Proper first start-up and running-in of the lawn mower are very important steps when starting to use a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, as specified by the manufacturer, since at this stage the grinding in of moving components and parts occurs. On the other hand, the first necessary skills of working with a trimmer are acquired, if we are talking about the first tool in life.

Preparing for the first start of the lawn mower

Before starting the lawn mower for the first time, it is necessary to perform a number of sequential actions:

• Inspect the gearbox and lubricate it;
• Prepare the correct fuel mixture.

Inspection of the lawn mower gearbox and its lubrication

Checking the gearbox before starting petrol trimmer must be done on a regular basis. Lack of lubrication or little lubrication increases friction gear transmission gearbox operating at fairly high speeds. As a result, overheating of the gears occurs. The brush cutter gearbox fails. Regular inspection helps prevent such damage from occurring during operation.

If, before starting the gasoline scythe, an insufficient amount of lubricant in the gearbox or its absence is detected, “LITOL” is placed in the housing. To do this, you need to unscrew the screw on the bend of the gear housing and spray in 1-2 ml of LITOL.

When working with a gasoline trimmer for a long time, add lubricant to the boom gearbox every 8-10 hours.

Preparing the correct fuel mixture

Before you start running in a new lawnmower engine, you also need to properly prepare the fuel mixture. As is known for two-stroke engines, it is prepared from special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the instructions included with the instrument or on the label lubricant. From the instructions you will also learn the recommended type of fuel, as well as the recommended type of engine oil.

Prepare fuel in small quantities, enough for one mowing of grass. Use special plastic canisters or separate glass or metal containers for fuel. It is best to draw up the oil with a medical syringe. .

Getting ready to run in new lawn mower, many people face problems in preparing the fuel mixture. And the reason for this is the discrepancy between the tool manufacturer’s instructions and the manufacturer’s instructions motor oils. The first ones recommend a proportion of 1:25. The second recommend 1:50. Who to believe? How to proceed?

According to experts, if manufacturers write a ratio of 1:25 or 1:30 in the instructions for a brush cutter, then most likely it is either a cheap tool with poor cooling, or the manufacturer does not know what kind of oil, the consumer will add. But here you need to understand that excess lubricant does not in the best possible way affects the performance of the trimmer. Excess oil does not burn out completely when the engine is running. It cokes and clogs the cylinder and piston.

What to do in this situation when running in a new tool? Ideal option will purchase exactly the oil that the lawn mower manufacturer recommends. In the case of run-in engines, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two-stroke oil for the same-name gas-powered tool. It's not cheap, but it lasts a long time. It must be mixed as written in the instructions on the can.

Remember, it is best to use the proportion provided by the oil manufacturer. But whether the proportion written on the braid is appropriate is better to find out through experiment. If, with the proportion recommended by the trimmer manufacturer, the engine is snotty with oil and smudges are visible on it, then the proportion needs to be increased.

First start of the trimmer

When everything is checked and the prepared fuel mixture is poured into the tank, the moment comes for the first start of the trimmer before running it in. To do this, you need to perform the following manipulations:

1. Place the brush cutter on a flat horizontal surface;
2. Move the choke control lever to the closed position;
3. We pump fuel into the carburetor with several pumps of primer;
4. Turn on the ignition switch;
5. Smoothly pull out the starter cord until you feel resistance;
6. Then make 3...4 sharp jerks with the cord until the lawn mower starts;
7. After starting, open the air damper.

If the lawn mower does not start or stalls the first time, slightly open the air duct damper on the carburetor and try starting again.

Let's start running in the lawn mower

After starting, do not rush to immediately break in the trimmer. Allow the engine to warm up at idle speed for 5 minutes. While warming up, adjust the air supply using the air damper lever so that the spool with fishing line or knife does not rotate. As soon as the tool has warmed up, we fully open the air supply by moving the corresponding lever to the “ON” position and squeeze the gas trigger 1/2 and hold for 20...30 seconds. Then we let off the gas and let the trimmer work for XX 30..40 seconds. We continue in this mode for 10…15 minutes. Then turn it off and let it rest for 15...20 minutes.

