How to breed gasoline for two-stroke chainsaw engines. The proportions of the mixture for refueling Stihl chainsaws. Preparing a fuel mixture for a chainsaw

Keeping the correct proportions of oil and gasoline for chainsaws avoids the vast majority of problems that arise with this tool. At the same time, it is necessary to select lubricants for both the saw set and the engine.

Ready solutions

The quality of the composition of the fuel mixture for a chainsaw depends on the uninterrupted operation of its operation, the consumption of components and engine wear.

In various outlets, you can always find ready-to-use mixtures. In them, the proportions of oil and gasoline for chainsaws are already observed. These include mixtures "Partner", "Calm", "Huskvarna".

However, the latter are not a cheaper analogue of the total purchase of oil and gasoline and self-manufacturing formulations.

Raw material requirements

The gasoline used in the preparation of the mixture must be at least brand A-92. Can also be used such as AI-92 or AI-95. Their shelf life should not exceed three months. This is due to the fact that after its expiration, the mass fraction of resins in gasoline increases, which causes the occurrence of polymerization reactions, which adversely affects the combustion chamber, in which a layer of soot is formed. Gasoline must be unleaded, as using the leaded variety will damage the engine.

The expiration date of the oil must also be observed. For the preparation of the mixture, you can use any high quality type "Partner", "Calm" or "Husqvarna". The choice of oil should be determined by the fact that it is impossible to use the latter for four-stroke engines and boats to prepare the desired composition.

In the manufacture of the mixture, it is imperative to read the instructions for forcing the engine. The last indicator shows the ratio of the volume and power of the motor and maximum speed).

Characteristics of the oil for the mixture

Chainsaws are equipped with this and the choice of oil must be appropriate. They can be of API-TA and API-TB grades, designed for them, which are air-cooled, and capable of operating under heavy loads.

Motor oils consist of a base and additives. The latter provide the best mixing of oil and gasoline. With their help, they prevent corrosive processes, as well as the formation of deposits, which reduces the smoke output and keeps the engine parts clean. You can read about the effect of additives on the packaging.

Oil types

Mineral oil is suitable for use in the warm season. This is due to the fact that it has a high viscosity. These oils can be purchased from 113 rubles/l (TNK 2T).

Synthetic oil has a high fluidity, which can also be used in winter conditions at low temperatures, that is, throughout the year. Mainly used for industrial chainsaws. This type is thermally stable and chemically stable. Their cost starts from 135 rubles / 0.2 liters ("Zubr-Expert").

With not very heavy loads on the tool, semi-synthetic oils can be used for year-round use. They include mineral types as a base component, to which synthetic ingredients are added. The cost of these oils ranges from 185 rubles / 0.946 liters (Resoil Ultra 2T).

Manufacturers paint oils in different colors so that you can control how to dilute gasoline for a chainsaw.

The capacity of the container must be selected based on the use of the tool. With a rare action of a chainsaw, 0.8-1 l of volume per season is sufficient. In the case of daily many hours of use, you need to focus on 5-liter canisters.

chain oil

The saw set is not lubricated with motor oils. For this purpose, special chainsaw fuel is used, which is characterized by high adhesion to the surface. Chain oil reduces friction and wear on parts that come into contact with each other.

Modern brands of chainsaws have a tank on the body that contains chain oil, with which the saw set is automatically lubricated.

During the operation of the tool during the cold season, semi-synthetic or synthetic oils are selected, during the warm season - mineral.

On some brands of oil, you can see the CEC marking, which indicates that they are made from plant-based and do not harm environment.

Main question

It consists in observing the proportions of oil and gasoline for a chainsaw. An extra first ingredient will cause carbon deposits to form on the candles and pistons. Excessive gasoline contributes to the fact that seizure will appear on the pistons, which will cause a quick failure of the engine. The exact proportions are indicated by the manufacturers themselves.

Husqvarna and Stihl recommend taking 4 liters of gasoline per 100 ml of oil. This is typical for tools with motor power up to 1.5 kW. With more power, the proportion should be 1/50. On average, when answering the question “How to dilute gasoline for a chainsaw?” it is recommended to proceed from the following proportions: 20-50 ml of oil per 1 liter of gasoline.

As you can see, different manufacturers have different approaches to observing the proportions of oil and gasoline. Therefore, it is necessary to strictly adhere to the instructions that go to the specific brands of the instruments in question.

