What oil is suitable for a chainsaw

Husqvarna HP

It is a Swedish manufacturer that includes several well-known brands, including Partner (Partner), known for its semi-professional and professional gardening equipment. Husqvarna produces not only machinery, but also high-quality lubricants used in almost all brands of gasoline-powered tools.

The photo below shows a 2-stroke Husqvarna HP oil, which contains special additives that can compensate for the poor quality of fuel, which is not uncommon in our country. After all, the octane number of gasoline purchased at a gas station does not always correspond to the declared one.

This grease is green and contains a semi-synthetic base. It can be packed both in 10-liter containers and in 1-liter containers. The mixture is diluted in a standard ratio of 1:50 (20 g per 1 liter of gasoline). But when the engine has not yet been run in, or work is coming in the cold, the proportion can be increased to 1:40.

Fuel mixture preparation rules

It is necessary to dilute gasoline with oil in containers that are resistant to the effects of petroleum products (plastic or metal canisters). It is not recommended to use plastic bottles from under water, juice or milk for these purposes, as food grade plastic decomposes under the influence of gasoline. As a result of this process, the fuel mixture will change its properties, and it is difficult to predict what effect it will have on the engine.

The combustible mixture for the chainsaw is easy to prepare.

  • Take the required amount of lubricant and pour it into the prepared container. Do not pour all the prepared gasoline into a container with oil, half of the required amount will be enough.
  • Slightly shaking the container, wait until the lubricant is completely dissolved in gasoline.
  • Now you can fill in the remaining gasoline, mixing it well with the mixture in the container. This completes the preparation of the fuel mixture for the chainsaw.

Before each refueling of the chainsaw, the combustible mixture must be shaken. Also, do not forget to tighten the fuel tank cap well, otherwise this will lead to a lean mixture and engine failure.

It is better to use the ready-made fuel mixture immediately. Therefore, it must be prepared in such an amount that it is enough for the expected volume of work. If, nevertheless, the mixture remains, then it is impossible to store it for more than 1-1.5 months. During this time, it will lose a significant part of its lubricating properties.

Choosing engine oil

An oil intended for a 2-stroke engine must meet the following requirements.

  • The lubricant should form a minimum of ash during combustion. Ideally, it should burn completely.
  • The lubricant must have good solubility in gasoline and a high degree of purification from various impurities that can cause clogging of very narrow channels of the carburetor.
  • The oil must have high anti-corrosion, anti-wear and lubricating properties.

There are certain standards for oils intended for 2-stroke engines: TC-W3 and 2T. A grease complying with the TC-W3 standard is used for water-cooled engines (outboard motors, jet skis). 2T oil is used as an additive in gasoline for 2-stroke air-cooled engines (lawn mowers, mopeds, chainsaws, etc.).

MOTUL Outboard Tech 2T Oil

Oils can be green, red or blue in color. This is done so that their presence in gasoline can be easily determined.

When using poor-quality lubricant, the entire piston group of the engine can fail due to the formation of carbon deposits under the piston rings. As a result, they will not be able to compress, and scuffs will form on the cylinder walls. Also, improper lubrication of the bearings of the crank mechanism leads to overheating and, ultimately, to seizure. Important: it is forbidden to use diesel oil to prepare the fuel mixture, since it does not correspond to any of the above parameters.

Choice of oil for chain lubrication

Remember to check the amount of oil in the oil tank after each refueling of the chainsaw with the fuel mixture. In a chainsaw, an oil pump is responsible for delivering lubricant to the tire on which the saw chain slides. Normally, filling both tanks. fuel and oil. should be done at the same time. Chain oil must be poured into a suitable tank up to the neck. Otherwise, it may run out before fuel, which will lead to overheating of the chain and bus.

Chainsaw chain oil must be designed specifically for this purpose. The use of other lubricants is ineffective and reduces the life of not only the saw, but also the tires of the machine. This is due to the fact that the chain oil contains adhesive additives, due to which the lubricant literally “sticks” to the chain. This property of the oil reduces its consumption, as a result of which the lubrication of the chainsaw bar and the saw chain is improved, and their service life increases.

Also an important parameter of chain lubrication is its density. If you are going to use a lubricant that is not intended for chainsaws, you may notice that oil leaks during operation or after stopping the unit. This fact suggests that the lubricant is too liquid. In addition, the liquid lubricant will quickly scatter in all directions and, accordingly, quickly run out.

