Install a gap on a trimmer like ignition coils. And again the carburetor.

trimmer for grass what gap on the coil

Consider the most common breakdowns associated with the ignition system of the chainsaw.

Feature or humidity of the candle

In the absence of ignition, there is no opportunity to start a chainsaw motor. When examining the system, we see that a black feld was formed on the candle. This indicates that a malfunction should be sought in the work of a carburetor, a piston group or reconsider the ratio of refueling oil and gasoline.

If the candle is wet, this speaks of the redundancy of fuel. Check all hoses to tightness, change those that have holes and cracks. Peel the candle from the carbon fiber, dry. Try to start the engine.

If the candle is dry, it was not thrown by technical liquid, check the presence of a spark. To do this, unscrew the candle, put on a high.voltage ignition cable on it and press to the motor body. After that, sharply start the starter. If there is no spark, change the candle and repeat everything first. A spark appeared. start the engine!

BB wire cliff

If the new candle also did not give a spark, it is necessary to test the wire. To check the integrity of the wiring, it is best to use a special tester. a multimeter, which was talked about at the beginning of the article.

The cliff of the chain in the coil, you can see checking it with a multimeter in resistance mode, the meaning will strive for infinity.

Large gap between the ignition module and the flywheel magnet

In the case of the resulting large gap in the coil, it is necessary to independently set the value by using the algorithm above the above.

The lawn mower will not start or start, but stalls. What is the reason?

To understand this, you need to know the principle of operation of the unit as a whole. It happens so, just purchased, a new saw is not started, and running around the service centers begins, in such cases it is recommended:

Carefully read the instruction manual; In detail to study the method of first factory and run.mowing; Try to understand the principle of the product; How to pump gasoline and so on.

The quality of gasoline is poor; improper proportion of gasoline and oil; clogging of the filter of thin cleaning; The spark disappeared.

The lawn mower is not started after winter

In such cases, it is necessary to conduct maintenance of the unit. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean each node, rinse. Pour the filters with air

Pay attention to the quality and octane fuel number

One more fact must be taken into account that with the long storage of diluted fuel mixture, it falls working qualities, which also leads to the consequences in which the lawn mower will not start. Therefore, it should be diluted with portions, that is, the amount of a mixture that is produced at a time. The operating instructions clearly describe and are given clarifications on the proportion of mixing gasoline and oil. Straighten compliance with the correct proportions will at least save you from several questions, why the lawn mower will not start and what to do in such cases.

The lawn mower is not started on a cold

When starting a cold motor, it is not recommended to press the gas. Having tilted the lawn mower so that the air filter is on top, click on the fuel suction button 5-6 times, install the function of switching functions to the Start position, pull the starter’s cord several times until the motor starts up. After a few seconds of the engine, turn off the start system.

The lawn mower is not started on hot

If the lawn mower was recently at work and did not have time to cool down but did not want to start. press the gas trigger, sharply pull the starter’s cord several times until the engine is started and only then the gas trigger is released. If a lot of time has passed and the lawn mower managed to cool, then it must be started as with cold. If the above methods did not help, the lawn mower did not start, then you should contact the service center.

If the owner of the lawn mower wants to establish the operation of the ignition system on his own, he should understand the principle of operation of this unit. In the internal combustion engine, it consists of a flywheel and magneto (coils). In turn, the flywheel includes a impeller that performs the function of cooling the motor and a number of permanent magnets.

Operating principle

When the flywheel rotates, an electric current is generated in Magneto, which creates a spark on the spark plug at the moment when magnets pass under the coil.

Before starting the ignition of the trimmer for the grass, you need to cut off other probable causes of breakdown and make sure that the problem is really in this node. For this, it is necessary to carry out a number of actions in the following sequence:

• inspect the ignition coil body for damage and defects;
• make sure that there are no pollution on all nodes and elements conducting current;
• check the integrity and isolation of the wiring, contacts, the strength of the fastening, the presence of rust at the joints;
• inspect the candle cap, as it regularly breaks away from the high.voltage wire, and they try to restore it manually, and any unreliable connection lowers the power of the electric arc of the candle;
• check the candle, since the quality of modern gasoline very quickly disables this part, but there is another possible problem. the candle is wet;
• make sure the circuit switch is working.

By excluding all possible malfunctions, you can proceed to adjust the ignition of the coil.

Features of adjustment on different models of trimmers

Operating principle

It is necessary to adjust the ignition system so that the fuel is ignited at the right time in the combustion chamber.

If the flywheel is shifted to the shaft relative to its original position, the fuel is ignited faster than the piston overcomes the upper dead point. As a result of this, the piston moves back, and the crankshaft rotates in the opposite direction. You can determine the early fire of the fuel by a broken launch cord, a broken starter node or other breakdowns.

