Why the trimmer for the grass does not start: the causes of the malfunction and ways to eliminate them
Often, owners of gasoline cos are faced with the fact that ignition does not work on their technique. In most cases, the problem is really in this node. To fix it, you need to adjust the ignition on the trimmer. But at the same time, there are frequent cases that the ignition coil is working and a breakdown should be sought elsewhere. The ignition system is arranged equally on four.stroke and two.stroke internal combustion engines, therefore, the correction of the malfunctions of this node is carried out in a similar way. In addition, the technique of different brands has an almost identical design of this most important component of the tool, which means that the process of adjustment will be identical for both the trimmers “Soyuz” or “Prostr”, and for Huter or samples of other brands.
Many trimmers owners are faced with a problem when the device simply does not start.
One of the reasons for this may be the lack of a spark. This usually happens when the fuel floods the light of the ignition. In addition, you need to check the candles for serviceability, as this can also lead to a lack of spark.
The first sign of a faulty candle is the presence of a short circuit between its contacts, and in short. there is no spark on the trimmer.
In addition, the candle is considered faulty if it is covered with a black wet layer.
Such a layer appears from the oil combustion chamber. In such a situation, you have two exits: either clean the candle as it should, or buy a new.
Sometimes it happens that the candles are clean, but at the same time, the problem can be in its isolation, which is often covered with a black dry soot.
The reason for this may be a weak spark, excessively low spark plug, low fuel quality, dirty air filter or prolonged work at idle.
Here the output is the same. clean the candle or replace it with a new. over, the candle should be replaced if the contacts are strongly worn out.
In the case when there is no spark on the trimmer, how to solve the problem you will be told by professionals for a hundred.
Sometimes, the problem can be with magneto. Magneto may become unusable due to the fact that you could pull the starter cord at the moment when the ignition was turned off, and the candle was not grounded for the mass.
Such actions can easily disable magneto. In such a situation, the only way out is to buy a new magneto.
In addition, the problem may be the ignition node. This option can be considered if the candle and wire do not have any malfunctions.
In such a situation, it is necessary to engage in the replacement of the ignition unit. It can be found attached using two screws to the engine cylinder.
To obtain free access to the node, it is necessary to remove the enclosing casing.
To correct the current situation, you will have to replace the entire node, because, as practice has shown, replacing individual parts gives insufficient result.
If there is no spark on the trimmer, it can only be fixed in one way. replace it.
over, sometimes the problem should be sought in the ignition coil. The absence of a spark can lead to the failure of the coil or a malfunction in the chain.
To check the flow of current into the primary winding of the coil, you can use the light bulb, which must be turned on instead of the coil.
Then you need to carefully examine the contacts of the interrupter. If a strong spark occurs at the time of opening between the contacts, you can be sure that the capacitor is broken.
In this case, you have only one option of further actions. replacing the capacitor.
These are the main reasons why there may be no spark on the trimmer.
About the chainsaw and its inoperability
ATTENTION! A completely simple way to reduce fuel consumption was found! Do not believe? Auto mechanic with 15 years of experience also did not believe until he tried. And now he saves on gasoline 35,000 per year!
Chainsaw. installation in itself is not so complicated. But having the smallest initial knowledge is extremely important to find and eliminate any defect.
Modern electronics were so progressed that it also revolutioned in the world of tools. The saws of our days are light and powerful at the same time, equipped with electronic ignition systems of the ESZ.
Not so long ago, the ignition systems drank cam. This carried a lot of shortcomings: severity, complexity, high cost and much more. And the most important drawback of the archaic ignition system is the difficulty of the plant. Some of the systems of models of saws could not work out a spark sufficient for the outbreak at the speed of rotation of the crankshaft.
Modern systems are almost reliable. The models saw light and strong, the coil is made more professionally and serves its term almost without fail. However, there are also problems, but in most cases they can be fixed on their own.
Consider the main types of chainsaw malfunctions associated with the flywheel and ignition system.
As a rule, the most common ailment of modern chainsaws, implies the lack of a supply spark. The same directly depends on the shift of the lumen (clearance) between Babina and the flywheel.
Common malfunctions of installations are always connected with ICE. Problems arise in the system of ignition of fuel, the fuel flow module, in the internal elements of the engine itself.
As for the other nodes of the chainsaw, the malfunctions there, as a rule, due to the failures of the brake mechanism, poor lubrication, etc.D.