When using a chainsaw in winter, you must use oil designed for low temperatures to lubricate the chain, otherwise the oil pump will fail. Therefore, the grease remaining in the tank must be replaced with a low-temperature one.

Leading manufacturers of gas powered tools, such as Stihl, Husqvarna, Makita, Bosch and the manufacturer of accessories for chainsaws Oregon, recommend the use of special highly adhesive oils, including biodegradable ones. But oils of well-known brands have only one drawback. for 1 liter and above. In addition, the grease in the reservoir can thicken over time and clog the channels. For this reason, it has to be drained, and this already increases the consumption. But despite this, we have to admit the fact that only the use of special lubricants can extend the service life of the chainsaw.

What parts of a chainsaw need oil

If you look closely at a working chainsaw, you will immediately notice its main moving part. the saw chain, which slides along the tire during sawing. Since the law of friction still exists, both parts gradually wear out. To slow down this process, it is customary to use chain oil specially formulated to lubricate saw chains.

Chainsaws can be equipped with both four-stroke and two-stroke engines. For 4-stroke units, the crank-connecting rod group is lubricated with oil in the engine crankcase. Two-stroke engines differ slightly in their design and operating principle. Gasoline for this type of drive enters directly into the space under the piston, where the crank mechanism is located, which has several bearings and bushings that need lubrication. Therefore, oil for two-stroke engines of chainsaws is added to gasoline so that it, falling on the rubbing parts of this block, lubricates them.

All about choosing your chainsaw oil

The resource of any chainsaw, no doubt, depends on the quality of its maintenance and operation. The most important requirement for this unit is the timely lubrication of all its moving parts. Chainsaw oil is available in different types, namely, motor and chain oil. The motor is poured into the internal combustion engine, and the chain is intended for the saw chain. Let’s figure out how to choose the right oil for a chainsaw.

Stihl HP Ultra

The oil belongs to the highest category. It is created on a completely synthetic basis, has a green color and has high lubricating properties, and, thanks to salt-free additives, does not create carbon deposits.

The oil was specially developed for the lubrication of engines operating for a long time at high loads and low ambient temperatures, up to 25 ° C. In addition, this lubricant is environmentally friendly. If spilled on the ground, it will decompose by 80% in 21 days. The grease is packaged in bottles of 100 ml and 1 l.

Advantages of automatic systems

Less oil-consuming chainsaws equipped with automatic lubrication systems. Depending on the engine speed, the oil supply is metered by a variable displacement pump.

At idle speed, oil is practically not consumed. Models with automatic lubrication cut material consumption by almost half.

Manufacturers of adhesive oils

Almost all manufacturers of chainsaws are engaged in the production of consumables for them, explaining that these products are most suitable for use in conjunction with their saws. There is no information about how true this is, but based on the experience of operating and repairing chainsaws, it can be noted that there are no significant differences in the service life of parts or at least visible wear.

But the fact is the fact, the manufacturers recommend and cannot be hidden. So, back to the manufacturers, and start with the popular Stihl brand.

Sprocket lubricant

At the end of the chainsaw bar, there is a driven sprocket that rotates the chain. It also needs to be lubricated periodically. For this, thick materials are used. STIHL multipurpose grease can be used. Domestic lithol-based lubricants are also suitable. There is a special hole on the sprocket lubrication tire. You need to pump grease into it with a grease can or a syringe.

It should be noted that with frequent use of the tire toe, for example, when cutting grooves, the load on the sprocket increases and it needs to be lubricated more often.

Major malfunctions and repairs of the chain lubrication system

Consider common malfunctions and repairs of the chain lubrication system of modern chainsaws.

General concept of the chain saw chain lubrication system

To understand how important the choice of chain oil for a chainsaw is, consider the principle of operation of the lubricating mechanism itself using the example of the Stihl 180. This model was chosen as one of the most common modifications of the chainsaw from the Stihl company.

The chain lubrication system of the Stihl 180 chainsaw consists of several main parts:

  • expansion tank;
  • tubes for supplying lubricant from the reservoir to the pump;
  • oil pump;
  • channels for supplying lubricant to the tire (on some saws, the rate of oil pumping into the tire can be adjusted);
  • channel systems inside the bar to distribute the lubricant over the entire working surface of the saw set.

Stihl 180 chainsaw chain lubrication is generally not manually adjustable. It is possible to adjust the oil supply to the chainsaw chain in some other models (for example, on Husqvarna saws).

