How To Cut Trees With A Chainsaw
When performing the tree felling procedure, it is necessary to ensure full safety measures for both individuals and employees of organizations. Do not fell trees yourself. A partner is required. You should not make an open fire during work, and if there is one, you need to extinguish it before turning on the chainsaw. Also you cannot smoke. Care should be taken in advance to protect the face from sawdust, as they always fly off when cutting wood.
Before sawing a tree, you need to make sure that if it falls, it will not touch people, living beings, or damage the cables or wires through which the current flows. Do not work in strong winds. It is advisable to calculate in advance the direction of the fall of the trunk up to the exact contour on which all the rods and other elements are cleared so as not to damage the tree, as well as not cause its inertial overturn.
When working with full, thick posts, the chainsaw is held with both hands, while tension is constantly felt.
When sawing thick posts or massive branches, it is advisable to raise the chainsaw to a level above the shoulders.
Felling a forest: how to cut a tree so that it falls in the right direction, how to properly saw with a chainsaw in parts with your own hands
A chainsaw, with the proper power, is capable of cutting down any tree trunk for which the length of the cutting part is sufficient. It is necessary to carry out the work very carefully, adhering to all the rules. Particular attention should be paid when there is a risk of unpleasant situations due to too thick, icy or dirty wood mass. It is necessary to take into account all the factors that can complicate the work, and use the chainsaw carefully, constantly monitoring your actions and the work of your partners. In the article we’ll talk about how to properly cut a tree with a chainsaw. a diagram and instructions.
How to cut a trunk, which side. a diagram
To cut the trunk, take the following steps:
- From above, the trunk is cut in about half.
- The saw turns off (see Why the chainsaw stalls), but is left in the tree. At this time, a wedge is hammered into the hole obtained at the first stage, which must be tamped with a high-quality hatchet. This is necessary so that the saw is not distorted by the weight of the two trunks, but is between them in a free position.
- The barrel is being finished to the end point.
Sometimes the tire of the chainsaw remains in the trunk, especially for not just massive, but also hard wood. In this case, pulling it out is pointless. It is necessary to quickly turn off the motor, and then influence on both sides of the barrel from the cut from the bottom, trying to simultaneously pull out the device. This action will require the help of a partner.
Take a closer look at:
What you need to know first?
There are a range of factors that influence the correct felling. The most important conditions are divided into two categories: the technical component of the process and ensuring the safety of all persons involved.
The technical side of the issue usually requires an immediate solution even when choosing a chainsaw, since each model is designed only for a certain thickness, density and structure of the wood mass. Sawing is usually quite slow. Acceleration is possible only when working with a well-leaning tree or thin trunks (you can even use a mini chainsaw for this). Usually such plants are not of great value, therefore they are very rarely cut down.
It is necessary to take into account the thickness of the tree in advance, comparing it with the selected model of chainsaw (see Rating of the best chainsaws). The device should be optimally suited to a specific power goal. If the length of the tire of the device does not exceed 35 cm, then the maximum diameter of the tree trunk with which the work is carried out is 30 cm.When the length of the tire reaches 65 cm, then it is possible to cut down options up to 60 cm in diameter.
The sawing technology also changes with the thickness of the target. With one cut, trees up to 20 cm in diameter can be reliably cut down. If this indicator exceeds this threshold, you need to make several cuts in order to cut down the tree without damage to the device and strong efforts on the part of the workers.

The Ural chainsaw is very easy to use and therefore popular among consumers.
The higher the height of the tree, the more problematic it becomes to comply with safety regulations. Sawing also becomes more difficult, since more weight requires some effort and high power of the device. Sometimes you have to make cuts in a group, keeping a distance in level, that is, making them at different heights.
In advance, you need to measure the center of gravity to determine the fall of the tree. This indicator is influenced by the shape of the crown, as well as the characteristics of the trunk itself. These criteria have an impact not only on the position of the workers, but also on the anticipated cuts, which are optimal. Usually the trunk needs to be cut down completely and at the root, but sometimes a certain part of it is required, which also affects the cutting process.
How to cut a tree correctly. basic rules and technology
The main aspects necessary to comply with when cutting trees:
First, all the technological features are determined, only then it is necessary to clearly plan the stages of work, which will help to guarantee to protect yourself from the impact of the weight of the falling tree. Even with extensive work experience, it is necessary to constantly take care of your own safety, since the highest number of injuries are received by employees who have long been accustomed to a constantly tense and dangerous environment in this field.
