How To Cut With A Chainsaw
How to cut a tree correctly basic rules and technology
The main aspects necessary to comply with when cutting trees:
All technological features are determined first., only then you need to clearly plan the stages of work, which will help to ensure that you protect yourself from the impact of the weight of a 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.
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 diagram and instructions.
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 is usually requires an immediate decision 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 with the selected model of chainsaw (see the 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.
Chainsaw Lesnik meets all international standards for quality and safety.
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.
Step-by-step instructions on how to cut trees
The technology for cutting large and small diameter trees has several differences. First you need to learn how to cut down small plants:
- Step 1. Looking for the slope of the tree. Even slightly gravity is suitable, however, the stronger this feature is expressed, the brighter you can notice the exact side of the fall of the plant.
A tree is considered large if it is more than half a meter in diameter. At first, the trunk is used as a support, however, the sawing of the structure can be carried out only after choosing at what angle the plant will fall. Algorithm of actions:
- Step 1. A cut is made from top to bottom with a slope of 60 degrees. It must be done exactly from the side of the intended slope. It is necessary to constantly observe the exact angle and keep the chainsaw absolutely level.
- Step 2. At the bottom, a line is drawn horizontally, which should adjoin the innermost point of the first cut. When it is carried out to the stop, you can remove the corner consisting of wood, which allows you to make a side cut.
- Step 3. On the opposite side of the first two cuts, a horizontal filing is made, which starts slightly above the lower level of the cuts on the opposite side. It is necessary to cut quite deeply, however, it is forbidden to perform the operation completely, that is, the tree must remain in an upright position.
- Step 4. In the second cut, you need to mount a pre-prepared wedge or a special blade for felling wood. The remaining volume can be removed using a spatula or by finishing from the inside.
Then the device moves in the opposite direction with a slope to the left and reaches the middle. Insert a wedge under the second notch. The tree is finished from the opposite side.
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 wood you need to make sure that if it falls, it will not affect people, living beings, will not 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.
Right answers. Circuit check
For high-quality work, only a well-sharpened chain is useful. When processing wood, it makes large sawdust and no force is applied to plunge into the material. You yourself will feel and see when it becomes dull, in particular, by the characteristic fine sawdust.
Check the tension regularly. To do this, turn the regulator until the chain slack is removed from the bottom of the tire. We take special protective gloves, lift the end of the bar and pull the chain. If it is correctly tensioned, it will not come out of the groove, but it will easily stretch from the movement of the hand.
The chain tension should be checked regularly to ensure safe saw operation. Often this is done after filling in the oil, and if you installed a new chain, then you will have to check it even more often until it is used up.
If you learn to saw correctly, working with a chainsaw becomes a pleasure. And you will save yourself and others from accidents.
If all the instructions above are followed, then you can start work. It is very important here that the operator has a firm grip on the saw with both hands. No need to slouch, but rather try to maintain balance. When tilting, you should not change the position of the body, but only bend your legs at the knees. If you need to move from one object to another, be sure to turn off the circuit.
How to saw correctly with a chainsaw
In order to start performing any type of work, whether it be working with an electric jigsaw, an electric plane or any other tool, including a chainsaw, you need to familiarize yourself with the rules, which in the future will help to ensure both the long-term operation of this device, so and will protect you from possible accidents.
How to properly cut a tree with a chainsaw safely and effectively!
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!
Sharpening and chain tensioning tool maintenance
A well-sharpened chain is a factor on which your safety, and the efficiency of the tool, and its serviceability depend. Never start work if the chain is dull, as evidenced by small sawdust and the need to apply force when cutting. The sharp chain itself bites into the tree, this can even be done when cutting trees, 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 in good working order.
How to operate a chainsaw correctly what 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 of 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 parts is completely blurry.
We will try to convey the basic safety rules to you as clearly as possible! The first rule is 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.
