What gasoline is needed for a chainsaw

What gasoline is needed for a chainsaw?

Gasoline saws require a specific type of fuel, which is a specific mixture of gasoline and engine oil. Most gasoline saws run on a 50: 1 mixture of gasoline and oil. It is important to check the owner’s manual for the exact ratio of components, taking into account the needs of a particular chainsaw.

Chainsaws need lubricating oil to get the right oil / fuel mixture. This will keep the chain running smoothly. It is important to look for a chain saw with an integrated oil chamber that automatically supplies oil as this will save the operator time and effort. Most models come with these standard systems, but they are worth checking out before purchasing. Without using your chainsaw regularly, you need to drain fuel and oil after each use.

gasoline, needed, chainsaw

Modern saws have special fuel needs. For all newbies in terms of using a chainsaw, it is important to consider that it is necessary to use a certain fuel with caution in order to obtain high performance of a chainsaw. It is important to know what kind of gasoline to pour into the chainsaw.

Many chainsaw brands recommend using high-octane unleaded gasoline. Many saws are designed to burn 89 octane or higher fuels. Most standard grade fuels have an octane rating of around 87. That’s not enough. Professionals do not recommend using high octane fuels. Knowing what gasoline is needed for a chainsaw prevents a lot of problems.

Low-octane fuel, of course, will not cost so much, but it reduces the power of the chainsaw and negatively affects its performance. Chainsaw electric motors are highly efficient. They generate more energy than many racing car engines and require high-octane gasoline.

But even high-quality gasoline for a chainsaw will not be the key to successful work, read our article. Dilute gasoline with oil correctly.

Many professionals are unaware that low-octane gasoline not only degrades the performance of the saw, but can also damage the engine. Many are convinced that the air-fuel mixture should burn quickly. It is not true. The mixture should start burning and move through the combustion chamber until it reaches the cylinder walls. If burned early and maximum pressure builds up before the piston starts to move down the cylinder, engine performance will decrease.

The octane index is directly related to its ability to be resistant to detonation. Knocking is the sound of an air / fuel mixture “exploding” inside the engine. This phenomenon is familiar to many people who use poor quality gasoline in their car or truck. In this case, there is also a crackling sound from under the hood. This sound indicates a decrease in engine energy and strong pressure on internal components. This can cause heat build-up. Sometimes the sound of a running saw drowns out this noise. And therefore, using low-octane fuel, the operator may not be aware of the existing problem until it is too late.

Engine damaged by low octane fuel is a common problem. It was caused by the use of fuel that did not have enough octane. The only thing that a person needs to understand is that modern chainsaws need fuel with a minimum octane rating of 89. Many professionals suggest using the option with an octane rating of 91, which is available at most gas stations.

Thus, unless the saw is modified to have more compression force and ignition acceleration than factory specs set, fuels greater than 91 octane will not provide any real benefit. In fact, some of the additives in such fuels are undesirable. Knowing what gasoline to fill your chainsaw with, you don’t have to worry about the performance of the tool, its power and smooth operation.

One of the most common problems with a chainsaw is the one in which gasoline does not flow into the chainsaw. Follow the link to our article with methods of fixing the problem.

Choosing gasoline for a chainsaw

When there are a lot of logs to cut or when you need to do some difficult pruning jobs in your garden, a chainsaw is a good choice. It handles woodwork faster than any other technique and can be used anywhere without a rear power cable.

How a chainsaw works?

The gasoline engine drives a metal chain with a large number of cutting “teeth”. They revolve around the guide bar at high speed. As the chain makes contact with a log or tree trunk, its teeth run along the surface, cutting through the wood. The circular motion of the chain keeps the teeth in contact with the tree, so the saw continues to cut until the job is complete or until the chain stops.

Most gasoline saws have two-stroke engines that are similar to those used in mopeds or boats. They are similar to each other in how they work. It should be borne in mind that the engine of a gasoline chainsaw will require regular maintenance in order to keep it in working order.

