Gasoline trimmer calm will not start

The petrol lawn mower will not start. Why?

Will not start after winter

In this case, you just need to drain the old and possibly even frozen fuel and fill in the freshly prepared mixture. Then you need to perform the same manipulations as during the first start of the lawn mower.

The lawn mower will not start

If at the first start, your new lawn mower refuses to start, try the following: based on the air temperature outside, set the appropriate position of the air damper (at temperatures less than 30 C. “damper closed”, over 30 C. half-closed position), then pump into the carburetor fuel and gently, but rather sharply, pull the starter handle until you feel some resistance. Repeat these steps in the same sequence several times. A brand new instrument must start. If this finally happened, you can safely get down to work, having previously fully opened the damper.

If the lawn mower is no longer new, then it is necessary to start its inspection from the gas tank. If the device has not been in operation for a long time, then it is necessary to drain the old gasoline, which has the feature of “running out”, i.e. lose their octane properties, and refill with fresh fuel mixture. The gasoline / fuel ratio, as well as the required grades, are usually indicated in the operating instructions for the tool.

Now you need to check the spark plug. either the problem is in it itself, or in the fuel system. The candle must be carefully unscrewed and its condition assessed. If the candle is heavily flooded or there is black carbon on it, then it must be removed, cleaned and dried. Drain the excess fuel, if any, from the spark plug holes, drain the cylinder itself, then screw in the dried or, even more desirable, a completely new plug. If the plug was completely dry initially, you need to look for a problem in the fuel supply system. First, check the fuel filter. To do this, disconnect the suction hose and remove the dirty filter from it, clean it and reinstall it, or replace it with a new one. If this does not help, you should contact the service center specialists.

Starts up and stalls

If the mower stalls after starting, check the air filter. When this filter is heavily clogged with dust, it stops passing the required amount of air into the carburetor and allows dust to enter the fuel mixture. It is necessary to carefully remove the contaminated filter, clean and rinse in gasoline. If the air filter is clean, and the tool still stalls, then it is better to contact a professional to determine the cause of the malfunction and eliminate it.

Trimmers are reliable and durable (provided they are properly maintained, of course). Most often, malfunctions occur due to contamination of structural elements.

If the engine of your petrol cutter does not start, does not pick up speed, does not reach the power you need, or suddenly stalls, the reason may be:

  • low-quality fuel (fuel mixture), the case may be in long-term storage or in non-compliance with the recipe for preparing the mixture;
  • grass is wrapped around the shaft of the fishing line / knife;
  • clogged air filter / muffler;
  • unbalanced carburetor.

The gasoline trimmer is not gaining momentum: the reasons and features of the repair

To cut grass on a small lawn, it is not necessary to purchase an expensive and bulky lawn mower; it can be easily replaced by a gasoline / electric trimmer. The device of these machines is quite simple, they are easy to use and unpretentious in maintenance. But sometimes problems do occur. One of them. when the trimmer does not develop the maximum number of revolutions. will be discussed in this article.

Troubleshooting methods

The first three reasons are fairly easy to eliminate. If the matter is in the mixture, you need to pour out the old fuel from the tank, prepare a new emulsion from high-quality gasoline and engine oil (if your engine requires a mixture) and pour it into the fuel tank. If the trimmer is running on clean gasoline, it’s even easier.

In the second case, it is necessary to carefully free the trimmer parts from the wound grass.

If the filter is clogged, you can try rinsing it. If this procedure does not work, replace it with a new one.

The last reason why the brushcutter does not work properly will require a little more knowledge and skills from you.

How To Start A Weed Wacker If It Won’t Start – Cleaning The Carburetor

In order to properly adjust the carburetor of the brushcutters, a certain procedure must be followed. First, clean the air filter thoroughly. The easiest way is to rinse it (it is advisable to spray the filter with water regularly after 9-10 hours of operation).

