The electric lawn mower smokes when working. The engine does not gain momentum or does not hold them

The lawn mower does not start or stalls?

Many owners of gasoline lawn mowers sooner or later face technical problems of this technique. Most often, problems arise after three to four seasons of active operation of the lawn mower or after the equipment spends the winter in an unexplored garage. These problems are manifested as follows:

  • The lawn mower will not start
  • The lawn mower starts up, but soon stalls
  • The engine of the lawn mower is working with interruptions
  • The engine of the lawn mower does not work at full power

It doesn’t matter what engine is on your mower: dear Japanese Kawasaki or a simple Chinese Lifan, during the years of operation these problems are more likely to appear in all lawn mowers. However, do not be upset and rush to take your mower to the service center. In the vast majority of cases, the lawn mower can be easily repaired with your own hands. In this material, we will tell you step by step how to do it!

We identify the cause of the malfunction

To repair the lawn mower yourself, it is best to be guided by the principle of “from simple to complex”. First, check if there is enough gasoline in the tank. If the mower stopped starting after wintering, it is worth draining the old fuel and replace it with a new. Sometimes low.quality gasoline comes across, which can give a precipitate or even delay in the winter, and some gas mowers are very sensitive to fuel quality.

If there is confidence as gasoline, but the lawn mower does not show signs of life, the next thing you need to do is check the spark. To do this, remove the wire with a cap from the candle and twist it with a special candle key, which should go with the lawn mower. Then throw the cap on the candle, attach its threaded part to the metal part of the engine and ask someone to pull the starter. At this moment, a bright blue spark should appear, which is clearly noticeable even during the day. Keep in mind that you need to lean the candle against the clean metal surface of the engine, which is not covered with paint and which can be current.

A gasoline lawnie drive does not work

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

Repair of lawn mowers is necessary in the following cases:

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.

How the lawn mower arranges and works

If the engine works is not clear how it does not always start, it stalls under load. It’s time to make out.

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 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.

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.

Malfunctions of a gasoline lawn mower: the most common problems and their elimination

Like any motorized equipment, the lawn mower sometimes breaks and stops working or works incorrectly.

over, there is always a specific reason why the equipment works with interruptions, without eliminating its repair will only lead to a meaningless waste of finances and time.

Having sorted out a lawn mower and the reasons for the breakdown of certain mechanisms, in most cases it is possible to eliminate them on your own.

  • the most common malfunctions of gasoline lawn mowers;
  • the reasons for these malfunctions;
  • diagnostic methods;
  • Methods of repair and prevention.

The main causes of white smoke from the exhaust pipe of a gasoline engine

It is important to be able to distinguish harmless water evaporation and smoke itself. The steam is easy, without a trace, disappear in the air, then, as smoke turns into an oily blue fog behind the feed of the car

Consider the causes of white smoke from the exhaust pipe of the gasoline engine to correctly assess the costs of restoring the mechanisms and systems of auto.

Cooling liquid leakage

The most important node in the design of the machine, which always requires attention, drivers consider the cylinder block.

BC can be depressurized for several reasons:

  • The gasket burned out;
  • the cylinder head was deformed due to incorrectly twisted nuts;
  • A crack appeared in the cooling shirt of the block.

The last nuisance occurs according to the negligence of drivers, which add cold water to the hot engine or defrost the block with a large minus on the thermometer. Tosol enters the cylinders of the leaky block: white smoke comes from the muffler. Other symptoms appear:

  • The motor lubricant is cloudy, a bright yellow-brown emulsion appears in it, which is easy to notice in the flood neck;
  • Bubbles are formed in the expansion capacity;
  • The candles get drunk, smell of antifreeze, but sparkle like new ones: the working fluid perfectly launders the details;
  • power unit Troit.

The danger of a coolant in the cylinders is that ethylene glycol (component of antifreeze and antifreeze) is mixed with a motor lubricant, forms solid particles. The latter, acting, as an abrasive, destroy the details. And lubrication loses its qualities. Together, these circumstances derive the entire block out of the working condition.

Injector malfunction

They smoke both cars on injectors (Toyota, Renault, Peugeot), and technicians on carburetors (motorcycles, motoblocks, scooters).

