Stihl No Oil Served On A Chain

Stihl Chainsaw Does Not Lubricate AURAMM.RU Chain

Why not oil arrives on a chainsaw chain?

If in the process of not oil arrives on the chainsaw chain, you need to find the cause of the problem. In fact, the reasons that affect the myth process, you will like a lot. You should disassemble the chainsaw and identify the main problem. The likely premises of this process will be described below.

Due to the lack of oil supply to the circuit during operation of the chainsaw, you will like several reasons for identifying them, you need to disassemble the chainsaw.

Likely prerequisites for non-receipt of fuel

Oil on a chain can not come only in the presence of 2 breakdowns. These include:

tasks with air leaks;
drive breakdown oil pump.

The main characteristics of the chainsaw chain.

The main cause of the breakdown is air leaks. This can happen due to depressurization of the oil hose during operation of the chainsaw. In such circumstances, remove the hose from the hole. This must be done in the area where it is connected to the crankcase. Then the hose sits on the sealant and is installed in its usual position. If this did not help, then elasticity was most likely lost. For the upcoming operation of the chainsaw purposefully change the hose.

2nd reason. drive failure oil pump. In common people, this part is called a worm. When the drive fails, the oil will finish feeding to the circuit. The oil pump drive is a round plastic ring with grooves inside. The constant introduction of the chainsaw leads to the wear of the internal parts, and as a result there is a puncture of the iron hook located inside the drive. After this breakdown, the oil stops flowing to the circuit.

main reasons why not oil arrives stihl 180.

Chainsaw fuel system: 1. fuel filter, 4.5. carburetor, 3. manual preparatory pump.

If the carburetor is correctly adjusted, the fuel will be consumed in an acceptable volume. Otherwise, it will end very rapidly.

Slow reduction of fuel in its operating time Sawing is a common process. If it is absent, the chain is not lubricated correctly, so working with a chainsaw will work well. It is necessary not only to be able to eliminate breakdowns, but also to identify them without the help of others.

Change the flow of fuel there is an option manually. The correctness of the lubrication complex of accounting programs is determined by the method of presenting the tire. If oil splashes appear, it means what remains to be done to our client correctly.

Creating a cut is best with a significant amount of lubricant. If you have to work with soft wood, a small amount of fuel is supplied.

The chain can always be perfectly lubricated. This will avoid smoke and the upcoming failure of the entire chainsaw. If the oil leaks or does not flow at all, you need to identify the cause of the breakdown. Operating the tool before repair is not recommended.

When choosing fuel, you need to do it right. The desire to save leads to the fact that the circuit quickly burns out. To avoid unpleasant consequences, you do not need to choose the oil, the manufacturer of which is China. Preference should be given to unusual firms. According to their own price category, they are significantly higher, but their quality is better.

Resolving Circuit Service Issues

During the operation of the chainsaw you need to constantly look for chain lubrication. Since this part works in the most languid criteria. The chain undergoes constant overheating, dust and abrasive particles get clogged there. This negatively affects its life. To correct the situation allows a special grease. It is fed to the chain from the tank, thereby ensuring unimpeded operation.

If in your operating time no lubrication occurs, the highest possibility of overheating remains. When no oil comes in, the chain begins to stretch. With all this, there remains the possibility of jamming or spontaneous jumping off, and as a result, a person may get severe injury.

The channels through which the fuel is supplied must be clogged with small particles, therefore it is purposeful to clean them from time to time. It is important to watch the oil level in the tank. Debris in the channel becomes a frequent prerequisite for the failure of the chain brake. This can be bad for your work.

Permanent cleaning of the channels and general care of the chainsaw will allow the tool to work for a long time.

However, what to do in this case, if our client is left with tips that are followed, and the oil continues to flow. You need to make sure the chainsaw is working properly. It is entirely possible that it was not properly assembled. If the breakdown was not detected, it is recommended to take it to the workshop. Sometimes it is necessary to change the pump, but this must be done provided that the saw is brand new. Old tools leaking due to deterioration of the tank.

The current state of the chainsaw is able to evaluate only special. In the absence of knowledge or insecurity in one’s own strengths, it is better to entrust a tool repair to a specialist.

DIY carburetor setup for chainsaw

For an independent carburetor option, it is necessary to familiarize yourself with its device and clarify the procedure for the work that is carried out to adjust the parts responsible for the proper functioning of the component parts of the device and parts close to it.

It is necessary to carefully handle objects for the system option, and also determine the compliance of the set characteristics with very acceptable values.

About carburetor design

The carburetor is used to mix a combustible consistency with air, subject to well-established proportions. If clear doses are not respected, the health of the motor is at risk. When a huge amount of air enters during the mixing of the component, and there is not enough fuel, such a mixture is considered "poor."

It should not be allowed and oversaturation, because with a large amount of fuel in comparison with air, malfunctions or deterioration of the motor are also likely. Adjustment A carburetor is needed not only before the initial implementation, but also when any differences in its work are revealed. Before working with a chainsaw, do not forget to run it in.

