Starters for lawn mower: device and installation features

A manual starter for a lawn mower or a gasoline trimmer for grass 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 for grass. To correctly produce all manipulations with a starter for a lawn mower, you need to know the features of the device and installation.

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 modern “handbrake” starts from the cord. it is tied to the mechanism, and it is impossible to lose.

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.

If the model of a lawn mower or a trimmer for grass has long been discontinued, it will be difficult to find exactly the same spare parts, and the starter changes entirely.

The main malfunctions of the starter of the trimmer for grass

Find the reason for the breakdown of the starting device is easy. There are several main options:

The designated details are shown in the photo below.

It may happen that the starting mechanism will be broken by the case. 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. How to repair the starter on how to screw a fishing line for a trimmer to a trimmer coil for grass as a trimmer. But such cases when a complete substitution of the starting node is required, very occasionally occur. In most cases, to fix the mechanism, it is enough to put a new spring or replace the cord.

Installation or replacement of the springs of the starter of the mowing, motorcycle, trimmer for grass

But what if we have everything with a rope, and the starter coil (pulley) does not roll? Let’s look at this issue step by step on the example of the ADA Grounddrill gasoline drilling starter, which has a pulley with 2 metal antennas per 2 hooks.

In the case of other types of manual starters of the same design that are widely used in gasoline trimmers, trimmers and motor droplets, the entire starter repair process will look the same, differing only in certain aspects.

Starter repair: disassembly

Unscrew the screw that attaches the pulley to the starter cover. Remove the antenna, spring. How to insert a trimmer starter for grass for grass. FS 38. How to install a throttle handle

The pulley itself is carefully removed so that the spring does not jump into the face. Even with the most accurate disassembly, it usually immediately flies out of the coil and sharply turns into a long iron strip or twists into the rings

Carefully remove the snow.white starter coil. Do not damage the spring! If the spring bursts or one of its hooks and hooks breaks down, the starter repair will not be easily and quickly

It is necessary to replace the spring. In order not to spend money on the purchase of a new starter, it can only be found on sale

If the spring bursts or one of its hooks and hooks breaks down, the starter repair will not be easily and quickly. It is necessary to replace the spring. In order not to spend money on the purchase of a new starter, it can only be found on sale.

Read it yourself

If the starter’s spring is just broken, t. E. One of the hooks is not hooked, just glue it, if necessary, tighten the hooks a little denser (just do not break!) Install the spring with an outward hook in the pulley groove and start twist it, immediately holding your fingers inside the coil and preventing it from jumping out.

Clutching the spring to the pulley, we radially tighten the spring inside

For the first time, the handle of the starter of spring may not seem so simple, but all this comes with experience. Having trained a little, you can easily wrap the spring on the pulley for no more than one minute.

How to install a starter on a trimmer for grass

One of the key parts of the Kustorez is a starter designed to facilitate the start of the device engine. Like other parts, it breaks periodically. In this case, there are two solutions to the problem: to repair a trimmer for the starter’s grass or replace it completely. The second option is simpler, but more expensive. In addition, on sale you must first find the necessary part, since different models of lawn mowers use different starters. If you have free time and a screwdriver with an appropriate tip, you can restore the performance of this device, if you know how it works, what defects are characteristic of it and how to fix it. All this is in this material.

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 manufacturers of gas trimmers, 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.

Important! With intensive use of the drive cord, it breaks over time, and the spring wears out. These details are easy to replace with your own hands

Signs and reasons for the failure of the starter

In rare cases, the executive mechanism breaks when the tool is inaccurate. The consequences can be unpleasant: the deformed cord is wound on the flywheel of a working engine, a pulmonary pulley and a spring break. But these are isolated cases, a complete replacement of the starter is rarely required.

Diagnostics and elimination of malfunctions

To diagnose the starter mechanism for the purpose of its further repair, it is necessary to disassemble the assembly. It’s not difficult to do, just a screwdriver is needed. But during this operation you need to be careful. With careless movements, the spring can fly and harm the user.

How to change the starter cord?

It happens that in the impossibility of starting a starter is not a spring to blame, but the cord itself. He can seize or completely break. Dismantling the starter of the lawn mower or trimmer for grass is universal in its steps.

