STIHL Benzotrimmer’s head does not spin. If the string is not served

trimmer for grass gasoline stihl does not spin the head

For each model of a trimmer for STIHL grass in the factory operating instructions, information about the device, principles and features of the unit is presented in detail. Clear adherence to the recommendations of the manufacturer significantly extends the service life of manual mowers.

Lawn mowers Stihl

• STIHL motorcosa consumes a fuel mixture of AI-92 brand gasoline and stihl motor oil for two-stroke engines in a ratio of 50: 1.
• There are several brands of corporate oil, Stihl HP Ultra is considered the best. In the case of use of non.original motor oil, the fuel mixture is prepared in a ratio of 25: 1.

• The prepared mixture should not be stored for a long time (no more than 1 month), unlike the original fuel mixture of Stihl Motomix, which saves its properties up to 2 years.
• STIHL plastic lubricant is used for lubrication of transmission, control is performed every 100 hours of operation. Air filter is usually changed annually.
• Sharpening of a metal cutting tool is performed as necessary, usually a few sawing movements are enough.

STIHL electrocos

During the operation of electrocosyles, there are no problems with fuel, however, specific precautions must be observed when working with the power tool. A special cable fixer prevents the unexpected disconnection of the STIHL electritrimmer from the network

Battery motor skots

STIHL battery motor.cakes, depending on the equipment of the model, provide different operating mode without recharging. from 12 minutes (FSA 45 model) to 420 minutes (FSA 130 model). Mowers are produced in different configurations: with a 36 V battery and a charger and without the indicated equipment.

The recharge time depends on the volume of the battery and the type of charger. A special fast.loading device Al 300 charges the AP 160 battery in just 25 minutes, which ensures uninterrupted operation of the Stihl FSA 65 battery motorcycles for about 1 hour.

At high speeds

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• problems with the circulation of the fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

, based on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

The main malfunctions of gasoline and electric trimmers

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen in the engine area.

Damage of gasoline trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:

• engine breakdown;
• problems with the carburetor;
• problems with the supply of fuel;
• muffler malfunction;
• gearal breakdown;
• The starter broke;
• Air filter problems;
• Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

It should be noted that the elimination of some of them is best entrusted to the specialist.

Basically, the trimmer for the grass ceases to work normally in the following cases:

• Electric cable malfunction;
• The control button is faulty;
• burned engine winding;
• Contact joints break on the engine.

Removing the handle

Direct disassembly of the STIHL 180, begins with the removal of the handle, which is attached to the chainsaw housing using three rubber shock absorbers. To remove, it is necessary to remove the plastic plugs from the inner cavity of shock absorbers, after which with the help of a powerful screwdriver, squeeze the upper shock absorber first, then the one which is closer to the posterior handle.

A gas trigger is installed in the back of the handle, which is connected to the carburetor through the wire traction in order to disconnect the thrust from the gas trigger, it is necessary to unwind two screws and disassemble the handle.

When the handle remains on one shock absorber, it is necessary to turn the chainsaw housing from the inside of the handle and breaking to the side, remove the case from the last elastic band.

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.

The flywheel of the Stihl 180 chainsaw is twisted with great effort, so to remove it, you will need a head with a metal gorge. The nut holding the flywheel is unscrewed by the head by 13.

To block the crankshaft from turning, you need to unscrew the candle and install the piston lock through the candle hole, if not, you can use the old lace from the starter, with nodes imposed on it and immersed in the cylinder through the candle hole.

It is strictly forbidden to hold the flywheel from turning by installing between its ribs and the body of the power screwdriver and other tools, with this method of blocking from turning, the flywheel blades are not able to withstand the loads and break off.

Repair trimmer for STIHL grass with STIHL FS 38

When operating the stihl benzotrimmer

Sometimes a cutting head breaks, it happens that a cable breaks.Repair.

After the piston in the cylinder is blocked, you can unscrew the nut of the flywheel. The thread in the nut is common, so you need to twist to the left side. Having loosened the nut, it is not necessary to remove it to the end, it is enough to twist it until the moment when its upper edge is equal to the tip of the shaft, after which the gap made of soft metal is installed on the nut and a sharp blow is made on it. Thus, the flywheel from a sharp blow jumps off the shaft and can easily be removed without the help of additional tools.

Pros and cons of the model:

Naturally, the list of positive points should be classified by the brand itself.

• The need to constantly check the fuel level;
• Small motorcycle resource;
• Low power;
• High cost;
• Scanty set.

