How to assemble a gas handle on a trimmer

Repair of trimmers should be carried out as soon as possible when the first signs of breakdown occur so that insignificant malfunctions do not lead to more severe dilemmas. For all models, the presence of such main nodes and structural parts: the drive system (motor), gear devices, the working part (knife or fishing line), belts and handles. Damage can occur in at least some part, but some nodes fail more often others more often.

Motokosa working on gasoline or electricity (like various models, from different manufacturers) differ in design and disperses of problems. Part of them can be easily removed with your own hands, while others will require more than half a year repair or appeal to the service center.

Common malfunctions of electric trimmers

Electric trimmers for grass differ from gasoline devices with a more simplified design. Conditionally electric braid is divided into mechanical and electric part. Accordingly, the same groups of malfunctions are distinguished, arising to these equipment.

Most of the breakdowns can not be visually identified. For this you will need to use various devices. You can visually determine the following:

the integrity of the power cable is violated (insulation is broken from it, or it is clearly interrupted);
sustaining or jamming of the trigger button;
mechanical external damage to motorcycles;
problems with the cutting part;
stopping braids for grass when clogging with grass;
Damage to the fork.

To find out which part has broken in other cases, you will need to disassemble the electric shock and sequentially check the most likely options

At the same time, they pay attention to the external manifestations of deviations from the normal operation of the device. They contribute to the establishment of the cause

Repair of an electric trimmer for grass will require the presence of the following devices and tools:

Electric braids for grass often do not work due to causes that are not directly related to them, but caused by a decrease in the supply voltage in the network or the ineffective state of the used outlet used.

The main malfunctions of the starter of the trimmer for grass

It is not difficult to determine the cause of the breakdown of the starting device. There are several main options:

These details are shown in the photo below.

It may happen that the starting mechanism will be accidentally broken. The consequences will turn out to be deplorable if the ragged rope is wound around the flywheel of a working internal combustion engine: then the spring bursts, the pulley will tear off. But such cases when a complete replacement of the starting node is required, they rarely occur. In most cases, to fix the mechanism, it is enough to put a new spring or replace the cord.

Removing and disassembling the starter, replacing broken parts

To repair the starter of the trimmer for the grass, you will need to disassemble it first, and then collect it. This process is not a particularly difficult occupation. For work, you will need a screwdriver with the tip of the desired shape.

Everything should be done carefully, observing safety precautions, mainly that the spring does not injure the master if an accident.

Parsing the starting node

They disassemble the launch mechanism in order to install new parts instead of broken in the following sequence:

spin a screw with a screwdriver, fixing the pulley with a starter lid;
take out a spring and antennae;
Remove carefully with the pulley (you need to unscrew the head or work, having dressed the glasses and gloves before);
determine why the launch mechanism has broken;
If the spring collapses almost completely, then it is replaced;
When the spring exits from the hook, it is installed in the original place, bending the antennae before this (the photographs show the laying process);

To change the spring, you should work carefully and accurately: it can, under the influence of the effort caused by the installation of it in place, accidentally burst. Even if you carefully remove the video, then the spring strip flies very quickly from the coil and can injure your hand with its sharp edges.

Immediately putting a springy plate in the same place does not always work. It often slips, so attempts are required to repeat until the desired result is achieved.

Starter assembly

The assembly of the starting node is carried out in a number of stages:

When making the stated manipulations, it is necessary to lay two goals. If this is not done, then the spring over time damage the plastic cup, and when it is pulled. Because of this, a feeling appears, as if the spring had flown. To eliminate such a drawback, you need to install this part of a larger length or an additional goal.

When such spare parts are absent, you can just unscrew the screw a little, and the starter knot will begin to work without shaken. But this option is temporary. it is better to repair qualitatively as quickly as possible.

Spring tension

After installing the spring, it should be pulled. The following actions are performed for this:

Remove the handle from the starter cord;
Then the rope is inserted into the coil groove;
They stretch the spring, rotating the coil in the direction opposite to the clock of the clock arrow (reviews);
make the desired number of revolutions specified in the instructions for the use of the trimmer model used and the corresponding length of the cord used;
At the very end, the rope is threaded into a hole designed for this, located in the starter cover;
put the handle in place, fixing it with a node.

If after the repair the spring continues to fly, then you can get rid of this in the following ways:

Generator Won’t Start?. Check This First!. Video

Squeeze the suitable piece of the plate into the groove at the location of the spring hook;
drill holes on two sides of the groove in the coil, into which the spring hook is inserted and fix it using a wire.

