How to assemble a starter on a trimmer correctly

At some point, the tasks with the starter appear on any trimmer-STIHL FS 55, MTD 790 or another brand. You can delay the occurrence of such a malfunction, but for this it is necessary to carefully handle the inventory. Namely. You should not make very sharp jerks, this will lead to a break in the cord or to the output of the spring. It is not recommended to expose a benzoocos by attacks or other physical influences. If the starter case breaks, and the cord breaks off, it can be wound on the flywheel of the motor. This will lead to a broken pulley and a bursting spring.

So, finding that the starter mechanism has broken on the gas station, you should not rush to the specialists to immediately rush for help. Knowing how the malfunction is eliminated and/or the details are replaced, repair work can be performed without the help of others. This does not require any specific tool. At first, the procedure may seem complex and painful, but countless webs dedicated to the repair of the starter will help to solve the case very rapidly and simply.

The device and principle of operation of the starter on the trimmer

The gasoline engine is, in principle, the main part of the motorcycles its power lies in the range of 0.5-2.5 liters.With. The movement from it is transmitted by the shaft located inside the hollow bar, and then through the gearbox, consisting of gears, already a trimmer line or a knife (working body).

Also, benzokos has the following elements:

  • Protective casing;
  • Lever;
  • A belt designed for ease of use of the device;
  • Starter serving for launching a gasoline internal combustion engine.

All parts of the motorcycles are presented in the photo further.

The starter on the trimmer is an integral part, which performs the engine starting into operation. It is shown separately in two photos below.

The starter mechanisms of various models of benzos work according to the same principle: during the launch of the ICE, the protrusions marked in the photograph above the number 1 are included in the hook with dogs 3. When the engine begins to work, they return to their previous position due to the effects of centrifugal. Similar role is also played by wires 2.

The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring screwed around the axis. It unfolds when the rope is pulled. After releasing the cord, it is drawn and winding due to folding the spring. During the launch of the internal combustion engine, the gas.Skating mechanism turns its shaft until it starts to work (starts).

To date, gasoline motorcycles are equipped with two types of starter mechanisms:

The first option is much more common.

The starter on the trimmer can function without breakdowns for a long time. It is impossible to unambiguously indicate the deadline. Everything is determined by the initial quality of the device and compliance with the rules of handling it.

Removing and disassembling the starter, replacing broken parts

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

Parsing the starting node

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

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

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

Starter assembly

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

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

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

Spring tension

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

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

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

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

Replacing a torn cord

A torn rope is replaced in the following sequence:

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

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

Prevention of problems

Sooner or later, problems with the starter arise on any trimmer. STIHL FS 55, MTD 790 or other brand. You can delay the appearance of such a malfunction, but for this you need to carefully handle the tool. In particular, you should not make too sharp jerks, this will lead to a break in the cord or to the departure of the spring. It is not recommended to expose a benzoocos by attacks or other physical influences. If the starter case breaks, and the cord breaks off, it can be wound on the engine flywheel. This will lead to a broken pulley and a bursting spring.

So, having discovered that the starter mechanism has broken on a gas station, you should not immediately rush for help to specialists. Knowing how the malfunction is eliminated and/or the details are replaced, repair work can be performed independently. This does not require any specific tool. At first, the procedure may seem complex and tiring, but numerous videos on the Internet devoted to the repair of the starter will help to solve the problem as quickly and simply as possible.

How to fix a starter on a chainsaw

The reason for the malfunction of the launch system of the chainsaw may be:

  • Drive pulley. This part is subjected to high axial and radial loads, therefore, before starting work, it is recommended to inspect the pulley for damage and cracks on the back of the case. If necessary, repair the part or replace it with a new.
  • Spring mechanism. If he has lost his properties or there are cracks or breakthroughs on it, it is necessary to replace this element. It is also recommended to inspect the places for the presence of defects.
  • The rope of the launch system. The rope should be examined for wear and injuries. If necessary, replace the part and install it with the pulley.

Diagnostics

Diagnosis of the tool launch system is carried out as follows:

  • Unscrew the fasteners and remove the lid.
  • Turn a screw that attaches the mechanism to the protective cover.
  • The starter smoothly launch, removing the spring and clamps from it.
  • For examination for wear and defects, a reel with a cable is dismantled.
  • Check the fuel system for water in it. If there is water inside the system, then the fuel fluid must be replaced.
  • Conduct an inspection of the power unit for overflow with fuel fluid. In this case, you need to unscrew and dry the spark plug, pull the starter, dismantling the air damper.
  • Check the spark of spark.

