Purpose of the oil • Useful tips

respectively, the fuel tank, the engine and the working body, which does the work itself, as well as other articulated bodies that help in control. There are also references to AI-95 gasoline, but it is less popular because it is more expensive and contains a larger amount of methyl tert-butyl ether, an additive that reduces the risk of fuel detonation.

Is it so . (he said warily) what oil is suitable for the chain?? VladlenPopolitov (Khimki) May 25, 200412:59:21 Any automobile mineral oil is better than waste oil, and waste oil is better than sawing without oil at all. Since automobile oil is chosen for chain lubrication for reasons of cheapness, you need to choose the cheapest one, since the price automobile oils depend on additives that allow the car engine to start and operate either in cold weather or at elevated temperatures, which has nothing to do with your case. In the end, using oil to lubricate the chain is not a strict requirement of the manufacturer, but simply an opportunity for client to buy a saw and everything that comes with it in one place, without running around looking for files, lubricant, and wrenches.

Operating Instructions © Maintenance

1. If fuel is used that is stored for a long period, this will negatively affect the traction characteristics of the internal combustion engine. In addition, such operation causes small detonations, as well as the appearance of carbon deposits.
2. All chainsaw users should not pay attention to low-octane mixtures, as they are characterized by low quality.
3. In some cases, leaded fuel can be used. It can significantly extend the life of the device.

Be careful - counterfeit! • Thus, 1 liter of fuel consumes no more than 20 ml of oil.

Requirements for the fuel used

The first question that arises when using a chainsaw is choosing the most suitable fuel. Experts recommend carefully choosing gasoline for a chainsaw, since if the substance is of poor quality, the structure of the internal combustion engine may be damaged. Unleaded petrol is often chosen as it is highly compliant with established standards. The exact brand is indicated by the chainsaw manufacturer in the operating instructions. That is why problems with choosing the most suitable composition should not arise.

The use of fuel that does not meet the basic parameters leads to the following problems:

1. The power rating may be significantly reduced.
2. Power can jump over a fairly large range.
3. The engine will begin to overheat when the recommended octane number is exceeded. Too high a temperature can cause the material's ductility to increase and the structure to fail under high loads.

In addition, it is strictly forbidden to mix the gasoline mixture with other dubious compounds. Foreign impurities can cause damage to the structure of the chainsaw engine. When choosing fuel, it is worth considering that in addition to the octane number, the main parameters are influenced by many other parameters that need to be considered.

Refueling a chainsaw

It is also not recommended to purchase large quantities of fuel for storage. Over a long period, the basic properties may change. In winter conditions, problems with starting the engine may occur.

Application of fuel consumption standards for special equipment (lawn mowers, chainsaws, generators)

How to apply fuel consumption standards for special equipment (lawn mowers, chainsaws, generators, etc.)?

In accordance with subclause 1.2 of clause 1 of Article 171 of the Tax Code of the Republic of Belarus (hereinafter referred to as the Tax Code), standard costs include the costs of paying for the cost of fuel and energy resources spent within the limits established in accordance with the law.

The Council of Ministers of the Republic of Belarus, within the powers granted by the Law of the Republic of Belarus dated 01/08/2015 No. 239-3 “On Energy Saving”, makes a decision on rationing, by adopting acts of legislation, fuel consumption for motor vehicles, ships, machines, mechanisms, equipment in transport activities and others named cases.

Consequently, fuel rationing at the legislative level is carried out in cases where the procedure for developing, establishing and revising standards by adopting the appropriate regulatory legal act is established by the Council of Ministers. In the absence of an instruction from the Council of Ministers to adopt the relevant normative legal act, the norms are determined independently.

Taking into account the above, until 2022, when calculating profit tax in the costs taken into account when taxing profits, the organization has the right to include the cost of fuel for the specified special equipment, consumed within the limits established by the head of the organization independently, in the absence of an indication from the Council of Ministers of the Republic of Belarus on the need to establish fuel consumption standards for machinery, mechanisms and equipment at the legislative level by adopting the appropriate regulatory legal act.

