How to assemble the body of the Stihl lawn mower. Review

complex reasons for the refusal of the lawn mower

If the step-by-step algorithm for searching for a malfunction has not given a result, and your braid for grass still does not start or stalls, it is worth examining the carburetor and the engine itself. A clogged carburetor can become one of the reasons, unstable operation of the tool. Three main problems can be distinguished here:

• Clogging of channels or nozzles. All this is cleaned with special flushing or blown by a powerful stream of compressed air from the compressor. Do not use needles and wire, so the passing sections can be damaged;
• Wear of the carburetor laying. Output. replacing the failed laying
• Violation of tightness. To verify this indicator, you can use the usual household tonometer, replacing the suitable manometer on it. Follow the testimony: if they do not change, everything is fine, and since the pressure will begin to fall, then some part of the carburetor is faulty. Will have to find it and replace it with a new.

If everything is in order with the carburetor, then the gasoline trimmer for the grass may not be launched due to wear of the piston group. If chips are detected, scratches or backbone on the piston or cylinder, they should be replaced. Piston rings are subject to mandatory verification. A small rally piston when swaying a connecting rod indicates that it was time to change the rings. This procedure is best entrusted to the specialists of the service center.

Diagnosis of the filters of the lawn mower

Another prerequisite for which a gasoline braid for grass stalls is a 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 blowing and carefully cleans 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.

We diagnose a candle and a candle channel

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle can become a prerequisite. Here, a regular candle key is suitable for repair (every motorist probably has a spare candle.

• We twist the candle and wipe;
• We dry it thoroughly (you are not worth it)
• Excess fuel in the chamber we drain through the candle hole and dry it;
• We clean the old candle from soot with the help of a file or a ladies’ file;
• We set a gap with a distance of 1 mm (you can check with any coin)
• Returning everything to place and try to start a trimmer for the grass.

Dries the channel, you need not for 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.

If the operating 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 the grass does not start, it is necessary to exclude such a reason as the lack of spark due to weak contact between candles and a high-voltage wire. 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.

Remove the spoiled part of the bearing

With an increase in loads in operation, the lawn mowers occur problems with the device knife. It does not rotate, or even a stop is coming. A strong screech and noise are heard during this. These signs indicate that it is required to change the damaged bearing.

The bearing is often destroyed due to the fact that the lubricant is used poor-quality, or it is not at all. Difficult conditions for using a trimmer for grass also contribute to the rapid failure of the bearing. We are talking about when a gasoline braid for grass is used where there are small wood thickets. Various particles, both small and large ones in this case can violate the integrity in the anthers.

To get to the bearing and remove it, you will have to disassemble the gearbox. After that, use a special puller to remove a spoiled bearing. If this is not possible, a hammer and an instruction will come in handy.

Try to work carefully, do not allow impaired integrity in the seating. Do not heat the part before starting the repair, so you risk changing operation characteristics.

Preparatory stage

Repair of any equipment should begin with the stage of preparatory work, and the STIHL 180 saw is no exception. At the preparatory stage, before disassembling the Stihl 180 chainsaw is carried out, it is necessary to remove the side cover, chain and tire from the chainsaw. Further, using a compressor and brushes, you need to clean the chainsaw of dirt, sawdust, oil drones and other things.

Particular attention when cleaning the saw should be given to the place where the leading star of the chainsaw is located, t. to. This is the most polluted site.

In places of large accumulation of oil, you can rinse with clean gasoline.

Factory parameters of the model

STIHL benzo.coser in this configuration is released by solid factory parameters.

Technical characteristics of a trimmer for grass include:

• The volume of the standard ICE cylinder is 27.2 cm3;
• The power of the standard motor is 0.9 liters. With.;
• The capacity of the tank for refueling by the fuel mixture is 330 ml;
• fuel consumption when working under high loads. 320 ml/h;
• The maximum possible diameter of mowing when using fishing line is 38 cm;
• cut diameter when using a knife. 25.5 cm;
• maximum sound pressure when working with a metal knife. 109 dB.

STIHL FS 38 Trimmer has small dimensions and low weight. The mass of the model in the finished form is 4.1 kg, and the length without cutting equipment is 147 cm.

