The device of the Husqvarna 142 chainsaw

One of the main advantages of the 142nd model of the Swedish brand Husqvarna is the competent selection of its components and the high quality of the original assembly. The basis of the garden tool consists of a 2-stroke gasoline engine, the chrome-plated cylinder of which has a volume of 30 cm3. Starting a standard internal combustion engine is done by pulling the recoil starter cable. A proprietary Japanese Walbro brand carburetor with forged jets and an improved fuel injection system is responsible for preparing and enriching the fuel mixture with air in the internal combustion engine configuration. The manufacturer equipped the engine with a fuel and oil tank with a volume of 370 and 190 ml, respectively.

The Husqvarna 142 chainsaw is equipped with a durable clutch, which is responsible for the continuous connection of the engine with the saw set. All spare parts of the mechanism are made of durable steel, resistant to high temperatures and corrosion.

For instant ignition of fuel in the internal combustion engine cylinder of Husqvarna garden tools, a proprietary capacitor ignition system is used, which includes a Champion RCJ7Y spark plug. The distance between the flywheel and magneto electrodes in the operating state of the ignition system is 0.5 mm.

For sawing wood, the Husqvarna 142 chainsaw is equipped with a high-quality saw set made of wear-resistant alloy. It consists of a 38 cm long tire, as well as a chain with a pitch of 0.325". An oil pump operating in fully automatic mode is responsible for the continuous lubrication of the saw set. To allow chain adjustment without the use of hand tools, Husqvarna has provided easy access to the tensioner sprocket. The built-in inertia brake is responsible for the safe operation of the model, which is activated whenever the chain hits a wire, nail or any other solid object.

The Husqvarna 142 chainsaw stands out for its good balance and ergonomics. All switches and buttons necessary for operation are located at the rear of the instrument body. This simplifies the operation of the chainsaw in very limited space.

Operational Features

When operating the Husqvarna 142 chainsaw, you need to take into account its features. This is a simplified semi-professional model, not intended for everyday long-term use. The main area of ​​application of the Husqvarna chainsaw is gardening and housing and communal services - pruning large branches, felling dried trees, etc.

and a power of 2.58 liters. s., air-cooled. It runs on a gasoline-oil mixture in a gasoline to oil ratio of 50:1.

During operation, Husqvarna branded oil is required, but if this is not available, the manufacturer allows the use of any high-quality engine oil, but in a different ratio - 33:1.

The Husqvarna chainsaw has a minimum of controls - there is only a switch, a choke position lever and a combined throttle control lever. This model does not have a primer, i.e. a fuel suction button, which makes starting difficult, but makes troubleshooting easier.

Performance qualities allow you to saw dry and wet wood of various species, including hard ones such as oak and beech. In general, the Husqvarna 142 chainsaw is characterized by high build quality, unpretentiousness and reliability. Malfunctions occur rarely and are mainly associated with incorrect carburetor adjustment or failure of consumables.

Advantages of Husqvarna chainsaws

Chainsaw delivery set

When ordering the Husqvarna 142 model, the buyer receives absolutely everything necessary to start using and further maintain the garden tool. The model kit includes:

• branded tire and chain;
• plastic tire cover;
• hand tools for assembly and maintenance;
• user manual.

For an additional fee, the manufacturer supplies the chainsaw with a bag for transportation, branded oil for 2-stroke engines and additional spark plugs.

Adjusting the carburetor of the Husqvarna 142 chainsaw with your own hands

In order for the 142nd model of the Husqvarna brand to work properly, its owner must promptly adjust the chainsaw carburetor.

This should be done in the following cases:

• if the Husqvarna 142 chainsaw does not start;
• if the engine starts but runs intermittently;
• if the engine starts and stalls when you press the gas trigger;
• if fuel consumption increases sharply.

