How to start a chainsaw: features of proper operation. Chainsaw operation: first start, safety precautions, video instruction Starting a chainsaw description

We will devote the second part to what needs to be done if you did everything correctly according to the instructions, but the chainsaw still does not start. Also, this part will be useful for those who have a poor start-up of a chainsaw.

1. We start the chainsaw according to the instructions

It should be noted that different chainsaws can start in different ways. We will take a Stihl MS chainsaw as an example and show you how to start it. If you have a different brand of chainsaw, then try to start it in the same way, since most likely the mechanism of your saw is the same or slightly different.
Before starting the description of the starting process, we would like to draw your attention to the point in the instructions that says that before starting the chainsaw, you need to turn on the emergency stop brake. This is suggested for security reasons. However, this greatly complicates the task of starting the chainsaw, so we will unlock it. If you do everything with care, then the chainsaw will not harm you during the start. If there are fears that without fixing the brake of the chainsaw, during the start, it can harm you, then it is better not to take up this tool at all.

Let's get started. The first thing to do before starting the chainsaw is to move the choke adjustment lever to the lower position (Fig. 1). Please note that this lever moves down on the chainsaw all the way down, only if the gas button is pressed. Therefore, we hold down the gas button and move the lever down. Thus, we close the choke in the carburetor and fix the gas in the pressed position at the chainsaw.

After you have done this in order to start the chainsaw, we begin to pull the starter handle with an energetic movement, when we hear that the chainsaw tried to start and immediately stalled, we move the throttle position adjustment lever at the chainsaw one step up (Fig. 2).

In this position, pull the starter handle again until the chainsaw starts. But due to the fact that the throttle stick was fixed in the pressed position, the started chainsaw will immediately work at high speeds.
Then, once press and release the gas button on the chainsaw - the choke adjustment lever is automatically set to the operating position (Fig. 3), and the speed of the chainsaw is reduced. Now you can get to work.

If you need to start a heated chainsaw, then you just need to put the lever in the position, as in fig. 3 and can be run.
To stop the chainsaw engine, lift the choke adjustment lever to the upper position (Fig. 4).

2. Why won't the chainsaw start?

If you did everything according to the instructions, but the chainsaw does not start, then something is wrong with it. This may be due to several of the most common reasons: there is no spark; no fuel is supplied; the air filter is clogged. Below we offer a procedure to help identify the reason why the chainsaw will not start.

3. Procedure if your chainsaw does not start

It is very important if your chainsaw does not start - do not turn any screws on the carburetor unless you are a specialist. You still will not be able to set up something on your own and you will not be able to start the chainsaw.
Follow the next steps required to start the chainsaw in the order shown, starting with the next number only if the previous one did not help.
1) Try to start by simply leaving the chainsaw alone for 5-10 minutes. Perhaps during the launch, a candle flooded in her - it happens. Then try starting again according to the instructions.
2) Remove the housing cover on the chainsaw, take out the air filter and try to start without it. If the filter is dirty, wash it in soapy water and dry it or replace it with a new one.
3) Unscrew the spark plug from the chainsaw. Check for a spark. If there is no spark, then try putting in a new candle. If the spark still does not appear, then this means that the ignition unit is damaged and the saw needs to be carried for repair. True, visual observation of a spark does not mean that the ignition unit is working properly. If there is a spark, and the chainsaw did not work, do the following steps on the list.
4) If there is a spark, but the plug is wet, then turn the chainsaw over to drain excess gas from the cylinder if it has accumulated there. Pull the starter 10-15 times without a spark plug to ventilate the combustion chamber. Ignite the candle and screw it back, or better, change it to a new one, if available. Try starting again according to the instructions.
5) If the candle is dry, draw one or two cubes of gasoline mixture into the syringe and pour it into the cylinder. Try to start the chainsaw - perhaps a small speck has got into the carburetor, which prevents the fuel from entering the combustion chamber. It is quite possible that this speck will be pulled out by the stream formed after starting the chainsaw by adding fuel directly to the cylinder.
6) Unscrew the muffler and remove it, being careful not to spoil the gasket between the muffler and the engine. Try starting without muffler and air filter. With the muffler removed from the chainsaw, you can inspect the piston from the inside. If there are burrs or scuffs on the walls of the cylinder or the piston, or the ring on the piston is jammed with burrs, then you will have to be very upset, as this means that the piston is damaged or worn out. This usually happens when oil is not added to the fuel mixture. With such a malfunction, you will have to contact the service, and perhaps think about buying a new chainsaw, since replacing a piston one is a rather expensive operation.
Thus, we have discussed in this article how to start the chainsaw "according to the instructions", as well as what to do if the chainsaw does not start. We hope you find these tips helpful.

