Trimmer does not start, candle is dry

Gasoline trimmer won’t start. reasons

trimmer, does, start, candle

Many gardening tools are useful and effective, but there are times when the equipment refuses to work. Among them was a trimmer that can mow both a miniature lawn and huge lawns.

Reasons why the petrol trimmer won’t start

There are various reasons why the petrol trimmer won’t start:

  • The most common reason for a breakdown lies in the wrong choice of fuel. Often, overly economical users of the device fill the tank with something dubious, but not fuel with a normal octane number. Low-quality fuel that has been kept in a plastic canister for a long time has a terrifying effect. The device, which has lost its functionality for this reason, is sent to a complete bulkhead of the mechanism.
  • There is another common situation where the petrol trimmer starts and stalls. The problem could be the spark plug or air filter. In the first case, after inspection, it will be found that the candle is “thrown”. This happens even if it has been recently wiped and dried. If everything is in order with the candle, then it is worth inspecting the air filter. Most often, it turns out to be oiled and needs to be replaced. If the device still refuses to start, then the problem lies either in a faulty ignition coil or in a clogged muffler.
  • The device can deteriorate not only due to poor-quality fuel, but also due to improper handling. For example, the fuel is checked, there is a spark, but the device will not start. The reason may be a candle filled with gasoline. To correct the situation, you just need to unscrew the candle, wipe it, dry it and check for operability.
  • Sometimes there is such a situation. the gasoline trimmer does not start when the candle is dry. Then it is necessary to lubricate the threaded connection with gasoline. It should be slightly damp, otherwise nothing will catch on fire.
  • Often, the owners of the device find themselves in a situation where the gasoline trimmer does not start well when hot. Some experts claim that the problem lies in the ignition coil. Therefore, it must be changed, and the device will work. But the problem may be overheating of the engine, especially if a reinforced circular saw-type knife was attached to the device. To avoid such situations, you should carefully study the instructions, which specifically describe what types of discs can be installed.

The reasons when a new gasoline trimmer won’t start can be the most commonplace, for example, inability to use the device. If the user stores it correctly, uses high-quality fuel and does not leave gasoline in the trimmer, then the unit will serve faithfully for a long time.

Filter check

Another common reason the trimmer won’t start is if there is a blockage in the filter area. To confirm the guess, it is enough to dismantle the indicated block and try to start the unit without it. If the trimmer engine starts, most likely you will have to replace the air filter or at least thoroughly purge the old one. If there is abundant dirt on the surface of the filter element, a new mesh must be used. When resorting to such actions, do not leave the suction pipe completely without a filter. After all, haste in this case can lead to the need to repair the entire piston group of the engine unit.

Diagnostics of the candle channel

What to do if the used fuel mixture is in good order, but the petrol trimmer still won’t start? The reasons for the failure of the mechanism may lie in the excessive moistening of the candle channel. To diagnose and fix the problem, you must do the following:

  • Unscrew the candle. Wipe it thoroughly and then dry it.
  • Drain excess fuel in the chamber through the appropriate plug hole.
  • Clean old spark plug if there is carbon deposits on its surface. To cope with the task will allow the use of a regular ladies’ nail file or a file.
  • When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the gap.
  • Assemble the functional block back.
  • Try to start the trimmer.

It is recommended to dry the candle channel for at least half an hour. However, in no case should you resort to calcining its elements. After all, heating the spark plug can lead to its final damage. What to do if the function block was serviced in accordance with the above recommendations, but the trimmer does not start, there is still a spark? In this case, it is worth treating the threaded connection with gasoline. The latter does not need to be abundantly impregnated with fuel. It should only be slightly damp. Such actions should be taken to ensure ignition. After all, no matter how strong a spark the candle gives, there will simply be nothing to ignite in an absolutely dry chamber.

If, even in this case, the trimmer does not start, it is worth assessing the quality of the contact between the high-voltage wire and the candle. In the absence of a spark (if there is a reliable connection between these elements), most likely, the problem is caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of wizards who will reinstall the node.

