what is the proportion of oil and gasoline for a Husqvarna 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 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?

Independent analysis of cost and customer reviews

The average price of a branded product across three popular stores in our city exceeded the average market price of a similar product by 8, 6 and 12%, respectively, for each of the listed types of consumables. Reviews of these operating fluids were studied in three thematic forums; Only the opinions of participants with experience and direct or indirect evidence of the use of the products of interest to us were taken into account. The main results of the analysis are as follows: the use of the considered liquids has never led to damage to a branded instrument used for its intended purpose; These consumables are also approved among owners of Partner, Stihl and other brands of chainsaws.

Maintenance of the Husqvarna 135 chain saw

1. Timely refueling of the saw with the fuel mixture.
2. Monitoring the lubricant level.
3. Monitoring the condition of the guide.
4. Sharpening the chain.
5. Chain inspection and maintenance.
6. Maintenance of filter elements.
7. Repair work.
8. Care and cleaning of the chainsaw after each use.
9. Carburetor adjustment.
10. Oil supply system maintenance, etc.

Carburetor adjustment

Carburetor adjustment consists of several stages:

• Start the saw and turn the high and low speed adjustment screws until they stop. Unscrew it back 1.5 turns;
• Warm up the saw for about 10 minutes. Set the idle speed using the idle speed screw. With the correct settings, the chain will not move along the bar at idle;
• Check the saw for acceleration. When you press the accelerator, the speed should increase quickly.

Important Terms

The power plants in chainsaws are internal combustion engines, fueled by certain brands of gasoline diluted with the required parts of oil.

Knowledge and strict adherence to the composition of a combustible mixture is the key to long-term operation and productive use of small-scale mechanization units.

The main fuel component is AI grade. It is not recommended to use below or above 92 octane. Optimal for many types of mechanized sawmills, domestic or foreign made.

The ideal ratio of gasoline and oil for a chainsaw:

The instructions attached to the purchased goods indicate the consumption rates of fuel and lubricating fluid. Violation of the requirements leads to loss of power and premature wear of the internal combustion engine. The truth was obtained through research methods, empirically in our country and abroad.

Need quality components

Practice proves the influence of the quality of the prepared mixture, taking into account the required proportions, on the service life of the tool, power, productivity:

1. It is not recommended to use components that have expired.
2. It is especially important for the components of gasoline and oil - do not use components obtained from gas condensates, since the molecular structure contains harmful water for internal combustion engines.
3. Partial non-compliance of AI-92 with international standards. AI-95 grade is saturated with additives that dampen the detonation moments of internal combustion engines.

The noted disadvantages limit the operational life of hand-held chainsaws, the internal combustion engines of which operate on complex mixtures of combustible mixtures.

Mixture proportion for “Calm”

The German family company Stihl has production facilities in many countries around the world. The office is located in Waiblingen. Among the range of products produced for the needs of forestry, small-scale mechanization equipment takes pride of place.

Today a liquid golden age has arrived for the Stihl chainsaw:

The manufacturer has set the oil dilution standard at a ratio of 1:50. The proposed proportion establishes the possibility of diluting 1 part of oil in 50 parts of gasoline. Or in a ratio of 1:40.

The calculation is simple. We know that 1 liter of flammable liquid equals 1000 milliliters. Divide the value by 50, we get 20 milliliters of oil. Using a similar algorithm, its volume is determined, recommended in a ratio of 1:40. Having made simple calculations, we get the value of 25 milliliters.

Areas of application and equipment for Husqvarna 262 XP and 268-18 chainsaws

These tools are in demand due to the rapid increase in speed and the ability to effortlessly turn the saw element at maximum engine speed. The models are designed with durable heated handles, making them suitable for use in winter.

Saw features include:

• The power of the models is 4.7 liters. With. or 3400 Watt;
• The volume of the fuel tank is 590 ml;
• Oil tank capacity – 500 ml;
• Weight when ready for use is 7.2 and 7.5 kg. respectively.

