Chainsaws instructions for use and operation. Chainsaw device and important rules for handling gasoline tools. Chainsaw maintenance

A chainsaw greatly simplifies the process of sawing wood, but it is worth remembering that this tool is a source of possible accidents. When buying a new tool, the chainsaw instruction manual is mandatory in the kit. It must be studied by everyone who first starts working using this tool. This will not only prevent the occurrence of breakdowns during improper operation, but also eliminate the possibility of accidents.

Chainsaws, regardless of the model, have common nodes that may differ in shape and configuration:

• engine;
• clutch;
• reducer;
• saw machine;
• directly frame and starter controls.

Getting started with a chainsaw

Most men immediately after buying a chainsaw want to test it in practice, while forgetting to read the user manual. Manufacturers strongly recommend that you initially read the instructions, which will help you set up the tool and bring it to working condition. Otherwise, there is a high probability that the tool will receive irreparable damage during the first use.

Before starting the first work with the tool, you need to set up the bar, chain and sprocket. All these elements must work together. When using the saw for the first time, it is very important to break in the engine, for this it is worth emptying one tank. It is important not to load the saw, but it is also not worth doing idle turns. Such actions can result in significant engine wear.

The first thing it starts with is bringing the tool into the on mode. Before starting the tool, it is worth pumping up a little fuel into the carburetor. Then you should pull out the choke and pull the starter with a sharp jerk. If the starter jerks are not sharp, but sluggish, there is a chance to fill in candles, and all subsequent attempts to start the chainsaw will be reduced to zero. If this happens, it is necessary to pull out the candle and warm it up, as a result of which all vapors of the fuel mixture will evaporate.

1. It is very important to hold the tool with both hands, firmly holding on to the handle. In this case, the thumb of the left hand should be located under the front handle.
2. When performing work, do not stand behind the tool. The worker should position himself to the side of the appliance.
3. Sawing is carried out by the upper or lower edge of the saw. If the cut is made with the upper edge, then the saw is moving towards the worker, and this is very important to consider during work.
4. When working, it is better to stand with a flat back and legs half-bent at the knees, this position will provide maximum balance.
5. It is extremely dangerous to move with the tool turned on, so if there is a need to move to another place, the tool should be turned off or put on the brake.
6. It is worth starting the cut with the edge of the tire located closer to the body.

Chainsaw operation at different times of the year

The two-wheel internal combustion engine that powers the chainsaw requires some care in different seasons. If work is done outdoors in winter time and the temperature is below zero, it is very important to warm up the carburetor. This is necessary because the fuel at such low temperatures can crystallize, making the mixture more viscous. Warming up the carburetor allows the saw to adapt to such a temperature regime.

It is also worth paying attention to the abrupt change temperature regime. If the instrument has been stored in a cold place, do not abruptly bring it into a warm room, as condensation will immediately form. This accumulation of moisture inside the tool can cause negative consequences associated with the phenomenon of corrosion.

Chainsaws help to quickly and efficiently clear the space of trees, build log cabins or harvest wood raw materials. But in order to work correctly and safely with this tool, it is useful to know what is inside it.

How a chainsaw works

The chainsaw device is not too complicated. The main elements of its design:

• ignition system;
• carburetor;
• fuel system;
• air purification system.

Let's talk about each of them in more detail.

Ignition system

In the ignition system of modern chainsaws, there are 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:

• magneto;
• candle;
• the electronic unit;
• wiring;
• engine 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 type magnet. Magneto are either contact or non-contact.

The contact magneto has two winding leads. The first goes to the spark plug, the second goes to the ground. A capacitor can be connected to such a circuit so that the contacts do not overheat and oxidize.

In a non-contact magneto, the voltage supply regulator is a coil. The thyristor, diode and capacitor regulate the amount of current. The electrical network functions in time with the translational movement of the cylinders and the rotation of the crankshaft. However, the scheme for connecting all parts of a non-contact magneto to each other depends on the saw model.

The ignition works like this:

• 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 transmitted to the candle;
• a spark is formed between the contacts of the candle, from which the fuel-air mixture ignites.

In any ignition, a spark is formed when the engine piston does not reach its "dead center" by about 3-4 mm.

The candle consists of a body, an insulator and electrodes: central and lateral. By its condition, it is possible to visually determine ignition malfunctions.

