A chainsaw of an Echo what gasoline is to fill. Choosing a brand of gasoline for trimmers

Gasoline for an Echo chainsaw

In the configuration of each such tool, there is a measured container, the marks on which will help in compliance with the correct proportion of oil and gasoline. Each manufacturer offers a certain ratio of fuel with oil for two.Stroke engines, but in most cases the average value is 50: 1 (50 parts of gasoline per part of the oil).

Accurate proportions are indicated in the instructions for the tool and are an individual characteristic for each tool manufacturer.

An increased amount of lubrication can lead to the formation of a carbon felted, and its deficiency will over time lead to the formation of bully on the surface of the cylinders. Each of these cases entails the failure of the CPG (cylinder-piston group).

The owner must remember not only expensive and prolonged repair in case of failure of the chainsaw engine due to non-compliance with proportions. The negative point is that service centers do not recognize such breakdowns with a warranty case, which means that you will have to pay for repairs from your

To ensure the process of making fuel, three components will be needed:

Two.Stroke oil for chainsaw. Such liquids can have several chemical foundations. Mineral, semi.Synthetic and synthetic. The cheapest and most relevant option is to pour mineral oil in a chainsaw. The properties of this fluid are sufficient to provide an appropriate lubricant effect during operation.

The only disadvantage is the inability of operation in the cold. Even at small negative temperatures, the oil thickens, which, in the end, negatively affects the resource of the engine of gasoline saw. Given the fact that working with a similar tool is carried out mainly in the warm season, a mineral.Based liquid remains the best option.

Semi.Synthetic and synthetic oil is also recommended to add to gasoline. If work with a chainsaw is carried out all year round, then fluids of this type will become a preferred option, otherwise sudden cold can be found by surprise. The properties of these oils allow you to withstand low temperatures without changing viscosity.

The difference in cost with mineral water is about 50 rubles per 1 liter. Semi.Synthetics and synthetics are distinguished by the blue color of the liquid, while mineral oil is red.

Fuel. If for domestic production (Ural, friendship) it was allowed to use gasoline of the AI-76, AI-80 brands, then modern foreign analogues require fuel with a higher octane number-from AI-92 and above.

How to fix a leaking gas tank

Capacity. To comply with the exact ratio of oil and gasoline, the presence of two clean and dry containers is required. In one of them, with volume marks, a two.Stroke lubricating fluid is added.

In another. Fuel. Having measured a liter of gasoline, it is necessary to mix it with twenty milligrams of oil.

ECHO CS 310 Gas Chainsaw Overview

Thoroughly shaking the substance, some part of it can be poured into a measured container in order to wash the remnants of the oil. After that, everything again merges into one container.

Above has already stated that the incorrect ratio of two components can lead to a serious breakdown of the chainsaw. Oil manufacturers took this important point, releasing a container with a dispenser, which allows you not to resort to the use of a separate container. The surcharge in the case of buying such a bottle will be small (20-30 rubles).

Gasoline for a chainsaw

For domestic chainsaws (Ural, friendship, etc.) AI-80 gasoline is used. Oils can be used domestic, such as M8-V (or early marking AS-8.10), M-12 TP, M-12TPU, MGD-14M. It is also possible to use oils from imported manufacturers. In any case, the proportions when mixing oil and gasoline should be 1/25, that is, one hundred grams per two and a half liters of gasoline. For modern chainsaws from imported manufacturers, the proportions are usually 1/40 (100 grams per 4 liters of AI-92), 1/50 (100 grams per 5 liters of AI-92). Gasoline use AI-92 brands. You can often see that the AI-95 brand will be indicated in the instructions. But with our quality of this gasoline, the octane number of which is catching up with additives, I would not recommend using the 95th if you are not sure of its quality.

Read more about the proportions of the preparation of the mixture:

To measure the required amount of oil, you can use a syringe, a measured bottle, a special dispenser, or, for example, a bottle with a dispenser from STIHL. Oils from different manufacturers of different colors. As you can see in the figure above, the Stilevsky oil of the HP brand (mineral water) is red, more expensive synthetic green. Huskvarna oil can be green or blue.

