How to dilute gasoline for a Ural chainsaw

Preparation of the fuel mixture when working with the MP-5 "Ural-2T Electron"

During the running-in period of the chainsaw, use a fuel mixture of gasoline and oil according to 2.3 in a ratio of 15:1 by volume, i.e. add 1 liter of oil to 15 liters of gasoline and mix the mixture thoroughly. The amount of gasoline and oil in the fuel mixture is given in Table 1.

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 anyone who just wants to buy such a unit will find the article interesting.

A chainsaw is one of the most convenient and versatile household units. Before use, you need to prepare the fuel mixture. But in order for the unit to work correctly, you must follow all the manufacturer’s recommendations. Each model is individual, so what kind of gasoline should you put in your chainsaw?

Ratio of oil and gasoline for the fuel mixture

The proportion of oil and gasoline for a chainsaw is usually made according to two recipes:

50 servings of gasoline per serving of motor oil
40 units of gasoline per unit of motor oil

If the chainsaw was recently purchased and has not yet been used, then the proportion of lubricant is increased by a quarter. The same amount of it is poured into fuel when sawing at temperatures below +2 degrees . It is not difficult to obtain such a mixture. Almost every modern saw is equipped with a special two-section container. Oil is poured into the smaller part, and gasoline into the larger part. The lids of both parts are screwed tightly and the container is turned over and shaken thoroughly. This ensures complete and homogeneous mixing of both components.

If there is no such special container, then you can use any gasoline-resistant plastic container with a one-liter lid and a disposable syringe for 5-10 cubes . The gasoline container must first be cleaned of various types of contaminants and water. After this, one liter of 92-95 gasoline is poured into it.

20 ml
is drawn into the syringe . If refilling is done in cold weather, then you need to take 24-30 ml . Carefully pour it into the container with gasoline. It is tightly closed with a lid and shaken thoroughly until the components are completely mixed.

How much oil should be added to gasoline?

Types of oils used for dilution in gasoline
Chainsaws do not have oil pumps, so the combustible mixture alone cannot be used. You should carefully read the instructions supplied by the manufacturer with each product. There is a lot of information on the Internet, finding it is not difficult.

If there is no lubrication, the saw will fail in a short time. It is recommended to do preventive maintenance of the unit, fill with properly diluted fuel, in this case the tool will function for many years.

If we take, for example, a Husqvarna chainsaw, then unleaded gasoline with the first additive of grade 92 is suitable. If the composition has a greenish color, then this indicates that the product is “Premium”. AI-92 is the optimal product that can be suitable for such a device. On average, professionals advise adding from twenty to 50 ml of machine oil per liter. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil will be required.

How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:

Measuring liter bottle

A watering can that will allow you to pour the substance into the tank

The process of mixing oil and gasoline is technologically simple. It is important to follow safety precautions so that static electricity does not accumulate and not a drop of water gets into the fuel.

Types of oils used for dilution in gasoline

What proportions should be made? Engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws operate with products of the following brands:

For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are characterized by economical fuel consumption; the proportions of oil in them vary from 40 to 49 parts.

Oil shades can vary significantly; this should be taken into account during operation. For example, it produces reddish-colored machine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is premium synthetic. The quality of such compositions is high, and the cost is also quite high.

Recommended brands of fuels and lubricants for powering chainsaws

The specific brand of gasoline for the saw is always given in the manufacturer's instructions.
It is recommended to strictly follow it. There are 2 types of oil:

for the engine,
for lubricating the chain and bar.

Do not confuse or misuse them. This is guaranteed to lead to tool failure. Repairing it can cost almost the same as a new saw.

The most popular lubricating oils for chainsaws are the following brands:

Each container with branded oil always indicates the proportion of oil and gasoline for a chainsaw (Stil, Husqvarna, Partner, Ural), which must be adhered to when composing the mixture.

Step-by-step instructions for refueling

If you want to refuel your chainsaw, you need to follow a simple algorithm:

Prepare fuel in the recommended proportion of gasoline and oil for two-stroke chainsaws.
Prepare the saw for refueling by clearing its surface of sawdust and shavings.
Place the saw on a flat, stable stand with the reservoir neck facing up.
Carefully place a small funnel (plastic or metal, resistant to fuels and lubricants, easily purchased at an auto supply store) into the open neck of the tank.
Carefully pour fuel into the tank, avoiding overflow. It is unacceptable to pour under the lid - this will lead to splashing out while screwing the lid!
Close the lid of the fuel tank
Replace chain lube (required!)
Test run the engine at idle speed.

