The GAMPION lawners do not start the reasons. Why is a trimmer not starting for grass gasoline? Reasons and their elimination
Diagnosis of the reasons why the lawn mower is not started. A quick return to the life of Chinese and domestic motorcycles with a two.stroke internal combustion engine. It happens that a two.stroke motor does not even show flashes in the cylinder, but it happens. grabs, and then stalls. Do not be sad, this Chinese consumer goods can be repaired directly on the knee using a minimum of tools.
Before starting diagnostics, you need to make sure that the engine rotates with a slight resistance. If there is no compression in it, then the further is useless, and you need to change the piston (this is also nothing complicated, everything is as a designer).
The first is a candle
First of all, you need to unscrew the candle. If it is wet, then the ignition system is faulty. Try wipe the candle, put it in the cap, attach it to the engine, pull the starter. There is a spark? If not, then you need to change the candle.
Replacing the candle did not help? Then you need to watch magneto, cable, ignition coil. The cable is nicknamed, the coil is checked for resistance (multimeter in the resistance measurement mode of 200 Ohms, one contact for the mass, the other to the reel exit should show from 0.4 to 2 ohms).
Sometimes magnets are polluted on the flywheel, or the key is lung, and the ignition moment flies up. Chinese shit throws various surprises, but for the most part everything can be identified visually.
Be sure to pay attention to the coat of candles. If it is black, the candle is smoked, then the mixture is rich, or you mixed the fuel incorrectly. If the plaque is white, then the mixture is poor, and the engine could already die from the temperature. Ideally, the color should be brick, bright, without much raid.
Again, if the black candle is dead, you should not immediately sin on the carburetor and ignition. Plunge the new, see what plaque will be. Maybe just a candle was poor.quality.
Why and what to do if a gasoline trimmer for grass does not start
If a benzotrimmer does not start, the breakdown can be caused by several reasons. Most often, the failure occurs:
- due to clogging of air or fuel filters;
- because of the exhausted old gasoline in the tank;
- due to damage to the fuel hoses;
- due to damage to the ignition system;
- due to a short circuit of the wires responsible for inclusion.
Also, the launch of the primer and the saapon, the clogging of the carburetor and the air damper drive clogged.
The most difficult thing is to repair a benzotrimer with a malfunction of the engine, but such a breakdown is rare
Exhausted gasoline in the tank
Many trimmers left fuel in the tank after using the unit. If the cover is not closed not, gasoline can exhale and absorb moisture from the air. As a result, the combination of the mixture is reduced, and the motor does not start.
It is very simple to fix the situation. you need to remove old fuel from a gasoline trimmer for grass. Do it like this:
- Pump up new gasoline primer.
- Twist the starter cable many times.
- Pump the old fuel through the combustion chamber until the tank is empty.
- Dry the candle.
You can also simply remove and disassemble the carburetor to drain the remnants of exhausted gasoline. But it is more difficult to do this, you must have minimal ideas about the device of a trimmer for grass that does not start.
A short circuit of wires
The wires suitable for the engine are responsible for the engine. they are connected by the switch, and as a result, the gasoline trimmer for the grass is launched. Due to poor-quality isolation or permanent vibrations, the cables can be wiped out.
If a short circuit occurs, the engine is not started by pressing the button. You can eliminate the problem according to this scheme:
- The wire departing from the start button is removed from the terminal terminal of the ignition system.
- Using the tester, check the cable resistance in “Inclusive” and “off” modes.
- If there is a malfunction, a working handle of a gasoline trimmer for grass is disassembled.
- Cut or solder suitable to the motor, ignition system and wire button.
- Extract the remains of cables and set new in their place.
- Collect the hilt back.
If the gasoline trimmer for the grass starts again, the repair was successful.
Attention! In good wiring during testing in “inclusive” mode should give resistance striving for infinity.
Flowing the air filter
If the trimmer for the grass has not stalled and does not start, the problem may consist in clogging an air filter. To diagnose a breakdown, you need to extract a candle from the unit case and inspect it. If there is clogging, it will be black.
To eliminate the problem, you need to disassemble the motorcycle and pull out the filter from the body. It is cleaned in accordance with the instructions for a specific trimmer for grass, and then set to place. To prevent the problem, it is recommended to conduct preventive maintenance of equipment from time to time.
