Why the trimmer for the grass does not start: the causes of the malfunction and ways to eliminate them
It’s time to cut the lawn, and the lawn mower does not work? It’s even scary to imagine how to maintain the lawn in perfect condition with a manual tool, especially when this was not done before. If a trimmer for grass does not start, the reasons can be very different, but you can eliminate most of them yourself.
This will not need either a special tool or highly specialized knowledge. A little courage and free time to read this material. and a trimmer for the grass will not need to be taken to the master.
In this article, we will tell you how to determine what exactly interferes with the launch, we will give instructions for the repair of each node and recommendations on how to avoid problems in the future. For clarity, photos and videos await you, where the most common breakdowns are clearly dismantled.
Common causes of breakdowns
First of all, it is worthwhile to verify the simplest things: the presence and quality of fuel, the correct order of action.
Use only those fuels and lubricants that the manufacturer recommends. Gasoline with too high octane number is sometimes no less harmful than the 80th. The instruction has not been preserved? Universal can be called AI.95 with a car gas station with a good reputation.
Pour only suitable engine oil. In the vast majority of gasoline trimmers, the engine is 2-stroke, so ordinary car oil cannot be used. For a 4-stroke engine, the oil is poured separately from the fuel. over, it is not worth pouring “working out”. used, used oil.
Remember, the repair of the piston group will cost 30. 70% of the cost of the new motorcycle. Savings on the quality of combustible materials is unlikely to cover these expenses
Exactly observe the proportions of mixing gasoline and engine oil, do not lie “by eye”. For most motos, a ratio of 1:25 is recommended, that is, 40 ml of oil per liter of gasoline.
Do not cook a lot of mixtures at once: ideally it needs to be developed in 1 day and store equipment with a dry tank. The maximum shelf life of the finished mixture is 2 weeks, so more than 2 liters at a time it makes sense to mix only to utilities who cut the city lawns.
If you have not used a scythe for a long time, and there is gasoline in it, it is better to pour it out. The mixture has already been divided into fractions and lost its properties, even the most thorough mixing will not save it.
After making sure that the gas tank is in order, try to get a braid. For this you need:
- Switch fuel into the carburetor with a grain button 5-6 times.
- Close the air damper.
- Turn on the ignition on the handle.
- Pull the starter’s cord 1-7 times, until the launch.
- In 5.10 seconds disconnect the start system.
After downtime, if you can’t start the engine in the usual order, try to open the throttle and press the gas trigger. Without releasing the trigger, pull the starter cord.
A fully working trimmer for grass is started 1-2 times, even if the cord is calmly pulled, and not pull it as much as possible
It is also recommended to start a motor with a clamped gas handle if it has not yet cooled after the previous working cycle.
If the engine has not started on 5-7 jerks, it is worth looking for a breakdown.
Option. a problem in the ignition system
The first thing that suspicious falls is. the candle does not give out a spark, and therefore the fuel mixture does not ignite. Most often the problem is in the candle itself.
For verification, unscrew the spark plug from the cylinder, having previously disconnected the wire from it.
The thin layer of brown soot indicates the normal operation of the engine, red or pink soil. an abundance of fuel additives, change the gas station. If the element is covered with black or white scale, the engine worked incorrectly.
Wet candle indicates overflow, excessive pumping of fuel with a primer. In this case, the candle needs to be dried, but not to get. Pour excess gasoline from the cylinder, turning the motorcycle.
When cleaning, pay the greatest attention to that part of the upper electrode that is aimed at central contact, but do not zeal too much
Contacts of the dried candle should be cleaned of soot with the help of a suprafil, sandpaper or ladies’ file. The gap between them should be 0.7. 1 mm. this is the thickness of the standard coin. If necessary, bent the upper electrode.
Before assembly, it is worth checking the performance of the candle. Connect it to the power (put on the cap), attach the body to the cylinder or any metal part of the engine, turn on the ignition, pull the starter. At the end, between the electrodes, with each jerk, a bright, powerful spark should slip through.
It is very important to observe safety precautions. There should not be a drop of gasoline on the neck of the candle opening and the body of the motorcycle!
If after drying, cleaning and setting a sparking gap, buy a new candle. It happens that the spark does not appear on the new candle. In this case, check the quality of the contacts, try to replace the armored vehicle. this is inexpensive and simply.
If there is no spark with a new wire, you need to buy a new ignition coil. It happens that the cable is not disconnected from the coil, they are sold only in the collection. It is somewhat more difficult to replace it on your own, because you need to accurately set a gap of 0.25. 0.4 mm to the stemstone flywheel.
The normal gap corresponds to the thickness of the plastic bottle (cut a piece of measurement from it) or 4-5 layers of painting tape
Install a coil with a spacer, try on. Twist the starter: it must touch the spacers, but completely turn. Remove paper tape or plastic and finally collect the knot.