Mixing must be carried out in special canisters, on which dimensional divisions are applied and there are two holes: one for oil, the other for gasoline. Components are poured there, the container is tilted and mixed with the lids closed. Water droplets or solid particles must not get into the prepared mixture.

However, these containers have a minimum mark of 1 liter, therefore, with smaller volumes, you can make a measurement yourself. For this you can take plastic bottle with a capacity of 0.5-1 l. Pour 102 ml of water into them (up to 816 ml) using measuring utensils. After filling each portion, a mark is made, at the level of which numbers are written from 2 to 18 in increments of 2. In order to measure the oil, we use a syringe without a needle with a volume of 10-20 ml. A step in 102 ml of water provides a proportion of 1/50. For other proportions, it must be changed accordingly.

The finished composition is stored for no more than 1 month. Even better, use it up within a few days. This is due to the fact that oxidation processes take place in it, which change it chemical composition. Perfect option mixture consumption - one day. If the engine breaks down due to overexposed fuel, this will be considered a non-warranty event. If, after the end of the season, the prepared mixture remains in the chainsaw, then you need to turn off the engine and remove its remnants.

Finally

We found out that it is imperative to maintain the proportions of oil and gasoline for chainsaws. It is best to follow the chainsaw and oil manufacturer's instructions. On average, the proportions of gasoline:oil should be 1/25-1/50. In this case, gasoline must be grades or AI-95. Oils can be mineral oils if they are planned for summer use, synthetic or semi-synthetic for all-weather use.

From the very beginning of their appearance, chainsaws have been gaining momentum in popularity and demand among consumers every year. different countries. And this is not at all surprising, since they are indispensable assistants in the field of agricultural activities, splitting trees, and are also successfully used in repair work. But, even despite their so-called popularity, they, like you and me, require attention and a peculiar approach.

This is especially true of the gasoline-oil mixture, which you pour directly into your "favorite". Since this the additive, namely its quality, directly affects the operation and productivity of the chainsaw.

In this article, we will consider all issues related to this necessary fluid. We will learn how to dilute gasoline with chainsaw oil, what proportion of oil and gasoline for chainsaws, and also what oil to add to gasoline for chainsaws. So let's get started.

Device aspects

Now we will “plunge” into the very core of this tool, so that you at least have a general idea of what your “assistant” consists of. In fact, this kind of tool can be responsibly attributed to the mechanisms of the classical direction, which work through the use of an internal combustion engine.

It can be said without exaggeration that what type of tool is the simplest of all other mechanisms, since the saw does not have a gearbox and is equipped with a conventional two-stroke engine that has one cylinder and runs on gasoline.

The main advantage of the chainsaw is that it is arranged quite simply, which contributes to increased reliability, as well as trouble-free operation in heavy and difficult conditions. Next, let's take a closer look at the design of the saw, so:

engine;
clutch;
ignition system;
carburetor (see carburetor adjustment);
fuel system;
air purification system;
starter;
chain (see how to sharpen a chain);
tire;
chain brake;
chain tension mechanism;
chain lubrication system (see chain oil).

In fact, the device was sorted out, but now the lubrication of the parts of the chainsaw remains an important issue. Many do not understand why it is needed at all? The answer is quite simple, like all mechanisms, a chainsaw, especially its individual parts, require special care including periodic lubrication.

This is necessary in order to your tool has served you for many years, since during operation, chainsaw parts produce a movement that must be smooth, smooth, so as not to damage nearby parts.

Just as everyone knows that the force of friction breaks the surface, so here, if you do not lubricate the chainsaw as necessary, the parts will simply wear out quickly and the tool will go out of tune. You need it? Don't think. Therefore, it is necessary to take care of your chainsaw so that it “has the strength” to serve you for many years.

Choosing the right quality oil

Naturally, after you purchased the device (see Russian-made chainsaw), you immediately had a question: what kind of oil should I dilute gasoline for a chainsaw? If you properly care for the equipment intended for work in the construction and garden areas, you can significantly increase the level of activity of the direct operation of the device itself and not encounter breakdowns of a different nature.

