Review of Stihl FS 55 – the ideal light-motor mower

If you often encounter the need to mow the grass on your property, then you can use modern devices such as trimmers or lawn mowers specifically for this purpose. Among other solutions on the modern market, there are lawn mowers that can be used to maintain the surrounding area in a well-groomed condition.

One of the important advantages of a lawn mower is that it is not tied to a power source according to the principle of electric units. But such equipment can be used even on uneven areas and in hard-to-reach places, this should include areas under bushes.

A gas mower is safer, since the use of electricity is always accompanied by the possibility of electric shock. The main condition is the correct choice of braid. To do this, you should familiarize yourself with at least one of the models. Among others, the market presents the Shtil FS 55 lawn mower, reviews of which should be read before making a purchase.

Stihl brand – technology in leading positions

Gasoline trimmers from the German brand Stihl are especially in demand among domestic consumers.
Divided into amateur and professional devices, equipment of these types is distinguished by high build quality, durability and particularly ergonomic design.

When making a swamp vehicle with your own hands, caterpillars play a very important role.

And here you will find out which engine is equipped with the IFA Multicar 25 truck.

Amateur equipment includes such models of Stihl petrol trimmers as FS 38, FS 45, FS 55, FS 70. The main feature of these trimmers is that they can be used in small and medium-sized areas.

This possibility is determined by the power of the gasoline engine (from 0.9 for the FS 38 to 1.2 hp for the FS 70) and the volume of the fuel tank (0.33-0.34 l). The cutting tools in these models are a knife, a disk, and a fishing line.

The category of more powerful trimmers includes models of petrol trimmers Shtil FS 130 and FS 250, used for long-term work with hard dead wood, bushes, difficult to mow tall grass and trees with a small trunk diameter.

The power of this equipment ranges from 1.9 to 2.15 liters. s., and the engine capacity is 36-40 cubic meters. see. Amateur and professional devices of this type are characterized by the possibility of use in areas with terrain of any complexity.

Mowing grass on overgrown slopes and in ravines is not a problem for this type of garden equipment. This determines the fact that trimmers often perform the final treatment of lawns after a lawn mower.

About the manufacturer Stihl

The history of this German brand begins in 1926. At the initial stages of its development, the company was engaged in the production and sale of various components for washing and steam machines. It all started, like many companies, with small production and a narrow focus, which made it possible to focus on the quality of the products produced.

In the early 30s, the first STIHL chainsaw was released, distinguished by its convenience and functionality even in those days. The company is developing at a rapid pace, constantly introducing new tools, which gives it the opportunity to enter the international market. And already in 1931, the first regular deliveries of products to Russia were organized.

To date, the company has expanded its activities in more than 160 countries around the world, opening new centers and production branches in Switzerland, China and many other countries. This is understandable, because the company’s assortment is impressive: motor drills, gasoline sprayers, mowers, gasoline trimmers, chainsaws and much more. I would like to note that Shtil chainsaws are very popular due to their functionality and reasonable price.

Advantages and disadvantages of the Stihl FS 55 trimmer

The Stihl FS 55 brush cutters have a number of pros and cons.

The list of advantages of the model includes:

• high reliability and endurance - the engine, carburetor and other mechanisms of the Stihl model are able to withstand high loads even when operating in extreme weather and operating conditions;
• ease of use and operation. Running in the model is quite simple - the operator just needs to not overload the trimmer motor during the consumption of the first 2-3 tanks of fuel. Further use of the brush cutter does not require specific skills. Free access to frequently replaced trimmer elements makes it possible to quickly lubricate rubbing mechanisms and replace faulty spare parts;
• high speed of operation and modest fuel consumption - on average, it takes the trimmer no more than 1 hour to mow 1 hectare of land. For this, the lawn mower requires no more than 200 ml of fuel mixture.

Among the main disadvantages of the model it is necessary to highlight:

• small volume of the fuel tank - because of this, the operator needs to frequently interrupt work for additional refueling;
• possible problems with starting with a small amount of fuel in the tank. To avoid this, the owner of the Stihl lawn mower is forced to constantly fill the fuel tank;
• a rapid drop in power when the air filter is dirty - in this case, dust and debris must be removed from the filter, which requires additional time.

