Playing the motor motorcycles. Features of the game of the lawn mower

It should be noted that a gasoline braid for grass is controlled very simply. It is enough to see how other users use this unit to start using it fully. The performance of the main technical functions is intuitive and does not require any difficulties in practice. Correctly driving a gasoline trimmer for grass is also not difficult. over, there is almost no difference between devices of household and professional categories.

The key difference is the type of motor. On technology for professionals, it is more powerful and gives more revolutions. A two.stroke engine is more often used in household models. Four.stroke units are more reliable and give out a greater effort, so they are suitable for special conditions, difficult and overgrown sites.

In addition, we must consider whether there is a cutting device in the supply set.

Presentation preparations

So, let’s start with preparation for work. How to bring the law mower to a state of full readiness for use?

First of all, collect it if it is disassembled. Strong the detachable bar in the latches. Carefully check the fixation of cutting equipment, especially if it is a knife or a saw disk. Gasoline trimmers for grass are usually extremely powerful, and the speed of rotation of cutting equipment in them is simply fantastic. Therefore, a poorly fixed blade, firstly, can injure the employee, and, secondly, causes additional vibration in the tool, which can lead to his breakdown.

Gasoline models are most often equipped with a two.stroke engine, so they need to prepare the fuel mixture. What is its purpose? Since in such engines there is no crankcase and a separate system for oil lubricant, this role is played directly by the combustible mixture.

It is prepared in certain proportions and for one dressing. Immediately dilute several liters, with a “margin”, should not be, since the composition should always be fresh.

Choosing a trimmer for the grass for giving. My experience

The coil of my “Alpina” exploded right under my feet when I mowed weeds by the fence. When searching for this spare part, I came across options for 1500-1800 (it was three years ago). Well, very expensive, as it seemed to me. Then a colleague told me that he had recently bought a powerful trimmer for Baikal 4500 grass for only 4900 (. The price for everything is very tempting.

I immediately called this company, but the manager upset me, saying that the same “Baikal” is no longer. However, he offered me a lawn mower of the Chinese Safun brand with a capacity of 2.5 kW for 4000. Getting stuck, in a word. And besides, I was pleased to buy a mitch for the price of two coils for a trimmer for Alpina grass. Among other things, I really wanted to check how long the cheap Chinese model will work and how much the engine power corresponds to the description in the description.

A trimmer for the grass that my colleague acquired, with a weight of slightly more than 5 kg and the engine volume 52 cm³ has a declared power of 5.5 kW. Just some kind of miracle! In the kit. two knives and a reel with a fishing line. The recommended fishing thickness is 2.4 mm, which seemed strange to me, because the engine power is twice as much as that of the Chinese Safun offered to me, and the recommended fishing line for a trimmer is thinner. “Baikal” we slightly shared the weeds in the far corner of the site. He cuts the grass well, but after half an hour of work I got the feeling that Safun copes with a similar task better, and this with the declared power of 2.5 kW.

trimmer for the grass “Baikal”, the declared capacity. 5.5 kW. Photo by the author when the ordered Safun was brought to the office, my other colleague became interested in my purchase. He had recently broken an electric trimmer for grass, which was fixed in the workshop in a couple of thousand, but after the repair he broke again, and finally. I told him about my trimmer purchased for mere pennies, he thought a little and acquired a similar, but more expensive-Procraft T-4350 for 6000. I was not too lazy and came to his cottage, helped to assemble the device, at the same time and tried to mow.

The declared capacity of the ProCraft T-4350 lawn mower engine is 4.35 kW, but when it is triggered by the difference with my own, I did not feel. Gasoline and fishing line consumption. The engine works quieter than Safun. In the first season of operation, this trimmer was dedicated to 100 acres in total. The engine started stably on cold and hot. The motor resource of the mowing is usually not indicated in the description. I could not find this information about my trimmer Safun. I had to evaluate it by the number of mowing per season. The mower worked out three seasons. I regularly open a summer area of ​​36 acres. To date, the “mileage” of the mower has amounted to 9-10 hectares.

Next, I want to share the experience of operating a trimmer for grass, small errors and breakdowns that I have encountered over the past three years.

