back cut as soon as there is enough space to do so. Continue cutting until the tree begins to fall.
4. Listen and Watch: As you cut, listen for creaking sounds and watch the top of the tree for movement.

What If the Tree Doesn’t Fall?

If the tree doesn’t fall immediately after the back cut is complete, you may need to use your wedges or, if you have one, a pull rope. Never stand directly behind the saw or the falling tree. Use your escape route. (See Also: how to draw a tree easy)

6. The Fall and Post-Felling Procedures

Once the tree is falling, your job isn’t quite done. You need to ensure your own safety and then deal with the felled tree.

Retreating Safely

As soon as the tree begins to fall, immediately disengage the saw, re-engage the chain brake, and retreat along your planned escape route. Do not turn your back on the falling tree. Be aware of potential hazards like falling branches or the tree bouncing or kicking back.

Assessing the Fall

Once the tree has landed, wait a moment to ensure no further movement or settling occurs. Check for any lodged branches or unexpected shifts.

Limbing and Bucking

Once it’s safe, you can begin the process of limbing (removing branches) and bucking (cutting the trunk into manageable sections). Remember to always maintain a stable stance and be aware of the tension in the wood, which can cause the saw to bind.

7. Advanced Considerations and When to Call a Professional

While this guide covers the fundamentals, some situations demand professional expertise. It’s crucial to recognize your limits.

When to Call a Professional Arborist

There are several scenarios where attempting to fell a tree yourself with a chainsaw is ill-advised:

• Proximity to Structures: If the tree is close to your house, garage, power lines, or any other valuable property, the risk of damage is too high for amateurs.
• Large or Dead Trees: Very large trees, or trees that are significantly dead or decayed, can be unpredictable and dangerous.
• Complex Lean or Multiple Leans: If a tree has a severe lean, leans in multiple directions, or is leaning against another object, it requires advanced techniques.
• Difficult Terrain: Steep slopes or uneven ground can make it harder to maintain a stable footing and control the fall.
• Lack of Experience: If you’re new to chainsaw operation or tree felling, it’s best to gain experience under the guidance of a professional or practice on smaller, less risky trees.

Understanding Tree Dynamics

Trees are complex living organisms. Their internal structure, how they respond to cutting, and the influence of external factors like wind and gravity all play a role. As you gain experience, you’ll develop a better intuition for these dynamics.

The Importance of Practice

Like any skill, felling trees with a chainsaw improves with practice. Start with smaller, less challenging trees in a controlled environment. The more you do it, the more comfortable and proficient you’ll become.

8. Chainsaw Safety Features Explained

Modern chainsaws are equipped with several safety features designed to protect the operator. Understanding what they are and how they work is vital. (See Also: how many magic tree house books are there)

• Chain Brake: This is the most important safety feature. It’s typically a lever located in front of the top handle that, when activated (either manually or by inertia), stops the chain from moving. Ensure it’s working correctly before each use.
• Chain Catcher: Located beneath the guide bar, this small projection is designed to catch the chain if it breaks or derails, preventing it from flying back towards the operator.
• Anti-Vibration System: Chainsaws produce significant vibration. Anti-vibration systems isolate the handles from the engine, reducing operator fatigue and the risk of Hand-Arm Vibration Syndrome (HAVS).
• Throttle Lockout: This prevents accidental acceleration of the engine. The throttle trigger cannot be pulled unless the lockout is depressed.
• Front Hand Guard: This protects the operator’s hand from the chain and guide bar.

9. Dealing with Binding and Kickback

These are two of the most dangerous situations you can encounter when using a chainsaw. Knowing how to prevent and react to them is critical.

Understanding Binding

Binding occurs when the chainsaw’s guide bar gets pinched in the wood. This can happen if the tree shifts, or if the back cut is not made correctly.

• Prevention: Use felling wedges. Ensure the back cut is made slightly higher than the undercut. Don’t cut too deep into the hinge.
• What to Do: If the saw binds, do not force it. Turn off the engine. Carefully try to remove the saw. If it’s severely stuck, you may need to use wedges or a pry bar to open the cut.

Understanding Kickback

Kickback is a violent, upward and backward motion of the guide bar and chain that can occur when the tip of the guide bar (the kickback zone) strikes an object or when the wood closes in and pinches the chain in the cut. It’s extremely dangerous and can lead to severe injury.

• Prevention: Avoid cutting with the tip of the bar. Be aware of the kickback zone. Keep the chain sharp. Ensure the chain brake is functioning. Maintain a firm grip with both hands.
• What to Do: If kickback occurs, the chain brake should engage automatically. Maintain your grip and let the saw stop. Never try to grab a runaway saw.

10. Post-Felling Cleanup and Maintenance

Once the tree is safely on the ground, your work isn’t entirely finished. Proper cleanup and saw maintenance are essential for safety and longevity.

Securing the Area

Even after the tree has fallen, it’s wise to keep the area secured for a short period, especially if there are any loose branches or if the ground is unstable.

Cleaning the Chainsaw

After each use, clean your chainsaw thoroughly. Remove sawdust and debris from the engine, air filter, and guide bar. This ensures optimal performance and prevents premature wear.

Sharpening the Chain

A dull chain is inefficient and dangerous. Sharpen your chain regularly, ideally after every few hours of use, or when you notice a decrease in cutting performance.

Storing the Chainsaw

Store your chainsaw in a dry, secure location, out of reach of children. If storing for an extended period, follow the manufacturer’s recommendations for fuel stabilization and storage.

Conclusion

Felling a tree with a chainsaw is a task that demands respect, preparation, and a commitment to safety. By understanding the tree, planning your cuts meticulously, using the right safety gear, and employing proper techniques, you can significantly increase your chances of a successful and safe operation. Always prioritize safety over speed, and don’t hesitate to call a professional when faced with challenging or dangerous situations.