Having cooled the lawn mower, we continue to run in the engine according to the previous scheme. You need to start the trimmer when it’s hot, with the air damper already open. Try not to hold the gas for a long time, since the moving parts of the tool are only rubbing against each other. And don't let the engine run for too long. idle speed as it may overheat.

The next stage is running in the gas scythe gearbox. To do this, you need to choose an area with soft young grass. We mow for 5...10 minutes with throttle adjustments at 1/2...2/3 of full throttle. Afterwards we take a break for 20…25 minutes. We repeat the cycle 3…4 times.

In general, running in the lawn mower according to the described algorithm is carried out until the fuel mixture in the tank is completely exhausted. After which the tool is ready for long-term work. While working, keep an eye on temperature conditions gearbox and motor. They should not overheat.

What to do if your gasoline lawn mower won't start?

The most important point when using any equipment is compliance with the basic rules of operation and its timely service. This approach will ensure proper and long-term operation for you. gasoline lawn mower. But still, sometimes unforeseen situations happen, and for some reason the device does not want to start. In our article we will talk about possible reasons and ways to eliminate this problem.

Malfunctions that you can fix yourself

When your gasoline lawn mower does not start, first of all you need to check the presence of fuel in the tank. If it is missing, add it to the required level. Often when the device is not in use long time, gasoline “exhausts”, so it needs to be completely drained and refilled with new one. This procedure must be done carefully so that fuel does not get on the engine, as this can lead to further ignition (when the engine heats up). You can find out which gasoline is better to use from technical passport apparatus.

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

[Remmarket] How to do it right start up lawnmower

Two years of using the Chinese petrol trimmer HUTER for two-stroke engine brings one pleasure...

The problem may occur when incorrect location air damper during the first start. Depending on the air temperature, it closes completely or is set to the middle position (above +30 C). Then it must be opened completely.

Check air filter whether it is dirty. To do this, turn off the machine and disconnect the wire from the spark plug. Unscrew the cap and remove the filter. Wash it with gasoline and dry it thoroughly, or simply install a new one. Remember what to change air filter recommended after every 25 hours of use.

Another reason why a gas lawn mower won't start could be a faulty spark plug. Perhaps it was simply filled with fuel. In this case, unscrew it, clean it and check for a spark. It may be absent when filling the spark plug with fuel. Set the choke control (if equipped) to the CLOSED position and start the engine. If this does not help, it is better to seek help from a specialist.

The question of how to start the trimmer if the trimmer does not start or starts poorly will arise if the engine of the gasoline trimmer is worn out, unadjusted, or when, due to a violation of the sequence of operations when starting the engine, a lot of fuel got into the combustion chamber (when the engine was “sucked”). To help the engine start, you can pour a little fuel into the cylinder through the spark plug hole. For this, it is better to use a special starting fluid, but you can also use regular fuel from the tank of the trimmer or lawn mower being started.

How to start a trimmer by pouring 20 g of fuel into the spark plug hole

1. To start the trimmer (if the trimmer does not start), first of all, you need to check whether there is fuel in the tank and whether its level is sufficient (whether the fuel reaches the intake hose - whether the fuel filter is immersed in the fuel). It doesn't take long to open the tank cap and look inside.

2. Remove the cap and unscrew the spark plug using a spark plug wrench.

3. Next, you need to check and, if necessary, clean the spark plug electrodes from carbon deposits or other deposits using a metal brush or a thin screwdriver. The electrodes must be clean. When cleaning the electrodes, be careful not to damage the white ceramic insulator of the center electrode.

4. It is advisable to heat the spark plug electrodes on the burner gas stove or a lighter (following the rules fire safety). You can check the performance of the spark plug by inserting the spark plug into the cap and ensuring contact of the housing with the engine ground, and then cranking the trimmer engine with the starter and assessing the presence and quality of the spark between the electrodes of the spark plug.

5. Pour about 20 g of fuel into the spark plug hole using a tablespoon, cup or medical syringe. Then immediately replace the spark plug and tighten it.

6. Close the air damper (turn on the starting gas) and press the manual fuel pump button 3 times, pausing for 4 seconds. between each press.

7. Pull the starter handle several times and start the trimmer (gasoline mower) engine. As soon as the trimmer engine starts, immediately close the air damper.

