DISHACTING AND DIY APPLICAL RIGHT. Replacing fishing line in other types of coils

Repair of electric and gasoline lawn mowers with your own hands

Repair of lawn mowers of both gasoline and electric may need at the most unexpected moment. We will talk about the main breakdowns of homemade and proprietary equipment, tell you what to pay attention to, and by what signs you can recognize the malfunction.

Lawn mower. A wonderful alternative to a manual spit that facilitates and accelerates the mowing of grass in a wide variety of places, including those where an ordinary braid for grass simply does not turn around. But for comfort and convenience there is a complex modern mechanism that requires tireless attention and regular service.

Regardless of the manufacturer, all units have a similar design. Therefore, the repair of the Viking lawn mower with your own hands is carried out similarly to the repair of other brands: Husqvarna, Shtil, Bosch, Garden, Oleo-Mac. A home.made lawn mower will not be exceptions, but elimination of breakdowns requires elementary knowledge. Consider the most typical reasons for the engine failure, and repair the lawn mower with your own hands in the field.

Repair of the mechanical part for all types of lawn mowers

Regardless of the type of engine, the mechanical part of the braid braid includes knives, the ejection or accumulation device of mowed grass and the transmission mechanism. Most often, knives come out or end the fishing line for a trimmer.

Cleaning the mechanical part of the Bosh lawn mower

Damage or bending of knives is visible to the naked eye. Depending on the material and the degree of damage, the knives are replaced or restored by simple bending into the original state. With severe wear, the cutting part can be submitted. DIY trimmer’s lawmaker, made with your own hands, can fail for many reasons. Most often, this is an excess of the maximum permissible load for torque and the engine, since a knife is used instead of a fishing line.

When examining, check the condition of the air duct for the supply of grass to the container and, if necessary, clean it. complex mechanical breakdowns require a complex tool, special equipment, professional skills and elimination of such malfunctions is better to entrust professionals.

Additional parameters and functions

The list of not the most significant, but also winging attention of the parameters of the lawn mower includes:

  • The mulching function, which allows you to grind the cut grass and evenly distribute it over the area for the soil fertilizer;
  • The method of spreading grass in the absence of fishing for grass. In most models, it is rear, for work on the side of the road or the trail is more suitable;
  • Building material. The plastic makes the lawn mower easier and more maneuverable, but metal equipment will last longer and is equipped with a larger engine;
  • The ability to fold the handles is a convenient option for storing or transporting the lawn mower;
  • Smooth move. In budget versions, it is equipped with plugs of plastic or bronze, in expensive and high.quality. With bearings;
  • Protection against accidental inclusion and overheating of the electric motor;
  • The starting system. This can be a manual mode that reduces the cost of equipment, but a good device is equipped with Self Starter, which launches the engine with one click of the button.

For all lawn mowers, except for the version with an air cushion, important characteristics of the wheels. Width, quantity, diameter. The most common and convenient models. Four-wheeled, but you can find both two- and three-wheeled. The size of the wheels affects the ability to intersect. The wider and higher, the easier the mower moves on the uneven surface.

Lawn mowers, both gasoline and electric, may need repairs at the most unexpected moment. We will talk about the main breakdowns of household and proprietary equipment, tell you what to look for and what signs can be used to identify a malfunction.

Juniper (lat. Juniperus)

It grows poorly in the shade, acquires a “loose” crown, losing its decorative look. Do not raise the root neck above the ground, but do not deepen. With close groundwater occurrence, drainage of small gravel 10-20 cm thick is required.

Lawn mower. An excellent alternative to a manual spit, which allows you to mow grass easier and faster in various places, including in those where an ordinary braid for grass simply does not rotate. But for comfort and convenience there is a complex modern mechanism that requires constant attention and regular maintenance.

Regardless of the manufacturer, all devices have similar design. Therefore, the repair of a homemade Viking mowing is similar to the repair of other brands: Husqvarna, Calm, Bosch, Gardena, Oleo-Mac. Home.made lawn mower will not be an exception, but the elimination of damage requires basic knowledge. Consider the most common reasons for the failure of the engine and make your own repair of the lawn mower on the spot.

Dismantling engines of household power tools

First you need to disassemble the case of the tool itself (drill, peorater). All self.tapping screws are displayed from it. If their length is not the same, you need to remember their location. The case is neatly disconnected into halves, then remove the brushes from the nests. Raising the entire structure in the case, remove the stator from the anchor. Then the anchor is removed along with the bearings.

