How To Shorten A Chainsaw Chain With Your Own Hands

What tools will you need for home repairs?

You can carry out the work using the most accessible tools. Depending on the skills and abilities, you may need:

  • Vice;
  • Angle Grinder;
  • A hammer;
  • Chisel;
  • File;
  • Beard;
  • Pliers or passages.

Some craftsmen also use an electric welding machine. It is not recommended to use it, since the seams after welding quickly deteriorate under the influence of vibration during intensive operation of the chainsaw. This method is only suitable for gear chains that transmit forces to the drive sprocket.

Why does the chain stretch on a chainsaw?

The chain on any chainsaw stretches over time, this applies not only to budget models, but also to well-known brands such as “Stihl”. This process is facilitated by the following reasons:

  • Poor adjustment of the oil pump. Leads to improper oil flow, increasing metal heat during sawing.
  • Felling and construction in adverse, extreme conditions. Particles of dust, dirt or sand get on the links of the headset and act as an abrasive material. Gradually wipe the joints.
  • Use of waste or low-quality oil with m metal particles.
  • Installing a new headset without adjusting the adjusting bolts after each use.
  • Reducing natural tension after long and intense work.

Stretching the chain is normal for a saw headset. It can be controlled using the recommended oil manufacturer, following the rules for operating the tool. Failure to pay attention to the tension can lead to tool breakage, decreased productivity, and dangerous injury during operation.

What to do when the chain is stretched?

Linking links

  • Install the link with new rivets on the chain. Lay on the anvil, open side up.
  • Put the top plate on the rivets, tap several times with a hammer for a tight connection.
  • Attach the barb to the rivet, make 1-2 hard blows with a hammer. Achieve pronounced thickening, flattening of the metal. Repeat the operation on both sides of the link.

After work, you should check that the chain is movable, all its elements move freely in different directions. This avoids jamming during sawing.

DIY chain shortening

You can also shorten the chainsaw chain with your own hands using simple tools. This method is less reliable, but easy to use, does not require special skills in working with riveting equipment. Disadvantage. you cannot control the strength and quality of crushing rivets. This can lead to tool breakage under severe stress.

How to properly dress and tension the chain?

Gloves should be worn before starting work to avoid cuts on sharp teeth. You can only pull on a cold chain. after cooling it can burst from overvoltage, damaging the mechanism. Remove the protective cover from the chainsaw, carefully put it on the tire.

Depending on the configuration of the tool model, tension is applied manually or using a special regulator. In the first case, you need to loosen the bolts on the bus, after installing the chain, apply tension using a slotted screwdriver. If there is an adjusting bolt, turn it as far as it will go until there is sufficient blade tension. After work, check that there is no sagging, be sure to tighten it after the first use.

Repair errors and their consequences

The quality of work to shorten or increase the size of the chain on a chainsaw depends on adherence to the technological process. Major mistakes:

  • The new element of the headset does not match in pitch, thickness or size of the teeth;
  • Installing the element in the wrong direction;
  • The chain does not match the length of the bar;
  • The rivet is loose or crooked.

Violation of the operation scheme can lead not only to damage to the tool, but also to dangerous injuries. You should carefully check each element of the headset even before you start sawing wood.

Rivet punch

It is a mechanical device similar to a conventional press. The package includes an anvil, grooves for fixing the saw headset with different tooth pitch. For convenience, there are interchangeable rivet extrusion tips. The tool is only intended for separating links.

Instructions: How to shorten a chainsaw chain with your own hands at home?

The chain is considered a consumable for a chainsaw. often than other elements fail and begin to sag, especially with frequent use. With intensive work, the metal of the links begins to heat up, which leads to stretching of the saw headset, a decrease in tension. To avoid planned replacement, the chain can also be shortened at home. The procedure is simple to implement, but you need to know how to properly remove the rivets and reassemble all the components.

Criteria for self-selection of a saw chain

In everyday life, the quality of removable sawing equipment from leading European brands is highly valued. Stihl and Husqvarna brand guide bars and chains enjoy unofficial reference status.

When purchasing a product, you must make sure that the model in terms of length, pitch and thickness of the shank meets the design standards of the chainsaw. The entire chain assortment is divided into five size groups ranging from 1/4 to ¾ inch.

Small-cube models of budget-class chainsaws are equipped with products with a smaller pitch, chains with an increased pitch and thickened shanks. a characteristic feature of the headsets of powerful and productive professional chainsaws.

Possible causes of spontaneous saw chain breakage

How To Shorten A Chainsaw Chain With Your Own Hands

If the chain on the chainsaw breaks, it is necessary to find out the cause of the malfunction, establish the expediency of repairing the damaged part or installing a new one.

Typical reasons for saw chain breaks are unfavorable external factors:

  • Excessive tension;
  • Wear of the guide bar or inconsistency of the shanks with the width of the working groove;
  • Operation of the saw set with large constant loads;
  • Overheating of the headset due to lack of lubrication;
  • Inconsistency of the chain with the type of tire and configuration of the crown of the drive sprocket.