Sometimes ignition is late. The piston compresses the irreparable fuel, and then goes down, and only then the spark forms. As a result, the engine either does not work or its power is reduced, and the speed is gaining much slower.

Typically, a flywheel with magnets is installed in an ideal position, as if coordinated with the operation of the piston, and in order to avoid displacement, it is carefully fixed. This allows us to say that an incorrect installation of a part is impossible. But if the shift of the flywheel is a confirmed fact, then it is a failure or accident.

Setting the ignition system is performed simply and identical to different models of trimmers, whether it be Stihl FS55, Al-KO Sun 4125 or other lawn mower. First you need to remove the casing from the engine, having previously removed the fixing fixing. This stage of disassembly may have differences on different models of motorcycle (described below). Next, you need to partially unscrew the fasteners fixing the magneto, and turn the flywheel so that the magnets are at the top.

To make the optimal gap between the coil and the magneto, you must use a special template. It is impractical to buy it for a single use, therefore, as an alternative, you can apply a business card or a small calendar, as well as a paper sheet A4, folded four.

Then the coil will be pulled to the flywheel with a magnetic field. Holding the magneto in this position, you need to tighten the fixing fastener, and then pull out the business card. After that, you need to scroll several times a flywheel to make sure that he does not touch the coil at all. The process is over. the ignition on the motorcycle is exhibited. Read more the process of adjusting the trimmer ignition system can be studied on the Internet, where many videos are available to this topic.

Why do you need a good spark.

The quality of the spark determines its ability to ignite the properly formed air-fuel mixture in working conditions. A weak spark in high pressure and temperature in the combustion chamber cannot do this. The ignition occurs later or does not occur at all. There is uneven engine in the engine, the engine does not gain momentum, there is vibration, detonation, the starter can have the effect of the “rear impact”.

The insidiousness of such a breakdown is that the diagnosis below does not give one hundred percent confidence in the effectiveness of the ignition coil. Such an implicit breakdown when there is a spark, but this is not entirely correct, often misleads and makes you write off problems with the ignition coil with a malfunction of the carburetor.

Typical actions in such cases are an increase in fuel supply. It turns out that the spark can ignite such a spark, but it does not have the right. But the use of an enriched mixture leads to the rapid wear of the cylinder.piston group and muffler. Therefore, in such controversial situations, check both the carburetor and the ignition reel.

Installation of the ignition system.

There is a impeller on the flywheel, which works like a engine cooling fan. There are also permanent magnets on one side of the flywheel, the figure is shown by the arrow.

When the flywheel rotates in the coil, an electric current is produced, which serves for a spark on the spark plug. The spark appears at the moment when the magnets are directly under the magneto.

• Loosen the ignition fastening bolts.
• Direct the magnets on the flywheel to the ignition coil
• Clamping the flywheel between the flywheel and the coil, tighten the fasteners.
• Remove the strip
• Scroll the flywheel 360 degrees several times, making sure that it does not cling to the reel anywhere.

All. The gap between the coil and the flywheel is installed.

How to choose a trimmer for the head of the head?

So that the head of the mower is highly efficient, the owner of the bushore should approach it correctly. In this case, several factors should be taken into account:

• An experience. If the buyer. Novice gardener, it is best to buy an automatic coil. Semi.automatic and manual coils are best suited for more experienced gardeners;
• Material. The reliability of the coil depends on this. They are considered the most durable metal models, but they weigh much more than standard plastic devices. When working with a metal coil, the braid engine is under a large load, so you only need to buy them to work with a powerful brush;
• The diameter of the used mowing fishing line. For medium power trimmers, coils are used, which can be tightened with a wire thickness of not more than 1.6 mm. lawn mower with a capacity of more than 2.5 liters. FROM. Lamps can be installed that can be delayed using a cutting cord with a thickness of more than 2 mm.

An important role in choosing a coil is also played by the simplicity of its design. For beginners, coils consisting of a minimum of parts are best suited. experienced gardeners can use heads with a large number of elements in their design.

TOP 3 most reliable drums for home use

The market has a rating of the most durable mowing heads. They are distinguished by the simplicity of the device, reliability and resistance to damage. These include:

3rd place. Bosch K-103. This is a universal coil weighing about 300 g. Most often used to equip Makita and Hyundai motolers. The model is characterized by low energy consumption, impact resistance and durability. The core and its other parts are made of forged steel, and the case. From plastic;

2nd place. Flymo 15. This semi.automatic model of a trimmer for grass is equipped with a thin cup, which increases the flow rate. Nevertheless, he worked perfectly when he mowed grass in rocky terrain. To work with it, you need to use only a thin fishing line for a trimmer;

1st place. EFCO 8100. This model is one of the most reliable mowing heads. It works in fully automatic mode, which facilitates its filling with a cut cord. Only thin hair is used to work coil. The model of the model is made of durable multilayer plastic.