The advantages of a gasoline saw

The advantages of a chainsaw will be felt by every person who at least once uses this tool to perform certain tasks in the garden. Of course, like any other tool of this type, your chainsaw will require regular maintenance, including:

  • engine maintenance;
  • fuel tank maintenance;
  • sharpening of cutting teeth;
  • keeping the chain in the correct tension.

Gasoline saws are also heavy, so it’s worth trying them at least once before making an expensive purchase. This is necessary in order to check how the tool suits a person, how comfortable it is. But do not forget that there are many lightweight options on the market now that are easier to manipulate during work.

One has only to think about how much work can be done with a quality gasoline saw. Many people worry that gasoline saws will be noisy. Some of them are, indeed, more noisy than others, but there are also models that are quieter and, importantly, have a vibration damping system.

Pros:

  • Powerful, portable, great for a variety of woodworking applications.

Minuses:

  • High service, overwhelming emissions, cost.

Chainsaws come in a variety of sizes and capacities depending on the type of work they do, from trimming shrub branches to cutting large trunks. Generally, there are three categories:

  • household use;
  • heavy use;
  • professional use.

Useful Tips

Experts and manufacturers do not recommend storing a large volume of fuel and storing it for a long time. Oil and gasoline can behave differently in a mixture, it all depends on the brand, quality, degree of additives and additives. Oxidation and crystallization processes take place. The result can be disastrous and incur additional financial costs for the user: incorrect operation or engine failure.

Fuel is prepared for a maximum of three fillings, mixing in containers made of metal or durable plastic. Conventional plastic breaks down by reacting with gasoline, spoiling the composition of the fuel and creating a danger of sudden ignition.

Gasoline for chainsaw: what to pour?

Since a two-stroke engine is used on chainsaws, where it is structurally impossible to install an oil pump, you cannot pour pure gasoline into a chainsaw! The chainsaws are filled with a fuel mixture of gasoline and oil. The proportions for different saws are set by the manufacturer, the specific number is indicated in the operating instructions.

The question is often asked: gasoline for a chainsaw. what to pour? I will try to answer in more detail # 8230.

For domestic chainsaws (Ural, Druzhba, 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 foreign 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 foreign manufacturers, the proportions are usually equal to 1/40 (100 grams per 4 liters of AI-92), 1/50 (100 grams per 5 liters of AI-92). Use AI-92 gasoline. 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.

To measure the required amount of oil, you can use a syringe, a measuring bottle, a special dispenser or, for example, a bottle with a dispenser from Stihl.

Oils from different manufacturers in different colors. As you can see in the picture above, HP calm oil (mineral water) is red, more expensive synthetic ones are green. Husqvarna oil can be green or blue.

REMEMBER! IN THE CASE OF A CHAINSAW OUT OF THE SYSTEM FOR THE CAUSE OF FILLING THE WRONG MIXTURE, THE REPAIR WILL BE NON-WARRANTY!

It is better to overfill than underfill! If it is written 1/50, then when you pour 25 grams per liter, terrible will not happen, since coking 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 ready-made fuel mixture for more than a month (less is better), as it loses its octane number (gasoline fizzles out # 187).

Run out the entire tank or drain before the season to avoid loss of gasoline quality and wear of rubber and plastic seals.

Never use oils for mopeds. they are designed for lower rpm

What gasoline to pour into a chainsaw

In general, a standard chainsaw runs on 92 gasoline. Its compression ratio in the engine is designed for just that. Also, in view of the two-stroke engine, gasoline is mixed with oil for just such an engine. It is possible by eye. If you do not have knowledge, you can observe the ratio of 1:50 oil to gasoline.

Since the basic requirements of the chainsaw relate to the brand of gasoline on the principle of “no less than” in terms of octane number, in practice it is also not recommended to fill in more than 92nd. At 95th and already 98th, the piston will overheat the parts. If you fill up with gasoline lower in octane number, the saw will not work, it will stall and deteriorate. You can try to fill in diesel fuel. Some chainsaws are stable. But sometimes this can cause deterioration. You can check this only at your own peril and risk with practice.

