Partner chainsaw mixture composition. Caution – falsifier!

The ratio of gasoline and oil for the chainsaw Partner

Over time, each owner of the Partner chainsaw is faced with a deterioration in the operation of the ICE of the tool, as well as a sharp increase in the amount of fuel consumed by him. The first thing to do in this case is to adjust the carburetor on the Partner chainsaw.

partner, chainsaw, mixture, composition

Immediately before setting, you will need to clean the carburetor and all the details located next to it. You also need to rinse or replace the air and fuel filter. After that, in the upper part of the protective cover of the tool, you will need to find 3 regular holes. Inside them are adjusting bolts marked with markings h, l and t. The letters are always indicated on the protective cover of the Partner chainsaw. The right bolt with marking h is needed to configure the quality of the fuel mixture. Accordingly, the left screw is designed to adjust the amount of fuel supplied, and indicated by the letter L. A small spring is worn on the third screw. It is indicated by the letter T, and is needed to adjust the position of the throttle when operating the motor at idle.

Partner chainsaw carburetor setup is performed in this order:

  • At first, the b and l bolts when the saw engine turned off you must completely twist clockwise, and then immediately unscrew them into 1/5 turnover in the opposite direction;
  • Then you need to start the engine engine and give it time to warm up. As soon as the motor heats up, you will need to start turning the bolt L until the ICE does not gain maximum speed. Immediately after this, the bolt must be turned into 1/4 turnover in the opposite direction. If at the same time the idle speed of the motor is too low or very high, then they should be adjusted with a screw T;
  • Next to the saw motor, you need to connect a tachometer. After that, you will need to start turning the bolt H until the engine set the highest revolutions. If the indicators on the tachometer coincide with the instructions in the instructions for the tool, then you can proceed to the last stage of the setting:
  • At the end, you need to make sure that after all the actions the saw chain did not start moving along the tire. If the headset moves, then you will need to start turning the screw T in different directions. As soon as the chain stops moving, you can flood the saw engine.

After adjustment, you need to start the tool again and check the operation of its engine. To do this, press the gas trigger several times, increasing the load on the motor. If the internal combustion engine is steadily gaining and losing momentum, it means that the Partner saw carburetor adjustment is successful.

Learning to dilute gasoline with oil for a trimmer for grass if you do not have or pour oil

If you bought a trimmer for grass, a lawn mower, a motorcycle, a chainsaw and other types of equipment, then you probably know that two.stroke engines are used as power units on them. These motors do not work on pure gasoline, like four.stroke, but on a mixture of gasoline with butter. In what proportion should be diluted gasoline with oil for a trimmer for grass. this question asks for himself every summer resident before preparing the tool for work. We will figure out in detail in this matter, since the dilution of gasoline with oil for a trimmer for grass affects the life of the tool, and improper preparation of the mixture will lead to rapid engine wear. What is the dangerous or insufficient amount of oil in gasoline for a trimmer for grass:

  • If gasoline is diluted with a large amount of oil (above the norm), this will lead not only to a large amount of smoke, but also to the formation of a carbon on the walls of the cylinder and a drop in power. This incapacitance will cause wear of the piston, which will be diagnosed to reduce its performance
  • If gasoline contains an insufficient amount of oil poured into a trimmer for grass, then this is even more dangerous. After all, the working mechanisms of the engine will not be lubricated in sufficient quantities, which will ultimately lead to their rapid wear (rapid destruction of the piston rings and jamming of the motor occurs). With an insufficient amount of oil in gasoline, poured into a trimmer for grass, the wear of the motor will occur ten times faster

So that you do not have to pay for errors at the cost of overhaul of the engine or buying a new tool, it is necessary to fill the fuel of the correct consistency into the tank from the first day. You can find out the ratio in the instructions for the tool, since models of different manufacturers can give different recommendations. Usually this ratio is the following norms:

  • 1 to 25 or 1 liter of gasoline 40 grams of two.stroke oil
  • 1 to 40 or 1 liter of gasoline 25-30 grams of grease
  • 1 to 50. this is added to a liter of gasoline 20 grams of oil

The value of 1 to 50 is considered standard (indicated on canister with butter for two.stroke engines), but it is necessary to rely on it in the most extreme case, since the manufacturers indicate the recommended value of the proportion, and if it is not observed, the operational resource of a two.stroke motor decreases.

