Chainsaw Husqvarna 137

In what cases does the carburetor of a Husqvarna chainsaw require adjustment?

There are a lot of problems that can be solved by adjusting the carburetor. Adjusting the carburetor of the Husqvarna chainsaw is necessary when malfunctions such as:

• increased idle speed;
• strong smoke when operating the tool;
• difficulty starting a cold or hot engine;
• lack of traction and reduced maximum speed.

This is by no means a complete list of problems that can be solved by tuning the Husqvarna carburetor. In some cases, adjusting the quality and quantity of the fuel mixture is carried out after a major overhaul of the engine or during scheduled maintenance of the 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.

Screws (L) and (H) cannot be adjusted without specific knowledge and experience. Incorrect adjustment of the quality and quantity of the fuel mixture can cause the engine to stop working or operate incorrectly, causing it to wear out quickly or even seize.

Husqvarna 142 chainsaw device

The Husqvarna 142 chainsaw is equipped with a motor that uses patented X-Torq technology. As a result, the engine consumes less fuel without loss of efficiency and economy during operation.

Husqvarna uses an air injection system to cool the engine, which increases air filter change intervals and reduces wear on critical engine parts. To reduce vibration, the saw is equipped with another proprietary technology. LowVib. It consists of several shock absorbers that act as shock absorbers.

The Husqvarna 142 saw comes with a Japanese Walbro carburetor. It is characterized by durability and increased volume, which allows you to prepare a large amount of fuel mixture in one cycle.

The engine is started using a manual starter. Thanks to the SmartStart function, its resistance is reduced by 40%. The starter cable is located behind the tool. Next to it are other controls. Throttle position switch, throttle lever, and ignition on/off button.

Tires and chains of the brand are responsible for cutting wood. There is a separate sprocket on the side of the chain saw for tensioning the chain. This allows you to adjust the saw element without the use of tools. The chain is lubricated automatically while the saw is running.

All internal mechanisms and spare parts of the Husqvarna 142 are housed under a durable housing made of multi-layer plastic. It can withstand low-height drops and accidental impacts against hard objects. For ease of use of the tool, its configuration includes 2 rubber handles.

Roll protection is provided by a guard for the operator's right hand, as well as an effective chain brake. It is triggered immediately when the chain hits nails and other hard objects.

The tool successfully copes with trimming branches and branches, clearing bushes, as well as cutting down trees whose trunk diameter does not exceed 45 cm. The light weight of the saw allows it to be used at high altitudes.

Tools required for work

Before you start setting up the Husqvarna carburetor, you need to make sure you have all the tools that may be useful. To carry out this type of work yourself, you will need:

A regular slotted screwdriver will not work for adjustment, since the adjusting screws on Husqvarna chainsaws can have different cross-sections. You will have to purchase a special one, this is a feature of repairing Husqvarna chainsaws; they did everything so that the saw could be repaired only in a specialized Husqvarna service center.

Why is the Husqvarna chainsaw considered the best model?

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

Any operating instructions discuss the sawing process from a safety point of view. In the household, you need to approach tools with reasonable care. Keep children away from contact with the saw. A saw that is not working or left unattended must be covered with a protective cover.

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.

Algorithm and description of Husqvarna carburetor settings

The Husqvarna carburetor is adjusted in the same way as carburetors on chainsaws from other manufacturers are adjusted.

Immediately before adjustment, it is necessary to conduct a complete diagnosis of the saw and make sure that there is no difficulty in supplying fuel or air leaks into the crankcase of the chainsaw. You also need to make sure that the air filter is clean and, if necessary, replace it with a new one.

The work order is as follows:

1. On the muffled saw, the factory settings of the Husqvarna carburetor are installed.
2. The engine starts and the saw warms up for several minutes.
3. By turning the screw (L) clockwise, the position at which the engine develops maximum speed is found, after which the screw must be turned back 1⁄4. If the chainsaw chain rotates, then it is necessary to reduce the idle speed by adjusting the position of the screw (T).
4. The next stage is adjusting Husqvarna's power at maximum speed and adjusting its quantity. To do this, the tachometer is connected to a running chainsaw, the throttle is squeezed to full, after which the tachometer readings are checked. If the maximum speed value differs from the maximum number recommended by the manufacturer, then by changing the position of the screw (H), the tachometer readings are returned to normal.

How to understand that everything is done 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:

1. Warm up for 5 minutes.
2. By turning screw L, we bring the engine to the highest speed in an unloaded state and return it back a quarter turn.
3. 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.
4. 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.

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:

1. 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.
2. 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.
3. 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.
4. 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.

