Chainsaw Stihl MS 180 - features of operation and maintenance

Shtil chainsaws are quite small in size. They have a high level of cutting ability and are more powerful. These advantages attract buyers to the models of this company.

The chain lubrication system of the Stihl saw consists of the following components:

• Guide bar.
• Saw chain.
• Oil pump.

The oil supply through the pump has a special adjustment. An important fact is that the chain is lubricated during the entire operation of the saw, so the oil product must flow continuously onto its surface.

During operation of the tool, lubricant comes out of the bar groove and is immediately absorbed by sawdust, so the chain is automatically lubricated. There are models that have a dosage of material that is supplied to the chain. Low price models are equipped only with a hand pump. It works due to the action of the drive on the handle.

How much gasoline does a chainsaw consume?

The fuel tanks of most gasoline saws have a volume of 0.3 to 1.0 liters. How often you need to pour the fuel mixture into the chainsaw depends on the chosen brand, engine power and intensity of work. In logging and wood construction, professional chainsaws are used, characterized by high power and a long period of continuous operation. For housekeeping in a village house, in a country house, or for the occasional production of wood products, less productive, but lightweight and convenient household models are used. For a professional tool with a power of 5-6 kW, fuel consumption when sawing logs can reach 3.0 l/hour. For less powerful models with a 1.5-2.0 kW engine, it fluctuates at 0.6-0.8 l/hour.

Lubricant selection criteria

After purchasing the device, the question may arise about choosing oil to fill the Stihl chainsaw. After all, proper care of equipment increases its performance and saves you from all kinds of breakdowns. The performance of the saw directly depends on the use of good fuel and lubricant.

Stihl chainsaws have a carburetor two-stroke engine and 2 tanks (gasoline and oil). To choose the right oil for a Stihl saw, you need to know its criteria:

1. It is necessary to determine the manufacturer , because in domestic models they use simple oils (for motorcycles) in a ratio of 1 to 25, and foreign ones use branded lubricant products in a ratio of 1 to 40 (proportions of oil to gasoline). In fact, the owners themselves determine which one to use. You should be prepared that improper use will result in a decrease in power and productivity. Most people use motor oil; if not, then transmission oil. Experts advise using the latter for this manufacturer.
2. You need to know the color. For chainsaws with a two-stroke engine, red, green, and blue colors are suitable.
3. Compound.

Requirements for the fuel used

The main fuel component of a carburetor engine is unleaded gasoline. You should not experiment with the question of what kind of gasoline to pour into a chainsaw. Its brand must meet the requirements set out in the instrument’s passport and instructions for its use. Violation of this rule may result in:

• to a sharp decrease in saw power and uneven operation when using gasoline with a lower octane number;
• to overheating of engine elements when the recommended octane number exceeds the nominal value.

It is strictly prohibited to dilute gasoline for a chainsaw with questionable mixtures, so you should use the services of the nearest gas station. We must remember that in addition to the octane number, automobile fuel has many other indicators that change depending on the season.

Do not store a large stock for a long time. In winter conditions, the engine may not start on gasoline purchased in the summer.

List of oils by price/quality ratio

How to dilute gasoline for a Stihl 180 chainsaw

The Stihl MS 180 chain saw is used for collecting firewood in private homes and on small farms, for landscaping the garden, for clearing bushes, for cleaning the area and performing various tasks of varying complexity, including chopping and sawing wood. This is truly a multifunctional device. In addition, various attachments can be used for repair and construction work.

Device Features

The Shtil 180 chainsaw is simple, and the developers have made great efforts to ensure that the household appliance has all the advantages of a professional model and is accessible to beginners. Design features allow users to use devices with different levels of learning:

• The carburetor chain of the Shtil 180 chainsaw allows you to independently adjust the unit using a specially designed screw.
• The design allows the use of tires of different sizes. The standard tire supplied by the manufacturer for the Calm 180 chainsaw is fourteen inches; if necessary, you can adjust the model to sixteen inches. This feature can significantly improve productivity.
• A two-stroke single-cylinder engine runs on a mixture consisting of only two components. Gasoline and oils, which must be handled with the utmost responsibility, since quality and service life directly depend on this.
• To start the engine, you need to tighten the starter wire.

Self-selection criteria

A large assortment allows you to choose an oil that fully corresponds to the class and characteristics of the chainsaw, and 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 complete fuel mixture for a chainsaw, it is advisable to use branded oils or their branded analogues recommended in the operating instructions. In particular, Shtil and Husqvarna motor oils of the same type in composition and application are completely interchangeable.

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

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

Oil dosage in Chinese version

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

The doubling of engine oil consumption is compensated by its lower cost. According to the developers, original components are introduced into Chinese oils that help increase the wear resistance of power units and actually extend their designated service life.

According to independent experts, the best brands of Chinese motor lubricants correspond in quality to analogues from European manufacturers in the mid-price range. This is the level of branded motor oils of the Standard group and partially Super.

Why do you need to dilute the lubricant?

At the very beginning, it is necessary to understand the reason for the dilution of fuel. The mixture used for a chainsaw is diluted primarily to extend the service life of its owner. The instructions for it strictly prohibit operation without diluting gasoline.

