Gasoline gasoline does not twist the disk. Damage to constructive details

trimmer for grass The motor does not rotate the head

Trimmer repair is needed when the device does not cut or it works incorrectly. All owners of personal houses and suburban areas are familiar with an unnecessary vegetation, which is sometimes difficult to get rid of. As clear, progress does not stand in one place and new developments and useful inventions arise in all areas. It hurts agriculture. You no longer need to mow the grass with old ill.wing devices, modern benzo.cosers came to the rescue, which are able to get rid of vegetation in the most inaccessible places.

gasoline, does, twist, disk, damage, details

A gasoline trimmer can be mowed grass even during cloudy weather. The engine did not check, but works with an excess. Not an air damper. It is easy to care for a personal plot using this unit painfully, and to cope with this occupation will be able to at least some adult man.

Despite its multifunctionality, as it doesn’t matter what kind of technique, trimmers for grass tend to break and fail.

Not every person can do the repair of the lawn mower with your own hands, because for this we need the ability to repair electronic devices, but now we will try to figure out how to start a trimmer for grass without a starter and how to make his work with your own hands can be debugged in general.

Breakdown of a trimmer for grass and methods for their elimination trimmer repairs of a grass implies the elimination of all malfunctions, which interferes with the normal functioning of the unit. Among the most common, the following can be noted:

  • CPG breakdown (cylinder-piston group) of the engine;
  • The trimmer for the grass fails when trying to increase the speed of work;
  • Ignition coil breakdown;
  • There is no connection between the engine and the gearbox;
  • There are extraneous sounds during work;
  • The engine cannot develop the desired speed.

The breakdown of the engine CPG can occur due to the low quality of the fuel or wear of the motor parts. As you know, the lubrication of the piston group is carried out due to the clock, which is added to gasoline. 2. With a kosbe fishing line trimmer for grass and the head does not spin t. E. The engine works and. In the old oil, the lubricant falls in the form of a sediment, which makes the oil unsuitable. If you continue attempts to launch a trimmer for the grass, you can ruin the motor in a matter of seconds, and this will entail additional costs of repairing a trimmer for grass. This breakdown is considered the most expensive. At idle, and do not leave gasoline on a trimmer for grass works, but on idle. To eliminate it, it is necessary to replace the piston group assembly, to be more precise, it may be necessary to replace the cylinder, rings, pistons and seals. In such cases, it is unlikely that you can do without additional help, unless you yourself are a master and know how to handle a similar technique.

Possible trimmer malfunctions for grass and ways to eliminate them

Air filter is contaminated;. The old fuel mixture is flooded.

With the most common faults of the trimmer for the grass, it was possible to understand the grass, now it is worth finding out another important point: what breakdowns can be fixed yourself and how to do it, and which you need to immediately contact the service center?

We are trying to solve the problem on our own:

  • If a wire limiter disappeared from the spitt head, then it can be scheduled in place with copper or aluminum wire, but you can not do this, but then it is more careful to do the work, not allowing the possibility of a cut;
  • If the “VCL-Opl” button, armed with a soldering iron, you can replace it with a new one;
  • If the bar has broken, it can also be reanimated independently;
  • If the fishing line for a trimmer has broken or ended, buy a new roll of the desired diameter, then disassemble the drum and wrap it on the bastard;
  • If you feel the vibration when operating the engine, then it’s time to grease it with oil. It is necessary to do this procedure about once a year.

Now we consider the possible breakdown of trimmers, which is better to contact the service center:

  • If the tool engine is out of order for an incomprehensible reason for you, it is better not to take up the repair. Perhaps you can’t collect it back or there was a serious breakdown, having taken up the repair of which, you will finally disable the unit out of order;
  • The repair should not be started yourself if on the indicated solutions, it is not possible to eliminate the fault.

Remember! No matter how hard you try to repair a trimmer for grass at home, sooner or later you will have to contact the service center, because any equipment is not eternal, but you can still extend its service life. Qualified specialists will conduct diagnostics and will be able to identify the true causes of breakdown.

In addition to receiving qualified assistance, on our site you can always choose the desired product from the catalog and purchase it with a quick and convenient way without leaving home.

