The spark is disappeared on the trimmer reason.

The spark is missing on the trimmer what to do

Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.

Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

unscrew the gearbox located at the bottom of the bar;

After removing the gearbox, you will see the end of the shaft, for which you need to pull to extract the part;

after extracting the shaft, it must be abundantly lubricated with a special lubricant “Shrus-4” or ordinary-“Litol-24”;

• Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
• After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

• unscrew and remove the mowing head;
• remove the bar from the electric motor by unscrewing a couple of bolts;
• Pull out a flexible cable from the bar;
• Lubricate the cable with grease along the entire length.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

Check the filter

Another common reason why there is no starting trimmer for grass

The presence of clogging in the filter area. To confirm the assumption, it is enough to dismantle the indicated block and try to launch the device without it. If the trimmer engine starts up, you will most likely have to replace the air filter or at least carefully clean the old. If there is strong contamination on the surface of the filter element, you must use a new grid. Do not leave a suction pipe completely without a filter. Indeed, a rush in this case can lead to the need to repair the entire piston group of the engine.

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. 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.

Checking instructions

The coil is one of the most important elements of the general ignition system of absolutely every gasoline type engine. It is this node that is considered the main in ignition systems: electronic, contact and contactless. In car jargon, this device can be found even under the name as a bobin. It can also be called a kind of miniature electric transformer. This is due to the fact that it, in fact, is a low.voltage voltage converter coming from the battery and generator, to the high.voltage. on the spark plugs. Knowledge of how to check the coil will never lose its relevance. After all, this is one of the vital nodes, the partial damage of which will lead to unstable engine activity. And a complete breakdown of this mechanism is a completely disaster for the driver, because in this case the motor will not start at all. Despite the fact that this element is not located to frequent breakdowns, this nevertheless happens, and can be as follows:

• Due to severe heating, high voltage or vibration, insulation damage occurs. As a result. a short circuit that occurs in the windings of the coil.
• Due to the faulty spark plugs, the wires of the high.voltage type are overloaded. As a result. a break in the winding.

Against the backdrop of the causes of the reel malfunction, knowledge of how to diagnose it is invaluable. Accent should be made that there are two ways to check this mechanism for performance: with the help of a spark between the light of the ignition and the machine body, as well as using the multimeter. I recommend, at the slightest signs of fuzzy engine operation, first of all check the ignition coil.Previously, for quite some time these two methods were on equal terms of popularity. But in connection with the progress and the identification of the dangerous consequences of the use of the first method (after all, this can cause “death” not only coils, but all of electronics. a trend for many modern production cars), manufacturers categorically do not recommend it. A simple and, most importantly, safe way to check this automobile node. using a special measuring device.

The first thing the car owner needs to do if he decided to independently check the condition of the ignition coil is to get a multimeter. This device does not belong to the category of especially rare or prohibited, so getting it is not a difficult task at all. This measuring device is good because it is able to work in two positions: checking voltage and resistance.

So, the instructions for checking the ignition coil using a multimeter:

• To begin with: turn off the “minus” on the battery, loosen the brackets, disconnect the coil wires, clean its body. If serious damage was discovered during this, for example, in the form of cracks or serious scratches, it is better to interrupt all diagnostics at this stage and go behind a new coil. Here it is also necessary to focus the attention of car owners on the fact that each coil has completely different indicators of the resistance of the windings, energy and duration of the spark, its current and inductance of the primary winding. In this regard, I recommend clarifying the listed technical characteristics of a particular coil.
• At the first stage of the diagnosis. checking the primary winding. It is necessary to attach the multimeter to its negative and positive contacts, having previously set the resistance measurement mode on it. It is not difficult to guess that the indicators of a car may differ from each other, and therefore it is better to immediately arm yourself with the instructions for operating your car in order to surely know these numbers. But the average resistance value that can be focused on, I will still give: from 0.4 to 2.0 Ohms. If the device demonstrates the zero value of resistance, then this is a confirmation of the assumption that a short circuit occurred in the coil. But if the multimeter shows infinity, then the reason is most likely to be a chain break.
• At the second stage of diagnosis. checking the secondary winding. To do this, the multimeter must be connected to a positive contact, as well as with the withdrawal from the wire, which is characterized by a high voltage. If we talk about coils that can boast of a plate core, then their value is 6-8 kom. And in other types, this parameter may exceed a mark of 15 kOhm.
• The resistance parameter in both cases must be carefully measured, and then compare the results with the corresponding indicators of the norm.