The basis of the chainsaw motor is a piston internal combustion engine. It consists only of a cylinder, so it does not have additional systems for lubricating parts. The mixture enters it, settles, lubricates the piston rings and walls. In tools such as chainsaws , oil and gasoline act as a unique lubricating fluid. The mixture extends the service life of all parts.

Mixing technology

In addition, it contains additives that are beneficial for engine performance. It has antioxidant, preservative and other properties, which are also useful for the engine and its parts.

Why you need to adhere to the appropriate proportions when mixing

Having decided on the need to mix gasoline with oil in a chainsaw, you will need to find out why you need to adhere to the appropriate proportions when mixing the fuel mixture into a chainsaw.

• If you fill in gasoline with a low oil composition, this will contribute to the development of all of the above consequences - engine overheating, scuffing of the CPG and jamming of the internal combustion engine. Only in this case the internal combustion engine will work a little longer than on pure gasoline.
• If you fill the tank with fuel with a high oil content, then this is also dangerous, because in this case, in addition to strong smoke, carbon deposits will be observed on the cylinder walls, muffler and other parts. There will be a decrease in power and a decrease in the productivity of the unit. In this case, the engine will run longer, and if deposits occur, they can be removed.

To eliminate negative consequences, and at the same time increase the service life of the tool, it is recommended to understand how much oil should be added to gasoline for a chainsaw in order to achieve ideal engine operation.

Instructions for making a fuel mixture

Let's find out in more detail how gasoline is diluted with oil. Some tool owners do this - pour clean gasoline into the tank and add the required amount of oil. After this, close the lid and stir. This method of diluting gasoline with oil is incorrect. Instructions for preparing a gasoline-oil mixture are as follows:

1. You need to take a plastic bottle of equal volume - 1 or 2 liters. You can use a 1.5 liter, but this can cause confusion when adding oil.
2. Fill the container halfway with gasoline.
3. Add lubricant. It is recommended to dose the oil using a syringe. It is advisable to use a 5 cc syringe, which will allow you to measure exactly 25 ml of oil.

4. After adding the lubricant to the container, shake thoroughly.
5. Add gasoline until the container is full and mix thoroughly again.

6. The result is a ready-made gasoline-oil mixture for a chainsaw, which should be used within 1-2 weeks.

Many people do not pay enough attention to storing the prepared mixture, and therefore can immediately prepare 5 liters and use it throughout the year. However, this approach is extremely incorrect, since the shelf life of the finished mixture is 15 days. If you are sure that gasoline does not contain alcohol, then you can store the finished mixture longer - up to 3 months. After this, the mixture loses its properties, having a negative effect on the internal combustion engine.

Interesting to know! Make it a rule not to prepare chainsaw fuel in large quantities. It is better to prepare 2 times one liter, than to immediately mix 2 liters, which will remain and will be stored indefinitely.

After combining gasoline with oil, all that remains is to refuel the tool and start using it. When refueling a chainsaw, there are some important points that should be taken into account. We'll look into them.

Chainsaw oil ROLF Garden 2T

The oil is produced on a synthetic base, which ensures the highest quality. Therefore, ROLF Garden 2T has low smoke, burns completely and with extremely low soot. At the same time, it reliably protects the engine from wear, since it has a balanced additive package. When the engine runs for a long time on the ROLF Garden 2T, rapid contamination of the muffler with carbon deposits and products of incomplete combustion of oil, which reduce the power of the chainsaw, is eliminated.

The oil was developed specifically for garden equipment, where the main method of lubrication is a ready-made fuel mixture. This was taken into account when creating ROLF Garden 2T, and the product achieved excellent stability when mixed with gasoline. The finished composition during storage prevents delamination and clogging of carburetor channels. The oil does not reduce the octane number of gasoline and eliminates the risk of detonation under load.

Due to its low freezing point, ROLF Garden 2T is also ideal for winter work, which maintains the efficiency of engine lubrication with the fuel mixture. The oil burns well in the engine, reducing the risk of spark plug failure. In this way, the amount of maintenance required for the chainsaw can be kept to a minimum.

The quality of the oil is confirmed by approvals from the largest chainsaw manufacturers. In addition, ROLF Lubricants GmbH offers a simple and effective anti-counterfeit system: all of the company's products are packaged only in tin containers. As practice shows, counterfeit goods are practically never found on the market under such conditions: for manufacturers of counterfeits, packaging in plastic is more profitable.

Features of running in a new tool

This concept includes a gentle operating mode of the chainsaw at the initial stage of its operation. The technology also provides for the engine to operate on a mixture with an increased content of motor oil by 20%.

The break-in time in engine hours is indicated in the attached instructions. In practice, to reach the working level of the tool, 3-5 refills of the saw’s gas tank are sufficient.

New models do not need to be broken in, but it is not recommended to use the chainsaw with heavy loads during the first hours of operation.

We service a push-pull trimmer

For a two-stroke engine, the main maintenance operation is the maintenance of the air filter. The frequency is 10 hours of operation. When cleaning, wash the material in warm soapy water. Before reinstalling the surface, lightly soak it in oil.

At the same time, check the cleanliness of the fuel filter (if equipped). However, it is better to clean the fuel mixture when refueling the trimmer. The spark plug is checked regularly for carbon deposits. The gap between the electrodes should be 0.5 mm.