The wrong selection of cutting elements

As a rule, owners of gasoline braids are divided into two camps. Some mowing both grass and weeds only with fishing line. Others, faced with high grass, immediately install a metal disk. I belong to representatives of the first camp. On a powerful two-kilowatt lawn mower, I am just scared to put a disk: everything flies from under it like from a gun. And with a worthy power of a braid for grass and fishing line, it easily cuts everything from hogweed to small bushes.

A fishing line for 3.2 mm with a diameter of 3.2 mm is installed on the Safun mower. Even three.month.old weeds on her teeth. Photo by the author

Working with a disk knife. Bad experience

For a very long time, my father.in.law and I put a disk on a powerful EFCO braid, she chopped bushes as in a fairy tale, which ended in the second season. They tore off the gearbox, and the workshop announced just an indecent amount for repairs. This case proves that the knife is not always the best option. When a metallic disk for a gearbox, an increased load, especially when the cutting part finds a stump or brick in the grass. Here the gearbox is overloaded, up to the breakdown of the teeth or jamming of the shaft.

Which line is it better for a trimmer

With a new trimmer, I began to experiment and tried a fishing line for a trimmer, which will be most effective. The instructions were allowed to install a fishing line for a trimmer with a thickness of 2 to 4 mm. For the first season I tried four species. a square 2.4 mm, a round 2.4 mm and 3.2 mm, a 2.4 mm twisted. With this power of the engine, I did not notice the difference. The consumption of thin fishing line was slightly larger, but for me it is not fundamentally. All fishing lines chopped thick weeds well.

I really felt the advantages of a square fishing line on a less powerful Honda. it cuts grass better at a lower engine power.

Good coil

The native coil of the new braid at first seemed to me flimsy, painfully thin walls! The forebodings did not deceive me: the first holes began to appear at the end of the second season, and finally it was rubbed after the first mowing in the third season. Replacement I found more reliable. The choice was small. you can buy the same, with thin walls, rubles for 300 or look more serious, which will live longer. I bought a more reliable coil with thick walls for 700. Everything is as usual: a good coil is more expensive and lasts longer. And there is no point in saving here.

Removing and disassembling the starter, replacing broken parts

To repair the starter of the trimmer for the grass, you will need to disassemble it first, and then collect it. This process is not a particularly difficult occupation. For work, you will need a screwdriver with the tip of the desired shape.

Everything should be done carefully, observing safety precautions, mainly that the spring does not injure the master if an accident.

Parsing the starting node

They disassemble the launch mechanism in order to install new parts instead of broken in the following sequence:

  • spin a screw with a screwdriver, fixing the pulley with a starter lid;
  • take out a spring and antennae;
  • Remove carefully with the pulley (you need to unscrew the head or work, having dressed the glasses and gloves before);
  • determine why the launch mechanism has broken;
  • If the spring collapses almost completely, then it is replaced;
  • When the spring exits from the hook, it is installed in the original place, bending the antennae before this (the photographs show the laying process);

To change the spring, you should work carefully and accurately: it can, under the influence of the effort caused by the installation of it in place, accidentally burst. Even if you carefully remove the video, then the spring strip flies very quickly from the coil and can injure your hand with its sharp edges.

Immediately putting a springy plate in the same place does not always work. It often slips, so attempts are required to repeat until the desired result is achieved.

Starter assembly

The assembly of the starting node is carried out in a number of stages:

When making the stated manipulations, it is necessary to lay two goals. If this is not done, then the spring over time damage the plastic cup, and when it is pulled. Because of this, a feeling appears, as if the spring had flown. To eliminate such a drawback, you need to install this part of a larger length or an additional goal.

When such spare parts are absent, you can just unscrew the screw a little, and the starter knot will begin to work without shaken. But this option is temporary. it is better to repair qualitatively as quickly as possible.

Spring tension

After installing the spring, it should be pulled. The following actions are performed for this:

  • Remove the handle from the starter cord;
  • Then the rope is inserted into the coil groove;
  • They stretch the spring, rotating the coil in the direction opposite to the clock of the clock arrow (reviews);
  • make the desired number of revolutions specified in the instructions for the use of the trimmer model used and the corresponding length of the cord used;
  • At the very end, the rope is threaded into a hole designed for this, located in the starter cover;
  • put the handle in place, fixing it with a node.