Replacement of the cord

In order to replace the cord, the following tools will be required:

Replacing the launch cord is as follows:

  • You need to unscrew the fasteners that hold the side cover with a screwdriver.
  • Then dismantle the starter from the tool body.
  • After that, you need to turn the lid and conduct an inspection.
  • Then dismantle the clip and spring.
  • Untie the knot on the rope.
  • You need to pull out the pulley on which the cord is wound. Remove the cord and replace it with a new.
  • Then get the pulley in place and tie the rope on the knot. Set the clip and spring.
  • After that, tighten the lid using fasteners.
  • At the end, install the starter in place and fasten the fasteners.

Spring repair

The procedure for repairing the start of the launch system:

  • Dismantle the starter from the tool.
  • Remove the protective cover.
  • Wind the cord from the end of the pulley to avoid scrolling the mechanism.
  • Pass the second end of the cord in the hole of the protective cover.
  • Pull the cord 17-20 cm to check the turn of the pulley of the spring mechanism.
  • Check the operation of the spring after stretching and releasing the mechanism.
  • Unscrew the circle circle from the side of the generator, removing 3 fasteners.
  • Demolish the pulley and cord.
  • Check the condition of the parts for wear and the presence of damage and cliffs. If the cliff is small, then you can eliminate the defect by welding.

How to put a spring

In order to install a new spring, the following actions must be performed:

  • Gently extract the clip of mechanism.
  • Conduct an inspection of the inner part of the clip in which the spring mechanism is located near the C-shaped element.
  • Fix and pull the upper part of the spring with your finger and pull the launch mechanism to the side.
  • Extract a worn.Out mechanism and wind a new spring. Excesses and twisting of the element should be avoided.
  • Collect a new spring mechanism. It is recommended to do this slowly so that the mechanism does not unwind.
  • Twine the spring and insert it into the starter mechanism.
  • Gently fix the clip.

How to assemble a starter?

The most important thing in the process of independent repair of the starter is to collect it correctly.

After the spring is completely wound, you need to carefully turn the coil and insert into the starter case so that the second spring hook enters the groove of the case.

By installing the pulley (in this photo. Black), look through the hole in it so that the spring hook gets into the groove on the starter cover

Then, if there is a spring under the screw, we install it first, not forgetting to put the washers from below and from above the spring.

Gently insert a cup with antennae into the grooves of the coil and tighten the screw.

Then keep sure that the puck is on the sprout does not fall. Why is it important? The fact is that the spring scratches a plastic cup with its end, as a result of which the latter wear out and begins to tightly pressed with a screw to the reel. For this reason, a situation may arise, very similar to the breakdown of the spring: the handle stretches out of the starter, but does not return back.

However, when the starter is weakened, this problem disappears. It is easy to eliminate such a starter malfunction: it is enough to choose a spring of the same diameter, but a little longer, or put an additional washer. If we simply slightly tighten the screw, then it will be twisted and fly out, and this will increase the likelihood of a spring breakdown, since the pulley will not fit tightly with the starter case.

The coil to the body was screwed, now we need to pull the spring. Before this, it is necessary to remove the starter’s handle from the rope in advance. If the knot is too durable, then you can just cut it or try to untie it, for example, using a pair of pliers.

This is done so that after you bring the spring, you can pass the rope into the opening of the starter cover. The second end of the rope should be fixed in the coil even before it is installed in the case, it is not required to be roped on the pulley before pulling the spring. You will do it after.

Before taking a spring, estimate how much the reel revolutions should be wrapped in a rope. Suppose the length of the rope at the starter of the Motor ADA Grounddrill-5 corresponds to 5.5 revolutions around the coil. In this case, we make at least 6 revolutions of the coil in the direction opposite to the direction of wiring.

So, let’s get down. Without wrapping, insert the rope into a groove specially designed for it in a coil. Everything is ready, proceed to pulling the spring. To do this, we rotate the coil counterclockwise. In the direction opposite the direction of rotation of the coil when watching the rope.

It is more convenient to do this not on the knee, but pressing the starter with one hand to the floor, and the second turning the coil right behind the rope mounted in it. If the experience is not enough, then you can rotate with both hands directly the pulley itself, but the rope will interfere with it, which can create additional inconvenience.

By the way, on your own, you can introduce some refinement to the design of the starter in order to more reliably fix the end of the spring inside the coil. There is enough fantasy here. Now I will explain what it happens for. It often happens that the spring in starters of this type after the first such independent repair and installation of the starter on the unit flies after a few jerks again. There is no hook in the groove of the coil.

And this despite the fact that the coil is almost tightly adjacent to the starter cover and the spring there, well, should not even hang up and down freely, and even more so until the spring out of the gear. It turns out that when the cable is jerking, it pulls the spring, pulls out of the groove.