Common malfunctions of carburetors

Damage of the carburetor of the trimmer for grass occurs due to the use of poor quality gasoline, damaged air filter and the accumulation of dirt in the chamber of this block. Most often, it is quite possible to repair a carburetor with your own hands. Below listed typical malfunctions of the carburetor motorcosa.

Problems of the fuel pump

A common malfunction that “pursues” the fuel pump is a deformation of the pump membrane. For this reason, it does not fit properly, and the pumping canals are not compacted.

The reasons for the deformation of the membrane can be as follows:

Possible breakdowns

Unfortunately, even competent and careful operation of high.quality gasoline lawn mowers does not completely exclude the risk of breakdowns. Consider the most common problems.

• The engine does not start. Perhaps the candle failed or the fuel does not enter the carburetor.
• Unstable work ICE at idle. One of the most common reasons in such situations is the wrong setting of the carburetor.
• The trimmer for the grass does not develop speed and does not provide sufficient power. Such phenomena are associated with the need to clean or replace the air filter, candles, as well as adjusting the carburetor and removal of soil in a muffler.
• Overheating of the engine, which can be caused by the use of low.quality fuel mixture.

Quite often, the owners of gasoline mowers have to face situations when they stall when pressed on gas. The most common reason in this case is the incorrect operation of the carburetor requiring adjustment. Most often this happens after a long.term storage of the device or as a result of its operation in difficult conditions.

When the gas is added, the fuel valve can be closed to the engine stop, which will need to be slightly weakened to resume the normal supply of gasoline. Often you have to face clogging of the saapun, that is, a check valve located in the fuel tank. Among other things, the reasons for the fact that the ICE of the trimmer for grass stalls, the cable sagging in the carburetor and stretching of the fuel hose can be sagging.

Adjustment of the carburetor lawn mower Stihl FS 55

Adjustment of the carburetor lawn mower Stihl

FS 55 Sadservice Sadservice Sadservice Spare parts.com.ua.

A combustible pump (its membrane) is sucked into the carburetor system. Carburetor Motokosi then passes through a fitting in a carburetor. Then the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. On the needle valve moves into the membrane chamber.

• Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
• The fuel supply system is certainly narrowed by the mixer to accelerate the flow.
• Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already small. Thanks to the pressure drop, fuel seeps through a jickler.
• Acceleration of the air flow contributes to the transfer of fuel (gasoline) and its spray. Ultimately, a fuel mixture of the desired proportion or density appears.
• The air-fuel mixture penetrates the motor cylinder through the fuel tube.

Read Stihl 250 Carburetor adjustment video

The level of air density in the system depends on the area of ​​the open air damper. The more extensive the damper is open, the greater the fuel consumption and power.

Simply put, adjusting the carburetor on a benzocos. creating a good fuel consistency due to the correct air supply.

How to adjust a carburetor on a gas tank

Before adjustment, you need to painlessly clean the filters according to maintenance in the annotation.

The upcoming setting of the carburetor of the lawn mower with your own hands is made by adjusting screws. There are three of them:

Right (l). adjustment of the fuel consistency for low revolutions.

It is necessary to find the highest speed at idle. To do this, leisurely twist the screw (l) on the right and on the left.

For adjustment, the screw is rotated by a quarter of turnover by all means counterclockwise.

Lower (t). is responsible for adjusting the motor at idle.

For proper adjustment specifically, the idle move is typical:

• sustainable work of a cool motor;
• not high speeds of a hot motor;
• for a trimmer head, there is a lot of revolutions;
• Sustainable work of the motor when changing the position (sharp rise or descent of the knife).

Read Carburetor Adjustment to 45 Motoboglok Agro

Left (H). adjustment of consistency at high speeds. (The screw is set up last).

The overall adjustment of the highest revolutions, the power of the motor, temperature and gas consumption depends on the left screw (H).

Setting a carburetor of a lawn mower with the last screw is carried out as follows:

• Open the throttle to the full, at the same time give out full gas. Turn the screw clock until the time until the speeds fall (in this case, they are oriented by ear).
• Turn the screw as slowly as possible against the hourly to the uneven operation of the motor.
• Then turn back at all, hearing a little measured, even work.
• For a more pleasant implementation of abilities, it is more convenient to discern the work of the most experienced user:

It is curious that based on the beliefs of the creator of the video, the configuration (its correctness) is determined by the color of the candle, and not just by the turnover and stability of the motor.

