Gap on a candle of lawn mower Stihl FS. Rules for the operation and storage of gasoline baskets

Why does a trimmer for STIHL grass does not develop speed: the reasons how to get a STIHL motorcycle

Before starting the gas trimmer for the grass, it is necessary to regularly check the gearbox. The lack of oil or its small amount increases the friction of the gearbox operating at fairly high speeds. This leads to overheating and transmission. Gearbox Grand Lawn Model. Prevents such damage during operation and helps regular inspection.

If an insufficient amount or lack of fat is found before starting a gas braid in a gearbox, Litol is inserted into the case. To do this, unscrew the screw on the bend of the gearbox and the Litol syringe in the amount of 1-2 ml.

What to do if the chainsaw does not start?

There are many factors why the chainsaws will not start if you follow the starting technology. The most common reasons and solutions:

candle, lawn, mower, stihl
  • There is no spark plug. Replacement or drying is required upon receipt of water;
  • The problem with the supply of gas to the filter. Purging the fuel hose or filter, replacement;
  • Clogged fuel or air filter. Needs high.quality cleaning.

If these simple tips did not help, you need a complete diagnosis of the problem. It is recommended to return the chainsaw to the service center, where they can check the compression of the cylinder and crankcase, as well as the operation of the carburetor.

The correct launch of the chainsaw provides the stable and reliable operation of this tool. When starting before sawing, it is necessary to properly prepare and refuel the fuel mixture, adjust the main structural elements. It is important to consider weather conditions, as well as the features of a particular model.

  • How to start a three.dimensional motor or bush?
  • Starting the brush for the first time or after prolonged downtime
  • Refueling through the candles for candles
  • Checking the ignition system
  • Engine cleaning
  • Sparkling check
  • Unstable work of the carburetor
  • Drain the fuel tank

How to launch a trimmer for grass. This is a question that the owners confuse in the case of failure of the device. And after the successful repair of the trimmer for the grass, the owner tries to avoid repeating the same situation.

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:

  • Fuel tank (fuel quality);
  • Candle and candle channel;
  • Air filter;
  • Fuel filter;
  • Breather;
  • Graduation channel.

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.

If the trimmer engine for grass still does not start, such a cause as the lack of spark due to weak contact between candles and a high-voltage wire should be excluded. If the connection is of high quality, and there are no sparks, most likely, you have “flew” the ignition unit. Here you can’t do without a master, t. to. The part is not repaired, but sold by a whole knot.

Diagnosis of the filters of the lawn mower

Another reason why the gasoline braid for grass stalls is an air filter. To exclude it, try to remove the filter and start a trimmer for grass without it. If it turns out, then you will have to change the air filter to a new one, or at least blow and carefully clean the old.

You can’t start a gasoline trimmer for grass due to contamination of the fuel filter. This is the next stage of our algorithm. Here we check the state of the filter element and, if necessary, change it with the new. When replacing, try not to leave a suction pipe without a filter, this is prohibited by any operating instructions. Rush can turn into the repair of the piston group of the engine.

Sapun and graduation channel

Often, “delicate” branded models of benzos are not launched and stall due. The main function of this element is to align the pressure in the gas tank. When clogging this node, a vacuum is created in the tank that prevents the supply of fuel. Eliminate the malfunction can be cleaned by cleaning the sounds. You can use a regular needle for cleaning.

The normal operation of the cos with internal combustion engines can be disturbed due to the entry of dirt into the exhaust channel or clogging of the muffler grid. There is such a problem on the models of the older generation. You can solve the issue with traditional cleaning and removal.

Candle examination, problem identification

Before putting a new candle, make sure that the problem of the device is connected with this particular detail. First, take a look at the heat cone of insulation and electrodes. Their appearance will tell you about the operation of the engine and the quality indicator of the fuel mixture is a lot.

If you changed the candle, the ignition recently, inspect the above nodes for serviceability, check if the sparkle of the spark plug on the chainsaw is installed correctly. A careful inspection of the main units of the unit will allow you to extend the operational period of the tool and will give you the opportunity to save personal funds.

Perhaps, with the last replacement of the candle, you chose the unsuitable for your saw. If the case of this part is covered with an oil dark layer, this signals that the candle is too cold for your tool (inappropriate for the engine).

Important! Sometimes the same “symptom” speaks of an inflamed oil level of the crater, worn rings of the piston and cylinder, as well as an excessive amount of oil in the mixture that you use for a 2-stroke engine.

