Husqvarna 140 chainsaw review. Description, technical specifications and user reviews

The Husqvarna 140 chainsaw is a product of the world-famous Swedish company Husqvarna, which began its activities back in 1689. Initially, the company produced weapons for its soldiers, but since 1970, the range has changed; construction and gardening equipment and tools began to roll off the assembly lines of factories.

Technical characteristics of the Husqvarna 140 chainsaw

Another advantage of this household amateur model is its good factory parameters.
These include:

• petrol engine power – 2.17 liters. s./1.6 kW;
• engine cylinder volume – 40.9 cm3;
• crankshaft rotation speed at idle/maximum speed – 2700/9000 rpm;
• fuel/oil tank – 370/250 ml;
• oil pump speed – 13 ml/min;
• permissible length of the bar for comfortable cutting is 30–40 cm;
• chain rotation speed on the bar at maximum speed – 22.9 m/s;
• ready-to-use weight: 5.2 kg.

A distinctive feature of the Husqvarna 140 chainsaw can be considered the low noise level during its operation. During operation of the model under maximum loads, this figure is 112–114 dB.

Saw set

The removable cutting equipment kit includes a proprietary 360 mm long bar and a wear-resistant saw chain model H37 with a standard pitch of 3/8 inches. The power and torque reserve of the engine allows operation of the saw with a more productive bar 40 cm long.

Oil supply to the working area for lubrication and cooling of the headset is provided by a standard pump with a fixed capacity of 13 ml/min. Consumables are taken from an oil reservoir with a capacity of 200 ml.

Injury situations are prevented by the quick operation of the chain locking mechanism. The inertial emergency stop brake is triggered by a reverse impact when the headset fails to enter the cut or the safety shield moves slightly forward.

Pros and cons of Calm

Stihl chainsaws are considered one of the most reliable and for this reason are very popular among professional lumberjacks who are accustomed to working with powerful and reliable chainsaws. But if you look at the sales statistics for Shtil household chainsaws, you can conclude that they, too, are particularly popular. For example, the Shtil MS 180 chainsaw, from the moment it went on sale, annually occupies top positions in the ratings of such Internet portals as Yandex Market.

The advantages of Shtil 180 include:

• Light weight, 3.9 kg;
• Power sufficient to carry out work in the garden and beyond;
• Maintainability and availability of the Shtil company, a large number of well-organized services;
• The quality of the materials from which the chainsaw bodies are made.

All these advantages can be attributed to any product of the German company, but there is also one main disadvantage.

Compared to competitors, Stihl chainsaws have a fairly high cost of both the tools themselves and the spare parts intended for their repair.

In turn, the high price of spare parts stimulates the emergence of a large number of low-quality spare parts intended to replace original ones and manufactured mainly in China. Installation of such spare parts is carried out in service centers that are not authorized to repair Stihl chainsaws, which entails a reduction in the service life of the tools and adversely affects the image of the manufacturer.

Recently, the Shtil company began to produce the most popular chainsaw model, the Shtil MS 180, at a factory located in China. As company representatives explain, this is due to large volumes of products and preferential conditions for production. Representatives also note that the transfer of production did not affect the quality of products in any way, for the reason that control of all stages of production remained at the same level.

Equipment

As standard, the Husqvarna 140 comes complete with a 16-inch bar, which has a chain slot width of 1.3 mm. Also included is a 3/8" pitch chain with a length of 56 links.

To assemble the chainsaw, as well as to provide access to the spark plug, the kit includes a universal key, with which you can also install the bar on the saw and adjust the chain tension.

To protect the operator during transportation, the chainsaw package includes a special protective cover, which will also protect the saw set from dirt.

You can become familiar with the basic requirements for the safe use of the tool, as well as the nuances associated with operating a chainsaw, by reading the operating instructions that come with the Husqvarna 140 chainsaw.

The design and principle of operation of the Husqvarna carburetor

To successfully configure the Husqvarna chainsaw carburetor, you need to know its structure and understand how it works. In fact, everything is not as complicated as it seems at first glance.

