Husqvarna 240: chainsaw review, technical specifications, repair

The Husqvarna 240 chainsaw is produced by one of the world's most popular manufacturers with more than three hundred years of history - the production and trading company Husqvarna (Sweden). The company was founded in 1689, at that time the brand produced weapons for the Swedish army, which it did for more than 280 years. Since 1970, the following products began to roll off the plant assembly line:

garden equipment;
garden tools;
construction equipment and tools.

Thanks to such changes, the company quickly gained popularity in the international market and firmly established itself there. Now the Husqvarna trademark is the owner of several well-known brands.

General information about chainsaws

Husqvarna is a well-known brand for those who professionally work with chainsaws, as well as for summer residents and gardeners. There are not many companies around the world that offer equipment of similar quality. Perhaps, only the manufacturer Shtill can compete with this brand. One way or another, the 240 modification is fully consistent with the best ideas about Husqvarna products that have developed over decades. The chainsaw continues the concept of the small household saw 236, but with significant modifications. Firstly, thanks to X-Torq technology, the designers have significantly increased the power potential of the unit. Secondly, changes were made to the optional software, due to which the Husqvarna chainsaw in the new version has become more convenient and safer.

What tasks can this device perform? For the most part, this is work within the framework of a private household - collecting firewood, pruning bushes and trees, clearing a site, etc. But if ordinary models for domestic use perform similar work in small volumes, then the 240 version differs from them in productivity and endurance. That is, for full maintenance of a country household, this chainsaw is optimal.

Saw set

The powerful carburetor drive takes advantage of the 52 cm long performance tire.

The design of the model 5200 saw and its prototypes uses a standard scheme for supplying chain oil to the cut. The consumable material is supplied to the pump inlet with a fixed capacity from a separate tank with a volume of 320 ml.
The response speed of the emergency stop brake ensures the safety of sawing operations in the event of traumatic moments arising from kickback or breakage of the saw chain. The Chinese saw is compatible with saw sets from other brands.

The instruction manual included in the supplied kit provides a small amount of information on preparing the tool for operation and maintenance features.

Using her recommendations, the owner can adjust the carburetor, tension the chain, or perform simple DIY repairs at home.

Husqvarna-365

And, of course, it has completely different characteristics. With a power of 3.4 kW, it is capable of carrying a saw bar up to 70 cm long, which speaks for itself.

And even a weight of 6 kg does not seem excessive. The same cannot be said about the price of 36 thousand.

You may need such a saw in your household only if, in addition to sawing trunks into logs, you are also engaged in felling these trunks, which is quite doubtful.

A complete list of components and working parts of the chainsaw is specified in the operating instructions. The production and assembly of this model were carried out by Svensk Maskinprovning AB (Sweden). The saw complies with EU requirements for household appliances in terms of noise level and technical indicators.

Cost of Husqvarna 240 chainsaw

The cost of the new model in Russia is from 11,990 rubles, depending on the store that sells the product. In Ukraine, such a saw can be bought at a price from 5,600 to 8,000 hryvnia; in the USA, the Husqvarna 240 model currently costs from 180 usd.

General characteristics of Huskvara chainsaws

Of course, this manufacturer, known for over 300 years, has its own identity. In Husqvarna chainsaws it has a pleasant bright orange color.

By the way, deviations in color, as well as excessive glossiness or dullness of the covering may indicate a fake. Just like the rich black color of the handles and shield, the original products are rather dark gray. And the sheer number of fakes is further evidence of the brand’s popularity.

All brands of these saws have a digital marking of 3 or 4 digits, in which the first is the serial number of the generation of the saw, and the two following it are the rounded volume of a two-stroke gasoline engine. Also, letters can appear after numbers:

e – indicates the presence of the SmartStart easy start function;
XP – indicates the presence of an AirInjection air pre-cleaning system;
G – have heated handles and carburetor.

There are also notations:

more economical engine - X-Torq;
increased ability to work in bad weather conditions and on low-quality fuel - AutoTune are professional saws;
improved vibration protection - Low Vib.

