The main types of malfunctions and methods for their diagnosis. If it is completely dry, then it must be installed in place, and look for the cause of the breakdown in another place.
If there are traces of fuel on the candle, then the malfunction is really somewhere nearby.
Wipe off the spark plug, turn off the fuel supply and turn on the starter. This will get rid of excess fuel in the combustion chamber. After that, install the spark plug in place, check the carburetor adjustment in accordance with the instructions, and carry out the start strictly following it.
Another problem is the presence of soot on the candle. Besides the fact that it needs to be cleaned, you also need to reconsider your approach to the oil used. Sludge appears due to poor quality oil, which not only complicates the operation of the ignition system, but also contributes to the root wear of other parts of the saw.
If cleaning the plug and purging the combustion chamber does not help, check the gap between the electrodes and the plug. You can correct it using a new gasket.
In cases where the spark is completely absent even when replacing the spark plug, it is advisable to contact a specialized workshop, since the problem can be caused by a malfunction of the high-voltage cable.
Fuel supply system.
First, check the carburetor adjustment.
If fuel still does not flow into the cylinder, remove the fuel hose and check the fuel supply. A weak jet indicates a problem in the fuel filter. It must be washed in water, dried and put back.
Similarly, check the air filter. Inadequate airflow into the carburetor can cause the engine to stall.
After flushing the filters, inspect the system for foreign particles that may interfere with the flow of fuel.
If all else fails, the cause of the malfunction may be in the carburetor itself, and this is already a complex device, and it’s better to turn to professionals.
When the saw dies with increasing speed, it is advisable to check the muffler. A spark arrestor is placed there, which is often clogged with various combustion products. To eliminate the malfunction, the muffler should be well cleaned.
The remaining breakdowns of the chainsaw, as a rule, are more serious and require qualified repair.

How to adjust yourself chainsaw carburetor? Customization carburetor chainsaw how to adjust the carburetor at a chainsaw benzyl supervisor how to adjust a carburetor?
A carburetor is one of the most significant elements of a chainsaw. The correct fuel mixture reduces fuel consumption and extends the repair-free life of the fuel.
When is carburetor adjustment required?
- Run-in of the engine has ended. The manufacturer exposes a richer mixture for the initial period of operation
- The engine starts, but immediately stalls (does not start at all). Perhaps there is little fuel in the mixture
- Large exhaust emissions, increased fuel consumption. On the contrary, there is a supersaturation of the mixture
- The positions of the carburetor screws are violated mechanically. Due to vibration, damage to parts of the body
The adjustment schemes of most saws are arranged on a similar principle. For example, take a Stihl chainsaw and analyze how to adjust chainsaw carburetor.
There are three screws marked with letters on the carburetor body:
- L. Controls the quality of the mixture at low at low speeds
- H. The same thing, only at high speeds
- T. Idling, clockwise increases, counter. Decreases
To adjust the saw you need to follow the instructions step by step:
- View manufacturer’s documentation and restore basic screw settings with a thin screwdriver
- Ensure the cleanliness of filters, muffler, as well as the quality of the fuel filled
- Start a chainsaw, let it warm up to operating temperature
- Turn screw L to set maximum idle speed. Then unscrew L one turn, in case of chain rotation. Unscrew screw T
- Use screw H to set the highest speed. To do this, wrap H until engine malfunctions, then slightly back (counterclockwise)
- Turn the screw T to achieve low idle speed. Unscrew it until the chain stops
- Check the carburetor for proper acceleration and maximum power. With a smooth pressure on the gas, the revs must gain confidence and quickly. Husqvarna 137 chainsaw device, technical specifications, carburetor adjustment, do-it-yourself piston and sprocket replacement on the Husqvarna 137. The sound of the adjusted saw should not be ringing. At maximum speeds it should be a little four
- Adjustment is completed if item 7 is completed and the saw stably keeps idling. Otherwise, we return to point 4 and repeat again.
The most accurate tuning can be done using the tachometer to determine the speed. When performing work, one should act thoughtfully, reasonably. This will help to avoid breakdowns and troubles.

The chainsaw is an irreplaceable assistant for every real owner.
Since its inception, its popularity has grown rapidly.
So, the Husqvarna 142 chainsaw has the highest functionality. It is widely used not only in forestry, but also in personal plots.
Choosing a chainsaw is quite simple. So, it is ideal to focus on well-known brands such as Husqvarna. This company produces a wide range of such tools. Husqvarna 240 and other models have the highest quality and functionality. But, unfortunately, even such tools are not safe from breakdowns.
After the chainsaw appeared in the house, many owners sighed with relief.
Indeed, this tool allows you to solve complex problems quite quickly and simply.
But, it is worth considering that a chainsaw often fails. This is due to the fact that it is subjected to huge loads during operation. Therefore, it is always necessary to be prepared to eliminate breakdowns.
Now there are a huge number of workshops that offer their services for the repair of chainsaws and other tools. But, this does not mean that when a malfunction occurs, you must immediately run to the repair shop.
Some faults can be removed with your own hands. To do this, you just need to know the main prerequisites for the occurrence of breakdowns and the method for their elimination.
