Benzotrimmer does not enter the fuel in the cylinder. Is there a spark

The causes of breakdowns of gasoline and electric trimmers

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen in the engine area.

Damage of gasoline trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:

  • engine breakdown;
  • problems with the carburetor;
  • problems with the supply of fuel;
  • muffler malfunction;
  • gearal breakdown;
  • The starter broke;
  • Air filter problems;
  • Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

It should be noted that the elimination of some of them is best entrusted to the specialist.

Basically, the trimmer for the grass ceases to work normally in the following cases:

  • Electric cable malfunction;
  • The control button is faulty;
  • burned engine winding;
  • Contact joints break on the engine.

Why is the gasoline trimmer not starting for the grass

The reasons why the gasoline trimmer for the grass stopped starting is different, therefore, a phased diagnosis of the apparatus is required.

Fuel tank (fuel quality)

Remember that always before starting the unit, a check of the presence and quality of fuel is required. In this case, you should not be greedy and save, as well as “clever” about the amount of oil added. Everything must be done according to the management attached to the apparatus, since when the piston group fails, its replacement will cost about 70% of the total cost of the trimmer for the grass. Pour fuel due to the fact that you will fully conside it when performing work. After a while, the gasoline remaining in the tank loses its properties and can harm the engine. Therefore, do not prepare the mixture for the future and in large quantities. If the lawn mower starts poorly, try to drain the “old” fuel from the tank, and season it with a freshly prepared mixture.

Important! To refuel the device with fuel, the origin of which is unknown, fraught with negative consequences. Gasoline should be of high quality, bought at a gas station, and its brand should be not lower than AI-95.

Candle and candle channel

So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is worth checking the candle channel: whether it throws it with a combustible mixture. Often users transfer the air damper to the “OFF” position when starting, and when the engine started, they do not transfer it to the “ON” position, after which it stalls. Further, an attempt to start the internal combustion engine to again leads to the fact that it floods the candle with gasoline, and the start becomes impossible. To diagnose and eliminate the possible problem in this node, do the following.

  • It is necessary to unscrew the spark plug, wipe it well and dry it. When installing a candle in the ICE cylinder, it should be dry.
  • Draw from the combustion chamber the fuel accumulated there. This is done through the hole from which you twisted the candle.
  • In the presence of soot on the electrodes of the candle, it must be removed either with a thin file or a nail file.
  • Do not forget to put the gap between its electrodes before installing the parts in place. The gap on the candle should be 1 mm. As a probe to check the gap, you can use a coin.
  • Next, collect the block, read the start instructions and try to start the engine again.

If the engine does not start, then you will need to check the spark. For this:

  • unscrew the candle;
  • put on it a cap of a high.voltage wire;
  • Touch its metal part to the cylinder body (to provide contact, you can insert a tubular key) as shown in the figure below;
  • pull the launch cord so that several engine speeds occur.

Normally, with each piston roll between the electrodes, the candle should slip a spark. If there is a spark, then the reason that the internal combustion engine is not launched should be sought in other nodes of the device.

For a better understanding of the process, how to test the candle for the presence of a spark, you can use this video where the check is shown by the example of the Lawn Mushiel “Soyuz”.

If there is no spark, then in the beginning check the cable connecting the candle to the coil. perhaps the reason is in it. You can call it with a tester. In case of detection of the rupture of the chain, a high.voltage wire will require a replacement.

Also the reason that the spark has disappeared is a malfunction of the ignition coil (magneto). The figure below shows what the coil (magneto) looks like from the gasoline trimmer for Patriot grass (Patriot).

To exclude the malfunction, it will be necessary to use a tester to check the Magneto trimmer for the grass, namely, its primary and secondary winding. On the primary winding, the resistance should be in the range from 0.4 to 2.0 Ohms. If the device shows 0. this means that there is a short circuit in the winding, and if infinity is a clear sign of a chain break. The resistance on the secondary winding should be in the range from 6 to 8 kOhm.

On some coils, it can reach the value of 15 kOhm.

Air filter

If your lawn mower does not start well or stalls immediately after starting, you should pay attention to the air filter, since it can be clogged, as a result of which the air does not enter the combustion chamber, and fuel ignition does not occur. To check if the filter is the case, remove it and try to start the engine. If he earned, then the reason was found. The filter needs to be replaced or rinse well and dry before installation. In the case when you find the oil in an air filter, it must be washed with gasoline, squeezed well and dry at least 2 hours before installing in place.

If the unit does not start with an air filter, it is still recommended to check the fuel filter.