Remember! In the case of a chainsaw fails due to the pouring of the wrong mixture, the repair will be unlawenty!

[important] Adviсe: It is better to pour oils than underdraw! If 1/50 is written, then when you pour 25 grams per liter of terrible, since the clinic in this case is unlikely. But if you add 15 grams per liter, it is quite possible that this will not be enough. Do not store the finished fuel mixture for more than a month (better less), since it loses the octane number (gasoline “exhales”). Before the season, produce the entire tank to the end or drain to avoid loss of the quality of gasoline and wear of rubber and plastic seals. In no case do not use moped oils are designed for lower speeds [/important]

Basil: questions and answers

Today I answer the questions that they ask, as well as the search queries for which people come to the blog from search engines.

Question: “What kind of oil to pour into the Echo chainsaw?”” “What oil to fill in the Solo chainsaw?”” “What kind of oil to pour into the macita chainsaw?”” The question is also very often asked: “And if I fill the Husqvarna (Solo, Prorab, Makita and other) oil or any other branded chainsaw, then 1:25 proportions must be observed as indicated in the instructions?””

Answer: Combined these questions into one, although in fact the recommendations are suitable for all modern saws. If you fill corporate oil for two.Stroke engines, then which manufacturer does not affect. Oils STIHL, Husqvarna, Echo and other well-known brands are interchangeable, and the recommendations of the manufacturer, they say, de “our best” only marketing. So you can safely pour Husqvarna oil into the STIHL chainsaw and, on the contrary, observing the proportions as for branded oils.

[NOTE] I recommend purchasing oils of well.Known manufacturers such as STIHL, Oregon, Makita, Husqvarna, Echo and other famous brands. [/Note]

Question: “Why does the candle fill the fuel on the chainsaw?””

Answer: In 90% of cases, the reason for the carburetor settings. Too rich the mixture is formed and, accordingly, throws the candle. Carburetor adjustment is required.

Question: “Why fuel (gasoline) enters the crankcase?””

Answer: one.Carburetor malfunctions. A needle valve may be faulty and then gasoline flows into the crankcase through the inlet channel. 2.Rings. Rings can be stuck or due to wear. 3.Gaskets

Question:“What will happen if pure gasoline is poured into the chainsaw?””

Answer: CPG will fail (cylinder-piston group). Since a separate lubrication system is not provided in two.Stroke engines used on the chainsaws, the lubricant occurs due to the presence of oil in the fuel mixture. Which lubricates the cylinder and bearings of a crooked-shaped mechanism. If pure gasoline is flooded, then the lubricant does not come to the nodes and accordingly guaranteed the bullying.

Question: “Why is a chainsaw saw crookedly, that is, it takes it to the side?””

Answer: one. He led the tire. When working, do not forget to turn the tire! In this case, only replacement. 2.Uneven wear of the chain. It may occur with improper sharpening or when the chain enters (not Duro) on metal objects (nails, brackets, etc

Chain saw Echo version CS-350WES

Echo CS-350WES chainsaw is a professional tool for household needs. It can be used both for sawing building materials, cuts of knots and branches, and for rolling small trees in the garden or country house. Competent weight distribution of the body, ergonomic handles and a system of anti.Vibrational extinguishing allow the user to work comfortably for a long time. The chainsaw is equipped with a two.Stroke engine with a working volume of 35.8 cm 3 and air cooling. The power of the tool is 1.48 kW, due to which the maximum speed of rotation of the chain reaches 13500 rpm.

The chainsaw of an Echo 350 by the electronic ignition of CDI and the Light Start system with a primer is launched. To quickly launch a saw with a cold engine, there is a pen on the case that controls the air fuel mixture flap to the carburetor. Just like the previous tool model, the chain is lubricated automatically, but there is the possibility of regulating the intensity of its supply. With maximum load, fuel consumption in 1 hour leaves 1.12 liters. For safety, the saw is equipped with a protective shield in front of the handle and the inertial brake of the saw chain. The chain tension is carried out using a side control screw.