What happens if you pour waste into a chainsaw?

Once a chainsaw owner has been using it for a while, he may want to make some modifications to the tool. And it’s good if his desires are limited to purchasing various attachments that expand the functionality of the chainsaw. But some go further - they begin to experiment with the gasoline and oil that their saw runs on.

If we already talked about gasoline earlier (most modern saws require it with a high octane number - no lower than 92-95), then it’s worth special mention about oil. Many car enthusiasts accumulate a significant amount of used engine oil during the operation of their car. And that’s why some people want to use this material to refuel a chainsaw.

If you do this, then engine failure is guaranteed. The reason for this will primarily be the low lubricity of the reused oil. It will burn with a lot of black soot. The metal particles contained in the oil will first clog the fuel filter (these are the larger particles), and then the cylinder sealing rings will fail. Metal suspension in oil will damage both the surface of the cylinders themselves and the bearings.

Some “innovators” are trying to use oil to lubricate the chain itself and the block on which it is located. This will also not lead to anything good. What exactly will happen can be seen in the attached video.

Under the brand

For modern brands, for example, Husqvarna, Partner, Makita, Echo, Shtil, AI-92 gasoline is suitable. Today, a huge number of people complain about premature failure of chainsaws due to bad gasoline. Therefore, some experts recommend pouring AI-95 into such chainsaws. At the same time, good AI-95 can “burn the piston,” and again, a number of people have found a compromise and mix AI-95 with AI-92. In general, it all depends on the quality of gasoline and ultimately it’s up to you to decide.

For domestic instruments, Ural, Druzhba, it is recommended to take AI-80 gasoline. It is very important that fuel consumption is minimal.

The adjustment is made by changing the quality and quantity of the combustible mixture entering the engine cylinder. The amount of mixture is changed by screw 3 (Figure 1), which limits the rotation of the throttle valve control lever 1 towards its closing. The quality of the mixture is changed with screw 1 (Figure 2) of the carburetor. When adjusting engine idle speed, you should be guided by the following requirements:

Features of using a chainsaw

Rules for the use and maintenance of the Electron Ural 2t chainsaw:

for optimal functionality of the tool, use a fuel mixture in a ratio of 1:50, this is the optimal ratio for high-quality operation of a two-stroke engine;
after a break in work, use only fresh fuel mixture;
regularly check the condition of the chain and bar, make sure that the chain receives lubricant;
use high-quality fuel, high-viscosity oil and pure gasoline;
store the saw in a dry place, under a waterproof cover;
upon completion of work, clean the chainsaw body from dirt;
work only with hearing protection and cover your face with a special plastic mask;
replace fuel and air filters and spark plugs according to the instructions;
Adjust the chainsaw carburetor annually.

The carburetor is adjusted in idle mode using the adjusting screw. If the carburetor is adjusted correctly with the screw, the engine will increase speed on its own without moving the chain along the tire.

Ignition circuit for the Ural 2 Electron chainsaw

Owners of the Ural 2T Electron chainsaw may encounter the following most common tool malfunctions:

Lack of high-quality sawing, the tire moves “heavily” on wood and produces small chips.

Reason: the chain is dull and needs sharpening or replacement.

There is a strong noise, knocking, rattling when the chainsaw is operating.

Reason: the carburetor needs to be adjusted, the carburetor needs to be adjusted in the service.

The saw began to stall right during operation, or completely refused to start.

Reason: poor quality fuel, ignition problems, the spark plug may need to be replaced or cleaned of carbon deposits.

Carburetor adjustment

Adjusting the idle speed of the chainsaw engine.

a) The engine should idle steadily and the saw chain should not move along the bar.

b) There should be no strong smoke when the engine is running.

c) The engine should have good throttle response, that is, when the throttle control lever is pressed sharply, it should quickly gain speed.

d) It is recommended to adjust the idle speed in the following sequence: - start the engine and warm it up at low and medium speeds. Use screw 3 (Figure 1) to set the minimum stable speed at which the saw chain does not move along the bar. If the engine smokes heavily (a sign of an excessively rich mixture), then partially tighten screw 1 of the carburetor. At the same time, the engine speed will increase and the exhaust smoke will decrease; — after this, you should again set the minimum, stable engine speed by partially unscrewing screw 3 (Figure 1); — after this adjustment, it is necessary to check the engine response. To do this, sharply press the throttle control lever for 2-3 seconds until it stops. In this case, the engine should quickly gain momentum. If the engine stalls or has a “drop” in power, that is, it slowly picks up speed (lean mixture), then it is necessary to partially unscrew screw 1 of the carburetor. Engine speed will decrease. To increase the idle speed, screw 3 must be partially tightened. Check engine response again; — upon completion of the adjustment, secure screw 3 with locknuts 2 (Figure 1).

