Chainsaw instruction manual. Model range of Stihl chainsaws

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.

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.

Husqvarna 5200- Chinese fake, was in operation for more than 5 years. Over the years there have been no complaints about the work of the saw, but the time has come, and problems have appeared. The idle speed increased by itself, the chain did not stop, the idle screw did not help. I didn’t pay much attention, because it was possible to work. But gradually the problem intensified, the idle speed increased to such an extent that it was possible to cut without even pressing the gas lever. At some point, the saw stalled and completely stopped starting. I was not particularly upset, since there was another saw on the farm, manufactured by another company. And the Chinese Husqvarna was quietly gathering dust somewhere in the corner, until it once again caught my eye. And once again I thought: is it possible to repair it? Of course, there was not even a thought about the service center, it was very far away, and indeed ... the game is not worth the candle. Decided to dig in and figure it out myself. Searched the Internet, asked around on the forums. The answer is almost the same everywhere: carburetor or crankshaft oil seals. I bought a carburetor and changed it. The result is null. Well, as for the oil seals, the matter is more complicated, but still I decided to look. Began to disassemble gradually. When I removed the cylinder, I found a surprise. The gasket between the crankcase and cylinder was damaged. In fact, it was almost non-existent. Chainsaw instruction manual From the gasket, only small pieces remained in the corners. Unfortunately, there was nothing at hand to make a new gasket. I cut it out of thick cardboard, smeared it, installed it. Collected the saw, pulled the starter. The saw started up. A small adjustment of the carburetor, final assembly - and the saw worked for almost a year. Then the same symptoms reappeared. I immediately thought that everything was repeating itself. Most likely, the paper gasket did not withstand the function assigned to it. Actually, that's how it turned out. An example workflow. We unscrew five bolts, remove the top plastic cover. Remove the air filter, unscrew the candle. You can immediately remove the tubular handle, as it will interfere later when installing the cylinder. Remove the muffler by unscrewing two bolts and two nuts (1,2,3,4). We unscrew the two bolts (1.2) that secure the carburetor to the vertical rack. We tighten two rubber tubes, remove the carburetor. We unscrew the two bolts of the vertical carburetor rack and four bolts of the cylinder. We take out the rubber tube from the hole in the vertical rack. Remove the cylinder together with the vertical stand. The photo below is the old gasket. We take a sheet of paronite 1 mm thick and approximately 80x80 mm in size. Mark with a compass and cut a hole dia. 50mm. With an awl, we mark the centers of future holes for fastening, then cut them out with a scalpel right on the cylinder. To prevent the gasket from moving, bolts can be temporarily inserted into the holes already cut. Cut off the outer edge of the gasket. We collect everything in the reverse order.

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 that 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.

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.

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.

The owner of a private house, cottage or cottage sometimes needs to cut wood. In this case, you need to purchase special equipment. A chainsaw is in some cases an indispensable tool. To work quickly and safely, before using the equipment, you must read the detailed instructions for this process.

Every master should know. If you do not follow the rules specified by the manufacturer of such equipment, there is a high risk of accidents. Therefore, before operation, it is imperative to consider in detail all the subtleties of the operation of the equipment.

Equipment Features

Starting to study the issue How to use a Husqvarna chainsaw"Calm", "Friendship" or other varieties of similar equipment, you need to delve into the features of each instrument. All existing varieties are conditionally divided into three groups.

Household appliances belong to the first class. They are used for private use when performing a small amount of work. Such chainsaws have low power. But for a home master, such functionality will be more than enough. It is relatively inexpensive and lightweight equipment.

Semi-professional chainsaws allow you to cut down trees. With their help, they also carry out construction or repair work. The operating time of the tool does not exceed 8 hours a day.

Professional chainsaws are able to work up to 16 hours a day. The time of their continuous operation reaches 9 hours. This is expensive, heavy equipment. Only specialized companies and enterprises can afford to buy it.

Features of domestic chainsaws

The domestic tool has certain design features. To operate them correctly, you need to study The most common tools in this category are "Friendship", "Friendship-Altai" and "Ural". They have been on the market for a long time.

To understand how to use the Druzhba chainsaw and other brands, you need to consider their device. The equipment has an engine and a clutch, there is also a gearbox. Be sure to come with a sawing machine. To be able to control the operation of the starter, special design elements are provided.

The power system has a gas tank, carburetor and tap. By gravity, fuel enters the carburetor through the gas pipeline with the tap open. The removable starter starts the engine. All these systems must work properly in order to ensure the normal functioning of the equipment.

Features of foreign chainsaws

The most popular today are the Husqvarna and Shtil chainsaws. Their device is similar to domestic varieties of instruments. However, their device has several features. They should be studied before How to use a Stihl chainsaw or Husqvarna.

The presented equipment of foreign companies is characterized by relatively low weight. This makes work much more comfortable. Husqvarna has a gas suction function. This is very convenient if a situation has occurred when the gas has run out and the engine has stalled. At the next refueling, this function will allow the saw to start immediately.

"Calm" has a quick-release cover, which is very convenient in case of filling the candle with gasoline. Bolt-on devices cause certain difficulties. In this case, fastening must be done with only one screw. Foreign equipment has a large set of additional functions. However, the operating rules for all types of chainsaws are common.