Carburetor parts

The carburetor design contains a standard set of parts, but may vary little depending on the manufacturer. Components:

The basis. This is a special tube that visually resembles an aerodynamic design. Air passes through it. In the transverse direction, a shutter is located in the middle of the pipe. Her position can be changed. The more it is pushed into the passage, the less air enters the engine.
Diffuser. This is the lent out part of the tube. With its help, the air supply rate increases in the segment where the fuel comes from.
Channels to supply fuel. The fuel mixture is contained in the float chamber, then passes into the nozzle, from which flows into the spray.
Float chamber. It is a separate structural element that resembles the shape of a tank. Designed to constantly maintain an optimal level of fuel fluid before entering the channel from where air comes.

What you need to have to configure

Each carburetor owner must have the necessary tools to adjust this system. There are three adjusting screws that are located on the device. They have their own markings:

L. screw for low speed correction.
H. screw for adjusting high revs.
T. regulates idle move, in most cases it is used for experiments.

Chainsaw Air Filter

Before adjusting the carburetor, you need to prepare the device:

The engine warms up, that is, it starts about 10 minutes before repair, and turns off when work starts (see how to start a chainsaw).
The air filter is checked and flushed.
Is stopping chain by turning the screw T all the way (see butter for the chain).

To carry out safe repairs, you need to prepare a flat surface where you can carefully position the device, and chain turn in the opposite direction. Need a tachometer. It determines the presence of a malfunction in the carburetor. When turning the screws, the sound should be perfect and absolutely even. If screeching notes are noticed, then the mixture is oversaturated.

Setup Instructions

Adjustment carburetor is divided into two main stages. The first is called basic. It is made with the engine turned on. The second is performed when the engine is warm.

To carry out the carb adjustment procedure successfully, you need to familiarize yourself with the instruction manual specific model to identify additional features of the device settings.

First stage

The highest and low rpm adjusting screws should be clockwise until the meeting of the highest resistance. When the screws reach the stop, you need to translate them in the opposite direction and leave when passing 1.5 turns.

Main stage

The engine starts at medium speed and it warms up like this for about 10 minutes. Adjustment screw idle move, must move around clockwise. It is released only when the engine comes into stable operation. It is necessary to control in order to chain during this process did not move.

In mode idle move the engine may stall (the reason is here). In this case, immediately adjust the adjusting screw to clockwise all the way. Sometimes starts to move chain. IN this case twist the adjusting screw in the opposite direction.

Acceleration Test

You need to do a little research. The acceleration of the device is initiated. It is necessary to evaluate the serviceability of the engine during maximum revolutions. When the engine is functioning properly, it means when you click on the accelerator, the speed increases rapidly to 15,000 rpm.

If this does not happen or the speed increase is too slow, you must use the screw marked with the letter L. It turns counterclockwise. It is necessary to observe moderate movements, since the turn cannot be more than 1/8 of the full circle.

Maximum speed

To limit this indicator, use a screw marked H. To increase the speed, turn it clockwise clockwise, and to reduce them in the opposite direction. The maximum frequency must not exceed 15,000 rpm.

If you make this figure more, the engine of the device will run to wear, which will lead to problems in the ignition system. When rotating this screw, the ignition processes of the device must be taken into account. If the slightest glitches appear, then the maximum speed value must be reduced.

Final idle check

Before this procedure, it is necessary to perform a full adjustment of the components of the carburetor when operating at maximum speed. Next, you should check the operation of the device in idle cold mode. When the correct parameters are reached during adjustment, you can see the exact compliance of the carburetor design with the following criteria:

When connecting to idle mode chain does not move.

When even pressing the accelerator a little, the engine accelerates at an accelerated pace. With a gradual increase in pressure, you can notice that the engine speed is proportionally increasing, reaching the maximum allowable values.
When the engine is running, you can compare its sound with a four-stroke device.

If violations are noted in the given parameters or adjustment the device was not implemented in full, you need to perform the main configuration step again. Sometimes actions are performed incorrectly. IN this case the device may fail due to the loss of the correct node settings. IN this case will have to contact a specialist.

Dismantling the carburetor if necessary to check or repair the components

The device of different models of carburetors is almost the same, therefore, when working with them, you can use the standard scheme. All items must be removed carefully and then lay out in the order below, so that you can successfully arrange the objects in place at the end of the repair work.

Top cover removal

The top cover is removed. To do this, unscrew the 3 bolts holding it in a circle.
Foam is also removed, as it is the upper part of the filter that conducts air.
The fuel hose is removed.
The drive rod is displayed immediately on it.
The cable tip is disconnected.
The gas hose can be completely removed by steadily pulling it off the fitting.

To finally prepare the carburetor for a major overhaul or replacement of the smallest parts, you need to carefully disconnect it from the main system. Sometimes it requires further disassembly. Unscrew the components carefully and fold the fasteners in groups, as these small parts are easily lost.