After that, in the diagram of your trimmer, which is in the instruction manual of the device, find the adjustment screws. There are usually three of them: the first is responsible for fuel supply, the second is for idling, and the third is designed to limit the number of maximum engine speed.

Next, turn on the unit and wait for the engine to warm up.

Tighten the first (fuel mixture) adjusting screw slowly. Catch the moment when the motor starts to stall and turn the propeller back 45 degrees. If you did not have time and the motor stalled, the screw should be turned 90 degrees. Open the throttle and watch the revs increase. Next, slowly unscrew the screw (each turn is the same 45 degrees) until the moment when, at full throttle, the engine begins to firmly give out maximum revolutions.

The second screw, as mentioned above, controls the engine idle speed. By loosening it, you decrease the number of revolutions, while twisting it, you increase it. The screw needs to be adjusted so that the motor runs reliably at low revs. For better starting, speed up the engine slightly. At the same time, make sure that the motor rotates several tens of times before starting the movement of the knives / line reel. If the engine starts poorly, tighten the screw a little.

After you have adjusted the first two screws, test the operation of the unit at maximum engine speed. If necessary, you can limit it (maximum). this will protect the motor from “boiling”. To do this, you need to tackle the third screw. Unscrew the locking nut until the adjusting screw can be safely turned. To increase the maximum number of revolutions, the screw must be loosened, to decrease. on the contrary, tighten. Fix the position of the screw with a nut. Test the motor again.

Regularly check the position of the screws. the high level of vibration inherent in brushcutters can cause them to involuntarily shift.

Remember that carburetor adjustment is not a final procedure. During the operation of the brushcutter, you will most likely have to tinker with it more than once, because an unbalanced carburetor means both increased fuel consumption and quick failure of the spark plugs, not to mention a decrease in the power and performance of the device.

Little tricks

  • If you are unable to tighten / loosen the adjusting screws properly, it may be that the spring is too thick and stiff. Then you can choose instead of her a more suitable.
  • If your unit does not need pure gasoline, but its mixture with engine oil, strictly observe the proportions specified in the operating instructions. There is one trifle: the recommended ratio is 1: 25 (for all brands of oil) or 1: 50 (for “native” oils). Try the first ratio first. If, with this recipe, oil drips appear on the motor, and a strong carbon deposit forms on the candle, reduce the proportion of oil by half. This usually helps to fade traces and reduce the amount of carbon deposits.
  • To clean the spark plug electrodes from combustion products, you can use fine-grained “sandpaper”. Wipe them down with a dry cloth first and then gently sand them with sandpaper. If the space between the body of the device and the insulator is also clogged, a regular, unbent paper clip can help clean it. To do this, briefly soak the candle in diesel fuel, and then scrape off the dirt. If the blockage is small, one procedure is sufficient. In case of heavy dirt, it is sometimes necessary to repeat it several times. After complete cleaning, the candle must be wiped dry from the remaining diesel fuel, and then it can be used as directed.
  • Please note that a brushcutter (gasoline, electric or battery) of foreign production requires a little more maintenance than domestic ones. In particular, many strongly recommend entrusting the adjustment of the carburetor of a two-stroke engine to professionals, especially if your purchase has not expired the warranty period.
  • And finally, one more tip: follow all the manufacturer’s recommendations for the operation and maintenance of the device. This will prolong its smooth operation.

Benzokosa Calm Fs 38 Will Not Start

If you are often faced with the need to mow grass in this area, then modern devices are used specifically for this purpose in the manner of trimmers or lawn mowers. Among other solutions on the modern market, petrol cutters are presented, with the help of which, of course, maintain the surrounding area in a tidy condition.

For one book, one of the fundamental advantages of a petrol brush is that it is not tied to a power source, observing the principle of electronic units. However, such equipment can be used even on uneven areas and in inaccessible places, this should include areas under bushes.