If the difficulties of starting are associated with the engine, then the symptoms are most often observed:
The inoperability of SZ chainsaws is the most common reason due to which the engine engine does not start. In most cases, it is recommended to start searching for a problem from here.
- First of all, thoroughly check the spark plug, gently throwing the armored wire from the head and twisting the candle from the nest using a special key;
- The second is a check of the sparking using the starter twitching with a cap of the armor pipeline on a candle;
- Checking the gap is the main theme of our article (more below).
So, the malfunction of the spark plug will clearly be evidenced by its sputum. A wet spark device for ignition of the fuel-air mixture suggests that the fuel is an excess of fuel, the carburetor is incorrectly configured or there are malfunctions in SZ.
The candle is checked only after drying. T.e., It must be carefully cleaned with a napkin, drain the insides of the internal combustion engine, clog the feed, and then start a couple of times a starter so that the excess of the combustible mixture comes out.
Then the spark device is put in place, and everything is checked again.
In general, the spark device can tell a lot about the entire ignition system. If a black fog is observed on the candle, this indicates violations in the communications of the gasoline mixture. Here, either the ratio of gasoline and oil was violated, or the carburetor is required to reconfigure. In some cases, this happens due to poor.quality oil.
A dirty candle is cleaned of a black carbon fiber with a needle or any other sharp object. Then, the electrode is cleaned with sandpaper (zero), until a metallic shine appears. The spark device is returned to the place, everything is checked again.
Next stage: checking sparking. The skirt of the spark device is brought to the cylinder, the starter starts. If a bluish spark slips at a distance of 2-3 mm, everything is fine. The sparking distance of 0.5-1 mm is already considered as a malfunction. There may not be sparks at all, and this is also a big problem. Perhaps this is the case of a cliff of the wire.
And so we approached the topic of our article. The chainsaw may not be launched due to a violation of the gap between the ignition and the Magneto flywheel. This very gap should be within 0.2 mm. It is checked very simply: a special gasket is placed between the flywheel and Babina. If it comes normally, not too free and tight, then the gap is normal.
The flywheel himself drank is round, and checking the gap with an ordinary probe is impossible. It would be more qualified to put a gap according to a special show, but it is not always possible to purchase. Yes, and not everyone can afford to buy a template that is not cheap.
However, in return for the foreign template, you can use a cut strip from a plastic container per 1-2 liters from under the juice.
Check the filter
Another common reason why there is no starting trimmer for grass
Brush Cutter Weed Wacker Weed Eater Edger Lawn Tool | Gardening and Lawn Tools #shorts
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.
Why is the ignition adjustment
In some cases, when the engine does not start, the ignition adjustment will be required. Of course, first you need to check the serviceability of a candle and a high.voltage cable with a cap.
It is necessary to adjust the ignition on a two.stroke engine in order to ensure timely ignition of fuel in the engine combustion chamber. Below is a scheme from which you can understand the principle of operation of the internal combustion engine.
The spark in the candle should appear at the time of compression of the fuel with a piston, when it does not reach the upper dead point (VMT) at least a little. Когда поршень проходит ВМТ, происходит возгорание топливной смеси, в результате чего поршень под действием энергии взрыва уходит вниз.
Therefore, if for some reason (mainly this is due to the shift of the flywheel to the shaft relative to its original position), the fuel fire occurs earlier than the piston passes, then it returns back, and the crankshaft scrolls in the opposite direction. Such a movement can damage the starter knot, cut off the launch cord, etc.D. In this case, an early ignition of fuel occurs.
There may also be a later ignition on the trimmer: the piston after compression of the fuel, which does not ignite, goes down, and at that moment a spark appears. In this case, the engine will either not start or significantly lose power and will be poorly gaining momentum.
But such problems with early or late ignition on two.stroke ICE are quite rare, since the flywheel with magnets is already established in the correct position, which is perfectly synchronized with the movement of the piston. In addition, the flywheel is fixed on the shaft using a key and nut. Therefore, the wrong installation of the part is excluded.
Basically, the ignition adjustment is to set the correct clearance between Magneto and the flywheel.
No spark on the trimmer |
Many trimmers owners are faced with a problem when the device simply does not start. One of the reasons for this may be the lack of a spark. This usually happens when the fuel floods the light of the ignition. In addition, you need to check the candles for serviceability, as this can also lead to a lack of spark.
