How to increase the power of benzocosyles is good. The design of a home -made gas generator

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 nozzle to use for mowing grass with a benzoca

The design of the gas station uses two types of cutting nozzles or milling. These are coils with fishing line, as well as steel or plastic disks. What is better to choose for work with a gas engineer. The site presents information on how to choose discs and fishing line for a trimmer for trimmers, as well as their types and design features. Briefly consider what types of cutting mills should be used on trimmers and benzocoses.

• To prick soft grass, a fishing line for a trimmer is used, which is wound on a drum or coil. Lines for a trimmer, unlike metal disks, is used where the grass grows next to trees, houses, fences and other obstacles. The fishing line for a trimmer allows you to produce high.quality grass mowing near the obstacles, while without violating the design of the tool
• Metal knives. have 2, 3, 4 or more cutting parts, through which the grip of rough grass and thickets are carried out. Practice shows that the thicker the sprayed thickets, the more blades should have a mill
• Metal discs with small teeth in an amount of 40-80 pieces-designed to prickly prickly vegetation. It can be rough grass, weeds, thick thickets and even small trees. The larger the number of teeth on the cutting nozzle, the higher the effectiveness of the tool in question
• Plastic discs. are used mainly on electritrimers or batteries

The choice of cutting milling cutters depends on the location of the tool. If it is planned to work in the personal territory, then a fishing line for a trimmer is selected, and for injection of grass in the field or steppe, discs with 3-4 blades or more, as well as disks with small teeth are used.

It is interesting! In most cases, cutters are not equipped with an instrument, so the buyer can independently decide what he needs. a fishing line for a trimmer or a steel disk.

How to fix a disk or a fishing line for a trimmer on a trimmer

The cutting mill is attached to the executive organ. The mounting location is called a gearbox. It is not difficult to cope with the task of installing a disk or coil. The principle of consolidating cutting discs on the trimmer is as follows:

• The figured washer is originally fixed by using a hexagonal key
• On the shaft set the disk
• Then install the upper washer, and then tighten it by means of the fastener
• It is necessary to rotate the nut through a special end key, which is usually equipped with each tool
• The rotation of the nut is carried out in the direction counterclockwise
• When rotating, it is necessary to jam the shaft with a hexagonal key

In the opposite sequence, the disk on the trimmer is removed and replaced. details on how to install a coil with a fishing line on a lawn mower is described in this material.

How to set up a lawn mower carburetor to work better, and fuel eats less

Get one most read article by mail once a day. Join us in and

Nowadays, the word “carburetor” is familiar mainly only to those who have yet found cars with the corresponding engines in their memory. At the same time, carburetor power units are universally used in a variety of agricultural machinery for giving. Just get into an important detail with a screwdriver, few will dare to imagine it with a sort of “sacred cow”, which is better not even to approach. And in vain.

In fact, a carburetor is a fairly simple device. The same can be said about its configuration. There is nothing out of place in this matter, especially when it comes to garden technology. Equipment adjustment options, in fact, only two: setting idle revolutions and setting up a mixture of gasoline and air. Both calibrations are carried out by carrying out manipulations with one of two bolts. Most often, the setting of the supplied mixture is made using a thick yellow screw, and the idle calibration is sold using a thin white screw.

Before performing any manipulations with a carburetor of any garden tool, the engine first needs to be turned on for several minutes and warm up. In this case, the damper regulator must be put into a position corresponding to the work regime. Immediately after warming up the mechanism, the screw that is responsible for the quality of the air-banding mixture is twisted so that the idle speed of the tool begins to fail. The motor may stall.

Next, the screw is unscrewed from the reach of the half-turn in the opposite direction. We give full gas, if the tool engine did not stall and did not begin to zoopet, then everything was done correctly. If nothing has changed, then the mixture screw is unscrewed by another quarter turnover, behind this is again the check and so on until the victorious end. We can check the result of prolonged gas without fail. the lack of cotton, zabulak, and extraneous noise will confirm success.

The next thing that can be done to set up a trimmer for grass is to set a suitable idle parameter. The principle of adjustment here is exactly the same, only now we work with a thin white screw. On a heated engine, we tighten it to a state of zabovki of the unit when pressed on the gas, after which we begin to gradually release. First to the turnover, then half, then a quarter. until the tool starts working normally and without obvious interruptions.