Weaknesses of Husqvarna chainsaws

Despite the fact that more than 80% of all user reviews of Husqvarna chainsaws are definitely positive, we have selected some problems that are typical for generations 1 and 2, most often used by Russians in the household.

In the first place is the problem of slight oil leakage from the chain lubrication system; sometimes this happens even on idle saws.

The second common unpleasant feature characteristic of Husqvarna is what the owners call a starter that is much stiffer than that of other chainsaws. This becomes especially noticeable if the saw has a habit of not starting the first or second time, which happens in some cases if the owner did not check this function upon purchase. This most often occurs due to poor-quality factory settings of the carburetor, which is the problem with quite a few household Husqvarnas.

Absolutely all users who left unflattering reviews about these saws note the disgusting translation into Russian of the instructions for the chainsaw. In addition to the fact that it is written in an incomprehensible language and in many cases requires further thought and semantic correction, it sometimes contains obvious inaccuracies.

Sometimes complaints are also caused by Husqvarn chains, which require frequent tightening at the initial stage of operation until they stretch.

Some models sometimes stall when turning 90° when cutting down trees.

But the biggest complaints are caused by the prices of branded oil, the replacement of which with cheaper brands causes refusal of warranty service and repairs.

Positive aspects of a chainsaw

It must be said that there are not so many similar reviews about Husqvarna chainsaws and they are clearly offset by the overall positive impression of their work. Everyone notes:

excellent balance of instruments;
low vibration and low noise during operation;
sufficient power reserve to perform the functions provided for each specific model.

If a thick oak log is being sawed with a lopper, then the power may not be enough.

Of the listed models, only the semi-professional 365 can cope with such work, but even after 40 - 50 minutes of work it needs to be given a rest.

When choosing a specific Husqvarna model, determine for what purpose you need it, and only then compare its price with your capabilities. A properly selected saw can easily last 5 years or more with fairly intense use, which saws from lesser-known brands are unlikely to boast of.

Husqvarna 240 chainsaw malfunctions

The main causes of breakdowns of the popular model of the Swedish brand, as a rule, are improper operation or wear and tear of the main parts of the operating saw mechanisms. Most of the malfunctions of garden tools can be fixed independently, which can save a significant amount and time of the owner.

Why gasoline leaks - causes and troubleshooting

Arbitrary leakage of gasoline becomes a common cause of breakdown of the fuel tank or malfunction of the pump responsible for pumping fuel through the fuel pipes. If the cause of the breakdown lies in the pump, then it will need to be replaced, since the pump cannot be repaired.

You can fix a breakdown in the fuel tank yourself. If the hole is not large, then it can be treated with sealant. If the hole in the tank is too large, then the entire plastic tank will need to be replaced.

Advantages of the Husqvarna 240 chainsaw

The model is equipped with an engine of the new X-TORQ technology. X. Therefore, the Husqvarna 240 is characterized by increased environmental friendliness due to reduced exhaust emissions. Also, the design of the engine allows for economical use of fuel, reducing its consumption.
The built-in Air Injection air purification system reduces wear on tool filters.
The vibration reduction system reduces the negative effects on the human body. The manufacturer moved the engine further away from where the handles were attached and installed mufflers.
Convenient chain tension adjustment is located on the side of the tool.
The inertia brake ensures safe use of the Husqvarna 240.

Among the disadvantages of the model, users note high oil consumption due to the mechanical pump. Also, the air filter should be made of more durable material.

To reduce fuel consumption, we recommend diluting the oil in a ratio of 1:50.

Features of the Husqvarna 240 chainsaw

The Husqvarna 240 chainsaw is a semi-professional tool. Well suited for sawing boards in the private sector or cutting branches in the garden.

The production and assembly of the car takes place in the USA. The tool comes with a two-year warranty.

Husqvarna 240 chainsaws have decent technical indicators:

General characteristics of chainsaws

Chainsaw. This is a portable, indispensable tool for cutting and sawing wood in private households.

