Trimmer for grass gasoline Huter stalls at low speeds. The engine regularly stalls…

The reasons for the fall in the motorcycle. The lawn mower does not develop full power

Any person owning a country or land plot is well aware of the problems of the fight against excess vegetation. Now a trimmer for the grass has come to the rescue, which successfully replaced the usual braid in this field. This unit is very convenient in work, but it, like any mechanism, also, due to difficult working conditions or incorrect operation, is characterized by failing. Situations are quite common when a trimmer for grass does not gain momentum. To understand this problem, it is necessary to understand some aspects related to the functioning of the device.

All trimmers for grass are classified according to the type of power: gasoline or electricity (from the network or battery). It should be noted that gasoline mowers in many respects exceed their electric and battery analogues. Despite the fact that they all perform similar functions, the difference in performance, maneuverability and effectiveness is very noticeable. However, the general principle of operation of all types of manual braids is almost no different- the devices are equipped with engines (two- or four-stroke ICE or electric motors), which drive the cutting unit (reel with fishing line or metal disk). All elements are fixed on the line of straight or curved shape, including the handle for controlling the trimmer on which the main buttons are located.

Since the problem of weak revolutions is more characteristic of gasoline trimmers, they will be given more attention. So, the lawn mower is very comfortable in work and unpretentious in maintenance. over, most of its malfunctions are caused by ignorance by the user of elementary things, which are written in the instructions. Therefore, before starting the operation of the unit, it is necessary to carefully study the management of the manufacturer. In particular, in order to start the engine, it is necessary to do the following sequential actions:

• turn on the ignition button;
• press the silicone button for pumping gasoline several times;
• close the air damper;
• The gas lever is installed in a position for high speeds;
• first make non.leaf with the starter handle to feel the engine resistance, then jerk sharply.

If the lawn mower started up, but stalled, you need to put the air damper in the middle position and repeat the attempt. When the engine works, you need to slow the gas and open the air damper, since the trimmer for the grass functions only on the leak.

Important! The mode of operation of the trimmer for the grass depends on the various environmental influences. In hot weather, the unit should be given more time to cool. When working in conditions of dense thickets or high vegetation, the engine also overheats strongly. It is necessary to take five-minute breaks every 15-20 minutes.

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.

Important! If the unit does not work due to breaking up the engine, serious problems may occur. In this case, the malfunctions that can be eliminated with your own hands include only the destruction of piston rings. With more serious problems with the motor, if there is no warranty, you should be prepared to visit the workshop.

What could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

• the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
• the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.

Ways to eliminate breakdowns

Subsequent work is likely on the carburetor:

• cleaning and adjustment of the fuel supply valve;
• similar work with a valve producing redesigned gases and pairs (after burning fuel);
• replacement of the spring more weak on the entrance valve;
• restoration of the tension of the carburetor cable;
• replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
• changing the rotor damper disk;.
• Change of faulty wire or ignition coil.

Immediately after the start

Smelting Motokos or a trimmer for the grass after starting is justified by subsequent reasons:

• impressive of previously adjusted valves;
• first the wrong settings of the valve mechanism;
• clogging with deposits of the fuel supply valve;
• the hose is worn or poorly annexed.

Due to the violated method of injection of a fuel, a lawn mower or a trimmer for grass is very vibrated in work.

Trimmer malfunctions for grass

Trimmer for grass is a convenient and affordable replacement for the lawnical mower. Its cutting part is made in the form of fishing line, knives or disk installed on the drum, which is closed on top of the protective casing. The basis of the design is a bar, which is adjustable in height, at the end there is a comfortable handle and shoulder belt.

Like any other technique, a trimmer for grass may be unknown, and so that the breakdown does not lead to the final failure of the tool, we suggest you familiarize yourself with this article. Unit can break down for various reasons. Breakage occurs both in new trimmers and those that have long been operated.

