Self -propelled lawn mower is not going on the cause of DDE. The most common problems

Electric lawn mowers: device, operation, malfunctions

Owners of summer cottages and lovers of beautiful lawns, parks, sports grounds in the summer are constantly faced with the problem of their overgrowing grass. In order to quickly cope with this task, requiring significant labor and time, often use the lawnmands of various models. With their help, they support the optimal from aesthetic point of view the height of the grass cover. The assortment of equipment presented in the modern market allows you to choose the model suitable for the price and their operational characteristics without any problems. It will also not be difficult to choose spare parts for the lawn mower if necessary. But at the same time, certain nuances should be taken into account.

The task of all lawn mowers, in general, one is a lace haircut. Therefore, they are structurally similar to one another: each has a base, a cutting tool, a grass collector and an engine. The differences are hidden in details, which determine the design features of different braids.

Different cutting tools allow you to divide the braids into rotary and cylindrical.

Herbackers are tough, soft and half.timed.

Depending on the features of the engines and the supply system of the lawn mower are divided into manual, gasoline, network and battery.

Finally, the specifics of the base and the movement system allows you to divide the mowers into wheeled non-self-propelled, self-propelled, including full-fledged riders, air pillings, trimmers for grass and even miter-robots.

Now let’s talk about the features of the installation of braids of all types more details.

How the bases of different lawn mowers are arranged

Most lawnmands move on wheels. rubber or plastic.

Most often there are non.self.propelled wheeled devices that need to be pushed manually. This requires some effort, but the speed of mowing can be adjusted independently.

Self.propelled braids use engine power not only to rotate knives, but also to move the device forward. You just need to start the motor, and then the mower will go by herself. The operator can only follow the unit and set the direction of movement.

Ryders and garden tractors stand apart. This is already a full.fledged four.wheeled transport, the driver of which is driving in a normal seat, and does not weave behind a mowing behind, like Lander behind a plow. In addition, not only the lawn mower, but also other agricultural inventory can be connected to the power shaft of the power of the garden tractor. For a large lawn. the most, but in a modest courtyard with such a beast there is nothing to do.

The exact opposite of the riders is trimmers for the grass. They don’t have wheels at all, it’s just manual electro- or motorcycles. To handle the trimmer skillfully, you need a certain skill. But they cost relatively little, and in terms of universality they surpass any analogues. After all, a trimmer can be chopped by any weeds, cut the bushes and even trim the crowns of trees.

Exotic option. Air pillow lawn mowers. In such devices, the knives operate and as propellers that hold the devices in the air. Quite convenient and easy to maneuver, but very poorly common devices.

Finally, one cannot help but mention mit-robots. These are automatic devices that work similarly to robots and percussion. Modern robokoski are able to go around obstacles and generally take care of the lawn completely independently. Comfortable, but expensive and not yet perfect technology.

The design of the lawn mower

Now we will analyze the “anatomy” of this device. So, the gas mowing on a gasoline course is a four.wheeled device with a plastic or metal body in which the engine is enclosed. In simple and light models, he drives only cutting blades, so he has to roll a “four.wheeled friend” manually. However, it is not so difficult to move 12-15 kg from a place of 12-15 kg.

massive units are made by self.propelled. Their wheels rotate at the expense of the drive (chain or belt), and the user can only direct the lawn mower in the right direction. To make the work as comfortable as possible, manufacturers equip their models even with a speed switch (from 2.4 to 5 km/h).

As for the mowing process directly, almost all gasoline devices are rotary. The knives are installed in them parallel to the plane of the Earth, and during operation they create a strong air flow, which in turn draws out cut grass into the grass collector or throws it to the lawn, forward or to the side.

As we see, the device is quite simple. But, trying to raise the demand for their products, companies constantly add new options to them. It can be a special handle that reduces vibration, or a sensor that measures the height of the grass.

A separate mention is deserved by the mulching option that saves the summer resident from taking care of where to put mowed grass. To throw it away by waste, because this is a wonderful raw material for compost. But to rake the grass manually and attribute them to the composter tire. Why spend time and effort if the lawn mower can fertilize the soil on its own?

