Petrol or electric lawn mowers, the choice is yours
There are two types of lawn mowers on sale today. These are electric lawn mowers and gasoline ones. If you need to mow the grass far from home, then it is best to use gasoline technology. The advantage is that the petrol lawnmower is not dependent on electricity. The engine is absolutely unaffected by long-term operation of the lawn mower.
The mowing speed of a petrol lawn mower is much faster than an electric one..
Before starting your petrol lawnmower, you need to make sure that there is fuel in the tank, and most importantly, there is engine oil. If there is no oil, the engine will jam. In this case, you will have to spend a lot of money on repairs..
Electric lawn mowers are considered more economical and quieter. However, there is a clear drawback to electric lawn mowers – it is not mobile. And it is limited by the length of the power cord. You need to constantly be near the outlet. Moreover, during operation, the wire is often confused, it has to be corrected.
Before turning on the electric lawnmower, you need to check if the power cable and the socket itself is intact. Under no circumstances should the electric lawnmower be used during rain or dew. This technique can only be used on dry grass..
Good care of your lawn mower is the key to its long-term use
It should be noted that the lawn mower is a versatile and one of the most convenient machines that is used for gardening purposes. Thanks to the use of a lawn mower on the site, you can create an unusual landscape design. A lawnmower can be called a highly specialized unit, as it can only mow the lawn. Nevertheless, it is the lawn mower that becomes the best assistant for summer residents, owners of suburban areas. In municipal services, lawn mowers are required. With their help, parks, squares are always maintained in proper form..
When buying a lawn mower, special interest and attention are always shown to it. Remember not to overload the mower. The machine needs care, cleaning with your own hands. However, over time, the lawn mower still becomes a common tool for work, which is paid little attention..

How to sharpen a knife in a lawn mower
First of all, we will tell you how to sharpen knives on lawn mowers. Let’s say right away that the principle is the same on gasoline and electric devices. First, turn off the power to the mower. Then we put the device on the brake. The protective cover is removed. After turning the mower on its side, wear rubber gloves or other gloves to avoid injury. Use a brush to remove dirt and grass from visible parts. Then we remove the knife and fix it in a vice. Now you can start sharpening the knife with a file. If the knife is bent during operation, then it is necessary to align it. To do this, put the product on a flat surface and level it with a hammer..
Watch a helpful video on sharpening lawn mower knives
Once all the work is done, you can put it in place. Most often, knives begin to sharpen in the spring, when there will be the first mowing. You don’t have to sharpen the knife during the season.
According to the words, everything is so simple, but when a person who does not understand anything in this matter is taken to work, many difficulties immediately appear. It is best not to do the work yourself. Entrust it to specialists. Improper sharpening will result in the knife being thrown away. In order to remove the knife from the mower, you must use a socket or box wrench. It is not necessary to retighten the bolt too much, since you will have to unscrew it again later. Not only that, the force will cause the thread to be ripped off..
How to care for your lawn mower
The inside of the mower cover must be cleaned after each mow. The grass that collects on the device can not only interfere with further work, but also cause a fire. Do not use chemicals to clean the mower. This may damage some parts. If you wash some parts with water, then you need to wipe everything dry very well then. As soon as a little paint lags behind the metal, corrosion will immediately begin.
There are such modern models that have a fitting available. A hose is connected through it. The water turns on, the mower starts up. While the knife is rotating, it is washed..
All lawn mowers have air-cooled engines. To keep the engine from overheating, you need to constantly clean its fins on the radiator. In order to clean the motor, it is sometimes necessary to dismantle some parts. A great way to clean your engine is to use a compressor that supplies compressed air..
Fuel quality affects engine performance and performance. After the last use, you need to drain the gasoline from the gas tank. Best of all, when it is all worked out. So, it is necessary to crank the starter so that all the valves close. So we leave the technique until next season..
Sometimes the engine oil and spark plugs are changed on lawn mowers. The oil is changed when the manufacturer requires it. Only special oils are used in terms of viscosity and grade. There are engines where the lower compartment opens to drain the oil, and it also happens that you need to turn the mower on its side.
It is better to drain the oil immediately after work. Then precipitation will not have time to form in the crankcase, and the viscosity of the hot oil is much lower..
If the candles are corroded or burnt out, then you need to replace them. You can simply clean the candles, but it is better if a new one is installed. The air and fuel filters also need to be cleaned and in some cases replaced..
Operating rules for gasoline and electric lawn mowers
The operating rules for gasoline and electric lawn mowers are approximately the same. You always need to follow the rules that are clearly spelled out in the instructions from the manufacturer. It is important to pay attention to the moment when you need to take a break from the device. For example, if the engine overheats on a gasoline lawn mower, this will lead to its failure..
