How to Cut Tree Limbs with a Chainsaw (5 Pro Arborist Tips)

Cutting tree limbs with a chainsaw safely and efficiently is a skill that can transform overgrown properties into tidy landscapes and provide a sustainable source of firewood. As a seasoned arborist and wood processing enthusiast, I’ve spent years perfecting techniques that maximize safety, minimize tree stress, and optimize wood yield. In this guide, I’ll share five pro arborist tips that will empower you to tackle tree limb removal with confidence, whether you’re a beginner or have some experience under your belt.

Understanding the Task: Why Proper Limb Removal Matters

Before diving into the specifics of chainsaw operation, it’s crucial to understand why proper limb removal is so important. Poorly executed cuts can lead to several problems:

• Tree Health: Ripping bark or leaving stubs can create entry points for diseases and pests, weakening the tree and shortening its lifespan.
• Safety Hazards: Uncontrolled limb drops can damage property, injure people, or even be fatal.
• Aesthetics: Ugly, uneven cuts detract from the beauty of the tree and the overall landscape.
• Wood Waste: Inefficient cutting techniques can result in wasted firewood or valuable timber.

By following the techniques I’ll outline, you’ll minimize these risks and ensure the health, safety, and beauty of your trees.

Tip #1: Master the 3-Cut Method for Limb Removal

The 3-Cut Method is the cornerstone of safe and effective limb removal. It prevents bark tearing and ensures a clean, flush cut. I remember one particular job where a homeowner attempted to remove a large limb without using this method. The bark ripped down the trunk, leaving a wound that took years to heal and ultimately required professional intervention. Don’t make the same mistake!

Here’s how the 3-Cut Method works:

1. Undercut: Make an upward cut on the underside of the limb, about 1/3 of the way through. This cut prevents the bark from tearing when the limb falls.
2. Top Cut (Relief Cut): Make a downward cut a few inches further out on the limb than the undercut. Continue this cut until the limb breaks free. The undercut will prevent the bark from tearing back towards the tree trunk.
3. Final Cut (Collar Cut): Once the weight of the limb is gone, make the final cut just outside the branch collar. The branch collar is the swollen area where the limb joins the trunk. Cutting outside the collar allows the tree to properly seal the wound and prevent disease.

Key Considerations:

• Limb Size: For larger limbs (over 4 inches in diameter), you may need to make a deeper undercut and relief cut.
• Chain Saw Size: Use a chainsaw appropriate for the limb size. A smaller chainsaw (14-16 inch bar) is suitable for branches under 6 inches in diameter, while larger limbs may require a chainsaw with an 18-20 inch bar or larger. I generally prefer a Stihl MS 271 Farm Boss with an 18-inch bar for most limb removal tasks.
• Chain Sharpness: A sharp chain is essential for clean cuts and safety. A dull chain can cause the chainsaw to kickback.
• Stance and Balance: Maintain a stable stance with your feet shoulder-width apart and your weight evenly distributed.

Tip #2: Prioritize Personal Protective Equipment (PPE)

I cannot stress this enough: PPE is not optional. It’s the only thing standing between you and serious injury. I’ve seen firsthand the devastating consequences of neglecting safety gear. I once worked with a logger who lost an eye because he wasn’t wearing safety glasses. It’s a mistake you can’t afford to make.

Here’s a list of essential PPE:

• Helmet: Protects your head from falling debris and chainsaw kickback. Look for a helmet that meets ANSI Z89.1 standards.
• Eye Protection: Safety glasses or a face shield are crucial for protecting your eyes from flying wood chips.
• Hearing Protection: Chainsaws are loud. Use earplugs or earmuffs to prevent hearing damage. Noise levels can easily exceed 100 decibels.
• Chainsaw Chaps: These provide crucial protection for your legs in case the chainsaw kicks back. Look for chaps that meet ASTM F1897 standards.
• Gloves: Protect your hands from cuts, scrapes, and vibrations. I prefer leather gloves with reinforced palms.
• Steel-Toed Boots: Protect your feet from falling limbs and chainsaw cuts.

My Personal PPE Kit:

• Stihl ProScape Helmet System
• Pyramex I-Force Safety Goggles
• 3M WorkTunes Connect Hearing Protection
• Husqvarna Technical Apron Wrap Chainsaw Chaps
• Mechanix Wear Leather Work Gloves
• Timberland PRO Steel-Toe Work Boots

Data and Insights: According to the CDC, chainsaw-related injuries result in approximately 30,000 emergency room visits each year in the United States. A significant portion of these injuries could be prevented with proper PPE.

Tip #3: Assess the Limb and Surroundings Before Cutting

Before you even start your chainsaw, take the time to assess the limb and the surrounding area. This includes:

• Limb Weight and Direction of Fall: Estimate the weight of the limb and determine the safest direction for it to fall. Clear the area of any obstacles, such as fences, power lines, or vehicles.
• Overhead Hazards: Look for any overhead hazards, such as other limbs, power lines, or bee nests.
• Wind Conditions: Strong winds can make limb removal unpredictable and dangerous. It’s best to postpone the job if the wind is too strong.
• Escape Route: Plan an escape route in case the limb falls unexpectedly.
• Bystanders: Ensure that no one is within twice the length of the limb.

