The causes of breakdowns of gasoline and electric trimmers

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

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

Weirdest Things Stuck Up Exhausts and Sound l Cars and Engines

Damage of gasoline trimmers

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

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

Malfunctions of electric trimmers

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

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

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

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

Why is the gasoline trimmer not starting for the grass

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

Fuel tank (fuel quality)

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

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

Candle and candle channel

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

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

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

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

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

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

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

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

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

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

Air filter

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

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

Fuel filter

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

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

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

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

How to remove and disassemble a coil

Before proceeding to the process of replacing the cord, users of trimmers need to remove and disassemble the coil. Consider how to do it.

The mowing head of a trimmer for grass consists of several parts: a casing, springs (not in all models), bobbins with a cord and cover.

Attention! Before proceeding with any actions to maintain an electric unit, it must be disconnected from the network.

Trimmers most often use 2 options for fastening a mowing head.

Option

To remove the head of the trimmer for the grass, it will require its complete disassembly.

  • To remove the lid covering the inside of the head, it is necessary to press on the latch (latches) located on its two sides.
  • Removing the lid, you will see the spool that must be removed from the body. In some coils, a spring is installed under the bobbin, which must be carefully pulled out so as not to lose it in the grass.
  • Removing the bobbin, in the center of the case you will see a screw with a slot under a cross.shaped or flat screwdriver. It is possible that there may be a bolt under the hexagon or nozzle “Asterisk”.
  • Using a screwdriver, choosing the necessary bat (nozzle), you need to unscrew the bolt (counterclockwise).
  • After extracting the fasteners, take up the part of the part and, shaking it in different directions, remove the gearbox from the shaft.

Option

In this version, the head is twisted onto the gear shaft. To remove it, you need to fix this shaft. To do this, in such trimmers, for example, in the Huter and Champion devices, a hole is provided through which you can insert either a thin screwdriver or a metal rod.

So, to remove the bobbin, take 2 simple steps.

  • Insert the screwdriver into the hole and stall the shaft.
  • Take the head of the head and start twist it clockwise. It should be twisted in this direction for the reason that the thread cut on the shaft is left.

Field winding algorithm

Depending on which model of the trimmer for grass is used, the type, thickness and length of the fishing line is selected. The diameter of the cord can be from 1.2 to 4 mm. It is not difficult to guess that the thicker you will refuel the cord, the more rigid and thick grass it is able to cut off.

In most cases, a universal fishing line for a trimmer with a diameter of 2 mm is used.

In order to find out which line diameter can be used on your mower, there are 3 ways.

  • View information about the thickness of the cord in the instructions for the apparatus.
  • Look at the squash itself. It can be given information about possible fishing line diameters.
  • Insert a fishing line for a trimmer into the output. If it passes into it without difficulty, then the cord of such a diameter can be used.

The fishing line for a trimmer is wound on a coil in a mowing head. Therefore, first it needs to be opened (this was mentioned above). There are 2 methods of winding the cord.

The first way

To correctly determine how many meters of the fishing line are required for a specific coil, it is necessary to wind it on the bobbin so that the skein does not exceed the diameter of the sides. If the fishing line for the trimmer will look out beyond the edges of the coil, you cannot insert it into the casing. After you have decided on the length of the material, it must be tucked in a bastard, so do the following.

  • It is necessary to fold the fishing line for double so that one end is 10-15 cm longer from the other.
  • Please note that the bobbin is divided into 2 parts by the central side, from which charging begins. Find a groove on it and insert a cord into it, bent twice, putting a slight effort.
  • It is very important to determine in which direction the fishing line for a trimmer is wound on the reel. If you look closely, you can find an arrow on the bobbin or an inscription with an arrow indicating which direction the winding should be carried out. There are times when there is no arrow on the coil. In such a situation, you can look at the arrow drawn on a mowing head, and wind the cord in the opposite direction.
  • Winding should be carried out carefully, a turn to the turn, with maximum thread tension.
  • After laying the cord is completed, you will need to fix it first the short end of the fishing line, inserting it into the groove suitable in diameter on the side of the coil.
  • The second end, the one that is more authentic, is attached into the groove on the opposite side of the squash.
  • After fixing the fishing line, cut its ends, leaving the allowances about 10 cm.
  • Next, it is necessary to install a refueling coil in a mowing head. To do this, alternately inserting and pulling the thread into the weekends of the head, place the bobbin in the casing, after which, by applying the required force, pull the fishing line for a trimmer from the fixing grooves and tighten it.
  • Now you can put on the lid and fix it with the help of latches.