8. If the engine does not start even after this, then you need to replace the spark plug with a new one, since this is most likely the reason (you need to buy a spark plug with the markings indicated in the trimmer/mower user manual).

9. If the engine still does not start, you need to clean the carburetor with carburetor cleaner.

10. To quickly clean the trimmer carburetor with carburetor cleaner, you need to remove plastic caps and an air filter to gain access to the carburetor (it is advisable to completely remove the carburetor from the engine and disassemble it). Spray a stream of carburetor cleaner several times into the central jet and into other accessible carburetor passages (through and through). This can be repeated several times to ensure that the channels are clean and free of debris.

11. It is necessary to check the spark-extinguishing mesh in the muffler of the gasoline trimmer/mower for contamination. If it is clogged with carbon deposits, this may be the main reason for poor engine starting and the mesh must be cleaned with a wire brush. The spark-extinguishing mesh in the trimmer muffler is designed to prevent hot particles from flying out of the muffler, which could cause a fire by falling, for example, on hay or other flammable materials.

12. How to start the trimmer, if after all that has been done the engine still does not start - you need to analyze if you pour 20 g of fuel into the cylinder, the engine starts to work for a short time, or starts, runs and stalls again, then the reason is in the carburetor, which or does not deliver fuel to the cylinder, or supplies little fuel, or mixes fuel in the wrong proportions. In this case, you need to either buy a new carburetor (it may be clogged), or take the trimmer carburetor for repair, or adjust the carburetor yourself. If, after pouring 20 g of fuel into the trimmer/mower cylinder, the engine shows no signs of life at all, then the reason is the spark plug, which needs to be replaced with a new one (buy a trimmer spark plug) or clean the old spark plug.

13. At the end of the season, you should always drain the fuel from the tank, both in the trimmer (gasoline mower) and in any other equipment with two-stroke engines. Pour the fuel from the tank into the bottle through a funnel, then start the trimmer to drain the remaining fuel from the carburetor until the engine stalls. If this is not done, then when stored for more than 1 month, the fuel will begin to separate into light and heavy fractions and the oil mixed with fuel during refueling will precipitate, which will lead to coking of the channels in the carburetor and, accordingly, to the trimmer coming out of service. building.

It is necessary to regularly check for contamination and change the fuel filter on time. fuel tank trimmer (petrol mowers). To replace the fuel filter, you can easily remove it from the tank using a wire hook. The fuel filter easily becomes clogged with bottom sediments in the fuel tank, which leads to a deterioration or cessation of fuel supply from the tank to the carburetor of the gasoline trimmer.

To refuel the trimmer, you do not need to use ethanol gasoline, since in small two- and four-stroke engines that are not used every day or at least every other day, this a big problem. Ethanol from gasoline precipitates and turns into resin or varnish, clogging the microscopic jets and carburetor channels.

To keep the carburetor clean and in good technical condition, you can buy a special fuel additive for two-stroke engines, which cleans the carburetor of tar deposits. The price of the additive is relatively small and it (the additive) is not dangerous.

Also, you should discard all old metal canisters, which will rust inside over time. Particles of this rust will cause clogged filters, jets and channels in the carburetor and, as a result, the inoperability of the gasoline trimmer (or lawn mower). Moreover, as a rule, the owner of the trimmer cannot immediately determine where this blockage comes from.

How to start a Husqvarna 333R trimmer

(procedure):

1. Pull out the choke on the engine (close the air damper).
2. Pump up fuel 6 – 8 times.
3. Hold the engine covers with your left hand (not your foot!).
4. Pull the cord handle lightly to free-strove the starter.
5. Pull the starter handle one or more times quickly to start the engine (just pull to such a height and with such force that you do not pull out the starter cord!).
6. Lightly lower the starter handle into place (do not drop it!).
7. Push in the choke (open the air damper).
8. The trimmer motor is running. You are smiling. Everyone else is in puppy delight!
9. After a few seconds, lightly accelerate to release the starting gas turned on by the choke.
10. We warm it up, if the engine is cold, for 3 – 7 minutes, depending on the air temperature, and you can mow.

Note: To turn off the engine, move the silencer button up (on the right handlebar).
IN initial position(to the Start position!) the key returns on its own. Therefore, to prevent anyone from starting the engine, it is sometimes better to remove the spark plug cap.

