The lawn mower does not start the causes of the malfunction. More complex reasons for the refusal of the lawn mower

The lawn mower does not start or stalls?

Many owners of gasoline lawn mowers sooner or later face technical problems of this technique. Most often, problems arise after three to four seasons of active operation of the lawn mower or after the equipment spends the winter in an unexplored garage. These problems are manifested as follows:

  • The lawn mower will not start
  • The lawn mower starts up, but soon stalls
  • The engine of the lawn mower is working with interruptions
  • The engine of the lawn mower does not work at full power

It doesn’t matter what engine is on your mower: dear Japanese Kawasaki or a simple Chinese Lifan, during the years of operation these problems are more likely to appear in all lawn mowers. However, do not be upset and rush to take your mower to the service center. In the vast majority of cases, the lawn mower can be easily repaired with your own hands. In this material, we will tell you step by step how to do it!

We identify the cause of the malfunction

To repair the lawn mower yourself, it is best to be guided by the principle of “from simple to complex”. First, check if there is enough gasoline in the tank. If the mower stopped starting after wintering, it is worth draining the old fuel and replace it with a new. Sometimes low.quality gasoline comes across, which can give a precipitate or even delay in the winter, and some gas mowers are very sensitive to fuel quality.

If there is confidence as gasoline, but the lawn mower does not show signs of life, the next thing you need to do is check the spark. To do this, remove the wire with a cap from the candle and twist it with a special candle key, which should go with the lawn mower. Then throw the cap on the candle, attach its threaded part to the metal part of the engine and ask someone to pull the starter. At this moment, a bright blue spark should appear, which is clearly noticeable even during the day. Keep in mind that you need to lean the candle against the clean metal surface of the engine, which is not covered with paint and which can be current.

The gasoline trimmer for grass stalls at idle

Often, when reducing the speed, the motor motorcycles stalls and does not support idle speed when re.starting. The main reasons for the occurrence of such a breakdown include pollution or the dumping of the carburetor, as well as clogging of the air filter.

Gasoline trimmer for grass stalls at idle

In case of violation of the optimal settings of the carburetor, it is necessary to clean it and repeated adjustment. You can cope with clogging the air filter of a trimmer for grass by placing it for several hours in a solution with a conventional domestic detergent. If independent cleaning has not helped to cope with the blockage, it is better to purchase a new filter element in accordance with the operating manual.

After the measures, the user will not encounter a situation for a long time when a trimmer for grass stalls in idle and functions only when gas supplies.

The structure of the lawn mower

Before repairing the device, it is necessary to understand what it consists of. There are many models of garden technology of different brands: self.propelled, self.propelled. They are all the same. Construction components:

  • Platform on wheels;
  • Gasoline engine (starter, carburetor, ignition and fuel supply system, air damper, filter, piston system, fuel tank.);
  • A pen;
  • Water.jet nozzles;
  • Cutting elements (knives);
  • Grass collector (container);
  • A section of cutting fresh grass;
  • Buttons, control levers;
  • Corps (aluminum, steel, plastic).

Key causes of breakdowns

Lawn mowers and trimmers for grass often stop starting after long.term storage. To determine the cause of the malfunction, you should make multi.stage diagnostics using special means. In most cases, trimmers for grass are breaking due to problems with gas tank and filters.

Much depends on the resource of the tool. The older the unit, the more difficult it may be breakdown. Each part of the trimmer for the grass has its own recommended operational period. When it comes to an end, the spare parts of the lawn mower are recommended to be replaced with new.

Fuel tank problems

Before starting the lawn mower, you should check the quality and technical characteristics of the fuel and oil used.

To determine the right amount of oil and fuel mixture, you must familiarize yourself with the operation manual. Fuel into the tank is poured exactly at a time so that it can be fully consumed during the work.

Fuel in the lawn mower should be poured as accurately as possible. To minimize the likelihood of falling beyond the borders of a trimmer for grass, you can use a standard funnel

If you leave fuel for a long time in the tank, after some time it will lose its key characteristics. Such gasoline can seriously harm the engine and lead to its breakdowns. For this reason, you should not pour fuel in large quantities for the future.