So, in the process of frequent use of the tool, breakdowns may occur:
Each of these breakdowns can be fixed. Do it yourself. The main thing is to know the sequence of work when fixing a particular malfunction.
Read the article about self-repairing a Stihl 180 chainsaw here.
If the tool suddenly stopped working, then the first thing to check is the ignition system. And you need to start with a candle.
Work must be done very carefully. A special hook is used for this. First you need to disconnect the wire and remove the candle.
If it is dry, it means that no fuel is entering the cylinder.
Dismantling assembly of the HUSQVARNA 142 chainsaw
Why does not start chainsaw.Reason: How to fix it.
The chainsaw does not start or starts poorly. Cause and how to eliminate.
Common Huswarna problem 137 /142.
If there is spray on it, then the breakdown may lie in the carburetor or in the launch rule. To fix the breakdown, wipe the candle and shut off the fuel supply. After that, the starter starts.
Thus, the combustion chamber is ventilated and excess fuel is removed. After that, the candle is put in place and the chainsaw starts.
If there is soot on the candles, then this indicates that the Husqvarna 137 chainsaw runs on low-quality fuel. Also, carbon deposits are formed as a result of the wrong ratio of fuel and oil. In order for the tool to work as long as possible, you need to carefully study the operating instructions.
If there is soot on the candle, then it must be carefully removed. You can use an awl for this. The electrodes are gently rubbed with sandpaper. After that, it is installed in place. You also need to fill in the fuel, which is recommended to be used for this model of chainsaw.

Malfunctions in the fuel supply system
If the tool does not work, this may be due to the fact that no fuel enters the cylinder.
First of all, you need to check the fuel filter for contamination. To check this, remove the fuel hose and check how fast the fuel flows.
If it is supplied under low pressure, then the problem lies precisely in the filter.
In this case, clean the filter. It goes directly through the tank. The filter is cleaned and installed back. It is washed under a stream of clean water.
After that, the filter is dried and carefully installed back. In order to further prevent the occurrence of such a malfunction, it is necessary to periodically clean the filter.
If cleaning the filter does not give a positive result, then you should pay attention to the breather. Clogging of this hole causes insufficient air to flow into the carburetor.
Malfunction silencer and carburetor
Frequent use of the chainsaw may cause muffler malfunctions. Defining this is very simple.
If the tool works normally, and when the speed increases it starts to stall, then the cause is the spark arrester.
Most often, the breakdown of this element as a result of clogging with combustion waste. You can easily solve this problem with your own hands.
First of all, you need to remove the muffler and disassemble it. It is worth considering that in some models spark arresters are not understood. After that, the muffler is cleaned of soot. To do this, use special detergents.
When the carbon deposit is removed, the spark arrestor is dried with a hairdryer. At the final stage, the muffler is installed in place.
As for the carburetor, its adjustment and repair can be carried out at home. But in order to perform such work efficiently, it is necessary to know the structure of the carburetor and the principle of its repair.
Poor repair can cause serious damage to the device. Therefore, experts recommend that you configure and repair it in special workshops.
As you can see, it’s fashionable to fix many chainsaw malfunctions with your own hands. But to do this, you need to have certain information. If you are not confident in your abilities, then it is better to turn to specialists for help.

Faults Chainsaws Husqvarna 137. Nzizn.Ru
Failure Saws Husqvarna 137
Question: A standard discrepancy happened (Husqvarna 137 chainsaw (impulse channel seal). After the replacement, the saw appeared unknown malfunction.
Starts up well on Idling it works stably, but after 5 minutes of operation the power drops, saw starts to work at high speeds and to get a buzz. I suppose that the problem is in setting up the carburetor, but I don’t know what exactly to regulate.
You don’t need to regulate it yourself, for this you need a pressure gauge, if you lean the mixture, then throw out the piston. See the carburetor mount, when the saw is heated, somewhere it starts to suck in air.
He removed the carburetor, disassembled, washed, blew. 0 results.
I disassembled the saw and completely found out that the rubber tube that connects the carburetor and the sleeve (small) was worn, the group is normal, the clearance in the ring too, there is play in the bearings (more noticeable from the ignition side since 1 lobe has been broken off on the flywheel, I think it’s also a play) collected, start only on the suction, it works for 3-5 seconds and stalls.
Opening the damper, it melts immediately, after several attempts, the candle and piston become wet. What could be the reason? Maybe air leaks from under the oil seals? Overfills the carburetor?
I hope the phone was replaced. There was a disassembly of the carburetor, did the idle screws and mixture quality turn out? If the oil seals suck, there will be a depletion of the mixture, and in theory the candle should not be filled. The fact that the petal on the impeller is broken is extremely bad. The imbalance at 11,000 rpm will be terrible, the bearing will decently decouple.

Husqvarna 137 chainsaw won’t start
Common husvarna problem 137/ 142.
Rearranged the ignition coil from the 142nd saw. The result. It starts, but before starting up, you need to swing the trigger many times. And if it starts up that the engine works, only if you pull the trigger. That is, it is intermittent. At full throttle does not work, at Idling. Also. What else to check?
I pulled out this device where the pump tip is inserted, blew it, and no results. I cleaned the plastic tube with a wire where it happens, I think so that the air gets into the tank, and no results. What to do?
