Husqvarna 100 40 chainsaw. Features of operation of non.service

Husqvarna 100 40 chainsaw is used for work in the garden in a summer cottage, as oil is an amazing option, as for rolling trees, so for harvesting firewood. Husqvarna 100 40 chainsaw has technical properties that determine the highest performance not security. Motor revolutions achieve nine thousand units per minute. Cylinder size with a face value of 40.4 cm³. Fuel tank tank with a volume of four hundred 10 ml, and a tank for oil. two hundred ml. It is worth considering that the noise level is 100 eighteen dB. The mass of the unit is 4.6 kilograms. Tire length from 30 three to 30 eight cm, chain step. 0.83 centimeters.

The advantages of the model

  • Relatively small weight of the Husqvarna 100 40, two non.ergonomic design in SOVOUKU with the front handle of curved shape make the operation of the equipment very comfortable.
  • Anti.vibrational system allows you not to feel lethargy a long time.
  • The presence of a non.chain brake shield is foreseen to ensure the safety of users.
  • Husqvarna 100 40 chainsaw power is increased by a forged cranked shaft consisting of 3 sections.

Possible malfunctions of the chainsaw Husqvarna 142

As well as any other devices, the operation of which is associated with saturated loads with non.complex criteria, the Husqvarna 100 40 chainsaw is two 40 is two, immediately the prerequisites for the problems are naturally conditionally divided into two groups:

  • Motor breakdown as it is also called the piston group. Tasks with fuel, exhaust or ignition system.
  • Problems that arose in mechanical nodes. the bus, the clutch system, the brake as it is also called the lubricant.

Engine

Motor breakdown is one of the frequently found non.laborious. This problem is manifested by such factors:

Not starting or badly starting up a chainsaw.Reason and how to eliminate.

Why the chainsaw is not started.Cause.How to eliminate.

  • Unstable work at idle.
  • Does not start.
  • There is not enough power, or Husqvarna chainsaws one hundred forty.two starts and stalls, as soon as it starts to gain momentum.

Before starting the repair of the Husqvarna 142 chainsaw, it is recommended to carry out full diagnostics of equipment to accurately determine the causes of problems.

The reason why not A chainsaw is started Husqvarna 142

If the Husqvarna 142 chainsaw is not started, there may be several reasons. Of the most common, the following can be distinguished:

  • Damage to candles. to understand whether the candle is good, you need to unscrew it and conduct an inspection. In the event that the insulator from Faor has cracked, you see a burned or damaged electrode, you should immediately replace the candle. In addition, having worked for several seasons, Husqvarna chainsaws one hundred forty.two requires examination of spare parts. Candles also produce their resource, and to protect the saw, change them to new.
  • Blockage of the carburetor. in the process of work, gradually, fuel evaporation settles on the inner walls, forming a sticky consistency that can clog the carburetor, preventing the engine starts by the engine. You need to clean it with a special detergent. Repairing the Husqvarna 142 chainsaw, the carburetor adjustment is always carried out with a warmed engine and cleaned systems.
  • The ignition coil failure. before you decide to replace this part, make sure that the candles correspond to the required technical condition.

How to adjust the carburetor of the chainsaw Husqvarna 142

Setting the carburetor of the chainsaw Husqvarna one hundred forty.two should be carried out with a heated engine. Pay attention to the condition of the air filter, which, if necessary, will need to clean and make sure that it is not clogged. Husqvarna chainsaw carburetor adjustment is performed by forty.two with your own hands using three screws:

Turning clockwise the control screws of low and high revolutions, translate them to the limit, and after the peak is reached, scroll them in the opposite direction, one and a half turnover. Babble starts and stalls, the chainsaw of Husqvarna 142 Piston videos. When working at idle, a chain for the chainsaw of Husqvarna one hundred and two should be motionless. Check at maximum speeds.

Avoid most malfunctions and expensive repairs, you can observe the instructions and recommendations of the manufacturer, as well as using original spare parts for the Husqvarna 142 chainsaw.

The installation system device

A key role in any chainsaw is played by a carburetor power unit of a two.stroke type. Its power directly depends on the selected model and purpose. The second important mechanical node in the device is considered the saw part, which consists of a tire, a cutting chain and a chain wheel. Data parameters of the components may vary.

With lubricating mixing, it is carried out using special oil, which is poured into a specialized tank, it is located on a manual block. Separately, it should be distinguished that the volumes of the oil tank and fuel are calculated in such a way that their contents, as a rule, ends at the same time.

Fault options and elimination methods

Regardless of the brand of the chainsaw. Champion, Husqvarna 236 or Patriot, the reasons for poor work are identical. Options why the stihl chainsaw is not started, the mass is the following.

The chainsaw is poorly started on the cold

If the saw is poorly started on the cold, it means that it does not have compression. This is due to abrasion of rings due to long-term operation. It turns out when the user is trying to start Champion 137 in a cold state, compression for this manipulation will not be enough.

