Setting a spring on the Patriot trimmer. Other malfunctions

Electric trimmer for the grass Patriot 1000 how to remove the coil

If your coil is designed to work with only one osmus, then everything is simple here. It is necessary to rewind 2-4 m of fishing line (depending on the size of the coil), find the hole for the trimmer on the inside of the coil, insert one end of the fishing line there and start to wind the fishing line for the trimmer in the direction in the reverse direction of rotation of the coil at the trimmer. The inside of the coil is usually indicated with an arrow in which the side is to wind a fishing line for a trimmer. Having wiped a fishing line for a trimmer, we leave its small piece unnecessary to put it out. We fix this piece in a special groove located on the inner part of the coil and designed so that at the time of collecting the coil of the fishing line for a trimmer does not unwind. If there is no such groove, then you will have to hold a fishing line for a trimmer with a finger, so as not to let it unwind during the further collection of the coil. Next, we take the outer part of the coil and spread the outer piece of fishing line into the available hole, collect and put the coil back to the trimmer for the grass.

If the coil is designed to work with two antennae, then we do the following. On the inside of the coil, we look at how many grooves are available for winding fishing. There may be one or two of them. If the groove is one, then both antennae are wound on this one groove. If there are two grooves, then each antennae is wound in a groove. The coil with one groove should have a through hole in which a fishing line for a trimmer is threaded. We open 2-4 m of fishing line, we extend it through this hole so that on each side of the fishing line it sticks the same. And we will simultaneously wrap both the antennae of the fishing line in one direction, the reverse direction of rotation of the coil in the trimmer and coinciding with the direction indicated by the arrow available on the inner part of the coil. We leave a little fishing fishing line, we fix the resulting ends in special grooves, and if they are not, we hold with your fingers. We spread both ends into the available holes on the outer body of the coil. Collect the coil and fasten it to the trimmer.

In the presence of two grooves, a piece of fishing line 2-4 m long is folded in half, we insert the loop in the groove between two grooves at the bending site, and we wind both the ends of the fishing line each in its groove at the same time. Further actions are similar to the previous option.

There are also coils, in which a fishing line for a trimmer is threaded through a through hole on the inside. After that, the ends of the fishing line, without wrapping, spread completely through the holes on the outer body of the coil, collect the coil and begin to rotate the button that is usually pressed in order to release the fishing line for the trimmer while it is worn out. Rotate the button. inside the trimmer fishing line is wound itself. At the same time, it will not work to twist it in the “wrong” direction, since it can spin only in one direction. If you get used to it, then you can wrap a fishing line for a trimmer to such a reel without even taking it out. you just need to combine the through hole of the internal drum with holes on the outer body of the coil, and then pass the fishing line for the trimmer in them.

That’s all on this issue. Successful winding!

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.

How to remove or refuel a fishing line for a trimmer in a trimmer for grass

In order to wind a fishing line for a trimmer, it will take about 10-15 minutes. What is the coil of a trimmer for grass? Plastic case with a cassette inside, on which there is a special hook for convenient winding of fishing line.

Almost all the coils of the trimmers have a similar attachment principle, this is a central screw-button, when pressed, it becomes possible to stretch the fishing line for the trimmer of the required length. The photo below shows several examples of various coils for trimmers.

Bobbins of the trimmers, the motor of which is located near the ground, have a different fastening to the rotation axis, they have two buttons on the coil located on the sides that need to be squeezed, the rest of the thread is no different from the other cassettes.

The principle of proper winding of the fishing line is similar in all of the above cases, so for example, consider the standard option with two antennae.

To remove the coil with a fishing line, you must unscrew the screw in the center, but keep in mind, the thread there is left, so you will have to twist clockwise, it is specially so that it does not open under the influence of centrifugal force during operation.

Next, using the screwdriver, disassemble the head and remove the coil, on which the fishing line for the trimmer is directly wound.

Having measured the required length and folding it in half, you need to tuck a fishing line for a trimmer into a coil, bringing it out, as a result, its ends opposite each other (for this there are special slots for fixation).

