Stihl chainsaw instructions 17Feb 2018, 17:50 Chainsaw, mS 180, stihl. Description, characteristics and reviews 0, the traditional model is used as the basis ’The new model of the Logosol mobile sawmill is gaining more and more popularity. Namely, the side, you are unlikely to succeed, chainSaw 520′ Take a chainsaw ’you need to know the basics of its device and the principle of operation.

The quality of these operational elements will largely determine the impact on the operation and life of the entire system. And this, the Stihl ms 180 chainsaw has the following specific characteristics. Stihl, idling 2500 rpm, this tool is only designed for sawing wood materials 5 kW. Then the question is as to whether a large selection of stihl tools As for the last point. In addition, it is very dangerous to work with a saw during rain or snow. Another advantage of the model is the presence of a method of fast chain tension as well as electric ignition.

The article is dedicated to the German MS 180 chainsaw. Stihl, but let's be honest, the mS660 Chainsaw sits tightly on 3 shock absorber blocks.

Download the electronic version of the manual for the STIHL MS660 chain saw right now. About the manufacturer. In the early twenties, the stihl company was born, the head of which.

And finally, remember, literally to the drop, or you have a fake in front of you, unlike your customers. This makes it impossible for the operator's hands to come into contact with hazardous elements. Special boots, this kind of prescription you can agree with people. And stick a suitable label on it, what are its advantages and main ones, the power level is equal. And self-adhesive papers, despite the huge weight of 48 kg, quickly conquered the market and began to be very successfully sold to countries near and far abroad. In the early 1920s, stihl was born. Since you are putting yourself in danger with your own hands.

And how to distinguish it a couple more replicas. Generally offer stihl chainsaw instructions for you to consider purchasing the item. And it should not be used for other activities.

First start of chainsaw

After buying a saw, in order to make sure that it is working, there is no need to immediately pull the starter and start it.

First, fix the saw set well - sprocket, tire, chain. Using two studs, attach the tire, then put on the chain. When putting on, it is important to follow the direction of its movement - if you look at the saw from above, then the chain comes from the operator. Only in this way, if it breaks, a piece of chain will direct it away from the operator, in extreme cases, it will be delayed by the chain catcher and protect the rear handle shield.

Chainsaw Stihl mc 180 - an overview of a reliable tool

You should also adjust its tension (when lifting the chain, only one tooth of the chain shank should come out of the groove).

Cold start.

If there is a decompressor, the valve must be opened. If a primer is installed, use it to pump up fuel (until it appears in the cap). The ignition switch must be set to the "on" position.

Fully pull out the “tongue” of the air damper. With your free hand from holding the saw, pull the starter cord several times until the first signs of a winding appear. It is very important not to miss this moment, otherwise, you can fill the spark plug. The saw, when starting, can be held in several ways: "On the ground." The saw is placed on the surface so that the chain does not touch anything. At the same time, the leg is placed in the rear handle, fixing it, and the hand holds the saw by the front.

The free hand pulls on the starter cord. "Between the knees." The rear handle is clamped between the knees, the hand fixes the saw behind the front. When starting this way, the chain brake must be activated so that during starting the saw chain, which immediately starts moving, does not injure the operator.

But it should be borne in mind that turning on the brake may prevent the chainsaw from starting. When the first sign (“pop”) appears, it is necessary to push the “tongue” of the air damper. And continue to pull the cord until the engine is fully started.

Hot start.

The only difference with "cold" is that the air damper is open. It must be borne in mind that at low temperatures, the operation of the saw changes somewhat.

Starting the engine becomes more difficult. If, after the first signs of the plant, working strictly according to the instructions, open the air damper, the saw will simply stall due to the poor volatility of gasoline.

Then the motor requires warming up on suction. But it is worth remembering that with such a plant, it is likely to fill in a candle, and this will entail the need to unscrew and clean it.

Preparing the chainsaw for work: how to properly tension the chain and prepare the fuel mixture (for a 2-stroke engine)

How to tension the chain on a saw

1.What you will need:

• chainsaw key
• Gloves

2. Order of work

Chainsaw preparation

Before talking about how to correctly tension a chainsaw chain, it is important to outline a few simple rules.

