The lawn mower does not start: causes of breakdowns and do-it-yourself troubleshooting

The lawn mower stalls when you press the gas, how to fix the breakdown

The reasons why motokosa stalls

- there can be a huge number, we offer the most common ones, and we hope that you will find yours, and, of course, eliminate it. So, one of the situations is the clogging of the air damper, the hole behind which the fuel is sprayed. If something gets into it, then it can most often be quickly and easily removed. This is the simplest reason, like a clogged filter. It must be washed in a solvent, and then blown well with compressed air. If it cannot be repaired, then order a new one in spare parts from the KosiKos store.

Similarly, when you press the gas, the tool stalls because the drive is clogged. The following option is also possible: the fuel is not supplied in full, so you need to check or replace the fuel filter. Other possible reasons for a stalled lawn mower when you give it gas include:

1. Crankshaft seals suck in air;
2. A spacer that is between the carburetor and the cylinder in a "problem" situation;

To all these reasons for which the mechanism stalls when gas is added, we will add some useful recommendations for handling the scythe. First of all, before starting work with any equipment, you need to read the instructions. In this case, the consistency of gasoline and oil plays an important role.

In the full-fledged work of any instrument, the coordinated work of all its components plays an important role. And if in one it is, then in the other there is a piston or a carburetor. Owners of lawn mowers who want to use their tools to their full potential need to understand that under a load for which the capabilities of the machine are not designed, the entire mechanism or its individual parts may simply break. Therefore, only competent and moderate operation presupposes long-term productive work of any gasoline-powered tool.

Trimmer stalls at idle - causes and solutions

To common situations, why trimmer stalls

or motokosa, it is worth attributing his work at idle. Let's jump right into the reasons:

heating of the gearbox and a decrease in speed on the drum as a result of the fact that the gasoline solution was not prepared quite correctly. Required proportion 1:4;
carburetor contamination;
clogged throttle;
when the damper is opened (if such an experiment was carried out), the air flow makes the mixture "poor";
carburetor adjustment;
clogged air filter;

An insufficient amount of fuel that is needed for the operation of a gas tool will entail a situation where, at high speeds, with an increase, the trimmer works, but stalls at idle. In a situation with a carburetor, the device will stall on a cold start and “hot”

For any user of a lawn mower - a professional and an amateur, it is important to understand that any malfunction of the tool may depend on a small part flying off, fastening or clogging, as well as on a global breakdown of an important part of the mechanism.

A novice and an experienced owner may encounter the problem of a stalled lawn mower, situations arise with used and completely new braids, and which ones we will deal with in this article. So, the tool can stall under load, immediately after starting, that is, it starts and stalls, when the entire mechanism is heated, at high speeds, or even does not gain momentum and stalls. In all these cases, in fact, the same systems, elements, nodes are involved, but the breakdown or malfunction of each of them, or rather, the nuances, cause an individual situation, which was voiced above. Answer to each user's question: why motokosa stalls

, you will only get on our website in the news articles section.

To fully understand your individual situation, carefully read the signs and accompanying nuances at the moment the scythe stalls, and then it will be easier for you to find a way out and quickly solve the problem.If you need certain ones, then you can do it in bulk, and the best petrol tool store in Ukraine, Benzo Zip, will allow you to do it at a low price.

Proper care of your chainsaw

There are no unnecessary phrases in the operating instructions, everything that is offered is aimed at the smooth operation of the gasoline pump. Cleaning of all parts after each cycle of work facilitates the removal of uncured residues and dirt. Clean only chilled parts. This method contributes to the quality of air cooling of the engine and gearbox.

When storing equipment for the winter, inspect, lubricate the gearbox and piston system, wrap the entire saw in an oiled rag and store it in a dry place.

It is impossible, dangerous for the tool and the health of the mower, to use a metal cable instead of a fishing line. It cuts more efficiently, but the load on the gear and motor is increased. A worn piece of wire flies at the speed of a bullet during detachment. Efficient mowing can lead to rapid wear of the engine piston group. For greater mowing efficiency, it is proposed to use an asterisk line profile.

