Chainsaw chain oil consumption. Chainsaw chain oil. What and when to pour? What is the oil consumption for chainsaw chain lubrication

Very often when selling a chainsaw, the question is: "What kind of oil to fill in to lubricate the chain?". The most common answer is: "Anything, except for working off." This is absolutely true, but there are some nuances .... For example, sellers often offer to buy chain saw oils from chainsaw manufacturers or designed specifically for this purpose. This makes sense, as a rule, at low temperatures or when you pay great attention to protecting the environment.

Chain oil

In other cases, it is quite possible to replace the oil for chain lubrication with anything other than mining. However, there is one more nuance…. Often users have a question - “Why is the oil consumption for chain lubrication more than fuel mixture? After all, their consumption is interconnected? It should be borne in mind here that chainsaw manufacturers consider the oil consumption for chain lubrication by filling in their branded oil. And the consumption of any other can differ both up and down.

On many chainsaws, starting from semi-professionals, it is possible to adjust the oil flow for chain lubrication. This is done by adjusting the output of the oil pump.

If such an adjustment is not provided, then the settings are initially from the factory. How to check if the oil consumption for chain lubrication is normal on your chainsaw? It is necessary to start the saw, give it gas and bring it to a board, log or other surface that is horizontal. The running chain should scatter oil particles to lubricate the chain and leave a thin, even trail of oil.

When to use special chain oil

The use of special oils for chain lubrication will be justified in the following cases:

You have a new chainsaw under warranty and to maintain it, you must use oils recommended by the chainsaw manufacturer. Otherwise, if, for example, the oil pump fails, the repair will not be carried out under warranty. This is especially true for expensive professional chainsaws.
Do you respect environment and prefer not to pollute it once again. In this case, oils with the prefix "bio" are suitable.
When working at critical temperatures.

Consider several types of oils from different manufacturers and sort them by price category, environmental friendliness and container volume.

Choose for chainsaw

Any two-stroke chainsaw engine runs on a mixture of gasoline and oil, respectively, how long it will last depends on the properties and the correct consistency of these components. Also in chainsaws, you need to lubricate the bar and chain, and the quality of the lubricant is not the last factor affecting the duration of use of these parts of the chainsaw. In this article, we will talk about the oils that Stihl produces and advises for use not only on chainsaws of its own production.

Stihl grease for two-stroke engines

Stihl engineers develop oils that are normally suitable for all two-stroke engines installed on Stihl chainsaws and trimmers and not only. The line of lubricants for Stihl two-stroke engines contains several product options:

Stihl HP;
Stihl HP Ultra;
Stihl HP S

Stihl HP review

Stihl HP is a chainsaw lubricant designed for high performance requirements and designed to lubricate the internal parts of the motor during its operation. It is made on a mineral base and has good combustion performance (has a low level of emission harmful substances during combustion).

Genuine Stihl HP is reddish in color and comes in Stihl branded packaging.

It comes in several packaging options, the most popular of which is a bottle of one litre with integrated dispenser. You can also meet Stihl HP in cans of 5, 10 and 50 5 liters..

The price of Stihl HP Ultra is actually twice the cost of Stihl HP and for this reason it is the least popular in our country.

The shelf life of the Stihl HP Ultra is four years.

HP Super

Designed for high performance and 4-stroke 2-MIX engines. The properties are a little worse than those of the HP Ultra, which is why the HP Super is no longer available at Stihl dealers.

The proportions of the preparation of the fuel mixture

Very often people ask the question, how much oil per liter of gasoline is considered the norm. It is simple to answer it, because in the annotation for any Stihl chainsaw, it is also indicated on the packaging of the additive that when using Stihl's unique products, the proportions of oil and gasoline should be 1:50. This means that on one litre fuel, you need to add 20 ml of additive.

Which oil choose

If you are a regular chainsaw user and do not use it daily for 6-8 hours, while working only in the summer, then you can use a regular Stihl HP to prepare the fuel mixture for your chainsaw. The optimal ratio of price and quality of the lubricant has made it popular with millions of gas tool users.

Stihl HP can be used to mix any two-stroke engine, including moped and boat engines.

