The cord of the starter of the chainsaw is not pulled out. The chainsaw saws crookedly

The starter of the chainsaw rotates tightly

Today, a chainsaw is a reliable and indispensable assistant to both professional craftsmen and amateurs in the case when they need to perform a large amount of construction work, tie a tree or cut thick branches on it. The chainsaw, unlike its electric counterpart, is driven by the internal combustion engine, so it does not burden the master with long power cords and does not tie it to the outlet. In a word, chainsaws are autonomy and convenience.

But sometimes it happens that the chainsaw does not want to start in any way. You habitually pull the starter’s cord, and the engine does not react to this. With a high degree of probability, we can say that the culprit of the problem was one of the elements of the device launch system, its starter. It happens that the cable starting the saw moves unevenly, with jerks, and it happens that it does not react at all to your effort (there is no return). Most often, the cause of problems with the start is a breakdown of the starter pulley or its spring.

In any case, to understand the cause of the breakdown, you will have to disassemble the starting mechanism to check. To repair the starter of the chainsaw, we will need a regular set of screwdrivers of various sizes and configurations, which is at the disposal of any master.

The procedure for disassembling a chainsaw for repairing or replacing the starter

• Put the chainsaw on the side and unscrew the screws alternately, which attach the side cover of the case. In addition to the screws, you should also carefully unfasten the special latches on the lid. Most often, the starter is attached on the inside of the chainsaw cover.
• Unscrew the fixing screw in the upper part of the starter with a screwdriver and put it in a separate box.
• Remove the plastic starter clamp and put it aside.
• If your chainsaw is equipped with a spring that provides a smooth launch of the device, also remove it and put it next to the clamp.
• Unscrew the node fixing the starting cable on the pulley, and pull it out of the device.
• Remove the pulley itself from the chainsaw cover.

Now is the time to start searching for the problem

• Carefully look at the pulley. Most often, the cause of the pulley malfunction is mechanical damage (cracks or tears), which do not allow it to respond correctly to the movement of the launch cord.
• Check the integrity of the starter spring. Often the upper edge of the spring breaks, which is addressed to you during disassembly. Often, the emphasis on the lid of the case, to which the spring is attached, often fails.
• If you find the failed details, they should be replaced by serviceable, and then assemble a chainsaw in the reverse order.

Repair procedure

Features of the operation of the starter imply a sharp and gross effect, which sooner or later affects the form of breakdowns. Fortunately, in this mechanism, there is nothing particularly to break and the instructions described further affect all possible causes of malfunctions. Starting with how to restore or how to insert a spring into a chainsaw starter, and ending with the installation of dogs with a flywheel film. Step.by.step guides, sequentially, for each problem.

Restoration of the spring

The most popular case of breakdown is associated with the riding of the mounting ear of the main strip spring that reinss the cable. It is not necessary to search and buy a new spare part, since the procedure requires a minimum of time and tools. Only 2 things will be needed: source of fire (a gas burner or stove) and pliers.

Gently take out the spring from the body. You can put a slotted screwdriver.

At the site of a broken ear, you should make a new one by performing an ordinary bend of the tape. So that the metal does not burst, before the bend it must be heated red.hot and bend it to cool (it is better to do this directly above the fire).

The shape and size of the bended part should be identical to the original in order to tightly fit the restraint to the protrusion. How to tuck a spring into a chainsaw starter and save your nerves, is described below. Before starting installation, wait for complete cooling.

How to install a chainsaw starter spring

The basic dexterity and standard dexterity of the hands, combined with simple technology, will reduce time costs, allowing the operation to quickly and almost naturally. The installation of a return spring begins with a fixing of the ear on the recess, in the direction counterclockwise (if you look at the inside of the spring body).

The tape is invested gradually, layer by layer. The already placed part of the spring adheres to the thumb of the right hand, while the finger of the left laid a new segment. Having put about 1/3 of the circle in the case, the tape is pressed with the thumb of the left hand, the right one is brought to it and the cycle is repeated. The entire installation process takes no more than a minute.

Even easier to insert a new spring purchased as a spare part for the starter. It can be in a fixing winding that is gradually removed when installing. The already twisted element is simply inserted into the case. The easiest option is a ready.made kit with a strip spring in the case, which are put in place of old elements in one motion.

Replacement of the cord

Cases of a cut of the handle cable are quite common and characteristic, both Chinese models and branded manufacturers. Since this connecting element is subjected to serious loads and periodically breaks, the process of cornering is extremely simplified. First of all, it should be determined how long the cord should be on the chainsaw. Depending on the size of the drum and the diameter of the cable, the value is located in the region of 120. 140 cm (necessarily with a small margin). Having prepared a suitable segment, you can take a cross screwdriver and proceed to the replacement.

Remove the starter from the chainsaw and unscrew the central screw on the ratchet.