The oil is poured into a special tank every time you refuel. The designers worked on this chainsaw in such a way that after running out of fuel, a small amount of oil should still remain in the expansion tank. That is, with proper operation, the likelihood that the chainsaw will run dry is excluded.

The lubrication system works as follows. The crankshaft, through a kinematic link, drives a rotary oil pump of the simplest design.

The oil pump creates a vacuum and sucks grease from the reservoir. Then he drives it under pressure into the tire channel system. The oil flows to the driven teeth of the chain and is carried throughout the headset. The chain, the working surface of the bar and its front needle bearing are lubricated.


This brand offers to evaluate a high quality chain lubricant, which has good adhesion and lubrication properties, due to which the lubrication is carried out efficiently, and the chain links and joints are reliably protected from wear. The optimal combination of viscosity and temperature characteristics ensures that this oil can be used in any season and at any temperature.

Divinol offers a variety of chainsaw oils. Which one to use? Zweitaktoel FF attracts attention for its economical consumption, connection with any fuel, prevention of aging of the fuel mixture and excellent protection against corrosion. In addition, this oil can be used at any temperature conditions. Divinol Kettenol and Divinol Kettenol Bio can be used to lubricate chains and bars of chainsaws. With these compounds, links and chain joints can be reliably protected from wear while ensuring economical use of oil. High quality organic oils of this brand provide excellent lubrication and tackiness, so their use is not only easy, but also environmentally friendly.


Despite the abundant supply of oil to the chain, overheating or wedging is still observed. There is only one reason for this. the use of an absolutely unsuitable material for lubrication. This can often be seen when pouring into the mining system.

Chainsaw oil: which one is right?

A chainsaw is a useful and practically irreplaceable tool for every owner. Like any equipment, a chainsaw needs high-quality care. This significantly extends its service life and makes it easier to work with. Chainsaw lubrication is one of the important maintenance items. Today we’ll talk about why you need chainsaw oil and which one is best to use.

Chainsaw oil. why you need it

First, let’s find out which parts of the chainsaw need oil and why.

Most modern chainsaws are equipped with a two-cutter engine. The device of such a motor involves the ingress of gasoline into the space under the piston, there is a crank mechanism, the bearings and bushings of which need additional lubrication. In order for the oil to get into the engine, it is mixed with gasoline and the resulting fuel mixture is refueled with a chainsaw.

The second part of the tool that needs lubrication. this is a saw chain. The chain is the most mobile part of the chainsaw, during operation it continuously slides along the tire, which entails wear of the part.

To increase the service life of the chainsaw, the chain must be often lubricated with special oil.

What kind of oil in a chainsaw to choose?

As it became clear from the previous paragraph, all chainsaw oil can be divided into two groups: motor and chain.

The engine oil used to prepare the fuel mixture must meet the following requirements:

Chainsaw Bar Oil vs Motor Oil

  • maximum combustion. The less carbon deposits remain in the engine during oil production, the better;
  • solubility in gasoline. Only in this case it is possible to obtain a high-quality fuel mixture;
  • no impurities. Various impurities and additives present in the oil can negatively affect the operation of the engine, clog it and lead to damage;
  • good lubricating and anti-corrosion properties. This indicator also directly affects the life of your chainsaw.

Chainsaw engine oil is divided into:

  • mineral. The most common and commonly used. Has an affordable cost;
  • synthetic. expensive and better quality. Synthetic oil for chainsaws does not leave carbon deposits during operation, which significantly extends the life of the device.

What is the best chainsaw oil? This is a natural question.

Of course, according to its characteristics, synthetic will be better, but its price bites. It is important to consider how often and with what intensity you plan to use the instrument. Synthetic motor oil was originally developed for industrial tools. If you do not use your chainsaw often and it works for you for short periods of time, then mineral oil is perfect for you, without harm to the engine. It is also important to consider the fact that if you have been using mineral oil for your chainsaw for a long time, then you cannot switch to synthetic oil. The cleansing properties of synthetic oil will wash away engine deposits and clog.

As for the manufacturer, here it is better to give preference to well-known brands that have proven themselves well on the market. Often manufacturers of chainsaws indicate in the instructions the brand of oil that should be used, in which case it is better to use it. In any case, as long as the tool is under warranty service, because if a breakdown occurs and the service center determines that you used a different chainsaw oil, you may be denied free repair.