The causes of white smoke from the silencer are as follows:

  • The supply of the fuel mixture or the operation of the gas distribution mechanism was violated, which leads to incomplete combustion of gasoline;
  • the components of the cylinder piston group have worn out;
  • There were problems with the cooling of the motor.

The last reason is the most likely for injector engines. Additionally, you will notice:

The smoke from the steam in injectors is characterized by high density, the smell of burnt oil, prolonged dispersion. A very disturbing signal when smoke does not disappear after heating the car.

The graduation tract, having stood the night, is covered with drops of moisture. Condensate is actively formed on metal in cool weather, when on a thermometer below 10 ° C. The appearance of moisture in the silencer is also facilitated by high humidity.

During the morning heating, the components of the exhaust system become hot, exhaust gases mix with drops of water, forming steam. As the condensate disappears, white smoke disappears.

Poor.quality gasoline with third.party impurities

Some drivers save on gasoline or diesel, fill the tank with cheap fuel at dubious gas stations. So you risk paying for water, which will freeze in winter and seal a small fuel filter net, plus an excess amount of sulfur. In combustion chambers, the substance turns into sulfur oxide, then mixing with water vapor, into sulfuric acid. The consequences for the engine will be catastrophic.

In the “left” gasoline, the octane number that causes destructive detonation is not controlled. And contains a toxic benzene and aromatic carbohydrates that increase soot, “eating” rubber and plastic. Alcohols and ethers create air traffic jams in fuel highways.

Oil burning out due to rings (smoke with a shade)

The remains of the motor oil from the rods of the valves and walls of the cylinders are removed oil scrap caps and rings. Worn rings lie, so excess lubricants burn out.

At the initial stage, the defect is noticeable during lifting uphill with a half.pressed gas pedal. A bluish smoke appears and quickly dissipates. In critical cases, the oil.removable rings of the smoke accompanying the car constantly, most of all when recruiting speed.

Moisture entering the cylinders

Under “moisture” should be understood as a cooling liquid. The reasons why white smoke comes from the exhaust pipe, look for cylinder heads or head defects. Most likely, these are cracks.

For accurate diagnosis, remove the lid from the expansion tank, start the engine. Now examine the liquid for oil spots and a specific exhaust smell. The discovered signs indicate microcracks or wear of the BC gasket.

Sisy smoke

If you find that there is blue smoke from the exhaust pipe, the reasons for this can be more than serious and it is unlikely to be able to cope on your own, since in this case the “root of evil” will be in the worn details.

The red tint indicates that the oil burns along with the fuel. In this regard, it is necessary to find out how it gets there. Most often, such “migration” occurs if:

  • Oil chopping caps worn out. The reason for this could be untimely oil replacement or the use of low.quality composition. In this case, an old, dirty liquid, with garbage and dirt played the role of an omentum. While you went in such oil, all the systems worked normally, but as soon as the liquid was replaced with a new one, it washed the system, and the oil.cut cap became a flood neck.
  • If you observe bluish smoke from the exhaust pipe, the causes may also lie in worn.out oil.cut rings that collect oil from the walls of the cylinders. If these elements are worn out, then the liquid will accumulate in the form of compression rings during the tact process and compression. In this case, it is recommended to check the compression.

Healthy! Smoke can be either transparent blue or rich white-blue. It all depends on the regime in which the engine works, the volume of oil and other factors. The bluish smoke does not dissipate and leaves obvious traces on the “test sheet”.

It is also worth noting that blue smoke from the exhaust pipe, the causes (this diesel engine or the gasoline engine has no particular difference) of which we examined, is also accompanied by a high level of oil and fuel consumption, the consumption of which increases by 0.5 liters for every 100 km.

And if we are talking about a motor with a turbocharged, it is quite possible that the problem is a spoiled turbocharger: bearings have worn out or the rotor was compacted. In the latter case, it is the most difficult to identify the malfunction, since the oil passes directly into the exhaust system, where it burns out.

In addition, the oil can penetrate the cylinders through the piston rings or the gaps between the valves and the guide bushings.

