Petrol mower Shtil FS38. Description of the model. Features of operation, maintenance

The STIHL FS 38 trimmer is probably well known to all fans of high-quality garden equipment. People who have once tested a brand's products in practice rarely switch to products of other brands, because German quality conquers completely and completely.

This lightweight gasoline device is quite compact, it is ideal for cleaning a small garden area. Many owners of private sectors prefer this “assistant”, because it copes with its task perfectly and demonstrates a high level of performance.

Two-stroke engine with a power of 0.9 liters. With. will be able to withstand heavy loads, and the AutoCut mowing head will cope even with relatively tall bushes and weeds. The D-shaped handle easily adapts to the height of the operator, so the new owner will be able to adapt the unit completely to suit themselves.

Since the engine displacement is 27.2 cm 3, the Stihl FS 38 trimmer can reach quite high speeds. The presence of a special quick start system eliminates the need to start the unit several times in a row, because it will start working on the first try.

Specifications and Features

• Cutting width: 23 cm;
• Fuel tank capacity: 0.33 l;
• Weight: 4.1 kg;
• Rod: curved;
• Line thickness: 2 mm.

Thanks to the manual fuel pump, a person can easily pump fuel into the carburetor. This point is especially important in a situation where the lawn mower has been idle for a long time. Constantly adding fuel will allow you to quickly start the device even after a “long vacation”.

Along with the unit, the owner receives protective glasses and a mowing head. You can understand the assembly features and other specific aspects of operation thanks to the manual presented on our website.

For other useful information, please see the following document:

The curved shaft of the STIHL FS 38 lawn mower with a rounded handle is worthy of considerable attention. Thanks to this design, the device can easily cope with cleaning areas even in narrow or limited spaces.

All controls are located on a convenient handle, so you don’t need to spend a lot of time looking for where and what to switch. During operation, such a moment is very important, because the operator can not be distracted and adjust the operation of the machine without unnecessary movements.

Elimination methods

The list of upcoming work on the engine may be as follows:

• replacing the fuel pump;
• disassembling and washing the strainer;
• replacing the adjustment lever;
• it is also necessary to clean the adjustment space;
• replacing the membrane (or the entire block where this membrane is located);
• adjusting intake, exhaust and needle valves;
• replacing dampers;
• cleaning fuel channels and diffuser;
• replacing screw springs;
• change of primer.

Not all of these jobs can be completed. It often turns out that many of them are not needed if a specific malfunction is immediately detected.

Adjusting the carburetor of the Stihl FS 38 lawn mower

• First you need to stop the engine;
• Then install the mowing head;
• The next step is to check the air filter, and if the filter element is not in good condition, it should be replaced;
• You need to turn the idle speed adjustment bolt completely clockwise until it stops, and then 1.5 turns counterclockwise;
• After starting the device, you should wait until the engine warms up;
• Using the idle stop bolt, the owner must adjust the idle speed in such a way as to immobilize the cutting tool.

It’s not difficult to understand all the procedures, the main thing is to take the matter seriously and get ready to work. Moreover, many owners note that you can not only adjust the carburetor yourself, but also replace spare parts. The diagrams below will be excellent helpers in this matter.

Device design

The essence of the device's operation is to transmit torque from a power drive - gasoline, electric or battery - to a cutting tool - a knife or fishing line. The transmission mechanism is a shaft located inside the rod. In devices with a curved shaft, its role is played by a steel cable.

The rod is attached to the drive gearbox - two- or four-stroke. When turned on, torque is transmitted through the shaft to the fishing line or knife.

The most complex part of the device is the motor. Damage to the shaft, belts, and cutting tools are classified as mechanical failures, but repairing the engine of a lawn mower usually causes difficulties. Some problems associated with contamination of engine components can be eliminated yourself. It is better to entrust replacement of spare parts or adjustments to a specialist.

Pros and cons of the model:

• Excellent performance;
• Compactness;
• Light weight;
• Functionality;
• Endurance;
• Ability to independently adjust the operation of elements;
• Availability of a manual fuel pump;
• D-handle, etc.

Naturally, the list of positive aspects should include the reliability of the brand itself.

• The need to constantly check the fuel level;
• Small motor resource;
• Low power;
• Expensive;
• Poor equipment.

The presence of not particularly catastrophic shortcomings of the model does not have a negative impact on the popularity of the unit, because ideal technology simply does not exist.

Adjusting and repairing the carburetor of a lawn mower

The trimmer is not a complex household appliance, which is why most of its breakdowns are mechanical in nature and can be quite successfully fixed with your own hands. Even if the engine fails for serious reasons - damage to the piston ring, for example, repairs come down to replacing the part.

And even with a relatively simple design, such a part of the device as the carburetor needs adjustment.

