The chain is not lubricated with oil. Reasons for stopping oil supply to the chainsaw

Eliminate oil leaks on a Chinese chainsaw (photo report)

In some cases, the owners of the chainsaws have to solve more complex problems to fully restore the functionality of their cutting tools.

Chainsaw does not develop full power

In addition to the problem considered above with a lack of admission to the cylinder of gasoline or air, the cause of the weak power may be a clogged muffler.

Carburetor depressurization and nozzle blockage

Over time, the screws fixing the carburetor lid can weaken or gaskets become unusable. A clogged filter or its unskilled replacement can lead to the formation of a blockage of nozzles. All this also negatively affects the work of the chainsaw and reduces the life.

Basil does not hold idle speed

It often happens when, after prolonged transportation and constant use of a chainsaw, he refuses to work evenly at idle. As a rule, this problem is eliminated by the adjustment of the carburetor.

You can find out how to correctly debug the carburetor from this

If the carburetor is rebuilt like a clock, then you must check:

• Fuel system. Start more logical from the fuel pump.
• Muffler. It is likely that due to the abundance of accumulated soot, the engine cannot function normally.

Chainsaw loses power under load

If in the process of work the power of the saw disappears somewhere, then the problem should be sought in the following places:

What kind of oil to fill in the Stihl 180 chainsaw (Stihl 180)

Remember personal safety while working with a chainsaw.

Remember that the quality of the poured oil affects the work of the chainsaw. Advantages of the Husqvarna chainsaw 240 why gasoline from the chainsaw “Husqvarna” 240? Low quality oil can cause the instrument ineffective work and negatively affect its details.

In order for the STIHL MS 180 oil pump to supply oil without difficulty, periodically check and clean the pump. Oil flows from the chainsaw oil leaks. Brief review why oil in a chainsaw. Thus, the process of supply oil will be normal.

During the operation of the chainsaw, two types of problems with the supply of oil to the chain occur:

• Insufficient oil flow that can be caused by various reasons. If you do not take timely measures, the quality of work will worsen significantly, and the chain itself can even become unsuitable for use.
• Excess amount of oil. In this case, after prolonged use, oil pools can accumulate under the saw. This not only affects oil consumption, which must be constantly added, but also has a negative effect on the environment.

Repair of oil supplies of a chainsaw STIHL 180

STIHL MS 180. An indispensable tool for harvesting wood and other wood products. This is one of the most recognizable garden devices armed with functionality.

Note that the semi.professional device for this saw model received an electric ignition and a fairly quick tension of the circuit. Chainsaws. Understand why this flows: why oil flows from under. In addition, the STIHL MS 180 saw has 2 tanks designed for the consistency of gasoline and oil.

One of the main features is a decrease in vibration.

This result is achieved thanks to 4 shock absorbers. It’s no secret that the highest depreciation has a harmful effect on human health and has long been conducted in Europe.

It should be emphasized that without outside help, it is no better to disassemble this saw without special instructions, in this case it is better to entrust the device to the masters.

The owners of this tool model should be prepared for the fact that they may encounter such an unpleasant moment as the flow of oil for lubrication of the chain. It does not follow from the chain, it flows from under the covers. Oil flows from the very beginning. Well, I do not know. Oil can flow when working with equipment and even when it just lies unattended.

A brief overview of why the oil in the chainsaw is ultimately supplied to the tire from the tank. Support our channel as much as possible, it is you.

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant system may differ slightly constructively, but their total number and the connection scheme remain unchanged.

The main components of the lubrication system are:

• Oil tank is usually in the crankcase.
• The filter element is installed in the tank.
• Oil pipe is a small diameter hose made of oil.resistant rubber.
• The heart of the system is an oil pump.
• Worm gear transfers power from the engine to the pump.
• The tire is also a chainsaw, it can also be considered an element of the lubricant system, since it has special openings for oil supply, by the way, the chain itself is involved in the transportation of the oil and, accordingly, also has some elements specially designed to ensure lubrication.

The speed and volume of oil supply to the chain directly depend on the number of revolutions of the star. In some models of chainsaws, a manual adjustment system has a special screw located on the device case. On expensive pollen models, the oil supply is automatically regulated during operation.