Often, lawnmands cease to start precisely because of the presence of old fuel in them. In this case, you need to pour the old mixture, clean the tank and pour new gasoline into it.

The recommended characteristics of the fuel mixture, which should be used on a benzoca, (in t.h. The exact ratio of gasoline with butter) can be found in the instructions for operation

In this case, the fuel poured into the tank must have appropriate physicochemical characteristics. It is not recommended to use low.quality gasoline mixtures of unknown origin.

Most of the manufacturers of trimmers, for example, STIHL and Husqvarna brands, recommend pouring gasoline brand into the tank at least AI-95. It can be bought at a proven gas station.

It will depend on the use of highly octane and high.quality fuel how much a trimmer can last for grass.

Construction of candles and candle canal

In the case of a trimmer for the grass, you should make sure that the candle canal does not throw a combustible mixture. If you do not transfer the air damper in a timely manner to an open position, the candle will be filled with gas when the engine is turned on.

To make sure that problems with the launch of the lawn mower are associated with candles and a candle canal, the following actions need to be performed:

  • unscrew the spark plug, clean it and dry it, Only dry candles can be placed in internal combustion cylinders;
  • Drain unused fuel from the hole in which the candle was located;
  • Remove the soot on the candle. you can conventional manicure supplies (scissors or files);
  • collect the block again and restart the system.

In most cases, these manipulations will make it possible to start the engine.

If, after replacing the candles, the trimmer for the grass does not work, you need to check the presence of a spark. If it is not, then you need to check the cable (call the tester) connecting the coil and candle. If problems with the wire are detected, you need to stretch a new high.voltage cable.

Fuel supply malfunctions

If a braid for grass leaves a wet trace and there is no traction, this indicates problems with the fuel supply. Its condition can be checked visually. cracks and holes can form on the fuel line.

Usually a leak and any mechanical defects are quite noticeable, and therefore are easily determined during the usual inspection.

It is especially necessary to check the fuel chip on the Chinese benzocosa, since it can be strongly deformed (twisted or torn)

Regardless of the nature of the malfunction, the defective wire should be replaced with a new. When selecting such components, the original spare parts should be selected.

Why does a trimmer for grass stall quickly?

If the lawn mower stalls after seasonal storage, it is necessary to conduct maintenance. It consists in removing the fuel system, in t.h. fuel and air filters, analyzing the carburetor, cleaning parts, blowing filters and replacing fuel.

During the service, the owner needs to make sure that all the details of the trimmer for the grass are not broken and can perform their functions.

When a trimmer for grass starts and stalls quickly, you should check the integrity and cleanliness of the air access valve into the fuel tank. If the valve is very clogged, then a vacuum will create a vacuum in the tank, which is why less fuel will get into the carburetor, and the lawn mower will start, but soon after that it will stall. To resolve the situation, you need to clean the valve, as well as start a device with a not completely twisted lid of the fuel tank.

In addition, a trimmer for grass can suddenly stall due to an insufficiently adjusted carburetor. Indirectly, the problems with the carburetor indicate vibrations when working the motor. Such signs indicate several malfunctions at once: poor control of the idle speed, a change in the composition of the fuel mixture and the weakening of the adjusting bolts of the carburetor under the influence of vibration and other forces.

Weakening of adjusting bolts on the gas mowing carburetor can easily be determined during a visual inspection without the use of special equipment

Repair and adjustment of the carburetor should be carried out with clean filters (fuel and air). All the nuances of the repair are present in the instructions for the trimmer. This operating instruction is always included in the device.

Without problems, they coped with the detection and elimination of a breakdown breakdown? But you have problems with a washing room, refrigerator or air conditioning? We recommend that he get acquainted with the most common breakdowns of this technique, examined in detail in our other articles:

Problematic issues with a carburetor and fuel system

Before starting repairing the engine of the lawn mower, it is worth checking if the pistons lay down. To do this, it is necessary to dismantle the motor. We also remove the carburetor from the structure and conduct visual control for the availability of possible defects. Usually in disassembly you will need a special Torex screwdriver with nozzles.

