Husqvarna 340 chainsaw - general purpose all-rounder

The Husqvarna 340 petrol saw, popular among gardeners, belongs to the class of amateur garden tools. It has solid power and high endurance, which allows this model to successfully cope with cross-cutting logs, cutting thick dry branches, clearing wild bushes and felling small fruit trees. Modest weight, good ergonomics and a correctly set center of gravity make this model a reliable assistant for performing various jobs at height.

Putting the chainsaw into operation

Before starting a gasoline saw, it is necessary to fill the tank intended for this purpose with oil to lubricate the chain and prepare the fuel mixture.
It is mixed in the ratio recommended by the manufacturer. For various models of Husqvarna chainsaws it is 1:40 or 1:50. This means that for each liter of AI-92 gasoline, 25 or 20 ml of special oil for two-stroke engines are added with intensive stirring. After filling the fuel tank, the chain tension is checked. It should not sag or move with excessive force. In practice, to check it, it is pulled up in the area of ​​​​the middle part of the tire. In this case, the chain may come out of the groove by 2-3 mm. The necessary adjustment is carried out with a special key.

To start the Husqvarna saw, it is placed on a horizontal platform that is clear of foreign objects. The sequence of actions will be as follows:

• the chain brake is activated by moving the protective shield forward in the area of ​​the front handle;
• the cylinder decompression button is pressed;
• when the engine is cold, the choke control is fully extended; when the engine is warm, this is not necessary;
• The saw body is fixed by pressing the right foot on the rear handle and holding the front handle with the left hand;
• sharp jerks of the starter handle achieve a short-term pickup of the engine, after which it will spontaneously stall;
• the air damper regulator is recessed into the housing, then the starter is driven again until the engine starts;
• the saw is taken with both hands into the working position, and the chain brake handle is moved to the working position;
• Before starting work under load, it is recommended to make sure that the chain lubrication system is working; to do this, press the throttle to increase its rotation speed to the maximum, then droplets of oil should splash around the far end of the bar.

Classification of branded model range

Husqvarna gas-powered saws, taking into account the drive characteristics and duration of continuous operation, are divided into three categories.

• Amateur class models are designed for on-farm work on harvesting wood fuel, crowning trees and preparing building wood materials for installation.
• Semi-professional saws are characterized by increased productivity, a comfortable level of operator work, and the ability to work with wood of different diameters.
• The wide functionality of professional-level models is complemented by stable resistance to operating loads. Professional saws from Husqvarna are successfully used in industrial logging.

Answers to frequently asked questions

The Husqvarna 340 chainsaw requires careful handling. Violation of operating rules leads to changes in adjustments and even breakdowns, but some malfunctions can be eliminated with your own hands. Let's take a closer look at how this is done.

What tires can be installed on a Husqvarna to replace a faulty one? First of all, the technical parameters must match. The tire length is 13-18 inches (33-45 cm), the groove width is 1.3 mm and the maximum number of driven sprocket teeth is 10.

Why does the Husqvarna 340 chainsaw chain lubricant flow in a stream? The answer here, as a rule, is one - the seal of the oil pump or the interface between the oil supply hose is worn out to the limit. You can learn more about this by watching the video.

Many inexperienced users are interested in how to adjust the oil supply for chain lubrication. There is an adjusting screw at the bottom of the chainsaw. Turning it increases or decreases the oil supply to the chain. How this is done is shown in the video

How to remove the sprocket on Husqvarna 340? The process of removing the drive sprocket is not a simple one. To perform this work, it is necessary to remove the clutch along with the drum. How to do this is clearly shown in the video.

Having experience in performing plumbing work and tools, knowing the structure of a chainsaw, it will not be difficult to replace the sprocket on the Husqvarna 340 yourself.

Advantages and disadvantages

The quality and reliability of the Husqvarna 340 chainsaw, as well as a long two-year warranty, are noted by a large number of positive consumer reviews.