Field advice

It is not enough to know how to solve problems with a flying or torn chain, because there is always the opportunity to prevent this. Proper care for the saw will help extend the life of the device and its parts. Therefore, it is recommended to observe the advice of specialists:

• Regularly clean the air filter and lubricate it with oil. Periodically, the filter needs to be changed.
• Each time before starting work, you need to check the reliability of the twist of all nuts and bolts. Then there will be no failures during operation in the device.
• You need to lubricate both bearings and asterisk.
• Regularly clean the candles from fuckers.
• Lubricate, tighten and pull the chain in time.

High.quality chainsaws, provided that the proper care and timely repair can last longer.

When moving the saw chain of the chainsaw in the tire pier, a large amount of heat is released due to friction. If the oil does not enter the chain of the chainsaw, it is necessary to stop the work and take all measures to eliminate the malfunction of the lubricant system. The combination of large loads and overheating of the headset is accompanied by its accelerated wear and early failure.

• All the chainsaws and their electric counterparts are equipped with systems of the same type, through which the lubrication of the tire, saw chain and details of its drive is implemented.
• The standard composition of this device includes a reservoir from which the chain oil is supplied to the input of the pump with fixed or adjustable performance.
• Further, the working fluid in a dosed amount enters the duct of the tire, in which the saw chain with the tails of the saw chain is evenly distributed throughout the headset and the working surface of the crown of the leading star.

Tires of productive sets of 400 mm long are equipped with a driven star. Periodic lubrication of the bearing is carried out individually, after 6-8 hours of production.

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged.

The main components of the details of the lubrication system are:

Oil tank located, as a rule, in the engine crankcase.

How to adjust the oil supply to the chain of the chainsaw. an expert on technology

I start a heading called “Likbez” in which I will talk about the details and nodes of the chainsaws, their design, the reasons for the failure and about the methods of repair.

Open this section of the oil pump. Oil pump in a chainsaw is necessary for lubricating the saw chain during operation. In most cases, a plunger oil pump is installed. Located an oil pump under clutch.

The device of the oil pump of the chainsaw:

To get to it, you need to remove the clutch (the whole process can be seen in detail on the video. Thanks to the author of the video Evgeny Kravchenko for the detailed story!).

This is what the oil pump looks like after filming:

The figure is very clearly visible a plunger in which there is a groove on the tail. This groove is needed to capture the necessary portion of oil and supply it through the hose to the saw tire and further to the chain. Rotation of the plunger is given by an asterisk of the clutch drum. Accordingly, we get the required amount of oil at any engine speed, since the engine speed and the plunger rotation frequency are interconnected.

Many chainsaws have the ability to adjust the amount of oil supplied. The adjustment is carried out by rotating the screw, which reduces or increases the amount of oil captured by the plunger. The screw is located below the pump. (cm.a photo).

Malfunctions of the oil pump and lubrication system:

• The most common reason why the oil lubrication is ceased to be supplied is the output channel clogged. In this case, you just need to blow the channels. The channels can also be clogged on the bus. Just clean it.
• Oil flow during downtime. Several reasons are possible here: 1.Cracks in the oil pump body.2.Check the integrity of the hoses and their fastening.
• Insufficient lubrication of the chain. As I already wrote above, on some chainsaws, it is possible to adjust the amount of oil supplied. If there is no such adjustment, then again several reasons.one. Air leaks through cracks in the hoses, pump housing, or in places of attaching hoses.2.The boots were erased on the oil pump drive. In this case, replacement. This also applies to the plunger.
• Large oil consumption. This malfunction may occur due to: 1.Incorrectly installed tire2.Oil pump output. In fairness, it is worth noting that many chain oil consumption for the lubrication of the chain is great in nature. Reduce its consumption, using specialized oils for lubrication of circuits.

Diagnostics and repair of the oil pump and the lubrication system of the chain of the chainship

Chain lubrication system

Each chainsaw, regardless of its model, brand, and class has approximately the same structure. It consists of several important nodes, among which the lubricant system. Without the latter, the work of a power unit is impossible.

Due to the functioning of the compulsory lubrication system, the tool chain reduces the risk of strong wear, which is guaranteed under the conditions of constant friction of the carved element on the guide tire, inevitable heating.

