Not oil enters on chain chainsaws: background and solutions
When moving saw chain chainsaws in the groove of the tire due to friction, a huge amount of heat is released. If not oil enters on chain chainsaws, you need to stop 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, chainsaws and their electronic counterparts are equipped with systems of the same type according to the principle of operation, which lubricate the tire, saw chain and its drive parts.
- The standard composition of this device includes a tank from which chain oil is supplied to the pump inlet with a fixed or adjustable capacity.
- Further, the working fluid in a metered amount enters the groove of the tire, in which the saw chain shanks are moderately distributed throughout the headset and working surface crown of the leading sprocket.
Tires of productive headsets with a length of 400 mm or more are equipped with a driven sprocket. Repetitive bearing lubrication is done personally, after 6-8 hours of production.
Signs of a malfunctioning lubrication system
The correct choice of consumable lubricant and the ideal operation of the system contribute to true lubrication, effective 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 reservoir;
- 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 version, a prerequisite for oil starvation may be clogging of oil channels with sawdust. This flaw is typical for economical headsets that do not have comfortable access to problem areas.

Gears for driving pumps of budget chainsaws are mostly polymer. Advanced in terms of technical equipment branded models with adjustable output are equipped with drive mechanisms made of non-ferrous metals. The cost of such systems is offset by economical, up to 50% consumption of the working fluid.
Self troubleshooting feature
Complete self repair chainsaw chain lubrication, under all equal conditions, requires knowledge of the interaction of all elements of the system, the availability of tools and locksmith skills.
Restoring the operating parameters of many chainsaws involves partial or complete dismantling accessory equipment. To perform complex repair work it is better to use the possibilities and technical potential of service workshops.
Parts with stripped threads and damaged splines, as well as non-separable structures that are equipped with the lubrication system of popular chainsaws Calm 180 and other models of the same type are subject to replacement.

If, when the tank is filled, oil does not enter the headset design, the cause should be sought in the pump itself. Dismantling and disassembling the mechanism will help identify faulty parts and eliminate the malfunction by replacing them.
Checking the system for oil output and performance
Oil filter contamination is manifested by a significant decrease in pump performance. It is easy to check this parameter. To do this, you need to hold the headset of the saw operating at working speeds over clean slate paper.
By the density and size of the oil strip, one can confidently judge the state of the system and the complexity of the upcoming repair.
When asked why the repaired lubrication system works, but oil does not go to chain in the right amount - there is no clear answer. The reason for the failure may be errors made during assembly, failure of regular adjustments, discrepancy between the density and viscosity of the selected composition and the declared characteristics.
Oil starvation of the headset is possible when a longer productive tire is installed on a household saw with an unregulated pump, which is equipped with professional-grade chainsaw equipment.
The specifics of the repair of Chinese chainsaws
A significant share of the imported chainsaw assortment is made up of Chinese-made chainsaw equipment. Many models have been copied with more or less success from the best European developments.
One of important systems chainsaws, without which work is impossible, is the system of forced lubrication of the chainsaw chain. It's no secret that at the time of saw operation, the chain rubs against 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 chain, 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 increased adhesive properties, this is necessary to evenly distribute the oil around the entire perimeter of the tire and keep it on it even at high chain speeds. Let us consider in more detail the oil supply system implemented in modern chainsaws.
Lubrication system device
Depending on the chainsaw brand, the details of the lubrication system may differ slightly in design, but their total number and connection diagram remain unchanged.
The main components of the lubrication system are:
Principle of operation
The main node of the system is the pump. The principle of its work is the following. 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 forces the oil to move along it towards the tire.
The end of the oil channel is located at the point of contact of the tire with the crankcase of the tool, where there is a longitudinal groove, on which, when the tire is installed, its oil channel falls.
The groove is necessary to ensure the supply of oil to the tire, regardless of the degree of tension of the chainsaw chain. Simply put, no matter what position the tire is in at the time of operation, oil will fall on it through the groove.
Further, a chain is included in the lubrication process, on the links of which, depending on the chain model, there is either a groove or a hole through which the oil is accelerated throughout the entire tire. With an increase in engine speed, the oil flow rate also increases.
Some models of chainsaws are equipped with pumps that additionally have capacity adjustment, and if necessary, the amount of oil supplied by the lubrication system can be increased or decreased.
This feature is quite convenient, because it allows you to save and not waste excess oil.
Malfunctions of the lubrication system 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 common malfunctions inherent in all chainsaws and individual ones, which may vary depending on the type of pump and worm gear installed on specific model. Let's start to understand the malfunctions in order.
Working with a chainsaw if the chainsaw chain is not lubricated is prohibited. This adversely affects the bar, sprocket and chain, and can also result in serious repair costs.
Signs of a malfunction in the lubrication system, checking its performance
- The chainsaw chain is dry and has a pale tint 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.
- Decreased cutting efficiency on a sharp chain
All these signs indicate that the lubrication process is proceeding with violations. 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 place where the oil line ends. If oil is coming in, most likely it is not enough for normal lubrication and the filter needs to be cleaned or replaced and, if possible, adjusted supply. In the case when it does not, the problem is more serious and requires further diagnosis.
There is a way to check the oil supply without removing the tires. To do this, it is necessary to direct the end of the tire towards, for example, a freshly sawn chock from the side of the cut and increase the speed as much as possible, while trying to keep the end of the tire at a distance of no more than 10 cm from the chock. If oil spots begin to appear on its surface, then oil is supplied.
Troubleshooting
Once it has been determined that no oil is supplied, further diagnosis is possible only if the oil system. Of course, changing the filter 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, therefore, without skills in repairing gas tools, it is better to entrust repairs to professionals.
The most frequent malfunctions
Individual failure of the Stihl MS 180 lubrication system
Due to the fact that the Stihl MS 180 is one of the most common models of chainsaws, I would like to dwell in more detail on one malfunction inherent only to it and describe how to eliminate it without replacing parts.
Quite often, on the Stihl MS 180 chainsaw, there is a depressurization of the oil line in the place where the oil line coming from the tank is installed in the saw body. You can determine the malfunction by characteristic grease smudges on the bottom of the tool.
To eliminate the malfunction, it is necessary to remove the chainsaw handle, remove the hose from the mounting hole, clean and degrease. After all these manipulations, apply on seat sealant hose and install in the chainsaw body.
You can learn more about troubleshooting and a complete diagnosis of the Stihl chainsaw lubrication system by watching a video that shows step by step the process of disassembling and repairing the lubrication system.
Conclusion
In modern chainsaws, a reliable supply of lubrication for the chain is organized, in case of violations in the operation 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 experience in repair, this guarantees the quality of the final result.
Why not oil enters on a chainsaw chain?
If during the work oil enters on the chainsaw chain, you need to find the cause of the problem. As a matter of fact the reasons influencing the myth process, you will like a lot. You should disassemble the chainsaw and identify the main problem. Possible prerequisites for this process will be described below.
The reason for the lack of oil supply to the chain during the operation of the chainsaw, you will like several reasons for their identification, you need to disassemble the chainsaw.
Probable causes of non-receipt of fuel
Oil may not flow to the chain only if there are 2 breakdowns. These include:
- tasks with air suction;
- drive failure oil pump.
The main characteristics of the chainsaw chain.
The main cause of failure is air leakage. This can happen due to depressurization of the oil hose during the operation of the chainsaw. Under 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, most likely, elasticity was lost. For the upcoming operation of the chainsaw, it is purposeful to change the hose.
2nd reason - drive failure oil pump. In the common people, this part is called a worm. When the drive fails, the oil will stop being supplied to the chain. The oil pump drive is a round plastic ring with grooves inside. The constant introduction of the chainsaw leads to wear of the internal parts, and as a result, the iron hook located inside the drive is punctured. After this breakdown, the oil stops flowing to the chain.