We take out the drum and remove the old cord.

We spread a new cord through the hole from the inside of the drum groove (for convenience, the ends can be melted with a lighter).

We pull the end from the hole ≈ by 10 cm and tie it into the knot so that the cable does not fly.

Into a special recess under the drum, lay the knot and the remaining part of the cable. In order not to rest against the spring body, it is advisable to leave about 1 cm.

We install the drum in its place, combining the spring with the ear, and press the puck with a puck (do not wound the cord).

We spread the opposite part of the cord through the starter case and the hole in the handle, after which we make a fixing node at the end.

The cord winding is carried out due to the spring. Just slightly pull the cable from the hole in the drum to its edge, and holding it at this point, rotate the drum clockwise. The spring is strained, and when released, the cable itself wraps up. Repeat the procedure until the handle is tightly pressed against the body.

Replacing the ratchet

The main element that transfers rotation to the flywheel is subjected to serious wear in places of contact. The teeth of a plastic ratchet (pulley) resting on dogs (especially iron) have the property of rolling or washing, seriously complicating the launch process. The second problem relates to a ratchet with a lightweight start, connecting to the drum through a spring, which can break off at the mounting site. The strip spring can be restored by following the above instructions, and with a screw chip, the structure will have to be replaced. How to remove and install a ratio of a chainsaw starter is shown further:

How to assemble a starter correctly

The nuances of the design and interaction of the details of the mechanism determine the complexity of its maintenance. Manual starting of a chainsaw consists of a minimum set of components, whose work is built on an extremely simple principle, intuitively understandable during the first, thoughtful analysis. You can explain how to assemble the starter of the chainsaw, you can very briefly, a couple of the following sentences:

The strip spring is invested in its case and is installed with it on the starter. The drum with a fixed cord is placed on the spring, clinging to her ear. The design is pressed with a screw with a puck through a hole in the ratchet.

This runaway excursion reflects the main assembly steps. A more detailed description of each movement, with the nuances of various models, the process of tensioning the cord and replacing dogs, is clearly presented in the above instructions. Choose the topic of interest to you, read, see and implement.

The main reasons why the chainsaw is not started on the video. The video will be useful for those who quickly want to start a saw, the author gives practical advice.

In case of a situation where the chainsaw is not started, it is important to correctly conduct diagnostics, determine the direction in which the malfunction should be sought. Do not use a tool that does not work at idle, as this indicates the presence of air leaks into the engine and can lead to serious problems

If the experience in repairing the chainsaws is not enough, it is better to contact a specialist who will save your time and nerves.

Why flies a candle on a chainsaw?

In most cases, the reason for filling the candle is a breakdown or clogging of a carburetor. To disassemble, inspect and rinse it, the fuel node will need to be removed.

• Twist 3 metal screws and remove the protective plastic cover;
• Gently remove the upper foam of the air filter. In this case, you need to inspect the filter element and make sure that there is no need to flush or replace it;
• Dismantle the fuel hose, trying not to break and not to go too far;
• Derive drive traction;
• Gently disconnect the tube for supplying gasoline and the tip of the standard cable.

After disassembling the carburetor, you will need to inspect its membrane. It should be whole and elastic. If the surface of the membrane managed to grieve, then most likely this was the reason for filling the candle.

Other faulty elements of the carburetor must also be replaced, and rinse the remaining old parts in pure gasoline. After the spare parts complete drying, you need to assemble the fuel node and install it on the chainsaw in the reverse order.

Repair of the starter of the chainsaw Interskol

This saw was bought about a year and a half ago when the construction began.

The other day, going to saw off the board, I could not start the engine.Symptoms, the starter is pulled away, but is not included in the hook with the flywheel.We disassemble.

Having removed the starter case, the visible causes of the breakdown did not find.It is necessary to disassemble further.I twist the central screw.It turns out the mechanism consists of several parts and two springs (usually one spring).That’s just the second additional spring and broke off.

Just in case, I removed the main spring for inspection, it turned out to be normal

On an additional gently, pliers, without sharp excesses, made a hook

Take care of your eyes.Then he installed all parts of the mechanism in its place.Now you need to take the spring.To do this, we lay the starter cord clockwise to the technological cut.

We rotate the coil with the cord clockwise, overcoming the force of the spring.I wrapped six revolutions, each time checking that the entire cord was wound on a reel.

Then we collect the saw and rejoice at the work done and the money at the workshop

I thought, looked, chose, and bought Huski, but not the same “new”, but an order of magnitude older, the so-called American, the neighbor has the same, but one hundred percent, although Swedish, but China, and even with a sound They are different, even somehow I would say it, my own is just Ferrrari.While he burned five liters already in a year (oils), drove the entire tire into acacia, even without a hint of breath. The man himself does not get tired yet, how glad I am not to take this Chinese rubber. There is a braid for the grass, Chinese, I’m not a starter, so a gearbox or carbure, I pick it up if I hadn’t started, I would have already thrown out the fuck and take a hand mowing.