Oil for Stihl chain (oil review)

The Stihl oil line for chain lubrication includes three types of products, these are:

When working, it is necessary to use the type of lubricant that best suits the conditions and duration of work. Consider each of the oils for the Stihl chain in more detail.

forest plus

Mineral oil for lubricating the ForestPlus chain, this is a quality product that creates a reliable film on the bar and on the chain links, which is well retained even at the maximum speed of the chain rotation.

Packed in three types of containers, liter bottle and canisters of five and twenty liters.

ForestPlus has the shortest shelf life among oils in the Stihl line, which is only three years under proper storage conditions.

BioPlus chain oil review

BioPlus is made on a plant basis, which allows it to decompose when it enters the soil in the shortest possible time. It is this property that is marked with the European sign environmental safety. According to the information available on the manufacturer's website and is official, BioPlus has been tested according to OECD 301 B.

Synth Plus

SynthPlus, it's semi-synthetic oil, which retains its properties even under the most difficult conditions. It is able to maintain performance at a temperature of minus 25 degrees. SynthPlus mixes well with BioPlus, making it easy to switch from one type of oil to another.

SynthPlus, has a long shelf life, which, when proper storage reaches seven years of age. SynthPlus oil color, brown.

Stihl SynthPlus is packaged in containers of the same capacity as BioPlus.

Which oil choose for chain

The best option for chain lubrication oil is BioPlus and it should be chosen by those who saw with a chainsaw from time to time. The optimal price and quality of BioPlus have made it the most popular chain oil in the Stihl range.

It is also worth remembering that BioPlus does not harm the environment, because it is made on a plant basis and decomposes in the shortest possible time, which is also important when working with a chainsaw on your own site.

How to distinguish fake oil Calm

Attackers do not miss the opportunity to make money on the sale of counterfeit products of a well-known brand. Oil Calm is no exception. Most often you can find fake Stihl HP, because its sales volumes are the highest of the entire Stihl line of lubricants.

In order to distinguish a fake from the original, the Stihl company released a special brochure on which it recorded all the main differences between the original and the fake.

Also, we invite you to watch a video in which specific example shows how a package of high-quality Stihl oil should look like and how to distinguish a fake.

How to dilute gasoline with chainsaw oil How to dilute gasoline for a chainsaw? As a fuel for a chainsaw, gasoline with the highest octane number is used: AI-92, in other words, AI-95. dilute chainsaw gasoline for 1 liter of gasoline, add 30 g of special engine oil. The purchased mixture is poured into a special fuel compartment. To develop...

To understand which chainsaw chain oil to use, you need to understand the principle of operation of the tool and its characteristics. The chainsaw has become an indispensable tool in everyday life. modern man. And for proper operation, like any tool, it needs timely inspection and prevention. A chainsaw is, in principle, an unpretentious tool. And it doesn't cost much. What is worth only the ratio of the required oil to fuel, equal to 1:40.

It is necessary to determine the type of chainsaw to select the oil.

In today's market, the range of tools is very wide. Domestic and foreign manufacturers produce 2- and 4-stroke engines for chainsaws. The oil consumption in a chainsaw directly depends on the engine used. Many devices are usually import manufacturers, it is recommended to lubricate only branded oils.

IN various types motors have a torque characteristic. The fact is that oil is used in order to reduce tool wear by enveloping the friction points of parts with grease. Such actions can seriously increase the resource of the tool. But the fact is that the higher the torque, the less the effect of the lubrication and, accordingly, it is necessary to use the best lubrication. The average torque values for different chainsaws range from 8500 rpm to 11-13 thousand for powerful representatives.

Before starting to fill the oil, it is necessary to warm up the chainsaw.

It is also important to evaluate the storage location of the tool. When storing the chainsaw in an unheated room at low temperatures, it must be warmed up before use. Low temperatures adversely affect the operation of mechanisms and the consumption of fuels and lubricants. The crystallization process begins, it dramatically reduces the effectiveness of the lubricant, making the oil less viscous.

When preparing a mixture of oil with fuel, it is necessary to maintain the recommended proportion. It is specified by the manufacturer of the product. As a rule, for old models of domestic brands, they use AI-76 gasoline (which, by the way, is no longer sold very much) with ordinary oil, which is widely used to lubricate motorcycle parts. The proportions are approximately 1:25. Chainsaws of imported and the latest domestic models of chainsaws have increased requirements for the quality of the mixture. Usually it is AI-95 or AI-92 gasoline and branded oils. The recommended proportions are 1:40. For chainsaws with low power you can use almost everything on the market. However, for high-power devices, it is recommended to carefully approach the choice.