To transfer the unit to mulching mode, access to the grass collector is blocked. Small and crushed stems are poured onto the lawn, where they gradually decompose, turning into compost. But you should not get carried away in this way of fertilizer. Once a week enough. If you mulch the lawn more often, organic waste will accumulate on the lawn and damp, gradually turning it into a swamp. For the same reason, you can not work in mulching mode during protracted rains.

What to look for when choosing a gasoline lawn mower

The second parameter is the torque of the unit. The higher it is, the easier it will be to mow grass, especially thick and high. For the lawn on 1-6 acres, the torque should be about 6.1–9.83 h m. The maximum necessary for large land plots is 11.87 h m.

The body (deck) of the device is of great importance. It should be durable, since during the operation of the lawnmand of the blade, small pebbles and other hard garbage throw it on it. In the simplest, budget models of deck made of cheap thin plastic. Obviously, such a product will not last long. The metal case is much more durable, but it cannot be called impeccable. The paintwork, which is protected by the inner surface, abrasion over time, and under the influence of moisture (juice of grass), deck gradually rust.

The thermoplasty houses show themselves well. durable, reliable, not prone to chips. Multilayer plastic has established itself even better, which resembles Sandwich on the cut. As practice shows, it perfectly resists wear.

note! Starting from the end of July, many large produce and suppliers make significant discounts on the lawnmands, so the end of summer is considered the most profitable for buying garden equipment

Another important element of the lawn mower is a grass collector, the volume of which varies from 16 to 90 liters. It can be soft (durable waterproof bag), or hard (plastic box). The second option is preferable, since the product with smooth, solid walls is easy to empty and wash.

The method of launching matters. As mentioned above, in order to give the unit the action, you need to pull the starter cord. But there are models in which the engine is launched by pressing a button or turning the key. The electronic ignition system is powered by batteries. Lawn mowers with a hybrid system are also developed, where the launch can be carried out either using the/key button and using the cord. This can be very useful if one of the mechanisms fails.

The wider and larger the diameter of the wheel of the lawn mower, the easier it is to roll it around the site. Another plus of wide tires is that they do not leave traces on the lawn

When pressing gas

If the lawn mower stops when pressing the gas, then the reasons may be the following.

• The most common option is a fuss of adjusting the carburetor, which occurs with significant loads on the drive, after a prolonged inaction of the mechanism or when it is used in severe conditions.
• The clogging of the fuel valve, which eliminates it with the message, as a result of which gasoline according to the system begins to flow normally.
• The weakening and hanging of the cable in the carburetor. Also, a tensile of the fuel hose can occur up to its rupture, caused by the action of a significant load.
• Clogging of the saapun (check valve), as a result of which fuel does not enter the tank.

If the problem is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. Когда лопается шланг или растягивается трос — выполняют замену данных комплектующих.

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

How does it matter what kind of motorized equipment, the lawn mower bages from time to time and stops working or works incorrectly. At the same time, there is always a certain reason why the equipment works with interruptions, without eliminating its repair will only lead to a stupid embezzlement of money and time

In this case, there is always a certain cause why the technique works with interruptions, without eliminating its repair will only lead to a stupid embezzlement of money and time.

Having understood the device of the lawn mower and the reasons for the breakdown of certain devices, it can almost always be removed without the help of others.

• more frequent defects in gasoline lawn mowers;
• the reasons for these defects;
• diagnostic methods;
• repair and prevention methods.

It shakes strongly

Such a malfunction of a gasoline lawn mower appears in 2 cases:

In both cases, the prerequisite of the shaking is the lack of a knife balance, because when the knife is hit, at least there is not enough, but it is deformed, and with incorrect sharpening, the metal on both sides is removed unevenly.

As a result of this, a lever appears, the length or mass of the shoulders of which is at least insignificant, but differs. This leads to the fact that the shaft of the motor will always pull right behind the more languid or long.length shoulder of the lever, and thanks to its rotation, such an effort will also move in a circle.

To establish the cause, you need to prepare and install a gasoline lawn mower to the position for replacing the knife (these operations are carefully described in the operating annotations). Then the knife is painstakingly examined in search of damage, but if the external examination did not give anything, then it is removed and balanced.

With independent balancing, the knife is put on the rod and look at which sides will go down, for a more clear balancing, you can slightly twist the knife on this impromptu shaft.