The electric motor of the corner grinder is also disassembled.

Be sure to read the article “How to choose the right power tool?””

The assembly is carried out in the reverse order, if necessary, brushes are replaced by new.

Repair of gas mowers

Two.stroke gasoline internal combustion engines are installed in the units. Repair of gasoline lawn mowers begins with clarifying the cause of the malfunction:

  • If the car does not always start, but the gas operation at gas pressure is normal, then in the carburetor mode the idle regulator is lost or incorrect fuel is used. The proportions of oil and gasoline are taken in accordance with the recommendations of the manufacturer. If after this work does not improve, the mowing carburetor will be repaired.
  • If unstable operation is observed in any mode and the engine does not work properly, this means that the air filter is clogged and the fuel pipe is clogged. The first elements are washed or vary depending on the size of the malfunction. Currents are blown by the stream of a compressed atmosphere, regulate the degree of needle pressure. You can not stretch the existing spring, because the effort on the needle will increase, and the engine will work worse.
  • If the engine starts effectively, but stops when the load is “hot”, the cause is poor air consumption. Remove the purge filter.
  • If the mower does not start, despite the organized fuel supply and its sufficient amount in the tank, the reason lies in the non.working ignition coil. It is replaced by a new detail after simple manipulations. The presence of a carbon felted on the spark plug is visually visible, an effective correction is the replacement of the element. A test candle should radiate a flash that is clearly visible to the naked eye in daylight.

The appearance of the spark plugs determines the damage to the system and determines the need to repair the engine of the lawn mower:

Fuel problems lead to engine malfunction. During the usual work, check the amount of fuel mixture in the tank, oil level and its condition.

Clean the carburetor yourself without resorting to the services of masters.

The unit is disassembled and washed with a technical tool prematurely blown by air. Before repeated installation, the carburetor is regulated and regulated. The contamination of the fuel hose can be eliminated by cleaning the cabin with a needle or replacing the heating filter. Sometimes the malfunction is caused by a cliff of the starter cord. This is connected or disassembling the starter to replace the element.

Gasoline engines work uninterruptedly on platforms with a slope of not more than 15 °, sometimes they overcome short falls up to 30 °. If the engine is on steep slopes, then malfunctions may occur, it is necessary to work in acceptable conditions. To improve the launch, the throttle lever, which stands on many models, is moved to the maximum position.

The gasoline engine does not work well when the piston group is worn out or the piston is burned out. To detect a breakdown, disassemble the engine and install good parts. Replace the elements in the case of a locked crankshaft with cracks in the engine or carburetor body.

The engine slows down when the exhaust duct is clogged up the stream. The lock is corrected by moving the piston to the upper position with subsequent mechanical cleaning of soot using a thin wooden rod.

The process of diagnosis and restoration of the cutting part

To understand why the lawn mower is unevenly mowing the grass, it works longer and consumes more fuel, you need to diagnose cutting parts. In most cases, it is possible to repair the lawn mower with your own hands.

  • 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.

Before work, dense gloves are necessarily put on, because you will have to remove sharp cutting elements.

Stage Description
Cleaning From the knife you need to completely remove the grass and other pollution
Removing fasteners Unscrew the bolt with a wrench (most often it costs 19 fasteners)
Installation of a knife Put a new knife in the correct position and tighten the key, following the instructions
Examination They twist the nozzle with their hand and check the uniformity of its rotation: the distance to the decree remains the same
Establish a working position The lawn mower is removed from the supports and collected

If during the repair of an electric lawn mower with your own hands it is not possible to unscrew the bolt, you need to hit it several times with a hammer, applying small strength.

Important! If you still fail to remove the bolt, it can be watered with kerosene or brake liquid. The main thing is not to make too much effort so as not to disrupt the part

The main thing is not to make too much effort so as not to disrupt the part.

Replacing fishing line in trimmer

If the device has a fishing line for a trimmer, then it looks like a reel with wound thread. Replacing it is easier than the rotor, since the instruction is in every new material.

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;
  • 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.

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.

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.