The correct calibration of the revolution screw will reduce the amount of fuel consumed, and the competently set the mixture screw. increase the capacity of the tool. By the way, the details about the setting are contained in the technical leadership, which was supposed to be included with the acquired garden tool.

Winter is no longer around the corner, and therefore it should be read about what a real cleaning mechanization is: how to make a snowball player from a trimmer for grass.

The selection of elements for a gasoline generator

As already mentioned, it is very difficult to carry out mechanical adjustment on your own. Electronic will require alteration of the generator.

Therefore, it makes sense to make a benzogenrator with your own hands according to an inverter scheme, and use a converter from source of uninterrupted power as a converter.

The choice of equipment is influenced by the following factors:

The maximum power of the gasoline generator primarily depends on the engine power. The following devices have such power values ​​and the number of revolutions:

The most simply with your own hands are performed on the generator from the car (rice. below). A typical generator for a passenger car is capable of issuing a voltage of 13 14 V at the output at a load current of 80 100 A. A simple calculation will show that the power of such a generator is no more than 1.4 kW. Large values ​​can be obtained using generators from trucks.

A car generator is well suited for creating a gas generator

Many trucks are equipped with 24 in generators.

The indicated characteristics of the generator have with an average of 5000 rpm, which does not correspond to the normal turnover of the listed engines. To align the values, you can use the belt transmission with different diameters of the pulleys (rice. below). The number of revolutions on the leading and driven pulley is inversely proportional to their diameters. But the transmitted power changes the opposite.

Belt gear with different pulleys

The gasoline generator, made on the engine from the chainsaw or lawn mower, needs lower gear to reduce the number of revolutions by the generator shaft of approximately half. The power transmitted by the engine to the pulp of the generator will also increase in terms of double. In the case of using the engine from the walk.behind tractor, the transmission is required to increase.

It is impractical to use gearboxes in a home.made structure, since the complexity of the work on the manufacture of the gearbox is high. Poorly executed gearbox greatly reduces the efficiency of installation and serves as source of additional noise.

The following necessary device is an inverter voltage converter (rice. below).

Inverter converter. source of uninterrupted nutrition

Speaking about the capacities of the engine and the generator, the power of the converter was not mentioned. It is she who can become a weak place of a home.made gasoline generator. Powerful converters have a fairly high cost. Alteration of a low.power converter can only be for those who are very well versed in radio electronics and know the principle of operation of the device. The minimum alteration is to replace the elements of the rectifier (power diodes and filter condensers), key transistors and output transformer.

The battery of the uninterrupted power supply is undesirable to turn off. It is used to load the generator and is designed to smooth out the surplus surges at its output. Most automobile generators with low load give an inflated voltage.

An example of calculating a gasoline generator

In each individual case, it is necessary to calculate a home.made gas generator based on the available details. An example is the calculation for the engine from the chainsaw and the common generator from the car VAZ 2110 5102.3771.

The engine has a power of 2 kW at 10,000 rpm. Generator 5102.3771 issues voltage 14 in current up to 80 and at 5000 rpm. The capacity of the generator is 1120 W.

To obtain the required number of revolutions on the shaft of the generator, a lowering transmission with a gear ratio of 1: 2 is required. If you leave a standard pulley with a diameter of 51 mm on the generator shaft, then a pulley with a diameter of 25 mm will need to be installed on the engine shaft. This is very little. The transmission belt will be greatly curved and will experience heavy loads. It is better if the generator’s pulley is installed on the engine, and put a pulley with a diameter of 100 mm in its place. The pulley can be machined on a turning machine made of duralumin.

During the engine operation at nominal speeds of 10,000 rpm, the generator rotor will rotate with a frequency of 5000 rpm, which is the best value. In order to fully use the generator power supply, a converter with a capacity of at least 1 is required.5 kW.

Buscores-highs from the lawn mower-the advantages of the tool

Very often summer residents are faced with the need to cut trees. Using a trimmer for grass and a bitch’s nozzle, you will not need to use a stepladder or climb a tree. Having fixed the device on the rod of the tool, you can cut the branches located at a height of up to 3-4 meters (depending on the length of the bar and the presence of the extension cord).

The nozzle is also called a high.speed, which is associated with its main purpose. pruning of highly growing branches. The device is a chain tire, like on a chainsaw. The design provides a tank for oil designed to lubricate the circuit. The nozzle is attached to the rod of motorcycles, after which the tool is immediately ready for work.