Also, if there is blue smoke from the exhaust pipe, the reasons may be covered in:

  • Worn elements of the cylinder-piston node (including the surface of the cylinders themselves).
  • Incorrect motor repair technology.
  • Deformation of the piston skirt. In this case, the motor will heat up hard.
  • Worn.out valve rods, as well as guide bushings.
  • Malfunctions of the ignition system.
  • Rust, which has accumulated in the cylinder or on the rings.

There have been cases and more exotic. For example, if a collector is installed in the car, which simultaneously acts as a laying of channels, it is likely that it has leaked. As a result, Tosol began to accumulate in the cylinder, passing through the intake manifold. In this case, you will notice that the pressure in the cooling system ceased to increase, and the fluid level has significantly decreased.

Healthy! If a brutal smoke appears for a short time or only in the process of warming up, then this indicates that the damage to the CPH is minimal, but still require close attention.

Car owners with an automatic gearbox with vacuum sensors may encounter a rupture of the regulator membrane, which will also lead to smoke blue

If the color of the steam is closer to black, then you should pay attention to other nodes

What should be done when white dense smoke is detected

When analyzing the cylinders, it is necessary to analyze the condition of the candles. The formation of scale on the candles indicates a water hit. After the examination of all cylinders and candles of the incurred in them, it is necessary to repair or replace the cylinders and candles. These measures are recommended to be performed using qualified masters at the nearest maintenance station.

Often, coolants of low quality when contact with the working elements of the engine cause enhanced corrosion of the nodes and parts of the power unit. Cheap varieties of antifreeze are able to literally corrode the internal parts of the engine when leaks occur. After such an impact, it is not possible to repair the spoiled details.

To make sure that the coolant penetrates the combustion chamber, it is necessary to remove the lid from the expansion tank. The pungent smell of burning, a decrease in the level of antifreeze in the tank, the floating oil film indicate the identification of this defect.

What is the white and blue exhaust gases talking about?

If the diesel engine smokes with gray smoke, motor oil burns out with the fuel in cylinders. Causes of oil entering the combustion chamber:

Falf of the turbocharger. Oil enters the intake tract through the seal of the turbine shaft;

  • Distribution of oil steam rings. Piston rings are necessary to remove the excess oil film from the walls of the cylinders. If the rings do not cope with their task, the oil remaining on the walls burns together with the fuel mixture;
  • wear of the valves. The seals are designed to seal the SBC cavity from the combustion chamber. Over time, due to a frequent temperature difference, rubber seals are blowing out and begin to let the oil into the combustion chamber. Most often, in this case, smoke with a blue shade appears after a downtime of the car and disappears a few minutes after the engine starts;
  • increased crankcase pressure. The reason is either in the wear of the cylinder piston group, or in the improper operation of the crankcase ventilation system. Excessive pressure in the crankcase space prevents the normal operation of oil.watering rings and drain from the turbine.

Diesel smokes white smoke in case of burning in the cylinders of antifreeze. Ways to get into the combustion chamber:

  • Contact zone of the GBC and cylinder block. The reason may be in corrosion of the cylinder head or gasket adjacent to the planes. The ingress of antifreeze into the cylinders can be caused by deformation of the HBC/BC.BC.BC reproductive planes (often occurs due to overheating of the engine), the installation of low.quality laying or non.compliance with the installation rules of the block head;
  • Club of the cylinder.

Why burn motors in trimmers and lawn mowers.

I decided to raise the topic and give recommendations on such a problem as the premature failure of electric lawns and trimmers.

If you do not take into account a banal marriage and a conspiracy of manufacturers, then one of the frequent causes of failure is a non.compliance with the power voltage. precisely, reduced voltage.

It is no secret that in the private sector, gardening, villages and villages, often the network voltage of the network is reduced. over, it happens that it is not just slightly reduced, but quite significantly (up to 200-80 volts, and sometimes below).

A low voltage leads to a decrease in the torque of electric motors and, as a result, to premature overheating and failure of the motor.

It is also very significant that these devices (lawn mowers and trimmers for grass) are always used with an extension cord. And the length of the extension cord can be tens of meters. If the cross.section of the wires in the extension cord does not correspond to the power consumption, then the voltage on the wires still “drops”. As a result, even if a voltage of 220 volts in the outlet, then at the other end of the extension cord it may turn out to be 10-15 below.