Having determined the more languid side, it is gradually dragged by a raster with a manually or on a sharpener, checking the balance all the time, while the metal is removed only from the side of the blade, maintaining the initial angle of sharpening. In the same way, the knife is sharpened in home criteria, at first the tip of the blade, then balancing it.

On certain models of gasoline lawners, a shaking prerequisite can be a broken adapter between the motor shaft and a knife that protects the shaft from damage in a collision.

To diagnose such a malfunction, you need to install the device in a position for replacing a knife, then shake the knife in different directions and test it to scroll it.

If he even sways or turns a little, the adapter must be changed. because he completed his task, protect the shaft during a sharp stop of a knife, which can no longer firmly fix the knife. Its substitution is also described in the annotation of operation.

Poorly cut the grass

If after mowing the grass looks cloud, then cause there is always one. a dumb knife that needs to either be flooded or changed.

The incorrectly sharpened knife is rapidly stupid and loses balancing, which can lead not only to the emergence of vibration, and to the rejection of the motor bearings of the motor. If the knife can be sharpened, then do it because it is described in the last section.

The reasons for the weak.speed trimmer for grass

If users complain to the trimmer for grass, which does not gain momentum, this means that it works normally on idle, and when pressing gas does not develop the necessary power. This can happen as a result of a long downtime of the apparatus without activity. These problems are typical for gasoline devices, including the Husqvarna 128R, STIHL FS 38 and Hitachi different modifications.

Working with a trimmer, you need to monitor its behavior all the time. a drop in revolutions and unusual noises signal the malfunctions in the aggregate. Sometimes you give gas, and the trimmer for the grass swims. In such cases, the work should immediately be suspended, let the mechanism cool and start searching for possible problems. They can be of a different nature of both the technological plan and external factors related to the conditions and features of the operation of the device.

External factors

Several factors that are not related to its breakdown affect the reduction of revolutions:

• filter pollution due to the hit of particles of dirt and dust in it;
• use of poor.quality fuel;
• incorrectly prepared mixture (relevant for trimmers with two.stroke gasoline engines);
• pollution of the muffle of muffler particles of vegetation, soil elements and other objects.

In this case, in the second and third cases, the formation of a soil in the combustion chamber is formed, and the elements of the carburetor are clogged.

technical issues

The technical problems of the lawn mower mainly occur in the fuel and ignition system. You can cope with them yourself.

• Когда ручная косилка не заводится или глохнет, проблема может быть связана со свечой. The dark cargo speaks of poor carburetor adjustment and low gasoline quality.
• The reason for the incorrect operation of the trimmer for the grass may be clogged fuel hose. Filters are also often clogged.
• Another internal problem. the muffler is covered with soot. From this, the turnover of the grass for the grass falls strongly. Output. you need to clean the muffler.

Why does a self.propelled snowman not go?

The movement of the wheelbase is controlled by the friction disk. Rotating, he transfers effort from a tanker to wheels. With a sharp increase in loads, the friction wheel breaks and the wheel of the snowman stops spinning. The problem that occurs during the operation of rings is the emergence and development of foci of corrosion with increased humidity. When switching the gears due to rusty friction rings, a strong creak appears. It is impossible to restore the destructive friction rings, it is necessary to replace them.

Self.propelled snowman does not go back and forth if a traction belt or friction drive is poorly adjusted.

The lawn mower will not start

If the braid does not go, you need to check the drive belt. perhaps it is worn out and requires replacement.

Do.it.yourself pumping station repair

Do.it.yourself repairs of a pumping station will save you not only funds without the help of specialists, but also time (there is no need to look for where to repair the equipment and make an order to the service company, coordinate the master’s visit or go on your own, postpone current business). The recommendations of experts will help to navigate in the situation, determine the type of malfunction and eliminate the defect. Along with the tips, you can cope with the problem, but negligence in work can lead to more complex damage.

It is very important to determine the cause of the failure correctly, because otherwise we simply cannot eliminate it. If there are no extraneous sounds when trying to set up a chainsaw (knocking down, grinding, etc. D.), It often turns out that in fact there are no problems

For example, if you put the chainsaw and pull the fork for a long time, the engine simply pours and starts very much

D.), It often turns out that in fact there are no problems. For example, if you put the chainsaw and pull the fork for a long time, the engine simply pours and starts very much.