Household machines are designed to operate 1 – 3 hours per day or 50 hours per month. Their design is simple and characterized by low weight and low power. A good choice for occasional work.

Professional models can withstand heavy loads and 8 hours of continuous operation. Their power starts from 2.5 kW and 9 thousand / min. chain revolutions. Used in forestry and industrial production.

The intermediate link is semi-professional chainsaws. They are a reliable assistant both in repairing and felling trees. A universal choice for systematic use. The saws have good power, but are designed to work 3 – 4 hours a day.

When choosing a chainsaw, you need to decide on the tasks it will perform. And choose the model required in terms of power. Then she will serve on the farm for many years.

Husqvarna 137

This is a household saw with a power of 1.64 kW, which can cope with most household tasks.

Chainsaws 137 were equipped with tires from 33 to 38 cm in length and, weighing just over 4.5 kg, delighted owners with their performance and ease of use.

This model has not been produced for several years, so if you are offered a new Husqvarna-137 in any store, you can be sure that they are offering you a fake. This saw of original production can only be purchased in an online store that sells used tools or second-hand. Its cost at the time of termination of sales was around 6.5 thousand rubles. and for most users it honestly earned every penny.

Break-in (break-in) of the Husqvarna 240 chainsaw lasts at least 10 hours. This time is quite enough for all the moving parts of the tool to get used to each other under gentle conditions of reduced loads.

Maintenance

Maintenance of the Husqvarna 240 chainsaw comes down to the following:

Cleaning petrol tools from sawdust, oil and petrol stains and other contaminants
Work on cleaning or replacing the spark plug and drive sprocket.
Replacing or sharpening the chain.
Idle speed adjustment.
Brake system repair.

Basic problems and solutions

The chainsaw does not start at all, possible reasons:

fuel tank is empty;
water got into the fuel;
fuel quality is low;
the startup procedure was not followed;
the carburetor is out of adjustment or dirty;
The air filter has not been cleaned;
fuel lines are clogged;
the piston group is worn out, the rings are worn out, there is no compression;
piston jammed;
no spark;
the ignition does not work;
high-voltage cable break;
problems with spark plugs.

The power plant is running, the chain does not rotate:

the chain is overtightened;
the chain has become loose.

The saw set is heating up, no oil is flowing:

clogged channels through which lubricant is supplied;
empty oil tank.

The Husqvarna 240 chainsaw stalls when the load increases, reasons:

the carburetor is out of order;
The ignition system is not working properly;
The filter needs to be cleaned or replaced;
The spark plug does not respond (it is wet, smoked or burned out).

How to adjust correctly

For this purpose, the design of the device provides 3 adjusting jets. The idle air adjustment screw (T) is located at the top of the carburetor. Below there is a pair of jets for adjusting the fuel supply at minimum (L) and maximum (H) speeds, left and right, respectively.

The procedure for adjusting the carburetor on a Husqvarna chainsaw is as follows:

Warm up for 5 minutes.
By turning screw L, we bring the engine to the highest speed in an unloaded state and return it back a quarter turn.
Hold the gas button with one hand for 15 seconds. At this time, turn the jet H to the right until it stops and reaches maximum speed. Then we turn it back one and a half turns or until the “squealing” of the engine disappears.
After releasing the gas, turn the idle speed screw (T) clockwise until the chain begins to move. After this, we rotate it in the opposite direction until the chain stops moving.

During the adjustment process, a situation may arise in which the chainsaw stalls. This could be due to the jets being too tight or the mixture being too rich or too lean.

If this happens, you need to tighten the minimum and maximum speed jets all the way. Then turn them back one and a half turns and try to start the saw.

