Petrol hooter trimmer won’t start

Petrol trimmer won’t start? Elitech T750 Reasons and Solutions

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

You should start with the banal! Let’s figure out how to properly start the gasoline trimmer. It may be that the reason lies precisely here.

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

• Power circuit breakdown.
• No fuel.

• Let’s start with ignition problems. In most cases, it is caused by the need to change the spark plug in the engine. This is done like this:
• First of all, we must take care of the safety measures, making sure that the trimmer is turned off. We bring the above toggle switch to the “STOP” position.
• Then we remove the rubber protection from the spark plug and the wiring terminal. Using a special spark plug wrench, we unscrew the spark plug and replace it.
• After that, we assemble the device and carry out the above procedure for starting the trimmer.

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

If the petrol trimmer still won’t start, then it makes sense to have it repaired. And the reason for this decision is simple. if you do not have the appropriate skills, equipment repair is almost impossible.

In order for the tool to serve as long as possible and not to have such problems, you should first of all read the instruction manual for the trimmer. Also, pay special attention to the engine running time at the trimmer. take a short break every 15 minutes of work and, finally, properly care for the tool, wipe it after work, lubricate with graphite grease. Observing such simple rules, you can significantly increase the service life of the tool and it is quite possible that you do not have to look for reasons why the gasoline trimmer does not start.

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 elements.
• 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 functional blocks for damage, if necessary, eliminating deformation of parts, all kinds of distortions, gusts of materials.

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 need to 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), the problem is most likely 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.

Checking the fuel mixture

Let’s say your trimmer won’t start. In this case, the first step is to check whether 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.

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 the 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.

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.

Troubleshooting strategy

Where to start troubleshooting if the trimmer won’t start? In situations where the tool stalls immediately after starting, it is worth inspecting the following units of the unit:

• fuel tank;
• spark plug;
• fuel and air filter;
• outlet channel;
• breather.

It is the breakdown of the above locations that most often leads to the fact that the trimmer does not start well. Let’s look at how to eliminate such troubles.

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.

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.

The Lawn Mower Starts Badly When Hot

The engine does not start well when it is hot

There are situations when the car does not start, after it has been running, having stood for only a couple of minutes. Drivers of completely different cars face such a problem.

In the main, this happens specifically on gasoline engines.

Regardless of what the engine is running on, a carburetor or with an electric control unit, there is such a discrepancy as the engine does not start well on hot or does not start at all on hot.

Additional checks

So, if these methods did not help, then you should check the following nodes and devices. The first step after the main check is to check the crankshaft position sensor.

It can give incorrect signals to the electronic control unit of the car, and it will no longer be able to give the correct command to injectors and other actuators, the car engine will not start. Like any other sensor, this one can get clogged or become unusable.

The first step is to clean it, and if this does not help, then you need to replace it with a new one.

The second thing to look at is the MAF sensor. It is just as important as other sensors in this vehicle system. The MAF sensor may be clogged or defective. It is best to clean the sensor so that it is visually close to the new one, this is very important in order to determine if the sensor is working.

The third thing to watch when the car won’t start is the fuel line pressure regulator. As the name implies, it regulates the pressure in the pipes through which the fuel flows in the injectors.

The fourth explanation, due to which a heated car engine may not start, is that the idle speed regulator does not work. It is needed in order to ensure the correct operation of the engine during idle.

The fifth reason is high pressure wires. It is they who conduct electric current to the candles, which ignite the fuel mixture in gasoline engines. You can visually identify a faulty high pressure wire. If your high pressure wire has cuts, torn spots, or other damage, it is best to replace that wire.

Hedge trimmer won’t start and leaking gas

If damage is found on one wire, then it is best to change all the wires at once. This must be done because most often the wires are installed at the same time, and if one of the wires becomes unusable, the rest will also soon become unusable.

The last thing to watch is the ignition system. In order to find out that the ignition system is faulty, you need to understand a little about the car’s device. If it was found that the malfunction is in this particular system, then it should be replaced immediately.

Taking proper care of your chainsaw

There are no unnecessary phrases in the operating instructions, everything that is offered is aimed at the trouble-free operation of the petrol cutter. Cleaning of all parts after each work cycle facilitates the easy removal of uncured residues and dirt. You need to clean only the cooled nodes. This technique contributes to the quality of air cooling of the engine and gearbox.

When storing the equipment for the winter, conduct an audit, lubricate the gearbox and piston system, Wrap the entire saw in oiled rags and store in a dry place.