And the gear should go freely, without the slightest jam. The gear has its place or position, there is a recess in it, which should coincide with the cotter pin.
To check the idling in your case is elementary: assemble the saw and start it with the tire and chain installed. Do not forget to adjust the carburetor if it was disassembled.
First check the ignition, make a clearance of 0.7 mm on the candle and pull the starter, if the spark skips in free air, then the ignition is in order. If there is no spark, change the module (the candle must also be checked). But I think according to your description, the carburetor is to blame.
After already engage in working revolutions. They are similar saws, I think the carburetor is the same. When I adjust, I immediately unscrew both screws by three turns. Further on the circumstance (turn away, wrap). But I advised you according to the instructions.

Husqvarna 137 chainsaw: prerequisites for defects and their repair
The chainsaw has become an irreplaceable and fundamental tool in the daily life of each owner. The popularity of this tool has been growing from the very beginning of its appearance, because with its own functionality to a significant extent it has facilitated the life of every forester, gardener and just.
How to choose a chainsaw is not an easy one, the assortment of products is simply enormous, because many have difficulties when buying this product. After all, hunting is not just about buying a chainsaw, but also investing your money profitably, and acquiring a really reliable and convenient thing. If you decide to acquire this kind of equipment, and do not understand what to pay attention to when buying, then this article is for you.
Here you can find answers to your questions regarding the technical features of one of the most popular models among chainsaws. Husqvarna 137. This “amateur” version of the chainsaw, more professional is shtil chainsaw.
The undisputed market leader in agricultural tools
Husqvarna is a company that has been producing high-quality tools and equipment for working in the garden for many years, and its products are perfect for large-scale industrial construction.
The assortment of the manufacturer is huge, but the main focus of the company is the creation of chainsaws.
In developing its own “masterpieces”, the manufacturer first strives for quality, and pays considerable attention to innovations related to the production of this kind of technology.
This very feature causes tremendous trust among customers.
The irreplaceable assistant of each of us
Such a model has a significant advantage, and specifically low weight, which contributes to a more comfortable operation, it is also quite economical, because the manufacturer equipped it with an engine (push-pull) which has a small volume. But, without looking at this kind of functionality, the chainsaw is quite powerful. One of the most successful models is the Husqvarna 137 saw.
As for the features of the chainsaw, then her weight is about 4.6 kilograms, despite the fact that this is the “clean” weight of the tool, without the presence of oil, fuel and chain tires. Of course, in a full outfit, the chainsaw will weigh significantly more, but the indisputable advantage can be considered that thanks to the long tire, which has 38 cm, operation becomes easier. This very feature makes it possible to create more in-depth cuts.
The chainsaw of this manufacturer has a very good power which is about 1.6 kW, which contributes to a significant increase in the level of vibrational waves, and this is a significant minus in working with this equipment. Of course, when developing their own products, the manufacturer considered how to reduce this kind of vibration and supplemented the technique with the so-called anti-vibration mechanism.
If we talk about the turns, then in the operating mode their number is 13 000, and in running condition. 3000.
Inventory management is done using a double-lever design with an integrated starter, which, in truth, is rather awkward, because it is difficult to get to certain parts due to its location during maintenance. Choosing a cheap chainsaw for the home is no easy task. If you decide to suspend your own choice on this model, then you will have to pay a considerable amount for such a chainsaw, because it is one of the most expensive in the range of products manufactured by this manufacturer. You can get acquainted with the for chainsaws produced in Russia here.
If you finally turned your dream into reality and got for your own household such an irreplaceable assistant as the Husqvarna 137 chainsaw, then it is time to familiarize yourself with all the possible breakdowns and how to eliminate them. After all, as they say, it is necessary to be prepared for everything and breakdown can take place at the most inopportune moment.
Today, there is an unlimited number of workshops that are engaged in the repair of this kind of equipment, but it takes time to get your chainsaw in good condition, and besides will have to pay a certain amount for the service.
But, you must admit, it is much more economical and easier to repair the Husqvarna 137 chainsaw with your own hands. In fact, if the breakdown is not significant, then there is no point in wasting money, but you can easily fix the breakdown. And in order for you to at least have the idea that with your equipment and how to make “first aid” below, we will provide more and more common faults and annotations for the repair of Husqvarna 137.

Join a group in contact, share experiences, ask questions.
In this you see the disassembly annotation:
Ignition system failure
If you encounter a malfunction of the chainsaw, first check the spark plug. But you need to do this very carefully, using a special hook, having previously disconnected the wire. The most important thing that you should pay attention to is directly on the appearance of the candle.
A dry surface indicates that the fuel has ceased to flow into the cylinder, therefore, the problem of breakage is not in the candle, so it must be screwed back.
But if candle covered with fuel spray, this indicates that the problem is either in the carburetor, the adjustment of which was not carried out correctly, or the start rule is violated.
In order to eliminate this kind of malfunction, you need to thoroughly wipe the spark plug, shut off the fuel supply and turn on the starter. This is done in order to ventilate the combustion chamber and get rid of fuel surplus. After that, the cleaned candle must be replaced and the chainsaw started.