A malfunction of electrical models

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

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

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

Motor malfunctions occur when overheating of the lawn mower:

In the first case, it is recommended to wait a few minutes so that the motor cools. In the second case, you need to remove the stuck object. The effectiveness of the cooling system depends on the state of the air filter.

Dirty device poorly passes air, which helps to turn off the device. Experts advise cleaning and changing the filter once every 3 months (with constant operation of the lawn mower).

With a breakdown of the electric motor, the corresponding smell and noise appear. In this case, you need to replace the drive.

The vibration of the motor on idle, on a cold or warm engine: possible causes

Immediately note that there are many reasons for the emergence of vibration of the internal combustion engine, starting from the torn engine pillows (supports) and ending with ignition passes and the tag of power unit. For a more accurate definition, first of all, you should pay attention to one or other symptoms.

The fact is that vibration can be either constant (regardless of heating and loads on the unit), and manifest itself in a certain mode of operation (idle or high speeds, on cold or hot). Another engine vibration can manifest itself on a cold ICE, but as it warms up, it completely disappears. Let’s understand.

• For example, if the engine was recently versed for repair (possibly capital), then there is a high probability that the crankshaft was not properly covered after the reverse assembly. The result is a beating and increased vibrations.
• We also note that after repairing the motor to imbalance and vibrations, different weights can lead to the details of the cylinder-piston group. The more weight difference turns out, the stronger the vibrations will be. For this reason, experienced craftsmen weigh pistons, fingers, etc.D.
• Often the reason for vibrations is that the engine is troit, that is, one or more cylinders for any reason do not work or work with failures. As a rule, the elimination of the cause of the touch automatically eliminates the presence of vibrations of the power plant.
• Do not forget that the timing belt incorrectly set on the marks or the chain also causes vibrations.The reason is that the engine works unstable due to violation of the phases of gas distribution.
• Many engines have in their design special balancing shafts that are necessary in order to “extinguish” fluctuations. Quite obvious, problems with these shafts will lead to an increase in the vibrations of the motor.

The engine pillows are one of the most common reasons why the engine vibrates. In fact, this is a damper made on many cars from rubber to absorb vibrations. As you know, over time, the rubber daggers and cracks, loses its properties as a result of technical fluids and t.D. The main thing is that the engine with a damaged pillow cannot work softly.

• If you recently moved from one car to another, it should be borne in mind that different engines may differ in vibration loads. The number of cylinders, layout and a number of other features affect the level of vibrations. In simple words, the usual in-line engine for 6 cylinders can operate with less vibrations than a 4-cylinder and, especially, 3-cylinder engine. over, in this case, we are not talking about problems, since for a particular ICE a certain level of vibration can be considered the norm.
• We also add to reduce vibrations, on the crankshaft of many engines there is the so.called dignified damp. If problems arise with the element, the motor will begin to vibrate more strongly.

As you can see, at the initial stage it is important to accurately determine the cause of the strengthening of vibrations. For example, in most cases, it is enough to replace the engine support or solve the problem on which the engine is troit. However, it also happens that the power unit itself needs to be disassembled and repaired.

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:

The lawn mower stalls at high engine speeds

During operation, a situation arises when, when pressing the fuel supply key, the aggregate turnover begin not to increase, but to decrease. A malfunction of this nature can be caused:

Fuel hoses Motokos with filter

• etching of atmospheric air into the combustion chamber;
• problems with the circulation of a mixture of fuel;
• clogging the saapun in the lid of the fuel tank (cleaning the hole with a thin sewing needle);
• Incorrect carburetor adjustment.

When air sunses, when I operate ICE, it is necessary to check the tightness of the pipes and the integrity of the gaskets in the CPG. The problem with the circulation of the fuel mixture can be solved by the elimination of blockages in the fuel pipes leading to the carburetor. If a vacuum occurs in the tank and not receipt of the fuel mixture to the carburetor, it is enough to clean the soundtress with a thin needle and blow it with air.