First of all, do not forget the fact that during a heavy cycle of work, that is, the operation of the saw at the limit, the oil is consumed no later than 30 minutes. after the start of work, after which you need to pour the additive again. This is typical for almost all devices of this type.

Oil classification

Car oils come in different bases and different compositions.

Basically, the choice of oil directly depends on the operating conditions of the chainsaw. In summer and warm periods, mineral ones show themselves perfectly, in winter and cold periods, synthetics and semi-synthetics will be the best. Moreover, the letter S in the title means specialization for use in the summer. The letter W is for winter. All oils can be classified according to their composition. Distinguish:

Synthetic.
Semi-synthetic.
Mineral.

Some of the synthetic types can be used at temperatures down to minus 40°C. Semi-synthetics are suitable for average temperatures, from about minus 30 ° to plus 20-25 ° C. Some manufacturers use special additives to improve the properties of materials. They change the characteristics of a particular oil. This allows it to be adapted to necessary conditions operation.

Different engines have quite different oil consumption rates. If a 4-stroke engine is used, no residues are generated in the combustion chamber due to its design. In a 2-stroke, for a similar effect, it is necessary to use a separate oil. An important factor to prevent soot residues in the chainsaw is the compatibility of the ingredient used and the fuel.

Consequences that can lead to the use of non-certified oil

Now it’s worth analyzing directly the types of chainsaw chain lubrication. Professionals recommend lubricating the chain only with special oils made by recognized oil manufacturers. This applies to both petrol saws and electric saws. In no case is it allowed to use the so-called "working off" (used machine or motorcycle). The fact is that the gasoline pump, which supplies additional fuel for better job systems, with such use can become clogged and become unusable. This threatens to seriously damage the instrument.

Filtration is sometimes used in an attempt to remove impurities from used oil. This cannot serve as a good lubricant, as the ability to use the chainsaw at high speeds is lost. Poor-quality oil does not allow for sufficient quality of contact between the elements of the saw-tire. Sparks begin to appear and severe wear occurs on the moving parts of the saw. It is also not worth saving, because with a shortage, the circuit starts to heat up very much. When the saw is overheated, the level of edge hardness drops sharply. Such a saw will have to be sharpened more often. And the constant sharpening of the tool can lead to its instant failure at the most inopportune moment.

It is also desirable to use fresh fuels and lubricants, the oil should not be expired. Because it can cause the tool to loop. When storing the chainsaw for a long time, it is recommended to work the tool on high speed until full production combustible mixture. The remains of the mixture in the tool during long-term storage deteriorate and clog the tool. If you do not follow this rule, problems may subsequently arise when using a chainsaw.

It makes sense to have several chains with you.

The chain can fail even if used correctly.

The use of even high-quality oil does not completely eliminate the possibility of a sudden breakdown. And be sure to have oil to top up. Oil consumption in cold or heavy long work may increase sharply. To prevent this during operation, it is recommended to allow the chain to cool and periodically lubricate it.

Chainsaws, as a rule, have a two-stroke or four-stroke engine and two tanks, one of which is filled with fuel, that is, gasoline, and the second should be filled with oil, which lubricates the saw chain. The gasoline tank by volume can include 0.3-1.0 liters of fuel and oil, and the oil tank has a smaller volume, in fact, 2 times.

How is a chainsaw used?

Such a ratio of oil and fuel volumes is used in which the lubricant will be consumed when lubricating the chain at the same time, namely after 30-45 minutes of the time that has been worked out, provided that the chainsaw is fully loaded. If the motor is two-stroke, then it requires the use of a pre-prepared fuel mixture to lubricate the chain to the greatest extent.

The specifics of the operation of the saw is determined by seasonality. When a two-stroke motor is running, its cycle is different from that of a four-stroke tool engine. The use of a mixture of gasoline and oil to lubricate some structural elements chainsaw, such as piston or shaft, is one of the highlights. Otherwise, an attempt associated with the use of a tool that runs on only one gasoline, and not on oil, will not lead to a positive result, but only to damage to the tool.