Sawing branches and a trunk with a chainsaw
The branches must be detached from the bottom of the tree, which is already on a flat surface. You should alternately finish the rows of branches, getting to the central ones, in order to gradually completely clear the trunk. All elements must be removed separately, it is advisable to transfer the sawn-off parts into a certain container during the work process.
How to properly and quickly cut a tree with a chainsaw
Dry trees appeared at the dacha, and the farm has a chainsaw. The question immediately arises: how to properly cut a tree with a chainsaw.
Cutting a tree is easiest to do with a chainsaw, as it does not require much physical effort.
A chainsaw is a great tool and can handle any trunk with ease. Only the tree has grown big and tall. In order to solve the problem of how to properly cut it down with a chainsaw and not suffer at the same time, you should consider some of the nuances of this rather dangerous event.
Features of felling
In order to understand how to properly cut wood with a chainsaw, you should consider the factors that affect the felling process. Two aspects of the problem should be noted here: the technical side and the security issue.
Tree felling scheme.
The technical side of the issue depends on a number of parameters. First of all, different types of trees have different wood structures and different densities. The denser the wood, the slower the sawing process.
The underlying factor is the diameter (thickness) of the tree. Depending on this parameter, it is necessary to select the power of the chainsaw. Light saws (bar length up to 35 cm) are used to cut trees with a diameter of no more than 30 cm. Medium saws (bar length 35-65 cm) can be used when it is necessary to cut a specimen with a diameter of up to 60 cm. Finally, if it is necessary to cut trees with a chainsaw larger size, use a heavy saw (bar length over 65 cm). In addition, the sawing technology itself depends on the thickness of the trunk. Specimens up to 20 cm in diameter can be cut with one cut, while larger trees require two or more different cuts.
The height of the tree, in addition to safety issues, affects the cutting technology, as it determines the weight. It may be necessary to make several cuts at different heights from the ground. The type of crown and the shape of the trunk largely determine the direction of the fall due to the change in the center of gravity. All this influences the choice of the location and direction of the cuts. Finally, the cutting technology depends on whether you need to cut the trunk at the root or saw off part of it, that is, at what height the sawing is performed.
Hands must be protected with gloves when using the chainsaw.
It is possible to cut a tree with a chainsaw correctly and safely only after carrying out certain preparatory work. First of all, it is necessary to clear a place for work, as well as a path for a possible retreat from the falling tree. So, the free space on the working side should be: with a trunk diameter of up to 20 cm. at least 80 cm; with a diameter of up to 30 cm. not less than 1.2 m; with a diameter of up to 50 cm. at least 2 m.The working area is determined after calculating the direction of fall.
The preparation of the tree itself consists in cutting branches and twigs from the trunk, which are located below the head of the worker. Clears the direction of the fall.
Before starting work, you should determine the readiness of the chainsaw. The condition of the cutting elements and the chain tension are assessed. Gasoline filling and oil level are checked.
Felling thick trunks
Saw direction when felling wood.
The question of how to properly cut a tree of large diameter is solved by several characteristic cuts. First, at a convenient height for work, the line of the tree cut is outlined. This virtual mower line is then cut from above at a 45º angle. This cut is made from the side of the inclination of the trunk, that is, from the side of the tree falling after sawing. At the level of the intended mowing line, a horizontal cut is made (on the same side as the bevel cut) before connecting to the bend cut inside the trunk. The cutting depth should be a quarter of the trunk diameter at the cutting point. The distance between the horizontal cut and the beginning of the inclined cut along the surface of the trunk in the longitudinal direction is 20-40 cm. When cutting, one should strive to observe the recommended angles and cutting direction. After removing the cut piece of the trunk, the cut will look like a log house with an ax.
The next horizontal cut is made from the opposite side of the tree at a height 2-3 cm higher than the height before the first horizontal cut. The cut is made so that its depth is about 10% less than the cut already made on the other side. At the end of the cut, there may be a crackling sound or slight movement of the wood. In this case, it is necessary to quickly remove the chainsaw from the cut. A wedge or a special felling blade is inserted into this cut. By pressing with your hands or using a wedge, the barrel roll is provided.