In this case, it is not recommended to systematically pull the handle. In the end, the unit will nevertheless start, but at the same time, other mechanical nodes may break off it. In this situation, you need to replace the erased rings with new.

The chainsaw is not started on hot

Here the reasons lies in the filing of the engine and get wet of the candles. Here’s what to do in such a situation:

  • rearrange the air damper in the middle position;
  • well make the components of the parts;
  • start the device for 10 seconds;
  • transfer into the mode of operation at idle;
  • on a chainsaw caliber or other model completely open the damper.

Next, just start the motor at idle with pulling the handle. If the engine does not overheat, it will easily start.

In the event that this option of eliminating the malfunction did not help, then the motor has already managed to cool strongly. Make a fiction of half.gas according to the recommendations from the instructions and repeat the operation.

You should also try to scroll through the cold screw in the direction of movement of the clockwise. The higher the speed of the rotation in the equipment, the easier it is to start it. You should know that the chain at idle should remain in a stationary position.

The chainsaw is poorly started and stall immediately

In this situation, the reason is the filling of suppositories with gasoline at the moment when the user tried to turn on the unit. A small volume of fuel accumulates under the candle electrodes, which is why there is no spark in the equipment.

Removing a candle and its thorough drying will help to solve the problem. In addition to these actions, you can additionally fragment. But this manipulation should be carried out exclusively using a gas burner. In another case, a small cargo in the field of electrodes may form. After complete drying of the candles, you need to drain the excess fuel and leave to dry the equipment itself.

Chinese saw does not start

It should be noted right away that Chinese devices do not have a distinctive features from other analogues. They are also reliable and productive, moreover, they cost less. The only thing that is necessary for this device is necessary is to use only branded oil and fuel.

Most units do not work well on the fuel of domestic manufacturers, gasoline clogs channels and, as a result, fuel does not enter the motor. Use fuel either of high quality or from the manufacturer of the saw itself.

Why is the new saw not working

New equipment should not have problems with the wear of functioning mechanical parts, since the model came out only from the conveyor. Such untidiness may occur in the case of the acquisition of demonstration technology, which was more than once used to advertise the company. The cause may also be improper operation of the unit, which does not comply with the recommendations from the instructions.

First of all, you should check whether all parts and components of the elements are installed in their places. Still, for example, Husqvarna will not start if the fuel mixture prepared without taking into account the necessary proportions was poured into it.

But if all the recommendations are followed, each part is carefully recorded in its place and the equipment was not purchased from the stand, probably the buyer came across a defective device.

The tank is not enough fuel or it is of low quality

This is one of the most common reasons. Users of gasoline technology, in order to save, often use budget fuel. At first, the unit will regularly perform its work, but the problem will certainly arise after several months of operation.

It should also be remembered that fuel has a shelf life, it should not be stored in the tank for more than three weeks. Such liquid with constant contact with oxygen quickly loses the octane number. This makes gasoline completely unsuitable for use.

Problems with filters

Polluted filters are one of the main factors of the “non.launch” of the chainsaw. Check the air filter for cleanliness, it is located under the clutch body. The fuel cleaner is located directly in the fuel tank.

The location of the air filter and the spark plug

In addition to everything, you should examine the bars in the gas tank. For diagnostics, you should remove all the clogged parts for a while, start the device without them.

How to “run” a chainsaw correctly

In order for the new equipment to work normally, it is necessary to run it correctly.

  • First you need to prepare a fuel mixture, the proportions of which depend on the power:

How a two.stroke engine works: briefly, but it is important to know for a clear launch of a lawn mower

Lawn mowers are produced with two.stroke or four.stroke internal combustion engines. The difference in the design is significant, but each model starts on the general principle. I show on the example of the Chinese trimmer for Eco grass.

The engine is called two.stroke because the full.time cycle is two tacts: the stroke of the piston from the upper dead point of the VMT to the lower NMT. In this case, the launch occurs with the second achievement of the upper position.

Similarly, chainsaws, boat engines and gasoline tools of another similar technique work. Consider the procedure. We are supposed to figure it out.

To start a trimmer motor for grass, we pull the starter’s cord. Its stretching is spinning a crankshaft with a flywheel creating the moment of inertia. The rotation of the crankshaft shaft is converted into the reciprocating movement of the piston.

The two.stroke motor has 4 working cycles:

  • The first movement of the piston from the VMT to the NMT is accompanied by the injection of the fuel mixture (gasoline with butter and air), when the carburetor inlet valve opens under the influence of the created vacuum;
  • The movement of the piston from NMT to the VMT: the intake and exhaust valves are closed, and the working mixture is compressed in a sealed volume;
  • Both valves remain closed. At the upper dead point of the piston through the contacts, the spark slides through the contacts.There is an explosion of compressed gases. Its strength with an impulse throws the piston down and rotates the crankshaft through the connecting rod;
  • The force of inertia of the flywheel directs the piston from the NMT up: the exhaust valve opens and through it the combustion products are pushed into the exhaust pipe.

All stages are performed automatically, but they are prepared by a person with his actions. When making errors it is made, the benzotrimer does not start and may break.