Fuel filter

This filter cleans fuel of possible pollution. If it is scored, then gasoline does not enter the cylinder, and, accordingly, the unit does not work or stalls after starting. The fuel filter is located at the end of the fence hose, which is located inside the fuel tank. To get to the filter, it is necessary to extract a cork with tubes emerging from it.

When extracting traffic jams, a fence hose can disconnect and stay in a tank. It is extracted with a tweezer.

Next, remove the old fuel filter from the hose and put on it a new, pre.acquired. You can also clean the fuel filter if you do not have new. The filter must be fixed on the hose using a spring latch.

Install the fence tube on the cork and insert the last into the tank.

The reasons

Trammers for grass are reliable and durable (of course, subject to proper care). Most often, malfunctions arise due to contamination of structural elements.

If the engine of your lawn mower does not start, does not gain momentum, does not reach the power you need or suddenly stalls, it may be a reason:

  • low.quality fuel (fuel mixture), it can be in long.term storage or in non.compliance with the recipe for the preparation of the mixture;
  • The grass was wound on the shaft of the fishing/knife head;
  • clogging of the air filter/muffler;
  • Balance of the carburetor.

Ways to eliminate problems

The first three reasons are quite simple to eliminate. If the matter is the mixture, it is necessary to pour old fuel from the tank, prepare a new emulsion from high.quality gasoline and engine oil (if your motor requires a mixture) and pour it into a fuel tank. If a trimmer for grass works on clean gasoline, it’s still easier.

In the second case, it is necessary to carefully release the details of the trimmer for grass from the wound grass.

If the filter is clogged, you can try to rinse it. If this procedure has not brought the effect, replace it with a new.

The last reason why the lawn mower does not work properly will require you a little more knowledge and skills.

In order to properly adjust the carburetor of the lawn mower, it is necessary to observe a certain procedure. First of all, carefully clean the air filter. The easiest way to rinse it (it is advisable to carry out the filter with water regularly after 9-10 hours of operation).

After that, in the diagram of your trimmer for grass, which is in the instructions for the operation of the device, find the adjustment screws. Usually there are three of them: the first is responsible for the supply of fuel, the second. for idle, but the third is designed to limit the number of maximum engine speeds.

Next, you should turn on the unit and wait for the engine to warm up.

Slowly twist the first adjusting screw (fuel mixture). Catch the moment when the motor begins to stall, and turn the screw in the opposite direction 45 degrees. If you did not have time and the motor stalled, the screw should be turned 90 degrees. Open the throttle and see how the speed is going. Next, you should slowly unscrew the screw (each turn. the same 45 degrees) until the moment when, with full gas, the motor begins to firmly issue maximum revolutions.

The second screw, as mentioned above, controls the engine speed at idle. Weakening it, you reduce the number of revolutions, tighten. increase. The screw must be adjusted so as to ensure confident operation of the motor at small speeds. Accelerate the engine for better starting a little. At the same time, make sure that before the movement of the knives/coil with the fishing line, the motor makes several dozen revolutions. With poor starting the engine, screw the screw slightly.

After you have adjusted the first two screws, test the operation of the device at the maximum engine speed. If necessary, you can limit it (maximum). this will serve as protecting the motor from “boiling”. To do this, you need to do the third screw. Unscrew the fixation nut until the moment when the control screw can be calmly turned. To increase the maximum speed, the screw must be loosened to reduce. on the contrary, tighten. Fix the screw position with a nut. Test the work of the motor again.

Spend the position of the screws regularly. a high level of vibration characteristic of benzocoses can cause their involuntary shift.

Remember that carburetor adjustment is not the final procedure. During operation, Motokos, most likely, you will have to mess with it more than once, because an unbalanced carburetor is both an increased fuel consumption and a quick failure of the candles, not to mention reducing the power and productivity of the device.

Signs of common faults

Knowing the internal device of the lawn mower and the principle of its operation, you can easily eliminate the malfunctions with your own hands. Some breakdowns are most often found and they are distinguished as the main.

  • The engine malfunctions should be sought if the lawn mower does not work or does not even start. It is also worth paying attention to this part of the braids for grass, if during operation unusual noises are heard or strong vibration is felt. Clotting of the air filter can also lead to problems with the engine.
  • If the fuel does not enter the combustion chamber, then you should look for the cause in the suction of the fuel filter. It is also worth looking at it if the tool does not work at low speeds.
  • The starter’s grille was clogged. the reason for the engine overheating and its termination. The starter can also fail when the cord tears when it is too sharp.