It is impossible, it is 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 gearbox and engine increases. A worn-out piece of wire, when it comes off, flies at the speed of a bullet.

Why is it bad on hot? If the engine does not start well on Why the trimmer does not start. Effective mowing can lead to early wear of the engine piston group.

For more efficient mowing, it is suggested to use the “star” line profile.

The benzokos does not start on a cold

When starting a cold engine, it is not recommended to press the gas. Tilting the brushcutter so that the air filter is on top, press the fuel suction button 5-6 times, set the function switch lever to the “start” position, pull the starter cord several times until the engine starts. After a few seconds of running the motor, turn off the starting system.

Air filter

If your petrol brushes start poorly or immediately stalls after starting, you should pay attention to the air filter, as it can be clogged, as a result of which air does not enter the combustion chamber, and the fuel does not ignite.

To check if the filter has a case, remove it and try starting the engine. If it works, then the reason has been found. The filter needs to be replaced or rinsed well and dried before installation.

In the event that you find oil in the air filter, it must be washed with gasoline, squeezed well and dried for at least 2 hours before reinstalling.

If, however, with the air filter removed, the unit still does not start, then it is recommended to check the fuel filter.

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.

Breather

The breather is a check 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.

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

Cleaning the breather is very simple: disassemble the valve and rinse all of its components. In some petrol cutters, 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.

The petrol cutter will not start or it will start, but it stalls. What is the reason? Agrotechservice

• To understand this, you need to know the principle of operation of the unit as a whole. It also happens that, just bought, a new saw does not start, and it starts running around the service centers, in such cases it is recommended:
• carefully read the instruction manual;
  to study in detail the method of the first start-up and running-in of petrol cutters;
  try to understand how the product works;
• how gasoline is pumped up and so on.
• Reasons for malfunction of petrol cutters:
• the quality of the gasoline is poor;
  incorrect proportion of gasoline and oil;
  clogging of the fine filter;
• the spark was gone.

The main thing. fuel mixture!

In this case, the remnants of plastic dissolved in an aggressive environment do such terrible things in the combustion chamber that you will definitely not be able to do without completely overturning the mechanism. But you will certainly remember forever how to store fuel correctly.

What to do when the fuel was definitely normal, there is a spark, but the petrol trimmer will not start? It is possible that you just filled the candle with gasoline. In this case, it must be turned out, wiped with a clean cloth and dried. By the way, it will be quite useful to check the candle itself for performance.

Perform Cold Start Correctly!

Often, petrol trimmers do not start after trying to “put them into operation” after long-term storage. Launch failures in this case are often caused by incorrect user actions.

If you are faced with this particular phenomenon, then during a cold start you need to close the damper, and then pump a small amount of the fuel mixture into the carburetor. Then pull the starter handle until you feel resistance, then start the trimmer with sharp and energetic movements.

What to do when petrol trimmers won’t start?

The petrol trimmer is a surprisingly useful tool that can be used to mow not only a miniature front lawn, but a whole lawn of considerable size. Unfortunately, there is nothing eternal in this world, and therefore you may face the fact that petrol trimmers do not start.

It often happens that users of this kind of cars are trying to “save money” by pouring into the tank not fuel with a normal octane number, but something incomprehensible that has been in a plastic canister for almost a dozen years.

reasons

There are not only situations when the petrol trimmers do not start, but there are cases when, after starting, they work for a couple of seconds and immediately stall. Inspect the spark plug again: if it is “thrown over”, and this situation repeats even after wiping and drying it, go to the “revision” of the air filter.

Most likely, it is completely oiled and needs to be replaced. If everything is fine with the filter, it may be that the ignition coil is out of order.

In the case when the petrol trimmers do not start, and you have done all of the above, the muffler may be clogged. It must be dismantled, burned on a burner, after which all carbon deposits can be easily shaken out.

Even if your trimmer does not start even after such bullying, you cannot do without disassembling the carburetor. It may very well be that the dropping of the needle in it is to blame for everything. In any case, disassembling and flushing this whimsical mechanism will certainly not interfere.

In general, when the trimmer began to be capricious and stall, it is advisable to carry out full preventive measures: completely change the fuel mixture, try a different oil, and also change the spark plug without fail. Practice shows that in many cases it is cheap low-quality candles that are to blame.

Troubleshooting A Two-Cycle Engine That Won’t Start

We’ve covered the most common reasons why the trimmer won’t start. If the matter is in something more “exotic”, you cannot avoid going to the service center. You will probably find smaller and more obvious breakdowns yourself.