It is worth noting that the most important factors The immediate performance of the device is the use of the correct lubricant and fuel. Although the main problems for the owners of this technique are precisely with the choice of oil for their "favorites". At this point, you can find out how to select a lubricant:

First of all, what I would like to draw your attention to is that almost all chainsaws (see the rating of the best chainsaws) have a carbureted two-stroke engine. And also in their "arsenal" there are two direct tanks, namely: gasoline and oil. In order to choose oil for a chainsaw, you need to know certain criteria for this kind of choice.
First, do not forget that, for example, domestic chainsaw models require the use of only simple oils that are used directly for motorcycles, and tools that are made abroad need branded oils, since their requirements are largely overstated.
In fact, if you figure it out like this, then only you, as the owner of the equipment, can determine which oil to use.
Naturally, you can pour domestic oil into an imported chainsaw. But then you must be prepared for the fact that the power and productivity of your tool will be significantly reduced.
Mostly the owners of this kind of device are used engine oil, and if there is none, then they use gear oil. If you believe the experts, then in fact any oil can be used, even the one that you pour directly into a Zhiguli car, but there are certain kinds of features, namely: motor oil can be used for the device of the Khurstavna brand, but for the Stihl 180 chainsaw, exclusively transmission (see Stihl chainsaw oil).
Moreover, to choose the right oil, you need to know what color it should be. Since, for example, for chainsaws with a two-stroke engine, the oil should have red, blue or in green. Moreover, when you buy oil, you must necessarily take into account what kind of oil composition the manufacturer of your equipment recommends.
In addition, you can greatly facilitate the purchase for yourself, and purchase a special chainsaw oil of your brand, the price of which is not so high and which was produced by “your” manufacturer. And then you can be sure that your chainsaw will not give any malfunctions. Of course, you can buy cheap oil, but it's worth it to complain later that your chainsaw has served you too little time.

The ratio of gasoline and oil

And now let's deal with the question that worries the owners of this equipment: how much oil to add to gasoline for a chainsaw? First of all, it is worth noting that this kind of fuel mixture is made directly from two high-quality components.

The first, so-called additive, is gasoline unleaded, which has an octane number of at least 92. For example, AI-95 and AI-92 gasoline will serve this purpose perfectly. The second component is a specialized oil designed specifically for gardening equipment with a two-stroke engine.

Now we will figure out what ratio of oil and gasoline for a chainsaw is necessary, since this issue must be approached with all responsibility. So, in most cases, for one liter of gasoline directly, you need somewhere from twenty to fifty milliliters of oil.

And if you are concerned about the question of how much oil to pour into gasoline for a chainsaw, which has a direct power of about 1.5 kW, then in this case you will need 25 ml of oil per liter of gasoline.

For significantly powerful tools mostly applied about 30ml and sometimes even more. Of course you can find out necessary information directly on the oil container, but you will still find out the exact data from the oil dilution table with gasoline for your model chainsaw from its instructions.

How to mix gasoline with oil?

In order for the tool to serve you for more than one year and, moreover, so that you do not encounter any problems associated with its breakdown, you need to know how to properly prepare a mixture of gasoline and oil for a chainsaw. To date, Internet forums are simply exploding with questions regarding this topic. Therefore, in this paragraph, everyone can get useful and reliable information. So let's get started.

In order to directly prepare this kind of mixture, you need to buy AI-95 or AI-2 gasoline, however, we talked about this earlier.

We also clarified the fact that Use only unleaded gasoline, but did not specify the reason for such a "whim". Everything is very simple, because if you use leaded fuel, then in this case you will have problems with the engine, because it will simply fail.

It is important to remember that oil and gasoline directly must be mixed in exact and strict proportions. In order to answer the question what is the proportion of oil and gasoline for chainsaws, you must first of all catch the fact that if you pour in too much oil, then in this case you cannot avoid the occurrence of carbon deposits on candles and pistons.

Lack of oil will cause seizures on the pistons, as well as a quick breakdown of the engine itself.

Now let's deal with an equally important task that concerns what actually needs to be done with this kind of manipulation. So. Today, specialized stores have special canisters that have certain divisions of a dimensional character, as well as a pair of holes - one is for oil, the second for gasoline.

The process itself is not something complicated, since everything is extremely simple: you pour the necessary ingredients into the container, tighten the lids and mix thoroughly by tilting the container. Most owners use plastic and glass bottles for this manipulation.

But it must be remembered that through such measures, static electricity can be generated so you have to be extremely careful. Remember that no drops of water or any foreign elements should get into your mixture. In addition, do not forget the nuance that you should store the finished oil-fuel mixture for no more than twenty-five to thirty days.