All these malfunctions threaten more serious breakdowns, which will be quite difficult to cope with on your own and without the necessary experience. To prevent this, you need to adjust the element responsible for enriching the fuel mixture with air. Setting up the carburetor of the Husqvarna 142 chainsaw should be done in the following sequence:

1. First you need to set the Husqvarna chainsaw carburetor to factory settings. To do this, with a cold engine, you need to turn the adjusting screws as indicated in the model’s operating manual;
2. After this, you need to start the saw motor and give it 5 minutes to warm up completely. After this, you need to slowly turn the screw “L” until the engine starts to operate at maximum idle speed. Immediately after this, screw “L” must be turned out 1/4 turn in the opposite direction;
3. If the chain on the bar then rotates, the operator will need to begin turning the "T" bolt one at a time until the chain stops;
4. Next you need to find the maximum engine speed. To do this, you need to hold the gas trigger and start turning the “H” bolt until the engine begins to operate stably at high speeds. After this, screw “H” must be turned out 1/4 turn in the opposite direction.

After adjusting the carburetor, you need to turn off the Husqvarna chainsaw engine and start it again. To check engine operation, the operator must press the throttle trigger sharply several times. If, when the trigger is pressed, the engine quickly gains speed and loses it when the trigger is released, then the adjustment of the standard carburetor was carried out successfully by the operator.

Model specifications

The Husqvarna brand chainsaw in the proprietary 142 modification has solid factory parameters.

These include:

• petrol engine power – 2.58 liters. s./1.9 kW;
• idle/maximum speed – 3000/13000 rpm;
• The manufacturer's recommended length of the tire used is 30–38 cm;
• weight with filled fuel and oil tanks – 4.9 kg.

Despite the impressive maximum speed parameters, the engine of the Husqvarna model is quite quiet. When operating the model under maximum loads, the sound impact level on the operator is 105 dB.

Chainsaw malfunctions and how to fix them

Owners of the Husqvarna 142 model often encounter typical breakdowns caused by improper use of garden tools or simple wear of its parts.

These malfunctions include:

• the chainsaw does not start - the cause of this breakdown lies in the spark plug being flooded. To be able to start the saw motor, you need to remove, wash and dry the spark plug. After this, you need to blow out the cylinder by sharply pulling the starter cable several times with the spark plug turned out. After this, you need to screw in the spark plug and start the engine of the garden tool;
• increased vibration during operation of the saw - repair of this breakdown is carried out by cleaning or replacing the muffler. You will also need to inspect the springs of the anti-vibration system. If necessary, sagging parts must be replaced;
• shooting sounds - if loud popping noises are heard during operation of the Husqvarna model, then the causes of the breakdown should be sought in the carburetor or muffler. The operator will first need to adjust the carburetor. After this, you need to remove and wash the muffler;
• leakage of oil to lubricate the chain - to eliminate this breakdown, you need to check the condition of the oil pump and pipes. The faulty part will need to be replaced.

To avoid further breakdowns of the Husqvarna 142 chainsaw, you need to use high-quality gasoline and oil to refuel it. This will help prevent increased wear of parts and protect model components from overheating.

Most common problems

The most common problems with Husqvarna chainsaws include:

• incorrectly adjusted carburetor;
• malfunction of the ignition unit;
• fuel unit malfunctions;
• unadjusted clutch mechanism;
• oil system malfunctions;
• Incorrect starter operation.

These problems lead to malfunctions of the chainsaw.

The saw does not start or stalls after pressing the accelerator. Possible causes are a breakdown of the starter (in this case it is not repaired, but replaced with a new one), contamination or breakdown of ignition system elements, faulty spark plugs or coil. The most common faults are spark plugs. Another option is difficulties in supplying fuel; the most likely is a clogged fuel filter or a pinched fuel hose from the tank to the carburetor. The gas tank breather may be clogged.

Difficulty starting, white smoke appears. The cause of these malfunctions is an incorrectly adjusted carburetor, supplying too little or too much fuel mixture, or preparing it in the wrong proportion. A sign of this is white smoke from the engine compartment.

Chain spinning when idling. Causes of the malfunction: unadjusted or failed clutch mechanism, unadjusted idle speed, air leaks into the carburetor or crankcase.

Saw chain lubrication problems. They are expressed in the absence of lubrication or the chain coming out in a dirty state. The causes of this malfunction are various - a breakdown of the oil pump, blockages in the breather (hole in the oil tank cap), oil channel or filter, or a malfunction of the oil drive gear.