• First of all, it is affordable. Despite the high level of modernization, the actual price of the model has increased slightly.
• Installing an automatic carburetor helps stabilize traction characteristics, regardless of temperature, load and other external operational factors.
• There is a fairly wide assortment of spare parts that are unified with the same type of models, allowing you to carry out simple chainsaw repairs with your own hands with the proper quality. Thus, it is possible to reduce the time of forced repair downtime to a minimum.

Many users consider the disadvantages to be the high cost of branded consumables and the need for complex repairs in service centers.

In a number of cases, service specialists practice replacing worn-out branded parts with cheap Chinese analogues, without agreement with the customer. The price range of Chinese-made spare parts is lower, but their quality is still insufficient.

During self-repair, many problems are created by the chain drive drive sprocket, to replace which you have to completely dismantle the entire clutch assembly. The instructions contain incomplete information on setting up fuel equipment.

And

The use of a catalytic afterburner of exhaust gases, E-TECH technology, reduces their toxicity, is approved for use in all countries and allows us to talk about a qualitative improvement in working conditions. Gasoline for a chainsaw - what kind to pour? How to dilute gasoline for a chainsaw? (Husqvarna). We must pay tribute to the fact that Husgvarna always prioritizes improving the working conditions of its tools. The 1959 saw had the lowest noise level compared to other saws, and since 1973, all saws have had an automatic chain brake to protect the saw operator from kickback. Modern chainsaws use a combined chain brake, which stops both manually - by resting your hand on the guard - and automatically, by the force of inertia of the saw's recoil. What oil to use for what oil to pour into gasoline for and husqvarna - for. Many manufacturers, to prevent kickback, eliminate the possibility of working with the toe of the saw and install a limiting shield. But Husqvarna saws do not have it, since Swedish safety standards allow working with the end of the bar. The ratio of gasoline and oil for a chainsaw: how and how to dilute gasoline for a chainsaw? In Russia, only first-class fellers are allowed to work in this way.

In 1969, Husgvarna released a chainsaw with reduced vibration levels and since then its saws have been equipped with anti-vibration systems, the quality of which is gradually improving with the release of each new model. Today, the company installs the LowVib vibration damping system on saws, the principle of which is to balance one mass with another, the inertial interaction of two masses. The chainsaw parts are isolated from the handles by steel springs, and the total mass of the handles is the counterweight. But keep in mind that the quality of vibration damping on household saws is lower, since their operating time is much less than professional saws. It is impossible not to note the double air filtration, which allows you to increase the productivity of the logger and the engine, by reducing the time for servicing the chainsaw. How to properly refuel a chainsaw, prepare what fuel to use. How to dilute gasoline for a chainsaw? The narrow body, high center of gravity and flat bottom make the operation of Husgvarna chainsaws convenient and comfortable.

And the last piece of advice is suitable for all chainsaws, without exception. Don’t forget that according to statistics, approximately 90% of all saw breakdowns are the result of careless handling of the saw set and chain. If the chain is sharpened, then it works, and if not, then it is a person. You put more effort into sawing, increasing the load on the chainsaw, reducing the service life and the entire service life of the unit.

Husqvarna petrol saws are in great demand both among novice gardeners and experienced forest fellers. Models of the Swedish brand have a number of important advantages such as reliability, balance and high working life. Moreover, each Husqvarna chainsaw has a simple design, which makes it easy to maintain and quickly fix any breakdowns that occur.

Owner reviews

I respect Husqvarna chainsaws from previous years, in particular the 340th model, for their reliability and stable performance characteristics. According to many of my colleagues, the quality of new developments from this brand has decreased significantly in recent years. If I don’t get a new chainsaw like my 340 version, I’ll look for an analogue in the Shtilev assortment. Alexander Fedorovich

There is a limit to every perfection. In my case, this is an automated carburetor of the Swedish Husqvarna 340 chainsaw, produced last decade. Perhaps I came across a defective copy, but the device is capricious and capricious in all respects; even experienced craftsmen are reluctant to set it up. In all other respects the car is excellent. For sawing oak and other dense wood, I use a chain with carbide links. I didn’t have to cut the aerated concrete myself, but I saw how it was done when installing the walls of an aerated block house. Zhenya

Peculiarities

Among its competitors, the Husqvarna 240-16-inch chainsaw stands out due to its ergonomics and workmanship. The parts of its body are made of high-strength plastic, which is not afraid of contact with gasoline or oil. They all fit perfectly and the chainsaw looks like a single unit.