All chainsaws from the Shtil manufacturer have two-stroke engines. They are carried out according to a similar algorithm. However, on sale you can find models on which there is optional equipment, it can be used to start the saw without applying special efforts... For this reason, the starting method may differ.

Algorithm for the establishment of the saw "Calm 180"

If you are faced with the question of how to start the "Calm" chainsaw, then this process can be considered using the model 180 as an example. In order to carry out work on a cold one, you must turn on the ignition and set the engine control lever to the lower position. In this case, the carburetor flap will block the air from the filter, and the throttle will be open, so the fuel mixture will be enriched.

The starter handle must be pulled several times until the first flash occurs. This will indicate that the mixture has entered the cylinder and the equipment is ready for institution. Before starting the "Calm" chainsaw, you must set the control lever one position up. This will open the choke, while the throttle remains in the same position.

The starter must be pulled and started. The tool will run at increased speed and the throttle valve will be open. To set the latter in idling mode, you must use the gas trigger and release it. In this case, the tool should start working normally. On the described model of the chainsaw there are no additional devices that would make it easier to start.

This device, in comparison with the previous one, has some differences in the trigger mechanism. However, there will be no changes in the startup algorithm. The equipment described has a system that uses a spring in the saw starter to reduce the resistance of the motor.

We start the saw brand MS 211 C-BE

If you, too, are among those consumers who have pondered the question of how to start a Stihl chainsaw, then as an example we can consider another model that was mentioned above. In it, the feed system is equipped with a hand pump, which makes it easier to start the saw when it is cold.

The instruction contains an additional paragraph, which indicates that before starting with the pump, it is necessary to pump fuel into the carburetor. Next, you should proceed according to the principle that was described for the 180 model.

Setting up the saw after winter

If you are faced with the question of how to start the "Calm" chainsaw after winter, then you should familiarize yourself with the recommendations. From consumer feedback, it can be understood that after a long period of inactivity, some users cannot start the equipment. For a successful start, you need to take care of the saw in advance.

Before storing it, you should drain the fuel, and then start the engine and burn off the fuel that remains in the system. Preparation is necessary so that the membranes do not stick together during storage. This simple operation will allow you to start the saw after winter. If you still do not know how to properly start the Stihl 180 chainsaw, then you should know that it will be easier to do this if you add 2 ml of fuel mixture to the cylinder through the spark plug hole before starting. This can be done with a syringe.

Saw installation with decompression valve

Users sometimes ask how to launch when the instrument has a decompression valve. There is none on the 250 model. As soon as the first flash occurs, the valve will be in normal operation. The engine control lever will be set when the choke is open. Start-up will continue and the decompression valve must be pressed again. It does not make the start-up fast, but it simplifies the process and makes it comfortable, because during the start-up the operator will have to put less effort.

If you are not entirely sure that you know how to start a Stihl 180 chainsaw, then remember that equipment with a valve, regardless of whether it has a hot or cold engine, must be started using the valve. This will ease the effort to crank the engine. So you can extend the life of the starter and reduce the number of torn laces, because these chainsaws have a larger cylinder volume and compression.

Quite often, consumers before buying are wondering how to start a Stihl 250 chainsaw. This was discussed above. However, this information is not the only one that should be read before using the model. Among other features, it should be highlighted:

• single-lever control;
• the presence of a compensator;
• anti-vibration system;
• side chain tensioner.

By purchasing this model, you will be able to carry out its quick refueling. This feature is realized by the lid, which has a patented design. The operator, working with the equipment, will have reliable protection hands. Consumers especially highlight the notch bumper, as well as the chain, which guarantees high-quality and fast cutting of wood.