The personal plot will not have a neat appearance if the bushes rushed out in its garden and park zone and the grass formed a thick cover. This indicates the neglect of the site by the owner who does nothing even to cut the lawns. But mowing grass. The lightest occupation on the site, because various equipment has been created for this work.

The advantage of a gasoline trimmer for grass

For example, a trimmer for grass. very convenient and productive, light, reliable and practical device. It can be electric with a small weight, or gasoline with high performance. Basic gasoline are more common, as they have a fuel tank and can work at a distance from electrical communications. Perhaps the only minus of a gasoline trimmer for grass is that it, like any technique, periodically fails. But in this matter, it has an advantage, since for people who understand a little in technology, it is possible with their own hands.

The engine of the lawn mower is not started

Everything is simple here, a few main points for any motors: that the engine works good compression, its absence will not allow the motor to start. The following that you need to check this ignition, there will be no ignition without a spark. The clogged fuel system will make it difficult to feed the fuel and the contaminated exhaust system also greatly complicate the launch of the motor.

Perhaps this is the main thing you need to check. The most popular repair scheme is the exclusion method. That is, in order we cut off options for faults, I will tell you more:

Fault of the piston group

On the entire two.stroke technique that is brought to us, we first check the bully on the piston and cylinder. You can do this by unscrewing the 2 muffler bolt and taking it off, shut up the exhaust window. If the piston is smooth and the rings are springy. this is good if the piston is in damage or rings and hesitated. this is not acceptable. The cause of the breakdown is overheating, the old fuel mixture or the absence of oil in the solution. The only panacea is a major overhaul with the replacement of the piston.

This Is What Happens To Tires After An F1 Race

Trimmer ignition malfunctions

Next, check the spark, leaning a candle to the mass and scrolling as a starter as follows. If there is no spark, disconnect the wires from the coil to exclude the switch. We perform all operations only with a new candle. Dragged, pumped, wiped candles will not work. There are also cases when a spark disappears on a heated spit and does not appear until complete cooling. Poor contact of the cap and high.voltage wire is possible. If the spark does not appear, the ignition coil replacement is necessary.

Fuel system pollution

If everything is in order with the motor and spark, let’s try to start. We recommend that you sprinkle the carburetor cleaner into the combustion chamber, under a candle or in the carburetor window. The motor will start and most likely stall, repeat the operation several times. If nothing helps, you need to try to clean the carburetor. We do not recommend climbing on our own, due to the presence of small details or their absence as a result of inexperienced repair. Fuel system pollution is the most common malfunction.

Carburetor malfunction

Unfortunately, cleaning the carburetor is not a panacea and it is not always possible to clean it completely. Even ultrasound and a good cleaner are sometimes powerless. Also in carburetors often fail: needle, check valve, accelerator valve, membrane, needle and saddle. Someone will say what to break there, but the saw carburetor is structurally more difficult than the car carburetor. In many cases, it is necessary to change the carburetor of the whole or some of the parts.

The clogged exhaust motorcycles

Since oil is present in gasoline, it burns and releases a lot of burning, which is postponed in the muffler and graduation window. On some trimmers, a mesh is installed. a flame arrester, it also needs to be cleaned. Muffler either change or try to burn. My experience allows you to determine whether the exhaust is clogged, just pulling the starter. If you find a dozen in the window, mcorm it, he should not get into the combustion chamber. Use good oil with low smoke emissions.

The most common breakdowns

Any technique sooner or later fails. It is important to know how to repair mowers, because not in all cases you need to contact the service center.

The braid does not cut the grass

In most cases, the cause is dumb or severely damaged knives. To achieve the best results, just change the knife every year. Choose a knife suitable for your model. When the knife is swept away, you can sharpen using electrofig or file. When sharpening, be sure to use goggles and gloves. Angle of sharpening on both sides. about 30 degrees.

Simple sharpening devices can be purchased in stores. Before installing them, it is necessary to turn off the mower from the network and adjust the cylinder positions in such a way as to highlight the maximum cutting gap.

In cylindrical braids, the gap between the knife and the cylinder should be less than the thickness of the sheet of paper. Some of the most modern models have regulators with notches. In other cases, you will have to use keys and screwdrivers to carry out the necessary adjustments. Follow the uniformity of the gap along the entire length of the cylinder. To check the adjustment, insert a sheet of paper between the cylinder and a knife, slowly rotating with your hand. Gradually adjust on both sides until the paper begins to cut purely at each point of a motionless knife.

