We choose a gasoline lawn mower. Features of choosing a gasoline self-propelled lawn mower.

Choosing a gasoline lawn mower

Gasoline lawn mower - queen garden 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 lawn mower 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 flat 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.

Apparatus 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 fast 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. 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.

Active exploitation garden equipment leads to an early failure of individual components or parts. There is no need to dispose of the equipment, as it can still be useful in the future. After all, sometimes by doing a little repair on the lawn mower with your own hands, you can return it to its previous working condition.

When the lawnmower won't start

Depending on the area of ​​the lawn and the growth of the grass on it, the owners choose the equipment that has the optimal characteristics. It comes in several types:

• gasoline devices;
• units with an electric motor;
• battery powered equipment.

Average price mower withstands climatic conditions Petersburg, Moscow or similar regions for about four seasons. More expensive or less used garden helpers capable of withstanding field conditions 5-6 seasons.

Do-it-yourself restoration of lawn mowers will also be required if the conditions winter storage turned out to be inappropriate. For example, work surfaces were not cleaned after use or there was no off-season preventative maintenance. This results in a variety of problems:

• frequent sharpening of lawn mower blades is required;
• The lawn mower just won't start;
• the engine starts, but after a short period the lawn mower stalls;
• malfunctions appear in the carburetor, which requires not only disassembly, but also cleaning and repair;
• Do-it-yourself lawn mower repair is required when there is a significant decrease in power during operation.

There is no need to go to an expensive service center. Many problems can be solved with minimal cost and carry out the repairs yourself.

After each use of the tool, it is necessary to clean the cutting elements. Change the oil regularly and carry out maintenance to minimize the risk of breakdowns.

Restoration of operability of electrical equipment

Mowers that have electric motors inside most often begin to act up due to oxidation of the contacts. The terminals become covered with a layer of scale from excess humidity in the room or other storage location. It is also worth checking the absence of wire breaks on problem areas. For this operation, use a multimeter or other type of tester.

When a set of garden equipment contains a brush motor, we determine the functionality of the moving unit. The brushes can wear out quickly, resulting in a lack of contact. A repair kit with them costs relatively little, and is easy to find in specialized stores that sell spare parts for such equipment.

Malfunctions lie in wait and asynchronous motors. They are denied phase-shifting capacitors. This situation is difficult to diagnose at home. It can be identified by indirect symptoms:

• a buzzing sound is heard;
• when starting, the body twitches slightly;
• the motor heats up significantly even under light load;
• speed decreases.

It is worth diagnosing the state of the turning on toggle switch/button and the voltage supply to the electric motor. When the described components have been tested and no malfunctions have been found, it is unlikely that you will be able to fix the broken lawn mower yourself. Then you will have to use the services of a branded service.

Main problems with gasoline cars

Primary diagnostics is carried out from the stage of eliminating the most obvious breakdowns. When the engine does not start, it is worth checking the presence of fuel in the tank. If there are any leftovers from last season, then it is worth replacing it. After wintering, low-quality gasoline can lose its characteristics, give an unwanted sediment, or even separate into fractions based on density. In this form, it is not able to start the engine, but will only clog the system.

At the second stage, we find out why the spark does not appear. Its loss will prevent the fuel from igniting. We remove the cap from the spark plug and unscrew it from the seat using the special key that came with the mower. Next, we put the cap on the candle, bring it closer to the threaded part or metal element engine, and at this time the partner pulls the starter.

With such manipulations, a powerful blue spark should appear in the working unit. It can be noticed even with daylight. It is important to test this next to unpainted metal part motor capable of conducting current.

When there is no spark, you need to go for new candle to the store. Do not return it to the engine even if the spark is weak or unstable. It is better to first clean the working contacts on the head from carbon deposits.

During operation, rattling may occur in the structure. At first, it does not affect the performance of the mechanism as a whole. However, it can lead to imbalance and increased noise during operation. It is worth tightening the fastening bolts on the frame in a timely manner.

An uneven cut in the grass is an indication that your lawn mower blade needs to be sharpened. Getting to them is not so difficult, but it is important to completely disconnect the equipment from the power supply. You can do the work yourself using yews and a file or using sharpening sandpaper. It is important to ensure a uniform cutting angle along the entire line of 30 degrees. If there are chipped areas in the surface, this is evidence of contact with a hard surface. Replacing them will be quite expensive.