Why is the lawn mower stall at idle

Users have repeatedly ask about stopping the braids for the grass “on hot”, that is, when the mechanism started, worked a little, and then took it. and stopped, stalled. The reasons for this situation are the following:

• problems with the carburetor damper;
• Gasoline in a carbe can even boil;
• If the ignition is damaged, then the trimmer for the grass will also heat up and stall.

In each of the situations, check the details for strength, and if they have already outlined their own, order new ones from specialists. We will call one of the most popular situations: the lawn mower stalls at idle. This happens for reasons:

• The carburetor was diluted himself, or was illiterately adjusted;
• the carburetor is contaminated;
• The air filter is very contaminated;
• The use of inappropriate fuel can cause a reduction in the gearbox revolutions;
• At idle, your trimmer for grass can stall if the throttle closed;
• Air fell into the carba system;
• The lawn mower receives a missing portion of gasoline to work fully, and therefore stalls.

We are sure that you received the maximum of useful information, and found a way out of your individual situation through our technical councils. Any spare parts, like a starter, motorcycles, its components and accessories are located at the lowest value in the country. Hurry up!

Immediately after you started

The unit can stall immediately after the launch, if the carburetor is cesspool or was incorrectly configured. this causes Uneven fuel supply

The result is that the device begins to vibrate clearly. To eliminate problems, the carburetor is reconfigured, acting according to the instructions for the mechanism.

The engine also stops when Clotting of the valve

, supplying fuel. In such cases, it is enough just to clean it. If the lawn mower at first earned, but then immediately stalled, then possible fuel to the carburetor unit enters some difficulty. The weakening of the valve helps to solve the issue, which provides free circulation of the mixture in the system.

The stop may also be called Air suction

In the presence of mechanical damage to the hose (holes, cracks) that fuel fuel fuel. In this case, the drive should be added to the drive to quickly drive air bubbles from the system.

When opening an air damper

It happens that the unit stalls when opening an air damper, working normally at idle. This is due to the air leaks of the system caused by the presence Cracks of the fuel hose

or problems with seals. The carburetor dosing system can also work malfunctioning, while the lawn mower will stop after the opening of the damper.

All possible reasons that the lawn mower stalls, and the methods of eliminating them are contained in the next video

There are many reasons for stopping Motokos, but the most commonly occur in work related to its carburetor. They can arise in any case. The most problematic option is when there is a serious breakdown, and you will need to purchase new parts or change the lawn mower.

So that the trimmer for the grass works normally for a long time, you should strictly comply with the requirements of the operating instructions. It is necessary to refuel the unit suitable for it in the composition with a fuel mixture, the device should work with a moderate load.

What is the resource of Chinese motorcycles?

Chinese or lawn mower is able to work about 500 mothers. But this is with the correct mixture, good oil, a good factory assembly. If a person fills gasoline with one good refueling, accurately measures the same oil along the Menzurka, the carburetor regulates the same mixture, the fuel burns correctly, then the coveted half a hundred hours of motor resources is a very affordable bar.

But here you can’t also forget about Chinese marriage. They even balance the shafts on their knee, put the cheapest bearings, carburetors stamp with clogged channels. If a person understands the principle of operation of a two.stroke engine and carburetor, understands how to sort it out, then he can eventually collect an almost perfect trimmer for grass.

In general, if we consider the Chinese motorcycle foam as a space for creativity, then even its breakdown is an occasion to study something new, this is a designer for a man.

If you need a tool, then it is worth finding a Japanese analogue, or switch to an electrical model.

Methods of elimination

Repair of a lawn mower is best started with a phased check of the main components. The first thing to check is fuel in the tank, as well as the presence of lubricants on the main nodes of the tool

It is also important to know what quality and what is the proportion of the fuel and oil used. If something is wrong, then the piston system may fail, and its replacement is expensive

Next, it is worth evaluating the serviceability and performance of the spark plugs. The result is evaluated by the presence of a spark when there is contact with the tool body. If the malfunction in the candle, then you need to remove the voltage wire from it.