After that, it is necessary to assemble the head in the reverse order, passing the ends of the cord in two corresponding holes.

If there are doubts or it is not entirely clear how to charge a fishing line for a trimmer for a trimmer for grass recommend that you see how to correct the fishing line for a trimmer into a lawn mower.

In this video, the instructor will open a trimmer head in detail by steps, it will measure the required amount of fishing line, as a rule, this is from two to four meters, and demonstrate the assembly and installation for a trimmer for the grass.

How to replace or put a starter spring in place?

If everything turned out to be in order with the rope at the starter, the suspicion falls on the coil itself. It is driven by a strip spring rolled into a roll. To change the spring, certain steps should be taken.

  • Remove the starter from the lawn mower.
  • Remove the starter coil.
  • Unscrew the main bolt holding the pulley on the case.
  • Pull the exciting antennae and the spring, the strip spring is almost completely straightened or folded by rings of a larger diameter.
  • Hold it in advance.
  • Check if the spring is valid (there may be rusty stains, breaks, etc. D.). If the hooks at its ends are cut off, the new ones will not be bent. high.carbon steel breaks when trying to bend it. Weakened hooks are suitable for easy bending.
  • Make sure that an auxiliary (ordinary) spring with washers in place. These details protect the coil frame from the end of the main spring with the ends. If the washers and the spring are broken, but there are no new ones, do not screw the coil bolt hard, but follow it. it can unscrew and get lost.
  • If the main (flat) spring is damaged, insert the same new. Put the hook at the end of the spring in its place and bend it, inserting the turn behind the turn into the space where it should be and should be.

The rewinding of the spring is performed in a minute. Oknovka in this action is gained quickly.

How to replace or put a starter spring in place, watch in the next video.

Dismantling, disassembling the starter of a trimmer for grass, replacing parts

First of all, the repair process begins with the removal from the trimmer for the grass of the entire starter. This process is inherently not difficult and will only require twisting several screws with a suitable locksmith tool. It should be noted that when dismantling the mechanism of launching the lawn mower, it is necessary to observe safety precautions, since the strip spring in a compressed state has sufficient energy to injure a person.

Parsing the starter motorcycles

This stage allows the master to establish the reasons for the failure of the launch unit, as well as to defect individual parts. The disassembly work should be performed in the following sequence:

Eliminated spring from a starter coil

Many experts note that the first time the installation of the spring is quite difficult, because the owner when repairing the starter of the trimmer for the grass will need not only the basic skills of the locksmith, but also patience.

The sequence of assembly of the starter of the trimmer for grass

Although the process of assembling the launch unit of the lawn mower is carried out in the reverse analysis of the order, there are several nuances that should be paid special attention to:

  • The coil with the spring installed must be turned and mounted in the groove of the starter case so that all the protrusions become in their original place.

Installation of a trimmer coil for grass in the starter case

When assembling the starter, pay attention to the compression spring, which on both sides should be limited by steel springs. If this is not done, then after the first season it will rub the grooves in the pulley case

Recommendations for stretching the strip spring

After installing the starter, it is necessary to dismantle the rope handle and insert it into the groove of the coil. Further, against the move of the pulley when starting, it is necessary to make a certain number of revolutions specified in the operation of the gasoline trimmer for the grass. It is worth noting that on how to put the spring on the trimmer and how the tension will make the tension and further performance of the node depend. At the final stage, we spread the rope into a special hole and fix it with a handle.

Replacing the rope of the starter of the trimmer for grass

At the very beginning, it is necessary to extract a broken cord, select a suitable length depending on the trimmer model for the grass. We extend through a special hole in the pulley and at the other end we tie a knot in order to prevent jumping out the rope from the trimmer starting mechanism for grass. Next, we build a strip spring to the required number of revolutions and mount the handle.

One of the key nodes of the lawn mower is a starter designed to simplify the start of the device engine. Like other details, it breaks periodically. In this case, there are two solutions to the problem: repair of the starter of the trimmer for grass or its complete replacement. The second option is simpler, but expensive. In addition, the required detail first needs to be found on sale, since different starters are used for different models of gasoline. In the presence of free time and screwdriver with a suitable tip, restore the performance of this node yourself, if you know how it works, what malfunctions are characteristic of it, and how to eliminate them correctly. About all this. in this material.