If after the repair the spring continues to fly, then you can get rid of this in the following ways:

  • Squeeze the suitable piece of the plate into the groove at the location of the spring hook;
  • drill holes on two sides of the groove in the coil, into which the spring hook is inserted and fix it using a wire.

Replacing a torn cord

A torn rope is replaced in the following sequence:

  • The old cord is removed;
  • choose a suitable rope (thickness and length);
  • Having reached it through a special hole in the coil, a knot is tied;
  • Sprinkle a spring, producing the required number of revolutions;
  • Fix the pen.

It is better to stretch the spring plate along with the partner so that the edge of the cord does not hit the starter mechanism.

It is easy to assemble a starter on a trimmer and wound a spring, only you should do it carefully and with caution. For different models, the gas tanks of the launching mechanisms are the same, so they are repaired in a similar way. In this case, there are some nuances associated with their constructive features.

How to properly adjust

Before setting up the carburetor trimmer for the grass, it is necessary to do the following:

  • Rinse the engine;
  • replace or clean the spark plug;
  • change to a new one or clean the air filter (it is recommended to lay it out in warm, soap water, squeeze it out and let it dry well).

It is also necessary to install the cord of the right diameter in the trimmer coil or install knives-this is done so that in the process of configuration the engine has at least some load. After installing a cutting tool and starting a gasoline engine, let it warm up for 10 minutes.

If at the idle speed of the motor you noticed that the cutting tool rotates, then it is necessary to reduce engine speeds. This is done using the lower idle regulator, often marked with the letter “T”. The figure below shows the placement of regulators on the trimmer Husqvarna.

But, for example, on the STIHL trimmer, this screw may have a label “LA”.

So, turn the idle control regulator to the left, until the trimmer head is completely stopped.

To configure the carburetor, 3 regulators are used (screw).

  • The right regulator L tunes the level of enrichment of the combustible mixture at low speeds. It needs to be adjusted by the first. Get a maximum of turnover at idle. This is done using the regulator L, turning it to the left and right. After finding the point of maximum revolutions, return the regulator for half a turn to the left (against h. Arrows).
  • The lower regulator t (LA) is used to configure idle. Turning it to the left, the engine speed will begin to decline, and when the regulator is turned to the right, the revolutions will increase.
  • Left regulator h is responsible for enriching the combustible mixture at high speeds. The enrichment configuration completes the adjustment of the carburetor. Also, using this regulator, you can configure maximum speed, fuel consumption and engine power.

Important! If you allow the engine to operate at full speed for more than 10 seconds, then it may fail.

To exclude this trouble, adjustment will be required. With the working motor, give a full gas, then turn the “h” regulator to the right until a reduction in revolutions begins. After that, the “h” regulator must slowly scroll to the left until you hear the uneven operation of the engine. Then the regulator “h” should be rotated to the right until the moment of flat operation of the motor is heard.

After conducting the above actions, the setting of the carburetor can be considered completed. After proper adjustment, the engine must confidently gain momentum, a little four at a maximum of revolutions, and when working, an idle cutting tool should not turn. This manual is suitable for adjusting carburetors on the Huter, Patriot and others benzocos.

There are also carburetors without a screw that is responsible for enriching the combustible mixture at low speeds. That is, they have only 2 adjusting screws: a idle regulator and a quality fuel mixture regulator at high speeds. How to configure a carburetor of this type, you can find out from this video.

Electric trimmer for grass: device and principle of operation

A power cable with a fork is connected to the trimmer body for grass, through which electric current is transmitted. In the cavity of the detachable bar is a flexible shaft, thanks to which the torque is transmitted to the trimmer coil. The device is turned on by pressing the button located on the device handle.

This design of a trimmer for grass is the most common, but

If desired, you can find products working from the battery, as well as with the lower location of the electric engine.

Lower motor trimmer for grass

If the area is not very large, for example, 2-3 acres, it is better to buy a trimmer for grass with low-power electric motor (up to 400 W) installed in the lower part of the device. He is able to perfectly mow soft grass in flower beds and flower beds. In addition, this garden tool copes with delicate work perfectly. If you need to, for example, carefully cut the grass between flowers or seedlings, it will easily complete the task, as it has a rather small diameter of the rotation of a braid fishing line. Trammers for grass with a lower electric motor are also used to regularly mow grass, which is much softer than usual. They have a fairly short work schedule, and they often have to rest. It is important to remember that such trimmers for grass cannot be used to cut wet grass.