Conclusion

After purchasing the equipment described in the article, you should ask how to start the "Calm" chainsaw. This information will allow you to extend the life of your tool. After all, improper handling can cause rapid wear of some parts. It is especially important to know how to prepare the machine for extended downtime. This was discussed in more detail above. After reading this information, you can understand how to prepare the device for winter storage.

Sometimes, some consumers are told about the features of the launch. specifications... If this can help you too, then you should familiarize yourself with them. Some of them were presented above, but a complete list of them is presented in the instructions, which are necessarily supplied with the equipment.

The question of how to start a chainsaw can be divided into two parts:

1. Factory according to instructions
2. What to do if you can't start

The information from the first part will be useful to those who have lost the instructions, or those who have little information about the instructions.

The second part will tell you what to do if you did everything correctly according to the instructions, but the chainsaw still won't start. It will also be useful for those who have a poorly started chainsaw.

1.We start the chainsaw according to the instructions

For different chainsaws, starting up can be done in different ways. Let's look at two of the most popular mechanisms that are used to start a chainsaw that exist today. For example, take chainsaw Stihl MS 180 and Echo CS-352ES. If you have a different brand of chainsaw, then just try to start by analogy, since most likely you have the same or similar mechanism.

Before starting the description of the starting process, I would like to note that for some chainsaws, the instructions say that before starting the chainsaw, you need to turn on the emergency stop brake. They say it's safer. However, with a fixed brake, starting the chainsaw is more difficult, so it is better to unlock it. If you do everything according to your mind, then the chainsaw will not do anything to you during start-up. If you are afraid that without locking the brake the chainsaw, when you try to start it, can harm you, then it is better not to take this tool at all.

So let's start with the Stihl MS 180.

Now let's take a look at the second second mechanism that allows you to start the chainsaw.

2.Why won't the chainsaw start?

If you did everything according to the instructions, and the chainsaw does not start, then something is wrong with it. This may be due to several of the most common reasons: there is no spark; no fuel is supplied; the air filter is clogged. So, below we propose a procedure that will help identify the reason why the chainsaw does not start.

Procedure if your chainsaw does not start

The first thing I would like to note, if your chainsaw does not start, do not turn any screws on the carburetor. If you are not an expert, you will still not be able to set up something on your own and you will not be able to start the chainsaw.

Follow the next steps required to start the chainsaw in the order shown, starting with the next number only if the previous one did not help.

1. For a start, try just leaving the chainsaw alone for 5-10 minutes. Perhaps during the start-up, a candle flooded in her - it happens. Then try starting again according to the instructions.
2. Remove the housing cover on the chainsaw, remove the air filter and try to start without it. If the filter is dirty, wash it in soapy water and dry it or replace it with a new one.
3. Unscrew the spark plug from the chainsaw. Check for a spark. If there is no spark, then try putting in a new candle. If the spark still does not appear, then this means that the ignition unit is damaged and the saw needs to be carried for repair. True, visual observation of a spark does not mean that the ignition unit is working properly. If there is a spark, and the chainsaw did not work, do the following steps on the list.
4. If there is a spark, but the plug is wet, then turn the chainsaw over to drain excess gas from the cylinder if it has accumulated there. Pull the starter 10-15 times without a spark plug to ventilate the combustion chamber. Ignite the candle and screw it back, or better, change it to a new one, if available. Try starting again according to the instructions.
5. If the candle is dry, then draw one or two cubes of gasoline mixture into the syringe and pour it into the cylinder. Try to start the chainsaw - perhaps a small speck has got into the carburetor, which prevents the fuel from entering the combustion chamber. It is quite possible that this speck will be pulled out by the stream formed after starting the chainsaw by adding fuel directly to the cylinder.
6. Unscrew the muffler and remove it, being careful not to spoil the gasket between the muffler and the engine. Try to start without muffler and air filter.

If there are burrs or scuffs on the walls of the cylinder or the piston, or the ring on the piston is jammed with burrs, then you will have to be very upset, as this means that the piston is damaged or worn out. This usually happens when oil is not added to the fuel mixture. With such a malfunction, you will have to contact the service, and perhaps think about buying a new chainsaw, since replacing a piston one is a rather expensive operation.

Thus, we have analyzed in this article how to start a chainsaw "according to the instructions", as well as what to do if the chainsaw will not start. We hope you find these tips helpful.