I try to make out all these points in more detail.

Cycle: what mistakes of beginners lead to breakdown of the engine of the trimmer for grass and exclude its normal operation

6 common mistakes with fuel

The manufacturer in the instructions clearly indicates the brand of gasoline with an octane number, oil and their proportions.

The first three errors are that the user of motorcycles violates all or one of these requirements. The motor will most likely start and work, but its resource may decrease sharply.

A small amount of oil, like its absence, will lead to the fact that the walls of the cylinder will not grease normally, and the piston rings will scratch them, and not slide.

Excess oil will simply burn, forming soot. She will pollute everything, including the piston and cylinder.

Failure gets into the valve, blocks their work, after which the motor will not start.

Will have to disassemble and clean the carburetor, or even put a new. Of course, you can try to wash the piston and the cylinder: it may be possible to bring them into working condition, but it is better not to bring them to.

The fuel mixture must be prepared with high quality and in strict proportion. The repair of a spoiled engine is expensive, about 70% of the price for a new gasoline trimmer for grass.

For the preparation of high.quality fuel mixture, I have a special container with a factory division of divisions in a set of trimmer for grass. Gasoline is neatly poured into it to the level of 500 ml, and then the oil to the required label.

An alternative method is the preparation of a fuel mixture with filling gasoline into a calibrated container, for example, a liter canister or a plastic bottle to a label, and an oil additive with a medical syringe according to its divisions.

The dosage with a syringe is more convenient, is considered the most popular way.

I recommend filling gasoline through a funnel with a narrow neck that has a filter: a metal mesh. protection against small garbage.

The prepared mixture should be well shaken and mixed until a uniform color appears. Only after that it can be poured into the tank.

If the mixture does not blame, then it will remain in the tank, and through the carburetor will enter the combustion chamber in portions with different ratios of gasoline and oil.

Fractions of clots of oil clog a candle. The motor stops, stalls, does not start. This is the fourth mistake of beginners.

It should be borne in mind that gasoline is hazardous. The risk of fire exists. Therefore, it is necessary to fill the mixture at a safe distance from the buildings, and in the case of the strait, which often happens to eliminate the causes of a possible fire. Violation of fire fighting measures. error

After pouring the fuel into the gas tank, the latter closes with a screw plug and the lack of leaks is checked. The trimmer for the grass is raised up so that the gasoline fills the cork. There should be no subterations from under the lid or from the fuel hoses.

Lack of such a check. an error can cause a fire.

There is one technical cunning that can cause a benzotrimer motor is not started due to the cessation of fuel supply. If you look carefully at the center of the traffic jam, then a round hole is clearly visible.

We turned Motokosa. Gasoline filled the cork, but does not flow through the hole: there is a sapphone inside. He is working.

On the inside, its design is clearly visible: a valve system of plastic and rubber is built.

In the usual state, the valve is pressed to the hole and the fuel does not flow. Когда бензомотор работает, то топливная смесь расходуется через карбюратор. A vacuum is created in the tank. The vacuum opens the valve of the saapon, the pressure is restored.

You should know the two consequences of a malfunction of the sapuna:

  • Constantly open hole. fuel pours out of the tank during its inclinations (excess consumption and the probability of fire).
  • Contamination or sticking of the valve channel is the reason that the lawn mower does not start or stalls.

Check the soundtress is easy: you need to blow it in both directions.

All about the gas tank cover, including the repair of the saapun, is shown in the video of Bogdan Shabanov.

3 additional advice associated with limited chemical resistance of a mixture of gasoline with oil:

  • Do not create an excessive fuel supply. Use freshly prepared fuel mixture. In a maximum of a couple of weeks, she will lose her useful qualities;
  • Prepare as much fuel as it will go to one mowing during the day. At the end of the work, drain the rest from the gas tank and burn the last drops from the fuel canal with a neglected engine;
  • It is especially dangerous to leave the mixture in the gas tank for a long time. winter. In the spring, you will make sure that the engine does not start without cleaning the carburetor (gasoline evaporated, the oil thickened and glued the valve).

In more detail, the technology for eliminating these malfunctions shows in its video video “Chinese lawn mower is not started” Sergey Lesnik. Pay attention to the fuel filter.

To adjust the work of the carburetor allows a special screw, but it is not worth it to twist it without need: the factory adjustment is accurately exhibited. It is better for novice users to contact the service center.

How to make sure that there really is no spark

To make sure there is a spark on a chainsaw, you need to perform a simple procedure:

  • The top cover of the case is removed.
  • Carefully, with a rosette below, so as not to tear the wire of the candle, the cap is removed from the candle.
  • Using a 19 mm end key included in the kit, the spark plug is unscrewed counterclockwise.
  • The cap is put on a candle.
  • The spark plugs wire or nut is closed to the mass, that is, pressed to the metal head of the cylinder block. To ensure reliable contact, the spark plug is pressed to the cylinder by electric pliers, a screwdriver with insulated handles or a hand in dielectric gloves. Do not do it with your bare hands. If the cap is broken, you can get a painful shock from the discharge of high voltage (up to 40,000 V at a weak current up to 80 mA).

