Oil does not flow on the STIHL 180 chain

Lubrication system device

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

The main components of the lubrication system are:

  • oil tank located, as a rule, in the engine crankcase.
    does, stihl, chain
  • 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 engine to the pump.
  • A chainsaw tire, it can also be considered an element of the lubrication system, since it has special holes for supplying oil, by the way, the chain itself is involved in the transportation of oil and, accordingly, also has some elements designed specifically to provide lubrication.


Diagnostics should begin with an inspection and check of the oil receiver (filter) of the STIHL 180 saw. As a rule, if the filter is heavily soiled, the oil supply may stop.

In order to save money, you can try to clean a clogged filter by rinsing it thoroughly in gasoline.

The STIHL MS 180 chainsaw is the ultimate tool for logging and other woodworking operations. It is one of the most widely recognized gardening devices and is armed with functional abilities.

The tool weighs about 4 kg. The power achieves 1.5 kW, and the bus length is 35 cm.

Note that from a semi-professional device for this model of the saw got electric ignition and a rather quick tension of the chain. In addition, the STIHL MS 180 saw has 2 tanks designed for gasoline and oil consistency.

Reduced vibration is one of the main features.

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

It must be emphasized that it is no better to disassemble this saw without the help of others without special instruction, in this case it is better to entrust the device to the masters.

In the operation of the system, it perceives a specific role and the oil line of the chainsaw, at the end of which there is an oil receiver. The oil receiver is additionally a filter. On the 2nd side of the oil hose, a rubber expansion is made, with the help of which the hose is installed in the body of the STIHL 180 chainsaw immediately behind the oil pump.

Adjusting the Oil Supply to the Chain of the STIHL Chainsaw

Certainly, whoever owns chainsaws knows how important is not a bad and high-quality oil. And, everyone dreams, there is no need to say what is really, that this is a typical “life force” of this device for the production of real and effective work. Today there is an unlimited number of oils and, as the proverb says, the choice is very large.

But, often, not every owner of electrical engineering of this kind knows what kind of oil you need to take for your own steel friend, so that the work of the chainsaw is not only easy, but also productive. Therefore, below will be considered the issue of the correct choice of the STIHL manufacturer. Also, what it is, to assist the chainsaw in its time in its specific activities, and not harm it. What is needed, let’s get started.

Choosing the right oil

After you purchased the device, the question immediately arose: what kind of oil should you put in your STIHL chainsaw? If you properly take care of the equipment intended for work in the construction and gardening sector, then you can significantly increase the level of activity of the direct operation of the device itself not to encounter breakdowns of a various nature.

It is worth noting that the most important factors in the immediate operability of the device is the use of the correct lubricant and fuel. Although the main problems for the owners of this technique are precisely with the choice of oil for their “favorites”. At this point you can find out how to select a lubricant specifically for STIHL chainsaws.

Chainsaw STIHL 180 stalls when you press the gas. how to solve the problem?

If the model stalls when the engine rises, then this indicates a clogged fuel filter. Because of this, the element is not able to pass fuel, which is necessary to increase the speed of the STIHL MS 180 internal combustion engine.

In this case, remove the fuel filter and rinse it with clean gasoline. If this does not help, then you need to carefully check the factory air filter. If a large amount of debris has accumulated in it, then it will need to be replaced with a new element.

Why is pouring a candle on a STIHL 180 chainsaw?

The essence of this breakdown lies in problems with the carburetor. For repair, you will need to remove this element, and also check its membrane. In working order, the part must be not only intact, but also elastic. If the membrane is hardened, then it will need to be replaced.

Before reassembling the STIHL MS 180 carburetor, it must be cleaned of dust and carbon deposits. To do this, use compressed air in a cylinder. After the assembly is completely dry, it can be assembled and installed back on the chainsaw.

The proportion of oil and gasoline for the STIHL 180 chainsaw

Before you start working with the German STIHL MS 180 model, you will need to refuel it. Compliance with the amount of gasoline and engine oil used is important. As indicated in the factory operating instructions, for mixing fuel, you should adhere to a ratio of 1:50, that is, in 50 parts of gasoline, you will need to stir 1 part of oil. Thus, in 1 liter of fuel used, you need to dilute no more than 20 ml of oil.