After switching on, a whistling sound appears. An unpleasant acoustic effect is associated with the penetration of foreign elements into the structure. They can block the roller in the aerator. You can solve the problem by turning off the blocked roller and then removing the foreign object.

The engine of gasoline equipment becomes almost immediately after starting short work. The culprits are a seized crankshaft or piston. At the same time, check the presence of oil in the crankcase. With the engine turned off, manually start the rotation or add oil as necessary. However, in such a situation you often have to turn to specialists for restoration.

Problems with the carburetor and fuel system

Before you start repairing the lawn mower engine, it is worth checking whether the pistons are stuck. To do this, it is necessary to dismantle the motor. We also remove the carburetor from the structure and carry out a visual inspection for possible defects. Typically, disassembly will require a special TOREX screwdriver with bits.

We inspect the gaskets to identify ruptures or burnouts. If this is found, then you need to ensure the tightness of the structure by replacing them with new ones. The air damper may contain a layer of carbon deposits, which reduces the quality of the air-fuel mixture. You need to get rid of it by cleaning the carburetor by washing the unit in solvent or kerosene.

Choking during operation or failure to dial them to enter operating mode, together with overheating of the power unit, are the causes of the following events:

• Violation of idle speed control. You can use a screwdriver to unscrew the jets to the correct position yourself. You can do this even by ear so that the motor runs smoothly. The knives do not need to be removed, but they should not rotate.
• The air filter is dirty. It is enough to take it out and clean and rinse. We dry it naturally in the wind, without placing it near the stove or fireplace.

Remove the carburetor fuel chamber cap and clean it. An ordinary Vedashka is quite suitable for this, but you can also buy a special liquid

To clean the fuel chamber, first wipe it with WD-40, then soak it for 15-20 minutes, and wipe it again. This needs to be repeated 3-4 times to completely clean the chamber and channels.

A clogged exhaust causes a narrowing of the exhaust pipe's output flow. Resins appear on inner surface due to incorrect ratio of fuel and oil mixture. We twist the crankshaft so that the piston goes up to the maximum and clean its surface with a wooden stick.

In more serious cases, it is recommended to contact the warranty service. Otherwise, unprofessionalism will cause more damage. Moreover, when independently searching for malfunctions and repairs during the period warranty period, the warranty is no longer valid.

One of the problems that users often report with gasoline-powered lawn mowers is the difficulty of starting due to the need to pull the rope several times. To make starting the equipment easier and no longer experience difficulties with it, it makes sense to take a closer look at mowers whose engines have an easy start function. For example, Briggs and Stratton engines have two versions of this option:

ReadyStart - guaranteed start of a cold engine with one or two pulls of the cable. The system independently determines the engine temperature and supplies the required amount of fuel to the carburetor, so no additional manipulations are needed - pumping fuel and closing the air damper. If at normal use and storage of equipment, the engine does not start after two jerks, the manufacturer undertakes to repair it free of charge.

InStart is an electric starting system using a rechargeable lithium-ion battery. A starter cable is no longer needed: the engine starts by simply pressing a button or turning the ignition key, without suction or pumping fuel. The battery is fully charged within 60 minutes - this is enough for 50 starts; It can be quickly charged in 10 minutes, which is enough for 10 starts.

Quiet operation of the mower

The idea of ​​gasoline mowers as noisy machines is completely outdated. Modern mufflers reduce noise levels to a minimum and are designed in such a way as to relieve the user of the high-frequency component of sound, which is perceived by the human ear as the most annoying. Working with such equipment does not cause concern either to the user or to the neighbors.

Easy maintenance

Most modern gasoline mowers are equipped with overhead valve engines (the abbreviation OHV is usually stamped on the body). This constructive solution reduces the amount of emissions and the degree of heating during operation. This not only increases the durability and reliability of the equipment, but also facilitates maintenance: the oil temperature in an overhead valve engine is approximately 20% lower than in a conventional engine, so it loses its properties more slowly. The latest generation engines with tool-free air filter replacement, a high oil filler neck and technologies that increase oil service life make the maintenance procedure quick and easy for any user.

