A chainsaw, while observing the power indicators, can cut down absolutely any tree trunk for which it only has enough cutting power. It is necessary to conduct the split very carefully, follow all the basic rules, and pay special attention if there is a risk of developing unpleasant situations due to an excessively thick, icy, or contaminated trunk.

It is necessary to take into account those factors that can complicate the process of working with a chainsaw at times and use the device carefully, all the time to monitor their actions and the work of their partners.

What you need to know when felling

There are certain factors that have a significant impact on the correct felling of the forest. In this case, more important conditions are divided into two groups: technical component of the process and ensuring the safety of all persons involved in this work.

The technical side of this issue requires immediate resolution during the choice of a chainsaw, since any model will be designed for a certain density, thickness and structure of trees. Sawing is most often slow. You can work accelerated only on condition that you have a wood that can be cut well or a tree with a thin trunk (you can even use a small chainsaw for this). Such plants do not represent any value, therefore, they are cut quite rarely.

It is necessary to take into account the index of barrel thickness in advancecomparing it with the selected model of the chainsaw (for this it is best to use the rating of chainsaws). Such a device must meet its power standards and the specific purpose of use. If the total device bus length does not exceed 35 cm, then the maximum diameter of the tree trunk with which work occurs is thirty centimeters. If the tire length equals 65 cm, then you can make trunks trunks up to 60 cm in total diameter.

For more massive woody plants, complex and powerful saws are used that exceed the standard weight. The length of the tire in such devices goes far beyond the mark of 65 cm.

The lower the height of the tree, the more difficult it becomes to comply with all safety regulations. Also, the process complicates the sawing, as more weight requires a certain effort of a specialist and high power of the device. In some cases, it is necessary to make cuts in a comprehensive manner, while observing the overall distance in level, that is, making them at different heights.

Also need even before work, measure the center of gravityto understand the path of the fall of the tree. This will be affected by the shape of the crown of the tree, as well as the trunk itself. Such criteria influence not only the position of the workers, but also the places where the cuts will take place. Most often, the trunk is cut off completely, under the root, but sometimes it is necessary to chop only a certain part of it, which also affects the process of felling of stands.

Instructions for cutting small trunks

The technology of split of plantings of large and small diameter will be slightly different. First you need learn to cut small trunks:

  1. Search for the slope of the tree. In this case, even slight gravity is suitable, but the more such a feature manifests itself, the more you can notice the exact side of the fall. It is best to cut straight trees in a convenient place for stalling. One notch will be about half of the total diameter of the trunk.
  2. On the other hand, the same notch is created at the same level. It is necessary to wait for the time when the tree begins to bend in a certain direction, that is, the fall will differ. To begin with, a tree is dumped when a cut is made for safety, the rest of the array is left and only a small stump is left.
  3. Sawing a tree into additional parts begins with the branches that are located farthest. Small branches can be cut quickly in one step, and thicker branches are best in two so as not to damage the working tool. In this case, the saw chain should not touch the ground, as otherwise it will quickly become dull.

The principle of cutting large trees

Large include trees that in total diameter exceed half a meter. At first, the trunk is used as a support, but sawing the structure can only be done after choosing the angle of incidence. The principle of action is as follows:

  1. From top to bottom you need to make a slice of 60 degrees. It should go exactly from the side of the slope you need. At the same time, constantly monitor the exact angle of incidence and keep the saw level.
  2. From below, a line is drawn in the horizontal direction, which should be adjacent to the extreme inner point once. After the stop, you can take out a corner consisting of wood, which will help to make a side cut.
  3. On the other hand, located opposite from the first two cuts, you need to make a horizontal sawing, which should begin slightly higher than the lower level of cuts on the opposite side. At the same time, it is necessary to cut deeply, but it is forbidden to perform such an operation completely, that is, the tree should continue to be upright.
  4. At the second file you need to pre-mount the prepared wedge or a special shoulder blade for the ditch. The remaining volume can be removed with a spatula when finishing from the inside.

There is another additional way of felling stands. To begin with, the tree is cut completely and through. Then it moves in the opposite direction with a general bias to the left side and reaches the middle. A wedge is located under the second notch. Then the tree is finished to the end, but from the opposite side.