And the last thing that can happen to a candle is that it can be covered with soot, which indicates that you are using low quality oil, which is not permissible if you want the tool to serve you for many years. Also, the reason for this may be an error in the calculation of oil and gasoline, and an incorrect carburetor adjustment process.
In this case, you should clean the candle, rinsing it with an awl and rid it of carbon deposits, then wipe the electrodes with a skin and put them in place. In addition, it is important that the gap directly between the electrodes and the candle should not exceed 0.5. 0.65 mm, otherwise a new gasket must be installed.
It is important to pay attention to whether a spark is present. For this kind of manipulation, you need to put the ignition cable directly on the spark plug, then connect the cylinder and the nut located on the spark plug with pliers and start the starter.
Then sparks should appear, but if they are absent, then in this case there is a problem of a chainsaw malfunction in the candle, which must be replaced. But there are cases when, even after replacement, there is no spark, this indicates that the high-voltage wire is faulty or the direct connection to the candle is broken.
Fuel system failure
There are situations when fuel does not enter the cylinder, such a malfunction can occur for the following reasons: firstly, a dirty filter (fuel). In order to clean it, you must first remove the hose (fuel), and then check how well the fuel flows. Since through this manipulation, you can find out what is the cause of the breakdown.
Since if there is a weak stream, then the reason is in the filter, that is, it needs to be cleaned. For this, it is necessary to get it directly through the tank, namely through its fuel hole. Naturally, it is possible to reduce the likelihood of contamination, but for this it is necessary to carry out periodic preventive measures, namely it is advisable to replace the old filter with a new one at least once every three months. The cause of the breakdown may also be insufficient oil viscosity for the chainsaw chain.
May also occur in breakage clogging special holes, which is located on the fuel tank, namely on the cover. This kind of hole is called a breather. You can check whether it is working or not by disconnecting the hose, and then clean it with a needle. It is also worth noting that there are several causes of failure, one of which is pollution of the filter (air).
Therefore, air does not enter the required amount directly into the carburetor, this leads to the fact that the process of motor work is disrupted. If you encounter a problem when the chainsaw stalls while adding gas, details are here.
In order to clean the filter, it is necessary to rinse it and clean it in clean water, but this must be done very carefully. Then it is very important to dry it and install it in place. And also the cause of the breakdown may be incorrect adjustment of the carburetor, which must be done with three screws.
But remember that each manipulation must be carried out, using the instructions, since otherwise you can only aggravate the situation.
And the final cause of the breakdown is considered to be clogged channels or the integrity of the carburetor membrane is violated.
If your chainsaw starts and stalls, the reason for the is here.
If you are faced with a situation where the engine works perfectly directly at low speeds, and if you increase the speed then it starts to stall, then the spark arrester is faulty.
The spark arrester located in the silencer is most likely clogged with combustion waste.
In order to clean it, you must first remove the muffler, and then disassemble. It is worth remembering that there are models that can not be disassembled. After you took out the muffler need to be cleaned of soot, by means of detergents, after washing, be sure to dry it with a hairdryer, and after the manipulations are finally finished, it is necessary to put it in place.
Undoubtedly, a chainsaw occupies an important place in the everyday life of each of us, especially when it becomes necessary to carry out certain works on garden plots. Chainsaw rating by quality. See here.
And if you are going to purchase a chainsaw for yourself, then you will make the right choice and you will not regret it for a second.
First of all, what I would like to draw your attention to, since this is that this kind of tool will serve you well for various kinds of manipulations related to wood sawing, logging and garden processing.

Husqvarna 236 repair manual
Husqvarna 236 chainsaw adjustments
Question: I recently purchased a Husqvarna 236 chainsaw, at the moment I don’t understand how to run it in correctly.
The instruction manual says that it is necessary to run-in within 10 hours without allowing the chainsaw to work at maximum speed.
At the same time, the same instruction also states that it is necessary to saw a tree at maximum speed, as you all understand. Or for 10 hours to drive her at idle? Although I heard that you can’t run in at idle. How right?
Answer: in the instructions, we are talking about the maximum engine speed. That is, in the presence of a large load, it is necessary to give full gas and load the saw so that the speed drops to the workers.
But when sawing a tonometer, construction work and where the load is knownsmall, it is better to hold a little gas, so as not to spin the engine.
And in no way should one give full throttle without any load at all. This is only allowed with the Husqvarna 236 saw when adjusting the speed.
Indeed, you can’t run in at idle. Nagara forms a lot. And if you drank after this two weeks and still stand, then the chance to break is pretty high. And if you play with gas while running in. Listen to the saw.
If the speed is low. The clutch will slip. It grasps normally only at speeds above average. So you can set the clutch on fire, then it will be bad to hold.
Just let the saw rest for more often. Short cuts to a third of the tire. 20 seconds break. Do not try to work until an empty tank. Saw does not like this. And at the end of the work, it is necessary two minutes at idle, so that the saw cools down.
Question: The problem with the Husqvarna 236 chainsaw. Normal speeds are gained after the flow rate is about a third of the tank. Before that slows down, what could be the reason? I clean the air filter, gasoline 92 pour.
Answer: Most likely, the carburetor requires adjustment. It would be clearer if this happened immediately after the launch, but, nevertheless, it seems. What about the launch? And right after launch, if you give full throttle, is there immediately acceleration or failure?