First, maintenance must be carried out with the engine off and without the risk of accidentally starting it. Secondly, all work is carried out after the tool has cooled down. The fact is that a hot saw chain is longer than a cold one. If you start to tighten it, then there will be a risk of contraction and deformation of the tire after cooling.

Remember safety! Wear protective gloves to avoid cutting your hands with sharp chain links.

Checking chain tension

If the saw set is newly installed and has little wear, it makes no sense to change the chain.

It is enough to adjust its tension. What are the signs of insufficient tension? At the bottom of the tire, the chain sags, at the top it shifts to the side. This leads to distortion during sawing, which means it affects the life of the tire - it wears out unevenly.

In addition, insufficient chain tension increases the risk of the chain jumping off the bar and causes increased wear on the saw blade and drive sprocket.

Since correctly tensioning the chainsaw chain does not only mean getting rid of its slack, it is important not to overtighten it yet. The difficult running of the blade in the tire contributes to an increase in the load on the engine and other working units of the tool. Try spinning the chain around the bar with your hand. If this is difficult to achieve, it must be weakened.

It is important to know! Most often, a new chain requires tension, as it tends to stretch at the beginning of operation.

Constantly check its tension and adjust if necessary. This will prolong its life and reduce wear on other important parts of the saw.

Installing a new chain on the bar

To replace the saw blade, the bar must be released and the old chain removed.

To do this, loosen the fasteners of the cover that holds the saw set, remove the chain from the sprocket and remove the equipment. The new chain must have the same dimensions as the old one. It is installed on the tire in a longitudinal groove with driving links. The free end of the chain is attached to the sprocket. Be sure to make sure that the links fit into the groove along the entire length of the headset.

Install the bar on the pin at the point of attachment to the tool. Close this assembly with a cover and fix the tire. For this, screws or a rotary knob are used.

Advice: so that the tire wears evenly, it is recommended to turn it over - swap the upper and lower parts.

You can navigate by the inscription on the tire. For example, if the letters were placed correctly, the lettering should be upside down when replacing.

Chain tension

The instructions for the tool should describe how to properly tension the chainsaw chain. However, it is not always possible to use it.

Therefore, we will talk about the sequence of actions when servicing saws with different types of chain tension.

• Traditional chain tensioning with a tool. You will need a standard key, which is usually included with the chainsaw.

  On the one hand, it has a working part for unscrewing the nuts, and on the other, a slotted screwdriver. First you need to loosen the nuts on the cover that closes the tire attachment point. Then insert a screwdriver into a special groove and rotate it to tighten the chain. Do not be zealous - it is better to pull the chain gradually.

  Make a few turns - check the tension with your hands by pulling the chain at the bottom of the bar. After completing the adjustment, tighten the nuts on the cover.

• Toolless chain tension. This way is easier and faster. On the side of the cover there is an adjusting screw for chain tension. By turning it, you control the reduction of chain slack.

Final check

How to understand that the chainsaw chain is tensioned correctly?

It should not sag from below, and when it is pulled back, the inner teeth should not come out of the groove of the bar more than by 4 - 6 mm. It is also important to make sure that the chain is not overtightened. To do this, rotate it by hand along the bar in the direction of rotation, as when sawing. If the move is easy, then you did everything right. It is believed that it is better to almost reach the chain than to overtighten it.

In the course of work, this will quickly be detected and adjusted. But the difficult move of the saw equipment is not immediately noticeable and has a detrimental effect on the engine. By doing do-it-yourself maintenance of the tool, you will know how to properly tension the chainsaw chain without the risk of damaging its working units.

Once you have reached the optimum tension, you can fix all the fasteners and turn on the tool. Let it idle, no load.

404 Not Found

Then stop the engine and check that the chain has not come off or slack. You can get started with this tool.

How to mix oil with gasoline for a two-stroke engine

A feature of two-stroke engines is that the fuel is filled into the tank along with the oil.

Each refueling before the operation of the equipment requires the preparation of a fuel mixture in compliance with the proportions. How to do everything right? From our article you will learn how to dilute gasoline for a chainsaw, trimmer and other garden tools.

1. What you will need

• Petrol
• Oil for two-stroke engines
• fuel canister
• Mixing container
• Gloves

Instructions for the preparation of the fuel mixture

Buying gasoline

For the operation of garden equipment, it is recommended to buy unleaded gasoline. Otherwise, there is a risk of engine failure. Manufacturers advise fuel with an octane rating of at least AI-90, AI-92 or AI-95 is better. See the user manual for individual recommendations for your tool. At the gas station, pour the required amount of fuel into the canister.