Nar is dark, but dry can indicate a cold candle that is not suitable for the engine of your saw. The same “symptom” also manifests itself with intensive operation of the device at idle speed or at low speeds in working mode.

If the chainsaws are poorly started, then perhaps it fills the candle on the chainsaw. You can solve the problem by reading the article on the link.

But how to understand that the selected candle for the chainsaw engine is too hot? The cone of the details will be dry, almost white, without a hint of traces of oil (only sometimes traces of melting can be noticeable). This may say that the candle was installed incorrectly.

If the candle is selected correctly (and installed also correctly) traces of melting or soot on its cone will not be. Brown or gray (light shades) raid can be considered the norm, which indicates that this node operates without problems.

Fuel system malfunctions STIHL 180

In some cases, as a rule, if there is a spark on the spark plug, when examining it, you can notice that it has a wet plaque, this indicates an excessive supply of fuel to the combustion chamber and, as a result, the impossibility of ignition of the fuel mixture.

The candle floods

Among the people, a phenomenon in which the spark cannot ignite a large amount of fuel. it is customary to call the candle. The cause of the malfunction lies in the carburetor, or in the wrong launch of the cold engine. If a malfunction is detected, first you need to carry out the “purge” of the engine.

Magnetic diagnostics

Magneto is a key component in engine ignition systems. This is the core of the coil, which is surrounded by the primary and then secondary winding. If this element is faulty, the spark plug does not ignite and the fuel does not ignite.

You can check the performance of the magnet using a tester. To do this, follow the following actions.

  • Adjust the tester correctly: use the resistance measurement function and install 200 Ohms to measure the primary winding.
  • The first electrode of the measuring device is aimed at the Magnit magnet, and the second. On the output contact. If the primary winding is in order, the values ​​should be from 0.4 to 2 Ohms.
  • Install the 20 COM switch to diagnose the secondary winding. Then send the first probe to the candle cover, and the second probe to the “mass”. If everything goes well, the numbers will vary from 4 to 6 kOhm, depending on the model of the trimmer for the grass, whether it is Patriot 547, Husquarna 128 R or another brand of technology. If the chain is torn, the infinity value appears on the tester screen. And if a short circuit occurs, zero will appear on the display.

The second method

If you cannot use a tester, there is another way to perform a test. It is important not to touch the cylinder by the electrode, otherwise the coil will be damaged.

  • Remove the spark plug lid. Do not unscrew the candle, as this will preserve the compression.
  • Then you need to take a nail with a lid removed and tightly insert it into the lid.
  • Then the nail coating should be securely attached to the cylinder using a dielectric. In this case, the electrode should be at a distance of 5.5-7 mm from the cylinder body, but not touch the mass.
  • Then the starter must simulate the engine starting when the ignition button is turned on. In this case, you should carefully monitor the spark and try to determine its color.

Important! A strong shine of a white or blue shade indicates the perfection of the magnet. If it is weak, as well as orange or yellow, the magnet is damaged.

When making a diagnosis, one important point should be remembered: not heated magnets in any conditions can create a powerful spark. But if it is faulty, it stops generating the current when heated, and the trimmer for the grass will not start. Later, after cooling, the coil again returns to the working level, the motor unit turns on and works idle for some time or under load until the magnet temperature rises again. In this case, the part should be replaced by a new.

The note! In some situations, the heating problem is not associated with a malfunction of the coil, but with the spark plugs. This means that both parts should be checked.

Inspection of the reducer of the lawn mower and its lubrication

Checking the gearbox before launching a gasoline trimmer for grass should be created on a permanent base. The lack of lubricant or its small amount increases the friction of the gear transmission of a gearbox that works at fairly large speeds. The result is overheating and gears. Motokosa gearbox fails. To prevent the appearance of such a breakdown during use and is helped by constant inspection.

If, before the start of a gasoline braid for grass, the missing amount of lubrication in the gearbox or its absence, Litol is laid in the case. To do this, you need to unscrew the screw on the gear housing and pace the “lilest” in the amount of 1-2 ml.

Working with a gasoline trimmer for a long time, every 8-10 mothers add grease to the gearbox of the bar.

If everything is in order with electrical equipment, then we check the carburetor.

Vacuum carburetors are put on trimmers for grass. When disassembling it, cleaning or washing, you need to be extremely careful. in no case do not disassemble the lower part of the carburetor where the primer is located. Air filter (it is visible if you remove the protective casing from the carburetor) should be washed with detergents. Best. for washing dishes. After drying, we put it back. Rinse the carburetor with clean gasoline and blow out all the holes by the pump. We also wash the filter of the gas pipeline, then we dry everything and collect everything. Usually, after all manipulations, the trimmer for the grass begins to work.