It is difficult to move the mower

  • When the mower hardly moves along the lawn, you may try to remove too high grass and you will have to adjust the level of mowing. When seizing rollers or wheels, they need to be inspected to make sure that there are no scraps of grass and garbage. Most likely, they need to be removed and cleaned.
  • If an interference for air is formed, then the lifting force will decrease on the mowing air pillow, and it will become difficult to move it. Air lack leads to overheating of the engine. Disconnect the power and remove the remaining grass from the air intake grilles.

The technique does not turn on at all

Long and wet grass can easily block the knives. Pull the fork from the mains and with the help of a wooden object rotate the cylinder to the other side of the knife until the movement becomes free. For gasoline mowers, this technique cannot be used.

A belt that provides the operation of cylindrical lawn mowers, wears out, stretches and can break through. Remove the belt cover and check, there was a gap or belt just jumped off. Unscrew the mounting screws and move the small leading pulley to a large cylinder pulley. Put on a new belt on a small pulley and slowly rotate the big one, gradually putting a belt on it. Push the pulley to the side to stretch the belt, then tighten the screws.

Before installing the lid, be sure to check the belt tension. the degree of bending should not exceed 4 mm (the indicator may fluctuate slightly depending on the model, detailed information is contained in the user guide).

Gap in the cord

With every use, you unfold, move and turn the cord. This can lead to a break in the internal conductors. For many models, the cord is connected to the screw terminals, which makes it possible to quickly check it and replace it. If double isolation, a two.core cord is connected.

Other models use clamping contacts that facilitate the replacement. Disconnect the power, separate the plastic cover. When you unscrew the clamping bar, pay attention to the connection of the cord to the switch to comply with the polarity of the connection (wire color).

In order to disconnect the cord, insert the hexagonal key into each of the holes in which the conductors are placed. to free the clamp and the conductor. Check where the gap has formed.

If necessary, connect a new cord: twist together all individual wiring of each core, then insert the twisted ends into the corresponding terminals. Pull slightly to check the connection. Then install the clamping bar, the cord bushing and the circuit breaker cover.

Types of lawn mower

The traditional “pushing” technique has long received knives from electric engines, which significantly facilitated the process of work. This type is still very popular, especially among those who want to get a beautiful lawn, but nothing can be compared with the relative novelty of the domestic market. rotary mowers that easily cut off even the highest grass.

Rotor.type mowals are powered only from electric networks, and cylindrical ones. both from the network and from batteries.

Both types are represented by different modifications. Gasoline braids will not be considered separately, but the proposed options for eliminating breakdowns in most cases are identical. You always need to have at hand a manual or apply for advice to professionals if there are problems in care or use.

Cylindrical braids

Their composition contains spiral knives, the totality of which resembles a cylinder. A large toothed pulley placed at one end sets the belt (in some cases, the chain), on the other hand, is worn on the second, a small pulley attached to the engine shaft. The engine can set in motion and a rink that moves the equipment on the ground.

  • Switch lever.
  • Emergency shutdown button and protective lock.
  • Switch.
  • Filter.
  • Air intake grille.
  • Gap regulator between knives.
  • A motionless knife.
  • Knife cylinder.
  • Large toothed pulley.
  • Drive belt.
  • Drive pulley.
  • Lever that regulates the height.
  • Electric motor.
  • Rink.
  • Power cable.

When the cylinder rotates, the knives press the grass to a motionless knife attached to the cylinder, thereby creating a cutting effect resembling the principle of action of scissors. Any damage, even the most insignificant, wear, improper fixing of knives make the operation of technology less effective. The height of the cutting of the grass changes after adjusting the position of the rink or wheel located in the front or rear of the knife cylinder.

Rotor mowers

They have one knife horizontally fixed to the engine shaft. Rotations with high speed make it possible to cut off both grass and other plants. Some models have disks with replaceable plastic knives. they are easy to replace if necessary.

There are wheels in separate mowers, but most models move on air cushions. Here the engine rotates the impeller, which distillates the air masses under the hood. the lifting force is created. Metal knife is placed under the impeller.

