Electric lawn mower stopped working. Carter testing algorithm for tightness

DIY lawn. What malfunctions can be eliminated on your own.

Depending on the area of ​​the lawn and the growth of grass on it, the owners choose the optimal technique in characteristics. It is several types:

The average mower stands in the climatic conditions of St. Petersburg, or similar regions about four seasons. expensive or less operated garden assistants are able to withstand in the field of 5-6 seasons.

Also, the restoration of lawn mowers with your own hands will be required if the conditions of winter storage are inappropriate. For example, after use, there were no cleaning surfaces or there was no off.season preventive maintenance. As a result, various problems are manifested:

• frequent sharpening of the lamp of the lawn mower is required;
• just does not start a lawn mower;
• The motor starts up, but through a short gap the lawn mower stalls;
• malfunctions of the carburetor appear, which requires not only disassembly, but also cleaning with repair;
• Do.it.yourself renovation of the lawn mower is required with a significant reduction in power during operation.

You should not go to an expensive service center. Many problems can be solved with minimal costs and repairs on your own.

After each use of the tool, it is necessary to clean the cutting elements. Change the oil regularly and perform a minimum risk.

If the surface of the engine is hot, increase the cooling time and reduce the operating time, this will extend the life of the engine.

What grass can be mowed?

Due to the low power of the engine, electric lawn mowers poorly mows high and thick grass, the only exceptions are those models in the instructions for which the possibility of such use is indicated.

In addition, do not use electric lawns for mowing grass, among which shrubs grow, because their trunks and branches are much harder and stronger, so the load on the knife and engine increases sharply.

Is it possible to mow wet grass?

One of the widespread issues that bothers the owners of these devices is the possibility of mockery of the grass.

Therefore, electric lawn mowers do not have moisture protection. Wetting mowing of grass is not only ineffective, but also dangerous, because moisture on vegetation can get inside the device and lead to a short circuit.

In addition, this moisture, due to high electrical conductivity, can lead to electric shock, which can lead not only to a blow, but also to death. Therefore, electric lawn mowers cannot be used to mow moist and wet grass; it is ineffective and dangerous.

On the slopes

The main rule that must be observed when working on the slopes or other burrs in the region is that simply move the mitch down the slope, that is, perpendicular to the direction of changes in the height. Therefore, the optimal trajectory of work on the slopes is the snake, which is why it is undesirable to use the side discharges.

When using any lawn mower with the front wheels of the piano, carefully monitor the direction of their movement, since unlike four.wheeled devices with rigid fixation of the front axle, they are much more sensitive to inclination.

This is especially true for self.propelled devices that are usually controlled by a wrist, but on the slopes this attitude can lead to problems. In the end, if the lawn mower changes its trajectory, it can fall into a zone not intended for mowing, and touch the curb or other obstacle.

In uneven areas

Remember that any collision of a knife with the ground not only dulls it, but also poses a serious threat to the engine, therefore, before mowing grass, try to align all small hills in the area.

If the soil rises evenly and the knife does not capture the soil in any position of the car, mow it just like ordinary slopes.

After the service, the mowing

After the mowing, follow these steps:

• Let the engine start lever and wait for engine stop.
• Disconnect the extension cord from the outlet.
• Disconnect the mower from the extension cord.
• Lawn mowing broom on the outside.
• Remove and lower the collector if it is made of plastic, thoroughly clean the ventilation holes, if it is a fabric, then turn it inside and cut it off well to remove the rest of the grass. Some herbackers can be washed with running water.
• Use wooden, plastic or rubber spatula for cleaning the grass.
• Turn the lawn mowed and use a wooden, plastic or rubber spatula to clean the grass deck.
• Clean the wheel shafts and bearings, including plastic or metal bushings, from grass residues and make sure that the wheels are easily rotated.

Can it be washed with water?

After use, gasoline lawn mowers are washed with a stream of water to clean from sticky plant residues, but this method cannot be used for electrical devices, since they do not have water protection.

Therefore, never wash the lawn mower; Instead, use various brushes or blades made of soft materials to clean from the outside and inside the machine from lost vegetation.

How to disassemble?