Gasoline and oil proportions

In view of the two-stroke type of engine, fuel is purchased separately in a pure form, and then mixed with oil intended specifically for this engine version. Most experienced users mix the substances in proportions 1:50. In the photo you can see the popular high quality products used for the preparation of the fuel mixture.

Important points to observe:

  • domestic chainsaws (Ural, Stihl, Druzhba) work with an oil component of the M8-B, M-12TPU, M8-B, TP, MGD-14M brands, sometimes foreign options can be used; the recommended proportion is 100 g of oil per 2.5 liters of gasoline AI-80 brand
  • foreign models (Husqvarna, Partner) run on foreign-made oils (1:50 or 1: 40), differ in minimum consumption.

How to properly prepare the fuel mixture

When purchasing gasoline for a chainsaw and oil, you should think about additional accessories. To measure and the ability to pour the mixture into the chainsaw, use the following tools:

  • breeding container (plastic or metal),
  • syringe,
  • measuring bottle (suitable for measuring gasoline),
  • dispenser,
  • watering can (pour into the chainsaw).

A very convenient thing is a special bottle with a dispenser from the Stihl brand (pictured), which allows you to perform all actions accurately and quickly, accurately measuring the right amount of each substance. Choosing gasoline for the Stihl chainsaw (Friendship, Husqvarna, Partner), you should pay special attention to the second component.

Oils from different manufacturers have variations in shades. HP products are red, the premium synthetic segment is mainly represented by green. If you take gasoline for a Husqvarna chainsaw, then the oil must also be of the appropriate brand, not cheap (green or blue in color). The video shows the process of mixing fuel.

What gasoline to pour into a chainsaw

What gasoline to pour into a popular brand chainsaw

A chainsaw is a convenient unit that can solve a lot of everyday problems. Powered by fuel that you need to prepare yourself just before filling it into the tank. Those who purchased a functional device for the first time are interested in the question of which gasoline to pour into the chainsaw. It is possible to avoid breakdowns and extend the life of the device only if the manufacturer’s recommendations specified in the instructions are followed.

What gasoline to fill?

Modern brands of chainsaws (Husqvarna, Partner) from foreign manufacturers will run smoothly on AI-92 gasoline. it will ideally match the engine. The user manual may also show grade 95, but this must be filled with care. The quality of this gasoline is currently being questioned, its octane number is increased with the help of various additives. This is detrimental to the chainsaw engine, which can lead to a major overhaul of the unit. And its cost will be at least half the cost of a new model, excluding spare parts to be replaced.

For devices from domestic manufacturers (Ural, Stihl, Druzhba), AI-80 gasoline is recommended. It is important for the user that his consumption is minimal.

Gasoline consumption and operating time

An important question is the gasoline consumption of the chainsaw, because the user must understand what to count on.

The volume of the fuel tanks is approximately 0.5 liters. When the power of the device is 2 kW, the consumption of petrol and oil will be about 1.2 l / h. Translating into a language understandable to the user. for about 30 minutes, the chainsaw can work in uninterrupted mode at maximum speed. Less powerful devices have a smaller tank volume, gasoline consumption is controlled by the owner independently.

Over time, you will learn how to independently service this household unit. The main thing is to keep it working and use only high-quality fuel. It is necessary to mix in compliance with safety rules so as not to damage your health or the environment.

Chainsaw device

Each chainsaw has different technical data and can do different work.

Powerful saws are suitable for felling centuries-old trees, small-format chainsaws are more suitable for various tasks in the home garden:

  • Cutting tree branches
  • Harvesting firewood

Chainsaw standard blocks:

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

Each chainsaw requires high-quality fuels and lubricants, it is they that ensure long-term productive operation of the unit. What gasoline for the chainsaw to fill, in what proportions?

