Why the lawn mower and a trimmer for the grass do not start possible causes and ways to eliminate them

If a trimmer for grass or a lawn mower is not started, then any desire to mow grass disappears. Very often, the owners of these tools face difficulties in starting a two.stroke or four.stroke engine after winter, when the tool was not operated for a long time. If this situation has occurred, then do not rush to take the tool for repair. Start finding a malfunction from less to larger, and with a 100% probability you will be able to start a benzotrimer engine. Where to start searching for a malfunction when the lawn mower does not start, we will consider step by step with all the details.

Hand starters are used to launch gasoline trimmers. Through such starters, manual movement of the crankshaft is carried out. At the same time, it is important to turn on the ignition so that when the crankshaft rotates, the fuel mixture entering the cylinder could be ignited. Inflammation of the first portion of the mixture will entail the launch of the engine, and at the same time the trimmer for the grass is ready to operate.

However, it often happens that attempts to start the engine come to naught. Naturally, when after 5 attempts to start the engine, it is not possible to achieve success, then you need to start diagnostic measures. There is a special sequence that should be followed to find the reason why the lawn mower is not started, and successfully eliminate it. The sequence of verification has the following format:

  • Check the presence of fuel in the tank, as well as the quality of a mixture of gasoline with butter
  • Determine the color of the spark plug, as well as signs of its functioning
  • Make sure an air filter
  • Check the fuel filter that is responsible for cleaning gasoline with oil entering the carburetor
  • The serviceability of the sapun
  • The reason that the lawn mower is not started, there may be a exhaust channel or muffler

It is these nodes that are the main sources of the problem of difficult trimmer for the grass. A more difficult problem is associated with a malfunction of the carburetor, which needs to be adjusted. Consider each node separately to find out the reasons why the trimmer for the grass does not start, and eliminate them with your own hands.

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.

First of all. check the presence and quality of fuel

Do not understand why the lawn mower is not started, then initially make sure that there is a fuel in the tank. Often, beginners forget that it is necessary to periodically make pauses to season the tool with a gasoline mixture. If the gas mushroom tank is empty, then of course it will not start, no matter how much you try to do it.

If there is a fuel in the tank, but it is impossible to start the tool engine, then do not rush to disassemble the carburetor. Make sure that the trimmer engine is launched correctly, as indicated in the instructions. If the launch is carried out according to the instructions, then it is important to consider the following points:

Starting a Gas String Trimmer

  • Use not just high.quality gasoline with the maximum octane number, namely the brand recommended by the manufacturer. And far from always such a brand is AI-95 gasoline. If you do not know which gasoline is used for the lawn mower, then choose AI-92
  • The oil should be special. for two.stroke engines. If the lawn mower has a four.stroke engine, then pure gasoline must be poured into it without stirring with butter. On the quality of the oil for the engine engine, the grass should not be saved, as well as on gasoline. After all, the operational resource of the motor depends on the quality of the fuel used
  • Proper preparation of the fuel mixture in a benzotrimer. Observations show that most mowers are only the first time control the process of cooking oil with gasoline for a trimmer for grass. The greater the experience of Kosar, the less close attention is paid to the process of mixing gasoline with butter for a two.stroke engine. The ratio of gasoline with oil should be the way the manufacturer recommends. Typically, this ratio is 25 to 1, that is, 1 liter of gasoline needs 40 ml of two.stroke oil (motor oil for the car and even more so you cannot use it)
  • Proper storage of fuel mixture. It often happens that after the preparation of the fuel mixture, it costs for a long time for more than 2 weeks. It is impossible to store the finished mixture of gasoline with oil for a long time, as this leads to the fact that the oil is precipitated, and thereby the properties of both oil products are lost. Even thoroughly stirring after prolonged storage of the finished mixture is not a reason for its further use. That is why it is not recommended to prepare more than 2 liters of the mixture at a time

Make sure that all of the above points are made, and only after that you can start checking the condition of the candle. A trimmer for grass is not started for various reasons, and most of them can be identified independently. Resorting to disassembling the carburetor, if it is impossible to start the engine, is simply irrational. The next step towards finding a malfunction is a check of the state of the spark plug.

Varieties of gasoline units for mowing grass

A variety of units are produced today.

Professional lawn mowers have the following features:

start, trimmer, grass, gasoline, champion
  • The engine of the gasoline-type mowel is launched in different ways. Using a special key on the control panel, the starter starts the engine from the battery. With the help of Dergach, a manual launch machine starts up.
  • Various methods of processing cut vegetation are used. Small grass is discarded directly to the turf, used for mulching or assembled in a special container. A bag for collecting grass must be regularly devastated.
  • Mulching mowers are equipped with engines with a four.stroke or two.stroke process. They differ in the features of the working cycle, power parameters.
  • Maneurated self.propelled devices have high actual performance, since the large parameters of the mowing width allow you to process extensive territories per unit time. In the process of processing flat land arrays, a manual self.propelled lawn mower is successfully used. The equipment is equipped with a drive mechanism to wheels.
  • Gasoline devices in which the front wheels are leading are needed in crossed terrain. They have a great rating. The rear.wheel drive units are used on the flat surface of the land arrays. It is always relevant when processing a small lawn overgrown with grass, a design with rear.wheel drive.
  • The volume of the fuel tank of gasoline lawn mowers is important when choosing a model if you have to process a significant area of ​​turf with high grass and other vegetation. Additional refueling is not needed.