The advantage of gasoline lawn mowers

Main competitor gasoline lawn mowers are electric lawn mowers. The advantage of gasoline lawn mowers over electric ones is the following:

• Does not depend on the availability of a power source
• They have a more powerful engine, which allows them to work on large lawn sizes.
• More maneuverable, because Dont Have electric cable, which will trail behind and cling to all obstacles.
• A gasoline lawn mower can cut even regular, tougher grass.
• Cheaper to maintain (although they break down more often)

Despite this, gasoline lawn mowers have several significant disadvantages, namely:

• Making noise
• Assume additional material costs for fuels and lubricants (fuels and lubricants)
• Release of harmful exhaust into the atmosphere
• Requires repair and maintenance more often
• The engine is designed in such a way that when operating a gasoline lawn mower on hills steeper than 25°, oil stops flowing into the lubrication channels of the rubbing parts, as a result of which the lawn mower may break.

Recommendations for choosing a gasoline lawn mower yourself

Almost all the advantages and disadvantages various types petrol lawn mowers we have provided above, in brief description. But I would still like to draw your attention to some design features gasoline lawn mowers, which should be taken into account when purchasing a unit.

So, professional gardeners We provide you with the following recommendations for choosing a gasoline lawn mower:

• When buying a gasoline lawn mower, pay attention to the diameter of the wheels. The larger the diameter, the more maneuverable the unit will be, and therefore the more comfortable the process of mowing the lawn.

By the way, the width of the wheels should also be taken into account, because... narrow wheels will push through the lawn, leaving unattractive marks.

• The mower deck must be aluminum. In this case, the mower itself will be lighter, more resistant to mechanical damage and the formation of corrosion.
• If you choose a unit that is not powerful enough, the grass catcher should be plastic, because... It will be more convenient to clean the container from grass.
• Give preference to lawn mowers with folding rubberized handles. They are easier to transport and vibrations from the engine will be felt less.
• The mowing height should be adjusted by the central lever; this is more convenient and will allow you to cut the lawn more evenly throughout the entire area.
• Pay attention to the lawn mower’s executive body – the blade. It should be sharp and preferably wide. This version of the lawn mower will cut the grass more efficiently.
• Choose a gasoline lawn mower whose wheels are on bearings, because... conventional plastic bushings fail faster and are less resistant to mechanical damage.
• One cannot fail to mention the engine power. Based on the area of ​​your plot, choose an engine with a power reserve so that you can cut the grass in any weather. We draw your attention to the fact that self-propelled lawn mowers take up part of the engine power for movement; this also needs to be taken into account.
• Give preference to lawn mower manufacturers such as: Honda, Hitachi, Craftsman, Viking, MTD, Stihl, Husqvarma, Stiga, Makita, etc. Pay attention to the manufacturer of the gasoline lawn mower engine; the leaders are Briggs & Stratton and Honda.

Choosing a gasoline lawn mower

The gasoline lawn mower is the queen of gardening equipment. It’s simply impossible to do without it if you want your lawn to look well-groomed and attractive from the outside. When discussing lawns, one immediately recalls a story from Great Britain, where grass care has been a kind of state passion for several centuries. So, one day an inquisitive foreigner asked a British gardener how they managed to achieve the effect of a flawless lawn. “Sir,” replied the gardener, “all you have to do is just take the time to mow and water your lawn every day for a hundred years, and it will look exactly like the lawns in Great Britain.” And it must be admitted that the Briton is absolutely right, mowing the lawn, even if it is far from flawless in terms of the composition of the vegetation on it, turns it into an almost flawless greenish carpet, therefore the question “how to choose the right gasoline lawn mower” will arise for everyone at some point owner of his own plot of land. But why specifically gasoline, you might ask?