These chainsaws are used for cutting thick beams and logs, as well as for felling medium and large trees. In addition, high power and simple design allow you to make an ice auger from a chainsaw or other necessary equipment.

Proportions for Swedish Husqvarna chainsaws

What exact rate of lubricant is required to prepare the combustible mixture necessary for the normal operation of a two-stroke gasoline internal combustion engine? Buyers will learn about this from the instructions supplied with the product. But documentation is often lost among papers. In this regard, it would be useful to remember that manufacturers use transmission lubricant for mixing with gasoline. The Swedish company is known on all continents of the planet for supplying reliable goods to trade markets. Oil for Husqvarna chainsaws is strictly recommended by the manufacturer.

Depending on how much power is required to be obtained from the units, select the appropriate component dilution:

One liter of fuel is diluted with 40 to 50 parts of oil. These are the ideal proportions of gasoline and oil.

Along the way, we inform you that only unleaded gasoline of the AI-92 or AI-95 brands is used. A leaded combustible product is considered a poor choice for internal combustion engines, as it shortens the engine's service life.

Structure company of Husqvarna HP

The brand structure of the Swedish manufacturer Husqvarna HP includes a company that produces mechanized hand tools and lubricants for them, and effective chemical additives.

Chainsaw manufacturer Partner has developed an original ratio of fuel and oil for two-stroke power plants:

The mixing ratio of the fuel consistency is derived by the standard formula 1:50. This is a constant. That is, 20 milliliters per 1 liter of AI-92.

There are moments of non-compliance with the standard approach to dilution with a lubricant product of the company’s own production. This is when the internal combustion engine goes through the break-in stage. The fuel mixture allowed for the engine is 1:40.

Impression of the availability of official information on the topic

Very often, manufacturers do not indicate all the consumer or technical characteristics of the product, so to obtain the necessary data you have to use the search on your own for a long time or communicate with the engineers of the development company. For this review, all the necessary information was found on the company's official website. When the manufacturer does not hide anything, this is, as a rule, a sign of a quality product, and in our case it is present. The only thing worth noting is that navigation on the site is not very convenient. It is easier to find the required document from the outside through a search engine than from internal links.

Proportion for chainsaw Friendship

The pedigree for the Druzhba chainsaw began in 1953 with development at the Progress ZMKB. The production of goods was entrusted to two enterprises - the Siberian Instrument-Making Plant and the Perm Machine-Building Plant. Mass production of the mechanized product began, which is still the trend of the day, since the unit was systematically modernized.

Engines use low octane fuel. The unit shows the highest performance when filling the internal combustion engine with AI-76 and AI-80 gasoline.

It is recommended to dilute gasoline and oil according to the following algorithm:

Take 2 clean containers, dried from moisture with volume marks. Then the fuel is diluted with two-stroke oil in a ratio of 1:50. That is, the fuel is diluted with 20 milligrams of oil.

Briggs&Stratton 5W30 SL/CF oil 1l

Briggs&Stratton oil (100007W) for four-stroke engines SAE 5W30. This is a synthetic winter oil specially designed for 4-stroke air-cooled engines. Due to its characteristics, synthetic oil is capable of operating at a high level for as long as possible. Compared to mineral oils, synthetic oils can be used over the widest temperature range, have better low temperature fluidity, better heat stability, better oxidation stability, low volatility, low carbon formation, and better wear control. Accordingly, such oil reduces the risk of equipment malfunctions, ensures uninterrupted operation, reduces maintenance costs, and extends engine life.

Why do you need to maintain the proportion of gasoline and oil?

Many buyers, when purchasing a chainsaw, are perplexed as to why the exact amount of oil and gasoline should be added to the oil recommended by the manufacturer. It's all about the subtleties of a two-stroke engine, which differs from its 4-stroke counterpart in a number of specific design solutions.