You can use a domestic tool using 76 brand gasoline simultaneously with oil, the ratio of which to fuel is taken equal to 1/25, that is, in the amount of 4%. If you use a saw model from foreign manufacturers, you will need a brand of gasoline 92 with branded oils.

Chainsaw manufacturers create these oils, while the ratio in the required consistency is 2.5%, 1:40. Two-stroke engines can be installed on foreign-made chainsaws, but it must be taken into account that gasoline is required purified, without impurities.

It is possible to choose oil based on the motor, the number of cycles of which can reach 8.5 thousand / min. In chainsaws from foreign manufacturers, cycles are provided that can reach power in the range from 11 to 14 thousand / min. The use of these lubricants reduces the presence of the motor resource of the saw by 7-10%, which boils down to the following: the use of Zhiguli oils is suitable for all types of household and special chainsaws.

If the tool is used at a low temperature, then even a correctly made choice of lubricant components does not bring the quality of the oil mixed with fuel to a positive result, that is, crystallization and viscosity increase processes occur. With all this, the tool must be adapted to the application, taking into account the maximum engine warm-up.

If you follow the recommendations, then the chainsaw should be warmed up before use, especially if its storage place was a cold room that is not heated. This will prevent a negative result if condensation occurs in the saw mechanism.

What oil is used in a chainsaw?

The life of a chainsaw is determined by the type of lubricant used when working with inventory. A saw with a two-stroke engine and a fuel tank are used in accordance with the instructions. Often, a fuel mixture is made by mixing gasoline and oil, which are combined in a certain ratio. This information must be specified by the manufacturer in the relevant instructions.

If the inventory is domestically produced, then gasoline of the AI-76 brand is usually used, as well as ordinary motorcycle oil. The proportions in which gasoline and oil are taken are 1/25. If chainsaws are used foreign made, then the requirements will be different. They come down to the use of gasoline with an octane rating of 95 and 92, while using a special oil suitable for these brands of fuel.

Oil is mixed with fuel in a ratio of 1/40. Suitable is the use of measuring canisters, which help to greatly simplify the process of manufacturing the fuel mixture. The use of foreign-made tools requires appropriate filling with motorcycle oils.

It should be taken into account that certain types of foreign-made lubricants can be used when working with chainsaws, the cycle of which is 8.5 thousand per minute. Basically, a tool with an oscillation cycle in the range of 11-14 thousand / min is used. The use of foreign oils in such saws is the reason for the reduction in engine life by an average of 8%. If the chainsaw is running on full power, then the lubricant is consumed half an hour after it is turned on.

Experienced professionals recommend using one part of the fuel mixture for two weeks, because otherwise chemical reaction. With all this, oil can lose all its properties, and gasoline is capable of oxidation. As a result, parts are clogged, the motor overheats and the CPG is jammed. The type of oils poured into the tool must be carefully controlled.

What kind of oil to fill in the chainsaw tank correctly?

Diagram of a two-stroke engine.

When lubricating the chain links of the chainsaw, the composition is poured into a special container. Its use helps to reduce the friction force that occurs between the tire and the chain links. The use of special oils with a viscous consistency to lubricate the chainsaw chain will give positive results, provide long term inventory services. In the absence of this substance, car oil is suitable.

Choose suitable oil, allowing high-quality lubrication of the chain, should be depending on the time of the year when it will be used. So, in the summer, mineral oils are best suited, the disadvantage of which is the crystallization of the structure of the substance at low temperatures. Therefore, in winter, experts recommend using oils with special additives that are synthetic, which makes them less viscous. This facilitates the use of the saw at low temperatures, in other words down to -40°C.

The use of semi-synthetics seems to be more suitable option when using a saw at a moderate temperature, fluctuating in the range of -30 - + 25 ° С.

It is categorically not recommended to pour recycled machine oils into the tank to lubricate the chainsaw chain.

Such oils can be highly oxidized, and this is due to the presence of impurities in them, which can cause damage to the chainsaw. However, sometimes when operating saws, they are filled with gear or engine oils, which is acceptable.

Engine oils suitable not only for two-stroke, but also for four-stroke engines are made on the basis of base oil and additional substances, that is, additives that can be different. Various solvents can be used as additives to improve the process of mixing oils and fuels, their pumpability, possible way spraying.