Nuances of adjustment

After the adjustment, the chainsaw should easily pick up and drop speed, and operate stably at low and high speeds. If the saw chain rotates at idle speed after adjusting the carburetor control screws, this is a sign that the adjustment was made incorrectly and the position of the screw (T) needs to be adjusted.

Also, when adjusting the Husqvarna carburetor, it is worth taking into account the response time of the chainsaw to the rotation of the screws. The settings do not change immediately, but within five or ten seconds.

One of the indicators of incorrect adjustment is heavy smoking when the saw is operating, which indicates a large amount of fuel entering the combustion chamber. If such a situation occurs, the position of the screw (L) must be adjusted.

DIY carburetor repair

If, during a full diagnosis of the Husqvarna chainsaw, carburetor defects were discovered, some of them can be eliminated without contacting the Husqvarna AB service center. For example, you can do this yourself:

• change the gaskets under the covers of the main chamber and fuel pump;
• clean or replace the strainer;
• replace the diaphragm or needle valve of the main chamber;
• troubleshoot the fuel pump diaphragm.

Gaskets, diaphragms and a needle valve with a rocker arm can be found in the repair kit, which is available for each model of Husqvarna chainsaw carburetors.

Also, if you have some experience, you can try to restore a faulty injector valve, but you cannot guarantee a positive result when trying to restore an injector; if it malfunctions, manufacturers recommend replacing the carburetor completely.

The first thing you need to do before removing the carburetor from the Husqvarna is to clean the saw with a compressor, since dirt can interfere with quality repairs. Next, you need to open the top cover of the chainsaw, remove the air filter, and disconnect the rods from the air and throttle valve control levers. After this, unscrew the carburetor mounting screws.

Disassembling the carburetor body for repairs is quite simple. The main chamber cover is held in place by four screws, which can be removed using a regular screwdriver; the fuel pump cover is secured with one wide screw.

Below is a video, after watching which you will understand exactly how you can repair the carburetor without contacting a Husqvarna service center.

• First you need to set the saw switch to the “On” position.
• Then pull the idle air damper lever all the way.
• Pull the starter cord with a sharp movement of your hand (but no more than ten times).
  

  If the sound of the engine is heard before you have completed the 10th dash, you can move on to the next step.

• Next, you need to move the lever to switch modes to the “HalfChoke” position. This will mean that the air damper will be half closed.
• Next, you need to jerk the starter cord until the engine starts.
• After starting the engine, you need to let it run for about five seconds. The engine starter must then be pressed and released to return the engine to idle speed.

To start and configure an already warmed-up engine, you need to:

• Set the saw switch to the “On” position.
• Direct the mode change knob towards o.
• With your right hand you need to pull the cord until the engine starts running.
• Press the engine starter until it returns to idle speed.

Do-it-yourself troubleshooting and repairs

Malfunctions are simple if they do not require disassembling the chainsaw to eliminate them. For Husqvarna 142, the methods for finding them, as well as eliminating them, are no different: it all comes down to checking the condition of the spark plug, the fuel level in the tank, etc.

If easily correctable malfunctions occur, it is necessary to remove individual components, replace or repair them, and then reassemble the Husqvarna 142 chainsaw. This is how the shock absorbers or carburetor are replaced and the starter is repaired. To repair the starter, it is better to first familiarize yourself with its structure, for example, from a video.

If the chain is not lubricated, we recommend watching a video that discusses in detail the lubrication system, its disassembly and reassembly.

If complex faults occur, complete disassembly is necessary. The design of the Husqvarna 142 chainsaw is not complicated, but you must be absolutely sure that for high-quality repairs you can:

• receive drawings of the device with a description and you can do the detailing;
• perform troubleshooting and reassembly.

Is it worth it to repair the Husqvarna 142 piston group yourself? For high-quality overhauls, you must have at least precise tools - a micrometer and a bore gauge - which can cost you more than spare parts. If you decide to do a major overhaul, we recommend watching a video that sequentially shows how to disassemble the Husqvarna 142, and our article on repairing Husqvarna chainsaws.

User manual

The Husqvarna 137 chainsaw, like other models of this brand, is equipped with an inertial automatic chain brake. This part was invented by engineers working at Husqvarna. Nowadays, most manufacturers still produce chainsaws with contact brakes. That is, the brake is activated when interacting with the hand during a reverse impact. In practice, such a contact brake may not work at all.

The autovibration system of this model operates on the principle of “two masses”.

The manufacturer does not produce other systems.