In case of contamination, it is recommended to replace with a new one and drying the candle canal. This is also done if there are cracks or chips on the candle housing. The gap between the electrodes is set 0.6 millimeters. Squeezing a new candle is also produced by a special key. At the end, the voltage wire must be connected to it.

The inspection of filters, both fuel and air. If the blockages are strong, then the best solution will be their replacement. You can try the air filter with water with the addition of a detergent, and then dry. It is also sometimes soaked in gasoline

After drying and installation, it is important to moisten the filter with oil, which is used in the mixture with fuel

It is very easy to eliminate the problem in the form of a stalling lawn mowed immediately after starting. it is enough to adjust the carburetor according to the scheme given in the documentation. Sometimes you have to send the valves of the carburetor to facilitate the supply of the mixture in it.

Sometimes the lawn mower stalls due to the receipt of a large amount of air. In this case, it is necessary to increase engine speed to release it. It is also necessary to check the fuel hose for possible damage. If necessary, it is changed to a new.

It is important to maintain a gearbox clean, and its gears should always be treated with a special lubricant. It is worth noting that it is not always possible to repair a gearbox and starter on your own, therefore it is more advisable when breaking down these nodes to replace them with new

When reducing the engine power, it is worth paying attention to the exhaust muffler, or rather, to the net in it. She can clog because of soot from burned oil

This malfunction is solved cleaning the grid. You can do this using a small brush with wire or nylon bristles, as well as compressed air.

Clutch in benzocoses can break due to wear of the pads or a bursting spring. In both cases, the failed spare parts are replaced. Sometimes the clutch coupl is unusable, it can also be replaced with a new. over, on sale there are both couplings in full assembly and individual elements to them (washer, drum, etc. D.).

Why and what to do if a trimmer stalls for grass

There are several reasons why the trimmer for grass stalls when the grass. Usually the problem is provoked:

• wear of engine elements. piston, bearings, crankcase;
• malfunctions with fuel supply. a carburetor can fail in the device, sometimes a malfunction causes a clogged filter;
• mechanical damage to hoses, tubes and cables;
• disobedience with the ignition chain.

Most often, under a load for one reason or another, an old trimmer for grass, which has long been in operation, stalls for a particular reason. But sometimes the owners of new gasoline devices face problems.

Why is a trimmer for grass stalling when pressing gas, increasing speed

If the trimmer for the grass stalls when you give gas, then the problem is usually a malfunction of the carburetor adjustment. The malfunction often occurs if the device was inaction for a long time, and then received a significant load. Sometimes the unit stalls immediately after increasing speed, if before that it was operated in difficult conditions with violation of the rules.

The following reasons are also leading to problems with the performance of the device:

With stretching or rupture of the fuel hose in the gasoline trimmer, the elements that have become unusable must be changed. If the reason is in the clogged valves and filters in the unit, they are quite simple to clean.

If the reason that the trimmer stalls for the grass is caused by problems with the carburetor, the problems are accompanied by vibrations

Another common problem is that the trimmer for grass stalls with increasing speed due. In this case, you need to find the instructions for the device and carry out the reconfiguration of the unit. Often it is enough to weaken the tightening of the carburetor body.

Why does a trimmer for grass stall at idle

Garden trimmer for grass often stalls even at idle. The reasons for the malfunction are usually simple. First of all, the improper adjustment of the carburetor affects performance. it leads to problems both at high speeds and in idle mode. Turning off the device can provoke clogging of an air filter or throttle.

Sometimes a trimmer for grass stalls if incorrect fuel is used for it. The gearbox for this reason overheats and reduces momentum.

If a malfunction occurs, it is necessary, first of all, to inspect the carburetor unit and perform mechanical repair or configuration. If the cause is of poor.quality fuel, you need to replace the mixture with a more suitable.