How to tighten the starter spring chainsaw

A chain starter. Learn to repair yourself

For the quick launch of any chainsaw, a starter is required. Когда коленчатый вал инструмента ускоряется, топливно-воздушная смесь, подаваемая в двигатель, сжимается, а не его дальнейшее воспламенение. How to replace the spring. Details of replacement of a chainsaw with a dog starter, how to tighten. Therefore, the normal work of the starter for the chainsaw determines the effectiveness of the entire mechanism.

The device of the chainsaw starter

The principle of operation of the starter for the chainsaw is as follows. The handle is inserted into the groove of the case through which the cable passes. The principle of the starter for the chainsaw is how to put the spring on the starter. If the handle is sharply raised, the cable stretches and combs the rattle drum, which transfers movement to the drum with slots provided for the shaft. At the same time, the crankshaft makes several revolutions, and the working mixture in the space between the pistons does not compress the cylinder head. Accordingly, when the handle is lowered, the contact between the ratchet is not lost by hairpins, the shaft does not stop.

As the engine volume increases, the amount of unnecessary fuel mixture necessary for its subsequent ignition increases, so the number of jerks of the starting cable for saws of high power increases. Therefore, in order to speed up the return of the drum, the springs of a forced return made of steels with high elastic properties are used.

Simplification of the launch of the chainsaw is carried out in the following ways:

  • By preliminary enrichment of the working mixture, for which a special damper is installed in the design of the carburetor.
  • Installation of an automatic decompression valve, which lowers the operating pressure in the chainsaw cylinder.
  • Installation of an additional spring that, when the cable moves, facilitates the unwinding of the crankshaft.
  • The presence of some chainsaws (nettles, series Partner S, Maxcut, etc.) In the design of the primer. a pump that provides preliminary fuel pumping.

Chainsaw repair, starter

With frequent launches, the chainsaws are constantly subjected to dynamic loads from the chainsaw. As a result, the cable may burst, several rattles of the ratchet will crumble, and the shaft will return with a much lower speed. Therefore, checking and even starter repair. These are operations that are sometimes performed several times during the season.

Replacement of the cord

When stretching, there is a constant friction of the cable around the starter case

To replace the assembly, the assembly is disassembled and the rattling drum carefully rises so that the spring does not jump out of the nests. It is best to do this work together: the assistant blocks the spring, and the cable is replaced

How to pull a spring starter spring on a chainsaw, repairing a chainsaw starter. After attaching the cable, the cable is wound on the roller to the handle and grooves of the drum and the case is assembled.

Spring repair

If the spring material is bad, the spring bursts (usually at the place of fastening to the drum where the loop is formed). In this case, there is no need to replace the spring. It is enough to carefully clean the surface of dirt and traces of lubrication, thoroughly polish the destruction place, and then release the spring at a temperature of 600. 650 ° C (spring steel should become raspberry). You need to slowly cool the spring, but at 100

150 ° C can already carefully turn its end in the form of a limiting protrusion on the inner surface of the drum (steel acquires the necessary plasticity) and put it in place. Easy repair of the chainsaw, repair of the starter chainsaw, how to tighten the valve correctly

The elastic properties of the spring will not change.

How to put a spring on a starter chainsaw?

Inserting the starter spring into the desired groove is not easy even for an experienced user. First, the spring should be twisted to the previous diameter and inserted into the drum hub. The outer end of the spring is fixed with a restrictive protrusion, and the outer end should be located opposite the hole in the lock using a screwdriver. The hinge on the inner end of the spring is combined with a screwdriver and the disk is lowered. Disc rotation checks whether the ratchet mechanism has been installed. Next comes the rattle itself.

After installing the spring, adjust the spring. How to tighten the starter spring, tighten the spring. Starter handle how. To do this, a cable is inserted into the groove in a circle, and a return spring is spinning around it. After removing the cone, it is better to wind the spring at a few more revolutions to ensure the required tightness of the workpiece.