In addition to observing the proportion, you must also learn to prepare the mixture. After all, the option of adding oil to the gas tank is categorically contraindicated, although some do so. If you bought a trimmer for grass or a lawn mower, you will need the consumables that you will use to prepare the mixture. Instructions for the preparation of the fuel mixture in a trimmer for grass have the following view:

Prepare gasoline and two.stroke oil, based on the above recommendations for the choice of a lubricant and fuel in addition, for the preparation of the mixture, you need to take a container or container. Typically, a plastic bottle is used for this, the choice of which needs an appropriate approach. It should be clean inside. Using a milk container and other drinks is not recommended

The best option is a container from mineral water it is very important that the capacity has a whole value of volume, that is, 1 or 2 liters, so that you do not have to calculate how much oil is poured into a bottle per 1.5 liters, 1.3 or 1.25 After all, you can easily be mistaken, you can also need a syringe that is used as a measured device for dosing. For such purposes, a regular medical syringe for 10 cubes is suitable

It is desirable that the syringe has an exact measuring scale after preparing the necessary materials, you can proceed to cook

It is desirable that the syringe has an exact measuring scale after preparing the necessary materials, you can proceed to cook

Instructions for the preparation of the fuel mixture in the lawn mower:

  • First you should fill a plastic container. The container is filled with 2 fingers not supplemented to fit the oil
  • The required amount of two.stroke oil is typed in a syringe, and poured into a bottle with gasoline. You need to do just that, and not vice versa
  • After adding a lubricant to the bottle, it requires to close it tightly with a lid and stir. However, take into account that the streaming needs oil with the designation “Pre mix”. If the container “Self mix” is on the container with oil, then you do not need to shake the container, and after connecting the substances, you can pour them into the tool tank

After preparing a fuel mixture for a trimmer for grass, it remains to season the tool, and start work. How to correctly refuel trimmers for grass, lawn mowers, chainsaws and other types of motorcycles, consider in detail.

DLE Dilutions and use in the trimmer only fresh gasoline is used.


The new chainsaw immediately after the purchase is slightly less performance than similar models that have been in operation. The rated power of the engine is achieved only after the production of 6-10 full fuel mixture tanks.

However, it should be noted that the the imported chainsaw (Husqvarna, Stihl, Partner) has significant differences in front of domestic chainsaws. So, for example, you do not need to produce several tanks of the fuel mixture at idle. The running-in consists in cyclic work with minimal load on the motor: first, the soft wood species are sawing for 1-2 minutes, then 20-30 seconds of work in idle mode. Thus, the formation of a large layer of tanning that occurs during prolonged operation of the chainsaw at idle is prevented.

Partner Formula 500 in action. Power in old chain saw !

The rupture of the chainsaw must be carried out on high-quality AI-92 gasoline without any additives and company oil, which is recommended by a specific manufacturer. Find out what and how much oil in gasoline for the chainsaw you need to fill, you can in the instructions for the chainsaw itself.

In no case should you dilute with gasoline products designed for low.speed engines, as in the photo.

The proportion of oil and gasoline for the chainsaw of the corresponding brand:

  • STIHL with a capacity of less than 1.5 kW. (1:40);
  • STIHL with a capacity of more than 1.5 kW. (1:50);
  • Partner. (1:33);
  • Husqvarna with a capacity of less than 1.5 kW. (1:40);
  • Husqvarna with a capacity of more than 1.5 kW. (1:50);
  • Jonshed. (1:33).

The prepared mixture can be stored for up to two months, and then there is a risk of engine breakdown due to the inevitable decrease in the octane number of gasoline.

The ratio of gasoline and oil for the chainsaw during normal operation

Any chainsaw is required to work fuel-oil mixture-gasoline and two-stroke lubricant.

  • fresh, without muddy sediment, uneliled;
  • Benzospict (ethanol) should not exceed 10 %, and methyl ether methyl etcher (MTBE). no more than 15 %;
  • The octane number should not be lower than 92;
  • Alternative fuel or additives is not allowed.

