trimmer for grass gasoline sharply stalled and does not start

In order to most accurately determine the cause of the trimmer malfunction for grass of any brand (for example, echo) and find out the possibility of eliminating it, you need to install, when performing what action the device stalls. The engine can turn off both at idle and at high speeds, heated under load or immediately after starting and t.D.

If you stalled after starting

If the technique starts and stalls immediately after starting, this indicates the wrong settings or deducting the device. As a result of this, the fuel enters the engine unevenly, which leads to significant vibration and disconnecting the trimmer for the grass. To fix the breakdown, it is necessary to reconfigure the device according to the user management.

Another probable problem is the blockage of the valve supplying the gasoline mixture. It must be cleaned.

On a note! If the trimmer for the grass starts, but immediately stalls, it may also mean that the fuel is moving to the carburetor with difficulty. Weakening the valve will help to eliminate the problem. this will provide uniform and free circulation of fuel in the device.

Another possible reason is the damaged fuel intake hose. Air can penetrate through cracks and holes into the system. To solve the problem, you need to increase the engine speed in order to get rid of air bubbles that have penetrated the device.

If you stalled after gas supply

Owners of gasoline braids often mention that the lawn mower stalls when you press the gas. Usually such a breakdown occurs due to problems in the carburetor. A failure in his work can occur due to long-term storage, use in difficult conditions, significant overload of the motor. The symptom of such a breakdown will be vibrating movements of the device during operation.

On a note! Users familiar with the repair of a car carburetor can try to restore this important node of the trimmer for the grass on their own, using the instructions for operating. Otherwise, the correct decision will be to seek help from the service center representatives.

Sometimes a trimmer for grass stalls when you give gas because the fuel valve is clogged. This interferes with the supply of gasoline. To eliminate the problem, it is enough to loosen the valve. Thus, normal supply of carburetor fuel will be restored.

Another possible reason why the lawn mower stalls when gas is supplied is pollution of the soundtress (check valve). This detail prevents the appearance of a vacuum in a gas tank. If it is clogged, the air does not flow, which means that fuel does not go to the carburetor. To eliminate the problem, it is necessary to clean this element.

Why does a trimmer for grass stall when you press the gas?

As you can see, the reasons why the trimmer for grass can stall when pressing for gas, a lot

That is why it is important to monitor the state of your assistant, to check the condition of all systems of the mechanism in time

Before you understand why any of the instruments of a summer house or a professional working with a motorcycle (benzocosa) stalls-it is worth distinguishing between two main situations when it happens. First, this is when the tool does not start after you have made the purchase, and the second. being in operation. So, we will analyze both.

After starting.The case stalls the case if the carburetor is incorrectly configured or it was swollen. Fuel is supplied unevenly, respectively, distinct vibrations occur.
When heated. The situation when the mechanism starts and works, but gradually “chokes” and stalls on the go. when gasoline boils in the carburetor, or the damper in the carburetor is not disk, but rotary view. In such cases, it is better to replace the carburetor itself. There is an air leakage option. when a coil or wire is broken in the ignition.
At high speeds. This also occurs from the rounding of the carburetor or clogging the lid on the gas tank. It is worth trying work with a slightly parted valve. Be sure to check the fuel intake hose. it can be a crackling or poorly attached to the base.
He is not gaining momentum. As the main reason why the engine is not gaining momentum. an air filter clogged. It is possible to subside a cable in a carburetor, a breakdown of a carburetor and the occurrence of problems with the motor drive mechanics.

There are times when the detail of the mechanism requires mandatory replacement, so we are always happy to offer spare parts for the lawn mower

It is important to understand that sometimes saving on minor elements can lead to a breakdown of such global components as a carburetor or engine. Therefore, competent operation and timely replacement of the necessary particles will provide you with full work with pleasure

A gasoline trimmer for grass is not started. 10 possible reasons

Before trying without the help of others to do the work of the tool, closely study the management of its operation. Maybe the information contained in it will stumble you upon a particular idea. When working in the load, the trimmer for the grass stalled and no longer starts.There is a spark.Gasoline acts. In an unpleasant case, you will have to find the cause of the malfunction by selection. Why doesn’t the lawn mower start: floods the spark plug, after winter, under load and other reasons for the breakdown of a gasoline trimmer for grass. It may be one of the subsequent:

The switch on the bar has not been transferred to the “v.””. This is one of the simple actions, but from time to time the brand new are blurrying to turn on the tool before starting it.
Similar errors include the lack of fuel in the tank. If the fuel ends, and you forgot about it, just pour into the tank (usually placed near the motor) AI-92 gasoline.
Absence, inappropriate mixture or incorrect proportion of oil for engines. In the standard, less than 50 g of oil should often be added. I don’t remember a trimmer for Homelite grass, it is chasing and starts to start poorly in the time. This will serve as an additional lubricant and will support the engine of your trimmer for grass in working condition. Also consider that oil is of various types (“synthetics”, “semi-synthetics”, “mineral water”)-they all affect the operation of the mechanism differently.
If a trimmer mowel for grass does not start after winter, drain fuel remaining in the gas tank and change it to the freshest. This is especially burning for small low.power trimmers with malhangic engines sensitive to poor consistency. In addition, during the winter, a precipitate can form on a gas tank day, which is due to which the tasks with the operation of the device appear.
Excessive swing of fuel can also become one of the circumstances that the trimmer for the grass has not stalled and does not start. Когда воздушная заслонка перекрыта, свечу заливает топливом. It should be turned and dried, and then stick in your place and try to launch the engine, holding the gas trigger. STIHL 180 chainsaw is not started? Reasons and decision! To date, the manufacturer of STIHL has a leading place among other companies that arbitrarily. It is better to check it for the presence between the electrodes of the sparks before that. If there is no spark, the candle should be changed.
Conclusions with the filter. trimmer for grass but not suitable for my case. Starts and works does not gain momentum. That a trimmer for grass does not start hot and even cold. If the lawn mower is not started. If your trimmer for the grass starts poorly, remove the air filter and run the tool without it. If everything happens, the filter should be changed to a new. As an option-painfully cleaning and blowing the old one, but the substitution will still have to be done at some point.
trimmer for the grass stalled and does not start? Try to clean the so.called Sapun. an element designed to smooth out pressure in the gas tank. Cleaning can be done with an ordinary long needle. The clogged sapun often becomes a prerequisite for a malfunction.
Knives are removed from the car. some models will not work under this condition.
Violation of density. You can check this using a pressure gauge. If the pressure begins to fall, you should find which of the parts of the carburetor is faulty. In most cases, carburetor laying wears out.
From time to time after a long period of work, you can see that the trimmer for the grass has overshadowed and does not start. Benzo trimmer for STIHL FS45 grass starts up and tried to start. Or not starting, MTD STC 55 P. Author. VO-1, you need to know that you should definitely take breaks. The amount of continuous work recommended for this model should be indicated in the annotation. You bought yourself a new gasoline trimmer for grass and in this case the lawn mower will not start or. Also, an overheating failure can lie in a faulty ignition coil or in the air cooling system, which prevents overheating.

Problems with the modules of chain saw ignition

Ignition modules and coils sometimes tolerate breakdowns. When everything else is checked, suspicions of them. When they fail, one of two, as a rule, occurs. There is no obvious symptom. The only thing you can do is replace the module with a new. Or even better. try to change it with a saw used. If the spark did not appear after replacing the modules, apparently you missed something.

Replacing the module is the only reliable way to check the spark. All kinds of testers, as practice shows, are untrue. The only reliable test. replacement of the coil. Another symptom that indicates a bad electronic module or coil is a spark that becomes weak when the saw becomes hot. If the saw does not start after refueling, most likely the heat of the engine eliminated the spark. A weak ignition coil is sometimes able to give a sufficient spark to start and work a saw until it warms up properly. Когда пила и катушка соответственно нагреются, сопротивление транзистора возрастает и искра становится слабой. Symptoms: the saw starts and work well in the store, for example, but at work the saw dies and does not start, it will not cool. It can be difficult for the store to prove this malfunction.

It also makes sense under these conditions, after overheating it does not start, try to unscrew and tighten the tank cover. releasing accumulated fuel gases. If the saw after that begins to start, you will think of yourself.

Replacing parts of the gaspile ignition system

Some early electronic ignition systems consisted of two parts. launch and coil module. Today they are united in one part. On saws with double ignition systems, the trigger module can be replaced without replacing the coil. This is easy work, as a trigger is usually installed with a pair of screws. When replacing this part, just remove the old module and install the new one in its place. Just make sure the new module has a good foundation. If you notice any corrosion on installation connections or if the screws are not tightly tightened, this may be your ignition problem. The modules should be well connected.