It happens that when checking, the candle gives out a small but stable spark, but the launch does not occur. After you tighten the candle into the cylinder, in a closed space, a weak spark may disappear. In such a situation, it is also worth replacing the coil: the new one will give out a more powerful impulse.
Option. you need to replace the filters
If there is a spark, but the braid for the grass is not started, the problem is most likely in the fuel supply. The easiest way to check the air and fuel filter. with this and start.
Testing their condition is quite simple: remove the filter elements and try to start the motor. If it turned out, you need replacement or at least cleaning.
The fuel filter can clog so much that its body will not be visible. Naturally, attempts to clean in this case are useless
Maxcut trimmer does not start hot
The gasoline trimmer for grass (sometimes the device is also called a gas station, motorcycle system) can fail for various reasons, for example, after the winter, if it is not for a long time. RIA Novosti, 29.09.2022
29 Sep. RIA Novosti. The gasoline trimmer for grass (sometimes the device is also called a gas station, a motorcycle system) can fail for various reasons, for example, after the winter, if it is not used for a long time. What to do if the trimmer does not start for the grass or stalls almost immediately after the launch, why the spark disappears in it, possible causes of malfunctions and ways to eliminate them. In the material of RIA Novosti.Trammers do not start with the help of a modern tool for mowing grass, you can quickly put the cottage and adjoining section in order. Trimmer for grass will help to carefully mow vegetation even in conditions of uneven relief. Such devices weigh relatively few, so their use and, if necessary, transportation will not be difficult. Depending on power, they can cope not only with grass, but also with shrubs.There are various types of trimmers to work on the site. Most often, the owners of country houses and cottages have to choose between gasoline and electric tools (the latter, in turn, are divided into those that work from the network and the battery). Each of these types has its advantages and disadvantages, and the final choice largely depends on what tasks will have to be solved with the help of the instrument to its owner.Many prefer gasoline trimmers. Then we will talk about possible malfunctions precisely in this version of the tool. As a rule, for regular mowing of the adjoining section, the power of a two.stroke engine will be enough.The causes of problems with launching breakdown a person risks colliding after the tool has not been used for a long time, for example, after storage during the winter months.To launch a trimmer for grass, it is necessary to carry out a number of manipulations, the rules of execution and the sequence of which are registered in the instructions for the tool. However, sometimes, even if the owner does everything right, the trimmer for the grass suddenly refuses to start up. The reasons for this can be very different: from the quality or shelf life of fuel to a malfunction of one or more parts in the engine.If there is no way to quickly give a trimmer for grass for repair, you can try to determine the cause of the malfunction yourself by checking the tool for the most common sources of problems.The engine malfunction to identify the cause of the problems that have arisen, the owner of the trimmer for the grass should check one after another check the key details of the engine of his tool. In many cases, you can determine the source of malfunctions yourself, without turning to the help of specialists.The malfunction of the hopper to verify the main nodes of the trimmer for the grass in search of possible causes of malfunctions, it is worth paying attention to the sapun. valve that helps to level the pressure in the engine. In fact, he passes the air necessary for its proper operation to the gas tank.Make sure that this detail was the cause of the malfunction, you can simple manipulations. To do this, it is enough to open the gas tank cover: if at the same time a characteristic sound is heard from a sharp absorption inside the air, it means that it is a saepun to suspect of problems with the launch of a trimmer for grass. By the way, this part can be carefully cleaned and returned to the place or replaced.Prisyl’s malfunction trimmer for grass refuses to start, pay attention to the state of the primer. The function of this part. Forced pumping fuel into the carburetor of the tool to quickly start a trimmer for grass with a cooled engine. It is a special button on the case, which must be pressed at the start of the launch.The idea that the root of the problem lies precisely in the work of the primer, the owner of the trimmer for the grass should lead to the fact that even after numerous attempts to launch the engine “on the cold”, a positive result can be achieved with great difficulty.Carburetan malfunction malfunction of the carburetor in the trimmer can hint several “symptoms” at once. For example, the engine is very difficult to start both in the “cold” and in a “hot” state or with great difficulty gaining the necessary speeds. At the same time, the carburetor will not necessarily be faulty; Perhaps it just needs to be adjusted.In order to determine what exactly caused the problems in the carburetor, it, as a rule, must be disassembled. However, this is not recommended to do this without the necessary knowledge and skills.A fault of the air damner drive is poorly started by a trimmer for grass with an unheated motor, the cause of the malfunction can lie in the improper operation of the air damper. If this part is faulty, then the engine can still be launched, however, at the same time, the transfer of the lever of the damper to the desired position does not give the expected effect.The function of such a damper. block the air supply at the right time, but if it holds well, the tool will not work properly. In this case, a faulty part will have to be replaced.Failure of the ignition system rule rule. Trimmeres ignition system includes