Methods of elimination

Repair of a lawn mower is best started with a phased check of the main components. The first thing to check is fuel in the tank, as well as the presence of lubricants on the main nodes of the tool. It is also important to know what quality and what is the proportion of the fuel and oil used. If something is wrong, then the piston system may fail, and its replacement is expensive.

Next, it is worth evaluating the serviceability and performance of the spark plugs. The result is evaluated by the presence of a spark when there is contact with the tool body. If the malfunction in the candle, then you need to remove the voltage wire from it.

Then the candle is unscrewed by a special key.

In case of contamination, it is recommended to replace with a new one and drying the candle canal. This is also done if there are cracks or chips on the candle housing. The gap between the electrodes is set 0.6 millimeters. Squeezing a new candle is also produced by a special key. At the end, the voltage wire must be connected to it.

The inspection of filters, both fuel and air. If the blockages are strong, then the best solution will be their replacement. You can try the air filter with water with the addition of a detergent, and then dry. It is also sometimes soaked in gasoline. After drying and installation, it is important to moisten the filter with oil, which is used in the mixture with fuel.

It is very easy to eliminate the problem in the form of a stalling lawn mowed immediately after starting. it is enough to adjust the carburetor according to the scheme given in the documentation. Sometimes you have to send the valves of the carburetor to facilitate the supply of the mixture in it.

Sometimes the lawn mower stalls due to the receipt of a large amount of air. In this case, it is necessary to increase engine speed to release it. It is also necessary to check the fuel hose for possible damage. If necessary, it is changed to a new.

It is important to maintain a gearbox clean, and its gears should always be treated with a special lubricant. It is worth noting that it is not always possible to repair a gearbox and starter on your own, therefore it is more advisable when breaking down these nodes to replace them with new.

When reducing the engine power, it is worth paying attention to the exhaust muffler, or rather, to the net in it. She can clog because of soot from burned oil. This malfunction is solved cleaning the grid. You can do this using a small brush with wire or nylon bristles, as well as compressed air.

Clutch in benzocoses can break due to wear of the pads or a bursting spring. In both cases, the failed spare parts are replaced. Sometimes the clutch coupl is unusable, it can also be replaced with a new. over, on sale there are both couplings in full assembly and individual elements to them (washer, drum, etc. D.).

Ways to eliminate breakdowns

It is no secret that the best and most effective way of repairing is a prevention of possible malfunctions. As already noted, one of the key points is how correctly the gasoline-oil mixture is prepared. Its components should be gasoline at least AI-92 and high-quality motor oil. The proportions, taking into account the mixture, are indicated in the manual of the manufacturer, which is included in the supply of any gasoline trimmer for grass. As a rule, oil to gasoline is added using an ordinary medical syringe. In a similar way it is easiest to observe the appropriate proportions.

Quite often, when problems with the launch of motorcycles arise, the owners of the tool try to carry out repairs with their own hands. In the presence of the necessary knowledge and skills, this approach will significantly reduce operational expenses. First of all, it is worth checking the fuel system and, in particular, the filtering element. If clogging is detected, the filter will be easiest to replace with a new. If an air filter has become source of problems, then you can get out of a difficult situation even in the process of work with minor time costs. The following actions will need to be performed:

  • remove the filter element;
  • Directly in working conditions, you can rinse the filter used by gasoline;
  • When operating, braids for grass or at a summer cottage for cleaning use water and simple detergents;
  • After washing, the part is carefully rinsed and dried;
  • A completely dry filter should be lubricated with engine oil;
  • excess lubricants are removed by compressing the filter element with the hands;
  • The cleaned part is put in place and the plastic cover is attached with screws.

If the described actions did not provide a positive result, then the next step will be the clearance adjustment using the corresponding carburetor screw. Many publications and videos posted in the open spaces of the World Wide Web are devoted to this topic. When trying to solve the problems under consideration, you can take several steps.

  • The trimmer for the grass is placed on the side so that the “air” is from above. This will allow the fuel mixture to enter the lower part of the carburetor. Often, attempts to launch the internal combustion engine are successful if you pre.dismantle the mentioned part and literally send a couple of drops of gasoline directly to the carburetor itself.
  • If, after all the described actions, the braid could not be brought into working condition, then the candle and, in particular, the presence of a spark should be paid attention to. In parallel, all fuel from the combustion chamber is completely removed.
  • Often, the owners of the benzos are in situations where the fuel and air filters are clean, the candles are good, the fuel mixture is fresh and high.quality, but the internal combustion engine does not show signs of life. In such cases, experienced experts recommend using universal and proven many years of practice by launching. It is necessary to transfer the air damper to a closed position and pull the starter handle once. After the damper, the engine is opened and the engine is launched 2-3 times. In the vast majority of cases, the result is a positive.