Despite stability and durability, all these coils are much cheaper than other analogues of lower quality, which makes them leaders in the post.Soviet market.

The main malfunctions of the coil

Users of the electrimmer and lawn mower often face a problem associated with a semi.automatic braid head. Coil malfunctions can be as follows:

The fishing line for the trimmer does not extend automatically

If, with a light blow, the trimmer coil button for grass on the ground is not lengthened for a trimmer, then the reasons for this may be the following.

Option 1. there was a snack, t.e. Squeezing the cord between turns. This problem usually appears if the user wound a fishing line for a trimmer to the coil unevenly, with the intersection of the turns, or wound it with insufficient tension. In the latter case, when the mowing head is rotated at large revolutions under the influence of centrifugal force, the cord begins to drag on, as a result of which the interitral clamping of the fishing line is possible. To eliminate the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, with even turns with good tension.

Option 2. too short ends protrude from the head. A fishing line for a trimmer may not exit when hitting the ground, if its ends sticking out of the head, insufficient length (short). In this case, the centrifugal force is not enough for the fishing line for the trimmer to stretch. Therefore, it is required to stop the unit (drown out the engine or turn off the ethletric trimmer for grass from the network) and pull the fishing line for the trimmer manually, after pressing the button.

Option 3. a fishing line for a trimmer was soldered inside a mowing head. This leads to the fact that the coil is stopped and does not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil with prolonged operation of the unit, a fishing line on solid items.

• In the first case, the cord of third.party manufacturers can be made of low.quality and fusible materials that do not withstand the mechanical and temperature load. Therefore, preference should be given to “branded” fishing.
• But, if you still purchased a fishing line for a trimmer of unknown quality, and it is often soldered during operation, then you can follow the example of some users who, after refueling the cord, moisten it either with silicone grease (from the spray can) or mineral oil). This procedure greatly reduces the likelihood of soldering a fishing line among themselves.
• Also, a fishing line for a trimmer can sleep if during a mowing it hit a hard object (stone, fence, dry branch, etc.D.). As a result of this, it is slightly stretched and draws back into the head with high speed. The cord is heated from friction, and its turns are sticking together. The only thing that can be done to eliminate this malfunction is to open a trimmer coil for grass and rewind a fishing line for a trimmer.

The cord spontaneously lengthens

There are situations when a user of a trimmer for grass notices a very fast fishing line consumption. At the same time, he never hit the ground with a button to lengthen the fishing line. The reason that the fishing line for a trimmer spontaneously lengthens, cutting off a special knife on the casing of the device, may be the absence of a spring in a mowing head. Often beginner users of mowers, trying to charge a fishing line for a trimmer into a coil, forget to install a clamping spring in the head, or completely lose it when opening the lid, and in the future, they do not even suspect its existence.

Anti insecticidal lamp from insects. whether they actually work.

With the advent of a summer season, as well as on vacation in a country house, in addition to pleasant troubles and worries, the question of the fight against various insects and mosquitoes that prevent us from spending the evening time arose acutely.

Hearing their squeak in the dusk of the night, only one desire appears. to kill. Because you clearly understand that because of these creatures of a calm sleep you will not have.

To be fraught with various kinds of ointments or spray with sprays by repellents, most of us do not have much desire.

over, in the heat, along with then all this can fall into the eye. And when applying to your hands, even in food.

I always want invisible, not causing any inconvenience, but at the same time an effective means of combating these pests.

Not many people know, but such a cheap and affordable option like a grid, as a result, greatly blocks the access of fresh air into the room.

It seems to be a grid with holes, and there will be no actual movement of air from the street to the house. Only if a draft does not appear.

Let’s look at their types and all the nuances of operation in more detail. Whether they actually work or is it a useless advertising lure that makes us waste money.

There are many reviews and reviews on the Internet for these lamps, and they are all very contradictory.

What is the lamp from mosquitoes and what is its principle of operation?

Behind the beautiful lattice plastic case, which can be of any shape and is designed to protect the person himself from random touches, there are metal plates.

High voltage is supplied to these same records. Although it is high, but in terms of human security, everything is fine here.

Twist of course pulling, but not deadly. over, if mosquitoes are killed instantly, then with flies or with copies more, for example, butterflies or moths, they may not cope the first time.

Therefore, they can most often be seen sluggish at the bottom of such traps or on the floor next to them. What can we say about a person.

Keep in mind that even after pulling out of the outlet, a charge from the capacitor still remains between the plates.

To remove it, just closed the plates with the tip of a ballpoint pen or screwdriver.