three elements. The first (and main). This is the ignition coil. It consists of a core and several windings. The second element. This is the so.called flywheel on which several magnets are located. Third. The sparkling candle on which the necessary spark is formed in order to ignite the fuel.One of the most common malfunctions, due to which a trimmer for grass refuses to join in the work. This is a violation in the parameters of the gap between the magnets and the ignition coil. The indicator of 0.2 mm is considered optimal. For various reasons, this distance can increase, but the energy of the resulting spark, on the contrary, is noticeably reduced.The malfunction of the ignition coil itself can also lead to problems. You can check its performance in several ways, for example, by measuring the resistance indicators on it.Another source of possible malfunction may be the spark plug installed in the trimmer. You can evaluate the condition of such a candle without additional equipment, just twist it and carefully inspect the appearance and integrity of its contacts. The detail that was in the work is allowed by the appearance of a raid, but if it is black or white. So, the candle is not fully working. You need to check the gap of the candle, on average it should be 1 mm.The presence of problems may also indicate the fact that the candle was unscrewed from the ignition system turned out to be wet. In this case, the candle must first be dried in any permissible way and only then check whether it works or not.The quality is fuel that is worth doing if the trimmer for the grass for unknown reasons refuses to start. This is to check if there is a fuel in the gas tank. However, even if there is gasoline in the tank (provided that everything is in order with the tightness of the equipment, this liquid evaporates very slowly), there is no guarantee. that after a long break, it will be suitable for work.It is also important to remember that each type of engine in such tools makes its requirements for the quality and composition of the fuel. For example, for two.stroke engines, a mixture of gasoline and oil is used in proportions established by the manufacturer.In this case, in order to establish the work of the tool, low.quality fuel must be drained and replaced with fresh.Violation of the engine start.up procedure, despite the fact that the appropriate operating instructions should be attached to each device, many new trimmers new owners prefer to understand the principles of their work on their own, without printed “hints”. And sometimes make mistakes, because of which it is not possible to start the engine engine.Another no less likely option. After a long break in work, a person can simply forget the right procedure for the engine starting. So if there is a suspicion that the cause of the trimmer’s malfunction lies in this particular, it is worth it to re.read the instructions (or read it for the first time).A short circuit wire problems with the launch of a trimmer engine for grass may consist of faulty wiring. In the process of the tool or due to the low quality of the material that is used to isolate the wires, there may be a closure. Return the tool to work should help replace damaged sections of wires.Zasori in the air filter in the problems of a trimmer for grass can lead a blockage formed in an air filter. This may indicate a black plaque formed on the spark plug. However, even with a clogged filter, a trimmer for grass is often launched, but the tool can not fully work in such conditions and stalls quickly, and also noticeably loses in performance.You can make sure that the root of the problem lies in the air filter malfunction, if you try to launch a trimmer for grass without this filter (however, you should not operate the tool for a long time). If the naked eye shows that the filter clearly needs cleaning, the necessary manipulations must be carried out in accordance with the instructions attached to the tool. And if the filter change has not been made for a very long time, the part can simply be replaced.In the fuel filters, not only the air, but also the fuel filter of the grass trimmer, which is responsible for ensuring that a mixture of oil and gasoline is entered into the carburetor, can not only be a air filter. Trimmerers may face such a problem, who are not used to refuel the tool not very high.quality fuel or gasoline remained in the tank for a long time.Sometimes, even with such a problem, the engine of the lawn mower still starts, but it does not work for long and quickly stalls. If, after checking the condition of the filter, it turned out that it is clogged with dirt, the owner of the trimmer for the grass needs to think about its replacement.Violation of the tightness of the fuel hose is that the tightness of the fuel hoses is disturbed in the trimmer, a strong smell of gasoline that appears after the launch of the tool may indicate. If the appearance of these tubes clearly leaves much to be desired or, for example, they are too easily, almost without effort are disconnected from the primer, then they most likely require replacement.Diagnosis of a malfunction in the trimmer is far from always possible to determine at first glance. Sometimes in order to find source of the problem, it is necessary to conduct a thorough diagnosis. Here are some of the situations that the owners of the trimmer for the grass most often risk faced, and those reasons that theoretically can lead to them.It does not start “on a hot” obstacle in order to start a trimmer for grass with a warmed engine, a variety of circumstances can serve. For example, a filter clogged with dirt, clogged ventilation holes or a malfunction associated with the ignition coil. It is these elements in such a situation that must be checked first.It does not start “on a cold” wrong gap between the coil and the flywheel can also lead to the fact that the owner of the trimmer for the grass will encounter problems and when trying to start the engine “for cold”. In addition, it makes sense to check the air damper, primer or sapun.A similar problem can also arise if in the engine of the trimmer