After each working process, it is necessary to remove the remnants of grass from the knife and other equipment parts. The mower should be stored in a dry place where it will not be threatened by precipitation. As soon as work with garden equipment ends, it must be turned off so that there is no threat to the health and life of your loved ones. When the device is running, it is impossible to inspect the equipment. If you find any problems, then you need to contact the service center, where you will be provided with qualified assistance. A problem that is identified in time will allow you to avoid expensive repairs in the future.
If a very large and thick grass has grown on your site, then you cannot mow it at a time. You need to walk the lawn mower several times. The grass must be removed gradually so that the mower does not overload..
In order for the knife not to dull when hitting the ground, you need to avoid unevenness in the area. In order for the lawn to be cut beautifully and correctly, you need to carry the device only forward. To prevent the lawnmower from harming you, you must wear protective clothing and shoes. The mower is not used where there are stones, curbs, debris. All this can lead to damage to a working lawn mower..
Now is the time to talk about how to use the lawn mower correctly, as well as how to properly repair and service it..
Storing the mower
The lawn mower should be stored in a closed and dry area. Moisture, snow – all this is unacceptable for technology. Make sure that no children or animals are approaching the mower. Only a dry and clean lawn mower is sent for storage.
Before mowing the grass, you need to check that there are no bricks, metal or glass on it. Otherwise, the knife may break and the engine will jam. Replacing the knife is not a problem, but replacing the motor is not a cheap pleasure.
It is best to operate the mower when the grass is dry and it should not rain outside. If the mower is powered, you can get an electric shock. If a gasoline lawn mower, then if water gets on the filter, the device will fail..
How To Adjust The Carburetor On Your Lawn Mower For Optimum Performance?
This is a very delicate matter – adjusting the carburetor, not every master will be able to adjust it by ear, you need to look at the adjustment on the tachometer and, based on the readings, adjust the optimal speed.
The carburetor is regulated in each lawn mower according to different parameters, so in order not to mislead you, I will omit the numbers and just tell you the basic adjustment diagram:
First, the engine starts and warms up, then the speed is adjusted to a certain speed by tightening the nozzle adjusting screws (if you get in there at least once, until you adjust the entire carburetor, the lawn mower will not work properly)
So, having set the revolutions with the jet by adjusting the fuel supply to a certain speed, we proceed to adjusting the idle speed, for this we also take readings from the pressure gauge and adjust it in accordance with the technical data of the tool.
In some models, the enrichment of the mixture is regulated by two screws – low speed and high speed, while the low speed is controlled first..
At the beginning, I would like to note some important things..
The carburetor is adjusted for optimal operation at the factory, if there are no problems with the lawn mower and with the carburetor in particular, then there is no need to adjust anything additionally.
Carburetor adjustment is done using instruments such as a tachometer
This work requires a lot of experience, carburetors (professionals), even in an average city, can be counted on one hand.
Lawn mowers are different, carburetors are naturally the same.
If you still decide, then at the beginning you need to perform a number of actions.
Change the candle, change the air filter (you can just clean it), eliminate other “little things” that can affect the operation of the entire apparatus.
Only after that we proceed to adjust the carburetor.
Naturally, the lawn mower needs to be driven a little, the carburetor is not regulated on a cold.
Next, look at your carburetor, maybe you have three screws there (there are other options), the screw marked “L” is responsible for low rpm.
Jet “N”, for high speed.
“T”, idle speed (marking may be different, you must look exactly at your instructions).
At the beginning we adjust the jet “L”, slowly turn the screw slightly to the left and right sides, looking for maximum idle speed.
As soon as they found the same screw was turned a quarter of a turn counterclockwise and so far.
Now we adjust the idle screw, everything is clear here, we increase the speed clockwise, we decrease it counterclockwise, our task is to make the lawn mower work steadily even when it is cold.
We will follow the adjusting the screw of high speed.
The throttle is completely on ourselves, as soon as we hear that the revolutions have reached their maximum value, we turn the screw (again slowly) counterclockwise, we hear that the revolutions are not stable, now clockwise until the engine starts to work steadily.
That’s basically all, but I still advise you not to adjust the carburetor yourself.

How to properly clean and adjust the carburetor
Quick check of carburetor functions. Carry out the following checks, air filter inlet heating system.
Heated intake manifold (hedgehog), throttle body, thermal switches and – thermal valves, idle solenoid valve – turn on the ignition. Disconnect – supply wire – clicks should be heard when the valve is actuated.
Accelerator pump – press the pressure lever with the throttle valve – a continuous continuous jet should be emitted from the sprayer.
Partial load valve (economizer)
trigger control diaphragm – check for air leaks
automatic machine spring – pump, trigger and starting parts
air damper – check the smoothness of opening.
Without diaphragm – check for gasoline leaks and replace defective parts.