Instruction for chinese

To correctly configure the carburetor of a Chinese chainsaw, you must first remember the factory settings of the device, then turn on the engine. In the future, you will have to leave it to work for several hours to accurately set your own parameters. Sometimes work is performed once after a ten-minute operation of the engine, but many Chinese-made models require special handling.

Chinese model of chainsaw

Adjustment Procedure:

Events start at idle. Using the adjusting screws, you need to achieve a systematic set of revolutions by the engine, so you should first let it work at low speeds. A deviation from the norm is the movement of the chain along the bus. IN this case it is necessary to adjust the extreme screws to the optimal position so that chain remained motionless.
Switching to medium speed revs. Sometimes the engine smokes at the same time. This defect can be eliminated by tightening the screw to supply a leaner fuel mixture.

IN this case smoke will disappear, but engine speed will increase. It is necessary to adjust the settings to the level where, when you press the throttle, the engine gains speed, sharp jerks or interruptions are not heard.

Device engine check in progress. The chainsaw is transferred to the minimum speed, and then a rapid pressing of the lever is carried out. With maximum pressure, it is held for 3 seconds. If there is a malfunction in the engine, you need to gradually loosen the screw until the optimum position is reached.

Chainsaw should work for several hours in real conditions. It is necessary to engage in sawing wood, and then perform an inspection of all the elements involved in this event. If there are deviations, they need to be corrected using adjusting devices. When all defects have been eliminated and optimal settings have been set for the supply of correctly concentrated fuel, the process of setting up the device can be considered completed.

Conclusion

In order for the chainsaw to work properly, it is necessary to carefully carry out work on adjusting the carburetor in exact accordance with their priority. If there are any malfunctions in the operation of the device, you must independently perform its complete disassembly. In most cases, replacement of any parts that have become unusable is required.

With a constant check of the quality of the carburetor settings and the implementation of timely actions to improve its operation, there are no problems with the chainsaw.

Oil Does Not Go To Stihl 180 Chain AURAMM.RU

The Stihl chainsaw is called the smallest and having a fairly huge power. You can do various operations with wood species. This model is a more necessary device, because it has a good cutting ability. The tool has a huge number of additional accessories that add convenience when working.

Schematic diagram of the Stihl chainsaw.

The Stihl chainsaw chain lubrication system consists of:

guide rail;
saw chain;
oil pump.

The oil supply by the pump has a special adjustment. Lubrication of the chainsaw chain occurs continuously during operation of the machine. Because chainsaw chains have a long operating time.

At the time of operation, the chain asks for a constant supply of lubricant. It must be provided with a continuous feed. This is requested by the design of the device. At the time of operation of the chainsaw, the oil leaves the groove of the tire, is simultaneously absorbed by sawdust.

Therefore, the chain is lubricated in automatic mode. Some chainsaw chains are equipped with a system that regulates a clear amount of lubricant supplied. The cheapest devices are equipped with a hand pump that runs on a drive located on the handle.

Scheme of work verification allowing accounting (software) of chain lubrication.

For good chain lubrication, a special oil was specially created. After work, it quickly decomposes, there is no violation of the environmental allowing accounting (software). You can use brand oils:

Transmission grease is completely unsuitable at work. In the cold season, it freezes, the oil system clogs up during the season, you have to completely clean it.

In winter, chain lubrication requires special attention. Branded oil "M-20" with severe frost thickens and resembles petroleum jelly. To work in the winter months, you need to lubricate chainsaws with special winter oil, which has a more watery consistency.

It is not often possible to purchase such a lubricant. To solve the problem, diesel fuel is combined with oil, the viscosity decreases. But if the previously filled oil remained in the crankcase, then the addition of diluted oil will not give a useful effect, the channels of the accounting system will remain clogged. There is only one way out. heating the chainsaw in a warm room.

If there is not much hardening of the chain oil, of course, test melt it by starting the saw at low idle.

Chainsaws are a popular tool for those people who have to do countless chores without the help of others. They are used for various purposes. to harvest firewood, cut dry branches. Alas, the device will serve.

Stihl company produces not only chainsaws and lawn mowers, but also supplies to them. Here we will talk about Stihl saw chains, their types, labeling, properties, comparable with rivals. What remains to do for our client Stihl chains have.

Chainsaw chain lubrication systemOne of the important chainsaw systems, working without busy is not possible is the system of forced lubrication of a chainsaw chain. Everyone knows that at the time of the saw’s operation, the chain friction on the chainsaw tire occurs, which causes it to heat up.

The layout of the holes for lubrication.

Before you start operating chainsaws, it is necessary to check the lubrication allowing the accounting (software) chains of chainsaws. To this end, you need to hold the end of the tire, placing a cardboard sheet under it. When revolutions are added, an oily strip should form on the sheet.

Proper chain lubrication greatly extends the life of the chainsaw headset. If there is not enough oil, then the device is dry. The cutting headset will break rapidly. Friction of parts must have a small temper, because our client remains guides, swivel joints are necessary covered with an oily film.

When the chain moves along the guide rail, the lubrication system must provide a constant flow of oil. This function is done by the oil pump. Thanks to its use, the required amount of oil is fed into the guide rail and its groove.