How to tighten the shutter spring?

In fact, several springs are included in the design of the roller. The first spring is part of the element that attaches the canvas to the shaft. It does not need to be configured, since it provides only the uninterrupted operation of the Internet and the suppression of its inertia. The second spring is the main element of the so-called PIM (the mechanism of the spring-inertial shutter), which provides a quick and uniform lifting of the canvas.

The essence of the PIM spring adjustment is to control the rotation that it performs when lifting the canvas. As a result, the rise rate is adjustable, and the length of the canvas is adjustable, that is, the number of planks necessary to completely close the hole.

The larger the number of revolutions, the spring is twisted. the greater the power of its promotion. and the higher the speed of lifting the canvas. However, one should not strive to ensure that the strips literally take off (more precisely, fly) into the box. restrictions on the lower strips do not support this.

PIM spring tension

The spring is pulled when the canvas is put on the drum. The voltage and adjustment of the PWM are performed according to the following algorithm:

  • traction springs worn on the canvas (included);
  • The spring mechanism is put forward (the number of revolutions depends on the diameter of the shaft and the overall size of the canvas. An approximate number of revolutions can be found in a special table);
  • The spring is fixed with special brackets;
  • The springs of the thrust are covered in the shaft in special slots located at its ends;
  • a spring stop is removed;
  • The smoothness and speed of the blade is checked (it is necessary to hold it with your hand to prevent sharp strokes of the plugs on the lower plate along the edge of the box, and if the plugs are not installed, avoid complete winding of the canvas on the shaft).

Speed ​​control

We have already stated that the number of PIM spring turns depends on the sample parameters such as the shaft diameter and the weight of the canvas, as well as its length in the detailed state. With the primary winding, special accuracy is not required. All you need to do is enter the interval indicated by the spring of your chosen model and the diameter of the shaft in your damper. However, further revision should be carried out with special care.

To reduce or increase the speed, it is necessary to remove the blade from the shaft by removing the traction springs from the penetration on it. Before applying a spring on the canvas, as in the first case, it is fixed using a holding bracket.

How to make a high.quality fuel mixture

  • Gasoline is poured into the tank to the corresponding mark.
  • Two.stroke engine oil is poured into gasoline, and not vice versa, to the level of the mark
  • The mixture is shaken several times until a homogeneous substance is obtained.
  • If there is no special container in the package, use a regular gas cylinder. Fold the mixture in this ratio of gasoline / oil 32: 1.
  • It is not recommended to prepare the mixture directly in the fuel tank of the trimmer for grass.

At the very beginning, the technical condition is being tested:

  • The hinges of levers, ball supports, shock absorbers on VAZ 2107 and springs are being examined. If there are no visible defects in components of the elements, the lifting of the vehicle is debugged.
  • Then the support bearing is checked for the presence of gaps.
  • After the silent blocks of the rubber.metallic type are checked.
  • The lower ball supports are diagnosed.
  • An inspection of the stability stability of the transverse direction is carried out. It should not have any cracks, no scratches, no other damage to mechanical origin. Drying bushings and damaged brackets are not considered a format.
  • The pair of the front shock absorber is checked.
  • The state of the front springs is studied.

Starter repair work

Problems in the work of the starter may not ensure the launch of the tool. That is, after the cord is stretched, the chainsaw does not start to work.

Family Brovchenko. Springing a spring in a hand starter of a lawn mower.

How to install a spring in a hand starter for a benzo-trimer? At home it is possible to do it. to me.

Before you repair the starter, you need to prepare the tools with which work:

  • set of screwdrivers or a special tool that is attached to the manufacturer complete with the tool;
  • a rope that will be used as a replacement of a broken cord if necessary.

A large amount of black carrier on the spark plug indicates the violations in the engine operation.

Before proceeding directly to the repair of the starter and clarifying the causes of malfunctions, it is necessary to remove it from the tool body. To do this, unscrew several screws holding the side cover to which the starter is attached. Problem with the installation of the Stihl 38 lawn mower starter. This is done by a screwdriver or a specialized tool.