Summing up…

In this article, you got acquainted with what proportion of oil and gasoline for chainsaws for correct operation(for example, splitting trees) and how to properly dilute gasoline with chainsaw oil, as well as how to refuel a chainsaw and what should be the ratio of oil and gasoline. Therefore, following all the tips and recommendations prescribed above, you will undoubtedly be able to personally carry out this process.

Rules for the preparation of the fuel mixture

The process of preparing the fuel mixture should begin with a detailed acquaintance with the instructions attached to it. As mentioned at the beginning of the article, some drivers, who, in their opinion, have incredible experience, do everything “by eye”. Of course, over time, every driver knows how and what needs to be done, however, each mixture has its own differences, so it will never be superfluous to get acquainted with the advice from the manufacturer.

The main rules for the operation of the fuel mixture include:

Never reduce the proportions of oil to gasoline. Oil is an expensive component, so many people decide to save on it. However, an insufficient amount of oil in the mixture leads to severe heating of the piston and engine cylinder. Because of this, scoring appears, which ultimately leads to the need for serious repairs.
Do not use too much oil in relation to gasoline. An increase in oil proportions is also detrimental to engine performance. Excess amount oil leads to an increase in soot and rapid wear of the motor mechanism. Repair in this case will cost as much as in the first case.
Do not store the prepared mixture for more than 30 days. Otherwise, it loses its properties and the use of such a mixture can harm the engine.
Dirt, dust and other mechanical debris must not be allowed to enter, due to which the engine may become unusable.

Proportions and mixing process

How to determine the proportions for mixing oil with gasoline? Standard proportions should be indicated on the oil container. The amount of oil used may vary depending on the manufacturer, but 1:40 or 1:50 ratios are often used. A slight deviation from this ratio is allowed - this will not entail serious consequences.

Having determined the exact proportions, you need to proceed to the direct preparation of the mixture. In what way can this be done? For this, various containers are suitable. Important: in no case should you mix fuel with oil directly in the gas tank, pouring one liquid after another in turn - the mixture is always prepared separately and only then slowly poured into the gas tank.

For mixing, you can use the most various devices, among which:

Special containers for mixing. These are convenient canisters with two separate outlets - separately for gasoline and oil. To prepare the mixture in such a container, you just need to pour the right amount of liquid, close the container and tilt the canister several times. Such devices are very convenient, but they are quite expensive. If you have to mix the mixture often enough, then you should think about purchasing such a container.
Ordinary metal and plastic canisters. Standard canisters are the most practical fixtures. One has only to be careful when using plastic and glass canisters, because when using them there is a possibility of a discharge of electricity. If you need to prepare a small amount of the mixture, you can use a regular plastic bottle.
Hand tools. To save money, many use improvised devices, such as baby horns and even syringes. Such funds are not very convenient, but they cost a penny.

How and where to store the finished mixture?

Manufacturers recommend storing the fuel mixture in a clean container, preferably a metal one. Under no circumstances should the mixture be left under direct sunbeams, because this will lead not only to the loss of its properties, but also to other very backfire. The maximum shelf life of the finished mixture is 30 days.

Depending on how often the car is used, some drivers prepare the mixture once a week, others once a month. Of course, not every owner has the time to constantly measure the proportions and mix the fuel with the oil. It is important to remember that the "fresher" the mixture, the better it is for the engine.

Many use plastic cans and bottles as containers for storing the mixture. It is convenient and practical. There is always a place for a small plastic bottle. However, you should be careful about this. The point is that at long-term storage in a plastic container, the fuel mixture can literally "eat" a hole in it. The process of corroding plastic is very fast. Therefore, it is best to use a metal container.

It may not be as convenient, but it is more reliable. If there is still a need to use plastic canister, then remember that you can store the mixture in it for no more than two to three days. Then it needs to be poured into another container.

Signs of misuse

The use of a contaminated or disproportionate mixture can lead to serious engine malfunctions. If you made a mistake when mixing, it's okay, because the car will tell you about it. You just need to be attentive to some signs, including:

The appearance of dirt and various deposits on the carburetor.
Rapid contamination of the fuel filter located in the gas tank.
Oxidation of the carburetor walls and loss of elasticity of the rubber diaphragm in various parts of the gas tank. This symptom appears only during long-term storage of an unsuitable mixture directly in the car's gas tank.

The formation of resinous deposits in the carburetor area.

