The gasoline trimmer has overheated for the grass and does not start. In no case should not be stored…

The trimmer for the grass does not start hot

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.

The main malfunctions of gasoline and electric trimmers

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.

gasoline, trimmer, grass, does, start

Candle and candle channel

So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is worth checking the candle channel: whether it throws it with a combustible mixture.

Often users transfer the air damper to the “OFF” position when starting, and when the engine started, they do not transfer it to the “ON” position, after which it stalls.

Further, an attempt to start the internal combustion engine to again leads to the fact that it floods the candle with gasoline, and the start becomes impossible. To diagnose and eliminate the possible problem in this node, do the following.

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

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

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

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

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

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

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

To exclude the malfunction, it will be necessary to use a tester to check the Magneto trimmer for the grass, namely, its primary and secondary winding. On the primary winding, the resistance should be in the range from 0.4 to 2.0 Ohms.

If the device shows 0. this means that there is a short circuit in the winding, and if infinity is a clear sign of a chain break. The resistance on the secondary winding should be in the range from 6 to 8 kOhm.

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

Air filter

If your lawn mower does not start well or stalls immediately after starting, you should pay attention to the air filter, since it can be clogged, as a result of which the air does not enter the combustion chamber, and fuel ignition does not occur.

gasoline, trimmer, grass, does, start

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.

What could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

  • the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
  • the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
  • mechanical damage to wires, tubes, hoses;
  • The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.

Ways to eliminate breakdowns

Subsequent work is likely on the carburetor:

  • cleaning and adjustment of the fuel supply valve;
  • similar work with a valve producing redesigned gases and pairs (after burning fuel);
  • replacement of the spring more weak on the entrance valve;
  • restoration of the tension of the carburetor cable;
  • replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
  • changing the rotor damper disk;.
  • Change of faulty wire or ignition coil.

Immediately after the start

Smelting Motokos or a trimmer for the grass after starting is justified by subsequent reasons:

  • impressive of previously adjusted valves;
  • first the wrong settings of the valve mechanism;
  • clogging with deposits of the fuel supply valve;
  • the hose is worn or poorly annexed.

Due to the violated method of injection of a fuel, a lawn mower or a trimmer for grass is very vibrated in work.

Main reasons

The following reasons are possible why the lawn mower or trimmer for grass stalls when trying to re.start and continue the interrupted work:

  • malfunctions in the engine;
  • refusal to supply gasoline and oil;
  • damage to pipelines (capillaries, hoses, pipes);
  • malfunctions in the ignition system.

General description of problems with a scythe or trimmer is not enough here. Clear and immediate repair, high.quality maintenance is impossible without specifying the identified cause.

With gazeaming

You click on gas. and the trimmer for the grass stops working, does not develop momentum. The following alleged reasons are possible:

  • The tuning of the carburetor was lost, which appears with an increasing load on the drive itself. after its long downtime or when working in extreme conditions;
  • The fuel valve is clogged with deposits;
  • The carburetor cable is weakened and sag;
  • Excessively stretched, possibly torn off the fuel supply hose;
  • The check valve (sapun) clogged with deposits. fuel does not enter the tank with fuel.

Important! Problems in the carburetor itself give themselves out the vibration of the lawn mower.

With an increase in speed

If the lawn mower (or a trimmer for grass) has stalled when the engine speed is added, check the device according to the following signs:

  • clogging or sticking a valve built into the gas tank cover;
  • valve adjustment violation;
  • A failure in the work of pistons and cylinders. from vibration during the work of a braid for grass or a trimmer for grass, random blows directly in the session of the mowing of grass;
  • violation of the supply of fuel mixture;
  • excess air pumping into the motor;
  • cracking of the fuel intake hose, weakening its compounds.

When the fuel.heating mixture is served with the right portions to the engine in a timely manner. it burns the amount that has managed to enter from the moment of the last gallpling, and he stalls again.

When working idle

Having launched a trimmer for grass or a motorcycle at idle, you find that the device is starting up. but it swallows, after working, say, 5-10 minutes. The reasons here may be as follows:

  • clogging, violation of carburetor adjustment;
  • Initially incorrect configuration of the valve mechanism of the carburetor;
  • air filter clogging;
  • reducing the speed of the gearbox (if any). the incorrect ratio of the fuel mixture;
  • clogging the throttle;
  • penetration of excess air into the fuel system;
  • The fuel ends in the tank (and oil in the tank, if the engine is four.stroke).

If there are problems directly with the carburetor, the machine will stop both after a cold start and after launch on the already worked engine.

Immediately after the start

The stalling of motorcycles or a trimmer for the grass immediately after the start is due to the following reasons:

  • impressive of previously adjusted valves;
  • Initially incorrect setting of the valve mechanism;
  • clogging with fuel supply valve;
  • the hose is worn or poorly attached.