The saw carburetor has a built-in fuel pump, which is responsible for transporting the mixture of gasoline and oil, as well as a diaphragm, a needle valve with a rocker arm. Their joint work makes it possible to dose the fuel supply to the main chamber and two dampers.

One of the dampers is designed to regulate the flow of fuel into the cylinder when you press the gas, it is called the throttle, the second is responsible for limiting the flow of air from the air filter to facilitate starting a cold Husqvarna chainsaw. At the moment when the operator shuts off the air supply to the carburetor using the air damper, the fuel mixture becomes leaner and its supply to the cylinder increases, due to which the chainsaw starts much easier than when a cold start is carried out in normal mode.

The operation of the Husqvarna carburetor involves a valve-nozzle, which atomizes fuel and prevents air from entering the main chamber. Often problems with saw operation can be caused by defects in this particular element. For example, if the chainsaw is stored improperly, the valve may stick, the fuel supply will stop, which will make the engine impossible to operate. Also, malfunctions in the operation of the nozzle can cause air to leak into the main fuel chamber of the carburetor. In such cases, adjusting the position of the adjusting screws will not correct the situation; repair or replacement of the unit will be required.

Three adjusting screws installed in the carburetor body are responsible for adjusting the quality and quantity of the mixture, as well as the number of crankshaft revolutions in idle mode:

• screw (L) – regulates the amount of fuel in low and medium speed modes;
• (H) – responsible for traction at high speeds and their number;
• (T) - changes the position of the throttle valve, thereby regulating the amount of fuel mixture entering the cylinder and the operation of the tool engine in idle mode.

Rules for preparing the fuel mixture

If you wish, you can create the mixture in question with your own hands. It is recommended to do this before using the chainsaw directly. Storing the finished substance for more than 10 days leads to the formation of a chemical bond between the additives, which reduces the service life of the engine. Experts recommend that before storing the chainsaw for long-term storage, drain the fuel and use up the remaining fuel at idle speed.

Proportions should be selected in accordance with the recommendations of the manufacturer of the device itself. Depending on the model and its technical characteristics, the indicator can vary from 1:20 to 1:100 or more.

Chainsaw fuel mixture

When mixing active elements, it is strictly forbidden to use waste or oil that is not intended for operation of a two-stroke engine.

How is mixing done?

You also need to pay quite a lot of attention to the direct process of mixing the components used. As a rule, the fuel mixture is prepared in a volume that will be sufficient for 3-4 refills of the device used. The mixing procedure can only be carried out using measuring containers.

Among the features of the issue under consideration, the following points should be noted:

1. Some chainsaw manufacturers include measuring cups with marks for fuel and oil in the delivery package.
2. If you don’t have a special container, you can use a canister or dry bottle. It is convenient to dosage using a regular syringe without a needle.

After adding all the ingredients into one container, you can begin directly mixing the components. To do this, the container is closed with a lid and then shaken to obtain a homogeneous substance.

Working proportions of the fuel mixture

As previously noted, the proportions of oil and gasoline for a chainsaw can differ significantly, largely depending on the features of the design itself. An example of mixing is the proportions 40:1 and 50:1. This ratio ensures high-quality lubrication of the internal elements of the installed engine.

In some cases, the lubricant concentration can be adjusted upward, resulting in more effective lubrication. An example is the case when a new tool is being processed. In addition, the cooling efficiency of the structure can also be increased by adding a large amount of oil to the mixture. Experts recommend increasing the oil concentration by no more than 20% of the usual value.

As practice shows, in most cases the sawyer himself has to adjust the concentration of oil in the fuel depending on the characteristics of the work being carried out. This is due to the fact that as the structure wears out, serious damage can occur. With normal operating characteristics, sawing can be carried out over a long period.

Measuring containers

Various containers with marked markings can be used as a measuring container. Controlling the ratio is simplified when using a proprietary container, which is included in the package.

It is worth considering that measuring utensils are included in the factory kit even for budget models. However, a regular syringe with increased capacity also performs well.

