• The fuel supply system is certainly narrowed by the mixer to accelerate the flow.
• Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already small. Thanks to the pressure drop, fuel seeps through a jickler.
• Acceleration of the air flow contributes to the transfer of fuel (gasoline) and its spray. Ultimately, a fuel mixture of the desired proportion or density appears.
• The air-fuel mixture seeps into the cylinder of the motor through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. The more extensive the damper is open, the greater the fuel consumption and power.

The main problems and malfunctions of the carburetor.

Mesh filter. There are only two problems with this element more often:

In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If dirt just accumulated on it, then flushing in gasoline or purging will help.

With visible damage on the mesh filter, you must definitely put a new. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).

Chips on the choice

In accordance with the current statistics, it is the gasoline models of mowers that are most in demand. This is largely due to their mobility and functionality. However, when choosing a specific model of technology, it is necessary to take into account a number of other parameters. In such situations, it will be useful to compare motorcycles with other types of trimmers.

Electric devices are connected to a household network with a voltage of 220 V. Such machines do not pollute the air due to the lack of exhaust gases. No less important points will be the minimum noise level and relatively small weight. At the same time, the processed area is significantly limited.

The battery models today are the least common trimmers for grass for grass. The electric engine of such mowers does not feed from the network, but from the battery, which provides maximum mobility. However, the operating time of the equipment is limited by the battery charge and is an average of 35-45 minutes. Another important point is the relatively high cost of battery models.

When choosing a specific model of a gasoline trimmer for grass, it is necessary to take into account its technical characteristics. So, low.power devices are equipped with coils with a fishing line. On more reserved and powerful models, knives and cutters can be used as cutting elements.

Another important factor is the operational conditions. Do not forget about the cost of mowers.

The device of the carburetor of the lawn mower

The base of the carburetor of the lawn mower. the duralumin case. It contains a diffuser (a hole with internal contours). Air is pumped through this hole. The speed of oxygen (air) is dependent on the cross.sectional (passage opening) of the diffuser.

The device of the lawn mower

You should know the device of the Stihl FS 55 lawn mower if you plan to operate the equipment, and even more so to repair it. The internal combustion engine in this unit is almost the same as in the chainsaw. However, the last tire was recorded to the engine gearbox with a long tubular rod. There is a shaft inside, which transmits a torque from the motor to a working tool. This design is suspended on a belt that throws over the shoulder. This allows you to hold the tool on weight, which is important with a sensitive mass of the chainsaw.

The handle is fixed to the unit rod, using it you can move the end of the bar with the working tool. Stihl FS 55 lawn mower, which is presented in the article, from the person’s side, the person has a protective shield in the form of a casing, which excludes injuries during operation. The tool itself is a round drum, on both sides of which a thick fishing line for a trimmer comes out of the holes. When the drum is spinning, the trimmer fishing line is pulled under the influence of centrifugal force and hit the grass, cutting it off.

Stihl FS 55 lawn mower, the technical characteristics of which will be presented to your attention below, has a fast.significant nylon fishing line for a trimmer. It is periodically updated by unwinding the coil, which is located inside the drum.

How to set a ignition on a trimmer

Often, owners of gasoline cos are faced with the fact that the ignition does not work on their equipment. In most cases, the problem is really with this knot. To fix this, you need to adjust the ignition to a trimmer for grass. But at the same time, it is not uncommon for the ignition coil to be in good condition, and a breakdown must be sought elsewhere. The ignition system is constructed equally on four.stroke and two.stroke internal combustion engines, so the elimination of the device malfunctions is performed similarly. In addition, the technologies of various brands have an almost identical design of this most important component of the tool, which means the regulation process will be the same as for trimmers a union or foreman, and for Huter, or for samples of other brands.

Any STIHL lawn mower is designed strictly for the work provided for in the engine power. The manufacturer categorically does not advise without the help of others to receive or to improve the device of braids for grass. Therefore, before taking the Stihl law mower, you need to correctly determine with the upcoming front of the work.

It is completely inappropriate to receive a powerful trimmer for grass for repeating mowing of grass in the clearing, for this fully quite light gasoline or electronic models of mowers.

Features of adjustment on different models of trimmers

The ignition system works similarly on various brands of equipment, so the setting process will look the same. Differences, if any, are insignificant. They are mainly associated with the disassembly of equipment. For example, removing the cover from the engine on various trimmers for grass is made with some differences. So, on Patriot devices, you first need to unscrew the bolts and disconnect the air filter housing with a slit screwdriver. After that, the plastic cover will be very easy to remove. A detailed diagram and a trimmer for grass of a particular model are usually shown in the instrument operation instructions.

So, you can adjust the ignition of a gasoline trimmer for the grass with your own hands. This process is not difficult if you know right

procedure. But first, the possible malfunctions of other components and details, for example, spark plugs or a magnet, should be excluded, which may cause the absence of a shield for the engine of shieldcorr. However, analyzing the equipment of various brands, you need to take into account the possible differences in design, which are described in detail in the user manual.