Due to the violated fuel injection algorithm, a lawn mower or a trimmer for grass is greatly vibrated in work.

In the process of warming the engine

If the engine heats up too fast, overheating. a lawn mower or a trimmer for grass works unevenly, as if jerking. After which she stalls. The reason may be as follows:

  • boiling gasoline;
  • The ignition wire was damaged (poor insulation);
  • The coil in the ignition system has noticeably burned out, inter.seal circuits appeared.

The same heating is observed when using rotary (not disk) damper.

When opening an air damper

A lawn mower or a trimmer for grass stalls when raising the damper for the following reasons:

Ways to eliminate breakdowns

The following works are possible by carburetor:

  • cleaning and adjustment of the fuel supply valve;
  • similar work with a valve producing spent gases and pairs (after fuel burning);
  • replacement of the spring weaker on the entrance valve;
  • restoration of the tension of the carburetor cable;
  • replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
  • changing the rotor damper disk;.
  • Change of faulty wire or ignition coil.

The list of work on the work may also include the cleaning of the nozzles (in a 4-stroke engine), replacement of the valve washer, gaskets in tanks and so on.

Ways to eliminate breakdowns

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

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

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

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

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

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

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

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

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

Recommendations for operation

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

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

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

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

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

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

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

It is important to remember that competent operation of motorcycles and its timely maintenance (independent or in the service) is the key to 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.

Basic rules for the operation of the lawn mower

The lawn mower needs high.quality and accurate operation. The estimated period of its service and the absence of any serious malfunctions depend on this.

  • monitor the cooling system during operation;
  • Timely clean the charter channels and the starter ribs, and special detergents or ordinary kerosene should be used for cleansing;
  • cool the tool before subsequent cleaning.

In the case of draining the fuel, you need to give a benzos to work at idle speed until it is stalled. This will make it possible to remove all the remains of the working mixture, regardless of the power of the device.

How to prevent a breakdown during storage?

Lawn mowers are used in the warm season. For the winter they are cleaned in storage in the pantry, closet or garage.

Maintenance of the trimmer for grass should be produced several times a year (in t.h. after winter storage) to increase its possible service life

To prevent a tool breakdown, you need to properly prepare it for seasonal storage:

  • Drain the fuel mixture. it must always be drained if you are not planned to use the device within a month, The fuel decays into various heavy fractions over time, which can score the channels of the carburetor;
  • completely disassemble the lawn mower;
  • Rinse, clean and dry all the details to which there is access;
  • inspect all the elements of the trimmer for the grass for damage;
  • eliminate all possible malfunctions, distortions and minor defects;
  • pour a sufficient amount of oil into a gearbox;
  • partially disassemble the engine;
  • Rinse and grease all the necessary elements in t.h. piston;
  • Clean the air filter.

If the lawn mower is stored outside the house and the residential area, it can be wrapped in an oiled fabric. This minimizes the risk of rust on the instrument and increase its life.

Thorough preparation and processing of a trimmer for grass will allow you to keep the device for several seasons without a question.

Benzotrimmer loves cleanliness. It is necessary to monitor the purity of the air filter and fuel. It is better to defend gasoline bought at a gas station for 2 days and pass through the simplest filter. a piece of bike matter.

We check the electrical equipment as follows:

We unscrew the candle, examine the gap between the electrodes. We set the right gap between the electrodes can be a “grandfather” way. We take a blade from a razor, scraps in half and insert a home.made probe between the electrodes. If the blades enter tightly, then the gap is perfect.

We put on a candle cap of a high.voltage wire and lean the candle against the metal surface of the engine. Twist several times by the starter. If the spark beats well at one point, then the gap is adjusted correctly. If not, the spark is weak or “wanders”, then it is necessary to re.adjust the gap between the electrodes.

Also, the ignition coil can be broken in electrical equipment. In this case, the lawn mower will not start or start and works with interruptions, and then stalls, or “hot” does not start at all.

You can check the serviceability of the coil in the same way as when checking the spark: we unscrew the candle, lean it against the trimmer body for the grass. If there is no spark with a jerk of the starter, or it appears through time. you need to change the coil.

Diagnosis of malfunctions

The lawn mower cannot work for a long time. Gearbox and engine will overheat. Mowing no more than 15 = 20 minutes, taking a five.minute break. At a sultry afternoon, the operating time is halved. When mowing weeds, sedges of work, it is required to reduce the time.

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

  • Check the quality of the fuel,
  • verify the operability of the candle and the purity of the candle canal,
  • check the cleanliness of the air filter,
  • make sure that the fuel filter is not clogged,
  • Check the cleanliness of the saapun,
  • Clean the exhaust channel.