The chainsaw is well balanced and has a convenient location of controls.

The main features of the model include the presence of the following innovative developments from Husqvarna:

1. Anti-vibration system consisting of reliable metal shock absorbers, which has a patented name LowVib;
2. A system that combines throttle position and engine shutdown control;
3. Air purification using a centrifugal Air Injection system;
4. Last, but most important, is the X-Torq system, which will be discussed in more detail below.

Adjusting carbohydrates with a Husqvarna chainsaw

Like all other saws, Husqvarna has the same carbon tuning algorithm. Therefore, the instructions will be relevant for other tools and models of chainsaws, such as Husqvarna 142, 236.

READ Metabo Lever With Speed ​​Adjustment

Before starting work, make sure the air filter is clean and all other components are working properly. Fuel supply to the float chamber should be running smoothly and the ignition system is set correctly with a new spark plug.

• Reset carbs to factory settings. Do this with the engine stopped.
• Now you can start the engine and be sure to warm it up for a few minutes. Adjustment of the XX Husqvarna 137 carburetor is carried out only on a warm engine.
• Turn screw L clockwise to set engine speed to maximum, then turn back a quarter turn. Use screw T to adjust the crankshaft speed to keep the chain from rotating. It should not move without pressing the gas pedal.
• Now you need to set the maximum speed and power. It is enough to connect the tachometer to the ignition system and set the maximum possible speed using the accelerator. Compare them with your passport data. If they are different, loosen or tighten screw H. By changing the range, you can create restrictions on the efficient operation of the saw and extend the life of the motor.

What you should pay attention to?

Once you have completed your Husqvarna carburetor adjustment, you should ensure that the engine is stable and the saw can easily lift and slow down to the required speed. The idle rotation is considered abnormal, so it is necessary to readjust its connection to the clutch using screw H.

Remember that the device is not set up right away: you will have to wait a while, as the Husqvarna chainsaw does not immediately respond to changes in the position of the screws. This time can range from 5 to 15 seconds. The table does not indicate this time, so you can only find out experimentally.

If a large amount of smoke appears during adjustment, it is necessary to adjust the flow of the fuel-oil mixture. To do this, turn screw L.

What are the factory settings for a Husqvarna chainsaw carburetor?

To start the chainsaw, even if it is not installed correctly, the factory settings of the H and L screws are used. Most Husqvarna chainsaws can be started by unscrewing both screws exactly one and a half turns. Only then can the position of the propellers be changed to achieve the required fuel consumption and maximum efficiency. XX is also adjusted after these manipulations.

If you still have questions about setting up the carburetor for the Husqvarna 137 chainsaw and other models in this line. I recommend watching this video:

So let's get started!

What is still useful for you?

• Firstly, a summary of the operation of the device itself.
• Secondly, the tachometer. Why exactly it will be useful to us, we’ll look at it a little later.
• Thirdly, a screwdriver.

Surprisingly, this is all we will need.

First, take a close look at the structure of your saw. What you need to do first is find where the carburetor jets are located, and what is even more important than the jets is the adjusting screws. Usually there should be two or three screws. One of them regulates idle speed, and the other two regulate low and high speed.

Specifically, you will need to adjust them, or tighten them, or unscrew them in order to enrich or lean the fuel mixture.

If you need to lean the mixture, then simply turn the regulator clockwise; if you want to enrich it, then turn it counterclockwise.

To adjust the idle speed, the screw that is responsible for this also needs to be turned clockwise in order to increase the speed, or, as you already guessed, in the opposite direction to reduce them.

Chainsaws Partner – troubleshooting and troubleshooting

Like other household equipment equipped with an engine, Partner brand chainsaws require repairs from time to time. This may be due to improper operation of the saw, or to simple wear and tear of spare parts. Be that as it may, the chainsaw needs to be repaired, and it is quite possible to do it yourself.