It is better to create a cut with a significant amount of lubricant. If you have to work with soft tree species, 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 oil leaks or does not flow at all, you need to identify the cause of the breakdown. It is not recommended to operate the tool before repair.
Choosing fuel, you need to do it right. The desire to save leads to the fact that the chain quickly burns out. To avoid unpleasant consequences, you do not need to choose oil produced in China. Preference should be given to unusual firms. In their own price category, they are significantly higher, but their quality is better.
Troubleshooting Circuit Service Issues
During the operation of the chainsaw, you need to constantly look after the chain lubrication. Because this part works in the most languid terms. The chain is exposed to constant overheating, dust and abrasive particles are clogged there. This negatively affects its service life. To correct the situation will allow a special lubricant. It is fed to the chain from the tank, thereby ensuring unhindered operation.
If in your operating time there is no lubrication, the highest possibility of overheating remains. When oil is not supplied, the chain begins to stretch. With all this, the possibility of its jamming or spontaneous jumping off remains, and as a result, a person can be seriously injured.
The channels through which fuel is supplied can be clogged with small particles, therefore it is purposeful to clean them from time to time. It is also important to keep an eye on the oil level in the reservoir. Debris in the channel becomes a common cause of failure of the chain brake. This can be bad for your work.
Permanent cleaning of channels and general care behind a chainsaw will allow the tool to work for a long time.
Every year, technology becomes more advanced, which greatly facilitates the work of modern workers. New improved models are constantly appearing on the market. But any tool requires proper care. The Stihl 180 chainsaw is no exception. In this article we will talk about how to properly repair this tool.

In order to properly carry out repairs, you should deal with the internal mechanism. This rule applies to any instrument. Let's look at the most common problems that can arise when working with a chainsaw.
1.Owners often encounter oil leakage, which is usually used to lubricate the chain. This may be due to poor tightness at the connection points of the hose from the oil tank and pump.
To fix this problem, the instrument must be completely disassembled. After that, it is necessary to check the connections and, if necessary, replace the hose with a high-quality analogue. 
If you cannot buy a new hose, you should remove the old one and degrease the seat and the hose itself. After that, it is necessary to install self-tightening clamps that reliably ensure the tightness of the connections. This approach will solve this problem.

2. If the saw does not start, you should carry out a thorough diagnosis of the tool. First you need to check air filter and performance of the candle. To do this, it should be unscrewed and dried.
If the candle is found fuel mixture- means there is an excess of fuel. The cause may be a poorly adjusted carburetor or a violation of the rules for starting. See if the access that supplies gasoline is open.
To do this, open and close the gas tank cap. You also need to check the combustion chamber. After the work done, check the serviceability of the candle and change it if necessary. 
3. The cause of the breakdown may be a clogged breather. Thus, during operation, a vacuum is formed in the fuel tank, which affects the fuel supply. This may be due to an unadjusted carburetor, clogged channels or an air filter.
To fix the problem, you should repair the valve, due to which the pressure equalizes when the fuel is supplied. To do this, the breather should be carefully cleaned with a needle.
To adjust the carburetor, you need to use three screws - the largest and smallest turns. Adjustment should be carried out strictly according to the instructions for repairing a chainsaw.
