How to change protection on a trimmer. Electric trimmer diagram for grass: what to pay attention to when faults occur

The causes of breakdowns of gasoline and electric trimmers

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

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:

GreenWorks Cordless 20V 12-Inch String Trimmer Review

  • 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.

How to put a knife on a trimmer for grass correctly

Putting a knife on a trimmer for grass is not so difficult. The manufacturer equips his tools with a special pin that allows you to block the gearbox and the key, with which the spool is unscrewed with the fishing line. The most important thing is to observe when changing the cutting elements safety precautions and the assembly sequence of disassembly.

The algorithm for installing a knife on a trimmer for the grass is as follows:

  • Remove the protective casing;
  • We block the drive. To do this, you need to combine two holes. in the shaft hub and in the gearbox cup. After combining them, insert the pin into the holes;
  • We unscrew clockwise a spool with a fishing rod with a fishing line or a mounting nut that holds the boot (if the trimmer for the grass has not yet been used);
  • Next, we install the cutting knife, so that the slots on the puck of the hub coincide with the notchs in the hole of the cutting disk;
  • Install the boot;
  • We twist the mounting nut (counterclockwise) holding the stopped pin;
  • We tighten it using a tubular key;
  • Return the protective casing in place.

Abstract for the maintenance of gasoline trimmers and motorcycle

Nozzles for trimmers can be the simplest (head with a fishing line), but there are options that combine several functions. Their cost is much larger, but also efficiency higher.

Makita KR400MP

The cutting element is made up of cutters made of high.quality metal in a diameter of 23.2 cm. The main advantage is relatively low, which allows you to work on the site for more than an hour without stopping to rest.

The brand has proven itself well, so such a cultivator.type nozzle is the highest quality and comfortable to use.

Oleo-Mac Cult

The nozzle has a soil lug, thanks to which you can set the desired depth of plowing. The rohs of weeds cling to the knives and stretch to the surface of the soil. Suitable for weeding a row, greenhouses and gardens of large areas.

Relatively large dimensions, which several times weights the weight of the trimmer itself for grass.

SRAC-2500 Echo

A trimmer nozzle for grass, which simultaneously removes weeds and loosen the soil. Is one of the most affordable options among itself. Average

  • Compact, easily passes near plantings, without injuring their underground part.
  • Quality components.
  • Long life.

It is necessary to independently adjust the depth of cultivation at the level of 1-2 cm

According to buyers, it was this nozzle that showed itself well in the front garden, and in the greenhouse, and in the open field.

What knives to put on an electric and a lawn mower

Before buying and putting a knife on a motorcycle, find out what they are and in what cases are used. Today, manufacturers offer the consumer a large number of types of these supplies. In general, the entire cutting tool designed for mowing grass can be classified:

The main material for the manufacture of trimmer knives can be plastic or metal. The use of such consumables largely depends on two parameters:

For safety reasons, manufacturers do not recommend putting steel knives on electric trimmers for grass. Almost all motokos operating from the electric network and battery are equipped with plastic blades. Depending on the manufacturer, they can be a solid disk design, with several blades or in the form of a special mowing head, which provides for the installation of removable plastic blades.

Direct rod in a gasoline trimmer for grass and curved in electric

Putting a metal knife on an electric trimmer for grass does not allow its design features.

  • The curved rod of the unit reduces the distance from its working part to the legs of the Kosar. In the case of a collision of blades with a stone or other hard object of a braid for grass, it is discarded to the legs.
  • The high torque, which we mentioned above, in the event of a collision of a metal knife with a solid object, transfers a large load to the flexible shaft of a trimmer for grass and its engine. What causes their premature failure.
  • Handle Electric Knules most often does not have a restrictive bar playing the role of the stop. Which does not exclude leg injury.

It is these features that allow the use of exclusively plastic knives on trimmers with electric engines. In a collision with an obstacle, the blades are destroyed, thereby protecting the legs of the mower from obtaining possible injuries.

Plastic knives cope well with outgrown and dry grass. They can mow the nettles and stems of burdocks.