The first sign of a faulty candle is the presence of a short circuit between its contacts, and in short. there is no spark on the trimmer. In addition, the candle is considered faulty if it is covered with a black wet layer.
Such a layer appears from the oil combustion chamber. In such a situation, you have two exits: either clean the candle as it should, or buy a new. Sometimes it happens that the candles are clean, but at the same time, the problem can be in its isolation, which is often covered with a black dry soot. The reason for this may be a weak spark, excessively low spark plug, low fuel quality, dirty air filter or prolonged work at idle. Here the output is the same. clean the candle or replace it with a new. over, the candle should be replaced if the contacts are strongly worn out.
In the case when there is no spark on the trimmer, how to solve the problem you will be told by professionals for a hundred. Sometimes, the problem can be with magneto. Magneto may become unusable due to the fact that you could pull the starter cord at the moment when the ignition was turned off, and the candle was not grounded for the mass. Such actions can easily disable magneto. In such a situation, the only way out is to buy a new magneto.
In addition, the problem may be the ignition node. This option can be considered if the candle and wire do not have any malfunctions. In such a situation, it is necessary to engage in the replacement of the ignition unit. It can be found attached using two screws to the engine cylinder. To obtain free access to the node, it is necessary to remove the enclosing casing. To correct the current situation, you will have to replace the entire node, because, as practice has shown, replacing individual parts gives insufficient result.

over, sometimes the problem should be sought in the ignition coil. The absence of a spark can lead to the failure of the coil or a malfunction in the chain. To check the flow of current into the primary winding of the coil, you can use the light bulb, which must be turned on instead of the coil. Then you need to carefully examine the contacts of the interrupter. If a strong spark occurs at the time of opening between the contacts, you can be sure that the capacitor is broken. In this case, you have only one option of further actions. replacing the capacitor.
These are the main reasons why there may be no spark on the trimmer.
Fuel pouring through the openings for candles
If there is no manual pumping on the engine of the trimmer for the grass and the device did not start, pour a little fuel into the motor itself through candle moves. Make the following.
- Check if the fuel level is sufficient in the tank for draining a small amount of it. It takes only 20 ml.
- Remove the cap from the candle and unscrew it with a candle key.
- If the candle is polluted on the former use of the trimmer, rinse and buy it. There should not be any deposits on the electrodes of the candle. Do not damage the ceramic insulator of the central conductor. In the new trimmer, check the candles for the factory defect.
- Return the candle back and check the spark look (category between electrodes) when the starter triggers.
- Remove the candle again. Using a 20- or 50-cup syringe, pour 20 ml of gasoline into a candle hole from under a candle.
- Insert and fix the candle by setting the magnitude of its technological clearance at least and no more than a millimeter.
- Skip fuel using a button (or lever) of swinging. if it is on your model of a trimmer for grass. Press the button every 4 seconds.
Now try to start the motor. Close the air conditioning immediately after starting.
Checking the ignition system
If the trimmer for the grass has already been used, then check the serviceability of the removed (at the moment) candles, changing it places with any other. If, when examining a candle, for example, a ceramic dielectric crumbled, electrodes bent. buy exactly the same, focusing on the product code, knocked out on the parts itself and checked it with a marker in the operating manual of a trimmer for grass. A candle without an insulator and/or with bent electrodes will not give normal sparks when triggered.
If the candles are in order, but the fuel is not observed, check the ignition coil using an ohmmeter (multimeter). Lack of indications (infinite resistance). a sign of a shift in the winding. If it was spent on overheating due to inter-flip circuit, there will not be enough stress for spark breakdown.
Since a very thin wire is used for it, so it converts 12.6 volts from the battery of 30,000, it is very difficult to fix it (rewind) in garage conditions. You will need to replace the coil.
Setting the gap of ignition coil.
In most modern models of chainsaws and trimmers, it is not required to set the angle of the ignition. It is set specially defined places for the protrudes on the flywheel and the shank of the crankshaft under the trench connection of these two parts. The following malfunctions often arise at the junction of these parts:
As a result, both parts (depending on the state) in case of malfunction will need to be replaced. A slightly tightened nut that holds the flywheel on the crankshaft is often leading to such problems.