Technical characteristics of the Echo chain of the CS-350WES version:

  • The length of the saw surface is 40, 30 and 35 cm;
  • The step of the saw chain is 9.53 mm;
  • The capacity of the tank for oil, lubricating the chain. 230 ml;
  • The capacity of the fuel capacity is 370 ml;
  • Dimensions (DHSHHV). 39.2×23.3×24.2 cm;
  • Sound power level. 110 dB.

The weight of the CS-350WES chain saw is 3.6 kg, but without taking into account the saw chain, tires, and consumables (gasoline and oil). So that the gas trigger is not by chance, there is a block on the tool. To protect the hands from the torn or flying circuit, a chain capture and a protective shield of the rear handle are installed on the saw. On the muffler of the Echo CS-350WES-14 chainsaw, a casing is provided, which protects the user from random burn when contacting him.

Both models of Echo chainsaw are easily controlled and suitable for both a beginner and a professional. The main thing is to comply with all the safety rules during the use of the tool and timely maintain its maintenance. Then the chain saw will last as long as possible, and work with it will always give pleasure.

We fill the tank with chain oil and check the serviceability of the oil pump

The tank for oil should be poured exclusively by a special chain lubricant. After refueling the tool with oil, you can start the engine, and make sure that the oil pump is working. To do this is quite simple, for which it is necessary to put a blank sheet of paper from the end side of the tire. After the engine is launched, and with an increase in speed, the chain will rotate, and oily spots should appear on the paper indicating the normal supply of chain oil to the tool tire.

So that the procedure for running the chainsaws passes with maximum efficiency, you will need to purchase a tachometer. This device is needed in order to measure the number of speeds of the crankshaft during the operation of the internal combustion engine. This device will be needed not only to configure the tool carburetor before it before it, but also during the operation of the chainsaw. The principle of tuning the carburetor before the tooling of the tool is that it is necessary to reduce the number of maximum revolutions by 600-700 rpm. The maximum revolutions reaches 12.5 thousand rpm, but their achievement during the running.In is extremely dangerous. In addition, a decrease in maximum revolutions helps to enrich the mixture with fuel, which positively affects the grinding of parts.

Interesting to know! The procedure for adjusting the carburetor before rolling the chainsaw is not at all mandatory, since such actions are performed at the factory after assembling the tool. For 3-4 hours, the chainsaws are tested, for which high speeds are reduced by moving the screws h and l. If the technical documentation from the manufacturer does not say about the need to configure the carburetor, then you can carry out such manipulations only at your discretion. In any case, with the correct setting of the carburetor, this will only be an additional advantage.

The tachometer is connected to the tool, and proceed to adjust the carburetor, enriching the mixture. There is a special screw on the carburetor h for this. It allows you to increase or decrease high speed. Rotating the screw h, it is necessary to achieve the value of the testimony by the tachometer by 600-700 revolutions a minute below the maximum value, that is, reduce to 11900-11800 revolutions per minute.

Having reduced maximum speeds, it is possible to get an enriched mixture, so more gasoline with butter is supplied to the combustion chamber. This eliminates the overheating of the engine, and thereby, wear of the details. After the end of the processing process, the carburetor of the chainsaw will be needed to adjust again to the operating mode.

Interesting to know! If there is no tachometer, then the tuning of the carburetor of the chainsaw is carried out by moving the screw H by a quarter of turnover towards increasing the mixture (rotation counterclockwise). Similarly, low speeds are reduced, which is achieved by moving the screw L by 1/4 turnover.

The tuning of the carburetor can be performed on the chainsaws of professional and semi.Professional purposes, but the procedure is not mandatory if the documentation from the manufacturer does not say anything about this. The running.In will be successful if the carburetor is not adjusted, but at the same time exclude the likelihood of increasing revolutions to the maximum value. Household tools do not need at all to perform such actions. After setting, the engine is launched.

