Husqvarna chainsaw Which Gasoline

What happens if you don't dilute gasoline with oil?

For chainsaws with two-stroke engines, a mixture of oil and gasoline is used - this filling allows you to ultimately obtain more engine power without taking up a large volume, without creating a bulky structure. A two-stroke engine cannot run on pure gasoline, since as a result of the combustion of gasoline additives, rust will quickly appear on spark plug electrodes and nozzles, and fuel consumption will be very high.

Refueling a chainsaw

Suitable gasoline brands and their classifications

Modern manufacturers of chainsaws recommend using gasoline with an octane rating of 90 or more for all tools. For example, AI-92 gasoline. There are also references to AI-95 gasoline, but it is less popular because it is more expensive and contains a larger amount of methyl tert-butyl ether, an additive that reduces the risk of fuel detonation.

AI-92 gasoline consists of isooctane and n-heptane (92% and 8%, respectively). These two components balance each other in octane numbers, which means they are best suited for filling a chainsaw tank.

It is not advisable to use cheap gasoline or fuel that has been sitting in a canister for more than two months. Mixing gasoline with low-quality, cheap oil or waste oil is also unacceptable.

Alternative fuel option

To refuel household and professional chainsaws, it is recommended to use motor gasoline of the AI-92 type that does not contain alcohol components and additional additives.

The question of whether it is possible to pour 95 gasoline into a chainsaw remains controversial to this day. Theoretically, the anti-knock properties of AI-95 gasoline are higher than those of standard AI-92 fuel, but in practice it is better to give preference to the second option.

The problem is that in order to improve the anti-knock characteristics, manufacturers and distributors introduce additives into the composition of 95-grade gasoline, the quality and effectiveness of which raises reasonable doubts among experts.

Such fuel does not fully meet the required characteristics and does not have proper stability during long-term storage. After 3-4 months of exposure, its working properties deteriorate by 25-30%.

Suitable oil brands and their classifications

In order to dilute the fuel mixture for a two-stroke engine, the following types of motor oils are used: synthetic, semi-synthetic. It is not advisable to use mineral oils because they tend to harden at low temperatures and are more expensive. Recommended type of oil to add to gasoline to prepare the mixture: oil for two-stroke air-cooled engines.

Modern manufacturers of fuels and lubricants label oils by type: synthetic, mineral, semi-synthetic, so it will be difficult to make a mistake with the choice. Please note that European oil quality standards have been lowered, however the Swedish brand Husqvarna has kept the old standard as the benchmark. This is why the dilution ratio of Husqvarna oil with gasoline is lower than that of other brands of oil.

Recommendations for choosing gasoline

According to current standards, the best gasoline for a chainsaw should be unleaded, high-octane, and fairly fresh. A high degree of purification from foreign impurities is welcome.

Filling the fuel system with fuel that has been stored for more than six months has a negative effect on the traction characteristics of the internal combustion engine, promotes carbon formation and the occurrence of detonation phenomena.
It is advisable for beginners and experienced users to exclude from their attention low-octane gasoline for chainsaws, as well as cheap motor oils of unknown origin. The use of leaded fuel is not prohibited, but in order to extend the life of the saw, it is best to abandon its use at the selection stage.

Practice shows that saving on the quality and cost of consumables negatively affects the performance characteristics of chainsaw equipment and the duration of its full operation.

Mixing principle and proportions

Oil from all manufacturers, except Husqvarna, must be diluted in a ratio of 1:33, that is, the output will be a 3% mixture with the following composition: 30 grams of oil are required per liter of gasoline.

Husqvarna oil is mixed in a ratio of 1:50, the resulting mixture is 2%, which contains 20 grams of oil per liter of gasoline.

The tank volume of a chainsaw differs depending on the engine power and its capacity (in cc). The average capacity of chainsaw gas tanks is from 300 to 600 ml or more, oil tanks - from 200 to 400 ml. and more. The more horsepower the saw produces, the more gasoline is placed in the gas tank.