Setting the ignition after adjusting the carburetor

If cleaning and adjusting the carburetor does not correct the existing problem, you need to check the spark plug and adjust the engine. You should act in the following order:

The spark plug is unscrewed and a visual inspection is carried out. If it is dry with a slight brown soot, it can be considered in good condition.
If traces of gasoline are found on the spark plug, the carburetor should be re-adjusted. This happens because it supplies excess fuel to the internal combustion engine, flooding it.
If the spark plug looks normal, check the operation of the electrical equipment. First of all, the cable that supplies current to the spark plug. Its end is brought a short distance to the radiator grille of the cylinder and the starter is turned with a cord. There should be a spark. If it is not there, the cable is checked with a tester and replaced if necessary.
If the cable is in good condition, test the ignition coil. If the inspection does not reveal singed or broken wires, the coil is run through a tester, comparing the data with the accompanying documentation. If deviations are detected, the block must be replaced with a similar one.

After replacing the coil unit, the gap in the magneto should be adjusted. The gap between the ignition coil and the flywheel should be from 0.2 to 0.4 mm. To set the gap, you need a set of feeler gauges or you can use foil of a suitable thickness. The probe is clamped between the coil and the flywheel at the time of installation, and then pulled out.

Repair of Husqvarna saws

Let’s make a reservation right away: this equipment, despite not having a very large number of parts, is high-tech, and spare parts for it are very expensive, so it is advisable to carry out any repairs at a Husqvarna service center. Simply, independent intervention can not only void your warranty, but also lead to disastrous results.

Although there are a few areas you can tamper with without fear of harming your chainsaw.

1. Carburetor adjustment. We will look at it using the 137th model as an example.

For this:

screw L to set the highest speed;
after warming up the engine for 15 - 20 seconds. use screw H to set the quality of the mixture (if it smokes, it’s rich and tighten the screw, and if it squeals, it’s lean, unscrew it);
Use screw T to adjust the idle speed, rotating it clockwise until the chain begins to move, then slowly unscrew it until the chain stops completely.

2. Ignition . There is nothing to install in it; its repair (except for physical damage to the flywheel) comes down to replacing the coil (aka magneto). Here you need to choose a spare part with the same markings as on your saw, even if it fits the seat. The ignition timing may not match.

3. Clutch repair. There is an unspoken rule: after replacing 2 saw chains, the tire should be replaced, and after replacing 2 tires, the clutch should be replaced. Of course, this is not a dogma, and in each individual case it is worth checking the functionality of the unit before changing it, but you can carry out the procedure for replacing the clutch (as well as the chain or tire) yourself.

It's easy to do:

remove the tire;
fix the piston through the spark plug hole;
unscrew the clutch;
install the new one by performing the steps in reverse order.

Modifications

Husqvarna tries to supplement each successful model with versions provided with some improvements. Since users have conflicting opinions regarding one or another characteristic, sometimes several modifications are born, intended for different consumer categories.

In the case of the Husqvarna 240, we can talk about the S and SG versions. The first is less popular and is an optimized option, designed specifically for small-format operations with low resource costs during operation. The SG modification received a redesigned power filling. It did not increase power or performance, but became more reliable and durable. That is, the cutting quality has remained the same, but the wear resistance of the element base has increased.

Adjusting the chainsaw carburetor

The carburetors of most chainsaws have three screws for adjustment:

L – jet screw for low speed adjustment
H – jet screw for high speed adjustment
Screw. T at Partner and Husqvarna (at Shtil LA) - adjusting the idle speed of the chainsaw

Screws H and L adjust the ratio of the mixture of gasoline and air, determined by the opening of the carburetor throttle valve. When the screws are unscrewed, the mixture becomes richer, and the speed increases accordingly; when the screws are tightened, the mixture becomes leaner - the speed drops.

The T(LA) screw is designed to adjust the idle speed. The basic adjustment of the chainsaw is made at the manufacturer during the final test. The carburetor is usually adjusted to supply a richer (than optimal) fuel mixture. The factory setting must be maintained for the first hours of operation of the saw. Then (optional) more precise adjustment of the carburetor is made.

We begin the adjustment by adjusting the idle speed; to do this, rotate the T screw (LA) counterclockwise, achieving a complete stop of the chain at stable engine speeds.

