The causes of breakdowns of gasoline and electric trimmers

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

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

Damage of gasoline trimmers

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

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

Malfunctions of electric trimmers

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

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

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

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

Why is the gasoline trimmer not starting for the grass

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

Fuel tank (fuel quality)

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

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

Candle and candle channel

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

Новая бензиновая газонокосилка RedVerg RD-GL40S

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

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

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

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

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

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

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

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

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

Air filter

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

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

Fuel filter

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

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

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

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

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:

  • Fuel tank (fuel quality);
  • Candle and candle channel;
  • Air filter;
  • Fuel filter;
  • Breather;
  • Graduation channel.

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.

If the trimmer engine for grass still does not start, such a cause as the lack of spark due to weak contact between candles and a high-voltage wire should be excluded.

If the connection is of high quality, and there are no sparks, most likely, you have “flew” the ignition unit. Here you can’t do without a master, t. to. The part is not repaired, but sold by a whole knot.

Diagnosis of the filters of the lawn mower

Another reason why the gasoline braid for grass stalls is an air filter. To exclude it, try to remove the filter and start a trimmer for grass without it.

If it turns out, then you will have to change the air filter to a new one, or at least blow and carefully clean the old.

You can’t start a gasoline trimmer for grass due to contamination of the fuel filter. This is the next stage of our algorithm. Here we check the state of the filter element and, if necessary, change it with the new.

When replacing, try not to leave a suction pipe without a filter, this is prohibited by any operating instructions. Rush can turn into the repair of the piston group of the engine.

Sapun and graduation channel

Often, “delicate” branded models of benzos are not launched and stall due. The main function of this element is to align the pressure in the gas tank.

When clogging this node, a vacuum is created in the tank that prevents the supply of fuel. Eliminate the malfunction can be cleaned by cleaning the sounds. You can use a regular needle for cleaning.

The normal operation of the cos with internal combustion engines can be disturbed due to the entry of dirt into the exhaust channel or clogging of the muffler grid.

There is such a problem on the models of the older generation. You can solve the issue with traditional cleaning and removal.

Complex reasons for the refusal of the lawn mower

If the step-by-step algorithm for searching for a malfunction has not given a result, and your braid for grass still does not start or stalls, it is worth examining the carburetor and the engine itself.

A clogged carburetor can become one of the reasons, unstable operation of the tool.

Three main problems can be distinguished here:

  • Clogging of channels or nozzles. All this is cleaned with special flushing or blown by a powerful stream of compressed air from the compressor. Do not use needles and wire, so the passing sections can be damaged;
  • Wear of the carburetor laying. Output. replacing the failed laying;
  • Violation of tightness. To check this indicator, you can use the usual household tonometer, replacing the pressure gauge on it with the right. Follow the testimony: if they do not change, everything is fine, and since the pressure will begin to fall, then some part of the carburetor is faulty. Will have to find it and replace it with a new.

If everything is in order with the carburetor, then the gasoline trimmer for the grass may not be launched due to wear of the piston group. If chips, scratches or bully are found, on the piston or cylinder they should be replaced.

Piston rings are subject to mandatory verification. A small rally piston when swaying the connecting rod indicates that the time has come to change the rings. This procedure is best entrusted to the specialists of the service center.

Restoring the performance of electrical equipment

Mowers, inside of which electric motors are located, most often begin to be capricious due to oxidation of contacts. The terminals are covered with a layer of scale from excess humidity in the room or in another place of storage. It is also worth checking the absence of a break in wires in problem areas. For this operation, a multimeter or other tester type is used.

When a set of garden equipment contains a brush engine, we identify the performance. Brushes can wear out quickly, leading to a lack of contact. The reptity of them costs relatively little, and it is easy to find it in specialized stores, where they sell spare parts for such a technique.

Asynchronous engines are also in wait for the malfunctions. They refuse phase.drive capacitors. A similar situation is diagnosed at home is problematic. It can be detected by indirect symptoms:

  • The sound of a buzz is heard;
  • When starting, the case twitches slightly;
  • significant heating of the motor occurs even at a slight load;
  • Reduces are reduced.

It is worth diagnosing the condition on the tolerance/button and the voltage supply to the electric motor. Когда проведено тестирование описанных узлов, а нарушений в работоспособности не обнаружено, то вряд ли удастся исправить поломку газонокосилки своими руками. Then you will have to use the services of the corporate service.

Why the lawn mower is not started, the reasons

Figure out what has brought the device into a faulty state by disassembled it. You need to do this carefully and carefully, inside there are many small details that are easy to break. There are 2 types of damage: mechanical, electrical. Consider the most popular reasons why the lawn mower does not start and stalls:

  • Carburetor failed;
  • bolt compounds were shaken;
  • Motor breakdown;
  • jam the moving components of the mechanism (crankshaft, piston);
  • Blocking a cutting tool (cylinder) by an alien object. branches, sticks, hard grass, stones, etc.;
  • The oil supply and fuel supply system is disturbed;
  • The light of the ignition failed;
  • stretched out, the belt broke;
  • a small or too large gap between the details inside the structure;
  • faulty device switch;
  • Dirty fuel hose, ventilation grilles;
  • Cunnered air filter.