At the end of the season, as well as to reduce the dimensions of the device during transportation, the lawn mower should be dismantled. For the vast majority of models, the disassembly is that they are disconnected from a handle fixed with lamb nuts or some high.speed clamps, although other installation methods are possible.

Having removed the handle, disconnect the lever with the corresponding wires. If people of different heights use a mower, then from time to time it is necessary to adjust the length of the handle so that it corresponds to the height of the operator. This operation is performed in different ways, depending on the arrangement of the handle, so it is necessary to strictly follow the recommendations set forth in the instructions for operating.

How to remove and install a knife?

A knife of any electric lawn mower is a consumable, so it must be periodically changed or imprisoned.

You will need to remove and install the knife the following tools:

To fix the knife, use a board or screwdriver (many holders of the lawn mower hold the knife with your hand, and then unscrew the bolt, turning it counterclockwise.

Unscrew the bolt, remove the old knife, then set the new one in place in the same position so that it coincides with the latches, and tighten the bolt. To tighten the bolt, fix the knife with a screwdriver or plate (often the owners of the lawn mower hold the knife with their hands because it does not require much effort).

How to sharpen a knife?

Manufacturers of all rotary lawn mowers recommend changing knives, as this increases their profit, forcing the owners of the mowers to regularly buy not too cheap spare parts. However, most owners of these devices will be able to sharpen the knives themselves, because their sharpening is practically no different from the sharpening of ordinary kitchen knives.

Sharpening can be done with:

Follow the following rules when sharpening:

• Support the factory angle of grinding;
• Delete the minimum amount of metal;
• Sharpen the blade to remove dents and shells;
• Remove the same amount of metal on both sides of the knife.

The lawn mower is buzzing but the knife does not spin

Repair of the lawn mower is carried out taking into account the mechanism of operation and the prerequisites for the breakdown of the unit. often the device fails 3-4 years after active operation.

Repair of lawn mowers is needed in subsequent cases:

The causes of the malfunction

The prerequisites for the failure of the lawn mower:

In the first case, you will need to change the case, handles, knives and wheels for lawn mowers. When blocking the knives, an mechanical stop of the unit occurs. Such a breakdown is associated with an attempt to mow hard or high grass. Repair of a mower consists in freeing the cylinder from stuck grass and scrolling it in the other direction.

When operating, a lawn mower with a blunt or crumpled knife, the grass is mowed uneven. With all this, the device can vibrate or brake sharply.

In order for the device to work properly, it is recommended to sharpen the knives with a ratfoll (angle of 30 °). In an unpleasant case, an abrasive tape is used. The gap should be between 2 blades, touching the strip. The device cuts off periodically (15 seconds). If the knives are sharp, then the strip is removed, the gap is regulated.

At the wrong position of the knives, the cylindrical lawn mower makes sharp and uncontrollable movements. Normally, the size of the gap between the cutting elements should be thinner than the sheet of paper. The motor is good at well, but the knife does not twist. But nothing helped, the motor is spinning, and the knife. In an unpleasant case, the gap is adjusted. The engine is buzzing but it is not clear how it works. But they say that they were allowed from it 2 kW. For earlier it is recommended to study the device annotation, pull the fork out of the outlet. With a cracked connection, a whistle occurs. The device vibrates and rattles. Under the repair of the lawn mower, it is planned to adjust the bolt joints.

If the belt breaks or stretched, then you need to change it. To do this, you will need to loosen the screws. Then the pulley moves, the belt is dismantled. The brand new detail is put on a small one, and then on a large pulley. The gear is fraught in its original position. The next step is to check the stretch of the new belt. The deflection should not exceed 4 mm.

A malfunction of electrical models

The prerequisites for a sudden disconnection of an electronic lawn mower are associated with a cliff of the cord or the absence of current. In the first case, it is recommended to check the cable for a cliff. To change the power cord, you will need to pull out the plug out of the outlet, open and dismantle the circuit lid.

Before unscrewing the clutch of the cable bar? You need to understand the diagram of its connection to the switch. To disconnect the cord, a hexagon is used (1 mm dialect). The electric motor is buzzing, but does not twist. But the knife does not spin. The lawn mower turns on. The clip is released, the conductors are dismantled. To check the cable for a cliff, multimeter is used. A new cord is installed as needed. With all this, a revolutionary sequence is observed.