The specified procedure for taking into account the cost of fuel and energy resources when taxing profits is set out in the letter of the Ministry of Transport and Communications of the Republic of Belarus, the Ministry of Taxes and Duties of the Republic of Belarus dated November 19, 2019 No. 08-02/10583/2-2-10/02529 “On some issues fuel rationing."

From 01/01/2020, in accordance with paragraph 6 of the Decree of the President of the Republic of Belarus dated December 31, 2019 No. 503 “On Taxation” (hereinafter referred to as the Decree), the costs of paying for the cost of fuel for motor vehicles, ships, machines, mechanisms and equipment consumed in within the limits of the standards established by the head of the organization independently or by contacting an accredited testing laboratory, are included in the standardized costs.

Thus, at present, on the basis of paragraph 6 of the Decree, organizations have the right to include in the standardized costs when calculating income tax the cost of fuel for the special equipment specified in the question, spent within the limits established by the head of the organization.

Additionally, please note that the Order of the Ministry of Transport dated September 10, 2012 No. 467-Ts contains fuel consumption standards for chainsaws, chainsaws, lawn mowers, brush cutters, loppers, etc., which can be used as a guide when establishing fuel consumption standards for special equipment by the head of the organization.

That is why when operating a chainsaw, care should be taken to ensure that the breather does not become dirty. Very often, a primer is installed during the manufacture of a structure. This makes starting the engine much easier.

The design features of such an element determine that fuel enters the carburetor in advance. Requirements for the fuel used The first question that arises when using a chainsaw is choosing the most suitable fuel. Experts recommend carefully choosing gasoline for a chainsaw, since if the substance is of poor quality, the structure of the internal combustion engine may be damaged.

If you are faced with the goal that the Shtil-180 chainsaw will not start, then if you figure it out, you will understand that the tool will start from a cool state without effort.

Features of running in a new tool

When purchasing and refueling a new device, a fairly large number of different factors should be taken into account. An example is that a gentle mode is selected at the initial stage of starting the chainsaw. Other features include the following:

1. The tool is filled with a mixture that contains 20% more oil. A higher concentration may cause the composition to not burn completely. Therefore, dosage must be carried out with high precision.
2. The break-in time is indicated by the manufacturer in the operating instructions.

Running in a new chainsaw

As practice shows, to fully break in the tool, only 3-5 refills of the chainsaw are enough, after which it can be used for full work. Some modern foreign models no longer require running-in. However, it is not recommended to use them immediately under high load.

Maintenance • Fuel Consumption Rates for the Stihl 180 Chainsaw.

Gas tank

You can accurately determine its value by measuring the length of time during which the truck crosses the pavement and increases the maximum load. The fuel consumption standards for operating machines do not include fuel consumption for major repairs of machines, including delivery under its own power to the place of major repairs of the machine and back to the consumer, testing and running-in of overhauled components of the machine, running-in of the machine after a major overhaul before putting it into operation, fuel losses during storage and transportation of petroleum products and for other repair and maintenance needs not directly related to the implementation of the technological process.

Chainsaw consumes a lot of gasoline

A gasoline lawn mower is not uncommon nowadays, and you can find it in almost every household plot. There is nothing special about its design, and even a beginner can use it. However, there are points that you should pay special attention to. For example, do you know what the rate of gasoline consumption for a lawn mower should be, and what values ​​does this figure depend on? If not, this article will serve as a very useful source of information for you.

So, first, let's find out what determines the gas mileage of a lawn mower. Several points are important here:

Power. Features of the engine design (two- or four-stroke). Cutting width. Area of ​​the site and its relief. Let's talk in more detail about each of the factors.

Do you want mileage of your lawn mower to be as low as possible? Take a closer look at units with a 4-stroke engine, such as the Huter GLM-5.0. Such a model is more expensive than with a 2-stroke engine, but the economical fuel consumption will significantly cover all the costs of your budget.