Replacing a torn cord

A torn rope is replaced in the following sequence:

The old cord is removed;
choose a suitable rope (thickness and length);
Having reached it through a special hole in the coil, a knot is tied;
Sprinkle a spring, producing the required number of revolutions;
Fix the pen.

It is better to stretch the spring plate along with the partner so that the edge of the cord does not hit the starter mechanism.

It is easy to assemble a starter on a trimmer and wound a spring, only you should do it carefully and with caution. For different models, the gas tanks of the launching mechanisms are the same, so they are repaired in a similar way. In this case, there are some nuances associated with their constructive features.

As a rule, devices designed for mowing grass and similar to them are quite bulky.

The vast majority of trimmers of any type are delivered in disassembled form, packing in a cardboard box, so before starting work, such an apparatus must be assembled.

In addition, a trimmer for grass often has to collect after winter, because some of the owners disassemble this device so that during storage it takes less space.

What to do if the engine does not start

In this situation, you have to find out the cause of the malfunction. It is worth checking fuel and air filters. The latter can be washed in gasoline or in water with a detergent. Then it is squeezed and dried.

Before returning to its place, it is advisable to wet it a little (2 drops) with oil for a two.stroke engine. In the case of a breakdown of the fuel filter, it will have to be replaced and without it it is forbidden to turn on the device.

Also, the cause may be a broken starter in a benzocos. Some users pull the launch cable too much, which is why it can break. This, in turn, will require the replacement of the starter.

Removing and disassembling the starter, replacing broken parts

To repair the starter of the trimmer for the grass, it will be useful to disassemble it first, and later Collect. This process is not a particularly difficult occupation. For work, a screwdriver with a suitable shape is useful for work.

Parsing the starting node

The start.up mechanism is disassembled in order to establish new details of the incorporation broken in the subsequent sequence:

spin a screw with a screwdriver, fixing the pulley with a starter lid;
take out a spring and antennae;
Remove the pulley neatly (it is necessary to unscrew the head or work with all this, dressing for earlier glasses and gloves);
determine why the starting mechanism has broken;
If the spring was actually destroyed by one hundred percent, then it is replaced;
When the spring exits from the hook, it is installed in the original place, bending the antennae before that (the photo shows the styling process);

After the spring plate is installed inside the groove, carefully make it twisting. To change the spring, you should work intently and carefully: it can, under the influence of the effort caused by the installation of it in place, to break through

Even if you carefully remove the video, then the spring strip flies very rapidly from the coil and can injure the hand with its sharpened edges

drill holes from the 2nd sides of the groove in the coil, into which stick the sprout hook and fix it with a wire.

Starter assembly

The assembly of the starting node is carried out in a row of steps:

The coil is turned over, installing it so that the spring bend will definitely stand in the groove of the case, as in the photo below;

When making the stated manipulations, you must definitely lay two goals. If this is not done, then the spring over time damage the plastic cup, and when it is pulled, the jerking off will begin. Because of this, there is a feeling that the spring has flown away. In order to remove such a defect, it is necessary to install this part of a larger length or an additional goal.

When such spare parts are absent, you can just unscrew the screw a little, and the starting node will begin to work without shaken. But such an option is temporary. it is better to repair excellently as a razor as possible.

Obvious advantages of roller lawns:

The best result will be required to comply with some rules for laying the lawn and high.quality raw materials. Therefore, in the store, before buying, you need to make sure that the rolls are really high.quality.

The parameters of the rolls are approximately the same: 2 x0.4 m, a turf 2 cm thick, the height of the grass is not more than 6 cm. To check the quality, you need to expand the roll and make sure:

lack of weeds and pests,
uniform height of the lawn,
absence of voids and prophashin,
strength and density of the root system of plants.

The variety of the lawn should be taken into account: park or sports. Depending on this, the lawn will be shade.tolerant, drought.resistant, resistant to trampling.

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.

Maintenance and prevention of launch problems

So that the tool serves longer and does not create problems, keep it clean and regularly maintain.

Do not store the refueling lawn mower: leaving it for more than 2 weeks, and even more so for the winter, drain the remaining fuel from the tank, then start the motor and let it work until it stalls yourself. Leaving the tool for the winter in the barn, wrap the motor and knives with an oiled rag.

For lubrication of a 2.stroke motor before storage, unscrew the candle and raise the piston with the starter to the very top. Drip a little motor oil from the syringe and use the starter several times cranks.