Rotor.type mower is made up of:

If we talk about mowers on air pillows, then remote washers are installed above the knife that regulate the height of the grass mowing.

As an alternative solution, you can simply turn the disc with plastic knives to increase or decrease the height of mowing.

In all types of equipment, there can be containers for collecting herbal scraps.

Some gardeners give preference such that it cuts the grass as finely as possible and leaves trim on the lawn as mulch.

The value of emergency switches

All modern lawn mowers have safety systems that will not allow you to start work if both handles or a combination of the shutdown lever with the protective blocking button are not involved at the same time. The switch is turned off as soon as the lever is lowered.

Working with electrical engineering, you need to take care of your own safety. Refuse the use of equipment if you are very tired and cannot be careful. Before the plug in the outlet, check in what condition is the power cord, check that all the devices for protection, knives and fasteners are securely fixed. Wipe the cord completely, lay the excess near yourself along the edge of the lawn from which you will start.

Before work, check if there are any small objects (pebbles, bones) in the green zone that can ruin the knives or be thrown back with the same knives with great force. Keep the cord on your shoulder, grab the handle with two hands. In the process, make sure that the cord is always behind. Before adjusting the height of the mowing, the equipment must be disconnected from the mains.

After completing the work, pull the fork from the outlet, remove the remaining grass from the knives and the air intake grille. Wipe the body with a dry rag. With a spatula made of plastic or wood, remove the mulch from the bottom of the mower near the air cushion. At the end of the season, thoroughly clean the lawn mower thoroughly, rub the knife with an oil rag. Do not forget to lubricate the bearings and regulators. Also check the condition of the power cord: if it is strongly worn, order a replacement to be prepared for the beginning of the next season.


All electric lawns are arranged the same. They have a platform for mounting a motor whose shaft is parallel to the ground. A knife (or two) is fixed on the shaft of the electrical device, with which weeds mush. To make the mowing high.quality, the speed of the cutting electrical tool should be high.

The platform itself for convenience is supplied with four wheels and a handle with the elements mounted on it that control the engine. It is designed to push the device forward and control an electric mower.

Wheel fastening can be stiff and be rotary. In the first case, you will have to raise two wheels in the corners. Rotary ones provide for the use of lower physical strength.

In addition, they “spoil” the lawn less. Therefore, if flowers are planted on the lawn, there are swings, arbors, etc.D., it is recommended to use rotary wheels. Electric lawns with such wheels are convenient for caring for areas under shrubs and trees.

The engine is closed by a case that simultaneously protects from injury by random objects of an operator working with an electric lawn mower. The material used for its manufacture is more often plastic and less often. metal. As you can see, the device of the electric municipal mower of the electric is quite simple.

Why does the lawn mower stall after starting?

After starting, the motor may stall if the carburetor is incorrectly configured or it has been resolved. On what signs can be understood that the reason really lies in this? Very simple, by vibrations that will be clearly felt during the work of a gas station. You can adjust the fuel supply with your own hands by completing everything that is written in the instrument operation instructions.

The motor can stall due to clogged fuel valve. The reason is eliminated by cleaning it. If the lawn mower started up, and then stalled sharply, then it is difficult to supply fuel to the carburetor. Weaken the valves of the carburetor to ensure the free approach of the fuel to it in the right amount.

The Differences Between Petrol and Diesel Engines

With excessive air leaks, the engine may also stall. Add the engine speed so that air bubbles come out faster from the fuel system of the unit. Be sure to check the integrity of the fuel hose. In case of mechanical damage (cracks, punctures, etc.P.), replace the part.

How to clean and store a tool?

During the operation of the lawn mower, monitor the state of the engine cooling system. The channels available in the starter housing, as well as the cylinder ribs, should always be clean. If you ignore this requirement and continue to operate the motorcycle, then you can disable the engine due to overheating.

Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair

Before cleaning, let the engine cool down. Take a brush with a soft pile and clean the outer surface from dirt. Cleaning plastic parts is carried out by solvents, including kerosene, or special detergents.

After the summer season, the lawn mower should be prepared for long.term storage. To do this, the fuel mixture is drained from the tank. Then the engine is launched in order to develop fuel residues in a carburetor. The entire tool is well cleaned of pollution and sent to “hibernation”.