The Stihl FS 55 petrol cutter device is understandable for you if you intend to operate the equipment, let alone repair it. The gasoline engine in this unit is almost the same as in the chainsaw. But the tire is the latter fixed to the motor reducer by a long tubular rod. Inside there is a shaft that transmits torque from the motor to the working tool. This design is suspended from a strap that is slung over the shoulder. This allows you to hold the tool on the weight, which is fundamentally with the sensitive weight of the chainsaw.

A handle is fixed to the bar of the unit, with the help of it, of course, move the end of the bar with the working equipment. Gas cutter “Calm FS 55”, the annotation for repairs which is presented according to the text of the article, has a protective shield in the form of a casing, which excludes injuries during operation. The tool itself is a round drum with thick line coming out of the holes on both sides. When the drum spins, the line pulls under the action of centrifugal force and hits the grass, chopping it.

Gas cutter “Calm FS 55”, the technical properties of the busy will be presented for you below, has a quick-wear nylon line. It is renewed from time to time by unwinding the reel inside the drum.

Rules for the operation and storage of petrol cutters

In order for the brushcutter to start well in the future, it is necessary to provide it with good storage and operation conditions:

  • during operation, carefully monitor the cooling system, carefully and in time clean the channels in the housing, as well as the ribs of the starter;
  • if necessary, use solvents, kerosene and other detergents for cleaning;
  • do not clean the tool “hot”. let it cool;
  • strictly follow the instructions for the operating mode, otherwise you may overheat the engine;
  • if you do not plan to use the petrol cutter in the next month, the fuel mixture must be drained from it, since over time it decomposes into heavy fractions, which will definitely clog the carburetor channels;
  • after draining the fuel, let the trimmer idle until it stalls, this will help completely remove the remaining working mixture.

Follow these steps before winter storage:

  • disassemble the braid completely, rinse and clean all the details you can;
  • inspect the parts for damage, if necessary, eliminate distortions, tears, bends and any other malfunctions;
  • fill in a sufficient amount of oil into the gearbox and clean the air filter;
  • you can partially disassemble the motor, rinse, blow out and grease all moving parts;
  • in order to lubricate the piston, you need to unscrew the spark plug, lift the piston to the dead center with the starter, pour a little oil into the spark plug hole and turn the crankshaft a couple of times;
  • if you store the brushcutter outside the house, wrap the engine with an oily rag.

Remember, careful observance of the rules will allow you to forget that it is bad to start a petrol cutter for several seasons.

We carry out diagnostics of the candle and candle channel

If the quality of the fuel mixture is not in doubt, and the brushcutter stalls at start-up, then a flooded candle may be the cause. Here, for repairs, an ordinary candle wrench is suitable (every motorist probably has) and a spare candle.

  • We unscrew the candle and wipe it;
  • Dry it thoroughly (do not ignite);
  • We drain the excess fuel in the chamber through the spark plug hole and dry it;
  • We clean the old candle from carbon deposits using a file or a lady’s file;
  • We set a gap with a distance of 1 mm (you can check with any coin);
  • We put everything back in place and try to start the trimmer.

It is necessary to dry the canal for at least 30–40 minutes. Otherwise, there is a risk of re-filling and a new candle.

If the candle is working, the socket where it is located is completely dry, and the petrol cutter does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful spark the candle gives out, there is simply nothing to light up in a dry chamber.

If the trimmer motor still does not start, a reason such as the absence of a spark due to poor contact between the spark plugs and the high-voltage wire should be ruled out. If the connection is of good quality, and there is still no spark, most likely, your ignition unit has “flown”. Here it will not be possible to do without a master, since the part is not repaired, but is sold as a single unit.

Stihl FS 130 brushcutter won’t start Defect diagnostics, disassembly, repair

The unit is serviced by only one person, with all this, there should be no outsiders in an area with a radius of up to 15 m. Otherwise, you will always be injured by thrown objects. Starting the engine of the “Calm FS 55” petrol cutter, the properties are busy presented in the text of the article, should not be carried out manually. When the throttle is released, the cutting tool will move automatically for a period of time. Flammable materials should be kept away from the hot gas stream and the surface of the hot muffler, as this could be a prerequisite for a fire.