Operating instructions

According to the operating instructions for the chainsaw, the device must be unpreserved and assembled before carrying out work.

The gasoline-powered saw is assembled in the following sequence:

Unscrew the screw and disconnect the elements of the frame structure clamp.
The engine is installed in a vertical position on the side of the crankcase cover, the gearbox is mounted on it with a connecting flange, and the mechanisms are secured with a clamp.
The screws are installed in the grooves until they are fixed.
The handle is connected to the carburetor throttle control cable so that the gap between the elements is 15-16 mm.
Adjust the tightening of external fasteners.

How to break in a chainsaw

The chainsaw is run in first at idle, then during operation.

The operation is carried out at idle speed until 4 fills of the gas tank are fully used.

The fuel mixture is prepared in the following ratio: 1 liter of universal motor oil to 15 liters of gasoline.

Used oil is not used, otherwise the connecting rod needle bearings will fail. You should also not use leaded gasoline or fuel contaminated with mechanical impurities or water. Subsequently, the liquids are mixed according to a 20:1 ratio.

Run-in during operation is carried out during the first 25 hours, the engine is not overloaded.

Chain for chainsaw Ural-2T

For the Ural-2 Electron gasoline-powered saw, a MI-10.26 U-16 Strong chain is used.

During operation, it stretches, so the tension must be periodically adjusted using the tensioner screw. The saw chain can be easily removed and switched on and off automatically using a centrifugal friction clutch.

Sharpening is carried out with a round cylindrical file with a diameter of 5-6 mm, followed by immersion in oil for 5-10 minutes.

What kind of gasoline should I put in my chainsaw?

When choosing the right fuel, each tool owner should take into account the brand and country of origin of the model in the household. Old saws of domestic production called Ural and Druzhba are best refueled with AI-80 gasoline. It contains exactly those additives that are necessary for the stable operation of unpretentious domestic engines. More modern domestic models are designed to run on 92 gasoline.

Things are a little different with imported chainsaws. The engines of all these models are designed for more gentle fuel, so German, Swedish, American and Japanese chainsaws must be filled exclusively with AI-92 gasoline.

When choosing gasoline, its condition plays an important role. Many novice gardeners are confident that the fuel tank of the saw can be filled with fuel, which will remain in the canister for a long time. Some believe that the tool already works in conditions of constant dust, and it is because of this that manufacturers have provided a special air compensator in the carburetor, which is activated when the air filter wears out.

This opinion is fundamentally wrong. As a result of a long stay in a canister, gasoline loses its main properties, and its composition, depending on the material of the container, is replenished with molecules of plastic or metal rust.

Due to the long stay in the canister, gasoline begins to lose its vapors, which are what ignite when the chainsaw is started. It is because of this that gardeners face a number of typical problems, including:

difficulty starting the engine;
rapid drop in engine power;
accelerated wear of tool elements.

To prevent this, you need to regularly use only fresh fuel from trusted gas stations. It is best to buy 2-3 liters of gasoline every morning before starting work in the garden. Using fresh gasoline will make it easier to start the chainsaw and significantly extend its service life.

Preparing the fuel mixture for a chainsaw

Let's look at everything in order:

Petrol

Gasoline must have an octane number of at least AI92. You can also fill in AI95, but its quality at our gas stations leaves much to be desired, so if you are not sure of the quality of 95, then it is still better to take AI92 gasoline for diluting gasoline in a chainsaw. You should also not take gasoline that has been sitting for a long time in a canister, tank or any other container. Gasoline for preparing the fuel mixture for a chainsaw must be fresh, otherwise it loses its properties, in particular its octane number, and even if you run the chainsaw on such fuel, it will not produce full power. And the saddest thing in this case is that the failure of a chainsaw due to low-quality fuel is considered a non-warranty case and leads to expensive repairs. Sometimes it’s easier to buy a new chainsaw than to repair it after such a breakdown!

