Why A The Gas Trimmer Doesn't Start? Causes And Remedies

Recently, the gasoline trimmer has acquired the status of one of the main tools in the arsenal of summer residents. And it is not surprising, because the motorized spit allows you to put the garden plot in order quickly. However, sometimes it happens that the trimmer does not start on the hot and even on the cold. In such situations, you have to determine the cause of the fault independently. 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 further.

Troubleshooting strategy

How to start troubleshooting if the trimmer does not start?

In situations where the tool stalls immediately after start-up, it is worthwhile to inspect the following components of the unit:

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

It is the failure of the above locations most often leads to a bad start trimmer. Let’s look at how to eliminate such troubles.

Checking the fuel mixture.

Suppose you do not start the trimmer. In this case, the first step is to check whether there is enough fuel in the tank, as well as assess the quality of the fuel mixture. It is necessary to fill the mobile unit with an exclusively high-quality gasoline. It is recommended to use fuel whose brand is not lower than AI-95. Filling a trimmer with the fuel of unknown origin, bought not at a filling station, is fraught with frequent malfunctions of the tool. It may cause damage to the cylinder-piston system. Repair, in this case, often exceeds the cost of the device itself.
Why won’t the gas trimmer start? It can also lead to improper preparation of the fuel mixture, which consists of oil and gasoline. The manufacturers specify the proportions in which these components are connected in the trimmer manual. To prepare the fuel mixture is not recommended in large quantities, that is, for the future. After all, with long-term savings, there is a loss of the determining properties of the substance. Therefore, if the trimmer does not start, you should drain the old fuel and use a freshly prepared fuel mixture.

Candle channel diagnostics

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 mechanism may lie in the excessive moistening of the candle channel.

To diagnose and fix the problem, do the following:

  1. Unscrew the candle. Wipe it thoroughly and then dry it.
  2. Drain excess fuel in the chamber through the corresponding candle hole.
  3. Clean the old candle if there is carbon on its surface. To cope with the task will allow the use of conventional ladies nail files or needle files.
  4. When installing the element in place put a gap of 1 mm. To check the parameter, it is enough to place any coin in the lumen.
  5. Assemble the function block back.
  6. Try to get a trimmer.

It is recommended to dry the candle channel for at least half an hour. However, in no case should not resort to calcination of its elements. After all, heating the spark plug can lead to its final damage. What to do if the maintenance of the functional unit was performed following 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 saturated with fuel. It should only be slightly hydrated. To resort to such actions should be to ensure ignition. After all, no matter how strong a candle gives the spark, there is simply nothing to ignite in a dry chamber.
Even if in this case, the trimmer does not start, it is worthwhile to assess 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 apply to the services of wizards who will perform the reinstallation of the node.

Check filters.

Another common reason for which the trimmer does not start is the presence of blockage in the filter area. To confirm the guess, it is enough to dismantle the specified unit 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 the surface of the filter element, you must use a new grid. When resorting to such actions, you should not leave the suction nozzle completely without a filter. After all, haste, in this case, may lead to the need to repair the entire piston group of the engine assembly.

Breather cleaning.

Often, the engine brand trimmers stall as a result of clogging the breather. The main task of this component is to equalize the pressure in the fuel tank. If the unit is contaminated, a vacuum is formed here, which makes it difficult to supply fuel. To eliminate the malfunction, the breather can be cleaned with a regular sewing needle.

Outlet Diagnostics.

Stable functioning of the trimmer can be disrupted as a result of 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 models of trimmers of the older generation. The issue of dismantling the sparking grid and cleaning it is solved.

How to prevent the occurrence of sudden damage during the operation of the trimmer?

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

  1. Conduct timely, regular technical inspection of the main mechanical components of the device.
  2. Trim the trimmer exclusively with fresh fuel, the quality and origin of which is beyond doubt.
  3. Check after each use of the tool, whether oxides and deposits are formed on the surface of the ignition system elements.
  4. Avoid heavy trimmer loads during work.

For the unit to remain in working condition, it is necessary to prepare it for storage during the winter period properly. First of all, the instrument should be completely disassembled and then rinse and clean the components. It is also important to inspect the functional blocks for damage, if necessary, by eliminating the deformation of parts, all sorts of distortions, gusts of materials.

Recommendations for the storage of gasoline trimmer in the offseason.

Placing a trimmer for storage, it is worth filling the gearbox with a sufficient amount of oil. Then you need to clean the air filter, partially disassemble, flush and wash the engine unit. After drying all the mechanisms should be lubricated moving parts. 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 candle hole and scroll the crankshaft. If you store the gas trimmer in the off-season is planned not in the house, it is recommended to tightly wrap the engine of the unit with an oily rag. It will avoid the development of corrosion on the surface of important components of the mechanism.

Finally.

As you can see, there are several reasons why a gasoline trimmer may not start. However, with a serious approach to the task, the faults indicated in the material are quite easily eliminated with their own hands. Ask for help to specialists is only in case of critical damage. In the end, you should always correlate the cost of self-repair with the prices for servicing the unit in the workshop.