After the ignition of the fuel mixture, the engine starts to work. From time to time the entire ignition system needs to be adjusted.

Carburetor

On most models of chainsaws, carburetors are arranged in the same way.

They have a shutter in the body. With its help, both screws (main and idle), diffuser, impulse channel and inlet fitting are regulated. The damper also regulates the supply of atmospheric air.

Understanding how a carburetor works will help you make proper adjustments. It works like this:

• the engine starts, the air damper opens in the lower part of the housing;
• a vacuum occurs inside the float chamber and in the air channel because the piston moves;
• air is sucked in through the diffuser;
• fuel mixture enters the float chamber from the gasoline tank through the fitting;
• in the diffuser, gasoline is mixed with air;
• The air-fuel mixture enters the combustion chamber through the intake ports.

With the help of a damper, you can adjust the intensity of air entering the fuel, with the help of screws - adjust the engine speed, with the help of a jet - the speed of gasoline entering the diffuser.

Fuel system

It consists of a fuel filter, a carburetor and a manual type fuel pump. At the same time, not all chainsaws have a pump: in some models, gasoline from the tank enters the carburetor assembly simply through a hose. The end of the hose with the fuel filter 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.

The manual type fuel pump allows you to pre-fill the carburetor compartment with fuel, so the engine starts faster.

Chainsaws are equipped with a pre-filter and a fine filter system to ensure that the gas used to make up the fuel-air mixture is of good quality.

The air is pre-filtered by a mesh filter, then by fine filters.

Due to clogged filters, less air enters the carburetor assembly. As a result, the power of the motor drops. To prevent this, the filters must be constantly cleaned: blown or rinsed.

Starter

The starter starts the chainsaw motor. The starter mechanism consists of a handle, a cable, a drum and a return spring.

If you sharply pull the handle with the torso, the drum will engage with the shaft, the shaft will begin to scroll. The spring will help return the handle to its original position. In order for the rotation of the shaft to be followed by the start of the motor, it will be necessary to pull the handle more than once.

Chain

Chain pitch - the intermediate distance between three rivets located side by side.

The larger the chain pitch, the greater the power of the engines, and its performance, and the efforts made to increase the rotation of the drive sprocket.

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.

Tire

Chainsaw tires vary in length. Bar length - the length of the working part, that is, the distance from the front of the saw to the rounded tip of the nose of the bar. As a rule, the length of the tire is indicated in the instructions.

But the reliability of a saw bar is determined not only by its own characteristics, but also by other details. For example, an asterisk. If the sprocket with a replaceable crown is made of durable materials, the tire will last a long time. Thanks to the replaceable crown, the level of runout is reduced many times over.

In order for the tire to wear the most evenly, it must be turned over periodically, then the service life will increase.

Brake

If the chain accidentally touches the tree while it is spinning, it will kick back. In this case, for safety reasons, the brake must be applied.

The brake system of the saw consists of a brake stop and a brake band. There are two ways to turn on the system: contact (the brake stop presses the worker's hand) and inertial (with a sharp blow to the tire, inertial forces arise that act on the brake).

Chain lubrication system

In modern chainsaws, the chain and bar are automatically lubricated. There is no oil supply at idle, since the oil pumps only start working after the sprocket has rotated and the gear has started to move. The more revolutions of the sprocket, the more oil flows from the pump to the chain. The pump is installed from the side of the chain, oil enters it from the oil tank through the oil pipeline.

Tools used:
chainsaw Makta DCS 7900 (professional);
chainsaw Makta DCS 3435 (amateur).

Those who do not yet have experience using a chainsaw should remember the basic principles of working with this tool:

- the saw must be held with both hands, and the handles must be clasped with all fingers. In this case, the thumb of the left hand should be under the front handle;

- when working, you can not stand directly behind the saw, you need to stand slightly to the side of the tool;

- you can cut both the upper and lower edge of the tool. When sawing with the bottom edge, the chain guides the saw away from the user. When sawing is performed with the top edge of the tool, the chain moves the saw towards the user;

– when moving to another place, it is necessary to turn off the tool engine or activate the saw brake. It is impossible to move with a saw whose chain rotates;

- you need to start sawing with that part of the tire that is located closer to the tool body;

- if you plan to work frequently with a chainsaw, you need to purchase protective clothing: durable boots (preferably special, protected by steel plates), strong gloves, special trousers with cut protection, a bright protective jacket that allows air to pass through, and a helmet with a mask.