Oil

Oil for 2-stroke engines according to the classification of the American Petroleum Institute (API), the American Petroleum Institute has the API-TB class, there are also API-TC class oils, but they are designed to work with lower loads than most common chainsaws. If you take the power class according to the Japan Automobile Standards Organization (JASO) classification, then focus on the JASO-FB and JASO FD classes (see Table 1 below.). Do not under any circumstances use oils for four-stroke engines! Remember that in a two-stroke engine the oil must burn completely, which means it is better to take synthetic oil, since it produces less smoke and combustion residues. And if you fill your chainsaw with oil for four-stroke engines, which will not burn completely and as a result carbon deposits will form, then your CPG will fail. The best thing to guide you when choosing oil for a chainsaw is the instructions for it.

Proportions

When preparing a fuel mixture of gasoline and chainsaw oil, be sure to check the manufacturer's recommendations. Why is it so important to follow these recommended proportions? If the amount of oil in gasoline is small, the cylinder and piston will heat up and, accordingly, scuffing will occur, which means failure of the CPG and repair. If there is a lot of oil in gasoline, then this is carbon deposits and again failure. Each manufacturer has its own recommendations on proportions (see Table 2 below). Try not to store the finished mixture for more than a month. Do not store it in direct sunlight or open. Avoid ingress of water and dust - this will lead to carburetor failure, since the fuel filter is often not able to completely clean the fuel.

Since they often come from search engines with queries like “how much oil to pour into 1,2,5 liters of gasoline,” I’m adding another table under No. 3 in which you can find out how much oil to add to gasoline according to the accepted proportions. The proportions can be found in Table 2 or, more precisely, in the instructions for your chainsaw.

Devices for diluting the fuel mixture

Of course, you can use a canister, syringe or measuring bottle, but there are more convenient options. It is worth noting here that, for example, Stihl oils are available in 2 types of packaging - with and without a dispenser. With a small difference in price, a bottle with a dispenser greatly simplifies the process of preparing the mixture. There are also many different canisters with a dispenser, with separate compartments for oil and gasoline. All these devices reduce the preparation time for starting and operating the chainsaw.

Is it possible to put 95 gasoline into a chainsaw?

In almost every operating manual you can find instructions from manufacturers that for regular refueling of household tools you need to use gasoline with a constant octane rating of no higher than 92. Despite this, many novice gardeners continue to refuel their saws with 95-octane gasoline, in vain believing that he is better.

It should be remembered that the engines of all imported and some domestic instruments are initially designed to run on 92-grade gasoline. If you pour 92-octane gasoline into the fuel tank of the tool, this will cause the piston to push in the opposite direction, which is often called detonation. This dangerous process will become cyclical and will be repeated with each revolution of the internal combustion engine crankshaft. There is probably no need to say that using 98-grade gasoline will have an even worse effect on the operation of the piston and the condition of the chainsaw engine.

Good to know

Fuel must be prepared for 3 refills. After all, storing a large amount of fuel can negatively affect the operation of the chainsaw. The mixture can behave differently, because it will be influenced by many factors. As a result, your household unit may suffer serious damage, which will entail financial costs.

Sometimes even the container can affect the quality of the liquid. Plastic and glass react with gasoline, creating a flash fire hazard.

It is important to remember that if the chainsaw breaks down due to poor-quality or incorrect mixture, it will not be possible to repair the unit under warranty.

The finished liquid cannot be stored for more than a month, because the oxidation process occurs. After working with a chainsaw, you need to use up the remaining fuel, turn off the engine and remove the remaining fuel mixture.

Oil for two-stroke chainsaw engines

Modern gasoline saws can be equipped with 2-stroke or 4-stroke engines. In the latter, oil is initially supplied to the crank group parts directly from the engine crankcase.

In contrast, in two-stroke factory engines, fuel enters a plane located under the piston. To refuel such chainsaws, you need to add motor oil to fresh gasoline. It lubricates the rubbing parts of the engine, preventing their premature wear.

Oil for 2-stroke chainsaw engines must meet a number of important parameters:

When burning oil, a minimum amount of ash should be formed. It is best to allow the oil used to burn completely;
the lubricant must dissolve quickly in gasoline;
Oil for 2-stroke engines must be free of harmful impurities that can lead to blockages in the carburetor lines.

How to dilute gasoline with chainsaw oil?

The mixture of gasoline and oil must be constantly prepared in a clean container, the walls of which have measuring marks. This will give the chainsaw owner the opportunity to accurately determine the amount of gasoline and motor oil he is mixing. The material from which the container is made must be resistant to gasoline. Metal containers work well for this.

Fuel and lubricant must be poured through a watering can to prevent loss of components. In order for the lubricant used to completely dissolve in the fuel, the filled container will need to be shaken several times. As a result, the gasoline mixture should become evenly colored. In this case, you need to make sure that there is no sediment at the bottom of the vessel.