While caring for a personal plot, sometimes people have to deal with the fact that their lawn mower does not start. There are several reasons for the failure of this tool.

Motokosa does not start - reasons

Improper storage, a long break in operation, untimely maintenance and other factors lead to the fact that the lawn mower may stop starting.

Diagnosing the causes should begin with checking the main components - the fuel tank, candles and candle channel, air and fuel filters, breather, exhaust channel. Most often, problems are associated with one of these nodes, and a thorough examination of them will help determine why the lawn mower does not start.

If you use low-quality fuel (below AI-92), this can lead to a breakdown of the cylinder-piston system, the repair of which will result in about a third of the cost

In addition, it is important to follow the correct ratio of gasoline and oil, as indicated in the owner's manual for your particular model.

The operation of the engine may be hindered by contamination of the fuel filter. If this problem is found, the filter must be replaced. It doesn't hurt to check the air filter as well. If it becomes dirty, it must be dismantled, washed in water with detergents, dried, lubricated in oil and put back in place. Spark plugs that show no signs of life should be replaced with new ones.

Sometimes the lawnmower starts fine, but then stalls. This is mainly due to incorrect carburetor setting or misalignment. It is possible to determine that this is the reason by the vibrations that are noticeable during operation. You need to adjust the fuel supply adjustment by following the instructions for the tool.

Motokosa does not start well when hot

When the lawn mower worked properly, and after a short break does not want to start again, you need to press the gas trigger and pull the starter cord sharply several times in a row until the engine starts and only then release the gas trigger.

Lawn mower won't start when cold

On the contrary, it is not recommended to press the gas when starting a cold lawn mower.It is necessary to tilt the lawn mower so that the air filter is at the top and press the suction button 5-6 times, then set the function switch lever to the “Start” position and pull the cord several times until the engine starts. After a few seconds of scythe operation, the launch system can be turned off.

What to do, if fuel pump won't start ? In this article, we will look at the main causes of this breakdown.

Most often, the lawn mower refuses to start because the fuel fills the spark plug. This may be due to the fact that worn nozzles supply too much fuel to the combustion chamber, and its excess fills the candle, which is why it cannot generate a spark. If the plug is always wet, then this may indicate wear on the gaskets, due to which the flowing oil prevents the formation of a spark. If the candle is dry, but the lawnmower still does not start, then first you should replace the candle itself.

Another common reason is that a 4-stroke lawn mower refuses to start “hot”. Here we can recommend a simple test: pull the trigger, pull the starter cord several times. If after that the engine still does not start, then your tool needs more detailed diagnostics with subsequent specialized repairs.

Useful information for those who do not start the trimmer after winter

Why the trimmer does not start after wintering
? What are the main causes of this problem?

1. The problem is last year's fuel.

The gas trimmer may not start due to the fact that last year's fuel remained in the tank, which, simply put, ran out. Two signs can testify to this: the candle is dry and there is a spark.To fix this problem, you just need to change the fuel.

In addition, a gasoline trimmer starts up a little differently after winter. Open the choke and pump some gasoline into the carburetor, and then pull the handle back until you feel some resistance. After that, you can start.

Air filter problem.

Long periods of inactivity may clog the air filter. Evidence of this may be the start "hot", after which the trimmer immediately stalls. Perhaps, in the cold season, the filter managed to clog with dust. There are two options here: first you need to clean it, and if this does not help, then you need to purchase a new filter.

In general, such a conversation should begin with the fact that after buying a garden petrol tool, it would be better to first read the instructions attached to it. Then many problems could have been avoided. But since this happened, the gasoline trimmer does not start, then we must look for sources of inoperability. And in this article we will consider the main reasons why the trimmer does not start using the Elitech T750 model as an example, and we will also tell you general recommendations for using such a tool.

You should start with the banal! Let's figure out how to start a gas trimmer correctly. It may be that the reason lies precisely here.