Leading links of the chain spread the oil over the total length of the groove. The guarantee of the right
chain lubrication is considered:

precise setting of the oil pump;
completely filled oil tank;
the right choice of oil.

While getting started, you need to constantly keep under control the work that allows you to maintain accounting (software) lubrication. The correctness of the supply of lubricant is determined by the edges of the chain, it is always necessary to be lubricated.

The main characteristics of the chainsaw chain.

The need for lubricants is always different. It all depends on the correct selection of the studio, what needs to be sawn. When the length of the cut reaches huge values, the tree has the highest hardness and thick bark, you need to have a large supply of oil.

If the cutting headset is smoked, in other words, the chain stops, you can say that there is a lot of heat. The main premise is a lack of lubrication. Other eyes include:

dull chain;
strong tension.

To repair a chainsaw, you need to get involved in its internal device, the operation of all devices, to study the lubricant supply system. When the chainsaw works, subsequent difficulties arise.

Often there is a leak of oil water.

Hose tightness may be impaired. To solve this problem, it is necessary to disassemble the tool, to change the hoses. If there are no spare parts, there is an option to degrease an old hose and its seat. Fit self-tightening clamps to the hose connection with the tube. The field of this density will be restored.

When the oil filter is clogged. It must be cleaned at times. Oil supply is repaired exclusively in case of a dry chain. Typically, this is due to clogged channels. They need to be thoroughly cleaned. This phenomenon is quite common.

When it is difficult to start a chainsaw, and sometimes it is simply impossible, it is necessary to diagnose the device. At first, the candles and the air filter are checked. Before re-installation, our customer is left with the parts that need to be perfectly dried.

Chainsaw fuel system: 1. fuel filter, 3.2. carburetor, 3. manual preparatory pump.

If there is fuel on the candles, of course say about its surplus. The main prerequisite for such an obstacle is a bad carb adjustment or improper start. To you, the fuel supply valve is closed. To remove the breakdown, you need to make sure that there is enough fuel in the gas tank, check how well the combustion chamber works. If the candles become unusable, they need to be replaced.

Video: Stihl No Oil Served On A Chain

Maybe the fuel supply is over due to a clogged breather. A vacuum appears in the gas tank, which shuts off the fuel supply. This phenomenon appears when the channels are clogged, the carburetor is badly tuned and the air filter is clogged. These problems require repair of the valve, which smooths the pressure at the time of gasoline supply. The breather is cleaned with a sharp needle.

To adjust the carburetor, it is necessary to find the best value of revolutions. For this purpose, you need to twist or, conversely, unscrew the adjusting screws. Such a setting should be made exactly according to the annotation of the repair of the Stihl chainsaw.

The filter mesh is cleaned in the carburetor, channels are blown to our customer, the membrane is checked for operability, and no breaks are allowed.

Work with the carburetor due to its complex mechanism must be carried out carefully and in impeccable cleanliness. This affects his normal and not bad work.

To achieve the proper operation of the chainsaw, you need to take care of it constantly. She asks for constant cleaning of the air filter, lubrication of the chain, while certainly new, fresh oil.

When the tool is put away for long-term storage, all gasoline must be drained and oil removed to lubricate the chain. In this case, the chainsaw works without breakdowns for a long period.

Often the owners of such chainsaws are wondering which oil is used for the saw. Her work may be affected by:

cutting headset;
climate;
wood species.

To solve this problem, a universal semi-synthetic oil was created at Stihl. It is suitable for all high-speed chainsaws. Be sure to use such an oil to lubricate the chain. The tool works flawlessly.

Because Stihl semi-synthetics are created for chains, it is made from special high-quality materials, does not have in its composition various toxic substances that cause cancer. The oil fully meets the most serious environmental requirements.

The Russian climate is quite cruel. In our state there are areas where frosts often overcome the values at 20 ° С. The latest Stihl chainsaw oil has been specially created to perform work in cool conditions. In such a frost, it shows better fluidity.

Special additives included in the oil do not allow the greasing of the cutting set, they will extend the life of other lubricated parts. A saw with such oil simply starts even after a long storage.

The use of such a chain lubricant reduces wear on the saw chain. Due to the high oil endurance at the highest temperature, the cutting headset is perfectly protected. This oil is not afraid of a peak temperature load. In fact, smoke never occurs.

Poor oil supply to the Stihl 180 chain. Stihl chainsaw does not lubricate the chain

One of the important chainsaw systems, work without which is impossible, is the system of forced lubrication of the chainsaw chains. It’s no secret that at the time of the saw’s operation, the chain abrases on the chainsaw tire, which causes it to heat up and premature wear. To mitigate friction, the chain mechanism must be constantly lubricated.

To supply oil to lubricate the chainsaw chains, a special pump is used in the tool, which is dosed, depending on the number of engine revolutions, supplies lubricant to the saw bar.