Thin cable instead of fishing line, whether it is worth placing it on a motorcycle?

This thought comes to mind almost everyone who had to pump out 10 acres overgrown with high grass. At first glance, the idea seems good. The cable is stronger than the fishing line, not so wear out. However, not all so simple.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

  • Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
  • After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

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

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

The lawn mower starts poorly? Adjust Magneto’s gap

As the experience of operating benzos, in particular Chinese production shows, they often have problems in the launch system, so they are often difficult to start. Problems are usually related to the flywheel magneto.

For those who are unfamiliar with this unit, we remind: this system consisting of ignition coil, spark plugs and flywheel with magnets. We have to deal with the clearance of Magneto, more precisely, with the gap of the ignition coil and its guaranteed exhibition. It is because of it that problems arise in Chinese units, which for several years were operated in domestic conditions or in the conditions of the Housingire. But it happens that even in new products it is difficult to start, especially for cold. And in this case, usually problems with the launch are related to the gap of magneto. Most people who operate the lawn mowers expose the Magneto gap of 0.4 mm, as recommended by many manufacturers. What will happen if this gap is adjusted and set 0.25 mm? It turns out that when it is reduced, the electric spark becomes thinner, smaller and practices every beat even with slow speeds of the Magneto flywheel.

That is, consciously reducing the gap, we thereby increase the likelihood of a normal launch of the lawn mower without any excessive physical exertion and shortness of breath even when starting a cold engine.

Gap and procedure for its exhibition in different cases

As a template, a strip of the required width and length carved from a conventional plastic bottle, for example, from under Pepsi-Cola, can be successfully used to put a gap of magneto.

It is only necessary to install it last, so as not to damage when carrying out repair work, using the same hair dryer for any purpose. After all, if it is crumpling from the effects of hot air, then there is no need to talk about the accuracy of the gap of Magneto. It is with the help of a spacer carved from a plastic bottle that you can with high accuracy set the Magneto gap 0.25 mm, since its thickness is exactly the same. To make sure of this, it is enough to fold the strip four times and measure its total thickness with a caliper, which will be exactly 1.0 mm. We put a spacer cut from a plastic bottle on the magnets of the Magneto flywheel, set the ignition coil in place and fix it with strong bolts of 8 by 8, after filling the holes with a thread on the case with a threaded latch.

We apply it on the bolts, twisting which, you must not forget to fix the terminal of the mass. It is better to use an electric screwdriver at the same time. We squeeze the bolts with a regular hand screwdriver with a hexagonal bat to the limit, since the use of a M-shaped hexagon can lead to a breakdown of the faces of bolts.

It remains, turning the flywheel with magnets, remove the plastic spacer and, continuing to rotate it, check the quality (uniformity) of the clearance when it turns from 0 to 360 degrees, which, with this approach, is ideal. Some use the Magneto’s gap folded by half a photochex leaf, which is also permissible, but the use of a spacer from a plastic bottle gives the best result. over, it can be used reusads dozens of times.

It remains only to install body parts and you can run the engine to test how it starts and works. Sometimes during operation, the ignition reel reels are deformed to the magneto housing, which does not allow you to reliably install it, since the holes in the coil and on the engine body do not coincide.You can, of course, try to straighten out the defect, but it will be more reliable to put a new coil, especially since it is not too expensive.All further actions are similar to the above case, unless the heads of fastening the spark plots can not be under the hexagon, but for the wrench and the cross.shaped screwdriver. But this does not change the essence of the matter: the tightening of these bolts should be guaranteed to be reliable, as in the first case. To evaluate the quality of the work done, it is necessary to make sure there is a spark between the electrodes of the candle visually after the final assembly of the engine. To do this, we connect it to the mass and begin to turn the engine using the starting device of manual or electric. The check for the spark has one nuance. If you sharply pull behind the kicks starter, then the spark will appear even with slightly faulty magnets of magneto and even completely non-working ignition coils. In this case, the presence of a spark is not yet an indicator of the serviceability of the ignition system.The quality of sparking can only be judged by its appearance, when the flywheel Magneto does not rotate too quickly, for which the kicks starter should not be pulled, but evenly and not to pull.