Let’s move on to chain oil.

Chainsaw chain oil must be thick, otherwise it will be used up very quickly. Most often, oil for the chain is poured at the same time as refueling the chainsaw, and if its consumption is too high, it may run out earlier than the fuel, and part of the time the chain will spin “dry”.

To avoid this, it is best to use a chain saw oil adhesive. Adhesive particles present in such a lubricant seem to be attracted to the chain and the oil does not fly to the sides when the tool is in operation.

Gear and engine oils are often used to lubricate the chain. They can be used, but in terms of their characteristics they are significantly inferior to adhesive lubricants.

How much oil do you need for a chainsaw

This is the second most popular question.

And in fact, the proportions of the oil are very important. This nuance, as well as the correct oil, affects the operation of your instrument.

It is especially important to observe the proportions when making a fuel mixture for refueling a chainsaw.

READ  Proportions of Oil For Two-Stroke Chainsaw Engines

Before starting work, carefully read the instruction manual for the chainsaw, most often there you can find information on the amount of oil.

If there is no such information in the instructions, then you need to use a ratio of 1:50, that is, for one liter of gasoline you need 20 milliliters of oil. If the chainsaw is used for the first time, then it is permissible to use a ratio of 1:40 for running in the engine.

To prepare the fuel mixture, use a container that will not be damaged by contact with gasoline. Pour gasoline and oil into the container alternately and mix thoroughly. It is not recommended to prepare the mixture in reserve, the ready-made solution can be stored for no more than one month. But experts recommend using it within three days.

Chainsaw chain oil is poured into a special tank right up to the neck. The chain oil must be topped up every time the chainsaw is refueled.

Stihl adhesive oils

The company’s website contains the following adhesive oils designed for various operating temperatures and having a good lubricating performance:

  • ForestPlus adhesive oil. recommended for use at temperatures up to. 15 ° C, shelf life under storage conditions is 3 years. Supplied in 1 liter or 5 liter containers;
  • BioPlus. its peculiarity is a vegetable base, which allows it to decompose quickly when it gets into the soil. It is used up to minus 15, it is supplied in three, five and one liter containers;
  • The latest SynthPlus oil is characterized by its ability to maintain performance at minus 25 ° C.

How to replace the original expensive oil and is it worth?

In situations where it is not possible to use original ones, they can be replaced with oil for car engines. Cheap automobile oils such as autol or diesel lubrication options, due to low adhesion properties, are unsuitable for long-term use.

Some owners, despite the recommendations, still use analogs, preferring to change the tire and chain more often, but here everyone decides for himself. Such oil cannot have any negative effects on the chainsaw lubrication system, which means the difference is only in the quality of the tire protection against chain friction.

Chainsaw chain oil. which one to use

After reading this article, you will fill the knowledge gap, because we will consider the use of oils, of various manufacturers and brands, to reduce friction between the parts of the saw headset. And also we will figure out what additional lubricants are used to service the chainsaw in order to maximize its service life.

Manufacturers of adhesive oils

Almost all manufacturers of chainsaws are engaged in the production of consumables for them, explaining that these products are most suitable for use in conjunction with their saws. There is no information about how true this is, but based on the experience of operating and repairing chainsaws, it can be noted that there are no significant differences in the service life of parts or at least visible wear.

But the fact is the fact, the manufacturers recommend and cannot be hidden. So, back to the manufacturers, and start with the popular Stihl brand.

What oil to use to lubricate the chainsaw chain

The answer to this question is quite simple, for this you need to open the instructions for any saw and it will indicate that you need to fill in oil that has a good adhesion effect.

Adhesion is a measure of the adhesion of a material, in this case oil, to the metal surface of the bar and chain.

What is it for? The fact is that the chain moves along the tire at a high speed, and if oil with low adhesion is used as a lubricant, then most of it, by inertia, flies off the end of the tire and lubrication of its lower part does not occur. This phenomenon can be observed with a small experiment.

Start the chainsaw, point the end of the tire towards a bright surface and add maximum gas. As a result, oil stains will appear on it, which are proof of the theory. Also, we definitely recommend reading an interesting article on how to start a chainsaw.


The company offers its customers Husqvarna Bio Advanced oil for use in normal and extreme conditions. The oil is produced from plant components and is safe for the environment, it is supplied in one liter and five liter containers.

As an economical solution, the company has Vegoil oil, according to the manufacturer, its consumption is reduced by 40% compared to others. Supplied in a liter container.