We inspect the gaskets for the identification of ruptures or burning. If one is found, then you need to ensure the tightness of the structure, replacing them with new. The air damper may contain a layer of soot, which reduces the quality of the fuel mixture. You need to get rid of the cleaning of the carburetor by raining the node in the solvent or kerosene.

Sloving during operation or the absence of a set of them to enter the operating mode together with the overheating of the power unit are the causes of such events:

  • Idle adjustment violation. You can unscrew the nozzles yourself with a screwdriver into the right position. It will be possible to do this even by ear, so that the motor works smoothly. No need to shoot knives, but they should not rotate.
  • There is an air filter pollution. It is enough to extract it out and clean, rinse. We dry in natural conditions in the wind, without putting a stove or fireplace.

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

To clean the fuel chamber, first wipe it WD-40, then soak mines at 15-20, wiped again. So you need to repeat 3-4 times to completely clean the camera and channels

The clog of exhaust leads to a narrowing of the output flow of the exhaust pipe. Resins appear on the inner surface due to the incorrect ratio in the composition of the fuel mixture and oil. We twist the crankshaft so that the piston comes out to the maximum up and clean its surface with a wooden stick.

In more serious cases, it is recommended to contact the warranty service. Otherwise, unprofessionalism will bring more breakdowns. over, with independent search for a malfunction and repair during the warranty period, the guarantee ceases to.

Most likely, it will not force its owner to face the problem of the causeless, at first glance, refusal of the motor, but such models have their shortcomings. There are a number of reasons why a liquid fuel machine can begin to “act up” even if it is produced by a reliable company.

Sometimes it happens that even the best unit designed to mow grass does not turn on. There are a number of reasons why the gas mowl does not start gasoline. Their list and methods of elimination are offered to your attention.

Lack of spark in the spark plug. It is necessary to check in what position the grounding coupling is located. Before the work of it (a switch with the inscription “ON/OFF”) must be installed in the “ON” position. Otherwise, the spark will not form in the spark plug and the engine will not start.

Lack of fuel in the tank of the lawn mower or the formation of condensate in it. Condensate can be formed when storing a refitted lawn mower. It is necessary to drain old gasoline and pour fresh. It should be noted that violation of the conditions of storage of equipment may entail the refusal of even very reliable models of Stiga Dino 47 b. Makita PLM 4110. LawnPro EUL 534TR-MG.

The position of the fuel crane regulator. With closed fuel tap, gasoline will not enter the engine.

The cold engine does not start. It may be necessary to block the damper. Without it, the motor does not receive enough fuel.

The warmed engine does not start. Perhaps the air damper is blocked. When trying to launch an excessive amount of fuel into the engine cylinder and pour a candle. We have to wait a while, while gasoline from the candle evaporates, and make a new attempt.

Insufficient oil level. Why is the gasoline law mower not starting if it is installed in it a oil level sensor? It grounds the ignition circuit in the gas mowing motor and, with its insufficient level, or when the lawn mower is in the inclined position, blocks the launch. Should be added oil or put the law mushroom horizontally.

Perhaps the spark plug does not work. It is required to turn out the candle and clean it.

Knives were removed from the lawn mower. The machine with the knives will not start, because their blades work as part of a rotating array.

The motor starts up, but stalls. Some mechanisms can jam. crankshaft or piston. You should scroll on your own several times and try to start it again.

In other cases, why the gasoline law mower is not started, in particular: the engine works unevenly, it does not have enough power, it overheats or greatly vibrates when working, it is best to contact the service center.

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen In the area of ​​the engine.

Damage of gasoline trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:

  • engine breakdown;
  • problems with the carburetor;
  • problems with the supply of fuel;
  • muffler malfunction;
  • gearal breakdown;
  • The starter broke;
  • Air filter problems;
  • Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

It should be noted that the elimination of some of them is best entrusted to the specialist.

What to do if the lawn mower is not started?

Lawn mowers based on internal combustion engines are the most convenient and popular in everyday life. Unlike electrical units, they are autonomous and do not limit the area of ​​operation the length of the power cord.

However, like any complex mechanical devices, gasoline lawn mowers periodically fail or simply fail to fail. Below we will consider the most common breakdowns of lawn mowers operating from four.stroke internal combustion engines.