The quality of fuel and oil is also important. To refuel the STIHL MS 180 chainsaw, the manufacturer recommends using gasoline with an octane rating of at least 90. Engine oil for 2-stroke engines manufactured by STIHL is suitable as a lubricant.

What to do if the saw stalls at idle speed?

If the STIHL MS 180 chainsaw stalls some time after starting in idle mode, then this indicates a breakdown of the fuel pump. To verify this, you need to use a vacuum gauge. If the device showed a pump malfunction, then the mechanism will need to be replaced.

Running in a STIHL MC 180 chainsaw. tips for beginners

The purchased STIHL chainsaw in the MS 180 configuration must be rolled up. This will make it possible for the parts of the tool to rub in for the further coordinated work of the main mechanisms of the saw.

Before running in your STIHL 180 chainsaw, fill it with new fuel mixture. You will also need to fill in fresh oil to lubricate the chain of the STIHL 180 chainsaw. The further procedure is as follows:

  • First you need to release the chain brake to eliminate the risk of body melting in the place where the clutch is installed. The brake will also protect the operator from possible damage;
  • Next, start the saw and let it idle for 15 minutes. In this case, every 30 seconds you need to press the gas lever;
  • After that, you need to transfer the saw to work as usual. At this time, you should start sawing thin branches, gradually moving on to work with larger branches.

”Typically, it takes no more than 30–35 minutes to prepare an instrument. During the running-in and further use of the STIHL MS 180 saw, always make sure that no nails or other hard objects fall under the chain.

DIY STIHL 180 chainsaw carburetor adjustment

The carburetor setting of the STIHL MS 180 is essential to ensure efficient saw operation when used at full speed and to save fuel. To complete this procedure, you will need to clean the air and regular fuel filter.

You can adjust the carburetor of the model using three standard screws. Screws L and H are needed to preset the ratio of the mixture of air and fuel, which is regulated by different positions of the throttle valve. The S screw is responsible for fine tuning the idling of the chainsaw. The procedure for setting up the carburetor is as follows:

  • First you need to start the tool and start turning the screws H and L alternately clockwise until it stops. Then both screws will need to be slowly turned 2 full turns in the opposite direction;
  • After that, you need to find the maximum engine speed when the saw is idling. To do this, screw L should be turned alternately in different directions. In this case, the screws should not emit creaking sounds. As soon as the basic maximum revolutions are found, it will be necessary to slowly turn the screw L a quarter of a turn against the direction of the clock hand;

After that, you need to check the operation of the engine one by one at minimum idle, and then at maximum speed.

The gears of the pump drive of budget chainsaws are mostly polymer. Proprietary variable capacity models, advanced in terms of technical equipment, are equipped with drive mechanisms made of non-ferrous metals. The cost of such systems is compensated by an economical, up to 50% consumption of working fluid.

The specifics of the repair of Chinese chainsaws

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

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

Self-help troubleshooting feature

A full-fledged independent repair of 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 the partial or complete dismantling of the accessory equipment. To carry out complex repairs, it is better to use the capabilities and technical potential of service workshops.

Parts with stripped threads and damaged spline joints, as well as non-separable structures that complete the lubrication system of popular STIHL 180 chainsaws and other models of the same type must be replaced.

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

The main reasons why STIHL 180 oil is not supplied

the main reasons why STIHL 180 oil is not supplied.

Reasons for Decreased System Performance and Efficiency

In the required amount, oil is not supplied to the chainsaw chain for several reasons. The most common failures include:

  • clogging of the filter located in the oil tank;
  • mechanical failure of one of the elements of the pump worm drive;
  • in winter, the performance of the pumping device decreases due to filling the system with too thick oil.

In the latter case, the drive and all pump parts operate under increased loads, initiating serious mechanical damage.

Checking the system for oil output and performance

Contamination of the oil filter manifests itself as a significant decrease in pump performance. It is not difficult to check this parameter. To do this, hold the headset of the saw operating at working speed over a clean sheet of 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.

There is no definite answer to the question why the repaired lubrication system works, but oil does not go to the chain in the right amount. The reason for the failure may be mistakes made during assembly, failure of standard adjustments, discrepancy between the density and viscosity of the selected composition to the declared characteristics.