Lower trimmers for engine grass are light. In addition, they are very maneuverable, t.E. The cutting surface (fishing line for a trimmer) can rotate at an angle convenient for work, and cut the grass even in almost inaccessible places. Devices with a lower engine position are very well balanced, it is very easy to work with them even with one hand. The advantages of this equipment also include their small size.

And now a few words about the shortcomings of trimmers with a smaller engine. All of them have a power of not more than 650 watts and are not equipped with steel knives.

Preparation for the first launch of the lawn mower

Before carrying out the first launch of the lawn mower, it is necessary to perform a number of consistent actions:

Checking the gearbox before starting a gasoline trimmer for grass must be carried out on a regular basis. The lack of lubrication or its small amount increases the friction of the gear gear of a gearbox operating at fairly high speeds. As a result, overheating and gears occurs. Motokosa gearbox fails. To prevent the occurrence of such a breakdown during operation and the regular inspection helps.

Fuel pressure regulators

The range of tubular sensors includes. Without emergency contact, a negative grounding pole or isolated without emergency contact, a negative grounding pole or an insulated with an alarm, a negative grounding pole or isolated without emergency contact, a negative or negative pole or isolated. Fuel pressure regulators have a function of maintaining constant fuel pressure. If the pressure is too large, the device allows you to open the reverse channel, allowing excessive fuel to return to the tank.

If, before the launch of a gasoline braid for grass, an insufficient amount of lubrication in the gearbox or its absence in the case is laid “litol”. To do this, it is necessary to unscrew the screw on the bend of the gear housing and the “lilest” in the amount of 1-2 ml.

The exact amount of the fuel required for the engine is calculated from the control unit at any time. The injector performs the task of measuring and quantitative determination of this amount with accuracy and within the time period determined to ensure the pure and efficient use of the fuel itself.

We clearly emphasize their Accent at home masters because they are allocated in the leadership of each tool or machine. The family of the Sender includes more than 300 different tools and machines, of which drill and hammers are most famous, as well as a large group of manual tools and woodworking stationary machines, the range of inverter welding equipment and compressors, etc.D.

Working with a gasoline trimmer for a long time, every 8-10 mothers add grease to the gearbox of the bar.

Preparation of the correct fuel mixture

Before starting to run the new engine of the lawn mower, you must also prepare the fuel mixture correctly. As you know for two.stroke engines, it is prepared from special two.stroke oil and gasoline, taken in certain ratios. You can find out proportions from the instructions attached to the tool, or on the labeling label. From the instructions you will also learn the recommended type of fuel, as well as the recommended type of motor oil.

Currently, it is a total of 22 models of pumps that differ in their power, expenses, pressure of the absorption of depth and height. Hydropher systems are used to automatically control the pump depending on the flow of water. They have the same application as mechanical pressure pumps. wherever it is necessary to provide a continuous flow with a constant flow of water. Typical accelerators are also that smooths out the inevitable orientation of the water jet when starting and stopping the pump.

The hydrophore system is a water pump, the pressure nozzle of which is connected to the high.pressure airtight metal vessel. The most commonly used technical solution is its interior is divided on a flexible rubber membrane, thus forming two spaces. one is filled with water and the other is closed by air. Excessive pressure is associated with air space of hydrophore.

Cook fuel in small quantities sufficient for one mowing grass. Use special canists made of plastic for fuel, or a separate glass or metal dishes. It is best to type oil with a medical syringe.

Having gathered to run into a new lawn mower, many are faced with the problem in the preparation of the fuel mixture. And the reason for this is the disagreement in the instructions of the tool manufacturer and in the instructions of the manufacturer of motor oils. The first recommend a 1:25 proportion. The latter recommend 1:50. Who to believe? How to proceed?

assemble, trimmer, grass, shape

The pump is supplied in the line water with certain pressure, which begins to grow when the amount of water that is absorbed becomes less than the flow of the pump or the water fence stops. Upon reaching the specified limit pressure of the air, the pressure relay turns off the pump, and the water in the water line remains under the pressure of compressed air. When the tap is opened, water first flows under the influence of this pressure. For this reason, since the volume of the tank is greater than the smooth system will work, and the pump will be less frequent.