Advantages and disadvantages of oil

Any high-quality machine oil has its pros and cons.
Any high-quality engine oil has its pros and cons . Some experts say that any chainsaw oil will do. This is not entirely true; almost any substance can be used for the Khurstavna chainsaw, but only gear oil is required for the Shtil chainsaw. When choosing, you need to know the color of the oil well; a two-stroke engine requires a composition that has a reddish, bluish or greenish tint.

To prepare the mixture yourself, you need to use a heat-resistant lubricant that has a well-known brand.

The density of the product is affected by seasonality:

Solar radiation intensity.
Pressure.

what the features of different oils are by carefully studying the label on the container. If there are no instructions or labels on the package, you should refuse to use such a substance. At the same time, the performance characteristics of oils should not change dramatically when temperature conditions change.

You should not use any substitutes; counterfeit products are often found among them (up to 20%). It is quite difficult to distinguish a fake; you need special equipment.

It is recommended to store fuel in metal containers. It is best to prepare the fuel mixture in a canister.

There are a large number of oils and each has its own characteristics

The consistency is made in the ratio:

The performance characteristics of mineral or organic oil intended for the chain itself are not suitable for preparing the fuel mixture. The container is filled with the finished product (up to half), then mixed (the container must be hermetically sealed). Thus, a homogeneous composition is obtained. It is better not to prepare the fuel ahead of time; it quickly loses its functional properties. At room temperature, flammable liquids deteriorate within two weeks.

The ratio of oil and gasoline for a chainsaw

Every chainsaw company tunes their engines and base carburetors to run with different amounts of lubrication. Therefore, the proportion of oil and gasoline for a chainsaw may be slightly different.

Most often, when mixing fuel with oil, manufacturers advise using proportions of 1:50 or 1:40. This means that 1 part of motor lubricant must be mixed with 50 or 40 parts of fuel, respectively.

Translating the proportion into a more accessible formulation is quite simple. For example, 1 liter of fuel contains 1000 ml. If you divide 1000 ml by 40, you get 25 ml. This means that for 1 liter of gasoline you will need to dilute 25 ml of lubricant. The same formula should be used when the manufacturer recommends preparing the fuel mixture exclusively in a ratio of 1:50. To do this, 1000 ml must be divided by 50, resulting in 20 ml. This means that 20 ml of motor lubricant should be diluted in one liter of fuel.

Things are a little different with Chinese chainsaws. Their manufacturers advise diluting gasoline for chainsaws in a ratio of 1:25. This means that owners of Chinese tools need to mix exactly 40 ml of lubricant into 1 liter of pure gasoline. This ratio is due to the fact that in terms of build quality and selection of components, these chainsaws are slightly inferior to their Western counterparts. In engines of American, European and Japanese models, the distance between the cylinders and pistons is significantly less than that of chainsaws from China. In this regard, the amount of lubricant required for the operation of the former. far less.

Fuel consumption

One of the most important questions that arises among owners of saw tools, because everyone wants to know what to expect.

The volume of almost all tanks is approximately 500 ml. If the power of the chainsaw is 2 kW, then the consumption of the fuel mixture will be approximately 1.2 liters per hour of operation. To put it simply, such a tool will be able to work at maximum speed for half an hour without a break. If the chainsaw is not so powerful, then its tank volume will be smaller. This way the user can independently control fuel consumption.

Over time, the user will learn to service his tool without any help. The main task will be to maintain the economic unit in good working condition, using high-quality fuel mixtures. Follow safety rules when preparing flammable liquids. This will help preserve the instrument and not harm yourself and the environment.

What oil should I use for a chainsaw chain?

To find out exactly what oil to use to lubricate the chainsaw chain, you will need to study the instructions of its manufacturer. Almost all tool manufacturing companies recommend using a product that has the highest adhesive properties. This means that the material used to lubricate the chain must have adhesion to the metal surfaces of the chain and bar.

You need to figure out why a lubricant has adhesive properties. While the chain moves along the standard guide bar, the saw element reaches high speed. If you use chainsaw oil with low adhesion for lubrication, then more than half of the liquid will fly off from the top of the tire by inertia, never reaching its bottom. As a result, such oil will prove to be ineffective, and the tire and chain will quickly fail due to constant friction.