In the second case, it is recommended to connect another device to the mains. Electric devices may not work when the fuse is damaged in the fork. To carry out repair work, you will need to disassemble the fork. For this, a screwdriver and a tester are used.

Motor malfunctions occur when overheating of the lawn mower:

In the first case, it is recommended to wait a few minutes so that the motor cools. In the second case, you need to remove the stuck object. The effectiveness of the cooling system depends on the state of the air filter. Dirty device poorly passes air, which helps to turn off the device. Experts advise cleaning and changing the filter once every 3 months (with constant operation of the lawn mower). With a breakdown of the electric motor, the corresponding smell and noise appear. In this case, you need to replace the drive.

Motor breakdown

The design of a gasoline lawn mower, unlike an electric counterpart, is more complicated. In some cases, the unit cannot be repaired. If the engine does not start or stop immediately, then it is recommended to check the ignition. This will need to be dismantled. Dry candle indicates problems in the feed system, and wet. on the carburetor. In such cases, repair work is carried out by professionals.

If there is a black fog on the candle, then it is replaced. In this case, the reason for the breakdown of the lawn mower is not taken into account (setting the carburetor, poor.quality fuel). The engine is buzzing but does not rotate. forum about radio. Often in gasoline models, the fuel hose clogs. If gasoline does not flow, then the saloon is cleaned with a needle, and the fuel filter is replaced by a new analogue.

If the lawn mower does not mow grass, then the knives are checked. If necessary, they are replaced with new cutting elements or Nat. In the second case, it is recommended to use protective glasses and thick gloves. You can drag the braid knives using special devices included in the set of the device.

If the knives are blocked by long grass, then it is recommended to turn off the lawn mower. A cylinder (in the other direction) to its free rotation scrolls with a wooden stick. If the lawn mower does not work as a result of a circuit breaker malfunction, then it is recommended to check it and replace it with a working analogue.

In the absence of voltage in the outlet, the shield is checked. Some devices are equipped with thermal protection. When such a system is triggered, ventilation grilles for pollution are checked. A soft brush is used to clean them.

Conclusion

Repair of mechanical braids is carried out when the cutting elements are blown up or damaged. In this case, experts recommend to independently dismantle removable knives. Evadal is used to sharpen them. If necessary, the battery is replaced in battery.

Carrying out repair of electric municipal mowers of electric ones: we set out all the nuances

Lugus maintenance and repair can be carried out with your own hands and at home. Naturally, the implementation of such works has its own characteristics. It is worth taking into account the need for appropriate knowledge, skills and tools.

Types of malfunctions of electric mowels

It is not difficult to repair the dull knives on their own, since they are removable and they can be sharpened with an ordinary emery, withstanding the sharpening angle of 30 degrees. In case of malfunctions of other details, t.e. hulls, wheels, handles, they will also need repair or replacement.

In the battery devices to this problem, the battery fails is added. It is more difficult to cope with the repair of a lawn mower equipped with a motor, t.e. gasoline and electrode.In the first case, the problem of overheating and overload is added to possible breakdowns, as well as malfunctions in the oil and fuel supply circuit. In electrical breakdown, it can also be caused by overheating or overload, since not all models are equipped with protection.

The process of diagnosis and restoration of the cutting part

• Drain the oil before removing the knives.
• Disable electrical devices from the network, and on gasoline units turn on the lock.
• Completely drain the fuel and remove the spark plug.
• Install the lawn mower on a support that promotes convenient repair.

Replacing fishing line in a lawn mower

In addition to knives on the lawn mower, a fishing line for a trimmer can be installed. Such a nozzle is a reel on which a nylon thread is wound. There are two varieties installed on mowers: there are two varieties:

The structure of the nozzle is simple: there are two departments in the coil, there is a partition between them, in which there is a notch. The thread is wound on these paths. For its withdrawal from the coil, special holes are provided.

In addition, the polyethylene thread varies in the form of its cross.section. This determines the field of use (purpose) of the material. According to the criteria for a fishing line for a trimmer, there may be various types:

• round, which is the most durable variety used to mow grass;
• figured, used in the spent of plants with soft stems;
• twisted, suitable only for thin grass.