To properly start the engine saw engine, set the lever or switch to the “flap” position. Then you need to pump the mixture into the carburetor if there is a fuel pump in stock. Pull out the starting handle until the engine resistance becomes noticeable, and energetically extend the amplitude, taking your hand to the side. After two. Three such movements, the engine must first start, and then decay. If this does not happen, then it is necessary to transfer the lever to the position of half.gas or simply to the working position, and then continue to work the chainsaw in this mode. Many Pologaz chainsaws are recorded automatically when the air damper is pulled

Some models have an ignition with the key, it is important to make sure that it is turned on

If the engine does not start, the first thing to do. unscrew and check the spark plug. There are times when the plant fills the burner with fuel in the cold season. Then you also need to unscrew the candle, dry the combustion chamber with one plant, clean the spark plug, screw it up and repeat the start. It is advisable to immediately check the presence of a spark. On a twisted candle, we put on a cap with a high.voltage wire, we put it on a cylinder, and we pull the starter. Visually observe a frequent blue spark. OK. We twist the candle in place and launch it. If there is no spark, change the candle and repeat the attempt. Again, no. Check the connection of the high.voltage wire to the spark plug, coil and ignition system.

In general, the condition of the candle can be used to determine the type of malfunction.

• Dry. Most likely, the fuel mixture is not included in the cylinder. This is not a ignition system, so the candle is screwed and checked.
• Wet, strongly sprinkled with fuel. The cause of the excessive fuel mixture is to violate the launch rules, as described above, or if the carburetor is incorrectly set up.
• Covered with black carbon. This may indicate the use of poor.quality oil, an incorrectly configured carburetor or an incorrectly calculated ratio of gasoline and oil. The candle should be washed, cleaned of carbon deposits with a sharp object (awl or needle), rub the electrodes with a fabric and installed in place.

When checking the light of the ignition, it is necessary to pay attention to the gap between the electrodes: Normal is considered from 0.5 to 0.65 mm. Damaged or worn gasket should be replaced. Correctly adjusted carburetor chainsaw provides its effectiveness at full capacity with the most economical fuel consumption

Correctly adjusted carburetor chainsaw provides its effectiveness at full capacity with the most economical fuel consumption.

The need for tuning a carburetor chainsaw is infrequent, since adjustment is originally performed by the manufacturer to achieve the optimal mode of operation. Adjusting screws are designed for a more accurate adjustment of the carburetor chainsaw, if necessary.

Among the causes of violation of fixing the adjusting screws are the most common:

• Strong vibration or damage to a protective cap. This rarely happens, but still happens.
• Serious engine wear (piston). Of course, in this case it is better to take care of repairing a chainsaw, but at the same time, adjusting the carburetor can improve its functionality for some time.
• Litter in a carburetor because of the low quality of gasoline or due to the formation of scale. In this case, in addition to adjusting the carburetor, it can be avoided.

Dismantling the lawn mower

I had to unscrew the lid on the housing of the lawn mower, under which the cable went on the side. But here, too, was awaiting difficulty. The screws of the screws were hidden in the depths of the secret holes and were tightly clogged with grass with the ground. After cleaning the heads of garbage, it became clear that they were designed for a cross screwdriver, but all attempts to unscrew them with such a screwdriver were unsuccessful.

Managed to display them with a screwdriver with a flat sting. It turned out that the center of the Schlitsov was raised and the cross screwdriver did not fully enter the engagement. Another protection against independent disassembly.

After removing the lid, it was found that the cable was recorded by four self.tapping screws of the same size, but with normal slots. Therefore, to exclude difficulties in unscrewing the lid in the future, rusty screws that previously hold the lid were twisted into cable clamps.

After many years of work, a lot of mowed grass accumulated inside the lawn mower, which wrapped the connectors and the start.up capacitor. I had to remove it to continue the repair.

After cleaning the lawn mower, access appeared to the connectors. To dismember the connector coming from the switch, it was enough to take the latch with a flat screwdriver to the side.

In the lawn mower, an asynchronous single.phase electric motor was installed, not having a collector and brushes. Thanks to this, there is no need for regular maintenance of the lawn mower. This lawn mower for ten years refused for the first time.

And then another malfunction was discovered, which did not show itself. When checking the freedom of rotation of the engine rotor by influencing the impeller, it turned out that it was not fixed on the shaft and easily starred.