When lubricating the chain mechanism, friction softens, at the chainsaw operator the need to repair this element or its complete replacement occurs much less often.

What is a compulsory lubricant system?

STIHL chainsaw system and a given node in other power units are an identical node, which depends on the speed and number of roller speeds of the chainsaw, engine. The oil is supplied to the carved element, or rather on the tire, dosed. This is possible due to a special pump.

The chain of the chain lubricant transmits a consumable material with high adhesion characteristics to the saw set. It is necessary only to use the consumable material of this quality, since, only at the maximum speed of the chain mechanism can it be distributed evenly throughout the bus.

The device of the lubricant system

The lubrication system of the chain of the chainship, taking into account the manufacturer, the tools may differ slightly in design features used when creating this unit to details. At the same time, I do not affect the connection diagram of the system, as well as the total number of parts used.

• oil tank placed in the crankcase of the engine;
• tank filter (element, located directly in the tank);
• The oil pipeline that looks like a small hose in diameter made of high.quality rubber;
• The pump itself can be considered the heart of this node;
• Effective from the engine on the heart of the node worm gear (worm transmission).

In some works of specialists in the repair of power units, the guide tire is not simple as a saw set, but as one of the components of the lubricant system. Why is that? This can be explained by the presence of special holes in this bus through which oil is supplied. By the way, the chain itself can be considered a participant in the transportation of lubricants, since this mechanism also has parts associated with the distribution of oil.

By what principle this node works?

The heart of the node is the pump, consider the principle of its functioning.

• As soon as the engine speed increases, the gear of the main shaft using a worm drive makes a pump shaft work.
• When the pump shaft is operating, pressure is created, which is transmitted to the oil line, which pushes the oil towards the bus.
• The end of the lubricant canal is located at the junction of the power unit card and the guide tire, where the longitudinal groove is placed. The latter and there is a lubricant.

What function does the groove perform? It provides oil supply to the guide tire, it doesn’t matter what the tension level has. This is a guarantee that the oil will enter the tire even when it is located in a non.standard position at a working moment.

Do not forget that the chain mechanism takes part in the process of lubrication. Depending on the structural features, the chain has holes or grooves through which the lubricant is distributed along the tire. The oil will enter the tire faster as soon as the engine speeds become higher.

Certain models of the tool have pumps that can be additionally adjusted (the operator will be able to adjust the bandwidth of the pump, depending on the volume of work and operating conditions of the saw). If there is a need, oil supply is reduced, if you need to increase it, the appropriate setting is carried out.

Be sure to read the article where the feature of the oil supply to the chain of the chain of the stihl chain. The system may vary depending on the brand of the chainsaw.

The main plus of such a function is the ability to save consumable. By the way, if you are interested in which oil to lubricate the chain of the chainsaw, choose what is recommended by the manufacturer of your power unit.

Breakage and capable of their elimination

Considering the types of malfunctions of the lubricant, you can highlight two of their categories:

• general breakdowns found in all types of power units;
• individual, which depend on the type of pump, on the features of the transmission of the worm type, on the structural other features of a certain chainsaw.

Important! If the lubricant system does not work, use the saw is not recommended. So you spoil not only the chain, but also the guide tire, as well as the main star, which leads to the need for large investments in the repair of the device.

“Symptoms” of a faulty lubricant:

• The chain mechanism is dry, pale, the shine is absent;
• The chain after installation quickly stretched;
• The guide tire heats up, its paint is paid;
• The oil remains in the previous volume in the tank, despite the intensive use of the tool;
• The effectiveness of the cutting of the backup is significantly reduced.

All this indicates a malfunction of the lubricant or its functioning with interruptions.

If the consumable is received, then the reason for the problematic operation of the lubricant, most likely lies in the clogged filter, which can be cleaned or replaced with a new. If possible, after this manipulation, the supply of consumables is regulated.

If the consumable is not received, then it is necessary to conduct additional diagnostics, since, apparently, the problem is more serious.

Pay attention to the fact that you need to dismantle the tire to check the operation of the lubricant system. Alternatively, the end of the tire is directed to the side (we use chock) from the direction of the cut, maximizing the momentum, hold the tire (its end) 10 centimeters from chock. When supplying oil, you will see the appropriate spots.