Case Study: I was once hired to remove a large oak limb that was overhanging a neighbor’s house. Before starting, I carefully assessed the limb and realized that it was heavier than I initially thought. I used ropes and pulleys to control the direction of the fall and prevent it from damaging the neighbor’s property.

Estimating Limb Weight: A general rule of thumb is that green wood weighs approximately 50-60 pounds per cubic foot. You can estimate the volume of the limb by measuring its length and diameter.

Tip #4: Use Proper Chainsaw Techniques

Proper chainsaw techniques are essential for safety and efficiency. Here are some key techniques to master:

• Stance and Grip: Maintain a firm grip on the chainsaw with both hands. Keep your wrists straight and your elbows slightly bent. Stand with your feet shoulder-width apart and your weight evenly distributed.
• Starting the Chainsaw: Place the chainsaw on the ground and engage the chain brake. Start the chainsaw according to the manufacturer’s instructions.
• Cutting with the Correct Part of the Bar: Use the bottom of the bar for felling and bucking, and the top of the bar for limbing. Avoid using the tip of the bar, as this can cause kickback.
• Avoiding Pinching: Pinching occurs when the wood closes in on the chainsaw bar, trapping it. To avoid pinching, use wedges or limbing bars to keep the cut open.
• Maintaining Chain Speed: Keep the chainsaw chain moving at a consistent speed. Don’t force the chainsaw through the wood. Let the chain do the work.
• Kickback Awareness: Be aware of the risk of kickback, which is a sudden, violent reaction that can occur when the tip of the chainsaw bar contacts an object. Always keep a firm grip on the chainsaw and avoid using the tip of the bar.

Chainsaw Maintenance:

• Chain Sharpening: Sharpen the chainsaw chain regularly to ensure clean cuts and prevent kickback. I use a Stihl 2-in-1 Easy File for quick and easy chain sharpening.
• Chain Tension: Check the chain tension before each use. The chain should be snug but not too tight.
• Bar Lubrication: Keep the chainsaw bar lubricated with bar and chain oil. This will prevent the bar from overheating and extend its lifespan.
• Air Filter Cleaning: Clean the air filter regularly to ensure proper engine performance.

Data and Insights: A sharp chainsaw chain can reduce cutting time by up to 50% and significantly reduce the risk of kickback.

Tip #5: Consider the Future Use of the Wood

When removing tree limbs, consider the future use of the wood. This will influence how you cut and process the limbs.

• Firewood: If you plan to use the wood for firewood, cut the limbs into manageable lengths (typically 16-18 inches). Split the wood while it’s still green, as it’s easier to split than seasoned wood.
• Lumber: If you plan to use the wood for lumber, cut the limbs into longer lengths and consider hiring a portable sawmill to mill the logs.
• Wood Chips: If you plan to use the wood for wood chips, rent or purchase a wood chipper. Wood chips can be used for mulch, landscaping, or composting.

Firewood Processing:

• Splitting: Use a maul, splitting axe, or hydraulic log splitter to split the firewood. I prefer a hydraulic log splitter for larger quantities of wood. My go-to is the Champion 25-Ton Horizontal/Vertical Log Splitter.
• Stacking: Stack the firewood in a well-ventilated area to allow it to dry properly. Aim for a moisture content of 20% or less before burning.
• Seasoning: Seasoning firewood typically takes 6-12 months, depending on the type of wood and the climate. Hardwoods like oak and maple take longer to season than softwoods like pine and fir.

Wood Type Selection:

• Hardwoods: Hardwoods like oak, maple, and ash are dense and burn longer than softwoods. They are ideal for heating homes.
• Softwoods: Softwoods like pine, fir, and spruce are easier to ignite and burn quickly. They are ideal for starting fires and providing quick heat.

Original Case Study: Optimizing Firewood Production:

I once helped a friend optimize his firewood production process. He was using a maul to split all of his firewood, which was taking a lot of time and effort. I recommended that he purchase a hydraulic log splitter. He was hesitant at first, but after using the log splitter for a few hours, he was amazed at how much faster and easier it was to split wood. He was able to double his firewood production in a single day.

Strategic Advantages of Using a Hydraulic Log Splitter:

• Increased Efficiency: Hydraulic log splitters can split wood much faster than manual methods.
• Reduced Effort: Hydraulic log splitters require less physical effort, reducing fatigue and the risk of injury.
• Increased Production: Hydraulic log splitters can significantly increase firewood production.

Cost Considerations:

• Chainsaw: A good quality chainsaw can cost anywhere from $300 to $1000 or more.
• PPE: A complete set of PPE can cost around $200 to $500.
• Hydraulic Log Splitter: A hydraulic log splitter can cost anywhere from $500 to $2000 or more.
• Wood Chipper: A wood chipper can cost anywhere from $500 to $5000 or more.
