Mower Shtihl FS-38 and 55 (Stihl FS) - operating instructions, do-it-yourself repairs, how to remove the coil from the trimmer and start the lawn mower

It is natural for a person to ennoble the place in which he spends the lion's share of his time. City residents resort to the services of designers, or they themselves try to change something in their home, buy new furniture, wallpaper, so that when they come home after a hard day, they can mentally rest and relax in a favorable environment. Residents of their own houses located outside the city have completely different concerns and requirements. It is necessary to promptly mow shrubs, grass, various dead wood, and carefully monitor the condition of the plot and garden. It is clear that this requires slightly different means of achieving comfort. And here a new brainchild of engineering comes to the fore - mowers.

About the manufacturer Stihl

The history of this German brand begins in 1926. At the initial stages of its development, the company was engaged in the production and sale of various components for washing and steam machines. It all started, like many companies, with small production and a narrow focus, which made it possible to focus on the quality of the products produced.

In the early 30s, the first STIHL chainsaw was released, distinguished by its convenience and functionality even in those days. The company is developing at a rapid pace, constantly introducing new tools, which gives it the opportunity to enter the international market. And already in 1931, the first regular deliveries of products to Russia were organized.

To date, the company has expanded its activities in more than 160 countries around the world, opening new centers and production branches in Switzerland, China and many other countries. This is understandable, because the company’s assortment is impressive: motor drills, gasoline sprayers, mowers, gasoline trimmers, chainsaws and much more. I would like to note that Shtil chainsaws are very popular due to their functionality and reasonable price.

Features and best models

The mower deserves special mention, notable for its versatility, reliability and ease of operation. The company's specialists have developed many types of braids, with different characteristics and applications.

For example, the range of lawn mowers is designed for mowing grass over large spaces . For this purpose, a self-propelled wheeled system was developed, with the help of which it became possible to care for a large area without spending a lot of time and effort. A brush cutter is perfect for decorating shrubs, giving them some artistic image and texture. And if you need a lawn mower for tall grass and uneven areas, then follow this link and get complete information on selecting this type of equipment.

If you need a more subtle approach to grass cleaning, for example, around flower beds or between trees, then a gasoline trimmer, designed for accuracy and precision, will do the job perfectly. The company's specialists took into account all the nuances and possible difficulties when working with scythes, so they equipped them with nylon strings, which prevent mechanical damage to trees.

A special AutoCut trimmer head is also used, which ensures the normal functionality of the gas trimmer string knives. This article will tell you about the prices for gasoline manual lawn mowers and trimmers, and it will also help you make the right purchase, which you will not regret.

There are two types of these mowers: amateur and professional models, designed to solve problems of a certain complexity. The first category includes models FS 38, FS 45, FS 55, etc. The features and differences of these tools are the motor power (from 0.9 to 1.2 hp depending on the configuration) and tank volume (approximately 0. 34 l).

Professional trimmers include Stihl FS 130 and FS 250. Let's look at the characteristics and properties using the example of several mowers, in particular FS 38, FS 70 and FS 130.

Watch the features of the device in the video.

Petrol lawn mower FS 38

The new generation engine reduces fuel consumption. The cost of this model varies, but the average price is about $300.

It features the latest high-power engine that does not emit large amounts of harmful emissions.

The price for the Stihl FS 130 mower is about $400.

• weight – 5.9 kg.

The range of prices for these models does not indicate any difference in quality; first of all, each Shtil mower is designed for a specific type of work.

It is clear that there is no point in purchasing a more expensive and powerful model if you have a small plot or front lawn. Simpler models will cope with this task perfectly, but the word “simplicity” is not used here in a derogatory manner. More powerful mowers are designed to handle larger areas with overgrown and dense surfaces, hence the price difference. If you are confused by such a variety of tools, then do not be upset, but feel free to click here and we will tell you how to choose a lawn mower for your dacha.

Recommendations for use

It is necessary to take temporary breaks from work. This is necessary to ensure that the device’s engine does not overheat and fail prematurely. For amateur models, a break is provided every 20 minutes for the same amount of time. For professional mowers, work must be interrupted every 50 minutes, in which case the downtime should be at least 10 minutes.

You need to monitor the condition of the fuel tank. If you do not plan to use the mower for a certain period of time, it is better to drain the remaining fuel from the tank compartment. This will help avoid damage to engine parts.

Bottom line

Many may be put off by the relatively high prices of Shtil products, but if you think about it, what is more important - reliability and good results or savings that come at the expense of quality? But, if you set out to save money, then we offer you the option of a do-it-yourself lawn mower; by assembling the device with your own efforts, you will know all the nuances and structure of the tool.

Of course, you can choose cheaper Chinese analogues, but then no one will be able to vouch for the result of the final work and for the service life, which can be very short for such models. So it is more profitable to purchase a mower once from a reputable company, which Shtil certainly is, and enjoy stable operation over many years of operation.