Throttle Accuracy and Fit – Check for Wear.
Secondary Throttle Actuator – Check for Excessive Wear.
Check the CO level, if possible, in the exhaust gas at idle. If the CO level is out of range, try to adjust it. Please note where the result will be within the permissible specifications – the mixture will be enriched or depleted. Check CO and CH levels at 2000 rpm. min. At these speeds, the CO level should be approximately 50% lower than at idle. Remember which result will be obtained – rich mixture or poor.
Check CO and CH levels at 3000 rpm. min. At these rpm, the CO level should be slightly lower than at 2000 rpm. min. Again, remember at what quality of the mixture the result was obtained..
Open the throttle quickly at 1000 rpm. Watch for possible failures in the engine and the operation of the accelerating pump, pay attention to the CO level – if it falls, then there is no enrichment of the mixture, if it rises, then the mixture is enriched correctly.
Check the ability of idle to recover (when the throttle is released).
The results of the obtained analyzes of the composition of the exhaust gases should indicate the nodes of the carburetor responsible for the enrichment or depletion of the mixture..
It is hardly a rarity – hanging of the slightly open throttle valve of the secondary chamber at idle speed. This often causes a very rich mixture, gasoline leaking out of vias or crevices. Black soot from the exhaust pipe. This is due to the formation of a carbon ring around the secondary throttle valve, which prevents it from closing completely against the stop in the adjusting screw. The screw is adjusted so that the flap is closed but does not get stuck in this position.
Dips or uneven operation of the engine
Check the ignition system and spark plugs thoroughly.
Check the ignition timing at idle, make sure the vacuum and mechanical ignition timing are working properly.
Check the operation of the accelerator pump.
Check for air intake.
Adjust the carburetor to a slightly richer mixture than specified in the Specifications.
Carry out a gas analysis of the exhaust, paying particular attention to CO at 2000 rpm. min and 3000 rpm min.
If the gas analysis results are significantly greater or less than the permissible specifications, service the carburetor and check the cleanliness of the jets..
HOW TO Gap a Coil / Magneto on a BRIGGS and STRATTON LAWNMOWER Engine. ALL Models
If the mixture is too lean and after servicing, change the idle jet or the fuel jet of the main metering system to a slightly larger one..
Cold start and warm-up problems
Check the condition of the intake air heating system. Make sure that all vacuum hoses are properly connected, the integrity (or presence) of the corrugated hose for heating the air from the exhaust manifold to the air cleaner body. The air damper in the air cleaner housing should be open to allow hot air to enter at air temperatures under the hood below 15 ° C (usually) and gradually closed with an increase in the engine compartment temperature. Hot air access in most systems should be closed at temperatures above 25 ° C. If the action of the damper is broken, check the operability of the thermostat of its actuator, which is usually installed in the air cleaner housing..
Let the engine cool down, remove the air cleaner and move it to the side with the vacuum hoses attached.
If a semi-automatic suction is installed, cock the system by lowering the throttle by smoothly pressing the accelerator pedal a couple of times.
The flap should close off the carburetor inlet. If not, check the connection of the bimetallic spring to the choke control lever. Adjust the spring to close the choke when the engine is cold. If the spring housing is turned all the way down and the flap is still not closed, the spring may be defective. It can also be the reason for the incomplete opening of the damper with the engine warming up. There is a way out – replacing the spring.
Start the engine.
Make sure the starting speed is correct..
The mechanism for opening the dampers during cold start should work as expected..
With the engine warming up, the throttle should open slightly and the speed should gradually fall to idle. It may be necessary to stimulate the opening of the choke by lightly depressing the accelerator pedal and releasing it to release the crank cam.
If the operation of the actuator is not satisfactory, check for a jam, wear, or damage to the actuator. Also check for electrical heating and heating from the cooling system. If the engine stalls immediately after starting, or barely turns, try to change the angle of the throttle position with your finger. If the engine runs more fun, check the trigger adjustment. If the adjustment is within the prescribed range, adjust the mechanism so that the starting system works satisfactorily. Many engines require a leaner or, more often, a richer mixture with age..
Checking the thermal switches in the cooling system
Thermal switches provide power to components such as the choke switch, intake manifold heating and throttle body heating when the engine coolant has not yet reached operating temperature. When the engine (and, accordingly, the coolant) reaches the operating temperature, the switches are triggered and turn on the power. One switch must serve several components, each component can be operated from one switch. The switch is usually installed in the coolant hose or in the intake manifold cooling channel. In some systems, the heating of the throttle and the control of the machine does not depend on the thermal switches
All circuits are different, so in each case, refer to the wiring diagram of a particular car.
Heating of the intake manifold is usually carried out using a relay controlled by a thermal switch, connected to the “minus” terminal of the relay winding. The engine is warming up – the switch opens, the relay is de-energized – the heating is turned off.