1. Preparation for work

Before starting work, check the chain tension - it must be carefully adjusted so that the chain does not sag on the tire during operation. A loose chain will wear the bar and sprocket faster, damage the shock absorbers faster, and increase the load on the tool body.

- before starting to work with a chainsaw, you must definitely read the user manual;

– if the saw chain is new, it is recommended to immerse it in oil for several hours before starting work. If the chain is old, it is imperative to sharpen it: the cutting tools of a poorly sharpened saw wear out quickly.

The saw is placed on a stable surface and refueled. For refueling, use only “branded” oils designed specifically for chainsaws. The percentage of oil in this mixture should be 1/40-1/50. For the operation of imported saws, it is better to use the 92nd gasoline (or higher brand), and the 76th is also suitable for Russian ones.

– to avoid the risk of fire, before starting the engine, the saw is removed from the place where it was filled with fuel and placed again on a solid, stable base.

3. First launch of the tool

After checking that the chain does not touch hard surfaces, turn on the chain brake. At the same time, the brake handle is moved away from you so that the chain does not start to rotate ahead of time. Since the engine is cold, the choke control lever is pulled out fully. The toe of the foot is threaded into the rear handle (while holding the front handle with your hand). Pull the handle several times, pulling the starter cord until the engine "sneezes". After that, the air damper is transferred to the working position and the saw is started. Briefly press the throttle, switch the saw to idle. The brake lever is returned to its original position. The saw is ready to go.

– Check the tool brake before starting work. To do this, place the saw on a flat surface and press the throttle. The brake is activated by pressing the handle without releasing the handle of the tool. If the chain has stopped, then the brake is working properly;

– also check the lubrication mechanism before operation. You need to find some light surface (for example, a freshly cut stump). Holding the tool over the stump, you need to start the chain and increase its speed by pressing the throttle. If a streak of oil appears on the hemp, then the lubrication mechanism is in order.

4. Pruning branches

Trimming branches from the trunk of a fallen tree begins from the bottom of the trunk, standing to the left of it. Work is carried out at a slow, calm pace, trying not to use the nose of the saw. They saw both the upper and lower parts of the tire, trying to lean the saw against the thigh or the trunk if possible. The branches from the top of the trunk are cut down, putting the tool on its side (the saw should lie on the trunk with all its weight). After the branches on top and on the side of the lying trunk are cut off, the trunk is turned over and the branches that were below are cut off.

- it should be remembered that sometimes the entire trunk can rest on only one branch: if it is cut, the trunk may move or roll;

- if the branch is thick, it must be cut in parts - from the end to the trunk. With a particularly large thickness of the branch, it may be necessary to file it from both sides.

5. Bucking (cutting the trunk into pieces)

Crossing is started when all the branches are cut from the trunk. The trunk of a lying tree is sawn into pieces in the direction from the trunk to the top (butt).

- in the process of bucking, it is forbidden to stand below the trunk if it is located on an inclined plane;

– if the saw is stuck in the trunk, you need to stop the engine and tilt the trunk until the saw comes out of the wood. You do not need to immediately get the saw out of the tree.

6. Felling trees

Before cutting down a tree, it is determined in which direction it will be “more convenient” for it to fall. To do this, the natural slope of the trunk, the direction of the wind and the number of branches on each of its sides are taken into account. The tree must be felled in the direction in which it is "more convenient" for it to fall. Just before felling, you need to cut low branches that can interfere with work. There are several technologies for felling trees, which are selected depending on the thickness of the trunk and other factors. Pick up best way only a professional lumberjack can.

– if there are people nearby, they should be at least 2 tree trunk lengths away;

- before starting work, make sure that there is nothing around that could be damaged by a fallen tree;

- felling trees is not an easy task: if there is no experience of such work, it is better to entrust this matter to professionals or ask them to be present at work!

Tool Care

Every time after working with a chainsaw, you must perform the following steps:

1. Check chain tension and lubrication.

If the chain is loose, it must be tightened; if the oil runs out, add it to the tank.

Fill the machine with fuel at the end of work after a short rest so that the saw cools down.