Common causes of breakdowns

First of all, it is worthwhile to verify the simplest things: the presence and quality of fuel, the correct order of action.

Use only those fuels and lubricants that the manufacturer recommends. Gasoline with too high octane number is sometimes no less harmful than the 80th. The instruction has not been preserved? Universal can be called AI.95 with a car gas station with a good reputation.

Pour only suitable engine oil. In the vast majority of gasoline trimmers, the engine is 2-stroke, so ordinary car oil cannot be used. For a 4-stroke engine, the oil is poured separately from the fuel. over, it is not worth pouring “working out”. used, used oil.

Remember, the repair of the piston group will cost 30. 70% of the cost of the new motorcycle. Savings on the quality of combustible materials is unlikely to cover these expenses

Exactly observe the proportions of mixing gasoline and engine oil, do not lie “by eye”. For most motos, a ratio of 1:25 is recommended, that is, 40 ml of oil per liter of gasoline.

Do not cook a lot of mixtures at once: ideally it needs to be developed in 1 day and store equipment with a dry tank. The maximum shelf life of the finished mixture is 2 weeks, so more than 2 liters at a time it makes sense to mix only to utilities who cut the city lawns.

If you have not used a scythe for a long time, and there is gasoline in it, it is better to pour it out. The mixture has already been divided into fractions and lost its properties, even the most thorough mixing will not save it.

After making sure that the gas tank is in order, try to get a braid. For this you need:

Top Reasons Hedge Trimmer Won’t Start — Hedge Trimmer Troubleshooting

  • Switch fuel into the carburetor with a grain button 5-6 times.
  • Close the air damper.
  • Turn on the ignition on the handle.
  • Pull the starter’s cord 1-7 times, until the launch.
  • In 5.10 seconds disconnect the start system.

After downtime, if you can’t start the engine in the usual order, try to open the throttle and press the gas trigger. Without releasing the trigger, pull the starter cord.

A fully working trimmer for grass is started 1-2 times, even if the cord is calmly pulled, and not pull it as much as possible

It is also recommended to start a motor with a clamped gas handle if it has not yet cooled after the previous working cycle.

If the engine has not started on 5-7 jerks, it is worth looking for a breakdown.

Option. a problem in the ignition system

The first thing that suspicious falls is. the candle does not give out a spark, and therefore the fuel mixture does not ignite. Most often the problem is in the candle itself.

For verification, unscrew the spark plug from the cylinder, having previously disconnected the wire from it.

The thin layer of brown soot indicates the normal operation of the engine, red or pink soil. an abundance of fuel additives, change the gas station. If the element is covered with black or white scale, the engine worked incorrectly.

Wet candle indicates overflow, excessive pumping of fuel with a primer. In this case, the candle needs to be dried, but not to get. Pour excess gasoline from the cylinder, turning the motorcycle.

When cleaning, pay the greatest attention to that part of the upper electrode that is aimed at central contact, but do not zeal too much

Contacts of the dried candle should be cleaned of soot with the help of a suprafil, sandpaper or ladies’ file. The gap between them should be 0.7. 1 mm. this is the thickness of the standard coin. If necessary, bent the upper electrode.

Before assembly, it is worth checking the performance of the candle. Connect it to the power (put on the cap), attach the body to the cylinder or any metal part of the engine, turn on the ignition, pull the starter. At the end, between the electrodes, with each jerk, a bright, powerful spark should slip through.

It is very important to observe safety precautions. There should not be a drop of gasoline on the neck of the candle opening and the body of the motorcycle!

How to fix a lawn mower that won’t start Ten Minute DIY Repair

If after drying, cleaning and setting a sparking gap, buy a new candle. It happens that the spark does not appear on the new candle. In this case, check the quality of the contacts, try to replace the armored vehicle. this is inexpensive and simply.

If there is no spark with a new wire, you need to buy a new ignition coil. It happens that the cable is not disconnected from the coil, they are sold only in the collection. It is somewhat more difficult to replace it on your own, because you need to accurately set a gap of 0.25. 0.4 mm to the stemstone flywheel.