Conditions for the use of oils in chainsaws

Chainsaws operating at high temperatures, can function efficiently due to oils equipped with iron additives. Their main property is to provide lubrication at elevated temperatures.

During this operation of the motor, its running-in is not carried out. The use of a chainsaw with a four-stroke engine with suitable oil, when it is completely burned, is not associated with special requirements.

The choice of oil with a different type of engine for a chainsaw

In order to lubricate the motors of a tool with a two-stroke engine, a burning fuel solution is used, since oil is not used in the fuel composition. If we take into account the differences between the types of oils used in different engines, for example, four-stroke or two-stroke, then there is a difference in the methods of their consumption.

The high-quality operation of a chainsaw with a four-stroke engine is due to the absence of oils in the combustion chamber, because different types motors present different requirements. For example, two-stroke engines are usually filled with oil, the combustion of which does not result in carbon deposits.

A chainsaw with a four-stroke engine can work for a long time as a result of lubrication with oil, which is not subject to special requirements regarding its complete combustion. You can select additives without taking into account the ash content, the level of which should be more than 2%.

If the chainsaw is equipped with a two-stroke engine that runs on oils suitable for four-stroke engines, ash will eventually settle on the walls in the combustion chamber. Ash can remain on the surface of the piston, and an abrasive powder is also formed, which acts on the saw piston like sandpaper.

Erasing of parts of the design of the toolkit is carried out and the period of its use is reduced. The presence of settled soot at the end of the use of oil harms the tool, which can lose its quality of work due to the loss of power from its motor.

If soot is deposited in the exhaust ports, then their cross-sectional area decreases, which is associated with difficulties during the release of exhaust gases and power loss. If ash is deposited on the piston of the cylinder, as well as on its head, then detonation and drip ignition occur. All this leads to a decrease in the power of the saw, which reduces its useful life.

Two types of oil are made for chainsaws, one of which is suitable for creating a fuel mixture. At the same time, brand 92 gasoline is taken in the ratio of 50 parts of gasoline to 1 part of oil (Super 95) used during the operation of a two-stroke engine, respectively. Different manufacturers of chainsaws produce oil for them under different brands, of which there are a sufficient number. So, 5 liters of gasoline are usually mixed with 100 ml of a substance. If you use one that is not suitable for the tool model used, this will lead to damage to the saw and rapid wear.

Unsuitable oil poured into the saw can simply settle in the cylinder on its walls if it entered the combustion chamber, but did not have time to burn out. This approach to the use of a chainsaw leads to a slow reduction in the life of the tool or its trimmer. If the total life of the chainsaw is 400 hours, then this figure can drop to 200 hours.

lubricate saw chain should be filled with special adhesive oil, which must be poured into the saw tank provided for this purpose. After turning on the saw, it is pumped up by a special pump in automatic mode, after which the chain is lubricated.

The chainsaw canister, which includes two containers, can be filled with 6 liters of fuel mixture and 2.5 liters of oil. By changing this ratio, pour in 5 liters of fuel mixture and 3 liters of adhesive oil, the consumption of which will be 1 liter per fuel mixture with a volume of 1.6-2.4 liters.

Recommendations for the use of special oils for chainsaw chains

Lubrication of the saw bar with the chain should be done with a special oil, other types of this substance are not suitable for this purpose. If they are used, the oil pump may fail, as it is equipped with a self-lubricating system for high quality work. To use used, including filtered, oil compounds in a chainsaw means to violate the ability of the tool to high speeds.

The chain requires proper storage, which involves immersing it in oil. If the saw bar is worn out, then do not put a new chain on it. It is important to have a chain in stock, and it is best to purchase several chains at once. The optimal number of chains in stock is 4 pieces, which allows you to work with them in turn and periodically undermine each of them. This ensures a reduced level of wear on each of the components, i.e. bar, chain and drive sprocket.

One intended work with the tool requires the preparation of a certain amount of fuel mixture. However, it is strictly forbidden to work with a chainsaw without oil poured into the tank. When refueling the saw with fuel, you should immediately provide for its required amount, which should be lubricated with a tire with a chain. The main thing is that its composition should be purified, free of impurities, water, sand, debris, etc.