Problems and solutions - DIY repairs

But what to do if suddenly it was not possible to avoid a breakdown of the mechanism? We won’t go into the reasons for this, but it would be useful to consider possible problems that may arise with the mower, as well as methods for eliminating them on your own.

The engine does not start. If you encounter this problem, then you first need to assess the amount of fuel in the fuel tank; maybe there is no problem as such, but you just need to add fuel and continue working. By the way, the fuel used deserves special attention, because the service life and quality of operation of the lawn mower depend on its quality. Experts recommend AI-92 gasoline, no lower.

Stiga robotic lawn mowers are an innovation in the agricultural industry that have managed to win the hearts of many farmers and summer residents.

A homemade circular sawmill is easy and simple, thanks to the detailed instructions that you will find on this site.

If you asked yourself the question: “How to choose a professional saw without having experience working with this tool?”, then here you go //machinspec.com/lesozagotovitelnaya/benzopila/kak-vybrat.html.

Another likely cause of unstable engine operation may be a dirty fuel filter. You should carefully inspect it and clean it if necessary. If the filter cannot be repaired yourself, you should replace it with a new one.

Do not forget about the air filter, clogging of which can also lead to failure of the tool. In order to avoid this, the part is removed and washed in water with detergents, or in gasoline if there is no access to a water supply.

Then the filter must be thoroughly rinsed and dried, carefully monitoring the integrity of the structure. Before installing the part into the mower, it is necessary to lubricate it with a small amount of oil. However, if you don’t want to bother with cleaning the unit, then we suggest that you familiarize yourself with a lawn mower with a mulching function, because it will not only cut the lawn, but also prepare further fertilizer.

The spark plug can also affect engine performance. It is necessary to unscrew it and check the condition, if necessary, replace it with a new one.

If after all the manipulations done, the engine still does not start, then you can resort to the advice of experienced craftsmen who have used them in practice.

It is necessary to adjust the speed using the carburetor screw. The mower is placed in such a way that the fuel hits the bottom of the carburetor. To do this, place the tool so that there is an air filter on top.

Next, you need to remove it and pour some fuel into the carburetor, then install all the parts in place. The engine should start.

You can pull the starter handle while closing the carburetor choke. Next, open it and pull the starter a couple more times. This is a fairly universal method, proven over the years.

These tips are not a panacea, but they are quite effective and useful.

The mower stalls immediately after starting. The main cause of this problem is incorrect carburetor adjustment. It is quite simple to determine this problem - strong vibration will be felt when the mower is operating. You can fix the problem yourself by looking at the instructions, which describe the problem and solutions in detail.

Particular attention should be paid to the fuel channel; it is often the reason that the tool stalls. Check it regularly and clean it from dirt.

Various small parts, such as a cable or fuel pickup hose, can affect the stable operation of the tool. Therefore, you need to monitor their condition, check for cracks and small punctures.

Many may be put off by the relatively high prices of Shtil products, but if you think about it, what is more important - reliability and good results or savings that come at the expense of quality? But, if you set out to save money, then we offer you the option of a do-it-yourself lawn mower; by assembling the device with your own efforts, you will know all the nuances and structure of the tool.

Petrol mower Stihl FS 38 - problems and solutions

Good morning. Please help me figure out the fs 38 trimmer - I didn’t get it to work, namely the drive shaft does not turn the shank. When disassembling, there were 2 bushings and a drive shaft in the pipe; the shank was fixed on top with a bolt through the pipe. I read here about some kind of retaining ring. I understand that when I press the gas, the drive shaft flies out and does not turn the shank, help me figure it out

Kain81, It is necessary to replace the shank assembly, article number 4140-640-1402 costs 300-400 rubles, the lock washer will not help. Make sure there are no cracks on the rod where the shank is secured with a screw and do not forget to lubricate it before installation and every 25 hours of operation with BigMazzy gear lubricant, the gap is 0.1-0.3 mm from the flywheel magnets

That's it, I figured it out. The top part of the pipe was bent and was not inserted all the way and was not clamped with a screw. That's why the drive shaft was removed

Good morning! Experts, can you tell me what the problem is: gasoline has stopped flowing into the so-called “nipple” on the carburetor. Pressing does not lead to anything. The fuel filter is new, when you remove the top part of the carburetor and press the spring, gasoline flows. And most importantly: when you get into the carburetor, .k the trimmer only worked at idle, as soon as you pressed the gas it stalled immediately.