Off-season petrol trimmer storage tips

When storing the trimmer, it is worth filling the gearbox with enough oil. Then you need to clean the air filter, partially disassemble, blow out and rinse the engine of the unit. After drying all mechanisms, the moving elements should be lubricated. To process the piston system with oils, you must first remove the spark plug. Then you need to move the piston to the extreme position, then pour a small amount of oil into the spark plug hole and rotate the crankshaft. If you do not plan to store the petrol trimmer in the off-season in the house, it is recommended to tightly wrap the engine of the unit with an oiled rag. This will avoid the development of corrosion on the surface of important parts of the mechanism.

How to prevent sudden breakage during trimmer operation?

In order for the unit to always be in a functional state, it is worth following a few simple rules:

  • Conduct a timely, regular technical inspection of the main mechanical components of the device.
  • Fill the trimmer with only fresh fuel, the quality and origin of which is beyond doubt.
  • After each use of the tool, check whether oxides and carbon deposits have formed on the surface of the ignition system components.
  • Avoid heavy load on the trimmer during work.

In order for the unit to remain in working order, it is necessary to properly prepare it for storage in the winter. First of all, you should completely disassemble the instrument, and then flush and clean the constituent elements. It is also important to inspect the functional blocks for damage, if necessary, eliminating the deformation of parts, all kinds of distortions, gusts of materials.

Outlet duct diagnostics

Stable trimmer performance can be compromised by build-up of dirt in the exhaust duct or blockage in the muffler mesh. This problem most often occurs during the operation of older generation trimmer models. The issue of dismantling the anti-spark grid and cleaning it is being resolved.

Why won’t the petrol trimmer start? Causes and their elimination

Recently, the gasoline trimmer has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because the motorized scythe allows you to quickly put your personal plot in order. However, it sometimes happens that the trimmer does not start hot or even cold. In such situations, you have to independently determine the cause of the malfunction. Let’s figure out what to do if the trimmer won’t start. The reasons that most often lead to such troubles will be discussed below.

Checking the fuel mixture

Let’s say your trimmer won’t start. In this case, the first step is to check if there is enough fuel in the tank, and also to assess the quality of the fuel mixture. It is necessary to refuel the motorized unit with exclusively high-quality gasoline. It is recommended to use fuel, the grade of which is not lower than AI-95. Filling the trimmer with fuel of unknown origin not purchased from a gas station can cause frequent tool malfunctions. This can cause damage to the piston-cylinder system. In this case, repairs often exceed the cost of the device itself.

How to Fix a Trimmer That Won’t Start!

Why won’t the petrol trimmer start? Improper preparation of the fuel mixture, which consists of oil and gasoline, can also lead to this. The proportions in which these components are connected are indicated by the manufacturers in the trimmer instruction manual. It is highly discouraged to prepare a fuel mixture in large volumes, that is, for the future. Indeed, with long-term savings, there is a loss of the defining properties of the substance. Therefore, if the trimmer does not start, it is worth draining the old fuel and using a freshly prepared fuel mixture.

Breather cleaning

Often, the engine of branded trim models stalls as a result of a clogged breather. The main task of the specified component is to equalize the pressure in the fuel tank. In case of contamination of the unit, a vacuum is formed here, which significantly complicates the supply of fuel. The problem can be eliminated by cleaning the breather with a regular sewing needle.

Breather

The breather is a non-return valve designed to equalize the pressure in the gas tank. If it is clogged and does not allow air to pass towards the tank, then a vacuum forms inside the fuel container, and the fuel stops flowing into the carburetor. To check if the valve is working, remove the hose that goes from the reservoir to the carburetor. If gasoline does not flow out of the tank, it means that the breather is clogged.

Trimmer users often ask themselves: Where is the breather? This valve is usually located in the gas cap and looks like the following figure.

Cleaning the breather is very simple: disassemble the valve and rinse all of its components. On some mowers, this valve may be located directly on the fuel tank. It will not be possible to find it right away, since it is hidden from view under the starter housing. Such a breather is cleaned with a regular needle.

Fuel tank (fuel quality)

Remember that it is always necessary to check the availability and quality of fuel before starting the unit. In this case, you should not be greedy and save, as well as “be smart” about the amount of added oil. Everything must be done according to the manual attached to the device, since if the piston group fails, its replacement will cost about 70% of the total cost of the trimmer. Fill in fuel on the basis that you will completely use it up when performing work. The gasoline remaining in the tank loses its properties after a while and can harm the engine. Therefore, do not prepare the mixture for future use and in large quantities. If the lawn mower does not start well, try draining the “old” fuel from the tank and refueling it with fresh mixture.