The system uses oil to lubricate the chainsaw chain, which has improved adhesion properties, this is necessary for uniform distribution of oil around the entire perimeter of the tire and hold on it even at high speeds of chain rotation. Let us consider in more detail the oil supply system implemented in modern chainsaws.

Lubrication system device

Depending on the brand of the chainsaw, the details of the lubrication system may vary slightly constructively, but their total number and connection diagram remains unchanged.

The main components of a lubrication system are:

Principle of operation

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

The end of the oil channel is located at the place where the tire contacts the tool case, where there is a longitudinal groove onto which the oil channel enters when the tire is installed.

Grooving is necessary to ensure that oil is supplied to the tire, regardless of the degree of chain tension of the chainsaw. Simply put, no matter what position the tire is at the time of operation, oil will flow through the groove through it.

Further, a chain is included in the lubrication process, on the links of which, depending on the model of the chain, there is either a groove or a hole through which the oil is dispersed throughout the tire. With an increase in engine speed, the oil feed rate also increases.

Some chainsaw models are equipped with pumps that additionally have a capacity control, and if necessary, the amount of oil supplied by the lubrication system can be increased or decreased.

This function is quite convenient, because it allows you to save and not to waste extra oil.

Lubrication system malfunctions and how they are eliminated

The main malfunctions of the oil supply system on a chainsaw can be divided into two main types, these are general malfunctions inherent in all chainsaws and individual ones, which can vary depending on the type of pump and worm gear installed on a particular model. Let’s start sorting out the faults in order.

Working with a chainsaw if the chain is not lubricated is prohibited. This adversely affects the tire, the drive sprocket and the chain, and can also result in serious repair costs.

Signs of a malfunction of the lubrication system, checking its performance

The chain of the chainsaw is dry and has a pale shade without shine.
The chain stretches relatively quickly.
The tire is very hot and may even partially melt the paint.
Oil from the tank is practically not reduced.
Sharp chain cut efficiency

All these signs indicate that the lubrication process is abnormal. In order to check the oil supply by the lubrication system, it is necessary to remove the side tire of the chainsaw and start it. Next, you need to slightly increase the speed while observing the end of the oil line. If oil comes in, most likely its quantity is not enough for normal lubrication and you need to clean or replace the filter and, if possible, adjust the flow. In the case when it does not arrive, the problem is more serious and requires further diagnosis.

There is a way to check the oil supply without removing the tire. To do this, it is necessary to direct the end of the tire to the side, for example, of freshly sawn chocks from the cut side and maximize the speed, while you should try to keep the end of the tire at a distance of no more than 10 cm from the chocks. If oily stains begin to appear on its surface. then the oil is supplied.

Troubleshooting

Once it has been determined that no oil is being supplied, further diagnostics are only possible if the oil system is completely removed. Of course, filter replacement helps in some situations, but this is very rare.

Access to the oil pump of some models of saws is possible only after complete disassembly, respectively, having no skills in repairing gas tools, it is better to entrust the repair to professionals.

Most common malfunctions

Stihl MS 180 individual lubrication system malfunction

Due to the fact that the Stihl MS 180 is one of the most common chainsaw models, I want to dwell on one malfunction inherent only to it and describe a way to eliminate it without replacing parts.

Quite often on a Stihl MS 180 chainsaw, there is a depressurization of the oil line in the place where the oil pipe coming from the tank is installed in the saw body. The malfunction can be determined by the characteristic smudges on the bottom of the tool.

To eliminate the malfunction, it is necessary to remove the chainsaw handle, remove the hose from the bore hole, clean and degrease it. After all these manipulations, apply sealant to the hose seat and install in the chainsaw body.

You can learn more about troubleshooting and a complete diagnosis of the Stihl chainsaw lubrication system by watching the video, which shows step by step the process of disassembling and repairing the lubrication system.

Conclusion

In modern chainsaws, a reliable supply of lubricant for the chain is organized, in case of malfunctions of which, it is not worth operating the chainsaw in order to avoid further breakdowns. It is better to troubleshoot the lubrication system by contacting a service center or a specialist with repair experience, this ensures the quality of the final result.

If no oil enters the chainsaw during operation, look for the cause of the problem. In fact, there can be many factors influencing this process. You should disassemble the chainsaw and identify the main problem. Possible reasons for this process will be described below.

The reason for the lack of oil supply to the circuit during the operation of the chainsaw may be several factors and to identify them, it is necessary to disassemble the chainsaw.

Possible causes of non-receipt of fuel

Oil may not flow onto the circuit only if there are two breakdowns. These include:

problems with air leaks;
damage to the oil pump drive.

The main cause of the breakdown is air leaks. This can happen due to depressurization of the oil hose in the process of using a chainsaw. In this case, remove the hose from the hole. Do this in the place where it is connected to the crankcase. Then the hose sits on the sealant and installs in the usual position. If this did not help, then elasticity was most likely lost. For further operation of the chainsaw, it is advisable to replace the hose.