To understand what oil in gasoline for a chainsaw must be poured and how much can be diluted, it is necessary to look for a manufacturer of the necessary saw on the label of a corporate product. In no case can ordinary machine oil be diluted. this can lead to the appearance of a carbon fiber, abundant sinking and increased engine wear.

partner, chainsaw, mixture, composition

Ideally, you need to use only branded oil. Manufacturers of chainsaws, of course, do not produce their chemistry, but they monitor the quality of certain brands, and this fact is indicated on the packaging. Also on the label indicates what proportion to mix gasoline with oil for a chainsaw. Often this:

For mixing, a gas-resistant container is taken, into which a liter of 92nd gasoline and 30, 25 or 20 ml of oil is poured, respectively. For convenience, the liquid can be measured using a twenty.type medical disposable syringe (in this situation, it will be quite compiled for reusable use). The video shows how to dilute oil with gasoline for a chainsaw.

When mixing, you need to understand how to dilute gasoline with oil for a chainsaw:

  • Can only be mixed in clean dry containers.
  • In no case should you mix directly in the tank of the chainsaw.
  • It is necessary to first fill the gasoline into the container, and then the oil, otherwise it can “stick” to the bottom and mix in insufficient.
  • Do not change the ratio of components. Excess lubrication leads to unnecessary embezzlement, and the deficiency. to overheating and the appearance of defects.
  • The use of gasoline with octane number above 92 is economically impractical, especially since 98 often have additives that negatively affect the chainsaw engine.
  • In no case should you apply the development.
  • It is recommended to mix gasoline with butter exactly so that nothing remains after work, since over time the octane number of gasoline falls.

In order for the chainsaw to start “from the half.turn”, it does not stall and does not break too often, it is necessary to strictly observe the ratio of the mixture poured into the gas tank. How to breed gasoline for the Stihl, Husqvarna, Partner and other foreign manufacturers in the instructions themselves to these devices. At the same time, gasoline is usually taken 92, and the gradual oil is two.stroke.

Typically, in the mixture, the oil is two percent or one fifty part of gasoline. However, various manufacturers reserve the right to recommend other proportions of components to users. For example, the Partner brand has an oil ratio. gasoline 1:40, and 1:25 to Chinese models.

The proportions in the mixture must be withstanded accurately, otherwise the excessive amount of oil will entail an additional carpet, the engine will begin to work for wear, and the person engaged in the sawing will breathe vapor from irrevocated oil. Also, due to excess oil, the octane value of the composition is reduced. In the case of insufficient filling of the oil into the fuel mixture, rapid wear of the bearings will occur due to friction and lifting metal surfaces.

The resulting mixture should be spent within a week, at best in a few days, due to the breakdown of oil additives. The most ideal option for consumption of the fuel mixture is one day. Когда работы по распилу уже выполнены, остаток состава из бака нужно слить и использовать для других нужд. Then you need to start the saw and idle gasoline from the carburetor at idle.

Make the correct measurements of the components of the mixture will allow the measuring containers available on sale, they are presented in the photo below. The smallest capacity of the produced volumes per liter. Therefore, it is possible to make measurement independently with a different amount of fuel mixture. To measure not a significant volume of filling of the composition, you can use the measuring laboratory cylinder.

How to make measurement yourself

To make the measurement with your own hands enough to take a hard plastic bottle with a volume of half a liter or liter. Then, water is poured into this container in the amount of 102,204,306,408,510,612,714,816 milliliters alternately. At the same time, each time making a label with persistent paint on a bottle. Further, at the level of the marked features, numbers are written 2.4,6,10,12,14,16,18. The oil is measured with a syringe without a needle with a volume of 10.20 milliliters. In this marking, a step of 102 milliliters for oil ratio 1 to 50 is taken in this marking. Observing this principle, the proportions can be changed depending on the recommendations of the manufacturer.

To prepare the fuel mixture, the necessary volume is selected, for example, the division with the number 3. First, three milliliters of oil are typed in the syringe and poured into the measurement. Then gasoline is collected in it to wash off the oil, and then gasoline is added to the measured volume to 3. The composition is well shaken and refuel into the chainsaw. The inconvenience of such a measurement is in a manipulation with a syringe.