In the spring, before the first use after downtime, it is advisable to check the candle and filters, disassemble and rinse the carburetor, even if there are no problems with the launch.

Common malfunctions of electric trimmers

Most of the breakdowns can not be visually identified. For this you will need to use various devices. You can visually determine the following:

the integrity of the power cable is violated (insulation is broken from it, or it is clearly interrupted);
sustaining or jamming of the trigger button;
mechanical external damage to motorcycles;
problems with the cutting part;
stopping braids for grass when clogging with grass;
Damage to the fork.

To find out which part has broken in other cases, you will need to disassemble the electric shock and sequentially check the most likely options

At the same time, they pay attention to the external manifestations of deviations from the normal operation of the device. They contribute to the establishment of the cause

Repair of an electric trimmer for grass will require the presence of the following devices and tools:

How to independently disassemble and repair an electric braid

Before disassemble and repair the electronic braid, you should check the condition of the outlet and the voltage in the network. If its value deviates from the norms indicated in the operating annotation, then you should not even try to work as a device without a stabilizer designed for appropriate power. Another electric motor may fail. Only after determining the fact that the cause of the trimmer refusal is specifically associated with it, we can begin to analyze the mechanism with the repair goal.

Repair of a gasoline engine, carburetor and gearbox

Problems with the engine can be caused by disadvantages with the piston system, oil seals, rings. To remove them, you need to remove the drive motor.

Find what exactly became a prerequisite for the breakdown, hard. In the presence of a guarantee, the mechanism should be attributed to the service center for diagnosis and repair. If you turn to the specialists for help, there is no ability, then it should be noted that the substitution of piston rings is often required. To do this, it will be useful to disassemble the engine, get the piston. Do this in the subsequent sequence:

Remove the lid of the plastic case, unscrewing the screws or pressing the clamps;
disconnect the bar with the crankshaft;
Remove the cylinder head;
take out the piston and rings;
As needed, they make their substitution;
make assembly in a revolutionary sequence.

How the piston is placed and the seals are replaced during the repair of the motor, it is clearly shown in the rollers further:

With constant use of the lawn mower, a gearbox may break. Histers, bearings wear out in it (they can also break). So that this happens infrequently, this node should often be lubricated. Frequency is actually always indicated in the operational annotation to the model used (not more often than once per season). The video below can serve as an annotation for repair.

Read adjusting the ignition coil on the trimmer video

To grease the gearbox, unscrew the cork and just squeeze the suitable lubricant inside, scrolling the shaft.

Without the help of others, the carburetor can only be removed and cleaned, also change the gasket between it and the engine. The density of the node in home criteria is quite problematic to find. The main thing is to correctly assemble the equipment after repair, so that the trimmer for the grass works without troubles.

Dismantling and repair of the electric part

Dismantling of electrocos for the repair of its electronic part is carried out in such a sequence.

Put a trimmer for grass on a flat surface (for example, a table) that does not contain excessive objects.
Spin the screws of the lids located on one side.
Remove the unscrewed half of the case, getting access to the start button, the electric motor, the brush unit, bearings, electronic connections (these elements are shown in the photo below).

Brush and bearing nodes are presented in the photo below.

The braid for the grass will work without a thermallara, it will only come in handy for the time without the help of others to inspect the temperature of the electric motor, sometimes letting it cool. You can also install a new similar sensor.

The starter start button can be checked by the jumper with a jumper of its contacts. If the trimmer for the grass earns, then the inconsistent is understandable. But such an option is dangerous. Everything should be done neatly so as not to get an electronic shock. To change the button, you should use a screwdriver to remove it from the place of landing and attach wiring with an old one to the latest. After the substitution is necessary Collect

electrocos, and then check its performance.

The substitution of brushes is required if they collapsed. With all this, it is quite old to remove from the grooves, and the new ones are installed in their place.

The substitution of the bearing is a rather complicated operation, as it can grab and not be removed from the shaft of the motor

Tighten or knock it down carefully so as not to destroy the rotor or landing site

When a trimmer electric motor for the grass fails, and you need to change it with a new one, you should carefully remove the fan and bearings, and then install them in the same place. In terms of substitution, the substitution is actually comparable to the acquisition of a new mechanism. Its conduct in the absence of experience with electric motors is better to entrust to the specialists.