There is a professional cord. But this variety is suitable for use not on all equipment models.

The nozzle itself is rarely damaged, only wears out and the nylon thread ends. To resume work, you need to re.wind a fishing line for a trimmer. It is worth buying a cutting thread suitable for the coil installed on the coil.

The order of work when replacing the fishing line in a coil with one osmus

To change the fishing line for a trimmer coil with one osik released, they come as follows:

• turn off the lawn mower, turning off the electric at the same time from the network;
• Remove the cutting nozzle, after stalling the shaft from turning, for example, using a screwdriver;
• disassemble the case, usually taking off its lid by pressing the latch;
• all the details are laid out carefully;
• cut off from two to four meters of fishing line with the diameter indicated in the instructions for the nozzle used;
• put a piece in half to divide it into two identical segments;
• in the ear, located inside the coil, they stretch one end of the cord;
• wind the thread counterclockwise (in a direction opposite to rotation of the nozzle during operation);
• leave a small end of the thread, which is exhibited through the hole, fixing first in a special groove so as not to spin;
• collect a coil;
• Install the nozzle on the lawn mower.

When a cutting nozzle with an automatic or semi.automatic supply of the cord is installed, there is a spring inside it. Therefore, analyzing the case, it is necessary to ensure that it does not fly away and does not get lost.

Replacing fishing line in other types of coils

To correctly wind the fishing line for a trimmer into a coil with two protruding ends of the cord, it is necessary to disassemble it. There are two recesses inside. In this case, the ends of the fishing line are laid out separately according to these grooves. Winding is also performed in the direction of the opposite rotation of the nozzle.

There are models of coils that have a different design. In such cases, it is often not required to disassemble the nozzle to insert the cord. The thread is inserted into a special through eye, located inside the coil. Fishing line winding is due to pressing the button. It is located directly on the body of the cutting nozzle and is intended so that with the wear of the cord it can be released new ends, without disassembling the coils.

Before wrap a fishing line for a trimmer, it can be pre.soaked for a short time in water. this will increase strength, as well as the elasticity of the inserted thread. Wrapping metal cables is prohibited. The cord must correspond to the diameter specified in the instructions.

The repair of lawn mowers should be proceeded only after preliminary familiarization with the instructions for their operation. There is the design of the model and the rules for its use. To minimize the probability of breakdowns, it is necessary to comply with the requirements for regular maintenance. You need to use only high-quality fuels and lubricants.

Before starting the mowing of the grass, it is recommended to inspect the pre.processed area for the presence of stones, stumps and other obstacles. This will help to avoid random clashes and unforeseen accidents. It should also be borne in mind that it is recommended to work with dry grass, because it clogs knives and other details of the mechanism slower.

Repair of benzocosyles

Two.stroke gasoline internal combustion engines are placed in the units. Repair of gasoline lawn mowers starts by searching for the cause of the malfunction:

• If the machine does not always start, but the work at gas pressure goes normally, then the adjustment of idle revolutions in the design of the carburetor has lost or inappropriate fuel is used. The proportions of oil and gasoline are taken in accordance with the recommendations of the manufacturer. If after that the work does not improve, then the carburetor of the lawn mower is repaired.
• If unstable functioning is noted in any modes and the motor starts poorly, then the air filter is clogged, the fuel nozzle is clogged. The first elements are washed or changed depending on the size of the malfunction. The nozzles are blown with a jet of a compressed atmosphere, configure the degree of needle pressing. You can’t stretch the existing spring, t. to. The force on the needle will increase and the engine will work worse.
• If the motor is effectively starting, but stalls when the load is supplied to the hot, then the reason is in poor air intake. To eliminate the filter.
• If the lawn mower is not started, despite the organized receipt of fuel and a sufficient amount in the tank, then the reason lies in the non.working ignition coil. It is changed to a new detail after simple manipulations. The presence of soot on the spark plug is visually visible, the effective correction is to replace the element. When checking, the candle should give out a flash, which is clearly visible with the naked eye in daylight.