Behind these plates there are LEDs that must radiate ultraviolet light with a certain wavelength of 350-360NM, thereby attracting mosquitoes.

Many “experts” scare that such ultraviolet radiation is harmful to vision and burn your eyes. So such traps lamps are harmful not only for insects, but also for humans.

But this statement is true only for powerful quartz lamps. Therefore, under their radiation and put on glasses.

In the same bulbs, ultraviolet radiation will be even less than from solar radiation in a clear fine day.

If it were a directed laser beam, to a specific point of the room, and you fell under its action, then another thing.

Although I must admit, there were attempts to introduce and full.fledged laser guns, which, with their rays, would knock down mosquitoes on the approach.

Engaged in the project and drain of their money, the well.known Bill Gates and his wife Melinda.

The ultimate noble goal was to help African countries in the fight against malaria.

But in the end, the project was expectedly turned as an unrealistic. As if at the very beginning of the journey it was not clear that the Chinese with their cheap and no less effective options would win.

Here is a video of demonstration of their laser anti.komarina gun. It will come down for a beautiful movie, but how a real mass product for poor African users, for some reason, did not go.

There is also an opinion in reviews and reviews that in fact the ultraviolet does not attract insects at all, and simple light bulbs with warm light in this sense are even more effective.

However, this is what Professor Grustatkin Yu says about this.BUT. In his book “The course of general entomology”.

As you can see, for a mosquito there is still a difference of what light the light is radiated. That is why for the manufacture of such devices they made a choice in favor of ultraviolet radiation.

Also on store shelves you can find models operating in two light flows. For example, ZAPPLight bulbs.

They radiate both neutral white, with a brightness of several hundred lumens, and ultraviolet light.

The first is turned on for ordinary lighting, and the second at night. The area of ​​the territory on which insects will be lured depends on the size of the light bulb.

Mosquitoes fly to this light, touch the plates and die from a click of high voltage. This is a kind of electric chair for them.

You can use such lamps not only in the bedroom, but also on the street or on farms, in cowsheds, rabbits.

Do not forget that mosquitoes can be active varieties of any infection. True, this will already be a slightly different type of lamp, characterized by both sizes and shape.

Most often there are such specimens suspended to the hook.

Mosquito lamps: varieties and principle of action

Most people prefer warm summer evenings to spend friends outside the city with friends. In order not to sit in the house, many move into arbors for fresh air. A pleasant pastime can ruin mosquitoes, they like to profit from fresh blood. Bites cause severe itching, irritation. Salvation in this situation is a lamp from mosquitoes, playing the role of not only a trap, but also a light source in the dark.

Features of the device

The mosquito lamp is a device equipped with LEDs and a special grill through which the discharge of electric current passes. The joint exposure of light and current allows you to destroy blood.sucking insects instantly.

The lamp from mosquitoes for the street has advantages:

• High efficiency, the device not only scares away, but also destroys mosquitoes;
• Environmental friendliness, harmful substances are not distinguished into the air;
• During work, no outsiders or unpleasant odors appear;
• The product for mosquitoes works on sunny batteries, you do not need to use charging, just leave the lamps for the whole day in sunlight, they will be completely charged;
• Acceptable cost;
• A variety of models allows you to choose a lamp suitable for any radius of action.

Street lamps from mosquitoes have flaws:

• Effective only in the dark, during the day they do not bring benefits;
• When touching the light bulb, you can get a small discharge of current;
• It is necessary to observe recommendations that exclude moisture from the design of the structure;
• The equipment does not guarantee that a large number of insects will not fly;
• It is necessary to remove dead insects;
• To obtain a result, it is better to purchase several devices, place them at different angles.

The radius of the exposure of the electric lamps may not reach the places where the part of the people is located, in which case they become a bait for blood.sucking insects.

There are two types of devices for the street from mosquitoes:

Each type of mosquito lamps has its own principle of operation and effectiveness.

UV lamp

The design resembles a conventional lantern, inside of which a UV bulb is built, protected by a thin grill. It radiates blue, it is invisible to a person. But at the same time, for blood.sucking insects, it is quite attractive. They fly to radiation. A feature of the device is that it does not scare away, but destroys harmful insects.

• The light radiates ultraviolet radiation;
• Insects fly on waves;
• They are pierced by the discharge of electric current when it enters the lattice;
• Bloodsuckers die.

Do not forget that ultraviolet radiation together with electric current requires strict observance of operations of operation and safety. Ultraviolet trap for mosquitoes is completely safe for children and pets.

Insecticidal lamp

Insecticidal lamp is aimed at scaring insects. The design resembles a flashlight from mosquitoes, inside there are repellents built into the lamp.