The second method

Some coils provide a second method of fixing the cord: you can charge 2 sections of the thread, instead of one folded in half. Fishing line replacement occurs according to the following algorithm.

  • Before changing or charging a new thread to the coil, determine how many meters it will be required by the way discussed above.
  • Bend one end of the cord in the form of a hook.
  • Find a hole intended for fixing the fishing line at the bottom of the bobbin, and insert the end of the thread bent by a loop into it.
  • Wrapping the cord is required according to the direction of the arrow to the required level not exceeding the diameter of the coil.
  • Do the same actions for the second cell of the bobbin.
  • The assembly of the head is no different from the method that was given when the refueling of the bobbin was considered folded by half a piece of fishing line.

There is a very simple and quick way to replace the fishing line for motor.cuts without disassembling the mowing head, which you can see this video.

The ends of the cord sticking out of the holes in the casing can be cut to the required length, already when the part is installed in the trimmer. You can do this in two ways:

  • By turning on the trimmer for the grass (when rotating, the ends of the fishing line will part on the knife, fixed for these purposes on the protective casing);
  • Cutting the extra ends with scissors so that they do not touch the casing body.

The second method is used if I had to put a large diameter cord, and a trimmed knife cannot shorten it.

If the thread was charged into a mowing head, but the length of the protruding ends of the cord is insufficient, then before starting the device they must be lengthened. this applies to the head with manual adjustment. However, there are cases when using a semi-automatic mowing head, when, due to the insufficient length of the protruding ends of the cord, they do not automatically lengthen. In this case, it is necessary to turn off the unit (on the electric device you need to pull the fork out of the outlet), manually press the button located at the bottom of the part, and stretch a little fishing line. After this procedure, the cord will be able to advance again thanks to centrifugal strength, if you put the maximum spindle speed.

No matter how thick the fishing line for the trimmer you should remember: in order not to constantly interrupt the work and do not change the cord, you should avoid areas where a working tool can touch hard surfaces (stones, borders, thick dry branches, etc.D.).

Trimmer for grass does not gain momentum, what to do?

Probably, the users of the braids noticed that a couple of weeks after the start of the apparatus, he begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system in the form of shock absorbers sewed between the engine and the bar was installed. However, sometimes even she does not help from strong vibration. A prerequisite that powerful vibration occurs in the trimmer, you will like a small amount in other words, in other words, the complete absence of lubrication on a hard or flexible shaft located in the snot of the rod of the apparatus.

A change in the lubrication of a hard shaft occurs in this way:

  • unscrew the gearbox located at the bottom of the bar;
  • After removing the gearbox, the end of the shaft is visible, for which it is necessary to pull the part;
  • after extracting the shaft, it must be abundantly lubricated with a special lubricant “Shrus-4” or ordinary-“Litol-24”;

Ford Explorer Engine Seized. Fix!

  • Apply a small amount of grease on the shaft and moderately spread it over the entire length of the part, including the slots at the ends of the table (if they worked, the shaft will have to be replaced);
  • After lubrication, stick the shaft back into the bar and put the gearbox in your former place.
  • unscrew and remove the mowing head;
  • remove the bar from the electric motor by unscrewing a couple of bolts;
  • remove a flexible cable from the bar;
  • Lubricate the cable with grease over the entire length.

This is done like this: at first you need to lubricate the end of the cable, and then stick it into the bar, then, during the advancement of it inside the pipe, you should apply a lubricant to the part and moderately distribute it on the surface. Then stick the bar with a flexible shaft into the electronic engine and fix it.

Trimmer for grass Elmos is not gaining momentum?

For which the design is intended when the lubricant did not help, and the vibration continues to appear, the flexible shaft will need to be changed.

The trimmer for grass is overheated for many reasons:

  • Gasoline has not the same octane number indicated in the annotation to the aggregate;
  • The proportions of gasoline and oil are not observed at the time of the manufacture of fuel consistency;
  • A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
  • The trimmer for the grass works above the time due to the annotation;
  • A low.power trimmer is used for grass on a thick and hard grass, the device works with overload and heats up rapidly;
  • shifted towards the bar, the cassette lid clutched differently.