Measurement with the established volume

You need to take a bottle with a narrow long throat, like a glass. At the upper level of the neck, a label is applied to which water is poured. Then this fluid is required to be transferred to the laboratory cylinder to determine the exact volume. At the level of the label, the numerical value of the amount of fuel mixture is placed. The resulting volume of water is divided by 51 and multiplied by 50, this will be the volume of gasoline, which is poured and the second lower mark on the bottle is also noted. Oil is added to the upper mark. Then the mixture is mixed. the chainsaw can now be refueled. The video shows such a process. To refuel the tool with different volumes, it is advisable to prepare several bottles.

Ural chainsaws, friendship is not whimsical in everyday life and are refueling “with a bang” with fuel mixtures made at home, when the correct proportions are observed. For more technological imported saws, mixtures are suitable, which include oils of these companies: STIHL, Husqvarna, Partner.

Preparation of a mixture of fuel and lubricants

In order to know exactly how to breed gasoline, making a mixture for a chainsaw, it is best to pay attention to the information specified by the manufacturer. Also, the most popular proportions for saws, the power of which exceeds 1.5 kW, is to use oil 50 times less than gasoline. Although there are various exceptions from this rule. Chinese manufacturers are focused on the proportion of 1 to 25, while the famous company Partner is 1 to 40. Companies such as Husqvarna recommend using 25 milliliters of oil per 1 liter of gasoline on their devices. STIHL chainsaws also work well on the prepared mixture in such a proportion.

Problems that may give a violation of the ratio of lubricants:

  • rapid wear of the surfaces of the details of the saw that carry out friction;
  • acceleration of failure of bearings;
  • reduction in the resource of the mechanism;
  • Reducing the functionality of the device.

The mixture is best prepared before it must be poured directly in the saw. But completely disadvantaged gasoline with butter for more than a few days in the tank is not recommended. The additives that are in oil, with such storage, are quickly destroyed. It is better to drain the mixture from the tank, and the residues are obtained at idle.

It is best to breed in a special canister, which has different holes for each of the materials. Gasoline should be poured into one part of the container, while oil is in the other. When tilting the canister, the components are mixed and a high.quality correct mixture is obtained. Diluting gasoline in plastic or glass containers is real, but there is a risk that ignition and even explosion can occur. But any plastic container can be spontaneously bending, which can lead to a random ingress of the mixture on a chainsaw or hand of a person.

It is necessary to breed gasoline for a chainsaw in a clean and dried container. Getting any particles or liquids into a container is an unacceptable. Before diluting gasoline for a chainsaw, you need to wipe the container and carefully check it.

The table shows the proportions of oil and gasoline for the chainsaw (how much should the oils in millyillers per liter of gasoline):

We need high.quality components

Practice proves the influence of the quality of the prepared mixture, taking into account the necessary proportions on the operational period of use of the tool, power, performance:

  • It is not recommended to use the components that have completed the shelf life.
  • It is especially important for the components of gasoline and oil. not to use the components obtained on the basis of gas condensates, since the molecular structure contains harmful, for ICEs, rush and water and water.
  • Partial discrepancy between AI-92 international standards. AI-95 brand is saturated with additives that extinguish the detonation moments.

The noted deficiencies limit in time the operational resource of manual chainsaws, the ICE of which work at complex consistency of the combustible mixture.

How to refuel a chainsaw

Consider how to refuel a chainsaw. If the saw is seasoned incorrectly, this may threaten the life and health of the device operator.

There are rules that must be executed when refueling a saw:

  • You can not pour oil and fuel mixture;
  • the place where the sawing will be refueling should be even;
  • The place should be removed from the zone where the device will be operated by more than 2 m;
  • The site should be located far from the fire; You can’t smoke in this place;
  • At a time when a fuel tank is filled, you need to fill the oil tank, which is designed for automatic lubrication of the chain; You can distinguish containers by special icons;
  • Before pouring, it is necessary to wipe the neck of the capacities with a rag;
  • During operation, lubrication and gasoline can not be allowed, so you need to be neat when the canister covers is unscrewed; When refueling, it is better to use a funnel;
  • Caution should be observed when tightening the cover with the latch;
  • Experts advise filling the container not completely, but leave a little free space.

During the operation of a properly refined chainsaw, it is necessary to regularly check the tightness of the containers and the operation of the motor. If the chain heats up greatly, or gasoline is consumed too quickly (faster than oil), this should cause alertness. Before starting work, the chainsaw is performed.