Comparison with other brands

Today, many companies produce gasoline trimmers. Taking into account the cost of such equipment, the choice of specific models should be approached with maximum attention. Nowadays, almost all developers of specialized tools and small construction equipment are engaged in the production of gasoline scythes. We are talking about both industry leaders and little-known companies.

The following brands occupy the first positions in the current popularity ratings:

Naturally, it is impossible to definitively answer the question of which brand and model is better. This is due to the presence of a whole list of selection criteria. However, when purchasing a lawn mower, in order to identify the competitive advantages of a particular brand, you should compare the performance indicators of representatives of different model ranges.

Most often, Stihl products are compared to trimmers from the Echo, Husqvarna and Makita brands. Initially, it should be noted that these models of equipment belong to the same class and have largely identical technical characteristics, with the exception of some nuances.

This primarily concerns the designs of trimmers equipped with so-called bicycle-type handles. All scythes can be equipped with two types of cutting elements: fishing line and discs.

Every Stihl lawn mower is equipped with a quick start system. Among other things, these devices, like the models of the mentioned brands, have a belt that effectively reduces the load on the user’s hands. According to reviews from owners, trimmers from the famous Makita brand have the most advantages. We are talking here about an increased rotation speed of the cutting elements, which ensures appropriate performance.

Principle of operation

Carburetor

– a power system module in which liquid fuel and air are mixed before being supplied to the engine cylinders.
Gasoline lawnmower adjustment
. Depending on the tool and its operating mode, mixing and feeding are adjusted accordingly.

The design of a lawn mower carburetor is the same in almost all cases. Adjusting the carburetor of a Chinese brush cutter. It belongs to the category of float devices. The latter provide constant characteristics of the finished mixtures.

The mechanism of operation of the module is as follows.

• Air enters the body of the tube with an air damper. Lawn mower matrix carburetor adjustment. The latter increases or decreases the air flow depending on its own position.
• In the area where the hole for supplying gasoline is formed, the tube has a narrowing - a diffuser. Here the flow speed increases.
• Fuel is supplied from the float chamber through a nozzle into the tube. The float level determines the volume of fuel supplied. Because the pressure in the chamber is normal, but in the tube it is low due to the greater rarefaction of the air, gasoline is sucked in through the nozzle.
• The accelerated air flow picks up the fuel and atomizes it, forming an air-fuel mixture of suitable density.
• The mixture is sucked into the cylinder through a pipeline.

The more open the air damper in the tube, the higher the air flow density, which means more fuel enters the cylinder. Stiga brush cutter adjustable handle. Setting up the carburetor of a lawn mower comes down to setting the valve ratio at which the density of the fuel consistency becomes good.

Instructions for users

Any gasoline tool requires a preliminary run-in before use. At this time, the moving parts are ground in to reduce resistance. Since this stage occurs at low speeds, it is easier for a beginner to master such equipment.

Before starting work, you should prepare the mixture. Its parameters and materials used are indicated in the technical documentation for the product. It looks something like this: 2.5 liters of 95 gasoline are mixed with 100 grams of Stihl oil from a red package. This procedure must be carried out in a container that is resistant to aggressive liquids. A simple metal canister will not work due to rusty areas that cannot be detected inside. Corrosive particles entering the carburetor clog it, which leads to failure of the part.

During the warranty period, the lawn mower requires servicing and carburetor adjustment. It is recommended to do this at an authorized technical center.

Signs of imbalance

Debugging of the carburetor is certainly done during the manufacture of the device. Petrol mower Texas 330 carburetor adjustment. Usually, owners will find out about the need to adjust the fuel supply with their own hands only after quite severe breakdowns, during the process of correcting which the module was removed and, for example, cleaned.

Signs of a failure in the settings are the following:

• it starts, but then the engine stalls - since the engine can only work when a certain amount of gasoline is supplied, if the fuel is very “poor”, in other words, the supply channel is blocked, the engine will stop;
• very high fuel consumption, a lot of exhaust gases - the result of incomplete combustion of the mixture. In this case, on the contrary, there is a lot of fuel and the mixture is extremely dense.

STIHL FS 55 - carburetor adjustment (idle speed)

Adjusting the carburetor trimmer Shtil FS

55 in the video we perform in order to adjust the idle speed.

The carburetor of Stihl, Makita, Husqvarna and other lawn mowers is adjusted using adjusting screws. Sometimes the prerequisite for malfunction is a violation of fixation - due to vibration or damage to the protective cap. Such a breakdown can be found by simply trying to slightly turn the screw: if the fixation is not tight, it is worth checking the setting.

Do-it-yourself trimmer carburetor adjustment

Setting up the module is not a repair and replacement of spare parts is not required. In this case, the lawn mower carburetor repair kit will not be useful.