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 vetoesj. However, you should not cut branches that are above the shoulder. First, the tree needs to be filed for this from the side where the tree will fall, on ¼ from the diameter of the trunk, you need to cut a piece of wood at an angle of 45. 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 of the cut 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 you are sawing a fallen tree, be careful with small branches, they most often lead to a reverse impact, which is associated with almost all injuries.
The ignition system of modern chainsaws has elements that, depending on the speed of the saw, regulate the impulse. Most manufacturers today equip their equipment with electronic ignition instead of contact.
The electronic ignition system consists of the following elements:
- The electronic unit;
- Motor start button.
Magneto is a type of alternator. It supplies electrical energy to the spark plug. Any magneto consists of a coil with a core and high voltage windings, a flywheel and a permanent magnet. Magneto are contact or non-contact.
The contact magneto has two winding leads. The first goes to the spark plug, the second to the ground. A capacitor can be connected to such a circuit so that the contacts do not overheat and oxidize.
In a contactless magneto, the voltage supply regulator is a coil. The thyristor, diode and capacitor regulate the amount of current. The electrical network operates in step with the translational movement of the cylinders and the rotation of the crankshaft. However, the connection diagram of all parts of the non-contact magneto with each other depends on the saw model.
The ignition works in this way:
- A magnet attached to the flywheel rotates with it and induces an electromotive force in the system;
- A current arises in the circuit, which is converted by the electronic unit into electrical signals;
- Signals are sent to the candle;
- A spark is formed between the contacts of the plug, from which the fuel-air mixture ignites.
In any ignition, a spark is formed when the engine piston does not reach its dead center about 3-4 mm.
The candle consists of a body, an insulator and electrodes: central and side. By its condition, you can visually determine ignition faults.
After the fuel mixture ignites, the engine starts to work. The entire ignition system needs to be adjusted from time to time.
Consists of fuel filter, carburetor and manual fuel pump. At the same time, not all chainsaws have a pump: in some models, gasoline from the tank enters the carburetor unit simply through a hose. The end of the fuel filter hose is immersed in gasoline and gasoline stops flowing into the carburetor assembly when the tank is filled with air. To avoid this, a breather is attached to the tank cap: when it gets dirty, the engine stalls.
Manual fuel pump allows pre-filling the carburetor compartment with fuel, so the engine starts faster.
If the chain accidentally touches the tree during rotation, a kickback occurs. In this case, for safety reasons, the brake must be applied.
The saw brake system consists of a brake stop and a brake band. The system can be switched on in two ways: contact (the brake stop presses on the worker’s hand) and inertial (with a sharp impact on the tire, inertial forces arise that act on the brake).
How it all works
The principle of the chainsaw is simple:
- The cable is stretched, the flywheel is unwound;
- A fuel-air mixture is prepared in the carburetor;
- The engine starts;
- After releasing the chain brake, the chain is released from blocking;
- Single-stage chain drive drives the chain.
The starter starts the engine of the chainsaw. The starter mechanism consists of a handle, rope, drum and return spring.
If you sharply pull out the handle with the torso, the drum will engage with the shaft, the shaft will begin to spin. The spring will help return the handle to its original position. To start the motor after turning the shaft, you will need to pull the handle more than once.
Chain pitch is an intermediate distance between three rivets located side by side.
But chains with a small pitch (more teeth and less distance between them) vibrate less, their movements are smoother when cutting, and the cut is cleaner.
Chainsaw tires vary in length. Bar length The length of the bar, that is, the distance from the front of the saw to the rounded tip of the bar nose. As a rule, the length of the tire is indicated in the instructions.
But the reliability of a guide bar is determined not only by its own characteristics, but also by other details. For example, an asterisk. If the sprocket is made of durable materials, the tire will last a long time. Due to the replaceable crown, the runout level is reduced many times.
In order for the tire wear to be the most uniform, it must be turned over periodically, then the service life will increase.
How the chainsaw works
The chainsaw device is not too complicated. The main elements of its construction:
- Ignition system;
- Fuel system;
- Air purification system.
Let’s talk about each of them in more detail.