How to refuel a Partner chainsaw?

As the instructions indicate, to refuel the Partner chainsaw you should use gasoline of at least AI-92 grade. It must be mixed with oil designed for 2-stroke engines.

The optimal ratio of gasoline and oil for a Partner chainsaw is 50:1, that is, 20 ml of engine oil should be diluted in 1 liter of gasoline.

How to set the ignition on a Partner chainsaw?

If you cannot understand why the Partner chainsaw does not start, then first check the ignition system of your tool. Checking and adjusting the gap looks like this:

• First of all, remove the cover to which the starter is attached. To do this, we recommend using a T27 hex bit, tools included with the chainsaw, and additional attachments;
• Carefully inspect the ignition coil, flywheel with magnets and, especially, the gap between these parts. To do this, use a specially designed gasket;
• Installing the ignition on the Partner chainsaw is done by turning the screws, which brings the coil and flywheel closer to each other.

How to remove the clutch on a Partner chainsaw?

Repairing the tool clutch is often required in cases where the Partner chainsaw starts and stalls when you press the gas. However, not all novice gardeners know how to remove the drive sprocket from a Partner chainsaw. You can do this in this order:

1. First turn the lever and remove the saw chain brake cover;
2. Unscrew the nuts securing the clutch system using the wrench from the Partner chainsaw kit;
3. Remove the clutch from the chainsaw and completely disassemble it. If necessary, replace worn parts and clean the walls of the standard clutch elements.

How to replace the oil pump on a Partner chainsaw?

If you find that the chain on your Partner chainsaw does not spin, then the cause of this problem most likely lies in the wear or breakdown of a separate pump designed to pump lubricant to the chain. The design of the oil pump includes 2 elements - a storage chamber and a working part. Repairing the pump involves disassembling the mechanism, but it is not recommended to take any actions with its working part. The next steps are as follows:

1. Carefully inspect the inlet and outlet tubes through which the lubricant passes - as a rule, all pump malfunctions are associated with them;
2. If the channels are clogged, then all debris must be removed. simultaneously blowing them with compressed air;
3. If cracks appear on the channels, they need to be replaced;

If, after assembling the Partner chainsaw, the lubricant again does not pass to the saw chain, then the pump will need to be completely replaced.

How to adjust the carburetor on a Partner chainsaw?

Setting up the carburetor of Partner brand chainsaws is slightly different from the procedure with chainsaws of other brands. The difference lies in the markings and meaning of the adjustment screws. For adjustment, the manufacturer equipped the Partner chainsaw with three screws - the left fuel quantity screw, the right fuel quality screw and the “T” idle speed adjustment screw. All these screws are located on the left under the top cover of the chainsaw body. Adjusting the Partner chainsaw carburetor is as follows:

1. Remove the cover and clean the parts underneath;
2. Unscrew both screws fully clockwise and then turn them 1/5 turn in the opposite direction;
3. Start slowly turning the quantity screw until you hear the motor start to run at its highest possible speed. Immediately after this, turn this screw ¼ turn in the other direction. As a result, the Partner chainsaw should hold idle speed steadily;
4. Next, use the quality screw to set the maximum speed for the Partner chainsaw.

Do-it-yourself disassembly: nothing complicated

First of all, you need to prepare a place for disassembly. This could be a workbench or a regular table. In addition, you need a rectangular piece of fabric or cardboard - on it you will carefully fold the carburetor parts. And finally, a tool: for disassembly you will need a set of open-end wrenches and screwdrivers, a special cleaning compound and an ultrasonic cavitation bath.

Chainsaw carburetor repair tool

First, you will have to dismantle the chainsaw carburetor. This is done in this order:

To get to the carburetor, you need to remove the top cover of the chainsaw, secured with three bolts.

Removing the carburetor cover

Removing the fuel hose and drive rod

Removing the throttle cable

After removing the gasoline hose, the carburetor is ready for disassembly

The carburetor must be disassembled in the order prescribed by the design and functional solutions of its elements. The parts of the chainsaw carburetor do not differ in size, so you need to fold them carefully and in order, trying not to lose anything.