Put the saw on the ground, press it with your foot to the ground and slightly pull it over the starter cord. At this stage, let’s see if there is a spark or not.

What is a sapun and how it affects the causes of the impossibility of starting a chainsaw

Few saws know about the existence of an element such as a ventilation hole on a chainsaw. This is one of the important parts of the tool that is responsible for balancing pressure in the fuel tank.

The principle of operation of the deflector on the chainsaw is that with a decrease in the amount of fuel in the tank, a vacuum or vacuum occurs. The smaller the fuel in the tank, the higher the pressure that becomes an obstacle to the fuel in the carburetor. To reduce pressure in the tank, a valve is used, which is a valve that allows air to pass in one direction.

If the ventilation hole is clogged, the air does not get into the tank, which means that the pressure begins to grow. On the cover of the tank of the chainsaw there is a sapun (depending on the model), and if the two.stroke tool of the tool does not start, it is necessary to check the operation of the saapon. Moving in the deflector malfunction is quite simple:

  • Unscrew the lid of the fuel tank. If the air flows, this indirectly indicates a malfunction of the pressure regulator
  • Twist the tank cover again, then try to restart the engine. If the engine starts, but after a while dies, it is necessary to clean the saepun
  • Another way to check whether the saapun is working is to disconnect the fuel line from the carburetor. If the fuel occurs periodically, the device works fine. If the dripping is weak and intermittent, it is necessary to clean the ventilation hole of the chainsaw to run the engine

Sapun (fuel tank cover valve) is cleaned with a pin. If the ventilation hole is highly clogged, the filtering element must be removed and cleaned. On different models of chainsaws, the deflector position is different (on most models it is in the gas tank cover). The video below shows the process of cleaning the ventilation opening using the example of the chausopila Husqvarna.

By putting a finger to the candle hole and pulling the starter, you can check the compression in the cylinder

If you feel that the finger is very drawn into the spark plug, then everything is in order with pressing. The absence of a vacuum in the cell indicates a malfunction. The piston cylinder node requires a more detailed examination, which will give an idea of ​​the state of the piston and cylinder, piston rings and bearings.

Basil may not be launched in a cold state due to insufficient compression in the crankcase. The main reason for this is damage to the gasket located between the cylinder and the engine card. Detecting the lack of compression is quite simple:

  • Pour gasoline into a regular cork;
  • We dip the removed hose into the fuel;
  • Disconnect the upper pipe from the carburetor;
  • Twist the throttle several times.

If when the chainsaw is launched, fuel is sucked out of the lid, then everything is in order with compression. If not, see the gasket.

If fuel is absorbed, then everything is in order. the gasket is the whole. Otherwise, you will need to purchase a repair kit and replace it. How to do this, look at the video why the Chinese chainsaw is not started:

When your chainsaw does not start, although you do everything right. it causes bewilderment.

However, do not rush to carry her for repairs. the reason may not be so serious and it is possible that you will fully cope with the alleged malfunction with your own hands.

It is difficult to find a solution why the chainsaws are difficult to start hot, you can in the instructions.

If you do not have it for some reason, then we will talk about the device of the device and possible problems in the first part.

If you do everything correctly, according to the instructions, but the chainsaws still do not start or stall, then the second section will help you, where you will learn about the most common solutions of this problem.

The most popular and frequently used users models of chainsaws are Ural, Husqvarna, Stihl 180 and Partner.

Although they have their own characteristics, they are generally similar, therefore, we will in general we will describe the possible causes of breakdowns and ways to eliminate them for all tools.

Diagnostics

Granta 8 valve causes

The situation when the malfunction makes itself felt, and the saw stops working, often puts the owner in a difficult position. In a good way, the unit needs to be repaired in order to find out exactly why it will not start, and then entrust the repair to professionals. However, not all breakdowns are fatal, and even the person who is far from technology can cope with them.

The first thing to do is to diagnose the device. It consists in a careful examination of the main parts of the saw, namely:

Bad reviews about Husqvarna 128r

The owner of the summer cottage can not do without a lawn mower or a trimmer for grass. But in the process of its operation, situations may arise when this unit for some reason stops starting up. And there can be many reasons for this. Let’s find out why the gasoline trimmer for grass does not start.