Electric motor for the lawn mower

The lawn mower is a type of garden equipment designed to mow grass in large areas. There are two types of lawnmands. Depending on whether there is an engine on this unit or not, they are divided into mechanical and motor. In turn, motor law mushrooms are divided into three types: battery, with an electric engine (electric and self.propelled electric gas mowers) and with a gasoline engine.

right, replacing, fishing, line

In electric lawns, the electric motor has a power of 0.8 to 2 kW. Such lawnmands are used mainly for processing areas, the dimensions of which do not exceed 8 acres. They are quite simple in operation and maintenance, have small size and weight. Thanks to this, they are easy to move and store. In addition, during operation, the electric lawners Stiga, Gardena and Champion do not emit much noise.

However, along with many advantages, this unit has one drawback. this is a link to the network. During the operation of this lawn mower, it is necessary to ensure that the network cable does not fall under its cutting system

That is why, when buying a lawn mower with an electric motor, you should pay attention to that its network cable is bright

When working with an electric lawnical mower, certain precautions should be observed. First, to mow grass with this unit only in rubber shoes

Secondly, in no case can you use an electric lawn mower in raw and rainy weather.

The electric motor in the lawn mower is a rather complicated device. He requires neat treatment and a certain care. Before starting to work with an electric lawnical mower, it is necessary to check the processed area for the presence of stones and other extraneous items, which can harm both the gas mowing mechanism and the employee himself. If possible, all foreign objects from the site should be removed.

Can you cast this hard without a bird’s nest!?

Speaking about the power of the electric motor of the lawn mower, it should be highlighted that the larger it is, the greater the width of the capture. In addition, it should be noted that if more than 30 centimeters have grown in the processed area, the electric lawn mower will not be able to cope with it, since its motor is not designed to work in such a volume. Therefore, for starters, it will be necessary to process the plot of a scythe or trimmer.

It should also be highlighted that when operating an electric lawn mower in the network to which it is connected, voltage drops may occur. Because of this, the engine of this unit may quickly fail. Therefore, when buying a lawn mower with an electric motor, you should also purchase a stabilizer or even purchase a gasoline lawn. For example, Husqvarna lawn mower.

During a long operation of an electric lawn mower, its engine can overheat. Therefore, every 15-20 minutes of work, this unit must be disconnected and let it cool and relax at least 5 minutes. Otherwise, a spontaneous shutdown of the engine may occur, t. e. The protective mechanism of the lawn mower will work, which will indicate that the engine is clearly overloaded.

Repair of the mechanical part of the lawn mower

Distinguish between mechanical and electrical causes of the failure of the device. Mechanical include:

  • Breakdown and bending of a knife. This defect can be seen even with the naked eye. In this case, the grass is mowed unevenly, and the lawn mower can simply stop sharply. To repair the mower, you just need to bend to the original position. If one of the parts is completely broken off, then you will need to disassemble the device and replace the cutting part. If you lose sharpness, you need to sharpen with a file or an abrasive tape.
  • Weakening of bolt fasteners. The appearance of a whistle, as well as strong vibration and rattling, indicates a crafted compound. To eliminate this problem, you need to turn off the device out of the outlet, using a special key tightly tighten all the bolts and nuts.
  • The drive belt for the lawn mower stretched or broke. You need to spin the fasteners a little, and then move the pulley and remove the failed part. The new belt for the lawn mower should first be installed on a small, and then a large pulley, after which the gear returns to its original position. It will be necessary to check the tension of the belt, the deflection of which should be less than 4 mm.
  • The frequent problem of the drive braid is the stretching of the cable. In this case, you need to carefully adjust it.
  • Zaror air duct. The braid can stall if the grass clogs the compartment for the supply of grass to the container. You need to stop the device, clean it and turn it on again.

It often happens that the line for a trimmer for a lawmaker has broken or ended. For some, this problem is quite significant, and they are interested in more experienced people, how to wrap a fishing line for a trimmer for a lawn mower. The process is actually not complicated and will take no more than 15 minutes. The coil of a trimmer for grass is a plastic case, inside which there is a cassette and a hook for convenient winding of fishing line. To remove the coil with a fishing line, you need to twist the central screw clockwise, then disassemble the head with a screwdriver and remove the coil. Then you will need to measure the necessary length of the fishing line and, having doubled it, wind it on the coil, and take the ends against each other. At the end, you need to assemble the head in its original state. As you can see, it is not at all difficult to season the fishing line for the trimmer in the lawn mower.

Also, the operation of the lawn mower can be stopped due to a foreign object from getting inside. In this case, a strong whistle and rattling may appear. To solve this problem, it is quite easy to pull out an extraneous item from the device. Sometimes this leads to a breakdown of the impeller blades. In this case, there is a risk of overheating of the motor, so you need to urgently replace the broken part.