Husqvarna 137 is equipped with a high-profile professional chain. This is another difference from chainsaws with low profile chains. Chainsaws with high-profile chains have a forty percent higher chain. This is especially noticeable with large volumes of work. In addition, such chainsaws maintain high performance even when working with contaminated wood.

One of the most common mistakes when starting a Husqvarna 137 is closing the air damper without turning on the ignition.

It turns out that the fuel mixture enters the cylinder

(see proportions). But there is no spark, no ignition occurs. After this, you will have to unscrew the spark plug, wipe it and screw it back in. Therefore, it is worth remembering that all Husqvarna chainsaws have a combined damper, and the ignition in them will be turned on automatically at the moment when the damper lever is pulled out. There shouldn't be any errors.

Safety precautions

Due to the fact that the Husqvarna 137 is a high-speed cutting tool, it is necessary to adhere to certain safety rules.

To avoid an accident, please read these instructions carefully.

• The spark plug wire must be disconnected during transportation and cleaning. It is important to ensure that it does not come into contact with the spark plug to avoid the circuit suddenly turning on.

Protective clothing for working with chainsaws

• When working with a saw, you must wear protective clothing: shoes with non-slip soles with steel inserts, special gloves (not included in the delivery package), a mask or safety glasses (anti-fog). Hair should be pulled back above the shoulders.
• If you regularly use a chainsaw, you should periodically have your hearing checked by a specialist.
• Chainsaws should only be used by adults.
• Do not place body parts under the saw while the motor is running.
• While the saw is operating, the presence of children and animals must be limited to at least ten meters.
• Do not use a chain saw while under the influence of alcohol, or when you are upset, depressed or tired.
• Do not start work until you are wearing protective clothing and your work area has been equipped.
• You should only work with the saw in a well-ventilated place.
• When you cut down a branch, be prepared to jump back the moment you finish the job so that you do not get hit by the felled tree limb.
• The saw can only be laid on the surface after it has been turned off.
• Before turning on the saw, make sure that the chain cannot come into contact with anything during operation.
• Maintenance of your chainsaw should only be carried out by a specialist.
• The saw handle should be clean and not stained with machine oil.
• The oil and fuel reservoir caps must always be tightly closed.
• Only accessories from .
• Do not smoke while refueling.
• You need to refuel the saw on bare ground in the open air. This is not allowed indoors.
• Before starting the chainsaw engine, you must move ten meters away from the place where the refueling took place.
• Be sure to let the saw cool before refueling.
• If the moving chain touches any object, a kickback may occur - rapid movement of the device down and up. This may result in complete loss of control of the chainsaw and further serious injury.
  

  Therefore, never try to rotate the saw when removing it from the lower cut, and also do not try to cut several logs at the same time.

• Never cut with just the tip of the chainsaw.
• Use guide bars to help mitigate kickback.

“A carburetor is a device responsible for the mixture and supply of fuel to the combustion chamber of an internal combustion engine.”

I am glad to welcome all lovers of “interesting and necessary men's toys”.

Correct carburetor adjustment ensures reliable operation of the chainsaw in all modes and with economical fuel consumption. However, if we remove the word “chainsaws”, then this applies to all internal combustion engines.

Today we’ll talk about how to adjust the carburetor on a chainsaw. In general, such a procedure is performed occasionally. Factory setting is the best and highest quality option. However, if necessary, it is performed by adjusting special screws. Let's figure out how to rebuild it yourself:

This device prepares an air-gasoline mixture in a certain ratio. If this balance is not maintained, then malfunctions occur in the operation of the internal combustion engine (ICE). A mixture that does not meet the standard can be either oversaturated (when the amount of fuel relative to air increases) or lean (when there is more air than required and less fuel).

• The air flow moves through a special channel, and the damper regulates its speed;
• Opening the damper regulates the amount of fuel and air supplied;
• Gasoline and air, flying through the diffuser, are mixed and atomized;
• The resulting mixture flows through the intake manifold into the combustion chamber (cylinder).

Signs and causes of poor unstable performance

Signs of malfunctioning chainsaw carburetor:

• The engine starts hard and stalls quickly. Possible cause: lean mixture.
• Excessive (more than normal) fuel consumption. In addition, intense (more than usual) exhaust emissions. Possible cause: oversaturated mixture.
• The engine doesn't want to run at all. There are two reasons for this: no gasoline (fuel nozzle clogged) or no spark (faulty spark plug, broken high-voltage wire or failure of the electronic unit).