First you need to bring the red toggle switch on the trimmer bar to the “I” position. This means power on. Then you need to switch the fuel supply lever on the carburetor and use the fuel "suction" button (looks like a pipette, located on the carburetor). This is necessary to supply gasoline to the engine. Return the fuel supply lever to its original position. Finally, pull the starter handle sharply towards you. The trimmer should work. Try a few times if it doesn't work the first time. If after such manipulations the situation has not changed and the gas trimmer does not start, then you should first inspect it yourself before taking it to a service center. There are two main reasons why a garden trimmer won't start:

1. Violation of the supply chain.
2. No fuel.

The second reason why a garden tool does not work is that the fuel has run out. On the Elinech T750, the fuel tank is located near the motor, but on most trimmers it is also located there. We unscrew the cap from the tank and fill it with gasoline (the best option is AI-92, it is inexpensive and does not clog the carburetor like AI-76). Do not forget to add special oil for engines to the tank, 50 grams per gas tank is enough, without it the engine will start to “sneeze” and quickly become unusable. After we close the tank with a cap, wipe the surface of the trimmer and our hands with a dry cloth. We also do the above manipulations to turn on the garden tool.

If the gas trimmer still does not start, then it makes sense to send it in for repair. And the reason for this decision is simple - if you do not have the appropriate skills, repairing equipment is almost impossible.

In order for the tool to serve as long as possible and there are no such problems, you should first of all read the instruction manual for the trimmer

Also pay special attention to the time the engine is running at the trimmer - take a short break every 15 minutes of work and, finally, properly care for the tool, wipe it after work, lubricate it with graphite grease. By following such simple rules, you can significantly increase the life of the tool and it is quite possible that you will not have to look for reasons why the gas trimmer does not start.

Why not start trimmer
petrol? Prerequisites and their elimination

Soon petrol trimmer
acquired the status of the 1st of the main tools in the arsenal of summer residents. And this is logical, because a motorized scythe allows you to quickly put your garden in order. But from time to time it happens that the trimmer does not start on hot and even on cool. In such situations, it is necessary to independently determine the cause of the malfunction. Let's find out what to do if not start up
trimmer. The prerequisites that more often lead to such troubles will be considered further.

Solutions

It is best to start repairing lawn mowers with a phased check of the main components. The first thing to check is the fuel in the tank, as well as the presence of lubricants on the main components of the tool.

It is also important to know what quality and what proportion of the fuel and oil used. If something is wrong, then the piston system may fail, and its replacement is expensive

Next, it is worth evaluating the serviceability and performance of the spark plugs. The result is judged by the presence of a spark when there is contact with the tool body. If the fault is in the candle, then you need to remove the voltage wire from it.

In case of contamination, it is recommended to replace it with a new one and dry the candle channel. This is also done if there are cracks or chips on the candle body. The gap between the electrodes is set to 0.6 mm. Clamping a new candle is also done with a special key. At the end, a voltage wire must be connected to it.

It will be useful to inspect the filters, both fuel and air. If the blockages are strong, then replacing them will be the best solution. You can try washing the air filter with water and detergent, and then dry it. It is also sometimes soaked in gasoline

After drying and installation, it is important to moisten the filter with oil, which is used in a mixture with fuel.

It is very easy to fix the problem in the form of a stalling lawn mower immediately after starting - just adjust the carburetor according to the scheme given in the documentation. Sometimes it is necessary to loosen the valves of the carburetor in order to facilitate the flow of mixture into it.

Sometimes the brush cutter stalls due to the intake of a large amount of air. In this case, it is necessary to increase the engine speed in order to release it. Also be sure to check the fuel hose for possible damage. If necessary, it is replaced with a new one.

It is important to keep the gearbox clean, and its gears should always be treated with a special lubricant. It is worth noting that it is not always possible to repair the gearbox and starter on your own, therefore it is more expedient to replace them with new ones if these nodes break down.

When reducing engine power, you should pay attention to the exhaust muffler, or rather, to the grid in it. It can become clogged due to soot coming from burnt oil.

This problem is solved by cleaning the grid.This can be done using a small brush with wire or nylon bristles and compressed air.