The petrol cutter works at the expense of gasoline, which simply ignites. Therefore, at the time of refueling, it is harmful to smoke nearby. The engine turns off before refueling. It is not recommended to carry out such manipulations until the engine has cooled down, because the fuel can overflow and begin to pose a fire hazard.

The fuel tank lock is opened with special care, because excess pressure will be a prerequisite for fuel splashing. Gas cutter “Calm FS 55”, the operating summary is busy, you can examine it before using the device, refuel in well-ventilated places. If fuel is spilled, the device should be cleaned of it immediately so that it does not get on the clothes, otherwise the latter should be changed immediately.

After refueling, tighten the screw lock of the fuel tank to the full. This will reduce the possibility of unscrewing it due to motor vibration. If this is not foreseen, there is a danger of fuel leakage. Check for leaks as a matter of principle. If fuel is spilled, then the engine should not be started, otherwise there is a risk of burns.

Gas cutter “Calm FS 55”, which is required to be supplied in the kit and is desirable to be investigated by you before work, is a high-tech equipment that is not difficult to maintain. You will be able to make repairs and adjustments without the help of others. As for the carburetor, this is a matter of 5 minutes.

The main discrepancies in the carburetor malfunction will be breakdowns and blockages. To be able to find out the reason, unscrew the fuel filter cap and pull out the mesh filter. If he has accumulated dirt, then blowing or flushing in gasoline will help. If you find visible configurations on the filter, then it should be replaced with a new one.

The fuel supply pipes are also damaged. The failure of the carburetor starting device sometimes happens due to clearances. Gasoline or acetone is used for flushing. You will like the carburetor better with compressed air; for this purpose, you use a comfortable repair practice. The outlet or inlet pipeline is depressurized, as well as the throttle body and other places where the carburetor parts are connected to each other. If you are faced with the aforementioned problem, then you can make sure here by means of a soap solution, which is applied to a suitable area.

The equipment described above must be used with special clothing and equipment. Dress by a man should not interfere during work. Choose one that fits perfectly to the body. It is necessary to exclude wide sleeves that can catch on bushes, tree species, as it is also called the moving parts of the unit.

Basically remove ties and scarves. This also applies to jewelry. While starting the “Calm FS 55” petrol cutter, you need to wear protective boots with a rough sole. It is essential to use a special protective helmet and goggles, which will exclude damage to the organs of vision.

The engine is started far from the native land 3 m and not just from the place where the device is refueled with fuel. These works cannot be performed indoors. Until you need to take a stable, secure position. The motorbike is held very tightly at the same time. The cutting tool should not come into contact with the ground or objects, because when starting it can spin.

Construction site

Petrol trimmers are perfect for backyard weed control and hay making. Yes, as the grandfather’s “Lithuanian” they also proved to be irreplaceable assistants. But there is only one problem: even the old braids had to be repaired after the season.

What to do if the petrol trimmer breaks down? Repair in a service center is not a cheap pleasure. Is there a chance to somehow rectify the situation on your own?

Fuel mixture and refueling

For the convenience of preparing the fuel mixture, it is better to have a special canister. where one part contains gasoline and the other 2-stroke oil. We recommend getting one like this, it is very convenient to use

Next, take a measuring container with a scale applied to it, with its help you can prepare the mixture as accurately and quickly as possible. Look in the instructions what brand of gasoline and 2-stroke oil are recommended by the manufacturer of your petrol cutter model. Pour gasoline and oil into a container for preparing a fuel mixture, according to the proportions indicated in the instructions. Then carefully pour the prepared mixture through a funnel into the trimmer fuel tank. The ratio of gasoline and oil should be exactly as indicated in the instructions. This is a very important point.!

How to start a petrol trimmer

The process of commissioning petrol brushes, whether you bought it now or got it after winter storage, the rules listed below will allow you to avoid basic mistakes that can damage the tool.

