How to cut a tree with a chainsaw. preparation and step-by-step procedure
Sooner or later the tree dies, and then, to make room for planting new vegetation, the owner of the site is faced with the need to cut it down. To get rid of a dried tree and saw its trunk, you need to follow certain rules. This will not only simplify the work, but also make it safer for the operator and those around him.
Before starting the procedure, you must remember that felling trees with a chainsaw necessarily requires careful preparation, both the performer himself and his working tool. The chainsaw operator must protect himself/herself as much as possible from injuries and bruises.
- Clothing that fits closely to the body. There should be no shoelaces, zippers, clasps on the suit and no bracelets, chains or other objects that can get caught in a bush or branch on the operator;
- Heavy-duty, thick and watertight protective gloves. The chainsaw in them should not slip, otherwise the risk of the fall of the tool with the moving chain on the feet of the operator will increase;
- Sturdy shoes with anti-slip soles and laces hidden inside;
- safety glasses that will prevent sawdust and glass from getting into your eyes;
- Protective helmet and headphones, if the operator uses a powerful noisy chainsaw.
Do not leave the working tool unsupervised when felling trees. When sawing a pole, the handle of the garden tool must be held firmly and necessarily with both hands, while standing on a solid, stable surface.
Before you cut down trees with a chainsaw, you should prepare your gardening tool well. Sharpen the chain first. Its condition largely depends on the speed of work and the performance of the chainsaw. The second important factor is the tensioning of the saw set. The chain must not be too tight and not too loose at the same time. It’s best to let the chain slack off by about 0.5 cm when you press on it with your index finger. Check the tensioning of the saw chain every time you fill up the cutting attachment.
To fell a tree with a chainsaw, it is necessary to adhere to the following order of actions:
- First of all, personal safety of the operator must be taken care of. To shorten the time to get away from the falling trunk, you must clear the area near the tree of bushes and other vegetation in advance. Also make sure there are no bystanders or animals near the tree;
- Next, you need to start the chainsaw and, while its engine is warming up, determine the desired direction of the tree fall;
- Then it is necessary to make the first 2 cuts, which will allow the operator to cut a piece of wood, measuring 1/4 of the total diameter of the trunk. The first cut must necessarily be made directly at the bottom of the tree on the side where the trunk will fall. It must be located in the same part of the tree as the future main cut, and reach almost half the diameter of the trunk. 5-10 cm above the first one, you need to make the second cut, which will be located in relation to it at an angle of 45 ⁰. Ends the second cut at the connection to the first cut line;
- After that, pull out the separated piece of wood and begin making the main cut. At the same time, the chainsaw used must work at the maximum permissible speed;
- As soon as the main cut is made the tree starts to fall. At this time the operator needs to regroup, locate the fall of the tree and quickly move to the opposite side. The chainsaw should be turned off when the operator is moving.
After sawing the tree, the operator should inspect the stump and saw off the sharp remnants of the trunk. This helps to avoid injuries in the subsequent sawing of the tree into logs.
How to correctly cut down trees with a chainsaw: the main points
Chainsaws are cut according to trunk thickness and species of tree. For thin trunks, it makes no sense to use heavy saws. they use more fuel and oil, and you get tired of it more. The following felling pattern is used when felling:
- thick trunks over 600 mm. heavy logs over 650 mm
- medium trunks from 300 to 600 mm. average blade350-650 mm
- Thin trunks up to 300mm. a blade up to 350mm.
If you work with strong, hard wood like oak, use a medium-sized saw for even thin trunks and a heavy saw for medium- to thicker trunks.
- Before you cut the tree with a chainsaw, check the following: the thickness of the tree, how it slopes to the ground, which way it will fall, if there are any objects in the fall area, will its branches catch on other trees, etc.
- Calculate the trajectory of the trunk’s fall, based on the slope and other factors, to understand how to correctly cut a tree with a chainsaw in the right direction.
- Trim branches and limbs as much as possible so they don’t get in the way.
- Start felling according to the diagram.
Depending on how thick the tree is and what angle it is leaning, you will make a diagram of how to cut a tree with a chainsaw. An example of such a scheme for a trunk thickness of 350 mm or more is shown below:
Sketch how you will cut the trunk, you can mark the line for the trimmer with a marker. On the side where the trunk will fall, make an upper cut at a 45-60 degree angle to the line of the main cut, 20-30 mm below the virtual line.
After making the angled cut, cut a small cut parallel to the line, about 20-25% of the total diameter of the trunk, so that the trimmer line of the lower cut will connect to the upper cut. It turns out you are kind of chopping off a piece of the trunk, which is how you get the right angle to get the trunk to fall in the right direction.
The main or felling cut is made from the opposite side strictly along the virtual line. The length of the felling cut is about 65-70% of the total thickness of the trunk. there must be a distance between it and the additional cut.
As you approach the additional cut, monitor the situation. If the trunk begins to move or you hear the crunch of the tree, immediately take out the saw and insert a wedge into the main kerf. It is recommended to use a long wedge. with blows from a hammer or sledgehammer you will widen the kerf, and the trunk will roll in the direction you need.
That’s all you need to know for how to cut trees with a chainsaw without getting hurt and as quickly and efficiently as possible.
There is no way to fell trees without certain safety precautions. It is necessary to learn its basics well, and most importantly, the process of felling can not be entrusted to one person, necessarily need one or more partners.
It is categorically forbidden to smoke while using a chainsaw (or to make a fire) as there is a very high probability of ignition from gasoline fuel and dry sawdust.
- The sawyer’s body, like his face, must be securely hidden under a special protection to protect himself from sawdust and bouncing splinters.
- Make sure the tree does not hit any people, trees, or power lines when it falls.
- Do not operate in high wind gusts.