When purchasing a lawn mower, keep in mind that most of them are designed for smooth surfaces. Therefore, if there are uneven areas on your site, make sure that your new garden assistant has large wheels that would provide it with good maneuverability. Thus, the device will not have to work hard and waste a lot of fuel.

It should be noted that for areas with difficult terrain, it is better to purchase a front-wheel drive lawn mower, which is endowed with the best maneuverability.

Both indicators are closely related. The higher the power, the wider the cutting width. Please make sure that in the model you are interested in, these concepts are correctly balanced. Accordingly, the larger the mowing width, the less time you will spend mowing the lawn, and the gas consumption for the lawn mower in this case will not exceed the norm.

In addition, all cutting parts will not be subjected to heavy loads, which will significantly increase their service life. Let us remind you that all repairs and sharpening of cutting parts must be carried out only by a specialist in the service department.

Gasoline consumption rate for a lawn mower

Let us consider, as an example, several indicators for well-known models. For a lawn mower like the Al-ko Silver 520BR, equipped with a Briggs Stratton engine (3.7), the norm is 1 l/machine hour. For Honda HRX 426C SDE with a powerful Honda GCV-160 (4.1) engine – 0.8 tank l/machine-hour.

To ensure that your lawn mower lasts a long time and is economical in fuel consumption, we suggest that you familiarize yourself with several rules for storing this unit.

A gasoline engine is a complex structure that requires special attention and regular maintenance. Therefore, before starting work, you must familiarize yourself with the operating rules of the machine and follow the manufacturer’s recommendations.

Keep the inside surface of the case clean. Grass juice is very caustic, so after work, don’t be lazy and clean your technological assistant. When purchasing a mower, take care of where it is stored. Consider the dimensions of the unit and look for a model with a folding handle, which will be ideally located in storage.

High consumption of gasoline, where to start so that it does not consume gasoline?

Rules for preparing the fuel mixture

If you wish, you can create the mixture in question with your own hands. It is recommended to do this before using the chainsaw directly. Storing the finished substance for more than 10 days leads to the formation of a chemical bond between the additives, which reduces the service life of the engine. Experts recommend that before storing the chainsaw for long-term storage, drain the fuel and use up the remaining fuel at idle speed.

Proportions should be selected in accordance with the recommendations of the manufacturer of the device itself. Depending on the model and its technical characteristics, the indicator can vary from 1:20 to 1:100 or more.

Chainsaw fuel mixture

When mixing active elements, it is strictly forbidden to use waste or oil that is not intended for operation of a two-stroke engine.

How is mixing done?

You also need to pay quite a lot of attention to the direct process of mixing the components used. As a rule, the fuel mixture is prepared in a volume that will be sufficient for 3-4 refills of the device used. The mixing procedure can only be carried out using measuring containers.

Among the features of the issue under consideration, the following points should be noted:

1. Some chainsaw manufacturers include measuring cups with marks for fuel and oil in the delivery package.
2. If you don’t have a special container, you can use a canister or dry bottle. It is convenient to dosage using a regular syringe without a needle.

After adding all the ingredients into one container, you can begin directly mixing the components. To do this, the container is closed with a lid and then shaken to obtain a homogeneous substance.

Working proportions of the fuel mixture

As previously noted, the proportions of oil and gasoline for a chainsaw can differ significantly, largely depending on the features of the design itself. An example of mixing is the proportions 40:1 and 50:1. This ratio ensures high-quality lubrication of the internal elements of the installed engine.

In some cases, the lubricant concentration can be adjusted upward, resulting in more effective lubrication. An example is the case when a new tool is being processed. In addition, the cooling efficiency of the structure can also be increased by adding a large amount of oil to the mixture. Experts recommend increasing the oil concentration by no more than 20% of the usual value.

As practice shows, in most cases the sawyer himself has to adjust the concentration of oil in the fuel depending on the characteristics of the work being carried out. This is due to the fact that as the structure wears out, serious damage can occur. With normal operating characteristics, sawing can be carried out over a long period.

Measuring containers

Various containers with marked markings can be used as a measuring container. Controlling the ratio is simplified when using a proprietary container, which is included in the package.