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

Instructions for users

Any gasoline tool before starting use needs preliminary running.in. At this time, mobile parts are laid to reduce resistance. Since this stage takes place 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 approximately in this way: 2.5 liters of 95th gasoline are mixed with 100 grams of STIHL oil from red packaging. This procedure should be carried out in a container resistant to aggressive fluids. A simple metal canister is not suitable due to rusty areas that cannot be detected inside. Corrosive particles, falling into the carburetor, score it, which leads to the failure of the details.

During the warranty period, the lawn mower needs to maintain and configure the carburetor. It is recommended to do this in an authorized technical center.

What to do if the engine does not start?

If the lawn mower fails is not possible, then the first thing is to check the presence of fuel in the tank and its quality. For refueling the tool, it is recommended to use high-quality gasoline purchased at gas stations, the brand of which should not be lower than the AI-92. Savings on cheap fuel can lead to a breakdown of the cylinder-piston group, for the repair of which a third of the cost of Motokosa itself can take

It is equally important and correctly preparing a fuel mixture of gasoline and oil. The proportional ratio of these components of the mixture is indicated by the manufacturer in the manual. Do not prepare the fuel mixture in large volumes, since during long storage its properties are lost

It is better to use a freshly prepared mixture

Do not prepare the fuel mixture in large volumes, since during long storage its properties are lost. It is better to use a freshly prepared mixture.

When preparing the fuel mixture, pour the oil into gasoline using a medical syringe that allows you to accurately observe the necessary proportion of the components

Fuel filter pollution in the tank may also prevent the operation of the lawn mower engine. Therefore, when problems with the launch of the motor, check the condition of the filter. If necessary, replace the filter. It is forbidden to leave the incoming pipe without a fuel filter.

The air filter also needs to be in the test. During contamination, the part is removed, in the field is washed in gasoline and put in place. In the country or at home, the filter can be washed in water using detergents. After that, the filter rinses, squeezes and dries. The dried filter is moistened with a small amount of oil used to prepare the fuel mixture. Excess oils are removed by compressing the filter with hands. Then the part is installed in place. The removed cover is placed back and fixed with screws.

The air filter washed in the fuel mixture, squeezed and dried, is installed in place in the plastic case and covered with a lid

How this procedure is done in more detail you can look at

If all of the above procedures are carried out, and the engine is not started, then adjust its revolutions at idle, twisting the carburetor screw

In the video posted at the beginning of the article, attention is paid to this issue

• Put the tool on the side so that the air filter is at the top. With this location of the chainsaw, the fuel mixture is ensured exactly into the bottom of the carburetor. On the first attempt, the engine will start if you remove the air filter before starting and pour a few drops of the mixture into the carburetor, and then install the dismantled parts to the place. The method is tested in practice.
• If the first advice does not give a result, then, most likely, the problem in the spark plug. In this case, unscrew the candle and check its performance, as well as dry the combustion chamber. A candle that does not show signs of life, replace the new.
• If the spark plug is in good condition, the filters are clean and fuel mixture, then you can use the universal way of starting the engine. Close the carburetor air damper and pull the starter handle once. Then open the damper and pull the starter 2-3 times. Repeat the procedure from three to five times. The engine will surely start.

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.

Malfunctions and their elimination

Electric and gasoline trimmers have typical breakdowns and malfunctions. For devices running from an internal combustion engine, this is:

• problems in the carburetor;
• engine breakdown;
• problems with the fuel system;
• breakdown of the gearbox, starter, muffler;
• blockages;
• Air filter breakdown;
• Problems with ignition coil.

Electric units have specific breakdowns:

With simple problems, you can make a trimmer repair for grass with your own hands.

Why is a trimmer not starting for grass

The most common reason that the unit does not start is the use of poor.quality fuel. The choice of gas stamps below AI-92 can disable the lawnical mower. If high.quality fuel is used, you need to look for other reasons. To do this, carefully check all nodes and systems. The checks are subject to:

The device may not start after prolonged downtime. Before turning on a trimmer for grass, you need to study well the instructions for operation. The solution of many problems is indicated in it.

If it stalls when you press the gas

There are several reasons why a trimmer for grass stalls when gas is pressed:

• The first reason is the dumping of the carburetor.
• Fuel valve.
• Fur valve blockage.
• The weakening and sagging of the carburetor cable or sagging of the fuel intake hose.

So that the described problems with the lawn mower do not arise, you need to carefully monitor the condition of the device and its blocks. Timely cleaning, washing of the unit and spare parts allow you to increase its life.

