Why the trimmer for the grass does not start: the causes of the malfunction and ways to eliminate them

It’s time to cut the lawn, and the lawn mower does not work? It’s even scary to imagine how to maintain the lawn in perfect condition with a manual tool, especially when this was not done before. If a trimmer for grass does not start, the reasons can be very different, but you can eliminate most of them yourself.

This will not need either a special tool or highly specialized knowledge. A little courage and free time to read this material. and a trimmer for the grass will not need to be taken to the master.

In this article, we will tell you how to determine what exactly interferes with the launch, we will give instructions for the repair of each node and recommendations on how to avoid problems in the future. For clarity, photos and videos await you, where the most common breakdowns are clearly dismantled.

Common causes of breakdowns

First of all, it is worth making sure of 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:

• 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!

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.

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

Check the filter

Another common reason why there is no starting trimmer for grass

The presence of clogging in the filter area. To confirm the assumption, it is enough to dismantle the indicated block and try to launch the device without it. If the trimmer engine starts up, you will most likely have to replace the air filter or at least carefully clean the old. If there is strong contamination on the surface of the filter element, you must use a new grid. Do not leave a suction pipe completely without a filter. Indeed, a rush in this case can lead to the need to repair the entire piston group of the engine.

Complex reasons for the refusal of the lawn mower

If the step-by-step algorithm for searching for a malfunction has not given a result, and your braid for grass still does not start or stalls, it is worth examining the carburetor and the engine itself.

A clogged carburetor can become one of the reasons, unstable operation of the tool.

Three main problems can be distinguished here:

• Clogging of channels or nozzles. All this is cleaned with special flushing or blown by a powerful stream of compressed air from the compressor. Do not use needles and wire, so the passing sections can be damaged;
• Wear of the carburetor laying. Output. replacing the failed laying;
• Violation of tightness. To check this indicator, you can use the usual household tonometer, replacing the pressure gauge on it with the right. Follow the testimony: if they do not change, everything is fine, and since the pressure will begin to fall, then some part of the carburetor is faulty. Will have to find it and replace it with a new.

If everything is in order with the carburetor, then the gasoline trimmer for the grass may not be launched due to wear of the piston group. If chips, scratches or bully are found, on the piston or cylinder they should be replaced.

Piston rings are subject to mandatory verification. A small rally piston when swaying the connecting rod indicates that the time has come to change the rings. This procedure is best entrusted to the specialists of the service center.

Rules for the operation and storage of a lawn mower

In order for the lawn mower to start well and continue to provide it with good storage and operation conditions:

• During operation, carefully monitor the cooling system, carefully and in time, clean the channels in the case, as well as the ribs of the starter;
• If necessary, use solvents, kerosene and other detergents for cleaning;
• Do not clean the “hot” tool. let it cool;
• Stactly comply with the requirements of the instructions for the operating mode, otherwise you can overheat the engine;
• If you do not plan to use the lawn mower in the next month, the fuel mixture from it needs to be drained, t. to. Over time, it breaks up into heavy fractions, which will definitely clog the channels of the carburetor;
• After draining the fuel, let the trimmer work at idle until it stalls, this will help to completely remove the rest of the working mixture.

Before winter storage, take the following steps:

• completely disassemble the braid, rinse and clean all the details you can;
• Inspect the details for damage, if necessary, eliminate distortions, impulses, bent and any other malfunctions;
• Pour a sufficient amount of oil into the gearbox and clean the air filter;
• You can partially disassemble the motor, rinse, blow and smear all the moving parts;
• In order to lubricate the piston, you need to unscrew the candle, raise the piston with the outlet to the extreme dead point, pour a little oil into the candle hole and scroll the crankshaft a couple of times;
• If you store the lawn mower not in the house, wrap the engine with an oiled rag.

The second is a carburetor

It is not necessary to disassemble the node right away, especially if the engine stalls after starting or does not hold idle. First try to change fuel, maybe an excess of oil. You can inject the cleaner air filter, let the motor “laugh” a little at maximum speeds.

Next, go in order. the air filter, the fuel filter (it can be outside and in the tank), the fuel pump button, the integrity of the hoses. Gas tank plug. the ventilation valve can be clogged, the motor simply does not pump gasoline. Get everything. and will work!

Be sure to look at the connection of the carburetor with the intake manifold! Elsey there sucks air and there is no tightness. eliminate!

The dosing needle hangs. the problem is also in some models. It is enough to push it down, or remove and polish it with a velvet.

You can pull the hose from the carburetor, see if the fuel is coming to it when pumping. It is clear that you often need to remove plastic casing for verification, break your fingers on the latch, but still sooner or later you will have to climb there.

Where to start diagnostics motorcycles

If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main nodes and assemblies. The test algorithm is as follows:

These nodes are most often source of basic problems, which can be eliminated after a thorough inspection.