For example, if there are dips immediately, and after half a minute the acceleration is normal, everything is normal with the L jet. And idling should be distinct. And after running in the carburetorregulated?
On this technique in most cases is required (new sophisticated engines). And it would be nice to check the fuel filter.
Question: Husqvarna 236 saw is completely new, worked for a maximum of 20-30 minutes, and then as tests.
Today I tried to make new gasoline and oil. Poured without results, does not even grab it, noticed that there is no gas in the primer, and when I press, the whistle is heard, but it is empty.
He took it off, pulled off the phone, from there a stream of gasoline. Then he put it in place, like pumped gas, started it, worked exactly how much gas pumped.
It turns out the feed goes through the primer to the carburetor? And then how does it start, does gas itself come under pressure? What to do?
Answer: Look carefully if the fuel line is not bent somewhere, and look in the tank too. Maybe the engine of the Husqvarna 236 chainsaw is already flooded and therefore does not start. If flooded, dry and try to start from a half-gas position and with an open air damper.
Sorry, there is no certainty whether you are doing everything correctly at startup. It is unlikely that the saw was defective.
It sometimes happens that the carburetor needs to be adjusted not after running in, so to speak after a few liters of fuel, but immediately after purchase or after some time. To a greater extent applies to x-torc and 2 mix.
I can’t know for sure for your specific case, but such a phenomenon is not rare enough. Who comes with a similar problem, I advise you to always use the same high-quality gasoline and oil and not to change them, and I set up a carburetor on the same gasoline. It usually helps.
Question: I bought a Husqvarna 236 chainsaw. My first saw. Collected, filled (all original). Does not start, does not even grab.
According to the experience of using gas technology, I started it like this. I sucked it out and pulled it until it was exhausted. In fact, everything is different, and the procedure is described in the instructions and on the saw cover.
At first it died out when the gas was released, but I attribute it to the first start and the filled candle. When working, vibration is not very transmitted to the hands, it is nice. Noise is not very strong. The chain was first pulled, as in the instructions. Sawed, trial, three planks. The chain sagged significantly.
As a result, she flew away from me, and on a pair of slots that go into the tire, badass appeared. Accordingly, it no longer enters the bus. You need to straighten with a file. Tell me, what is the chain tension order so that it does not sag during the first start-up?
Answer: Tighten by lifting the tire. By the way, with a stretch of the new chain there is such a procedure as its running-in.
Most often, nobody talks about and writes about her anywhere, but in vain. It is supposed that while the chain is completely new, put it on the tire and simply pour oil on top without sparing it.
We start the saw and drive at medium speed for about half a minute. We stop, tighten the chain, water again with oil and for another minute at medium speed. And so four times.
Question: I bought and operate a Husqvarna 236 chainsaw. A sensor hangs in the gas tank at the saw. It should be?
Answer: Not a sensor, but a fuel filter. Dangles on the fuel line.
In no case do not leave the mixture in the tank for more than a day, even a quality one! After work, drain everything and produce residues in the carburetor, as the model is very capricious and requires compliance with the operating rules according to the instructions literally to the point.
There is a Tork engine, and when starting in the middle position of the air damper, it is necessary to warm up for 10-15 seconds at elevated ones before dumping at idle speed to start optimal circulation
Question: Perhaps it’s more likely not by the problem, but by the operation of the Husqvarna 236 saw. There is an anti-vibration system that essentially unties the handle of the saw from the engine with the tire.
So, when trying to make a clear vertical cut perpendicular to the beam / log, due to the elasticity of this decoupling, the tire deviates from the handles under load.
It turns out that mine, at the beginning an even cut, goes to the left both vertically andperpendicularity. Hands hold the saw evenly, try, at least. Is it really a matter of saw? And what to do to nevertheless saw straight and straight?
Answer: Sharpen the chain first, should help! If the chains are new, then you can check the integrity of the screws and the spring shock absorbers themselves, screw seats.
In the springs are rubber bushings, the thread may be cut off or the screw just fall out. You also need to remove the plastic holder and check for cracks and damage. One could look at the tire, its fastening and whether there is radial play in the bearing.
Question: I looked at the specifications, the cylinder volume of the Husqvarna 235е saw was 34.4, and that of 236 and 240 38.2. Therefore, the question is: can it be put on 235 CPGs from 236, provided that the overall and landing dimensions allow this to be done?
Answer: It is possible, there the stroke length and everything else is the same. Just like on Huskvarna 137 you can put a cylinder from 142.

A chainsaw is a tool that will always come in handy on the farm, especially if you live in your own home or you have a summer house.
Using a chainsaw, you can easily and quickly harvest firewood, chop down trees and carry out repairs. Depending on the functionality and scope of the chainsaw are divided into three main classes: household, semi-professional and professional.
Husqvarna 236 chainsaw: features, specifications and DIY repair
Household chainsaws, as a rule, have low power and are designed for an average of 20 hours of operation per month (about 40 minutes per day), but at the same time they are very light and easy to handle. Semi-professional chainsaws are able to cope with any work, but they can not work for 8-10 hours a day for a long period. Professional chainsaws are made of durable and wear-resistant materials, which allows them to work up to 8 hours without a break.