Replacing the coil is a little more difficult. The ignition coil is mounted in the fan housing next to the flywheel. The module in contact with the magnetic field of the magneto Makhovik, produces energy for the spark and contains a reference to the ignition ahead. When replacing the coil, remove the old coil and inspect it. Look for damage from contact with the flywheel. The contact between the coil and the flywheel can be caused by the weakening of the screws or wear of the main crankshaft bearing.

Even if you do not see any damage, check the crankshaft bearing. If you feel the movement and backlash in this bearing, replace the bearing. Also inspect the flywheel. If everything looks good, install a new coil. The base of the coil must be installed about 1. one.5 mm above the magnets on the flywheel. If you do not have petals, try using a business card or a piece of a pack of cigarettes as a spacer. Turn the flywheel so that the magnets stand opposite the coil. With a gasket on the spot, tighten the fasteners of the coil screws remove the gasket.

The ignition adjustment procedure

Setting the ignition system is performed simply and identical to different models of trimmers, whether it be Stihl FS55, Al-KO Sun 4125 or other lawn mower. First you need to remove the casing from the engine, having previously removed the fixing fixing. This stage of disassembly may have differences on different models of motorcycle (described below). Next, you need to partially unscrew the fasteners fixing the magneto, and turn the flywheel so that the magnets are at the top.

To make the optimal gap between the coil and the magneto, you must use a special template. It is impractical to buy it for a single use, therefore, as an alternative, you can apply a business card or a small calendar, as well as a paper sheet A4, folded four. A strip carved from a plastic bottle or other improvised materials that have the necessary thickness is also suitable. The optimal distance is usually indicated in the user guide. The selected item must be placed between the magnets and the coil.

Then the coil will be pulled to the flywheel with a magnetic field. Holding the magneto in this position, you need to tighten the fixing fastener, and then pull out the business card. After that, you need to scroll several times a flywheel to make sure that he does not touch the coil at all. The process is over. the ignition on the motorcycle is exhibited. Read more the process of adjusting the trimmer ignition system can be studied on the Internet, where many videos are available to this topic.

And again the carburetor.

Well, even if after such bullying your trimmer does not start for the grass, you can’t do without disassembling the carburetor for you. It may well be that everything is guilty in the needle in it. In any case, the disassembly and washing of this capricious mechanism certainly will not hurt. Adjustment of the lawn mower carburetor can be adjusted with your own hands, like the entire benzo tool for the garden, is not difficult to maintain equipment. Repair, configure without the help of others you can and necessary. For example, adjusting the carburetor of the lawn mower with your own hands. it is 5 minutes. The carburetor from the lawn mower is a node in the power supply system. Idle…

Many trimmers owners are faced with a problem when the device simply does not start.

One of the reasons for this may be the lack of a spark. This usually happens when the fuel floods the light of the ignition. In addition, you need to check the candles for serviceability, as this can also lead to a lack of spark.

The first sign of a faulty candle is the presence of a short circuit between its contacts, and in short. there is no spark on the trimmer.

In addition, the candle is considered faulty if it is covered with a black wet layer.

Such a layer appears from the oil combustion chamber. In such a situation, you have two exits: either clean the candle as it should, or buy a new.

there, spark, echo, checking, fuel, mixture

Sometimes it happens that the candles are clean, but at the same time, the problem can be in its isolation, which is often covered with a black dry soot.

The reason for this may be a weak spark, excessively low spark plug, low fuel quality, dirty air filter or prolonged work at idle.

Here the output is the same. clean the candle or replace it with a new. over, the candle should be replaced if the contacts are strongly worn out.

In the case when there is no spark on the trimmer, how to solve the problem you will be told by professionals for a hundred.

Sometimes, the problem can be with magneto. Magneto may become unusable due to the fact that you could pull the starter cord at the moment when the ignition was turned off, and the candle was not grounded for the mass.

Such actions can easily disable magneto. In such a situation, the only way out is to buy a new magneto.

In addition, the problem may be the ignition node. This option can be considered if the candle and wire do not have any malfunctions.

In such a situation, it is necessary to engage in the replacement of the ignition unit. It can be found attached using two screws to the engine cylinder.

To obtain free access to the node, it is necessary to remove the enclosing casing.

To correct the current situation, you will have to replace the entire node, because, as practice has shown, replacing individual parts gives insufficient result.

If there is no spark on the trimmer, it can only be fixed in one way. replace it.

over, sometimes the problem should be sought in the ignition coil. The absence of a spark can lead to the failure of the coil or a malfunction in the chain.

To check the flow of current into the primary winding of the coil, you can use the light bulb, which must be turned on instead of the coil.