Starter breakdowns

The most difficult breakdown of the starter occurs when the rope is broken and winding it into the flywheel of the operating engine. As a result, the spring may burst and the pulley plunges. In this case, only a complete replacement of the spare part will help. This breakdown rarely occurs. often:

In this case, it is easy to fix the starter yourself. The manufacturer has prepared a step.by.step instruction for this.

REDUTOR Repair

Caring for the motorcade gearbox consists in the timely lubrication of the unit. The absence of one can lead to rapid wear of the gear and jamming of the gearbox module.

The main malfunctions of the trimmer gearbox for grass:

• severe heating of the gear component due to the use of low-quality lubrication or its absence;
• shaking of the shaft during the rotation of worn bearings;
• staggering or flowering from the bar of the gear ratio as a result of damage to the case;
• Lack of rotation of the output shaft with a knife due to wear on the teeth on the gears.

This happens due to the use of low-quality lubrication or its complete absence. Another reason for the failure of the gearbox is the operation of a trimmer for grass at the limit of its capabilities and the hit of foreign objects. To replace a faulty bearing, a gearbox is disassembled.

Features of the repair of electric models

Electric models of trimmers operating from the network have several main blocks:

Each electrimmer block has specific problems. In the mechanical part, they depend on the presence of a fishing line used as a cutting element. Reasons for the termination of work:

You can identify the problems of the electrical part of the electrocos using special tools:

To eliminate problems, a soldering lamp is needed.

• a malfunction of the power cable;
• problems with an outlet and fork;
• the failure of the control handle;
• combustion of the starter winding, engine replacement is required;
• Contact breaks can be corrected independently using a soldering lamp.

Features of operation

The Stihl FS 250 lawn mower is characterized by a simple device, not complicated maintenance. The structural and technological parameters are similar to the Stihl 120 gas station, the difference lies in the higher engine power and the size of the cutting device.

The instructions for the operation of the manufacturer indicate in detail the rules of maintenance of the STIHL motorcosa, the timing of routine work and replacement of consumables, recommendations regarding the possible malfunctions of the unit, which can be eliminated independently.

As a fuel, the original fuel mixture of Stihl Motomix is ​​recommended (stored for 2 years), not containing benzene, tetraethylsvin, with a high octane number. In case of inaccessibility of the specified fuel, the prepared mixture of TIRAS AI-90 and the STIHL HP or HP Super for two-stroke engines in a ratio of 50: 1 is poured into the tank. HP Ultra is considered the best oil. Such a mixture is stored for no more than 1 month.

What is a trimmer for grass

Under the trimmer suggest motorcycles or electrocos. This is practically one of the variety of lawn mowers (manual mower) that are created for mowing the grass. This is a modern braid braid. At first, they were developed to carry out agricultural work, but the main use of trimmers was specifically the mowing of lawns. For the first time, the thought to make a trimmer for the grass occurred to the South American businessman J. Bollas. Passing by car through an automatic car wash, he saw that the principle of spinning brushes can be used for beveling agricultural crops.

After that, he collected a simple trimmer for grass from a tin can (as a coil) and a fishing line, reached into the holes drilled in it. He installed the resulting design on a pole, on which a moped engine was previously mounted for earlier. The device is a mowing not only wheat, and grass. The device of the coil of the trimmer for the grass and it leaves the coil. a fishing line for a trimmer does not why stalls. Realizing that on the sale of braids for the grass he will earn huge funds, the businessman improved his product and gave him the title of “Excellent weeds”. A feature of the invention was the possibility of a bevel of grass around the trees. the forest perfectly cut off the grass, but did not injure the bark.

The main purpose of such a tool was the bevel of grass in small areas in places where traditional wheeled technique cannot be applied:

• in the presence of a huge number of shrubs;
• in gardens with a huge number of trees;
• near fences and fences;
• If the site has an uneven relief.

All trimmers for grass have a bar in their own composition. the main constructive element. A gasoline or electronic engine is attached to the rod from the 1st end, and a coil with a fishing line is put on the other-the main working element. With all this, the type of transmission can be at least any. it is limited only by the ability of the manufacturer and commercial parameters.

When it is necessary to adjust

Carburetor adjustment is necessary in the following cases:

• The new engine was running out (4-5 liters of fuel mixture were used);
• The composition of the fuel has changed (brand of oil and gasoline);
• The weather changed (it became hot, cold);
• Air vacuum has changed (concerns mountainous areas);
• after long.term storage;
• the load on the engine has increased (after changing the tool and t.D.);
• Due to the vibration, the adjustment screws spontaneously unscrewed;
• Fuel consumption has increased, the carburetor shimmers the fuel;
• Flapse quickly appears on the electrodes of the candle (while the fuel mixture is prepared correctly);
• The motor starts and immediately stalls or is poorly gaining momentum;
• Gasoline does not enter the cylinder;
• A large amount of exhaust gases.