3. Checking the air filter.

Periodically, the filter becomes clogged with chips - after finishing work, it is advisable to remove it, rinse and blow it out. Also periodically it is necessary to clean the surfaces around the engine cooling plates from contamination.

A chainsaw is an excellent tool for cutting wood, featuring high performance and reliability. But before you start working with it, you must carefully read the attached instructions and perform a number of preparatory operations. They will help to avoid damage to the unit and ensure its safe operation. Given here helpful tips when working with chainsaws are based on the recommendations of equipment manufacturers and the experience of professional craftsmen.

If you have studied the operating instructions for the chainsaw, and you have figured out the location and principle of operation of all its nodes, you can begin to prepare the first run of the tool. First, by external inspection, they are convinced that the chainsaw is complete and that there are no visible damages. The guide bar must be fixed in place, and the cutting chain inserted into its grooves and engaged with the sprocket.

It is important that the chain has the optimal tension. If the seat is too tight, the load on the engine will increase, and loosening of the engagement can lead to disengagement and jamming of parts. To check, pull the chain in the middle of the bar up. At the same time, its shanks should come out of the groove by a few millimeters. If this does not happen or there is a strong sag, the position of the tire must be adjusted.

Filling with fuel mixture and chain oil

In accordance with the manufacturer's recommendations, a fuel mixture is prepared from gasoline of the specified brand and oil for two-stroke carburetor engines. The ratio for most foreign models is 1:40 or 1:50. Fuel is poured with the fuel tank cap removed, marked gas station icon. Separate chain lubrication system marked picture of a drop, filled with machine oil type W30-W40.

Often, manufacturers advise using their own brands.

First start of chainsaw

A new chainsaw cannot be immediately operated under maximum load. All rotating parts of the tool must first rub against each other. It is recommended to operate a full gas tank at the first start without applying much effort to the saw.. If such a test is successful, you can subsequently cut with a chainsaw without additional restrictions.

The chainsaw is launched on flat horizontal ground. The starting order using the example of a Stihl saw should be as follows.

1. Pull the chain by hand along the bar, making sure that it runs smoothly and that there is no excessive resistance.
2. Engage the chain brake by pulling its handle away from you.
3. Open the cylinder decompression valve.
   
   
4. Few clicks on the primer to apply the fuel mixture to the carburetor.
   
   
5. To properly start the saw, you need to press the rear handle with your right foot to the ground. Holding the front handle with your left hand, fix the fuel supply lever in the working position with your right hand.
   
6. Set the combination switch to the cold start position.
7. With a jerk of the starter handle, start the ignition of the engine, which should almost immediately stall.
   
8. Open the throttle to the half throttle position.
   
   
9. By jerking the starter cable again, start the engine again, immediately switching the fuel feed lever to the idle position.
   
10. Pull the chain brake handle towards you, moving it to the working position.
11. Bring the far end of the guide bar to a clean and bright surface, make sure that the chain lubrication system works by spraying small drops of oil.

After making sure that all the components and mechanisms of the saw are in good condition and do not emit extraneous noise at idle, you can proceed to work under load.

Chainsaw Safety Precautions

When purchasing such a tool, you need to know how to properly use a chainsaw. Occupational safety requires the employee to use only serviceable equipment. Therefore, the operation of a chainsaw requires:

• mandatory inspection before each launch;
• regular checks of the status and adjustment of the main nodes;
• timely addition of oil and regulation of chain tension;
• stopping work when a malfunction of the chain brake and other critical parts and devices is detected.

Do not make homemade changes to the design of the tool or use spare parts that are not suitable for the model being used. Some craftsmen talk about how to start a chainsaw without starter. But they forget that its impeller is necessary to cool the motor, which will begin to overheat with the threat of failure.

You can only work with a chainsaw in overalls using special gloves, shoes with metal inserts, helmets and eye protection. In this case, the tool is held with two hands with a straight back, without leaning far forward and without lifting the saw above the shoulders. It is not recommended to place body parts in the cutting plane. Safety measures prohibit moving with a chainsaw in which the cutting chain rotates.

Practical work with a chainsaw when felling trees and cutting branches requires special rules to prevent injury to the worker from falling trunks. Especially dangerous is the reverse blow with a saw that has stumbled upon an obstacle. The lumberjack cannot:

• fell trees in one cut;
• cut several branches at the same time;
• cut with the end of the tire;
• be in the area where the tree fell.

