Why Gas Trimmer Does Not Start
Recently, a gas trimmer has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized spit allows you to quickly put your personal plot in order. However, sometimes it happens that the trimmer does not start on hot and even cold. In such situations, you have to independently determine the cause of the malfunction. Let’s find out what to do if the trimmer does not start. The reasons that most often lead to such troubles will be discussed below.
How to start troubleshooting if the trimmer does not start? In situations when the tool stalls immediately after start-up, it is worth inspecting the following units of the unit:
- fuel tank;
- spark plug;
- fuel and air filter;
- exhaust channel;
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.
Fuel mixture check
Let’s say you do not start the trimmer. In this case, the first step is to check whether there is enough fuel in the tank, and also to evaluate 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 whose brand is not lower than AI-95. Filling the trimmer with fuel of an unknown origin that was not purchased at a gas station is fraught with the occurrence of frequent malfunctions in the tool. This may cause a malfunction of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.
Why doesn’t the gas trimmer start? Incorrect 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 extremely not recommended to prepare the fuel mixture in large volumes, that is, for the future. Indeed, with long-term savings, the loss of the defining properties of a substance occurs. Therefore, if the trimmer does not start, it is worth draining the old fuel and use a freshly prepared fuel mixture.
Diagnosis of the suppository canal
What to do if the used fuel mixture is in perfect order, but the gas trimmer still does not start? The reasons for the failure of the mechanism may lie in the excessive wetting of the candle channel. To diagnose and fix the problem, do the following:
- Unscrew the candle. Wipe it thoroughly and then dry.
- Drain excess fuel in the chamber through the corresponding spark plug hole.
- Clean the old candle if there is soot on its surface. To cope with the task will allow the use of ordinary ladies’ nail files or needle files.
- When installing the element in place, set a gap of 1 mm. To check the parameter, just put any coin in the lumen.
- Reassemble the function block.
- Try to have a trimmer.
Drying the candle channel is recommended 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, is there 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 moistened. To resort to such actions should be to ensure ignition. After all, no matter how strong a spark is given by a candle, there will simply not be anything to ignite in a completely dry chamber.

If even in this case the trimmer does not start, it is worth evaluating the quality of the contact between the high-voltage wire and the candle. In the absence of a spark (in the presence of 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 masters who will reinstall the site.
Another common reason that does not start the trimmer is the clogging 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, you will most likely have to replace the air filter or at least thoroughly purge the old one. In the presence of heavy pollution on a surface of the filtering element it is necessary to use a new grid. When resorting to such actions, one should not leave the suction pipe completely without a filter. Indeed, the rush in this case may lead to the need to repair the entire piston group of the engine unit.
Cleaning the breather
Often, the engine of branded trimmer models stalls as a result of clogging of the breather. The main task of this component is to equalize the pressure in the fuel tank. In case of contamination of the unit, a vacuum forms here, which significantly complicates the supply of fuel. The problem can be rectified by cleaning the breather with a regular sewing needle.
Stable operation of the trimmer may be impaired due to the accumulation of dirt in the exhaust channel or the formation of blockage on the silencer mesh. This problem most often occurs during the operation of older generation trimmer models. The issue is solved by dismantling the anti-spark mesh and cleaning it.
How to prevent sudden breakdowns during operation of the trimmer?
To ensure that the unit is always in a functional state, it is worth observing several simple rules:
- Conduct timely, regular technical inspection of the main mechanical components of the device.
- Refuel the trimmer exclusively with fresh fuel, the quality and origin of which is beyond doubt.
- Check after each use of the tool whether oxides and deposits have formed on the surface of the ignition system elements.
- Avoid heavy load trimmer during work.
In order for the unit to remain in working condition, it is necessary to properly prepare it for storage in the winter. First of all, you should completely disassemble the tool, and then flush and clean the component 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.
Off-season gasoline trimmer storage recommendations
When placing the trimmer in storage, it is worth filling the gearbox with enough oil. Then you need to clean the air filter, partially disassemble, blow and rinse the engine of the unit. Having dried all the mechanisms, lubricate the movable elements. 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, after which pour a small amount of oil into the spark plug hole and scroll the crankshaft. If it is planned to store the gas trimmer in the offseason not in the house, it is recommended to tightly wrap the engine of the unit with oiled rags. This will avoid the development of corrosion on the surface of important components of the mechanism.
As you can see, there are a number of reasons why a gas trimmer may not start. However, with a serious approach to the problem, the malfunctions indicated in the material are quite easily eliminated by one’s own hands. Seek help from specialists only in case of critical breakdowns. In the end, you should always correlate the cost of self-repair with the prices for servicing the unit in the workshop.