Both manifold and carburetor heaters operate on the principle
positive temperature coefficient of resistance, with an increase in temperature, the resistance of the heater increases, the current decreases.
A quick check of the heaters is possible if you turn on the ignition and touch the intake manifold or the throttle body with your hand; they should heat up quickly. Be careful to avoid burns. On a warm engine, these parts should not overheat..
On a cold engine, turn on the ignition.
Connect a voltmeter between the carburetor ground and the thermoswitch hot wire. If the battery does not supply power, check the connection of the carburetor body to the negative battery, then power from the ignition switch to the switch.
Connect a voltmeter between the switch executive contact and ground. If there is no power, replace the switch.
Now connect a voltmeter between the heating element supply lead and ground. If there is no power, check the wiring from the switch to the element.
Start the engine and warm it up.
Connect a voltmeter between the thermal switch executive contact and ground. When the engine reaches operating temperature, the voltage at the operating contact of the switch should disappear. If not, replace the thermal switch. If the trigger temperature of the switch is unknown, it should trip when the engine is fully warmed up..
The thermal switch can also be checked with an ohmmeter. An open thermal switch should indicate infinity, a closed one – zero.
If all voltages are present, and the system does not work, check the quality of the connection between the carburetor housing and the negative battery terminal.
Disconnect the electrical connector from the choke machine.
Connect a test lamp between the positive terminal of the battery and the terminal of the suction heating element. If the lamp does not light, replace the “suction” heating element.
Heated intake manifold
Connect an ohmmeter between the thermocouple hot lead and ground. Resistance should be within 0.25. 0.50M.
Throttle body heating
Disconnect the electrical connector from the heater.
Connect a test light between the positive battery terminal and the heater. If the lamp does not light, replace the heater. When assembling the heater, be careful, incorrect assembly will lead to a short circuit.

Petrol Lawn Mower Care.
Petrol Lawn Mower Care.
A few simple steps to take care of your lawn mower will extend its life for many years.
Regular annual maintenance of your lawnmower will keep your gasoline engine running and running smoothly. Plus, regular maintenance will prolong the life of your car. You should also pay attention to extraneous sounds, uneven operation or decreasing engine power. If any interference occurs, stop operation immediately and rectify the problem as soon as possible, or seek professional advice..
In order to keep the mower in good condition, only a few simple manipulations need to be done on easily accessible engine parts..
Replacement of gasoline. Engine problems arise due to the fact that gasoline remains in the tank for the whole winter. Over time, it becomes runny and clogs the carburetor. To avoid clogging of the carburetor, after the last autumn mowing of grass, gasoline and oil from the tanks must be drained. Throughout the season, you should always use only fresh gasoline and do not pour a lot of fuel into the car..
Oil change. Every gasoline powered lawnmower needs good oil. It is required to change the oil in a new mower after 5 hours of operation, later after every fifty hours of operation of the mower. If you mow the grass once a week, then I recommend changing the oil twice a season..
Sharpening knives. Sharp knives will help prevent rapid engine wear. If the lawnmower stops cutting the grass evenly, then it’s time to sharpen the blade block. It is best to unscrew the block and give it to a specialist to sharpen it. Whoever sharpens knives himself with a file must ensure that the knives are equally well sharpened and balanced. The result of uneven sharpening is an imbalance that occurs, which leads to vibration of the device during cutting and significant damage..
Removing dirt. Regularly clean the painted surfaces of the machine and the underside of the mower’s undercarriage from grass and soil. Always check the air filter and if it is clogged, replace it with a new one.
If the mower has a two-stroke engine, it needs a mixture of gasoline and oil. Do not use pure gasoline as this will cause irreparable engine damage. Once a year, the wheel bearings must be lubricated with grease. To do this, the wheels must be removed and filled with grease in the bearing bores. Whenever you turn the mower on its side for maintenance work, try to put it with the exhaust pipe facing up. This prevents the oil from entering the carburetor, where it contributes to the release of fuming smoke during combustion..
List of maintenance work for the lawn mower:
– sharpening a block with knives – put the mower on its side, unscrew the knives, take them to the workshop, where they will be sharpened and balanced.
– oil change – warm up the engine so that the oil becomes liquid. Change the oil twice a season. Check the amount of oil regularly.
– replacement of the air filter – the filter must be unscrewed and cleaned. If after this it remains dirty, it must be replaced..
– cleaning – regularly clean and dry all surfaces of the mower. Remove grass and soil from the underside until they have hardened.
Replacing the spark plugs: – pull out the spark plug plug and unscrew the spark plugs using a special spark plug wrench. Screw new spark plugs into the car and tighten them tightly with a special spark plug wrench. Clamp the spark plug plugs firmly. Now check if the lawn mower engine starts.