Disassembling a chainsaw carburetor in the photo

After disassembly, it is necessary to carry out troubleshooting and replace damaged or worn parts. Next, the entire set should be washed with a special product, dried and wiped with a dry lint-free cloth. The jets and tubes of the assembly must be purged with compressed air, or, in order to more thoroughly remove formations on their internal surfaces, they must be treated with ultrasound beforehand.

Scope of application

The powerful, semi-professional chainsaw Husqvarna 340 can rightfully claim the status of a multi-purpose universal tool.

This model is focused on a wide range of economic work related to the procurement of fuel wood, crowning fruit and ornamental trees.

The list of tool capabilities also includes pre-assembly, transverse and longitudinal-radial cutting of construction wood, sawing of foam and gas block building materials.

The presence of special attachments allows you to use the chainsaw as a grinder, ice drill, plane, compact and efficient pump.

Analogs

In the power category from 2.5 hp. Chainsaws from leading manufacturers STIHL MS 230-14, ECHO CS-3700ES-15 and AL-KO Solo 643 IP compete with the Husqvarna 340 model with varying degrees of success. The lack of a developed service network negatively affects the popularity of chainsaws identical in purpose to the Italian brand Oleo-Mac and other popular brands.

How to properly adjust a factory saw

Carburetor adjustment is divided into two main stages. The first one is called basic. It is performed with the engine running. The second is performed when the engine is warm.

First stage

The adjusting screws for the highest and lowest speeds should be moved clockwise until the highest resistance is met. When the screws reach the stop, you need to move them in the opposite direction and leave them 1.5 turns.

Main stage

The engine is turned on at medium speed and warms up for about 10 minutes. The screw responsible for adjusting the idle speed should move clockwise. It is released only when the engine reaches stable operation mode. It is necessary to ensure that the chain does not move during this process.

In idling mode, the engine may stall (the reason is here). In this case, you must immediately turn the adjusting screw clockwise until it stops. Sometimes the chain starts to move. In this case, turn the adjusting screw in the opposite direction.

Checking acceleration operation

Need to do a little research. Acceleration of the device is initiated. It is necessary to evaluate the proper operation of the engine during maximum speed. When the engine is functioning correctly, it means that when you press the accelerator, the speed quickly increases to 15,000 rpm.

How to adjust the maximum number of revolutions

To limit this indicator, you need to use a screw marked H. To increase the number of revolutions, turn it clockwise, and to reduce them in the opposite direction. The maximum frequency should not exceed 15000 rpm.

If you make this figure larger, the device’s engine will wear out, which will lead to problems in the ignition system. When rotating this screw, you need to take into account the ignition processes of the device. If the slightest malfunctions appear, then the maximum speed value must be reduced.

Final check at idle

Before this procedure, it is necessary to carry out a full adjustment of the carburetor components when operating at maximum speed. Next, you should check the functioning of the device in idle cold mode. When the correct adjustment parameters are achieved, you will notice that the carburetor design closely matches the following criteria:

1. When the idle cold mode is activated, the chain does not move.

• When the accelerator is pressed even slightly, the engine accelerates at an accelerated pace. With gradual deepening of pressure, you can notice that the engine speed increases proportionately, reaching the maximum permissible values.
• When the engine is running, you can compare its sound to a four-stroke device.

If violations are noticed in the given parameters or the device has not been fully adjusted, you need to perform the main setup step again. Sometimes actions are performed incorrectly. In this case, the device may fail due to the loss of the correct node settings. In this case, you will have to contact a specialist.

Disassembling the carburetor if necessary to check or repair components

The design of different carburetor models is almost the same, so when working with them you can use the standard scheme. All elements must be removed carefully and then laid out in the order given below so that you can successfully place the items in place after the completion of the repair work.