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

The chainsaw is simple to operate and is sometimes needed in a private household. The device cannot fully function if you do not use the correct fuel mixture, which you should be able to prepare.

How much oil is required to add to gasoline?

Types of oils used for dilution in gasoline

Chainsaws do not have oil pumps, so combustible mixture alone cannot be used. You should carefully read the instructions that are attached by the manufacturer to each product. There is a lot of information on the Internet, it is not difficult to find it.

If there is no lubrication, the saw will fail after a short time. It is recommended to do preventive maintenance of the unit, fill in 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 addition of grade 92 is suitable. If the composition has a greenish color, then this indicates that the product is a premium class. AI-92 is the optimal product that can be suitable for such a device. On average, professionals advise adding 20 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
  • Dispenser and syringe
  • A watering can, which will allow you to pour the substance into the tank

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

Types of oils used for dilution in gasoline

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

  • M8-B
  • M-12TPU
  • TP
  • MGD-14M

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

Shades of oil can vary significantly, this should be taken into account during operation. For example, HP produces reddish engine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is synthetic premium. The quality of such compositions is high, the cost is also rather big.

Fuel selection

Which fuel to choose for a chainsaw is a non-idle question, the success of the unit directly depends on it. According to existing canons, good gasoline for a chainsaw is considered not leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in a canister for a year or a year and a half, this will adversely affect the nature of the device’s operation, therefore, the substance should be prepared before starting work.

It is important to monitor that there is no alcohol in the fuel, any additives that can disrupt the functioning of the power plant. Experts are still debating which is better than 95 or 92. The first has more stable detonation indicators, but most often the 92nd is still used. The reason is simple: questions often arise by the 95th, it contains a large number of various additives that have a bad effect on the operation of the saw engine. Micro-knock occurs (piston impulse in the opposite direction), which occurs practically at every revolution of the crankshaft. If the octane number is even higher (98), then the micro impacts will become even more intense.

The consequences of improper gasoline on the quality of the unit can only be negative:

  • The mechanism will be difficult to start.
  • The power will be minimal.

Correct Way To Mix Gas and Oil For a ChainSaw, WeedEater etc. Video

  • Parts will wear more intensively.

The highest quality product is considered to be the product of Husqvarna, followed by Lukoil machine oil.

The advantages of these oils:

  • Low consumption.
  • Maintaining quality.
  • Ability to maintain technological qualities for a long time.
  • Can work in extreme conditions.
  • No toxins.
  • Minimum amount of carbon deposits.

Many professional tools use a lubricant made using API-TB technology (USA). Products made according to the JASO-FB method (Japan) are also popular.

It is permissible to mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are incompatible. The best oil for household chainsaws is considered “Standard”, for professional equipment the technical fluid “Ultra” is optimal.

Some oils can successfully replace each other. For example, substances produced by Husqvarna and Stihl. Lubrication for scooter engines or motor boats is not suitable for chainsaws, the oil quality in them is low. If the proportions of oil and gasoline are not maintained, then the tool will quickly fail due to the abundant formation of carbon deposits.

Advantages and disadvantages of oil

Any quality machine oil has its pros and cons.

Any quality lube has its pros and cons. Some experts say that any chainsaw oil will work. This is not entirely true, almost any substance can be used for the Hurstavna chainsaw, but the Stihl chainsaw only requires gear oil. 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, which has a well-known brand name.

Seasonality affects the density of the product:

  • Air temperature.
  • Humidity.
  • Solar radiation intensity.
  • Pressure.

What are the features of different oils, you can find out precisely by carefully studying the label on the container. In the absence of instructions or labels on the packaging, you should refuse to use such a substance. At the same time, the performance characteristics of the oils should not change dramatically with a difference in temperature conditions.

You should not use any substitutes, often there are counterfeit products among them (up to 20%). It is quite difficult to distinguish a fake, you need to have 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 done in the ratio:

The performance characteristics of mineral or organic oils intended for the chain itself are not suitable for preparing the fuel mixture. The finished product is poured into the tank (up to half), then mixed (the container must be hermetically closed). Thus, a homogeneous composition is obtained. It is better not to prepare fuel ahead of time, it loses its functional properties rather quickly. At room temperature, flammable liquid deteriorates within two weeks.

