Preparing for the Cut
Before anyone even thinks about starting a battery chainsaw to tackle a large tree, a lot of careful planning happens. This is where the real work begins, long before the saw makes its first cut. Professionals spend significant time assessing the tree and its surroundings.
They look at how the tree is leaning, what’s around it that could be damaged, and where it’s safest to fell it. This preparation is key to avoiding accidents and making sure the tree falls exactly where it’s intended.
Assessing the Tree and Surroundings
The first step for any pro is a thorough assessment. They examine the tree for any signs of decay, damage, or weakness. These issues can affect how the tree falls and might require special cutting techniques.
They also look at the ground slope and any obstacles like fences, buildings, or other trees. This helps determine the best direction to make the tree fall. It’s like being a detective, gathering all the clues to ensure a safe and controlled outcome.
This assessment also includes identifying potential hazards. Are there power lines nearby? Is the ground unstable?
Are there people or animals in the vicinity? A professional will map out escape routes, which are clear paths to move away from the falling tree. They usually plan two escape routes, at a 45-degree angle away from the direction of fall, to give them options if needed.
This attention to detail prevents many potential problems.
Choosing the Right Battery Chainsaw
Not all battery chainsaws are created equal, especially when dealing with big trees. Professionals select models that have enough power and a long enough bar to handle the job. They consider factors like battery life, chain speed, and the saw’s overall durability.
A saw that’s too small will struggle, drain batteries quickly, and could be dangerous. It’s important to match the tool to the task at hand for efficiency and safety.
Battery power is a big deal. For large trees, you need robust battery packs that can provide sustained power. Professionals might carry multiple fully charged batteries or have a system for quickly swapping them out.
They also understand the limitations of battery power compared to gas engines, especially for demanding cuts. This means they often plan their cuts to be more efficient and might avoid overly long cutting sessions without a recharge break.
Safety Gear Essentials
Safety gear is not an option; it’s a requirement. Professionals always wear a helmet with a face shield and hearing protection. They use cut-resistant trousers, gloves, and sturdy boots with good ankle support.
This protective clothing is designed to prevent serious injuries from the chainsaw chain or falling branches. It’s an investment in personal well-being that can save lives.
Here are the key pieces of safety gear:
- Helmet: Protects the head from falling branches and impacts. It usually includes a visor to protect the face and eyes, and ear defenders to reduce noise.
- Eye Protection: Safety glasses or a face shield are crucial to prevent sawdust and debris from entering the eyes.
- Hearing Protection: Chainsaws are very loud and can cause permanent hearing damage. Earplugs or earmuffs are essential.
- Cut-Resistant Clothing: Special trousers and chaps made of strong, fibrous material designed to stop a moving chain.
- Gloves: Provide grip and protect hands from cuts and abrasions.
- Steel-Toed Boots: Protect feet from falling objects and provide good traction.
The Professional Cutting Process
Once the planning is complete and safety gear is on, the cutting itself begins. Professionals use specific techniques to control the fall of a large tree. These methods involve making precise cuts in a particular order to guide the tree exactly where they want it to go.
It’s a combination of understanding tree physics and skillful chainsaw operation.
Understanding Tree Lean and Directional Cutting
The natural lean of a tree is a primary factor professionals consider. If a tree leans heavily in one direction, it will want to fall that way. Professionals use this lean to their advantage or work against it with carefully planned cuts.
They often make a “felling notch” on the side where they want the tree to fall.
This notch typically has two cuts:
- The Undercut: This is a horizontal cut made into the side of the tree, about one-quarter to one-third of the tree’s diameter deep.
- The Top Cut: This cut is made at an angle downwards, meeting the end of the horizontal undercut.
This notch creates a hinge of wood that guides the tree as it falls. The size and angle of the notch are critical for controlling the direction and speed of the fall. A well-made notch ensures the tree doesn’t kick back or twist unexpectedly.
Making the Felling Cut
After the felling notch is made, the next cut is the “back cut” or “felling cut.” This cut is made on the opposite side of the tree from the notch. Professionals leave a strip of wood between the notch and the back cut, called the “hinge.” This hinge is what controls the direction of the fall.
The back cut is usually made slightly higher than the bottom of the notch. It’s important not to cut all the way through to the notch; that would remove the hinge and lose control. The hinge acts like a door hinge, allowing the tree to swing over and fall in the desired direction.
As the back cut progresses, the tree will start to lean and eventually fall.
Here’s a simplified breakdown of the back cut:
- Placement: Made on the side opposite the felling notch.