The average fuel consumption per hour for a chainsaw ranges from 257 to 380 g/kW/hour. The consumption of the gasoline-oil mixture depends on indicators such as the degree of load on the chainsaw, operating time without shutting down, the condition of the saw chain and bar, the smooth operation of the carburetor, as well as the model of the chainsaw.

For example, the latest generation of saws consume fuel more efficiently than older models.

Proportions of oil and gasoline for a chainsaw - preparing a mixture for refueling a two-stroke engine

Features of preparing the mixture

For safety reasons, it is recommended to prepare the fuel mixture in a metal canister that is not subject to the formation of static electricity.

The recommended proportions of gasoline and oil are individual for each model. In most options, this is a ratio of 50:1 and 40:1. Much less common are chainsaws that run on a gasoline-oil mixture in a ratio of 25:1.
According to manufacturers of branded chainsaw equipment, their products do not require running-in. However, during the first hours of operation, experts advise operating a new chainsaw on a fuel mixture with a high oil content and, if possible, in a gentle mode.

Containers with built-in dispensers are convenient for preparing the working mixture. The selectivity of fuel filters at gas stations, in some cases, leaves much to be desired, so it is recommended to filter gasoline through suede or non-fiber material.

Following these recommendations will eliminate spontaneous equipment failures associated with malfunction of the carburetor.

The specific characteristics of mineral or organic chain oil are aimed at lubrication and cooling of saw accessories, and therefore are not suitable for preparing a fuel mixture.

How long can the diluted prepared mixture be stored?

The standard shelf life of the prepared oil-gasoline mixture is 1 month. Chainsaw manufacturers recommend in their operating instructions not to prepare large quantities of fuel mixture. The best option is to prepare the mixture for operation and full production, and then refill with fuel if necessary.

It is generally undesirable to store the mixture in the fuel tank of a chainsaw for longer than two to three weeks. When not using the tool, it is recommended to drain the fuel and dry the tank.

Typical faults and repairs of Husqvarna chainsaws

Owners of Husqvarna chainsaws rarely experience breakdowns of their tools. However, if this does happen, then you can try to fix the problem yourself. Let's talk in more detail about how to identify a breakdown and repair a Husqvarna chainsaw without the help of a specialist.

How to adjust the carburetor on a Husqvarna chainsaw?

How to remove the clutch on a Husqvarna chainsaw?

Remove the air filter and unscrew the spark plug. If necessary, wipe the area around the chainsaw spark plug;
At the next stage, you will need to remove the sprocket from the Husqvarna chainsaw - this will make it possible to carefully inspect the mechanism for blockages;
The clutch coil is unscrewed in the clockwise direction. Under it there is a pressure washer, which also needs to be removed;
At the end, the sprocket is replaced and a new clutch is installed. Reassembling the Husqvarna chainsaw is performed in the reverse order.

The first few starts of the chainsaw engine will be accompanied by ringing sounds - this is due to the fact that the drive sprocket will rotate until it finally falls into place.

Oil does not flow to the Husqvarna chainsaw chain - reasons and solution

First, remove the protective cover and starter spring, after which the chainsaw air filter is dismantled.
Below it on the right side there is an oil pump, which needs to be inspected for cracks and other damage. If necessary, replace the pump;
If you notice that the oil hoses have moved away from their base, then they will also need to be replaced with new parts.

After installing new spare parts, you can continue working with the tool. In the future, use only high-quality oil from trusted manufacturers. The correctly selected sharpening angle of the Husqvarna chainsaw chain is also of great importance, since the speed of movement and the intensity of lubrication of the saw element depend on it.

Reviews from chainsaw owners about refilling the tool

Gena, Ulyanovsk:

“I want to share an important observation. It will be useful for owners of chainsaws originally from the USSR - the Urals or Druzhba. Previously, it was believed that such saws needed 50 grams of oil per liter of gasoline, and even 60 grams during break-in. Nowadays oils are of higher quality, so you can safely pour 20 grams per liter! This observation made it much easier for me to operate the chainsaw and eliminated excess oil. I recommend that everyone who has such “old saws” try this proportion for their tools.”