Ordinary breakdowns of trimmers, how to remove them with your own hands

Like any technically not simple device operating in difficult conditions, trimmers for grass can fail. Very often the causes of malfunctions are the violation established by the manufacturer, the operational rules of a mechanized braid for grass. For example, non.compliance with the modes of alternating work and technological break, or irregular lubrication of the gearbox and other parts, which leads to overheating of parts and mechanisms.

Distinctive breakdowns of trimmers, very often manifested in a variety of types of this device, are considered:

The failure of the work head of the tool, which in most cases is loosened in violation of the supply of fishing line due to the reason for its confusion or sticking, and also damage from the mechanical factors of the bottom of the coil;
breakdown of carburetor motorcosa;
A break in the intermediate shaft of the tool, the basis of this breakdown can be cutting the slots with which it connects to the motor shaft;
Damage to the connecting bushings of the root bearing installed between the cable and the head of the trimmer for the grass.
fuel and air filters pollution.

In most cases, gluing and confusing the fishing line in most cases occurs with its unfavorable quality and violation of working modes, which leads to overheating of the head of the trimmer for grass and fishing line. To remove this breakdown, you need:

Remove the lid from the trimmer head, for which press the latches with your fingers, and carefully unfasten the lid.
Remove a reel with a fishing line from the head. It must be removed carefully so that it does not jump out and does not fly into the grass placed under it, the spring.
Dissolve a confused or sticky fishing line for a trimmer, and charge it by a new. Fold the fishing line for the trimmer in two, and fix the middle into a specialized groove on the middle disk of the coil, which divides the bobbin into 2 compartments.

To wind the fishing line for a trimmer to the coil of a trimmer for grass, first of all, it is necessary to fold it in two, and the middle is fixed in the suitable groove

Having wiped a fishing line for a trimmer to the heel of the head of a trimmer for grass, its free ends must be fixed in grooves on the bobbin

For a trimmer for grass, it is better to use a fishing line for a trimmer of the diameter that is recommended for using the manufacturer of the tool. When purchasing, it is necessary to buy a cord of more popular brands, and not take the first fishing line for a trimmer of lower price and an unfamiliar brand.

If the gasoline trimmer for the grass does not start or stalls its motor after starting, the basis may be a breakdown of the carburetor or pollution of the fuel filter. Damage in the operation of the carburetor can occur when clogging, and sticking on the oil valve film of this device. This can happen if you do not develop a fuel mixture to the end, and leave it in the tank for a long time.

To clean the carburetor, you should remove it from the motor and disassemble, disconnecting the primer (manual pump for pumping fuel), all gaskets and needle. Any detail individually should be washed by the carburetor cleaner, blowing the liquid from the cylinder into all its holes. After washing, when the details are dried out, you should assemble the carburetor and install it in place.

The engine on gasoline can also stall when clogging the fuel filter with the remains of grass and dust. It, like an air filter, must be removed from motorcycles and washed with gasoline. After drying, the filters should be installed in place.

Often in trimmers with a curved bar overheat or the shaft of a mowing head ceases to rotate. This happens when the indigenous bearing is not lubricated or damaged. It is two bushings placed in one another. This part must be smeared or replaced with a new one, if the bushings are broken and the shaft is jammed. To do this, you need to:

To replace the radical bearing, the trimmer head should be removed

To replace or lubricate the root bearing of a trimmer for grass with a flexible shaft (cable), it is necessary to remove the mowing head and casing to protect

To extract the indigenous bearing from the hole of the bar, it is necessary to unscrew the lock screw in advance

To eliminate other breakdowns of a trimmer for grass, including a shaft break or failure of a motor, you will need the help of a professional master who may present a special repair service.

Repair of the gas handmade handle with your own hands

Details: Repair of the gas handle handle with your own hands from a real master for Olenord.com.

An indispensable tool for a modern summer resident or the owner of a private house is a lawn mower, which allows you to effectively and efficiently bring the adjacent territory in order. The period of active use of motorcycle is in late spring until October of the month. Modern units are equipped with powerful and hardy ICEs, enhanced transmission and main nodes. Despite this, physical wear, production marriage or improper exploitation leads to the failure of a trimmer for grass. In order to repair a trimmer for grass with your own hands, you must have at least basic knowledge in the field of technology and a little experience in its repair.

The main node of any gasoline tool is the internal combustion engine (ICE), which through various methods transmits a rotational moment to the executive body. In a modern benzocosa, a duralumin rod (pipe) is used as an element of the transmission between the motor and the trimmer head, inside of which the drive shaft is located.