It should also be borne in mind that many manufacturers make the equipment designed for the European voltage standard (230 volts). By the way, in software, the voltage should also be 230, but it often does not reach 200 volts. These factors lead to the fact that the lawn mowers and trimmers for grass fail.

To avoid this and prevent the premature failure of the equipment, you need.

Be sure to use high.quality extension cords with a sufficient cross.section of the wire.

Briggs and Stratton Smoking Easy DIY Fix, Engine Is Not Blown. Riding Lawn Mower, Push Mower

Use voltage relay to turn off the lawn mower when the voltage drop. But in this case, normal work can be difficult or generally impossible, due to frequent operation of protection against low voltage. The voltage relay is advisable to use if the voltage “sags” rarely, but basically remains normal.

Use a voltage stabilizer of sufficient power. I recommend using a voltage stabilizer with a 1.5 multiple of power in power.

How electric lawn mowers are arranged

The general layout of electric lawn mowers is the same.

An electric motor is installed on the wheel chassis, directly or through the belt gear, a rotating cutting tool that cuts the grass at a certain height.

However, despite the general principle of work, all braids are divided into types of:

Type of chassis

Most lawn mowers are equipped with a four.wheeled chassis with a rigidly fixed axis of the front wheels, so for rotation, especially during the mowing of grass, it is necessary to press a little on the handle to tear the front wheels from the ground.

Indeed, during the turn, the direction of movement of the apparatus and the direction of rotation of the wheels do not coincide, which is why the latter resist the side movement, and the cooler the turn, the stronger they resist the movement.

Some models are equipped with front piano wheels, the axis of which does not have rigid fixation, so that the axis of their rotation clearly follows the trajectory of the lawn mowing, therefore, regardless of the steepness of the turn, they never move sideways.

Almost all three.wheeled lawn mowers are equipped with front piano wheels, so it is much easier to control them than four.wheeled. However, the most maneuverable are two.wheeled models, because regardless of the steepness of the rotation of their wheels never move sideways.

engine’s type

Asynchronous and synchronous engines are installed on electric lawnmands.

The former have somewhat smaller efficiency, but it is much easier to perceive high loads or overloads, the latter more effectively turn electrical energy into rotation of the shaft, but greatly increase the cost of the apparatus.

This is caused by both the highest cost of synchronous engines, and the need to protect them using belt transmission. The main difference between synchronous engines is the presence of contacts (collectors), therefore they are sometimes called collector engines, confusing with direct current motors.

Devices with a synchronous engine are well suited for the mowing of lawns and other territories planted with cultural vegetation, however, their use in areas overgrown with wild grass, especially tall and thick, is undesirable.

After all, such vegetation sharply increases the load on the engine windings and the brushes of collectors, as well as on the details of the belt transmission, all this leads to a rapid decrease in their resource. Asynchronous engines are deprived of this drawback, however, when working with them, it is necessary to use different methods of mowing well.groomed and high grass.

Type of cutting tools

The vast majority of the devices are equipped with a rotary cutting tool, that is, knives mounted on the engine shaft, which rotating, cut the grass and throw it through the side or rear window. During the rotation, such a knife is created by a vertically directed air flow that raises crushed grass and provides an even surface after mowing.

To some extent, the rotor cutting mechanisms can also be attributed to fox, which are installed on wheeled trimmers for the grass, only instead of a metal knife they cut the grass dispersed to huge speeds with a fishing line.

The main drawback of the knives of the rotary mechanisms is their vulnerability before solid obstacles, because rotating at high speed, they stock up enormous kinetic energy. Therefore, in a collision with an obstacle, not only defects of the cutting edge appear, but also the shape of the knife is often disturbed, due to which an imbalance appears, leading to strong vibration during engine operation.

electric, lawn, mower, smokes

Part of the lawn mower is equipped with a drum cutting mechanism, which is a hollow drum of steel plates, as well as a sharply.mounted knife operating on the principle of scissors.

The rotating drum captures the grass and leads it to the knife, which cuts vegetation, so such a mechanism is deprived of the main lack of rotary analogues. After all, the speed of rotation of the drum is much lower, which means that the energy accumulated in it is not enough to damage the plates, in addition, the knife does not contact obstacles at all, so defects do not appear on its cutting edge.