• The lamp gives radiation, however, along with the light wave, substances poisonous for bloodsuckers are released;
• Insects are afraid of smells therefore do not fly close to a person;
• With poisoning, the bloodsucker instantly dies.

The device from mosquitoes does not work from an electric network, but on carbon dioxide or using cylinders with butan.

When using equipment of this type, it is worth remembering that poisonous substances are released into the air, so you need to be careful in the presence of children and pets. In addition, when working in the fresh air, the rapid consumption of the working solution against insects is noted.

Overview of the most popular devices

The use of mosquito lamps has gained popularity among consumers. The range of products is rich, all types differ in design and size. In addition, when used, all facts, the area of ​​influence, conditions of use should be taken into account.

Electronic means from mosquitoes are a miracle of technology, allow you to destroy bloodsuckers quickly, without harm to health. Each type has its own characteristics, relevant for use under different conditions.

Thermacell Scout Camp Lantern

Antiphonar, works with insecticides against insects. Allowed for use in rooms with an area of ​​not more than 20 kV. m. This is mainly used this repeller from mosquitoes on the street.

The device weighs 1 kg, has 4 light modes. It works on finger batteries, the kit has a cartridge with butan and 3 interchangeable plates. When the device is turned on, its action begins immediately. Distinguishes the required number of substances poisoning for bloodsuckers, which protects a person within a radius of 2.25 meters.

.

The lantern from mosquitoes and other flying insects for the street has advantages:

• Mobile, can be used anywhere, does not require connection to the power source;
• There are no substances harmful to human health;
• During work does not make noise.

One set of a plate and repellents is enough for a day.

Terminator

The terminator is suitable for flying and crawling insects. Produced in different variations, each is relevant for use under certain conditions. Some types work from the electric network, some using the battery.

• Option I. Operates on an area of ​​30 square meters. m, is turned on using a stationary power source. It has an angular shape. Average
• Option II. The device destroys flies and mosquitoes, operates on an area of ​​up to 60 kV. m. He has a concise and angular form of structure. Connects to a stationary power source, average
• Option III. The device combines the functions of the nightlight and trap for mosquitoes. Works on an autonomous power source, a radius of action 60 kV. m.
• Option VI. Intended for use on the street, has a protected case, thanks to this you can use during the rain. The design is decorated with decorative elements, the kit includes a brush to remove dead insects. Works on a network or autonomous power source.
• Option V. Powerful ultraviolet lamp works from a power source. Intended for use in the room, since there is no protective visor on the grille. Action radius of 40 kV. m. Average

When you need adjustment

It is necessary to adjust the ignition system so that the fuel is ignited at the right time in the combustion chamber.

Important! Когда поршень сжимает горючее и практически достигает мертвой точки сверху, в свече возникает искра. Further, when it passes the maximum upper point, the fuel is lit up, as a result of the explosion, energy forms and directs the piston down.

If the flywheel is shifted to the shaft relative to its original position, the fuel is ignited faster than the piston overcomes the upper dead point. As a result of this, the piston moves back, and the crankshaft rotates in the opposite direction. You can determine the early fire of the fuel by a broken launch cord, a broken starter node or other breakdowns.

Sometimes ignition is late. The piston compresses the irreparable fuel, and then goes down, and only then the spark forms. As a result, the engine either does not work or its power is reduced, and the speed is gaining much slower.

Typically, a flywheel with magnets is installed in an ideal position, as if coordinated with the operation of the piston, and in order to avoid displacement, it is carefully fixed. This allows us to say that an incorrect installation of a part is impossible. But if the shift of the flywheel is a confirmed fact, then it is a failure or accident. Thus, the installation of the moment of the ignition is not required, since problems with early or late ignition of fuel happen very rarely.

Important! It is very simple to regulate the ignition system. There is no need to calculate the ignition angle angle. The maximum that you need to do is to properly set the gap between the flywheel and the reel.

A Chinese lawn mower is not started.It is interesting.

Spare parts for Chinese motorcycle do not start Chinese

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.

How to correct the ignition coil on a trimmer for grass

Internal combustion engines are installed not only in cars or bicycles. They are widely used in various tools, for example, in chainsaws or a trimmer for grass. In the case of faulty, incorrect launch, it is often enough to set the correct gap between the flywheel and the ignition coil.

Attention was found a very popular way to reduce fuel consumption! Do not believe? A mechanic with 15 years of experience also did not believe until he tried. Now he saves 35,000 on gasoline during the year! Read more “

Not so complicated car by itself. But it is important to have at least some knowledge to find and eliminate any shortcomings.

Modern electronics developed so much that it made a revolution in the world of tools. The chainsaws of our time are light, but powerful, equipped with electric ignition systems.