What to do if there is no oil supply?

As we have already found out, you need to conduct additional diagnostics. To do this, analyze the lubricant system. Keep in mind that in some models it drank it with a complete disassembly of the tool. So, just in case, arm yourself with appropriate repair tools. If you have no experience of analyzing the saw, trust this business to a professional.

Practical recommendations

Lubrication.

Before starting to operate the chainsaws, you need to check the lubricant system of the chain of the chain of the chain. For this purpose, it is necessary to hold the end of the tire, putting a paper sheet under it. When the speed is added, the oily strip should form on the sheet.

Proper lubrication of the chain greatly increases the duration of the headset of the chainsaw. If the oil is not enough, then the operation of the device will be carried out dry. The cutting headset will quickly break. The friction of the details should be minimal in nature, so all guides, articulated joints should be covered with an oily film.

When the chain moves along the guide tire, the lubrication system should provide a constant flow of oil. This function is performed by the oil pump. With it, the right amount of oil is supplied to the guide tire and its groove.

The leading links of the chain scatter oil to the total length of the groove. A guarantee of proper lubrication of the chain is considered:

Before starting work, it is necessary to constantly monitor the operation of the lubricant system. The correctness of the supply of lubricating material is determined on the sides of the chain, they must be lubricated all the time.

The need for lubricants is always different. It all depends on the fact that it is necessary to cut. When the cut length reaches large values, the tree has high hardness and thick bark, you must have a large supply.

If the cutting headset is smoke or the chain stops, we can talk about a large heating. The main reason is the lack of lubrication. Other reasons can be:

Oil pump device

The first thing that comes to the mind of the holder of a chainsaw, which noticed a malfunction in the operation of an oil.like pump is where to look for this knot? It is located where the drive is, from the same side, right on the crankcase. This part is hidden behind the main asterisk. Its device is easier to disassemble, focusing on the working scheme of a particular model.

So, if, for example, you need to find and fix the oil pump of the Stihl 180 chainsaw, refer to the instructions of this model. In general, of course, the principle of operation of the oil pump is the same, although the knot can look different on each model of the tool.

Principle of operation

The main node of the system is the pump. The principle of its work is as follows. With an increase in engine speed, the gear installed on the main shaft, through the worm gear, the pump shaft drives in motion. In turn, the rotation of the shaft creates a certain pressure in the oil line, which makes the oil move along it towards the tire.

The end of the oil channel is located at the place of contact of the tire with the tool card, where there is a longitudinal groove on which its oil channel gets when installing the tire.

The groove is necessary to ensure the supply of oil to the tire, regardless of the degree of tension of the chain of the chainships. Simply put, no matter what position the tire is at the time of operation, the oil will fall through the groove through the groove.

Then a chain is included in the lubricant process, on the links of which, depending on the model of the circuit, there is either a groove or a hole through which the oil is accelerated over the entire bus. With an increase in engine speed, the oil supply speed also increases.

Some models of the chainsaws are equipped with pumps, which additionally have the adjustment of the bandwidth, and if necessary, the amount of oil supplied by the lubrication system can be increased or reduced.

This function is satisfied with convenient, t. to. allows you to save and not spend excess oil.

List of oils in terms of price and quality

Lubricants for 2-stroke engines:

• Volume 100 ml. you can buy it for 90 r., It is necessary to add 1 to 50 (20 grams of oil per liter of gasoline) to gasoline). This type is designed specifically for Stihl chainsaws. The main component is minerals. It is also possible to use for other models of various manufacturers.
• STIHL (volume 1l) intended for the saw of the manufacturer STIHL. Diluted 1 to 50. The basis of the lubricant is minerals. The price varies within 500 r.
• STIHL with a dispenser (volume 1l). Diluted in a ratio of 1 to 50. The price is about 600 r.
• Stihl h. P. Ultra (volume 100 ml), ratio 1 to 50. Also made for stihl chainsaws. This is synthetic oil. It has a high degree of lubricant advantages. It is also used for other models of chainsaws with 2-stroke engines. The cost of this lubricant varies within 120 r.
• STIHL (volume 5l), the ratio of the product of lubrication to gasoline is 1 to 50. Component. mineral additives. Created directly for the stihl chainsaws with a 2-stroke engine. Apply for others. The price is 1500 r.
• Stihl h. P. ULTRA with a dispenser (volume of 1l), diluted in a proportion of 1 to 50, manufactured for the chainsaw of the manufacturer STIHL. Can be used for other brands. Cost 1100 p.