Problems may arise with the starter itself. Often there is a cliff of the cable and a breakdown of the handle. You can cope with such troubles yourself. In other cases, as a rule, the starter is replaced. It is worth noting that the Danish device can be purchased and installed with your own hands.

The light of the ignition during the launch of the ICE of the Trimmer for the grass can be filled with fuel. Even with a high.quality mixture and the presence of a good spark, it is unlikely that you can get a device. The most effective exit will be to extract a candle and dry it. In parallel, you can check this spare part for performance, when identifying malfunctions, replace it. This procedure includes a number of simple steps, namely:

  • drown out the device and wait for complete cooling of the power unit;
  • turn off the wire;
  • extract the candle itself;
  • examine the dismantled part;
  • make sure the presence of a gap (0.6 mm);
  • screw a new, working candle and tighten it.

In practice, many repair work related to the fact that the braid for the grass has stopped starting and which sooner or later has to face the operation of a household lawn mower, it is quite possible to cope on its own. But with serious malfunctions, it will be most rational to contact a specialized service. However, the key factor in such cases will be the ratio of the cost of repair and the price of a new trimmer for the grass.

Recommendations for operation

The stability of the work of any motorcycle and the lack of problems with the launch of the power unit of such devices directly depend on the conditions in which the tool and quality of maintenance is used. And we are talking about the following basic rules:

  • In the process, it is necessary to pay special attention to the cooling system and other elements; It is strongly recommended to timely and qualitatively clean the channels located on the hull of braids for grass and ribs of the starter;
  • In the process of processing various elements, solvents, gasoline, kerosene and other effective means can be used;
  • The indicated work should be carried out after completely cooled by the power unit;
  • It is necessary to fully comply with all the rules specified in the relevant instructions drawn up by the developers of the described tool, which will avoid overloads in the heated engine, which in turn is the most common cause of serious breakdowns;
  • All fuel remnants in the internal combustion engine should be completely drained before long breaks in operation of braids for grass; It should be borne in mind that the gasoline-oil mixture quickly decays into the so-called heavy fractions that inevitably clogging the carburetor;
  • After removing the fuel, it is necessary to start the engine and let it work on xx until he himself stalls; Similarly, the remnants of the mixture will be eliminated from the internal combustion engine in full.

Particular attention must be paid to the preparation of the tool for long.term seasonal storage. This should be done to minimize the risks of problems with the launch of the engine. Competent preparation includes the following manipulations:

  • completely disassemble the trimmer for the grass;
  • Rinse and clean all the elements to which there is access;
  • examine the parts of the lawn mower in order to identify defects (mechanical damage detected in this case should be eliminated);
  • pour motor oil into the gearbox;
  • carry out high.quality cleaning from clogging of an air filter element;
  • Having appropriate knowledge and practical skills, you can perform partial disassembly of the power plant with subsequent purge and lubrication of moving elements;
  • pour the collected gasoline braid with a pre.oiled rag.

In addition to all of the already listed, it is necessary to lubricate the piston group. This algorithm provides for the following simple manipulations:

  • extract a candle;
  • translate with the starter the piston to the upper dead point (VMT);
  • pour a small volume of motor oil into the cylinder;
  • Shine the crankshaft several times.

Regardless of the cost and brand of equipment, you should clearly comply with all the requirements of the relevant instructions and adhere to the recommendations of developers and experienced specialists. Today, detailed information regarding the correct use of such technology can be easily found on many specialized sites and forums.

It is important to remember that competent operation of motorcycles and its timely maintenance (independent or in the service) is a guarantee of the longest possible service life and minimum expenses.

Next, watch the video on how to determine and eliminate the reason why the gasoline trimmer is not started for grass.

How to avoid most problems?

The work of this seasonal equipment is very affected by its proper storage. over, this applies not only to a long “rest” in the winter, but also of short intervals of inaction. To protect yourself and the technique from problems, you need to adhere to a few simple recommendations.

  • Before sending on a well.deserved rest, a tank trimmer for grass is freed from fuel remnants. To remove the entire mixture, the lawn mower is launched and allowed to work until the engine is stalled.
  • The first operation after “winter hibernation”. pouring a small amount of oil into the candle hole. Before that, the piston is moved to the extreme position. Such a lubricant will facilitate the launch and prevent premature wear of the details.

