Husqvarna how to make a starter

Do.It.Yourself repair starter repair is absolutely realistic if the breakdown is insignificant. How to do this. You can always find from our detailed videos. But it is better if you learn how to treat the right a saw, and the repair will not expect it soon. Most often, malfunctions in the work of the starter arise due to the lack of sensation of the power that the operator attached to the saw plant, as well as the clogging of the starter casing. Typical breakdowns of the Chinese chainsaw, and any analogue mechanism, say a motorcycle where the starter is present. There is the appearance of cracks on the pulley or its breakdown, a torn cable or a cracked spring. Follow the behavior of the car in time, check it before and after the workflow, and then you will have to buy spare parts for chainsaws extremely rarely.

To repair the starter on the STIHL 180 saw, you need to carry out the following step.By.Step actions:

  • Unscrew the outer cover with an electric screwdriver or a special screwdriver.
  • We disassemble the components of the starter of the chain saw, namely. A sleeve, a starting spring, a lid, a handle, a cord, a reel, a deflector.
  • We consider each of them on the lack of cracks, defects, changes in color and structure.
  • Often the cord turns out to be torn or wound outside the reel launch. You need to independently wind it in place, scroll several times to launch or order a new one in our store. It happens that it breaks off at the place of fastening to the handle or starting coil.
  • The damaged pulley is a cracked, split or deformed part, which cannot work fully. We acquire a new one, and replace it in the place of the old.
  • The starting spring in most cases bursts without withstanding the load. Defects at the place of its fastening, the place of inserts and other problems are also very popular.

Upon completion of the repair of the system, you need to collect it in the correct order. Namely, the pulley is located above the launching spring, firmly adhered to it; It is wrapped in a cord, the edge of which is torn into the lid so that at the time of the start the pulley winds the cable inside. The required voltage can be achieved by making four turns. All the details of the procedure you can clarify for yourself in a detailed video.

The repair of the starter of Husqvarna is almost no different from similar operations performed with Stepil’s starter, but an important nuance here is compliance with the correspondence of the details to the chainsaw itself. That is, if you try a coil from a completely different saw, then this may entail unpleasant consequences in work. Another thing is if the store recommends a cheap analogue with which your saw will work for a long period. It is worth noting that to Khuskvarn 142 or Chetia 180, as the most popular consumer saws, you should not use home.Made elements, for example, a cord or other devices. Husqvarna Starter spring is one of the most commonly replaced details. This partly happens due to the fault of the operator, if he regularly applies beyond the effort to start the saw, and sometimes from the unreliability of the attachment of one of the edges of the spring. Similarly, it is necessary to replace the details with the Ural saw, unless, make a little more physical effort.

Battering Roll Daw Makita Duc302. Review

Each tool is bought for its own tasks, in this case, independence from the outlet for small work on the site was needed. Therefore, the choice fell on the battery saw. The gasoline analogue did not consider in principle due to inconvenience: the smell of gasoline, constant refueling, replacing candles, filter, noise (the electric engine also has it, but much quieter), the launch itself is directly. Here, in general, a gasoline tool needs to press a bunch of buttons and finally pull the starter. What you need to start the electric saw? Press the button. All. The difference in ease of use is simply colossal.

Electric saw is very light, in full collection weighs about 4.7 kg. Because of this weight, you can cut the branches, holding it with one hand.

2 batteries were bought separately for the saw, with a capacity of 4 ah. They brought firewood car to a neighbor, decided to conduct a test for the duration of work from one charge of batteries. Dry pine, the diameter of the trunk is 18-20 cm, 34 sawed 34.

If you plan to work with a saw for a long time, consider the highest capacity batteries for Makita for purchase. 6 ah. They weigh as much as 4 or 5 amerer, and the saw works from them much longer.

The speed of the chain is relatively low. Total 8.3 m/s. However, a gearbox is installed in the electric saw, which significantly increases the torque and allows you to saw hard wood of wood without stuck: for example, oak or ash.

The only drawback. Oil leak. But it is eliminated very simply by sealing a small hole in this tank.

Repair of the starting device

Dismantions of the starter for replacing the cord for an experienced user do not create problems, but the plastic case in most cases is not subject to repair. The Chinese chainsaw assortment for the most part is copies of the most popular European models, so we analyze the Chinese chainsaw according to the standard scheme.

Worn details of the saw headset are not restored.

  • At home, you can shorten a new chain for installation on a shorter tire.
  • The resource of branded components of tires is equal to the resources of three saw chains.
  • This indicator can be significantly reduced by the wrong choice of chain step or a large wear of the crown of the drive star.

Device and principle of operation

Almost all well.Known manufacturers of chainsaws complement their own products by starters of the identical principle of operation. After all, it is not for nothing that in any specialized store today you can find universal types of starters that are equally perfect for any chainsaw model, whether Makita, Husqvarna or Stihl, or even a semi.Official fake from China for the above brands. Nevertheless, among the starters of domestic manufacture there are those that have their own unique features. The Urals, forester, etc.P.