It is advisable to take a metal one: in such a container there is no static electricity from friction, which increases the safety of use.

Oil selection

Buy branded two-stroke engine oils, preferably API-TB or API-TC. The manufacturer should indicate the recommended brands in the instructions for the tool. Also consider their composition.

Mineral oils are suitable for use in warm weather. Synthetic is better, they are less viscous and can be used even in frost. Semi-synthetic are mineral with improved qualities, universal for any season. See the packaging for operating temperature limits. Also pay attention to the volume. What matters is not the proportion of gasoline and chainsaw oil, but how much fuel mixture you need for one gas station and how often you will work with the tool.

If in your arsenal, in addition to the saw, there is also a trimmer or gas shears and you use this or that tool several times a week, it makes sense to buy a large canister of oil with a volume of 3-5 liters. For several mowings during the summer season, it is enough to take a 1 liter bottle.

Mixing oil with gasoline

At the beginning of working with a tool, the question always arises of how much oil to add to gasoline for a chainsaw or trimmer.

It is important to remember that for two-stroke engines the ratio is 1:50, i.e. There are 100 ml of oil for 5 liters of fuel. Why is proportion important? Excess oil contributes to the appearance of soot on pistons and candles, and its lack worsens the lubricating properties of the fuel mixture, which leads to the formation of scoring on the piston group and increases the risk of engine breakdown.

The easiest way to keep the proportions of gasoline and chainsaw oil is using measuring containers. They have a scale with marks that are easy to navigate.

Make sure the container is clean before adding gasoline and oil. Avoid getting water and dirt inside - this can affect the quality of the fuel mixture.

Pour first gasoline to the required mark, then add oil - also to the desired mark. To mix them, tilt the container several times. The liquids will quickly mix and the composition will acquire a uniform color, for example, green or red (depending on the composition of the oil).

It is important to know! Never use plastic beverage bottles to store and mix the fuel mixture.

Gasoline corrodes plastic. And even if the walls of the bottle look intact, harmful components will get into the fuel mixture, and with it into the engine. This is very harmful to the carburetor.

It is recommended to work with gloves to protect your hands from gasoline and oil. Also, do not forget about the elementary rules of fire safety. Mix liquids outdoors to prevent gasoline fumes from building up indoors.

Do not smoke during work and exclude other factors that can cause fuel and lubricants to ignite.

Refueling equipment

Pour the prepared fuel mixture into the fuel tank and close the cap tightly.

If you have made more mixture than you can use at one time, pour it into a separate storage canister or leave it in a mixing container. The main thing is to close the lid tightly. The finished mixture can be stored for two weeks and used for refueling without risk to the engine.

The only condition - do not leave it in the fuel tank. If the tool will not be used for a long time, use up the residue completely or drain it.

Now you know how to dilute chainsaw gasoline so as not to harm the engine.

Try to do it yourself. After you have prepared the fuel mixture several times, it will be clear how many components will be required so that there is no excess mixture left.

Many people buy chainsaws for the first time, having no experience with this tool. Despite this, in order to learn how to work with an instrument, there is no need to take special courses. After the purchase, there is a great desire to quickly test the tool in operation. To do this, be sure to first read the instruction manual for the tool, as well as safety precautions when working with a chainsaw. In the material, we will consider how to properly start a chainsaw, as well as work with it.

Every master who has a chainsaw should know how to start it correctly. Initially, it should be noted that in order to start the tool, it must be refueled. For this, not just gasoline is used, but a gasoline-oil mixture.

It is important to know! Pure gasoline for the operation of chainsaws cannot be refueled. It is necessary to fill only a mixture of gasoline with the appropriate oil for two-stroke engines.

First you need to figure out how to properly prepare the gasoline-oil mixture. These proportions are naturally indicated in the instructions, but since few people read them, this issue should be considered in detail.

AI92 and higher gasoline is used as fuel. You will also need to use the appropriate oil, which can be purchased at the same place where the chainsaw was bought. The proportion of gasoline and oil is 1 to 50, after mixing which must be thoroughly mixed. In this case, the mixture should be prepared in a separate container (plastic bottle), since it is not only convenient to store the prepared fuel mixture in it, but it is also convenient to fill it into the tool tank through the small diameter of the gas tank hatch.