Why is a trimmer not starting for grass. the reasons

To determine why the gasoline trimmer for grass is poorly started or stalls constantly, it is necessary to sequentially check the operation of all the main units of the unit. It is especially important to do this after a long.term storage of a lawn mower. So, the main reasons for such a trimmer’s behavior for the grass are as follows:

  • The culprit that the lawn mower is not started, there may be a poor-quality oil-Benzine fuel mixture. It must be prepared strictly according to the instructions. The savings here are not at all appropriate, since it can lead to the failure of the entire piston group of a trimmer for grass. Do not cook too much fuel mixture, as excess gasoline will lose their qualities over time.
  • You should know that gasoline trimmers for grass of stamps such as STIHL, Husgvarna and some others do not start if they are filled with cheap gasoline with a small octane number. Therefore, for such units, it is necessary to use only high.quality high.octane fuel.
  • If the trimmer for the grass stalls immediately during the start, then perhaps he has a candle flooded. In this case, it is necessary to twist it and dry it well for half an hour. Then drain the excess fuel that is in the chamber, clean the candle from the carbon fiber, put it in place and try to start the lawn mower.
  • If your new gasoline trimmer for grass does not start, there may be a lack of a spark. And this happens because the nest, where the candle is located, is dry and fuel does not light up. Should be slightly moisturized with a few drops of gasoline threaded connection of the candle.
  • A gasoline trimmer for grass can stall due to clogging of air or fuel filters. It is best to replace such elements with new.
  • The graduation canal and sapun can also clog. Cleaning these elements of the trimmer for the grass, it will be possible to start the unit without any problems.
  • Another reason why the gasoline trimmer does not start for grass, even when there is a spark, there may be a clogging of a carburetor. To clean the channels and nozzles, it is necessary to blow them with compressed air using a compressor.

Wet candle of chainsaws: why and what to do

You can use to clean the carburetor and special washing.

Immediately after buying a trimmer for grass for grass, we are faced with a lot of questions. how to use it correctly, how to refuel it (if we are talking about a gasoline tool) and, of course, which fishing line for a trimmer is best chosen. Look for the answer to the last question in the article.

How to quickly remove the stump without uprooting?

Many gardeners will sooner or later face the need to cut down trees growing on the site. After that, stumps remain, and if the trees were significant, it is very problematic to uproot them. The article tells about alternative ways to get rid of stumps.

How to choose a gasoline trimmer for grass for grass?

Beautiful well.groomed lawn. decoration of any site. And regular haircut helps to preserve its attractiveness. This case cannot do without a lawn mower or a trimmer for grass. In the article let’s talk about the intricacies of choosing a gasoline trimmer for grass.

What needs to be done if a candle of a chainsaw was flooded?

Most often, this occurs in beginners when, at the first launch, “cotton” is passed on a closed air damper and continue to pull the starter handle, respectively, gasoline in the combustion chamber is obtained a lot, and not enough air does not allow gasoline to ignite.

  • Unscrew the candle with a candle key and check its condition. If the candle is wet and there is a spark, then it was flooded. Open the air damper, turn on the switch button, squeeze the gas “until it stops” and start. Excess gasoline should get out of the exhaust saw and the saw will start.
  • Unscrew the candle with a candle key and check its condition. If the candle is wet and there is a spark, then it was flooded. Turn the chainsaw with the opening of the candle down and take the starter ten times, while excess fuel will flow out of the engine cylinder. Then wipe the dry dry (replace) a candle, or replace with a new one and repeat the engine factory attempt to follow the operating instructions. If the candle is absolutely dry, then this means that fuel does not enter the engine. And since it is in the tank, it is likely to the problem in the carburetor. You can get a little mixture into the syringe, injected into the cylinder, tighten the candle and try to start the engine. But if the engine started up and immediately stalled, therefore the problem remains and you need to contact the service center.

The gasoline trimmer for grass does not start. the reasons

Many garden tools are useful and effective, but there are times when the equipment refuses to work. Among them, both a trimmer for grass, which can be dug up, both a miniature lawn and huge lawns.

Reasons why the gasoline trimmer is not started for grass

There are different reasons why the gasoline trimmer for the grass does not start:

    The most common breakdown occasion lies in the wrong choice of fuel. Often, overly economical users of the device pour something doubtful into the tank, but not fuel with a normal octane number. Low.quality fuel, which was kept in a plastic canister for a long time, has a terrifying effect. The device that has lost performance for this reason is sent to the full bulkhead of the mechanism.

The lawn mower is not started: the reasons and methods of elimination

Useful information for those who do not have a trimmer for grass after winter

Why does a trimmer not start for the grass after wintering? What are the main reasons for this problem?

Benzotrimmer may not start due to the fact that the fuel remained in the tank last year, which, simply put, was exhausted. Two signs may indicate this: the candle is dry and there is a spark. To eliminate this problem, you just need to replace the fuel.

In addition, a gasoline trimmer for grass after winter starts a little differently. Open the damper and pump up a little gasoline into the carburetor, and then take the handle until you feel some resistance. After that, you can launch.

With a long simple, an air filter can clog. Evidence of it may be the launch of “hot”, after which the trimmer for the grass immediately stalls. Perhaps in the cold season the filter managed to clog with dust. Two options are possible here: first you need to clean it, and if this does not help, then you need to purchase a new filter.

In general, a similar conversation should begin with the fact that after the purchase of a garden benchmain tool it would be better to get to know the instructions attached to it initially. Then many problems could have been avoided. But since this happened a gasoline trimmer for the grass does not start, you need to look for sources of inoperability. And in this article we will consider the main reasons why the trimmer for the grass is not started by the example of the Elitech T750 model, as well as tell the general recommendations for such a tool.