Another disadvantage is the urgent need to take into account the height at which the Shtil FS 55 brushcutter is used in flat and mountainous areas. The higher the altitude, the more oxygen in the air. Accordingly, the owner of the scythe needs to constantly change the carburetor settings. Otherwise, the risk of damage to the CPG of the Stihl trimmer increases.

Problems and solutions - DIY repairs

But what to do if suddenly it was not possible to avoid a breakdown of the mechanism? We won’t go into the reasons for this, but it would be useful to consider possible problems that may arise with the mower, as well as methods for eliminating them on your own.

The engine does not start. If you encounter this problem, then you first need to assess the amount of fuel in the fuel tank; maybe there is no problem as such, but you just need to add fuel and continue working. By the way, the fuel used deserves special attention, because the service life and quality of operation of the lawn mower depend on its quality. Experts recommend AI-92 gasoline, no lower.

Stiga robotic lawn mowers are an innovation in the agricultural industry that have managed to win the hearts of many farmers and summer residents.

A homemade circular sawmill is easy and simple, thanks to the detailed instructions that you will find on this site.

If you asked yourself the question: “How to choose a professional saw without having experience working with this tool?”, then here you go //machinspec.com/lesozagotovitelnaya/benzopila/kak-vybrat.html.

Another likely cause of unstable engine operation may be a dirty fuel filter. You should carefully inspect it and clean it if necessary. If the filter cannot be repaired yourself, you should replace it with a new one.

Do not forget about the air filter, clogging of which can also lead to failure of the tool. In order to avoid this, the part is removed and washed in water with detergents, or in gasoline if there is no access to a water supply.

Then the filter must be thoroughly rinsed and dried, carefully monitoring the integrity of the structure. Before installing the part into the mower, it is necessary to lubricate it with a small amount of oil. However, if you don’t want to bother with cleaning the unit, then we suggest that you familiarize yourself with a lawn mower with a mulching function, because it will not only cut the lawn, but also prepare further fertilizer.

The spark plug can also affect engine performance. It is necessary to unscrew it and check the condition, if necessary, replace it with a new one.

If after all the manipulations done, the engine still does not start, then you can resort to the advice of experienced craftsmen who have used them in practice.

It is necessary to adjust the speed using the carburetor screw. The mower is placed in such a way that the fuel hits the bottom of the carburetor. To do this, place the tool so that there is an air filter on top.

Next, you need to remove it and pour some fuel into the carburetor, then install all the parts in place. The engine should start.

You can pull the starter handle while closing the carburetor choke. Next, open it and pull the starter a couple more times. This is a fairly universal method, proven over the years.

These tips are not a panacea, but they are quite effective and useful.

The mower stalls immediately after starting. The main cause of this problem is incorrect carburetor adjustment. It is quite simple to determine this problem - strong vibration will be felt when the mower is operating. You can fix the problem yourself by looking at the instructions, which describe the problem and solutions in detail.

Particular attention should be paid to the fuel channel; it is often the reason that the tool stalls. Check it regularly and clean it from dirt.

Various small parts, such as a cable or fuel pickup hose, can affect the stable operation of the tool. Therefore, you need to monitor their condition, check for cracks and small punctures.

Many may be put off by the relatively high prices of Shtil products, but if you think about it, what is more important - reliability and good results or savings that come at the expense of quality? But, if you set out to save money, then we offer you the option of a do-it-yourself lawn mower; by assembling the device with your own efforts, you will know all the nuances and structure of the tool.

Of course, you can choose cheaper Chinese analogues, but then no one will be able to vouch for the result of the final work and for the service life, which can be very short for such models. So it is more profitable to purchase a mower once from a reputable company, which Shtil certainly is, and enjoy stable operation over many years of operation.

Advantages of gasoline trimmers

Lawn is different from lawn. If there is a small well-groomed lawn in front of the windows of the dacha next to a flower garden, sometimes hand-held mechanical tools are enough. Although judging by the reviews, summer residents still prefer electric tools. But if the plot has just been acquired and the flowerbed still needs to be formed, or when the dacha was “inherited” and the lawns are in a deplorable state, light equipment is not enough.

It is clear that to cut tough grass stems, and even more so dead wood or woody shoots, you will need not only a strong cutting blade, but also sufficient power. And the latter is determined by the speed of the shaft rotation and the transmission of force, which, in turn, requires high motor power. Electric and battery-powered engines simply can't be that powerful.