Convenient storage

Space for storing garden equipment is usually very limited, so compactness is an important quality for a lawn mower. From this point of view, the Mow N’Stow technology is interesting: a mower equipped with an engine with this option can be stored in vertical position without fear of gasoline and oil leaking. Simply fold the handle, place the mower vertically and lean it against the wall. This saves up to 70% of the space that it would occupy if the usual way storage

Eco-friendly mowers

Side effect of work gasoline equipment- emissions unsafe for environment. Users are also familiar with the problem of fuel evaporation from an idle engine, which creates certain difficulties with storing gasoline-powered equipment. Engine manufacturers are constantly improving technologies to reduce these unpleasant phenomena to a minimum. Nowadays, new garden equipment has appeared on the market, equipped with engines with record low emissions. In addition, these engines eliminate the problem of fuel evaporation when idle.

It should be noted that the lawnmower engine can be equipped with a range of technologies that simplify its use and maintenance. This makes the equipment somewhat more expensive, but the costs are justified due to greater comfort during use. Engines with a number of the listed functions are installed on models of gasoline mowers from such reputable manufacturers as Husqvarna, MTD, AL-KO, etc.

EXPERT ADVICE

Victor Danilov, technical specialist at the Moscow representative office of Briggs and Stratton

Trained users who purchase a new gasoline mower to replace an old one call the presence of an easy start function a determining factor in their choice, since they know firsthand what it’s like to repeatedly pull the cable in attempts to start the engine. Therefore, if you are purchasing a lawn mower for the first time, it is better to immediately give preference to a model with an easy start. And in order for it to serve you as long as possible, be sure to perform it in a timely manner. Maintenance, following the instructions in the operating instructions.

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 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.

Despite quite wide choose lawnmowers with different principles work, do not lose their popularity petrol mowers. They have earned respect among users for their power and autonomy.

For a comfortable work process and the absence of breakdowns during operation of a lawn mower, as well as other garden equipment of a similar function: trimmers, walk-behind mowers, the first start is very important. If you do not pay enough attention to preparing equipment for use, this may affect the quality of work or lead to damage to the unit.

Starting the lawn mower

Before starting a gasoline lawn mower, you should conduct a visual inspection for visible damage. The process of starting the unit is conventionally divided into several stages.

Preparing the fuel mixture, refueling

If the lawnmower is started after winter, the contents of the tank are checked: if there is unused fuel, it should be drained. Then you can start refueling the equipment. It is important to know some nuances here.

For refueling two-stroke engines it is necessary to use a fuel mixture. It can be purchased at finished form or cook it yourself. There is nothing complicated in preparing the mixture, but you need to adhere to the required proportions.

Petrol lawn mower Oleo-Mas

When using synthetic oils, a proportion of 1:50 is used - for 5 liters of gasoline 100 g of oil.

Using mineral oils the proportion is 1:35 - 100 g of oil per 3.5 liters of gasoline.

Refueling a four-stroke engine does not require preparing the fuel mixture. There is a special sump for oil; gasoline is poured separately. It is important to remember that the oil also requires changing, depending on the intensity of use of the lawn mower. Basically, you need to change the oil every 50 hours or at least once a year.

Important! Lawn mowers perform well when using oil with a viscosity index of SAE-30. In addition, if the engine was run in with synthetic oil, it cannot be replaced with mineral oil in the future and vice versa.

As for gasoline, lawn mowers made in China, Japan and America work well on A-92 fuel; for European models it is better to use gasoline with a high octane number.

When refueling the mower, you need to ensure that the gasoline level is 2-3 cm below the edge of the fuel tank.

Starting a cold engine

Before starting a cold lawn mower, the transmission and ignition system are turned off, and the motor shaft is cranked with a starter or starting cord.

If the lawn mower does not start, you will have to carry out a number of other manipulations:

• The throttle remains closed, the ignition is on;
• Press the fuel pump (choke) button about 5 times;
• An attempt is made to start the engine.

In case of repeated failure, you should:

• open the damper to prevent the spark plugs from flooding;
• turn the shaft with the starter;
• blow out the combustion chamber;
• start the engine.

Sometimes it may take about 15 jerks to start the engine for the first time - this is quite normal for this technique.