The clutch in lawn mowers can break due to worn pads or a broken spring. In both cases, the failed parts are replaced. Sometimes the clutch becomes unusable, it can also be replaced with a new one. Moreover, both fully assembled couplings and individual elements for them (washer, drum, etc.) are on sale.

Determination of the causes of the malfunction

If the trimmer engine does not start or stalls immediately after starting, when the gearbox overheats or during the operation of the device, extraneous noises are heard and vibration is clearly felt, it is important to make a visual inspection and identify a non-working unit

To optimize the preparatory measures before repair, a simple diagnosis should be carried out and a step-by-step check should be made:

• the presence of fuel in the tank and lubrication in the main components;
• serviceability of the spark plug and its performance;
• cleanliness of the fuel and air filter of the lawn mower;
• clogging of the outlet channel and breather of the device;
• the quality of the fuels and lubricants used.

To determine the functional performance of the ignition of the lawn mower, it is necessary to determine whether the candle is working by testing the appearance of a spark when it comes into contact with the body of the functional device.

The spark plug itself can be replaced with a new one, after drying the candle channel, if necessary, the old element is also dried, cleaned with special tools and returned to its place.

Briefly about engine repair

Problems in the engine begin after a few years of proper operation from the wear of components or suddenly when the trimmer is used incorrectly. Unfortunately, they regret improper operation when they repair gasoline trimmers with their own hands after an engine breakdown. And this happens in cases where the dosage of oil in the fuel is not observed or the device works to a terrible overheating. Overheating may cause crankshaft jamming, destruction of piston rings, or complete burnout of the piston. In order to perform a piston revision, it is enough to remove the cylinder head, from under which the piston will appear, clearly reflecting the state of its working surface. The rings themselves do not peek out of the cylinder, so it does not matter whether to change the rings or the piston, in both cases you will have to remove the cylinder. When repairing gasoline trimmers with your own hands, it is worth remembering the fragility that can easily break in the absence of experience. The piston itself is not too difficult to install on the crankshaft. The main thing when repairing an engine is to assemble everything in the same way as it was before disassembly, and then everything will work again.

Trimmer repair is necessary when the device does not turn on or does not function properly. All owners of private houses and suburban areas are familiar with the problem of excessive vegetation, which is sometimes difficult to get rid of. As you know, progress does not stand in one place and new developments and useful inventions appear in all areas. This also affected agriculture. You no longer need to mow the grass with old inconvenient devices, modern gas mowers have come to the rescue, which are able to get rid of vegetation in the most inaccessible places.

With a petrol trimmer, you can mow the grass even during cloudy weather. It is very simple to take care of a personal plot with the help of this unit, and any adult man will be able to cope with this activity.

Despite their versatility, like any technique, trimmers tend to break and fail.

Not every person can do the repair of a lawn mower with their own hands, because this requires the skills of repairing electrical appliances, but today we will try to figure out how to start a trimmer without a starter and how you can debug its work with your own hands.

Malfunctions of lawn mowers and ways to eliminate them

Any type of lawn mower has a hollow rod, in which a connecting cable is placed between the motor shaft and the lower gearbox, which transmits rotation to a tool with cutting equipment. In the upper part there is a carburetor and a motor, in the lower part there is a gearbox and a working tool covered with a casing. In the middle part there is a cross handle when the control buttons are placed. To unload the hands, there is an unloading belt that holds the bar with the operator's torso.

In the process of choosing a lawn mower, a device with a two-stroke engine is better than a four-stroke one. A two-stroke motor is more maneuverable and easier to repair. With a four-stroke unit, the vibration level is lower.

They follow this, the repair of lawn mowers is to eliminate defects;

• the engine does not start;
• the cutting mechanism does not develop;
• the engine stalls;
• the gearbox heats up;
• a third-party knock is heard, a powerful vibration of the rod.

KEY DOP

While troubleshooting, it is necessary to diagnose, find a non-working node.

It is important to know the lubrication points of the tool. Constant care, cleaning the device after work will extend its life.Before starting work, you need to tighten the mounting bolts, prepare fuel and fill the tank.