Rules for sawing trunk and branches

Branches need to start disconnecting from the bottom of the array, which already lies on the surface of the earth. It is necessary to alternately finish the rows of branches, reaching the center in order to completely clear the trunk over time. All components must be removed separately, it is best to transfer the sawn parts to the designated container during the work process.

For sawing you need to do the following:

  1. About half of the trunk is cut.
  2. Then the saw is turned off, but continues to remain in the tree. At this time, a wedge is installed in the hole obtained in the first stage, which must be well tamped with an hatchet. This must be done so that the saw is not damaged under the weight of two trunks, but is between them in an absolutely free position.

In some cases, the tire continues to remain in the trunk, especially this applies not only to large, but also to hard tree species. In this case, it makes no sense to pull out a part of the tree. It is necessary to quickly turn off the running engine, and then carry out the impact on the two sides of the trunk from the cut from below, trying to pull out the chainsaw along with it. For such an action, you need to ask your partner for help.

Safety precautions

When performing the process of felling green areas, you need to provide yourself with a complete safety technique, as well as protect the rest of the people around. Do not self-felling trees. In this case, a partner must be present. At work open fire prohibited, and if it is, then it must be extinguished without fail every time you turn on the device. Also no smoking. Care must be taken in advance about the safety of the person and wear special sawdust protection, as they always fly off when sawing wood.

Before the process of sawing a tree, you need to make sure that when it falls, it definitely will not affect people around, animals, it will not damage the cables or wires through which current flows. It is forbidden to carry out work in strong winds. It is best to determine in advance the possible fall of the trunk up to the exact contour, on which all the bars and other parts are cleared so as not to damage the tree, not to create its inertial revolution.

When working with large and thick columns, the device must be held with both hands without fail, while constantly feeling tension.

It is not necessary to carry out work when using only the extreme part of the saw, as this can lead to a strong impact and automatic stalling of the chainsaw, this can ruin the whole process of work. When sawing pillars or massive branches, you need to raise the saw to shoulder level.

Factors to consider when cutting:

  1. If the trees are of a dry type, then not only sparks from a chainsaw, but also smoke should not be allowed, since the addition of gasoline to a dry tree trunk can develop a fire. This not only slows down the work, but also brings great harm to the outside world.
  2. Before turning on the device, you need to carefully look around. There should not be children or animals nearby.
  3. Always hold the chainsaw. Even if there are malfunctions during operation and its automatic shutdown, you need to behave very carefully, since falling the chainsaw down with the sharp part can lead to disastrous consequences.
  4. The employee must be prepared in advance for the felling of forests. For starters, thick clothes and a mask are put on the face to cover the entire body from dust, dirt and dust. To get rid of the loud sound of a working device, you need to use soundproof headphones, otherwise there may be headaches due to regular and long work.
  5. The tree trunk for the worker must be a certain shield, therefore, for sawing it, the opposite side of the trunk is marked in advance.

From the very beginning, you should determine the technological features of such a process, only then plan all the stages of work, which will give you protection from the effects of the weight of the falling array. Even with many years of work in this area, you need to constantly protect yourself and pay attention to safety, since the greatest number of injuries are received by workers who have been in this field for a long time and are used to a constantly tense atmosphere.

To quickly knock down the right tree, get ready for work in advance, protect yourself by developing safety measures, only after you get to work. It is enough to independently use those positions that are included in the scheme for felling trees, so that the success of the process is guaranteed.

More attention is paid specifically to safety. To properly perform it, you need to be prepared in advance, as well as be attentive to all the work of interacting with wood.

Arrays in the forest are of great height, and very often when buying a certain site you have to cut some of the trees, so the forest is thinned out and only lonely standing species remain in it. The wind load in this case increases several times, as well as the possibility of a tree falling.

Past hurricanes suggest that it is such trees that fall very first, although they do not have any defects. During the construction of the house, you need to pay attention to the location of relatively large trees, as well as follow the usual direction of the wind. As practice has shown, trees fall precisely in the direction of the wind, even if their slope is directed in the opposite direction.