The use of metal knives only on gasoline trimmers is also due to constructive features.

  • The direct design of the rod increases the distance to the legs, which provides the Cossacks with complete safety.
  • Comfortable U-shaped and J-shaped handles allow you to keep the tool firmly. D-shaped handles Motokos are equipped with a limiter resting in the leg of the Costsa, which does not allow to let the head to the legs when meeting a cutting disk with a solid obstacle.
  • The clutch of the gasoline engine allows you to smoothly gain speed to the optimal level. And when the blade collides against a hard surface, it can extinguish part of the blow.

Thus, gasoline trimmers for grass with an installed metal knife are best used in large areas. They will successfully cope not only with high coarse grass, weeds, burdocks and nettles, but also with shrubs, as well as young trees.

The shape of the blades of the disk set to the trimmer for the grass does not affect the quality of the work performed. The speed does not depend on them. Triangular, trapezoid, rectangular forms are all marketing course of manufacturers.

If you plan to prepare hay, then it is best to put knives on a motorcycle with a large number of blades. Pay attention to the wheels with eight teeth or discs with four large blades and four additional. Two and three lobed knives will greatly grind the grass.

Fuel mixture

-high-quality two-stroke oil for reserved equipment (10-15 thousand. about./min., about 200 vol./sec.). Do not use motorcycle oils (small engine speed) or for aqua technology (other cooling system). their implementation does not provide the necessary lubrication of the piston group and parts of the entire motor! Gasoline-at least some unsuccessful high-octane gasoline (with the number of 92 and above, with a density within the boundaries of 750-770 kg/m3). The proportion of the fuel mixture is 1:50 (2%) or 20 ml/cm3 of oil per 1 l of gasoline. For example, pour half a gasoline measure into a transparent plastic bottle (1 l), then make a honey with a syringe (20 ml/cm3) and mix, add gasoline and mix painstakingly. If the quality of gasoline is incomprehensible or the working conditions are difficult, then the amount of oil should be increased to 22-25 ml/cm3. Before each refueling, shake the mixture. Having made a protective casing (how to install on a protective casing and on a trimmer. Replacing fishing line on a trimmer How to install a spitter and knife on a trimmer for grass. Store the acquired fuel less than 2 weeks. If the color of the consistency has changed (from the color of the sea wave, for example, Karim has become), then it is not recommended to use it.

With the advent of the summer of many owners of personal plots, the question is disturbed by a knitted one with how to put a knife on a trimmer for grass.

The questions are no less relevant why and when it is advisable to replace the fishing line for the trimmer on the motorcycle with a more durable cutting element. The trimmer set for the grass OLEO-MAC TR 130 E includes a mowing disk with a trimmer for the grass is simple with an oblique.

In our article, we will try to disassemble all this and give useful recommendations to summer residents.

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 a thick 23 mm cord or homemade rods with cables makes vegetation wind up on a spool. This increases the load on the engine.

As a result, the piston group and other mobile units of the unit wear out very quickly.

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.

Before buying and putting a knife on a motorcycle, find out what they are and in what cases are used. Today, manufacturers offer the consumer a large number of types of these supplies. In general, the entire cutting tool designed for mowing grass can be classified:

Types and principle of the filters for a trimmer for grass

In modern motorcycles, two types of filters are used. fuel and air.

Even the highest quality fuel has various additives that quickly accumulate and disable the technique.

The task of the fuel filter in gasoline trimmers is to protect the device engine from various impurities contained in gasoline and oil.

Outwardly it is very small in size. Make it from felt material. A compactly folded felt manufacturer placed in a metal tip and has on a fuel tank on a fence tube.

Another placement option is in the highway between the carburetor and the tank. Many owners of trimmers note even excessively thorough cleaning, so the material is quickly clogged so much that it requires a complete replacement.

Original consumables can be purchased in specialized stores. Average apiece.

Its main purpose is to keep the dirt and dust entering a trimmer for grass grass during operation.

With mowing, not only dust rises into the air, but also a small SOR, crushed grass, which can quickly clog the technique. A good filter will prevent engine breakdown, even if the air is very contaminated.