What gasoline to fill in a chainsaw

A mass of disputes goes around what gasoline is poured into a fuel tank. For foreign models, manufacturers recommend using 92nd gasoline. Local manufacturers of the tool, on the contrary, recommend the use of fuel of a lower brand, for example, AI-80. But everyone agrees that it is not recommended to use gasoline with an octane number of 95 and above. This is due to the presence of special additives (additives) in it, which change the quality of the fuel, but unlike automobile engines, the tool has a more sensitive filling. Extra components are deposited on the internal parts and when accumulating a critical mass, they exfoliate and violate the operation of the mechanism.

In some cases, a mixture of the 92nd and 80th unearthly fuel is used for refueling. The best recipe is to follow the instructions attached to the tool. It usually indicates the “correct” option for this model, and by default, gasoline of the 92nd brand is recommended.

Preparation of fuel mixture for a chainsaw

Gasoline should be with an octane number no less than AI92. You can also fill in AI95, but its quality at our gas station leaves much to be desired, so if you are not sure of the 95th, it is better to take gasoline AI92 gasoline to dilute gasoline into a chainsaw. You should not take gasoline in the same way for a long time in the canister, tank or any other capacity. Gasoline for the preparation of the fuel mixture in the chainsaw should be fresh, otherwise it loses its properties, in particular the octane number, and even if you run the chainsaw on such fuel, it will not give out full power. And the saddest thing in this case is that the failure of the chainsaw due to poor.Quality fuel is considered a non.Warranty occasion and leads to expensive repairs. Sometimes it’s easier to buy a new chainsaw than to repair it after such a breakdown!

Selecting two.Stroke oil for a chainsaw

Having decided on the question of how to breed gasoline with butter into a chainsaw, it is worth finding out which type of lubricant is better to use. First you need to understand that mixing fuel is required exclusively with two.Stroke oils, but not motorized for automobile engines, and even more so, working out.

Special oils are called. Two.Stroke. By color, they are not only red, but green and blue. Red color indicates that it is mineral (cheapest). Blue and green. Semi.Synthetics. Semi.Synthetics are naturally better, but when it comes to one.Time use (t.E., When the lubricant burns with gasoline, then mineral oil is the best option in terms of cost and reliability). The color of the oil also indicates the use of the appropriate additives, but the most important thing is to choose a lubricant, well.Known manufacturers need. By color, you can determine that fuel is mixed with grease.

Today it is very easy to buy a fake or lubrication of low quality, so you should not save. The following manufacturers are recommended to choose two.Stroke oils:

If when buying expensive oils, they tell you that you are overpaying for the brand, then this is so. Only you pay for the guarantee that the purchased substance is high.Quality, and has only a positive effect on the engine engine. No need to look for options cheaper, because saving on fuel and lubricants, you reduce the life of the engine and the entire tool in general.

Interesting to know! Two.Stroke oil has a different consistency and the number of additives. Motor oil is intended for constant lubrication of mechanisms, and two.Stroke lubricates the parts when contacting it, and when it enters with gasoline into the cylinder, burns out.

Summing up, it should be noted that the chainsaws are necessary to refuel a gas-oil mixture in a ratio of 1 liter of fuel add 20 ml of oil. If you use a proportion using 25 ml of lubricants, then nothing terrible with the ICE will happen.

Recommended sequence

In accordance with the standard fuel mixture preparation technology, the calculated amount of oil is poured into the tank filled up to half.

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

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

The expired mixture initiates the formation of tarry compounds contributing to the clogging of the jackets, the formation of soot and the limitation of the mobility of the piston rings. In order to save, the overexposed composition can be spent, adding to a fresh mixture up to 15-20 % of the total volume.