Important! Filling the device with fuel, the origin of which is unknown, is fraught with negative consequences. Gasoline must be of high quality, purchased at a gas station, and its brand must be at least AI-95.

Candle and candle channel

So you’ve changed the fuel, but nothing has changed, and the trimmer still won’t start. In this case, it is worth checking the candle channel: does it cover it with a combustible mixture. Often users turn the choke to the “OFF” position when starting, and when the engine starts, they do not turn it to the “ON” position, after which it stalls. Further, an attempt to restart the internal combustion engine leads to the fact that gasoline fills the candle, and the start becomes impossible. To diagnose and fix a possible problem in this node, do the following.

  • It is necessary to unscrew the spark plug, wipe it well and dry it. When installing the spark plug into the internal combustion engine cylinder, it must be dry.
  • Drain the accumulated fuel from the combustion chamber. This is done through the hole from which you unscrewed the candle.
  • If there is carbon deposits on the electrodes of the candle, it must be removed either with a thin file or with a nail file.
  • Do not forget to set the gap between its electrodes before installing the part. The gap on the spark plug should be 1 mm. You can use a coin as a probe to check the gap.
  • Next, assemble the unit, read the starting instructions and try to start the engine again.

If the internal combustion engine does not start, then you will need to check the spark. For this:

  • unscrew the candle;
  • put the cap of the high-voltage wire on it;
  • touch its metal part to the cylinder body (to ensure contact, you can insert a pipe wrench) as shown in the figure below;
  • pull the starter cord until the engine rotates a few times.

Normally, every time the piston rolls between the electrodes of the plug, a spark should slip. If there is a spark, then the reason that the internal combustion engine does not start must be looked for in other nodes of the device.

For a better understanding of the process of how to test a candle for the presence of a spark, you can use this video, where the test is shown using the example of the Soyuz lawn mowers.

If there is no spark, then first check the cable connecting the candle to the coil. perhaps the reason is in it. You can call him using a tester. If an open circuit is detected, the high-voltage wire will need to be replaced.

Also, the reason for the missing spark may be a malfunction of the ignition coil (magneto). The picture below shows what the coil (magneto) looks like from a Patriot petrol trimmer (Patriot).

To exclude a malfunction, you will need to check the trimmer magneto with a tester, namely, its primary and secondary windings. On the primary winding, the resistance should be between 0.4 and 2.0 ohms. If the device shows 0, this means that a short circuit has occurred in the winding, and if infinity is a clear sign of an open circuit. The resistance on the secondary winding must be between 6 and 8 kOhm.

On some coils, it can reach 15 kOhm.

Breakage of petrol trimmers

Typical breakdowns of a gasoline trimmer, which the owners of this unit most often encounter, are as follows:

  • engine breakdown;
  • carburetor problems;
  • fuel supply problems;
  • muffler malfunction;
  • breakdown of the gearbox;
  • the starter has broken;
  • air filter problems;
  • gas tank breather clogged.

Electric trimmer vibrates

Many mower users have noticed that some time after the start of the machine, it begins to vibrate strongly. On some trimmers, mainly in more expensive models, an anti-vibration system is installed in the form of shock absorbers located between the engine and the boom. But in some cases, even she does not save from strong vibration. The reason that a strong vibration appears in the trimmer may be a small amount or a complete absence of lubrication on a rigid or flexible shaft located inside the apparatus rod.

Rigid shaft lubrication is changed as follows:

  • unscrew the gearbox located at the bottom of the rod;
  • after removing the gearbox, you will see the end of the shaft, which must be pulled to remove the part;
  • after removing the shaft, it must be abundantly lubricated with a special grease “Shrus-4” or the usual one. “Litol-24”;
  • apply a small amount of grease to the shaft and spread it evenly along the entire length of the part, including the splines at the ends of the rod (if they work, the shaft will have to be replaced);
  • after lubrication, insert the shaft back into the rod and put the gearbox in its original place.

The flexible shaft is lubricated as follows:

  • unscrew and remove the mowing head;
  • remove the rod from the electric motor by unscrewing a couple of bolts;
  • pull the flexible cable out of the rod;
  • lubricate the cable with grease along the entire length.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the rod, after which, as it moves inside the pipe, you should apply lubricant to the part and distribute it evenly over the surface. Then insert the flexible shaft rod into the electric motor and secure it.