Method of ejection and processing of grass

The knife rotating at high speed not only cuts off the grass, but also gives it acceleration, so that the centrifugal force presses the cut vegetation to the deck, so it flies through the rear or side window, depending on the configuration and the operating mode of the mower.

If both holes are closed, then the cut grass passes between the ends of the knife and the walls of the deck, after which it falls down.

When working in this mode, falling fragments are quite large, comparable to those that fly through the windows provided for this.

If, together with a regular knife, set additional (mulching), then the size of the grass falling to the ground will be reduced several times, so this mode of operation is called mulching. All rotary braids can not only throw the grass back, but also collect it in the grass collector, this mode is in demand where for any reason you can not leave mowed vegetation on the site.

Drum mowers work a little differently. rotating, the drum accelerates the fragments of cut vegetation inside it, which are pressed to the tightly adjacent gas mowing housing. Therefore, at the time of passage through the output window, they fly out under the influence of centrifugal force.

All drum braids are equipped only with the rear emission, however, part of them includes a grass collector, so such models can be used not only for haircuts, but also to remove mowed grass from the site.

Way to travel

All electric lawns, regardless of the type of cutting mechanism, are divided into self.propelled and non.self.propelled. The former is equipped with a clutch and belt transmission, as well as a gearbox that lower the speed of rotation of the engine to the optimal level for wheels.

How to use electric lawn mowers correctly?

The use of these devices implies not only the mowing of grass, but also the maintenance carried out before and after the mowing.

In addition, for new devices, the correct assembly is also needed, because most of them are delivered in the form of individual nodes located in a common box.

Since the assembly methodology of each model is individual, we recommend that you carefully read the corresponding section of the instructions for the operation of the device, which is also often called the user manual.

Preparation for work

Preparation for work begin the external inspection of the device, paying special attention to the integrity of the insulation of the wires, including extension cords, in addition, do not forget to check all threaded joints. In addition, carefully inspect the mowing housing, if cracks or dents are found on it, then you can’t use such a device, first it must be disassembled and the condition of the internal parts and mechanisms is checked.

If everything is in order, then install the device on a flat surface, connect via extension cord to the outlet and turn on the engine. the mitch should work without knocking or vibration. After 10–20 seconds, if the smell of smoke does not appear, turn off the engine and disconnect the extension cords from the network.

then first eliminate their causes and only after that, having completed another check, proceed to the mowing of grass. In addition, do not forget to check the condition of the cutting edge of the knife, turning off the device from the outlet and waiting for the end of the rotation of the engine shaft.

If the knife is stupid or damaged, then replace it with a new one or sharpen it with subsequent balancing.

In drum mowers, check the condition of the drum plates and sharpening the knife, if the knife is stupid, then sharpen it, strictly following the operating instructions.

If you are planning to work with the grass collector, then check its condition and install it on the lawn mower to make sure that it adjacent.

Having discovered a loose fit of the traumatic collector, remove and eliminate the reason that is most often noticed during cleaning the grass.

Also check the ease of rotation of the wheels, if one or more of them rotate tightly, then check the condition of the bushings or bearings, if necessary, cleaning them from the grass.

If it is recommended to lubricate bushings or bearings in the operating instructions, then do this by finding the slightest resistance to rotation.

In addition, remove any solid items from the site, including:

The mowing of the lawn

Let’s move on to the question of how to mow grass properly. Start the mowing of the grass by unwinding the extension cord and laying it with large loops to exclude twisting when removing the mower from the outlet. Can be laid with a snake or in any other way, the main thing is that during the removal of the mowing he does not get confused and does not be in the way of moving the mower.

Then set the optimal section for this section, then first connect the cable to the outlet, then the lawn mower to the cable.

For ease of work, fix the cable using special mounts to exclude disconnecting the plug of the lawn mower from the cable socket.

On the vast majority of models, the engine is turned on using a button and lever, this is described in more detail in the operating instructions. Having turned on the motor, move the mower in the direction of the outlet, the non.self.propelled model smoothly push you in front of you due to your physical strength, activate the self.propelled drive using a special lever.