The normal gap corresponds to the thickness of the plastic bottle (cut a piece of measurement from it) or 4-5 layers of painting tape

Install a coil with a spacer, try on. Twist the starter: it must touch the spacers, but completely turn. Remove paper tape or plastic and finally collect the knot.

It happens that when checking, the candle gives out a small but stable spark, but the launch does not occur. After you tighten the candle into the cylinder, in a closed space, a weak spark may disappear. In such a situation, it is also worth replacing the coil: the new one will give out a more powerful impulse.

Option. you need to replace the filters

If there is a spark, but the braid for the grass is not started, the problem is most likely in the fuel supply. The easiest way to check the air and fuel filter. with this and start.

Testing their condition is quite simple: remove the filter elements and try to start the motor. If it turned out, you need replacement or at least cleaning.

lawn, mower, does, start

The fuel filter can clog so much that its body will not be visible. Naturally, attempts to clean in this case are useless

Other tool malfunctions

If all the problems described above are checked and eliminated, and the trimmer for the grass still does not start, probably problems with the engine itself. It may reduce compression due to the destruction of crankshaft oil seals or damage to the piston group.

This more often happens with trimmers that are used very actively or for a long time: for example, in utilities. To diagnose, use a compressometer.

The oil seal protruding from the crankcase is subject to replacement. it has already hardened, has lost its elasticity and cannot fully fulfill its function

In most cases, such a repair should be entrusted to the workshop, if only because in almost all trimmers for access to the oil seals and the cylinder, you need to unscrew the nuts with a thread fixer. You can do this either with an electroger.controlle, or warming them well.

The seals are located on both sides of the crankshaft: under the starter and on the drive, and it is better to change them with a couple. Having reached the place of installation, evaluate the condition of the eye: they should sit tight, without backlash and not to bulge, not to be cracked. Oil Sunses around also indicate the need to replace the seals.

When reverse assembly, be sure to use thread fixers wherever they were. this is a security issue.

To easily pull out the seal, screw into it 2 self.tapping screws from the opposite sides. Pull the screws in turn with the help of pliers.

Restoration of the piston group requires a specialized tool. If you are not a car mechanic for a hundred, trust the restoration of a trimmer motor for the grass to a specialist.

When opening the cylinder, all surfaces are checked for chips, bullying, scratches. To determine if the piston rings are worn out, shake the connecting rod. The slightest backlash of the piston indicates the need to replace the rings.

Visual inspection

Before working with any faulty device, you need to conduct a visual inspection. one that does not require a complete disassembly of the device. Agree: it is much easier, for example, to check the battery of the phone, the screen of which sharply stopped working, attaching it to the power, instead of completely disassemble the display, check the train, etc. D. So:

  • First of all, we check whether the required amount of gasoline is available inside the motor. If the reason is this, then the rest of the actions do not need to be performed (and so similarly with each paragraph).
  • We look at the possibility of gasoline or oil. You need to do this in good lighting or just use a flashlight.
  • We look at whether the motor has external deformations.

Engine problems

Common reasons and ways to solve.

Frequent problem. air filter pollution. Take it off. If without it the motor starts to work better (this can be determined by sound), then the reason is found. If when the hand is closed with the hand, the engine reduces the speed, then this additionally confirms that the case is in the filter pollution. It is recommended to replace it with a new. You can also clean it with a vacuum cleaner or rinse thoroughly with a rag using a dishwasher or the same soap. The main thing is a thorough subsequent drying. After you need to very carefully grease the filter with oil and leave it for half an hour to absorb.

If the engine works, but reduces the moment, perhaps the blame for the ignition. The problems with this element are also evidenced by a large fuel consumption. You can check it using a special “gun”, which is sold in any automobile store. To do this, insert the candle into the hole. If after that there is no spark, then the element does not work. you just need to buy a new one and replace.

Check the sapun. This is a part of the engine that serves to maintain the same pressure in the gas tank. If it clogs, then, most likely, a vacuum will be created, which prevents the fuel further. To check, you need to dismantle it, and then close the hole with your palm in which there was a saopan. If there is no pressure, then the matter is in it. After cleaning the bacon yourself, mount it back. If the motor has not started to work, it may be in the rings. They should be checked using a compressometer. Before checking, warm the power unit: if there is not enough atmosphere, we change the ring.