For further precise adjustment, you will need a tachometer and it is better to entrust it to specialists. especially since in most cases it may not be needed.

We start setting up the tool with screw L, then use screw H and finally screw T (LA).

We find the highest idle speed, to do this we slowly turn screw L in different directions. After finding the position of the highest engine speed, turn screw L 1/4 turn counterclockwise. Adjusting the carburetor of chainsaws 180, 230, 250. If the chain rotates at idle, screw T should be turned counterclockwise until it stops.

Screw H regulates power and speed. Adjusting the carburetor to a lean mixture leads to excessive speed, engine overheating and failure of the piston chainsaw.

Warm up the chainsaw engine at idle speed for at least 10 seconds and turn screw H 1/4 turn counterclockwise. Adjusting the carburetor of a chainsaw using an example. Let the engine run for about 10 seconds. then we check the maximum engine speed with a tachometer. How to tune the carburetor on a chainsaw Husqvarna Adjusting the carburetor on Husqvarna 240 in this video. If the maximum speed does not correspond to the nameplate speed, the operation should be repeated. When the mixture is supplied too rich, the muffler begins to smoke; when the mixture is too lean, the saw squeals and overheats.

We complete the adjustment by adjusting the idle speed, as already described above. The idle speed is set correctly if the engine runs smoothly at minimum speed and the chain does not rotate.

The carburetor can be considered adjusted if the engine accelerates quickly and sounds like a four-stroke at full throttle.

Preparing the chainsaw for work

Before putting into operation the tool must be properly prepared:

The chainsaw is assembled into a single structure.
The headset is mounted and the saw chain is tensioned.
The saw is fueled with oil and a pre-prepared fuel mixture.
The tool is launched. as described in the manual.
The functionality of the braking system is immediately checked.
Checking the supply of oil to the chain.
The idle speed is adjusted.

The saw is started, all systems are engaged and working - all that remains is to break in the chainsaw. And the video will tell you how to start the Husqvarna 240 chainsaw correctly.

Run-in

The break-in period lasts about 10 hours. During this period, gas-powered tools are operated in a gentle mode, without increased loads. The purpose of break-in is to grind in all moving parts of the chainsaw. If you skip the break-in and immediately put maximum loads on the chainsaw, the likelihood of the piston jamming increases sharply, which can lead to engine failure.

How to properly prepare the fuel mixture

To prepare a flammable mixture, the manufacturer recommends taking:

high-quality gasoline with an octane number of at least 90 and no more than 93;
original Husqvarna engine oil for two-stroke power plants.

The ratio of gasoline to original two-stroke oil is 50/1 (this is about 2%), in the case of using motor oils from other manufacturers (JASO FB/ISO EGB class oil is allowed) the ratio will be about 3% - 33/1.

It is recommended to use original chain oil of special viscosity as a chain lubricant.

Chainsaws "Husqvarna" - main malfunctions

A tool from a Swedish manufacturer can turn hard work into a simple task. The Husqvarna 137, Husqvarna 240 and Husqvarna 365 chainsaw models are distinguished by three features:

high engine power;
improved engine filtration system;
the ability to absorb excess vibrations.

If you operate the tool strictly according to the instructions and correct its problems in a timely manner, then it will delight you with reliable and stable operation. Correctly carried out repairs with original spare parts will allow you to use the saw for a long time.

The main cause of chainsaw failure is most often engine failure, which can manifest itself as follows:

won't start;
Unstable operation at idle speed;
starts and stalls immediately;
do not have enough power.

In this case, the fault should be looked for in the ignition system, piston group or fuel system. Often the reason for poor tool performance may be related to the clutch, brake system, lubrication mechanisms, or tire.

Ignition system

Do-it-yourself repair of the Husqvarna 240 chainsaw, or any other model, should begin with troubleshooting in the ignition system.

First of all, experts recommend removing and inspecting the candle. The condition of this element will indicate shortcomings in the operation of the fuel system.