By the type of candles, damage in the systems is determined and the need to repair the lawn mower engine is revealed:

• A dry candle indicates problems with the intake of fuel;
• Wet surface indicates incorrect operation of the carburetor system.

Fuel problems cause a refusal of the motor. When working, the amount of combustible mixture in the tank, the oil level and its condition are regularly checked.

The carburetor is cleaned independently, without resorting to the services of masters.

The node is disassembled and washed with a technical tool, pre.blown with air. Before the reverse installation, the carburetor is adjusted and set up. The clogging of the fuel hose is corrected by cleaning the saloon using a needle or a filter of heating is changed. Sometimes the work failure is caused by a rupture of the starter cord. It is connected by a knot or disassemble the starter to replace the element.

Gasoline engines work without problems at venues with a slope of not more than 15º, sometimes they overcome short drops to 30 °. If the engine stalls on steep slopes, then there may not be a malfunction, you need to work in permissible conditions. To improve the start, the gas lever that stands on many models is transferred to the maximum position.

The gasoline fuel engine does not work well with the wear of the piston group or the piston burning out. To identify a breakdown, disassemble the engine and install serviceable spare parts. Replace the elements in the case of a staging crankshaft, with cracks in the casing of a motor or carburetor.

The engine slows down when clogging the exhaust channel at the output. The blockage is corrected by transferring the piston to the upper position, followed by mechanical cleaning of soot with a wooden thin rod.

Electric lawn mower will not start or stall

Sooner or later, many are faced with the exit of the lawn mower. This happens, as a rule, after 3-4 years of active operation or after the device was stored in the winter in a non-heated room.

The lawn mower was out of order if:

Problems with the engine arise over time for all devices, regardless of whether a simple “Chinese” or an expensive “Japanese” stand on it. The moment is unpleasant, but you should not be upset, just as you do not need to rush to the service center. You can try to carry out repairs yourself.

The main problems with gasoline machines

Primary diagnosis is carried out from the stage of elimination of the most obvious breakdowns. When the motor does not start, it is worth monitoring the presence of fuel in the tank. If there are its remnants from last season, then it is worth replacing it. Low.quality gasoline after wintering is able to lose its characteristics, give an undesirable sediment or even stratifying at a fraction in density. In this form, he is not able to start the engine, but only clogs the system.

At the second stage, we find out why the spark does not appear. Its loss will not make it possible to ignite the fuel. Remove the cap from the candle and unscrew it from the planting nest by a special clip that came with a mower. Next, we throw the cap to the candle, bring it closer to the threaded part or the metal element of the motor, and at this time the partner pulls the starter.

With such manipulations, a blue powerful spark is required to appear in the working node. She will be able to notice her even in daylight. It is important to test this next to the unpainted metal part of the engine that can conduct current.

When there is no spark, you need to go for a new candle to the store. Do not return to the motor even with a weak or unstable spark. It is better to clean the working contacts from the haze on the head.

During operation, the occurrence of rattling in the design is possible. It at first does not affect the performance of the mechanism as a whole. However, it can lead to unbalancing and increased noise during operation. It is worth tightening the fasteners on the frame in a timely manner.

Tightening fasteners on the frame

An uneven slice of grass is evidence that you need to sharpen a lawn mowing knife. It’s not so difficult to get to them, but it is important to completely turn off the equipment from power. You can work on your own using tisses and files or on a solid sandpaper. It is important to ensure the cut angle uniform throughout the line 30 degrees. If there are excellent sections in the surface, then this is evidence of getting on a solid surface. Replacing them will cost quite expensive.

After turning on, a whistling sound appears. An unpleasant acoustic effect is associated with the penetration of foreign elements inside the design. They can block the video in the aerator. You can solve the problem with disconnecting a blocked roller and subsequent extraction of an extraneous subject.

When the lawn mower does not start

Depending on the area of ​​the lawn and the growth of grass on it, the owners choose the optimal technique in characteristics. It is several types:

Also, the restoration of lawn mowers with your own hands will be required if the conditions of winter storage are inappropriate. For example, after use, there were no cleaning surfaces or there was no off.season preventive maintenance. As a result, various problems are manifested:

• frequent sharpening of the lamp of the lawn mower is required;
• just does not start a lawn mower;
• The motor starts up, but through a short gap the lawn mower stalls;
• malfunctions of the carburetor appear, which requires not only disassembly, but also cleaning with repair;
• Do.it.yourself renovation of the lawn mower is required with a significant reduction in power during operation.