The latter occurs if you install a mowing head inappropriate for this unit, or when the axis shifts inside the bar. These configurations make it difficult to rotate, the load on the engine increases, and its overheating occurs.

We put on a belt

Without a belt, the operation of a trimmer for grass is impossible: it provides redistribution of voltage from hand to shoulders and spine, and helps optimize the return. Put on the belt on the already assembled device when the bar is in the engine’s groove.

The belt itself is attached to a metal loop, which provides dense fixation even at the maximum load. The belt mount design is the same in all models and does not require additional manipulations when installing. It is enough to enter the loop into the above hole. and the fixation will be provided.

Just putting the belt is not enough, you need to debug it for yourself. The belt setup occurs depending on the growth of a person. Make sure that the belt is stretched correctly, you can at work. If the shoulders and arms do not get tired enough in the process of mowing, and vibration does not cause unpleasant sensations in the muscles, then the belt is set correctly. If your hands are quickly tired, you should turn off the device, weaken the belt, and tighten it to your height again. This procedure needs to be carried out until the trimmer for the grass lies exactly “on the arm”, and on the weight the length of its rod will be optimal relative to the surface.

Important: it is not recommended to use a trimmer with a poorly tightened belt, it can be traumatic. Such a belt risks slipping from the shoulder and get under the feet. And hands without redistribution of efforts with a belt get tired much faster.

It is quite easy to adjust the belt length with the help of a loop: for this it is enough to tighten it to reduce the volume, or weaken to increase the length.

trimmer for grass in action

So, the preparatory stage is over, it’s time to start work. Where to start? How to use all the capabilities of the device correctly? Of course, you can simply start work and learn the whole method of trial and error, or adhere to simple, but correct recommendations and get a wonderful effect after the first mowing. There are nuances everywhere, whether it is a haircut of a lawn, a saw of bushes with a disk or a mowing of grass for hay. You should start from the simplest.

How to cut the lawn so that it turns out to be even

The lawn implies an open even area that excludes some large landscape irregularities (pits, hills). Of course, snags and stumps should not stick out of the ground. their uprooting should be borne in advance. It is best to plant a place under the lawn with soft varieties of grass, which are good to mowing. In this case, you will spend much less effort.

  • Experts recommend dividing the entire area into small squares and mowing along them, moving from one to another clockwise. In this case, the grass that you mowed always remains on the left, and will not interfere with further manipulations with the trimmer.
  • If you need to mow “under the root”, then the angle of contact with the surface should be at least 30 degrees. With this technique, the device is practically in contact with the surface with a cutting knife.
  • There is an opinion that in order to give the lawn of the completed type, it must be mowed by a lawn.type lawn mower. This is partly so, but having adopted, you can achieve good results and with a manual trimmer. To correct the shortcomings after the work of a trimmer for grass, it is also recommended to use hand scissors for grass.
  • The lower the fishing line for the trimmer will be, the more even the lawn will be. Leaving the grass higher, it is likely that in different places it will be molested in different ways. This is due to the fact that the trimmer itself for the grass is not fixed on a horizontal plane, which leads to irregularities during the reciprocating movement performed during operation.

Kosim under hay

Harmity for a village resident is a necessity. this is animal food in winter, fertilizer and covering material that protects the landing from cold weather. Of course, with such a versatility of use, the question arises about a man’s advance harvesting. Kosba for the workpiece differs from the usual aesthetic cleaning of the perimeter in some features.

  • For example, in order not to grind the mulch, you need to mow under the root, lowering the bar with the disk as lower.
  • The bums should be outlined in which the mowed grass will go to. this will help to avoid piles and crowding. In addition, at the end of work, it will be easier to clean.
  • Another very important point is to shield large weeds. For example, a formed bush of a burdock, which not every knife is able to cut. If such a large weed is found on your way, you should bake it in a circle and continue to work. When the work around the perimeter is completed, lonely sticking weeds will remain on the site, which are easy to remove with their hands, moreover, they are not mixed with grass.
  • The main thing in the span for hay is to leave the length of the grass, not allowing it to lose shape. Otherwise, the resulting mulch can only be used as covering material.
  • The width of the mowing should remain strictly fixed, t.to. It is necessary to remember the average size and length of the workpiece.