Falf in the spark plug
If the benzotrimer does not start, the failure can be caused by a candle breakdown. Diagnosis is carried out as follows:
- Twist the element from the cylinder block head.
- Carefully examine. if the contacts of the candle will be covered with a malfunction, will be covered with a black coating.
- Soak the part in vinegar solution 20% for half an hour to clean.
- Sprinkled with soda and washed with water after another 30 minutes.
- Dry with compressed air and installed in place.
In some cases, after cleaning, the candle comes into an efficient state, and the gasoline trimmer for the grass starts again. If this does not happen, you need to replace the element with a new.
If a black fog quickly appears on the new candle, the problem may consist in re.enriched fuel
The ignition coil malfunction
If the trimmer for the grass is jerking off and does not start, it is worth checking the ignition coil. Do this as follows:
- All wires turn off the block and remove them from the candle.
- Measure the resistance of both coils-in the primary it should be 2-3 Ohms, in the secondary 4.5-5.5 ohms.
- With a strong deviation of the indicators, the ignition unit is replaced with a new.
You can check the knot in another way. Instead of a candle, the tip of the discharge is inserted into the appropriate wire and the latter is connected to the motor. Then you need to set a gap with a size of 0.5-0.8 mm and twitch the starter cable. The ignition unit requires replacement in the absence of a spark, but if it is, then the malfunction lies in the candle.
Recommendations and preventive measures
It is quite difficult to start a benzotrimer with malfunctions, sometimes repair requires a lot of costs and applies of efforts. Avoid breakdowns allows compliance with prevention rules. In particular, it is recommended:
- Timely clean the ribs of the starter and channels on the housing of a gasoline trimmer for the grass;
- Before a break in the operation of the unit, drain the remaining fuel from it;
- After cleaning the gas tank, start the engine at idle to eliminate the last traces of the mixture;
- use only high.quality fuel when operating the unit;
- load a gasoline braid in accordance with the instructions;
- Before cleaning for storage, disassemble and thoroughly rinse the trimmer for grass with solvents.
It is recommended from time to time to subject the gasoline braid to be careful to identify mechanical defects. Regular preventive cleaning requires air and fuel filters of the system.
Attention! Before cleaning the gasoline trimmer for storage grass, you need to lubricate the piston group with motor oil.
The more intensively the benzotrimmer is used, the more often its individual working nodes clog
Check the filter
Another common reason why there is no starting trimmer for grass
The presence of clogging in the filter area. To confirm the assumption, it is enough to dismantle the indicated block and try to launch the device without it. If the trimmer engine starts up, you will most likely have to replace the air filter or at least carefully clean the old. If there is strong contamination on the surface of the filter element, you must use a new grid. Do not leave a suction pipe completely without a filter. Indeed, a rush in this case can lead to the need to repair the entire piston group of the engine.
Types of launching a lawn mower
What needs to be done first? Click on the gas lever and the corresponding trigger to install the throttle in the starting position. Then press the start button. Let the gas clamp, the gas trigger and the start button. Thus, we activated the throttle function. To return the engine to idle, it is necessary to press the gas clamp and the gas trigger again.
Pay attention to the fact that you can not press the gas trigger before the engine starts and starts to work.
- We have the tool on a flat surface and slowly press the fuel pump button up to 10 times, the number may vary depending on the model.
- Then we install the lever of the launch system switch to the Start position.
- It is necessary to sharply pull the starter’s cord until the engine starts.
- Let the power unit work for 5-10 seconds and then press the throttle trigger to disable the starting system.
- We hold the throttle trigger in a pressed position and do not let go until the engine works evenly.
- We pull the starter’s cord abruptly and wait until the power unit starts. The trigger in this case should be pressed.
- The launch of a warm engine is carried out within 10 minutes after it stops. If more time has passed, then use the instructions for turning on the cold unit.
Starting the engine with a “flooded” spark plug
In this case, the power unit can be launched if you install the launch lever to the RUN position, the throttle trigger must be pressed. Then we pull the starter handle as many times as required to start the engine. If the power unit does not start for a long time, you should seek help from the service center.
Cycle: why the piston may not move inside the cylinder
The flywheel of a trimmer for grass, aka Magneto’s rotor with magnets, is fixed on the shaft with a key.