The surface of the engine’s holes on the engine shaft was smooth. It seems that when spent, the knives fell on the branches, stones and, as a result of repeated jerks, the plastic of the impeller was cut off.

For reliable fastening of the impeller, the engine shaft was wound in one layer of a strip of a medical patch on a fabric base with a protrusion for the end of the shaft for 5 mm. Then, through a wooden gasket by blowing a hammer, the impeller is planted on the shaft. The landing was quite durable.

The breakdown of the circuit breaker unit in this case turned out to be good, since due to wear of the impeller mounting, the engine could burn out due to overheating and I would have to buy a new lawn mower.

Repair of malfunctions of an electric mower

Long grass that has wound on them can be led to jamming knives. For repair, you need to turn off the device from the network and twist the cylinder in the opposite direction.

If the electrical device is silent, the drive belt breaks the resulting result of wear: it can be stretched or broken off. This means that you can not do without replacement, for which you need to remove the protective cover.

The new belt is first installed on a small gear of an electric device, then, put on a large pulley, and turning it on.

To replace the power cable of this electrical device, it is necessary to de.energize the device and unscrew the lid.

To disconnect the cord, insert the hexagonal key into the hole with the wires, freeing the clamp.

The new power cord is installed in the reverse order.

The reason may also be hidden in a faulty power switch, which is simply replaced by a new.

The reasons

The main reason for the malfunction in the work of the mechanism can be called the application for other purposes. Possessing knowledge about the principle of work and mechanisms of garden equipment, it is possible to eliminate problems with your own hands. But it is still better to contact a specialist, especially with serious breakdowns. Among the breakdowns that are most often found, the following can be distinguished:

Unusual garden technique noise. This is usually due to weakening the bolts or poor fixing the body. You need to carefully examine all the nodes and twist the bolts. If the noise resembles a whistle, most likely an extraneous subject fell into the mechanism. It is necessary to turn off the mechanism and remove an extraneous object;

• The case is unnaturally shaking when working. Most likely, the reason is the malfunction of the cutting element that needs to be replaced;
• The lawn mower will not start. First you need to check the presence of a sufficient amount of gasoline in the tank. If everything is in order with this, and the engine does not work, a faulty ignition candle may be a possible cause. In other cases, it is recommended to consult a specialist, since it will not be easy to repair a mower on your own;
• The engine does not gain momentum and immediately stalls. The reason may be the jamming of the mechanism. If this happens due to lack of lubrication, you need to pour oil into the crankcase and put the mechanism into motion;
• The uneven surface of the lawn. This means that the cutting elements are dull and the grass is poorly cut off. It is necessary to sharpen the knives, and it is better to replace them with new ones;
• The lawn mower does not go or the movement is difficult. First of all, you should check whether the height of the mowing is selected correctly.

All of the listed malfunctions can be eliminated independently without addressing specialists.

Capture width is 46 cm, the height of the bevel is adjustable from 2.5 to 8 cm. The handle is folding, adjustable.

Characteristics

A small amount of oil in the fuel mixture

First we analyze the most unpleasant incident. Why? Because before making filters manipulations, it is better to make sure that oil and gasoline are mixed in the correct ratio.

Here, however, it is worth noting that if your saw was repeatedly (for example, ten times), you were drawn, but continued to end, and then stopped again with an increase in speed, then fuel, probably, is all right, otherwise it was simple would stop beating in general.

Nevertheless, I recommend that you immediately eliminate the slightest doubt as fuel as soon as you drink your kiosk during the first speed set. Because if the cause is fuel, then, as mentioned above, you can get to an expensive repair. Thus, you can still do. To dispel doubts, you need to drain the old fuel from the tank and fill the freshly prepared, in which oil and gasoline are mixed in the correct proportion.

The correct ratio is better to see in the instructions for the saw. If it is lost, we will look at the ratio of oil packaging. This is usually 1:50 or 1:40. If the oil is used “non.native” (well, for example, for the Stihl “NATIVE” chainsaw there will also be a little STIHL), then I recommend using a 1:40 proportion, even if on a package with butter written 1:50.

Features of the use of garden technology

It should be remembered that grass can be mowed with a height of not more than 20 cm, by 1/3 part, at a time. Before changing the height of the bevel. be sure to turn off the car. You need to work especially carefully on the slopes, move along the area.