You should not go to an expensive service center. Many problems can be solved with minimal costs and repairs on your own.

After each use of the tool, it is necessary to clean the cutting elements. Change the oil regularly and perform a minimum risk.

Problems with the mechanical part

The mechanical system in lawn mowers with different drives consists of the following structural elements and nodes:

• knife (rotary or cylindrical type) or fishing line;
• transmission mechanism;
• grass collector and grass emission devices;
• wheels, handles and housings.

The failure of the cutting element

The most commonly damaged (for example, bend) or knives are blunt, the fishing line for the trimmer ends. This is easily detected with a simple visual inspection.

The fact that the cutting nozzles have become swept away is evidenced by uneven cutting of herbal stems when the lawn mowed.

Over time, knife fastening can weaken. Their balancing during rotation is disturbed, and vibration, whistle, rattling appear. If the knives are damaged, then during operation the mechanism will begin to perform unguided, sudden, sudden movements. To eliminate the malfunctions of this kind, the cutting elements are set to the right position, replaced with new ones or repaired. If possible, then the blades are pulled again.

Sounds and vibration during work

Uncharacteristic sounds, vibration, rattling appear during the operation of the unit, when the fasteners of its structural elements are weakened: body, engine. These phenomena are more often found in gasoline models, because their motor fluctuates more strongly than the electric motor. To eliminate these phenomena, check all the connections, pulling up the bolts if necessary. It happens that the whistle during the operation of the unit arises due to the entry into an outsider that blocks the video in the aerator. In this case, it is enough just to get it so that the sound stops.

Cutting nozzles do not rotate

Often, when mowing a high herbal cover or hard herbal, cutting nozzles cease to rotate due to grass clogging. This problem in most cases (if it has not led to more significant negative consequences) is easy to solve with your own hands, just picking out a stick with a stick.

Damage to constructive details

Damage to the wheels, handles and housing rarely happen. If they are significant, then they change these structural elements. Methods of repair, with its possibility, in each case, depend on the material of broken parts. they can be plastic, aluminum, steel.

Brand break

With prolonged operation, the mower wear out, stretches, and then the belt breaks off. At the same time, the device’s gasoline engine works, but the knives do not rotate. Self.propelled models can also break off the wheel drive belt: then they stop and do not go. Sometimes the clutch cable simply stretches and it needs to be adjusted.

How to identify the cause of the breakdown?

The repair must be started, guided by the principle of “from simple to complex”, t.e. It is recommended to start repairs by checking the availability of gasoline in the tank. If the gasoline apparatus has stopped after wintering, the fuel should be replaced.

After all, fuel, unfortunately, is not always worthy of quality. Therefore, during the prolonged inaction of the device, it can delay or form a precipitate. And the motors are sometimes very sensitive to fuel quality.

If there is no doubt as the latter, but the mitch does not start, it is necessary to check the spark by removing the wire with the cap from the candle, unscrewing it using the key in the kit.

Attach a candle to a clean metal surface (without paint), having previously thrown a cap on it, and asking someone to pull the starter.

If the spark of blue does not appear, the candle needs to be replaced.

If an unstable and weak spark appears, the candle will need to be cleaned with a file or sandpaper.

They change it in the event of a black carbon on the surface of the black carrier, regardless of whether it was formed due to the low quality of fuel or an incorrect carburetor.

Another problem, which is easy to eliminate, is a clogged fuel hose. Check this, disconnecting it: if the fuel does not flow, then the filter or saloon clogged. The filter will have to be replaced, the saloon can be cleaned with a needle.

Well, if after that the mitch earns. However, the reason for the problems in 90% of cases lies in another. the refusal of the carburetor, which will need repairs. You can deal with the repair by having enough experience. In its absence, the help of the service center will be required.

How to wash a gasoline lawn?

