Preparing for the Cut
Before even touching the chainsaw, a professional spends a good amount of time looking at the tree and its area. They check which way the tree naturally leans. This is super important because it tells them which direction the tree will likely fall.
They also look for anything around the tree that could get in the way or be damaged, like houses, fences, or other trees. This initial check helps them plan the safest way to make the cut. It’s like having a map before you start a trip.
Assessing Tree Lean and Surroundings
The direction of tree lean is the most critical factor in planning a felling operation. Professionals use simple visual cues or sometimes a lean meter to confirm the lean. They observe branches, trunk curvature, and root flare to get a clear picture.
If a tree leans heavily in one direction, it’s often best to let nature help. Trying to force a tree to fall against its lean is dangerous and requires specialized techniques and equipment.
Looking at the surroundings involves identifying potential hazards. This includes power lines, buildings, roads, and even other trees that could be knocked over. Professionals also consider the escape route.
They always plan two safe paths to move away from the tree once it starts to fall. These paths should be at least 45 degrees away from the planned fall direction.
Spotting Hazards
Potential hazards are things that could be damaged or cause injury. This includes any structures within the likely fall zone. It also covers things like underground utilities, which might be damaged by the falling tree or during the cleanup.
Wind conditions are also a major consideration. A strong or gusty wind can make the tree fall unpredictably, so cutting on a calm day is usually preferred.
Planning Escape Routes
An escape route is a clear path that the operator can quickly take to get to safety. Professionals identify two escape routes. These are usually behind the tree and at an angle to the planned felling direction.
They make sure these paths are free of obstructions, like brush or logs, so they can be used easily and quickly in an emergency. Having two routes provides options if one becomes blocked or unsafe.
Choosing the Right Tools
While the focus is on electric chainsaws, professionals select a saw appropriate for the tree’s size. A larger tree needs a more powerful saw with a longer bar. They also ensure the chainsaw is in good working order.
This includes checking the chain sharpness and tension, and ensuring the battery is fully charged or that they have spare batteries. The right saw makes the job easier and safer.
Safety gear is just as important as the chainsaw itself. Professionals always wear a hard hat, safety glasses or a face shield, hearing protection, cut-resistant gloves, and steel-toed boots with cut-resistant leggings. These items protect against falling branches, flying debris, and accidental contact with the saw chain.
Chainsaw Specifications for Large Trees
For large trees, professionals typically opt for electric chainsaws with higher voltage and amperage. This translates to more power and torque. The bar length is also critical; it needs to be long enough to cut through the trunk efficiently.
A common bar length for larger trees might be 16 inches or more, depending on the saw’s power. The battery capacity is also a key factor, as larger trees require more cutting time, which drains the battery faster.
Essential Personal Protective Equipment (PPE)
Personal Protective Equipment (PPE) is the first line of defense. A hard hat protects the head from falling branches. Safety glasses or a full face shield prevent eye injuries from sawdust and debris.
Hearing protection is vital because chainsaws are very loud and can cause permanent hearing damage over time. Gloves improve grip and protect hands. Cut-resistant leggings or chaps are worn over pants to protect the legs from accidental chain contact.
Steel-toed boots protect the feet from falling objects.
The Cutting Technique
Professionals use specific cuts to control the direction and speed of the fall. The most common method involves two main cuts: the notch and the back cut. The notch is made on the side of the tree where you want it to fall, and the back cut is made on the opposite side.
The way these cuts are made is very precise and makes a big difference in how the tree falls. It’s all about guiding the tree safely.
Creating the Notch
The notch, also called the felling notch or mouth, is typically an open-faced notch. It’s made by cutting two angles on the side of the tree facing the desired fall direction. The top cut is usually angled downwards, and the bottom cut is horizontal.
The two cuts meet, removing a wedge of wood. This wedge acts like a hinge, guiding the tree as it falls. The depth and angle of the notch are crucial for a controlled fall.
A well-made notch should be about one-fifth to one-quarter of the tree’s diameter in depth. The angle of the top cut is usually around 45 degrees. The bottom cut is made perfectly horizontal.