Before starting working with a motorcycle, they must check the candle and all the main equipment components.

Reasons why the trimmer for grass does not start is quite a lot. But most of them can be detected and fixed independently. The main thing is the correct diagnosis, attentiveness and sequence of actions. And about how you can cope with problems, the master from the next will tell in detail

What to do if gasoline does not enter the motor?

All work on the definition and elimination of the reasons is divided by 2 parts, that is, what can be done:

In the field

If the trimmer for the grass stalled or has become incorrectly working, and you suspect that the reason for this is the lack of fuel in the motor, then in the field act like this:

  • Turn off the ignition and remove the device from the shoulder.
  • Make sure that there is fuel in the tank, if it is over, then you find the reason, so pour new fuel, pump the primer and continue the work.
  • If there is gasoline in the tank, then wait for the cooling of the motor and pump the combustible primer, and then carefully inspect and sniff the entire fuel system. The appearance of a wet spot or drops, as well as a sharply intensified smell of fuel indicates a malfunction that cannot be eliminated in the field.
  • If there is no gasoline leakage, pump the fuel with a primer, clicking on it 3-5 times, then transfer the trimmer for the grass into the start mode and several times smoothly, but pull the tame starter cable strongly.
  • If this did not help, then unscrew the candle and make sure that it is dry (a wet candle speaks of a problem that cannot be solved in the field), pump a primer 10-15 and transferring a trimmer for grass to launch mode, 20-30 times slowly, slowly, but gently pull the hand starter cable. The lack of a positive result indicates a defect that can only be eliminated in the conditions of the workshop, even if the home.

Using a special tool and equipment

To determine and then eliminate the cause, act from simple to complex, that is, first conduct those checks that require a minimum of equipment and efforts, that is, test:

After making sure that all the actions described above did not find the cause of the malfunction, disassemble the fuel system, then check each part separately. If you do not know how to do this, contact the workshop.

New chainsaw or benzotrimmer (lawn mower) may not start.

All the reasons why the lawn mower is not started can be classified by the specifics of the operation of individual units. In the service center, the malfunctions are classified:

  • engine malfunction (piston wear, bearing malfunction, crankcase crack);
  • Fuel mixture malfunction. clogged pores of an air filter or a malfunction of a carburetor;
  • the ignition system does not work;
  • A mechanical malfunction. a leak of hoses, broken wires under the braid, rupture of the tubes.

The user first needs to check if there is a fuel in the tank. Start the launch in accordance with the instructions, putting the saw on the side. Set the air damper to the position “closed”, pump up fuel, turn on the ignition and produce 3-4 sharp jerks by the starter. If the engine has earned, open the air damper. The lawn mower is not started. we repeat the operations with a slightly open air damper.

With a unsuccessful launch, we begin to look for the reason for the refusal:

  • check the quality of fuel;
  • make sure that the candle and clean canal is working;
  • check the cleanliness of the air filter;
  • Make sure that the fuel filter is not clogged;
  • Check the cleanliness of the bastard;
  • Clean the exhaust channel.

complex reasons will be detected in the diagnosis of a malfunction, leading to the overhaul of the carburetor. Such reasons include clogging of the internal channels of the carburetor, wear on it gaskets and violation of the tightness of internal halls with a vacuum loss. DIY lawn mowing repair, if it does not start, will require patience.

Where to start the diagnosis of malfunctions if a trimmer is not started for grass? In situations where the tool stalls immediately after starting, it is worth examining the following units:

It is the breakdown of the above locations that most often leads to the fact that a trimmer for grass is poorly started. Let’s look at how to eliminate such troubles.

  • To twist the candle. Wipe it thoroughly, and then dry it.
  • Drain excess fuel in the chamber through the corresponding candle hole.
  • Clear the old candle if there is a dozen on its surface. Cope with the task will allow the use of a conventional ladies’ nail file or file.
  • When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the lumen.
  • Collect a functional block back.
  • Try to start a trimmer for grass.

It is recommended to perform a candle channel to dry for at least half an hour. However, in no case should you resort to the calcination of its elements. After all, heating the spark plug can lead to its final corruption. Что предпринять, если обслуживание функционального блока было выполнено в соответствии вышеуказанным рекомендациям, но триммер для травы не заводится, искра есть при этом?

In this case, it should be treated with gasoline threaded connection. The latter does not need to be saturated abundantly fuel. It should only be slightly moisturized. Resort to such actions should be to ensure the ignition. After all, no matter how much the candle gives a strong spark, in an absolutely dry chamber there simply will not be something to ignite.

