Fills a candle on a lawn mower

The main thing when installing a spark plug is that you first need to turn the candle out of hand for a few turns, and then take the key. If the candle went easily by hand, then it is installed correctly and can be wrapped with a tool (a candle wrench with a wrench). If the candle does not want to twist by hand, it is not worth tightening it with a wrench, since the candle has not gone along the thread and damage to the thread in the spark plug hole of the cylinder is inevitable and expensive repair of the trimmer engine will be needed. Looks like my first channel:.

Do not start the lawn mower. The reason is the gas tank krishka

For those who do not want to read the whole topic, in short. when the valve in the critical gas tank gets stuck, it does not enter the carburetor through the valve. That is one of the reasons not to start the lawn mower. Dal in pictures.

Having bought a Chinese lawn mower Werk WB-5300. Gulf of palivnu sumish at spіvvіdnoshennі 1:50, tobto 1 liter. 95 gasoline (at the Glusko gas station, refueling in a 5L metal canister), 20 ml is added. Two-stroke synthetic mastic. Having tried Verylube 2T FC. Synthetics depend on stable indicators. Zmіshuvati sumіsh zruchnіshe in lіtrovіy plastic dances. Tank from a set of mows all 600 ml.

And it was done with a 20 ml syringe. From the nearest pharmacy. It’s cheap and for sure!

Pouring the amount of money into the tank, pumping it with a primer and trying to start it. Here it is necessary to nagolosity, but for an hour to get the primer of the carburetor gasoline there, and after doing it, it was not possible to start a braid.

Gas tank crush. the reason for all bid

Having tried to spin the gas tank cry, she felt a characteristic zilch. The tse sound was sucked into the tank. Through the razrіdzhennya in the base gasoline did not enter the dvigun system. In order to ensure that the vapari gasoline was not taken out of the tank, and if the tank was damaged, the vacuum did not break out. a special valve system was used in the transfer.

Opening in the valve of the gas tank valve

Through trivale zberigannya, the valve in the critical gas tank can get angry (any rubber bands can get angry). We can’t go into the tank with a fireball. The lawn mower brush has started to clean the valve! Krishka can be brought in and new, the blessing of kostu won less dolar

Otozh, the main symptoms of a faulty valve in the legacy of why the lawn mower does not start:

  • When krishka is seen, suck it in;
  • Through the vacuum at batsi, the crush is tightly spinning;
  • Before the hour of pumping the primer, the sums through the pipes are then strongly “run back” into the tank, I want it to be pumped;
  • The valve in the valve is to blame for the inlet to the inlet and blowing only in one direction, so that if you try to pull it in, it is guilty to pull in from the side of the tank;
  • If the pass valve is on the offensive side. you will always bet on gasoline;

Insufficient compression

If the compression is insufficient, then in most cases it will not work to start the engine. You can use a car compression gauge to check compression.

  • Unscrew the spark plug from the engine cylinder.
  • Screw the compression gauge in its place.
  • Begin to pull on the starting cord as you would when starting lawn mowers. Do this until the arrow on the measuring device stops moving upward. This value will show the compression force of this engine.

What compression should be? Normally, the compression should be at least 8 kg / cm 2. Although even at 8 kg / cm 2 some engines do not idle and stall, since the fuel is not pumped up sufficiently. In case your lawn mower does not pump above 8 kg / cm 2, you will have to check the cylinder, piston and rings.

Also, poor compression can be due to a loosely screwed carburetor. Check if it staggers. If so, tighten the hardware that holds it securely. Also, if the carburetor is poorly screwed on, you may notice that gasoline drips during operation.

Causes of breakdowns of gasoline and electric trimmers

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

Electric trimmer vibrates

Many mower users have noticed that some time after the start of the machine, it begins to vibrate strongly. On some trimmers, mostly in more expensive models, an anti-vibration system is installed in the form of shock absorbers located between the engine and the boom. But in some cases, even she does not save from strong vibration. The reason that a strong vibration appears in the trimmer may be a small amount or a complete absence of lubrication on a rigid or flexible shaft located inside the apparatus rod.

Rigid shaft lubrication is changed as follows:

  • Unscrew the gearbox located at the bottom of the rod;
  • After removing the gearbox, you will see the end of the shaft, which must be pulled to remove the part;
  • After removing the shaft, it must be abundantly lubricated with special grease "Shrus-4" or the usual. "Litol-24";
  • Apply a small amount of grease to the shaft and smear it evenly along the entire length of the part, including the splines at the ends of the rod (if they work, the shaft will have to be replaced);
  • After lubrication, insert the shaft back into the rod and replace the gearbox in its original place.