Only in this case, the engine of the benzotrimer or chainsaw will be started without problems, both in the morning and throughout the entire working day (respectively, the so.called hot or cold launch). If there is no spark with a slow movement of the starting device, then, most likely, you will have to change the ignition coil, set the gap of magneto or change the candle.The practice of putting a gap on benzos and chainsaws described above for five years has justified itself completely. There have never been complaints from users after such a repair. This really helps when starting not only Chinese gasosos, but also European and even branded. At all units, regardless of the manufacturer, putting the Magneto clearance 0.25 mm instead of 0.40 mm recommended by manufacturers, gives excellent results. Some people offer gaps 0.10-0.15 mm, but this. After all, there is a certain thermal expansion of the parts of the ignition system, the housing itself, the gas mower or chainsaw crankcase, and such a small gap can disappear altogether, which can lead to breakdowns (burning out), first of all, the ignition coils. Therefore, a gap of 0.25 mm is from all points of view optimal.

How to lubricate a trimmer gearbox for grass / Gearbox gearbox / Reducer Motokosa

Lubricate a trimmer gearbox for the grass at least once a year, but it is better to inspect the lubricant after every 20-25 hours of work or when the gear noise in the motorcade gearbox appears. How to lubricate the gearbox gearboxes. For lubrication, at first you need to clean the cork itself and the place around the traffic jam and the remnants of the grass, so that they do not fall inside the gearbox when filling it with grease. Then you need to turn out the cork for the lubrication of the gearbox (for example, the Echo lawn mower is a key for “17”, in Husqvarna-a 6-garnet on “5”, for Chinese lawn mower-the key on “12”). It is better to use the same manufacturer as your trimmer for grass or just from world-famous brands, such as Oleo-Mac, Stihl, Husqvarna, Oregon, Liquimoly, Litol-24, Azmol 158 and T.D., If only it was not a fake! The tube, if new, print, removing with your fingers a cork or piercing the cover with the back of the lid in the nose of the tube. Then we put a trimmer for the grass on the left side, and rotating the knife with one hand (so that the gears are smashed and the entire volume is filled), squeeze the lubricant from the tube with the 2nd hand through the hole inside the gearbox before its full filling. Then we twist and clamp the trimmer gearbox for the grass and a tube plug with a lubricant. If the lubricant is not in the tube (and, for example, in the jar), take a honey syringe without a needle, take out the piston, fill the lubricant (with your finger) in the syringe, and then fill the gearbox of the trimmer for the grass from the syringe from the syringe.

Oil for 2-stroke engines of trimmers must comply with slightly different standards than oil for 4-stroke engines. Oil for the lawn mower should have a high degree of combustion so that the soil does not form on the internal parts of the fuel system (particles of soot can disappear and form scratches on the walls of the cylinder). Also, 2-stroke oil should dissolve well in gasoline and be designed to work at high temperature.

Taking into account such serious standards, modern manufacturers of garden equipment produce special lineups of 2-stroke oils, designed specifically for trimmers and motorcycle. Oils of manufacturers such as HADO and STIHL are ideal for this equipment, provide excellent grease and have a low level of fire.

Model FS 70 C-E

A middle class representative in the STIHL gasoline trimmers family. The power of the two.stroke engine of this lawn mower is 1.2 liters.With., And the width of processing is 25.5 cm. The main advantages of the model are a reliable and shock.resistant design with a fishing line 2.4 mm thick, which allows you to work confidently on large sites with wild hard grass. The task of the operator when handling the engine is facilitated by the ERGOSTART launch system. When turning on, the user does not feel jerks. the workflow begins softly and without vibrations. According to the quality of the result, we can say that the Stihl FS 70 C-E lawn mower even steadily removes the shoots of trees and stems of shrubs with a thickness of 4 mm, but there is also a disadvantage-there are high handakers. The cost of the unit is about 20 thousand.

The problems of the carburetor, as a rule, consist in clogging nozzles and other elements. For repair, you need to disassemble the knot and clean it. Perhaps an additional adjustment of the carburetor will be required.

You can clean nozzles and fuel channels using a pump or compressor. For adjustment, 3 screws are usually used:

STIHL 180 chainsaw. malfunctions and repair

There are a number of typical breakdowns, which are most often faced with owners of the STIHL MS 180 model. Having studied the reasons for their appearance, the roller will be easier to eliminate breakdowns with your own hands.

Why not start a chainsaw STIHL 180?

The main reason for this malfunction is the poor state of the spark plug Stihl MS 180. If it is dry, then the fuel does not fall into the cylinder. If the candle is wet, then you need to find the place of the fuel pipe.

In any case, for further work with the STIHL MS 180 saw, you need to unscrew the candle, clean it from soot and dry it. The same must be done with the details located under the candles. At the end, the candle will need to be screwed into place and continue to work with a saw.