Когда лет 13-14 назад занимался дровами был у меня Oleo-Mac 936, по тем временам диковенной аппарат (по сравнению с Хусками Штилямиии Партнёрами), настоящий итальянец.So he worked his own without complaints.And here what kind of serious demand can be, from the Chinese saw.And the starter spring burst on Oleo-Mac, and several times.

They offered me, but I refused her, because for me he was also “wild”, then he was afraid to run from the spare parts, I did not know what she was eaten with.

Great! I have the same shit only Patriot Garden.It works for three years, prepared a bunch of firewood for heating seasons.And there was the same breakdown. The tip of the return spring broke out.bended in a new one and all the norms. Apparently this is a universal sore.

Replacing the starter cord

Иногда приходится столкнутся с проблемой разрыва шнура ручного стартера. Rupture of the cord as a rule occurs due to its mechanical wear of the related over time or with improper operation of the technique.

The main reason is in the wrong factory, before the factory of the mechanism you should choose an idle move on the starter, slightly tighten it until it stops and only then attach an effort for the factory.

Also, the starter’s cord is often torn due to the irregular assembly angle, pay attention to that when stretching, the cord should not leave the starter from a large angle.

Another frequent cause of the gap, there may be a partial breakdown of the starter, the guide sleeve (ring, insert) wear out or breaks down, which smoothes the cord output angle. Therefore, the state of this element should be monitored.

And finally, the reason may be the usual wear.

Deciding on the cause of the rupture of the cord and eliminating it, we proceed to the replacement.

To replace, we first need to dismantle the starter. For example, consider replacing the starter cord on a lawn mower with a Honda engine GCV160 model. The starter is attached to the engine with three nuts. They should be unscrewed carefully, as the stilettos of the engine holding the casing can begin to unscrew. By unscrewing the nuts, we just remove the starter and inspect the presence of damage, if everything is fine, then after cleaning and removing the remains of the old cord, we proceed to replace.

The starter’s pulley should be scrolling by tightening the return spring almost to the stop. Then weaken a little, combining two holes, the first. the weekend on the starter case and the second on the pulley.

After that, holding the starter’s pulley in place, we stretch the cord starting the output from the outside to the opening in the pulley, we recommend that you first melt the tip of the cord. After the cord is stretched, we tie the knot on the tip, pull the knot to the opening in the pulley, laying the knot so that it does not protrude beyond the edges of the pulley.

Then, holding on the outside the cord, the goals of the pulley, giving the cord the opportunity to wrap up on the pulley. At the second end of the cord we put on the starter’s handle and also fix it with a knot.

It is worth noting that the length of the cord is limited by the pulley and return spring. Therefore, the length of the cord should be selected in such a way that the return mechanism can without interference with the cord to the starter case, do not forget that in the main models of the lawn mowers the starter handle is put to the control handle!

After installing a new cord, check the operation of the start and return mechanism, if everything is in order set the starter in place! And do not forget, sometimes it is better to contact professionals!

Repair procedure

Features of the operation of the starter imply a sharp and gross effect, which sooner or later affects the form of breakdowns. Fortunately, in this mechanism, there is nothing particularly to break and the instructions described further affect all possible causes of malfunctions. Starting with how to restore or how to insert a spring into a chainsaw starter, and ending with the installation of dogs with a flywheel film. Step.by.step guides, sequentially, for each problem.

Restoration of the spring

The most popular case of breakdown is associated with the riding of the mounting ear of the main strip spring that reinss the cable. It is not necessary to search and buy a new spare part, since the procedure requires a minimum of time and tools. Only 2 things will be needed: source of fire (a gas burner or stove) and pliers.

Gently take out the spring from the body. You can put a slotted screwdriver.

At the site of a broken ear, you should make a new one by performing an ordinary bend of the tape. So that the metal does not burst, before the bend it must be heated red.hot and bend it to cool (it is better to do this directly above the fire).

The shape and size of the bended part should be identical to the original in order to tightly fit the restraint to the protrusion. How to tuck a spring into a chainsaw starter and save your nerves, is described below. Before starting installation, wait for complete cooling.

Typical breakdowns and repair of the chainsaw starter

The appearance of various starter malfunctions leads to the lack of the opportunity to start a chainsaw. The most frequent breakdowns of the starter include:

To eliminate each of these malfunctions with your own hands, certain tools will be required. There must be a set of screwdrivers and a spare cable with you. You need to extract and inspect the starter for the chainsaw in the following order:

• To find the cause of the breakdown, the starter from the chainsaw will need to be removed. To do this, unscrew the screws with a screwdriver with which the protective cover with the starter attached to it is held;
• After removing the lid, it is necessary to gently unscrew the screw through which the starter is attached to the protective cover;
• Then you need to try to smoothly start the starter. for this, remove the spring and clamps from it;
• Next, a coil with a cable is removed from the starter for the inspection.