The place of its location can vary depending on the model of the trimmer for the grass, but is usually located on the side of the device under the protective casing.

The casing is fixed either on a bolt or latches, which are very easy to open to remove the contents. The filter itself can be made in the form of a ring or plate of foam, felt, fleece.

If you mow on average 1-2 times a week, then it will be enough to replace at least once a year. With more intense use, check and replacement should be carried out more often.

Modeling recommendations

Do not immediately, filling the mixture, go into a difficult fight with thick vegetation. It is necessary to start with the run.in, which will help to develop moving parts to each other and strengthen the skills with the device.

  • Do not immediately run the engine for maximum speed. It is best to dwell on the maximum torque moment.
  • Overheating is not allowed. However, you can’t mow on an unheated engine too!
  • The engine cannot be overloaded. The throttle should be opened by 2/3 of the course.
  • After running in, the oil drains.

These rules will allow an increased lubrication of parts of the piston group, which will become a guarantor of a long operation of the entire device.

The main malfunctions of the coil

Users of the electrimmer and lawn mower often face a problem associated with a semi.automatic braid head. Coil malfunctions can be as follows:

How to Fix a Trimmer That Won’t Start!

The fishing line for the trimmer does not extend automatically

If, with a light blow, the trimmer coil button for grass on the ground is not lengthened for a trimmer, then the reasons for this may be the following.

Option 1. there was a snack, t.e. Squeezing the cord between turns. This problem usually appears if the user wound a fishing line for a trimmer to the coil unevenly, with the intersection of the turns, or wound it with insufficient tension. In the latter case, when the mowing head is rotated at large revolutions under the influence of centrifugal force, the cord begins to drag on, as a result of which the interitral clamping of the fishing line is possible. To eliminate the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, even turns with good tension.

Option 2. too short ends protrude from the head. A fishing line for a trimmer may not exit when hitting the ground, if its ends sticking out of the head, insufficient length (short). In this case, the centrifugal force is not enough for the fishing line for the trimmer to stretch. Therefore, it is required to stop the unit (drown out the engine or turn off the ethletric trimmer for grass from the network) and pull the fishing line for the trimmer manually, after pressing the button.

Option 3. a fishing line for a trimmer was soldered inside a mowing head. This leads to the fact that the coil is stopped and does not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil with prolonged operation of the unit, a fishing line on solid items.

  • In the first case, the cord of third.party manufacturers can be made of low.quality and fusible materials that do not withstand the mechanical and temperature load. Therefore, preference should be given to “branded” fishing.
  • But, if you still purchased a fishing line for a trimmer of unknown quality, and it is often soldered during operation, then you can follow the example of some users who, after refueling the cord, moisten it either with silicone grease (from the spray can), or mineral oil). This procedure greatly reduces the likelihood of soldering a fishing line among themselves.
  • Also, a fishing line for a trimmer can sleep if during a mowing it hit a hard object (stone, fence, dry branch, etc.D.). As a result of this, it is slightly stretched and draws back into the head with high speed. The cord is heated from friction, and its turns are sticking together. The only thing that can be done to eliminate this malfunction is to open a trimmer coil for grass and rewind a fishing line for a trimmer.

The cord spontaneously lengthens

There are situations when a user of a trimmer for grass notices a very fast fishing line consumption. At the same time, he never hit the ground with a button to lengthen the fishing line. The reason that the fishing line for a trimmer spontaneously lengthens, cutting off a special knife on the casing of the device, may be the absence of a spring in a mowing head. Often beginner users of mowers, trying to charge a fishing line for a trimmer into a coil, forget to install a clamping spring in the head, or completely lose it when opening the lid, and in the future, they do not even suspect its existence.

Also, a fishing line for a trimmer can lengthen without using a button if the spring is weakened. If the spring check confirmed this fact, then it is necessary to put several goals under it to strengthen its clamping properties.

The kinematic scheme of the trimmer for grass: how the torque is transmitted from the engine to the mowing head. where the breakdown occurs

The electric trimmer for grass with the upper location of the engine, like gasoline, has two designs for transmitting torque through a bar with a shape:

Right.line bar is used on more powerful and expensive trimmers. I have a more budget option, but it works reliably. I’ll start the description with him.