for grass insufficient compression.One fairly common situation is poor. Regardless of whether the engine warms up or not before starting, a trimmer is started for grass poorly or not starting at all. The cause of this situation can vary from poor quality of gasoline or its insufficient amount to a malfunction of a candle, a saopon or other details.The trimmer engine starts up and stalls immediately, but almost immediately, despite the efforts of the owner, begins to stall, the fuel that is in the gas tank should be the first to come under suspicion. Perhaps it is no longer suitable for work tools and requires replacement.A similar problem can also be provoked by a contaminated saopan or fuel filter, which also makes sense to check.There is a spark, and a candle of instruments can also encounter a situation with this situation: the engine of the lawn mower does not want to start, while the light of the ignition is dry (that is, excess fuel does not fall on it), and there is a spark on it. If this happens, you can check the integrity of the fuel hoses, as well as the serviceability of the filters and the carburetor.There is a spark, and the candle was spinning a similar situation, but provided that the spark plug suddenly turned out to be wet, the first thing that should come to the mind to the owner of the instrument. For some reason, a trimmer for the grass is too much gasoline or, conversely, in the combustion chamber. Too little air. The clogged filter, a malfunction of the air barrier or other elements of a trimmer for grass may be to blame for this.If a person does not have the opportunity to check the presence of a spark, then the reason is also to look for the problem in the possible malfunction of the candle itself. First of all, it needs to be dried. so that you can evaluate the visual state, and if there are doubts about its performance. replace.There is no spark of spark. The occasion to check the condition of the wires in the tool: it is possible that there was a closing and a button that turns on and off the trimmer for the grass simply does not work. Another possible reason for the lack of spark. This is a malfunction of the candle itself on which the spark should appear (for example, the gap has increased) or problems with the ignition unit.The rules for storage of trimmermarous Trimmer owners are faced with problems when starting after long.term storage of the tool, including. After the trimmer for the grass returned from wintering. That is why it is so important to observe the rules for storing the tool.Rule 1. Be sure to save the trimmer engine for grass from all fuel remnants, and clean the tool and place the tool in a dry room.Rule 2. If before you remove the tool for long.term storage, the owner found defects or malfunctions in it, it is better not to postpone the repair until spring and put everything in order in advance so that the problem does not aggravate.Rules for operating a trimmer.forward by how to start working with a new tool, the owner should carefully study the instructions attached to him. After all, even if a person holds in his hands not the first trimmer for the grass with which he has to deal with, it cannot be ruled out that it is this tool that will have certain features that it is important to consider and observe in the process of launch, work and storage.Sometimes in attempts to save time on the gas station, the owner of the trimmer for the grass prepares a large volume of the fuel mixture for the tool in advance. It is important to consider that it is not recommended to store such a mixture for a long time, since its quality suffers during long.term storage. And this, in turn, can negatively affect the work of the tool. Prepare the fuel mixture in accordance with the instructions.While working with the trimmer, you need to ensure that it does not overheat much. If this happens regularly, the tool risks faster to fail. Do not wait for individual details of the trimmer for the grass to clog so much that they will stop his work. Periodically, the tool needs to be inspected and checked.Expertable advice if a person has enough technical information and understands the device of trimmers, benzos and other similar tools, it is still not recommended to disassemble certain details (all the more complex). In case of failure, this threatens a more serious breakdown of the tool, even if the malfunction was very insignificant.Many tool owners are worried about how to work correctly a trimmer correctly. “We support maximum turnover (that is, full gas) and in this mode Kosim, while there is a need and strength. Says Alexey Shikhov, head of the service department of the company “E. Kobert” at the same time, it is not necessary. With such work, the main thing. Less idle. The mixture burns out (oil and gasoline) when you give more gas, and at the same time the piston remains clean ”.
As practice shows, gasoline trimmers for grass cease to start or function normally after winter, that is, long.term seasonal storage. Before subsequent attempts to launch the tool, a thorough diagnosis should be carried out in order to determine the source of problems. There are currently several of the most common causes of malfunction.
- Initially, it is necessary to check the quality of the fuel. Savings in such cases may have extremely negative consequences. Experienced owners of Motokos and experts advise preparing a mixture, the volume of which will correspond to the upcoming work, since its surpluses quickly lose their qualities.
- Trammers for grass of such eminent brands, such as, for example, Husgvarna, Makita, Stihl, are very sensitive to the fuel used. We are talking about fuel quality and octane number. Ensure suitable operating conditions and extend the life of the equipment will allow the refueling with high.quality gasoline.
- At the time of the launch of an internal combustion engine, the lawn mower can stall due to the fact that it floods the spark plug. Often in such situations you have to deal with the need to configure the carburetor. It is worth noting that similar problems arise when a braid for grass stops starting on a hot.