With proper operation of the 1 tank, the gasoline tank should be enough for 30 minutes of operation of the device with the maximum load. When gasoline ends, the lubricant in the second container still remains, but in a small amount.

Storage recommendations

The mixture must be prepared in the amount that is necessary for the implementation of a small volume of work, since with prolonged storage of the solution its qualitative characteristics worsen. The prepared mixture must be spent for several days.

The fuel mixture, which was stored for about a month, reduces the characteristics of the engine operation. Smolish substances are formed in nodes, and soot appears, piston rings lose mobility. The largest shelf life of the mixture is no more than 2 weeks. During this period, the solution will not lose its quality. If the air temperature is more than 25ºC, then the shelf life of the product is reduced to 10 days.

Some experts allow the use of overdue mixture to save. To do this, it can be spent gradually, gradually mixing in a fresh solution in a volume of not more than 10% of the total amount of the mixture. The finished gasoline mixture must be filtered.

If you follow all of the above recommendations, then you can ensure reliable operation of the chainsaw. Also, when performing work, it is necessary to observe safety precautions, since the chainsaw rotates with high speeds and, in case of violation of the operating rules, can be a danger to the worker himself and the people around him.

The ratio of oil and gasoline for the chainsaw

Each company engaged in the production of chainsaws sets up engines and basic carburetors to work with different lubrication. Therefore, the proportion of oil and gasoline for the chainsaw may vary slightly.

Most often, when mixing fuel with butter, manufacturers advise using 1:50 proportions, or 1:40. This means that 1 part of motor lubrication must be mixed in 50 or 40 parts of fuel, respectively.

Translating the proportion into a more affordable wording is quite simple. For example, 1 liter of fuel contains 1000 ml. If 1000 ml divide by 40, then it turns out 25 ml. This means that 1 liter of gasoline will need to dilute 25 ml of grease. The same formula must be used when the manufacturer recommends preparing the fuel mixture exclusively in a ratio of 1:50. To do this, 1000 ml must be divided into 50, as a result of which it turns out 20 ml. This means that in one liter of fuel, 20 ml of motor lubrication should be diluted.

It’s a little different about Chinese chainsaws. Their manufacturers advise breeding gasoline for a chainsaw in a ratio of 1:25. This means that owners of Chinese instrument need to stir in 1 liter of pure gasoline exactly 40 ml of lubricant. This ratio is due to the fact that these chainsaws are slightly inferior to their Western counterparts in terms of assembly and selecting components. In the engines of American, European and Japanese models, the distance between cylinders and pistons is much less than that of chainsaws from China. In this regard, the amount of lubrication required to work the first. far less.

Preparation of fuel mixture for a chainsaw


Gasoline should be with an octane number no less than AI92. You can also fill in AI95, but its quality at our gas station leaves much to be desired, so if you are not sure of the 95th, it is better to take gasoline AI92 gasoline to dilute gasoline into a chainsaw. You should not take gasoline in the same way for a long time in the canister, tank or any other capacity. Gasoline for the preparation of the fuel mixture in the chainsaw should be fresh, otherwise it loses its properties, in particular the octane number, and even if you run the chainsaw on such fuel, it will not give out full power. And the saddest thing in this case is that the failure of the chainsaw due to poor.quality fuel is considered a non.warranty occasion and leads to expensive repairs. Sometimes it’s easier to buy a new chainsaw than to repair it after such a breakdown!

Read more about gasoline for chainsaws here:


Oil for 2-stroke engines according to the American Petroleum Institute (API) classification, the American Oil Institute has an API-TB class, there are also API-TC oil oils, but they are designed to work with less loads than most of the chainsups we common. If we take the classification class of Japan Automobile Standards Organization (JASO) Japanese standardization organization in the field of automotive industry, then focus on JASO-FB and JASO FD classes (see.Table 1 below.).Not in any case do not use oil for four.stroke engines! Remember that in a two.stroke engine the oil should be completely burned, which means it is better to take synthetic oil, since it gives less smoke and burning residues. And if you pour oil for four.stroke engines in your chainsaw, which will not burn completely and as a result of the fog, then you will fail. The best thing to be guided by when choosing oil for a chainsaw is an instruction for her.