The design of the walk.behind tractor

An important driving part of the described device is an engine that can function both on gasoline and diesel fuel. Such an component of equipment can be either two.stroke or four.stroke. A characteristic feature of these engines is that they are mounted in them specially designed for this regulators of rotation, capable of simplifying the process of work

Engine power can vary from five to ten liters. It is also worth noting that with the greatest difficulty during the repair, experts face precisely in this part of the walk.behind tractor

The next element of the device is a transmission that has a certain number of variations:

An aggregated system is considered an important component of the described device, thanks to which additional agricultural devices becomes possible to an engagement. Management of this mechanism can be located either on its handles or on steering rods. And also in this place is the clutch and gas clutch

Why you need to put a knife on a trimmer for grass

A trimmer for grass with a knife installed on it is most conveniently used for a more comfortable mowing of high and loaded grass in the country. a fishing line for a trimmer on a motorcycle in such cases does not cope. Thin torn very quickly. Using Tolstoy 2.3 mm cord or homemade rods with cables forces the vegetation to wind up on the rogue. This increases the load on the engine. As a result, the piston group and other mobile units of the unit wear out very quickly.

If the mowing of a weeds is produced by an electric trimmer without a knife, only with a fishing line, even a thick with a figure section, the problem cannot be solved. There is always a risk of overheating the electric motor and disable flexible shaft. And it’s all in a large torque of the electric motor. The grass wound on a spindle creates strong resistance to the shaft resembling a speedometer cable that does not withstand and twist.

In order to protect the equipment from premature wear, manufacturers have provided the ability to install special knives on the grass for grass for grass. The design and shape of existing cutting elements allows you to easily cope not only with coarse and outgrown with grass, but also to successfully fight the young shrub.

If the chainsaw does not start anyway what to do

The main reasons for why the chainsaw is not started. over, this applies to the tools of different brands STIHL, Husqvarna, Partner, Makita, Champion and others. Friendship has a different principle of operation, but in general, the search for a malfunction should start with the ignition system, or rather, the inspection of the state of the electrodes of the candle. If the manipulations do not help get the desired result, then it is necessary to resort to more serious actions. This means that the following actions need to be performed:

• Check the serviceability of the carburetor and set it up
• Measure the value of the engine compression, and then draw the appropriate conclusion about its serviceability
• Carter compression is checked

Checking the compression in the cylinder allows you to assess the state and serviceability of the CPH. To measure the compression, a compressometer will be required. It is screwed into the candle hole, after which the starter handle is twisted. The compressometer shows the corresponding pressure value in the cylinder. This value should be at the level of 8-12 atmospheres.

If the pressure value is significantly lower, then this is a direct sign of the device malfunction. The cylinder piston group is replaced with a malfunction with a new. When installing a new CPH, it is necessary to carefully treat all the parts with oil so that chips and bullying are not formed at the time of starting the engine.

If there is no compression in the crankcase, then the chainsaws will also not start. The reason for the reduction in the pressure in the crankcase is the gasket, or rather its damage. This gasket is placed between the cylinder and the crankcase and, to make sure of its serviceability, such manipulations should be performed:

• Disconnect the fuel line from the tank
• Lower the tube into a container with the prepared mixture of gasoline and oil
• Start the chainsaw engine
• If the engine starts and at the same time fuel is sucked, then this indicates the serviceability of the gasket

If the fuel is not absorbed, then you need to replace the gasket of the crankcase.

The carburetor is an important and most complex element of the chainsaw. If all the above actions did not help to get a positive result, then this suggests that the carburetor is faulty. The main malfunction of the carburetor is to clog its channels and nozzles. Less commonly, membranes and other elements come out. In any case, you will need to disassemble the carburetor of the chainsaw, clean it and replace the failed parts.

As you can see, the reasons for the fact that the chainsaw is not started is enough. To find out what exactly happened in your case, you need to remember the symptoms the day before. Perhaps, before the chainsaws stopped starting, the engine failures were observed, power and performance decreased, and other breakdowns were also appropriate. Based on these technical symptoms, it is necessary to start the search. If you do not know where to start, then diagnostics should be carried out in order, as described in the material.