Let’s say you just bought a petrol trimmer. Take the instructions out of the box and see if you have all the parts of the brushcutter that are listed. After that you can start building.

Starting petrol cutters with cold engine

To start the brushcutter for the first time, locate the choke lever and place it in the closed position. Turn on the ignition on the handle. If your model has a manual fuel pump, popularly called suction, then press it 3-5 times until you see the fuel mixture inside the primer. The tool is now ready to run. Lay the trimmer on a flat surface to ensure a stable position. Smoothly pull the starter rope until you feel its resistance, and then pull the rope towards you with a sharp movement 3-5 times.

If the engine starts after 5 jerks, open the choke. If this does not happen, open the air damper anyway (if the damper is open and you continue trying to start the engine, the fuel will flood the spark plug and have to dry it, and this is a waste of time).

If the engine does not start when the throttle is open, then close it and continue pulling the cord. The first launch can be quite difficult and require up to 15 jerks. After the engine has started to work, press the throttle lever once, so you engage idle speed. Now let the engine run and warm up. After that, it can be stopped by clicking on the “Stop” button.

Starting a warm engine

It’s very simple. Move the switch to the working position and pull the cord before starting. If you do everything according to the instructions, then there should be no problems with starting a serviceable petrol cutter.

Basic startup errors

Let’s list the main mistakes that beginners make when starting a gasoline trimmer:

  • starting the engine with the ignition off;
  • starting with a closed damper with the number of jerks more than 5 times;
  • improperly formulated fuel mixture.

Gasoline trimmer calm will not start

Petrol trimmer won’t start. What to do?

Sometimes the trimmer or brushcutter stops starting at the most inopportune moment, disrupting the planned work at the summer cottage or suburban area. Before contacting a service workshop, you can sometimes try to eliminate the cause of the malfunction yourself.
Let’s take a Husqvarna 128 R trimmer as an example. So, you did everything according to the instructions. with a primer (see Figure 1) pumped fuel into the carburetor, the throttle lever was moved to the “closed” position, you try to start, but the engine does not even “grab”. Moving the throttle (air) valve lever (see Figure 2) to the “Open” position does not give any result. Trimmer will not start.

Figure 1- Primer (booster pump)

Figure 2-The device of the petrol brush: throttle (air) valve, manual starter

One of the most common reasons is excessive priming of fuel, leading to a “flood” of the spark plug. In this case, try to do the following: move the throttle lever to the “open” position, press and hold the throttle trigger while trying to start the trimmer. If after 5-6 attempts to start the trimmer failed, turn out and dry the candle. Check for spark plug between electrodes. To do this, put the spark plug cap on the spark plug, attach the spark plug body to the metal surface of the cylinder and crank the engine with a starter. If there is no spark between the electrodes. replace the spark plug. Before screwing in the spark plug, turn the trimmer with the spark plug hole down and crank the engine 2-3 times with the starter to remove the remaining fuel from the cylinder. Wrap the candle and repeat the steps described at the beginning of the paragraph.
If, after the performed manipulations, the trimmer does not start, then most likely the cause of the malfunction is more serious and you need to contact the specialists of the service workshop. Read more here.

Petrol trimmer does not start well

So what if the petrol trimmer won’t start well or won’t start at all? The most common reason for such a breakdown is poor quality fuel. Remember that, for example, trimmers of the Shtil and Husqvarna brands are unlikely to start on fuel of a quality lower than AI-92. You should not save on fuel, because repair of parts of the cylinder-piston group can be one third of the total cost of the scythe, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.

What to do if high-quality fuel is poured into the gas tank, there is a spark, but the tool still refuses to start? It is necessary to check the condition of the candle. It is located in the center of the mower body. It must be carefully unscrewed and make sure there is no plaque on it. If there is, then carefully clean the candle from carbon deposits and dry it.

If the brushcutter does not start even after the methods suggested above, then you need to try to remove the air filter and start the device without it. If the trimmer still does not work, thoroughly dust the old filter or buy a new one.