- Sometimes the tool cannot be launched, although the candle is wet, which in turn indicates the intake of the fuel mixture into the combustion chamber. As a rule, this is one of the symptoms that there is no spark. The reasons may be the absence of normal contact between candles and a high.voltage wire or drying out the threaded connection in the candle channel.
- If there are no problems with a spark, and at the same time the candle itself remains dry, then most often this indicates that gasoline is not downloaded. There may be several reasons in this situation. This, in particular, is about the state of the fuel filter and carburetor.
- ICE of braids for grass is not started or immediately after launch stops working, which can be due to clogging of an air filter that prevents the normal supply of air necessary to enrich the mixture.
In addition to all of the above, owners of trimmers have to deal with more serious troubles. One of these is the wear of the piston group. In such cases, to entrust professionals, which will significantly reduce expenses and extend the life of the tool.
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.
The second is a carburetor
It is not necessary to disassemble the node right away, especially if the engine stalls after starting or does not hold idle. First try to change fuel, maybe an excess of oil. You can inject the cleaner air filter, let the motor “laugh” a little at maximum speeds.
Next, go in order. the air filter, the fuel filter (it can be outside and in the tank), the fuel pump button, the integrity of the hoses. Gas tank plug. the ventilation valve can be clogged, the motor simply does not pump gasoline. Get everything. and will work!
Be sure to look at the connection of the carburetor with the intake manifold! Elsey there sucks air and there is no tightness. eliminate!
The dosing needle hangs. the problem is also in some models. It is enough to push it down, or remove and polish it with a velvet.
You can pull the hose from the carburetor, see if the fuel is coming to it when pumping. It is clear that you often need to remove plastic casing for verification, break your fingers on the latch, but still sooner or later you will have to climb there.
Where to start diagnostics motorcycles
If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main nodes and assemblies. The test algorithm is as follows:
These nodes are most often source of basic problems, which can be eliminated after a thorough inspection.
Check the fuel mixture
Before starting the engine of a gasoline braid for grass, check the presence, and the quality of the fuel mixture. Do not save, do not greedy and “do not smarter” in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil fuel mixture strictly according to the instructions. Calculate its number from real needs. Excess gasoline left after work loses its qualities over time.
We diagnose a candle and candle canal
If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be the reason. Here, a regular candle key is suitable for repair (every motorist has probably has a spare candle.
- We twist the candle and wipe;
- We thoroughly dry it (you should not bake it);
- Excess fuel in the chamber we drain through the candle hole and dry it;
- We clean the old candle from the carbon on a sugar or a ladies’ file;
- We set a gap with a distance of 1 mm (you can check with any coin);
- We return everything to place and try to start a trimmer for the grass.
Dry the channel at least 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.
If the working candle is working, the nest, where it is located completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly moisturized. No matter what wonderful spark gives out a candle, there is simply nothing to light up in a dry chamber.
The causes of breakdowns of gasoline and electric trimmers
Trimmer for grass, both electronic and gasoline engine (ICE), is a non.replacement inventory in the summer and autumn period for the owners of cottages and personal houses. With it, weeds, small bushes are removed without effort and the lawn is trimmed. But, as it doesn’t matter what kind of technique, trimmers for grass fail at the most inopportune moment. In order to remove the malfunctions with your own hands, the user of this technique is initially necessary to find the reason for their occurrence.
Fuel tank (fuel quality)
Remember that always before starting the unit requires a check of the presence and properties of fuel. In this case, do not skimp and save, also “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 substitution will cost about 70% of the total trimmer price for the grass. Pour combustible based on the fact that you will use it one hundred percent when performing work. The gasoline remaining in the tank after some time loses its characteristics and can harm the engine. Therefore, do not prepare the mixture for the future and in huge quantities. If the lawn mower starts poorly, try to drain the “old” fuel from the tank, and season it with a freshly prepared consistency.
If the compression is missing, then start the engine, almost always, will not work. To check the compression, you can use the car compressometer.
- Turn the candle from the ICE cylinder.
- Screw in its place a compressometer.
- Start pulling the launch cord because you do this when starting a lawn mower. Do this until the time the shooter on the measuring device does not move towards growth. This value will demonstrate the compression force of this motor.
What compression should be? Normally, the compression should be at least eight kg/cm 2. Although even at eight kg/cm, two certain engines do not have an idle and stall, because the fuel does not pump in a sufficient way. If your gas station does not pump above eight kg/cm two. you have to check the cylinder, piston and rings.
Also, bad compression can be due to a slightly adhered carburetor. Check if he is staggering. If so, then perfectly tighten the fasteners holding it. Also, if the carburetor is poorly screwed, you can see that gasoline is dripping during operation.
Malfunctions of electric trimmers
Since the device of an electric coser is much easier than a motirmer, then the circumstances of its failure is a little.
In the main thing, the trimmer for the grass ceases to work normally in subsequent cases:
- electronic cable malfunction;
- The control button is faulty;
- burned winding of the engine stator;
- Contact joints break on the engine.
