The gas trimmer Does Not Start

WHY THE LAWN MUTER WON’T START. TROUBLESHOOTING

WHERE TO START THE DIAGNOSTICS OF THE MOWERS If the mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main components and assemblies. The check algorithm is as follows:.Fuel tank (fuel quality);. Spark plug and spark plug channel;. Air filter;. Fuel filter;. Breather;. Outlet. These nodes are most often the source of major problems that can be eliminated after a thorough inspection.

Checking the fuel mixture Before starting the engine of the gasoline streamer, check the presence and quality of the fuel mixture. Do not save, do not be greedy and "do not be clever" 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 amount based on real needs. Excess gasoline remaining after operation loses its quality over time.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 cause. Here, for repairs, an ordinary candle wrench is suitable (every motorist probably has) and a spare candle.

-We unscrew the candle and wipe it;. Dry it thoroughly (it is not necessary to ignite it);. We drain the excess fuel in the chamber through the candle hole and dry it;. Clean the old candle from carbon deposits using a file or a ladies’ file;. Expose a gap with a distance of 1 mm ( you can check with any coin); We return everything to its place and try to start the trimmer. If the candle is working, the socket where it is located is completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle gives out, there is simply nothing to light up in a dry chamber.

If the trimmer motor still does not start, a reason such as the absence of a spark due to poor contact between the spark plugs and the high-voltage wire should be ruled out. If the connection is of good quality, but there is still no spark, most likely your ignition unit has "flown". Here it will not be possible to do without a master, since the part is not repaired, but is sold as a single unit.

Diagnostics of lawn mowers filters Another reason why the gasoline scythe stalls is the air filter. To eliminate it, try removing the filter and starting the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow through and thoroughly clean the old one. The petrol trimmer may not start due to a dirty fuel filter. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction inlet without a filter at all, this is prohibited by any operating instructions. Haste can turn into repair of the engine piston group.

MORE COMPLICATED REASONS FOR LAWN MOWERS FAILURE If the step-by-step troubleshooting algorithm fails and your streamer still won’t start or stall, it’s worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. Do not use needles and wires, as the bore may be damaged; Worn carburetor gasket. Exit. replacement of a failed gasket; Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing it with a suitable pressure gauge. Watch the readings: if they do not change, everything is fine, but if the pressure starts to fall, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

It is recommended to dry the candle channel for at least half an hour. However, in no case should you resort to calcining its elements. After all, heating the spark plug can lead to its final damage.

What to do if the function block was serviced in accordance with the above recommendations, but the trimmer does not start, there is still a spark? In this case, it is worth treating the threaded connection with gasoline. The latter does not need to be abundantly impregnated with fuel. It should only be slightly moist.

Such actions should be taken to ensure ignition. After all, no matter how strong a spark the candle gives, in an absolutely dry chamber there will simply not be anything to ignite.

If even in this case the trimmer does not start, it is worth evaluating the quality of the contact between the high-voltage wire and the candle. In the absence of a spark (if there is a reliable connection between these elements), most likely, the problem is caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of wizards who will reinstall the node.

How to prevent sudden breakage during trimmer operation?

In order for the unit to always be in a functional state, it is worth following a few simple rules:

  • Conduct a timely, regular technical inspection of the main mechanical components of the device.
  • Fill the trimmer with only fresh fuel, the quality and origin of which is beyond doubt.
  • After each use of the tool, check whether oxides and carbon deposits have formed on the surface of the ignition system.
  • Avoid heavy load on the trimmer during work.

In order for the unit to remain in working order, it is necessary to properly prepare it for storage in the winter. First of all, you should completely disassemble the instrument, and then flush and clean the constituent elements. It is also important to inspect functional blocks for damage, if necessary, eliminating deformation of parts, all kinds of distortions, gusts of materials.

The main malfunctions of gasoline and electric trimmers

Lawn mowers and electric trimmers, apart from damage to the boom and mowing head, mostly occur in the engine area.

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when started, then a flooded spark plug may be the cause. Here, for repairs, an ordinary candle wrench is suitable (every motorist probably has) and a spare candle.

  • We unscrew the candle and wipe it;
  • Dry it thoroughly (do not ignite);
  • We drain the excess fuel in the chamber through the spark plug hole and dry it;
  • We clean the old candle from carbon deposits using a file or a lady’s file;
  • We set a gap with a distance of 1 mm (you can check with any coin);
  • We put everything back in place and try to start the trimmer.

It is necessary to dry the canal for at least 30–40 minutes. Otherwise, there is a risk of re-filling and a new candle.

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

Lawn mower. On hot it stalls. Possible cause and remedy

Immediately I draw your attention to the chagrin that this is not a carburetor. (My Facebook website.

The 2nd reason why the car won’t start is because the fuel injectors are leaking.

In fact, everyone knows that a nozzle must supply fuel to the combustion chamber under pressure, but it will not be able to do this if the nozzle body is leaking. In this case, the mixture will be rich in fuel and poor in air.