When choosing a device for a trimmer for grass, you should buy models of a similar tool of the manufacturer, which will eliminate the likelihood of the impossibility of combining devices. When choosing such a device, special attention is paid to the diameter of the bar and the number of drive shaft slots.

When operating the device, it is very important to observe safety precautions. Run the engine with the installed nozzle directly next to the tree, which is planned to be cut. You can order a device for motorcycles on the popular website Aliexpress.

The lack of the device is manifested when operating. To cut down thin branches, it is necessary to maintain them, otherwise the vibrations are not an even cut.

trimmer for grass as garden scissors for hedges

You can use the lawn mower to cut the hedge. For this, a special nozzle with an oblong cutting part and moving knives is used. Knives are driven from the shaft of the internal combustion engine motor. The design of the nozzle garden scissors is presented in the photo below.

A feature of these devices is the ability to change the angle of inclination of the cutting part. To do this, you do not need to turn the engine, since the design provides for a special adjusting lever. The equipment is suitable not only for gasoline trimmers, but also of electric.

Manufacturers produce devices with a length of the working part of 55 cm, which allows you to choose the right option depending on the size of the trimmed shrubs. This equipment does not have practical disadvantages.

Benzotrimmer loves cleanliness. It is necessary to monitor the purity of the air filter and fuel. It is better to defend gasoline bought at a gas station for 2 days and pass through the simplest filter. a piece of bike matter.

We check the electrical equipment as follows:

We unscrew the candle, examine the gap between the electrodes. We set the right gap between the electrodes can be a “grandfather” way. We take a blade from a razor, scraps in half and insert a home.made probe between the electrodes. If the blades enter tightly, then the gap is perfect.

We put on a candle cap of a high.voltage wire and lean the candle against the metal surface of the engine. Twist several times by the starter. If the spark beats well at one point, then the gap is adjusted correctly. If not, the spark is weak or “wanders”, then it is necessary to re.adjust the gap between the electrodes.

Also, the ignition coil can be broken in electrical equipment. In this case, the lawn mower will not start or start and works with interruptions, and then stalls, or “hot” does not start at all.

You can check the serviceability of the coil in the same way as when checking the spark: we unscrew the candle, lean it against the trimmer body for the grass. If there is no spark with a jerk of the starter, or it appears through time. you need to change the coil.

The result of proper run.in a gasoline trimmer for grass

After you have been running the lawn mower by the instructions, as a result, we get a tool ready to work. Of course, it is best not only to read the stages, but also to see the crowding on the video from specialists. The result of the correct actions will be obtained:

• trouble.free operation of the benzo tool for a long time;
• high.quality start of the device and stability of the submitted power;
• lack of unforeseen repairs of a trimmer for grass after high.quality pounding;
• Lack of overheating.

In this regard, the primary processing of the Chinese braid for grass is an integral part of the quality work of the device that can work flawlessly using benzos knives or cutting fishing lines of different diameters when processing territories available in the special store “Spit for grass”.

Mow security

What are the precautions when working with a trimmer? There are several simple and understandable points, after which you can avoid dangerous situations and minimize the likelihood of injuries:

• Do not use a trimmer for grass in raw and wet weather (especially an electric trimmer for grass);
• Dress in front of a boosting body so as not to damage the skin with pieces of grass stems flying from a disk or fishing line at high speed;
• Keep a distance of 15 meters from other people and pay attention to the signs that others can give;
• With the help of headphones or beryushi;

• Use an electric trimmer for grass to make sure that the wire from the extension cord is always behind;
• Put on tightly rubber boots that are easily washed after work;
• With the help of gloves and protective glasses, to avoid small stones in the eyes and respiratory tract;
• In case of injury, consult a doctor immediately.

In addition, do not forget to look back, suddenly you will encounter an obstacle in front or side. When diving a bar with a blade into thick thickets of grass, keep in mind that there can be stone, stump or berries (for example, strawberries). Working with a trimmer requires discipline and attention, but as soon as you understand simple rules, this will become familiar, understandable and will bring only positive emotions from the results.