As you can see, it is possible to repair the malfunctions of the household lawn mowed on their own. Service services should be contacted in case of serious breakdowns. In this case, the cost of repairs with the price of a new lawn mower should be correlated. Perhaps it will be more advisable to buy a new tool.

The reasons for the failures of gasoline engines

Gasoline (especially four.stroke) internal combustion engines are designed to operate in areas with a slope of not more than 15 degrees. Short.term 30 degree distortions are allowed. With large inclinations, the motor may stall. A part of the models of the braids has a gas lever: you need to set the ignition on the lawn mower to the maximum before work.

DIY internal combustion engine repair is considered a more difficult occupation than an electric motor. This is due to the greater complexity of its design. You need to know the device of two.stroke and four.stroke engines, their design features.

When starting repair work, you should check the course of the cable of the bracket (lever) of safety. You may need to adjust it.

gasoline, does, twist, disk, damage, details

Fuel mixture problems

The simplest causes of problems with the gasoline unit are the lack of fuel. Its availability is not difficult to check. You should also see the condition and level of oil in four.stroke engines models. If it is contaminated or not enough, then you need to pour a new liquid, draining the old before.

During the constant operation of the mowing, the carburetor is contaminated with fuel combustion products or due to the low quality of the filled gasoline. As a result, the engine speeds swim. You can clean the carburetor node yourself. To do this, it will need to be disassembled and washed with a special tool. You can try initially blowing with air to remove clogs.

It should be remembered that before installation in place, the carburetor adjustment must be adjusted. For the motor to work well, it needs to be correctly configured.

The fuel hose is also clogged with poor quality gasoline. When it does not act, the saloon is cleaned with a needle and replaced by the fuel filter. When the air filter is clogged, the engine power drops. In such cases, the filtration element needs to be cleaned or replaced.

Break of starter cord

Often, starting problems are caused by a break in the starter cord. In the simplest version, the repair of the starter is to connect the rope with the knot. In more difficult situations, you will need to disassemble the entire node and change the cord.

Falf in the spark plug

If the gasoline engine does not start at all or immediately stalls, you should check the spark plug. She must give out a spark, visible even in daylight. To do this, it is twisted and inspected. If there is no spark, then the part is replaced. By the appearance of the candle, you can diagnose a breakdown:

  • If it is dry, then this indicates the presence of a problem in the fuel supply system;
  • When the candle is wet, the malfunction causes the incorrect operation of the carburetor;
  • In the presence of black soot on the candle, it is cleaned or replaced by a new.

Other breakdowns

The gasoline engine works poorly with partial wear or burning of the piston. For the repair, you will need to disassemble the engine and put entire spare parts. Mechanical breakdowns can also occur, for example, jamming of the crankshaft or piston, the appearance of cracks in the carburetor or motor body. In such situations, you will need to install new details.

Serious repair of gasoline engines require professional knowledge and skills. If they are absent, it is better to contact a service center to specialists.

Diagnosis of the cutting part

With the constant operation of the lawn mower, its cutting nozzle is blurred over time. The following signs testifies to this:

  • The grass cover is unevenly mowed;
  • Plants break out with the root;
  • the time spent on work increases;
  • fuel or electricity consumption increases.

When these phenomena appear, the cutting part needs to be inspected and removed if necessary, having previously cleaned the grass trimmers. If there are cracks in the metal or deformation that do not allow the balancing of the blades, then it is necessary to replace the cutting nozzle. Когда износ деталей незначительный, то выполняется заточка ножей. It can be relatively without problems and with your own hands and at home.

To remove a rotary or cylindrical knife, and then sharpen it or install a new one, perform the following preparatory measures:

gasoline, does, twist, disk, damage, details
  • drain oil;
  • Electric lawn mowers are turned off from the supply network, and on gasoline units a button that blocks their power is clamped;
  • From units operating on gasoline, fuel is drained or completely produced, the spark plug is unscrewed;
  • put the mechanism on supports that allow you to get free access to the cutting nozzle.

The latter is only necessary if the internal combustion engine is installed on the tool. You can also tilt this equipment towards the handles, removing the grass collector from it. Models with an electric motor can be repaired in any convenient position.

If there are no special tools that allow the shaft to block, then it is required to do this in another suitable way.