If even in this case a trimmer for grass does not start, it is worth evaluating the quality of the contact between the high.voltage wire and the candle. In the absence of a spark (in the presence of a reliable connection between the indicated elements), most likely, the problem is caused by breakdown of the ignition unit. In this situation, you will have to turn to the services of masters who will reinstall the knot.

The stable functioning of a trimmer for grass can be impaired as a result of laying dirt in the graduation canal or the formation of a blockage on a muffler grid. This problem most often occurs during the operation of older generation trimmers. The issue is being solved by dismantling the anti.diploma mesh and its cleaning.

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. It may very well be that everything is to blame for the gathering of the needle in it. In any case, the disassembly and washing of this capricious mechanism certainly will not hurt.

In general, when a trimmer for the grass began to be capricious and stall, it is advisable to carry out complete prevention: to completely change the fuel mixture, try another oil, and also mandatory change the candle. The gasoline trimmer for the grass does not start? Reasons and decisions on. Practice shows that in many cases, it is precisely cheap low.quality candles that are to blame.

We examined the most typical reasons why a trimmer is not started for grass. If the matter is something more “exotic”, do not pass the campaign in the service center. You will probably find smaller and obvious breakdowns yourself.

In general, when a trimmer for the grass began to be capricious and stall, it is advisable to carry out complete prevention: to completely change the fuel mixture, try another oil, and also mandatory change the candle. Practice shows that in many cases, it is precisely cheap low.quality candles that are to blame.

Fundamentals of the dosage of the combustible mixture

The situation when the vase carburetor shifts is especially common. Before disassembling the causes, you need to learn a little about the principles of the preparation of the fuel mixture.

The mixture is considered normal when 14.7 parts of the air account for one part of the fuel. All other ratios are a consequence of an incorrectly configured carburetor. If the ratio is from 7 to 1 to 12 to 1, then we can talk about overflow. In this case, difficulties arise with the launch of the engine. It must be remembered that the overly rich mixture, like too poor, can be dangerous for the motor. It burns more slowly, which means there is a risk of valves. But the combustion temperature is low.

How to properly adjust

Before setting up the carburetor trimmer for the grass, it is necessary to do the following:

  • Rinse the engine;
  • replace or clean the spark plug;
  • change to a new one or clean the air filter (it is recommended to lay it out in warm, soap water, squeeze it out and let it dry well).

It is also necessary to install the cord of the right diameter in the trimmer coil or install knives-this is done so that in the process of configuration the engine has at least some load. After installing a cutting tool and starting a gasoline engine, let it warm up for 10 minutes.

If at the idle speed of the motor you noticed that the cutting tool rotates, then it is necessary to reduce engine speeds. This is done using the lower idle regulator, often marked with the letter “T”. The figure below shows the placement of regulators on the trimmer Husqvarna.

But, for example, on the STIHL trimmer, this screw may have a label “LA”.

So, turn the idle control regulator to the left, until the trimmer head is completely stopped.

To configure the carburetor, 3 regulators are used (screw).

  • The right regulator L tunes the level of enrichment of the combustible mixture at low speeds. It needs to be adjusted by the first. Get a maximum of turnover at idle. This is done using the regulator L, turning it to the left and right. After finding the point of maximum revolutions, return the regulator for half a turn to the left (against h. Arrows).
  • The lower regulator t (LA) is used to configure idle. Turning it to the left, the engine speed will begin to decline, and when the regulator is turned to the right, the revolutions will increase.
  • Left regulator h is responsible for enriching the combustible mixture at high speeds. The enrichment configuration completes the adjustment of the carburetor. Also, using this regulator, you can configure maximum speed, fuel consumption and engine power.

To exclude this trouble, adjustment will be required. With the working motor, give a full gas, then turn the “h” regulator to the right until a reduction in revolutions begins. After that, the “h” regulator must slowly scroll to the left until you hear the uneven operation of the engine. Then the regulator “h” should be rotated to the right until the moment of flat operation of the motor is heard.

After conducting the above actions, the setting of the carburetor can be considered completed. After proper adjustment, the engine must confidently gain momentum, a little four at a maximum of revolutions, and when working, an idle cutting tool should not turn. This manual is suitable for adjusting carburetors on the Huter, Patriot and others benzocos.

There are also carburetors without a screw that is responsible for enriching the combustible mixture at low speeds. That is, they have only 2 adjusting screws: a idle regulator and a quality fuel mixture regulator at high speeds. How to configure a carburetor of this type, you can find out from this video.