How to adjust the carburetor of the lawn mower with your own hands

Adjustment

• Run the motor. When it is launched on the XX, knives should not rotate, but if the opposite occurs, then we reduce the speed of the idle.
• We adjust the screw l. He is responsible for the mixture at low speeds. First, scroll to the stop clockwise, then unscrewed 90 degrees against the sentry. If you find failures, we repeat this action, weakening it for 1/8 part, that is, 45 degrees.
• Adjust the La screw, more frequent name. t. With an increase in speed XX, more air is added to the mixture. Power is lost. But if there is not enough air, fuel is burned worse. We unscrew the screw so that it works perfectly at low speeds, while the knives should not rotate. In the process of setting, you need to feel momentum, it should work stably on XX.
• Adjust the screw h, which sets up the mixture at high speeds. To identify their maximum quantity, we use a tachometer. Upon reaching the largest number of engine speed, we unscrew the screw to the left by 180 degrees, the adjustment on this ended.

Sometimes only the correct setup and the use of the device reveals its entire potential. No need to neglect it and conduct as necessary.

The reasons that the trimmer for the grass does not develop momentum

External signs

The reasons are that the lawn mower is not gaining momentum, vary. Some are not even related to the breakdown of the device, for example:

• Getting on the filter of dirt or dust.
• Pouring low.quality fuel mixture.
• Using poor gasoline or overdue oil.
• Pollution of the engine components, which does not allow the instrument to gain momentum.

In the case of pollution on the carburetor, he sees a lot of soot. It is the reason that the trimmer for the grass does not gain momentum.

Internal problems that the gasoline trimmer for grass does not develop momentum

Technical malfunctions are manifested in both old and new devices. Do not be surprised. even a new trimmer engine for grass may not develop revolutions. Check the ignition system and supply of the mixture for serviceability:

• Когда коса для травы заводится и тормозит или даже не заводится, то проблема может быть в свече. A dark carrion appears on it. a sign of poor.quality gasoline and poor carburetor work.
• A flooded fuel hose is another problem due to which STIHL is not gaining momentum.
• With prolonged work without cleaning parts, a muffler can clog. Check the system for the presence of dark particles and clean the pipe, then the motor will start and start working as a new.

If the problem is in the motor itself and you do not know what else to do, be sure to take it to any master. You are unlikely to do something inside the motor, all the more right. And you will always have time to harm the device.

Serving parts of a benzotrimmer to prevent a problem

In order not to in vain to disassemble the motokos, it is worth diagnosing each zone separately. the problem can be in both one and several parts. Where to look and what to check.

Carburetor

One of the main nodes of the correct work of the trimmer for grass. So that the part functions as necessary, adhere to the conditions:

• Each month to remove and clean the part;
• Configure idle, according to the manufacturer’s instructions;
• If you yourself cannot set up. take the master.

One of the popular reasons for the breakdown of the motor. the carburetor cable is not pulled. To eliminate the problem, you need to disassemble the carburetor first, clean it, and only then tighten the cable. Just do not overdo it so that it does not pull like a string.

It is worth checking additionally: an intake needle, a membrane, a setting lever, a damper and other components of a carburetor. They may also have problems that interfere with the correct work of motorcycles.

Spark plug

Even if you don’t know what a normally working candle should look like, just remove it, dry it and clean it with sandpaper. Return the part to the place.

You can also check the distance on the main part. Maximum. 1 mm gap between parts of the fabric.

If the candle is too black, then there is no point in cleaning it. just buy a new one and install it on the motor. Then the whole system will work with new forces.

Filtering system

The blocking of an air filter can sometimes affect work even more than problems with the candle. To check if it is a problem. run the engine with the filter removed. If you started, rinse the filtration sponge in gasoline or other moisture. And you can buy a new one. this will only benefit your trimmer.

The clogged filters do not let the fuel mixture into the motor, so it stalls or does not start. The lack of gasoline can be fixed with banal cleaning: both a filter under the lid and the filter of the fuel hose (located inside the plastic tank for fuel).

Motor malfunctions

Internal combustion engine. the basis of the operation of the gasoline apparatus. What may be wrong with him if the motor does not gain power:

• The fuel mixture is incorrectly prepared, or its expiration date has long been released;
• The piston rings broke;
• Cylinder or piston in scratches and cracks;
• The device is used without breaks.

With the repair of the motor should be careful. This is because if you incorrect all the details, then you can stay like without a trimmer for grass, and also with injuries. Trust the case to a specialist!