It is only necessary to properly set the gap between the flywheel and the ignition coil. Depending on the model of the tool, the size of the gap can be of different. It usually is 0.2-0.4 mm. Important: the gap is set up from the side of the magnets and the ignition module. Since the flywheel is round, the usual car probe for these purposes will not work. It would be technically competent to set a gap on a special template. But it is not always possible to purchase it. Buying such an expensive template for one.time use is unreasonable. Instead of a company template, you can use a strip from a plastic bottle of water. Cut a strip from a bottle in a place where there is no embossed embossing. You can use a plastic card (not too thick). Further, the actions for the exhibition of Zazaor are approximately the same for both chainsaws and trimmers:
- Loosen the ignition fastening bolts.
- Suppry the magnets on the flywheel to the ignition coil
- Clutching between the flywheel and the coil, tighten the fasteners.
- Remove the strip
- Scroll the flywheel 360 degrees several times, monitoring that he does not cling to the coil anywhere.
All. The gap between the coil and the flywheel is exhibited. Take the flywheel before assembly and make sure that it does not catch anywhere.
Note: Do not use paper as a template. It does not have the proper elasticity, when tightening it is necessarily deformed and the gap will be incorrect.
The repair of the ignition coil is impossible and impractical. The following is a list of ignition coils that can be bought on our website.
Check the condition and, if necessary, replace with new
It often happens that users of such cars try to “save”, pouring into the tank not a fuel with an ordinary octane number, but something incomprehensible, which has been in a plastic canister for almost a dozen years.
Often, trimmers for grass do not start after they try to “put them into operation” after a long storage. Troubles with starting in this case are often justified by the incorrect actions of the user.
If you are faced specifically with this phenomenon, then when you cool, you need to close the damper, then pump up a small amount of fuel consistency in the carburetor. After disassembling and assembling the Husqvarna 142 saw, a spark was missing on the spark plug. What to do. Then stretch the launch hand to a sense of resistance, then make a trimmer for the grass with sharp and energetic movements.
How to prevent sudden breakdowns during the operation of a trimmer for grass?
So that the unit is always in a functional state, it is worth observing several simple rules:
- Carry out timely, regular technical inspection of the main mechanical nodes of the device.
- Refill a trimmer for grass with exceptionally fresh fuel, the quality and origin of which is not in doubt.
- Check after each use of the tool, whether oxides and soot on the surface of the ignition system were formed.
- Avoid the strong load of the trimmer for grass during work.
In order for the unit to remain in a working state, it is necessary to properly prepare it for storage in the winter period. First of all, you should completely disassemble the tool, and then perform washing and cleaning the constituent elements. It is also important to examine the functional blocks for damage, with the need to eliminate the deformation of the parts, all kinds of distortions, gusts of materials.
Placing a trimmer for storage grass, it is worth filling the gearbox with a sufficient amount of oil. Then you need to clean the air filter, partially disassemble, blow and rinse the unit engine. Having dried all the mechanisms, lubricate moving elements. Why does the lawn mower stall after starting? No spark in the candle. The current reaches the candle. To carry out the processing of the piston system with oils, it is necessary to first extract the spark plug. Then you need to move the piston to the extreme position, then pour a small amount of oil into the candle hole and make scrolling the crankshaft. If the gasoline trimmer for grass in the offseason is not planned to be stored in the house, it is recommended to tightly wrap the engine of the unit with an oiled rag. This will avoid the development of corrosion on the surface of important components of the mechanism.
Adjustment of the lawn mower carburetor can be adjusted with your own hands, like the entire benzo tool for the garden, is not difficult to maintain equipment. Repair, set up on your own and it is necessary.

Modern electronics revolutionized the world in many things. Even tools such as chain saws were affected by high technologies. Today’s saws are light and powerful. Electronic ignition systems are one of the most significant factors in this evolution. Below are interesting materials about such an important component of the chainsaw as the ignition coil.
Gasopil ignition systems
Not too many years ago, the ignition systems used in professional saws were cam. They were heavy, complex, expensive and prone to all kinds of problems. Especially on rainy days. Even when the saw “had a spark,” it was often difficult to start. Some saws barely produced enough energy to give an outbreak at the speed of rotation of the crankshaft. And the constant pulling of the starter’s handle was the norm.
Today’s systems are small, light, and durable. Compared to early ignition systems, they are almost reliable. The modern coil is professional and almost always serves the entire service life of the chainsaw. While changes in ignition systems were capital, sometimes problems in work may occur. Often these problems are easy to fix for yourself and do not require a trip to the workshop for expensive repairs.