In our catalog we have collected the best chainsaws of the most popular brands: chainsaws Stihl, Makita, Interskol, Husqvarna, chainsaws Ural, Friendship and other brands.

Husqvarna 236 chainsaw malfunctions
Recently I bought a Husqvarna 236 chainsaw, at the moment I don’t understand how to run it in correctly. The instruction manual says that it is necessary to run-in within 10 hours without allowing the chainsaw to work at maximum speed.
At the same time, the same instruction also states that it is necessary to saw a tree at maximum speed, as you all understand. Or for 10 hours to drive her at idle? Although I heard that you can’t run in at idle. How right?
In the instructions, we are talking about the maximum engine speed.
That is, in the presence of a large load, it is necessary to give full gas and load the saw so that the speed drops to the workers. But when sawing a tonometer, building work and where the load is obviously small, it is better to hold a little gas, so as not to spin the engine. And in no way should one give full throttle without any load at all.
This is allowed only at the service when adjusting the speed. Indeed, you can’t run in at idle. Nagara forms a lot. And if you drank after this two weeks and still stand, then the chance to break is pretty high. And if you play with gas while running in. Listen to the saw. If the speed is low. The clutch will slip.
It grasps normally only at speeds above average. So you can set the clutch on fire, then it will be bad to hold. Just let the saw rest for more often. Short cuts to a third of the tire. 20 seconds break. Do not try to work until an empty tank. Saw does not like this. And at the end of the work, it is necessary two minutes at idle, so that the saw cools down.
The problem with the Husqvarna 236 chainsaw is that normal speeds are gained after the consumption of about a third of the tank.
Before that slows down, what could be the reason? I clean the air filter, gasoline 92 pour.
Most likely, the carburetor requires adjustment. It would be clearer if this happened immediately after the launch, but, nevertheless, it seems.
What about the launch? And right after launch, if you give full throttle, is there immediately acceleration or failure? For example, if there are dips immediately, and after half a minute the acceleration is normal, everything is normal with the L jet.
And idling should be distinct. And after running in the carburetor adjusted? On this technique in most cases it is required (new sophisticated engines). And it would be nice to check the fuel filter.
Saw Husqvarna 236 is completely new, worked for a maximum of 20-30 minutes and then as tests. Today I tried to start a new gas oil. Poured without results, does not even grab it, noticed that there is no gas in the primer, and when I press, the whistle is heard, but it is empty.
He took it off, pulled off the phone, from there a stream of gasoline. Then he put it in place, like pumped gas, started it, worked exactly how much gas pumped. It turns out the feed goes through the primer to the carburetor? And then how does it start, does gas itself come under pressure? What to do?
Look carefully if the fuel line is bent somewhere, and look in the tank too. Maybe the engine is already flooded and therefore does not start.
If flooded, dry and try to start from a half-gas position and with an open air damper. Sorry, there is no certainty whether you are doing everything correctly at startup. It is unlikely that the saw was defective. It sometimes happens that the carburetor needs to be adjusted not after a break-in, so to speak after a few liters of fuel, but immediately after purchase or after some time. To a greater extent applies to x-torc and 2 mix. I can’t know for sure for your specific case, but such a phenomenon is not rare enough.
Who comes with a similar problem, I advise you to always use the same high-quality gasoline and oil and not to change them, and I set up a carburetor on the same gasoline.
It usually helps.

I bought and operate a chainsaw. In the tank for gasoline at the saw dangles some kind of sensor. It should be?
Not a sensor, but a fuel filter.
Dangles on the fuel line.
The problem with the Husqvarna 236 chainsaw is this: normal speeds are gained after the consumption of about a third of the tank.
Before that slows down, what is the reason?
If you saw a new one and there are no sharp jumps in revolutions and other failures, then there can be no problems, just carefully monitor the proportion of the mixture and the quality of fuels and lubricants, regularly check the filters. In no case do not leave the mixture in the tank for more than a day, even a quality one!

I bought a husqvarna 236 chainsaw, it starts very tight, in order to start it you have to pull the cable with full force, the master started it, he said that was normal for Husqvarna.
The cable naturally comes out in cycles, because of this the whole saw runs on the floor. Tell me, please, is it worth further to use such a chainsaw?
Do not worry and do not spare the starter. If you don’t pull straight away and divide the movement into two. A small pull of the dogs to the hook and a sharp jerk to launch, then nothing will happen to him. Press the saw harder, make a jerk sharper. If you pull immediately, without a preliminary hook, then the starter coil will end quickly.
Perhaps more likely not on the problem with the saw, but on the operation of the Husqvarna 236.
There is an anti-vibration system, essentially untying the handle of the saw from the engine with the tire. So, when trying to make a clear vertical cut perpendicular to the beam / log, due to the elasticity of this decoupling, the tire deviates from the handles under load.

Repairs chainsaw yourself like repair a chainsaw on your own? Common Chainsaw Malfunctions
A chainsaw is a tool that no builders, no rescuers, or ordinary summer residents can do without. The first chainsaw is needed for the construction of structures, the manufacture of construction “scaffolding”, the second often have to use this tool to save drivers who got into an accident. Amateur gardeners also purchase chainsaws for harvesting firewood for a bath, pruning overgrown tree branches. When tools do not hold a large-scale “front of work,” they do not simply break down. Is an ordinary user like us able to find the problem on your own without fixing the chainsaw? What kind of malfunctions of a chainsaw can you fix yourself? This article will help to answer all the identified problems.