• But trimmers from Stihl, equipped with gasoline engines, are excellent for solving such problems. Here the motor power can vary from 0.3 to 2 kW and higher. And this, as evidenced by reviews from both experts and tool owners, allows you not only to cut off dead wood, but also to process large areas: playgrounds, lawns behind the house, even park lawns.
• The second undoubted advantage is independence from the network. The area being treated is not always located directly in front of the house. A gasoline engine and a fairly decent fuel tank, such as those found in, for example, the Stihl fs 250 lawn mower, allow you to work without stopping for more than an hour, and the distance to home does not matter.

The main disadvantage of the trimmer is a fair amount of noise. The engine is equipped with an air cooling system, which eliminates sound suppression, which is about 95 dB. Therefore, it is necessary to work with headphones.

Anti-vibration protection on Shtil devices is mandatory. Even the lightest tool in the line, the Stihl fs 55 lawn mower, is equipped with a single-point vibration suppression system.

Starting the engine

The engine is started at a distance of 3 m or more from the place where the device is refueled. This work cannot be carried out indoors. Before you begin, you need to take a stable, reliable position. At the same time, the motorized device is held as firmly as possible. The cutting tool must not come into contact with the ground or objects, as it may rotate when started.

The unit is operated by only one person, and there should be no unauthorized persons in the area with a radius of up to 15 m. Otherwise, you may be injured by thrown objects. Starting the engine of the Shtil FS 55 lawn mower, the characteristics of which are presented in the article, should not be done by hand. After releasing the gas lever, the cutting tool will move for some time by inertia. Flammable materials must be kept away from the hot flow of gases and the surface of the hot muffler, as this may cause a fire.

Lightweight devices

Shtil company offers both household and professional devices. The price of the product depends on its technical characteristics. In addition to the standard equipment specified in the model descriptions and detailed instructions, additional accessories for various jobs are always offered.

Light models include the Stihl fs 38 lawn mower. Its fuel tank capacity is small - 0.33 liters, which provides about half an hour of continuous operation. The power of 0.65 kW allows you to easily mow young and already grown grass. The working tool is a mowing head with a fishing line. The head rotates 260 degrees, allowing you to treat lawn edges near borders and narrow strips of grass between flowers. This is a lightweight - 4 kg, and maneuverable device for flower beds. It is shown in the photo.

• Model fs 55, slightly more powerful - 0.75 kW with the same fuel tank volume. Comes with a blade for cutting grass. This option can successfully control weeds – but not dead wood or long-grown grass. The device weighs more - 5 kg, and is equipped with a two-handed handle. Care and replacement of knives are described in detail in its instructions.
• The fs 55 has a modification with a mowing head - 55 R. Here the handle is round, since the device is designed for maneuvering between flowers and bushes.

Semi-professional models

This includes trimmers that feature both more powerful engines and larger tanks.

• The first in the series is the FS 70 CE model. With such a tank volume, it has a higher power - 700 W. Supplied with trimmer head and cutting knife. The device allows you to mow young, overgrown grass and weeds; it is optimal for those cases when you need to tidy up an abandoned, albeit small, lawn. Its price is the lowest in this category.
• Petrol mower Stil fs 130 – with a light weight of 5.9 kg, it has a high power of 1.9 kW. The product kit includes a mowing head, a cutting knife with three blades and a cutting toothed disc. Replacement of elements is described in the instructions. The high power of the device allows you not only to cut grass and remove weeds, but also to fight reeds, dead wood and safely trim young shrubs. This universal option is suitable for both large lawns and areas with wild grass. Judging by the reviews, the model is one of the favorites.

The fs 250 is characterized by lower power - 1.6 kW, but a larger fuel tank - 0.64 l. The set includes a trimmer head and a cutting knife with two blades. The petrol mower is used for cutting grass, removing dead wood and young bushes. Thanks to the larger tank, it is heavier - 6.3 kg, but also lasts longer. This device is more suitable for processing large areas, such as a sports field.

In the video you can see how the devices work.

Stihl petrol trimmer: description, technical specifications

What is a gasoline trimmer? A petrol trimmer is a compact lawn mower. The name itself already suggests that it works using a gasoline engine, however, in addition to gasoline, it also requires refueling with engine oil.

The grass is mowed using the working part. It can be represented by various options, for example: a paddle knife, fishing line or other device.