Why you need to tune your Husqvarna carburetor

The carburetor is one of the important mechanical components that make up a chainsaw. In his tasks. mix fuel with air and feed the resulting composition into the engine. But during the operation of the chainsaw, situations arise when adjusting the Husqvarna carburetor becomes necessary. Depending on the reasons, the carburetor adjustment of chainsaw 142 and other series is performed to prevent the following situations:

Since the carburetor affects the quality of the fuel, in the first case the need for carburetor adjustments on the 137 saw or other professional series such as the Huskvarna 240 or 260 involves affecting enough combustible raw material entering the carburetor to mix with the air mass. It is known that maximum performance is possible only with a certain ratio of these substances. The second point in adjusting the carburetor mixer chainsaw is due to the lack of incoming air, which causes underheating of the injected gasoline and its output in the form of thick smoke. Timely changing the parameters with your own hands to reduce the amount of introduced fuel will significantly reduce the consumption of this product.

A chainsaw is an indispensable assistant for every real owner.

Since the instrument's inception, its popularity has grown rapidly.

Thus, the Husqvarna 142 chainsaw has the highest functionality. It is widely used not only in forestry, but also on private plots.

Choosing a chainsaw is quite simple. So, it is best to focus on well-known brands such as Husqvarna. This company produces a wide range of such tools. Husqvarna 240 and other models are of the highest quality and functionality. But, unfortunately, even such tools are not immune from breakdowns.

Husqvarna saw disassembly algorithm

The process of disassembling a Husqvarna chainsaw is quite simple. In order to do everything correctly and not break parts of the housing or CPG, it is necessary to disassemble in the following order:

1. Top cover.
2. Chain and saw brake cover.
3. Starter.
4. Flywheel and clutch.
5. Front handle.
6. Carburetor.
7. Oil pump.
8. Engine.

Depending on the Husqvarna model, the disassembly procedure may vary slightly.

Important: before you start disassembling the chainsaw, you need to clean it. When using a saw, a lot of chips and wood dust are generated, which during disassembly can get into the internal parts of the Husqvarna chainsaw.

Removing the side cover and saw set

The side cover, or also called the saw chain brake cover, is held in place with two thirteen nuts.

After unscrewing the nuts, the cover is removed from the guide pins, after which you can remove the bar and chain from the chainsaw. Some models of Husqvarna saws have a special mechanism installed that allows you to dismantle the cover and saw set without the help of special tools.

Starter

The starter is located on the right side of the Husqvarna and is held in place by several screws. By unscrewing them, you can easily remove the starter and thereby gain access to the flywheel and ignition coil.

Removing the flywheel and clutch

In order to unscrew the flywheel nut, you need to unscrew the spark plug and install a piston stopper in its place.

If you don’t have a special stopper, you can use an old cord from a chainsaw starter instead. It is necessary to tie knots on the lace at a distance of 2-3 cm, then, using a screwdriver, insert it through the spark plug hole inside the cylinder. The cord will limit the stroke of the piston, thereby preventing the crankshaft from turning and protecting the piston from damage.

Once the piston stopper is installed in the cylinder, the flywheel nut can be loosened. After the nut is unscrewed, it is necessary to use a hammer and a drift made of soft material to apply one sharp blow, installing the drift on the flywheel mounting shaft. This is necessary to remove the flywheel from the shaft, since the design provides for the installation and tightening of this element with great force.

You can learn more about how to properly remove the flywheel from a Husqvarna chainsaw, as well as how to completely disassemble the saw by watching the video. The wizard explains the entire process step by step and demonstrates all the necessary tools:

In order to unscrew the clutch you will need a special key. If there is no key, then it can be made from an old twenty-two head, grinding it in a certain way using emery.

The clutch has a left-hand thread and rotates clockwise.

Do not try to unscrew the clutch with a hammer and chisel, as some craftsmen advise. Using these tools, you risk breaking the clutch housing and increasing repair costs. It can also damage the crankshaft bearings.

Front handle

Removing the Husqvarna front handle is quite simple, as it is attached to the shock absorbers with screws.