Playing Chinese lawn mower and operation issues. Practice

I continue to share the first impressions of the Tatra motorcycle. In this video I will briefly tell about the first start.

The first launch and run-in Motokos Tatra BCU-73

how to run the lawn mowers and chainsaws correctly.

mechanical. to defend and store gasoline for work not in metal containers and not longer than 1 (one) month, otherwise it oxidizes and loses its properties;

chemical. impurities and additives should not be present (they have different speed, degree and temperature of combustion). Old gasoline turns yellow or reddish, and impurities have pungent smells of bitterness (for example, creosot) or acid (for example, methyl alcohol).

The proportion of the fuel mixture is 1:50 (2%) or 20 ml/cm3 of oil per 1 liter of gasoline. For example, pour half a gasoline measure into a transparent plastic bottle (1 l), then administer a two.stroke oil with a medical syringe (20 ml/cm3) and mix, add gasoline and mix thoroughly. If the quality of gasoline is doubtful or the working conditions are difficult, then the amount of oil can be increased to 22-25 ml/cm3. Before each refueling, shake the mixture! Store the resulting fuel for no more than two weeks! If the color of the mixture has changed (from the color of the sea wave, for example, brown), then it is not recommended to use it!

We proceed to running the lawn mower

After starting, do not rush to immediately run the trimmer for the grass. Let the engine idle for 5 minutes. While heating is going on, adjust the air supply to the air damper with a lever so that the rogue with a fishing line or with a knife does not rotate. As soon as the tool warmed up, we completely open the air supply to the corresponding lever to the “ON” position and squeeze the gas trigger for 1/2 and hold the seconds of seconds 30. Then we drop the gas, let the trimmer work on xx 3040 seconds. In this mode we continue 10 minutes 15. Then we mock and let it rest for 15 20 minutes.

Having cooled the lawn mower, we continue to run the engine according to the previous scheme. Start a hot, a trimmer for grass should already be with an open air damper. Try not to hold the gas for a long time, since the movable details of the tool only rubbing each other. And do not let the engine work at idle for a long time as it can overheat.

The next stage is the a gas reducer gearbox for grass. To do this, select a plot with soft young grass. Kosim 5 10 minutes with 1/2 2/3 from full gas. After we take a break for 20 25 minutes. Repeat the cycle 3 4 times.

In general, therapist for the lawn mowing according to the described algorithm is carried out until the fuel mixture in the tank is fully generated. After which the tool is ready for long.term work. In the process, follow the temperature regime of the gearbox and the motor. They should not overheat.

Motokosa service (trimmer for grass)

Engine. The air filter should always be clean (without dirt or sawdust); foam filter must be wetted with oil. The fuel filter must be checked once a week, in the case of intensive use of the tool, if necessary, to replace it in time. Checking the tightening of nuts and screws. before starting work. Cleaning from a muffler carrier (or its grid) and candles. if necessary.

Cutting discs. The cutting faces should be well and properly sharpened using the necessary templates and files (emery), in compliance with the angles of the cutting parts depending on the brand of the disk. Double.sided disks regularly turn over 180 ° and wear out evenly. A dumb disk or a disk with poor or improper sharpening does not cut well, and thereby overloads the engine, which leads to an accelerated reduction in its motorcyclear.

Trimmer fishing line and trimmer heads. Use only a special braid line for a trimmer. do not use wire or metal cables! Install a fishing line for a trimmer only of the diameter that is recommended by the manufacturer. Wind on the bobbin tightly, but do not cross the turns. Clean the mowing head from dirt and, if necessary, lubricate. A worn or deformed head can disable a gearbox and/or shaft motorcycles.

Corner gearbox. As necessary, cleaned of dirt (such a “fur coat” does not allow the gearbox to cool normally) and add a consistent lubricant of Husqvarna, or similar, for a reducer pair.

Protective covers. It is forbidden to work without a protective casing. this is dangerous for the life of the operator and others, and can also overload the motor motorcycles. For each type of cutting equipment, only its own protective casing, provided for by the manufacturer, should be used.

Independent repair of motorcycles

It should be noted that it is not always possible to independently repair motorcycles, but in most cases, small repairs are possible for everyone.

If a trimmer motor broke for grass, and you are not a car mechanic and not an electrician, it is better not to try to fix the mechanism. There is a chance that you cannot collect it back. There may be such problems: low compression in the engine, the engine jammed, the carburetor failed. If these phrases do not tell you about anything, then you should not repair the motorcycle for the picture and intuition.

It should be noted that the maintenance and repair of the chainsaws and motorcycles are largely similar.