1. The top cover is removed. To do this, you need to unscrew the 3 bolts holding it in a circle.
2. The foam rubber is also removed, since it is the upper component of the filter that conducts air.
3. The fuel hose is removed.
4. The drive thrust is output directly to it.
5. The cable end is disconnected.
6. The gasoline hose can be completely removed if you systematically pull it off the fitting.

To finally prepare the carburetor for major repairs or replacement of the smallest parts, you need to carefully disconnect it from the main system. Sometimes further disassembly is required. You should unscrew the components carefully and put the fasteners in groups, as these small parts are easily lost.

How does a carburetor work on a Husqvarna 137 chainsaw?

Chainsaws of these models are most often equipped with a Walbro carburetor from the factory. Before adjusting the Walbro carburetor on a Husqvarna chainsaw, you need to have a minimal understanding of its structure and know the principle of operation.

What is responsible for supplying the mixture of fuel and oil

For precise supply of fuel and oil, the operation of a fuel pump is used, which is driven mechanically from the crankshaft. The carburetor itself is equipped with a diaphragm and a special needle valve, which are responsible for regulating the pressure in the system. Thanks to them, the correct operation of the dosing chambers and the pump is organized, which improves the operation of the chainsaw.

Preparing the fuel mixture

When operating a chainsaw, a fuel mixture of gasoline and oil should be used in a ratio of 15:1 by volume, i.e., 1 liter of oil should be added to 15 liters of gasoline and the mixture should be mixed thoroughly. The amount of gasoline and oil in the fuel mixture is given in this table:

What is responsible for the air supply?

Two dampers installed on the diffuser chamber are responsible for the air supply. The first can regulate the amount of air at the moment you press the accelerator and is called the throttle, and the second ensures that the air supply is limited at the moment when the chainsaw is cold started. To make starting easier, the throttle is closed, which means the mixture becomes rich, as it is saturated with a large amount of fuel. It is easier to work in this mode, but since it increases fuel consumption, this mode is not used throughout the entire operation. The saw is working hard.

To spray fuel into the cylinders, an injector with a check valve is used.

The principle of operation is simple: it limits the return of the mixture back into the chamber. All the main malfunctions of chainsaws most often occur when this mechanism does not work properly.

1. The most common mistake is storing the tool for too long. The fact is that with prolonged inactivity, the valve sticks and either fills the cylinder with fuel, or simply does not open.
2. The second problem is an increase in the amount of air in the mixture, caused by its suction from the outside due to improper operation of the valve. It is no longer possible to adjust here, since in this case only repairing the valve or replacing it helps, since the saw will not respond to the adjusting screws.

Unlike a car, setting up a chainsaw carburetor provides three adjusting screws that are responsible for the quality of the mixture, quantity and nominal crankshaft speed of the Husqvarna engine:

• screw L – designed to adjust the number of revolutions when operating in medium modes and regulates low speeds;
• Screw H – adjusts the number of high speeds and thrust of the installation;
• T – is designed to adjust the total amount of fuel and adjusts the operation of the throttle assembly.

It is not recommended to touch the first two screws without special skills. The problem is that if you configure them incorrectly, the carburetor will not be able to start the engine, or even start it in the wrong operating modes. Such adjustment of the screw can lead to its rapid wear and failure. This principle is embedded in many devices.

No table provides the settings parameters. Therefore, you should not look for this data in specialized literature, but just strictly follow the instructions. The table in the passport has only informational value regarding the characteristics of the engine.

Device, tool maintenance instructions

Design of the Husqvarna 137 chainsaw: the simple design of the chainsaw consists of a block with a two-stroke engine, an air cleaner, a clutch, a fuel and oil reservoir and a guide bar with a cutting chain. Both the chain and the tire are replaceable equipment, completely replaceable with analogues after final wear (installation of components 15 and 13 inches long is allowed).

Fuel and oil, lubricants for husqvarna 137

The Husqvarna chainsaw engine is designed to run on unleaded gasoline. The best choice for this model is AI-95 or AI-92 gasoline. The ratio of gasoline to oil is 40:1, resulting in a 2.5% mixture for the operator. The fuel is mixed separately, in a special clean mixing container.