Oil for lubrication of the chain of chainsaw

Oil for lubrication of the chain of chainsaw

The other day I started my own my own experiment for chains. The main question to which I am looking for an answer: whether a special chain oil is needed in the chain or any lubricant will go there up to work and sunflower oil.

A little theory: what makes the lubricant in the saw chain and what are its tasks? It lubricates the chain and tire. The lubricant should slowly but surely flow through a special channel onto the tire and enter the saw groove, reducing the friction of the chain on the tire. Everything. With a lack of lubrication, local overheating is possible, tire deformation, jamming or breakage of the chain, which is fraught not only with the failure of the saw, but also injuries. With an excess supply of oil, the saw is overgrown with oiled sawdust, and the work is accompanied by the release of a jet of oil per meter or more forward, which is at least inconvenient and unpleasant. A number of saws have an oil supply regulator to the circuit, but basically the oil pump is simply tied to the engine and deprived of adjustments. The saw works. the oil comes. Stopping engine-installation of feed. In such saws (and most of them), increase, increase the oil supply only by changing its viscosity. What are the recommendations of manufacturers? To date, leading manufacturers of the STIHL, Husqvarna, Makita, Bosch and chief manufacturer of the Oregon Founding recommend special, in particular biodegradable chain oils. Special chain oil has improved adhesion (stickiness), is delayed on working surfaces; And the biodegradable, made of plant components (linen, hemp, rape, etc.D.) almost or quite safe for people, soil and green spaces. In addition to special adhesive additives, the composition of chain oils includes anti.sympathetic, outfit and other components that extend the service life of chains and tires. A significant disadvantage of special chain oils is them for a liter and higher and the need to drain the oil unused for a long time or develop it. t.To it can thicken and dry in the system, scoring the supply channels and ruin the inconsistent tool. In the absence of special oils or unwillingness to spend money on them, amateurs and professionals use the entire assortment of oils available at hand: motor of all viscosity, transmission, compressor, etc.D. Along with the proven decades, M8 and M10 are practiced, sunflower oil and any relatively liquid lubricants, which are diluted to the desired consistency with diesel fuel. Extremely and frankly redneck options, as well as exotic experiments with boiling graphite lubrication, I do not consider.

Field advice

It is not enough to know how to solve problems with a flying or torn chain, because there is always the opportunity to prevent this. Proper care for the saw will help extend the life of the device and its parts. Therefore, it is recommended to observe the advice of specialists:

• Regularly clean the air filter and lubricate it with oil. Periodically, the filter needs to be changed.

Features of maintenance and independent repair of chainsaws of the brand Husqvarna (Husqvarna)

Husqvarna chainsaws are indispensable assistants in the household. With the help of gasoline motorized equipment, different works related to construction, logging and simple cutting of branches can be performed. With proper handling of the tool, it will serve for a long time, but during operation as a result of intense loads, different failures occur in work.

If small breakdowns are detected, they do not turn to service centers and workshops, the current repair of the Husqvarna chainsaw is performed independently, while it is necessary to investigate and disassemble the likely causes of defects and ways to eliminate them.

Why not start and what to do

Among the malfunctions of the Husqvarna chainsaw, the engine is highlighted. The motor is either completely impossible to start, or it starts poorly.

When asked why the chainsaw is not started, there is no unequivocal answer. The main assembly unit of the tool is the engine. The stability of the work is influenced by the following conditions:

For each factor, his working knot is responsible:

• for the combustible mixture. carburetor;
• for the air. the cleaning system, in particular, an air filter;
• for a spark. ignition and candle mechanism;
• Lubricant. lubricant and gasoline.

The common reason that the chainsaws are not starting is referring to the non.compliance of the launch algorithm. The motor unit should be launched only after the full assembly of all parts:

The brake of the chain is always turned on. In order not to lose control of the tool, you can not start in the air.