The company also produces bearing grease, which it recommends for lubricating the bearings of the drive sprocket and the sprocket on the saw bar.

We recommend reading an interesting article about all Husqvarna oils.

You can also get acquainted with some oils for chains by watching the video below, in it a seller of a large network of tools, comments on the use of adhesive oils from various manufacturers.

Chainsaw sprocket lubricant

To increase the service life and reduce friction on the drive sprocket, the manufacturer equips this mechanism with a needle bearing, which must be lubricated periodically. Stihl multipurpose grease can be used for lubrication.

If you do not want to overpay, it is better to use an inexpensive, but no less high-quality option, Litol or Litol 24 grease. Due to its viscosity, Litol will easily replace the original.

It is possible to lubricate the sprocket of the chainsaw tire with the same lubricants as the leading one, using a special filler for this. This allows the lubricant to be pressed in through the technological holes in the tire to the sprocket bearing.

Sprocket lubricant

At the end of the chainsaw bar, there is a driven sprocket that rotates the chain. It also needs to be lubricated periodically. For this, thick materials are used. STIHL multipurpose grease can be used. Domestic lithol-based lubricants are also suitable. There is a special hole on the sprocket lubrication tire. You need to pump grease into it with a grease can or a syringe.

It should be noted that with frequent use of the tire toe, for example, when cutting grooves, the load on the sprocket increases and it needs to be lubricated more often.

How to replace expensive oil

Special branded chain lubricants have the disadvantage of their high price. It is not burdensome to buy a liter of other expensive oil. And if work is coming that requires several liters, or even tens of liters, thoughts of saving will certainly arise. The main thing is not to go to extremes when considering options. You can save on oil to such an extent that you will have to change the chain several times, or even the tire itself or the oil pump.

There are three replacement options. Firstly, specialized products of little-known manufacturers can be used for chain lubrication. But such oils still need to be looked for. In addition, there is a risk of stumbling upon a low-quality product.

Application of oils for automobile engines. They can be used as a temporary replacement, but they cannot boast of high adhesion, so the quality of their work will be clearly worse than special ones. For this reason, it is not recommended to use spindle and diesel oils. the worst in adhesion.

THE BEST 2 CYCLE OIL for use in a chainsaw, and what oil I recommend.

And I must definitely say about one more option. working off. This is the name of the oil that has worked out its life in the engine, and is drained from it when it is replaced.

In fact, this is not an option at all. Metal particles are always present in mining. And if they may not damage the chain itself, then they certainly will not damage the oil pump and the entire lubrication system. On the forums on the Internet, you can find a “killer” argument in favor of working off. that the Soviet Druzhba chainsaw had no chain lubrication at all and worked. So you can pour anything. and so it will do. Well, Stihl will also work with a working off or even with a non-lubricated chain. The question is how long it will work and how many chains will have to be changed during this period.

Caution to those who have a chainsaw within the warranty period. Masters of warranty workshops are able to identify cases of use of low-quality chain lubrication. Especially when using mining. Repairs under warranty will be denied immediately.

Main manufacturers

Leading manufacturers of chainsaws produce consumables and lubricants for them, including those specifically for chains and tires. All other things being equal, you should give preference to the products of the manufacturer of the chainsaw itself. But the quality of the best brands is such that the use of lubricants from another manufacturer will not have a negative impact on the work.

The most famous brands are German STIHL, Swedish Husqvarna and Japanese Makita. They provide a fairly wide range of adhesive oils, including the following:

  • mineral Stihl ForestPlus is designed to work at temperatures up to 15 ℃. Standard packing. 1 and 5 liters. For long-term work, it has recently been produced in a 20-liter container;
  • highly sustainable Stihl BioPlus is plant-based. Once in the soil, it quickly decomposes without contaminating it. The working temperature is also up to 15 ℃. Packing. 1 and 3 liters;
  • semi-synthetic Stihl SynthPlus is suitable for low temperatures, working usable up to 25 °.
  • Eco-friendly, biodegradable Bio and Bio Advanced. It is presented as a universal multigrade oil. Bio Advanced option. improved oxidation resistance and up to 10% better lubricating properties;
  • Makita. Biotop oil;
  • adhesive oil Champion.

Of the Russian brands, especially for chains, there is ZUBR ZMPM-M. There are other, less well-known manufacturers, whose lubricating oil is noticeably lower in price.