If the spark plug is completely dry, it means that the fuel mixture is not entering the cylinder. In this case, the spark plug is screwed into place and the fuel system is repaired.
If the spark plug is heavily flooded with the fuel mixture, the rules for starting the unit may be violated, or the carburetor may be poorly adjusted. It is necessary to turn off the fuel supply and start the starter. This is done in order to remove excess fuel. The candle must first be cleaned with a sharp object, then washed with detergents, dried with a hairdryer and put back in place. After this, the tool is launched and its operation is checked.
If there are no fuel residues on the spark plug, then it must be cleaned, washed and checked for the presence of a spark. Its absence may indicate a violation of the gap between the flywheel and its magnetic circuit or a breakdown of the ignition module.

A malfunction in the ignition system may be due to the use of bad oil or an incorrect ratio of gasoline to oil.

Fuel supply system

If fuel does not enter the chainsaw tank, there may be two reasons for this:

The filter is clogged.
The lid is clogged.

In this case, the fuel is not supplied in full, and the tool does not start or starts and immediately stalls. The repair consists of cleaning the air filter and cover.

The filter must be removed very carefully so that the dirt that clogs it does not get into the carburetor. It can be cleaned and washed with ordinary detergents.

Carburetor repair

The heart of any chainsaw is the carburetor, which is responsible for most tool failures. Do-it-yourself repair of this unit involves disassembling and cleaning. If the breakdown is serious, then you should contact a service center for help.

Most often, tool malfunctions are associated with the use of low quality gasoline or oil. To protect the carburetor from damage, you must follow some preventive measures:

The chainsaw should be started strictly according to the instructions.
It is not recommended to store gasoline in a plastic container. This will help avoid severe soot.
The fuel mixture cannot be stored for a long time, as over time it loses its quality.

Husqvarna-236

This model replaced the much-loved 137.

Having slightly less power (1.4 kW), it added 100 g in weight, gained a 40-centimeter saw bar and, most importantly, a new engine, 20% more economical than its predecessor, with higher torque and a wider speed range, which did the job with this saw it is even more comfortable and has slightly expanded the range of its applications.

True, its cost has increased somewhat and today amounts to almost 11 thousand rubles, but if you recalculate to the current dollar exchange rate (and these saws are produced in Sweden and the USA), then everything will fall into place.

General information about chainsaws

The chainsaw continues the concept of the small household saw 236, but with significant modifications. Firstly, thanks to X-Torq technology, the designers have significantly increased the power potential of the unit. Secondly, changes were made to the optional software, due to which the new Husqvarna chainsaw became more convenient and safer.

Carburetor adjustment

Correct tuning of the fuel system contributes to the stability of engine traction characteristics and economical consumption of fuels and lubricants.

The need to adjust the carburetor most often arises when transferring the tool to seasonal use or using gasoline with a different octane number.

The work is carried out in a sequence specified in the instructions, after cleaning the air intake filter and warming the cylinder to operating temperature.

The main signs of correct carburetor adjustment:

engine response and speed stability in all modes;
absence of smoke and extraneous noise, including detonation noise.

If the engine simply does not start or starts and stalls, you should ensure the availability and quality of the fuel poured in and the serviceability of the spark plug.

The power unit stalls when the gas is pressed - the main cause of the malfunction may be a lean mixture due to a clogged main jet.

Features of use

Features of using the Husqvarna chainsaw:

carefully read the operating instructions for the chainsaw;
Perform switching on and off, idling, refueling and other technical procedures only according to the instructions;

Owner reviews

Valery, Otradnoe:

The file is gorgeous, I read the reviews and thought it would be a delight, but sometimes I come across negative opinions. Well, I’ll say that the unit is decent, and for those whose equipment breaks down, guys, don’t be offended, you need to read the instructions carefully, then repairs won’t be needed. Each company makes an instrument in its own way, Husqvarna has more than one feature, work, study, and everything will be great.

I’ve been using my 240th chainsaw for more than 4 years, I’m happy as an elephant! Super Swedish technology, what else do you need?