Before work, it is recommended to put on dense gloves to protect your hands from possible cuts about the blade.

The main malfunctions of the gearbox and ways to eliminate them

With a gearbox of an electric or gasoline trimmer for grass, various breakdowns occur. The most frequent of them are presented in the table further. There you can also find the reasons for their occurrence and methods of elimination.

Reducer malfunction Possible causes of breakdown The method of elimination
The gear node is heavily warmed up the use of unsuitable (low.quality) lubrication or its absence you need to replace or add lubricants
The gears are new and did not get sick It should be worked for a short time for a time without strong loads with regular stops so that the mechanism manages to cool
shaking of the shaft during rotation, the appearance of backlash and knocking destruction or significant wear of any of the bearings replace the failed bearing with a new
The transmission mechanism flies from the rod of motorcycles or stagger Damage to its body It is necessary to replace the part
In some cases, with minor damage, a clamp made of metal, a place with a fault is carried out
not fixed on the pipe wear of the docking area you can make a winding from the insulating tape at the mounting site or change the bar
The output shaft with a knife does not rotate or stops in case of an increase in the load wear of the teeth on the gears or one of them It is required to replace the interacting pair of worn details

Bearings are destroyed due to the use of inappropriate lubrication or due to its absence. Their damage is also caused by severe operating conditions of motorcycles and the ingress of extraneous particles of the material (for example, broken metal teeth of mechanical transmissions) due to the fact that the integrity of the anthers is violated.

To remove the bearing, you need to disassemble the gearbox and use a special puller. If it is not, then you can try to do it with a hammer with a mentor. In this case, work should be carefully so as not to damage the seat. Using the pre.heating method to shoot the bearing is not recommended. This is due to the fact that the metal may lose the required operational characteristics.

If the knife ceases to rotate under load or stands still, then this is accompanied by an uncharacteristic sound.

Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.

Gear lubrication of a trimmer for grass

Lubrication of gears must be carried out regularly in accordance with the recommendations set forth in the operational instructions of the model used. You need to do this also if:

In addition to the gearbox, it is also necessary to regularly lubricate the shaft of a trimmer for grass. This is the norm of proper care of the device.

With the constant use of a trimmer for grass, its gear mechanism experiences a load from grass, dirt sticking on knives, or due to a change in torque. Lubricants must be selected high.quality to extend the service life of the gearbox.

Used types of lubrication

When choosing lubrication, it is necessary to take into account the following factors:

Famous manufacturers, for example, STIHL, Husqvarna and others, in addition to trimmers, produce lubrication for them. Such products not only reduces wear, but also protects the metal of gears from corrosion. Therefore, for motorcycle from these brands, it is better to use their lubricants.

If the composition used for lubrication has good adhesion, then it is practically not squeezed out of the gearbox through the gaps.

For different models, lubrication is consumed in different ways. This is determined largely by the intensity of the use of motorcycles and heating the transmission mechanism. It is believed that the lubricant is enough if the temperature of the gearbox during operation does not exceed 40 ° C.

By consistency, lubricants for a trimmer for grass can be:

In terms of composition, the following types of lubricants are in demand:

  • graphite, significantly reducing friction, as a result of which the rotation of the gear improves;
  • lithium, which are also an excellent anti.corrosion composition, saturated with increasing the wear resistance of metal with additives without harmful substances;
  • universal, containing mineral oils and improving operational characteristics components.

An example of suitable lubricants are: Champion EP-0, Gear Grease Oregon, Oleo-Mas, Azmol 158, Litol.24. You should also pay attention to the advice of manufacturers on this issue and use the materials they offer. You can buy them at specialized retail outlets.

A lubricant Champion EP-0 Universal 120 gr

The algorithm for self.lubrication of the gearbox

To make lubrication of the gear ratio, its preliminary disassembly is not needed. A special hole for these purposes has already been laid in the device (it is shown in the photo below). In addition to gears, when lubrication, you need to pay attention to such elements of the mechanism:

Pour oil or apply solid grease through a tavniper closed by a screw. At the same time, they perform actions in the following sequence:

  • The gearbox body is cleaned of dirt and adhering grass, especially thoroughly the plot around the plug so that the garbage does not get inside the mechanism;
  • Using the appropriate tool (often it comes with a trimmer), the cork is unscrewed;
  • The selected lubricant is introduced from the tube into the open technological hole, or using the syringe, as shown in the photo further;
  • screw the cork in place.