This filter cleans the fuel of probable 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. To get to the filter, you need to extract a cork with tubes emerging from it.
Adjust hair clippers maximum power screw
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, in advance 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 stick the last one in the tank.
Candle and candle channel
So, you changed the fuel, but nothing has changed, and Trimmer for grass
it will not start anyway. In this case, it is worth checking the candle channel: whether it throws it with a combustible consistency. 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 impracticable. To diagnose and remove the probable case in this node, do the following.
- You need to turn out the spark plug, wipe it perfectly and dry it. When installing a candle in the ICE cylinder, it should be dry.
- Drain the combustion of the combustible fuel from the combustion chamber. This is done through the hole from which you turned the candle.
- In the presence of a carrier on the electrodes of a candle, it must be removed either with a narrow suprafil or a nail file.
- Do not forget to put the gap between its electrodes before installing the part in place. The gap on the candle should be equated one mm. As a probe to check the gap, you can use a coin.
- Next, collect the block, read the launch annotation and try to start the engine again.
If the engine does not start, then it will be necessary to check the spark. For this:
- turn out the candle;
- put on it a cap of a high.voltage wire;
- Touch its iron part to the cylinder body (to provide contact, you can stick a tubular key) as shown in the figure below;
- pull the launch cord so that several revolutions of the motor.
Normally, with each piston rolling between the electrodes of the candle, the spark should skip. If there is a spark, then the reason that the internal combustion engine is not launched should be found in other nodes of the device.
For the best awareness of the process, how to test the candle for the presence of a spark, you can use this. where the audit is shown on the example of the Lawn Mushiel “Soyuz”.
If there is no spark, then first check the cable connecting the candle with the coil. maybe cause
specifically in it. You can call it with a tester. If the circuit is detected, the high.voltage wire will need to be replaced.
Also, a prerequisite for the sparking can be a malfunction of the ignition coil (magneto). The figure below shows how the coil (magneto) looks 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, and specifically, its primary and secondary winding. On the primary winding, the resistance should be within the boundaries of 0.4 to 2.0 Ohms. If the device indicates zero, this means that the locking has become a closure, and if infinity is an obvious sign of a chain break. The resistance on the secondary winding should be within the boundaries of 6 to eight lumps.
If the trimmer for the grass does not start, we check the serviceability of the filters
You will need to resort to checking the air filter, through which the incoming air is cleaned into the carburetor. The clogging of the cleansing element leads to the fact that the air enters in a smaller quantity or its supply to the carburetor is completely stopped. Find out whether the air filter is the reason that the trimmer for the grass is not started is in a simple way:
- Remove the air filter and inspect it. The presence of clogging is already a reason to blame this detail in everything
- If there are no clogs visually, then you must try to start the motor without a filter. If a trimmer for grass starts without a filter, then it is definitely necessary to replace this part
- The air filter can be cleaned with a stream of compressed air, but if it has not changed for a long time, it is advisable to replace it with a new
It should be noted that a trimmer for grass can not start due to a blockage of an air filter, but these are extremely rare cases. Often, air filter clobs affect the stability of the engine, and also contribute to a decrease in performance.
It is interesting!If the chainsaw began without an air filter, then working as a tool without a filter element is contraindicated, since pollution will fall into the cylinder, and thereby the operational resource will decrease. The real reason why the gasoline trimmer for grass is not started is to clog the fuel filter. This part is located in the tank of the tool, and if the spit is already more than 2 years, then it is time to check the serviceability of the fuel element. If the filter is clogged, then the fuel mixture will not enter the carburetor accordingly, which means that the trimmer will not start the grass.
There are no difficulties with the replacement of the fuel filter, since for this it is enough to extract this part from the tank, and to replace it. If you are going to clean the fuel filter with a compressor, it is recommended to abandon this venture. It is better to buy a new filter for cleaning the fuel of the lawn mower, since clogs will still remain inside the old element. Below the video shows the process of replacing the fuel filter on the Oleo-Mac brand gasoline.
If you are not sure that the reason for the impossibility of launching a trimmer motor for grass is a cleansing element of fuel, then the following actions should be done:
- Remove the fuel filter
- Run the lawn mower
- If she got started, and quickly, then the problem is really in the fuel filter
The filter is clogged through the following reasons:
- With prolonged operation of the tool
- If low.quality gas or oil is used
- With prolonged storage of fuel in the tank of the tool
- If you pour fuel into the tank, which was stored for a long time
- When dust and small particles get into the tank of the tool. This usually happens during the tooling
It is interesting!If the fuel filter is working, and the lawn mower is not started, then it is worth making sure that the fuel hose is placed in the fuel. After all, there are times when the hose, along with the filter, is simply disconnected from the trunk tube, which leads to the impossibility of starting the engine engine.