Storage recommendations

It is not recommended to save time and mix the composition directly in the chainsaw tank. This is due to the fact that achieving the required result will be quite difficult. Storage recommendations are as follows:

1. The resulting mixture can be stored for no more than 2 weeks. As the ambient temperature increases, the shelf life decreases to 10 days.
2. In some cases, in order to save money, a previously prepared and expired mixture is added to a new one. However, its concentration should be no more than 10%.

Storing homemade mixture

To prolong the operation of the fuel system, it is recommended to filter the composition through a material represented by fibers.

Chainsaw Husqvarna 135

The Husqvarna 135 chainsaw is a relatively new modification, developed by engineers of the Swedish brand Husqvarna, but produced at an American plant.

Chainsaw Husqvarna 135

Husqvarna once specialized in the production of weapons (since its founding in 1689), but since 1970 it has dramatically changed its specialization and has proven itself as a reliable manufacturer of gardening, construction equipment and power tools. The direction was chosen successfully, in a few years the international market was conquered, representative offices and factories of the company were opened on different continents.

Why is the Husqvarna chainsaw considered the best model?

There are no perfect tools, and every manufacturer strives for perfection. In the chainsaw market, Husqvarna, Shtil, Partner and Makita compete in the same class. This is high quality equipment. The choice is large, you should know the features of the brand so as not to make a mistake.

The entire range of Husqvarna chainsaws are characterized by improvements that make work easier and more comfortable. First, these new products are installed on professional equipment, then they are added to the layout of amateur models. These options include:

• X-Torq engine, which reduces emissions and saves fuel, increasing torque;
• automatic adjustment of the carburetor to workloads by the Auto Tune system;
• centrifugal cleaning before air intake Air Injection ensures less frequent filter replacement;
• the vibration damping system for the handle is represented by dampers, Low Vib absorbers;
• use of a primer - an easy starting system;
• the chain tensioner is located on the side;
• use of a single key for frequently performed operations;
• In addition to automatic lubricant supply, the driven saw sprocket has a hole for additional injection.

This is not a complete list of improvements; there are additional changes in some models of Husqvarna chainsaws.

In order to exclude counterfeiting of a well-known brand, a list of countries in which the named models are produced has been published. If there is another country on the label, then it is a copy. Production facilities are located:

• in the USA - 132E, 142E;
• Russian brands, Khimki - 254ХР, 257, 262ХР, 262ХРН;
• in Brazil – 55, 61, 288ХР, 268, 272ХР:
• the remaining brands are produced at the main plant in Sweden.

Therefore, a Chinese-made saw is no longer a branded product, it is inexpensive, and repairs are specific.

The advantage of chainsaws is the presence of a sufficient number of service centers where you can purchase spare parts for Husqvarna chainsaws. At first glance, a complex device can be repaired at home

It is important to understand the mechanism and interaction of all nodes. After the warranty period, some operations can be carried out independently

It is necessary to adequately evaluate your skills and it is better to entrust the repair of a carburetor or piston system to specialists. Spare parts for the Husqvarna chainsaw can be ordered through the online store with delivery by courier or mail. Spare parts for each brand are supplied separately.

Chainsaw Husqvarna 240

The recently released household chainsaw Husqvarna 240 has already earned recognition from many users. This model of gasoline saw is perfect for a summer house or estate. Like all Husqvarna saws, this saw has an accelerated supply of gasoline and, accordingly, quick start of the engine. The air cleaning system extends engine life. It is also possible to adjust the chain tension from the side of the tool, and the built-in broken chain catcher protects the operator from damage. The developed anti-vibration device provides comfort during operation and prevents the mechanism parts from becoming loose or spinning due to vibrations, thereby increasing the service life of the chainsaw. The engine power of the Husqvarna 240 is 2 horsepower (hp). You can pour up to 0.4 liters into the tank. fuel.

How the mechanism works

Almost all tools, both foreign (Husqvarna, Makita, Shtil, Partner 350), and Chinese chainsaws, and domestic (Druzhba, Ural), are designed the same. Therefore, finding the reason why the device does not start and stalls will not be difficult.