A trimmer for grass consists of a bar, a motor (happens from above or below), and a mowing head with knives, various additional elements. What can be repaired here yourself?

air damper; 2. handle; 3. engine stopping device; 4. throttle control lever;

5-bracket limiter; 6. bar; 7. protective device of cutting devices;

1) If the swallowed a toggle switch is turned on, and you are familiar with simple electrical circuits and are friends with a soldering iron, solder and rosin, then you can easily replace the toggle switch with a new. They are sold in electrical equipment and lighting stores.

2) if the wire limiter from the mowing head has disappeared, it can be wrapped with flexible copper or aluminum wire to the bar. You can also make a new mount from a strip of stainless steel.

3) If a fishing line for a trimmer in the drum of a mowing head is torn. nothing is easier than replacing it on your own. You can, of course, just buy a head for motorcycles separately and replace it, but a fishing line for a trimmer will cost a hundred percent cheaper. The optimal material here is a fishing line for a trimmer from 0.9 to 1.5 mm, nylon or nylon. Measure the diameter of the used fishing line at once, before it ends completely. Thinner. can break, thicker. causes engine overheating and unnecessary vibration. You need to disassemble the drum and wind the fishing line for a trimmer manually, then collect the drum.

4) if the bar breaks, it can also be repaired by scraping and gluing to wooden rails or iron brackets.

5) If strong vibration has begun, and the engine began to work “unevenly”, perhaps a motorcycle has a lubricant. Any trimmer for grass is easily disassembled, it is recommended to lubricate it with technical oil at least once a year.

7) If the trimmer for grass is equipped with plastic knives, and they were deformed for some reason, there is a way to replace them with metal. To do this, you need to make several stainless steel knives. This is difficult at home, but a familiar turner operating in an industrial enterprise or factory will be able to save the situation. Knives are attached to the shaft using a sleeve with a puck. Such modernization will lead to the fact that a trimmer will become possible to mow grass of any stiffness. But caution when handling such a trimmer should increase.

8) the engine does not start? To start a braid, sometimes even hot, it is necessary to completely close the damper to enrich the mixture. Check the flow of gasoline, clean, if necessary, replace the glow of incandescent.

The location of the main parts and controls

Assembly of the lawn mower

Remove the lawn mower and components out of the box. Check the lawn mower for the lack of mechanical damage.

Install the handle in the working position and fix it with special locks (a) (rice.3). Check the installation of control cables, they should not be overthrown. Install the grass collector. To work with the possibility of side emission of grass, install a groove for the release of grass (rice.4).

Install the handle in the working position and fix it with special nuts (rice.2). Check the installation of the engine shutdown cable, it should not be pushed.

Set the starter’s handle in the guide bracket on the working handle (rice.5).

Unfinished engine instruction how to start equipment (gasoline lawn mower):

  • Disable the transmission, ignition system.
  • Scroll the motor shaft with a starter, launch cord.
  • Turn on the ignition.
  • Close the air damper.
  • Run the engine.

If the lawn mower is not started:

The first engine launch may require approximately 15 jerks.

With a successful engine start:

Work with an engine that is not warmed up, leads to a decrease in the performance, durability of the device.

How to wind a fishing line for a trim for a lawn mower

Winding a new cord on a reel. a rather easy process. For work, a skein of a new fishing line of the desired diameter and shape, a knife for cutting and protective gloves will come in handy for you. The following is the scheme for replacing the fishing line with a reel with 2 antennae, as this is the most common version.

  • Cut the fishing line for a trimmer 2-4 m long (the length of the segment depends on the thickness of the cord and the tips of the manufacturer). Do not use the cord of the larger length, since it will rotate and stretch worse when running.
  • Remove the trimmer head from mounting (each model has a different method of fastening-special latches or a barashka nut) and disassemble it. Gently spread all the details nearby, losing nothing.
  • Wind a fishing line for a trimmer to a reel. There are 2 types of coils: with a dividing side and without it.

  • Fold the fishing line for the trimmer in half and put on the bending place on a special groove in the coil. If it is not, simply cut the cord into 2 parts along the fold line and fix the ends in the holders.
  • Pass the tips in special gutters on each part of the coil.
  • Start wrapping the remaining length of the cord in one direction.
  • Leave 20 cm at the ends and place them in opposite directions, stretching into special holes.
  • Cord the cord of the desired length in half.
  • Fix the tips in a coil in special mounts or drive into the holes.
  • On the bobbin indicates the direction of winding, in which direction you need to wind the cord. Wind up, not allowing segments to cross the coil.
  • Dilute the ends on the opposite sides and insert into special slots. The diameter must match.

Important! Buy a corporate cord, which is recommended for your lawn mowing model. It is stronger than cheap analogues and will serve longer. Also pay attention to the diameter of the holes in the coils with a dividing side to choose a fishing line for a trimmer of a suitable section. Do not wrap the fishing line for the trimmer tightly, provide it with free move during work.

To wind a fishing line for a trimmer to a coil with 1 cutting end, you should not fold the cord, and for mowing heads with 4 antennae, you should prepare 4 pieces of fishing line. Winding scheme is the same as described above.