Check the fuel mixture

Before starting the engine of a gasoline braid for grass, check the presence, and the quality of the fuel mixture. Do not save, do not greedy and “do not smarter” in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil fuel mixture strictly according to the instructions. Calculate its number from real needs. Excess gasoline left after work loses its qualities over time.

We diagnose a candle and candle canal

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be the reason. Here, a regular candle key is suitable for repair (every motorist has probably has a spare candle.

• We twist the candle and wipe;
• We thoroughly dry it (you should not bake it);
• Excess fuel in the chamber we drain through the candle hole and dry it;
• We clean the old candle from the carbon on a sugar or a ladies’ file;
• We set a gap with a distance of 1 mm (you can check with any coin);
• We return everything to place and try to start a trimmer for the grass.

Dry the channel at least 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.

If the working candle is working, the nest, where it is located completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly moisturized. No matter what wonderful spark gives out a candle, there is simply nothing to light up in a dry chamber.

Basic rules for the operation of the lawn mower

The lawn mower needs high.quality and accurate operation. The estimated period of its service and the absence of any serious malfunctions depend on this.

• monitor the cooling system during operation;
• Timely clean the charter channels and the starter ribs, and special detergents or ordinary kerosene should be used for cleansing;
• cool the tool before subsequent cleaning.

In the case of draining the fuel, you need to give a benzos to work at idle speed until it is stalled. This will make it possible to remove all the remains of the working mixture, regardless of the power of the device.

How to prevent a breakdown during storage?

Lawn mowers are used in the warm season. For the winter they are cleaned in storage in the pantry, closet or garage.

Maintenance of the trimmer for grass should be produced several times a year (in t.h. after winter storage) to increase its possible service life

To prevent a tool breakdown, you need to properly prepare it for seasonal storage:

• Drain the fuel mixture. it must always be drained if you are not planned to use the device within a month, t.to. The fuel decays into various heavy fractions over time, which can score the channels of the carburetor;
• completely disassemble the lawn mower;
• Rinse, clean and dry all the details to which there is access;
• inspect all the elements of the trimmer for the grass for damage;
• eliminate all possible malfunctions, distortions and minor defects;
• pour a sufficient amount of oil into a gearbox;
• partially disassemble the engine;
• Rinse and grease all the necessary elements in t.h. piston;
• Clean the air filter.

If the lawn mower is stored outside the house and the residential area, it can be wrapped in an oiled fabric. This minimizes the risk of rust on the instrument and increase its life.

Thorough preparation and processing of a trimmer for grass will allow you to keep the device for several seasons without a question.

What needs to be done if a candle of a chainsaw was flooded?

Most often, this occurs in beginners when, at the first launch, “cotton” is passed on a closed air damper and continue to pull the starter handle, respectively, gasoline in the combustion chamber is obtained a lot, and not enough air does not allow gasoline to ignite.

• Unscrew the candle with a candle key and check its condition. If the candle is wet and there is a spark, then it was flooded. Open the air damper, turn on the switch button, squeeze the gas “until it stops” and start. Excess gasoline should get out of the exhaust saw and the saw will start.
• Unscrew the candle with a candle key and check its condition. If the candle is wet and there is a spark, then it was flooded. Turn the chainsaw with the opening of the candle down and take the starter ten times, while excess fuel will flow out of the engine cylinder. Then wipe the dry dry (replace) a candle, or replace with a new one and repeat the engine factory attempt to follow the operating instructions. If the candle is absolutely dry, then this means that fuel does not enter the engine. And since it is in the tank, it is likely to the problem in the carburetor. You can get a little mixture into the syringe, injected into the cylinder, tighten the candle and try to start the engine. But if the engine started up and immediately stalled, therefore the problem remains and you need to contact the service center.

Remember, careful compliance with the rules will allow you to forget that the lawn mower is bad for several seasons.

How to clean a carburetor?

Start by checking for open fire nearby. Do not repair the room. It threatens gas leakage.

Unscrew the screws with a flat screwdriver to remove the plastic cover of the air filter from the engine. Check the clogged filter, remove it using a vacuum cleaner or replace it with new (if the condition is unsatisfactory).

It is also necessary to remove the inner cover of the filter, which is located under the lid. This is easier to do with the help of a ring wrench, unscrewing the bolts. The air hose is attached to its inside, which should also be removed.

Finally we got to the carburetor of the device that can be disassembled. After disconnecting the fuel hose leading to it from the tank, t.E. Removal of the clamp, the hose returns, trying to remove it from the nozzle. Do the job carefully. After all, if there is fuel in the tank, it will definitely differ.

The carburetor is installed on the engine using two bolts, for unscrewing which the clutch head is required. When unscrewing the second bolt, try not to lower the carburetor so as not to damage the spring suspension.

The next step. Return the spring. The operation is more convenient to carry out on the side where it is attached to the motor. Now you can delete the cable responsible for the position of the lid, carefully turning the carburetor counterclockwise.