When preparing a fuel mixture of gasoline and oil for a chainsaw, be sure to see the manufacturer’s recommendations. Why is it so important to observe these recommended proportions? With a small amount of oil in gasoline, the cylinder and the piston will occur and the bulletin will occur, and this is the exit of the CPG and repair. If there is a lot of oils in gasoline, then this is a dozen and the failure again.Each manufacturer has its own recommendations on proportions (see.Table 2 below). Try not to store the finished mixture longer than a month. Do not store it under direct sunlight and openly. Avoid water and dust, this will lead to the failure of the carburetor, since the fuel filter is often not able to completely clean the fuel.

Since they often come from search engines at the request of the same “how much oil is pouring 1.2.5 liters of gasoline”, then I add another table under which you can find out how much oil to gasoline according to the accepted proportions. The proportions can be viewed in table 2 or, more precisely in the instructions for your chainsaw.

Fuel mixture dilution devices

Of course you can use a canister, a syringe or a measured bottle, but there are more convenient options. It is worth noting that, for example, STIHL oils are produced in 2 types of packaging- with a dispenser and without. With a small price difference, a bottle with a dispenser greatly facilitates the process of making the mixture. There are also many different cans with a dispenser, with departments for oil and gasoline separately. All these devices reduce the period of preparation for the launch and work of the chainsaw.

STIHL canister with oil and gasoline departments

This canister has two departments for storing oil and gasoline separately. A capacity of gasoline with a volume of 5 liters, and the oil container has a volume of 3 liters. Often, many owners of a benzo.tool with two.stroke engines in this canister carry oil in the same department, and in the other a ready.made fuel mixture.

Husqvarna canister with oil and fuel mixture departments.

Husqvarn canisters have a feature: the oil container can be disconnected from the main and used separately.

STIHL oil bottle with dispenser.

This bottle, as can be seen in the photo, has two traffic jams. One plug allows you to pour oil into any container directly, and the second is located on a special submachine room. The tilt of the bottle you allow the oil to get into this department, at which risks are applied to the necessary volume. I must say that this is a very convenient function and the difference in price between bottles with a dispenser and without small.

Partner 350 chainsaw. malfunctions and their elimination

Partner’s garden tools can occur for various reasons, the most common of which are improper operation and mechanical stroke. To eliminate the malfunction, you will need to determine its exact cause in advance. After that, you can start independent tool repair.

Partner 350 chainsaw starts up and stalls

There may be several reasons for this malfunction. Most often, the tool engine starts up and immediately stalls due to the blockage of the factory saopun, as a result of which the fuel is entered in the engine cylinder in a sufficient amount to work. To eliminate the breakdown, you will need to remove and clean the sapphon. If it is damaged, then it will need to be replaced.

Another reason is the lack of contact with a candle with a cap of electrical wiring. This can happen due to a mechanical blow or formation on a candle of carbon fiber from motor oil. To repair the Partner 350 chainsaw, the candle will need to be removed and cleaned. In some cases, a complete replacement of the candle can help.

The third cause of the malfunction is the strong suction of the standard muffler of the chain saw. Over time, a carpet forms on its walls, which prevents the exhaust from the engine. As a result, gases accumulate inside the motor and interfere with its good operation. To eliminate the breakdown, it is necessary to remove the silencer to clean it with compressed air. You will also need to disassemble the motor and blow its cylinder.

Partner 350 chainsaws do not start. how to eliminate the malfunction?

If this breakdown is found, the first thing to inspect is the condition of the air filter. If a large amount of dust has accumulated on it, then the filter will need to be washed using pure gasoline for this.

Another common cause of the malfunction is the problems with the ignition system. To repair the chain saw, you need to remove its left protective cover and install the correct gap between the flywheel and the ignition coil.

In some cases, replacing the fuel mixture will help to solve the problem. To do this, the used fuel will need to be drained and pour a new mixture of pure gasoline and engine oil into the tank.

What to do if the chain is not lubricated on the chainsaw Partner 350?

If the Partner 350 chain for the chainsaw has ceased to be lubricated with oil, then this can lead to overheating of the tire and rupture of the saw headset. Ignoring this problem is also fraught with increased engine load, which can lead to its breakdown.

