Why the petrol trimmer does not start? Reasons 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 braid allows you to quickly bring the household plot in order. 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 problem yourself. 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 do I start troubleshooting if I do not start a trimmer? In situations where the tool stalls immediately after starting, it is worth to inspect the following units of the unit:

• A tank for fuel;
• spark plug;
• Fuel and air filter;
• Outlet channel;
• breather.

It is the failure of the above locations most often leads to the fact that the trimmer is not starting properly. Let's look at how to eliminate such troubles.

Checking the fuel mixture

Let's say you do not have a trimmer. In this case, the first thing to check is whether there is enough fuel in the tank, and also to assess the quality of the fuel mixture. It is necessary to fill the motorized unit exclusively with high-quality gasoline. Use fuel that is not less than AI-95 grade. Filling a trimmer with fuel of unknown origin, purchased not at a gas station, is fraught with frequent malfunctions in the tool. This can cause damage to the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.

Why the petrol trimmer does not start? To lead to this can also be improper preparation of the fuel mixture, which consists of oil and gasoline. The proportions in which these components are connected are indicated by the manufacturers in the trimmer manual. Preparing a fuel mixture is highly discouraged in large volumes, that is, for the future. After all, with a long-term saving, there is a loss of the determining 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.

Diagnosis of the canal

What to do if the fuel mixture used is in order, but the petrol trimmer still does not start? The reasons for the failure of the mechanism can be hidden in the excessive moistening of the candle canal. To diagnose and fix the problem, you need to do the following:

1. Unscrew the candle. Carefully wipe it, and then dry it.
2. Drain the excess fuel in the chamber through the corresponding spark plug.
3. Clean the old candle if there is a deposit on its surface. To cope with the task will allow the use of a normal female nail file or nadfile.
4. When installing the element in place, set the clearance to 1 mm. To check the parameter it is enough to place any coin in the gleam.
5. Assemble the function block back.
6. Try to start a trimmer.

It is recommended to dry the candle duct for at least half an hour. However, in no case should you resort to calcining its elements. After heating the spark plug can lead to its final damage. What to do if the maintenance of the function block was carried out in accordance with the above recommendations, but the trimmer does not start, is there a spark? In this case, it is necessary to treat the screwed connection with gasoline. The latter need not be saturated with fuel. It should only be slightly moistened. Such actions should be taken to ensure the ignition. After all, no matter how strong a spark does not give a candle, in an absolutely dry chamber there will simply be nothing to ignite.

If even then the trimmer does not start, it is worthwhile to assess the quality of the contact between the high-voltage wire and the plug. In the absence of a spark (if there is a reliable connection between the specified elements), the problem is most likely caused by the failure of the ignition unit. In this situation, you will have to turn to the services of the wizards that will perform the reinstallation of the node.

Checking the filters

Another common cause, because of which the trimmer does not start, is the presence of clog in the filter area. To confirm the conjecture, it is enough to dismantle the indicated block and try to start the unit without it. If the trimmer's engine has started, it's likely that you will have to replace the air filter or at least perform a thorough blowdown of the old one. In the presence of excessive contaminants on the surface of the filter element, a new grid must be used. By resorting to such actions, do not leave the suction nozzle completely without a filter. After all, haste in this case can lead to the need to repair the entire piston engine group of the unit.

Breath cleaning

Often the engine of brand 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 the case of contamination of the unit, a vacuum is formed here, which greatly complicates the supply of fuel. The cleaning of the breather can be rectified by a conventional sewing needle.

Diagnosis of the discharge channel

The stable operation of the trimmer can be disturbed by the build up of dirt in the discharge channel or the formation of a clog on the muffler net. This problem most often arises during the operation of models of the older generation of trimmers. The issue is solved by dismantling the antisuke grid and cleaning it.

How to prevent sudden breakdowns during the operation of the trimmer?

To ensure that the unit is always in a functional state, it is worth following a few simple rules:

1. Carry out a timely, regular technical inspection of the main mechanical components of the device.
2. To fill the trimmer with fresh fuel, the quality and origin of which is beyond doubt.
3. Check after each use of the tool, whether oxides and carbon deposits were formed on the surface of the elements of the ignition system.
4. Avoid strong load trimmer during work.

In order for the unit to remain operational, it is necessary to properly prepare it for storage in the winter. First of all, it is necessary to completely disassemble the instrument, and then perform the washing and cleaning of 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.

Recommendations for the storage of gasoline trimmer in the off-season

When putting the trimmer on storage, it is worthwhile to fill the reducer with enough oil. Then you need to perform the cleaning of the air filter, partially disassemble, purge and rinse the engine of the unit. After drying all the mechanisms, you should lubricate the moving parts. To perform the processing of the piston system with oils, it is necessary to first remove the spark plug. Then you need to move the piston to the extreme position, then pour in the candle hole a small amount of oil and make a cranking of the crankshaft. If you store the gasoline trimmer in the off-season is not planned 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 parts of the mechanism.

Finally

As you can see, there are a number of reasons why a petrol trimmer may not start. However, with a serious approach to the problem, the malfunctions mentioned in the material are quite simply eliminated by themselves. Seeking help from specialists is only in case of critical breakdowns. In the end, you should always compare the cost of self-repair with the prices for servicing the unit in the workshop.