It also happens that the mower works for a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try opening the filler cap of the gasoline filler cap. a suction sound should appear. Then screw the cap back on. If you do this manipulation while the trimmer has just started to stall, then the speed will be restored, and you can continue to work. If the mower stalls before opening the lid, then you just need to start it as expected according to the instructions.

Trimmer won’t start after winter

How to be in such a situation? Don’t worry and panic. This is a very common problem that can be solved in just 3-4 minutes. Firstly, if last year’s fuel remains in the gas tank, then it must be drained. Gasoline loses its octave properties after 2 weeks of inactivity. Secondly, you need to start a petrol cutter after a long stagnation in a slightly different way. First you need to open the throttle and pump a little fuel mixture into the carburetor, then pull the handle until you feel a little resistance. After that, you can start the trimmer.

Trimmer won’t start. Why?

A petrol trimmer is a surprisingly useful thing that can be used to tidy up not only a miniature lawn in the backyard of the house, but also mow a lawn of considerable size without any extra hassle. But, like all things in this world, it tends to break. In this article we will try to figure out what to do in cases where the trimmer refuses to work.

Trimmer starts and stalls

If, when you try to start the trimmer, it starts, but immediately stalls, then the air filter may again be the reason for this. It is necessary to remove it and check if it is clogged with dust. If this is true, then you need to thoroughly clean it or purchase a new one. Also, the problem may lie in the malfunction of the ignition coil. In this case, it is better to take the mower to a service center.

Model characteristics on video.

gasoline, trimmer, calm, start

However, whichever model you choose, you need to follow certain operating rules recommended by the manufacturer in order to avoid possible breakdowns.

It should also be remembered that a piece of cable, spun by centrifugal force when the trimmer head rotates, flies like a bullet. Imagine what would happen if it hits the leg or someone’s eye?

Using a cable, wire, or multicore cable instead of a fishing line leads to a quick breakdown of the trimmer. In addition, it is a direct violation of safety regulations.!

Experienced users recommend buying a line with a “star” profile. Compared to a round one, it mows much better, stalks as thick as a finger, a fishing line with a diameter of 3 mm chops into an easy one, and is less consumed.

In no case should you store gasoline in a plastic container from under water. When mixing the fuel mixture, a static charge accumulates, you can “catch” a spark.

Therefore, at gas stations it is not allowed to fill gasoline in plastic cans, only in metal ones. Before pouring gasoline into a metal canister, it is better to put it on the ground, so static is removed from the body.

But there are situations when simple manipulations with the brushcutter do not help. The engine still won’t start. In this case, we are going to check the power supply and ignition system, guided by the rule “the engine does not work if there is nothing to burn or nothing to ignite”.

Benzotrimmer loves cleanliness. It is necessary to monitor the cleanliness of the air filter and fuel. Gasoline bought at a gas station is better to stand for 2 days and pass through the simplest filter. a piece of bike cloth.

We check the electrical equipment as follows:

We unscrew the candle, inspect the gap between the electrodes. We can set the correct gap between the electrodes in the “old-fashioned” way. We take the razor blade, break it in half and insert a homemade probe between the electrodes. If the blades fit tightly, then the gap is perfect.

We put the cap of the high-voltage wire on the candle and lean the candle against the metal surface of the engine. We pull the starter several times. If the spark hits one point well, then the gap is adjusted correctly. If not, the spark is weak or “wandering”, then it is necessary to re-adjust the gap between the electrodes.

During the engine running-in period (this is approximately the work of the trimmer on 2-3 tanks), the amount of oil can be increased. For example, mix it with gasoline in a 30: 1 ratio.

A small amount of oil mixed with gasoline leads to increased wear of the cylinder-piston group. An excess of oil in the mixture, although not so fatal, is also harmful. Coking of the piston rings, rapid formation of carbon deposits in the combustion chamber, and a drop in engine power may occur. In addition, the muffler mesh screen is coked. Therefore, some users (after the end of the warranty period for the trimmer) recommend dismantling it.