How To Quickly Fix Your Recoil Pull Starter On Your Chainsaw, Blower Or WeedEater

In this case, you can make the following: cut a narrow strip of metal, which in thickness could squeeze closely into the groove of the coil with the hook itself. So the hook will not hang free in the groove, which means that it will not be so easy to break out.

A metal plate, tightly inserted into the gap between the hook of the spring and the walls of the groove, will reliably hold the spring

Another solution to the problem: drill small holes in the coil on both sides of the groove and, inserting the spring hook, fix it with a thin wire covered through these holes. But here you need to manage to make sure that this wire does not touch when rotating the starter cover from the inside and does not slow down the pulley.

The design of the starter of your benzo tool is different from the above? Faced with another malfunction or you know the best way to repair the starter with your own hands? Ask questions, share your experience with others. Joint efforts, we can solve the problem of frequent breakdowns of the starter once and for all!

How to fix a hand starter

Recently, many consumers have begun to give preference to power plants with an electric starter. Such a device is much easier to use, it is more convenient to start and operate even an inexperienced user. But do not forget that if the battery is broken or refuses to work, then it will simply not work to start the equipment using an electric steamer. For this reason, manual start is considered more reliable, especially if you work with the installation far from the city, it is better to take this element with you to continue to work.

Generatoron one’s own every user should know

Starter is one of the most important details of any device, because without it it will not work. But, unfortunately, it often breaks and leads to problems with the start of the engine. Therefore, if possible, stock up on an additional manual ignition, which can be installed instead of a faulty part.

Replacing a drawing starter

The main problem of the retracting relay (BP) is the burning of contacts (pyatakov). Contacts are burned due to a large starting current during the launch of the ICE, often the contacts are oxidized under the influence of the environment. On many models of VAZ cars, a retracting relay can be changed without removing the starter itself.

Consider the replacement of the launching starter relay without removing the entire starting mechanism on the example of VAZ 2112. Repair is more convenient to produce on a pit or automobile lift, but you can do without them by putting a car on a flat dry site.

  • Open the hood and disconnect the mass terminal;
  • We pull off the red wire with the chip that goes to BP;
  • We dismantle the nut of 13 with the mount of the supply wire, and take the wire to the side;
  • We turn off the lower nut to 13, remove the stator winding wire from the terminal;
  • We take a flat screwdriver (or the key, if the bolts are installed) and the back of the retracting relay is unscrewed by the two screws (bolts) of its fastening;
  • Remove the old BP and install another in place, carry out the assembly in the reverse order.

On the models of the VAZ 2108-09-099, it is not difficult to replace the starter, for this, a hole or auto lift will not even necessarily need. The replacement is carried out as follows:

  • Open the hood and first of all remove the battery terminal (mass);
  • From the retracting relay, disconnect the upper wire with the chip, it simply is pulled off;
  • We turn off the fastening of the plus terminal with BP (key13), take the wire to the side;
  • The same key of 13, we turn off the three nuts of the starter itself, the most difficult thing is to get to the lower nut, but if you try very much, you can get to it;
  • Having freed the knot from all mounts, dismantle it, and put a new starter in place, we collect everything in the reverse order.

Everything, the replacement of the starter of the VAZ 2109 is completed, with a certain dexterity, the work takes no more than two hours.

The engine of the benzokos does not start.

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.

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.

DIY trimmer starter repair: disassembly and assembly, cord replacement, spring winding

Repair of the starter of a gasoline trimmer may be required at the most inopportune moment. In this case, you can solve the problem in two ways: replace the broken part or change the entire node. The latter option will cost more. To repair the device with your own hands in most cases, you need only a screwdriver with an appropriate tip from the tools. Repair work will not take much time and do not require special knowledge. It is enough to know the device, the principle of operation, the nuances of the assembly-disassembly of the starter on the trimmer in order to achieve the desired positive result.

The device and principle of operation of the starter on the trimmer

Gas engine.This, in principle, the main part of the motorcycles its power lies in the range of 0.5-2.5 liters.With. The movement from it is transmitted by the shaft located inside the hollow bar, and then through the gearbox, consisting of gears, already a trimmer line or a knife (working body).

Also, benzokos has the following elements:

  • Protective casing;
  • Lever;
  • A belt designed for ease of use of the device;
  • Starter serving for launching a gasoline internal combustion engine.

All parts of the motorcycles are presented in the photo further.

Starter mechanisms of various models of benzosos work according to the same principle: During the launch of the internal combustion engine, the protrusions marked in the photo above the number 1 are included in the hook with dogs 3. When the engine begins to work, they return to their previous position due to the effects of centrifugal. Similar role is also played by wires 2.