What gasoline to fill in a chainsaw

Chainsaw is considered the most popular type of manual tool used to work with wood. Unlike electric saws, it is adapted for autonomous use, which is a convenient, and sometimes only possible effective way to cut logs and other wood materials in remote territories. For this, you only need to have fuel for a chainsaw in the required quantity and know the rules for refueling the tool.

Most modern chainsaws are driven by a single-cylinder two-stroke internal combustion engine operating on the 92nd or 95th gasoline. Old domestic models should be refueled with a fuel with an octane number 80.

The speed of the chain transmission drive is determined by the speed characteristics of the motor, which usually exceed 10,000 revolutions per minute. Therefore, the fuel mixture for the chainsaw equipped with a speed engine must necessarily contain special Motor oils.

The fuel system of the chainsaw includes:

  • Gas tank;
  • Fuel filter;
  • Carburetor;
  • Hoses along which fuel is supplied to the mixture with air and further into the motor cylinder.

Fuel filter fixed at the end of the hose lowered into the tank. With the engine operating, uninterrupted pumping of fuel provides a small pump built into the carburetor. To start the engine, mechanical pumping of gasoline is required with an additional device. Primer. The tank protection from creating a vacuum when a fluid level is reduced during operation is provided by a special air valve. Carburetor is responsible for the proper ratio of fuel with pumped air during the creation of the fuel.Air mixture, which is filed for combustion in the cylinder. The entire fuel system works in agreement with the ignition system to the beat of the piston.

Why are AI-92 pour into chainsaws?

Low.Powerful chainsaw engines, not all types of fuel are suitable for them. That is, their ICE works with gasoline, in which only certain impurities. If there are other impurities or another ratio, this can lead to an explosion. For example, AI-95-high-octane, high-quality, elite gasoline. AI-95 is better in terms of security-it has impurities that prevent it from detonating. But due to the same impurities, the performance of the chainsaw engine may decrease and the wear of the elements accelerate. You can draw a parallel between filling such gasoline in the saw and the use of rocket oil in the machine.

Use lower-octane fuel is prohibited due to the likelihood of an explosion.

How much oil is required to add to gasoline?

Types of oils used for breeding in gasoline

There are no oil pumps in the chainsaws, so the combustible mixture alone cannot be used. Carefully read the instruction that is attached to the manufacturer to each product. A lot of information on the Internet, finding it is not difficult.

If the lubricant is absent, then the saw after a short time will fail. It is recommended to make preventive maintenance of the unit, pour properly diluted fuel, in which case the tool will operate for many years.

If we take, for example, the Huscovarna chainsaw, then unhealthy gasoline with the first additive of the brand 92 is suitable. If the composition has a greenish kner, then this suggests that the product is a premium class. AI-92 is an optimal product that can be suitable for such a device. On average, professionals advise adding one liter from twenty to 50 ml of machine oil. 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 machine oil and gasoline, in what proportions? This question arises for all users. First you should stock up on containers:

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

Types of oils used for breeding in gasoline

What proportions should be done? Engines are mainly two.Stroke, so the mixture is usually 1:50. Russian.Made chainsaws function with the products of such 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, oil proportions in them vary from 40 to 49 shares.

Shades of oil can vary significantly, this should be taken into account during operation. For example, the company “NR” produces machine oil of reddish ring. If the composition has a greenish (sometimes blue) shade, then this is a sure sign that the product is a synthetic premium class. The quality of such compounds is high, the cost is also rather big.

Gas station refueling

The process of loading the fuel mixture into the tool gas tank itself is quite primitive. It is necessary to unscrew the neck and pour gasoline through the filter element. The main questions are about the preparation of a mixture from gasoline and oil. Here it is necessary to withstand the correct proportions on the recommendations provided by the manufacturer. It is necessary to refuel a chainsaw only with a mixture with the correct ratio of components, as this affects the life of the engine.