For washing, the lawn mower is delivered to the site, where not only there is access to water under slight pressure (0.5–3 bar), but also water is provided with the remains of doused grass. The hose is connected to the fitting on the deck and the water is served, after which it independently washes all the remnants of the grass and cleans the deck from the inside.

If the braid is not equipped with such a fitting, then it must be tilted to the side at an angle of 50-60 degrees and fixed in this position, after which the water stream is thoroughly cleaned.

After each mowing, it is necessary to wash not only the housing, but also the engine cooling ribs, for which they use the sprayer to avoid strong water pressure, because the water that comes under large pressure and one stream can penetrate the ignition system.

Therefore, it is better not to wash the engine with electronic ignition, but cleaned with a stream of air and sticks of soft plastic or wood.

After each washing or purging, it is necessary to carefully examine the exhaust pipe and the absorption of the air filter hole. If they have the remains of grass, then they are carefully removed.

Repair of malfunctions of gasoline mowing associated with the engine

Basin brakes use gasoline two.stroke internal combustion engines. Repair of a gasoline lawn mower begins with determining the type of malfunction.

The gasoline lawn mower is poorly started

It happens that a gasoline lawn mower is poorly started, but then it works normally. There may be one of the two reasons:

It is recommended to start eliminating a malfunction with fuel replacement. The fuel should correspond to a specific lawn mower by the composition. Gasoline and oil of recommended brands in the right proportions should be flooded in the tank.

If this did not help, remove and disassemble the carburetor and configure the idle system in accordance with the manufacturer’s instructions.

The engine of a gasoline lawn mower is hardly starting and unstable works at all modes

The most likely reasons:

Repair of the lawn mower in this case is as follows:

The gasoline engine starts, but does not hold the load

This happens when an air filter clogging. Repair of the lawn mower should consist in blowing or replacing the filter.

Repair of lawn mowers if the engine is not started

If the engine does not start with the correct supply of fuel, the problem is most likely to the ignition coil malfunction.

In the case of a simple malfunction, you can repair the lawn mower with your own hands. In difficult cases, it is better to contact professionals. Alfa-V company makes quick and high-quality repair of gasoline lawn mowers and other garden equipment.

Tools for diagnosing the electric motor

To identify problems in lawn mowers with a different type of drive and elimination of them, such devices and tools will be needed:

• indicator screwdriver;
• multimeter or tester with voltage indication;
• screwdrivers;
• keys of an abyss or hexagonal (depending on the fasteners used in the assembly of the equipment);
• pliers;
• Kusachki;
• knife;
• a hammer.

Of the materials, an insulating tape and the details identified during the verification may be needed.

The causes of breakdowns of lawn mowers are associated with the following factors:

• overheating or overload of the motor;
• bad contacts or ruptures in an electrical circuit (in electrical models);
• violation of the supply of fuel or oil (in gasoline units).

Therefore, you need to periodically, focusing on the recommendations set forth in the operational instruction, make stops during operation and constantly clean the equipment from herbal residues.

For internal combustion engines, the appropriate oil and the gasoline brand indicated in the passport should be used.

Problematic issues with a carburetor and fuel system

Before starting repairing the engine of the lawn mower, it is worth checking if the pistons lay down. To do this, it is necessary to dismantle the motor. We also remove the carburetor from the structure and conduct visual control for the availability of possible defects. Usually in disassembly you will need a special Torex screwdriver with nozzles.

Combined Torex reverse screwdriver with nozzles

We inspect the gaskets for the identification of ruptures or burning. If one is found, then you need to ensure the tightness of the structure, replacing them with new. The air damper may contain a layer of soot, which reduces the quality of the fuel mixture. You need to get rid of the cleaning of the carburetor by raining the node in the solvent or kerosene.

The causes of the malfunction

In the first case, you will need to replace the case, handles, knives and wheels for lawn mowers. When blocking the knives, an mechanical stop of the unit occurs. Such a breakdown is associated with an attempt to mow hard or high grass. The repair of the mowing is to free the cylinder from stuck grass and scrolling it in the other direction.

When operating, a lawn mower with a blown or damaged knife is mowed unevenly. In this case, the device can vibrate or stop abruptly.