Then you need to carefully examine the contacts of the interrupter. If a strong spark occurs at the time of opening between the contacts, you can be sure that the capacitor is broken.

In this case, you have only one option of further actions. replacing the capacitor.

These are the main reasons why there may be no spark on the trimmer.

How not to get confused if the lawn mower does not start

The tool, despite its small dimensions, represents a complex technical device. If you study the operating annotation, it turns out, the reasons

, why the lawn mower is not started, known and eliminated. It is necessary to alternately exclude the reasons that make it difficult to start the tool. They usually start with more affordable nodes with a slight checking check.

How not to get confused if the lawn mower does not start

The tool, despite its small dimensions, represents a complex technical device. If we study the operating annotation, there will be a reason why the lawn mower is not started, are known and eliminated. It is necessary to alternately exclude the reasons that make it difficult to start the tool. They usually start with more affordable nodes with a slight checking check.

Checking performance

Before the diagnosis of Magneto, you need to make sure that the problem is actually in this node. To do this, check the entire chain and make sure that there are no other reasons for the breakdown of the trimmer for the grass.

First, you should carefully examine the coil for the presence of cracks and other external defects on the case. Next, you will need to study all the elements and nodes conducting the current and make sure that they are clean.
The next step is the inspection of high.voltage wires. They must be working and reliably attached to the contacts, without traces of rust and with intact insulation.
The next action will be checking the candle cap. As a result of careless actions, the user often tears it off from the high.voltage wire, and then improvises and creates a home.made mount. You need to understand that any poor.quality connection in this place significantly reduces the power of the electric arc of the candle.
Then you should make sure that the candle itself is working. If you refuel a low.quality motorcycle with gasoline, the service life of this part is significantly reduced. In addition, it can be flooded or have a large incapacitance that prevents work. Sometimes the candle even takes up and does not unsc.
Next, you need to inspect the circuit switch. On trimmers and chainsaws of Chinese.made, it very often breaks.

Having performed all these actions and excluding the listed nodes from the list of possible causes of breakdown, you should proceed to check the coil. This can be done with several methods.

Method 1

The first way to check the ignition coil involves the use of special equipment (stand). At home, it is unavailable. you can find it only in service centers.

Method 2

Magneto diagnostics by means of a multimeter. a solution that can be implemented on its own if there is such a measuring device. In this case, it is necessary to perform the following.

Enable the resistance mode on the measuring device and set the value of 200 Ohms to test the primary winding.
Connect the electrodes of the multimeter to the “mass” of the magneto and the outgoing contact. If the winding is intact, the resistance will vary from 0.4 to 2 Ohms.
Turn on the 20 kOhm tester to diagnose the secondary winding. In this case, the first probe is connected to the “mass”, and the second is installed in a candle cap. Normal values-at least 4-6 kOhm. If the chain is damaged, then the tester will show infinity, and in the case of close. zero.

Accurate data about what should be the tester’s testimonies during the verification of primary and secondary winding, can be found in the instructions for using a trimmer for grass.

Method 3

If there is no multimeter, you can check the coil in another way.

Important! You need to carefully check so that the magneto does not burn. For this, it is important not to touch the cylinder by the electrode.

For diagnosis, the following steps need to be carried out:

open the lid with which the cylinder is closed;
remove the cap of the high.voltage wire from the candle without twisting the part itself to maintain compression;
Place a nail without a hat tightly in the cap, it will imitate the central electrode of the candle;
Dielectric material tie the cap with a nail to the cylinder so that the gap between the mmator of the Electrode of the candle and the mass fluctuates from 5.5 to 7 mm (the exact distance for a particular model is recommended to look in the user guide), but the part did not come into contact with the mass;
The starter several times play the start of the engine, holding the ignition button in the on the on position;
If a spark appears, you need to consider what color it is.

The white or bluish powerful spark is normal, and a weak glimpse of an orange or yellow shade reports a breakdown of the coil.

Often the cold magneto creates a powerful spark, but when heated due to a defect in the internal nodes, does not conduct current. After cooling the coil, the lawn mower starts again and mows the grass with a fishing line or knife until the magneto is heated. This is abnormal behavior, so you need to change the coil.

On a note! Similarly, the problem can occur when the candle is heated and cooled, so it is recommended to check the performance of both parts.

Correction of problems

, according to which the gasoline pump cannot be launched, can be classified in accordance with the specifics of the work of individual units. In the service center, the malfunctions are classified:

engine malfunction (piston wear, bearing failure, crankcase crack);
Fuel mixture supply malfunction. clogging of an air filter or a malfunction of a carburetor;
the ignition system does not work;
Mechanical failure. hose leaks, pierced wires under the braid, pipe rupture.