• Remove the starter block from a trimmer for grass or lawn mower.
• Unscrew the main bolt holding the handbrake.
• Pull the coil and melt the remains of a worn cord from it.
• Unscrew the knot on the handle of the cord and pull its end from it.
• Untie the knot at the other end (at the beginning of the coil) and remove the old cord. The nodes that have become tight are unleashed with pliers or ticks.
• Tie a knot on one of the ends of the new cord, prone it through the hole at the beginning of the coil (closer to its axis).
• Shin a few turns of a new cord to the coil. If it is long, then cut the excess.
• Season and soak the spring tensioner (if it starred) and spring.loaded elements in the correct sequence.
• Put the coil in place and take the free end of the cord to the outlet of the starter and in the handle.
• Install the starter block in place.

Twist the starter by the cord, start the engine of the lawn mower or a trimmer for grass. The larger and more powerful the engine, the more cord jerks will be required when starting, the norm is no more than 7 times. The result is a quick and smooth launch of the motor, the readiness of the unit for work.

Repair of the starter of the gas trimmer for grass may be needed at the most inopportune time. At the same time, there are two ways to solve the problem: replace a broken part or replace the entire assembly. The last option will cost more. In most cases, only a screwdriver with a tip is required to repair the device with your own hands. Repair does not take much time and does not require special knowledge. To achieve the desired positive result, it is enough to know the device, the principle of operation, the nuances of the assembly-disassembly of the starter for the trimmer for the grass.

The device and principle of the starter on the trimmer

Gas engine. This is mainly the main part of the brush. Its power lies in the range of 0.5-2.5 liters.With. Movement from it is transmitted to the shaft located inside the hollow rod, and then through the gearbox, consisting of gears, already stabbed or knife (working body).

Bigorezes also have the following elements:

• Corrugated board;
• lever arm;
• belt designed for simplicity of use;
• Starter used to launch an internal combustion gasoline engine.

The starter of the trimmer for grass is an integral part of the engine start. This is shown separately in two photos below.

Starting mechanisms for different models of gasoline braids work according to the same principle: when starting an internal combustion engine, the tongues indicated by the number 1 in the photo above are hooked by dogs 3. When the engine is launched, they return to the previous position due to centrifugal force. A similar role is played by wires 2.

The process of returning to the initial position of the elements of the mechanism is due to the presence of a spring wound around the axis. It turns around when the rope is pulled. After the release of the cord, it is pulled and wound with a spring assembly. When the internal combustion engine is launched, the trigger rotates its shaft until it starts to work.

Today, gasoline scooters are equipped with two types of starter mechanisms:

The first option is much more common.

The trimmer starter for grass can work without breakdowns for a long time. It is impossible to clearly indicate a continuous period of time. Everything is determined by the initial quality of the device and compliance with the rules of its operation.

The main malfunctions of the trimmer for the grass of the starter

It is easy to determine the reason for the refusal of the starting device. There are several main options:

Perhaps the starter mechanism is accidentally broken. The consequences will be deplorable if the wrapped cable is wrapped around the flywheel of the internal combustion engine: then the spring will burst and the pulley will break. But such cases when a complete replacement of the starter is required are extremely rare. In most cases, it is enough to fix a new spring or replace the cord to fix the mechanism.

How to pull the spring

Spring repair

If the material of the starter spring is poor.quality, the spring bursts (usually at the place of its connection to the drum, where it forms a loop). Replace the spring in this case is not worth. Carefully clean its surface from dirt and traces of lubrication, gently polish the destruction place, and then release the spring at 600 650 ° C (the spring steel should purchase raspberry color). It is necessary to cool the spring slowly, and at 100 150ºС you can already carefully wrap its end in the shape of a restrictive protrusion on the inner surface of the drum (steel will acquire the necessary plasticity) and insert into place. Simple repair of the starter of the chainsaw of Repair Starter Chainsaw how to pull the chain on. The elastic properties of the spring will not change.

Tightening the spring PIM

The spring is pulled with a canvas worn on the drum. The tension and configuration of PIMs are made according to the following algorithm:

• Traction springs are put on the canvas (they are included);
• The spring mechanism is pulled (the number of revolutions depends on the diameter of the shaft and the mass.body characteristics of the canvas. you can find out the approximate number of revolutions from a special table);
• The spring is fixed with special brackets;
• traction springs are refueled in a shaft in special slots located at its ends;
• The lock of the spring is removed;
• The smoothness and speed of the canvas is checked (it is necessary to hold it with your hand to exclude sharp blows of the stoppers on the lower lamella on the edge of the box and, if the stoppers have not yet been installed, avoid complete winding of the canvas on the shaft).

Practical recommendations

In order to compare holes for fixing the cord in the pulley and the case, you may have to make a few more turns. A new rope is threaded into a technological hole and make a loop or knot: this will allow it to slip out of the pulley. The rope is taken to the side so that it does not interfere with further work. Next, it is necessary to fix the pulley.