First aid in case of breakdown:
– the engine will not start – check the presence of gasoline, make sure that the ignition wire is in contact with the spark plug plug, wet or oily spark plugs need to be cleaned or replaced.
– reduced engine power – unmount clogged air filters and shake them out to remove dirt, or replace with new ones, soot spark plugs need to be replaced or cleaned.
– the carburetor is filled – put the control lever to the “stop” position, pull the starter choke at least six times, wait five minutes, then put the lever to the “on” position. and start over.
– the mower vibrates during operation – the block with knives is loose, damaged or unbalanced, the block with knives should be screwed on or removed and given to balance (sharpen), if necessary, replace with a new one.
– grass gathers on the knives – wet grass can collect on the underside of the mower and prevent the knives from turning, turn the mower over and remove the grass with a screwdriver.
– fumes from the exhaust pipe – fuming exhaust fumes may mean that there are problems with the carburetor, valve or filter, the maintenance and repair of the lawn mower should be entrusted to a specialist.
– the engine runs unevenly – the spark plug or spark plug plug may be damaged, the wire must be secured, the spark plugs must be cleaned with emery to improve contact.
Fill the tanks with fresh gasoline and oil in the spring. If gasoline and oil have been in the mower all winter, have a specialist inspect the mower if possible. Check air filters. Mount a new or sharpened knife block. Regularly check the air filter for clogging during the summer lawn mowing season. Before each mow, check the mower for oil. Keep the underside of the mower clean. In the fall, at the end of the season, drain the oil and gasoline. To do this, lay the mower on its side. Which one depends on the design of the lawn mower.
To extend the life of the lawn mower, we do preventive maintenance, as it reduces the likelihood of serious damage. Good luck to you. and you can find the necessary lawn mower in our ONLINE STORE

How to clean a carburetor on a lawn mower
The section is devoted to motorized equipment for gardening, parks and earthworks. Here you will find information about the brands under which lawn mowers and tillers, chainsaws and cultivators are sold, everything that makes the work of summer residents, gardeners and communal workers easier. The equipment is subdivided into gasoline and electric (powered by accumulators and batteries as well). We have long been accustomed to tillers and cultivators; almost every second owner of a country house uses a chainsaw. In the section “Gardening equipment” you will find information about many other devices that will make your work pleasant and easy, and your site – an object to follow..
Trimmers – petrol or electric lawn mowers are wheel and hand-held. The mower is one of the trimmer options, adapted only for a certain type of grass. The shredder converts trash and wood waste into a homogeneous mass for compost and mulching. A garden vacuum cleaner is useful both for cleaning areas covered with vegetation, and for cleaning paved areas and paths. Any summer resident knows about the purpose of a sprayer and an electric hoe, but many only guess what a verticutter and a scarifier are. The verticutter removes the dense top layer that forms on the soil in early spring and late autumn. Scarifier (another name – aerator), in addition to cleaning the packed layer, makes grooves in the soil. Information about where, how and under what brand all this is produced is also in this section..

DIY lawn mower repair
A lawn mower is a very popular technique among owners of suburban areas. The larger the plot, the more often gasoline lawn mowers are used on the farm. This is not surprising, because gasoline cars are more powerful, more efficient, they can be used to process a much larger lawn in less time. In addition, the gasoline tool is not tied to the power source by an electric cord, which makes it much more maneuverable..
However, any gasoline equipment sooner or later begins to require repair, no matter how reliable and expensive it is. In the case of lawn mowers, malfunctions can begin after three to four seasons of active operation, and most often they appear after the equipment has been hibernated in unheated rooms. These problems manifest as follows: the mower may stop starting, the engine may intermittently run, or stall soon after starting. Often mower owners complain that after several years of use, the engine does not start working at full capacity, and the efficiency and productivity of the equipment decreases. All these problems in 90% of cases can be quickly corrected by yourself, and in this article we will consider the main causes of the listed problems..
It should be noted right away that the main reason for improper engine operation is the clogging of the engine carburetor with combustion products due to the long operation of the lawn mower or poor fuel quality. It is quite possible to cope with cleaning the carburetor on your own, but first you need to study the materiel. The volume of this article, unfortunately, will not allow us to consider the cleaning procedure in detail, but, however, the network has detailed step-by-step instructions for cleaning the carburetor, we recommend that you study it at the link: “Do-it-yourself lawn mower repair.” By cleaning the mower carburetor following the instructions mentioned above, normal engine operation will most likely be restored. If this does not help, you need to check some other possible causes of the problems..