Important! It is better to entrust to repair lawn mowers using special tools and skills. Yourself with a difficult breakdown, you can break the unit finally

My own version of the lawn mower with your own hands.

All those who have money for a factory lawn mower please! This is for those who feel sorry for the money for the lawnical mower and for those who like to craft. Here is my version.

So. There is a yard, covered not with tiles, not a paveant, but in grass and summer it grows and becomes unsightly. Taking a trimmer for grass and squinting the grass, but I don’t know how to mow or something else, but not. On the Internet I saw a lawn mower with my own hands from the engine from the washing room. cheap and cheerful! For me the most. Having gathered this miracle from a scrap metal came to delight, everything works and mows evenly, this is the result that I wanted. And the main thing is not killed. Here is my first option, so to speak for a test.

right, replacing, fishing, line

The motor from the washing room, the pulmonary fiction on the pulley polypropylene put down and drilled the hole through the hole, wanted to put the bolt, but it also turned out tightly, there the groove is on the pulley and plastic and went there with a staggering. A knife made of a simple piece of iron 3-4 cm wide and in a diameter of 35 cm. Paul knife at a height of 4.5 cm. There is enough motor for normal grass, on a very thick grass it stops. But after the first time passed, the second time has never slowed down anywhere else. The motor heats up, after the passage of 70 m2, let the motor cool so that it does not burn out. Mowed once a week. With mowing, the grass breaks all and turns out to be like mulching, you don’t even have to remove. But there are no stones on the site, so everything is fine.And now it’s time to ennoble it all and make a normal mower, since all the wooden wheels were loose on the wooden. Having collected all the details on the metal-receiving- the motor button, the trigger button, the wheels from the stroller, the disk 47050 mm saw, the iron barrel cover and a strip of iron and from the available profile 2020 mm and a piece of the pipe diam. 16 mm built the following miracle.

He also put on the skip with a soldering iron heating the fitting polypropylene and put on the skip, drilling through the hole with a bolt, he staggered a bolt, as the disk as a flywheel twists be healthy. Saw a saw through a 50 mm spacer. There is almost no beating diameter, but the top-down turned out to be 7 mm, well, not critical, there is no turning. The height of the grass of the grass also left 4.5 cm. The passage has increased, well, the mass too-16-17 kg. Due to the circular saw, it works like a flywheel, even with a thick grass, the disk slows down but does not stop due to inertia. All 180 m2 went with this engine and did not hench much. you can go without a break.

The result is this, I am satisfied, since the money was spent, well, the maximum of 500 works without complaints and copes with the set tasks with a bang. Something is simply not real.

21.06.2017, having worked as a lawn mower, did not understand for some reason not so beautifully as an old mowing. As a result, I thought to try to make a knife like an old. I made a woodcock from a canvas. After mowing, the result pleased me, but it is not clear why the saw disk does not give such a result, it is not clear. As a result, now I use the knife as in the picture and the result is different, spins in a fraction of a second, but it stops on the big grass, since there is no inertia like on the disk.


All electric lawns are arranged the same. They have a platform for mounting a motor whose shaft is parallel to the ground. A knife (or two) is fixed on the shaft of the electrical device, with which weeds mush. To make the mowing high.quality, the speed of the cutting electrical tool should be high.

The platform itself for convenience is supplied with four wheels and a handle with the elements mounted on it that control the engine. It is designed to push the device forward and control an electric mower.

Wheel fastening can be stiff and be rotary. In the first case, you will have to raise two wheels in the corners. Rotary ones provide for the use of lower physical strength.

In addition, they “spoil” the lawn less. Therefore, if flowers are planted on the lawn, there are swings, arbors, etc.D., it is recommended to use rotary wheels. Electric lawns with such wheels are convenient for caring for areas under shrubs and trees.

The engine is closed by a case that simultaneously protects from injury by random objects of an operator working with an electric lawn mower. The material used for its manufacture is more often plastic and less often. metal. As you can see, the device of the electric municipal mower of the electric is quite simple.

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 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.

How to clean a carburetor?

Start by checking for open fire nearby. Do not repair the room. It threatens gas leakage.

Unscrew the screws with a flat screwdriver to remove the plastic cover of the air filter from the engine. Check the clogged filter, remove it using a vacuum cleaner or replace it with new (if the condition is unsatisfactory).