- You need to locate the fallen tree accurately and clear it of branches, trees, and other obstacles.
- When working, the chainsaw must be held with both hands.
- Do not use the edge of the saw, there is an increased risk of kickback.
- You must be ready for the chainsaw kickback during the whole cutting process.
When you saw a tree trunk or remove limbs, hold the saw below the edge of the limb.
Felling toward the slope
If the tree is straight and low (up to 4 meters), with a slope of at least two or three degrees, you can use the technique of felling toward the slope. First of all decide on the height at which you want to cut. This depends on the end goal of the procedure:
- if the stump needs to be uprooted, make the cut at a height of 70 cm to 1 m from ground level (the remainder of the trunk will later serve as a lever);
- If the stump will remain in the ground or you plan to remove it with chemicals, it is enough to leave 30-50 cm;
- If you plan to remove the tree stump with a chipper, check the height of the cutter lifting. about three quarters of this lifting height is required.
A detailed inspection of the tree will help you choose the depth of the cut. A healthy plant needs to be halved, a sick plant only needs a halved felling of about 20-40% of its thickness and a musty one about 20%.
Let’s see how to properly saw the tree in the slanting side. First check whether there are no obstacles in the place where the tree is going to fall (on the slope side). After that you need to make a bevel undercut, which will become a guide. The second, deep notch is made from the opposite side. If everything is done correctly, after these actions the tree will start to fall in the direction of its inclination.
How to use the chainsaw safely
How to cut a tree with a chainsaw without damaging surrounding objects that are nearby? Try to plan the path of the fall by first examining the area and the tree to be felled. If it is dry, large dead branches, knots can fall, so you can cut them beforehand, and you have to be careful.
You should leave the working area without hindrance. If there are other trees nearby try to work so the felled branches do not get caught in their branches, it can lead to accidents and it is not easy to get them out afterwards. You then have to process and transport or remove the felled tree from the site. Choose a direction for felling so that the tree can be easily cut and removed afterwards.
Clean up after felling is an important step. Choose a place to drop the tree where it will be convenient to cut it into pieces, and then take it off the property or load it onto a machine
How to cut a tree with a chainsaw?
In this paragraph we will list some rules and answer in detail the question how to cut the tree correctly. Due to the fact that such a tool is affordable and widely used in the preparation of firewood and work in the garden, on the plot and in the construction, park design adjustments, a chainsaw has become the most necessary item in the household. To perform the tasks you need the following equipment:
how to cut a tree down with a chainsaw
- Garden saw or saw, chainsaw or electric saw: for cutting down trees any of the listed items will do
- Personal protective equipment: body suit, goggles or face shield, leather gloves, helmet, sturdy boots-berths
- A rope with a winch
- Working with a chainsaw, first check its working order, it must have the appropriate fuel, it is a mixture of gasoline and specific oil. It is very important to observe the correct proportion of each substance. The chain also has a special reservoir where the chain oil is poured. This tool item should be taut, if you want to check it, you can put on a protective glove and crank it. Tension force must be excellent to prevent cranking, but at the same time amenable to the process. Don’t forget to check with the engine off. Also look into the tire, this hole should not be dusty.
- Prepare the area around the tree, taking into account its length, growth angle and branch spread. Apply the knowledge gained from the first list of rules for beginners. In this case, professional tree trimmers can use a rope with a winch to create tension and correct the fall direction of the trunk. Thanks to the rotating handle in the winch, this can be done with ease.
- Then start with the saw factory, once you see that it works fine, the sound is even, the chain is tensioned correctly, see how it makes the first notch. Do not continue to work if the saw begins to brake and get stuck in the trunk. The first cut is made horizontally, from the side where the tree is expected to fall. The size of the cut should be a third of the thickness of the entire trunk. The angle of the second cut to form the wedge is no more than 45 degrees.
- Above the first kerf is made a second additional, so-called horizontal felling. It should not touch the wedge made in the trunk, it is best to form at least 5 cm between them. If the tree tilts and then fouls, stop sawing, push the trunk in the right direction, and let it fall, moving a safe distance away from the stump.
What tools are needed for the work?
Once you have decided how to cut the tree, you need to prepare all the proper tools. Every worker involved in the project should have one.
- working uniforms;
- reinforced boots;
- helmet, which is equipped with a protective shield;
- Cord or twine for pulling, cutting branches;
- A plastic or wooden wedge.
A step-by-step guide
To do the job of felling a tree safely, you will need help from a few helpers (based on the height and girth of the tree).
At the very beginning, you will need to decide on the direction. Generally, the tree falls to the side where the trunk is inclined or where there are the most branches.
Using a wood hacksaw or chainsaw, trim as much of the side branches as possible. Such work will require the performer to climb the ladder, to the maximum possible height and by means of a hand saw on the tree to cut the branches.
After all branches have been cut, it will be necessary to fix a long strong rope as high as possible, by winding it around the trunk several times.
In order to make the tree itself fall in the direction we want, we must first make an undercut in the trunk by half its thickness on the other side, in which it is supposed to be put.
For large-diameter trees another cut is made from the side of the fall direction, 50mm to 100mm above the cut of the other side. After all the cuts are ready, you must pull the tree in the direction of the fall with a rope.
After the upper part of the trunk has fallen, you will need to dig up the roots in the rest of the stump, cutting them off on all sides.
On the chopped-off trunk, a loop of rope must be installed from above. Next, pull on the trunk with force, uprooting the tree stump together with the roots from the ground.
No permits are required to cut a tree. It is different if the tree itself is not privately owned and is part of a public green space. Under such circumstances, if the tree threatens to fall due to old age or illness, it is necessary to contact the respective local authorities. Such trees are cut by special organizations after application. It is allowed, of course, to invite professionals.