This is usually a reliable connection. Under the flywheel there is a sealing oil seal that does not pass the oil from the crankcase out. But when he wears out, the craftsmen have to remove the flywheel and change the oil seal with a new.
Otherwise, the oil flies everything, including the air filter.
At the same time, it is not so easy to remove the key: people make special pullers.
When looking for information on trimmers, I came across a video of one master, who was brought into the repair of the lawn mower, where the flywheel gap was absent. Perhaps a factory marriage. Naturally, such a motor will not start.
A similar reason should also be borne in mind.
Cycle: malfunctions of the sparkling spark
Когда поршень достиг верхней мертвой точки и сжал правильно подготовленную рабочую смесь вместе с воздухом, то ее поджигает электрическая искра, проскакивающая между контактами свечи.
Iskra is a category of electric current among gases. He must have a certain force and power. Weak spark of candles is not able to ignite the fuel mixture.
The causes of a bad spark should be sought in the electrical and kinematic scheme of its formation. magneto. This is the name of a device that transforms the mechanical energy of rotation of the shaft into a spark: current discharge.
Trimmers for grass and chainsaws are now supplied with a contactless electrical circuit of Magneto: it creates less problems in operation than a system with an interrupt. With her, the gas outlet starts more reliable,
- flywheel or rotor magneto with built.in constant magnets;
- high.voltage coil with wires and electronic circuit;
- spark plug.
During the repair, it must be borne in mind that the electrical electronics and candle design details can differ in various parts of the electronics, although manufacturers try to unify and standardize them.
The following picture will help to understand the principle of their work.
The constant magnetic field of the rotor rotates next to the high.voltage coil having control windings, power and charger. Each of them introduces its own electromotive force, which is the source of energy of electricity.
The output winding of the high.voltage transformer, running electronics, gives out the pulses of the discharge current to the spark plug, between the contacts of which the spark rides.
I used to see an old specialized device for checking the spark plugs in a sealed transparent case. Inside the unit, a pressure was created, a screwed candle was connected to an electrical circuit and checked on a spark.
However, each owner can check the power of a spark and the operation of a candle with a sparkling coil right on the trimmer:
- The candle is twisted with a candle key from the cylinder block;
- A high.voltage wire with a dielectric tip needs to be connected to the candle head. we restore the contact contact of the output winding of the transformer;
- The metal part of the candle body is laid on the cylinder block. You can use a conductive conductor. the same candle key. Only it cannot be inserted into the cylinder: you can damage the piston head;
- with a free hand it is necessary to pull evenly, but not pull, the starter cord. Visually observe the state of the spark on the contacts of the candle.
- contacts of the spark plug and the state of its insulation;
- the integrity of the high.voltage wire;
- serviceability of a high.voltage coil;
- the degree of wear of the permanent magnets of the flywheel;
- air gap between the flywheel and the ignition coil.
If the spark is weak or absent, then most often the causes of the malfunction lie in contaminated contacts or violation of the factory clearance of the candle. Other factors appear less.
When purchasing a trimmer for the grass, you need to take care of the reserve candle of the same brand. She, like spare parts, is needed when the motor does not start.
I recorded the brand my factory candle: l7t. You can use counterparts in case of breakdowns or damage when repair is required.
The candle gap of the non-contact ignition of the trimmer for the grass should be maintained in the interval of 0.7-0.8 mm. When examining and diagnostics, I recommend cleaning the contact electrodes from the carbon. Voronilo will help. a type of fine.grained file.
It is necessary to take into account the causes of malfunctions of the high.voltage coil and insulation of the wire. But they happen less often than that of a candle. If you noticed cracks, cuts, damage to the insulating layer, then wrap it with electrical signs, put on a heat shrink, or preferably replace it completely.
Magneto’s most overstated air gap can also be greatly affected by the lawn mowed. When it does not start, it should be reduced on its own to 0.2 mm.
This question clearly explains the owner of the video repair Nick TV in his video “A lawn mower or chainsaw, first prevention” is poorly started “. I recommend to see.
If you look at the lower part of the ignition coil, then a rectangular metal plate is visible in the middle.
It should be located on the central line of Magneto. Displacement forward or backward: it will be early or later ignition. The best performance is in the center. Seek minimal deviations. The settings are simple.