Rules for the operation and storage of a lawn mower
In order for the lawn mower to start well and continue to provide it with good storage and operation conditions:
- During operation, carefully monitor the cooling system, carefully and in time, clean the channels in the case, as well as the ribs of the starter;
- If necessary, use solvents, kerosene and other detergents for cleaning;
- Do not clean the “hot” tool. let it cool;
- Stactly comply with the requirements of the instructions for the operating mode, otherwise you can overheat the engine;
- If you do not plan to use the lawn mower in the next month, the fuel mixture from it needs to be drained, t. to. Over time, it breaks up into heavy fractions, which will definitely clog the channels of the carburetor;
- After draining the fuel, let the trimmer work at idle until it stalls, this will help to completely remove the rest of the working mixture.
Before winter storage, take the following steps:
- completely disassemble the braid, rinse and clean all the details you can;
- Inspect the details for damage, if necessary, eliminate distortions, impulses, bent and any other malfunctions;
- Pour a sufficient amount of oil into the gearbox and clean the air filter;
- You can partially disassemble the motor, rinse, blow and smear all the moving parts;
- In order to lubricate the piston, you need to unscrew the candle, raise the piston with the outlet to the extreme dead point, pour a little oil into the candle hole and scroll the crankshaft a couple of times;
- If you store the lawn mower not in the house, wrap the engine with an oiled rag.
Remember, careful compliance with the rules will allow you to forget that the lawn mower is bad for several seasons.
When it is poorly started on a hot diesel engine
To chagrin, diesel engines also from time to time may not start on a hot. In most cases, the causes of this phenomenon are malfunctions of subsequent nodes:
- Cooling water sensor. Here the situation is similar to the one that was described in the last section. The sensor may fail and, accordingly, transmit incorrect information to the ECU.
- The crankshaft position sensor. Situation similar to an injector engine.
- Air mass flow sensor. Similarly.
- Fuel pump of the highest pressure. Namely, this can happen due to a significant wear of bushings and a pumping shaft of the pump. Air enters the pump from under the omentum, which is why it becomes impossible to collect working pressure in the prelunate chamber.
- Diesel engine.
- Fuel pressure regulator.
- Ignition module.
Now we will try to summarize the information given so that it is easier for you to find the cause of the breakdown if it happens to your car.
Checking the ignition by oscilloscope
What to do if the used fuel mixture is in perfect order, but as before it does not start Trimmer for grass
petrol? The prerequisites for the refusal of the mechanism can lie in excess moisturizing the candle channel. To diagnose and eliminate the task, you need to make the next:
- Turn the candle. Wipe it painstakingly, and then dry it.
- Drain the excess combustible in the chamber through the corresponding candle hole.
- Clean an old candle if there is a dozen on its surface. The use of an ordinary ladies’ nail file or a file will allow you to cope with the task.
- 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 multifunctional block back.
- Try to start a trimmer for grass.
The lawn mower is not started on hot
If the lawn mower was not so long ago in work and has not yet managed to cool but did not want to start. press the gas trigger, sharply pull the starter’s cord a couple of times until the engine is started and the gas trigger is released later. If quite a lot of time has passed and the lawn mower managed to cool, then you need start
As with cool. If the above methods did not help, the lawn mower did not start, then you should contact the service center.
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
Repair of the lawn mower. (changed, added).
So, dragged a benzo-cos, with symptoms: grasps but does not work.They pulled, her seals for about an hour. I say: Well, if, the maximum of the 5th time did not start, then the matter is clearly not in Babin, rather in the gasket.))).Sent deer behind beer. He said the repair price, they were compiled, although they twisted with nozzles for a long time))).
So. Disassembled. He made the Rotor’s shooter. Why do you need the Rotor’s shooter, but at least in order to remove the rotor normally. Those who write from “” Bat and nah shooter, I do not advise doing this: break the case, or the rotor will crack, bite the tsapfu or kill the tsapt carvings to death))).The procedure for detecting malfunctions in any benzoca or chainsaw:. check whether the spark is present. Should be strong and with smooth scrolling by the starter. If there is no spark, check the wires (on \ off), the candle itself and of course the short circuit itself. Often, due to broken bearings, the magnetic part of the coil sensor clings the rotor. When installing the ignition coil back, between the rotor and the coil magnet, put a piece of strip with a cut plastic bottle (to hold the gap), it should be in the rayon from 0.8 to 1 mm. But again, you need to look so that it does not catch the sensor. If even with a 1mm gap there is a shorting, then we change the bearings or the rotor itself (maybe a curve).Further, if the candle is constantly wet, this says that the carburetor shimmers! It is not advisable to climb into it (without knowledge). Everything is very fragile there and you can finally break firewood. It is better to replace with a new.