The upper part of the rod is inserted into the case. It is fixed by fasteners from the opposite sides. two diametrically located.

A hole for a self.tapping screw

A spring shaft rotates inside it, the free end of which is inserted into the transition bushing.

Shaft fastening

The rotation is transmitted directly. On powerful trimmers, an upper gearbox can stand here, which increases the power of effort due to the number of revolutions, so necessary for the kosba shrubs and young trunks.

Personal opinion: it is better to saw wood with a saw. not a trimmer with an electric motor or gasoline engine.

I have a collapsible barbell. Consists of two parts, which allows you to transport an electric cost in the cabin of an ordinary car.

Marketers consider this a useful function, but for 6 years I have never used it, except for the case of disassembly to show you with this design by photography.

The possibilities of bending the spring even under its own weight are clearly visible below.

I draw your attention to the fact that it should always have a special lubricant. It sharply reduces the possible force of shaft friction on the internal walls of the metal pipe, eliminates its damage.

The second shaft, located sequentially lower, is completely the same. But he needs a lubricant to a greater extent: he works inside a curved tube and should be better lubricated.

The shaft enters the sliding bearing mounted inside the lower part of the bar. A coil with a fishing line is fixed at the lower end.

By the way, an electric motor of 800 watts and a 1.6 mm fishing line on a trimmer is quite enough for regular mowing of grass around a summer residence. The power of the lawn mower of 1.85 kW and the thickness of the fishing line 2.4 mm for my purposes is excessive. Although the work goes faster.

Parts for fastening the coil with a fishing line on the output shaft showing the next picture.

The factory coil by the end of the sixth season of operation, I wiped on the ground to the base, and the fishing line for the trimmer completely cut out metal bushings and crawled out of its plastic walls.

I tried to carry out its repair, but this is not effective: useless activity. The picture is already a second, purchased coil with a fishing line of my braid.

Sliding bearing (when there are no balls or rollers, but simply a calibrated hole in the sleeve is made) is far from the best technical solution. I have already worn out on a trimmer and requires replacement.

There are practically no such bushings on sale. It is necessary to remove them and order from the turner.

On the Yandex Dzen channel, I show the phased replacement of the fishing line inside the coil in the form of a narrative.

Features of the design of trimmers with a straightforward bar

The rotation of the electric motor inside the bar is transmitted by a continuous shaft, not spring: more reliable when working. It can be one or consist of two parts, which allows you to better transport the assembled ectric trimmer for grass.

Rolling bearings work on continuous shafts, and this significantly prolongs the overhaul period and the resource of the product.

A trimmer for grass with a rectilinear bar can have an upper gearbox, joined with an electric motor shaft. Gears in it are cylindrical.

An alternative option is the lower location of the gearbox with the release of the rotating moment directly to the mowing head: conical genees.

Any design of the gearbox transfers rotation with gears and requires their lubrication. Without it, friction increases dramatically and, as a result, the wear of the mechanism increases: a short time will work.

To lubricate a trimmer gearbox, use only special trimmer lubrication varieties: they work better.

I do not use a cutting disk for mowing bushes on my benzos, and it is not on an electric trimmer. Therefore, I do not publish any information about his work.

I will end my article on this. The remaining details of the trimmer for grass, in my opinion, break less often and do not require complicated repair, like belt equipment. For example, I just replaced a broken buckle with a piece of wire hit.

I want to offer you to participate in a short survey and express a personal opinion that will help the next readers of the site.

An interesting solution for the repair of Elektokos is offered by Malusha in its short video, refusing to install the smooth start of the engine. Do you consider such a decision justified?

Another useful video relates to the elimination of increased vibration of a trimmer for grass. Masterlom solved this issue independently and original: changed the size of the thread, an additional adjustment was carried out.

If you have not yet found out questions about Motokos, then use the commentary section. Now it is most convenient for you to do this. I’ll definitely give an answer.