There are four elements where problems may arise:

• The fuel for which the carburetor is responsible;
• Lubrication;
• The air that enters through the air filter;
• A spark, the quality of which depends on the ignition unit.

Let's start with the fact that all tools start up differently - hot and cold. Two commonly used mechanisms are responsible for this process.

Be sure to look at what is written in the user manual. It states that when turning it on, you need to make sure that the emergency stop brake is engaged. But starting a saw with a brake is much more difficult, so sometimes it’s better not to turn on the brake.

As you can find out from the instructions, inside the body there is a fuel tank and an engine, and outside there is a saw part (bar with chain), a handle and a starter.

First you need to figure out exactly how the tool won’t start. For example, the saw starts up, but immediately stalls, or loses power and cutting quality.

It is very important to consider the quality of the fuel. If the mixture is prepared incorrectly or has deteriorated over time, then even such reliable tools as the Ural or Husqvarna 145 will not work

The instructions must indicate the proportions and special oil specifically for your chainsaw.

Another common problem is that the user fills the candle during startup. It needs to be inspected; if it is completely dry, then fuel is not passing into the cylinder.

If you see black carbon deposits or a lot of fuel, then the carburetor may not be properly regulating the fuel supply.

If your saw tool starts, but immediately stalls, then the problem needs to be looked for in the carburetor jet or fuel filter. Perhaps they are clogged.

To check if the breather is damaged, you need to disconnect the fuel hose from the carburetor and see if the fuel mixture leaks out of it.

If the saw does not start when hot, then the problem may be in the muffler. Sometimes it gets clogged from the exhaust itself.

Quite often, saw breakdowns occur due to a small amount of chain lubricant. This happens when the channels are clogged or the oil line is leaking.

Also inspect the connections of the pipes with the oil pump fittings to see if they are leaking.

It is very bad when a breakdown occurs in the cylinder. When examining it, you may find unevenness or chips, and this may be the cause of the problem.

Features of the Husqvarna 140 chainsaw and safety precautions

Design and functional features of the Husqvarna 140 chainsaw:

• patented Swedish technology for the design of the X-Torq chainsaw engine, with the help of which the tool uses gasoline more economically and does not produce large amounts of harmful exhaust;
• Air Injection system, which purifies the air and prevents engine wear, as well as extends the intervals between filter cleaning;
• inserts on the handles that reduce the vibration effect;
• chain tensioner on the side of the chainsaw body;
• there are markings to guide the felling of wood;
• the engine cylinder cover is latched, there is access to a quick check of the condition of the spark plug;
• vibration damping system - LowVib;
• easy start system - Smart Start;
• The resistance of the starter cord is reduced by 40% compared to chainsaws from other manufacturers.

Internal combustion engine with unique X-Torq system

Rules for safe handling of the Husqvarna 140 chainsaw:

• use appropriate protective equipment when operating the saw;
• do not allow animals and children to work with a chainsaw;
• never cut with the edge of the chain, as this may cause injury due to strong kickback;
• work according to the product manual - do not overload the chainsaw engine, if long-term sawing is necessary, take technological breaks every 40 minutes or every hour.

Information component

Filled with useful information, the operating instructions contain information on preparing the tool for operation, routine maintenance, and troubleshooting on your own.

By following these recommendations, the owner of the tool can correctly adjust the carburetor and saw chain, and also use original spare parts to perform simple repairs.

The full operational capabilities of the Husqvarna 140 chainsaw can be confirmed by the results of preliminary tests and a large number of positive reviews from owners.

Comparison of HUSQVARNA 140 by characteristics

HUSQVARNA 140 is the most powerful saw in its class, next to it in the HUSQVARNA chainsaw line

comes 435, which is already classified as semi-professional. The previous chainsaw is the HUSQVARNA 135, which is much more common than the 140 model, this is primarily due to the price.