With the development of gas powered tools, a chain saw with a gasoline internal combustion engine (ICE) appeared in almost everyone who lives in rural areas or has a summer cottage. Household models, semi-professional-grade tools and professional units start up about the same. But not everyone knows how to start a chainsaw correctly. We will try to understand this issue and figure out how to start a chainsaw.

In order to start the chainsaw, several processes must occur at the same time. This is the supply of the fuel mixture under the engine piston, its maximum compression and the supply at this moment of the spark for ignition and start.

All these processes occur at the moment when we pull the starter handle. If you have a new chainsaw, then don't forget that it should.

But not everything is as simple as it seems, the fuel for starting in cold and hot engine modes must differ in the quality of the air mixture. For example, a hot internal combustion engine can start with a normal air level, at which it works stably and keeps idling speed confidently. The same amount of air will be too much to start a cold engine, and before starting the chainsaw, you will have to pull the starter 10 times, or maybe more. How can this problem be solved?

To reduce the amount of air and increase the supply of fuel, the manufacturers of chainsaws installed a special damper in the carburetor, which is responsible precisely for the process of adjusting the amount of air at the time of starting the internal combustion engine.

It turns out to start the saw engine several times faster, which increases the operating time of the starter and the entire saw as a whole.

Starting the saw where you refueled is dangerous.

So how do you start the saw correctly? The startup algorithm is as follows:

• Close the air damper completely. To do this, in all chainsaws, a special lever is installed, pulling which closes.
• Using a primer, pump fuel into the carburetor. This is necessary so that the internal combustion engine does not require several working cycles to fill the carburetor.
• Perform several movements of the starter until the first ignition in the cylinder. It is called the first outbreak. We will dwell on this point in more detail because of its extreme importance for a correct launch. It is at the time of the initial ignition that optimal conditions for later launch. Under the influence of the temperature from the first flash, the fuel in the cylinder evaporates, forming gas vapors, and as everyone knows, it is they who participate in the operation of the internal combustion engine. Therefore, the next stage should complete the process, and finally start the chainsaw engine.
• Open choke halfway and move with starter. After these actions, the chainsaw should start and start working at high speeds; to normalize them, you must press the control lever for the number of revolutions to the maximum and immediately lower it. After these actions, a properly adjusted engine will go into idle mode and reduce rpm.

What happens if you don't open the air damper after the first flash? The answer is simple, the carburetor will not reduce the flow of fuel to the cylinder, and it will flood the spark plug electrode. After which, even a large number of movements with the starter, will not allow the chainsaw to start.

Purge after algorithm violation

If the first time, do not worry, this happens, most likely the problem lies in the excess fuel in the cylinder. It is necessary to carry out preparatory operations, namely, remove the fuel from the cylinder, and try to start again.

Eliminate the problem by unscrewing the spark plug and blowing out the cylinder. To do this, it will be necessary to turn the tool with the candle hole down, turn off the ignition button and make several movements with the starter in this position. Compression will cause the engine to squeeze out excess fuel, after which you can try to start the saw with the throttle fully open.

How to hold a chainsaw

To carry out the correct start of the chainsaw, important point is how the saw is located at this moment, more precisely, how the operator holds it. There are two options for correctly holding the saw at the moment of starting.

The first option: the saw is installed on a flat surface, left hand The operator is straight and holds the saw by the upper handle, with the right foot on the right-hand guard and pressing the saw to the ground.

In this position, it is most convenient for the operator to launch the tool, since the right hand is free and the tool is securely fixed.

Before starting the saw, regardless of the position in which it will be carried out, the saw chain brake must be applied.

Option two: The operator is standing, the left hand is holding the upper handle of the saw, while the rear handle is clamped between the legs by the operator.

This position allows you to easily start a low-power saw, and at the same time securely fix it, preventing yourself from accidents.

Before starting the chainsaw, make sure that there are no people or animals in the immediate vicinity.

You can watch a video on how to start a chainsaw and visually study the steps at start-up below. In the video, a specialist from the Shtil company talks about how to properly operate the tool and launch it using the example of the Shtil MS 211 chainsaw The video is very informative and contains reliable information from the manufacturer.