When the back cut is made, the tree should pivot on the remaining wood between the notch and the back cut, known as the hinge wood. If the notch is too shallow or too deep, or if the angles are incorrect, the tree can fall unpredictably.
Types of Notches
The open-faced notch is popular because it offers good control. It involves two angled cuts meeting at an apex. Another type is the conventional notch, which uses a top angled cut and a bottom horizontal cut that meet.
The directional notch is a variation that creates a more precise falling direction. Professionals often choose the open-faced notch for its reliability in guiding the tree’s fall, ensuring it doesn’t sway or twist unexpectedly.
The Importance of the Hinge
The hinge is the uncut section of wood between the notch and the back cut. It acts like a door hinge, controlling the tree’s descent. The hinge should be uniform in thickness, typically about one-tenth of the tree’s diameter.
If the hinge is too thin or uneven, the tree can twist or fall sideways. If there’s no hinge (the back cut meets the notch), the tree can fall back towards the cutter. Maintaining a proper hinge is paramount for safety.
Making the Back Cut
The back cut is made on the opposite side of the tree from the notch. It should be level with or slightly above the apex of the notch. Professionals use a technique called “boring the back cut” or “plunge cut” for larger trees.
This involves plunging the tip of the saw into the wood to start the cut, which can be more precise. The back cut should not go all the way through the tree; it must stop before reaching the notch to leave the hinge wood intact.
The back cut is usually made horizontally. When the back cut is nearing completion, the tree will begin to lean and fall. At this point, the operator should stop the saw and immediately move away along a planned escape route.
Using felling wedges, which are specialized plastic or aluminum wedges, can help prevent the saw from getting pinched and assist in pushing the tree over if it’s not falling freely.
Using Felling Wedges
Felling wedges are essential safety tools when felling larger trees. They are driven into the back cut as it’s being made, or once the cut is close to the hinge. These wedges help to: 1.
Prevent the saw from binding or getting stuck in the cut. 2. Force the tree to fall in the intended direction, especially if the lean isn’t perfectly aligned with the notch.
3. Keep the hinge intact if the tree starts to tip back prematurely. Professionals carry several wedges and a sledgehammer or axe to drive them in.
Controlling the Fall
Control is achieved through the precise geometry of the notch and the hinge. The notch directs the initial movement, and the hinge governs the rate and trajectory of the fall. If the tree is exceptionally tall or has a significant lean, professionals might use ropes or specialized pulling equipment to ensure it falls in the desired direction, especially near structures or other valuable assets.
This adds an extra layer of certainty to the felling operation.
Working with Electric Chainsaws
Electric chainsaws have come a long way, and many are now powerful enough for significant tasks. Professionals use them considering their specific advantages and limitations. The main differences are noise levels and emissions, which are much lower.
However, battery life and power output can be factors for very large or dense wood. Understanding how to manage battery power and maintain the saw is key.
Power and Battery Management
For professionals, managing battery life is crucial when cutting large trees. This means having multiple fully charged batteries on hand. They might also have a charging station set up nearby.
They learn to make efficient cuts, using the saw’s power effectively without overworking it. This involves proper chain tension, a sharp chain, and not forcing the saw through the wood. Knowing when to switch batteries prevents downtime and keeps the operation moving smoothly.
A large tree might require several hours of cutting, depending on its diameter and wood type. Professionals plan their work around battery availability. This could mean cutting in stages, allowing batteries to charge while working on other aspects of the job, or having a dedicated person managing the battery rotation.
Understanding the saw’s battery indicator and its remaining run time helps in making these decisions.
Battery Types and Longevity
Modern electric chainsaws often use high-capacity lithium-ion batteries. These batteries are designed for power tools and offer a good balance of energy density and weight. Battery capacity is measured in amp-hours (Ah).
A higher Ah rating means longer run time. Professionals often invest in the highest capacity batteries available for their saw model. They also understand that extreme temperatures can affect battery performance and longevity.