Many people want to have a high-quality chainsaw, but the cost of even household Husqvarna saws is steep. Therefore, as a rule, they buy the most affordable one, for a long time this was the HUSQVARNA 135 (at the end of 2022, the most affordable saw is the HUSQVARNA 236). Looking ahead, I will say that STHIL 180, with which HUSQVARNA saws are often compared, is popular for similar reasons, a more affordable price and constant production for 18 years.

Here is a table of comparative characteristics of the Husqvarna model range.

As you can see from the table, the differences in characteristics are minimal, but the price is different! How so what's the matter?

It’s all about those little things that make working with a saw more pleasant, convenient, and reliable.

The main mistake is that people compare characteristics, but do not pay attention to those little things. For example, the 435 Husqvarna has a larger saw tooth on the chain, reinforced clutch, hidden fuel tanks, a window with a fuel level, etc.

Does the difference of 3 thousand rubles, the presence of these advantages, pay for itself? - yes in most cases.

In addition, once you have worked with Husqvarna's technique, you begin to appreciate it more. It’s like a good car; a premium model and an outright “bucket” can have the same amount of horsepower and fuel tank capacity. But the difference is noticeable and it is hidden in convenience.

It should be understood that one minor blemish can be very annoying to work with, for example, a removable cover to clean the fuel filter. Many saws have this problem; simply cleaning the filter in the “fields”, firstly, it is impossible to open the lid without a screwdriver, and secondly, it can be quickly cleaned. Or an anti-vibration system, it may differ on different models, seemingly similar technical characteristics, but your hands get more tired. I hope the message is clear, cunning Swedes don’t take money for nothing, they take it for convenience.

The device of the Husqvarna 140 chainsaw

The Husqvarna 140 chainsaw is equipped with a reliable 2-stroke gasoline engine with a volume of 40.9 cm3. Thanks to the X-Torq function, the tool's engine consumes less fuel, showing high efficiency when working in all weather conditions.

The proprietary Air Injection forced air supply system is responsible for uninterrupted engine cooling. It increases the time intervals between air filter replacements and reduces wear on the main engine parts.

To dampen vibration, the Husqvarna 140 chainsaw is equipped with the LowVib system. It consists of several dampers that absorb a large percentage of vibration from the motor.

The working bodies are represented by a saw bar and a chain. To tension the chain, the manufacturer has provided a side sprocket. This allows you to quickly adjust the chain without using additional tools.

The parts and mechanisms of Husqvarna 140 are placed under a durable plastic case. The manufacturer has provided free access to the tanks, as well as consumable elements of the model. There are special latches installed on the cylinder cover, which make it possible to save time when replacing the spark plug and cleaning the cylinder.

For the safety of the feller, the Husqvarna 140 device includes a guard for the operator's right hand and an effective inertia brake. There is a separate lever to turn it on and off.

Model specifications

The Husqvarna 140 chainsaw has solid factory parameters. These include:

• power – 2 l. With.;
• maximum rotation speed – 12000 rpm;
• fuel tank capacity – 370 ml;
• oil tank capacity – 250 ml;
• recommended tire length – 35–40 cm;
• chain pitch – 3/8 “;
• ready-to-use weight: 4.9 kg.

The Husqvarna 140 model is distinguished by its small dimensions. Its length is 75, width – 21 and height – 28.5 cm. The noise level during operation of the tool is 114 dB.

Owner reviews

I bought a brand new Husqvarna last year. Does the job 100%. Even when cutting tough and dense wood, the drop in speed is not critical. I like the external design; it’s not a shame to appear in public with such a car. The disadvantages are the absence of a drain valve in the sealed cap of the gas tank, and a tight starter. It’s a long way to take it to the service center, after the warranty expires I’ll try to solve the problems myself. Artem

After an unsuccessful purchase of a cheap Chinese chainsaw, I decided to enter the European level. I ordered Shtil 180, they delivered a completely different model, which turned out to be partially dismantled. I made the right choice in favor of the Husqvarna 140 chainsaw. During three seasons of flawless operation, I replaced only one magneto under warranty. The headset has fully served its life. Now I use the tool complete with a bar and a Shtil saw chain. Practice has shown that this is the best option of all possible. Misha