Chainsaw maintenance

Chainsaw care includes:

• keeping clean and dry;
• timely adjustment of all components and assemblies;
• replacement of worn parts with new ones.

It is necessary to regularly service the chainsaw by performing the following operations:

• adding fuel mixture and oil to lubricate rubbing surfaces;
• adjusting the tension of the chain, which lengthens over time;
• lubrication of the driven sprocket of the tire;
• blowing or washing the air filter;
• cylinder combustion chamber cleaning;
• replacement of the chain, guide bar and drive sprocket due to abrasion of more than 0.5 mm from the nominal dimensions.

All maintenance work on the chainsaw is carried out only with the engine turned off.

If it is necessary to stop work for a long time, all chainsaw units are thoroughly cleaned. In this case, the metal parts are covered with grease, and the chain is removed and immersed in oil. Fuel must be drained. It is recommended to store such a tool in a warm and dry place.

Following the guidelines listed in this article will help you operate your chainsaw efficiently and safely for the life specified by the manufacturers.

After buying a chainsaw, the owner can not wait to try it out as soon as possible.

It is good if he already has the skills to maintain and safely operate this tool. If there is no such experience, then one should not rush with the first launch.

Spending a little time learning how to prepare a chainsaw for work, understanding how to handle it safely, you will protect yourself from injury and extend the life of your mechanical assistant.

Tips on how to properly use a chainsaw are divided into four groups:

1. Preparation.
2. Launch.
3. Work practices and safety precautions.
4. Service.

In this order, we will consider them in our article.

Tool preparation

A chainsaw is a motorized tool based on a two-stroke internal combustion engine. It cannot run on pure gasoline, so a gasoline-oil mixture must be prepared to start.

Its proportion is simple: for 1 liter of gasoline of a brand not lower than A92 (for expensive imported chainsaws, a brand not lower than A95) we take 20 grams of special engine oil for chainsaws. In the instructions, this proportion is designated 1:50. Having mixed fuel and oil in a plastic container, open the filler neck and fill the tank with a combustible mixture.

For beginners, we advise you to be careful not to confuse the fuel filler neck with the chain oil filler neck. On some models of chainsaws, they are both located on the same side of the body. You can distinguish them by a special marking applied next to the hole. You will see a gas station icon on the fuel filler neck. A drop symbol is applied next to the oil filler neck.

Good chain lubrication is an important condition for the quality operation of the chainsaw and the long life of the saw bar. The chainsaw operating instructions recommend using only the manufacturer's branded oil. In addition to it, it is allowed to fill in high-quality automotive engine oil with a viscosity of W30-W40. We do not recommend using dirty mining and other oil surrogates to lubricate the chain.

The mark to which chain oil is filled into the tank is always located near the filler neck. When working with a chainsaw, do not forget to periodically glance at it so as not to miss the moment of replenishing the tank. In addition to the saw chain, occasionally (once a month) the bar bearing located on its outer end part should be lubricated. Some tires have a special hole there, into which a few drops of oil are sprayed with a syringe. Refueling the saw should only be done on a horizontal hard surface.

chainsaw start

After filling the fuel mixture and chain lubrication, you can proceed to the second stage - starting the chainsaw. Here you will also need the manufacturer's instructions.

It briefly and clearly describes the main stages of this operation:

1. Checking the chain tension (pull the upper middle links) . If they give in with some effort, it means that the chain is tight enough. If the saw chain sags, then you need to use the tensioning mechanism and tighten it.
2. Pulling the chain along the bar . Under normal tension, it rotates easily. If you overtighten the chain, then you need to loosen it a little. Along the way, we look at the position of the chain brake (a wide plastic shield next to the front handle). It must be turned on (pressed forward from the front handle that holds the saw). At idle, when the engine is warming up, we don't need the chain to turn. So we put it on the brakes.
3. Set up the chainsaw on a level surface . Hold the front handle with your left hand. We put our right foot on the rear handle, turn on the ignition button, push the throttle and sharply pull the starter handle several times. As soon as the engine gives the first “flash”, we close the throttle and again sharply pull the starter handle until the engine starts.
4. Disengage the chain brake, making sure that there are no foreign objects under the saw chain , which she can pick up, and press the gas a couple of times to warm up the tool.
5. Check the supply of lubrication to the chain. To do this, we bring the saw to any light object (a sheet of paper, a board, a cut of a stump). If a trace of oil appears on it, then the lubricant is supplied to the chain in sufficient quantities.