The lawn mowing engine does not want to start after winter

Often, with the onset of spring, most owners of benzos complain about the inability to launch the motor of this grass.shocked tool. With what it can be connected? So that the trimmer for grass in the spring after winter storage is well started, you must learn to care for it correctly. How to properly store the lawn mower in winter is described in detail at the very end of the material. Now we will figure out why it is impossible to start the tool engine after winter.

One of the main reasons that after winter the lawn mower is not started. stagnation of fuel in a gas tank. If you do not drain the fuel from the tank, and leave the tool to store for a long time, then it will naturally be impossible to start the lawn mower. The properties of a mixture of gasoline with oil fall, so as a fact we get a tool malfunction. Even if the fuel mixture has remained in the trimmer last year, it is recommended to drain it, and pour freshly prepared. After that, start the tool.

Another cause may be a malfunction of the air damper. When closing it manually, the valve itself may not work, so you start the lawn mower with a completely open air damper. In this case, the tool will not start the cold, as there is a large air leak. The video below tells why a trimmer does not start for grass for cold.

In addition to these reasons for the impossibility of starting the gas mowing engine, there are others, which are also important to mention:

  • Disciplings of the Electrodes of the candle. before starting the trimmer for the grass after winter, you should twist the spark plug, inspect it, clean, dry and set the gap
  • Damage to the high.voltage wire. During the storage of the tool, the high.voltage wire could crack, damage or could gnaw the mice. Make sure the integrity of the armored pipeline if the trimmer for the grass does not start after winter
  • Oxidation of wire contacts. This usually happens if the tool is stored in a room with high humidity
  • Check the serviceability of the ignition coil. During the winter, this detail could fail, and cause a difficult to launch the tool
  • Carburetor adjustment. it is recommended to configure the carburetor after the winter. To implement this, the tool should start, therefore, if it is impossible to start, it is recommended to pour 20 grams of fuel mixture into the candle hole, and launch the motor
  • To perform all the above actions, since during a long.term storage the hole of the saapoon, filters, as well as corrosion on the walls of the exhaust system could form

Diagnose the tool, and only after that resort to a more serious repair. cleaning the carburetor.

HOW TO MAKE A START-UP Oleo-Mac SPARTA 25

The trimmer for the grass is not started due to the malfunction of the carburetor

One of the most difficult reasons for the impossibility of launching a lawn mower is a carburetor. This mechanism is responsible for the preparation and good supply of the fuel-air mixture to the cylinder. If the carburetor is clogged or adjusted incorrectly, then the lawn mower may not start or work unstable. Detailed instructions on how to adjust the carburetor on a benzocosa is described in this material.

If the adjustment does not help restore the stable operation of the tool engine, or the trimmer for the grass does not start at all, then the carburetor should be removed and repair it. The entire repair of the carburetor is that you need to disassemble it, clean all channels and constituent elements. If necessary, replace the failed details. membranes, filters, etc.P.

If the suspicions fell on the carburetor, then you should pay attention to the following types of malfunctions:

  • Canals and nozzles clogged. special liquids can be used for cleaning, however, it is best to disassemble the mechanism with its thorough flushing. The reason for the clogging of the channels and jackets of the carburetor is the storage of a tool with fuel in the tank
  • Wear of the carburetor gaskets. rubber seals contribute to the fact that the tightness of the mechanism is disturbed, as a result of which the serviceability of the functioning is violated
  • Memory of carburetor membranes. they are responsible for downloading fuel to the device

To make sure the CPG malfunction, you should check the compression, which is described above.

Why is a trimmer not starting for the grass: the main malfunctions and their elimination

As already noted, such situations are characteristic of trimmers who were inactive for a long period of time. Therefore, after detecting the problem, you need to immediately take up the search for a malfunction.

Fuel as source of problems

The first stage is checking the presence of fuel and its quality. First of all, they are convinced that there is a fuel in the tank. Those who have acquired the unit recently, often forget that the trimmer for the grass needs refueling. If there is no fuel, then the equipment simply cannot work.

If there is a fuel in the tank, but the trimmer does not start for the grass, then the owner needs to check whether he is acting correctly. In this case, it is recommended to study the instructions. If the launch is made correctly, then the malfunction can cause the inappropriate quality of the mixture.