Fairy tap breakdown can also indicate problems with the engine. Its deformation is very easy to see with an external examination of the part. If it is broken, replace it. To check, first of all, you need to disconnect the spark plugs wire and fix it away from the candle itself. Remove the casing, unscrewing the bolts. Install the filmmaker of the flywheel, remove it with the veneer. If deformation is detected, the spare part is replaced.

If the motor starts up, but immediately stalls, then this may indicate a damaged insulation of the ignition system. So, touching the metal of the case, the current passes further, there is a closure that extinguishes the spark.

The problem can also lie as fuel. First of all, you need to check if there is an excess of oil, then. gasoline itself. On the fuel in no case should be saved! You can check its quality in three ways:

  • By color. To do this, pour fuel into a small transparent jar. If at the same time the color of gasoline is pale yellow, then it is in perfect order-exactly the one that is needed is chosen. If the shade is different, it can talk about cheap impurities. They quickly spoil the engine, which means that it will have to be taken to the nearest service center.
  • Consists in the use of potassium permanganate. We also pour into a jar, dilute with potassium permanganate. If the fuel quickly repainted pink, this means that it has a large amount of water that should not be.
  • Drip a little gasoline on a sheet of paper. Wait a couple of minutes: if it has not completely evaporated, and the paper changed its color, impurities are present in the fuel.

If the lawn mower smokes strongly, this may also indicate gasoline prepared for two.stroke engines. The next time you just need to choose it wisely, and before that it is worth changing the spark plug.

If the shaft does not rotate, then the problem in the “oil starvation” is a lack of oil in the engine. In addition, insufficient oil is used. To repair the crankshaft, a complete dismantling of the pallet should be carried out. You need to replace the bearings. Additionally, it is recommended to clean the channels if there is dirt in them. She can also negatively affect the lack of oil to lubricate parts.

If the candle is wet, problems with the carburetor are possible. When wear out gaskets, they should be changed. You also need to rinse it by partial disassembly. First remove the air filter and cover. After we extract all the contaminated elements, completely wash them so that they look like new. After we collect everything back. Details must be soaked in cleaning liquid, which can be bought in the store. It is also permissible to replace it with clean gasoline or kerosene. If necessary, the carburetor can be blown.

The above recommendations in most cases help to cope with a trimmer malfunction. However, it should be noted that it will simply simply be given the device to the service center.

Repair of malfunctions of an electric mower

Long grass that has wound on them can be led to jamming knives. For repair, you need to turn off the device from the network and twist the cylinder in the opposite direction.

If the electrical device is silent, the drive belt breaks the resulting result of wear: it can be stretched or broken off. This means that you can not do without replacement, for which you need to remove the protective cover.

The new belt is first installed on a small gear of an electric device, then, put on a large pulley, and turning it on.

To replace the power cable of this electrical device, it is necessary to de.energize the device and unscrew the lid.

To disconnect the cord, insert the hexagonal key into the hole with the wires, freeing the clamp.

The new power cord is installed in the reverse order.

The reason may also be hidden in a faulty power switch, which is simply replaced by a new.

Repair of an unexpectedly stopped electric engine

If the motor worked, but suddenly stalled, you need to check the crankshaft and the piston. perhaps they were overwhelmed. This is due to the absence of oil in the crankcase. It is better to contact specialists with this breakdown, as in the case when the electric motor of the lawn mower requires repair.

For non.precise operations of the lawn mower, the owner must conduct its regular maintenance after the end of the working season, t.e. Before her premises for winter storage. This will cost cheaper than repair or buying a new electrical device.

Among the main measures that ensure the reliable operation of an electric mower is clean. The mowed grass accumulated under the neckline causes erosion of metal parts. The compressor or blunting will help to remove the remaining weeds.

The electric motor of the mowing is air cooling, therefore, it also requires a cleanliness that is a key to effective functioning. Suitable for cleaning the cooling ribs soft brush and compressed air.

Timely oil replacement specified in the use guide will become the key to prolonged work, as well as the periodic cleansing of the air filter.

In the presence of a certain experience, it is easy to repair the lawn mowers with your own hands. The video below will help in this.