Why flies a candle on the chainsaw of Stihl 180?

The essence of this breakdown is the problems with the carburetor. For repair, you will need to remove this element, as well as check its membrane. In working condition, the detail should be not only whole, but also elastic. If the membrane was boiled, then it will need to be replaced.

Before the reverse assembly of the STIHL MS 180 carburetor, it needs to be cleaned of dust and soot. To do this, use compressed air in the cylinder. After the node completely dries, it can be assembled and installed back on the chainsaw.

What to do if the oil does not enter the chain of the chain of the Stihl 180 chain?

If the chain is not lubricated on the German saw of the Stihl MS 180, then this indicates the blockage or malfunction of the highway through which the oil circulates. To solve the problem, you need to remove the tool handle, pull out the hose and clean it. After that, the hose must be installed back on the saw, and grease the installation site with a sealant.

candle, lawn, mower, stihl

Another reason due to which the oil is not supplied is the blocking of the STIHL MS 180 pump. To correct the situation, you will need to remove the pump and rinse it in pure gasoline. If this did not help, the detail will need to be replaced.

Stihl 180 chainsaw is stalling when pressing gas. how to solve the problem?

If the model stalls when typing a speed engine, then this indicates a clogging of the fuel filter. Because of this, the element is not able to pass the fuel that is necessary to increase the speed of the ICE STIHL MS 180.

In this case, it is necessary to remove the fuel filter and rinse it with clean gasoline. If this did not help, then you need to carefully check the factory air filter. If a large amount of garbage has accumulated in it, then it will need to be replaced with a new element.

What to do if the saw stalls at idle?

If the Stihl MS 180 chainsaw stalls some time after launch in idle mode, then this indicates a breakdown of the fuel pump. To make sure of this, you need to use the vacuummeter. If the device has shown the pump malfunction, then the mechanism will need to be replaced.

How to Fix a Trimmer That Won’t Start!

Another cause of the malfunction is the wear of the Stihl MS 180 seals. After a long use of a saw, they lose their shape and elasticity, missing a large amount of fuel. In case of wear of the oil seals, they will need to be replaced.

The chainsaws are poorly started on the cold. elimination of the breakdown

Most often, the cause of this malfunction is the initially incorrectly established gap between the ignition coil and the flywheel of the Stihl MS 180 chainsaw. In this case, you need to disassemble the tool and make measurements between contacts and flywheel.

If the gap is more than 0.2 mm, then it must be reduced using a pair of side screws. To do this, between the flywheel and the standard ignition coil, you need to insert a paper business card or calendar. After that, by turning the screws, the flywheel must be brought closer to the ignition coil so that they hold the business card. At the end, it remains to gently extract the paper and collect the saw.

The reason for the flooding and throwing of the candle on the chainsaw

Often, the owners of the chainsaw are faced with such a problem. floods the candle on the chainsaw. This should not happen, normally a candle should always be dry. Sometimes the owners use the term “throw a candle”. This describes the same problem. flooding the candle.

Let’s figure out the reasons for such a malfunction and find out why the candle on the chainsaw begins to fill.

After identifying the problem, try to immediately eliminate it. Follow these actions:

  • Check the condition of the stepsel fork. It is advisable to perform such a check every 15 working hours. If the engine operation is not violated, then the fork will be covered with soot-brown soot;
  • If the carcass is black, floods the candle due to the fact that the mixture of air and fuel in the combustion chamber is not balanced, and few air enters the air. You should also check the gap between the electrodes;
  • If there is corrosion on the fork or the distance between the electrodes is very large, the fuel mixture is depleted;
  • Wet from oil, the plug speaks of oil leakage;
  • If the deposits on the fork are light brown, and the gap is normal, nothing needs to be done with the fork-just install it in place and the chainsaw will work fine;
  • Black carbon car is removed with sandpaper, and the gap is regulated by pliers;
  • If the candle is very worn out, replacement is required. the degree of wear is checked by the candle tester. The weaker and more irregular the spark, the more worn out the candle.

The reason for the wet candle is the rewriting of the fuel. The imbalance of the fuel mixture in the case when there is not enough air in it, it can be caused by such factors:

  • low quality of gasoline (always refuel a high.quality fuel tool);
  • incorrect sequence of chainsaw launch;
  • clogging of the air filter and the need to replace it;
  • ignition failures;
  • not adjusted carburetor.

Important! Ignition adjustment is required only if the candle is wet! With dry candle, you should not interfere with the ignition.