First you need to install a smooth launch spring in place. It can be used the same if damage is not detected in it. or new replacement if necessary. A starter clamp is installed on top of the spring, which is fixed with a special screw. In the article we will tell you how to adjust how to adjust the carburetor on a video chainsaw. He reliably fixes the clamp for a long time, avoiding its distort and swing. I have a carburetor mounting stilettos on a chainsaw, how to change it? After that, you need to make a few turns of the rope and start it inside. The cover with the assembled starter is installed in place. With the help of screws, it is fixed.

After the repair and assembly is completed, you can start work. Self.repair of the starter does not take much time and does not require complex skills, but saves time and money if you perform such work in the service center.

It is necessary to approach the repair of the chainsaws responsibly and timely to carry out preventive examinations, monitor the quality of the fuel and oil used. These simple manipulations will increase the duration of the tool in working condition.

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 is the starter of the lawn mower or a trimmer for grass?

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 modern “handbrake” starts from the cord. it is tied to the mechanism, and it is impossible to lose.

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.

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.

Repair of the starter of a gasoline trimmer for grass 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.

Diagnostics and elimination of breakdowns

To diagnose the starter mechanism, with the aim of the subsequent repair of it, the node must be disassembled. It is easy to do this, only a screwdriver is required. But during this operation, you need to be neat. with careless movements, the spring can fly out and injure the user.

Removal and analysis of the node

The procedure for disassembling the starter is to perform a certain sequence of actions:

First you need to find a screw connecting the starter cover with the pulley, and unscrew it; Then you need to remove the spring, antennae and washers; Then you should carefully remove the pulley, holding the structure away from the face, so that the bounced spring does not injure the user; Next, it is required to inspect the spring: if it is damaged, then you need to put a new one (the cost of such parts is low), and if it jumped out of the hook, it is necessary to return it to its original place, having previously made bends if they have broken off.

Sprinking spring

Spring winding is not an easy procedure. Not everyone gets to install the part on the place the first time, so you should not be upset if it is failure. It is necessary to repeat attempts until the actions are not crowned with success. If you wish, you can watch a video on the Internet, where people’s craftsmen tell in detail and show how to easily and quickly perform this operation.

Important! When winding and installing the spring, you need to remember that it is suppressed, which means that it can burst if you make too much effort. A new part is inexpensive, but you will have to spend time on its search, which means that work on the beard of herbs will move back for an indefinite period

To wind the spring, you need to place the bend in the groove, and then, turning the coil, carefully lay the part along the inner diameter of the bobbin. In this case, the spring must be constantly held with your hands. if it is not fixed, the part slips and pops out, then the winding has to be re.performed. When everything is done correctly, the spring holds tightly in its seat.

Replacement of the cord

A torn trimmer cord for grass must be changed to a rope, you can linen, but without fail suitable in thickness and length. Buying a lanier for the starter of the lawn mower in this case is optional to buy in a specialized store.

To replace the element, in the coil you need to find a hole for it, through which to skip the cord, and then tie the knot. Then you need to take a reel with a spring, having performed several revolutions.

On a note! The exact number of turns can be found by watching the instructions for using a trimmer for grass, or manually. To do this, you need to measure the length of the rope and calculate how many times it can be wrapped around the coil.

For example, if the cord turns around the circle six times, then to pull the spring, you need to turn the coil by the clock six times. After that, it remains only to go through the rope through the hole and fix the handle on the cord.

Other malfunctions

Sometimes after the repair, the spring still flies. You can eliminate such a malfunction with two solutions:

• So that the bend of the spring does not pop out of the groove, you need to insert a small fragment of the metal plate between the bend and the wall of the seat. This will provide a denser fixation of the spring.
• Home.made fastening also helps to keep the spring in the groove. It is necessary to drill holes in the reel on each side of the groove, place the spring bend in them and fix it with a piece of wire. These actions should be performed so that the wire does not touch the starter cover and does not slow down the movement of the pulley.

Collection and installation to the starter place

To assemble a starter and install it on its original place, you need:

• Turn the pulley with the spring down and place the housing into the case so that the spring bend falls exactly into the groove of the case;
• install the puck, then the spring, on top of it. the second washer;
• Place a cup of antennae on top of the puck and screw the screw.