Some experts recommend using a fishing line for a trimmer when running for hay, but this is not always right. Firstly, usually the grass in such a section is high, moreover, its base is a more dense and formed. The use of fishing line will increase engine wear, as it will have to work at high speeds. Of course, this will affect performance. Secondly, a fishing line for a trimmer is simply not provided for such loads. Using this material, you risk not only the fishing line itself, but the whole mower.

The best option is a disk designed for shrubs. it is designed for increased loads. In addition, the high grass is rude at the base, and it will roll the blade most productively than a fishing line designed for soft, silky lawn grass.

There are additional devices for navigation by a trimmer for hay, but all of them are unofficial modifications. In other words, homemade improvements, the use of which is extremely not recommended, t.to. The behavior of the device in unexplored conditions can be unpredictable. Following simple recommendations, you can quickly gain the necessary experience and harvest hay in large volumes.

Spinning high grass

It is not difficult to cut high grass. The mowing occurs immediately in two directions. First to the left, then to the right (first passage), cutting off the top. Then in the opposite direction, but already lowering the bar with the blade to the necessary level. In this case, the grass, which was squinted, remains to lie on the left side, which is very convenient when the subsequent collection. It happens that the weeds grew too much and plentiful. In this case, several movements may be needed to the right and left, most importantly, adhere to the correct pattern.

With several movements of the fishing line for a trimmer, it is consumed much faster, but in some cases it may be necessary to get to the base of thickets into which it is impossible to cut through. If necessary, a fishing line for a trimmer can be alternated with a knife. If difficulties arise, and the productivity of the device has decreased, it will be enough to simply replace the consumer and start work again.

Do not try to pump high grass immediately under the base. this can lead to difficulties. For example, a long stem can be wound on a fishing line for a trimmer, which will lead to a long.term unplanned stop.

Repair of lawn mowers of electric

Many owners of lawn mowers sooner or later face technical problems of this technique. Often problems arise after several seasons of active use or after the equipment spends the winter in a cold unheated room. And it doesn’t matter what the engine is installed: high.quality Japanese or simple Chinese, over the years it will still begin to fail. But you do not need to be upset and rush to the service center. many breakdowns can be eliminated on your own.

The traditional “pushing” technique has long received knives from electric engines, which significantly facilitated the process of work. This type is still very popular, especially among those who want to get a beautiful lawn, but nothing can be compared with the relative novelty of the domestic market. rotary mowers that easily cut off even the highest grass.

Rotor.type mowals are powered only from electric networks, and cylindrical ones. both from the network and from batteries.

Both types are represented by different modifications. Gasoline braids will not be considered separately, but the proposed options for eliminating breakdowns in most cases are identical. You always need to have at hand a manual or apply for advice to professionals if there are problems in care or use.

Cylindrical braids

Their composition contains spiral knives, the totality of which resembles a cylinder. A large toothed pulley placed at one end sets the belt (in some cases, the chain), on the other hand, is worn on the second, a small pulley attached to the engine shaft. The engine can set in motion and a rink that moves the equipment on the ground.

  • Switch lever.
  • Emergency shutdown button and protective lock.
  • Switch.
  • Filter.
  • Air intake grille.
  • Gap regulator between knives.
  • A motionless knife.
  • Knife cylinder.
  • Large toothed pulley.
  • Drive belt.
  • Drive pulley.
  • Lever that regulates the height.
  • Electric motor.
  • Rink.
  • Power cable.

When the cylinder rotates, the knives press the grass to a motionless knife attached to the cylinder, thereby creating a cutting effect resembling the principle of action of scissors. Any damage, even the most insignificant, wear, improper fixing of knives make the operation of technology less effective. The height of the cutting of the grass changes after adjusting the position of the rink or wheel located in the front or rear of the knife cylinder.

Rotor mowers

They have one knife horizontally fixed to the engine shaft. Rotations with high speed make it possible to cut off both grass and other plants. Some models have disks with replaceable plastic knives. they are easy to replace if necessary.

There are wheels in separate mowers, but most models move on air cushions. Here the engine rotates the impeller, which distillates the air masses under the hood. the lifting force is created. Metal knife is placed under the impeller.

Rotor.type mower is made up of:

If we talk about mowers on air pillows, then remote washers are installed above the knife that regulate the height of the grass mowing.

As an alternative solution, you can simply turn the disc with plastic knives to increase or decrease the height of mowing.