The main advantages of this device, namely the Stihl petrol trimmer, are: ease of operation, light weight, compact shape.

Below are the technical characteristics of a gasoline trimmer.

Engine power directly determines the strength of the engine and the amount of fuel consumed for operation.

As for the classification of engines, they are lightweight (1 hp and less), simple (within a radius of 1-3 hp) and reinforced (more than 3 hp). If you want to buy a Stihl gasoline trimmer at a lower price, then a trimmer with a two-stroke engine would be an excellent option.

Its peculiarity is the need to mix engine oil and gasoline to start. But there is an alternative option: buy a Stihl four-stroke gasoline trimmer.

Its advantage is the built-in compartments for fuel and oil, as well as reduced noise and emissions.

To combat various weeds, bushes and other similar vegetation, blade knives are the best option. If you need a more affordable and safe method, then nylon fishing line would be it. The choice is yours.

Stabilization system and handles

The device is controlled and controlled using a handle that resembles a bicycle handlebar, equipped with buttons that are right at your fingertips. Also, for physical safety during operation, the Stihl gasoline trimmer is equipped with a stabilization, or in other words, anti-vibration system, which reduces the load on the hands and protects blood vessels.

Gas tank volume

A large capacity allows this device to work longer; however, it also adds additional weight.

Stihl petrol trimmer is the right tool for your garden! It is convenient to use, easy to use, high quality and effective.

Main stages of work (removing the carburetor)

The best option would be to watch a training video. Fortunately, there are dozens of them on the Internet. They will tell you everything in detail and professionally. As they say: “It’s better to see once than to hear a hundred times” (in our case, read). Schematically, this process can be written as follows: remove the protective cover, remove the rods and, finally, unscrew the unit to work with it.

Common malfunctions of the Stihl 180 carburetor

Malfunctions that can be solved by repairing the carburetor: It is worth noting that diagnostics cannot always correctly indicate the problem. There are times when the same “symptom” occurs due to different reasons. And sometimes diagnostics can give false information, as a result of which you will not be able to correctly eliminate the cause of the breakdown. Pay due attention to diagnosis, but do not overestimate its importance.

The tool does not hold idle speed, and sometimes the speed “walks”. Most likely the idle jet is clogged. It is urgent to clean it, otherwise the saw will not be able to perform its functions. Another possible cause is a malfunction of the fuel system.

Sometimes this problem is solved by cleaning the valve that restricts the fuel tank. This valve regulates the flow of gasoline and the passage of air. Do not forget about adjusting the carburetor by changing the volume of air that is supplied to it. You can read more about this operation in the instructions that came with your new chainsaw.

The carburetor of a Stihl chainsaw, without disassembling it, can be adjusted only by the number of revolutions produced at idle. It is impossible to increase or decrease the fuel supply in various modes. Manufacturers have limited access to this adjustment by removing special screws. If malfunctions are detected in this system, it is possible, with experience, to increase the gap between the needle valve and the wall. The saw does not start. The solution is the same as in the previous paragraph.

The tool began to consume more fuel, while its power decreased significantly. Gasoline consumption and power are subjective concepts. To accurately determine these indicators, you cannot do without visiting special companies that specialize in this instrument.

Well, if these two indicators are visible, then follow these steps:

Check to see if the chain is dull. A dull chain has a lower efficiency, and therefore the saw consumes more fuel.

Inspect the fuel tank. It may have developed minor mechanical damage, through which gasoline is leaking out unnoticed.

Carefully inspect the muffler.

Clean the cooling system and exhaust system.

The unit stalls immediately after operation or warming up. Experts call it hot.

Here are the most common reasons:

• Lack of air entering the carburetor. Replace the inlet and outlet valves.
• Cooling system failure (overheating). It is possible that foreign objects have gotten into the cold air pipes and will need to be removed.
• The chainsaw stalls when changing position. This only applies to tilting to the side; in the vertical state, the saw functions normally. This problem applies even to working chainsaws, because during development the designers made a small mistake. The fuel system of the Stihl
  180 has a special design in which, on its side, fuel cannot escape from the tank. Sometimes the problem lies in a clogged fuel pump.