In the case when the lubrication did not help, and the vibration continues to appear, you will need to change the flexible shaft.

Garlic can be propagated not only by cloves, but also by air bulbs that ripen in the arrows. The seed method allows not only to save seed, but also to completely preserve the varietal characteristics of the mother plant. The main thing is to choose the right time for collecting seeds.

Modern lawn mowing technology allows you to care for the local area with minimal effort. Of course, provided that the garden tool is used correctly. And perhaps the most important question in working with garden trimmers is how to properly fill the line.

Nasturtium is a beautiful and useful flower that is often found in the gardens of domestic summer residents. One of the advantages of this flower is its simplicity and ease of reproduction. Once you have bought nasturtium seeds once, you can easily prepare them yourself for all subsequent years.

Technique in the hands of an attentive and competent person works many times longer. If you decide to get a grass trimmer, be sure to study the question of mixing gasoline with oil. This will avoid breakage and extend the life of your purchase.

Malfunctioning electrical trim tabs

Since the device of an electric mower is much simpler than a motor trimmer, there are few reasons for its failure.

It should be noted that it is better to entrust the elimination of some of them to a specialist.

Basically, the trimmer stops working normally in the following cases:

  • malfunction of the electrical cable;
  • the control button is faulty;
  • burned out motor stator winding;
  • breakage of contact connections on the engine.

Petrol trimmer won’t start. 10 possible reasons

Before attempting to adjust the operation of the tool yourself, carefully read the instruction manual for its operation. Perhaps the information contained in it will push you to one or another thought. Otherwise, you will have to look for the cause of the malfunction by the selection method. It can be one of the following:

  • The toggle switch on the boom is not in the “On” position. This is one of the basic steps, but sometimes beginners forget to turn on the tool before launching it.
  • Lack of fuel in the tank also belongs to such errors. If you run out of fuel and you forgot about it, just fill the tank (usually located near the engine) with AI-92 gasoline.
  • Lack, inappropriate mixture or proportion of engine oil. Ideally, no more than 50 g of oil should be added regularly. This will provide additional lubrication and keep your trimmer motor running. Also keep in mind that there are different types of oil (“synthetics”, “semisynthetics”, “mineral water”). they all have a different effect on the operation of the mechanism.
  • If the trimmer mower does not start after winter, drain the remaining fuel in the gas tank and replace it with fresh fuel. This is especially true for small, low power trimmers with small motors that are sensitive to poor quality mix. In addition, during the winter, sediment may form at the bottom of the gas tank, due to which problems arise with the operation of the device.
  • Excessive fuel pumping can also be one of the reasons that the trimmer stalled and will not start. When the choke is closed, the spark plug is flooded with fuel. It should be unscrewed and dried, and then inserted into its place and try to start the engine while holding the gas trigger. It is advisable to check it before that there is a spark between the electrodes. If there is no spark, the spark plug should be replaced.
  • Filter problems. If your trimmer does not start well, remove the air filter and start the tool without it. If everything worked out, the filter should be replaced with a new one. As an option. thoroughly clean and blow out the old one, however, sooner or later you will have to make a replacement.
  • Trimmer stalled and won’t start? Try to clean the so-called breather. an element designed to equalize the pressure in the gas tank. Cleaning can be done with a regular long needle. A clogged breather is often the cause of a malfunction.
  • The knives have been removed from the machine. some models will not work under this condition.
  • Violation of tightness. You can check this with a pressure gauge. If the pressure starts to drop, you should determine which part of the carburetor is faulty. Most often the carburetor gasket wears out.
  • Sometimes, after a long period of operation, you will notice that the trimmer is overheated and will not start. First, you should know to take breaks. The amount of continuous operation time recommended for this model should be indicated in the instructions. Also, the problem of overheating may lie in a faulty ignition coil or in the air cooling system, which prevents overheating.

If none of these steps worked, you should contact a repair shop or service center.

Perhaps, every summer resident who has a trimmer, at least once in his life, faced a situation when the tool staged a “strike”. For example, it started badly or began to stall when you press the gas. What to do in the latter case, the article will tell.

In the course of construction work, there are situations when it is necessary to cut sheet metal. To cope with this problem will help such a convenient tool as lever scissors, designed for curly and straight cutting. Their characteristics are described in this article.