Uneven operation of the mower engine can be caused by poor fuel quality. This is especially true if the gasoline has overwintered in a tank in a cold room. It is recommended not to use equipment filled with such fuel, it is better to drain it and fill the tank with fresh gasoline. In addition, a drop in engine power can clog the air filter. In this case, you need to replace the old filter or at least clean it with a vacuum cleaner. If the mower won’t start and show no signs of life, it’s probably a candle. You need to unscrew the spark plug and check if it gives a spark of proper quality. A normal spark should be clearly visible even on a sunny day..
Having dealt with the reasons mentioned in this article, you will surely restore the normal operation of your lawn mower, which is quite capable of serving you for more than one season. In addition, you will gain the skill of self-repairing gasoline equipment and save on garden equipment services..
The throttle assembly or remote control is the most useful device for the injector. Thanks to it, the additional air flow is regulated. For example, if you set the throttle opening to half, you can achieve a mode where air is supplied to the system during a slight engine start. To adjust the degree of open / close, the throttle actuator is adjusted.
In fact, on injection systems, the remote control performs the function of a dispenser. It is this assembly that is needed to prepare fuel assemblies in the required proportions. The remote control mixes a certain amount of air with gasoline.
The unit is located behind the air filter and is a damper or valve that regulates the amount of air entering the engine. Correct setting of the remote control will help to correctly adjust the ignition system of the injection internal combustion engine.
The degree of flap openness is a parameter directly related to the vehicle’s BC. It is the head unit, the brain of the injector, that decides whether to increase the fuel supply or not, based on the readings of the TPS (sensor installed in the remote control).
You should be aware that the greater the degree of opening of the damper, the more air enters the manifold, and the engine speed, accordingly, increases. And vice versa – the smaller the angle, the lower the RPM.
We will carry out the adjustment process on our own, that’s for sure. However, if you are the owner of a top-end car, the starting system of which has failed for any reason, it is better to contact a service center..
On the contrary, if this is a used Renault or our, domestic Gazelle car, there is no need to think about it. You need to take the adjustment procedure yourself.
In order to correctly set the ignition on the injection system, you will need a laptop with diagnostic software, a set of keys and screwdrivers, a measuring tester.
As you know, the injector is controlled by electronics. She, in turn, will obey the BC installed on the machine. In order to carry out the procedure with a high quality, you first need to test the connection of all electronic elements.
- Turn on the mass and ignition.
- The electric fuel pump is automatically switched on.
If it does not pump fuel, you need to immediately diagnose the operation of the relay that controls and controls the pump..
- Not having found a malfunction in the operation of the engine itself, you need to proceed to checking the throttle assembly. Pay special attention to the degree of throttle openness.
- Check the condition of the sensors.
All final parameters must be compared with those set by the manufacturer. For example, the on-board network must have a current with a value of 12 volts, and the degree of openness of the damper must be 90 percent minimum. If this is not the case, the throttle actuator is adjusted..
It is possible that the valves will also need to be adjusted in order to accurately trigger the valve timing. The procedure is carried out according to plan, every 20,000 km.
Valve adjustment can be carried out ahead of schedule if the characteristic clatter of the motor is heard.
Valve adjustment is always carried out using probes and other obligatory tools and fixtures. It is better to entrust this procedure to specialists in a car service..
How to adjust the ignition on the injector yourself
It has been a long time since the world’s first variable injection car appeared in the automotive industry. Today, the production of these models has grown significantly and supplanted the archaic carburetor models. Despite the obvious technical advantage of the injector, there are problems on these cars, and you sometimes need to know how to adjust the ignition on the injector.
Despite the fact that any injection power unit is entirely controlled by the ECU and does not require adjustment according to the assurances of the manufacturers, the urgency of labeling may appear periodically. Here, for example, if the belt of the GRS mechanism breaks or after repairing the cylinder head.
Placing marks on the injector is a process that will allow you to adjust not only the UOZ, but also to coordinate the operation of the injection system and the GDS mechanism as a whole. Thus, by correctly setting the labels, you can achieve full adjustment of the uninterrupted operation of all systems..
Here’s how the procedure is carried out on the native Gazelle:
- the wheel on the right is removed to provide free access to the gas distribution station drive mechanism;
- the plastic belt protector is removed;
- a shoe is installed under the wheel at the back;
- the car is lifted on a jack;
- the wheel is completely removable;
- part of the fasteners of the mudguard of the power unit is unscrewed, it is pulled to the side;
- thus, free access to the crankshaft pulley is opened.
- before placing marks, you need to resolve the issue of replacing the timing belt if it is badly worn out;
- the generator wheel is removed in order to more accurately set and check the exposure of the crank shaft;
- the roller tightening the timing belt is weakened;
- now you should check the position of the camshaft sprocket (the risk should correspond to the mark stamped on the timing drive);
- then you should check the lower mark on the crank shaft (it should match the mark indicated at the top of the cylinder head).