The launch of the motor in the cold state is carried out as follows:

• Put the tool on the ground, step on the back handle with the right foot, the left hand is located on the front handle.
• The saw is in a stable state, the chain does not apply to the soil.
• Take the starter handle with the right hand, pull the cord, while it is not twisted around the hand.
• As soon as the first outbreak occurs, they return the lever of the air damper to the initial position, opening it, and repeat the start.
• Gas and release. The lock is turned off.
• They transfer the engine to idle speed due to the rapid shutdown of the gas limiter.

The launch of a warm engine is carried out in the same sequence, but without opening the damper.

If the start is produced correctly, but the engine does not work, the possible reason is the absence of fuel in the tank, or the fuel chamber of the carburetor is not filled. Check the tank and the camera, fill them with the mixture.

If the incendiary system is faulty, the candle is inspected and checked for the presence of spark on the electrodes. If it is wet (gasoline floods the candle), and the spark is not detected, the part is turned, dried or changed. If it is dry, the spark is present, then the problems in fuel equipment are clogging, depressurization of the gas intake.

Magneto malfunctions are also confirmed by a weak spark. Despite the ignition, there may be no outbreak in the cylinder, while a candle turned out of the cylinder, wet. The method of elimination is the purge of the cylinder with open carburetor shutters.

See “How to make a repair starter with your own hands

The electrodes of the system are covered with soot or oiled. This is eliminated using a metal brush. The candle is washed, cleaned, giving gas to evaporate.

Violation of the gap between the side and central electrodes leads to a poor start. Normal interval indicator-0.6-0.7 mm. It is adjusted by the bending method.

In case of damage to the ceramic insulator surrounding the central candle, or live cores of wires, the wires are replaced.

If it starts and stalls

Husqvarna chainsaw starts and stalls when you press the gas. This leads the jacket of the carburetor jacket and the contamination of the fuel tank filter. The defect is eliminated as follows:

The next reason why the chainsaws stall is pollution of the muffler with exhaust resins. The issue is solved by cleaning.

Distance of piston rings affects the work of the cylinder.piston group. In the presence of a backlash during the audit, the details are replaced.

When starting the engine, the unit may also stall:

• With increased dryness, the channels supplying oil are cleaned, the elements of the connection of the fittings with the tubes are examined;
• When oil leaks in the connecting points or the presence of cracks on the tubes are sealed with sealant.
• If the piston rings in the grooves are buried;
• with the wear and elasticity of the rubber sealing of the crankcase;
• leakage of the cylinder connection to the carder;
• due to improper installation of the ignition force angle;
• as a result of contamination of the ribs of the cylinder and the fan lattress;
• with strong load immediately after buying a new engine.

How to set up a chainsaw

In the process of repairing the Husqvarna chainsaws with their own hands, they reveal some malfunctions that appeared as a result of incorrect ignition adjustments and carburetor settings.

The mechanism is responsible for the power of the motor and is set up for operation, taking into account the necessary conditions:

By default for productive work, the factory settings of the Husqvarna chainsaw carburetor are installed during the tests.

The device has 3 tuned areas:

To configure the chainsaw, after the running.in, they adjust the carburetor: first they are engaged in a “L”, then the screws of XX “T” and “X”. With the rotation of “l” and “x” clockwise the quality of the working mixture “air. fuel” worsens, when rotation against. is enriched. Rotation of the screw “t” clockwise increases the speed of xx.

Repair of the carburetor is carried out by a specialist.

How to dilute gasoline for a Husqvarna chainsaw

For productive operation and increase the service life at high power, they observe the proportion of oil and gasoline for the chainsaw, measuring the measurement of the fuel mixture ingredients with a measured tank. When preparing even a small amount, small inaccuracy affects the quality of fuel.

For dilution, use high.quality gasoline with a minimum octane number. Ron 90. If the parameter is less than the recommended, the engine begins to knock, which leads to its overheating and increasing the load on the bearings. With constant work at high speeds, gasoline with an increased indicator is chosen.