It is worth considering that measuring utensils are included in the factory kit even for budget models. However, a regular syringe with increased capacity also performs well.

Storage recommendations

It is not recommended to save time and mix the composition directly in the chainsaw tank. This is due to the fact that achieving the required result will be quite difficult. Storage recommendations are as follows:

1. The resulting mixture can be stored for no more than 2 weeks. As the ambient temperature increases, the shelf life decreases to 10 days.
2. In some cases, in order to save money, a previously prepared and expired mixture is added to a new one. However, its concentration should be no more than 10%.

Storing homemade mixture

To prolong the operation of the fuel system, it is recommended to filter the composition through a material represented by fibers.

Catalyst

In order to carry out a real high-quality restoration of the working condition of the Shtil chainsaw with your own hands, you need to accurately establish the preconditions for the breakdown. The collection of standards for the consumption of fuels and lubricants for mechanized work performed in forestry includes individual consumption standards for fuel and lubricants for the main types of work: silvicultural work in nurseries, uprooting stumps in clearings with tractor units, continuous tillage for forest crops, nurseries and agricultural crops, sowing and planting forests, agrotechnical and silvicultural care; forest protection work: spraying, pollination and aerosol treatment of forest crops; forestry work, thinning in young forests, during thinning, through-cutting and sanitary felling, wood skidding; irrigation and forest drainage work, road construction, work on preparing routes for a forest drainage network, work on installing a forest drainage network on a prepared route; fire prevention measures; transport work.

Adjusting the carburetor of the Shtil 180 chainsaw with your own hands. Purpose of the chainsaw

1. First, the operator must assemble the saw and install the cutting set on it. It is impossible to run in a tool without a tire and chain, since all its components, including the cutting parts, must undergo preparation;
2. After filling the saw with a fuel mixture prepared in accordance with the manufacturer’s instructions, you need to start its engine and leave it running until the first fuel tank is completely used up. In this case, the operator must make short presses on the gas lever at intervals of 45–60 seconds;
3. Next, you will need to re-thread the saw and start cutting small wood. During work, you need to take 10-minute breaks at intervals of 20–25 minutes;
4. After the second tank is used up, you need to re-thread the saw and start cutting medium-sized wood.

Impression of the availability of official information

Recommended sequence

In accordance with the standard technology for preparing the fuel mixture, the calculated amount of oil is poured into a tank half filled.

The mixture is thoroughly mixed with the plug closed, after which the remaining gasoline is poured. This sequence contributes to the homogeneity of the resulting composition.

It is advisable to prepare fuel for a chainsaw in quantities sufficient to perform one-time work. The finished composition can be stored at a standard temperature of 20°C for no more than one month. At higher temperatures, the shelf life is reduced to 2 weeks.

An expired mixture initiates the formation of resinous compounds, which contribute to clogging of the jets, the formation of carbon deposits and limiting the mobility of the piston rings. In order to save money, the overexposed composition can be consumed by adding up to 15-20% of the total volume to the fresh mixture.

Gasoline engine design for chain saws

Chainsaws, like most other similar equipment, use two-stroke internal combustion engines.

Their main advantage over four-stroke engines that are used in cars is the fact that for 2-stroke engines it is possible to produce one and a half times more power with the same volume.

But there are also disadvantages - chainsaw oil must be added directly to the fuel tank, which increases oil consumption. As a result, the mixture of oil and gasoline, when burned in the working chamber, turns into oil mist, which settles on the cylinder walls and lubricates the elements of the connecting rod and piston group.

Oil for 2-stroke chainsaw engines is diluted in a certain proportion with gasoline and poured into the tank. When the gasoline in the tank runs out, it is necessary to prepare a new mixture. However, you cannot use car oil in a chainsaw - special oil for two-stroke engines is required.

Why doesn't oil flow to the chainsaw chain?

If oil does not flow to the chainsaw chain at all, it means either the oil pump drive itself has failed, or there are problems with air leaks.