True tuning the carburetor with your own hands in this case-combustion of the fuel consistency without a residue, the color of the candle should be light brown.

Quick launch of the lawn mower: tips

Some pull the pen with such force that it is necessary to repair the starter of the lawn mowed with their own hands. This is possible only in the case of a gust of a cable or breakdown of the cable handle. In other cases, it is recommended to replace the starter. This node is sold in the collection.

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.

In 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 implementation of various components for washing and steam machines. It all began, like many companies, with a small production and narrow orientation, which made it possible to focus on the quality of the manufactured products.

In the early 30s, the first Stihl chainsaw was released, characterized by convenience and functionality already at that time. The company is developing at a long time, constantly introduce new tools, which gives it the opportunity to enter the international market. And already in 1931, the first regular supplies of products were organized at the moment, the company has launched its activities in more than 160 countries of the world, opening new centers and production departments in Switzerland, China and many other states. This is understandable, because the assortment of the company is impressive: motoburs, gasoline sprayers, mowers, gasoline trimmers for grass, chainsaws and much more. I would like to note that Shtil chainsaws are very popular due to their functionality and acceptable price.

Technical characteristics of a trimmer for grass

In addition to the good quality of the assembly, the Stihl FS 38 lawn mower is highlighted by worthy factory parameters.

The list of the most important characteristics of the garden tool includes:

• Power of the factory ICE. 0.9 liters. With. at 9500 rpm;
• tank for refueling the fuel mixture. 330 ml;
• maximum fuel consumption. 320 ml/h;
• Coverage when mowing with a fishing line/knife. 38/25.5 cm;
• sound effect on the operator. 97 dB;
• Weight. 4.2 kg.

STIHL trimmer differs from analogues with modest dimensions. The length of the motorcycles is 147 cm with dismantled cutting equipment.

How to replace the spark plug correctly?

As you can see, there is nothing superplousing in this procedure.

A new spark plug for a two.stroke internal combustion engine of a gasoline braid for grass is installed in return for the old detail that failed

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:

What are the breakdowns in the gas tanker?

Problems in the transmission associated with the lack of lubrication in the bearing.

In this model of gasoline braids for grass, the transmission is represented by a flexible shaft, which is located in the bar, the upper clutch cup, the bearing housing from below. We carefully analyze all these nodes.

The bearing on the lower case transfers rotation to the spool through a flexible shaft, starting from the bowl from above. All this is not too difficult to construct, but take care of timely maintenance.

The biggest problem is the lack of lubricant in the middle of the bearing building, namely in the sleeve. The result is sad. the duration of the operation of the bearing is reduced several times. The procedure is quite simple, it is easy to make it yourself, at home.

Repair of a flexible shaft, which transfers rotation to a spool from an electric motor, in principle, is impossible. When damage, you will only have to replace the broken part. The shank in a flexible shaft is triggered if you encounter stump or stone during work. When you remove the bearing case, take out the spoiled shaft and make a replacement.

The clutch cup is transmitting movement to a flexible shaft from the coupling. Natural wear occurs, and the seat is as if licking. Sometimes this can happen due to the fact that during the use of an electric gasoline braid for grass, you got to extraneous objects.

To replace the bowl in the clutch, disassemble the entire trimmer case for the grass:

A plastic crankcase is screwed by many screws. Unscrew them all. A few pieces have a different length, remember where they were.

The screws with which the engine is attached to the plastic case also have some differences from other mounts. Inside, on a hat, there is an engraving.

Next, remove the top from the crankcase, remove the terminals on the ignition module. Make a note where the terminal sits on top of the module. This will come in handy when you collect everything back to avoid confusion.

The cylinder piston needs to be blocked with a stopper. There is a screw in the clutch cup. When you twist it, you can easily remove the bowl itself.

If you find damage, replace the new part.

How to repair a trimmer to grass. master class

A cap of dust protection was rubbed from the case of the clamping nut and the boot itself fell out. Schools are clogged with grass and earth. The unmuffling and the wire of the bobbin does not help manually.

There are no such small and desired spare parts in the city stores. There is a wearable head assembly Autocut from 5-2 for 900. The price is prohibitive.