Typical malfunctions

Before proceeding with the ignition of a trimmer for grass, you need to cut off other probable causes of damage and make sure that the problem is really in this device. For this, it is necessary to carry out a number of actions in the following sequence:

• Inspect the ignition coil body for damage and defects;
• Make sure that there are no pollution on all nodes and elements that conduct current;
• Check the integrity and isolation of the electrical wiring, contacts, fastening strength, the presence of rust at the joints;
• Inspect the lid of the candle, since it regularly breaks away from the high.voltage wire, and they try to restore it manually, and any unreliable connection reduces the power of the electric arc of the candle;
• Check the light of the ignition, since the quality of modern gasoline very quickly destroys this part, but there is another possible problem of a wet candle;
• Make sure the circuit breaker works.

By excluding all possible malfunctions, you can proceed to regulate the ignition of the coil.

STIHL FS 250

Advantages: advantages: 1) the power necessary for comfortable work; 2) reliability in work; 3) when using a primer and fuel compensator, it starts perfectly; 4) the presence of a dialing shoulder belt included; 5) price motorcycles.

Disadvantages: Disadvantages: 1) increased fuel consumption (relatively less powerful motorcycles) 07-08 liters per hour of the gas mixture when the lawn grass is spent; 2) a little noisy (relatively less powerful motorcycle), the level of sound power, with a plastic instrument of DB (A) 2. 114, the level of sound pressure with a plastic instrument dB (a) 2. 99; 3) a little heavy 6.3 kg. (heavier on average by 800g. other less powerful motos) 4) the absence in the kit: a) headphones; b) mowing head. 5) the gas tank cover is not the same as in other trimmers, the German assembly (the lid opened without auxiliary tools is a very convenient thing). assembly Made in China.

Commentary: All accurate characteristics, not only this, but also other cops of motorcycle can be found on the official sites of distributors and manufacturers, for comparison, if you are going to purchase a motorcycle. Sensations during operation, this is a subjective factor. I use Stihl FS 250 for mowing various kinds of herbs on a area of ​​about 40 acres for the 2nd year already. In the manufacture of a gas mixture, I use, AI-95 gasoline and mineral oil for two-stroke engines STIHL HP (red) in a proportion of 1:45. But the next season I plan to use the synthetic oil HP Ultra (green). I work in a sparing mode, not for “full gas (the benefit of the engine allows)“, but only “1/3”, “1/2” for a short time on “1” (full gas). Since at full gas in hot weather with prolonged use for 2-4 hours, you can overheat the engine, and fuel consumption and the noise from the engine can also significantly increase. During ownership and use (2 years), breakdowns and difficulties in operating a trimmer for grass did not occur. Each season, when servicing braids for grass, I change the air, fuel filter, light of the ignition, as well as add branded grease to the gearbox. Elementary cleaning, washing. I use Fixcut-a simple 2-string mowing head, it is a little not convenient, since you need to constantly update the dull end of the string (turn over), for effective mowing of the grass, which is not possible on this head, therefore I recently acquired an automatic mowing head, installed a knife on the casing cutter. Metal knives for motorcycles STIHL 2Z 230 mm (two lobed) and STIHL 3Z 250 mm (three lobed) I do not use it yet, I cope with strings of the square section of different diameters. I did not have trimmers of other brands, this is the first one, there is nothing to compare with, but probably well.known brands, except the cheapest, will work about the same.

Advantages and disadvantages

The main breakdowns are associated with violation of the rules for the installation and operation of mowing heads, knives and discs. Therefore, with the aim of safety and safety of equipment, it is necessary to strictly observe precautions when installing cutting tools and protective devices.

These are most likely problems with the carburetor. How much to your trimmer? If the new one is a warranty, if the old man, then there is another option that the seals are covered, but this is a very rare case. There are also two common diseases. Over the years, either a silencer or the exhaust window of the cylinder is clogged, as a rule, an experienced master is determined by the sound of the motor when the engine is determined. And the second disease recently is the ignition coils on FS38 and FS55, everything is the same there. Also check the fuel hoses, whether they crackled (have not yet seen this on these trimmers, but still. ). I do not advise you to regulate the screw indicated by the letter l, and h, too. The first is the adjustment at low speeds, the second happens from the factory with a plastic limiter, is responsible for maximum speed. If the braid for the grass worked normally, then problems appeared, then first you need to rinse the carburetor, then look at the adjustments, the adjustments themselves are not lost, and the dirt from the carburetor cannot be adjusted. It happens that people will regulate that the sound works fine, but then they repair the motor. In trimmers and chainsaws, in addition to cooling the air from the outside air, the cylinder with ribs is also the concept of internal cooling due to the evaporation of the fuel, and if it is not enough for this, then in half an hour you will ruin the motor. This happens when air sunses through seals or other possible places or with incorrectly adjusting the carburetor (screw L). The maximum revolutions are set along the electronic tachometer and no more than 10,000 on trimmers. You can find out how much maximum speed and standard adjustments can be from the original operating instructions for your tool.