Advice

Tips and life hacks are extremely useful in practical work, consider some of them:

  • It is convenient to use canisters with dispensers, while experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
  • Gasoline can actively evaporate, especially at high temperatures, a suspension falls out at the bottom of the canister, which cannot be poured into the engine.
  • It is recommended to prepare fuel for no more than three operational fillings.
  • The quality of the fuel can be affected by the material of the container, especially PVC materials react actively.
  • If the combustible mixture is poured of poor quality, the chainsaw may be removed from the warranty.
  • During operation, it is necessary to test the tightness of containers and the rhythmic operation of the engine.
  • One of the first signs of a malfunction is undue heating of the circuit.
  • Before subjecting the tool to severe stress, it should be tested at idle speed.
  • The tank is enough when working for half an hour.
  • There is still grease (residues) in the second container when it has run out in the tank.
  • If a large amount of smoke is generated during operation, this means that the fuel is of poor quality.
  • During the operation of the unit, do not approach an open fire.
  • (distance up to 2 meters).
  • Fuel should not be poured “under the rim”, leave a little space.

What gasoline to pour into a chainsaw

Everywhere and everywhere they write and discuss issues related to the choice of oil for a chainsaw, someone recommends only the original, and someone “everything is fine” and on a regular Lukoil 2T! They also raise a lot of questions about mixing gasoline with oil. the process of preparing a fuel mixture for a chainsaw has any more or less human resource. But, no one ever raises the importance of the issue of using gasoline in a chainsaw! Why? After all, all technicians and engineers know how the use of high-octane gasoline affects engines designed to operate on low-octane ones! The chainsaw is no exception!

  • How much gasoline is stored
  • Octane number
  • Dirty gasoline
  • Summing up

Octane number

This is where the fun begins. Can I refuel a chainsaw 95 with gasoline? In all operating instructions for chainsaws, manufacturers indicate in bold type: “Do not use gasoline with an octane rating higher than 92 for preparing the fuel mixture.” It is understandable, but apparently not for everyone. Once from time to time, they bring chainsaws with a burnt-out cylinder to service centers!

Let’s figure out which gasoline is worth pouring into a chainsaw and which is not! For all two-stroke saw engines, you need to use 92 gasoline, the tool is designed for it. Filling 95 gasoline, the engine will begin to detonate (pushing the piston in the opposite direction), something like a micro impact, which will occur almost every revolution of the crankshaft. About 98 gasoline, I think everything is clear, the effect will be even stronger, and it will already be mini strikes.

Dirty gasoline

Some owners of chainsaws are sure that if the tool works in conditions of constant dust (there is even an air compensator in the carburetor in case of a clogged air filter), it means that it is capable of swallowing gasoline with pieces of rust, and working with small pieces of metal will go to lubricate the chain, so?

This is another common misconception, never use gasoline from the bottom of a canister (especially a rusty one). The chainsaw has a carburetor, in which there are small channels that can clog up from these small particles, which in turn will lead to damage to the chainsaw and contacting a specialized workshop.

How much gasoline is stored

During long-term storage, gasoline evaporates (regardless of the brand), a sediment falls at the bottom, it loses its properties, in other words, it deteriorates. It is worth knowing that it is not the gasoline itself that ignites, but its vapors. Therefore, if there is a canister of gasoline in the garage since last year, then think, is it worth it? Better leave him to light the BBQ fire.

The use of “stale” gasoline for a chainsaw entails many problems:

  • difficult start;
  • decrease in maximum power;
  • increased wear of the engine parts of the chainsaw.

It is worth remembering that the prepared fuel mixture (gasoline with oil) is stored for no more than a month, after this time it should be disposed of. Using old mixture increases wear on the engine parts of the chainsaw. do not forget about it!