For the device to work properly, it is recommended to sharpen the knives with a file (angle of 30 °). Otherwise, an abrasive tape is used. The gap should be between 2 blades, touching the strip. The device turns on periodically (15 seconds). If the knives are sharp, then the strip is removed, the gap is regulated.

In the wrong position of the knives, the cylindrical lawn mower makes sharp and uncontrollable movements. Normally, the gap between the cutting elements should be thinner than a sheet of paper. Otherwise, the gap is adjusted. It is recommended that you study the instructions of the device, remove the fork from the outlet. With a cracked connection, a whistle appears. The device vibrates and rattles. The repair of the lawn mower is meant adjustment of bolted joints.

If the belt is broken or stretched out, then it is necessary to replace it. This will need to weaken the screws. Then the pulley is shifted, the belt is dismantled. The new part is put on a small, and then on a large pulley. The gear returns to its original position. The next stage is to check the stretch of the new belt. The deflection should not exceed 4 mm.

A malfunction of electrical models

The reasons for the unexpected shutdown of an electric lawn mower are associated with a cliff of the cord or the absence of current. In the first case, it is recommended to check the cable for a cliff. To replace the power cord, you need to pull out the fork out of the outlet, open and dismantle the circuit lid.

Before unscrewing the squeezing of the cable? It is necessary to remember the diagram of its connection to the switch. To disconnect the cord, a hexagon is used (diameter 1 mm). The clip is released, the conductors are dismantled. To check the cable for a cliff, multimeter is used. If necessary, a new cord is installed. In this case, the reverse sequence is observed.

In the second case, it is recommended to connect another device to the mains. Electric devices may not work when the fuse is damaged in the fork. To carry out repair work, you will need to disassemble the fork. For this, a screwdriver and a tester are used.

Motor malfunctions occur when overheating of the lawn mower:

In the first case, it is recommended to wait a few minutes so that the motor cools. In the second case, you need to remove the stuck object. The effectiveness of the cooling system depends on the state of the air filter. Dirty device poorly passes air, which helps to turn off the device. Experts advise cleaning and changing the filter once every 3 months (with constant operation of the lawn mower). With a breakdown of the electric motor, the corresponding smell and noise appear. In this case, you need to replace the drive.

Motor breakdown

The design of a gasoline lawn mower, unlike an electric counterpart, is more complicated. In some cases, the unit cannot be repaired. If the engine does not start or stop immediately, then it is recommended to check the ignition. This will need to be dismantled. Dry candle indicates problems in the feed system, and wet. on the carburetor. In such cases, repair work is carried out by professionals.

If there is a black fog on the candle, then it is replaced. In this case, the reason for the breakdown of the lawn mower is not taken into account (setting the carburetor, poor.quality fuel). Often in gasoline models, the fuel hose clogs. If gasoline does not flow, then the saloon is cleaned with a needle, and the fuel filter is replaced by a new analogue.

If the lawn mower does not mow grass, then the knives are checked. If necessary, they are replaced with new cutting elements or Nat. In the second case, it is recommended to use protective glasses and thick gloves. You can drag the braid knives using special devices included in the set of the device.

If the knives are blocked by long grass, then it is recommended to turn off the lawn mower. A cylinder (in the other direction) to its free rotation scrolls with a wooden stick. If the lawn mower does not work as a result of the circuit breaker malfunction, then it is recommended to check it and replace it with a working analogue.

In the absence of voltage in the outlet, the shield is checked. Some devices are equipped with thermal protection. When such a system is triggered, ventilation grilles for pollution are checked. A soft brush is used to clean them.

Conclusion

Repair of mechanical braids is carried out when the cutting elements are blown up or damaged. In this case, experts recommend to independently dismantle removable knives. Evadal is used to sharpen them. If necessary, the battery is replaced in battery.

Before repairing the lawn mower, the type of motor is determined:

• Electric. engine feeds from current. The unit is disconnected as a result of overheating or overload. Some models do not provide protection against overheating. With mechanical damage to the engine, the help of professionals will be required.
• Gasoline. the device fails as a result of overheating, overload, breakdown of the oil and fuel supply chain. Basket lawn mowers, unlike electric models, are repaired longer.

To extend the service life of the lawn mower, it is recommended to comply with the rules of operation of the device.