Dear forum users! Please help with the repair! I’ll start in order: I gave the trimmer to a neighbor to mow the grass on his lawn for a day. There was a full tank of gasoline. (He has his own gasoline) After 40 minutes he comes and says: “It works at idle, but when you give it gas it stalls.” It turned out that he filled in a mixture that contained 2 times more oil than needed (instead of 100ml-200ml). But this became clear later, and before that he got into the carburetor, disassembled it, screwed something up and now it’s gasoline it doesn’t flow into the nipple on the carburetor at all. Knowledgeable people, help, otherwise it’s a long way to get to the service station, and it’s unreasonably expensive there.

scham wrote: he reached into the carburetor, disassembled it, screwed something up and now no gasoline flows into the nipple on the carburetor at all.

I don't have a 38. But I'm trying to guess. I don’t know if the 38 has a filter in the tank, then a hose. Well, I don’t know in the carb itself, I didn’t climb into it.

The filter in the fuel tank is new.

scham, See hose. Is it pinched, or vice versa, is it damaged, maybe it is sucking air. Then it won't download either. If everything is fine, I’ll try to contact a specialist about the carb.

valerich, thank you! The hose is most likely also in order, because if you remove the nipple and the fuel pump, then gasoline flows. It seems to me that when he disassembled the carburetor, he could have damaged the gasket (there is a slight bend).

valerich wrote: I’ll try to contact a specialist about the carb.

Already applied. I think he will unsubscribe himself.

scham wrote: he reached into the carburetor, took it apart, screwed something up

Go, torture him, what exactly did you do with the carburetor - did you remove it, what covers did you open (if you did), which screws did you turn and how much? So, without this information, nothing can be said at all.

Yes, and be sure to check the exhaust pipe on the muffler to see if it is clogged with soot.

And in general, hand the scythe to your neighbor and let him call the service. After all, what kind of habit is it to take other people's things and poke around in them?

. If you take it and it doesn’t work properly, give it back and say it doesn’t work. In short, okay, let’s give the information and let’s think. I won’t croak for now, maybe everything will work out. I’ll check in periodically, even though I’m on a very weak Internet.

Olegych wrote: And in general - hand the scythe to your neighbor and let him go to the service. After all, what kind of habit is it to take other people's things and poke around in them?

.

Stopudovo agree. Did you climb? Now let him take it and repair it to the condition in which he took it.

Olegych wrote: And in general - hand the scythe to your neighbor and let him go to the service. After all, what kind of habit is it to take other people's things and poke around in them?

Yes, I would have done that, but the person helped many times in different situations, and so it wouldn’t be very nice on my part. He says that he removed the upper part, where the nipple, pump, gasket and membrane were. He turned the fuel supply screw, but then set it back as it was.

Well, any ideas?

The membrane and gasket may have been mixed up. Remove the top cover, lay out the parts in order, take pictures - we'll see.

Olegych I already checked, first the gasket, then the membrane. I think it only makes sense to take a picture of the gasket, since there is a small crease on it.

scham wrote: I already checked, first the gasket, then the membrane. I think it only makes sense to take a picture of the gasket, since there is a small crease on it.

It's all about the pump piston, it's located in the carburetor. You need to remove the throttle, carefully! The piston will fly out, remove the spring. Lubricate the piston with an autolock and not seat it all the way so that the piston does not interfere with the movement of the throttle shaft. plant it deep and close the channels.

I'm sorry that no one could help you)) this is my first time on the forum)))

scham, if you have any questions about the order of carburetor assembly or adjustment, write! I'll answer)))

scham wrote: It turned out that he poured in a mixture that contained 2 times more oil than needed

This is not a problem, the problem may still be in the quality of the fuel itself. What kind of gasoline, oil? How many days has it been active (how many days have passed since the fuel was prepared)? People, always use fresh fuel! When oil gets into gasoline, a chemical reaction occurs (decomposition of oil in gasoline) and the survivability of the fuel depends on external factors.

scham, damn it) also check the muffler before doing this. Maybe it's clogged? "> - if anything happens, knock!

Uncle Syoma, tell me what gap should be between the rotor and the stater?

Post #126. “It works at idle, but when you give it gas it stalls.”

Same problem. If, with the throttle fully open, you manage to spray something like Car Cleaner (engine cleaner) into the drawbar, it screams at full blast! Even WD 40 works. It is clear that there is not enough fuel for full power. By analogy with the autocarb, the main dosing system does not work. I think that's what it's called. I’m a complete ignoramus about this thing, but I’d like to figure it out! My engine has been sitting idle since 07/2013 - something must have turned sour.

The fuel is fresh, just from the pump. The oil is correct and 1:50. The muffler is dry and clean. Start in 1-2 attempts.

Thanks for the hint - how to fix the problem, but - where and how is this piston, throttle, etc.

That. questions are ripe:

1. Where can I get acquainted with the theory of this carb? Description, operating principle of its systems.
2. Where can I get my hands on an explosion diagram of this carb (well, at least similar)?
3. Possible faults and solutions?

I would be very grateful for any information: literature, links, videos, etc.