What to pay attention to when it is difficult to launch the engine?
When the ignition problems arose, one of the first points for the inspection is. spark plug. Pay attention to damage to the ceramic insulator or signs of wear on the electrode. If the candle has a removable cap, make sure it will fit tight.
Next, look at the wires leading from the coil, whether there are a cliff or damage to insulation on them. The vibration of the engine can lead wires to friction against each other or another component. During friction suffers, even the strongest isolation.
Other problems arise when the wires pass between the parts of the anti.vibration system of the saw. Constant bends and stretching can ultimately lead to their destruction. Sometimes these cliffs are not obvious because they occur inside the isolation. The cliff is sometimes difficult to find, because the wire may look perfect outwardly.
The spark plug wire, also should be checked. Sometimes the cap of the spark plug can cause problems. A visible sign of the problem is a brown or burnt residue on the external ceramics of the spark plug. This is a sign that the spark walks along the external ceramic winding of the spark plug. At this time, the saw can work, but the work will be unstable and the currents will walk.
In the ignition system, the saws often fail to turn off the shutdown, they can be checked. Disconnect the wires of the switch from the module and check the ignition. Sometimes the switch makes him be constantly “turned off.”If you have a spark after the switch is turned off, replace it and test the saw.
Constantly check the wires, they should not be overwhelmed and not twisted, and the wires should not touch the vibrating parts tightly.
Features of diagnosis
Trammers for grass can be attributed from a technical point of view to complex devices. Based on this, before their operation, it is strongly recommended to carefully study the relevant instruction. However, in practice, many ignore it, often then find themselves in situations where the gasoline trimmer for the grass does not start or is poorly gaining momentum in the process. It is worth noting that you can encounter such problems by purchasing new samples of technology.
One of the most common causes of such symptoms is a long seasonal break in the operation of equipment. In addition, poor.quality and untimely maintenance can lead to extremely negative consequences. It is important to remember that this is relevant for both the Chinese lawn mower and the representatives of the model rows of eminent brands.
The key to effective and operational repair will, of course, be competent diagnostics of the device. In the process of identifying malfunctions, you will have to inspect and test, first of all, key elements. The list of such includes candles, tank, filter nodes and valves of the fuel system. As practice shows, very often the malfunctions of these elements become the reason that the lawn mower does not start. The quality and correctness of the preparation of the fuel mixture deserves special attention, especially when it comes to two.stroke engines. In relation to this parameter, the manufacturer’s recommendations should be clearly followed in order to avoid serious breakdowns and expensive repair work. In the case of, for example, with the Piston Group of ICE, expenses are able to amount to 70 percent of the cost of new equipment.
Often, the owners of the trimmers have to deal with situations when the indicated mixture is high.quality, the carburetor is serviceable and configured, and the device still does not show signs of life when trying to start the engine. In such cases, the condition of the candle should be checked. The following steps will allow to eliminate the problem:
- turn out the candle;
- wipe and dry the part (pumping is undesirable);
- remove fuel and dry the candle channel for 30–40 minutes; Such actions will avoid filling the candle with another attempt to launch;
- completely eliminate the traces of soot using a file or sandpaper;
- set the appropriate gap;
- put the candle in place.
If the candle turned out to be the working and the planting nest is completely dry, and the engine of the braid for the grass is not started, then the thread should be moistened with gasoline. It is worth remembering that regardless of the quality of the issued spark, initially in a completely dry chamber, there will simply be nothing to ignite. Faced with the fact that the spark does not act, it is worth paying attention to checking the contact between high.voltage wiring and candles. If this connection is of high quality, then it will be necessary to check the performance of the ignition control unit unit. In such cases, a qualified specialist is unlikely to do without services.
The next stage in the diagnosis of gasoline braid for grass will be checking the state of filters. Often, the lawn mower is poorly started or does not start at all on the cold due to the fact that the air filter is clogged. This malfunction can be identified by excluding it from the system. If after that the braid for the grass starts, then you will have to clean or change this element. Experienced users strongly recommend periodically blowing an air filter to maximize its operation.