The second reason is the failure of the oil pump drive. In common people, this part is called a worm. When the drive fails, the oil will no longer flow to the circuit. The oil pump drive is a round plastic

Non Lubricated Stihl 180 Chainsaw Chain

Not oil arrives on the chain Chainsaws: Prerequisites and Solutions

When moving the chainsaw chains in the groove of the tire due to friction, a huge amount of heat is generated. If not oil arrives on the chain chainsaws, you need to suspend the work and take all measures to eliminate the malfunction of the lubrication system. The combination of huge loads and overheating of the headset is accompanied by its accelerated wear and premature failure.

Without exception, all chainsaws and their electronic counterparts are equipped with the same type of action systems, by means of which lubrication of the tire, the saw chain and its drive parts is realized.
A tank is included in the standard composition of this device, from which the chain oil is supplied to the pump inlet with a fixed or adjustable capacity.
Next, the working fluid in a metered amount enters the groove of the tire, in which the shanks of the saw chain are moderately distributed throughout the headset and the working surface of the crown of the drive sprocket.

Tires for product sets over 400 mm are equipped with a driven sprocket. Repeated bearing lubrication is done personally, after 6-8 hours of production.

Symptoms of a lubricant system malfunction

The right choice of consumable lubricant and the perfect operation of the system contribute to true lubrication, efficient cooling of the saw equipment and the full development of its resource.

There are several external signs that the chain on the chainsaw is not lubricated. First of all, it is:

constant oil level in the tank;
increased load on the engine;
accelerated wear of the cutting edges of the saw links;
the corresponding smell of overheated wood.

In the most ordinary variant, a prerequisite for oil starvation may be clogging of oil-conducting channels with sawdust. This defect is typical for economical headsets that do not have comfortable access to problem areas.

The cost of such systems is offset by an economical, up to 50%, flow rate of the working fluid.

Self-help troubleshooting feature

A full-fledged independent repair of the chainsaw chain lubricant, all conditions being equal, requires knowledge of the interaction of all elements of the system, the availability of tools and locksmith skills.

The restoration of the operating parameters of many chainsaws provides for partial or complete dismantling of the component equipment. To perform complex repair work it is better to use the capabilities and technical potential of service workshops.

Parts with torn threads and damaged splined joints, as well as non-separable structures that complete the lubrication system of popular chainsaws Stihl 180 and other similar models are subject to replacement.

If, when the tank is filled, oil does not enter the headset design, the reason should be sought in the pump itself. Dismantling and disassembling the mechanism will help to identify defective parts and eliminate the malfunction by replacing them.

Checking the system for oil output and performance

Oil filter contamination results in a significant decrease in pump performance. Checking this option is easy. To do this, you need to hold the headset of the working revolving saw over a clean sheet of paper.

By the density and size of the oil strip, you can confidently judge the condition of the system and the complexity of the upcoming repair.

When asked why the repaired lubrication system works, but the oil does not go chain in the right amount. there is no single answer. The cause of failure may be mistakes made during assembly, malfunctioning of standard adjustments, inconsistency of the density and viscosity of the selected composition with the declared characteristics.

Headset oil starvation is possible when installing on a household saw with an uncontrolled pump a longer production tire, which is equipped with professional-grade chainsaw equipment.

The specifics of repairing Chinese chainsaws

A significant share of the imported chainsaw range is made up of Chinese-made chainsaw equipment. Many models with more or less success are copied from the best European developments.

The main advantage of Chinese products of the budget segment is a high level of interchangeability of spare parts, components and systems. For the repair of Chinese chainsaws, in some cases, you can use accessories from models of other manufacturers identical in power and purpose.

Stihl 180 does not go oil on the chain

Chainsaw Chain Lubrication System

To supply oil to lubricate the chainsaw chains, a special pump is used in the tool, which is dosed, depending on the number of engine revolutions, supplies lubricant to the saw bar.

Lubrication system device

Depending on the brand of the chainsaw, the details of the lubrication system may vary slightly constructively, but their total number and connection diagram remains unchanged.

The main components of a lubrication system are:

An oil tank is usually located in the crankcase.
The filter element is installed in the tank.
The oil pipe is a small diameter hose made of oil resistant rubber.
The heart of the system is the oil pump.
Worm gear gear transmitting force from the engine to the pump.
Chainsaw tire, it can also be considered an element of the lubrication system, as it has special holes for oil supply, by the way, the chain itself is involved in the transportation of oil and accordingly also has some elements designed specifically to provide lubrication.

Principle of operation

The end of the oil channel is located at the place where the tire contacts the tool case, where there is a longitudinal groove onto which the oil channel enters when the tire is installed.

Some chainsaw models are equipped with pumps that additionally have a capacity control, and if necessary, the amount of oil supplied by the lubrication system can be increased or decreased.

This function is quite convenient, because it allows you to save and not to waste extra oil.

Lubrication system malfunctions and how they are eliminated

Working with a chainsaw if the chain is not lubricated is prohibited. This adversely affects the tire, the drive sprocket and the chain, and can also result in serious repair costs.

