Chainsaw Oil Flows

STIHL MS 180 oil supply repair

The owners of this model of the tool should be prepared for the fact that they may face such an unpleasant moment as a leak of oil for lubricating the chain. Oil can leak out while working with the tool and even when just lying down without action.

What is the reason for this phenomenon? The fact is that oil leaks due to leakage in the area where the hose from the oil tank and pump is connected.

In order to solve the STIHL MS 180 oil supply problem, it is advisable to disassemble the device.

Solution to the problem:

• Check the hose, if it is damaged, then replace it with another one. Or try to degrease the hose and rinse, and put on a sealant, everything should work.
• Check the filter oil for breakage, clean it (if you filled in the waste)
• There may also be a clogged zapune, this creates a vacuum in the fuel tank and affects the fuel supply. The problem may be in the adjustment of the carburetor and the channels, or the air filter, may be clogged, you need to thoroughly clean the filter and carburetor channels.

In general, the main problem is due to poor oil.

It is not recommended to pour oil into a chainsaw that is not intended!

Chainsaw chain lubrication system

To supply oil for lubricating 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 overestimated adhesion characteristics, 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. Oil flows, the chainsaw outlet is in the place where the chain tension bolt goes from here. Let’s take a closer look at the oil supply system implemented in modern chainsaws.

The STIHL MS 180 chainsaw is an indispensable tool for logging and other wood construction work. It is one of the most acclaimed gardening devices that comes with multifunctional features.

The tool weighs about 4 kg. The power reaches 1.5 kW and the busbar length is 35 cm.

Note that from a semi-professional device for this model of the saw got electronic ignition and a fairly fast chain tension. In addition, the STIHL MS 180 saw has 2 tanks for gasoline and an oil mixture.

Reduced vibration is one of the main features.

This result is achieved thanks to 4 shock absorbers. It’s no secret that high depreciation has a detrimental effect on human health and in Europe they have been struggling with it for a long time.

It should be noted that it is not advisable to disassemble this saw on your own without special instructions, in this case it is better to entrust the device to the masters.

Carburetor STIHL MS-180

The STIHL MS-180 carburetor is equipped with one idle adjustment screw. Full load jet is not adjustable, i.E. It cannot be changed.

You need to know the basic rules for adjusting the idle speed:

1) check the air filter, if necessary, change it;

2) check the spark arresting grille, if necessary, change or clean it. Then you can turn on the engine and then warm it up.

Lubrication system device

Depending on the brand of the chainsaw, the details of the lubrication system may differ slightly structurally, but their total number and connection diagram remains constant.

The main components of the lubrication system are:

• The oil tank is usually located in the engine crankcase.
• Filter element, installed in the tank.
• The oil line is a small diameter oil-resistant rubber hose.
• The heart of the system is the oil pump.
• Worm gear gear transmission force from the motor to the pump.
• A chainsaw tire, it can also be considered an element of the lubrication system, because it has special holes for supplying oil, by the way, the chain itself participates in the transportation of oil and, accordingly, also has some elements designed specifically to provide lubrication.

How to fix oil leaks on a chainsaw.

One of the cases of eliminating spontaneous leakage of saw chain lubricating oil from a chainsaw. Repairs

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

Fuel tanks are selected exactly according to the volume. At maximum output, it is allowed to choose components with a small amount of oil.

Chainsaw fuel system: 1. fuel filter, 2. carburetor, 3. manual pre-priming pump.

If the carburetor is adjusted correctly, the fuel will be consumed in the allowable volume. Otherwise, it will end too quickly.

It is normal to deplete fuel slowly during saw operation. If it is absent, the chain is not lubricated correctly, so work with the chainsaw must be harmonious. It is necessary not only to be able to eliminate breakdowns, but also to identify them yourself.

Cutting is desirable with a significant amount of lubricant. When working with soft wood, a small amount of fuel is supplied.

The chain must always be well lubricated. This will avoid smoke and further failure of the entire chainsaw. If oil leaks or does not flow at all, it is necessary to identify the cause of the breakdown. It is not recommended to operate the tool before repair.

When choosing a fuel, you must do it correctly. The desire to save money leads to the fact that the chain quickly breaks down. In order to avoid unpleasant consequences, it is undesirable to choose oil, the manufacturer of which is China. Preference should be given to original firms. In terms of their price category, they are much higher, but their quality is also better.

Fuel tanks are matched exactly to the volume. With the highest output, it is allowed to choose components with a small amount of oil.

Prerequisites for stopping the oil supply in the chainsaw

A concise overview of why the oil in the chainsaw has stopped being supplied to the tire from the tank Support our channel with whatever you can, this is you.

Chainsaw fuel system: 1. fuel filter, 2.7. carburetor, 3. manual pump for preparatory pumping.

Slow reduction of fuel during the lifetime of the saw is a common process. If it is absent, the chain is lubricated incorrectly, 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.

You can manually change the fuel flow. The correctness of the operation of the lubrication complex of accounting programs is determined by the method of bringing the tire. If oil splashes appear, it means that our client remains adjusted correctly.

Troubleshooting Circuit Problems

The main unit of the system is the pump. The principle of its operation 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.

CHAINSAW DOESN’T GO OIL ON THE CHAIN.

To supply oil for lubricating 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 overestimated adhesion characteristics, 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. Oil flows, the chainsaw outlet is in the place where the chain tension bolt goes from here. Let’s take a closer look at the oil supply system implemented in modern chainsaws.

A very frequent breakdown in a chainsaw is a chainsaw that stops supplying oil to the chain. Some people wonder what it is.

During the operation of the chainsaw, you need to constantly look after the chain lubrication. Because this part works in the most languid criteria. The chain is exposed to constant overheating, dust and abrasive particles are clogged there. The entire range has a negative impact on its service life. A special lubrication will allow you to correct the situation. It is fed to the chain from the tank, thus ensuring smooth operation.