Chainsaw chain oil selection rules

All modern chainsaws have a separate oil circuit for lubricating the cutting elements of the chain.

The quality of the saws largely depends on their condition and working conditions. Therefore, companies that produce accessories for chainsaws create special brands of oils that provide reliable surface lubrication.

  • What kind of oil should you use
  • When and how to fill
  • Sprocket lubricant
  • Main manufacturers
  • How to replace expensive oil
  • Oil does not flow to the chain, what are the reasons

What kind of oil should you use

It is widely believed that quality brand-name chainsaw oil should only be used in the engine’s petrol-oil mixture. However, the choice of oil for lubrication is a simple matter. Anyone will do, if only it gets to the right place.

But adding lubricant to the chain is half the battle. It is necessary that it hold on to the metal and remain on the lower edge, with which the tree is sawn. For this purpose, substances with increased adhesion are used, that is, the ability to adhere to the surface and adhere to it. Oil with poor adhesion will fly off the rapidly rotating chain, splattering around uselessly. Of course, some part will remain, but it is not known whether this will be enough so that during intensive work the circuit does not overheat.

Important! During all-season operation with a chainsaw, it is necessary to take into account the dependence of the oil supply conditions on the season and air temperature.

Mineral materials that provide chain and bar lubrication at freezing temperatures crystallize and thicken in the cold. This will cause the lubrication to be difficult to feed and increase the load on the oil pump. Its service life is shortened and it may fail prematurely. In winter, it is necessary to choose synthetic materials with special additives that provide reliable lubrication in frosts down to 40 ℃. At low frosts and temperatures near zero, semi-synthetics are used.

Estimates of the use of different oils for lubricating chainsaw chains boil down to the fact that the wrong choice can increase the engine load by up to 10%. The service life of the chain and guide bar is further reduced.

Due to the fact that in recent years great importance has been attached to ecology, more and more branded oil products are made on the basis of decomposable substances. But during long-term operation, the consumption of chain lubrication can be measured in liters. And for people who are not indifferent to nature, this will be another reason to choose an environmentally friendly product. If you do not care what your site is sprayed with and what marks remain on the wood after cutting.

When and how to fill

Where to fill the chain oil is clear. There is a separate container for this. In most chainsaws, the size of this container is calculated taking into account the volume of the saw’s gas tank. When both tanks are full, they empty at about the same time. Therefore, it is recommended to fill the full volume of the oil tank at the same time as filling the fuel tank. Then you don’t have to be distracted by topping up twice.

Before starting work, it is useful to check if oil will flow to the chain. To do this, simply point the end of the tire onto a flat surface. Some of the grease will fly off the edge of the tire. Droplets on the surface indicate that the system is operating normally.

At high negative temperatures, summer oil thickens and its lubricity deteriorates. Therefore, it is worth using brands designed for winter conditions. If this is not possible, then it is worth taking the time to dilute the existing oil to reduce its thickness. It is best to dilute with kerosene in a ratio of 1 to 4.

Some models have an adjustable feed rate in the lubrication system. It is useful for correcting in the event of a change in grease type.

Note! Do not fill the tank with a mixture of different types of oils. mineral and synthetic.

If the oil from one manufacturer has run out, and the same type is available, but from a different company, then their mixing is allowed, provided that they are used immediately. Leaving such a mixture for a long time is not worth it.

Oil does not flow to the chain, what are the reasons

It is not always during operation that you can immediately see that no oil is supplied to the chainsaw chain. Signs of lack of lubrication:

  • the level in the tank does not drop;
  • cutting is difficult, accompanied by the smell of burnt wood;
  • oil droplets do not fly off the tip of the chainsaw tire.

Having found a malfunction of the oil system, you need to establish its cause. There are few of them. clogging, broken hose or malfunction of the oil pump.

Most often, the oil supply channel is clogged with dirt and sawdust. Air blowing or fine wire cleaning is sufficient to correct the fault. The oil reservoir has its own internal filter. When using normal oil, clogging is unlikely, and when filling, it is quite possible. Have to clean up.

The oil hose may be damaged or completely cut off. You can temporarily seal the damaged area, but it will be safer to replace it with a new one.

And the most serious problem is the breakdown of the oil pump. The reasons may be different. the teeth of the worm gear are worn out, the plunger has jammed, and others. Removing the pump and replacing a damaged part yourself will not be easy. It is safer and easier to contact the service center.