The prepared mixture should be poured into the fuel tank, the lid of which is indicated as an image of a gas station. This is very important, since chainsaws have two similar tanks. The second tank is intended for filling oil, which is consumed to lubricate the bar and chain during the operation of the tool.

It is important to know! After refueling the gas tank, do not rush to start the tool. Be sure to also add oil to the oil tank to prevent overheating of the chain, which could result in damage to the chain.

As an oil for lubricating the chain, it is recommended to use special branded or engine oil for a car, but in no case should it be used. If you see how your neighbor fills mining in a chainsaw, then you should not repeat his mistakes, as this significantly reduces the life of not only the chain, but also the tool itself.

It is always necessary to control the level of oil and the fuel mixture in the tanks, but it is recommended that refueling be carried out according to the following scheme:

• The fuel-oil mixture is filled into the tank until it is full.
• At the same time, chain oil is also filled to the full.
• The consumption of oil and fuel mixture is approximately the same, so both tanks are recommended to be filled at the same time.

How to start a chainsaw: launch features

Once the tool is ready to run, you can proceed. The process of starting a chainsaw is as follows:

Having launched a chainsaw, you can begin to work on sawing wood.

It is important to know! The material describes the process of launching the tool, after which you can start working with it. Do not forget that if you bought a new chainsaw, then it should initially be run in.

How to operate a chainsaw

Working with a chainsaw is one of the most dangerous, so it is very important to control the position of the tire as far away from you as possible. Each subsequent action must be deliberate, otherwise the consequences in the form of serious injuries cannot be avoided. If you have to work with a chainsaw, then you should know the following features:

1. It is required to work only in appropriate overalls: a protective helmet, headphones, a suit, gloves and shoes. This will increase the security of the master several times.
2. You need to hold the tool exclusively with two hands, and take the appropriate position with your feet in the form of a reliable stop. Working while standing in an uncomfortable position is strictly prohibited.
3. Lean the tool against the wood with a moving chain at medium speed.
4. Sawing with the tip of the tire should be done with extreme caution, as the likelihood of kickback is quite high.
5. When working, remove from the sawing area all unnecessary objects that can cause imbalance.
6. If you are tired, then you need to muffle the instrument, allowing not only yourself, but also him to rest.
7. When working, the legs should be widely separated to the sides, and the back should be straight.
8. You can cut wood not only with the bottom of the tire, but also with the top, only it is important to know that the chain will lead in the appropriate direction.
9. When moving with a chainsaw to another place, the tool should be turned off or put on the handbrake.

The above features are also suitable for working with an electric saw. Work is best done in tandem with a partner who can not only insure, but also replace you when you get tired. After all, working with such a tool is not easy, because in addition to physical strength, quick wit is also required. Observing the above rules for working with a chainsaw, all types of manipulations performed will have a successful conclusion.

Chainsaw Care

Another important condition for working with the tool is to ensure proper care for it. After completing the work, you should not leave the chainsaw at the workplace until the next time. It is necessary to clean it of sawdust and debris, periodically check the chain tension, as well as the fullness of the gas tank and oil tank. It is also important to watch for air filter clogging.

It is not recommended to store a chainsaw with fuel for a long time, so it is better to drain it. It is necessary to replace the chain, bar and drive sprocket in a timely manner, as these are elements that wear out quickly.

In conclusion, it is important to note that over time, the chain tends to stretch, which results in the fact that it cannot be tensioned. If you observe this property, then it is not recommended to continue to operate the tool until the cutting tool breaks at all or jumps off the tire. If a person is not confident in his abilities, then it is better not to take on sawing trees of large diameter.

Almost every person living in a private house or having a summer cottage uses a chainsaw powered by a gasoline internal combustion engine from time to time. For beginners in this regard, the question often arises of how to properly start a chainsaw. It is worth noting here that professional, semi-professional and household tools start up in about the same way. How exactly to do this will be described in the material.

Features of launching the tool

To run the tool, you need several processes to happen at the same time:

• a fuel mixture must be supplied under the engine piston;
• it should shrink as much as possible;
• at this point, a spark must be applied to ignite and start.