Tool preparation

Considering how to use a chainsaw, you should start with a detailed study of the manufacturer's instructions. Here are all the details of the operation of the equipment.

Before starting work, the tool must be checked. Start with To do this, it is pulled by the upper link. Ideally, the shank comes out of the groove by a few millimeters. In this case, the lower section of the chain should not sag. Otherwise, the chain must be tightened. After that, it should stretch easily. Strong tension is also unacceptable.

The handle of the inertial brake must not come into contact with the main handle. Otherwise, when the saw is operated, the clutch will shift. An elementary initial check can significantly reduce the likelihood of equipment failure.

Refueling

Considering how to use a chainsaw Stihl, Jonsered, Husqvarna, Partner and other models, attention should be paid to the refueling process. Almost all of the presented types of devices have a two-stroke engine. It is not capable of running on a pure gasoline mixture. Therefore, the fuel is prepared from certain components.

To prepare fuel, you will need to take 20 g of engine oil for 1 liter of gasoline. Gasoline should be A92 for domestic instruments and A95 for expensive foreign models. Recommendations for selection are indicated in the manufacturer's instructions.

Engine oil must be specifically designed for chainsaws. Conventional automotive varieties in this case are not suitable. In a plastic container, mix oil with gasoline. The resulting mixture must be poured into the tank. Its hole is marked with a gas station icon. The mouth of the oil container is marked with a drop.

Chain lubrication

In order for the equipment to work for a long time, and its functioning to be of high quality, it is necessary to periodically add lubricant to the chain. Most often, manufacturers recommend using only branded oils. If the user decides to use a different tool, you can replace the special lubricant with automotive varieties. The viscosity of such a product must correspond to the level indicated by the manufacturer.

After choosing the right lubricant, you need to understand how to use a measuring container for a chainsaw. The marks are located near the neck. When working with the presented equipment, it is necessary to periodically check the oil level inside the saw.

It is recommended to lubricate the tire bearing once a month. It is located on its outer end part. If the design provides for a special hole, oil is poured there. Just a few drops are enough. Refueling with oil and fuel should only be done on a hard, level surface.

Safety

studying, how to use a chainsaw, the safety regulations must be considered. This will help prevent accidents while using the tool. All rules are specified in the instruction manual.

During operation, the saw should be held firmly with both hands. The thumb of the left hand should be placed under the front handle. It is necessary to stand on wide-spaced legs to the side of the saw. Do not stand directly behind the instrument. The back is not bent. It must be even.

If the master needs to move to another position, the equipment must be put on the brake. If this rule is neglected, there is a high probability of serious injury. It is necessary to start sawing with the end of the tire.

It is extremely important to wear overalls and protective equipment. These include goggles, special pants and a lined jacket, as well as tight shoes with steel inserts.

launch

The procedure for starting a chainsaw must be carried out carefully and in a certain sequence. The tool must be placed on a flat, solid surface. The chain must not come into contact with any objects.

Next, consider How to use the chain brake on a chainsaw. To activate it, turn the handle away from you. This will prevent the chain from immediately starting to spin on startup. If your particular saw model has a decompression valve, it should also be activated.

The choke lever must be removed. The toe of the right foot should be placed in the handle behind the saw, and the front foot should be held with the left hand. Pull the starter cord quickly several times. The engine will make a characteristic sound similar to sneezing. This means that the tool has been activated.

After that, the air damper must be returned to its original position. After that, you can start the saw. To do this, you need to continue to pull out the starter cord. The engine needs to warm up. At this time, do not remove the brake (fuse).

felling process

Considering how to use a chainsaw, it is necessary to pay attention to the cutting process. There should be no strangers in the work area. When you need to determine the correct direction. The slope of the terrain and the trunk itself, the strength and direction of the wind should be taken into account. This will make it easier to determine where the tree will fall.

The space around must be cleared of shrubs and overgrowth. There should be no foreign objects under your feet. There should be no foreign objects or people within a radius of two lengths.

The guide notch is made low. This makes it easier to drop the barrel. When the tree is felled, you need to stand on the left. The barrel must be fixed so that it does not move during operation. Branches are cut from below. The cut is made with the top of the saw.

Tool maintenance

Having studied the methodology how to use a chainsaw, attention must be paid to proper maintenance. After completion of work, the instrument should be assessed for integrity. Lubricate the chain if necessary.

Particular attention must be paid to the health of the fuse, control levers and catcher. The mechanism must not be damaged. Fasteners must be tightly tightened.

After use, the instrument should be thoroughly cleaned. To do this, open the cover and remove dirt from the brake band. You should also clean the tire. The air filter must be washed from small particles of wood. The cooling fins are wiped, the ventilation holes are cleaned. You also need to inspect the flywheel blades.

Chain sharpening

With intensive work, the tool may require maintenance of the cutting blade even in the process of cutting one trunk. Therefore, it should be considered how to use the machine The procedure can also be performed with files, but in this case the process will be lengthy and less effective.

There are many types of such equipment on the market. Following the manufacturer's instructions, you can set all the necessary sharpening parameters. In this case, the work will be done quickly and efficiently.

Having considered the features of the operation of chainsaws, carefully studying the manufacturer's instructions, you can ensure high safety for the master, as well as a long tool life.

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. Training.
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). It will become a reliable protection against 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. 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.