Do not start, grasps: often air leaks! We look at the intake pipe, he has it, almost from plastic! He is spinning over time, he cracks. Also pay attention to the integrity of the gasket, filter and the container itself, the case (there may be cracks).But the most common cause is the wear of the seals! It is not difficult to check: there will always be oil leak or finally everything in oil as in the photo above! You can check (whoever has a compressor) shut up the intake \ graduation channels to pass by spraying the seals with a soap solution and supply compressed air to the crankcase.You can change the oil seals without disassembling the housing, just lift the old special-hard-hardened or stiff bent wire.Do not score a new one, do not shove a screwdriver, or God forbid the sledgehammer. Having smeared the outer edge with a sealant with a slight effort, he must go. If we are tightly selected by the appropriate mandrel and with light blows in the area of the metal clip, we sit in the place.Well, since they removed it, it is advisable to check the backlash of the bearings.If you removed the crankshaft, it is also not cost.effective to change the bearings on it! Better to change everything assembly! And save your nerves and a mower)))).If the mower is weakly drawn (does not have a power), it is advisable to look into the piston. To remove the piston, you need a specification (long hexagonal screwdrivers).Look like that’s it. Who does not know what, we will not be shy.In the course of disassembly, a flaw was revealed, namely a broken oil seal (punched through).The seals were replaced. Installed on additional sealant (window, very expensive and reliable). All gaskets are replaced.All threaded joints “sat down” on anaerobic sealant (Loquetay is popularly) blue.Everything was adjusted and wound up.And people already wanted to throw out))).Do not lose hope))).Good luck and good.
The lawn mower stall when you press the gas, how to eliminate the breakdown
The reasons why the lawn mower stalls is a huge number, we offer the most common of them, and we hope that you will find your own, and, of course, eliminate it. So, one of the situations is to clog the air damper, then the hole behind which the fuel is sprayed. If something got into it, then it can most often be quickly and easy to remove. This is the simplest reason, like a clogged filter. It needs to be washed in the solvent, and then get it well with compressed air. If it is not subject to repair, then order a new one in spare parts from the Kosikos store.
Similarly, when you press the gas, the tool stalls because the drive has clogged. The following option is possible: the fuel does not come in full, so you need to check or replace the fuel filter. To other possible reasons, the stalled motorcycles, when you give gas, should be attributed:
To all these reasons for which the mechanism stalls when adding gas, we will add several useful recommendations for the treatment of a motorcycle. First of all, before starting working with any equipment, you need to read the instructions. In this case, an important role is played by the consistency of gasoline and oil, correctly prepared by you, and also not to overheat the unit, and not leave gasoline for the winter when you simply will not use the machine.
In the full work of any tool, an important role is played by the coordinated work of all its components. And if in one it is a fishing line for a trimmer for motorcycles, then in the other a piston or carburetor. Motokos owners who want to use their tools at full power, you need to understand that the load on which the capacity of the machine is not designed may simply break the entire mechanism or its individual parts. Therefore, only competent and moderate operation involves the long.term effective work of any benchmate tool.

The trimmer stalls for grass at idle. the causes and their solutions
To common situations why a trimmer for grass or a lawn mower stalls, it should be attributed to its work at idle. Let’s immediately move on to the reasons:
- heating the gearbox and sleeping on the drum as a result of the fact that the gasoline solution is not prepared correctly. The required proportion is 1: 4;
- carburetor pollution;
- The throttle flashed;
- When opening the damper (if the experiment was carried out), the air flow makes a mixture of the “poor”;
- Ringing the carburetor;
- clogging of the air filter;
The insufficient amount of fuel that you need to work as a gas tool will entail a situation when at high speeds, with an increase. a trimmer for grass works and stalls in idle. In a situation with a carburetor. the device will stall for a cold launch and “on hot”. For any user, Motokosa. Professional and Amator, it is important to understand that any tool problem can depend on the petty flying of the part, the release of fastening or clogging, as well as on the global breakdown of the important part of the mechanism.
Despite all kinds of problems, your device, nevertheless, needs such an obligatory component as knives for motorcycle, without which the exploitation of braids for grass is simply impossible!
When opening an air damper
It happens that the unit stalls when opening an air damper, working normally at idle. This is due to the air leaks of the system caused by the presence of fuel hose cracks or problems with the oil seals. The carburetor dosing system can also work malfunctioning, while the lawn mower will stop after the opening of the damper.
All possible reasons that the lawn mower stalls, and the methods of eliminating them are contained in the next video
There are many reasons for stopping Motokos, but the most commonly occur in work related to its carburetor. They can arise in any case. The most problematic option is when there is a serious breakdown, and you will need to purchase new parts or change the lawn mower.
So that the trimmer for the grass works normally for a long time, you should strictly comply with the requirements of the operating instructions. It is necessary to refuel the unit suitable for it in the composition with a fuel mixture, the device should work with a moderate load.