In all types of equipment, there can be containers for collecting herbal scraps.

Some gardeners give preference such that it cuts the grass as finely as possible and leaves trim on the lawn as mulch.

The value of emergency switches

All modern lawn mowers have safety systems that will not allow you to start work if both handles or a combination of the shutdown lever with the protective blocking button are not involved at the same time. The switch is turned off as soon as the lever is lowered.

Working with electrical engineering, you need to take care of your own safety. Refuse the use of equipment if you are very tired and cannot be careful. Before the plug in the outlet, check in what condition is the power cord, check that all the devices for protection, knives and fasteners are securely fixed. Wipe the cord completely, lay the excess near yourself along the edge of the lawn from which you will start.

Before work, check if there are any small objects (pebbles, bones) in the green zone that can ruin the knives or be thrown back with the same knives with great force. Keep the cord on your shoulder, grab the handle with two hands. In the process, make sure that the cord is always behind. Before adjusting the height of the mowing, the equipment must be disconnected from the mains.

After completing the work, pull the fork from the outlet, remove the remaining grass from the knives and the air intake grille. Wipe the body with a dry rag. With a spatula made of plastic or wood, remove the mulch from the bottom of the mower near the air cushion. At the end of the season, thoroughly clean the lawn mower thoroughly, rub the knife with an oil rag. Do not forget to lubricate the bearings and regulators. Also check the condition of the power cord: if it is strongly worn, order a replacement to be prepared for the beginning of the next season.

The most common breakdowns

Any technique sooner or later fails. It is important to know how to repair mowers, because not in all cases you need to contact the service center.

The braid does not cut the grass

In most cases, the cause is dumb or severely damaged knives. To achieve the best results, just change the knife every year. Choose a knife suitable for your model. When the knife is swept away, you can sharpen using electrofig or file. When sharpening, be sure to use goggles and gloves. Angle of sharpening on both sides. about 30 degrees.

Simple sharpening devices can be purchased in stores. Before installing them, it is necessary to turn off the mower from the network and adjust the cylinder positions in such a way as to highlight the maximum cutting gap.

In cylindrical braids, the gap between the knife and the cylinder should be less than the thickness of the sheet of paper. Some of the most modern models have built.in regulators with notches. In other cases, you will have to use keys and screwdrivers to carry out the necessary adjustments. Follow the uniformity of the gap along the entire length of the cylinder. To check the adjustment, insert a sheet of paper between the cylinder and a knife, slowly rotating with your hand. Gradually adjust on both sides until the paper begins to cut purely at each point of a motionless knife.

It is difficult to move the mower

  • When the mower hardly moves along the lawn, you may try to remove too high grass and you will have to adjust the level of mowing. When seizing rollers or wheels, they need to be inspected to make sure that there are no scraps of grass and garbage. Most likely, they need to be removed and cleaned.
  • If an interference for air is formed, then the lifting force will decrease on the mowing air pillow, and it will become difficult to move it. Air lack leads to overheating of the engine. Disconnect the power and remove the remaining grass from the air intake grilles.

The technique does not turn on at all

Long and wet grass can easily block the knives. Pull the fork from the mains and with the help of a wooden object rotate the cylinder to the other side of the knife until the movement becomes free. For gasoline mowers, this technique cannot be used.

A belt that provides the operation of cylindrical lawn mowers, wears out, stretches and can break through. Remove the belt cover and check, there was a gap or belt just jumped off. Unscrew the mounting screws and move the small leading pulley to a large cylinder pulley. Put on a new belt on a small pulley and slowly rotate the big one, gradually putting a belt on it. Push the pulley to the side to stretch the belt, then tighten the screws.

Before installing the lid, be sure to check the belt tension. the degree of bending should not exceed 4 mm (the indicator may fluctuate slightly depending on the model, detailed information is contained in the user guide).

Gap in the cord

With every use, you unfold, move and turn the cord. This can lead to a break in the internal conductors. For many models, the cord is connected to the screw terminals, which makes it possible to quickly check it and replace it. If double isolation, a two.core cord is connected.

Other models use clamping contacts that facilitate the replacement. Disconnect the power, separate the plastic cover. When you unscrew the clamping bar, pay attention to the connection of the cord to the switch to comply with the polarity of the connection (wire color).