Refueling of tanks should be carried out simultaneously, that is, oil is poured together with a mixture of fuel into different tanks. Air temperature must be taken into account. If the temperature is below -20 ° C, then it must be diluted with dehydrated kerosene, given the ratio of 4: 1, that is, 1 part of kerosene is added to 4 parts. If there is an adjustment for the oil supply, it is made maximum.

Chainsaw owners know very well how to fill in gasoline for a chainsaw. But for those who only buy such equipment and do not know how to use it correctly, you need to know that you cannot just take and pour gasoline into the tank - as a result of such an erroneous action, your chainsaw will fail in a short time. The reason is very simple - for two-stroke engines, which are installed on chainsaws, there is no separate lubrication system. It is necessary to dilute gasoline for chainsaws with engine oil in a special proportion.

Chain saw gasoline engine

Chainsaws, like most other similar equipment, use two-stroke internal combustion engines. Their main advantage over four-stroke engines that are used in cars is the fact that for 2-stroke engines it turns out to remove one and a half times more power with the same volume. But there are also disadvantages - chainsaw oil must be added directly to the fuel tank, which increases oil consumption. As a result, the mixture of oil and gasoline, when burned in the working chamber, turns into an oil mist that settles on the walls of the cylinder and lubricates the elements of the connecting rod and piston group.

Oil for 2-stroke chainsaw engines is diluted in a certain proportion with gasoline and poured into the tank. When the gas in the tank ends, it is necessary to prepare a new mixture. At the same time, it is impossible to use automobile oil in a chainsaw - a special oil is required for two-stroke engines.

What kind of oil to pour into a chainsaw?

It is strictly forbidden to use those oils that are used in automobile engines - you need a special two-stroke chainsaw oil recommended by the manufacturer. Manufacturers themselves do not produce lubricants, with rare exceptions, but cooperate with all well-known brands and often offer their products under their own label. Therefore, in the passport you will definitely find a mention of which 2-stroke chainsaw oil is suitable for this particular model.

TA, TB and TC classification (TSC-1/2/3) according to the American API standard.
2t chainsaw oil of Japanese JASO standard, corresponding to FA, FB and FC classes;
European ISO standard oil, EGB and EGC class.

As for domestic chainsaws, high-quality oil is also recommended for them. If it is not possible to purchase it, then you can use a lubricant designed for 2-stroke motorcycle engines.

What gasoline to fill in a chainsaw?

Manufacturers strongly recommend using only high-quality chainsaw gasoline, with an octane rating of at least 92 and an ethanol content of no more than 10%. It is not recommended to use opaque gasoline that has impurities - they will quickly clog fuel system and engine.

IMPORTANT: it is not necessary to prepare the gasoline mixture for a chainsaw immediately before pouring it into the tank - this can be done in advance. Moreover, many manufacturers produce ready-made containers with several compartments, for example, for gasoline and oil or gasoline, oil and the finished mixture, and also complete such containers with a special measuring syringe. With its help, oil is drawn into the chainsaw in the proportion that is required. But if the mixture is prepared in advance, then its maximum storage period should not exceed 10 days - over time, the octane number of gasoline decreases, and due to the fact that part of the gasoline from the mixture evaporates, the proportion of oil and gasoline for chainsaws changes.

Is it possible to pour 95 gasoline into a chainsaw?

Almost 75% of manufacturers in the chainsaw passport indicate that it is necessary to use AI-92 gasoline. Those owners of such equipment who encounter it for the first time and do not know what kind of gasoline is needed for a chainsaw draw parallels with car engines and conclude that the higher the octane number, the better. As a result, not understanding how to properly dilute gasoline for a chainsaw, they dilute oil and AI-95 gasoline.

The thing is that an increase in the octane number is achieved by introducing various additives into gasoline, as is done in AI-95 and AI-98 gasoline. For two-stroke engines, additives are harmful due to their special design, so you need to use AI-92 gasoline, especially in our country. Firstly, it is correct and will extend the life of the motor, and secondly, it is cheaper. But for some manufacturers, for example for Stihl, AI-95 can also be used, but it is better to take it at good proven gas stations.

How to breed gasoline for a chainsaw?

Before pouring fuel into the tank, it is necessary to prepare the gasoline mixture. The ratio of oil and gasoline for a chainsaw is regulated in strict proportions - as a rule, they are indicated in the instruction manual. In the event that you do not know how much oil to pour into gasoline for a domestic chainsaw, it is recommended to use a ratio of 1:15 - 1:20. That is, for 1 liter of gasoline, use 50-70 ml of oil.