The disassembly procedure, as well as setting up the carburetor of the Stihl 180 chainsaw: In order to carry out high-quality repairs of the carburetor, you will need to remove it. This is not difficult to do, but you need to be extremely careful. To begin with, let's prepare the workplace: install lighting, lay out all the necessary tools. Understand that the carburetor is the main unit of the saw, where the flow of fuel and gasoline intersect. For stable operation they must be cleared of foreign debris.

Therefore, before the main work, you need to do the following:

• Remove and clean the muffler.
• Make sure there are no problems with fuel supply and combustion.
• Check the serviceability of the air and cooling filters.

When using other brands of motor oil, the concentration is different - 1:25. It is not recommended to store the fuel mixture for more than 2-3 months due to oxidation and loss of properties.

Operating instructions for the Shtil FS55 lawn mower

STIHL FS55 operation

Advantages and disadvantages of the FS55 model

The big advantage of the Shtil FS55 lawn mower is its operational reliability, high performance, and ability to perform significant volumes of work. Running in the scythe is simple - just do not overload the engine during the first 2-3 refills of the fuel tank. Subsequently, after 5-15 full refills, you can reach full power.

The disadvantages of the Shtil petrol trimmer include some problems with starting.

To avoid this, you should always check that the fuel tank is full and carefully read the step-by-step factory recommendations for proper starting.

It is important to take into account the specific settings when working at different altitudes above sea level - in mountainous and flat areas, since the degree of enrichment of the combustible mixture may be affected due to different degrees of oxygen saturation of the air.

How to change the coil in a Shtil FS55 brush cutter to a knife

Quickly starting a lawn mower: tips

So, in order:

• Place the tool on its side so that the air filter is at the top. With this arrangement of the chainsaw, the fuel mixture reaches exactly the bottom of the carburetor. The engine will start on the first try if you remove the air filter before starting and pour a few drops of the mixture into the carburetor, then install the dismantled parts in place. The method has been tested in practice.
• If the first tip does not work, then most likely the problem is in the spark plug. In this case, unscrew the spark plug and check its functionality, and also dry the combustion chamber. Replace a spark plug that shows no signs of life with a new one.
• If the spark plug is in good condition, the filters are clean and the fuel mixture is fresh, then you can use the universal method of starting the engine. Close the carburetor choke and pull the starter handle once. Then open the throttle and pull the starter 2-3 more times. Repeat the procedure three to five times. The engine will definitely start.

Some people pull the handle so hard that they have to repair the lawnmower starter with their own hands. This is only possible if the cable breaks or the cable handle breaks. In other cases, it is recommended to replace the starter. This unit is sold assembled.

Specifications

The Stihl FS 55 trimmer is an excellent solution for lawn care. The engine power of this unit is 1 liter. pp., which is optimal for domestic use. In one pass you can cut grass up to 120 mm wide. It is noteworthy that the design has a special system that allows you to care for the grass even along fences, in narrow areas and around flower beds.

The engine capacity is 0.33 liters, which is enough for half an hour of work. The Stihl FS 55 trimmer kit comes with a blade, a protective cover and a trimmer head. This also includes a two-shoulder strap, which simplifies use. As for the protective casing, it acts as a reliable barrier for the fishing line and knife.

Maintenance and repair instructions

From time to time, depending on the intensity of use of the unit, a comprehensive inspection and technical restoration of the structure should be carried out. First of all, the condition of the supporting rod is assessed. In case of serious deformations, it will need to be replaced or corrected in a mechanic shop using a special bending machine. Periodic sharpening and straightening of cutting elements are also performed on boring and milling machines. Damaged discs and blades should be completely replaced. The following spare parts for Stihl lawn mowers can be installed independently: reel, mowing head, cutting elements, handle, protective cover. Moreover, the replacement and installation of functional organs and structural parts are carried out not only in situations of breakdown or cleaning. Having several options for cutting equipment or holders, for example, you can create trimmer configurations with different processing capabilities.

Issues of cost, subtleties of selection and operation

Prices for Shtil petrol trimmers range from 5,500-8,500 rubles for light class devices to 19,500-20,000 rubles for powerful professional models. Their cost, of course, is much higher compared to cheap Chinese lawn mowers.

However, the build quality provided by the manufacturer, a 1-year warranty, and a developed network of dealerships make purchasing a mower from a German brand a much more profitable investment.

Due to the fairly high cost, if repairs are necessary, it is more advisable to purchase the necessary spare parts than to buy a new lawn mower.