In recent years, the ignition systems of chainsaws have been cam type. This had many shortcomings: he was heavy, complex, expensive and much, much more. The main drawback of archaic accounting ignition (software) is the complexity of the plant. Some models of accounting (soft) saws could not produce enough sparks for flash at a speed of crankshaft rotation.

Modern accounting software practically no problem. The models drank light and very durable, the coil is more skillful and takes a smaller part. But there are problems, but in most cases they can be eliminated with your own hands.

Consider the main types of malfunctions of chainsaws associated with the flywheel and ignition system.

One of the most common problems of modern chainsaws is the lack of spark ignition. This is directly related to the gap between the cylinder and the flywheel.

How to set up input blades, Partner, McCullock, Jonshed, Magneto gap

The most common installation malfunctions are always associated with the internal combustion engine. Problems arise in the ignition system, the fuel fuel module and the internal components of the engine itself.

As for the other components of the chainsaw, the malfunctions arise due to the failure of the brake mechanism, the lubrication system, etc.D.

If difficulties with the launch are associated with the engine, then in most cases the following symptoms are observed

• The engine does not develop sufficient power;
• does not start at all;
• begins, but quickly stops;
• unstable work.

As before, experts advise identifying the causes of defects by eliminating. In other words, it is necessary to go through the entire chain, diagnosing each node, each link.

NW non-working saw is a common reason, due to employment, the tool engine does not start. In most cases, it is recommended to start a search for a problem from this place.

• First, check the spark plug, carefully disconnecting the spark plugs from the head and twisting the candle from the nest with a wrench;
• The second step is to check the spark of ignition by twitching the starter with the cap of the ignition wire, worn on the spark plug;
• Our article is devoted to checking this gap (more below).

A faulty spark plug indicates a faulty spark plug. Wet spark plugs for ignition of the fuel-air mixture indicate that there is actually too much fuel in the system, the carburetor is incorrectly adjusted or there are problems in SZ.

Check the spark plug only after drying it. T.e. Wipe it well with a napkin, dry the internal combustion engine, shut up the feeder, and then run the starter several times to release excess fuel consistency.

Then the spark plug is installed in place, and the client receives another check.

In general, the spark plug can tell a lot about the entire ignition system. If there is a dark carrier on the spark plug, this indicates a malfunction in the gas supply lines. Either the ratio of gasoline and oil is wrong, or the carburetor needs to be adjusted. Sometimes it is also caused by poor oil.

The polluted light of the ignition is cleaned of dark carbon deposits with a needle, as any other sharp object is called. Then the electrode is cleaned with sandpaper until the iron glow appears. The sparking returns to the place where it should be checked again.

Next step: checking spark. The sparkmer’s saucer is fed to the cylinder, the starter is launched. If a bluish spark is visible at a length of 2-3 mm, this is normal for our client. Skarer passing 0.5-1 mm is already considered a malfunction. Maybe there is no spark at all, this is also a big problem. Perhaps the case is a faulty wire.

This leads us to the topic of our article. The chainsaw may not be launched due to the gap between the ignition and the magneto Makhovik. This very gap at the moment is 0.2.7 mm. This is easy to check: there is a special seal between the flywheel and the flywheel. If he sits normally, slightly free and tight, then the gap is normal.

The flywheel is round, and it is impossible to check it using the gap meter. It would be better to check the backlash with a special device, but it is not often possible to buy it. And to take a template that is expensive, not everyone can do for a one.time implementation.

But instead of the overseas template, use a cut strip from a 1-2-liter plastic container for juice.

A homemade template looks as follows:

Advice. It is recommended to cut a plastic strip in places where there are no embossed tubercles.

Magneto, Babbin, module. this is a coil of the ignition coil. This may not be related to the ablous of the tool, and the reason may consist exclusively in the gap or in some other way. Sometimes, however, the cause of the malfunction is the coil itself.

To check the coil itself, as in the case described above, use the method of excluding the elements from the chain. Or, speaking differently:

• Visually check the condition of the body for the presence of cracks and other visible defects;
• Check the cleanliness of the current compounds of individual components and parts;
• diagnose the isolation and serviceability of the armored pipelines, reliability of the mount, the absence of rust, etc.D;
• Visually assess the condition of the spark plug nest;
• Check the serviceability of the spark plug;
• diagnose a circuit breaker, which is especially important for Chinese.made chainsaws.

Malfunctions and elimination of problems

Electric and gasoline trimmers for grass have general malfunctions and defects. In the case of equipment with an internal combustion engine, this is:

• problems with the carburetor;
• Engine failure;
• Problems with the fuel system;
• failure of the gearbox, starter, muffler;
• sabo;
• air filter malfunction;
• Problems with ignition coil.

Electrical equipment has certain units:

In case of simple problems, you can repair a trimmer for grass with your own hands.