The channels through which the fuel is supplied are, of course, clogged with small particles, therefore it is purposeful to clean them from time to time. It is essential to look at the oil level in the reservoir. Debris in the duct is a common prerequisite for chain brake failure. It can be bad for your job.

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

However, what to do, provided that our client is adhered to, and the oil flows anyway. You need to make sure that the chainsaw is working correctly. It is entirely possible that it was assembled incorrectly. If no damage has been identified, it is recommended to take it to a workshop. Sometimes it is necessary to change the pump, but this must be done provided that the saw is new. Old tools are leaking due to worn-out tank.

The current state of the chainsaw can only be assessed by specials. In the absence of knowledge or lack of confidence in one’s own abilities, it is better to entrust the repair of the tool to a specialist.

During the operation of the chainsaw, it is necessary to constantly monitor the lubrication of the chain. After all, it is this part that works in the most difficult conditions. The chain is subject to constant overheating, dust and abrasive particles are clogged into it. All this negatively affects its service life. A special lubricant will correct the situation. It is fed to the chain from the tank, thereby ensuring smooth operation.

The channels through which the fuel is supplied can be clogged with small particles, so it is advisable to periodically clean them. It is also important to monitor the oil level in the reservoir. Debris in the duct is a common cause of chain brake failure. It can negatively affect work.

Continuous cleaning of the channels and general maintenance of the chainsaw will allow the tool to function for a long time.

But what to do if all recommendations are followed, but the oil still flows. Make sure your chainsaw is working properly. It is likely that it was not collected correctly. If no damage has been identified, it is recommended to take it to a workshop. In some cases, it is necessary to replace the pump, but this must be done if the saw is new. Old tools are leaking due to worn out reservoir.

The current condition of the chainsaw can only be assessed by a specialist. In the absence of knowledge or self-doubt, it is advisable to entrust the repair of the tool to a professional.

Benefits of branded oils

Many domestic and foreign manufacturers specialize in the production of special motor oils, but the highest rating indicators are for branded products Stihl, Husqvarna and Makita.

Only in certain parameters are the domestic motor oils of the Lukoil trademark inferior to the branded assortment.

The list of advantages of branded motor oils:

• Economical consumption;
• Stability of performance under difficult operating conditions and during long-term storage;
• The minimum amount of toxic compounds in exhaust gases;
• Almost complete absence of carbon deposits.

According to the American classification, API-TB oils can be used for work in household and professional models. The Japanese counterpart is JASO-FB and JASO FD. Preparation of a combustible mixture using oil for 4-stroke engines is strictly excluded.

Red, green or any other color of oil determines the product’s belonging to the assortment of a certain manufacturer, therefore, when determining the characteristics of the material, it is not taken into account. You should be extremely careful when choosing engine oil of unknown composition and origin.

Until you receive additional information about the quality and operational parameters, it is better to temporarily refuse to use such material.

It is allowed to mix engine oils of the same type in composition and purpose, produced by brands known for the quality of their assortment. Under no circumstances is it allowed to mix mineral and synthetic oils.

Self-selection criteria

A large assortment allows you to choose oil that fully corresponds to the class and characteristics of the chainsaw, the conditions of its subsequent operation.

• For budget models, you can use oils of the Standard category, for professional chainsaws, consumable lubricants of the Super and Ultra categories are recommended.
• To prepare a full-fledged fuel mixture for a chainsaw, it is advisable to use branded oils or their branded counterparts recommended by the operating instructions. In particular, Stihl and Husqvarna engine oils of the same composition and application are completely interchangeable.

Experts recommend that owners of chainsaws exclude from the scope of attention motor oils intended for two-stroke engines of mopeds, boat motors and other mechanized household appliances.

The power units of this equipment operate in more comfortable conditions, which makes the requirements for their operational characteristics less stringent.

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, having water and mechanical impurities in their volume are not suitable for fuel preparation.

• The opinions of experts on the use of different brands of gasoline are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 with European standards is recognized.
• On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. It is possible to use this fuel for the preparation of fuel for a chainsaw only if you are fully confident in its quality.
• The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the performance properties of motor gasoline with a lower octane index.

Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.

Oil dosage in Chinese version

Many Chinese-assembled chainsaws are simplified copies of popular European-developed models. The lack of special materials and proprietary technologies contributes to the preservation of the outdated proportion of gasoline and oil in a ratio of 25: 1.

The doubled consumption of engine oil is compensated by its lower cost. According to the developers, original components are introduced into the composition of Chinese oils, which help to increase the wear resistance of power units and the real extension of their assigned resource.

According to the conclusion of independent experts, the quality of the best brands of Chinese motor lubricants corresponds to those of European manufacturers in the middle price range. This is the level of branded motor oils of the Standard group and partially. Super.

Measuring containers

To maintain the correct proportion of gasoline and oil, the calculation table printed on the saw body can be used. Branded containers of leading manufacturers of engine oils are equipped with built-in measuring devices that ensure accurate dosage of oil for different volumes of fuel mixture.

Volumetric utensils are included in the factory set of many models of budget chainsaws. In some cases, a 20 cm3 medical syringe will help to dilute gasoline with oil in a given proportion.

Lubricants

Stricter selection criteria for the oil component. In the best variant, it is a mineral or semi-synthetic engine oil recommended by the manufacturer, intended for operation in high-speed, air-cooled two-stroke internal combustion engines.

The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic counterparts are distinguished by improved performance and compliance with environmental standards.

Synthetics:

• Retain working properties in a wide range of operating temperatures;
• Does not form carbon deposits;
• Contains detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.