In order to disconnect the cord, insert the hexagonal key into each of the holes in which the conductors are placed. to free the clamp and the conductor. Check where the gap has formed.

If necessary, connect a new cord: twist together all individual wiring of each core, then insert the twisted ends into the corresponding terminals. Pull slightly to check the connection. Then install the clamping bar, the cord bushing and the circuit breaker cover.

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:

  • 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.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

The best result will be required to comply with some rules for laying the lawn and high.quality raw materials. Therefore, in the store, before buying, you need to make sure that the rolls are really high.quality.

The parameters of the rolls are approximately the same: 2 x0.4 m, a turf 2 cm thick, the height of the grass is not more than 6 cm. To check the quality, you need to expand the roll and make sure:

  • lack of weeds and pests,
  • uniform height of the lawn,
  • absence of voids and prophashin,
  • strength and density of the root system of plants.

The variety of the lawn should be taken into account: park or sports. Depending on this, the lawn will be shade.tolerant, drought.resistant, resistant to trampling.

Trimmer repair for grass for grass with your own hands: Frequent causes of breakdowns

A trimmer for grass may fail when working in conditions of increased loads. This situation may arise when the processed area is overgrown with high grass.

When working in such areas, the engine may fail, a breakdown of bearings occur, as well as the coil of the electric ships to collapse. When working in rainy weather or in conditions of very fog, a trimmer for grass can “burn” as a result of a short circuit formation.

Damage to this electrical device can occur as a result of frequent use. If the household appliance is used in this mode, then after the development of a certain number of motorcycles, it will be necessary to carry out mandatory repair and preventive setting of many parts of the electrical device.

Repair of the launch button

If the electric coser does not show signs of life, then perhaps there was a break in the electric cable inside the hull handle, or the button for turning on the electric motor is faulty.

In order to diagnose electricians, you need to disassemble the electrical appliance handle. The work is performed in the following sequence:

When access to the inner part of the electric ships is provided, using the multimeter, measurements of the resistance button for turning on the electrimmer are made. If there is no resistance after pressing, then this

The detail is subject to mandatory replacement. It is also necessary to check the locations of the power cable with the internal electrician located in the handle

device. Contacts should be checked “for a cliff” using a multimeter. Often such a malfunction can be determined “by eye”. After detecting the contact of the contact, it is enough to solder the damaged place to restore the operation of the electrimmer.

In the absence of a multimeter, diagnostic work can be done with an indicator screwdriver. For this purpose, you should include a fork in an electrical network and using this diagnostic tool

Find the “phase wire” and thus check the presence of electric current to the power button and after. If the phase current is detected in another electric circuit, then it is enough to install an electric fork on the contrary in the outlet so that the correct diagnosis can be carried out

trimmer malfunctions for grass. The second diagnostic option should be done with great care, t. to. There is a danger of electric shock while checking the integrity of the wiring.

Checking the electric motor

If the button for turning on the device and the sections of the internal wiring turn out to be intact, then you should proceed to check the electric engine. For this purpose, it is necessary to remove the cover cover, having previously unscrewed a few screws with a screwdriver.

The first thing to do after access to the electric engine is to check the operability of the brush unit. If the brushes are worn out over the maximum permissible value, then the electric motor can completely stop or work unstable. In the case when the brushes and the collector are in perfect order, you should proceed with the “call” the engine winding. In order to exclude the likelihood of a breakdown in both contours, one should alternate

Checking the stator and engine rotor. To perform this operation, it is necessary:

  • Remove the engine from the electric ships.
  • Turn on the multimeter in the resistance measurement mode and check all the collector plates for the break. When checking, there should also be no significant deviations in the testimony of the diagnostic device.
  • Check for a breakdown of the rotor winding per mass. For this purpose, you should connect one multimeter probe to the “mass” of the rotor, and the other to any collector plate. The multimeter should be installed in the resistance measurement mode of more than 1 MOM. The resistance of the working engine between the winding and the “mass” should be very large.
  • Measure the stator winding resistance indicator. If the resistance is absent, then in this case its malfunction can be stated in this case.
  • If the stator wiring is in perfect order, then it is checked by a possible breakdown on the case, in the same way as in the diagnosis of the stator.