The work of the starter is as follows: there is a pen on the chainsaw housing through which a special cable passes, stretching and hooking the rattle of the ratchet mechanism with a sharp stretch. In this case, the movement is transmitted to the drum with slots on the shaft.

At this time, the crankshaft makes several full speed, as a result of which the working mixture is compressed between the cylinder head and the piston. If you release the pen, then the contact between the slots and the ratchet will be lost, as a result of which the shaft will simply stop!

The larger the volume of the chainsaw engine, the more fuel-air mixture is required for further ignition. Based on this, to launch high power, as a rule, more jerks are necessary for the starting cable. For greater convenience and to accelerate the return of the drum, manufacturers began to use baked return springs from elastic steels.

Simplification of the launch of the chainsaw is achieved at the expense of the following factors:

  • The presence in the design of some models of chainsaws (for example, in the models of Maxcut, Partner line S and T.P.) a special pump that guarantees timely pumping of the fuel mixture.
  • Installation of an additional spring that provides easier unwinding crankshaft when a cable is displaced.
  • Due to the preliminary enrichment of the mixture through the corresponding damper in the carburetor case.
  • Placement of an automatic decompression valve, which will reduce the working pressure inside the cylinder.

How to assemble a starter on a Husqvarna chainsaw

After a chainsaw appeared in the house, many owners sighed with relief. After all, this tool allows you to solve complex problems quite quickly and easy.

But, here it is worth considering that the chainsaw often fails. This is due to the fact that it is subjected to large loads during operation. Therefore, you must always be prepared to eliminate breakdowns.

Today there are a large number of workshops who offer their services for the repair of chainsaws and other tools. But, this does not mean that when a malfunction occurs, you need to immediately run to the repair workshop.

Some malfunctions can be eliminated with your own hands. To do this, you just need to know the main causes of breakdowns and the way to eliminate them.

So, in the process of frequent use of the tool, breakdowns can occur:

Each of these breakdowns can be eliminated with your own hands. The main thing is to know the sequence of work when eliminating a particular malfunction.

Device and principle of operation of the starter of the chainsaw

Most of the well.Known manufacturers of chainsaws equip their products with starters working on almost the same principle. Its essence is as follows: a pen is located in the groove of the saw case, through which the cord is missed. With a sharp raising of the handle, the cord is also stretched, which leads to the cloth the drum, which is in the ratchet mechanism. Through this, a drum with spitz, which is located on the shaft. During this, the crankshaft makes a couple of revolutions, which leads to the compression of the fuel mixture, which at that moment is between the cylinder head and the piston. When lowering the handle, on the contrary, the ratchet and spitz lose their contact, which leads to the stop of the shaft.

With an increase in the power of the chainsaw, the amount of fuel mixture increases, which when the chainsaw is launched should be ignited. In this case, to start the engine, it is necessary to increase the number of jerks of the starter cord. To accelerate the return of the drum mechanism, manufacturers use a special steel return spring of the starter, which has excellent elasticity. To facilitate the launch of the chainsaw, leading brands use other methods:

make, starter

  • Preliminary enrichment of the fuel mixture using a separate damper;
  • Installation of an automatic decompression valve, which provides a decrease in pressure inside the chainsaw cylinder;
  • Installation of a primer designed to pump fuel before starting the engine.

The use of one of these technologies greatly facilitates the launch and extends the life of the starter, which is especially clearly visible at low temperatures.

Why do you need to configure the Husqvarna carburetor

The carburetor is one of the important mechanical components that make up the chainsaw. In his tasks. Mix fuel with air and supply the resulting composition to the engine. But in the process of the chainsaws, situations arise when the Husqvarna carburetor adjustment becomes necessary. Depending on the reasons, the settings of the carburetor of the chainsaw 142 and other episodes are performed to prevent the following situations:

Since the carburetor affects the quality of the fuel, in the first case, the need for the settings of the carburetor of the saw 137 or other professional series, such as Huskvarna 240 or 260, involves the influence of a sufficient amount of combustible raw materials entering the carburetor to mix the mass of air. It is known that maximum performance is possible only with a certain ratio of these substances. The second point of adjustment of the gas.Rosopyle of the carburetor mixer is due to the lack of incoming air, which causes a lack of inhabited gasoline with its output in the form of dense smoke. Timely change in parameters with your own hands to reduce the amount of fuel injected significantly reduces the consumption of this product.

Repair itself will retain not only the budget, but also the time spent on transportation, and the line in the workshop. The same applies to the replacement of various spare parts in a gasoline tool, such as a chain on a chainsaw or a universal head of a trimmer for grass on a motor pump or oil for electric drives.

When you need to adjust the Husqvarna carburetor chainsaw

The neglect of deviations in the normal operation of the gasoline tool is fraught with the fact that even with a strong desire to adjust the Husqvarna chainsaw carburetor can be useless, and it will be necessary to replace either this unit or already engine components subject to prolonged thermal or mechanical loads. Therefore, as soon as the saw showed the first deviations, it is necessary to carry out immediate repairs in the form of simple corrective actions. Among such changes in the work, we note:

  • The chainsaw slows down too slowly;
  • The tool does not reach maximum power, and when loading it falls quickly;
  • The motor often stops;
  • During the work of a chain saw, a loud noise is heard;
  • A chainsaw frees a non.Characteristic amount of smoke, increasing at each stage of the load.