The flexible shaft is lubricated as follows:

  • Unscrew and remove the mowing head;
  • Remove the rod from the electric motor by unscrewing a couple of bolts;
  • Pull the flexible cable out of the rod;
  • Lubricate the entire length of the cable with grease.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the rod, after which, as it moves inside the pipe, you should apply lubricant to the part and distribute it evenly over the surface. Then insert the flexible shaft rod into the electric motor and secure it.

Exhaust channel

The reason that the trimmer has significantly lost power, and when trying to increase engine speed, it picks up slowly, is often a clogged exhaust channel through which exhaust gases come out of the combustion chamber.

It is necessary to remove the muffler so that no fumes get inside the cylinder. Next, clean the exhaust channel from carbon deposits.

After this procedure, the weak power of the unit and a slow increase in the speed of rotation of the mowing head will no longer upset you.

Why the gasoline trimmer won’t start

The reasons why the petrol trimmer stopped starting may be different, so a step-by-step diagnosis of the device is required.

Breakage of petrol trimmers

Typical breakdowns of a gasoline trimmer, which the owners of this unit most often encounter, are as follows:

  • Engine breakdown;
  • Carburetor problems;
  • Fuel supply problems;
  • Muffler malfunction;
  • Gearbox breakage;
  • The starter has broken;
  • Air filter problems;
  • Gas tank breather clogged.

Need help, advice, HY 30.СС does not start hot

If the fuel by itself then goes away, then it comes back, there is a possibility that the pressure in the line is to blame (sometimes excessive, sometimes insufficient) and it seems that it is connected either: a) with temperature. Maybe when driving, the fuel in the carb boils from overheating of the engine? What temperature after a long ride? B) or over time. Then it is possible that somewhere something is hammered. Not fatal, but still. For example, an air filter (dust, excess oil on it), drainage in the tank cap, fuel filter, pinched fuel pipe, etc. As a result, it sucks fun, but it can’t quickly)))) Or maybe the fuel pipe is punctured, then on the contrary it sucks in air instead of fuel. On a cold one, it can be squeezed better and does not suck so well, but on a hot siphonite.

PS Purely from theory, a hot engine is more difficult to start if the mixture is too rich. And for starting a cold engine, on the contrary, this is a plus. Turn out the candle and if it is all soot or filled with fuel, then you need to be poor. And try the iridium candle. With a problematic engine, it works a little better, especially when overflowing.

Why won’t the petrol trimmer start? Causes and their elimination

In the near future, the gasoline trimmer acquired the status of the 1st of the main tools in the arsenal of summer residents. And this is logical, because a motorized scythe allows you to quickly put your personal plot in order. But from time to time it happens that the trimmer does not start hot or even cool. In such situations, it is necessary to establish the cause of the malfunction without the help of others. Let’s figure out what to do if the trimmer won’t start. The reasons that most often lead to such troubles will be discussed below.

The lawn mower won’t start after winter

In such cases, the unit must be serviced. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to fuel quality and octane number.

It should be borne in mind that the products of such well-known companies as STIHL, Husgvarna and other brands will not run on cheap, low-octane gasoline. Suitable fuel for them is from the AI ​​grade. 92 and higher from car gas stations and then from well-recommended ones, since there is also bad gasoline at gas stations. The use of high-octane and high-quality gasoline will determine how long the lawn mower will be used and how long it will last.

It is necessary to take into account one more fact that with a long storage of a diluted fuel mixture, its working qualities drop, which also leads to consequences in which the lawn mower does not start. Therefore, it should be diluted in portions, that is, the amount of the mixture that is produced at a time. The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict observance of the correct proportions will at least save you from several questions, why the lawn mower does not start and what to do in such cases.

Many gardening tools are useful and effective, but there are times when the equipment refuses to work. Among them was a trimmer that can mow both a miniature lawn and huge lawns.

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 damp. 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.

Checking the fuel mixture

Let’s say your trimmer won’t start. In this case, the first step is to check whether there is enough fuel in the tank, and also to assess the quality of the fuel mixture. It is necessary to refuel the motorized unit with exclusively high-quality gasoline. It is recommended to use fuel with a grade not lower than AI-95. Filling the trimmer with fuel of unknown origin not purchased from a gas station can cause frequent tool malfunctions. This can cause damage to the piston-cylinder system. In this case, repairs often exceed the cost of the device itself.

Why won’t the petrol trimmer start? Improper preparation of the fuel mixture, which consists of oil and gasoline, can also lead to this. The proportions in which these components are connected are indicated by the manufacturers in the trimmer instruction manual. It is highly discouraged to prepare the fuel mixture in large volumes, that is, for the future. Indeed, with long-term savings, there is a loss of the defining properties of the substance. Therefore, if the trimmer does not start, it is worth draining the old fuel and using a freshly prepared fuel mixture.