How to eliminate the risks of acquiring a low quality counterfeit

When buying a branded chain on the market, the risks of acquiring a Chinese chain counterfeit are not excluded. The task of self-selection is complicated by the lack of a reliable way to distinguish a high-quality branded original from a fake, which is an order of magnitude inferior in terms of work resource to branded products.

Features of home renovation

Many experienced users prefer to do their own chain repairs. The success of the work performed is determined by the presence of special skills and tools, knowledge of the structural features of models for various purposes.

In particular, dismantling and assembly of wear-resistant analogs does not create any difficulties. Only apply carbide to the cutting edges of the saw links. Regarding connecting elements and rivets, standard metal is used for their production.

With more or less success, you can rivet a chainsaw chain at home, and if you have the right tool, even in the field. Please note that special care must be taken when using a self-refurbished headset. At the first opportunity, a repaired connection in a hospital is desirable.

The initial stage of repair and restoration work

All known methods for shortening a saw chain assume criteria for rejecting damaged cutting and connecting links, a sequence of working steps determined by the technology. Cutting and connecting links are assembled with factory rivets, which in all characteristics comply with the current standards.

The use of homemade components is not recommended in any case. Special rivets for chains are extremely rare on sale, so in most cases the problem is solved by installing the necessary parts removed from the dismantled section of the chain.

Repair standards and restrictions

Recommendations for fixing worn out rivets by electric welding do not take into account changes in the metal structure from even short-term high-temperature effects of the welding arc.

An angle grinder seized by welding or heated with an abrasive wheel, the connecting elements of the chain are less wear-resistant, which significantly affects their reliability.

  • The tight connection of adjacent links is accompanied by additional loads on the engine and the kinematics of the chainsaw.
  • The lack of a smooth running of the chain makes it difficult for the headset to enter the cut, the possibility of back blows and other traumatic moments is not excluded.
  • “Overtightened” and loose connections of the repaired chain are more susceptible to breaks during a sharp drop in loads.

The simplest machine for repairing chainsaw chains justifies its cost by the ability to completely rivet a damaged chain in a short period of working time and restore its performance at a level of up to 90%.

Chinese-made chainsaw chains are essentially copies of European models, so the above repair recommendations are valid for the entire Chinese chain range.

Range of saw chain repair machines

A special machine for riveting chainsaw chains is included in the list of working equipment of specialized workshops. The offered assortment includes several budget and branded models of imported production.

Riveting machines of Stihl, Husqvarna and Champion brands are characterized by increased capabilities and comfortable level of work.

Technically sophisticated devices ensure high quality riveted joints, saving labor time and material costs.

How and how to shorten the chain on a chainsaw: recommendations of professionals

Situations are not uncommon when, when installing a shorter bar on a chainsaw, you also have to change the saw chain. This information will tell you how to shorten the chain on a chainsaw in such a way that the part is fully used up. Alternatively, it is possible to fit a long chain to a shorter standard guide rail.

For repairs, non-stretched chains with a relatively small resource development are used, which received partial damage when breaking or hitting cutting links on metal inclusions contained in the wood.

Feasibility of self-repair

Experts advise to rivet and repair the damaged chain with minimal loss of quality, using the technical potential of the service workshop.
Despite the assurances of the manufacturers about the problems and complexity of self-repair, a significant part of users prefer to master the methods of restoring the working capacity of saw sets on their own.

The reason for this phenomenon:

  • Accommodation of the owner at a great distance from service points;
  • The high cost of the repair services provided by the services;
  • Lack of required equipment.

It is not advisable and unsafe to compensate for the natural wear of the chain by shortening. Operation of the saw headset with an extended chain is inevitably accompanied by:

  • Forced wear of the tire and the rim of the drive sprocket;
  • Increased engine load;
  • Increased risk of injury when sawing work of different levels of complexity.

How to shorten the chainsaw chain yourself

If you have a summer cottage, or you live in a private house, then most likely there is a chainsaw in your arsenal of garden accessories. This device is a great helper for anyone who has a garden on their site. Quite often, the owners of such devices are faced with the problem of how to shorten the chainsaw chain on their own. This problem is especially urgent for villagers.

Required tools

Well-known chainsaw manufacturers like Champion and Goodluck advise against making chain reduction at home. But if you have the skills to work with power tools, then such manipulations are quite easy to carry out. For. To shorten the chain take the following:

  • Vice;
  • A hammer;
  • File;
  • Beard;
  • Pliers;
  • Electric welding machine (for some saw models it may not be needed).

The below shows the main nuances that you need to pay attention to when shortening the chain on the saw.

Manufacturers

It must be remembered that every chainsaw needs careful and regular maintenance. After prolonged use, there is a need to shorten the chain. The most common manufacturers of these garden tools are:

  • Stihl;
  • Champion;
  • Goodluck;
  • Husqvarna.