Gasoline and oil ratio

The regulatory documentation adopted in the Russian Federation determines the standard ratio of gasoline-oil mixture used for two-stroke engines-this is 1/50. When calculating according to the rules of the proportion, it turns out that in 0.5 liters of gasoline it is necessary to dissolve 10 milliliters of engine oil. This is the basic value that each manufacturer changes based on the features of the design of his engine. It is recommended to use only an indication on the composition reflected in the tool passport.

Echo CS-400 18 Gas Chainsaw

There are other proportions for benzo tools that are actively used by foreign manufacturers, for example:

Independently determine the proportion of fuel depending on the type of engine. It is impossible.

How to mix the fuel mixture correctly

Initially, it is necessary to prepare containers and a measured tool with the required accuracy. All dishes should be cleaned and not contain the remains of other components, dirt or water.

A graduated canister, as well as a regular medical syringe for 10-20 mg, is suitable. Pour gasoline to the label into the canister, and then use the syringe, add the calculated amount of motor oil. After that, the canister is closed with a screwed plug and mixed with viasal movements for 3-5 minutes.

Work must be carried out in a well.Ventilated room. It is forbidden to use a plastic canister due to a possible formation of a spark (with subsequent fire) due to static electricity.

Storage conditions for the finished mixture

It is impossible to store a gasoline-oil mixture for a long time due to the possibility of decomposition of components and deterioration of quality. The optimal shelf life is no more than 90 days.

It is necessary to use opaque canists for storage, it is advisable to maintain a temperature of 15-20 degrees in the room and do not have a mixture near heating devices (or other heating surfaces). It is required to provide conditions in which direct sunlight does not fall on the mixture.

Which octane number to use. 92, 95 or 98?

Here the most interesting begins. Is it possible to refuel a chainsaw 95 with gasoline? In all the instructions for the operation of the chainsaws, manufacturers indicate with fat font: “Do not use gasoline with an octane number above 92 for the preparation of the fuel mixture”. It is understandable, but apparently not everyone, t.To. Once from timely, a chainsaws with a burnt cylinder bring to service centers!

Let’s figure out which gasoline is to pour in the chainsaw and which! For all two.Stroke engines, you need to use 92 gasoline, it is the tool that is designed for it.

Pouring 95 gasoline, detonation (impetus of the piston into the anti-income) will begin to occur in the engine, something like a micro-impact that will occur almost at each turnover of the crankshaft. I think everything is clear about 98 gasoline, the effect will be even stronger, and it will already be mini strikes.

Fuel consumption

One of the most important issues that arises from the owners of the saw.Tool, because everyone wants to know what to count on.

The volume of almost all tanks is approximately 500 ml. If the power of the chainsaw is 2 kW, then the fuel mixture consumption will be approximately 1.2 liters per hour of operation. If you simply say, such a tool will be able to work for half an hour without a break at maximum speeds. If the chainsaw is not so powerful, then the volume of the tank will have less. So the user can independently control the fuel consumption.

Over time, the user will learn without any help to serve his tool. The main task is to preserve the economic unit in good, working, using high.Quality fuel mixtures. Observe the safety rules when preparing combustible fluid. This will help save the tool, and also not harm yourself and the environment.

Useful tips:

The correct operation of your technique is fully dependent on you. First, do not disdain manufacturers with indicators or, in extreme cases, with indications on the oil packaging. This will help to avoid unpleasant situations. The neighbor does not always know how best to do. Cheapness of oil and gasoline is not an indicator of high quality, because a tool breakdown can do much more expensive (about 80 % of the cost of a chainsaw) than the agricultural mixture saved on the fuel mixture.


Gene, Ulyanovsk:

“I want to share an important observation. It will be useful for owners of chainsaws from the USSR. Ural or friendship. It was previously believed that for one liter of gasoline for such saws you need 50 grams of oil, and even 60 grams when running around. Now the oils are better, so you can safely pour 20 grams per liter! This observation greatly facilitated the operation of the chainsaw, and relieved the oversupply of the oil. I recommend to everyone who has such “old men”, try such a proportion for their tools ”.
