Why choose the FS 55 brush cutter

If you still don’t know which model of the described equipment to choose, then you should read reviews about the Shtil FS 55 lawn mower. After reading them, you can understand that consumers identify many reasons that made them lean towards the described model. For example, instead of a strap, the manufacturer provided the device with a belt. This allows you to distribute the load from the device across your entire back. Otherwise the weight would be concentrated on only one shoulder. With this placement option, even after very long work there is no back pain.

Buyers also like the bicycle handle, which increases ease of control. When working, your hands will be spread wide apart, so it is easier to control the unit. It is very maneuverable. Buyers like that the handle and belt can be adjusted to suit the operator's needs.

The tool can be easily adjusted for comfortable use. The controls are located on one handle. There is no need to reach anywhere, everything is located under the palm of your hand. The Shtil FS 55 petrol mower, according to consumers, is also convenient because it has a pair of protective covers, one of which is installed for the knife, while the other is for the fishing line. The casing for the latter has a narrowing at the rod.

The trimmer has a head that is clearly visible and allows you to handle tight spots. The escape of stones from under the knife will be prevented thanks to a special casing. This helps protect the operator. Using the existing primer, you can pump fuel into the carburetor. Even after a long period of inactivity, as consumer reviews indicate, the lawn mower is quite easy to start. Engine starting is made easier thanks to a special easy start system. As home craftsmen emphasize, you no longer have to waste energy on pulling the cord for a long time, because for this you will need to make 2 jerks.

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.

Operating Instructions: Safety Precautions

The equipment described above must be used while wearing special clothing and using the equipment. Clothes should not interfere with work. You should choose one that fits well to the body. It is necessary to exclude wide sleeves that could get caught on bushes, wood or moving parts of the unit.

It is important to remove ties and scarves. This also applies to jewelry. Before starting the Shtil FS 55 lawn mower, you must wear protective boots that have rough soles. It is important to use a special protective helmet and glasses that will prevent damage to your vision.

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.

Refueling

The lawn mower runs on gasoline, which is highly flammable. Therefore, do not smoke nearby while refueling. Before refueling, the engine is turned off. Do not carry out such manipulations until the engine has cooled down, as fuel may overflow and begin to pose a fire hazard.

The fuel tank lock must be opened with extreme caution, as excessive pressure may cause fuel to splash. The Shtil FS 55 petrol mower, the operating instructions for which you must study before using the device, is refueled in well-ventilated places. If fuel is spilled, the device should be immediately cleaned of it so that it does not get on clothing, otherwise the latter should be changed immediately.

After refueling is completed, the fuel tank screw lock must be tightened as far as possible. This will reduce the likelihood of it unscrewing due to motor vibration. If this is not provided for, there is a risk of fuel leakage. It is important to pay attention to leaks. If fuel has been spilled, do not start the engine, otherwise there may be a risk of burns.

Repair instructions

The Shtil FS 55 petrol mower, the operating instructions for which is supplied and must be studied by you before starting work, is a high-tech equipment that is not difficult to maintain. You can carry out repairs and adjustments yourself. As for the carburetor, this is a matter of 5 minutes.

The main problems of carburetor malfunction can be breakdowns and blockages. In order to find out the reason, you should unscrew the fuel filter cap and remove the strainer. If dirt has accumulated on it, then blowing or washing in gasoline will help. If you find visible changes on the filter, it should be replaced with a new one.

The fuel supply pipes may also be damaged. Failure to operate the carburetor starter may occur due to gaps. Gasoline or acetone is used for washing. The carburetor can be blown out with compressed air using a convenient repair practice. The exhaust or intake pipeline may become depressurized, as well as the throttle body and those places where the carburetor parts are connected to each other. If you encounter the above-mentioned problem, you can verify it using a soap solution that is applied to the desired area.

Carburetor adjustment

The carburetor for the Shtil FS 55 lawn mower can be adjusted independently. To do this, the filter should be cleaned, following the maintenance rules prescribed in the instructions. The carburetor is adjusted using adjusting screws, there are three of them:

lower;
left;
right.

The latter regulates the fuel mixture for low speeds. You need to find the maximum idle speed. To do this, the right screw is turned in both directions. In order to make adjustments, the screw must be turned counterclockwise a quarter turn.

When adjusting the Shtil FS 55 lawn mower, you must also use the lower screw, which is responsible for adjusting the engine. If you turn it clockwise, you can achieve an increase. Correct idle adjustment is characterized by normal speed of a hot engine, stable operation of a cold motor and a large reserve of revolutions for the trimmer head. The engine continues to operate stably even when changing position.

Adjusting the carburetor of the Shtil FS 55 lawn mower also involves engaging the left screw. It regulates the mixture at high speeds. It is necessary to deal with this screw last, because the adjustment of maximum speed, fuel consumption and temperature, as well as engine power depend on it.

First launch, run-in

All STIHL brush cutters are distinguished by high build quality, so they require minimal grinding in of components and rotating parts and mechanisms. When starting for the first time, give 5 minutes to warm up the engine.

! Prolonged operation or prolonged running-in of the Stihl lawn mower at idle speed is strictly prohibited. This mode for all Stihl lawn mowers with two-stroke, 2-MIX and 4-MIX engines leads to overheating of the device, incomplete combustion of the fuel mixture, increased formation of soot, and is fraught with serious damage and subsequent expensive non-warranty repairs.

The manufacturer recommends that during the first three refills of the fuel tank, load the lawn mower minimally, which is what the break-in process actually consists of. After 5-15 full tank refills, the scythe reaches full power.

Recommendations for holding and guiding the device

The brush cutter must be held securely with both hands. The operator should take a stable position when doing this. You need to grab the handles with both hands. Brush cutters with a round handle are offered for sale; the left hand should be on a hill, and the right hand should be on the working handle. If there is a danger of an accident, the engine must be turned off immediately. The engine should run flawlessly at idle speed. The cutting tool must not rotate after releasing the throttle lever.

The idle speed setting needs to be monitored and adjusted from time to time. If the cutting tool continues to rotate at idle, the unit must be sent for repair. When mowing, you need to pay attention to obstacles in the form of tree roots and stumps. You must work while standing on the ground. Do not use a ladder or elevated work platform.

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:

starts, but the engine immediately stalls - since the engine can only work when a certain amount of gasoline is supplied, if the fuel is too “lean”, that is, the supply channel is blocked, the engine will stop;
too much fuel consumption, a lot of exhaust gases - the result of incomplete combustion of the mixture. In this case, on the contrary, there is too much fuel and the mixture turns out to be excessively dense.

The carburetor of STIHL, Makita, Husqvarna and other lawnmowers is adjusted using adjusting screws. Sometimes the cause of malfunction is a violation of fixation - due to vibration or damage to the protective cap. Such a breakdown can be detected by simply trying to slightly turn the screw: if the fixation is not tight, it is worth checking the setting.

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 will not be needed.

How to independently adjust a carburetor with three adjusting screws: full cycle

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.

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.
