How to start a manual gasoline lawn mower. How to start a gasoline lawn mower. Let's start running in the lawn mower

Active exploitation garden equipment leads to rapid 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 lawn mower 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.

An average-priced mower can withstand climatic conditions St. 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.

Go on the road service center not worth it. Many problems can be solved with minimal costs 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.

Restoring the functionality 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 that the wires on the 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. 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 await 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 the presence 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.
There is contamination air filter. 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.

Don't know how to start a gas mower? We'll tell you. In any village summer cottage, country house for leveling lawn grass or weeds, cleaning the area in the garden or vegetable garden, you must have a mower and it is best if it is gasoline.

The crackling noise from using a gas mower can be heard from the first day of summer until late autumn, until grass growth has significantly decreased. Gasoline mowers have become extremely popular due to their ease of use. This device is easy to use and care for the lawn; if it breaks down, it is not difficult to repair. Below we will look in detail at how the process of starting a gasoline mower is carried out.

Refilling the fuel tank

Your first launch

When gasoline is poured and the rest fuel mixture Yes, the most crucial moment of the first launch of the gasoline scythe comes. In order for the first start-up of the mower to go smoothly, you must correctly follow the start-up instructions.

We are located on flat surface the brushcutter that we are going to start.
The choke control lever must be switched to the closed mode (position).
We make several pumpings of the primer so that gasoline fuel enters the carburetor.
Turn on the ignition button.
Try to pull the starter cord out smoothly until you feel a little resistance.
After which you can make several sharp jerks 3.4 and your lawn mower should start.
After this, you can open the air damper completely.

The process of first breaking in the mower

When you have started your device, do not rush to work with it right away. Give it time to work a little and break in. It takes about 5 minutes when you first start the engine to idle. While the engine is warming up well, you can adjust the air damper to prevent rotation of the cutting element with the spool. Once the mower has warmed up thoroughly, you can safely open the air supply completely and start mowing.

Press the throttle with slight force and hold it down for up to 30 seconds. Then you can release the gas and let your mower run again for longer, up to about 50 seconds. In this mode, you can work for up to 15 minutes without resting the device. Then we turn off our mower and give it about 20 minutes to rest.
Having cooled our equipment, we can continue to run in the engine according to the same scheme as described above. We start the trimmer on hot and always with the air damper open. Try not to hold it for long while working, because the parts moving inside the motor will definitely begin to rub against each other. At idle, the engine should also not be running, because it may overheat.

The next step is to properly run in the gearbox of our trimmer. To do this, you need to decide on a piece of grass; it must not be tall and young. We mow the grass for about 10 minutes, with gradual rests of the device as described above. The cycle is repeated at least 4.5 times.

Important! In general, running in a gasoline mower according to the algorithm described above should be carried out by you with a full tank of gasoline, but the last drop of the fuel mixture has been used up. After such a break-in, the tool will be ready for further, long-term work. When mowing grass, be sure to ensure that the temperature of the motor and gearbox is not exceeded. Both of these units should not overheat.

After mowing, it is advisable to no longer need to clean it. Since all the dried grass can stick strongly to it and it will be very difficult to tear it off. In addition to all this, the grass on the mower body will begin to rot and smell bad. Therefore, our advice to you is that after each mowing, it is advisable to clean the mower completely from dirt and remaining grass.

It is also impossible in winter time leave gasoline in the tank. During storage, gasoline can thicken greatly and damage your carburetor.
Can't run petrol mower without appropriate lubrication after storage, unless you have the desire to constantly buy a new device.

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

For a comfortable work process and no breakdowns during operation of the lawn mower, like another garden equipment similar action: trimmers, brush cutters, 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 filled fuel and fuel mixture are of high quality and in the required quantity, 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 lawn mower makes a popping sound and stalls, there is a problem with the ignition, and you cannot do without a service center.

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 are not confirmed, and the lawn mower still stalls, you can remove the air filter and try to start the machine without it. If a stalled engine starts, this is the cause. 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 highly not recommended to operate a lawn mower without a filter element.

Breather contamination. It helps regulate the pressure in the gas 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 with carburetor problems include:

Contamination 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.
Damage to seal. 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.

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 required quantity fuel into the carburetor, so there is no need for additional manipulations - 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.

When using any equipment, the main thing is to handle it carefully and follow the operating rules. In this case, the device will serve you faithfully for a long time. However, it still happens that the tool breaks. Of course, you can entrust the matter to professionals and take it to a service center. However, you can often fix the problem yourself. In this article we will explain what to do if lawn mower won't start.

Why won't my lawnmower start?

The answer to this question depends on which model you are working with: gasoline or electric.

Key points to consider when working with a petrol model:

1. Before starting the lawn mower, you first need to check the availability of fuel. Please note that you should not pour fuel to the brim. Usually the tank has a maximum fill mark. You need to pour gasoline carefully, preferably through a funnel. If fuel gets on the engine, it can cause a fire or even an explosion when heated. Over time, the gasoline left in the device “exhausts.” Therefore, it is recommended to drain it in the winter.

2. You need to start the device correctly. When starting the lawn mower, set maximum speed and prime the carburetor with fuel. Smoothly pull out the starter cord to maximum length and pull it towards you with a sharp movement.

3. Another reason why a lawn mower won't start is often a faulty spark plug. In this case, it must be cleaned or replaced. Remove the candle from the device. If there is plaque on it, blow it out or replace it with a new one. After installing the spark plug in place, close the air damper.

4. A dirty air filter can also cause starting problems. Turn off the device and disconnect the wire from the spark plug. After removing the filter, rinse it thoroughly with gasoline and dry it. The operating instructions recommend doing this after every 25 hours of operation.

5. If the lawn mower stalls immediately after starting, most likely the reason is a stuck piston or crankshaft. Carefully move these parts and the problem may be resolved.

6. Also, do not forget to check the oil in the crankcase. An insufficient amount of it may cause the lawn mower to not start.

Information for owners of electrical equipment

1. If you use an electric lawn mower, you should make sure that the cord is connected before starting. It is also worth checking the electrical panel. The circuit breaker may have switched off or the fuse may have blown.

2. There is a possibility that the lawn mower does not start due to thermal protection. Check the ventilation grilles: is there grass clogged there? Clean them if necessary and allow the engine to cool.

3. Another reason why a lawn mower may not start is a broken switch. In this case, you need to take the tool to a service center.

As you can see, in many cases problems can be fixed without the help of a specialist. The main thing is not to replace parts yourself. In such cases, it is better to trust the professionals.