Signs of a malfunction of the lubrication system, checking its performance

The chain of the chainsaw is dry and has a pale shade without shine.
The chain stretches relatively quickly.
The tire is very hot and may even partially melt the paint.
Oil from the tank is practically not reduced.
Sharp chain cut efficiency

Troubleshooting

Access to the oil pump of some models of saws is possible only after complete disassembly, respectively, having no skills in repairing gas tools, it is better to entrust the repair to professionals.

Most common malfunctions

Breakage of an oil hose. It can sometimes be found during visual inspection. The problem is solved by replacing the defective part.
Lack of thread on the shaft of the oil pump will help replace it.
A defective thread on the pump drive gear is likewise solved by installing a new part.
No corkscrew of the main shaft (relevant for some models of tools, for example, Homelite). You can fix it by installing a corkscrew that is suitable for the diameter of cloves instead of the native corkscrew, cutting it to the required length.
Blockage in the highway. It can be removed by blowing with compressed air or mechanically, using a wire of suitable diameter.
Clogged filter element.
The Stihl MS 180, whose pump is not separable, often clogs. You can try to rinse in clean gasoline if it does not help replace it.
In Chinese chainsaws (Gypsy), very often cuts the grooves on the main gear, through which the force from the sprocket is transmitted to it.

Stihl MS 180 individual lubrication system malfunction

Due to the fact that the Stihl MS 180 is one of the most common chainsaw models, I want to dwell on one malfunction inherent only to it and describe a way to eliminate it without replacing parts.

Conclusion

I want to apply it to the TAD 17 chain on a Stihl 250 chainsaw. In winter it is very thick, will the oil pump be worse from this, will it fail from overload? And if it’s possible, what’s the principle, in the pump, of supplying oil to the circuit?

The oil pump, which is set at 180. 250 Styles. is generally practically indestructible. it has a brass cylinder. Even mining consumes twice as long as aluminum.

And the principle of operation is very simple. It’s a pity there is no illustration, and I haven’t seen it anywhere. If in words. two parts, a cylinder and a plunger rotating in it. The plunger has a milled scaffold at the end. During rotation, the plunger moves slightly back and forth.

Two holes are made in the cylinder against each other. When the flat of the plunger approaches the intake hole, it is slightly pulled out of the cylinder. a vacuum is created and a little oil is sucked.

when the flat turns to the discharge hole, the plunger moves into the cylinder. pressure is created, oil goes through the channel to the tire. As you can see, in principle, you can’t damage the pump as much as you like with thick oil. it just won’t go and that’s it.
_

If the oil flows out of the tank in chainsaw idle mode. is this normal? Those. if you have to cut a little bit, then pour a little bit? And then during the inactivity of the saw, oil from the tank flows completely.

No. It is not normal. The problem is either with the oil pump or with the tank itself. In general, oil and fuel consumption is usually 1 to 1.

Leading tire sprocket on a chainsaw, how to lubricate? Is Mobil or Jcb hydraulic grease suitable, for example? What do you think?

stars on all tires (except Calm) are smeared, if you don’t smear, the bearing may crumble, and then the tire ends, and about Calm tires. on the one hand, it’s like a plus, and on the other. I saw Calm almost new tires with burned bearings.
_

A chainsaw drives a chain lubrication oil. At idle it pours very slowly, you give gas. it pours. In five minutes, all the oil is poured.

Does not respond to the position of the adjusting screw. Also, a little (0.5-1 mm), the sprocket, which rotates the chain, plays. Who faced such a thing?

You need to remove the asterisk and sort out the oil pump, and check the hoses for gusts. The drive sprocket must have a slight play. It should not be hard, vibration will go to the crankshaft.
_

The holes coincide when I put it, maybe when pulling up the chain, the hole moves away because oil does not get on the chain, but the chains can be used alone, how to blunt, remove, put in a new one, the old one to sharpen, etc. do so far in a cycle of three chains the tire did not run off?

The oval hole for lubrication on the chainsaw body is made in such a way that at any position of the tire within the range of adjustment by the chain tensioner, the combination of the lubrication holes on the tire and the body does not disappear.

Ideally, a set of chains, when using them on a saw in turn in a cyclic mode, and the bus should become unusable at the same time. There are two lubrication options. Well, in the sense. through which oil is supplied.

Most tires have a separate hole for lubricating the chain, and these large ones are used for tensioning. And some (and quite a few) do not have a separate lubrication hole.

And for lubrication, a free tension hole is used. In this case, it will certainly communicate with the groove of the tire. You can check the wire. This is neither good nor bad, it is a feature.

So. in the second case, quite large oil losses are possible if the sprocket cover does not fit snugly. Then it goes just right through (unlike tires with a separate hole), and drips down.
_

After a minute of idling the chainsaw, I pressed the gas a little several times on the gas to lubricate the chain, it began to flow very strongly onto the chain, which already formed a pool of oil under the saw. Where is the screw for adjusting the oil supply to the circuit? And how to make this adjustment?