There are three screws for debugging:

• L – is regulated first, because it is responsible for the supply of fuel at low speeds;
• H – it is responsible for the supply of gasoline at high speeds, also for fuel consumption and temperature;
• T – it is used to debug the idle speed.

There are options, usually the carburetor of a Chinese lawn mower, when only one screw remains on the body for debugging - for the idle speed option. Adjusting valves on a lawn mower. This does not mean that the module is configured automatically - it means that even such a type of repair as debugging will be problematic. The photo shows the adjustment of the carburetor of a Chinese lawn mower.

1. The module is configured only when the engine is warm: for this, the device is turned on for 10 minutes beforehand. Carburetor adjustment Japanese trimmer. Brushcutter trimmer ignition adjustment. If the mowing head rotates at idle, then debugging begins immediately: turn the screw T counterclockwise
   until the rotation stops.
2. The adjustment begins with screw L. The screw is turned to the right and to the left until a position is found at which the idle speed does not become the highest.
3. Then the screw is turned ¼ turn counterclockwise. This will be his working position.
4. The idle speed must be adjusted by turning counterclockwise to increase the speed and clockwise to decrease it. Its debugging consists in achieving a mode in which a sufficient number of revolutions are made before the mowing head begins to rotate. Gasoline self-propelled lawn mowers speed control. With all this, the engine must operate stably in different positions.
5. The position of screw L is determined last - at maximum speed the trimmer should not operate for more than 10 seconds. The throttle opens, the screw turns clockwise, very slowly, until a decrease in the number of revolutions is heard by ear.
6. Then the screw also slowly turns counterclockwise until the motor begins to malfunction. After this, the screw is turned back clockwise until the engine starts working normally again.

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.

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.”

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.

I’ll share the diagrams, but I don’t know how to “stuff the stuff into caramels”

As far as I know. This type of equipment uses carburetors of the walbro type (or ZAMA, the same type). There are plenty of diagrams and descriptions of walbro on the internet.

Starting the engine

The engine is started at a distance of 3 m or more from the place where the device is refueled. This work cannot be carried out indoors. Before you need to take a stable, reliable position. At the same time, the motorcycle device is held very tightly. The cutting tool should not come into contact with the ground or objects, because it may spin when started.

The unit is serviced by only one person; however, there should be no third parties in the area with a radius of up to 15 m. Otherwise, you may be injured by thrown objects. Starting the engine of the STIHL FS 55 lawn mower, the properties of which are presented in the article, should not be started by hand. After releasing the gas lever, the cutting tool will move for some time by inertia. Flammable materials should be kept away from the hot flow of gases and the surface of the hot muffler, because this may cause a fire.

Clogging of the adjustment space

Deposits may accumulate in the adjustment compartment. The needle does not close the hole completely, and a lot of gasoline enters the fuel chamber - the engine overflows it, possibly flooding the spark plugs. Because of this, the gasoline-air mixture contains an increased amount of gasoline vapor. The efficiency drops noticeably.

Inlet needle is damaged

The inlet needle breaks due to the presence of metal and stone particles in gasoline. As a result, the intake needle seat does not fit tightly to it, and the fuel mixture flows. There is too much air in the combustible mixture created by the carburetor, which can cause the engine to “sneeze” during operation. Finally, the needle may become stuck due to low-quality gasoline, or the unit has been idle for a long time.

Checking the correct settings of the Husqvarna carburetor

The engine revs quickly, smoothly and confidently, and revs a little at maximum speed; the T-35 trim head should not rotate at idle.

Intake control lever sticks

Sticking of the adjustment lever is a consequence of its incorrect installation or accidental bending. The contacting edge will be in the wrong position. This will disrupt the additional injection of gasoline.

They are represented by the following models: the German gas trimmer FUBAG FPT 52 38712 and the Russian Sturm BT8952D, which have similar characteristics and fall in the same price range.

Victor

I purchased this trimmer model last year to tidy up my garden. I've only used it a few times myself, mostly my wife works with it. She copes with the weight and hasn’t complained yet. He says it’s convenient to work. Based on my feelings, I can say that it is very light and comfortable; if it had a belt, it would not be worth the price. Excellent for trimming trees and shrubs. In my opinion, it is not suitable for mowing in large volumes, as my hands get tired. Otherwise, there were no problems with the brush cutter, everything works great and does not fail.

Gennady

I have been using this trimmer model for 2 seasons in a row. I mainly use it for mowing hard-to-reach areas after going through the lawnmower. Since she can’t get close to trees and fences, I use a trimmer. I like this tool. Starts first time, even in cool weather. To do this, you just need to pump up the fuel a little. And it’s also very easy to change the line in it, there is a special provision for this.