When choosing a Shtil manual petrol trimmer, it is important to take into account the characteristics of the landscape for which the equipment is purchased. This includes the area of ​​the territory, as well as its relief

When purchasing a mower with a curved or telescopic bar, you must remember that most often units with an element of this particular shape become unusable. According to expert reviews, the straight rods of the Stihl petrol trimmer are more durable and reliable.

Find out which industries use motor pumps for heavily contaminated water, and whether it is possible to do without this type of equipment.

In the following article you can read the operating instructions for the Zhuk garden sprayer.

We have prepared for you up-to-date information https://spez-tech.com/tehnika/selhoz/pritsepyi-i-polupritsepyi/dlya-chego-nuzhna-proparka-avtotsistern-i-kak-ona-proizvoditsya.html about steaming tank trucks.

It is extremely irrational to buy a powerful professional model of a brush cutter for processing a tiny lawn in front of the house.

It is also important to correlate your physical capabilities with the weight of the purchased device and the length of the rod

Since working with a trimmer does take some time, it would be unwise to buy a model that is too heavy.

The manufacturer strongly advises taking breaks from operation to avoid overheating of the engine and to extend the life of the device. So, for light-class trimmers, every 20 minutes of work you should take a break for the same amount of time.

For professional units, a working cycle of 50 minutes should be interspersed with a 10-minute break.

It is also considered necessary to drain the remaining fuel from the tank when a long period of inactivity is expected. Gasoline evaporates, and the oil, which coats the internal parts of the engine with a thin film, leads to damage to its mechanisms.

By purchasing Stihl gasoline trimmers, the consumer, trusting a world-famous brand in the field of production of household and professional appliances, is guaranteed to become the owner of high-quality equipment.

Trimmers from this German manufacturer are a reliable and win-win investment in an efficient and uninterrupted workflow. With equipment of this class, caring for green spaces will no longer be a labor-intensive task.

In the following video, we are invited to watch instructions on the correct use of the Shtil petrol trimmer:

https://www.youtube.com/watch?v=xMgx4VcKjIM

Additional operating recommendations

At the next stage, it is necessary to restart the engine using a cable. With your right hand, pull the handle until you feel a stop. Then you need to pull the starting cable firmly and sharply. If there is an ergo-start device, then the cable must be pulled as smoothly as possible, while ensuring constant force.

Do not pull the cable all the way. If you will use the Stihl FS 55 trimmer, you must read the operating instructions for this equipment. From it you can find out that the next step before starting is to open the air damper. To do this you need to use the drive lever.

Petrol mower device

You should be familiar with the design of the Shtil FS 55 lawn mower if you plan to operate the equipment, much less carry out its repair. The internal combustion engine in this unit is almost the same as in a chainsaw. However, the latter tire is fixed to the engine gearbox with a long tubular rod. Inside there is a shaft that transmits torque from the motor to the working tool. This design is suspended on a belt that is thrown over the shoulder. This allows you to keep the tool suspended, which is important for the sensitive weight of the chainsaw.

A handle is fixed to the rod of the unit; it can be used to move the end of the rod with the working tool. The petrol mower "Stil FS 55", the repair instructions for which are presented in the article, has a protective shield on the human side in the form of a casing, which prevents injuries during operation. The instrument itself is a round drum with a thick fishing line coming out of holes on both sides of it. When the drum spins, the line is pulled under the influence of centrifugal force and hits the grass, cutting it.

The petrol mower “Stil FS 55”, the technical characteristics of which will be presented to your attention below, has a fast-wearing nylon line. It is periodically updated by unwinding the coil, which is located inside the drum.

Adjusting the carburetor of the Stihl FS 38 brush cutter

Immediately before you start setting up the carburetor of the Stihl trimmer, you will need to eliminate all malfunctions of the model. The engine and other components of the brush cutter must be in full working order. You will also need to clean or replace the felt air filter. To do this, you need to remove the element from its standard housing, wash it with clean gasoline and install it back in place.

The further procedure for adjusting the Stihl FS 38 carburetor is as follows:

1. First, the standard bolt L, which is responsible for adjusting the engine speed in idle mode, will need to be turned clockwise until it stops, and then turned 1.5 turns in the opposite direction;
2. Then you need to start the trimmer engine and give it time to warm up;
3. As soon as the engine cylinder warms up, you will need to press the gas trigger several times. If, after reducing the number of revolutions, the mowing head and line continue to rotate, then you need to start turning the LA bolt one by one until the cutting head stops.