Settings failure itself is rare and the reasons are usually the following:

• Damage to the fastenings of the control screws due to a faulty (damaged) coating of the protective casing. Possible cause: careless touch, rough adjustment attempt, or strong external vibrations.
• Wear of the piston group. Here, of course, adjusting the carburetor will not help much. Consider repairing your engine or replacing your saw.
• Carburetor contamination*. Probable cause: breakdown or unsatisfactory condition of the air filter, use of low-quality fuel, ingress of scale, tiny sawdust, etc. into the fuel channels. *In such cases, the entire fuel system is first flushed, and only then adjustment is made.

The chainsaw starts and stops. Repair methods

If the Husqvarna 142 starts and stops immediately, the main reason for this is wear on the rings, which causes loss of compression. If the engine starts and stops during a cold start, check the muffler as well as the contact between the high voltage wire and the spark plugs.

To fix the problem, you will need to disassemble the saw and inspect the piston rings. If necessary, they must be replaced. It would be a good idea to clean the cylinder walls of residual fuel.

If the rings work, check the contact between the spark plugs and the chainsaw wire. You also need to clean to remove the muffler and inspect its walls. Due to prolonged use of the tool, a thick layer of soot accumulates on the walls of the muffler. In this case, you will need to blow out the element with compressed air from the cylinder.

After completing all the above procedures, you need to assemble the tool and run it. Before using the saw, allow a few minutes to warm up the engine. You can then continue to use the tool as normal.

Chainsaw Husqvarna 142. This is a budget modification that unites the famous Swedish company Husqvarna, which firmly occupies a leading position in the world market. The history of the company began in 1689, chainsaws began to be produced in 1970, at the same time the company began producing gardening tools and equipment. Until 1970, the main specialization of the Husqvarna brand was weapons for the army.

Do-it-yourself carburetor adjustment

In other cases, it is unlikely to guarantee a positive result. The chainsaw carburetor is adjusted with one, two or three screws. It all depends on the brand of saw.

Consider the adjustment option on the popular Husqvarna chainsaw. This carburetor has three adjustment screws labeled:

• T – idle speed control;
• L – regulation of minimum speed;
• H – regulation of maximum speed;

In the first case, there is one “visible” idle screw (T), and the other two (L and H), usually hidden behind the casing. This is no accident. the consumer should make adjustments only with the idle speed screw, since otherwise the optimal factory settings are set. However, for some extreme modes there is still the possibility of adjustment.

The idle speed adjustment screw may be designated by different letters from different manufacturers.
For example, Husqvarna and Partner are designated by the Latin letter “T”, and another well-known manufacturer, Stihl, uses the letters “ LA ”.

Here is a clear picture of the carburetor of the Husqvarna 137 chainsaw:

Hidden lower screws (L and H) serve to adjust the operation of the carburetor in cases where gasoline different from that recommended by the manufacturer is used.

If the octane number is low

– then to increase it, turn the screw from right to left (unscrew it).
This way you can increase power and speed
.

If the octane number is increased

– then to lower it, turn the screw in the opposite direction (tighten it).
This will reduce engine speed
.

The screws are adjusted in this order: L – H – T.

Follow the instructions for your specific chainsaw! It indicates the exact angles of rotation of the screws. This is a mandatory requirement to maintain the best operating parameters of the internal combustion engine.

How to make the adjustment correctly? There is no universal way. This procedure is somewhat different for everyone. However, the process of adjusting any chainsaw can be divided into 2 stages.

1. Basic (carried out with the engine turned off);
2. Final (carried out with the working engine warmed up for at least 10 minutes).

Wrench (screwdriver) for adjusting carburetor screws

Many manufacturers use branded keys. Use them, don't lose them. Finding such a special tool on sale is quite difficult. For example, like the one in the photo on the right...

Be sure to follow the safety rules specified in the chainsaw instructions

.

Candles

Use original ones and change them promptly. This should be done at least once a year. Although, if you look at it more broadly, it all depends on the volume of work performed. Some work almost every day, while others work once during the summer season.

Air filter condition

His condition must be checked, since he experiences a lot of stress during intensive work. Fine wood dust is everywhere. Upon completion of the working cycle, it is recommended to remove it and clean it (rinse).

If it is a polymer (nylon) mesh, then a neutral soap (not foamed) solution is used. Washing is done under running water and dried in the open air (only at “plus” temperatures).

If the “air vent” is made of foam rubber, you can actually rinse it with kerosene, squeeze it out very well and dry it (although the kerosene will not completely evaporate). There are filters made of material similar to velvet mesh. This filter is rinsed in regular warm water without using detergents. Then they dry it.

The new absorbent element (aka filter) must be the same as the used one.