When checking in this way, it is possible to establish the cause of the malfunction of the electric motor in 90% of cases. Carry out a check for an interval circuit, which can only manifest itself in the process of engine operation, in this way it will not work, but you can diagnose such a malfunction

According to indirect signs, which are manifested in reducing the power of the electric motor and overheating. If the electric motor is equipped with a thermorele, then such an electric cos, with an inter.flip circuit, will work for a short time, after which the trimmer will automatically turn off the grass. In some cases, the thermorelele can cause a malfunction of the trimmer electric motor for the grass, therefore, in the complex of verification

events should be included “calling” the thermallane using a multimeter or tester.

It is very simple to do this: in good condition, an electric current passes an electric current in a cold engine, in

The electrical circuit will be opened faulty.

The problems of performance of the electrocos associated with the cliff of wires are easily eliminated by swinging contacts, but if the motor “burned out”, you will need to perform a complex rewind process that can

perform only a qualified specialist. In many cases, it is much easier and cheaper to purchase a new engine and install it in the place of burned. This work can be done independently

If the electrician of the trimmer for the grass is in good condition, then you should pay attention to other types of malfunctions that can manifest during operation of the electrocos.

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:

  • 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.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

DIY lawnies repair: analysis of malfunctions and methods for their independent elimination

Repair of the lawn mower on their own: analysis of malfunctions and methods of their independent elimination of benzos.

In the 2nd case is recommended Connect another device to the mains. Electronic devices of course do not work when the fuse is damaged in the fork. To carry out repairs, you will need to disassemble the fork. For this purpose, you use a screwdriver and a tester.

Motor problems appear when overheating of the lawn mower:

In the beginning it is recommended to wait a couple of minutes so that the motor cools. In the 2nd case, it will be necessary to remove the stuck object. The effectiveness of the cooling system is located depending on the state of the air filter. Dirty device poorly passes the air, which promotes the device to turn off the apparatus. Specialists recommend cleaning and changing the filter once every couple of months (with the unchanging operation of the lawn mower). With a breakdown of the electronic engine, a corresponding smell and noise occur. In such circumstances, you will need to change the drive.

Does not mow grass

Fishing cutting is required

Too long fishing line for a trimmer cannot accelerate to the desired speed and therefore does not cut the grass well. For most, the electric cos Fine for a trimmer is cut to the desired length, as soon as it reaches a small blade installed on the edge of the safety shield.

If possible, with the help of long.ruble, remove the blown or rusted blade. In some models, interchangeable broken canvases for knife cuts with retractable blades can be inserted into the blade holder.Check by user management.

elektokos, does, look, video, engine, jammed

If there are no interchangeable blades for your electric ships (you may have to purchase a new shield), then the only way out. Cut the fishing line for a trimmer manually (see. below).

The winding of a new fishing line or a change of coil is required

If you need to wind a fishing line for a trimmer to an existing coil, then do it slowly, place a fishing line for a trimmer carefully and evenly. A poorly wiped coil can be jammed, and the fishing line for the trimmer will not be unwound from the coil.

It doesn’t work at all

No power supply

If other devices in the same circuit stopped working, check the shield: is there a burned fuse or a trained assault rifle or RCD.

Elektokos is not included in the outlet

Make sure that the electrocos is included in the outlet and there is electricity in the outlet.

The fork fuse has burned down

Replace the fuse in the fork. If the fuse burns out again when the electric coser is turned on, check it in the service workshop.

Incorrect connection of the fork

If possible, disassemble the fork and check the correctness of its connection.

Cliff in the cord

If the tool does not turn on or works with interruptions, then perhaps there is a cliff in the cord. If the power cord is connected to the screw (or simple clamping) contacts, check the cord for the cliff and, if necessary, replace it. Double insulation electrocos are connected by a two.core cord.

For some, you can buy a cord already equipped with a fork and connecting tips

Thermal protection worked

Thermos available to some, thermal protection may work if the electric motor begins to overheat. Cleam the aircraft ventilation grilles with a brush and let the engine cool so that the thermal protection is automatically dropped.

Faulty switch

You can probably check and replace the switch in the service workshop, but first clarify the cost of the repair.

Faulty electric motor

Wear or sticking of brushes can interfere with the operation of the electric motor. Replace yourself or contact the service center.

The battery is discharged

If the electric coser does not turn on, try to charge its battery.

Do not allow the battery to be discharged completely, because in some cases this can lead to its complete failure. Recharge the batteries as soon as the speed of work begins to significantly decrease.