Any chainsaw, even if it is a model of a European brand (Stihl, ECHO, Husqvarna) according to another domestic manufacturer (Ural, Cedar, etc.), has the same your appearance. This is the case, inside which there is an engine not a fuel tank, on the outside of the handle (there may be an additional one), a starter, a saw bar with a chain. With a sharp jerk of the cable, the engine starts to work, saw blade comes into action.
However, there are several situations where this does not happen. In these cases, you will observe the following picture:
– the tool is jammed in the cut;
– the saw does not start at all;
– it begins to function, but quickly stalls;
– The chainsaw works with insufficient power.
The reasons for this you like a lot. It is necessary to deal with all of them separately.
How to disassemble the Husgvarna 236-240 Chainsaw https://vk.com/remontinstrumenta74
Join a group in contact, share experiences, ask questions.
1. If you encounter then that the chainsaw is stuck inside an impressive log, it makes no sense to panic not to try to pull it out. It could be damaged saw bar, in addition, the entire tool will become inoperative. Turn it off, wait until the blade stops completely, do not carefully remove the tire from the cut. You, the cause of this situation were dull chain links. And then you just need to replace the saw blade with a new one.
2. With a problem, our simple forgetfulness will serve. Be sure to check the presence of fuel in the tank before switching on. As this may be the reason that “the saw will not start!”
A more serious problem is a defective carburetor. To understand whether it is operational, unscrew the spark plug. If the oil is similar to dry, in other words, on the contrary, it is too “wet”, soot is present on its surface. This indicates incorrect regulation of the carburetor. Set it up correctly. Remember also that the gap between the electrodes in the candle should be 0.5-0.65 mm. If this is not to such an extent, this will also serve as the reason for the “failure” of the tool to work.
The ignition system may also fail when. To diagnose it, turn out the candle, put a cap on its surface with the contact, and do not pull the cable again. If there is no spark, you, the problem at this time lies in the ignition unit.
3. Remember that 2-stroke saws work on the so-called. “Fuel mixture”, and not on pure gasoline. If you have such a chainsaw, observe the proportions when preparing the mixture. The correct ratio of gasoline to oil in a certain model is indicated in the instructions. Otherwise, the engine will not receive the necessary lubrication, the saw will not stall.
4. Lack of power (or work “half the force”) and possibly caused by poor condition of the piston rings. If they hang loose enough inside the cylinder (this can be checked by slightly shaking the part), it’s time to purchase parts.
As we see, everyone who is familiar with this tool not by the principle of its functioning will be able to independently establish the problem and not cope with its solution. However, if you do not have a technical education and not working skills with a chainsaw, it is better to trust repairs to professional specialists. So there is an option to protect yourself from the consequences of improper actions, to prevent the probably disastrous results not to save on buying a new tool.
Diagnostics and troubleshooting, adjustment and repair of chainsaws
Having become the owner of a chainsaw, you must initially be prepared for the difficult moments that inevitably arise during a rather long operation. For a rugged owner of questions with the use, service and repair of a chainsaw with their own hands, there is simply no.
This is not such a relatively complicated gasoline unit, so that a man who respects himself is not able to successfully cope with it. Over, of course, a valuable acquisition was not completely random, but deliberate. With a preliminary study of the topic on the official websites, a deep acquaintance with the experience of experts in this field, with an in-depth study of the device of a chainsaw.
Most of the work is done. The idea of the design, key systems, the basics of operation is information and technical baggage, which allows not only to successfully use the chainsaw, but also to properly maintain and repair it, as necessary, to the best of its ability and ability. Consider the malfunction of the Stihl 180 chainsaw and its repair.
Since the engine is source of driving force for chainsaws, problems with it constitute the lion’s share of failures. We list the most common problems.
Chainsaw won’t start
Why does not the chainsaw start, even if everything is done correctly, in accordance with the instruction manual? The working mixture was prepared in the right ratio, according to the requirements of the manufacturer, and poured into the tank. Closed air damper to obtain an enriched working mixture. Pumped up fuel with a hand pump. The ignition is switched on with the corresponding button. Made several vigorous jerks with the starter handle.
I would like to draw the attention of beginners to chainsaw launch process. If everything is done correctly, then when starting the engine at the moment the fuel enters the cylinder, additional resistance will be felt on the starter handle. It arises because when moving up before setting the candle on fire, the piston pre-compresses the working mixture, and the resistance increases sharply. On this basis, we can already say that:
- Fuel enters the cylinder.
- The piston group is still alive and has some kind of compression, the exact value of which we can only judge by measuring with a compressometer.
Based on these conclusions, we can make an assumption that if there is fuel in the cylinder and the engine does not start, the reason is probably a candle.
We also recommend reading:
We twist the candle with a special key from a set of tools and evaluate its condition. The normal color of the center and side electrodes of the candle is light brown. All other options indicate deviations in individual engine systems. There are three possible options for the state of the candle:
- Candle is clean and dry.
- The candle is covered with fuel and is wet.