What to do if the trimmer for the grass starts and immediately stalls

If the trimmer for the grass does not gain momentum and stalls immediately after starting, the problem usually consists in improper tuning the carburetor. In this case, fuel in the system comes unevenly, the gasoline unit vibrates and cannot work normally. Repair consists in reconfiguring a carburetor unit according to the instructions from the manufacturer.

Engine stop causes fuel supply valve. The element must be carefully cleaned, and then installed back in place. If the lawn mower still stalls immediately after starting, perhaps the valve is too tight and it needs to be loosened. In this case, the fuel mixture will begin to circulate through the system freely, and problems with the performance of the unit will disappear.

In some cases, a gasoline trimmer for grass stalls due to the fact that the hose contains damage that pass the air. During the repair, you need to replace the fuel tube with a new.

Attention! If the damage in the hose is insignificant, it is allowed to simply add a revolution drive. This will allow you to drive out air bubbles from the fuel system.

What to do if the trimmer works and stalls for the grass

Owners of garden gasoline units are faced with the fact that a trimmer for grass stalls at large speeds after a short work. First, the device begins to function with jerks, and then gradually stops.

Typically, the reason is the overheating of the system. gasoline in the carburetor simply boils. A trimmer for grass can heat up if the ignition circuit coil or wire is damaged. There is no point in repairing worn details, they are simply changed to new working.

The use of a trimmer for the grass does not lead the use of not disk, but rotary damper in a carburetor

What to do if the trimmer for the grass overheats and stalls

If a hot trimmer stalls for grass, the situation is a great danger to the performance of the unit. Repair should be carried out immediately, otherwise the device will be completely unusable, and it will be more difficult to restore it.

Overheating of the unit usually cause the following reasons:

• The use of inalitions. pour fuel into the tank with precisely with such an octane number that is recommended by the manufacturer;
• a large amount of air in the system. for this reason, the enriched mixture releases an excess of heat;
• non.compliance with the proportions of oil and gasoline in the preparation of fuel;
• The thick layer of soot on the muffler. soot is a good heat.insulating material, the gasoline braid for the grass during operation is very hot and stalls;
• The displacement of the axis of the spit.headed head inside the bar. for this reason, the rotation slows down, and the load on the engine increases.

If the gasoline unit stalls, you need to carefully examine it and eliminate first of all possible deformations of the structure. Then it is necessary to study the fuel parameters. If they do not correspond to the recommended, gasoline is replaced with a more suitable. If unnecessary air gets into the system, it is necessary to independently or with the involvement of specialists to adjust the position of the carburetor damper.

Sometimes a gasoline trimmer for the grass overheats and stalls because there is too old fuel in the tank. Use a fresh mixture for the unit, which was stored no longer than two weeks.

Attention! A trimmer for grass will overheat if you use it for too long, or mow with a weak device hard thick grass.

How to avoid breakdowns

Many breakdowns of a gasoline trimmer for grass can really be eliminated if you remove the causes, but if possible, it is recommended to, in principle, avoid faults. Simple measures allow to maintain the unit in a working state:

• You need to use a trimmer for grass in accordance with the recommendations of the manufacturer. It is impossible to use a weak device for removing hard weeds on the site, it is also not recommended to use motorcycles in excess of the due time. The gasoline unit needs to be turned off regularly and allow it to cool down.
• During the operation of the device, it is necessary to monitor the state of the cooling system. To maintain performance, the channels in the case are regularly cleaned, like the starter’s ribs. The clogging of the system often becomes the reason that the unit stalls from overheating.
• After using the gasoline trimmer for the grass, too, you need to clean. In this case, the procedure is not carried out for a hot unit, at first it must completely cool. For cleaning, use solvents, kerosene and other products allowed for use by the manufacturer.
• Before cleaning, the motorcycles for storage must be drained from the tank, the remains of unused fuel. If this is not done, the gasoline mixture will fall into heavy components and will clog the channels of the carburetor, which will subsequently cause malfunctions. After draining the fuel, the device is launched at idle and waited for it to turn off.