- you need to make sure that the marks on the flywheel and crankcase are not lost;
- then tighten the timing belt;
- turn the crank shaft several times and install the generator pulley;
- tension the alternator belt.
Now you can start the car engine, and after warming up, check the marks on the camshaft and flywheel again. If everything is normal, then the ignition on the injector is adjusted..

The device of the ignition system GAZ-53
In order to repair and adjust the SZ on the GAZ-53, you need to know how it works.
These trucks are equipped with a contactless SZ, which consists of the following components:
- power source – battery;
- additional relay;
- current indicator;
- resistor element;
- ignition switch (switch).
Knowing the device of the SZ, the connection diagram of the ZZ and its other components, as well as the functions that each element performs, it is possible to determine the malfunctions by signs and eliminate their cause. All components of the SZ can be divided into groups according to the tasks performed.
For the normal operation of the internal combustion engine, the following conditions must be met:
- powerful spark;
- the correspondence between the formation of a spark and the operation of the power unit;
- no gaps in spark formation.
The entire electronic ignition system consists of two circuits: primary and secondary.
The primary includes the following elements:
- Battery with large cross-section multicore cables;
- a switch that supplies power to the circuit;
- primary winding;
- a distributor breaker located in the distributor;
- a switching device that ensures stability of work;
- resistance required for successful engine start and short circuit unloading, excluding its overheating.
The secondary circuit includes:
- wires for supplying high-voltage current;
When the primary circuit is powered up, a magnetic field is generated in the breaker. The rotations of the distributor interrupt the current at this point, which leads to the disappearance of the magnetic field. At this moment, a signal appears on the secondary winding, which goes to the cylinders.
Successful sparking is ensured by stable operation of the motor and the appearance of sufficient voltage on the electrodes. The spark power is affected by the size of the gaps between the electrodes and the magnitude of the incoming voltage..
With a weak spark or its absence, fuel consumption increases, engine power decreases.
Ignition setting instructions
The reason for the engine overheating and a drop in its power may be late ignition. This can be manifested by pops in the intake manifold. Therefore, you need to know how to install the ignition correctly (video by Nail Poroshin).
Installation is performed by tags as follows:
- First, you need to set the piston on the first cylinder to TDC and align the mark of the installation indicator with the mark on the crankshaft pulley.
- Next, the crankshaft must be turned counterclockwise until the risks 9 on the indicator coincide with the mark on its pulley.
- Then you need to loosen the bolt of the upper corrector plate, thanks to which it is attached to the breaker.
- Next, you need to connect one control wire to the car body (ground) and the second to the breaker terminal. After turning on the ignition, the breaker should be slowly turned until the control lights up. This indicates that the contacts began to open..
- Now you need to tighten the breaker mounting bolt and install the cover and rotor. In the area opposite to that on which the rotor plate was installed, you need to connect the high-voltage wire to the spark plug on the 1st cylinder. The remaining wires are connected to the plugs of the cylinders according to the order in which they operate: 1-5-4-2-6-3-7-8.
It is necessary to set the ignition timing of the GAZ-53 precisely, since with deviations, the engine power decreases and the fuel consumption increases. In addition, it is possible to burn out valves, pistons, breakdowns in the cylinder head gasket and other problems associated with detonation..
Therefore, the final adjustment is carried out with the engine running, which heats up to a coolant temperature in the range of 80 – 90 degrees. With the engine running at idle speed, loosen the distributor fasteners with a “10” spanner so that it can be turned. Turning the distributor slightly counterclockwise, tighten the mounting bolt.
Clicking on the gas is how the powertrain works. If you hear “ringing fingers”, that is, detonation occurs, turn the distributor clockwise in the opposite direction. Through trial and error, we set the desired lead angle.
The check is done on a moving vehicle. With stable operation of the power unit, adjustment is no longer necessary.
Sometimes the distributor is pushed to the extreme position, but there was not enough adjustment. In this case, you need to check the position of the distributor drive relative to the engine.
A check is carried out on an inoperative motor:
- First, marks are placed on the front crankshaft pulley. They must match on the 1st and 6th cylinders. In order not to make a mistake, it is better to remove the valve cover from the first 4 cylinders and check the valves. With the correct position of the valve marks in the 1st cylinder will be free.
- Having removed the distributor, we inspect how the drive is installed. If it is located parallel to the motor, then its replacement or repair is necessary, adjustment, in this case, will not help.
- If the position of the actuator is incorrect, you need to unscrew the fastening nut and remove the part.
- After the drive is fully installed in its place, you need to check that the groove for the distributor runs parallel to the internal combustion engine (in the direction of the car’s movement), and a small section of the bushing on the distributor looks at the 4th and 8th cylinders (towards the driver) … Empirically, you need to achieve the correct position of the distributor drive.