After the lid is unscrewed, it is turned over and examined. Next, unscrew the screw with which the starter is fixed. After that, the clamp and the spring are dismantled to carry out smooth launch. Now for removing it is accessible to an affordable pulley on which the cord is wound. After the knot on the rope is unleashed, it can be pulled out of the pulley and replaced with a new. Provided that the loss of performance of the starter is associated with the cliff, this may be enough to eliminate the breakdown. Launcher. However, the rest that make up this element of the chainsaw should be carefully examined.

When examining the components of the starter, the following malfunctions can be identified:

spring, patriot, trimmer, other, malfunctions

Most often, damage to the smooth starting spring occurs from the end where it is visible when disassembling the case.

  • The pulley can be damaged. It is possible to have cracks or tears, as well as damage on the back. As a result of these problems, the tool cannot perform work.
  • Damage to a smooth launch spring. The device of the starter of the Lawn mower Interskol ICD 4325. In this case, it can be mechanically faulty both the spring itself, and there are defects in the place of its fastening. The weakest place of this element is precisely the fastener and the tip of the spring, which is inserted into it.

If faulty or partially damaged starter parts are detected, they must be replaced by new. In this case, new elements must correspond to the repair model of the saw.

After the repair is completed, it is required to properly assemble the starter.

The pulley is installed on top of the spring. At the same time, it is necessary to check how much they clung to each other. During the repair, it is necessary to perform the pulley winding. This must be done in such a way that when rotation, he pulls the cord into the starter. It is enough to make 3-4 turns to give the required voltage. Replacing the starter of the lawn mowed. Previously, the rope is threaded through the hole in the chainsaw cover.

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.

The manufacturer made sure that the load created by the tool was distributed evenly to the body. There is a belt equipment for this. You must decide which model of a trimmer for the grass to prefer, taking into account this device.

Removing and disassembling the starter, replacing broken parts

To repair the starter trimmer for the grass, first it needs to be disassembled, and then collect it. This process is not particularly complicated. You will need to work the shape of the screwdriver.

Everything should be done carefully, observing precautions, especially so that the spring does not injure the owner in case of accidental departure

Starting analysis

Disassemble the starter mechanism to install new parts instead of broken in the following sequence:

Unscrew the screw that attaches the pulley with the starter lid using a screwdriver; Remove the spring and antennae; Carefully remove the pulley (you need to turn your head or work, after putting on your glasses and gloves); Determine why the trigger worked; If the spring fell apart almost completely, it is replaced; Когда пружина выходит из крючка, она устанавливается на прежнее место, предварительно сгибая антенну (фотографии показывают процесс установки);

After the spring plate is installed inside the groove, carefully tighten it

Read it yourself

To change the spring, the work must be performed carefully and accurately: it can accidentally explode under the influence of the force caused by its bringing into effect. Even if you carefully remove the video, the spring tape is very quickly torn off the coil and can injure the hand with sharp edges.

Immediately put in place a spring plate does not always work. This often slips, so attempts should be repeated to achieve the desired result.

Starter assembly

The assembly of the starting installation is carried out in several stages:

The coil turns over, installing it so that the bend of the spring accurately fits into the groove of the case, as in the photo below;

When making the above manipulations, it is necessary to put two goals. If this is not done, the spring will ultimately damage the plastic cup, and when it is removed, jamming will begin. This makes you feel that spring has come. To eliminate this drawback, it is necessary to install this part of a larger length or an additional goal.

When such details are not enough, you can just unscrew the screw a little, and the starter assembly will start working without fixing. But this option is temporary. It is better to repair it as soon as possible.

Spring tension

After installing the spring, tighten it. To do this, follow the following actions:

  • Remove the handle from the starter cord;
  • Then the rope is inserted into the groove of the coil;
  • The spring is delayed by the rotation of the turn in the opposite direction clockwise (winding);
  • Make the required number of revolutions specified in the operating instructions for the used trimmer model for grass, and the corresponding length of the cord used;
  • At the very end, the rope is lowered into the hole provided for this, located in the starter cover;
  • Place the handle in place by fixing it with a node.