The described tool can also not be started due to problems with the supply of gasoline provoked by fuel filter pollution. For the quick and efficient elimination of such a breakdown, you just need to replace the filter element with a new. It is important to remember that the suction pipe must be equipped with a filter, which is provided for by all instructions. Non.compliance with these rules and recommendations may entail expensive piston repair. In the process of diagnosing and searching for source of problems with the launch of a mower, attention should be paid to the saapun responsible for stabilizing the leveling of pressure in the fuel tank. In addition, it is necessary to check the cleanliness of the exhaust channel and muffler grid. As a rule, such problems are most often encountered during the defect of old models.
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.
Common breakdowns and how to eliminate them with your own hands
If the lawn mower does not want to start, then, first of all, check if there is gasoline in it. If it is not, share to the required level. The fact is that if the device is inactive for a long time, gasoline is “exhausted” from it, therefore, it must be drained and replaced with a new. Do this carefully so that the fuel does not get to the engine (otherwise it may be ignited).
note! If you do not know which gasoline should be used specifically for your lawn mowing model, find the appropriate information in the technical passport.
By the way, if you only plan to buy a gasoline lawn mower or any other garden equipment, we recommend visiting the Gardenmoto site.ru. There you will find the widest range of pore products by quite acceptable prices. But back to the unwillingness of the device to start.
So, the next reason why such a problem can arise lies in the incorrect position of the air damper when working the first launch. Based on the air temperature, this is either completely closed or rises in the middle position (if the temperature is 30 degrees). After that, it should be opened entirely.
We also recommend that you inspect the air filter to find out if it is dirty. To do this, turn on the lawn mower and disconnect the cable from the spark plug. Remove the lid, remove the filter, wash it with gasoline and dry it well (or, as an option, put a new one).
note! Air filter replacement should be made on average every 25 hours of using the device. Remember this!
Finally, the last reason. This is a faulty candle (it, by the way, can be just flooded with gasoline). To find out, unscrew it, clean and check for a spark. Next, close the air damper and try to start the motor. If this did not give any result, it is better to trust an experienced professional.
Recommendations for storage of gasoline trimmer for grass in the offseason
Placing a trimmer for storage grass, it is worth filling the gearbox with a sufficient amount of oil. Then you need to clean the air filter, partially disassemble, blow and rinse the unit engine. Having dried all the mechanisms, lubricate moving elements. To carry out the processing of the piston system with oils, it is necessary to first extract the spark plug. Then you need to move the piston to the extreme position, then pour a small amount of oil into the candle hole and make scrolling the crankshaft. If the gasoline trimmer for grass in the offseason is not planned to be stored in the house, it is recommended to tightly wrap the engine of the unit with an oiled rag. This will avoid the development of corrosion on the surface of important components of the mechanism.
If your lawn mower starts up, but does it not as easy as we would like, we suggest using the following tips:
- Put the tool on the side so that the air filter is at the top. What will it give? The fuel mixture will fall exactly into the bottom of the carburetor. You can still remove the air filter and pour a couple of drops of the mixture into the carburetor and then install all the parts in place. The tool will start on the first attempt!
- Perhaps the problem is in the candle, and then, unfortunately, the previous method will not help. But there is another! Twist the candle, check it for performance and dry the combustion chamber. If the part does not show signs of life, replace it with a new.
- A universal advice that will help to start a lawn mower and a saw with a snowman. But it acts if the spark plug is working, the fuel mixture is fresh, air and fuel filters are clean. So, we close the carburetor damper and perform one movement by the starter. Next, open the damper and again twist the starter 2-3 times. We repeat the procedure, after 3-5 cycles the engine will begin to start.
How to clean and store a tool?
During the operation of the lawn mower, monitor the state of the engine cooling system. The channels available in the starter housing, as well as the cylinder ribs, should always be clean. If you ignore this requirement and continue to operate the motorcycle, then you can disable the engine due to overheating.
Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair
Before cleaning, let the engine cool down. Take a brush with a soft pile and clean the outer surface from dirt. Cleaning plastic parts is carried out by solvents, including kerosene, or special detergents.
After the summer season, the lawn mower should be prepared for long.term storage. To do this, the fuel mixture is drained from the tank. Then the engine is launched in order to develop fuel residues in a carburetor. The entire tool is well cleaned of pollution and sent to “hibernation”.
As you can see, it is possible to repair the malfunctions of the household lawn mowed on their own. Service services should be contacted in case of serious breakdowns. In this case, the cost of repairs with the price of a new lawn mower should be correlated. Perhaps it will be more advisable to buy a new tool.