The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring screwed around the axis. It unfolds when the rope is pulled. After releasing the cord, it is drawn and winding due to folding the spring. During the launch of the internal combustion engine, the gas.Skating mechanism turns its shaft until it starts to work (starts).

To date, gasoline motorcycles are equipped Two types of starter mechanisms:

The starter on the trimmer can function without breakdowns for a long time. It is impossible to unambiguously indicate the deadline. Everything is determined by the initial quality of the device and compliance with the rules of handling it.

The main malfunctions of the starter of the trimmer

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

These details are shown in the photo below.

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

Removing and disassembling the starter, replacing broken parts

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

The repair of a gasoline trimmer may be required at the most inopportune moment. In this case, the problem can be solved in two ways: replace the broken part or change the entire assembly. The last option will cost more. DIY device Most cases Of the tools, only a screwdriver with a suitable tip is useful. Repair work does not take much time and do not require special knowledge. It is enough to know the device, the mechanism of work, aspects of assembly and disassembly of the starter trimmer, To achieve good good result.

Dismantling, disassembling the starter of the trimmer, replacing parts

First of all, the repair process begins with the removal of the entire starter from the trimmer. 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 launch, gas troops must be observed, 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:

    We unscrew the screws of fixing the pulley to the starter body;

Installation of a trimmer coil 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 manual for the gasoline trimmer. 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

At the very beginning, it is necessary to extract a ragged cord, select a suitable length depending on the trimmer model. 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. Next, we build a strip spring to the required number of revolutions and mount the handle.

What other types of starters are suitable for a walk.Behind tractor?

Each owner of motoblocks must understand that at first absolutely all starters function perfectly and can delight their owners with this state of affairs for about a year. But without periodic lubrication of details, their verification and the commensurate power of a jerk, such joy will not last long. Take care of the starter and he will answer you with high performance and a long service life.

Starter builder

Assembly Starter assembly It is carried out in several stages:

  • The coil turns over, installing it so that the bend of the spring exactly enters the groove of the case, as in the photo below;
  • Make two goals between which the spring is located;
  • Put a cup with antennas at the destination;
  • Tighten the screw (photo on).

The implementation of the above manipulations is required Put two goals. Failure to fulfill this requirement can lead to damage to a plastic glass over time, and when it is removed, it will begin to jam. For this reason, there is a feeling that spring has come. To fix this defect, it is necessary to install this piece of larger length or additional washer.

When such details are absent, there are several options unscrew the screw, And the starter assembly will begin to work without fixation. Unfortunately, this option is temporary. It is better to repair it ideally faster.

Starters for benzokos: device and installation features

A manual starter for a benzo.Coat or a gasoline trimmer is a mechanical node, which includes a pulley placed on a ratchet. On the pulley in the starting position of the rope wound. At starting, it stretches out. The pulley is spring.Loaded. You should release the end of the rope, how it drowns back. As a spring, a flat ribbon shaped in the ring is used. It resembles a spring in large mechanical watches that start once a day. The starter itself is located more often on the rear than closer to the front end of the mowing or trimmer. In order to correctly produce all manipulations with a starter for benzocosa, you need to know the features of the device and installation.

How is the starter of the benzocouses or trimmer arranges?

Starter- a mechanism as a whole and universal for benzos, trimmers, gasoline and diesel-generating units. It is not a problem to equip even a car, motorcycle or scooter if your vehicle is free to install it. It is not for nothing that many Soviet cars and trucks were equipped with a starting tool, remotely reminiscent of a bent mount bent twice.

The starter assembly has the following details:

  • Spring spring with hook;
  • Cord wound on a coil;
  • Return spring;
  • Temporary drive and the main spring;
  • The body of the mechanism protecting the ratchet;
  • Stop bolt.

The worst variant of the breakdown

There are times when the starter still retained performance, but can break, for example, a worn cord. The ratchet had not yet managed to work when starting the engine, and the rest of the cord is immediately wound on the coil, the return spring is deprived of hooks, grooves break in the starter case. The result. Replacement of both springs and housings.

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 benzocouses.
  • 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.

Also, benzokos has the following elements:

  • Protective casing;
  • Lever;
  • A belt designed for ease of use of the device;
  • Starter serving for launching a gasoline internal combustion engine.

All parts of the motorcycles are presented in the photo further.

The starter on the trimmer is an integral part, which performs the engine starting into operation. It is shown separately in two photos below.

The starter mechanisms of various models of benzos work according to the same principle: during the launch of the ICE, the protrusions marked in the photograph above the number 1 are included in the hook with dogs 3. When the engine begins to work, they return to their previous position due to the effects of centrifugal. Similar role is also played by wires 2.

The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring screwed around the axis. It unfolds when the rope is pulled.