The trimmer for champion grass is poorly started
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 ”.
Dry and wet candle what it means and how affects the launch of the motor
Most of the owners of the tools immediately resort to checking the state of contacts of the spark plug. This is done in order to understand, by the state of the candle, what could be the reason for the impossibility of starting the engine of the lawn mower. According to the state of the candle contacts, you can draw the appropriate conclusions about what can be the cause of the malfunction. Diagnosis of the spark plug on the trimmer is performed in the following order:
- The spark plug unscrews, after which it is subject to inspection. The ideal state of the electrodes. if they have a brown carpet (brick color). If the candle is wet, has a black or white fog, then this indicates the corresponding faults
- If the candle is wet, then in the combustion chamber there is a portion of unbroken fuel, which does not need to be drained. Clean and dry the contacts of the spark plugs, then make sure of its serviceability. To do this, connect it to the immunity, and place it not the surface of the cylinder. Turn on the ignition and pull the starter handle easily. In this case, the candle should issue a quality and constant spark. If the spark is weak or it is not at all, then the spark plug should be replaced
- A trimmer does not start for grass may not be started due to a large gap between the contacts of the candle. The gap between the electrodes of the spark plug should be in the range from 0.7 to 1 mm. Special probes are used to set the gap
It is interesting!Dry candle contacts by pumping it is strictly contraindicated, since this method will lead to damage to the details. If there is a spark on the candle, but the trimmer for the grass does not start, then the reason is the supply of the fuel mixture in the combustion chamber. To make sure this, you should perform the following actions:
- Dial in a cap made of PET bucks or in a syringe of 20 grams of fuel
- Pour it into the combustion chamber through the candle hole
- Twist the spark plug
- Put on a candlestick and start the engine
If the engine of the lawn mower starts after the actions performed, then the cause of the malfunction should be sought directly in the fuel line and carburetor. If the motor does not start even after the actions done, then you need to check the serviceability of the high.voltage wire. The high.voltage wire, like the spark plug, refers to consumables. If there are suspicions of a malfunction of the armor of the trimmer for the grass, then it should be replaced. If, after the actions done, it is not possible to launch the engine of the lawn mower, then the following recommendations must be taken into account:
- If there are doubts about the serviceability of the spark plug and high.voltage wire, then it is recommended to immediately replace them
- Check the serviceability of sparking, and if there is no spark on the new candle, then the breakdown is associated with the ignition unit. the failure of the coil is out of order
- The ignition coil is not repaired, but changes. If the diagnosis really indicates a malfunction of the ignition of the lawn mower, then it is not difficult to replace it with your own hands
If there is a candle on the spark, and at the same time it is dry, and the trimmer for the grass does not want to start, then we move on to check the next node. air and fuel filters.
It is interesting!If the candle electrodes have a red or pink color, then this suggests that the composition of the fuel used contains a large number of additives. You should abandon such fuel by changing a gas station or a brand of gasoline.
The most frequent malfunctions of gasoline lawners
It is necessary to check the fuel. It is possible that due to its absence, the engine will not start. The reason for the refusal of the engine may be a candle. The car is removed and the engine is launched again.
Силовой агрегат завелся, но сразу заглох
The reason for the refusal of work may be an insufficient amount of oil in the motor crankcase. Because of this, the piston or crankshaft often jams. Try to hand it manually. Often such actions give a positive result. Then, before repeated start, it is necessary to add the missing oil.
To revive the unit, it may be enough only to pump up fuel with a plain in a carburetor. The speed adjustment to the maximum will help. Then pull the cord smoothly on yourself. Twenty centimeters will be enough and a sharp jerk jerk over yourself.
Often problems arise With improper location of the air damper
, when the first trial start of the motor is produced. It is recommended to completely open the damper.
can serve as an air filter. It is necessary to disconnect the wire from the spark plug on the disconnected lawn mower. Then remove the filter, having previously unscrewed the lid. Rinse it with gasoline and dry it. Put in place, carry out re.launch of the motor. If the actions are unsuccessful, replace the old filter with a new.
We remind you. the planned replacement of the air filter is carried out after 25 hours of operation of the equipment. If the lawn mower works on the battery, you need to check the level of its charging.

Before you start repairing, study the instructions that must be in the kit to correctly diagnose
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