When assembly, both goals should be put, otherwise the plastic cup will be damaged by a spring after a while, and when tightening the cord, the user will notice that it was jammed. It will look like a spring has flown. To eliminate such a breakdown, you will need to install a larger screw or another puck. If you find the required details it is not possible, it is enough to loosen a little, after which the starter will stop jamming. However, you need to understand that these are temporary measures, and the malfunction should be fixed as soon as possible.

Trimmer starter. device and principle of operation

In order to independently repair the starter of the gasoline cutter, you need to understand the principle of its work and know its structure. Today, manual and automatic starters are installed on trimmers for grass, the former is the most common.

Part is a plastic case in which a pulley is placed with a cord wound around it for Engine starting. In order for the cord independently twisted after winding the tool, on the inside of the pulley there is a strip spring with alloy steel. A ratchet is installed on the front of the pulley, creating a starter’s engagement with a drive.shaft of the tool engine.

The principle of operation of a hand starter is the same for gasoline incisors of Chinese, European and domestic production, whether it be Hitachi, Patriot or another manufacturer. To start the engine, the owner of the device abruptly pulls the cord. The pulley rotates from this movement, and performances on it are faced with the paws located on the flywheel. Further, the flywheel and crankshaft begin to rotate with the pulley. After the engine is launched under the influence of the centrifugal force, the paws diverge in different directions. And the cord after the user releases it, wound around the pulley using a return spring.

Removal and analysis of the node

The procedure for disassembling the starter is to perform a certain sequence of actions:

First you need to find a screw connecting the starter cover with the pulley and unscrew it, then you need to remove the spring, antennas and washers; Then you should carefully remove the pulley, without removing the structure from the face, so that the spring does not accidentally bounce off the user; Then you need to inspect the spring, if it is damaged, then you need to put a new one (the cost of such parts is low), and if it jumped out of the hook, you need to return it to the original place, making bends if they break off.

Starter for lawn mower: device, assembly, repair

When purchasing a gasoline trimmer for grass, you need to be prepared for the fact that it, like any other similar device, is subject to various kinds of breakdowns and malfunctions. They can be associated with the failure of any detail. To understand the device of the mechanism, carry out the repair of the starter, or make such a starter for the lawn mower with your own hands, you need to know and what it consists of. The main component of a gasoline braid for grass is a two.stroke internal combustion engine, with a capacity of 0.5 to 2.5 liters.With., with a volume of 30-40 cm3. He is the help of a shaft located in a hollow bar drives a cutting tool through a gearbox. The gearbox consists of two conical gears transmitting torque to the working body. Which is used by cutter or cord nozzle. The device of the lawn mower provides for the presence of: a protective casing of an arcuate handle of a shoulder or knob belt for the convenience of controlling and moving the device. It is to launch the internal combustion engine that the starter is used. This is an integral part of the engine, without it it is not possible to put the mechanism into operation. The principle of work of the starter of various models of the lawn mowers is not much different from each other. When starting the engine, the protrusions (1) adhere to the dogs (3), after the engine earned under the influence of centrifugal force, they diverge. The same function is performed by wires (2). The cost of a starter for a lawn mower is not a penny, so before going to a spare parts store or a repair workshop, you yourself should understand the existing problem. Determine the reason for the exit from the construction of the starting of the mechanism is not an archbound task. Of course, no one is safe from the fact that when starting, the rope will break and wrap up on the flywheel of an already operating engine. Then the consequences are deplorable: the pulley is torn, the spring burst. Accordingly, the repair consists in the full replacement of the starter. But this is, as a rule, an isolated case. Basically, the refusal of the starter of the gasoline mowing is to break the rope or exit from the gearing of the spring, its breakdown. When the shhorgalok is cut off, the repair issue is solved very easily, by replacing the rope. The old fragment is removed and a new piece of linen rope is installed in the corresponding size. To do this, it must be put into the coil hole and tied it. Take the spring to the required number of revolutions, after installing the handle, similarly to make the knot at the other end, as shown in the photo from above. Such unpretentious repairs are carried out when the shomorgalka exits the system. When breaking the spring or violation of its hooking it inside the starter, you need to disassemble the device and replace the destroyed spare part or restore the engagement. It should be noted that the cost of the spring is much less than the starter assembly. Therefore, you should not be afraid, and after reading our instructions, you do the repair with your own hands without resorting to excessive costs. Let’s start with the starter disassembly. As an example, we use a starter with a pulley with two metal antennae for 2 hooks. Other starters used to launch gasosocos, trimmers and motorcycle engines are repaired similarly, taking into account minor nuances in the structure.