Start with banal! We will figure out how to properly start a gasoline trimmer for grass. Maybe such that the reason lies here.

First you need to bring a red toggle switch on a trimmer bar for grass to position “i”. This means the inclusion of power supply. Then you need to switch the fuel supply lever on the carburetor and use the fuel “suction” button (looks like a pipette, is on a carburetor). This is necessary to supply gasoline to the engine. Fuel supply lever to return to its original position. At the end, sharply pull the starter handle on yourself. The trimmer for the grass should earn. Try it several times if the first time does not work. If after such manipulations the situation has not changed and a gasoline trimmer for grass does not start, then it is worth it to inspect it on your own first before you lead to the service center. There are two main reasons why the garden trimmer is not started:

The second reason why the garden tool does not work is the fuel ended. On Elinech T750, a fuel tank is located near the motor, but on most trimmers it is there. We unscrew the cap from the tank and pour gasoline there (the most optimal version of the AI-92, it is inexpensive and does not clog the carburetor as AI-76). Do not forget to add special oil for engines to the tank, 50 grams on the gas tank is enough, without it the motor will begin to “sneeze” and quickly become unusable. After cover the tank with a cap, wipe the surface of a trimmer for grass with a dry rag and our hands. We also make the above manipulations to include a garden tool.

If the gasoline trimmer for the grass does not start as before, then it makes sense to give it to repair. And the reason for such a solution is simple. if you do not have appropriate skills, the repair of equipment is practically impossible.

In order for the tool to serve as long as possible and do not arise such malfunctions, you should first get acquainted with the instructions for the operation of a trimmer for grass

Also, pay special attention to the engine time for the grass for the grass. make a short break every 15 minutes of work and, finally, take care of the tool correctly, wipe it after work, lubricate with graphite lubricant. Observing such simple rules, you can significantly increase the life of the tool and it is quite possible that you will not have to look for the reasons why the gasoline trimmer is not started for grass.

Why is a trimmer not starting for grass gasoline? Prerequisites and their elimination

In the near future, the gasoline trimmer for the grass got the status of the 1st of the main tools in the arsenal of summer residents. And this is logical, because a motorized braid for grass allows you to quickly put a personal plot in order. But from time to time it happens that a trimmer for grass does not start hot and even cool. In such situations, it is necessary without the help of others to establish the cause of the malfunction. Let’s find out what to do if a trimmer does not start for grass. The prerequisites, which more often lead to such troubles, will be considered further.

Tips

It is necessary to regularly check for pollution and change the fuel filter in the fuel tank of a trimmer for grass (lawn mower) in time. The fuel filter for its replacement can be easily removed from the tank using a wire hook. The fuel filter is easily clogged with bottom precipitation in the fuel tank, which leads to a deterioration or stopping the fuel supply from the tank to the carburetor of a gasoline trimmer for grass.

For refueling a trimmer for grass, it is not necessary to use ethanol gasoline, since in small two- and four-stroke engines that are not used every day or at least every other day, this is a big problem. Ethanol from gasoline precipitates and turns into resin or varnish, clogging microscopic jacks and carburetor channels.

To maintain a carburetor in purity and good technical condition, you can buy a special additive for fuel for two.stroke engines, which cleanses the carburetor of tarry deposits. The additive price is relatively small and it (additive) is not dangerous.

What to do if nothing helped?

Why the moped does not start: the three main reasons and the verification methodology

If the chainsaws are still not starting, and the causes and methods of elimination could not be identified, then this is an occasion for a visit to the service center. But if it is not nearby, then you can try to perform a number of other actions, all this is at your own peril and risk.

Sometimes the only way out is to seek help from the service center

What other causes of malfunctions can be:

  • Low compression degree in cylinders. if the compression rings are worn out or deformed, then an overly large gap between them and the walls of the cylinders. Because of this, the fuel mixture does not burn, but seep out out.
  • The carburetor is not tuned. it is difficult to establish a device for an amateur, but it’s worth a try.
  • Mechanical malfunctions. if extraneous sounds were heard before the break: rattle, clang, ringing, then probably the inside of the engine are destroyed. Without experience in the overhaul of two-stroke engines, something will be extremely difficult to do something.

Compression is measured using the device of the same name (compressometer). It is screwed up instead of a spark plug, after which you need to try to “get” the motor. The indication that will appear on the dial will be the value of the actual compression. The nominal value will have to be found in the documentation for the engine.

The finger should be drawn quite tightly, this means that with compression more or less normally. If there is no discharge, you have to carry out overhaul.

Another problem may be a damaged gasket between the motor card and the cylinder. This is clarified by the experimental way. Need:

  • Remove the pipe from the carburetor (from above).
  • Pour fuel into a cork.
  • Take a pipe removed earlier in poured gasoline.
  • Twist the motor and observe the result.

The combustible mixture can be drawn into the cylinder or not. In the first case. no problem. In the second. there is no compression in the crankcase, so the gasket must be changed.