It is also necessary to remove the inner cover of the filter, which is located under the lid. This is easier to do with the help of a ring wrench, unscrewing the bolts. The air hose is attached to its inside, which should also be removed.

Finally we got to the carburetor of the device that can be disassembled. After disconnecting the fuel hose leading to it from the tank, t.E. Removal of the clamp, the hose returns, trying to remove it from the nozzle. Do the job carefully. After all, if there is fuel in the tank, it will definitely differ.

The carburetor is installed on the engine using two bolts, for unscrewing which the clutch head is required. When unscrewing the second bolt, try not to lower the carburetor so as not to damage the spring suspension.

The next step. Return the spring. The operation is more convenient to carry out on the side where it is attached to the motor. Now you can delete the cable responsible for the position of the lid, carefully turning the carburetor counterclockwise.

After removing the carburetor, unscrew the bolt with which the fuel chamber lid is attached.

Cleaning is carried out with a special liquid or WD-40 and a copper wire from which isolation is removed.

Finally, you can remove a plastic float located under the camera cover, which regulates the level of gasoline for which the pin is first removed.

The camera should be cleaned of plaque. The inside of the carburetor is abundantly moistened with WD-40 (or analogue), wiped dry. After repeating the operation, they clean the copper channels of the copper pipeline and blow them up, because their pollution is the main reason why the engine stops or does not start.

Read how to use an electric trimmer for grass

Having completed all the described steps, collect the carburetor in the reverse order.

After installing it in place, connecting the hose, air leaves the fuel chamber. This completes the repair.

After the manipulations described, the equipment will easily start and will work stably.

The reasons for the failures of gasoline engines

Gasoline (especially four.stroke) internal combustion engines are designed to operate in areas with a slope of not more than 15 degrees. Short.term 30 degree distortions are allowed. With large inclinations, the motor may stall. A part of the models of the braids has a gas lever: you need to set the ignition on the lawn mower to the maximum before work.

DIY internal combustion engine repair is considered a more difficult occupation than an electric motor. This is due to the greater complexity of its design. You need to know the device of two.stroke and four.stroke engines, their design features.

When starting repair work, you should check the course of the cable of the bracket (lever) of safety. You may need to adjust it.

What?! An easy WAY to spool your REEL?

Fuel mixture problems

The simplest causes of problems with the gasoline unit are the lack of fuel. Its availability is not difficult to check. You should also see the condition and level of oil in four.stroke engines models. If it is contaminated or not enough, then you need to pour a new liquid, draining the old before.

During the constant operation of the mowing, the carburetor is contaminated with fuel combustion products or due to the low quality of the filled gasoline. As a result, the engine speeds swim. You can clean the carburetor node yourself. To do this, it will need to be disassembled and washed with a special tool. You can try initially blowing with air to remove clogs.

It should be remembered that before installation in place, the carburetor adjustment must be adjusted. For the motor to work well, it needs to be correctly configured.

The fuel hose is also clogged with poor quality gasoline. When it does not act, the saloon is cleaned with a needle and replaced by the fuel filter. When the air filter is clogged, the engine power drops. In such cases, the filtration element needs to be cleaned or replaced.

Break of starter cord

Often, starting problems are caused by a break in the starter cord. In the simplest version, the repair of the starter is to connect the rope with the knot. In more difficult situations, you will need to disassemble the entire node and change the cord.

Falf in the spark plug

If the gasoline engine does not start at all or immediately stalls, you should check the spark plug. She must give out a spark, visible even in daylight. To do this, it is twisted and inspected. If there is no spark, then the part is replaced. By the appearance of the candle, you can diagnose a breakdown:

  • If it is dry, then this indicates the presence of a problem in the fuel supply system;
  • When the candle is wet, the malfunction causes the incorrect operation of the carburetor;
  • In the presence of black soot on the candle, it is cleaned or replaced by a new.

Other breakdowns

The gasoline engine works poorly with partial wear or burning of the piston. For the repair, you will need to disassemble the engine and put entire spare parts. Mechanical breakdowns can also occur, for example, jamming of the crankshaft or piston, the appearance of cracks in the carburetor or motor body. In such situations, you will need to install new details.

Serious repair of gasoline engines require professional knowledge and skills. If they are absent, it is better to contact a service center to specialists.

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.