Typically, conventional garden grass trimmers are used in conjunction with a line. But if you need to cut young growth of shrubs or trees or very tough grass, you cannot do without a disc trimmer. Read about trimmer discs in the article.

Many novice seamstresses pay a lot of attention to the choice of a sewing machine, thread and fabric, and at the same time completely forget about scissors. But high-quality scissors are among the basic tools of a tailor. Our article will tell you more about them.

Breather

The breather is a non-return valve that is designed to equalize the pressure in the gas tank.

If it is clogged and does not allow air to pass towards the tank, then a vacuum forms inside the fuel container, and the fuel ceases to flow into the carburetor.

To check if the valve is working, remove the hose that goes from the reservoir to the carburetor. If gasoline does not flow out of the tank, it means that the breather is clogged.

Trimmer users often ask themselves: Where is the breather? This valve is usually located in the gas cap and looks like the following figure.

the lawn mower will not start hot. pull the gas trigger and pull the cord abruptly several times until the engine starts, then pull the trigger. Will not start. specialized repair required.

Checking the ignition system, if the lawn mower does not start, is carried out sequentially:

  • clean the removed candle from carbon deposits and dirt, dry it, set a gap of 1 mm;
  • connect to a high-voltage wire and check for a spark by pulling the starter several times;
  • in the absence of a spark, check the high-voltage wire for integrity;
  • replace the candle;
  • dry the candle channel;
  • at the same time the operation of the ignition coil is checked, it is faulty if the working plug does not spark.

It is in the event of a malfunction of the ignition coil of the lawn mower does not start up hot, stalls, works intermittently.

Cleaning or replacing the air and fuel filter will ensure the proper consumption of ingredients entering the carburetor. The air filter can be washed in soapy water or replaced. If nylon fabric is used, it is washed, the porous felt filler is replaced. Change the fuel filter carefully without leaving the intake manifold open. Whether it is necessary to replace the air filter can be determined if the engine starts with the air cleaner removed. Is it necessary to change the grid on the fuel supply, if the lawn mower does not start, a dry candle will tell.

Breather, gas tank air inlet. The lawn mower will not start or The reason for the malfunction is the lawn mower will not start hot. If it becomes clogged, a vacuum is created in the tank and the mixture does not enter the carburetor. The hole can be blown out with air or cleaned with a needle. Clean the exhaust duct, remove the anti-spark screen of the muffler.

Troubleshooting

All the reasons why the lawn mower does not start can be systematized according to the specifics of the operation of individual units. In the service center, malfunctions are systematized:

  • motor malfunction (piston wear, bearing malfunction, crankcase crack);
  • malfunction of the fuel consistency supply. clogged pores of the air filter or carburetor malfunction;
  • the ignition system does not work;
  • malfunction of the mechanical nature. leaking hoses, broken wires under the braid, ruptured pipes.

the lawn mower cannot work for a long time. The gearbox and engine will overheat. Mows can be less than 15 = 20 minutes, taking a five minute break. On a hot afternoon, the operating time is cut in half. When mowing weeds, sedges, the working time must be reduced.

If the launch fails, we begin to find the reason for the failure:

  • check the quality of fuel;
  • make sure that the candle is working and the candle channel is clean;
  • check the cleanliness of the air filter;
  • make sure the fuel filter is not clogged;
  • check the cleanliness of the breather;
  • clean the outlet.

complex causes will be found during the diagnosis of malfunctions leading to overhaul of the carburetor. Such reasons include clogging of the internal channels of the carburetor, wear of the gasket on it and a violation of the tightness of the internal halls with a loss of vacuum. Do-it-yourself lawn mowers repair, if it won’t start, will take patience.

Why the lawn mower won’t start. troubleshooting

Caring for the personal plot, summer residents periodically encounter the fact that the lawn mower does not start. There are many reasons for tool failure. To correctly diagnose the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its individual parts.

Since the gasoline trimmer is a complex device, it is necessary to carefully study the operating instructions before starting work. Very often they simply ignore her, or get to know her superficially.

As a result, when the tool stalls or refuses to start, the question arises. “Why won’t the lawn mower start?” A long seasonal break in work, improper storage and untimely maintenance of the trimmer will cause a lot of trouble to the summer resident, to eliminate the reasons.