The disassembly of the starter-assembly is not a serious problem, it will simply require a little skills in handling a screwdriver and most importantly, observing some safety measures:

Spin the pulley mounting screw to the starter cover. Remove the two antennae and the spring, after which it is extremely neat, turning your head in the other direction, dismantle the pulley. The specifics of this operation is such that even with a careful removal of the video, the spring instantly pops up from the coil, turning into a sharp metal strip that can injure the repairman. Analyze the nature of the breakdown. With the complete destruction of the spring, the only correct solution would be to replace it. The part who has left the system can easily be purchased in online stores engaged in the sale of starters and spare parts. If the spring just got out of the hook, you need to insert it into place, having previously bend the Usyk. You need to do this carefully, since it is fried and with a neat handling at any time it can burst. 2. Returning the spring back to the groove, slowly and holding it with your finger, start twisting. At the same time, pay much attention to safety, since a broken metal strip can injure. It is not easy to refuel the spring from the first time, some experience is required, so if an attempt is unsuccessful, it is required to repeat more than once. 3. After the spring is wound, we continue to assemble the starter. Carefully turn the coil and insert it so that the bend of the spring clearly got into a special groove in the case. four. Install the puck under the screw. spring and puck again. Then we insert a cup with antennae and tighten everything with a screw. The starter is assembled. It is necessary to pay attention to a nuance such as installing a puck. It should never be missed. If this happened, then the spring will scratch the plastic cup on which the sample will appear over time and it will begin to tighten the screw and click tightly. As a result, there will be a feeling that the spring has flown and repair is required. This drawback is easy to eliminate by replacing the spring with a longer one or by installing an additional goal. If there is no spring or washer at hand, you can release a little screw and the starter will work without jamming. But this is a temporary measure, with prolonged use, the screw will unwind and be lost, which is fraught with a spring output and output from the starter system in general. The next step will be the stretch of the spring. To do this, remove the handle from the rope starter. Next, without wrapping, insert the rope into a groove specially designed for it in a coil. Tighten the spring directly. To do this, rotate the coil counterclockwise. in the direction opposite the direction of rotation of the coil when watching the rope. The number of revolutions should correspond to the value indicated in the starter model and the length of the rope. After the required number of revolutions is made, we extend the end of the rope through the hole in the starter cover, set the handle and fasten it with a knot. It is better to do this together with an assistant so that the edge of the rope does not hit inside the starter. If, after the repair performed, the spring flew again and the launch of the chainsaw is not possible, then the repair procedure will have to be repeated. But at the same time immediately modernize the starter. To get rid of the sprinkle tickling, you can use two ways. The first is to use an additional metal strip, the second in the drilling of the coil (photo) and fastening the edge of the spring with wire

How to change the starter cord?

It happens that in the impossibility of starting a starter is not a spring to blame, but the cord itself. He can seize or completely break. Dismantling the starter of the lawn mower or trimmer for grass is universal in its steps.

• Remove the starter block from a trimmer for grass or lawn mower.
• Unscrew the main bolt holding the handbrake.
• Pull the coil and melt the remains of a worn cord from it.
• Unscrew the knot on the handle of the cord and pull its end from it.
• Untie the knot at the other end (at the beginning of the coil) and remove the old cord. The nodes that have become tight are unleashed with pliers or ticks.
• Tie a knot on one of the ends of the new cord, prone it through the hole at the beginning of the coil (closer to its axis).
• Shin a few turns of a new cord to the coil. If it is long, then cut the excess.
• Season and soak the spring tensioner (if it starred) and spring.loaded elements in the correct sequence.
• Put the coil in place and take the free end of the cord to the outlet of the starter and in the handle.
• Install the starter block in place.

Twist the starter by the cord, start the engine of the lawn mower or a trimmer for grass. The larger and more powerful the engine, the more cord jerks will be required when starting, the norm is no more than 7 times. The result is a quick and smooth launch of the motor, the readiness of the unit for work.

Starters for lawn mower. device and installation features

Repair of the starter of a gasoline trimmer for grass may be required suddenly. Here you can solve the case with 2 methods: change the broken part or change the entire node. The latter option will cost more. To repair the device on their own, only a screwdriver with a suitable tip will almost always come in handy from the tools. Repair work will not take extra time and do not even require special knowledge. It is enough to know the device, the mechanism of work, aspects of the assembly-disassembly of the starter on the trimmer to achieve a good good result.

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 fishing line or a knife (working body).

Also, the lawn mower 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 the 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 ICE of the lawn mower, the triggering 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.