Oil pump failure. If, when the oil pump plunger adjustment screw is unscrewed, oil is still not supplied to the chainsaw chain, then the drive, which is a plastic ring with grooves, has broken down. Over time, the grooves can wear out and the drive will fail, after which it will simply have to be replaced. The hose that supplies pressurized oil to the chain has collapsed or worn out. You need to re-attach it to the fitting or replace it. The grooves through which oil is supplied to the chainsaw chain are clogged - this is the most common occurrence. They need to be cleaned, after which the supply will resume.

Criteria for choosing engine oil

To independently prepare a flammable mixture, use the heat-resistant branded motor oil recommended by the manufacturer in measured quantities.

• The specificity of this lubricant is its use in high-speed air-cooled internal combustion engines, which are equipped with household and professional-class chainsaws.
• Depending on the season, motor oil of different densities is used to prepare the combustible mixture, which retains its operating properties in the temperature range indicated on the label.
• Branded oils are recommended for use, providing complete lubrication of the piston group and connecting rod and crank mechanism in all operating modes of the power unit.
• Branded products differ in color. In particular, Shtilevsky mineral oils are red, while synthetic oils are colored green. Husqvarna branded motor oils are blue or green.

Even taking into account the lower cost of mineral oils, it is recommended to take advantage of the advantages of synthetic analogues to prepare a high-quality fuel mixture.

Summing up

In order for your chainsaw to serve for many years, never fill it with old gasoline, and you don’t need to use grade 95, much less 98, gasoline to prepare the fuel mixture, only 92. Also, don’t forget about the purity of the gasoline—no dressing up!

I hope now you are not wondering which gasoline is suitable for a chainsaw and which is not so good.

What kind of oil to put in a chainsaw?

Manufacturers themselves do not produce lubricants, with rare exceptions, but they cooperate with all well-known brands and often offer their products under their own label.

Therefore, in the passport you will definitely find a mention of which 2-stroke chainsaw oil is suitable for this specific model.

Additional functionality

The Shtil 250 petrol saw has many advantages, namely an anti-vibration system that effectively protects the user, this is especially important during long and complex work. Among other things, it guarantees the most comfortable work possible. The master will be able to tension the chain without touching it, which is possible thanks to the side device. It is impossible not to note a positive feature, which is expressed in the presence of one lever, with its help the operator will be able to control all elements of the unit. “Shtil 250” will not let you down even in the coldest weather, since the manufacturer has taken care of preheating the carburetor; with this functionality you can work at any time of the year.

Advantages and disadvantages

For private work, the tool shows good performance. The saw becomes a reliable assistant in woodworking, felling trees and removing excess branches. The model proved to be excellent in the construction of log houses and the arrangement of landscape elements made of wood.

The main advantages of the model:

1. Price/performance ratio.
2. Reliable mechanisms, durable materials, a minimum of elements that can break.
3. Ergonomic handle shape. High-quality balancing of the body.
4. Well designed levers and control system.

What kind of gasoline should be poured into a chainsaw?

Hello! I am glad to see you again, dear readers and subscribers of Andrey Noak’s Blog. Anyone who has a chainsaw at home already knows exactly what kind of gasoline and how to fill it. But for those who just want to purchase such a unit for themselves, the article will seem interesting.

A chainsaw is one of the most comfortable and versatile household appliances. Before use, it is necessary to prepare the fuel mixture. But for the unit to work correctly, you must follow all the manufacturer’s advice. Any model is personal, so what kind of gasoline should you put in your chainsaw?

Under the brand

For modern brands, for example, Husqvarna, Partner, Makita, Echo, Shtil, AI-92 gasoline is suitable. Now a colossal number of people are complaining about the early failure of chainsaws due to disgusting gasoline. how to reduce oil consumption of an old chain consumes 1 tank of chain lubrication oil for 6-8 tanks of fuel. That’s why some experts advise pouring AI-95 into such chainsaws. At the same time, a good AI-95 can “burn the piston,” and again, a certain number of people have found a compromise and combine AI-95 with AI-92. In general, everything depends on the properties of gasoline and in the end it’s up to you to decide.