  • Oil. It should be special. intended for two.stroke engines. It is not recommended to save on the product, since the life of the equipment depends on the mixture. Trammers for grass with a four.stroke engine require pure gasoline, it is not mixed with butter.
  • It is necessary to use not only high.quality gasoline, but also the brand that is recommended by the manufacturer of a particular model. If it is not possible to find out what fuel is necessary, then it is recommended to choose either AI-95 or AI-92, and the last gasoline is a favorite, since the first has additives that react with two-stroke oil. Other brands do not advise using.
  • The correct preparation is shifted for a benzotrimer. It is noted that at first this stage is paid to maximum attention, but over time, kosari begin to mix the composition “by eye”, and this is already a serious mistake. The correct ratio of gasoline and oil is 25: 1. For a liter of the first, 40 ml of the second, two.stroke. Motor oil intended for a car is an inappropriate option, since at high temperatures the liquid loses (partially) lubricating properties.

The correct storage conditions of the fuel mixture are important. To save time, some owners prepare it for the future to use it in the coming weeks. This option is contraindicated, since the prepared fuel mixture quickly becomes unsuitable. The reason is the precipitation of oil loss. With this change, both oil products lose their properties. Even repeated stirring is not able to restore the initial quality of fuel. Therefore, they recommend preparing a certain volume: 2 liters, no more.

If everything is in order with gasoline and oil, then they start diagnostics. to check the spark plug.

Candle and its condition

At this stage of diagnosis, you need to stop in more detail. Most experienced owners who are already familiar with the question of why a trimmer for grass does not start, first of all check the state of contact contacts. Diagnosis of this element is carried out as follows:

  • First, the spark plug is unscrewed, then inspect. If the electrodes are in perfect condition, then they should have a carpet whose color resembles a brick. Wet element, or white, black plaque on contacts indicates the presence of any malfunction. Pink and red electrodes. proof of a large number of additives in fuel. Such a mixture must be replaced.
  • In the event that the spark plug is wet, this means that the combustion chamber has unbroken fuel. It is left in place. Candle contacts are cleaned, then dried (calcination is prohibited). After this stage, the candle is connected to the nurser.
  • Then the ignition is turned on, the frontier handle is pulled. When everything is in order with the element, it must issue a constant spark. If it is weak or completely absent, then the verdict is one. you need to replace the spark plug.

There is another reason why a trimmer is not started for grass. This is a big gap that appeared between the contacts of the candle. A distance of 0.7-1 mm is considered normal. To correctly adjust the gap between the electrodes, use special probes.

If there is no such device, then the folk method is used. A razor blade breaks, folds its parts together. Then this “probe” is inserted between the contacts. Ideal. blades that enter tightly.

The problem is in the fuel and the carburetor

If there is a spark, and a trimmer for grass still does not show signs of life, then nuisance can lie in the fuel supply to the combustion chamber. To make sure that this node is to blame, they perform such actions:

  • They are typed in a syringe or poured into a lid from a plastic bottle of about 20 ml of fuel.
  • Then, through the candle hole, the fuel is neatly poured into the combustion chamber.
  • The candle is returned to the place, put on the imminent, the engine is launched.

In the event that the trimmer has started for the grass, the problem may be in the fuel and carburetor. Когда эффекта от проделанных манипуляций нет, диагностику продолжают — проверяют высоковольтный провод. At the slightest suspicion, this consumption element is replaced by a new.

What to do if the engine is a trimmer for grass still refuses to work? In this difficult case, you can follow the following recommendations:

  • In doubt about the candle and the high.voltage wire, it is better to immediately replace them.
  • If, when checking the new sparkling candle, it was not possible to achieve a spark, then it is almost possible to say with complete confidence that the ignition unit is faulty. the coil came out of the system.

Check its serviceability simply: they twist the candle, then it is led to the trimmer body for grass. If there is no spark when the starter jerks, or it does not appear every time, then a new coil is required. This element can also be replaced independently.

How to avoid most problems?

The work of this seasonal equipment is very affected by its proper storage. over, this applies not only to a long “rest” in the winter, but also of short intervals of inaction. To protect yourself and the technique from problems, you need to adhere to a few simple recommendations.

  • Before sending on a well.deserved rest, a tank trimmer for grass is freed from fuel remnants. To remove the entire mixture, the lawn mower is launched and allowed to work until the engine is stalled.
  • The first operation after “winter hibernation”. pouring a small amount of oil into the candle hole. Before that, the piston is moved to the extreme position. Such a lubricant will facilitate the launch and prevent premature wear of the details.

Before starting working with a motorcycle, they must check the candle and all the main equipment components.

Reasons why the trimmer for grass does not start is quite a lot. But most of them can be detected and fixed independently. The main thing is the correct diagnosis, attentiveness and sequence of actions. And about how you can cope with problems, the master from the next will tell in detail