With prolonged use of a gasoline lawn mower without a break, the device stalls. Why the lawn mower stalls and does not start hot? The engine is overstrain. It is better to lay off the mowing, let the lawn mower be standing, after it has stalled, most likely the reason lies in the overheating of the device.

In some cases, this is a temporary phenomenon after the motor has cooled down, the equipment can work again. But still, you should not go out for hours. With active use, the life of the equipment is reduced. On average, repair is required 4 years after the purchase of goods.

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:

Обзор RedVerg RD-IC10N: инверторное зарядное устройство гелевых и свинцово-кислотных аккумуляторов

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

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

Recommendations for operation

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

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

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

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

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

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

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

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

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

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.

All the whole, clean, works?

We try to adjust. We take a long screwdriver, we find a bolt of idle speed adjustments (it is on the throttle), twist it a couple of revolutions so that the damper is opened. We start. It works smoothly? Then we go further. Does not start or stall? Open the damper until it starts stably.

Next, adjust the quality of the mixture with a screw l. You need to achieve maximum storage speeds. Here the principle is the opposite. the more the bolt is unscrewed, the richer the mixture. After that, the quality of the mixture at maximum revolutions by the screw h.

If the adjustment of the carburetor has not given its fruits, then it needs to be disassembled. Watch the membrane, clean nozzles and inner moves. For this, it is necessary not only to have a reptile, but also preferably a reserve carburetor.

Search for breakdowns

If the trimmer for the grass has ceased to be launched, then you should not immediately sound the alarm and contact the service center, since the cause of the inoperability can be easy. Any repair of gasoline trimmers begins with a check of the presence of a spark, without which ignition of fuel in the combustion chamber is impossible. If there is no spark, then the problem is either in the spark plug or in the ignition itself. Exclusion in cases where the candle is filled with a fuel mixture with overflow of fuel above the prescribed level. In this case, you just need to wipe it dry and the coveted spark will appear.

Will also tell you about the absence of fuel flow. If it is dry and light brown, in this case, the repair of a gasoline trimmer for the grass with your own hands will be to debug the fuel pump or all these reasons are easily eliminated, the main thing is that the engine itself works properly. But if the cause of the inoperability is still hidden in the engine itself, it is recommended to contact the service center due to the difficulty of repairing. But for people who know how to hold and a screwdriver in their hands, there is nothing impossible. In most cases, a trimmer for grass ends successfully.

Not starting on a cold trimmer for grass. we eliminate the cause

On the cold.The reason is an air leak that does not allow fuel to download. In the camera.

After several jerks, he will start and stall, which is a normal phenomenon. What to do when the fuel was definitely normal, there is a spark, but a trimmer for grass does not start a gasoline? Putting the damper to the working position, start the tool again and start working.

Common causes of breakdowns

First of all, it is worth making sure of 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.

redverg, start, procedure, different, cases

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

Other tool malfunctions

If all the problems described above are checked and eliminated, and the trimmer for the grass still does not start, probably problems with the engine itself. It may reduce compression due to the destruction of crankshaft oil seals or damage to the piston group.

This more often happens with trimmers that are used very actively or for a long time: for example, in utilities. To diagnose, use a compressometer.

The oil seal protruding from the crankcase is subject to replacement. it has already hardened, has lost its elasticity and cannot fully fulfill its function

In most cases, such a repair should be entrusted to the workshop, if only because in almost all trimmers for access to the oil seals and the cylinder, you need to unscrew the nuts with a thread fixer. You can do this either with an electroger.controlle, or warming them well.

The seals are located on both sides of the crankshaft: under the starter and on the drive, and it is better to change them with a couple. Having reached the place of installation, evaluate the condition of the eye: they should sit tight, without a backlash and not to bulge, not to be crackled. Oil Sunses around also indicate the need to replace the seals.

When reverse assembly, be sure to use thread fixers wherever they were. this is a security issue.

To easily pull out the seal, screw into it 2 self.tapping screws from the opposite sides. Pull the screws in turn with the help of pliers.

Restoration of the piston group requires a specialized tool. If you are not a car mechanic for a hundred, trust the restoration of a trimmer motor for the grass to a specialist.

When opening the cylinder, all surfaces are checked for chips, bullying, scratches. To determine if the piston rings are worn out, shake the connecting rod. The slightest backlash of the piston indicates the need to replace the rings.

reasons why the gasoline trimmer for grass does not stall and does not start

If the lawn mower stalls, the reason can be any. We highlight several of the most likely reasons that the trimmer for grass is poorly started.