Chainsaw device

Each chainsaw has different technical specifications and can perform different jobs.
Powerful saws are suitable for felling centuries-old trees; small chainsaws are more suitable for performing various tasks in the household:

Standard chainsaw blocks:

Power point.
Clutch.
Ignition unit.
Carburetor.
Fuel block (tank for oil and fuel).
Filters for cleaning incoming air.
Starter.
Chain.
Tire.
Chain brake.
Tension mechanism.
Element that provides chain lubrication.

Each chainsaw requires high-quality fuels and lubricants; they ensure long-term productive operation of the unit. What kind of gasoline should I fill in for a chainsaw, in what proportions?

For domestic chainsaws, simple oils are suitable; foreign chainsaws need more complex fuel mixtures that have been thoroughly cleaned.

The best oils for chainsaw chains

You can find the highest quality oils on the market, which are recommended to be used by almost all manufacturers of chainsaws and companies that manufacture saw accessories for them. These products have high adhesive properties, which makes them effective when working in difficult weather conditions. These lubricants include:

Stihl ForestPlus oil - this composition is best used at an air temperature of at least -15 ⁰ͦC. The material is supplied for sale in containers with a capacity of 1 or 5 liters;
Stihl SynthPlus lubricant - has high adhesion to metal coatings. The composition shows high efficiency when working in conditions not lower than -25 ⁰C;
Husqvarna Bio Advanced oil performs equally well in both normal and extreme conditions. The product has a balanced composition with increased adhesive properties;
Makita Biotop lubricant is one of the top products. reliably protecting the sawing parts of the tool from increased friction and premature wear. The price of this oil is an order of magnitude lower than Stihl products;
Oleo-Mac Polar Lube oil is a budget lubricant that stands out for its low price and excellent viscosity and adhesion parameters.

To lubricate each of these products, manufacturers advise using no more than 5 mg of lubricant per cycle of operation.

Description

Chainsaws "Ural" are products of a Russian machine-building plant located in the city of Perm. Currently, production has been moved to the city of Biysk. The Ural chainsaw is a kind of improved version of the Druzhba chainsaw, which was very popular several decades ago. Now Druzhba chainsaws are used more for domestic purposes, while Ural saws are produced for professional purposes.

Photo of the Friendship chainsaw

The first Ural chainsaw was released in 1935, since then the manufacturer’s product range has expanded significantly, the range of chainsaws is represented by both household and professional models with two-stroke gasoline engines. The advantages of Ural chainsaws over domestic analogues are the following technical characteristics:

the ability to work for a long time on fuel of any quality (even medium-purified gasoline is suitable);
omnivorous oils (any oil is suitable for 2T gasoline engines);
large selection of spare parts and their reasonable cost;
easy setup of the chainsaw;
availability of models for specific tasks (household, professional, semi-professional);
powerful motors, the ability to withstand intense loads, operation at any time of the year at any temperature.

Chainsaw Ural 2T Electron
The purpose of Ural chainsaws is very wide: tools of this category are successfully used in sawmills, sawmills, logging industries, in everyday life, and for municipal needs. Suitable for remodeling, can be used as a technique for harvesting firewood, cutting boards and beams. Another area of exploitation: construction of wooden houses, baths, saunas, cottages.

Chainsaw Ural 2T Electron is a saw for professional use. Equipped with a gasoline engine with a power of 5.5 horsepower. This power is equivalent to 4045 W. The saw is used for working with large-diameter trees, for harvesting wood, and for felling trees. Owners of the Ural 2T Electron chainsaw often talk about the possibility of converting this tool into a more universal one, for example, the Ural 2T Electron is often converted into a boat motor.

Chainsaw Ural 2T

This “second life” for the device is made possible thanks to the sustainability of the materials, high power and functionality of the device. Some owners even install a 2T Electron motor on a moped or snowmobile, or a household snow blower. The technical characteristics of the engine are such that it operates successfully in both cold and wet weather. Such homemade units, according to reviews from owners, are in no way inferior to the original equipment.

Chainsaw sprocket oil - manufacturer's advice

In order to reduce friction on the drive sprocket and extend the service life of the mechanism, each manufacturer equips it with a needle bearing that requires periodic lubrication. Many experts advise using a multi-purpose composition from the Stihl brand for this.

This product is quite expensive, so some gardeners and professional forest fellers use lubricants at a lower cost. Compositions such as Litol or Litol 24 have proven to be effective against increased friction of a needle bearing.

To lubricate the driven chainsaw sprocket, as well as to protect the drive sprocket, you can use the same oils. A small syringe is suitable for applying them. It quickly presses lubricant into small holes in the tire and near the bearing located above the sprocket.