When the lower limit of a given pressure is achieved, it includes the pump and begins to supply water to the system. The method of hydrophore operations softens the inevitable sudden changes in water pressure when the pump is turned on. This type of pump is intended for houses and other objects, the water supply of which is provided from its own source. The pressure sensor automatically turns on and off the pump depending on the pressure of the water supported in the pipeline. When it falls due to the drain of water, the pump turns on and goes out as soon as the pressure exceeds the given value.

According to experts, if in the instructions for a motorcycle, manufacturers write a proportion of 1:25 or 1:30, then it is most likely a cheap tool with poor cooling, or the manufacturer does not know what kind of oil will be added to the consumer. But here it must be understood that the excess of lubricant does not affect the performance of a trimmer for grass in the best way. Excess oil does not completely burn out when operating the engine. It cokes, clogs a cylinder and piston.

This solution successfully replaces the classic hydraulic system with more complex maintenance and larger sensors. Automated control also greatly facilitates the provision of the required amount of water, saving water and electricity. In addition to residential, production, livestock and other facilities, electronic control pumps are also suitable for irrigation plants.

The pump body is made of stainless steel. This type of pump, also called whirlwind, is used to pump only pure water. The presence of solids can easily turn off them. Their positive aspects. The low cost and high height of the water column reached by one workplace, as well as a lightweight deaureation of the suction line. The first has an electric motor 370 watts, and the second. 500 watts.

What to do in this situation when running in a new tool? An ideal option would be to purchase exactly the oil that the manufacturer of the lawn mower recommends. In the case of run.in engines, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two.stroke oil for the same gas tool. It costs not cheap, but there is enough it for a long time. It is necessary to interfere with it as it is written in the instructions on the bank.

They are usually designed to pump pure water, but also have a certain minimum solid particles. To absorb water, absorbing fishing line for a trimmer and the pump must be filled with water. They are mounted in a dry place protected from dust. Its significant advantage is that it is cheaper than multi.stage centrifugal pumps with similar parameters.

In addition, dehydration of the suction pipe is greatly facilitated. At the same time, due to the small diameter of the hole of the ejector, this type of pump is more sensitive to the presence of solid impurities in water, which may cause its clogging. These types of pumps have recently been widely spread because they are extremely convenient, t.e. Practical and universal. They are equally successfully used to empty water pools and decorative lakes, underwater water shafts, drainage basements and other rooms, emptying drainage mines, pumping water from a deep well, etc.D. They have a waterproof structure and, as the name can be seen, work on the water.

Remember, it is best to use the proportion that the oil manufacturer gives. But is that proportion that is written on a spit is better to find out by experiment. If, with a trimmer recommended by the manufacturer for grass, the proportion of the engine sniffs with oil and the subteids are visible on it, then the proportion must be increased.

Malfunctions and their elimination

Electric and gasoline trimmers have typical breakdowns and malfunctions. For devices running from an internal combustion engine, this is:

  • problems in the carburetor;
  • engine breakdown;
  • problems with the fuel system;
  • breakdown of the gearbox, starter, muffler;
  • blockages;
  • Air filter breakdown;
  • Problems with ignition coil.

Electric units have specific breakdowns:

With simple problems, you can make a trimmer repair for grass with your own hands.

Why is a trimmer not starting for grass

The most common reason that the unit does not start is the use of poor.quality fuel. The choice of gas stamps below AI-92 can disable the lawnical mower. If high.quality fuel is used, you need to look for other reasons. To do this, carefully check all nodes and systems. The checks are subject to:

The device may not start after prolonged downtime. Before turning on a trimmer for grass, you need to study well the instructions for operation. The solution of many problems is indicated in it.

If it stalls when you press the gas

There are several reasons why a trimmer for grass stalls when gas is pressed:

  • The first reason is the dumping of the carburetor.
  • Fuel valve.
  • Fur valve blockage.
  • The weakening and sagging of the carburetor cable or sagging of the fuel intake hose.

So that the described problems with the lawn mower do not arise, you need to carefully monitor the condition of the device and its blocks. Timely cleaning, washing of the unit and spare parts allow you to increase its life.