Before making the second horizontal cut, make another bevel cut, then join them together. This technology eliminates the risk of the chainsaw cutting element being stuck.
Then branches and twigs are cut down. The trunk is cut into pieces. It is recommended to cut the trunk by lifting it off the ground in a horizontal position. You can use goats for this.
Additional guidelines can be followed to ensure proper felling. You should not put significant effort on the chainsaw: with a normal sharpening of the chain, the cutting speed is practically independent of the effort. The upper large branches must not be cut from below: at the bottom, only a cut is made in no more than half the diameter of the branch, in order to avoid jamming the saw. When sawing, it is not recommended that the direction of travel of the saw chain is on the body of the worker. It should always be slightly off to the side.
Felling small trees
Trees up to 20 cm in diameter are classified as small and can be felled with one cut. The technology for cutting such specimens is as follows. From the side of the inclination of the trunk, a transverse cut is made with a chainsaw. The length of the notch is about half the thickness of the trunk. Then the trunk is trimmed on the other side at the same level, until the tree moves. A little effort is applied and the tree falls in the right direction. These cuts are made first at the shoulder level of the person. Then, with one cut, the remainder of the trunk is cut off at the root (soil) level.
After cutting the trunk, you should immediately cut the branches on it. Their cutting begins from the distant branches. Small branches and twigs are removed with a single movement of the saw. Thicker branches are first sawn from the top side and finally cut from the bottom. This should be done to prevent the saw chain from wedging.
The fall of a tree when notched must be carefully calculated so that the work does not lead to injuries.
The question of how to properly cut trees with a chainsaw cannot be solved without ensuring the safety of workers. First of all, it is strictly forbidden to cut down with a chainsaw alone. There should always be a partner. Due to the flammability of sawdust and gasoline in the tool, open flames and smoking are prohibited. The face and body must be protected from chips and sawdust.
Care must be taken to prevent the sawn tree from falling on the worker, other people or electric mowing line. Do not work in strong winds. The direction of fall of the trunk must be carefully calculated and cleaned of obstacles (branches of other trees, etc.).
In order to cut, the chainsaw must be held with both hands. Do not work with the edge of the saw due to the risk of kickback. The risk of tool kickback must be taken into account during the entire sawing process. When sawing a tree or cutting branches, the chainsaw should be no higher than shoulder level.
How to properly cut branches from a fallen tree
In the process of cutting branches from a fallen tree, there is a risk of pinching the tire, therefore, when sawing, you need to adhere to several rules.
- Branches should be sawn from the side opposite to the slope.
- Branches should not be cut with the tip of the tire, since this method of cutting there is a risk of rebound and injury.
- Clamped branches must be filed from the load side.
Often, in the process of cutting off trapped branches, they can bounce, so when sawing, you need to choose a safe distance.
Safety precautions and personal protective equipment
A chain saw is source of increased danger, working with it requires compliance with certain rules.
- The operator must be in good condition when working with the tool. It is forbidden to use the chainsaw in AL-KOH or drug intoxication.
- It is forbidden to touch the saw headset with your hands while the engine is running on the chainsaw.
- To avoid getting sawdust in the eyes, the operator must wear protective goggles or use a face shield when sawing.
- The chainsaw is loud, so care must be taken to protect your hearing. Use headphones or earplugs.
- In the process of felling a tree, there is a risk of dry branches falling on the operator, so work must be done in a helmet or hard hat.
- Shoes must be durable and non-slip, it is best to use special shoes with protective plates installed in the socks to prevent injury if the chain breaks and falls into the leg.
- Clothing should fit snugly around the body to reduce the risk of it getting caught and wrapped around the chain. The material from which the clothes are made must be dense and durable.
- Working with a chainsaw alone is not recommended.
- Do not refuel the fuel indoors, as well as directly at the work site; after refueling, check the tightness of the tank neck plug.
- Do not refuel the saw while the engine is running.
- The assembled saw may only be transported with the protective tire cover on.
This is not the whole list of rules that must be remembered and followed in order not to get injured. detailed instructions can be found in the manual that comes with all chainsaws.
How to cut a tree into chunks correctly
Sawing the trunk of a fallen tree is much easier than cutting down a tree at the root, but there is a certain risk here. For example, improper cutting of trees can lead to the fact that it squeezes into a tire in the trunk and then you have to use a jack or lift the trunk with crowbars, which will take a lot of time and effort. In order to avoid such situations, it is necessary to assess the position of the trunk in advance and first saw it in those places where there is tension.