Your model does not have an oil flow adjustment to the circuit; oil is automatically supplied. Carefully inspect and thoroughly clean the oil intake holes on the tire, carefully install the tire with a chain. In theory, it should help.

If a puddle of oil forms under the saw, then the most probable is a loose tire or a clutch cover that is skewed, resulting in a gap between the oil pump outlet and the tire lubrication hole, into which the oil escapes.

Tell us more about the oil pumps installed in chainsaws.

Very rarely on modern chain saws (including electric ones) non-plunger pumps are used. It can be said that they are not even applied at all. All of them work according to the same scheme.

The main details are an aluminum cylinder, rigidly fixed in the body and a steel plunger with a plastic gear, rotating in this cylinder. How it works: There is one small hole at the blind end of the cylinder. There is one more opposite.

One of them is suction, the second is pressure. On the plastic gear of the plunger there is an oblique annular groove, which is combined with a metal rod in the housing.

Mechanics: When the plunger rotates due to the oblique groove, it also makes back and forth movements back and forth for each revolution.

Hydraulics: When the cut portion of the end of the plunger approaches the suction port, the plunger is pulled back. a small vacuum is created, a portion of the oil is sucked into the cylinder.

Turning the plunger about half a turn. the cut-off section (of course, with the oil in it) fits the discharge hole.

At this time, the plunger moves towards the blind end of the cylinder. Some pressure is created, the oil enters the lubrication channel.

Now, about the differences in design: The gear on the plunger can be metal. In this case, the worm on the crankshaft will be plastic, you can’t get anywhere, it should be
weakness.

The pump housing may be metal. Well, not bad, of course, but not fundamentally.
And most importantly. the adjustment of the oil supply. In the first case, when the axial movement of the plunger is carried out by an oblique annular groove.

Performance adjustment is not technically possible. If the longitudinal movement is due to an oblique cut of the back of the plunger, flow adjustment is possible.

Using different variants of the adjustable stop of the rear part of the plunger, the length of its axial movement and, accordingly, the amount of oil captured per revolution of the plunger are changed.

how often do you need to syringe a chainsaw tire? And as I understand it, the lubricant should be consistent, like lithol approximately? Or is the same transmission permissible?

I bought a new chain, installed, it works fine. But after a couple of minutes, the hole in the tire for oil supply is blocked, and the chain goes dry.

Literally enough for one cut. Again, disassemble, clean, run. Without sawing, the chain is lubricated. And after one cut, the tire is again clogged with chips.

I didn’t try Gazanut, because I didn’t have time, the chain almost wedges, I can’t turn it by hand, and the tire and chain are terribly hot, the chainsaw stalls. Tell me what the problem is, with the old chain this was not observed?

There is a big suspicion that the lubricating oil is actually going on, only because of the large amount of dust (perhaps now saw dry wood, or even with dust) falling into the groove of the tire and it is not visible on the chain.

What is the condition of the tire itself? In this case, the state of the driven sprocket and tire spacers (the chain slides during operation) is especially important in those places where the teeth of the sprocket “dive” into the tire during rotation or appear from there.

Also, in case of excessive wear of the spacers, the depth of the groove of the tire and the chain shanks can cling to the bottom of the groove during movement, could decrease below an acceptable level.

In this case, too, there will be excessive heating of the circuit and bus. After all, apparently this chain is not the first for the tire.

In addition, the fact that the saw stalls when the chain is jammed indicates a malfunctioning clutch. There is either dirt between the clutch cams and its cup, or the cup itself is deformed. Clutch springs may be stretched.

Not oil arrives on the chainsaw chain: premises and solutions

When moving saw chain chainsaws in the tire groove due to friction, a lot of heat is released. If no oil comes in chainsaw chain, we need to suspend work and take what remains to be done to our client of measures to eliminate the malfunction of a complex of accounting lubrication programs. The combination of huge loads and overheating of the headset is accompanied by its accelerated wear and premature failure.

All chainsaws and their electronic counterparts are equipped with the same type observing the principle of action systems, by means of which the lubrication of the tire, the saw chain and its drive parts is realized.
The standard composition of this device includes a tank from which the chain butter It is supplied to the pump inlet with a fixed or adjustable capacity.
Next, the working fluid in a metered amount enters the groove of the tire when the shanks saw chain moderately distributed over the entire headset and the working surface of the crown of the drive sprocket.

Tires for product sets over 400 mm are equipped with a driven sprocket. Repeated bearing lubrication is done personally, after 6-8 hours of production.

Symptoms of a malfunctioning accounting software package

The right choice of consumable lubricant and the perfect work of a set of accounting programs contribute to true lubrication, efficient cooling of the saw equipment and a workable version of the development of its resource.

There are several external signs that the chain on the chainsaw is not lubricated. First up is:

constant oil level in the tank;
increased load on the engine;
accelerated wear of the cutting edges of the saw links;
the corresponding smell of overheated wood.

In the most ordinary variant, a prerequisite for oil starvation, you will more like clogging the oil channels with sawdust. This flaw is typical for economical headsets that do not have comfortable access to problem areas.