- The candle is covered with black soot.
If the candle is clean and dry, then probably the fuel does not enter the cylinder for the following reasons:
- A vacuum is created in the tank due to clogging of the hole in the tank cap, which communicates the cavity of the tank with the atmosphere.
- The fuel filter is dirty.
- The jets or carburetor channels are dirty.
Eliminate the causes
- We clean the hole with a thin wire or a needle.
- We remove the fuel filter from the tank, inspect it. If it is clogged, then blow it off or rinse it off from dirt.
- We disassemble the chainsaw, remove the carburetor, eliminate clogging.
In fact, a carburetor is a rather complicated device, the repair of which is advisable to be entrusted to a specialist, and it is better to adjust it, of course, on a special stand. But the rest of the repair operation, for example, Husqvarna 142 chainsaw, and partner DIY chainsaw repair are fully accessible and do not require additional equipment.
If the spark plug is coated with fuel and is wet, this is a clear sign that there is too much fuel in the cylinder. The chamber volume is supersaturated with its vapor, and it cannot ignite from the discharge of a candle due to a violation of the proportionality of the ratio of gasoline and air. The reasons are as follows:
- The air filter does not allow air through due to contamination.
- The carburetor adjustments are broken.
- The candle does not work.
Eliminate the causes
- When the piston moves downward, there is a cycle of suction of fuel and air into the cylinder. If the air filter is clogged or dirty, then the working mixture becomes so enriched that it fills the candle on a chainsaw due to lack of air. Fuel loses its ability to ignite. In this case, the malfunction can be eliminated by cleaning or replacing the filter.
- When repairing, the Stihl 180 is available for DIY repair only by adjusting the idle speed. If the problem is somewhere inside the carburetor, then because of the high complexity of the process, you need to use the services of specialists. When repairing a Husqvarna 142 chainsaw with your own hands, three carburetor adjusting screws are available. For low, high and idle speeds.
- To check this, unscrew the candle, put on it a high-voltage wire, and connect the hexagon of the candle to the cylinder, providing contact. We try to start the saw several times. At the same time, we observe the presence of a spark. In its absence, replace the candle and re-test. If it turns out that there is no spark, then we revise the high-voltage wires and the ignition unit. Since these defects can be eliminated only by replacement, and not by repair, we do so.
The candle is covered with carbon, mainly due to excess oil in the fuel. The engines of chainsaws, in the vast majority, are two-stroke and operate on a fuel mixture consisting of gasoline and oil. You just need to adhere to the recommendations of the manufacturer and accurately measure the components. Do not use freshly prepared solutions. If there is fuel left in the tank and a break in operation is expected for at least more than a week, drain it, excluding storage. In the process of irreversible chemical reactions, it loses the necessary properties and only harm the chainsaw.
Cleaning candles from soot it is made by a scraper from soft materials. Copper, plastic, hardwoods.
The engine does not develop full power
Such a defect appears mainly on chainsaws that have been operating for a long time.
- The piston group is worn out.
- The silencer has lost bandwidth.
- The carburetor adjustments are broken.
We diagnose and eliminate defects
- In order to determine the condition of the piston group, it is enough to remove the muffler by carefully inspecting the piston with rings and the cylinder mirror. If scratches, chips, traces of peeling deposits are noticeable, then replacement is probably required. You can judge about this exactly by compression. It is measured by a compressometer, and its value should be from 8 to 10 atmospheres. With values at the level of 5 atmospheres, a chainsaw can only function at idle.
- As a result of long work in the muffler, carbon deposits from the combustion of the fuel mixture accumulate and compress. Periodically it accumulates so much that the exhaust gases do not have time to empty the cylinder during the purge. Thus, the optimal composition of the fuel mixture is violated. Combustion is incomplete with low energy release. Hence the power loss. The way out of this situation is the dismantling and cleaning of the muffler chemically or physically.
- How to restore carburetor adjustments described above.
At the time of increasing speed the chain remains stationary. There is only one solution. Just replace the clutch with a new one.
Violations in the chain drive system
The chain pulling system is so simple that there is almost nothing to break if the operating conditions are met. Consider the main problems.
From other manufacturers, the chainsaw broach system Partner, Stihl, Huskvarna are not much different. The same lubrication requirements are maintained as for all. Due to the fact that the chain operates under harsh conditions, failures in the lubrication system lead to its premature wear.
The causes of the malfunction are as follows:
- Failure of the oil pump.
- Clogged oil lines and channels.
- Due to prolonged use in harsh conditions, parts of the oil system fail, leading to oil starvation of the chain. Oil lines crack, fastenings weaken, oil leakages increase. Repair consists in the timely detection of these defects. Cleaning of oil channels from sawdust and debris for unimpeded supply of oil to the chain.
- To check the normal oil supply, you need to start the chainsaw and, keeping it above a clean surface, add revolutions until the clutch engages and the chain starts to move. Increase speed to maximum. After turning off the saw, inspect the surface for traces of oil scattered by the chain. Their presence indicates the operation of the lubrication system.
Any malfunctions are surmountable, only there would be a desire to understand them. Repair of the Stihl 180 chainsaw and repair of the Husqvarna 142 chainsaw on your own is quite affordable.