After this, you should check the operation of the Stihl trimmer in different modes. If the carburetor setting is done correctly, the lawnmower motor will quickly gain speed when you press the gas trigger, and just as quickly lose it when you release it.

Signs of imbalance

The carburetor must be debugged during the manufacture of the device. As a rule, owners learn about the need to adjust the fuel supply with their own hands only after quite serious breakdowns, during the process of correcting which the module was removed and, for example, cleaned.

Signs of a settings failure include the following:

Do-it-yourself trimmer carburetor adjustment

Setting up the module is not a repair and replacement of spare parts is not required. In this case, the lawnmower carburetor repair kit will not be needed.

There are three screws for debugging:

• L – is regulated first, since it is responsible for fuel supply at low speeds;
• H – it is responsible for the supply of gasoline at high speeds, as well as fuel consumption and temperature;
• T – it is used to debug the idle speed.

There are options, as a rule, this is the carburetor of a Chinese lawn mower, when for debugging there is only one screw left on the body - for adjusting the idle speed. This does not mean that the module is configured automatically - it means that even such a type of repair as debugging will be difficult. The photo shows the adjustment of the carburetor of a Chinese lawn mower.

• The module is configured only when the engine is warm: to do this, the device is first turned on for 10 minutes. If the mowing head rotates at idle, then begin debugging immediately: turn screw T counterclockwise until rotation stops.
• The adjustment begins with screw L. The screw is turned to the right and left until a position is found at which the idle speed does not become maximum.
• Then the screw is turned ¼ turn counterclockwise. This will be his working position.
• The idle speed must be adjusted
  by turning counterclockwise to increase the speed and clockwise to decrease it. Its debugging consists in achieving a mode in which a sufficient number of revolutions are made before the mowing head begins to rotate. In this case, the engine must operate stably in different positions.
• The position of screw L is determined last - at maximum speed the trimmer
  should not operate for more than 10 seconds. The throttle opens, the screw is turned clockwise, very slowly, until a decrease in the number of revolutions is heard by ear.
• Then the screw rotates slowly counterclockwise until the motor begins to malfunction. After which the screw is turned back clockwise until the engine starts working normally again.

If there is a tanometer, and if the recommended speed values ​​are indicated in the product data sheet, the correction can be carried out more accurately, focusing not on hearing, but on the readings of the device.

The trimmer carburetor adjustment in the video was done by ear.

Features of operation

Each Stihl lawn mower is designed strictly to perform the intended work, taking into account engine power. The manufacturer categorically does not recommend retrofitting or in any way improving the scythe device. Therefore, before buying a STIHL lawn mower, you need to clearly determine the scope of work ahead.

It is completely inappropriate to purchase a powerful trimmer for periodic mowing of grass on the lawn; light gasoline or electric models of mowers are quite sufficient for this.

During operation it is important:

• Follow the regime: work/rest at intervals of 20 minutes.
• Use high-quality gasoline not lower than AI-92.
• To prepare the fuel mixture, use original STIHL engine oil (50:1).
• When running the engine until 2-3 full fillings of the fuel tank, do not allow operation at maximum load.
• When storing the scythe for the winter or an expected break in operation, in order to avoid engine breakdowns, be sure to drain the remaining gasoline from the fuel tank.
• To ensure stable operation, systematically check the condition of the fuel filter - clean it or replace it with a new one.
• To prevent serious problems, it is necessary to avoid clogging the air filter.
• Follow safety requirements when operating STIHL lawn mowers.

Features of using electric models

The main advantage of electric mowers is the presence of an electric motor, so to use the mower you only need to have sockets near the place of work.

More details about safety precautions can be found in the instructions.

The battery of the electric model takes about 200 minutes to charge, and the operating time until completely discharged is 20 minutes when using plastic knives and only 12 minutes with a string.

Rules for using a lawn mower:

• Make sure that the trimmer frequency matches the mains voltage;
• Make sure the cable, plug and extension cord are intact;
• Do not touch current-conducting elements with wet hands;
• Only use a suitable extension cord.

Petrol mower Stihl FS 55 – design features of the model