Description

The Husqvarna 135 chainsaw is not intended for long-term loads, but is indispensable in a private home or country house. Its “filling” has been improved, thanks to which the tool itself is characterized by increased reliability and durability, and is in demand among owners of dachas and cottages. The two-stroke internal combustion engine is equipped with a unique X-Torq system, which ensures the most complete combustion of gases, which leads to a reduction (by 20%) in the consumption of the fuel mixture and a reduction in the content of harmful substances (up to 70%) in the exhaust gases.

Husqvarna chainsaw in action

The power of the power unit is small - 2.04 liters. pp., this is quite enough to carry out everyday tasks. To make it easier to start the Husqvarna 135 chainsaw at any temperature, the Smart Start system was built in; in addition, the manual starter is equipped with an inertial spring, which reduces the operator’s effort when jerking.

Reduced vibration levels were achieved by built-in pads and dampers. Chain oil is supplied to the headset via a pump and oil-conducting channels. The safety system is expressed by a braking system and protection for the operator’s hands. The manufacturer recommends using a 40 cm long guide for sawing work, but, if necessary, you can always use a 35 or 45 cm bar. Many chainsaw owners prefer the 140 model over the 135 model; it is slightly more powerful, although the weight remains the same.

Advantages of the Husqvarna 135 chainsaw:

• Light weight (4.4 kg without cutting set).
• Small sizes.
• Tires of different lengths are used, in the Prior the size is 40 cm.
• Maintainability.
• X-Torq system.
• Start with Smart Start system.
• Inertial double cleaning with Air Injection.
• Carburetor Zama EL 41.
• “Low Vib” vibration damping system.
• Effective braking system.
• You can do the repairs yourself.

X-Torq technology

A distinctive feature of the Husqvarna 140 is that the saw is equipped with an internal combustion engine with a unique x-torq system. This system is designed to reduce the amount of harmful substances in exhaust gases.

X-torq is a patented development of Husqvarna. The system works on the following principle: fuel is supplied to the combustion chamber under pressure and mixed evenly with atmospheric air, which at this moment is supplied to the combustion chamber through special technological channels. After the engine power stroke occurs, the combustion chamber is filled with air and it is cleaned of unburned fuel, this also has a positive effect on the quality of the exhaust gases.

1. According to the manufacturer, engines equipped with the X-torq system have the following advantages:
2. Reduced emissions of harmful substances in exhaust gases. In an engine with this technology, the amount of harmful impurities in exhaust gases is reduced by 70 percent. This allows a chainsaw equipped with an engine with X-torq technology to meet even the most demanding international standards;
3. Economical. The manufacturer claims that a properly adjusted chainsaw with this technology requires 20 percent less fuel;
4. An engine with combustion chamber purging technology is capable of producing more torque at both medium and maximum speeds, which has a positive effect on its performance.

To get acquainted with the principle of operation of an engine with the X-torq system, you can watch a video taken from the official website of the Husqvarna company.

Adjustment work

The standard factory setting of the fuel system is made using averaged data, which during use is adjusted by the user taking into account external factors.

The chainsaw carburetor is adjusted in a sequence specified in the instructions, after cleaning the air intake filter and warming up the engine. By changing the characteristics of the air-gasoline emulsion, the engine is brought to an operating mode that is optimal in terms of power and efficiency.

The main signs of correct configuration:

• good throttle response and traction characteristics;
• stability of operating and idle modes;
• economical fuel consumption;
• no detonation noise.

The reason for a negative result may be air leaks, the presence of water in the carburetor, or clogged jets.

Analogs

Only the developments of leading manufacturers of innovative chainsaw equipment can compete with Husqvarna brand products. In the Russian household appliances market, demand has stabilized for models of the same type in terms of power, price range and purpose - STIHL MS 180-14, Oleo-Mac GS 35C-14 and Partner P842.
