Husqvarna Chainsaw Components

The fuel system and the lubrication system of the chainsaw Husqvarna 365, 372

Husqvarna 372 XP chain carburetor adjustment allows the engine to adapt the engine to local criteria, such as climate, height above sea level, gasoline quality and oil type for two.stroke engines.

The carburetor is equipped with three adjustment capabilities:

L = low.speed stream. H = high.speed stream. T = idle adjustment screw screw.

In the nozzles L and H, the amount of fuel is adjusted so that it corresponds to a clock of the air supplied by the throttle of the gas handle.

If the nozzles are wound clockwise, the mixture will be bad (less fuel in relation to the amount of air), and when the nozzles are unscrewed counterclockwise, the mixture will be richer.

The poor mixture gives more speed and a richer mixture. Lower speeds. How the Husqvarna carburetor is configured? Screw t regulates the position of the damper at idle.

If the screw T is rotated clockwise, the idle speed will increase, and if the screw is turned counterclockwise, the number of revolutions will decrease.

Pre.install and turn on the Husqvarna 365 XP chainsaw

When inspecting the work at the factory, the carburetor was pre.adjusted. Preparatory adjustment: n = 1 turnover, respectively l = 1 turnover.

So that the details of the Husqvarna saw engine receive sufficient grease (breakdown), the carburetor is configured for a small reboot of the fuel consistency during the first 3-4 hours of operation.

For this installation, the maximum speed is set at 6-700 rpm below the recommended.

If it is impossible to check the maximum speed using a tachometer, nozzle N should not be installed on the fuel mixture under the preparation unit.

Do not exceed the maximum number of revolutions. Carburetor adjustment on the Husqvarna chainsaw is the main node for the chainsaw. If the chain of the chainsaw rotates at idle, then, turning the screw t counterclockwise, it is necessary to achieve its complete stop.

Run the chainsaw and let it go for about 10 minutes.

Place the Husqvarna 365 chain saw on a flat surface so that the saw strip is directed to the opposite side of you and that both the tire and the chain are in contact with the surface.

Find the maximum idle speed, slowly turning the low.speed stream clockwise and counterclockwise.

When the maximum speed is found, turn the stream L counterclockwise 1/8. 1/4 turnover.

Accurate idle speed adjustment using the screw t

The idle stroke is installed using a screw indicated by the letter t.

If adjustment is required, then the idle screw t should be rotated clockwise until the chain starts to rotate.

Then turn the screw counterclockwise until the chain stops.

The number of revolutions is considered correct in which the chain saw engine works smoothly in all positions with a sufficient margin to the number of revolutions in which the chain begins to rotate.

Under the brands

For modern brands, for example, Husqvarna, Partner, Makita, Echo, STIHL, AI-92 gasoline is suitable. Today, just a tremendous number of people complains of premature failure of chainsaws due to poor gasoline. Therefore, some experts recommend filling AI-95 in such chainsaws.At the same time, a good AI-95 can “burn the piston”, and again a certain number of people have found a compromise and mix AI-95 with AI-92. In general, it all depends on the quality of gasoline and ultimately decide.

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

We make a mixture: important proportions

When using a two.stroke engine, pure fuel is purchased separately and mixed with oil, often in 1:50 proportions. In such a engine, it is constructively impossible to install an oil pump, so it is strictly prohibited from pouring pure gasoline in a chainsaw! Proportions, quantity and some brands manufacturer indicates in the instructions for the operation.

Important points in the preparation process:

  • Domestic chainsaws work with M8-V oil, M-12TPU, M8-V, TP, MGD-14M. In some cases, you can use foreign options;
  • Proportions: 2.5 l of gasoline FI-80 per 100 grams of oil;
  • Foreign models have a minimum fuel consumption. They work on foreign oils, and their proportions become 1:40 or 1:50.

The principle and proportions of mixing

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

Husqvarna oil is mixed in a proportion of 1:50, the output is a mixture of 2%, which includes 20 grams of oil per liter of gasoline.

The volume of the tank of the chainsaw is different based on the engine power and its capacity (into the cube.cm). The average capacity of the gas tanks of the chainsaws is from 300 to 600 ml or more, oil tanks. from 200 to 400 ml. and more. The more horsepower the saw gives out, the more gasoline is placed in a gas tank.