Oil recommended for Husqvarna chainsaw engine: manufacturer’s recommendation oil for two-stroke air-cooled Partner engines or original Husqvarna. Also use specific oil from Husqvarna or Partner to lubricate the bar and chain.

Oil for two-stroke engines PARTNER Oil Husqvarna HP 2-stroke

Duration of operation of the Husqvarna 137 chainsaw

The average operating time of a Husqvarna chainsaw on one refill is 30-40 minutes, depending on the degree of load. After running out of fuel, if you need to continue working, turn off the engine, let it cool and refuel the tool.

The agony of choice

Chainsaws were once the exclusive tool of farmers and loggers. Today, homeowners increasingly use them for collecting firewood, pruning trees, and building fences. The rise in popularity of saws has led to an increase in the number of models. As a result, purchasing a new chainsaw can seem a bit daunting.

When choosing, consider the following factors:

• Size is the main factor to consider when choosing a chainsaw. Generally speaking, larger chainsaws are more powerful, which is why they are required for heavy cutting tasks. The power of a chainsaw is measured by displacement (cc) and engine power (kW).
• Personal experience. If you are new to using a chainsaw, choose a smaller saw that is easy to operate and maneuver. A heavy chainsaw will quickly tire your shoulders and arms, reducing productivity and putting you at risk of injury.
• Size and type of wood to cut. If you are cutting down trees or cutting trunks to length, choose a larger chainsaw with more power. Using a small model will result in unnecessary physical stress and may simply kill the instrument.
• Guide Bar Length The appropriate guide bar length is determined by the maximum thickness of the trunk that needs to be cut and, to some extent, your skill level. If you often use a chainsaw, it is advisable to have two different sizes of bars, which will allow you to select the length depending on the size of the tree. A saw with a shorter guide bar weighs less and is easier to maneuver when removing tree branches. A longer bar is needed for felling and sawing large trees.
• Suitable type of chainsaw: Husqvarna offers several types of chainsaws, each designed with a specific user in mind:
• Amateur/non-professional chainsaws are compact, easy to use and more suitable for indoor work.
• Farm/semi-professional chainsaws are built for performance and durability. Preferred by homestead and farm owners, these saws are designed for occasional use when clearing undergrowth and cutting firewood.
• Sawmill/professional chainsaws provide maximum productivity and optimal ergonomics for foresters and loggers. These models are intended for permanent use. Some models are available with special features such as heated grips or AutoTune.
• Tree maintenance chainsaws are designed for landscapers and tree care professionals.

Husqvarna offers many models, but how do you know which saw is right for you? Fortunately, Husqvarna has prepared a summary table of the popular 27 chainsaws, thanks to which we can make the choice easier.

The various uses of a chainsaw are listed in the header of the table. The target audience and models of Husqvarna chainsaws are indicated on the left. Using the points, find the optimal type and model of chainsaw for your needs. Below we provide a brief description of each model and indicate their technical characteristics.

Saw set

The basic set of the removable saw device includes a 40 cm long guide bar made of a special alloy and a wear-resistant saw chain. The capabilities of the model 340 chainsaw are expanded by the ability to operate the tool with guide bars 35, 38 and 45 cm long.

Thanks to the reliability and high efficiency of the combined, manual and inertia emergency stop brake of the sawing mechanism, the prerequisites for the formation of traumatic situations are eliminated.

Full lubrication and cooling of the headset is achieved by supplying chain oil to the working area. This task is accomplished by a pump with adjustable performance, which takes consumables from a 250 ml reservoir built into the body.

The automatic system blocks the supply of lubricant to the tire when the engine is idling, which reduces oil consumption by almost half.

Price

Unfortunately, the Husqvarna model 340 chainsaw has been discontinued, so offers for the sale of new tools are extremely rare. The last recorded price of this model is within 14,500 rubles.

The branded assortment includes models that are similar in cost and performance parameters, but have increased versatility and improved performance characteristics.

In particular, modern technologies are used for applying wear-resistant protective coatings to the cylinder bore and loaded parts of the crank mechanism.