The ratio of gasoline and oil for a chainsaw: how and how much

From the very beginning of their existence, chainsaws have been gaining momentum in popularity and demand among consumers in various countries once a year (see the rating of the best chainsaws). And this is not at all mind-blowing, because they are irreplaceable assistants in the field of agricultural activities, cutting down trees, and are also successfully used in repair work. But, even without looking at their so-called popularity, they, like you and me, require attention and a typical approach.

This is especially true for the gasoline-oil consistency that you pour specifically into your “favorite”. Because this additive, namely its quality, directly affects the operation and productivity of the chainsaw.

In this article we will look at all the issues related to this necessary water. We will learn how to dilute gasoline with oil for a chainsaw, what proportion of oil and gasoline for chainsaws, and also what oil to add to gasoline for a chainsaw. What kind of gasoline to put into a popular brand of chainsaw. A chainsaw is a convenient unit that can solve a lot of everyday problems. What kind of gasoline should I put in my Husqvarna 137 chainsaw? It is better to use 92nd gasoline. In what proportion? So let's get started.

Device Aspects

At this point, we will “plunge” into the very core of this tool, so that you can at least have a general idea of what your “assistant” consists of. In fact, this kind of tool can be responsibly attributed to traditional mechanisms that work as a means of activating a gasoline engine.

Two-stroke engine Without exaggeration, we can say that this type of tool is the simplest of all other mechanisms , because the saw does not have a gearbox and is armed with an ordinary two-stroke engine, which has one cylinder and runs on gasoline.

The main advantage of a chainsaw is that it is designed quite easily, which helps to increase reliability and trouble-free operation in difficult and difficult conditions. Next, let's look at the design of the saw in more detail, so:

engine;
clutch;
ignition system;
carburetor (see carburetor adjustment);
fuel system;
air cleaning system;
starter;
chain (see how to sharpen a chain);
tire;
chain brake;
chain tension mechanism;
chain lubrication system (see chain lubrication oil).

In essence, we have sorted out the device, but now an important issue remains the lubrication of the chainsaw parts. Many people do not understand why it is needed at all? The answer is quite simple, like all mechanisms, a chainsaw, especially its individual parts, require special care, including periodic lubrication.

This is necessary in order for your tool to serve you for many years , since during operation the chainsaw spare parts produce a movement that must be smooth, smooth, so as not to damage nearby spare parts.

First of all, what I would like to draw your attention to is the fact that almost all chainsaws have a carburetor two-stroke engine. And also in their “arsenal” there are two direct tanks, namely: gasoline and oil. In order to choose oil for a chainsaw, you need to know certain criteria for this type of choice.
Firstly, do not forget that, for example, domestically produced chainsaw models require the use of only simple oils that are used directly for motorcycles, and tools that are manufactured abroad require branded oils, since their requirements are significantly overstated.
In fact, if you look at it this way, then only you, as the owner of the equipment, can determine which oil to use.

Unleaded gasoline The first, so-called additive, is unleaded gasoline , which has an octane number of at least 92. What kind of gasoline should be poured into a chainsaw. The green tint oil is premium. For example, AI-95 and AI-92 gasoline will serve excellently for this purpose. The second component is a specialized oil intended specifically for gardening equipment with a two-stroke engine.

Now we will figure out what ratio of oil and gasoline is necessary for a chainsaw, since this issue must be approached with all responsibility. So, in most cases, for one liter of gasoline itself you need somewhere from twenty to fifty milliliters of oil.

And if you are concerned about the question of how much oil to pour into gasoline for a chainsaw, which has an immediate power of about 1.5 kW, then in this case you will need 25 ml of oil per liter of gasoline.

For significantly more powerful instruments, about 30 ml is usually used , and sometimes even more.