When the engine starts, squeeze the throttle lever once to use idle speed. Next, the lever is set to the position corresponding to low speed. In this position, the engine must run for about 5 minutes to warm up. If necessary, its operation can be stopped by pressing the “Stop” button.

Starting a warm engine

Starting a preheated engine is much easier and does not require such effort:

• the control knob is set to the “maximum fuel supply” position;
• the engine starts;
• the desired speed is selected.

You can start working.

Errors at startup

The most common mistakes when starting a gasoline lawn mower are:

Major breakdowns of lawn mowers

Despite big choice manufacturers and variety of models, the reasons why a Makita, Honda, Husqvarna or other lawn mower does not start are the same for everyone.

The main reasons why a gasoline lawn mower does not start or starts but immediately stalls may be problems with the ignition, carburetor, or filters.

If the fuel is filled and fuel mixture high quality and in the right amount, the air damper is closed, The lawn mower starts and immediately stalls; the reason may lie in the following problems:

• Faulty or flooded spark plug. In this case, you should unscrew the candle, dry it well and thoroughly clean it with a nail file or file. Excess fuel is drained and the spark plug hole is dried. A gap of 1 mm is set, and the spark plug is screwed in again.

Important! It takes at least half an hour to dry the canal.

• Dry threaded connection. It should be lubricated with gasoline so that the spark can ignite.
• No spark from the spark plug. In this situation, the contact between the spark plug and the high-voltage wire is first checked. If the contact is normal, but the lawnmower makes a popping sound and stalls, there is an ignition problem, and without service center not enough.

These breakdowns are common reasons, why the Husqvarna lawnmower does not start.

Quite common causes of breakdowns of garden equipment, including why a Honda lawn mower won’t start, are problems with the air and fuel filter:

• Clogged air filter. If the first possible reasons have not been confirmed, but the lawn mower still stalls, you can remove the air filter and try to start the machine without it. If a stalled engine starts, the reason is in it. The filter should be cleaned or replaced with a new one.
• Dirty fuel filter. Another possible variant diagnostics The filter element is inspected and replaced if necessary.

Important! It is not recommended to operate the lawn mower without a filter element.

• Breather contamination. It regulates the pressure in the fuel tank. If the breather is blocked, a vacuum is created and the fuel supply stops.

The following breakdowns are more serious and will not be easy to deal with without certain skills. Problems are in carburetor malfunctions:

• Pollution of jets and channels. They are washed with special liquids and blown with a stream of air from the carburetor.
• Worn gasket. It is being replaced with a new gasket.
• Sealing damage. Diagnosis is carried out using a tonometer. If the pressure is stable, everything is fine, if it drops, you need to find and replace the damaged element.

Another possible breakdown is a malfunction piston group. Worn or damaged pistons should be replaced.

Rules for operating a gasoline lawn mower

Like any equipment, a mower requires some special care and compliance with the basic principles of use. These rules are simple, but will help maintain the functionality of the unit for a long time.

General operating rules:

• Read the instructions for using and caring for the lawn mower, learn the basic rules of operation, storage and safety precautions.
• After each use, clean the body, channels, grass catcher, knives, preferably using special liquids.
• Do not clean the lawnmower with a hot engine.
• During operation, monitor the condition of the engine, do not let it overheat, and take breaks.
• For long intervals in operating the lawnmower (about a month), drain the fuel. At the end of the work, the device is given the opportunity to idle and stall.

Rules for preparing equipment for winter:

Safety regulations:

• Before starting work, check the work area for the presence foreign objects: stones, branches.
• No strangers are allowed within a minimum distance of 5 m from the lawn mower.
• The work is carried out in special glasses.
• A visual inspection of the lawn mower is carried out for damage and loose parts. Malfunctions are eliminated.
• You can mow grass no higher than 20 cm, no more than a third of it at a time.
• When working on slopes, you should move along the slope, not up and down.
• The motor stops before changing the bevel height.
• If foreign elements get into the mower blade, the work stops and the blade is cleaned.

Gasoline lawn mowers have earned the respect of users for their power and quality of work. In order to extend the durability and performance of the unit, you need to learn all the intricacies of care and maintenance of the lawn mower, follow safety rules, and adhere to the operating instructions for this equipment.