As a result of the inspection, you can find a number of typical malfunctions. These include:

• Various damage to the pulley in the form of tears or cracks mainly in the back of the part. they interfere with the normal operation of the entire starter;
• Damage to the starter spring of lightweight launch. in such cases, not only the spring itself can be faulty, but the place of its fixation is the most vulnerable part of the spring;
• Damaged by the dog Starter flywheel.

A method of starting a hot engine and an engine equipped with a decompression system.

Hot engine, does not need to enrich the mixture of fuel with air, so you can start the saw without closing the air damper. The ignition is simply turned on and the starter is moved, after which the working chainsaw should be launched.

Large.volume engine, have a fairly serious compression, which extremely complicates the process of turning. To reduce the efforts required to start a large volume and power saw, manufacturers use special decompression valves, when pressed on which the compression is noticeably reduced and the engine is easier.

Valves can have different views, so study the instructions for the tool in advance.

Thus, before any type of launch, whether hot or cold, it is necessary to press this valve designed to reduce the resistance, and thereby increase the service life of the starting device.

articles, you can summarize the key points of launching the chainsaw. First, you need to start with maximum safety. Second, any deviations from the launch algorithm are not allowed. And finally, do not start a chainsaw without a starter! Consider the information from the article and use your tool correctly.

The device of the chainsaw starter

Almost all leading manufacturers of chainsaws complete their products with starters of a similar principle of action. It is no coincidence that specialized stores offer universal designs of starters that are equally successful for both Stihl, Husqvarna, Makita chainsaws, and for Chinese semi.official fakes under the named brands. Only starters of domestic production (forester, Urals and a number of others) have some features only.

The principle of operation of the starter for the chainsaw is as follows. A handle is installed in the groove of the case, through which the cable is missed. If the handle is sharply lifted, the cable is stretched, and introduces the drum of a ratchet that transfers the movement to the drum with the slots provided for the shaft. In this case, the crankshaft makes several revolutions, and the working mixture in the space between the piston and the cylinder head is compressed. Accordingly, when lowering the handle, the contact between the ratchet and the slots is lost, and the shaft stops.

With an increase in the volume of the engine, the required amount of fuel-air mixture required for its subsequent ignition is also growing, so the number of jerks for the starting cable for large power saws increases. Therefore, in order to accelerate the return of the drum, baked return springs made of steels with high elastic properties are used.

The relief of the launch of the chainsaw is realized in the following ways:

• Preliminary enrichment of the working mixture, for which there is a special damper in the design of the carburetor.
• By installing an automatic decompression valve, which provides a decrease in the working pressure in the chainsaw cylinder.
• By installing an additional spring, which during the movement of the cable facilitates the spinning of the crankshaft.
• The presence in the design of some chainsaws (for example, Partner S, Maxcut, etc.) the primer. the pump that provides preliminary pumping of the fuel.

Repair of the starter of the chainsaw

With frequent launches of the chainsaws, some starter details are constantly subjected to dynamic loads. As a result, a cable may burst, several teeth of the ratchet chill, and the shaft will turn out at a much lower speed. Therefore, the audit and even the repair of the starter. operations, sometimes carried out several times per season.

Replacement of the cord

When it is pulled, there is a constant friction of the cable about the starter case. For replacement, disassemble the hull of the node, and carefully lift the rattles in such a way as not to allow jumping from their nests of the return spring. It is better to do such work together: the assistant fixes the spring, while the cable is replaced. After fixing the cable in the handle and in the grooves of the drum, the cable is wound on the roller, and the case is assembled.

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. The elastic properties of the spring will not change.

How to put a spring on a chainsaw starter?

Placing a starter spring in the desired groove is not easy to do with an experienced user. First, the spring should be twisted to the previous diameter and installed in the cavity of the hub of the drum. The outer end of the spring is fixed for the restrictive ledge, and the external using the screwdriver should be placed opposite the holes in the lock. The loop at the inner end of the spring with a screwdriver is combined with the hole, after which the disk is lowered. The disk is checked whether the dog of the ratchet has become in place. Next is the assembly of the ratchet itself.

After installing the spring, it is necessary to adjust its tension. To do this, a cable is inserted into the groove on a circle, and a return spring is twisted around it. After eliminating the slack, it is better to wind the spring at an additional several revolutions to guarantee the required part of the part.

It is not recommended to carry out the repair of the ratchet mechanism itself at home, since many operations will require the use of CNC machine. It’s easier to purchase a new node in specialized stores.