Advantages of a gasoline lawn mower

The main competitor to the gasoline lawn mower is the electric lawn mower, but despite the more low price The latest lawn mower using a gasoline engine as a unit has a number of advantages:

• Autonomy. Regardless of the availability of a power source, gasoline lawn mowers can be used anywhere and anytime.
• Mobility and maneuverability. The absence of an electronic cable that constantly interferes with the work is a significant argument in favor of a gasoline lawn mower.
• Power. Choice gasoline lawn mower very often justified by its power characteristics, which can be many times greater than the characteristics of an electronic lawn mower. This is a particularly important argument if it is necessary to treat vast areas of the lawn.
• Naturally, there will be skeptics who will remind you of certain shortcomings of gasoline engines, such as the greater weight of the mower, noise during operation and environmental pollution. All this is true, but you must agree that there are still more advantages than disadvantages.

Criterias of choice

How to choose gasoline lawnmower from the huge number on the market? To answer this question it will be useful to find out about the different varieties gasoline lawn mowers, which differ from each other in:

• Power;
• Mowing width;
• Type of grass catcher;
• Type of movement and multifunctional features.

These are only some properties, focusing on which you can perform conscious choice. Before you pick gasoline lawn mower, you need to evaluate the area where the grass cutting work will be carried out. The choice of lawn mower directly depends on its size, terrain, and the presence of trees and shrubs. So, for areas with difficult terrain would be better suited self-propelled gasoline lawn mower, and for a free, level area, suitable option there will be a mower with the largest cutting width, etc..

Self-propelled lawn mowers

All gasoline lawn mowers can be divided into two types: self-propelled and those that need to be moved by means of application. physical strength. The former, in turn, are divided into front-wheel drive and rear-wheel drive. Design feature self-propelled lawn mowers is the presence of a special drive on wheels, which assigns movement to the equipment and the user can only direct it in the desired direction. Such lawn mowers are especially good for large uneven areas, over which not everyone can push a heavy unit, and what’s more, with a full grass catcher. Most models of self-propelled lawn mowers can be adjusted to move at a speed that never exceeds the average walking speed.

Device with big wheels much more maneuverable, in addition, small wheels are suitable only if you have perfect smooth lawn, but if there are a lot of bumps and small holes on it, then you definitely need to opt for models with large and preferably wide wheels.

As for the height of grass mowing, lawn mowers are divided into three types, depending on the method of setting this very height. So, the first type includes lawn mowers with so-called individual adjustment, this is when the height is set on each individual wheel using a special lever. The second method is screw. In such models, the axle attached to the body is reinstalled. This method cannot be called easy and convenient, since it requires a lot of time and is quite complicated to implement.

The most convenient and quick way Set the desired grass cutting height - this is a central adjustment. The entire operation is performed with a slight movement of the hand, by pressing a special lever. Thus, without extra effort, you can set the required mowing height directly during work, if the landscape features require it.

Motor power

In the question “which gasoline lawn mower to choose,” engine power plays an important role. Here the choice depends on several factors. Obviously, it is enough for the site large area A powerful power unit is better suited, and not only because it will cope better and faster with tall, hard grass. And also because the resource is powerful engines more and if each trim requires a significant amount of time, then the service life of the motor comes to the fore.

If you choose a self-propelled model, then a significant part of the engine power will be directed precisely to moving the lawn mower, and if the power is not enough, then the lawn mower can, as they say, tear up the lawn rather than trim it. Especially if the grass is hard and the terrain of the area is uneven. On the other hand, the power of the power unit significantly affects the overall cost of a gasoline lawn mower. Therefore, you need to try to find the “golden mean”, when there is enough power and the price is not exorbitant.

Launch method

Today, the overwhelming number of new models of almost all famous manufacturers gasoline lawn mowers installs system manual start called ReadyStart, which does not require any additional manipulations, such as pumping fuel or closing and opening the choke, to start the engine. All you need to do is just sharply pull the cable and the motor will start working after one, maximum two attempts. It's even easier to start the engine if your lawnmower model is equipped with the InStart electronic ignition system, which allows you to start the engine with a simple press of a button. In this case, the lawn mower is equipped with a small battery.

When choosing a lawn mower, you also pay attention to the material of the body, which can be either plastic or metal. The best option counts aluminium case, which is practically not subject to corrosion and is lightweight. If you plan to frequently transport your lawn mower, you should pay attention to models with folding handles. This lawn mower can easily fit in the trunk of even a small car. And lastly, it is better to choose a lawn mower with wheels on bearings, rather than on bushings, which are found in some models.