The coil is a fairly sensitive automobile element, and even the slightest deviations from optimal indicators can adversely affect the operation of the engine.

It should also be noted that the analyzed mechanism is in the category of those that are not subject to repair. Therefore, you can’t eliminate the malfunctions in it. you need to immediately buy a new device.

Any kind of failure in the functioning of the ignition coil is the cause of the negative impact on the overall work of the entire car. As a result. a reduction in its durability. Caring for your car is a whole art that you need to love. A certain litter in it is the diagnosis of ignition coil as a very important mechanism in the overall structure of the car. If the car owner is not confident in his knowledge and skills, then it is better to entrust this process to someone else: to call friends, acquaintances or it is better to immediately seek help from the master. But today is a time that allows you to keep abreast of absolutely everything. So on this topic you can find a lot of information not only of the text plan, but also a variety of videos on which the process of checking the coil is shown in all details. So in any case, you should not be afraid to try to do this, because the fate of the car is only in the hands of its master.

Diagnosis of malfunctions

All the reasons why the lawn mower is not started can be systematized by the specifics of the operation of individual units. The service center is systematized:

• Motor malfunction (piston wear, bearing malfunction, crankcase crack);
• Fuel consistency supply malfunction. clogged pores of an air filter or a malfunction of a carburetor;
• the ignition system does not work;
• A malfunction of a mechanical disposition. a leak of hoses, broken wires under a braid, rupture of the tubes.

The user first needs to check if there is a fuel in the tank. Starting in agreement with annotation, putting the saw on the side. Gasoline trimmer for grass; starts without problems. May not start. Set the air damper to the position “Closed”, pump up fuel, turn on the ignition and produce 3-4 sharp jerks by the starter. If the engine has earned, open the air damper. The lawn mower is not started. we repeat the operations with a slightly open air damper.

The lawn mower cannot work for a long time. Gearbox and engine will overheat. Mowing less than 15 = 20 minutes, taking a five.minute break. In hot noon, the operating time is reduced by half. When mowing weeds, sedgers, the working hours are required to reduce.

If you are unsuccessful, we begin to find the reason for the refusal:

• check the quality of fuel;
• make sure the operability of the candle and the cleanliness 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 bastard;
• 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. The causes of gasoline breakdowns and why the gasoline trimmer for grass is not that the internal combustion engine does not start. DIY lawn mowing repair, if it does not start, will require patience.

Prevention of the problem

Often, the breakdown of the ignition coils are associated with the closure or cliff of windings and mechanical damage to the magneto body. This is due to strong blows, fluid and oxidation, as well as overheating. If you avoid such incidents, you can not worry about the integrity of the ignition coil.

Important! To prevent regular failure, one of the most important components of the ignition system, you need to refuel high.quality fuel. Bad fuel spoils these details.

One of the nodes of Magneto, which regularly suffer when using, are high.voltage wires through which current from the ignition module enters the candles. They have a high service life, but the damage to them is caused by users by an inaccurate circulation when replacing candles, carefully pulling the wire itself, and not for the tip. Another problem that can happen to them is moisture and oxidation or damage to isolation. If you carefully pull out the candle and avoid the penetration of the liquid into the device, these problems can be avoided.

So, the repair of the ignition coil is not very complex and can be carried out by the user independently, but subject to the above procedure for disassembling and replacing the magneto or contacts of the interrupt.

Ignition adjustment algorithm

The ignition on the trimmer is adjusted quite simply.

Remove the casing from the engine by unscrewing all the bolts holding it. For example, on the Patriot gas.cave (Patriot) PT 2540, to remove the casing, you need to unscrew the air filter housing, and remove it with a flat screwdriver from the latches. After that, the plastic case will easily remove.