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

  • Insert the corresponding piece of the plate into the groove at the location of the spring hook;
  • Drill holes on both sides of the groove in the coil, into which you need to insert a spring hook and fix it with wire.

Replacing a torn cord

A torn cable is replaced in the following sequence:

  • The old cord is removed;
  • Choose a rope of a suitable size (thickness and length);
  • Having passed it through a special hole located in the coil, tie a knot;
  • Spring valve producing the required number of revolutions;
  • Fix the pen

It is better to tighten the spring plate with Partner so that the edge of the cord does not twist inside the starter mechanism.

We will examine the surface of the oil seal. traces of moisture, or wet pollution, scuffs and other damage on it are a signal to its replacement.

With a thin flat screwdriver (awl, or any similar object that is at hand) we remove the old oil seal (p.50), pry it with a screwdriver from the side of the crankshaft and remove it.

We apply a small amount of oil on the inner surface of the new omentum before installation (you can use oil, which is used to prepare a gas station).

Replacing the seals of the Chinese trimmer for grass.

One of the main causes of air leaks into the engine are crankshaft oil seals. In general, this problem is the most common on Chinese trimmers, and in some cases, seals begin to pass the air in the first year of service. All the fault of low.quality rubber products of such mowers, well, no one has canceled natural wear.

Essle for different sizes were installed on both sides of the crankshaft (12227mm small and 15307mm large). You can safely sin on the seals if it begins to “snot”. Another indicator of their malfunction is floating turnover when working for “hot”. Next, we will consider in detail the process of replacing.


Trimmer for grass gasoline Patriot RT 3355 is designed to trim and mow low grass on lawns, streets, around trees, along the roadsides, on lawns and garden areas. The unit is successfully used on even and relief, uneven areas. The manufacturer improved the model taking into account convenient transportation and easy use: the bar is made by a detachable, quickly assembled and disassembled. The comfort of operation adds a wide shoulder belt with an adjustable length. Fast launch is simplified by the primer.

Stages of starting a trimmer for grass of gasoline Patriot RT 3355

  • The freshly prepared mixture is poured into the tank.
  • It is transferred up to the “cold” position, the air damper lever.
  • The ignition on the control handle is set to the “inclusive” position.
  • 5-7 clicks on the primer button to fill the carburetor with a mixture.
  • A trimmer for grass is laid on a stable surface at a safe distance from objects and people. The contact of the trimmer head or cutting knife with the ground is avoided.
  • The gas trigger is pressed on the control handle and is fixed in this position.
  • With one hand holds a trimmer for the grass, and with the other hand stretches the starter handle until the “hook”. At this moment, the handle pulls sharply until the engine is launched.

The engine is launched with preliminary stretching of the cord. Make sharp jerks of an unreliable cord or pull the cord until the stop is not worth it due to the high probability of a starter breakdown.

  • Install the lever of the air damper in the middle position.

Three.dimensional starter. device and principle of action

In order to independently fix the gasoline starter, you need to understand the principle of its operation and know its device. To date, trimmers for grass have manual and automatic starters, and the first. the most common

Part is a plastic case in which a pulley with a cord wound on it is placed to start the engine. In order for the cord to be wound independently after winding the tool, the steel belt is located inside the pulley. A rattle is installed on the front of the pulley, which blocks the starter on the drive shaft of the tool motor.

The note! Depending on the model and brand from which a trimmer for grass is made (Huter, Husqvarna and other brands), the ratchet can consist of one or two separate components.

The principle of the manual starter is the same for Chinese, European and domestic production of a gas trimmer for grass, whether it be Hitachi, Patriot or another manufacturer. To start the engine, the owner of the device abruptly pulls by the cord. The pulley rotates from this movement, and the protrusions located on it enter into the hook with dogs located on the flywheel. Then the flywheel and crankshaft begin to rotate the pulley. After starting the engine under the influence of the centrifugal force, the crests and dogs diverge in different directions. And after the user releases it, the starter cord is wound on the pulley using a return spring.