Why is your trimmer not starting for grass

The most common reason that the machine does not start is the use of low.quality fuel. The choice of gasoline of the brand below the AI-92 can lead to damage to the machine. If the used fuel of good quality, look for other reasons. For this, all nodes and systems are carefully checked. The following components must be checked:

The device may not turn on after a long period of inaction. Before starting a trimmer for the grass, carefully read the operating instructions. There are solutions to many problems.

If the trimmer for the grass stops when you press the gas pedal

There are several reasons why the trimmer for the grass stops on the throttle:

• The first reason is the malfunction of the carburetor.
• Flaw valve clogging.
• Clotting of the check valve.
• The weakened and unimportant hose of the carburetor or the weakened fuel intake hose.

To avoid the problems described above with the mower, carefully inspect the condition of the machine and its components. Timely cleaning and washing of the car and its parts will extend the life of the machine.

Starter malfunctions

The most unpleasant starter malfunction occurs when the cable breaks off and wound on the flywheel during engine operation. As a result, the spring may break, and the pulley is torn. In this case, only a complete replacement of the part will help. This type of refusal is rare. frequent cases are:

In this case, the starter is easy to repair on its own. The manufacturer has prepared a step.by.step instruction for this.

Repair of the gearbox

To maintain a gearbox of an electric braid for grass in good condition, it must be lubricated in a timely manner. Otherwise, the gears can be quickly worn out, and the transmission module can jam.

The main malfunctions in the transmission of a trimmer for grass

• Strong heating of the transmission node due to the use of a small amount of lubrication or its absence;
• The shaft was jammed due to rotating worn bearings;
• Staggering or slipping the shaft of the gearbox assembly due to damage to the housing;
• The inability of the output shaft rotate along with the disk due to wear of the teeth on the gears.

Most of the gearbox failures are caused by the destruction of bearings.

This is due to the use of poor-quality lubrication or its absence. Another reason for the breakdown of the gearbox is when a trimmer for grass is used at the limit of its capabilities and extraneous objects get inside. To replace a faulty bearing, it is necessary to disassemble the gearbox.

Features of electric models

Models of trimmers with an electric drive from the network have several main blocks

Each electric trimmer for grass has certain disadvantages. In the mechanical part, they depend on the fishing line used as a cutting element. Reasons for the termination of work:

The electric part of the braid braid can be found using the tool:

To solve this problem, use a cutter.

• damaged power cord;
• problems with an outlet and fork;
• damaged control handle;
• The starter solenoid burned, it is necessary to replace the engine;
• Damaged contacts can be repaired independently using a soldering iron.

These are the main reasons why there may be no spark on the trimmer.

What kind of ignition gap should be on the chainsaw?

The average is considered to be a distance equal to at least 0.2 and not more than 0.4 mm. In case of violation of the correct gap, the base ignition system will not be able to generate the spark required for timely instant ignition of the refueling fuel mixture in time.

The candle is universal. Used in chainsaws and motorcycles of all models. Candle thread diameter 14mm. Gap between electrodes 0.8 mm.

What is the ignition gap on the chainsaw of Stihl 180?

Pay attention to the gap between the flywheel and magnets. If the magnets are absent or do not correspond to the original form. this suggests that the destruction of the flywheel has begun and it should be replaced. The optimal gap between the flywheel and magnets is 0.3-0.5 mm.

Connect the tester or control lamp to the “mass” and to the output of the ignition coil, connected by brown-red (usually not necessarily) wire with the terminal “1” of the switch. With a good switch, the tester arrow, included in the voltmeter mode, will deviate, and the lamp will light up (the ignition is turned on).

Diagnosis of the technical condition

Diagnosis is carried out when performing the following order of actions:

• The first stage is the supply of a high.voltage cable to the conclusion with the stress.
• At a distance of about 0.5-0.7 centimeters from the device body, the second end of the cable is constantly held.
• Preservation of the position in the wire. Next is a sharp turn of the rotor along the rotation. The spark should slip as a result of such a movement, if everything is in order, Magneto is adjusted correctly. If the spark is absent or too weak, it is likely that the installation requires a check for faults. If necessary. adjustment is carried out.

Frequent malfunctions, their repair

Here are just some of the problems that the owners of Magneto can meet most often:

• Contrices during sparking. This situation has several reasons, ways to eliminate problems. Possible problems include: contacts are burned, oxidized; The adjustment by the gap is violated; the lever pillow at the breaker was worn out; The condenser element turned out to be broken. If the element is out of order, then its complete replacement is carried out. Когда проблема в зазорах – проводят их дополнительную регулировку. Contacts also change or are completely cleaned. How to set up magneto, it is told further.
• The complete absence of a spark. Often this is due to the fact that transformer wiring broke off, there was a closing to the mass or an insulating layer made its way, which is supplied with a high-voltage cable. When problems appear with the transformer, the node must be mandatory to replace. You can eliminate the short circuit or change the cable when a breakdown occurs at the isolation.
• A punched capacitor is the most likely reason for the appearance of too weak sparks. In this case, the detail is also subject to mandatory replacement.