The speed of movement should be such that even a meeting with thick grass does not lead to a decrease in engine speed (they are controlled by ear). If the revolutions have fallen and the sound of the mower has changed, then stop moving forward and hand it a little, then continue moving forward, but already at a lower speed.

When working in the rear emission mode, including with an installed grass collector, a snake is the optimal trajectory of movement along the area of ​​the optimal trajectory.

To do this, first, on the edge of the site, remove to the maximum distance, then unfold the mower and shift to the width of the mowing sideways, then move the device towards the outlet.

If the turn is right, then the extension cord should be to the left of the mower, if left, then on the right. To reduce the likelihood of a wire fall under the knife, it can be thrown through the elbow of the corresponding arm. That is, when turning to the right to throw through the left elbow, and when turning left, through the right.

When working in the side emission mode, the cable should always be on the opposite side, and to reduce the likelihood of falling under the knife, it can also be thrown through the elbow.

Fixing the Smoking Electric Lawn Mower

When working with the grass collector, follow not only the indicator of its filling, but also the sound that the lawn mower produces. If the sound has changed, but there is no section with thicker grass, then the grass collector is full, so it is necessary to stop the engine and remove the mowed grass.

What clothes to use

The choice of clothing affects the safety and efficiency of mowing grass.

A dangling sleeve can hook and block the lever of the knife or wheel drive, and the probability of falling when working in shoes on slippery soles is very high.

Therefore, to work with a lawn mower, you need:

  • shirt with long fastening sleeves;
  • long pants made of dense fabric;
  • foot covering the leg on strong corrugated soles;
  • protective glasses or mask;
  • Hat or cap (on a hot sunny day).

How long can you use?

The optimal operating mode for each model is described in the operation manual for the lawn mower.

If this document is not available for some reason, then adhere to the Rules 15/10, that is, mow the grass for 15 minutes, then wait 10 minutes until the engine cools down.

Why is the lawn mower smoking

If your electric lawn mower smokes, carefully look at the signs of a malfunction. The cause of the malfunction can often be determined by the color of the clouds rising from the machine.

electric, lawn, mower, smokes

The lawn mower smokes white smoke

If the smoke from the car is white, the reason is most likely worn piston rings. Usually they form a seal between the walls of the cylinder and the piston. If the rings are damaged or excessively worn out, the oil will seep through them into the combustion chamber. As a result, the saw will begin to make a white smell, and its performance will deteriorate.

Another common reason why the lawn mower emits puffs of smoke is to get oil into the muffler. This usually happens when the machine turns onto the side. White smoke in this case is not a big problem. After the oil burns, it ceases to stand out on its own. However, this situation should not arise too often, as this will worsen the operation of the machine.

Warning. If the machine emits white smoke, it is worth checking the oil level in the system. If it leaks, using a scythe can be dangerous.

Oil leak in mowing muffler. usually after cleaning the device

The lawn mower smokes black smoke

Black smoke usually indicates the problem with the composition of the fuel. There are mainly two reasons for this:

  • Failed carburetor. This node is responsible for mixing fuel and air in the correct proportions. If this component is faulty, the mixture will be too rich. The fuel does not burn completely, and carbon accumulates in the system, which leads to a black exhaust.
  • Air filter problems. This component prevents dust, grass and other garbage in the engine. If you do not check the filter for a long time, it will inevitably block and stop passing the air. As a result, the fuel will be oversaturated, which will lead to the appearance of black smoke.

If the lawn mower is highlighted black smoke, this is a serious danger to the garden device. The car is unlikely to break the first time. However, before the mower can continue to be used, it is first necessary to eliminate the malfunction, otherwise it will eventually break.

The lawn mower smokes and stalls

If the garden machine not only selects smoke, but also stops after starting, the reason is usually in incorrect fuel. In particular, the malfunction is provoked:

Check if the device is smoking due to poor fuel quality is very simple. Enough the tank and fill it with good gasoline with an octane number recommended by the manufacturer. If after starting the engine the smoke disappears, the problem can be considered solved.

Sometimes the machine continues to smoke after replacing fuel. Then measure the oil level in the system. If it exceeds the Max mark on a special probe, excess should be pumped out.