• Unscrew 2 bolts using a screwdriver (it is not required to be completely twisted), holding the magneto.
• Turn the flywheel so that the magnets are upstairs.
• Further, in order to properly set the best gap with a flywheel and coil, you can use a regular visit or a calendar. If you have neither one nor the other at hand, then to configure the ignition, you can use a sheet of A4 paper by curling it 2 times (as a result, you will get 4 sheets thickness). This thickness will be enough to get the optimal gap and adjust the ignition. Insert a business card or paper between a coil and magnets.
• The magnetic field will pull the coil to the flywheel. Holding the magneto with your fingers in this position, tighten the bolts holding it.
• Give a business card. After that, the ignition on the trimmer will be adjusted.

DIY lawn mowing repair, if it does not start, will require patience.

Elimination of the reasons why the lawn mower is not started

The fuel mixture should be prepared with accurate observance of gasoline and oil proportions. In this case, you cannot use another brand of fuel. To exclude dirt, gasoline should stand in a glass or metal dish 2 days. Cannot be used for storage of fuel plastic dishes. Distribute the oil with a medical syringe without a needle. Use only a freshly prepared mixture, without leaving an unexplored fuel in a tank. If the engine is capricious, the lawn mower stalls, when you press gas, it may be guilty of fuel.

Reasons why the lawn mower is not started

Many problems with benzotrimers arise due to improperly prepared fuel mixture. In two.stroke engines, lubrication is produced by special oil (not ordinary motor!) mixed with gasoline. If the oil is not mixed with gasoline, then the lawn mower will quickly fail. Oil/gasoline is mixed in the proportion indicated in the instructions of the trimmer for grass. This is usually 1:40 or 1:50.

Sometimes the question arises how much oil and gasoline contains a proportion of 1:50.

The numbers mean the following: fifty parts of gasoline are taken per part of the oil. Hence: 1000 ml (1 liter of gasoline) we divide by 50, we get 20 ml, that is, 1:50.

Thus, you can calculate the composition of the fuel mixture (gasoline/oil) in any proportions. To add oil to gasoline, not “on the eye”, you can take a medical syringe for 20 ml, dial oil into it and “inject” into the container for the preparation of the fuel mixture.

For the period of engine running (this is approximately the work of a trimmer for grass by 2-3 tanks) the amount of oil can be increased. Mix it with gasoline in a ratio of 30: 1.

Insufficient amount of oil mixed with gasoline leads to increased wear of the cylinder.piston group. An excess of oil in the mixture, although not so fatal, is also harmful. Cooking piston rings, rapid formation of soot in the combustion chamber, and a drop in engine power may occur. The mesh screen of the muffler is closed. Therefore, some users of our site (after the end of the warranty period for a trimmer for grass) recommend solemnly melt for the last time and dismantle it.

Gasoline used in motorcycles. AI 92. The brand of gasoline is accurately prescribed in the operating instructions. Do not try to “force” the engine, filling the 95th gasoline into it. This can lead to overheating, unstable and poor work of a trimmer for the grass, its failure.

It is not recommended to leave fuel in a trimmer tank for grass with a long break in operation. It is better to finish the working day by completely developing the entire mixture. If this is not done, then because gasoline from the engine will evaporate during the night, and the thin oil filter will remain, carburetor jacks may clog. This will cause difficulties in starting the engine the next day.

It is also necessary to observe safety precautions when storing fuel. Many pour gasoline into a plastic bottle of water. We will figure out whether to do so.

-In no case should you store gasoline in a plastic container from under the water. When mixing the fuel mixture, a static charge accumulates, you can “catch” the spark.

Therefore, at gas stations it is not allowed to refuel gasoline into plastic canists, only in metal. Before pouring gasoline in a metal canister, it is better to put it on the ground, so the statics from the case are removed and it will definitely not be “sparking”.

But there are situations when simple manipulations with a motorcycle do not help. The engine still does not start. In this case, “heavy artillery” is in progress. we are diagnosing the power and ignition system, guided by the rule “the motor does not work if there is nothing to burn or set fire to nothing”.

Electrical equipment is checked as follows:

• Twist a candle, Osmatrey gap between the electrodes. You can set the right gap between the electrodes in the “grandfather” way. Then we take the blade from the razor, break it 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 there is a spark, it beats well at one point, then, even though the trimmer for the grass does not start, but the gap is adjusted as it should. If not, the spark is weak or “wanders”, then it is necessary to adjust the gap between the electrodes again.