The average fuel consumption per hour is from 257 to 380 g/kW/hour. The consumption of a gas.powder mixture depends on indicators such as the degree of load on the chainsaw, the time of operation without turning off, the condition of the saw chain and tire, the coherence of the carburetor, as well as the chainsaw model.

For example, the latest generation saws consume fuel more economically than old models.

What an accurate rate of the lubricant is required for the preparation of the combustible mixture necessary for the normal operation of a two.stroke gasoline internal combustion engine? Buyers will learn about this from the applied instructions to the goods. But documentation is often lost among papers. In this regard, information will not be superfluous reminders. manufacturers for mixing gasoline use transmission grease. The Swedish company is known on all continents of the planet delivered to trade markets with reliable goods. Husqvarna chainsaw oil is used strictly recommended by the manufacturer.

Depending on what power it is required to obtain from the units, the corresponding component dilution is chosen:

In one liter of fuel, from 40 to 50 parts of oil are diluted. These are perfect proportions of gasoline and oil.

Along the way, we report that only unhealthy gasoline of the AI-92 or AI-95 grades is used. Ethylated combustible product is considered an unsuccessful choice for the internal combustion engine, since it shortens the operational resource of the engine.

Husqvarna HP structural company

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

The manufacturer for the chainsaw Partner has developed an original ratio of the proportion of fuel and oil for two.stroke power plants:

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

There are moments of non.compliance with a standard approach to diluting the company’s own production of own production by a lubricant. This is when the ICE passes the stage of the run.in. A combustible mixture in the value of 1:40 is allowed for the engine.

Proportion for chainsaw Friendship

The genealogy for the chainsaw of friendship began in 1953 by the development at the ZMKB “Progress”. The production of goods was entrusted to two enterprises. the Siberian Instrument.making and Perm Engineering Plants. The mass production of a mechanized product has begun, which is still in the trend of the day, since the unit has been systematized.

The engines use fuel low octane numbers. The unit shows the highest productivity when filling the AI-76 and AI-80 gas stamps in ICE of 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 dilute the fuel with two.stroke oil in a ratio of 1:50. That is, fuel is diluted with 20 milligrams of oil.

We need high.quality components

Practice proves the influence of the quality of the prepared mixture, taking into account the necessary proportions on the operational period of use of the tool, power, performance:

  • It is not recommended to use the components that have completed the shelf life.
  • It is especially important for the components of gasoline and oil. not to use the components obtained on the basis of gas condensates, since the molecular structure contains harmful, for ICEs, rush and water and water.
  • Partial discrepancy between AI-92 international standards. AI-95 brand is saturated with additives that extinguish the detonation moments.

The noted deficiencies limit in time the operational resource of manual chainsaws, the ICE of which work at complex consistency of the combustible mixture.

What will happen if you fill in the surgery in the chainsaw

If you do not want your chainsaw to refuse at the wrong time, use exclusively high-quality fuel and lubricants. Mixing with gasoline is prohibited. The reasons for this are the following factors:

  • Another viscosity of the material, therefore, working out is not able to provide effective lubrication of rubbing parts and mechanisms
  • The development contains small particles of metal and chips, which getting into the tank, will result in clogging the fuel filter and channel. If the lubricant enters the cylinder along with small particles, then they will leave their mark in the form of accelerated wear of piston rings
  • Highlighting a large amount of black smoke, which indicates the combustion of oil

Surrogate materials cannot be poured not only in a tank with gasoline, but also in a tank for lubricating the chain. What will happen if you use working out in the tank for lubricating the chain, you can see on the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaws will work. With improper dilution of the fuel mixture, not only the resource of the tool is reduced, but also its performance is reduced.

Talking about what or unique tools, trying to reflect its convenience or ease of use, we use the epithet “Continuation of the arm”. The 1st that comes to mind at the mention of the chainsaw is pronunciation, in fact, the continuation of the hand. Gasoline for a chainsaw: how to fill in Husqvarna. Only the successful ergonomic of the pen is the dignity of these saws? Let’s try to figure it out.

Husgvarna released the first chainsaw in the fall of 1959, having made a techno revolution in this field. Not being the “parent” of the first chain chainship, the Husqvarna enterprise stood at the origins of its invention and is the creator of the layout of modern saws. Many technical solutions, for the first time used on the Husqvarna chainsaws, over time have become an indisputable attribute of all saws, forcing them to revise and change the technical requirements for saws and non.hazardous work, in fact in the world.

The Husgvarna chain of chainsaws is represented by both household and profiles, with difference, as in at least some kind of complex tool, in power, reliability and duration of work. Therefore, if you choose a saw, then you should know why it is for you, but if you are a happy owner of such a technique, then how it is true to operate.

The security chainsaws are even stronger than household and have a power spectrum of 2.7 to 8.2 liters.With.(2-6 kW), made with overstated strength and wear resistance, with a total working resource of performance up to 2000 hours. All Husqvarna chainsaws have a gasoline two.stroke engine that feeds on the consistency of high.octane gasoline and special oil, in a ratio of 1:40 to 1:50, is indicated in the passport for each model. The use of high.quality gasoline, special 2t oils and forged three.section crankshaft, allowed the manufacturer to get not only the endurance of the motor in the most languid criteria, and not a poor ratio of weight and power; For comparison, the weight of the 1959 standard saw was 11.5 kg and 4.6 kg at the Husgvarna 142 model. Oil pump for a chainsaw China GC99458 But I do not know how to replace, extract an oil pump. Two tanks of chainsaws, for fuel and oil, provide the operation of the motor and grease the saw chain, while the tanks are designed so that with the full production of combustible, chain lubricant is not much left. Do not try to “save” using the lower, from the recommended, gasoline and oil, as they are not designed for the highest revolutions of the chainsaw, burn out without lubricating the rubbing parts and lower the service life of the motors by 15%. It is allowed to use motor oils for lubricating the saw chain, and here it is better to use passport oils.

The choice of fuel

What to choose fuel for a chainsaw is an ostrough question, the successful of the unit is directly dependent on it. According to available canons, good gasoline for a chainsaw is considered not ethylated, but highly octane from a tested manufacturer. The cleaner fuel, the better. If gasoline was stored in the canister of a year and a half, then this will negatively affect the disposition of the device, therefore, the substance should be prepared before the start of work.

Fundamentally track out so that there is no alcohol in the combustible, any additives that may violate the functioning of the power plant. Specialists are still conducting discussions, which is better than 95 or 92. The 1st has more stable detonation characteristics, but in most cases all the same use the 92nd. The reason is ordinary: questions often appear to the 95th, it has a huge number of different additives that have a poor effect on the work of the saw engine. Microdetonation appears (piston pulse into return), which takes place in fact with each turnover of the crankshaft. If the octane number is even larger than the highest (98), then microuders will become even more saturated.

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

Recommendations on the components

Even the holder of the chainsaw, even observing the proportion to the gram, can harm his instrument if he uses low.quality or unbearable components. The general recommendation is the use of special liquids.

Two words about oil.

Oil for two.stroke engines is produced mainly for a gasoline tool. It is always painted in some bright color-blue, green, red, pink. This is done so that when adding to gasoline it becomes clear that this is a ready.made mixture that can already be poured into a gas tank. Large manufacturers, for example, STIHL, have several types of oils that differ in color.

If you have a saw to which the oil of the same manufacturer is recommended, listen to this recommendation if you are a beginner. Only experimental “pilots” find the very oil that suits them the most by the method of trial and errors.

Do not lie on a two.stroke engine motor oil for cars! Although the Internet is full of reviews of those who say “Lew, and the flight is normal”, believe me: they have not yet shown the master piston of their instrument. And smoke from the muffler is unlikely to delight you.

and about gasoline

Say that in oil producing and processing gasoline basically poor quality means to repeat the obvious. You can “get” on bad fuel not only at nameless gas stations, but also on large gas stations with a loud name. High.quality gasoline is very important for modern high.tech chainsaws. it allows them to work with maximum return and minimal wear. The general requirement for today is the use of gasoline with an octane number of at least 92. It has optimal indicators for chainsaws.

In old Soviet units, 76th gasoline could be poured. Today you should not do this even with cheap Chinese saws. you will only accelerate its “death”. It is also not recommended to fall into another extreme-pour the 95th or even 98th in an expensive tool, thinking that it will be better from this.

Arkady, 39 years old, consultant of a chain store

We recommend pouring 92nd gasoline on two-stroke engines, bought in proven places, which you have no doubt. Buyers come and ask: the better gasoline, the better the saw? Why then not to pour the 95th? After all, more advanced cars require only it.

Husqvarna Combi Gas/Oil Can Review

Answer: Most of gasoline 95 is the same 92nd, but with additives that reduce detonation. This parameter is not important, it needs the most pure gasoline, since the additives are completely superfluous. Therefore, the logic is simple: it is better pure 92nd than the more expensive 95th, but with unnecessary additives.

What will happen if you fill in the surgery in the chainsaw

If you do not want your chainsaw to refuse at the wrong time, use exclusively high-quality fuel and lubricants. Mixing with gasoline is prohibited. The reasons for this are the following factors:

  • Another viscosity of the material, therefore, working out is not able to provide effective lubrication of rubbing parts and mechanisms

Surrogate materials cannot be poured not only in a tank with gasoline, but also in a tank for lubricating the chain. What will happen if you use working out in the tank for lubricating the chain, you can see on the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaws will work. With improper dilution of the fuel mixture, not only the resource of the tool is reduced, but also its performance is reduced.

What parts of the chainsaws need oil

The quality of the lubricant directly determines the engine resource. Despite the small operating volume, the matts of the chainsaws are operated relatively strongly. Inertial loads on the details of the crooked-shaped mechanism are proportional to the square of revolutions. Since most of the gasoline tool most often works on “full gas”, oil for the chainsaw should retain its properties at high shift speeds, prevent dry friction in the crankshaft bearings and the piston group.

In addition to the engine, the tire needs a lubricant: the sliding chain inevitably wears it out. Forced supply of oil from a separate tank saves the resource at the tire and at the very chain. The oil used for lubrication should be as viscous and sticky as possible, so that it is better to stay on the chain and tire, not to fly apart. In addition, according to environmental requirements, such oils are usually biodegradable.

How to mix oil with gasoline

Motor oils are used to add to gasoline for a trimmer for grass. Mixing is carried out in a certain proportion. Manufacturers have a voluminous ratio of different: from 1 to 50 to 1 to 20. In the technical specifications, the link to this is. You should be careful with a small shared participation of oils. Most often it is 1 to 50 (20 grams of oil per liter of gasoline). How much does a trimmer cost for grass. Slight inaccuracy leads to oil starvation of the engine, reduces its resource.

husqvarna, chain, mixture, composition, fuel, chainsaw

There are products that indicate the proportion 1 to 20-40. It is better to refuse such a lubricant. The wide range of the mixture indicates the low qualities of the product. Resting piston rings, with constant use of such varieties, is practically guaranteed.

Motor oils, such as M.8, are added to the proportion of 1-20. In high.speed engines, their use is undesirable. The cycle between the supply of the mixture is so small that it will cause an excess of lubrication in the cylinder. Trammers for grass have small speeds, so they allow the use of low.grade lubrication. Due to the initially low resource, you can not worry about the lawsuit of the rings. gasoline and oil for how much oil to pour in 25 ml of oil per liter. Previously, a complete wear of equipment will occur.

The use of recommended oil or from other manufacturers is not fundamental. The main thing is to dilute gasoline with oil for a trimmer for grass in compliance with proportions in accordance with the characterization of the product. The refusal of service workshops in warranty only on the basis of the use of lubricant of another brand, but with acceptable parameters, is illegal.

Husqvarna oil for air filters

The assortment is represented by one product Air Filter Oil. This is a pale yellow liquid with a characteristic smell. Supplied in opaque cans of white color with a capacity of 1 liter. The product guarantees the effective capture of particles balanced in the air, and prevents them from entering the combustion chamber.

Chain oil

The saw set is not lubricated with motor oils. For this purpose, a special fuel for a chainsaw is used, which is characterized by the highest adhesion to the surface. Chain oil lowers friction and wear of parts that come into contact with.

Modern stamps of chainsaws have a tank on the body, in which chain oil is located, so that the saw set is lubricated with automatically.

At one time, the tools of the tool in the gap of the cool season choose a semi.synthetic synthetic oils in another way, at one time a warm. mineral.

On some stamps of oil, you can meet the marking of Ces, which says that in fact, that they are made on a plant base do not harm the environment.