- Height: Typically slightly above the bottom of the felling notch.
- Depth: Carried in until the tree begins to fall.
- Hinge: A crucial strip of wood left uncut between the notch and the back cut. This hinge dictates the fall direction.
Using Wedges and Tools
When felling large trees, especially those that are growing straight up or against a slight lean, professionals often use felling wedges. These are wedges made of plastic or aluminum that are hammered into the back cut as it’s being made. As the saw cuts deeper, the wedge is driven in, forcing the tree to lean in the direction of the notch.
Wedges are invaluable for several reasons:
- Control: They help prevent the saw from getting pinched in the cut, which can be dangerous.
- Direction: They can help push the tree in the intended direction of fall.
- Safety: By holding the cut open, they reduce the risk of the tree falling unexpectedly or back onto the operator.
Professionals carry several wedges and a sledgehammer specifically for this purpose. The number and size of wedges depend on the size of the tree and the type of wood. They are inserted carefully as the back cut progresses, ensuring the saw remains clear and the fall is controlled.
Battery Management During Large Cuts
One of the unique aspects of using battery chainsaws for big jobs is managing the power. Professionals understand that cutting large trees uses a lot of energy. They plan their cutting sessions and have strategies for battery power.
This includes:
- Multiple Batteries: Carrying several fully charged batteries is a common practice.
- Battery Cool-Down: Allowing batteries to cool down before recharging or using them again can extend their lifespan and performance.
- Charging Stations: Having a portable charging station or access to power can be essential for longer jobs.
- Optimized Cutting: Making efficient cuts and avoiding unnecessary saw operation helps conserve battery life.
Some professionals might even use gas chainsaws for the most demanding parts of felling very large trees, reserving battery saws for limbing or smaller tasks. However, battery technology is advancing rapidly, and many high-powered battery chainsaws can now handle substantial felling operations with proper battery management.
Post-Cut Procedures
After the tree has fallen safely, the work isn’t over. Professionals move on to processing the tree, which involves cutting it into manageable pieces. This stage also requires careful planning and execution.
Limbing the Fallen Tree
Limbing is the process of removing the branches from the trunk. Professionals approach this systematically, working from the base of the tree towards the top. They are mindful of where the branches are under tension, as cutting a branch under pressure can cause it to spring back unexpectedly.
Key considerations for limbing include:
- Working from the base: This allows them to move away from the trunk as they work.
- Cutting from the top side: For branches lying on the ground, it’s often safer to cut from the top to avoid pinching the saw.
- Cutting from the bottom side: For branches that are lifted off the ground, it might be safer to make a partial cut from the bottom first, then finish from the top.
- Avoiding tension: Identifying and carefully cutting branches that are under stress is critical.
Battery chainsaws are often well-suited for limbing due to their lighter weight and ease of use compared to some gas models. This makes them less tiring for the operator during long periods of work.
Bucking into Sections
Bucking is the process of cutting the trunk into shorter lengths, often for firewood or lumber. Professionals consider how the tree is resting on the ground. If the trunk is supported at both ends, cutting from the top first can cause the saw to bind.
In such cases, a “cut-and-a-half” technique is used, where a partial cut is made from the top, followed by a cut from the bottom to meet it.
Here’s a quick look at bucking considerations:
- Understanding Load: Where is the pressure on the log?
- Top Bucking: Cutting from the top down.
- Bottom Bucking: Cutting from the bottom up.
- Cut-and-a-Half: A combination of top and bottom cuts for logs under tension.
Safety during bucking is paramount. Professionals ensure they have stable footing and clear escape routes, even when working with a downed tree. They also manage their battery usage, switching batteries as needed to maintain continuous work.
Example Scenario: Felling a Large Oak
Imagine a large oak tree leaning slightly towards a clearing. A professional would first assess the lean and the clearing for any unseen obstacles like rocks or old stumps. They would then mark the intended fall direction.
A felling notch would be cut on the side facing the clearing, ensuring the undercut is deep enough and the top cut meets it precisely to create a strong hinge.
Next, they’d move to the opposite side and begin the back cut, leaving about 10% of the tree’s diameter for the hinge. If the tree starts to bind the saw, they would insert a felling wedge. As the back cut nears completion, the tree would begin to move.
The operator would then quickly move to a pre-planned escape route, watching the tree fall. Once it’s down, they’d start limbing and then buck the trunk into sections, using the appropriate cutting techniques based on how the logs are resting.
Battery Chainsaw Advantages and Limitations