With the onset of autumn, a gasoline trimmer for grass must be correctly removed for storage. First, the residues of the fuel mixture are drained from the device, and then the unit is disassembled, rinse and clean all removable components.

Before cleaning gasoline motorcycles for storage, you need to evaluate the condition of its parts, carry out the necessary repair and replacement of nodes. Air filter needs to be cleaned. The engine is partially disassembled, rinsed and blown by moving elements, and then applied a new grease. To maintain the piston part, the candle is unscrewed and the piston itself is lifted to the top point, and a little oil is poured into the opening opening and the crankshaft is twisted several times.

Store a gasoline trimmer for grass in winter is necessary in a warm room

Typical malfunctions of electric trimmers

Electric motor. a device, as they say, massive use, for the user, acquaintance with him usually takes place at the level “clicked on the button. and spun”. If it did not spin or, worse, smoke. the road is either to the service or for the tool. At home, you can usually only check the contacts or replace the brushes (there are no brushes on many engines and brushes).

Some models may contain additional elements: a device for maintaining a uniform speed of rotation, regardless of the load, fuses for protection against overload and short circuit, some kind of LED indicators (especially battery varieties), smooth starting devices (characteristic precisely for powerful motos ). All this is useful, but at home is not regulated, it is not repaired and very rarely deteriorates. Some manufacturers put everything that is needed by default: in the end, we are talking about a small and inexpensive electronic circuit located next to the motor. The motors themselves are generally the same.

With a gasoline engine, everything is much more complicated. “Classics of the genre”. a light and inexpensive two.stroke motor. gradually losing ground. There is only one reason. the discrepancy between environmental standards. Many manufacturers are gradually starting to switch to more complex and expensive motors. Their higher initial cost is compensated, in particular, by saving on fuel with prolonged work: after all, gasoline is also expensive, and in the “two.stroke” a considerable part of it is simply lost. “Inappropriate expenditure” of fuel can be significantly reduced if you mix fuel well in the combustion chamber and create optimal conditions for its combustion. You can also blow the cylinder with air before the release of each new portion of the mixture to completely remove exhaust gases from the combustion chamber.

These two technologies are now used in the production of new two.stroke engines. Different manufacturers can call them differently, but these developments provide compliance with at least Euro 2 standard. In some countries, the sale of equipment with ordinary two.stroke engines is simply prohibited, we have no such restrictions yet. The engine does not have an important technical differences for the user, that is, there are many differences, but it lends itself poorly to repair at home. Anyway, in everyday life, the engines “die” more often from improper operation than from wear or miscalculations when constructing. There can be more “outside” differences, as always, the design and features of the maintenance of air and fuel filters and the availability of light starting systems are interesting: additional springs in the starter, primer, and sometimes automatic decompression or decompression valve (these are different systems, the valve is pressed manually, “automatic” can only be seen when disassembled).

On motokos, four.stroke engines are sometimes installed. They are more reliable, environmentally friendly, do not require adding oil to gasoline and draining the fuel mixture from the tank before storage. In addition, such engines are less noisy, and the sound of the exhaust is not so harsh. True, for a four.stroke engine, it is required to introduce a gas distribution mechanism and a separate lubrication system with engine oil, as a result, the design is complicated and weighted. Yes, and the work of the timing requires additional engine power, which means that the output power will slightly decrease. In addition, the usual “four.stroke” cannot be highlighted: if the oil supply to the details stops, the engine will fail. Only in recent years, quite light and compact motors have appeared that could work at large angles of inclination, almost as light as two.stroke, but with a large resource, which is important for professional technology.