At the slightest manifestation of one of the signs, it is necessary to make changes to the mixing process, choosing more suitable proportions. In this way, you can choose the ideal fuel mixture and avoid serious engine malfunctions.

To prepare the correct fuel mixture yourself, which will ensure perfect engine performance, you must use the right fuel, strictly adhere to the proportions specified by the manufacturer, use a suitable container and store the finished mixture for no longer than 30 days. By adhering to these rules, you will prepare the perfect mixture for your car engine.

Video: preparing a fuel mixture for a two-stroke engine

Few know the rules how to dilute gasoline for a chainsaw. The wrong proportion of gasoline and oil, poured into the tank of a two-stroke chainsaw engine and used for a long time, will lead to negative consequences that will affect the operation of garden and sawmill tools. Ignoring the use of an oil-fuel mixture and using pure gasoline instead will lead to premature failure and urgent repair of the saw.

What gasoline to fill in chainsaws

A lot of controversy goes around what kind of gasoline to fill in the fuel tank. For foreign models, manufacturers recommend using 92nd gasoline. Local tool manufacturers, on the contrary, recommend using a lower grade fuel, for example, AI-80. But everyone agrees that it is not recommended to use gasoline with an octane rating of 95 or higher. This is due to the presence in it of special additives (additives) that change qualitative composition fuel, but unlike car engines, the tool has a more sensitive filling. Excess components are deposited on internal parts and when a critical mass is accumulated, they exfoliate and disrupt the operation of the mechanism.

In some cases, a mixture of 92 and 80 unleaded fuel is used for refueling.
The best recipe is to follow the instructions that come with the tool. It usually indicates the “correct” option for this model, and by default, gasoline of the 92nd brand is recommended.

Announcement:

What oil to add to gasoline for a chainsaw

Many chainsaw manufacturers also create their own Consumables, including oils adapted to work with a specific engine. They differ in their composition, quality and purpose. Distinguish between chain and motor oils. They are not interchangeable, so adding chain oil to the fuel tank may damage the tool.
Among a number of brands, it is worth highlighting several designed for 2-stroke engines:

Oleo-mac Prosint;
Stihl and Stihl HP;
2-tact motors;
Kraissman;
sadko;
Husqvarna 10.0.

For 4-strokes, other specialized oils are used, for example, MOL Dynamic 4T or Oleo-mac 4T SAE, etc.
It is important not to use used engine oil under any pretext. It contains particles of worn metal, excess oxides and other components that will cause irreparable harm to the fuel system.

Proportions of oil and gasoline for chainsaws

There are only 3 ways to mix the oil. But in order to carry out any of them, you need to correctly measure the components so that the mixture acquires the necessary technical qualities. Basic aspect ratios:

1/15;
1/20;
1/25;
1/40;
1/50.

In terms of milliliters, 1/50 will correspond to 20 ml of oil per 1 liter of fuel. Others are calculated similarly.
It is not recommended to choose them at your own discretion and measure by eye. You should strictly follow the instructions on the oil packaging or that comes with the tool. If they do not match each other, the one that comes with the saw should be given priority.
You also need to mix them with knowledge of technology. You need to add oil to the fuel, and not vice versa. It has a denser structure than gasoline and can stick to the sides of a container, whether it's a separate mixing container or just a fuel tank.
To obtain the correct mixture, you need to use measuring instruments:

measuring cups or bottles with divisions;
medical syringes without needles;
special branded containers for mixing.

» Gasoline with chainsaw oil - how to dilute and why it is done

The chainsaws of different companies are based on a two-stroke internal combustion engine, which drives the cutting tool set. To power the internal combustion engine, the proportions of gasoline with chainsaw oil are used. Combining gasoline with oil is a mandatory procedure, so if you just bought a tool, then you need to understand the features of its refueling.

Why is gasoline mixed with chainsaw oil?

It is necessary to dilute gasoline with oil in order to avoid failure of the internal combustion engine. The reason for this are design features lubrication systems for two-stroke engines. The design of such engines does not have a chamber for filling engine oil, and if fuel is poured without lubricant, then the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all the listed parts, so it is forbidden to fill in clean fuel.

Gasoline and chainsaw oil must be poured in the appropriate proportions, which makes it possible to effectively lubricate rubbing parts. Lack of lubrication or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, it is necessary from the first day of operation of the tool to refuel it not only quality materials but also keep the correct proportions.