Opinion of expert Kuznetsov Vasily Stepanovich

When replacing it is necessary to use a sealant to ensure better tightness.

How does the mechanism work

Almost all tools, and foreign ones (Husqvarna, Makita, Stihl, Partner 350), and Chinese chainsaws, and domestic (friendship, Urals) are arranged the same way. Therefore, to find the reason why the device does not start and stalls is not difficult.

There are four elements in which problems may arise:

  • Fuel for which the carburetor is responsible;
  • Lubrication;
  • The air that enters the air filter;
  • Spark, the quality of which depends on the ignition unit.

All of them depend on each other and interact with each other. If any element works incorrectly, then the saw stops working.

To begin with, all the tools start in different ways-on hot and cold. Two frequently used mechanisms are responsible for this process.

Be sure to see what is written in the user’s instructions. It indicates that when turned on, it is necessary to make sure that the emergency stop brake is recorded. But it is much more difficult to start a saw with a brake, so sometimes it is better not to turn on the brake.

As you can find out from the instructions, there are a fuel tank and engine inside the case, and the saw part (tire with a chain), handle and starter are outside.

First you need to figure out how exactly the tool does not start. For example, the saw starts up, but immediately stalls, or loses the power of work, the quality of the saw.

Perhaps interruptions in the work occur due to problems in the engine. But I would not recommend it immediately to disassemble it. It is better to look for a problem from the simplest option.

It is very important to take into account the quality of fuel. If the mixture is prepared incorrectly or has deteriorated over time, then even such reliable tools as the Urals or Husqvarna 145 will not work. The instructions must indicate proportions and special oil for your chainsaw.

Another common problem. during the start, the user floods the candle. It needs to be examined if it is completely dry, then the fuel does not go to the cylinder.

If you see a black fuel or a lot of fuel, then perhaps the carburetor incorrectly regulates fuel supply.

If your saw.tool starts up, but immediately stalls, then the problem needs to be sought by a jacket of a carburetor or a fuel filter. Perhaps they clogged.

In order to check if the saapun is damaged, it is necessary to disconnect the fuel hose from the carburetor and see if the fuel mixture flows from it.

If the saw does not start hot, then the problem can be in the muffler. Sometimes it clogs from the exhaust itself.

Often often a saw breakdown occurs due to a small amount of lubrication for the circuit. This happens with clogged channels or leaking oil pipeline.

Also inspect the connections of the tubes with oil pumping fittings, do they leak.

Very bad when the breakdown arose in the cylinder. When examining it, you can detect irregularities or chips, this may be the cause of the problem.

The lawn mower will not start or start, but stalls. What is the reason?. Agrotechervice

The lawn mower is not started after winter

In such cases, it is necessary to conduct maintenance of the unit. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean each node, rinse. Pour the filters with air. Pay attention to the quality and octane fuel number.

It must be taken into account that the products of such well.known companies as Stihl, Husgvarna and other brands will not work on a cheap octane number of gasoline.

For them, suitable fuel from the AI ​​brand. 92 and higher with car gas stations and that, with well.proven ones, since gas stations are also bad gasoline.

On the use of highly octane and high.quality gasoline, it will depend on how long the lawn mower will be used and how much it will last.

One more fact must be taken into account that with the long storage of diluted fuel mixture, it falls working qualities, which also leads to the consequences in which the lawn mower will not start.

Quickly Unflood A Trimmer Using NO Tools

Therefore, it should be diluted with portions, that is, the amount of a mixture that is produced at a time. The operating instructions clearly describe and are given clarifications on the proportion of mixing gasoline and oil.

Straighten compliance with the correct proportions will at least save you from several questions, why the lawn mower will not start and what to do in such cases.

The lawn mower starts and stalls. What to do?

There is a spark, and everything seems to be normal, but the lawn mower is not started, in such cases, you should check the air access valve into the fuel tank. Clogging of the valve leads to the creation of a vacuum in a tank, in which the carburetor does not receive gasoline, so the lawn mower will start, but then it will die out.

To exclude this reason, you need to clean the valve and try to get a lawn mower with a not fully twisted tank traffic jam. 2. If at the same time the lawn mower is not started, you should remove and clean the fuel filter, as well as check all the parts of the carburetor, and then try to start.

The lawn mower is not started again, the air filter is disconnected, try to get without it if the gas station has started to mean the reason in the air filter, replace it.

The lawn mower is not started, the spark is gone

The loss of the spark entails a check of contacts and the correctness of the clearance between them, conducting the wire to the candle and the candle itself. A method of checking the spark. to unscrew the candle, connect the wire to it, attach the candle sideways to the casing of the engine and pull the lawn.mower as if starting the starter several times, while you need to look at the corner and contact of the candle, the spark should run between them.

If there is no sparks, take a new candle to do the same procedure, if the spark is not traced, the problem in the wire or contacts means it, it is better to replace them.