One of them: the production of a single-cylinder engine in which there is no crankcase for filling lubricating mixtures. This is seen as a technological success of its time.

You can imagine how the incoming combustible mixture loses oil molecules that settle on the cylinder stacks. Subsequently, it creates a sliding protective film in the rubbing components and parts of the internal combustion engine, reducing the physical contact of the piston rings with the cylinder wall, connecting rod and crankshaft.

To ensure maximum performance of the unit, long-term operation is achieved by the correct ratio of pure gasoline to the recommended oil. Violation of the rule guarantees a quick exit of the instrument from its functional state. A breakdown of the internal combustion engine will require significant funds for repair or replacement with a new analogue.

Many users of hand-held power tools consider the oil container present in the unit to be a reservoir for lubricant and power unit. This is fundamentally wrong. The lubricant is intended for the chain during operation. But only. The oil tank is a priori not connected by pipeline to the engine.

Technological features

Husqvarna always pleases with technological innovations. This time the 120th model has:

• An updated Air Injection air purification system that sorts particles: it drives smaller ones into the filter, throwing large ones onto the walls, which do not clog it. This increases the service life and service life of the saw several times;
• For easy starting and stable operation, the chainsaw has a combined engine stop control;
• LowVib - a patented anti-vibration system from Husqvarna, which is considered one of the best in the world;
• The engine uses X-Torq technology, which is designed to protect the environment from harmful fumes and exhausts, and also increases torque by 10%.

X-Torq - the photo shows how this technology works, or rather, how the principle of afterburning already exhaust air works

Rules for preparing the mixture

Even experienced lumberjacks do not always correctly prepare the fuel mixture for a chainsaw if the work is done in a hurry.
The algorithm of actions is as follows:

When making a mixture of gasoline and oil, you should adhere to the prohibitive rules - you should not try to mix it in the gasoline tank of the tool.

It is recommended to store the finished flammable product for 14 days. If more, the oil will settle to the bottom of the container. A new shake of consistency will be required. Busy people often forget about this.

Description

The Husqvarna 135 chainsaw is a basic model that is lightweight and very convenient for use at home for cutting wood, collecting firewood, performing garden work such as trimming branches and branches, working with wood in construction, and more.

The Husqvarna 135 chainsaw is the latest generation of saws that minimizes harmful emissions. The tool is equipped with a two-stroke gasoline engine with a power of 1500 W. The engine cylinder capacity is 40.9 cc. The engine is designed using X-Tord technology, which ensures economical consumption of the gasoline-oil mixture and reduces the amount of harmful emissions.

The difference between the Husqvarna 135 chainsaw and the Husqvarna 140 model is as follows:

• the 135th saw has a quick-release mount for the air filter;
• power of the 140th model - 1600 W, 135th - 1500 W;
• Another difference is the price; the 140th Husqvarna chainsaw costs more than the 135th.

Both chainsaws fall into the “standard” or “regular saws” category, as stated by the manufacturer itself. They are perfect for household use and ordinary woodworking tasks; they have similar technical characteristics, namely the same engine size and tire length. The fuel consumption of the 140th model is 930 ml of fuel per hour, while the 135th consumes 1.1 l/hour.

How to increase the service life of a chainsaw?

The chainsaw will be technically serviceable under one condition:

When purchasing a tool, read the manufacturer’s instructions and operating recommendations in detail.

Strictly adhere to and comply with the requirements for the selection of components for the formation of a combustible mixture consisting of gasoline and the recommended oil.

Oils intended for motor vehicles cannot be used to form the working product. This is strictly prohibited.

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.

Stihl canister with compartments for oil and gasoline

This canister has two compartments for storing oil and gasoline separately. The gasoline container has a volume of 5 liters, and the oil container has a volume of 3 liters. Often, many owners of gas-powered tools with two-stroke engines carry oil in this canister in one compartment and a ready-made fuel mixture in the other.

Husqvarn canisters have a special feature: the oil container can be detached from the main one and used separately.

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.