The first thing that needs to be examined in the absence of lubrication on the chain is an oil pump. Over time, teeth on its drive are erased, which can also occur due to clogging of the pump. It is usually impossible to restore the element, therefore it is best to replace it.

Often, lubricant does not fall on the chain of the chainsaw Partner 350 due to clogging of oil tubes. In this case, the hoses will need to be replaced by processing the places of their joints with the fittings sealant.

Pour a candle on the chainsaw Partner 350

Those owners of chainsaws are faced with this common problem that add too much motor oil to the fuel mixture. In the cylinder, it does not have time to burn, so part of the lubricant settles on the candle and other important elements of the garden tool.

To eliminate the breakdown, you need to remove the factory candle, clean it from soot and dry it. After that, you need to blow the cylinder of the factory engine of the chainsaw, several times sharply pulling the starter cable.

Next, you need to inspect the condition of the carburetor and fuel hoses. Often the oil enters the candle due to the loss of the system tightness. This occurs as a result of a break in one of the tubes or breakdown of the oil pump. To repair the Partner 350 chainsaw, you will need to replace all faulty spare parts of the fuel system. After that, you need to install the candle in place, start the tool motor and check its work on idle, low and high speeds.

How to breed properly?

The figures of breeding proportions are not in vain given with such accuracy. That is, it is not said that “take about such and such an amount of oil”. Do not observe the exact proportion by eye, so you have to use something that will allow you to measure the exact amount of oil and gasoline.

Complete with some inexpensive chainsaws are usually a measured tank with risks. As a rule, it has several scales for different proportions. Or one, if the manufacturer implies that this tank will only be used with a saw with which it comes in the kit. There should be two horizontal risks on this scale. The lower one shows the level to which gasoline needs to be poured. Upper. level to which the mixture should reach after adding oil to gasoline.

For more accurate measurement of oil, you can use a medical syringe. Preferably at least 20 ml.

In general, pour gasoline into a measured container, add the desired amount of oil measured with a syringe and shake.

The preparation of the mixture must be done in a separate container, and not directly in the tank of the chainsaw. Otherwise, the oil, not having time to dilute with gasoline, can get into the carburetor, which will complicate the factory, up to the need to remove the carburetor and its cleaning.

  • The specifics of this lubricant consists in the use of internal combustion with air cooling in high.speed engines, which are equipped with a chainsaw for home and a professional class.
  • Depending on the time of the year, for the preparation of the combustible mixture, motor oil of different densities is used, which retains the characteristics in the temperature range indicated on the label.
  • For use, branded oils are recommended, which provide a complete lubrication of the piston group and a crooked-shaped mechanism in all operating modes of the power unit.
  • Brand products are different in color. In particular, Calm mineral oils have red, synthetic color. Husqvarne branded motor oils are blue or green.

Even with a lower cost of mineral oils, it is recommended to use the advantages of synthetic counterparts for the preparation of high quality fuel mixture.

Risks of using fuel and lubricants substitutes

Features of the design of the ICE chainsaw of a domestic and imported assortment exclude the use of more affordable substitutes for biofuel and gas condensate. The productivity of such fuel is far from ideal.

According to various sources, counterfeit lubricants make up 8 to 15% of the total sales of motor oils. Only an experienced specialist can distinguish original products from fakes.

To eliminate potential risks of early failure of the saw. It is recommended to purchase supplies in company retail outlets and dealerships.

With all external similarities, it is forbidden to use oils for two.stroke internal combustion of mopeds and light motorcycles for the preparation of a working fuel mixture. The use of not recommended lubricants can lead to a guarantee for maintenance.

Features of the preparation of the mixture

For security reasons, it is recommended to prepare the fuel mixture in a non.unit metal canister.

  • Recommended proportions of gasoline and oil for each model are different. In most cases, the ratio is 50: 1 and 40: 1. Basils operating on a mixture of gasoline-oil in a ratio of 25: 1 are much less common.
  • According to manufacturers of branded chainsaws, their products do not need to break. However, in the first hours of work, experts advise to operate a new chainsaw on the fuel mixture with high m oil and, if possible, in sparing mode.

For the preparation of the working mixture, containers with dispensers are convenient. The selectivity of fuel filters at gas stations in some cases leaves much to be desired, so it is recommended to filter gasoline through suede or non.fiber material.