Air filter and carburetor

To remove the carburetor, it is necessary to disconnect the fuel hose and damper rods from it; this can be done conveniently after the air filter is removed, which is installed immediately behind the carburetor and held in place with two 10mm nuts. After the air filter is removed, the fuel hose and the rods are disconnected, just pull the carburetor towards you and remove it from the studs.

Use tweezers and medical clamps to remove the carburetor.

Oil pump

On Husqvarna, the oil pump is installed on the right side of the chainsaw. It can only be removed after the clutch has been released. Removal does not require a special tool, because... The fastening screws are made for a regular Phillips screwdriver. After the screws are unscrewed, it is necessary to lift the pump and disconnect the oil hoses from it.

Engine

To remove the engine on a Husqvarna chainsaw, after the carburetor, clutch, flywheel and muffler have been removed, you will need to unscrew the four screws securing it to the body.

After the engine is removed, you can unscrew the ignition coil from it, remembering to first disconnect the wires leading from it to the ignition switch. The coil can also be removed immediately after the starter is removed.

Assembling the Husqvarna chainsaw should be carried out in the reverse order, and the flywheel nut and clutch must be tightened with the force specified in the chainsaw operating instructions.

Classic layout

The classic Husqvarna layout makes it easy to repair your chainsaw yourself. The set with the saw chain is located on the right and side of the saw, and the emergency brake is also located there. The engine housing is covered from left to right by an auxiliary handle. The on/off button is located at the back and is oriented under the thumb, while the accelerator key is pressed on the handle.

The drum and starter handle are located on the left, above the cooling grille. Bottom left is the fuel tank cap.

All elements of the mechanism are hidden under the case cover.

How and when to adjust the ignition on a Husqvarna saw

Users of Husqvarna chainsaws often have a question: how and when to adjust the ignition. The answer is simple. Husqvarna chainsaws have an electronic ignition coil and flywheel, which do not provide for adjustment. The only thing that can be adjusted is the gap between the coil and the flywheel.

To adjust the gap at home, you need to cut a feeler gauge out of a plastic bottle, and then loosen the screws securing the coil. Next, the probe is installed between the coil contacts and the flywheel. The screws are tightened.

It is necessary to adjust the gap during maintenance or when scoring is detected on the surface of the flywheel. Such scuffs indicate that there is no gap at all.

If, after adjusting the gap between the coil and the flywheel, the parts continue to touch, then it is necessary to check the crankshaft bearings for wear. They may be very worn and require replacement.

Basic malfunctions and ways to eliminate them

When starting to repair a chainsaw, you need to have an idea of ​​what malfunctions it may have, as well as how these malfunctions are eliminated. So, let's look at the signs of malfunctions and how to fix them.

Husqvarna chainsaw does not start

If the Husqvarna does not start, the first thing you need to make sure is that you follow the algorithm for starting the saw, as well as the presence of fuel in the tank. Detailed instructions on how to start a cold chainsaw and refuel it are available in the saw manual that comes with all Husqvarna chainsaws.

If you do everything correctly, but the saw does not respond, the reason may be a malfunction of the ignition system or lack of fuel supply.

To more accurately determine the reasons for this behavior of the chainsaw, it is necessary to inspect the spark plug, and then check it for the presence of a spark.

If the spark plug is wet and no spark is detected when checking, you should try replacing the spark plug itself. The replacement did not produce results, which means the problem may be hidden in the ignition coil, which is quite difficult to check on your own.

You can check the serviceability of the coil by installing it on a previously working saw of a similar model or by replacing the part with a working one.

If there is a spark, but the spark plug is dry, there is a problem in the fuel system. To eliminate it, you need to carry out a full diagnosis. The fuel system consists of a carburetor and a fuel line. Without any specific experience, you can check the fuel line for ruptures, as well as the cleanliness of the fuel filter installed in the tank. It is better to entrust complete carburetor diagnostics and repairs to professionals.

If the saw starts, but poorly

The cause of difficulty starting the saw may be a malfunction or incorrect adjustment of the carburetor. If the carburetor overflows, the chainsaw will be easy to start when hot, but quite difficult when cold, especially after a long period of inactivity.

An indirect sign of an excessive amount of fuel mixture entering the cylinder when the chainsaw is operating is the exhaust. If a lot of white smoke is emitted when the chainsaw is running, it is worth checking the proportions of the fuel mixture and carburetor adjustments.

Chainsaw chain spins at idle speed

If the Husqvarna chain rotates at idle, then we can conclude that there is a malfunction in the clutch mechanism or the idle speed is not adjusted. To eliminate the malfunction, it is necessary to remove the saw chain brake cover and inspect the integrity of the clutch spring. Replace defective clutch.

If the clutch is working properly, to eliminate chain spinning, it is necessary to adjust the idle speed using the adjusting screw marked with the letter (T) or carry out a full carburetor adjustment.

Important: a possible reason for an independent increase in idle speed is the appearance of air leaks into the engine crankcase or carburetor, which can lead to serious damage to the CPG.

Why does the Husqvarna chainsaw stall when you press the gas?

If the saw stalls immediately after pressing the gas, it is necessary to inspect the spark plug, which will help more accurately diagnose the problem. A wet spark plug indicates a malfunction or incorrect adjustment of the carburetor; in this case, the situation can be corrected by carrying out a complete diagnosis, repair and adjustment of this unit. If repairs and adjustments do not help, you need to replace the carburetor with a new one.

Another reason why a Husqvarna may stall when you press the gas is a malfunction in the fuel system, or more precisely, difficulty in supplying fuel to the carburetor. It is necessary to check the cleanliness of the fuel filter, as well as the integrity of the fuel hoses.

During the process of assembling the chainsaw during its complete repair, you can pinch the fuel hose coming from the tank to the carburetor, which will limit or completely stop the fuel supply and make the saw impossible to operate.

Why is the chain on the Husqvarna chainsaw not lubricated?

If your chainsaw has completely stopped supplying saw chain lubrication, then you need to check the entire oil system.

There may be several reasons:

1. Oil pump malfunction;
2. Clogged filter element installed in the tank;
3. Oil tank breather malfunction;
4. Oil hose rupture;
5. Mismatches in the oil hole on the bar and on the saw body (if the supply stopped after installing a new saw bar);
6. Clogged oil channel in the saw body;
7. Clogged oil supply channel in the tire;
8. Oil pump drive gear malfunction.

Self-repair of Husqvarna chainsaws is only possible if you have at least some knowledge about the operation of a two-stroke engine, as well as the principles on which the chainsaw is designed. As practice shows, it is not difficult to disassemble a Husqvarna chainsaw; it is much more difficult to assemble it without aggravating its malfunction. Calculate your strengths in advance and do not hope that you will be able to repair the saw without some experience. In some cases, even experienced technicians put a lot of effort into correctly diagnosing the problem.

Why it won’t start and what to do

Among the malfunctions of the Husqvarna chainsaw are poor engine starting. The engine either cannot be started at all, or it starts poorly.

There is no clear answer to the question why the chainsaw won’t start. The main assembly unit of the tool is the engine. The following conditions affect the stability of operation:

• fuel mixing;
• air;
• presence of a spark;
• lubricant

Each factor is responsible for its own working unit:

• for the fuel mixture - carburetor;
• for air - a cleaning system, in particular an air filter;
• for the spark - the ignition mechanism and spark plug;
• lubrication - lubrication system and gasoline.

A common reason why chainsaws do not start is failure to follow the starting algorithm. The engine unit should only be started after all parts have been completely assembled:

• tires;
• saw chain;
• caps

The chain brake is always on. To avoid losing control of the instrument, you must not start in the air.

Starting the engine in a cold state is done as follows:

• Place the tool on the ground, step on the back handle with your right foot, and place your left hand on the front handle.
• The saw is in a stable state, the chain does not touch the ground.
• With your right hand, take the starter handle and pull the cord, but do not twist it around your hand.
• As soon as the first flash occurs, return the choke lever to its initial position, opening it, and repeat the start.
• They gas it and let it go. The blocking is disabled.
• The engine is switched to idle speed by quickly turning off the gas limiter.

Starting a warm engine is carried out in the same sequence, but without opening the damper.

If the start is made correctly, but the engine does not work, a possible reason is the lack of fuel in the tank, or the carburetor fuel chamber is not filled. Check the tank and chamber, fill them with the mixture.

If the ignition system malfunctions, inspect the spark plug and check for the presence of a spark at the electrodes. If it is wet (gasoline floods the spark plug) and a spark is not detected, the part is turned out, dried or replaced. If it is dry and there is a spark, then there is a problem in the fuel equipment - clogging, depressurization of the gas intake.

See » Review of semi-professional chainsaw Stihl MS 260-16

Magneto malfunctions are also confirmed by a weak spark. Despite the ignition operation, there may be no flash in the cylinder, while the spark plug removed from the cylinder is wet. The solution is to purge the cylinder with the carburetor flaps open.

The electrodes of the system are covered with soot or oily. This can be removed with a wire brush. The spark plug is washed and cleaned by allowing the gasoline to evaporate.

Violation of the gap between the side and central electrodes leads to a poor start. The normal interval is 0.6-0.7 mm. It is adjusted by hemming.

If the ceramic insulator surrounding the central spark plug or the current-carrying core of the wire is damaged, replace it.

If it starts and stalls

The Husqvarna chainsaw starts and stalls when you press the gas. This is caused by a clogged carburetor jet and a dirty fuel tank filter. The defect is eliminated as follows:

• disconnect the fuel hose from the carburetor;
• inspect the fluid leakage - the breather is clean if a full stream comes out.

The next reason why a chainsaw stalls is contamination of the muffler with exhaust resins. The issue can be resolved by cleaning.

Wear of piston rings affects the operation of the cylinder-piston group. If there is play during inspection, parts are replaced.

When starting the engine, the unit may also stall:

• as a result of water entering the mixture;
• due to poor chain lubrication;
• oil wire leakage;
• clogged channels.

Pay attention to the chain:

• if dryness increases, clean the oil supply channels, inspect the elements connecting the fittings to the tubes;
• If there is an oil leak at the connecting points or there are cracks in the tubes, they are sealed with sealant.

The engine does not develop speed:

• if the piston rings burn in the grooves;
• when the crankcase rubber seals wear out and lose elasticity;
• leaks in the connection between the cylinder and the crankcase;
• due to incorrect setting of the ignition timing;
• as a result of contamination of the cylinder fins and fan grille;
• under heavy load immediately after purchasing a new engine.

Adjusting the Husqvarna chainsaw

Modern chainsaws have a complex system and consist of several main components, which at times require maintenance and adjustment. In this article we will talk about how to adjust the carburetor on a Husqvarna chainsaw.

IMPORTANT. An experienced electrician leaked to the network the secret of how to pay half for electricity, a legal way. Read more

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

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

• high idle speed;
• strong smoke when operating the tool;
• Difficulty starting a cool or hot engine;
• lack of traction and low maximum speed.

This is by no means a complete list of problems that can be solved by tuning the Husqvarna carburetor. In a number of different cases, adjusting the properties and amount of fuel consistency is carried out after a half-year engine repair or during scheduled maintenance of the chainsaw.

The manufacturer Husqvarna AB recommends adjusting the carburetor before and after break-in.

The design and principle of operation of the Husqvarna carburetor

To successfully install the Husqvarna chainsaw carburetor option, you should know its structure and understand how it works. In fact, everything is not as difficult as it seems at first glance.

The saw carburetor has an integrated 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 allows the fuel supply to be dosed into 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 cool 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 in this case, when a cool start is carried out in normal mode.

Problems with the fuel supply system

If the tool does not work, this may be due to the fact that fuel is not entering the cylinder.

First of all, you need to check the fuel filter for contamination levels. To check this, you need to remove the fuel hose and check how quickly the fuel flows.

If it is supplied under low pressure, then the problem lies specifically in the filter.

Despite the availability of service centers for the maintenance and repair of gas-powered tools, many owners of chainsaws prefer to repair them themselves. When starting self-repair, you need to know what a chainsaw consists of, how to diagnose faults and have a set of tools that may be needed to carry out repairs.

In this article we will look at how to independently repair a Husqvarna chainsaw and what is needed for this.