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

How the saapun affects the possibility of launching the gas mowing engine

Having excluded the malfunctions of the filters of the lawn mower, it is necessary to check the saapon. The cabin is called a detail that is responsible for the normalization of pressure in the tank. When the fuel gradually leaves the tank to the carburetor, then the pressure increases (the vacuum is created). To discharge the vacuum inside the tank, a saapun is used. a kind of valve that is on the tank cover of the tool. This valve has a filtering element through which the air entering the tank is filtered.

Over time, the filter clogs, and becomes the reason for creating a vacuum in a gas tank. Trite, but in 30% of cases, a trimmer malfunction for grass in the form of the impossibility of starting it is associated with clogging the cabin. The trimmer’s saapun can be cleaned, and the operation of the tool can continue. Make sure that the cause of the trimmer‘s malfunction for grass is precisely the sapun can be as follows:

  • Wrap the gas tank cover
  • If air is pulled when diluting, then it is already possible to assume with 100% confidence that a saepun has come out of order
  • Twist the lid and start the engine of the lawn mower. If the trimmer for the grass starts, but after a while (when the amount of fuel in the tank is reduced) stalls, then it is necessary to clean the saepun

You can clean the bacon through a conventional sewing needle. Many do not even know about this important detail, so they often do not understand what to do when the mowing benzotrimer engine does not start. Answering the question of the influence of the saapun on launching the motor, I must say that it has a direct effect. Excessive pressure in the tank prevents the fuel supply to the carburetor, so the engine does not start.

How to prevent sudden breakdowns during the operation of a trimmer for grass?

In order for the unit to be always in working condition, it is worth observing several ordinary rules:

  • In time, conduct a constant technical inspection of the main mechanical components of the device.
  • Refuel a trimmer for grass with only the latest fuel, the quality and origin of which does not cause fluctuations.
  • After each use of the tool, inspect whether oxides and soot on the surface of the ignition system have formed.
  • Fear huge loads on the trimmer for grass during operation.

So that the unit remains in working condition, you need to correctly prepare it for storage in winter. First, you should make the tool absolutely disassemble, and then wash and clean the constituent elements. It is also fundamentally to look around multifunctional blocks for damage, as needed to exclude deformation of parts, various distortions, gusts of materials.

Checking filters

Another all-produced prerequisite, due to which a trimmer for grass does not start, is the presence of a blockage in the filter area. To confirm the hypothesis, quite dismantle the designated block and experience the unit without it. If the engine of the trimmer for the grass has launched, most likely you will have to create an air filter substitution or at least perform a painstaking blowing of an old. In the presence of abundant contaminants on the surface of the filter element, you need to use the latest grid. Relying to similar actions, you should not leave an absorbing pipe completely without a filter. After all, rush in this case can lead to the need to repair the entire piston group of the unit engine.

The lawn mower is not started, the spark is gone

The loss of the spark enters the contact verification and the correctness of the clearance between them, conducting the wire to the candle and the candle itself. The sparking method. turn out the candle, connect the wire to it, attach the candle sideways to the motor’s casing and pull the lawn.mowing a couple of times a couple of times, while you need to look at the corner and contact of the candle, you should run a spark between them. If there is no sparks, take the latest candle to make the same function, if with all this the spark is not tracked down, the inconsistent in the wire or contacts is made, it is better to change them.

Maintenance and prevention of launch problems

So that the tool serves longer and does not create problems, keep it clean and regularly maintain.

Do not store the refueling lawn mower: leaving it for more than 2 weeks, and even more so for the winter, drain the remaining fuel from the tank, then start the motor and let it work until it stalls yourself. Leaving the tool for the winter in the barn, wrap the motor and knives with an oiled rag.

For lubrication of a 2.stroke motor before storage, unscrew the candle and raise the piston with the starter to the very top. Drip a little motor oil from the syringe and use the starter several times cranks.

In the spring, before the first use after downtime, it is advisable to check the candle and filters, disassemble and rinse the carburetor, even if there are no problems with the launch.

Conclusions and useful videos

For clarity, we offer a video with the analysis of common problems:

To check the carburetor or if you decide to change the oil seal yourself, it will come in handy

Dismantling and cleaning the carburetor is described in sufficient detail here:

If your lawn mower does not start, do not rush to look for a master to repair it. It is possible to independently find and eliminate the cause not only much cheaper, but also faster and easier.

Most trimmers are arranged almost identical, the structure of small details may differ and, of course, the quality of their performance. Use and store your tool carefully, do not spare money for fuels and lubricants and time for minimal service, and the trimmer for the grass will become a trouble-free assistant for many years.