Paul

I was prompted to buy a trimmer by my neighbor’s constantly neatly trimmed lawn). I arrive at the dacha, see his lawn and want to bring the same order to my own. That's why I bought it. Now everything in my summer cottage has also become neat and clean. The control of the trimmer suits me quite well. Doesn't use much fuel. It just makes a lot of noise, but in my opinion they are all so loud. If we start mowing together with a neighbor, it creates such a symphony that the whole neighborhood can hear it. I definitely recommend purchasing it.

• Thanks to the AutoCut C5-2 mowing set, the cutting diameter is 380 mm.
• An ergonomic shoulder strap allows you to hold the Stihl lawn mower on your shoulder and rationally coordinate movements during operation.
• Light weight (4.1 kg), small dimensions, rational basic equipment - thanks to these characteristics, the STIHL 38 lawn mower is extremely comfortable to use.

Possible breakdowns

Unfortunately, even competent and careful operation of high-quality gasoline lawn mowers does not completely eliminate the risk of breakdowns. Let's look at the most common problems.

• The engine does not start. The spark plug may have failed or there may be no fuel flowing into the carburetor.
• Unstable operation of the internal combustion engine at idle. One of the most common causes in such situations is incorrect carburetor adjustment.
• The trimmer does not develop speed and does not provide sufficient power. Such phenomena are associated with the need to clean or replace the air filter, spark plug, as well as adjust the carburetor and remove carbon deposits in the muffler.
• Engine overheating, which can be caused by using a poor-quality fuel mixture.

Quite often, owners of gasoline mowers have to deal with situations where they stall when pressing the gas. The most common reason in this case is improper operation of the carburetor, which requires adjustment. Most often this happens after long-term storage of the device or as a result of its operation in difficult conditions.

The engine stopping when adding gas can be caused by a clogged fuel valve, which will need to be loosened slightly to resume normal gasoline flow. Often you have to deal with a clogged breather, that is, a check valve located in the fuel tank. Among other things, the reasons why the trimmer's internal combustion engine stalls can be sagging cable in the carburetor and stretching of the fuel hose.

Features of operation

Each Stihl lawn mower is designed strictly to perform the intended work, taking into account engine power. The manufacturer categorically does not recommend retrofitting or in any way improving the scythe device. Therefore, before buying a STIHL lawn mower, you need to clearly determine the scope of work ahead.

It is completely inappropriate to purchase a powerful trimmer for periodic mowing of grass on the lawn; light gasoline or electric models of mowers are quite sufficient for this.

During operation it is important:

• Follow the regime: work/rest at intervals of 20 minutes.
• Use high-quality gasoline not lower than AI-92.
• To prepare the fuel mixture, use original STIHL engine oil (50:1).
• When running the engine until 2-3 full fillings of the fuel tank, do not allow operation at maximum load.
• When storing the scythe for the winter or an expected break in operation, in order to avoid engine breakdowns, be sure to drain the remaining gasoline from the fuel tank.
• To ensure stable operation, systematically check the condition of the fuel filter - clean it or replace it with a new one.
• To prevent serious problems, it is necessary to avoid clogging the air filter.
• Follow safety requirements when operating STIHL lawn mowers.

Strict adherence to the requirements of the operating instructions is the key to long-lasting and trouble-free operation of the Shtil lawn mower.

Operating instructions for STIHL FS38 brush cutters

Tips for choosing

According to current statistics, it is gasoline models of mowers that are in greatest demand. This is largely due to their mobility and functionality. However, when choosing a specific piece of equipment, it is necessary to take into account a number of other parameters. In such situations, it would be useful to compare brush cutters with other types of trimmers.

Electrical devices are connected to a household network with a voltage of 220 V. Such machines do not pollute the air due to the absence of exhaust gases. No less important points will be the minimum noise level and relatively low weight. At the same time, the treated area is significantly limited by the length of the carriers used.

Cordless models are the least common grass trimmers available today. The electric motor of such mowers is powered not from the mains, but from the battery, which ensures maximum mobility. However, the operating time of the equipment is limited by the battery charge and averages 35-45 minutes. Another important point is the relatively high cost of battery models.

When choosing a specific model of a gasoline trimmer, you need to take into account its technical characteristics. Thus, low-power devices are equipped with reels of fishing line

On more resourceful and powerful models, knives and cutters can be used as cutting elements.

Advantages and disadvantages of the model

To mechanize the work of mowing grass on a small area, the Shtil FS38 lawn mower is ideally suited. Cleanliness and accuracy of the cut, mobility, lightness and high productivity are huge advantages compared to a manual scythe.

Among the malfunctions, owners often note that immediately after starting the STIHL lawn mower, it may simply stall. In this case, you need to check the fuel channel for clogging. Another reason may be improper carburetor adjustment, which can easily be corrected in accordance with service recommendations.

The price of the Shtil FS38 lawn mower is about 9 thousand rubles. Of course, you can buy cheaper, often short-lived analogues on the market.