What is the ignition order on a GAZ-53 truck: do-it-yourself installation and adjustment of SZ
The ignition system plays an important role in the internal combustion engine. The timeliness and power of spark formation and high-quality combustion of the fuel-combustible mixture depend on the uninterrupted operation of the SZ. How to set up the correct ignition order for the GAZ-53, how the system itself is arranged, what are its main malfunctions – it is said in this article.
Possible SZ malfunctions: signs and causes
Malfunctions in the SZ affect the power of the power unit, it decreases, and economical consumption of fuel.
The following reasons for the unstable operation of the SZ on the GAZ-53 can be named:
- Overheating or failure of the switch. When the switch overheats, the spark disappears and the engine does not start. It becomes possible to start the engine only after it has cooled down and a spark appears. The coil is also prone to overheating.
- Breakdown in high-voltage wires. This happens if the wire is not held tightly enough in the distributor cover: the motor will run unstable, intermittently. Breakdown of wires is noticeable in the dark – blue sparks slip through.
- The cover on the breaker-distributor is burnt out. The fault can be detected by visual inspection. Burning is possible in the place where the corner with the spring is installed. The lid must be free from defects, must not have potholes, cracks.
- The contacts of the distributor slider may burn.
- Breakdown of candles.
If the diaphragm makes gaps on the vacuum regulator of the distributor, then a drop in motor power is observed. At the same time, if you accelerate sharply, then the power unit will be swamped and may overheat. The distributor rarely fails, most often the reason for its breakdown is wear due to the exhausted resource.
The ignition should be adjusted until only slight knocking appears with a significant load on the engine power unit. If early ignition is set, this threatens a breakdown of the cylinder head gasket and burnout of valves and pistons. If the spark jumps later, the fuel consumption increases, and the engine may overheat. Precise installation is done with a stroboscope.
Setting and adjusting the gas column
Adjusting the gas column: an algorithm of basic actions and important nuances
Repair of gas equipment is associated with the need to comply with special safety rules. But the correct adjustment of the operation of a household heating column can well be done by an ordinary user on his own. If you do all the actions correctly, then the optimal operating mode of the equipment will be created, in which energy resources are used with maximum efficiency..
How to configure the speaker with your own hands
Such heating devices are available in a wide range. But the basic principles of their work in most cases are not very different. Let’s take a closer look at how to adjust the standard gas water heater. An electric spark is used here to ignite the mixture. On the front panel of the body there are two knobs and scales with graduations, which are used to dispense the supply of water and gas, respectively.
Failure of settings can occur for various reasons, including after insufficiently careful handling of the equipment by users. In any case, you should start by setting the nominal water pressure. This value is indicated in the technical data sheet for the product. If paper documentation is lost, then the relevant information can be found on the Internet at the manufacturer’s website
Let’s say the nominal flow rate is 6 liters per minute. In order to correctly set the required value, the tap (hot line) is first opened only at one of the points of the water supply system. Next, the regulator is installed on the column body in the desired position, limiting the pressure. After – the hot water tap closes.
The preparation of the gas path is in progress. The regulator on the column is set to the minimum allowable position. The device is connected to a standard 220 V network, or batteries are installed. Only after completing all the previous steps does the gas mains valve open.
Now, if you open any hot water tap in the system, the column should turn on automatically, heating will start. Further adjustment will require temperature measuring instruments. The handle on the panel, increasing / decreasing the gas supply must be set in such a position that the liquid temperature at the outlet is higher than at the inlet by 25 ° C.
What features of the equipment should be taken into account in order not to make mistakes
After the exact execution of the algorithm described above, subsequent changes in the leaving water temperature should be made only with the handle that regulates its pressure. If the flow rate is reduced, then the liquid will move more slowly inside the heat exchanger, which will provide higher heating. The maximum permissible temperature is stated in the operating instructions and should not be exceeded. This will extend the life of the equipment..
When performing adjustment operations and in the process of subsequent operation, one should remember about the inertia of this type of equipment. The heating of the liquid in the gas columns does not occur instantly, therefore it is necessary to ensure its drainage for a certain time to raise the temperature to the required level. If the equipment is turned on with a short break, then in this case it is necessary to take into account the presence of hot water in the system. Do not use it too quickly to avoid scalding..
The same feature is taken into account when setting up. The process of obtaining the aforementioned temperature difference (at the inlet and outlet of the column) can be somewhat delayed. However, there is no need to rush. It is necessary to precisely select such a position of the gas regulator in which the set value does not change for several minutes..
The scheme of actions given in this article will be applicable only if the equipment is fully operational. In the absence of ignition of the gas-air mixture, insufficient heating efficiency, it is necessary to eliminate the malfunctions that have arisen before making precise adjustment. Some restorative operations can also be performed independently. The correct operation of the equipment and regular preventive measures will help prevent the occurrence of breakdowns..