If the mower is smoking, it is necessary not only to drain excess oil, but also replace the flowing oil seals

The lawn mower smokes and warms

Sometimes a mower emits smoke, but continues to work, although it overheats a lot. The malfunction is usually caused by the following:

In the case of importing and overheating of the car, the mitch should be turned off and maintenance should be carried out as soon as possible. Any garbage that has scored the working part should be removed and let the mitch cool to cool properly. If after repeated turning on, the machine still emits smoke and heats up, disassemble it and check the engine performance.

What to do if the lawn mower smokes

If the braid selects white smoke, turn off the car and conduct its inspection. This is carried out as follows:

  • Check the air and fuel filter and, if necessary, clean.
  • Replace the oil, the quality of the internal components of the machine largely depends on the quality of which largely depends.
  • If necessary, install new cylinders and piston rings instead of worn out.
  • Remove and disassemble the carburetor, clean it from dirt or completely replace it.
  • Check the condition of the spark plug and, if necessary, remove the carcass or install a new component.
  • Drain the fuel from the system and fill fresh gasoline of good quality.

Then the car is assembled and checked whether it continues to secrete smoke after maintenance.

Attention! If the problem cannot be solved with your own hands, it is better to take a gas station to the service center for engine repair and other complex repair work.

When operating mowers in mountainous areas with diluted air, it is better to use a special high.altitude corrector

Why do engines smoke

Power, which drives a two- or four-stroke engine of the lawn mower, comes from explosions in the combustion chamber. Like all combustion reactions, these explosions require oxygen, and when there is not enough air and incomplete combustion, fuel, which does not burn, turns into soot carbon deposits. They are either blown out of the final hole in the form of black smoke, or gather on the terminals of the spark plug, which protrudes into the combustion chamber. An engine that produces a lot of black smoke usually does not work at full power, and, in the end, carbon accumulates enough on the candle to prevent ignition and starting.

If your lawn mower produced black smoke and now does not start, you can usually start it again, cleaning or replacing the spark plug. Remove the spark plug lid, unscrew the candle with the end key and inspect the terminals., If they are covered with thick deposits, remove deposits with sandpaper or file, if you have a horse riding mowel or a mowing with a four.stroke engine, and you see wet oil deposits, you may be worn out by the lingel oil as a lingel oil. You can run the engine by cleaning or replacing the plug, but smoking will continue until you repair the seal.

Restore the air flow

Another reason for the lack of air in the combustion chamber. Dirty air filter. You must regularly clean this, but it’s easy to forget to do it, and when the filter is polluted, it passes the air. The filter is easily available, and the procedure for its removal and cleaning depends on your lawn mower. Many air filters are located on the side of the gas mowing engine and are enclosed in a plastic box held in place with a screw. Some filters are disposable and should be replaced, while others are washed with water with soap. Paper filters can sometimes be cleaned by blowing them with compressed air, and foam filters can be washed again. The muffler can also clog and limit the flow of air leaving the combustion chamber. Remove and clean the soot with a wire brush or replace it. In order to avoid burns, give the mower and muffler completely cool before shooting.

Small engine carburetors have two or three adjusting screws. one for adjusting the velocity velocity and the other one or two to adjust the air ratio of the air. When the engine produces black smoke, this may be due to the fact that the low-speed screw marked by the letter “l” on most cars is too open. Find adjusting screws that are often under an air filter, and turn a low.speed screw for 1/4. 1/2 revolution clockwise using a screwdriver to create a more liquid fuel mixture when you make this setting, you will probably notice that the engine is better because it burns fuel more efficiently.

A motor smokes at an electric lawn mower

Those who have land are very familiar with what struggle is weed.

Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid for grass.

But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.

The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.

Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.

But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.

The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.

AL-KO, the lawn mower of the company, has serious problems in work, namely: the engine stop without load and its strong overheating, was taken as an example. The motor stops, buzzes and start it again, only re.pressing the “Start” button helps. The button has to restart almost every 30 seconds, and with further work and more often.

Of course, you can work, but it is very annoying and gives the feeling that somewhere the problem is. Therefore, I wanted to figure out where?

After the mower was working within an hour, the engine temperature was measured. It was impossible to touch him with a finger. He directly radiated heat. If you continue to pay attention and continue to work on such a mower, an electric motor will inevitably fail.