Also, the ignition coil can be broken in electrical equipment. That is why the gasoline trimmer for the grass does not start or start and works with interruptions, and then immediately 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.

Vacuum carburetors are put on trimmers for grass. When disassembling it, cleaning or washing, you need to be extremely careful. in no case do not disassemble the lower part of the carburetor where the primer is located. Air filter (it is visible if you remove the protective casing from the carburetor) should be washed with detergents. Best. for washing dishes. After drying, put it back. Rinse the carburetor with clean gasoline and blow out all the holes by the pump. We also wash the filter of the gas pipeline, then we dry everything and collect everything. Usually, after all manipulations, a gasoline trimmer for grass, which worked poorly and just tried to stall, begins to start like a new.

Thin cable instead of fishing line, whether it is worth placing it on a motorcycle

This thought comes to mind almost everyone who had to pump out 10 acres overgrown with high grass. The idea does not seem so bad. The cable is stronger than the fishing line, not so wear out. However, not all so simple.

Replacing Magneto

To correctly purchase Magneto for replacement, you need to contact a specialized store or service center and name the brand and model of a trimmer for grass.

Advice! Another good decision will be the provision of an old ignition coil, according to which the seller will be able to choose a new part.

To remove the magneto, you need to remove the plastic casing from the trimmer for the grass. On different models of motorcycle, this process is different. It is usually necessary to unscrew the bolts, but on some benzotrimers it may be necessary to squeeze the latches. After that, access to the coil opens. To remove the part, you need to unscrew the holding fasteners and disconnect the wires.

When installing a new part, you need to correctly set the distance between the flywheel and magneto. To do this, you need to turn the flywheel with magnets up, install the coil and fix it, but the screws do not completely tighten, so that there is a short distance between the details. Further, between the coil and the flywheel, it is necessary to put a calendar, a business card or four.folded paper sheet of A4 format, you can also use a plastic strip cut out of the bottle. Such tricks will provide a suitable gap between the flywheel and magneto. A more competent solution will be the use of a special template, but it is impractical to purchase it for the sake of once. Next, you need to tighten the fasteners, remove the object between the details, and, holding the magneto with your hands so that it does not spin, tightly tighten the fixing screws. After that, you should crank the flywheel and make sure that it does not catch the coil anywhere. Now you need to connect the wires and insert the candle into the cap, and then check the operation of the device.

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.

The second is a carburetor

It is not necessary to disassemble the node right away, especially if the engine stalls after starting or does not hold idle. First try to change fuel, maybe an excess of oil. You can inject the cleaner air filter, let the motor “laugh” a little at maximum speeds.

Next, go in order. the air filter, the fuel filter (it can be outside and in the tank), the fuel pump button, the integrity of the hoses. Gas tank plug. the ventilation valve can be clogged, the motor simply does not pump gasoline. Get everything. and will work!

Be sure to look at the connection of the carburetor with the intake manifold! Elsey there sucks air and there is no tightness. eliminate!

The dosing needle hangs. the problem is also in some models. It is enough to push it down, or remove and polish it with a velvet.

You can pull the hose from the carburetor, see if the fuel is coming to it when pumping. It is clear that you often need to remove plastic casing for verification, break your fingers on the latch, but still sooner or later you will have to climb there.

Lack of spark. checking the ignition module

Possible signs of failure of the ignition module:

If the wires and candles are in order, it is necessary to test the ignition module. We combine one probe of the multimeter with the module connector, and connect the second to the “mass”. After that, we try to start the engine. If the display of the device is displayed about 12V, the module is working.

Low voltage diagnosis

For this method, you need to find a 2-3 watt control lamp with a voltage of 12V. We connect one contact of the lamp to the contact of the low voltage of the trambler, and the second to the mass.

The next step is to close the Trumbler’s contacts and turn on the ignition. If there is no problem in the low voltage circuit, the lamp will go out with closed contacts and burn with open. If the opening of the contacts does not lead to the glow of the lamp, the cause of the breakdown is the primary winding of the coil or low voltage wires.

If the lamp shines continuously, regardless of the position of contacts, this indicates such possible breakdowns:
