OLEO-MAC benzocylet is not started. Playing the new engine: where the danger is hidden

Trimmer does not start for grass. Why?

A gasoline trimmer for grass is an amazingly useful thing, with which you can, without unnecessary troubles, put in order not only a miniature lawn in the backyard of the house, but also to dig a considerable size of the lawn. But, like all things in this world, it has the ability to break. In this article, we will try to figure out what to do in cases where a trimmer for grass refuses to work.

So, what to do if the gasoline trimmer for the grass is poorly started or not started at all? The most common reason for such a breakdown.This is poor.quality fuel. Remember that, for example, trimmers for the grass of brands “STIHL” and “Husqvarna” are unlikely to start the quality below AI-92. Do not save on fuel, t.to. Repair of cylinder parts.the piston group can be a third of the entire cost of a braid for grass, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.

What to do if high.quality fuel is flooded in the gas tank, there is a spark, but the tool still refuses to start up? It is necessary to check the condition of the candle. It is located in the center of the gas mowing housing. It needs to be carefully twisted and make sure if there is a raid on it. If it is, then carefully clean the candle from the carbon and dry it.

If the lawn mower does not start even after the methods proposed above, then you need to try to remove the air filter and start the device without it. If the trimmer for the grass has not earned, clean the old filter well from dust or buy a new one.

It also happens that the lawn mower works as a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try to open the pouring cover of a benzogornin. a suction sound should appear. After that, tighten the lid back. If you do this manipulation during the time when the trimmer for the grass has just begun to stall, then the turns will recover, and it will be possible to continue to work. If the lawn mower stalled until the cover is opened, then you just need to start it as it should be according to the instructions.

Trimmer for grass does not start after winter

How to be in such a situation? Do not worry and panic. This is a very common problem that is solved in just 3-4 minutes. Firstly, if the fuel is left in the gas tank last year, then it must be drained. Gasoline loses its octave properties after 2 weeks of downtime. Secondly, start a lawn mower after a long stagnation in a slightly different way. First you need to open the damper and pump up a little fuel mixture into the carburetor, then stretch the handle until a small resistance is sensed. After that, you can start a trimmer for the grass.

If, when trying to start a trimmer for the grass, it starts up, but immediately stalls, then the cause of this may be an air filter again. It is necessary to remove it and check if it is clogged with dust. If this is true, then it is necessary to carefully clean it or purchase a new. Also, the problem may also consist of malfunction of the ignition coil. In this case, the lawn mower is best taken to the service center.

How a two.stroke engine works: briefly, but it is important to know for a clear launch of a lawn mower

Lawn mowers are produced with two.stroke or four.stroke internal combustion engines. The difference in the design is significant, but each model starts on the general principle. I show on the example of the Chinese trimmer for Eco grass.

The engine is called two.stroke because the full.time cycle is two tacts: the stroke of the piston from the upper dead point of the VMT to the lower NMT. In this case, the launch occurs with the second achievement of the upper position.

Similarly, chainsaws, boat engines and gasoline tools of another similar technique work. Consider the procedure. We are supposed to figure it out.

To start a trimmer motor for grass, we pull the starter’s cord. Its stretching is spinning a crankshaft with a flywheel creating the moment of inertia. The rotation of the crankshaft shaft is converted into the reciprocating movement of the piston.

The two.stroke motor has 4 working cycles:

• The first movement of the piston from the VMT to the NMT is accompanied by the injection of the fuel mixture (gasoline with butter and air), when the carburetor inlet valve opens under the influence of the created vacuum;
• The movement of the piston from NMT to the VMT: the intake and exhaust valves are closed, and the working mixture is compressed in a sealed volume;
• Both valves remain closed. At the upper dead point of the piston through the contacts, the spark slides through the contacts.There is an explosion of compressed gases. Its strength with an impulse throws the piston down and rotates the crankshaft through the connecting rod;
• The force of inertia of the flywheel directs the piston from the NMT up: the exhaust valve opens and through it the combustion products are pushed into the exhaust pipe.

All stages are performed automatically, but they are prepared by a person with his actions. When making errors it is made, the benzotrimer does not start and may break.

I try to make out all these points in more detail.

Cycle: what mistakes of beginners lead to breakdown of the engine of the trimmer for grass and exclude its normal operation

6 common mistakes with fuel

The manufacturer in the instructions clearly indicates the brand of gasoline with an octane number, oil and their proportions.

The first three errors are that the user of motorcycles violates all or one of these requirements. The motor will most likely start and work, but its resource may decrease sharply.

A small amount of oil, like its absence, will lead to the fact that the walls of the cylinder will not grease normally, and the piston rings will scratch them, and not slide.

Excess oil will simply burn, forming soot. She will pollute everything, including the piston and cylinder.

Failure gets into the valve, blocks their work, after which the motor will not start.

Will have to disassemble and clean the carburetor, or even put a new. Of course, you can try to wash the piston and the cylinder: it may be possible to bring them into working condition, but it is better not to bring them to.

The fuel mixture must be prepared with high quality and in strict proportion. The repair of a spoiled engine is expensive, about 70% of the price for a new gasoline trimmer for grass.

For the preparation of high.quality fuel mixture, I have a special container with a factory division of divisions in a set of trimmer for grass. Gasoline is neatly poured into it to the level of 500 ml, and then the oil to the required label.

An alternative method is the preparation of a fuel mixture with filling gasoline into a calibrated container, for example, a liter canister or a plastic bottle to a label, and an oil additive with a medical syringe according to its divisions.

The dosage with a syringe is more convenient, is considered the most popular way.

I recommend filling gasoline through a funnel with a narrow neck that has a filter: a metal mesh. protection against small garbage.

The prepared mixture should be well shaken and mixed until a uniform color appears. Only after that it can be poured into the tank.

If the mixture does not blame, then it will remain in the tank, and through the carburetor will enter the combustion chamber in portions with different ratios of gasoline and oil.

Fractions of clots of oil clog a candle. The motor stops, stalls, does not start. This is the fourth mistake of beginners.

It should be borne in mind that gasoline is hazardous. The risk of fire exists. Therefore, it is necessary to fill the mixture at a safe distance from the buildings, and in the case of the strait, which often happens to eliminate the causes of a possible fire. Violation of fire fighting measures. error

After pouring the fuel into the gas tank, the latter closes with a screw plug and the lack of leaks is checked. The trimmer for the grass is raised up so that the gasoline fills the cork. There should be no subterations from under the lid or from the fuel hoses.

Lack of such a check. an error can cause a fire.

There is one technical cunning that can cause a benzotrimer motor is not started due to the cessation of fuel supply. If you look carefully at the center of the traffic jam, then a round hole is clearly visible.

We turned Motokosa. Gasoline filled the cork, but does not flow through the hole: there is a sapphone inside. He is working.

On the inside, its design is clearly visible: a valve system of plastic and rubber is built.

In the usual state, the valve is pressed to the hole and the fuel does not flow. Когда бензомотор работает, то топливная смесь расходуется через карбюратор. A vacuum is created in the tank. The vacuum opens the valve of the saapon, the pressure is restored.

You should know the two consequences of a malfunction of the sapuna:

• Constantly open hole. fuel pours out of the tank during its inclinations (excess consumption and the probability of fire).
• Contamination or sticking of the valve channel is the reason that the lawn mower does not start or stalls.

Check the soundtress is easy: you need to blow it in both directions.

All about the gas tank cover, including the repair of the saapun, is shown in the video of Bogdan Shabanov.

3 additional advice associated with limited chemical resistance of a mixture of gasoline with oil:

• Do not create an excessive fuel supply. Use freshly prepared fuel mixture. In a maximum of a couple of weeks, she will lose her useful qualities;
• Prepare as much fuel as it will go to one mowing during the day. At the end of the work, drain the rest from the gas tank and burn the last drops from the fuel canal with a neglected engine;
• It is especially dangerous to leave the mixture in the gas tank for a long time. winter. In the spring, you will make sure that the engine does not start without cleaning the carburetor (gasoline evaporated, the oil thickened and glued the valve).

In more detail, the technology for eliminating these malfunctions shows in its video video “Chinese lawn mower is not started” Sergey Lesnik. Pay attention to the fuel filter.

To adjust the work of the carburetor allows a special screw, but it is not worth it to twist it without need: the factory adjustment is accurately exhibited. It is better for novice users to contact the service center.

Oleo-Mac Sparta 37 problems are not gaining momentum!

The usual work of braids with internal combustion and possibly disturbed due to the getting of the dirt in the exhaust channel or clogging of the muffler grid. There is such an inconsistency on the models of the older generation. Solve the issue of course by classical cleaning and removal of the anti.icing grid.

If the step.by.step method of searching for a malfunction did not give a result, and your braid for grass as before does not start or stalls, it is worth looking at the carburetor and the engine itself. The clogged carburetor will be the main reason, unbalanced operation of the tool. There are three main tasks here:

• Clogging of channels or nozzles. The entire aggregate is cleaned with special flushing or blown by a strong stream of air of high pressure from the compressor. Do not use needles and wire, so there are variations to be damaged by passing sections;
• Wear of the carburetor laying. Output is a change of laying out;
• Violation of density. To check this indicator, use a common domestic tonometer, replacing it with a deceased. Look for the testimony: if they do not change, our client remains perfectly, and since the pressure will begin to fall, it means that some part of the carburetor is faulty. Will have to find it and replace the latest.

If our client remains in order with the carburetor, then the gasoline trimmer for the grass may not be launched due to wear of the piston group. If chips are detected, scratches in other words of Zadirov, on the piston on another cylinder they should be replaced. Piston rings are subject to inseparable verification. A small piston owl when swaying the connecting rod shows that the time has come to change the rings. This function is best entrusted to the specialists of the service center.

So that the lawn mower is perfectly started and henceforth, it is necessary to provide it with excellent storage and operation conditions:

Oleo-Mac Sparta 25. The next repair of a seven.year.old lawn mower

• At one time, look closely behind the cooling system, painstakingly and fit clean the channels in the housing, additionally the starter ribs;
• If necessary, use solvents, kerosene and other cleaning products for cleaning;
• Do not clean the “hot” tool. let it cool;
• Be sure to make the requirements of the annotation for the operating mode, it is different to overheat the engine;
• If you do not plan to use the lawn mower in the near month, the fuel mixture from it must be drained, t. to. Over time, it breaks up into languid fractions, which will definitely score the channels of the carburetor;
• After draining fuel, let the trimmer work at idle until it stalls, this will help to completely remove the remains of the working consistency.

Before winter storage, take subsequent steps:

• Disassemble the braid for one hundred percent, wash and clean our client the details remain, which you can;
• Inspect the details for damage, if necessary, droop distortions, impulses, bent and any other malfunctions;
• Pour a sufficient amount of oil into the gearbox and clean the air filter;
• There is a partly option to disassemble the motor, wash, blow and smear what remains to our client mobile parts;
• If you want to be to lubricate the piston, you need to turn the candle, raise the piston with the last dead point by the starter, pour a small oil into the candle hole and scroll the crankshaft several times;
• If you store the lawn mower not in your house, wrap the engine with an oiled rag.

Remember, thorough compliance with the rules may be blurred that the lawn mower is badly starting over several seasons.

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);

Our service center takes only gasoline trimmers for OLEO-MAC grass for repair. We do not repair electric trimmers for grass!

Attention! Before contacting the service center!

We ask you to inform the manager of our company in advance: the exact model of equipment. If you need spare parts for a gasoline trimmer for Oleo-Mac grass, you need to know: the brand of your engine; engine model; type of; The code located at the installation site of the carburetor, the spark plugs or muffler. The engine code is indicated by a line consisting of 3 groups (in each line 6-signs without additional quotes and stars).

The knives are incorrectly adjusted

This can be seen on the uneven surface of the lawn. Before adjustment, it is necessary to turn off the lawn mower from the network and put on protective gloves.

The gap between the cylinder and knives should be uniform in all areas and not exceed the thickness of the office paper sheet. Even to regulate the gaps, the same paper is used. It is inserted between the cylinder and the knife, after which the drum rotates. It is necessary to adjust the knives until the paper is cut smoothly anywhere in the knife.

Let’s summarize

Having familiarized yourself with the information, we can conclude that with proper work with garden equipment and timely maintenance, most problems can be avoided. If the nuisance has nevertheless happened and the lawn mower does not work at full capacity, you can try to eliminate the breakdown on your own or contact the service center.

Malfunctions leading to improper operation of the chainsaw

There are a number of malfunctions that must be taken into account in diagnosis, t. to. They can lead to the interruptions of the saw.

• Damage to the crankshaft bearings. With worn crankshaft bearings, the appearance of a beating on the main shaft is inevitable, where the flywheel is attached. In such a situation, it is impossible to adjust the gap between the flywheel and the ignition coil, which entails interruptions in sparking, and unstable work of the chainsaw.
• Pollution of the pulse channel. The pulse channel serves to ensure the operation of the fuel pump, respectively, its pollution leads to improper operation of the pump, which will make it impossible to operate the saw (it will be launched and immediately stall).
• Wear of the CPG. As a rule, with increased wear of CPH, a decrease in compression in the chainsaw engine is observed, which is necessarily affecting its ability to develop momentum.
• Fuel and air filters pollution.

The lawn mower is not started after winter

In such cases, it is necessary to conduct maintenance of the unit. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean each node, rinse. Pour the filters with air. Pay attention to the quality and octane fuel number.

It must be taken into account that the products of such well.known companies as Stihl, Husgvarna and other brands will not work on a cheap octane number of gasoline. For them, suitable fuel from the AI ​​brand. 92 and higher with car gas stations and that, with well.proven ones, since gas stations are also bad gasoline. On the use of highly octane and high.quality gasoline, it will depend on how long the lawn mower will be used and how much it will last.

One more fact must be taken into account that with the long storage of diluted fuel mixture, it falls working qualities, which also leads to the consequences in which the lawn mower will not start. Therefore, it should be diluted with portions, that is, the amount of a mixture that is produced at a time. The operating instructions clearly describe and are given clarifications on the proportion of mixing gasoline and oil. Straighten compliance with the correct proportions will at least save you from several questions, why the lawn mower will not start and what to do in such cases.

The lawn mower starts and stalls. What to do?

There is a spark, and everything seems to be normal, but the lawn mower is not started, in such cases, you should check the air access valve into the fuel tank. Clogging of the valve leads to the creation of a vacuum in a tank, in which the carburetor does not receive gasoline, so the lawn mower will start, but then it will die out. To exclude this reason, you need to clean the valve and try to get a lawn mower with a not fully twisted tank traffic jam. 2. If at the same time the lawn mower is not started, you should remove and clean the fuel filter, as well as check all the parts of the carburetor, and then try to start. The lawn mower is not started again, the air filter is disconnected, try to get without it if the gas station has started to mean the reason in the air filter, replace it.

The loss of the spark entails a check of contacts and the correctness of the clearance between them, conducting the wire to the candle and the candle itself. A method of checking the spark. to unscrew the candle, connect the wire to it, attach the candle sideways to the casing of the engine and pull the lawn.mower as if starting the starter several times, while you need to look at the corner and contact of the candle, the spark should run between them. If there is no sparks, take a new candle to do the same procedure, if the spark is not traced, the problem in the wire or contacts means it, it is better to replace them.

How to install a Chinese.made saw. Setting instructions

To correctly adjust the carburetor carburetor, you first need to remember the factory settings of the machine, and then turn on the engine. In the future, you will have to leave it for several hours to accurately set your own parameters. Sometimes the work is carried out once after ten minutes of engine operation, but many Chinese models require special control.

• Events begin with downtime. Using adjusting screws, you need to achieve the systematic speed of the engine, so you must first allow it to work at low speeds. Deviation from the norm is the movement of the chain on the bus. In this case, adjust the extreme position of the extreme screws so that the chain remains motionless.
• Transition to the average speed. Sometimes the engine smokes at the same time. This defect can be eliminated by tightening the screw for supplying a thinner fuel mixture.

In this case, the smoke will disappear, but the engine speed will increase. Adjustments must be adjusted to the level when the engine rotates when pressed on a throttle, without a sharp jerk or interruption.

Before buying, we recommend reading a chainsaw for reliability and quality. Watch the video clearly:

In order for the chainsaw to work correctly, it is necessary to carry out thorough work on setting up the carburetor in strict accordance with their priority. If the device has any malfunctions, it is necessary to complete its complete disassembly on your own. In most cases, any details that have become unsuitable for use should be replaced.

There are no problems with the chainsaw when you constantly check the quality of the carburetor settings and take measures in a timely manner to improve its work.