The answer to the popular question about starting a chainsaw

On the Internet, very often you can find questions about how you can start a chainsaw without the help of a starter. The answer is simple - it is impossible in principle to start a chainsaw without a starter. Manufacturers do not provide for any alternative starting methods, because even if you remove it and start the saw in some way, it will be impossible for it to work due to irregularities in the cooling system. In it, a volute is installed, which transfers the flow of cold air from the flywheel impeller to the cylinder.

If removed, the engine will overheat and most likely jam.

A method for starting a hot engine and an engine equipped with a decompression system.

A hot engine does not need to enrich the fuel mixture with air, so you can start the saw without closing the air damper. The ignition is simply turned on and a movement is made by the starter, after which a serviceable chainsaw should start.

Large displacement engines have quite severe compression, which makes the cranking process extremely difficult. To reduce the effort required to start a saw with a large volume and power, manufacturers use special decompression valves, when pressed, the compression is noticeably reduced and the engine turns more easily.

Valves can have different kind, therefore, read the instructions for the tool in advance.

Thus, before any kind of starting, whether hot or cold, it is necessary to press this valve, designed to reduce the resistance, and thereby increase the life of the starting device.

In conclusion of the article, you can summarize the key points of starting a chainsaw. First, you need to start with maximum safety. Second, any deviations from the startup algorithm are not allowed. And finally, you can't start a chainsaw without a starter! Consider the information from the article and use your tool correctly.

In the midst of harvesting firewood, it would be very annoying to be left with an inoperative tool, so it is important to know how to start the chainsaw, how to do it correctly and what to do if the saw does not start. Let's talk about this in more detail.

The chain saw is a rather complex device and therefore requires correct operation and competent maintenance for trouble-free operation.

To start the saw reliably, first of all, a working spark plug, a reliable fuel supply and a properly prepared fuel mixture for two-stroke engines are required. By the way, it should be noted that after a long downtime of the saw, it can be difficult to start it the first time, and here you are very lucky if the saw is equipped with a manual fuel pump, otherwise you may need to tinker a little.

Let's consider the general points. Although all chainsaws are similar to each other, there are still differences when starting. Therefore, in any case, read the instructions first. For example, on some Husqvarna petrol saws, the manual requires the chain to be locked with the emergency brake before starting. In some chainsaws of other brands, the opposite is said to avoid difficult starting.

And so, you pulled the starter handle several times, but the saw did not show the slightest signs of life (if there were "seizures", then you can wait a couple of minutes in order to allow a fuel cloud to form inside the cylinder and try to start the chainsaw again and the chances of success in this case is not bad), then do not force her, but first, do this:

What to do if the chainsaw won't start

Remove the spark plug and inspect it. It should be light brown and free of black patches. In addition, it should not be completely dry. This may indicate that there is no fuel supply. If it is very wet, then this indicates that you have flooded it.

In this case, simply dry the candle for a while, and blow out the cylinder several times by pulling the starter handle. Screw the spark plug back in and try starting the chainsaw again.

Chainsaw won't start, no fuel supply

This is a fairly common problem for cheap gasoline saws that are not equipped with a hand pump. On one occasion, I was unable to start the saw after a long period of inactivity in the usual way. But don't be discouraged, it is pretty easy to overcome this problem.

To do this, remove the air filter cover, take out the filter element and pour a few drops of gasoline directly into the carburetor with a small syringe. We wait half a minute until vapors form and pull the starter handle.

As a rule, in this case, the engine is started the first time. There is also a more radical and effective way. We unscrew the candle and pour a few drops of gasoline directly into the cylinder. We turn the candle back. The method is one hundred percent effective and the saw will start, but only if there is a spark on the candle.

How to check the spark on a chainsaw candle

Although much less often, it also happens that it is impossible to start a chainsaw due to the absence of a spark on the spark plug electrodes. How can you check for its presence? It's very simple. Again, we turn out the candle, put a high-voltage wire on it and ensure reliable contact of the spark plug body (that is, its skirt, where the thread is) with the cylinder block. After that, we pull the starter hand as when starting.

You should see the spark clearly. If there is a fuel supply, but there is no spark, then, most likely, the magneto is faulty or there is a broken wire somewhere in the system. In this case, check the integrity of the magneto and the continuity of the electrical circuit. After all these operations, the engine should start. If it failed, then write in the comments. Let's try to figure it out.