Candle and armored vehicle

It is recommended to abandon the caps used for armor pipelines. It is better to use a clip type “crocodile”.

The armored vehicle itself also requires additional verification. This applies to two elements:

Detail scheme

Capacitor

It is needed so that the contacts do not burn too much. Consists of two heating and isolation, the role of which is usually played by foil. Everything rolls into one roll, placed inside the case. In some cases, if the housing is damaged, the capacitors can be adjusted on the emery

It is important that the structural parts do not overheat during operation. Magneto setting up after that will not help

Be sure to read: PD-10 starting engine: characteristics and device

Sometimes it is recommended to put two capacitors at once, then the operation of the mechanisms will be more reliable and stable.

About the contacts of the interrupt

If they have become faulty, the first recommendation is to clean the surface with a special flat abrasive plate. Work is also performed without problems with a flat file, which has a small notch. Cleaning with sandpaper, with glass paper will not give the necessary result. The contacts wear out too quickly, in this case, do not get a flat surface.

Contacts from time to time also require cleansing from the raid, regulation of the clearance between the details. The main thing is not to lose any part when disassembling. The contacts of the contacts are subject to malfunction or straightened in the opposite direction.

Coil or transformer

It is easy to repair the magneto tractor for such details. The same part of the engine rarely fails, it can uninterruptedly work out for a long time. If the part has become unusable, then it is necessary to replace it with exactly the same, but the working model.

Rotor

The main thing is that he does not crumble, does not break through during operation. From time to time, the rotor is able to demagnetize. If the part really turned out to be spoiled, then it is changed. The main thing is not to forget to remove the fragments of the metal, sometimes they remain inside the magneto body. A separate inspection and lubricant require bearings.

The ignition adjustment procedure

Setting the ignition system is performed simply and identical to different models of trimmers, whether it be Stihl FS55, Al-KO Sun 4125 or other lawn mower. First you need to remove the casing from the engine, having previously removed the fixing fixing. This stage of disassembly may have differences on different models of motorcycle (described below). Next, you need to partially unscrew the fasteners fixing the magneto, and turn the flywheel so that the magnets are at the top.

To make the optimal gap between the coil and the magneto, you must use a special template. It is impractical to buy it for a single use, therefore, as an alternative, you can apply a business card or a small calendar, as well as a paper sheet A4, folded four. A strip carved from a plastic bottle or other improvised materials that have the necessary thickness is also suitable. The optimal distance is usually indicated in the user guide. The selected item must be placed between the magnets and the coil.

Then the coil will be pulled to the flywheel with a magnetic field. Holding the magneto in this position, you need to tighten the fixing fastener, and then pull out the business card. After that, you need to scroll several times a flywheel to make sure that he does not touch the coil at all. The process is over. the ignition on the motorcycle is exhibited. Read more the process of adjusting the trimmer ignition system can be studied on the Internet, where many videos are available to this topic.

Operating principle

When the flywheel rotates, an electric current is generated in Magneto, which creates a spark on the spark plug at the moment when magnets pass under the coil.

The second method

If you use the tester, there is no other way to check

At the same time, it is important not to touch the cylinder electrode, otherwise the coil will be damaged

• It is necessary to remove the cap from the spark plug. You should not unscrew the candle, as this will save compression.
• Then you need to choose a nail with a remote hat and tightly insert it into the cap.
• Further, the cap with a nail should be reliably tied to the cylinder by the dielectric. In this case, the electrode should be at a distance of 5.5-7 mm from the cylinder body, but do not touch the mass.
• Then the starter needs to simulate the start of the motor with the ignition button. In this case, it is required to carefully monitor whether the spark will appear, and try to determine its color.

Important! A strong spark of white or with a blue shade indicates in favor of the serviceability of magneto. If it is weak, as well as orange or yellow, magneto is damaged

There is one important point that needs to be taken into account when diagnostics: uninhabited magneto in any state can form a powerful spark. However, if it is faulty, then, heated, stops creating a current, and the trimmer does not start for the grass. Later, cooing, the coil again returns to the working level, the unoic tractor turns on and for some time works at idle or under load, until the magneto temperature rises again. In this case, the part needs to be changed for a new.

On a note! In a number of situations, the problem with heating does not occur due to the fault of the coil, but due to the spark plug. This means that the test must be subjected to both parts.