Husqvarna 142 chainsaw carburetor adjustment

Setting up the Husqvarna 142 chainsaw carburetor makes it possible to get rid of a number of problems.

  • Slow acceleration of the engine;
  • Inability to achieve maximum torque;
  • Frequent shutdown of the engine;
  • The appearance of loud knocks when working as a tool;
  • Increasing the number of fuel consumed.

If you do not set the saw carburetor in time, this will lead to more serious breakdowns, from which the engine and ignition system will suffer.

Repair of the starter Husqvarna and STIHL. Subtleties and features in work

Why not start and what to do

Among the malfunctions of the Husqvarna chainsaw, the engine is highlighted. The motor is either completely impossible to start, or it starts poorly.

When asked why the chainsaw is not started, there is no unequivocal answer. The main assembly unit of the tool is the engine. The stability of the work is influenced by the following conditions:

See also  Hacksaw for metal and wood differences

For each factor, his working knot is responsible:

  • For the combustible mixture. Carburetor;
  • For the air. The cleaning system, in particular, an air filter;
  • For a spark. Ignition and candle mechanism;
  • Lubricant. Lubricant and gasoline.

The common reason that the chainsaws are not starting is referring to the non.Compliance of the launch algorithm. The motor unit should be launched only after the full assembly of all parts:

The brake of the chain is always turned on. In order not to lose control of the tool, you can not start in the air.

The launch of the motor in the cold state is carried out as follows:

  • Put the tool on the ground, step on the back handle with the right foot, the left hand is located on the front handle.
  • The saw is in a stable state, the chain does not apply to the soil.
  • Take the starter handle with the right hand, pull the cord, while it is not twisted around the hand.
  • As soon as the first outbreak occurs, they return the lever of the air damper to the initial position, opening it, and repeat the start.
  • Gas and release. The lock is turned off.
  • They transfer the engine to idle speed due to the rapid shutdown of the gas limiter.

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

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

If the incendiary system is faulty, the candle is inspected and checked for the presence of spark on the electrodes. If it is wet (gasoline floods the candle), and the spark is not detected, the part is turned, dried or changed. If it is dry, the spark is present, then the problems in fuel equipment are clogging, depressurization of the gas intake.

Magneto malfunctions are also confirmed by a weak spark. Despite the ignition, there may be no outbreak in the cylinder, while a candle turned out of the cylinder, wet. The method of elimination is the purge of the cylinder with open carburetor shutters.

The electrodes of the system are covered with soot or oiled. This is eliminated using a metal brush. The candle is washed, cleaned, giving gas to evaporate.

Violation of the gap between the side and central electrodes leads to a poor start. Normal interval indicator-0.6-0.7 mm. It is adjusted by the bending method.

In case of damage to the ceramic insulator surrounding the central candle, or live cores of wires, the wires are replaced.

If it starts and stalls

Husqvarna chainsaw starts and stalls when you press the gas. This leads the jacket of the carburetor jacket and the contamination of the fuel tank filter. The defect is eliminated as follows:

The next reason why the chainsaws stall is pollution of the muffler with exhaust resins. The issue is solved by cleaning.

Distance of piston rings affects the work of the cylinder.Piston group. In the presence of a backlash during the audit, the details are replaced.

When starting the engine, the unit may also stall:

  • With increased dryness, the channels supplying oil are cleaned, the elements of the connection of the fittings with the tubes are examined;
  • When oil leaks in the connecting points or the presence of cracks on the tubes are sealed with sealant.
  • If the piston rings in the grooves are buried;
  • With the wear and elasticity of the rubber sealing of the crankcase;
  • Leakage of the cylinder connection to the carder;
  • Due to improper installation of the ignition force angle;
  • As a result of contamination of the ribs of the cylinder and the fan lattress;
  • With strong load immediately after buying a new engine.

STRACTION adjustment

The circuit brake often does not work due to clogging with lubrication or sawdust of the brake tape and space under the lid. All parts from blockages should be cleaned. Perhaps the tape simply worn out, then it must be replaced.

Some parts of the chainsaw wear out faster than the rest. These include the leading star, tire, chain, anti.Vibration elements. It is better to always have at hand for quick spare replacement at hand. Do not neglect the sharpening of the chain.

Repair of the starter of the chainsaw

With frequent launches of the chainsaws, some starter details are constantly subjected to dynamic loads. As a result, a cable may burst, several teeth of the ratchet chill, and the shaft will turn out at a much lower speed. Therefore, the audit and even the repair of the starter. Operations, sometimes carried out several times per season.

Replacement of the cord

When it is pulled, there is a constant friction of the cable about the starter case. For replacement, disassemble the hull of the node, and carefully lift the rattles in such a way as not to allow jumping from their nests of the return spring. It is better to do such work together: the assistant fixes the spring, while the cable is replaced. After fixing the cable in the handle and in the grooves of the drum, the cable is wound on the roller, and the case is assembled.