It is important to know! It is required to fill in a two-stroke engine with gasoline with an octane rating of at least 92. Many experts argue that it is possible to fill in Russian or Ukrainian fuel only with an octane rating of at least 95, which is due to its low quality.

In order for the engine to work properly, the main thing is to fill it with clean fuel without pollution.

The ratio of gasoline and oil for chainsaws

The proportions of oil and gasoline for refueling two-stroke chainsaw engines of different brands is 40 to 1 or 50 to 1. This ratio is standard, which is used not only by beginners, but also by experienced sawmillers. It is this ratio for the preparation of the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and piston.

The proportions of the preparation of the fuel mixture

This is interesting! Before mixing petroleum products, consideration should be given to external factors. If the chainsaw is new, then it requires a break-in, and for this you need to add 20% more to the combustible oil than the standard values. 20% more lubricant is also required if the tool is operated at low temperatures.

How much oil should be poured into gasoline in milliliters? Per ml, the proportion of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the right mixture, you should draw 1 liter of gasoline into a plastic bottle, and dilute it with 20 ml of oil. To correctly measure how much oil to pour, you should take a special measuring container and fill it to the appropriate mark. If it is immediately planned to prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios offered by different manufacturers. These ratio values differ slightly, but if you subtracted other values in the passport for the instrument, then you need to adhere to them. A value of 1 to 50 or 40 is standardized. Pour 15 ml of oil per liter of fuel in the summer, and add at least 20-25 ml in winter. Knowing the recipe for preparing the mixture, you should also understand the question of what kind of gasoline to pour into a chainsaw?

Gasoline and chainsaw oil - which is better

Often beginners ask, what is the best gasoline to take for your tool? In order not to make a mistake in choosing, it is recommended to read the instructions for the tool. In the instructions, each manufacturer indicates the appropriate brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, it is not recommended to pour 92 gasoline.

Now let's figure out which oil is better to take for chainsaw motors. For such purposes, special oils are used. It is forbidden to take engine oils of car engines for the preparation of a fuel mixture. For chainsaws, you need to buy lubricant for two-stroke motors, which are on sale not only in specialized centers, but also in online stores.

It is important to know! It must be distinguished that manufacturers produce two types of lubricants for chainsaws - for chains and engines. Chain materials are poured into a separate tool tank, and they are used up to lubricate the chain while working with a chainsaw.

Engine oils for two-stroke engines are produced by the following manufacturers:

Stihl
Kreissman
Sadko
Husqvarna

Usually the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use mining even as a chain lubricant. This will lead to the fact that soon it will be necessary to carry out repairs to the instrument.

Instructions for refueling a chainsaw

Knowing the ratio of the preparation of the benzo-oil mixture, you can start refueling it. The loading instructions are as follows:

First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly
Place the tool on a clean and flat surface. Before unscrewing the gas tank cap, you need to clean or blow out sawdust, dust and dirt
The neck of the tank should look up
Install a small watering can in the neck, then pour fuel
Control the refueling process, as the tank volume is small, so it fills up quickly
Do not fill up to the full maximum, as when the tank cap is closed, the remaining fuel will splash out
After the fuel is filled into the tank, immediately add chain lubricant
The consumption of fuel and chain lubrication is approximately the same, therefore both tanks must be filled at the same time
After refueling, you can start the engine

It is better to start the engine not at the place where refueling was carried out, but to move a distance of 2-3 m. The tool is ready for work, and you can start starting it. How the chainsaw engine starts can be found in this material (link).

What happens if you pour mining into a chainsaw

If you do not want your chainsaw to fail at the wrong moment, use only high-quality fuels and lubricants. Mixing mining with gasoline is prohibited. The reasons for this are the following factors:

Another viscosity of the material, so mining is not able to provide effective lubrication of rubbing parts and mechanisms
The mining contains small metal particles and chips, which, getting into the tank, will lead to clogging of the fuel filter and channel. If the lubricant enters the cylinder along with small particles, they will leave their mark in the form of accelerated wear of the piston rings.
Selection a large number black smoke indicating oil burning

It is impossible to fill in surrogate materials not only in a tank with gasoline, but also in a tank for chain lubrication. What will happen if you use mining in the chain lubrication tank can be seen in the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. If the fuel mixture is improperly diluted, not only the resource of the tool is reduced, but also its performance is reduced.