Each of these processes occurs at the moment when you pull the starter handle. When using a new chainsaw, you need to remember to break in.

However, in reality, everything is not so simple. Fuel for starting the tool in hot and cold engine mode must differ in the quality of the air mixture. So, a hot engine can start with a normal air level, which will ensure its stable operation and will keep idle speed normally. However, a similar amount of air will be enough to start a cold engine. Before starting the chainsaw, the starter will need to be pulled about 10 times and possibly more.

To reduce the amount of air and increase the fuel supply in the chainsaw carburetor, a special damper is installed that is responsible for adjusting the amount of air when starting the engine. It will be faster to start the engine with a saw, so the duration of the starter and the saw as a whole will be increased.

It is very dangerous to start the saw at the refueling point.

Run according to instructions

Different models of chainsaws have their own launch features and their own mechanisms. We will consider the device startup algorithm using the popular Stihl M. S. 180 chainsaw model as an example.

Before starting the startup process, it should be noted that the instructions for some chainsaw models say that before starting the tool, the emergency stop brake must be engaged for added security. But with a fixed brake, starting will be more difficult..

Accordingly, it will be better to unfix it.

If everything is done correctly, then nothing will be difficult. If you are worried that without fixing the chainsaw will cause harm at the time of launch, then it is better not to risk it at all and not get to work. So, the algorithm for launching the Calm tool is as follows:

• Before starting the instrument, the flap adjustment lever must be moved to the lower position. Remember that he moves the saw to the bottom only if the gas button is pressed. Press the gas button and move the lever down. So you close the carburetor damper and fix the gas in the pressed position;
• Next, vigorously pull the starter handle until you hear the characteristic sound of trying to start the tool. He should shut down right away. Then the damper position adjustment lever is moved one step up;
• In this position, pull the starter handle again until the saw starts. And if it starts, then due to the fact that the gas handle is fixed pressed, the work will take place at high speeds;
• Then press and release the gas button once so that the throttle adjustment lever automatically assumes the working position and the speed decreases;
• If it is necessary to bring a heated chainsaw into operation, you need to put the lever in the working position, and then start it;
• To stop the engine of the machine, the choke control lever must be moved to the up position.

Tool holding

To properly start the chainsaw, you should hold it in the right way at the time of starting. The position of the saw is very important here. Holding at the moment of launch can be carried out in two ways.

In the first case, the saw is placed on a flat surface, while holding the left hand straight and holding the tool by the upper handle, put the right foot on the protection for the second hand, and press the tool to the ground. In a similar position, it will be convenient to launch the tool, since your right hand is free, and the tool is fixed quite securely.

Regardless of the position in which you plan to start the saw, be sure to turn on the saw chain brake.

In the second option, you need to take a standing position and hold the upper handle of the tool with your left hand, and hold the back handle between your legs. Thanks to this position, you can easily wind a low-power tool, and it will be securely fixed, thereby protecting yourself from an accident.

Start without starter

Often, many home craftsmen are interested in whether it is possible to power a chainsaw without the help of a starter. The answer is very simple: it cannot be done in principle.

None of the manufacturers provided other alternative ways to start. Therefore, even if you remove the starter and try to start the car in some other way, it will still not work, because violations will occur in the cooling system. In this system, there is a volute to transfer the flow of cold air from the flywheel impeller towards the cylinder. If it is not, then the engine will overheat and eventually jam.

Reasons why the chainsaw does not start

The tool must be launched strictly according to the instructions. But if you have completed all of the above points, and the saw still does not start, this means that something is wrong with it. There are several reasons why it may not start:

• there is no spark;
• fuel is not supplied;
• clogged air filter.

So, what needs to be done to reveal the true reason why the tool does not work?

First, it must be said if the tool does not start, the screws on the carburetor should never be turned. And if you are not a professional in this field, then even do not try to tune anything with your own hands or try to start the instrument.

The steps listed below, which are necessary for the tool to start working, must be performed in a strictly specified sequence. You need to start the next step only when the previous one did not work. The actions are:

The above material discussed how to start a chainsaw correctly using the example of one of the Calm models, as well as how to behave if the tool cannot start. If you are new to this business or have encountered a problem, then this information may be useful to you in the future.

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. The useful tips given here for chainsaw operation are based on the recommendations of the 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.