It is necessary to determine the cause of the motor overheating. To do this, remove the top cover of the case, under which the engine is located and its power chains.

The lid is held on six screws with a hat under a cross screwdriver.

Unscrew these screws and remove the lid. upward.

Having removed it, you can see the impeller, the capacitor, two connectors and the engine itself.

At first glance, no special problems are invisible. The engine winding darkened slightly from the temperature, but so far it is not critical.

To more carefully inspect the capacitor, it is necessary to unscrew the mount and pull it out.

The capacitor of some external damage did not show.

To check it, you need to disconnect the capacitor and feed the engine for a short time. If he did not start and began to buzz, then the capacitor is intact, because the engine was launched with him. Disconnect the power and connect the container connector back to the engine circuit.

Next, try to twist the impeller. It is mounted on the axis of the rotor and rotates rather tight.

And the reason for such severe rotation is a mechanical brake, which for safety stops the engine rotation when the power is turned off.

It looks like a sleeve that moves freely from top to bottom, along the rotor axis.

Когда напряжение на двигатель не подано, эта втулка прижимается верхней частью о крышку, на которой приклеено две резиновые полосы. Thus, the knife is inhibited on the rotor shaft.

When feeding, the brake sleeve under the influence of the magnetic field is drawn to the center of the rotor and provides free move.

With a careful examination, this sleeve with the brake noticed that at the time of turning on the engine, the brake is retracted and gives the shaft free rotation, but after 2-3 seconds it is released again and begins to slow down the motor. This should not be. Hence the stop of the knife during operation and overheating of the engine.

To find out what is the reason for this work, you need to remove and disassemble the engine.

To do this, disconnect the connectors and put the device on the side to get to the clamping screws. Access to them closes a knife with mounting elements.

To remove it, first you need to unscrew the knife bolt (cm. Figure below).

Direction of rotation, like a regular bolt, and not with left thread. That is, unscrew it counterclockwise, and tighten the clock.

The head of the bolt is plastic, so using the key, it must be well planted so as not to “lick” the edge.

After extracting the bolt, the knife and its plastic disk are removed.

Under it is a height sleeve. With its help, you can slightly lower the knife.

Adjustment is carried out by the washers put under the sleeve (see. drawings below).

We remove everything, only the engine shaft and the hexagonal screws of its fasteners remain.

The key for these bolts has a distance between faces of 6 mm. Unscrew them counterclockwise. Removing the last screw, with one hand, hold the engine.

Why burn motors in trimmers and lawn mowers.

I decided to raise the topic and give recommendations on such a problem as the premature failure of electric lawns and trimmers.

If you do not take into account a banal marriage and a conspiracy of manufacturers, then one of the frequent causes of failure is a non.compliance with the power voltage. precisely, reduced voltage.

It is no secret that in the private sector, gardening, villages and villages, often the network voltage of the network is reduced. over, it happens that it is not just slightly reduced, but quite significantly (up to 200-80 volts, and sometimes below).

A low voltage leads to a decrease in the torque of electric motors and, as a result, to premature overheating and failure of the motor.

It is also very significant that these devices (lawn mowers and trimmers for grass) are always used with an extension cord. And the length of the extension cord can be tens of meters. If the cross.section of the wires in the extension cord does not correspond to the power consumption, then the voltage on the wires still “drops”. As a result, even if a voltage of 220 volts in the outlet, then at the other end of the extension cord it may turn out to be 10-15 below.

It should also be borne in mind that many manufacturers make the equipment designed for the European voltage standard (230 volts). By the way, in software, the voltage should also be 230, but it often does not reach 200 volts. These factors lead to the fact that the lawn mowers and trimmers for grass fail.

To avoid this and prevent the premature failure of the equipment, you need.

Be sure to use high.quality extension cords with a sufficient cross.section of the wire.

Use voltage relay to turn off the lawn mower when the voltage drop. But in this case, normal work can be difficult or generally impossible, due to frequent operation of protection against low voltage. The voltage relay is advisable to use if the voltage “sags” rarely, but basically remains normal.

Use a voltage stabilizer of sufficient power. I recommend using a voltage stabilizer with a 1.5 multiple of power in power.