After removing the carburetor, unscrew the bolt with which the fuel chamber lid is attached.

Cleaning is carried out with a special liquid or WD-40 and a copper wire from which isolation is removed.

Finally, you can remove a plastic float located under the camera cover, which regulates the level of gasoline for which the pin is first removed.

The camera should be cleaned of plaque. The inside of the carburetor is abundantly moistened with WD-40 (or analogue), wiped dry. After repeating the operation, they clean the copper channels of the copper pipeline and blow them up, because their pollution is the main reason why the engine stops or does not start.

Read nozzle nozzle for snow cleaning

Having completed all the described steps, collect the carburetor in the reverse order.

After installing it in place, connecting the hose, air leaves the fuel chamber. This completes the repair.

After the manipulations described, the equipment will easily start and will work stably.

Repair of an electric mower

A longer winding grass around them can lead to stabbing knives. For repair, disconnect the device from the network and turn the cylinder in the opposite direction.

If the electrical appliance works silently, the drive belt breaks due to wear and requires repair: it can be stretched or torn. This means that you cannot do without a replacement for which you need to remove the protective cover.

The new belt is first installed on a small transmission of an electrical device, then put on a large pulley and rotates.

To replace the power cord of this electrical device, disconnect 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 a faulty power circuit breaker, which is simply replaced by a new.

The most common malfunctions of the lawn mower

As for problems with failure or jamming of the engine, they are practically not found in the lawn mowers of the cart type, which we consider in the article. These malfunctions are more likely inherent in the gas.type gasoline braids and make up almost half the reasons for their users’ contacts in service centers.

The lawn mower does not collect grass

The reason for this may be faulty or stupid knives. In order to avoid such a situation, you need to install new knives every season. You can do with the sharpening of knives at an angle of 30 °.

When hidden, it is necessary to protect yourself with special glasses and protective gloves. After sharpening, you need to test the balancing of the knives.

If a cylindrical mower does not collect grass, then it is better to sharpen knives in the service center. But you can purchase a sharpening device in the store and sharpen yourself, as shown in the video. To do this, you need to bring the cylinder of the turned off the braid to the position with the maximum interval between the blades. Then the abrasive strip is glued to the sharpening device, and the cylinder is transferred to the position in which the blades relate to the abrasive. The mitch needs to be turned on for short intervals of time until the blades become sharp.

Recommendations for storage of gasoline trimmer for grass in the offseason

Placing a trimmer for storage grass, it is worth filling the gearbox with a sufficient amount of oil. Then you need to clean the air filter, partially disassemble, blow and rinse the unit engine. Having dried all the mechanisms, lubricate moving elements. To carry out the processing of the piston system with oils, it is necessary to first extract the spark plug. Then you need to move the piston to the extreme position, then pour a small amount of oil into the candle hole and make scrolling the crankshaft. If the gasoline trimmer for grass in the offseason is not planned to be stored in the house, it is recommended to tightly wrap the engine of the unit with an oiled rag. This will avoid the development of corrosion on the surface of important components of the mechanism.

If your lawn mower starts up, but does it not as easy as we would like, we suggest using the following tips:

• Put the tool on the side so that the air filter is at the top. What will it give? The fuel mixture will fall exactly into the bottom of the carburetor. You can still remove the air filter and pour a couple of drops of the mixture into the carburetor and then install all the parts in place. The tool will start on the first attempt!
• Perhaps the problem is in the candle, and then, unfortunately, the previous method will not help. But there is another! Twist the candle, check it for performance and dry the combustion chamber. If the part does not show signs of life, replace it with a new.
• A universal advice that will help to start a lawn mower and a saw with a snowman. But it acts if the spark plug is working, the fuel mixture is fresh, air and fuel filters are clean. So, we close the carburetor damper and perform one movement by the starter. Next, open the damper and again twist the starter 2-3 times. We repeat the procedure, after 3-5 cycles the engine will begin to start.

How to clean and store a tool?

During the operation of the lawn mower, monitor the state of the engine cooling system. The channels available in the starter housing, as well as the cylinder ribs, should always be clean. If you ignore this requirement and continue to operate the motorcycle, then you can disable the engine due to overheating.

Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair

Before cleaning, let the engine cool down. Take a brush with a soft pile and clean the outer surface from dirt. Cleaning plastic parts is carried out by solvents, including kerosene, or special detergents.

After the summer season, the lawn mower should be prepared for long.term storage. To do this, the fuel mixture is drained from the tank. Then the engine is launched in order to develop fuel residues in a carburetor. The entire tool is well cleaned of pollution and sent to “hibernation”.

As you can see, it is possible to repair the malfunctions of the household lawn mowed on their own. Service services should be contacted in case of serious breakdowns. In this case, the cost of repairs with the price of a new lawn mower should be correlated. Perhaps it will be more advisable to buy a new tool.