Summing up

In order for the chainsaw to serve for many years, never fill it with old gasoline, and you do not need to use grade 95 and especially 98 gasoline to prepare the fuel mixture, only 92. Also, do not forget about the purity of gasoline. no odens!

Gasoline with chainsaw oil. how to dilute and why it is done

Chainsaws from different companies are based on a two-stroke internal combustion engine, which drives the cutting headset of the tool. To drive the internal combustion engine, the proportions of gasoline with chainsaw oil are used. Combining gasoline with oil is a mandatory procedure, so if you just bought a tool, then you need to understand the features of its refueling.

Under the brand

For modern brands, for example, Husqvarna, Partner, Makita, Echo, Stihl, AI-92 gasoline is suitable. Today, just a huge number of people complain about premature failure of chainsaws due to poor gasoline. Therefore, some experts recommend 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 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.

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

Gasoline and oil for chainsaws. which is better

Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended that you read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.

Motor oils for two-stroke engines are produced by the following manufacturers:

Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

How much gasoline is stored

During long-term storage, gasoline evaporates (regardless of the brand), a sediment falls at the bottom, it loses its properties, in other words, it deteriorates. It is worth knowing that it is not the gasoline itself that ignites, but its vapors. Therefore, if there is a canister of gasoline in the garage since last year, then think, is it worth it?

  • increased wear of the engine parts of the chainsaw.

It is worth remembering that the prepared fuel mixture (gasoline with oil) is stored for no more than a month, after this time it should be disposed of. Using old mixture increases wear on the engine parts of the chainsaw. do not forget about it!

Why is gasoline mixed with oil for refueling chainsaws

It is necessary to dilute gasoline with oil in order to avoid the failure of the internal combustion engine. The reason for this is the design features of the lubrication system for two-stroke motors. In the design of such engines there is no chamber for filling engine oil, and if you fill in fuel without lubricant, then the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all the listed parts, therefore, it is prohibited to fill in clean fuel.

Gasoline and oil for the chainsaw must be poured in the appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. Lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, it is necessary from the first day of operation of the tool to fill it not only with high-quality materials, but also observe the correct proportions.

For the engine to work properly, the main thing is to fill it with clean fuel without contamination.

Chainsaw refueling instructions

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. Refueling instructions are as follows:

  • First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly.
  • Place the tool on a clean and level surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt.
  • The filler neck must point upwards.
  • Install a small watering can in the neck, then pour fuel
  • Control the refueling process, as the volume of the tank is small, so it fills up quickly
  • Do not fill up to the full maximum, since when the tank cap is closed, the remaining fuel will splash out.
  • After the fuel is poured into the tank, immediately add chain lubricant.
  • The consumption of fuel and chain lubrication is approximately the same, therefore, both tanks must be filled at the same time.
  • After refueling, you can start starting the engine

It is better to start the engine not in the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready for work, and you can start to start it. How the chainsaw engine starts, you can read in this material (link).

Gasoline to chainsaw oil ratio

The proportions of oil and gasoline for refueling two-stroke engines of chainsaws of different brands is 40 to 1 or 50 to 1. This ratio is standard, which is used not only by beginners, but also by experienced sawers. It is this ratio for preparing the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and piston.

How much oil should be poured into gasoline in milliliters? Calculated per ml, the ratio of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the correct mixture, you should fill 1 liter of gasoline in a plastic bottle and dilute it with 20 ml of oil. To correctly measure how much oil to pour, you should take a special measuring container and fill it up to the appropriate mark. If you plan to immediately prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios that different manufacturers offer. These values ​​of the ratios differ insignificantly, but if you have subtracted other values ​​in the instrument’s passport, then you need to adhere to them. A value of 1 in 50 or 40 is standardized. Pour 15 ml of oil into 1 liter of fuel in the summer, and in winter add at least 20-25 ml. Knowing the recipe for preparing the mixture, you should also figure out what kind of gasoline to pour into the chainsaw?