The starting procedure described above is carried out on a cold engine. If the saw has already worked for some time and was muffled, then its start-up is done by the starter handle without using the throttle.

Rules of work and safety precautions

A chainsaw is a dangerous tool. This fact should not cause panic fear. It is designed to encourage the owner to constantly monitor their actions during work.

So, what does safety require when working with a chainsaw?

First, do not spare the money to buy a set of workwear (gloves, a protective helmet, a suit and special shoes). He will become reliable protection from damage.

In particular, gloves for such saws protect fingers well from injury. Their fabric, upon contact with the chain, wraps around it and blocks it, saving fingers from sharp teeth. A protective helmet will prevent wood chips from damaging your eyes and protect your head from falling branches.

The lumberjack's shoes are equipped with steel plates. In the event of an unexpected rebound of the saw, they take on the cutting blow.

Second, don't hold the saw straight ahead of you. Hold it so that your feet are on the side of the cut line.

Third, hold the saw firmly with all fingers wrapped around the handles. In this case, the right hand must be kept on the back handle, and the left hand on the front.

These three basic rules need to be supplemented with other equally important points:

• Carefully insert the running saw into the cut you have made.
• Beware of sawing with the tip of the bar (high chance of kickback).
• Remove from the work area all foreign objects that can trip and fall.
• When cutting, do not lean too low to avoid losing your balance.
• Do not work holding the chainsaw above your shoulders.
• Do not hold the tool too far away from you so that your back and arms do not strain and get tired during long work.
• The back should always be kept straight and the legs wide apart.
• The cut can be made on both sides of the bar. It should be borne in mind that when cutting with the lower edge, the chain pulls the saw forward, and when working with the upper part, it pulls the saw back.
• Before moving the saw to a new place of work, stop the engine or put the brake on the chain (idle).

A good rule of thumb is not to work alone, but with a partner who can provide first aid.

Before cutting a tree, you need to stand to the right of it and perform a notch (at an angle of 45 degrees to a depth of no more than ¼ of the trunk diameter). The saw cut is made from the side of the fall of the tree (the direction of the natural inclination of the trunk). After that, a horizontal undercut is made on the other side - the main felling cut. It is not brought to an inclined notch by a few centimeters so that the tree does not collapse ahead of time (Figures 1 and 2).

To avoid clamping the saw bar in the main cut, a wooden wedge is inserted into it.

Rice. No. 1 scheme for cutting the barrel with a chainsaw
Rice. No. 2 (1, 2 - upper and lower notches, 3 - main felling cut)

When working, you need to monitor where the barrel moves. This rule will help you avoid serious injury if the barrel falls in an unplanned direction.

When the tree begins to fall, you need to quickly remove the saw from the cut, turn off its engine and leave the work area.

Having knocked down a tree, one should not relax, since statistics fixes the main number of injuries precisely at the stage of pruning branches.

To perform this job safely, follow these rules:

• fix the barrel with linings so that it does not move or roll;
• stand to the left of the fallen tree, and start cutting from the lower branches;
• cut thick branches, starting from their end and gradually moving towards the trunk.

If the chainsaw is stuck while sawing a fallen tree, do not pull it to try to remove it. First, turn off the motor and use thick levers to try to raise or tilt the trunk to widen the cut.

Tool maintenance

This is an indicator of the professionalism of the owner. If timely and high-quality care is organized for the chainsaw, then it will work reliably and for a long time.

After finishing work, the tool must be cleaned of sawdust and debris. Don't forget to check the chain tension and oil level. Proper maintenance of the chainsaw involves regularly checking the condition of the air filter. If you do not monitor its cleanliness, then you are guaranteed problems with starting.

The chain, the tire and its drive sprocket wear out the fastest on this tool. Therefore, their condition also needs to be constantly monitored.

If there is fuel left in the tank, then it must be drained into a separate container. The manufacturer's instructions recommend producing the prepared mixture within 2-3 weeks.