Following these recommendations will save you from spontaneous failure in the work of your carburetor equipment.

The specific characteristics of mineral or organic chain oils are focused on lubrication and cooling of besieged dust, so they are not suitable for the preparation of the fuel mixture.

Recommended sequence

According to the standard fuel mixture preparation technology, the estimated amount of oil is poured into a half.filled tank.

The mixture with a closed cork is thoroughly mixed, after which the remaining gasoline is poured. This sequence contributes to the uniformity of the composition.

It is advisable to prepare fuel for a chainsaw in an amount sufficient for one.time operation. The finished composition at a standard temperature of 20 ° C can be stored for no more than one month. At higher temperatures, the expiration date decreases to 2 weeks.

The mixture with the expired shelf life initiates the formation of tarry compounds, contributing to the clogging of sopels, the formation of soot and the limitation of the mobility of the piston rings. In order to save money, the re-executed composition can be consumed by adding up to 15-20% of the total volume to the fresh mixture.

Gas and oil proportions

For the normal operation of the oil engine, very little is required. Its number is always determined in percentage ratio, since the gas tank in saws can have different containers. In addition, many operators prepare a mixture with a small margin, especially if serious work is ahead. After all, one tank for modern tools, for all economicality, is rarely enough more than 1 cubic meter of firewood.

This is a standard due to the high quality of the manufacture of modern engines. Characteristic of most modern saws of German, Swiss, American, Japanese, Italian production. In a word, all saws released no more than 10 years ago by world famous brands-Husqvarna, Stihl, Oleo-Mac, Makita, Echo and others-will require just such a proportion.You can find out about this from the instructions.

However, many purely chinese saws are also influenced by advanced processing and assembly technologies. So, many saws of domestic brands collected in the Middle Kingdom also work on mixtures 1:50. For example, on the recently released bison models, the proportion label appeared in the form of a cardboard flag right on the handle of the starter cord, apparently for those who do not like to look in the instructions.

This ratio is often called “rocker”. This means that after buying a new saw, it will be necessary to pour a mixture more enriched with oil in the gas tank. At this time, the moving parts of the cylinder-piston group are rubbed, in the process a large proportion is required compared to the usual. After burning a pair of three tanks in a sparing mode, you can switch to the ratio recommended by the manufacturer.

Also, 1/40 proportion is generally accepted by some manufacturers, for example, in Partner chainsaws. Given that the oils here are slightly more than in the previous version, a slight excess of the norm will not damage any engine. When using high.quality fuel and lubrication, another question arises. the price of fairly expensive consumables.

To date, it is considered obsolete. Widely used in domestic chainsaws of the old structure like friendship or Urals. Today, it is still a monk to meet her in some Chinese Nunemo chainsaws or branded retail chains. However, every year the number of such goods is reduced and amounts to the most budgetary and low.quality niche of a benzo.tool

In addition, for such products, it is not important how expensive and high.quality oil is flooded into the gas tank. the engine resource is still shamelessly small in any case

Oil and gasoline proportions

The exact ratio of oil and fuel is indicated in the instructions for the chainsaw or on its packaging. Equally bad both do not add and pour oils. If you use the material and saw of the same company, you will need to add 50 parts of gasoline to one part of the oil. If the brands are different, it is better to reduce the amount of gasoline to 40 parts.

Follow not advice from the Internet, namely the information specified in the instructions for the chainsaw. Different manufacturers recommend different proportions of materials, the ratio can be 1:30 or even 1: 100.

It is critical to observe the exact ratio of gasoline and oil. To measure the correct volume, you can focus on the dispenser on the packaging with butter or use a medical syringe

You can also find special mixing containers on sale, which will help to measure the volume of both means.

It is better to prepare the mixture in a volume necessary at once. According to the recommendations of technologists, in a mixed form, the mixture cannot be stored for more than three days. With prolonged storage in the mixture, tarry deposits are formed, combustible properties deteriorate.

AI-92 fuel is most suitable for this mixture. Different additives are often added to AI-95, you can find many fakes.

Expert opinion Kulikov Vladimir Sergeevich

Dilute fuel and oil must be in dishes made of metal or dense plastic, which does not react with oil products. Food plastic cannot be used, since under the influence of gasoline it will decompose and change the properties of the fuel mixture.