As for imported equipment, here the proportions are completely different. For example, how to dilute gasoline with oil for Husqvarna chainsaws power of 2 kW? To do this, we look at the instructions and see that the manufacturer recommends using a ratio of 1:50, i.e. no more than 20 ml of oil is used per 1 liter of gasoline. If there is no passport (lost, torn, etc.), use the Internet or contact a service center - this way you will find out exactly how much oil you need to fill in gasoline for a chainsaw. An increased amount of oil threatens with increased soot and clogging of the cylinder, which will lead to a break in the piston rings and a decrease in compression, besides, it is expensive. If the amount of chainsaw oil in the mixture is low, this will lead to overheating of the engine and a sharp decrease in its life.

If you don’t know how much oil to pour into a Chinese chainsaw, and you don’t have a passport at hand, then this proportion is approximately 1:25, that is, 40 ml of oil per 1 liter of gasoline. In general, the amount of oil directly depends on the layout - the tighter all the nodes are installed, the less oil is needed.

Before you prepare a gasoline mixture for a chainsaw, you must first pour gasoline into the canister, and only then add oil, not otherwise. Otherwise, the more viscous oil will stick to the walls and bottom of the canister and dissolve worse, which will violate the correct proportions of gasoline and chainsaw oil.

Choosing oil for chainsaw chain lubrication

In addition to the motor, the chainsaw has another important node with many moving parts - a chain. It does not use engine oil, but chainsaw chain oil - it is cheaper and has completely different properties.

Which chainsaw chain oil to use depends on its “age”. If your chainsaw is new and under warranty, you will need to use ONLY branded oils recommended by the manufacturer. Otherwise, if the saw fails, the service center will immediately remove it from the warranty, because. the use of lubricants that do not meet the manufacturer's requirements is a violation of the operating conditions. On the other hand, branded oils are really high quality:

allow to work in a wide temperature range from -30 to +50 C,
high adhesion improves the “sticking” of oil to the chain and reduces its consumption;
additives reduce friction and extend chain life.

If the saw is out of warranty, and buying a branded chainsaw chain oil is not within the budget, any gear or engine oil can be used. It is advisable to change it 2 times a year: in winter, use a thinner oil, in summer - thicker.

What kind of oil to lubricate the chainsaw chain also depends on the wood with which you have to work. For dry wood, gear oil is recommended; for wet wood, it is better to use some kind of diesel engine oil.

The most common circuit problems

How to adjust the oil supply to the chainsaw chain?

If the oil supply to the chain is incorrectly adjusted, the chain may overheat (insufficient supply) or increase oil consumption and oil contamination of the wood (too high supply). Therefore, adjusting the oil supply to the chainsaw chain is a very important process, since both the consumption of the oil itself and the long-term operation of the chainsaw itself depend on it.

How oil is supplied to the chainsaw chain depends on the position of the oil pump plunger adjustment screw. By default, the screw is set in the middle position. To reduce the oil supply, you need to turn it to the "-" mark, to increase it - to the "+" mark.

Why is there no oil flowing to the chainsaw chain?

If the oil does not go to the chainsaw chain at all, then either the oil pump drive itself has failed, or there are problems with air leakage.

Oil pump failure. If, when the oil pump plunger adjustment screw is unscrewed, oil is still not supplied to the chainsaw chain, then the drive, which is a plastic ring with grooves, has broken. Over time, the grooves can wear out, and the drive will fail, after which it will simply have to be replaced.
The hose that supplies pressurized oil to the chain has worn or worn out. You need to re-attach it to the fitting or replace it.
The grooves through which oil is supplied to the chainsaw chain are clogged - this is the most common occurrence. They need to be cleaned, after which the supply will resume.

Why is oil leaking from a chainsaw?

If you notice that oil is leaking from the chainsaw, then this is a malfunction and there may be several reasons for it:

Most often, oil flows from the chainsaw chain if the tightness of the fuel tank is broken. Carefully inspect the tank for cracks or tight fitting of the tube to the fitting. If there are violations, eliminate them.
The oil channels are clogged, as a result of which the oil does not enter them, but drips onto the ground. It is required to clean the channels with pressure - this will fix the problem.