Poorly.quality gas mixture

It is necessary to use freshly prepared fuel. Over time, it exhales and loses its properties. Before operation, the motokos drain the remaining gasoline and season the tool with a new mixture.

There is no fuel supply

If the lawn mower is not started, the design of the fuel system may be disturbed. Bends on the pipes, their damage, the condition of the filter. all this must be checked first. It is worth testing the compounds for tightness. Leaks lead to equipment refusal.

What to do if a lawn mower or a trimmer for grass does not start

If a trimmer for grass or a lawn mower is not started, then any desire to mow grass disappears. Very often, the owners of these tools are faced with the difficulties of starting a two.stroke or four.stroke engine. for example, after winter, when the tool was not operated for a long time. It happens, and this: yesterday a braid for the grass worked, but today there is no. What to do? National Encyclopedia of Construction Profidom.com.UA recommends not in such cases not to rush to hand over the tool for repairs.

Journalists Profidom.com.UA is advised: start searching for a malfunction for our recommendations and with a high degree of probability you will manage to start a benzotrimer engine.

Where to start searching for a malfunction when the lawn mower does not start, which nodes need to be checked?

Hand starters are used to launch gasoline trimmers. Through such starters, manual movement of the crankshaft is carried out. At the same time, it is important to turn on the ignition so that when the crankshaft rotates, the fuel mixture entering the cylinder could be ignited. Inflammation of the first portion of the mixture will entail the launch of the engine, and at the same time, the trimmer for the grass is ready to operate.

However, it often happens that attempts to start the engine come to naught. Naturally, when after 5 attempts to start the engine, it is not possible to achieve success, it means that you need to start diagnostic measures. There is a special sequence that should be followed to find the reason why the lawn mower is not started, and successfully eliminate it.

Step.by.step diagnosis and checking the chainsaw

  • Check the presence of fuel in the tank, as well as the quality of a mixture of gasoline with butter
  • Determine the color of the spark plug, as well as signs of its functioning
  • Make sure an air filter
  • Check the fuel filter that is responsible for cleaning gasoline with oil entering the carburetor
  • The serviceability of the sapun
  • The reason that the lawn mower is not started, there may be a exhaust channel or muffler

Namely, these nodes are the main sources of the problem of difficult trimmer to start the grass. A more difficult problem is associated with a malfunction of the carburetor, which needs to be adjusted. Consider each node separately to find out the reasons why the trimmer for the grass does not start, and eliminate them with your own hands.

Checking the availability and quality of fuel

Do not understand why the lawn mower is not starting, then, immediately make sure that there is a fuel in the tank. Often, newcomers forget that it is necessary to periodically make pauses to season the tool with a gasoline mixture. If the gas mushroom tank is empty, then of course it will not start, no matter how much you try to do it.

If there is a fuel in the tank, but at the same time, it is impossible to start the engine engine, then do not rush to disassemble the carburetor. Make sure that the trimmer engine is launched correctly, as indicated in the instructions. If the launch is carried out according to the instructions, then it is important to consider the following points:

  • Use not just high.quality gasoline with the maximum octane number, namely, the brand recommended by the manufacturer. And far from always such a brand is AI-95 gasoline. If you do not know which gasoline is used for the lawn mower, then choose AI-92
  • The oil should be special. for two.stroke engines. If the lawn mower has a four.stroke engine, then pure gasoline must be poured into it without stirring with butter. On the quality of the oil for the engine engine, the grass should not be saved, as well as on gasoline. After all, the operational resource of the motor depends on the quality of the fuel used
  • Proper preparation of the fuel mixture. Observations show that most mowers are only the first time control the process of cooking oil with gasoline for a trimmer for grass. The greater the experience of Kosar, the less close attention is paid to the process of mixing gasoline with butter for a two.stroke engine. The ratio of gasoline with oil should be the way the manufacturer recommends. Typically, this ratio is 25 to 1, that is, 1 liter of gasoline needs 40 ml of two.stroke oil (motor oil for the car and even more so you can not use it)
  • Proper storage of fuel mixture. It often happens that after the preparation of the fuel mixture, it costs for a long time for more than 2 weeks. It is impossible to store the finished mixture of gasoline with butter for a long time, since this leads to the fact that the oil is precipitated, and thereby the properties of both petroleum products are lost. Even thoroughly stirring after prolonged storage of the finished mixture is not a reason for its further use. That is why it is not recommended to prepare more than 2 liters of the mixture at a time

Make sure that all of the above points are made, and only after that you can start checking the condition of the candle. A trimmer for grass is not started for various reasons, and most of them can be identified independently. Resorting to disassembling the carburetor, if it is impossible to start the engine, is simply irrational. The next step towards finding a malfunction is a check of the state of the spark plug.

Dry and wet candle: what does this mean and how it 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 in Banzokosa 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. At the same time, the candle should give out high.quality and constant spark. If the spark is weak or it is not at all, then the spark plug should be replaced
  • Do not start a braid for grass can even 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. To set the gap, special probes are used