Starter breakdowns

The most difficult breakdown of the starter occurs when the rope is broken and winding it into the flywheel of the operating engine. As a result, the spring may burst and the pulley plunges. In this case, only a complete replacement of the spare part will help. This breakdown rarely occurs. often:

In this case, it is easy to fix the starter yourself. The manufacturer has prepared a step.by.step instruction for this.

REDUTOR Repair

Caring for the motorcade gearbox consists in the timely lubrication of the unit. The absence of one can lead to rapid wear of the gear and jamming of the gearbox module.

The main malfunctions of the trimmer gearbox for grass:

  • severe heating of the gear component due to the use of low-quality lubrication or its absence;
  • shaking of the shaft during the rotation of worn bearings;
  • staggering or flowering from the bar of the gear ratio as a result of damage to the case;
  • Lack of rotation of the output shaft with a knife due to wear on the teeth on the gears.

Most of the malfunctions in the gearbox are associated with the destruction of bearings.

This happens due to the use of low-quality lubrication or its complete absence. Another reason for the failure of the gearbox is the operation of a trimmer for grass at the limit of its capabilities and the hit of foreign objects. To replace a faulty bearing, a gearbox is disassembled.

Features of the repair of electric models

Electric models of trimmers operating from the network have several main blocks:

Each electrimmer block has specific problems. In the mechanical part, they depend on the presence of a fishing line used as a cutting element. Reasons for the termination of work:

You can identify the problems of the electrical part of the electrocos using special tools:

To eliminate problems, a soldering lamp is needed.

  • a malfunction of the power cable;
  • problems with an outlet and fork;
  • the failure of the control handle;
  • combustion of the starter winding, engine replacement is required;
  • Contact breaks can be corrected independently using a soldering lamp.

How to adjust the carburetor

The module adjustment is carried out by the manufacturer. During the operation of the device, after repairing or cleaning the module, it becomes necessary to adjust the carburetor.

Carburetor setup does not require replacement of spare parts. Debugging is done with the help of 3 screws that are available in the design:

  • L. controls the supply of fuel at low speeds;
  • H. controls the fuel consumption and temperature, and is also responsible for supplying gasoline at high speeds;
  • T. is responsible for the idle engine.

Adjustment of the carburetor of the trimmer for grass is carried out after the engine warms up. For this, 10 minutes of operation of the device at idle will be enough. The rotation of the mowing head at idle allows you to start directly to debug the screw t. It is turned counterclockwise to the cessation of rotation. Then the screw h is scrolled to the right and left to find the position in which the idle speed will be maximum. The screw is turned off on ¼ full turnover counterclockwise from the found point, this will be the working position.

According to the same technique, the screw l. After repairing the carburetor, the module is necessarily tuned so that the device works correctly.

Asseting device and common malfunctions

The easiest way to give the lawn mower for repairs, allocating a certain amount of funds from the family budget, operational and high.quality repair with your own hands is no less simple and convenient to understand the design of the lawn mower and fix all the problems.

  • top part. The basis of the entire structure, where all important elements are collected, such as the starter, carburetor and the engine of the lawn mower;
  • middle part. Hollow rod, inside it is a cable connecting the engine and gearbox, which sets the cutting fishing line for the trimmer. In this part there are mounts for the distribution of weight of the entire structure and a belt for fixing a trimmer for grass on a belt of a person using a trimmer for grass for its intended purpose;
  • Bottom part. It has a gearbox and cutting elements that are hidden under a practical casing, which protects the user. The casing provides an increased level of safety, preventing large fractions of garbage, pebbles and glass in a person while working with a gas station.

Knowing the internal device and the principle of operation of the trimmer for grass, you can independently carry out repair measures for the design or replace individual unusability of the nodes using the repair instructions.

  • engine malfunction, due to which the lawn mower is not started and does not work;
  • enhanced vibration of the bar motorcosa, which complicates its targeted use;
  • increased overheating of the gearbox, its accelerated heating during operation;
  • slow and weak functioning of the cutting fishing line at insufficient speeds;
  • the clogging of the starter grill causing the engine overheating and its refusal to work;
  • rapid and frequent clogging of the carburetor due to the use of poor.quality fuel;
  • clogging of the air filter in case of non.compliance with measures to care for the device.