What oils can be used

Leading manufacturers of chainsaws recommend using their own manufacturing materials in their technique. However, often these oils are several times more expensive than simpler from third.party manufacturers.

Pay attention if you doubt the choice of lubrication, then in this case, the best solution would be to purchase lubricants from the manufacturer of equipment.

But what to do if for some reason the purchase of expensive original oil is impossible? Here, the owners of the chainsaws resort to different options. Consider in general terms each of the possible lubricants for saw chains.

Original oils

Often. this is the best choice in terms of operational qualities, but not prices. In addition to optimal lubricants, today manufacturers seek to make these lubricants biodegradable (based on rapeseed bases), which almost does not harm the environment and human health.

STIHL chain oil for the chain of the chainsaw is just referring to biodegradable products. The only significant minus is the price.

Narrow.profile

Special oils for the chain of the chainsaws from third.party manufacturers. Also a good choice. Are much cheaper than branded lubricants, but are often almost not inferior in working qualities.

Cheap industrial oil

The most common option here is the domestic product marked I-20 or I-20A. One of the cheapest options. This industrial oil can be poured into a chain to lubricate the chain and not be afraid of negative consequences.

Lubrication has good properties regarding the conditions of the saw headset and can reliably protect the chain and other elements of the headset from wear.

In terms of working qualities, it loses a little to the original. But the price can be several times lower relative to specialized products. Therefore, this option is used by many owners of chainsaws of any brands and models.

In conditions of heat, it is recommended to control the lubrication level after the production of half the gas tank during the feast.

Due to the very low viscosity, industrial oil is quickly consumed. There are cases when industrial lubricants were produced faster than the fuel tank fell out.

New motor or transmission lubricants

Not entirely justified choice in economic terms. Suitable in cases where the saw is rarely used, and there is no point in buying a canister of a special lubricant separately.

These oils contain a huge number of additives unnecessary and useless to work, which will only pollute the processed lumber and the environment.

Which oil is better to use for a chain video

Here you also need to take into account viscous indicators. The intensity of oil supply to the chain of the chainsaw can decrease greatly with a temperature increase in viscosity.

Thick lubricants in winter conditions can lose their fluidity and ineffectively protect the chain and working surfaces of the tire from wear.

In the case of motor oils during operation in winter, it is recommended to use small options. In general, lubricants for ICE can be used in saws.

Wheelled oils

Use to lubricate the chain of the chainships that have worked out oils is the most unsuccessful idea of ​​all possible.

Firstly, the specifics of the work of the chainsaw implies the creation of oil fog in the production zone, which spreads to the surrounding nature and is partially inhaled by man.

And the development is recognized by carcinogen and is generally extremely toxic. Therefore, in many countries, entire industries have been created for processing the engine and transmission oils that have served their term, and unauthorized drain on the environment is punishable by serious fines.

Secondly, the lubricant quality of working out is extremely low. They are enough with an interference for the average load modes. If you saw a thick log or hard wood of wood. a chain and the rest of the saw set will suffer up to irreversible destruction.

Answering the question of how to replace chain oil for a chainsaw, if you buy the original too much, you can answer this: almost any oil with a suitable viscosity. But not by working out. It is better to pour in a chain lubricant, specially created products for this.

How and when to pour lubrication in a tank? Here the answer is simple: pour it every time when refueling gasoline to a mark on the neck.

We remove the rivets

For separation, efforts will be required: high.quality steel is used for the production of rivets, their shape is geometric.

Fundamentally! A distinctive feature of the inner rivet is a larger radius. Specifically this thickening was created to turn the link, and the role of the outer parts of the rivets is a connecting.

Fundamentally! It is necessary to grind the link from 2 sides, with all this, you should keep from damage to the side parts of the links.

Rivets are knocked out for what purpose use the beard. The side parts in this case are slightly bent.

How to shorten the chain on the chainsaw.

After separation of the part, you should not get rid of a remote rivet. It is possible that replacing her will never be found. It is almost impossible to buy a rivet, but it is quite possible to use it.

Important! When separating the part, it is necessary to count the guides of the ledges on the inside of the chain and the distance between them. There should be a combination between them and the leading star of the chainsaw. Even with a slight deviation in the step of the chainsaws, an extension of such an important part will again occur again