First, the user needs to check the presence of fuel in the tank. Run in accordance with the instructions, putting the saw on the side. The air damper should be installed in a “closed” position, season fuel, turn on the ignition and make 3-4 sharp jerks with a starter. If the engine starts, open the air damper. Do not launch a gasoline pump. Repeat the operations with a slightly open air damper.

The lawn mower cannot work for a long time. And the engine will overheat. The mowing can be no more than 15 = 20 minutes, taking a five.minute break. In hot noon, the work time was reduced half. When cutting weeds, sedge, the working hours must be reduced.

If the launch is not performed, we begin to look for the reason for the failure:

check the quality of fuel;
to ensure the effectiveness of the candle and cleanliness of the candle channel;
Check the cleanliness of the air filter;
Make sure that the fuel filter is not blocked;
Check the cleanliness of the respite;
Clean the exhaust channel.

complex reasons will be found in the diagnosis of a malfunction leading to the overhaul of the carburetor. For these reasons, the clogging of the internal channels of the carburetor is included, the wear on it of the gaskets and the violation of the integrity of the internal halls with the loss of the vacuum. Repair of a gasoline pump independently, if it does not start, will require patience.

Checking filters

Another common cause, due to which a trimmer for grass does not start, is the presence of a blockage in the filter area. To confirm the conjecture, just dismantle the indicated block and try to start the unit without it. If the engine of the trimmer for the grass has launched, most likely you will have to replace the air filter or at least perform a thorough purge of the old. In the presence of abundant contaminants on the surface of the filter element, it is necessary to use a new grid. Relying to such actions, you should not leave a suction pipe at all without a filter. After all, rush in this case can lead to the need to repair the entire piston group of the unit engine.

How to check the serviceability of magneto

Magneto is the main detail in the engine ignition system and is a coil with primary and secondary windings located around the core. Often, due to the malfunction of Magneto, the spark on the spark plug disappears, and the fuel ignition does not occur. To check the coil, you will need to use the tester, and perform the following actions.

On the tester, going into the resistance measurement mode, you need to set 200 Ohms. In this way, the primary winding will be checked.
Connect one tester electrode to the “mass” of the coil, and the second. to the contact emerging from the magneto. Normally, resistance should be from 0.4 to 2 ohms.
To check the secondary winding, you need to install the device switch for 20 kOhm. Further, one probe of the device is inserted into the cap of the candle, and the second is connected to the “mass”. Normally, resistance indicators should be in the range from 4-6 kOhm and above (depending on the model).

When a circuit is broken, the device will show infinity, and when close. 0 (zero).

If you have no tester. then you can use the following way, showing great accuracy so that the electrode does not touch the cylinder, otherwise the coil will burn out.

Remove the cap from the candle. You do not need to twist the candle to save compression.
You need to insert a nail without a hat into the cap. The nail should be of such a diameter to hold well in the cap.
Tie the cap with a nail to the cylinder using the dielectric, so that the gap between the electrode and the cylinder body is in the range from 5.5 to 7 mm (but in no case touch the “mass”).
Using the starter, make an imitation of engine starting several times. The ignition button should be enabled.
Watch whether the spark appears and what color it has.

Normally, the spark should be strong, white or have a bluish tint. If the spark is weak, and its color is orange or yellow. this indicates a faulty magneto.

It should also be taken into account the fact that sometimes Magneto in a cold state can give a good spark. But after heating due to internal malfunctions, the current ceases to produce. As soon as the coil cools, the trimmer for the grass starts again and works for some time until Magneto heats up again. Such a reel must be replaced.

Sometimes a similar problem with heating can cause a spark plug, even if the coil is serviceable, so you need to check both parts.

Ignition adjustment algorithm

The ignition on the trimmer is adjusted quite simply.

ICE engines are installed not only on cars or motorcycles. They are widely used in various tools, for example, such as chainsaw or trimmer for grass. In case of their malfunction, poor start, it is often enough to install the correct gap between the flywheel and the ignition coil.

As you can see, there are a number of reasons why the gasoline trimmer may not be started for grass. “Not starting up” is not the absence of a spark in why the lawn mower is not started. However, with a serious approach to the task, the malfunctions indicated in the material are quite simply eliminated with their own hands. Seek specialists for help only in case of critical breakdowns. Ultimately, the cost of independent repair with for servicing the unit in the workshop should always be correlated.