It is better to cut the trunk from the top of the head, gradually moving towards the butt.
The cut can be either top or bottom. The upper cut is performed until the trunk begins to lower and compress the tire, after which, if possible, it is necessary to finish the trunk from the bottom. If there is no opportunity, then a few more are made next to the first cut, until the tire stops pressing.
After the trunk is cut into several large pieces that can be rolled, they are sawn into chocks with an upper cut.
The consequences of improperly operating a chainsaw can be very sad, so you should never neglect the rules of working with a saw. It is important to observe safety precautions and use personal protective equipment. We advise, before sawing with a chainsaw, read the operating rules that are in the user manual.
Chainsaw Felling: A Beginner’s Guide
The process of felling large trees with a chainsaw requires a professional grade tool, special equipment and knowledge of the relevant section of safety rules. This information is about how to properly cut a tree with a chainsaw without the risk of damaging buildings and landscape elements located at a short distance.
Self-cutting trees with a chainsaw allows you to save money on wages for a specialist, as well as choose a convenient time for this work. A positive result is facilitated by the presence of a semi-professional or better professional grade chainsaw.
How to use a chainsaw correctly
A chainsaw is a technically difficult and dangerous tool, for this reason, when working with a saw, certain rules must be followed. Inexperienced users often treat the work with a chainsaw with less attention and break the rules, this leads to injury to the operator or breakdown of the tool.
In this article, we will consider how to properly prepare a chainsaw for work, what are the rules and methods for felling and sawing trees, we will tell you about how to saw correctly with a chainsaw, we will dwell on safety.
Chainsaw safety precautions
Yes, there are special rules:
- Use appropriate footwear and clothing: non-slip footwear, goggles, gloves, heavy clothing. Earplugs help reduce noise.
- Check if the chain is well sharpened and tensioned. The tension is good if the guide teeth stay in the groove as you pull the chain off the top of the bar. When filling with oil, it is advisable to always check that the chain is well tensioned.
- Do not work in windy conditions.
How to cut a tree with a chainsaw without harming the surrounding objects that are located nearby? Try to plan the trajectory of the fall, having previously studied the territory and the tree itself that you are going to cut down. If it is dry, large dead branches, twigs may fall off, so they can be cut beforehand, and you need to be careful here.
You must leave the work area unhindered. If there are other trees nearby, try to work so that the sawn branches do not get stuck in their branches, this can lead to an accident, and it is not easy to get them later. The cut tree you will need to then process and take out or remove from the site. Choose a direction for felling so that you can easily cut and remove the tree later.
Harvesting is an important step after felling a tree. Choose a place for the fall of the tree where it will be convenient to saw it into pieces, and then remove it from the site or load it onto a machine
How to properly cut a tree with a chainsaw: safety rules when felling trees
Felling trees with an ax and a regular saw is a thing of the past; most owners of private houses and summer residents today acquire chainsaws. It is necessary to have a chainsaw. if there are no old trees on the site for felling, you periodically need to cut branches, and in case of force majeure, it often happens that a large tree falls or splits. here you really need to know how to properly cut a tree with a chainsaw.
A similar situation can develop both in the forest, where you will go on vacation, and in the country. If you notice that the tree is in emergency condition and its fall threatens property damage, you should not pull with the AL-KO
Many do not think about safety, but several important rules, in order to avoid dangerous situations, need to be learned.
The order of work when carrying out tree felling
Undercutting takes place in several stages. The first (upper) undercut is made at a quarter of the trunk diameter, at an angle of 45 °, you need to approach the tree from the side of the fall. Then an undercut is made from below. It is done horizontally to the level where both undercuts are connected. After making two notches, you should have a 45 ° angle cut into the trunk. Do not cut the tree completely, otherwise it will be impossible to guess in which direction its trunk will fall.
The felling cut is now in use. Before starting work, make sure that there are no people, pets or objects in the fall area that can be damaged. The felling cut is made on the opposite side of the intended direction of fall of the trunk, it should be located at a distance of five centimeters from the bottom notch, parallel to it.
Slowly lower the saw into the trunk. To prevent the tire from getting stuck in the trunk, insert a wedge into the felling cut before the tree starts to fall. The wedge must be plastic or wood, the metal wedge can damage the chain. Engine speed during saw operation. maximum.