When making lubrication, you need to rotate the knife so that it is evenly distributed through the teeth of moving gears.

If for any reason the gearbox needs to be disassembled, then the old lubricant must be completely removed from the entire surface of the gears and housing, shaft, and only then use the new. The disassembled mechanism is conveniently lubricated with solid compositions.

The entire reducer lubrication process is demonstrated in the video:

Lubricating the gear node is required at least once during the year, but it is recommended to do this every 20 hours of intensive use of motorcycles. If the first signs of malfunctions with the mechanism appear, then you need to make lubricants as quickly as possible.

How to remove the coil and replace the fishing line for the trimmer

The owners of the trimmers, mainly beginners, confuse, bordering on panic, when it becomes necessary to change the cutting tool or fishing line for a trimmer in a reel. Very often, when trying to unscrew the mowing head, users simply make it unusable, not suspecting that it is unscrewed in the opposite direction. So that this does not happen, if you need to replace the tool, it is recommended to familiarize yourself with the instructions given below.

  • Before refueling the fishing line for the trimmer to the coil, drown out the engine of motorcycles or de.energize the ethletric trimmer for the grass to avoid injuries that may occur in case of accidental rotation of the cutting tool.
  • Unscrew the nozzle mounted on the gearbox shaft. To do this, the shaft must be fixed by combining holes on the puck and on the axis, and inserting a metal rod or screwdriver into them.
  • Unscrew the nozzle. You should know that the thread on the shaft is left. Therefore, to twist the coil of the trimmer for the grass should be right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the fixers. To remove it, you need to drown these latches into the case, pressing the edges of the lid. If your trimmer has a semi.automatic mowing head, which has a button from below, then disassembling the nozzle should be done carefully, since you can lose a spring that sometimes flies away when removing the cover.
  • Cut the required amount of fishing line. Usually its length is 5 meters. Use the cord of the diameter that is indicated in the instructions for the tool. It is not recommended to exceed the maximum diameter of the fishing line, since this will lead to increased load on the engine and greater consumption of gasoline.
  • Find the middle of the segment of the cord, folding it in half. You will get a loop.
  • Special grooves are cut out inside the coil (there may be holes). Insert the loop from the fishing line into this groove.
  • Wind a fishing line for a trimmer to a coil, turning it counterclockwise. You need to refuel the cord as evenly as possible, the turns should be laid without ceiling and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the coil.
  • Collect the braid head. Before you finally collect the nozzle, do not forget to insert a spring and washer (if it is available). Install the coil in the case, and prone the ends of the cord through the holes or eye.
  • Dress the lid and fix it with latches.
  • Screw the nozzle back to the gear shaft, also fixing it with a screwdriver. Tighten the coil of the trimmer for the grass will need to go to the left (against h. Arrows).

Is it possible to make a coil for a trimmer for the grass with your own hands

On sale there are a large number of trimmer heads (not automatic), which have a low price and good quality. But sometimes situations arise, for example, in the country, when the trimmer coil broke, and its repair is impossible, the store is far away, and you need to mow. In this case, you can quickly, literally in a few minutes, make a simple trimmer nozzle to fix the fishing line from ordinary plywood 10-12 mm thick.

  • Take a piece of plywood or textolite and draw a circle with a diameter of about 14 cm on it.
  • Cut the disk with a jigsaw or hacksaw for metal.
  • Drill a hole in the center of the disk, suitable in diameter to the gear shaft. Do not forget before installing a disk on the shaft, put a puck on it.
  • You can fasten small corners along the edges of the disk or make 1-2 holes on the opposite sides. They will serve for refueling fishing lines in them.
  • To fix the fishing line for a trimmer, you can screw several screws into the plywood.

Such a homemade mowing nozzle is fixed on the shaft with a nut. Twist or unscrew the nut without fixing the shaft will not work. To replace the cord, it will be enough to release the screws, insert a segment of the fishing line of the required length and press it again.

Also, a mowing nozzle for fixing the fishing line on it can be made from a metal sheet. How to do this can be understood from the next video.