Thanks to a highly reserved engine, the frequency of fishing line can reach 13 thousand revolutions per minute depending on the producer of the braid for grass. In order to exclude mechanical and temperature damage to the gearbox, a special opening is provided for the introduction of ointments in its body. As a facilitating headset for the owner, during prolonged work, all modos models are equipped with a strong belt over the shoulder.

Champion Help Center: 3000 Watt Inverter Starter Motor and Ignition Coil Replacement

Regardless of the manufacturer, almost every model comes with fishing line and steel knives.

The transverse section of PVC Lines for a trimmer for grass can vary from 1.5 to 3.0 mm.

Made from a durable polymer, during kosba it is subjected to intensive wear and, as a result, a break. Therefore, from time to time it is necessary to check the presence of a fishing line in the head and, if necessary, replace it. It is recommended to purchase an additional bobbin for quick replacement with a reel with a fishing line ending.

The trimmers presented today on the market for ICE grass are equipped with a D-shaped, U-shaped or T-shaped handle, where the main controls of the unit are located. For example, in a spit with a U-shaped handle key and a “stop/start” toggle switch are located on the right handle. In the D-shaped version of the gas control key, the gas adjustment key is located directly on the bar.

In view of the presence of many nodes and details, the repair of a trimmer for the grass with your own hands involves the elimination of breakdowns that prevent its normal operation. It should be noted the most basic malfunctions of gasoline cos:

The engine of the trimmer for the grass does not gain momentum;
Breakdown of the cylinder-piston group (CPG);
Ignition malfunctions;
There is no connection between the internal combustion engine and the trimmer head;
Mechanical knocks when operating the unit.
Repair of the CPG lawn mower

The main node of any internal combustion engine is the cylinder-piston group (CPG), which can fail due to wear of parts of parts or low quality of the fuel mixture.

Lubrication of the rubbing nodes in a benzos is carried out by adding a certain proportion of oil to gasoline. This process can be disturbed due to the old oil dropping in the form of sediment. In this situation, when the trimmer for the grass is launched, the motor overheats greatly and in a matter of minutes the most expensive breakdown occurs. To eliminate the malfunction, a complete replacement of the CPG, namely: piston, seals, cylinder and piston rings will be required. If you are not a technical engineering master and do not have experience with technicians, then the engine is unlikely to be corrected without the help of a specialist. In detail with the stages of repairing a piston trimmer for grass, you can find here.

When you fail to ignition of the lawn mower, a spark on a candle disappears and, as a result, there is no ignition of the fuel mixture.

It is important enough in the current situation not to rush with the replacement of the coil, since the cause of the breakdown may be in the absence of contact in the switch on the control handle.

An important point in the search for the ignition of a trimmer for the grass will be diagnosed with Sich, where the distance between the lateral and central electrode should be 0.5-0.7 mm. In addition, it is necessary to pay attention to the sealing ring of steel on a candle, the loss of integrity or the deformation of which can lead to etching of the combustion chamber and, as a result, reducing the power of a braid for grass.

If the replacement of the check of the electric circuit, candles and its contacts did not give positive results, then you should pay attention to the ignition module of the trimmer for the grass, namely to the gap with the flywheel. Regardless of the design features and the manufacturer of the lawn mower, the distance between the ignition coil and the flywheel should be no more than 0.2 mm. To restore the optimal value of the clearance, it will be necessary to relax the bolts of fastening the coil and a special measuring probe set the ignition of a trimmer for the grass.

A clear sign of malfunction of the engine power system is the absence of traces of the fuel mixture on the electrodes of the candle, which may be associated with the following defects:

The fuel system of the trimmer for grass

In connection with a clogged hole in the gas tank, a vacuum is created, which prevents the normal flow of gasoline into a carburetor;
In view of the low quality of fuel and the hit of foreign particles, the fuel filter installed in the tank clogged;
not the intake of the mixture in the combustion chamber as a result of the carburetor.

It is possible to quickly determine the cause of the malfunction by dismantling the fuel hose leading to the carburetor. If the fuel mixture flows in a thin stream, then you should pay attention to the carburetor. In the absence of a jet, it is necessary to clean the thin needle of the cabin (a small hole in the gas tank cover) or replace the fuel filter.

If the fuel enters the carburetor, then it is necessary to clean it or adjust. Adjusting the carburetor of a trimmer for grass implies the restoration of optimal mixture mixing.

Carburetor trimmer for grass with tuning screws