The gasoline used in the brushcutter is AI 92. The brand of gasoline is precisely specified in the operating instructions. You should not try to “force” the engine by pouring 95th gasoline into it. This can cause overheating, erratic trimmer operation and breakage.

It is not recommended to leave fuel in the trimmer tank during extended shutdowns. It is better to end the working day with the entire mixture completely exhausted. If this is not done, then, since the gasoline will evaporate from the engine overnight, and a thin film of oil will remain, the carburetor jets may become clogged. This will cause difficulty the next time you start the engine.

It is also necessary to observe safety precautions when storing fuel. Many people pour gasoline into a plastic water bottle. Is it worth doing this?

You bought yourself a new petrol trimmer and immediately got into trouble with it. It starts very badly. If you mow a little, and then turn it off, then turning it on “hot” is an even bigger problem than “cold”. What to do with it, I don’t know how to get it right?

The instruction for the brushcutter plant sounds like this:

Switch on ignition.

Pump up fuel with a silicone button (primer) located on the bottom of the carburetor. Pressing must be done as much (or a little more) as written in the instructions, usually about 8-10.

Close air damper.

Lock the throttle lever with a stop button at high rpm.

Pull the starter handle 2-3 times. The engine should “grab”.

If the engine “grabs” and stalled, then you need to move the choke to the 1/2 position and try to start again. If the engine starts, then we release the gas and move the air damper to the “open” position. Getting started.

When performing fuel pumping manipulations, one should not be afraid to pour it over. If this happened, and, as they say, “filled the candle”, then you do not need to unscrew it, it is enough to move the air damper to the “open” position and, while holding full throttle, simultaneously turn the engine with the starter 2-4 times. After that, you can start the engine and get to work.

The continuous operation of the brushcutter is indicated in the trimmer instructions. On average, we mow for 15-20 minutes, after which we turn off the trimmer and let it cool for 3-5 minutes. Weather conditions also affect the duration of continuous operation. In hot weather, when mowing tall grass, thickets of weeds, under heavy load, the trimmer overheats faster.

Many brushcutter problems arise from improperly prepared fuel mixture. In two-stroke engines, lubrication is carried out with a special oil (not ordinary engine oil!), Mixed with gasoline. If the oil is not mixed with gasoline, the brushcutter will quickly fail. Mix the oil / gasoline in the proportion indicated in the trimmer instructions. Usually it is 1:40 or 1:50.

The question often arises: the proportion of 1:50 is how much oil and gasoline?

When your petrol lawnmower won’t start. first of all, it is necessary to check the presence of fuel in the tank. If it is missing. top up to the desired level. Often, when the device is not used for a long time, gasoline “runs out”, so it must be completely drained and refilled with new. This procedure must be done carefully so that fuel does not get on the engine, as this can lead to ignition in the future (when the engine heats up). Which gasoline is better to use, you can find out from the technical passport of the device.

In order for the unit to start, you need to pump fuel with a primer (if available in this model) into the carburetor and set the maximum speed. You need to start the technique carefully. The starter cord must be smoothly pulled out until it stops, then pull it towards you with one even sharp movement.

A problem can occur if the air damper is not correctly positioned during the first start. Depending on the air temperature, it is completely closed or set to the middle position (above 30 C). Then it must be fully opened.

Check the air filter for dirt. To do this, turn off the machine and disconnect the wire from the spark plug. Unscrew the cover and remove the filter. Rinse it with gasoline and dry it thoroughly, or simply replace it with a new one. Remember that it is recommended to change the air filter after every 25 hours of operation.

Another reason your petrol lawnmower won’t start could be a faulty spark plug. Perhaps she was just flooded with fuel. In this case, unscrew it, clean it and check for a spark. It may not be present when the spark plug is filled with fuel. Place choke control handle (if equipped) in the CLOSED position and start the engine. If this does not help, it is better to seek help from a specialist.