Efficient Cutting Techniques
To maximize battery life, professionals use sharp chains and proper cutting techniques. A dull chain requires more power and puts a strain on the motor. They also avoid burying the bar in the wood unnecessarily.
When making cuts, they let the saw do the work rather than pushing down hard. This conserves battery power and reduces wear on the saw. Sometimes, planning the cuts to be made in sequence can optimize battery usage.
Maintenance for Performance
Regular maintenance keeps an electric chainsaw running at its best and ensures safety. This includes cleaning the saw after each use, especially around the motor and air vents, to prevent sawdust buildup. Checking and maintaining the chain is also vital.
A sharp chain cuts faster and cleaner, requiring less effort from the saw and the user.
Professionals also inspect the bar for wear and tear. They might flip the bar periodically to ensure even wear. The chain brake, a critical safety feature, is checked regularly to ensure it functions correctly.
Lubrication for the chain and bar is usually automatic, but they ensure the oil reservoir is filled and the oiler is working properly. A well-maintained saw is a reliable saw.
Chain Sharpening and Tensioning
A sharp chain is essential for efficient and safe cutting. Professionals use a file and guide or a powered sharpener to maintain the correct angle and depth of the cutting teeth. They check the chain tension regularly.
If the chain is too loose, it can derail; if it’s too tight, it can cause excessive wear on the bar and chain. The chain should be snug but still able to be pulled around the bar by hand.
Cleaning and Lubrication
After each use, the chainsaw should be cleaned. Sawdust and debris can clog air intakes, reducing motor efficiency and potentially causing overheating. The battery contacts should be kept clean.
Proper lubrication of the chain and bar is also critical. The automatic oiler system ensures the chain is lubricated as it moves, reducing friction and heat buildup. This prevents premature wear and ensures smooth cutting.
Post-Cutting Steps
Once the tree is down, the work isn’t over. Professionals consider how to safely handle the fallen tree and clean up the area. This involves limbing, bucking, and proper disposal of the wood.
A clean and safe site is the final goal.
Limbing and Bucking
Limbing is the process of removing branches from the main trunk. Professionals start from the base of the tree and work their way up. They are careful not to stand directly under limbs that are still under tension, as these can spring back unexpectedly.
Bucking is cutting the trunk into manageable lengths. This is often done by cutting from the top down, or by using a cut from the bottom up to prevent the weight of the log from pinching the saw.
Safe Limbing Techniques
When limbing, professionals identify branches that might be under tension. These are often called “springy” limbs. They make a partial cut from the top side of the limb, then complete the cut from the bottom, or vice versa, depending on the limb’s position and tension.
This controlled cutting prevents the limb from breaking suddenly and kicking back. They also ensure they have a stable footing and a clear escape path if the limb moves unexpectedly.
Efficient Bucking Strategies
Bucking requires understanding how the weight of the log will affect the cut. If a log is supported at both ends, the cut should start from the top (overbuck) about one-third of the way through, then finish from the bottom (underbuck) to prevent pinching. If the log is supported only at one end or is laying on uneven ground, the sequence might need to be reversed or adjusted.
This prevents the saw chain from getting stuck.
Disposal and Site Cleanup
After the tree is cut into pieces, professionals consider the best way to remove the debris. This might involve chipping the branches, stacking logs for firewood, or arranging for professional removal. They also ensure the work area is clean and safe, removing any remaining hazards like sawdust piles or tools.
A thorough cleanup leaves the site looking good and prevents future accidents.
Wood Disposal Options
The disposal method depends on the amount of wood and local regulations. Some people chip the branches into mulch for their garden. Larger logs can be cut into firewood.
If there’s too much wood to handle, professional services can be hired for removal or chipping. Sometimes, arrangements can be made with local sawmills or composting facilities. Planning for disposal is part of the initial assessment.
Restoring the Area
The final step is to make the area safe and presentable. This involves removing all cut wood, sawdust, and any tools. If necessary, the ground might be raked or leveled.
The goal is to leave the site as tidy and safe as it was before the work began, or even better. This attention to detail is a hallmark of professional work.