The lawn mower is not started on a cold

When starting a cold motor, it is not recommended to press the gas. Having tilted the lawn mower so that the air filter is on top, click on the fuel suction button 5-6 times, install the function of switching functions to the Start position, pull the starter’s cord several times until the motor starts up. After a few seconds of the engine, turn off the start system.

The lawn mower is not started on hot

If the lawn mower was recently at work and did not have time to cool down but did not want to start. press the gas trigger, sharply pull the starter’s cord several times until the engine is started and only then the gas trigger is released. If a lot of time has passed and the lawn mower managed to cool, then it must be started as with cold. If the above methods did not help, the lawn mower did not start, then you should contact the service center.

The lawn mower is poorly started on hot

The hot engine is poorly started

There are situations when the car does not start, after it worked, standing only a couple of minutes. Drivers of completely different cars face such inconsistent.

In the main thing, this happens specifically on gasoline engines.

Regardless of what the engine works on, the carburetor or with an electric control unit, such a non.bond occurs as the motor is poorly started on the hot or does not start at all to the hot.

Carburetor

So, if you have a carburetor engine, and it does not start on a hot. then you need to find what the wrong. There can be only two obstacles here, and both of them are associated with fuel.

In the first case, obstacles can be with fuel. This often happens when the driver refuel at another gas station, on which he had never before.

The 2nd reason is the carburetor, and more precisely its settings.

The main inconsistent why the carburetor engine is not started on the hot, it is that the motor has a huge temperature during operation relative to the carburetor.

When the motor is started and asks for fuel from the carburetor, everything is fine, fuel circulates and cools the carburetor and engine. But when it drowns after long.term work, the engine gives its heat to the carburetor, and it warms up.

At this moment, gasoline, which was pumped up in a carburetor, begins to evaporate, traffic jams from the air begin to be created in the system that do not allow cars to start.

Attention should be directed to the fact that if the machine does not start on a hot engine, then do not try to do it. The fact is that the carburetor pumps up the fuel from the main tank and later, as the car cools down, there will be more fuel than necessary, and it will simply fill the candles. After which you will have to not only expect the carburetor cools down, and to clean or change candles.

In order to avoid this obstacle, it is necessary without the help of others to imprison the fuel mixture. This means that in the fuel consistency there will now be more air than gasoline. You can do this using an accelerator pedal.

In order to impoverish the fuel mixture, it is necessary to press the accelerator pedal. Usually it must be squeezed for one second, but on some engines the pedal must be squeezed out quite.

It must be emphasized that the accelerator pedal in your car must be squeezed only once, when you press the accelerator pedal, fuel will flood the candles.

The third inconclusive, because of which it can poorly start on the hot, in the motor, where the carburetor is responsible for the injection of fuel, it is that the gasoline pump in the tank is faulty or overheat or overheat or overheat or overheat.

The problem is that earlier gasoline pumps could not work at high temperatures, and during work they often became unusable or simply turned off than they did not let the machine start up. In this case, you should simply change the gasoline pump more modernized.

In the near future, pumps for the supply of fuel are already able to work in fact in all weather and without interruptions. The cost of such pumps is little higher than for a standard carburetor from a car of the Volga manufacturer.

Injector

To chagrin, it happens that it is poorly started on a hot and such motor. In fact, in a car with such a engine there may be even more circumstances than in the carburetor motor. As implies a car with an injector engine operates one hundred percent in automatic mode. Therefore, here all the work is based on the testimony of different sensors.

The 1st and main reason why it is not started by such a engine when it is heated, consists in the incorrect operation of the sensor, which indicates the temperature of cooling water.

The fact is that when the sensor indicates an incorrect temperature, the electric unit gives an incorrect command to nozzles that inject an unnecessary dose of fuel. It often happens that the sensor simply clogged, because of this it does not indicate the correct temperature of cooling water.

In this case, you just need to clean the sensor and install it back. If the sensor has become unusable, then it must be changed by the new.

I immediately draw your attention that it is not a carburetor to chagrin. (My website

trimmer, husqvarna, grass, poorly

The 2nd reason why the car is not started is that fuel nozzles are leaky.

In fact, everyone knows that the nozzle should serve fuel in the combustion chamber under pressure, but it will not be able to do this if the nozzle body is leaky. In this case, the mixture will be rich in fuel and poor in air.

Due to the fact that there will be no air in the combustion chamber, the fuel will not be able to fire. In this case, it is necessary to inspect the nozzles in a special device.

If when checking it was found that the nozzles no longer began to be sealed, then they must immediately be thrown away and new. The inconsistent is that even cleaning with ultrasound will not help to solve this.

The subsequent prerequisite for which the machine does not start is the one that is faulty of the fuel pump of the highest pressure. The ignorance here lurks in the fuel pump of high pressure. Husqvarna R 53 The lawn mower starts poorly and Trithu is better started.

It will not be difficult to check this, and even the most inexperienced driver will cope with this. In order to check the performance of the plunger pair, you just need to pour it on the back of the fuel pump with high pressure with cold water in order to cool it.

If after that the engine starts immediately, then the deficit is only in the plunger pair.