All these problems can lead to the fact that the device will lose its ability to work before ordering the necessary spare parts for non.bosomeds should be carried out by a visual inspection and diagnosis of the device.

Special attention is required by individual spare parts and assemblies of the device, to verify them, you will not have to turn to a professional master, a complex of diagnostic measures will help to identify a consequence of the occurrence of a loss of performance.

Determination of the causes of the malfunction

If the trimmer engine for grass does not start or stalls immediately after starting, when overheating or during the functioning of the device, extraneous noises are heard and vibration is clearly felt, it is important to perform a visual inspection and identify a non.working node.

  • the presence of fuel in the tank and lubrication in the main nodes;
  • serviceability of the spark plug and its performance;
  • the purity of the fuel and air filter motorcycles;
  • Cutting of the exhaust channel and the device’s saepun;
  • The quality of the used fuel and lubricants.

To determine the functional performance of the ignition of the lawn mower, you should determine whether the candle works by testing the appearance of a spark in contact with the body of the functional device.

The spark plug itself can be changed to a new one, after driving the candle canal, if necessary, the old element is also dried, cleaned with special devices and returned to place.

How to remove the coil and replace the fishing line for the trimmer

The owners of the trimmers, mainly beginners, confuse, bordering on panic, when it becomes necessary to change the cutting tool or fishing line for a trimmer in a reel. Very often, when trying to unscrew the mowing head, users simply make it unusable, not suspecting that it is unscrewed in the opposite direction. So that this does not happen, if you need to replace the tool, it is recommended to familiarize yourself with the step.by.step instructions given later.

  • Before refueling the fishing line for the trimmer to the coil, drown out the engine of motorcycles or de.energize the ethletric trimmer for the grass to avoid injuries that may occur in case of accidental rotation of the cutting tool.
  • Unscrew the nozzle mounted on the gearbox shaft. To do this, the shaft must be fixed by combining holes on the puck and on the axis, and inserting a metal rod or screwdriver into them.
  • Unscrew the nozzle. You should know that the thread on the shaft is left. Therefore, to twist the coil of the trimmer for the grass should be right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the fixers. To remove it, you need to drown these latches into the case, pressing the edges of the lid. If your trimmer has a semi.automatic mowing head, which has a button from below, then disassembling the nozzle should be done carefully, since you can lose a spring that sometimes flies away when removing the cover.
  • Cut the required amount of fishing line. Usually its length is 5 meters. Use the cord of the diameter that is indicated in the instructions for the tool. It is not recommended to exceed the maximum diameter of the fishing line, since this will lead to increased load on the engine and greater consumption of gasoline.
  • Find the middle of the segment of the cord, folding it in half. You will get a loop.
  • Special grooves are cut out inside the coil (there may be holes). Insert the loop from the fishing line into this groove.
  • Wind a fishing line for a trimmer to a coil, turning it counterclockwise. You need to refuel the cord as evenly as possible, the turns should be laid without ceiling and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the coil.

Is it possible to make a coil for a trimmer for the grass with your own hands

On sale there are a large number of trimmer heads (not automatic), which have a low price and good quality. But sometimes situations arise, for example, in the country, when the trimmer coil broke, and its repair is impossible, the store is far away, and you need to mow. In this case, you can quickly, literally in a few minutes, make a simple trimmer nozzle to fix the fishing line from ordinary plywood 10-12 mm thick.

  • Take a piece of plywood or textolite and draw a circle with a diameter of about 14 cm on it.
  • Cut the disk with a jigsaw or hacksaw for metal.
  • Drill a hole in the center of the disk, suitable in diameter to the gear shaft. Do not forget before installing a disk on the shaft, put a puck on it.
  • You can fasten small corners along the edges of the disk or make 1-2 holes on the opposite sides. They will serve for refueling fishing lines in them.
  • To fix the fishing line for a trimmer, you can screw several screws into the plywood.

Such a homemade mowing nozzle is fixed on the shaft with a nut. Twist or unscrew the nut without fixing the shaft will not work. To replace the cord, it will be enough to release the screws, insert a segment of the fishing line of the required length and press it again.

Also, a mowing nozzle for fixing the fishing line on it can be made from a metal sheet. How to do this can be understood from the next video.