While working, watch carefully where the barrel is going. So you can take timely action if you feel that the fall has gone in the wrong direction.
Arrows indicate cuts: 1. upper, 2. lower, 3. felling. The unfinished part of the tree is a hinge to prevent falling in an unwanted direction
Two options for the notch: in the first case, the notch was made with a double right angle, it is more difficult to make it, but the tree is guaranteed to fall in the direction you planned, in the second case, the most common option of the notch, described above, is performed
When the trunk starts to fall, quickly remove the saw from the cut, turn off the engine and leave the work area. Perform all actions quickly, delay can be dangerous.
Below is an example of work. fast felling of a tree, where the necessary undercuts take a minimum of time:
That’s all, we looked at how to properly cut trees with a chainsaw. if you follow the above rules, you can easily knock down the tree you want. And the main thing here is to be attentive and focused. Before the first VAL-KO, you can practice on a small dry tree, if you have one on your site, or look for one in a nearby planting.
How to properly cut a tree with a chainsaw. safe and effective!
Not a single summer resident can do without a chainsaw! This tool saves a lot of time, but it can also cause serious injury. Do not neglect safety rules!
How to operate a chainsaw correctly. what the instructions are silent about?
We will not give you advice to look into the instructions before starting work. well, who is looking there, you might think! Frankly speaking, the instructions attached to the tool do not always clearly and intelligibly explain how to use it, how to regulate it. This is especially true for manufacturers of inexpensive saws. it is impossible to simply pull the chain using instructions, because the manufacturer skimped on high-quality printing, and the image of the parts is completely blurry.
We will try to convey the basic safety rules to you as clearly as possible! First rule. protect your hands, face and body!
- Clothes should fit snugly to the body, not hang down or dangle. No scarves, laces, bracelets or chains! Under the chain, they can pull you too!
- Wear sturdy, thick gloves that will comfortably hold the saw. Gloves will protect your hands not so much from the saw itself as from the whipping branches.
- Wear non-slip sneakers.
- Protect your eyes! Glasses made of glass that do not break off are best.
- A helmet, special headphones or earplugs will not be superfluous.
Do not leave the saw running unattended, always hold the tool with both hands. Start by settling on small branches that are conveniently located. At first, your hands get tired quickly, so do not plan large volumes on the first day after buying an instrument. And the tool itself must first be run in on small branches.
Sharpening and tensioning the chain. taking care of the tool
A well-sharpened chain is a factor on which your safety, and the effectiveness of the tool, and its serviceability depend. Never start work if the chain is dull. this is evidenced by small sawdust and the need to apply force when cutting. The sharp chain itself bites into the tree, you can even prune trees like this. the cut will turn out to be even and uniform.
Always check the chain tension before starting work. A well and correctly tensioned chain can be easily turned by hand, does not sag from below. However, there is no need to drag it, otherwise it will simply overheat. The guide teeth should protrude slightly from the bar as the chain is tensioned, but not completely out of the chain. The chain tension should be checked every time you stop to refuel or change position. Better to play it safe once again. and you will be safe, and the instrument is working properly.
How to properly cut a tree with a chainsaw?
Remember that when felling or pruning trees, you must take a stable position, nothing should prevent you from taking a step back or forward or sideways. You must plan for an escape route in case of unforeseen circumstances and draw up a thoughtful felling plan. Make sure there are no branches in the tree that might fall on you. It is better to remove especially inconvenient branches with a hacksaw.
The safest way is to cut from top to bottom, starting with the highest branches. However, you cannot cut branches that are above the shoulder. First, the tree must be filed. for this, a piece of wood must be cut at a 45 ° angle from the side where the tree will fall, на of the trunk diameter. First, a bottom cut is made, which should be on the same line as the future felling cut. The bottom cut is made to almost half of the trunk. Then, at an angle of 45 °, make the next cut 5-10 cm higher than the bottom one, and cut until the mowing lines converge. Remove the piece of wood and start the felling cut.
Cut at maximum speed, slowly plunging the tool into the wood. As soon as the tree starts to fall, immediately remove the bar from the cut and turn off the saw. Leave the fall area. When sawing a fallen tree, be careful with small branches. they are the ones that most often lead to a reverse impact, which is associated with almost all injuries.