Such motors produce several companies, the design can vary in methods of saving oil in the crankcase when tilted and its supply to the valves. There are intermediate options: “four.strokes” working on the fuel mixture. They do not need motor oil, the lubrication of parts occurs, like any two.stroke, due to the oil in the mixture.

There are only two types of rods: straight and curved. And here there is a significant difference between trimmers and motorcycles: the motorcycle has a shaft inside the motorcycle. That is why the motorcycle rods look quite simple: a steel or aluminum tube with a diameter of 22-28 mm. The shaft for a curved bar, of course, should be flexible, a forged rod is often placed in a straight line as a shaft. The shaft rotates on bearings and is supported inside several additional supports, most often with bushings, but ball bearings also come across.

A fully collected braid for grass has a length of 1.5-2 m, transporting and storing it is not always simple, at least in the trunk of a car, it will most likely not enter-you will have to lay out seats. Some models are available with detachable rods. This at least save space, and many braids for grass can attach additional nozzles, for example, a bush, a minultivator or a chain saw. altitude. It should only be taken into account that a detachable bar is another knot, its elements can break, and such a braid for grass will cost a little more expensive.

A separate type of motorcycle. ranger. The engine is attached behind his back, a flexible bar is coming from it, which is connected to the hard. They are not used in everyday life, but for professional work they are convenient.

Typical malfunctions of gasoline trimmers

The engine of the trimmer for the grass does not start. The causes of the problem can serve as a malfunction in the system of ignition of a trimmer for grass or the use of poor.quality fuel (mixture).

• The use of poor.quality (counterfeit) gasoline, contaminated with various impurities;
• The presence of water in gasoline;
• Excessive fuel level in the tank (cylinder);
• The use of fuel mixture with incorrect proportions of gasoline and oil.

Characteristic problems in the ignition system:

• Damage or pollution of the spark plug;
• Incorrectly exhibited gap between the electrodes of the candle. The easiest way is to replace the problematic candle of the new or seek help from specialists.

During the operation of the engine, characteristic knocks are heard. The cause of the knock can be a damaged cylinder, crankshaft or bearing. All damaged parts should be replaced by serviceable. If a metallic knocking trimmer is a metal trimmer when working, it is quite possible that you have chosen the wrong type of fuel mixture (gasoline with oil or gasoline with additives). The mixture should be drained and replaced by the correct. In addition, extraneous sounds can make an overheated engine that has been continuously working for a more set time (usually a safe period is 15 minutes).

The trimmer ignition system for grass is faulty. Such malfunctions are caused by water that falls into the fuel mixture or problems with the spark plug.

Suddenly stalls the engine of a trimmer for grass. Typically, such reasons are caused by the absence of a fuel mixture in the tank, a malfunction of the candle or damage to the high.voltage wire in the ignition system.

Immediately after you started

The unit may stall immediately after starting, if the carburetor is shifted or incorrectly adjusted. This causes an uneven supply of fuel. As a result, the device vibrates clearly. To eliminate defects, the carburetor is reconfigured, following the annotations to the mechanism.

Apart from that, the engine stops when clogging the fuel supply valve. In such cases, it is quite easy to clean it. If the bureau at first earned, but later stalled immediately, then maybe the fuel with some difficulty falls into the carburetor knot. Weakening of the valve helps to solve the issue, which ensures free circulation of the consistency in the system.

The stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks), taking fuel. In this case, increase the speed of the drive in order to resign more air from the system from the system.

Where to look for a reason or where to start checking

All chainsaws have the same design, and work according to one principle. The device of the chainsaw can be found in this material. It does not play much meaning which brand of the tool. Stihl, Husqvarna, Echo, Champion, Partner, Sturm and others. A malfunction manifested in the form when a chainsaw is stalling when pressed on gas can arise the same both on expensive and high.quality tools and on budget Chinese devices. If the problem has arisen, then it needs to be solved.

A chainsaw is a system of mechanisms consisting of details. Any detail in the mechanism can fail, which will lead to a partial or complete failure of the tool.