If during the check it was found that the injectors were no longer tight, then they must be discarded immediately and new ones installed. The problem is that even cleaning with ultrasound will not help solve this.

A further prerequisite for not starting the car is that the high pressure fuel pump is faulty. The problem lies in the high pressure fuel pump. Husqvarna r 53 mower starts poorly and troit better when hot.

It will not be difficult to check this, and even the most inexperienced driver can handle it. In order to check the performance of the plunger pair, you just need to pour cold water on the back of the high-pressure fuel pump in order to cool it.

If after that the engine starts immediately, then the defect lies only in the plunger pair.

In fact, when an engine that runs on diesel fuel does not start, the drawback may not only be in the plunger pair. If the problem is on the diesel engine, then in addition to this check, you also need to check the drive shaft oil seal and the high pressure fuel pump bushings.

These were the main reasons why a heated car engine might not start. If all these manipulations did not help, then you should look further. But most often, drivers who are faced with this problem are helped by checking these particular main components.

One way or another, the problem here lies precisely in the fuel system. Also, do not dismiss the fact that the fuel may not be suitable to ignite properly.

The problem with fuel is described for a carburetor engine, but the engine, which is controlled by an electronic control unit, may not start for the same reason.

Rules for the operation and storage of lawn mowers

In order for the lawn mower to start well in the future, you need 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 housing, as well as the ribs of the starter;
  • If necessary, use solvents, kerosene and other detergents for cleaning;
  • Do not clean the tool "hot". let it cool down;
  • Strictly follow the instructions for the operating mode, otherwise you may overheat the engine;
  • If you do not plan to use the lawn mower in the next month, the fuel mixture must be drained from it, because Over time it breaks down into heavy fractions, which will definitely clog the carburetor channels;
  • After draining the fuel, let the trimmer run at idle speed until it stalls, this will help completely remove the remaining working mixture.

Before winter storage, follow these steps:

The Benzotrimmer Does Not Start
  • Disassemble the braid completely, rinse and clean all the parts you can;
  • Inspect the parts for damage, if necessary, eliminate distortions, tears, bends and any other malfunctions;
  • Fill the gearbox with sufficient oil and clean the air filter;
  • You can partially disassemble the motor, rinse, blow out and grease all moving parts;
  • In order to lubricate the piston, you need to unscrew the spark plug, lift the piston to the dead center with the starter, pour a little oil into the spark plug hole and turn the crankshaft a couple of times;
  • If you are storing the lawn mower outside the house, wrap the engine with oiled rags.

Remember, careful adherence to the rules will allow you to forget that it is bad to start the lawn mower for several seasons.

Perform cold starts correctly!

Petrol trimmers often do not start after trying to "put them into operation" after long-term storage. Failure to launch in this case is often caused by incorrect user actions.

If you are faced with exactly this phenomenon, then during a cold start you need to close the damper, and then pump a small amount of the fuel mixture into the carburetor. Then pull the starter handle until you feel resistance, then start the trimmer with sharp and energetic movements.

The main thing. Fuel mixture!

In this case, the remnants of plastic dissolved in an aggressive environment do such terrible things in the combustion chamber that you will definitely not be able to do without completely overturning the mechanism. But you will certainly remember forever how to properly store fuel.

What to do when the fuel was definitely normal, there is a spark, but the petrol trimmer will not start? It is possible that you just filled the candle with gasoline. In this case, it must be turned out, wiped with a clean cloth and dried. By the way, it will be quite useful to check the candle itself for performance.

What to do when petrol trimmers won’t start?

The petrol trimmer is a surprisingly useful tool that can be used to mow not only a miniature front lawn, but a whole lawn of considerable size. Unfortunately, there is nothing eternal in this world, and therefore you may face the fact that petrol trimmers do not start.

It often happens that users of this kind of cars are trying to "save money" by pouring into the tank not fuel with a normal octane number, but something incomprehensible that has been in a plastic canister for almost a dozen years.

reasons

There are not only situations when petrol trimmers do not start, but there are cases when after starting they work for a couple of seconds and then stall. Inspect the spark plug again: if it is "thrown over", and this situation repeats even after wiping and drying it, go to the "revision" of the air filter.

Most likely, it is completely oiled and needs to be replaced. If everything is fine with the filter, it may be that the ignition coil is out of order.

In the case when the petrol trimmers do not start, and you have done all of the above, the muffler may be clogged. It must be dismantled, burned on a burner, after which all carbon deposits can be easily shaken out.

Even if your trimmer won’t start even after such bullying, you cannot do without disassembling the carburetor. It may very well be that the falling needle in it is to blame for everything. In any case, disassembling and flushing this capricious mechanism will certainly not interfere.

In general, when the trimmer began to be capricious and stall, it is advisable to carry out full preventive measures: completely change the fuel mixture, try a different oil, and also change the spark plug without fail. Practice shows that in many cases cheap low-quality candles are to blame.

We’ve covered the most common reasons why the trimmer won’t start. If the matter is in something more "exotic", you cannot avoid going to the service center. You will surely find smaller and more obvious breakdowns yourself.