Before using the saw in your area, carefully read the instructions for it.

Equipment and rules of use

A chainsaw usually comes standard with about three chains and two tires. It is advisable to turn the latter over every 3 hours of tool operation. After the same time, most saw manufacturers (Stihl, Husqvarna, etc.) advise changing the chain. If you follow these simple rules for using power tools, you will avoid frequent breakdowns and permanent repairs. But most do not adhere to all the recommendations, as a result, they need to take the saw to the master or do the adjustment on their own.

After a long time of operation, the chain must be pulled. If you do not know how to properly make such a repair, then it is better to seek professional help. The basic principle of tensioning a dusty chain is shown in the photo below.

When you notice that this no longer helps and the mechanism inside the saw does not give the necessary stretch, you should shorten it. If you do not do this, then the drive sprocket may deteriorate in the chainsaw. Such a strong stretch of the chain occurs when actively using the file. If it is not changed or shortened, then you will have to buy a new tool, which is much more expensive.

Why stretching occurs?

Quite often, the problem can arise that the chains are stretched and need to be shortened. So why is this important saw element stretching:

  • Most often, such a nuisance happens due to the fact that the chain itself is of very poor quality. Fakes from thin and cheap materials have flooded the domestic power tool market;
  • But there are other reasons for chain stretching. One of them is a poor-quality assembly of the file mechanism itself. Because of this, the chain is constantly overheating and stretching;
  • If you want to prevent the chain from shortening, then check that the oil supply to the driven sprocket is adjusted. When using the saw, make sure that the mechanism lubrication hole is not clogged with sawdust and debris. In addition, remember that every saw needs regular maintenance and periodic adjustments;
  • In some cases, the sprocket will wear out resulting in severe chain stretching. A similar reason occurs due to the passage of the protrusions that direct the movement. As a result, there is strong friction, which provokes stretching.

A chainsaw is a must-have for everyone who has a summer cottage or a private house. But if you want it to serve you as long as possible, then it is necessary to periodically carry out in-line repairs and debugging of all mechanisms. Particular attention should be paid to stretching the chain. Before use, it is advisable to carefully read the instructions, which describe the basic recommendations for using the file.

Required tools

Chainsaw manufacturers claim that it is impossible to shorten the chain at home, since the very technology of their manufacture is very complex and requires high-precision equipment. Practice shows that nothing is impossible. In order to shorten the chain, you need:

  • Vice;
  • A hammer;
  • File;
  • Beard;
  • Pliers;
  • Electric welding machine (in some cases, you can do without it).

How to shorten the chainsaw chain yourself?

Almost every owner of suburban housing has a chainsaw in stock. And we don’t even have to talk about the inhabitants of rural areas: such a tool is a vital necessity for them. And it requires a chainsaw to take care of itself and timely maintenance. All service rules are clearly spelled out in the instructions.

Consult an experienced welder

The question may arise about the advisability of repairing the chainsaw chain, since the consequences of its repair can be so serious. But this is all only because of inept welding. An experienced welder will do this work quickly and efficiently, which will reduce the likelihood of negative consequences to almost zero. And when using rivets without subsequent welding, the previously mentioned moments simply disappear. The only question is where to get such rivets. But making them is not so difficult if you have a lathe available.

How to remove rivets?

The main parameters of the chainsaw chain.

Chainsaw chain is difficult to disconnect. The rivets are made of high quality steel and have a geometric shape that does not allow you to simply knock the rivets out of the link. The inner part of the rivet has a larger radius. On this thickening, the link turns, and the outer parts of the rivets have only a connecting function, so it is enough to simply securely fix them on the outside of the chain. The rivet is removed as follows: the chain is fixed in a vise, and the protruding part is grinded. When sewing, we try not to damage the side parts of the links.

It is not recommended to use an angle grinder, as the parts will heat up very quickly, which will lead to a change in the physical properties of the metal. It is better to use a file or file for grinding. Seam is done on both sides of the link. Now the rivets can be knocked out of the chain using a barb, slightly bending the side parts of the links.

Chainsaw tooth device diagram.

It is also profitable for trading organizations to sell chains in their finished version than small parts for repair. For these reasons, it will be very difficult to find a suitable rivet with the required geometry. Making it at home will be even harder, so you have to use an old rivet.

As you may have guessed, the chainsaw chain will have to be disconnected twice. Do not forget to count so that the number of guide lugs on the inside of the chain and the distance between these lugs match with the chain saw drive sprocket. If you are shortening the original chain, then this is not necessary. And if this is a chain from another model of a chainsaw, then everything needs to be measured and calculated very well. A deviation in the chain pitch (even a small one) from the parameters set by the design will lead to the fact that the chain will stretch again in the shortest possible time (at best) or break the chain saw sprocket. The tire will come to an end, as the driven sprocket will quickly overheat.

Negative consequences of improper chain repair

The considered option of repairing the chain is not the most reliable, since no one guarantees you the high quality of the final product. The following consequences of such a repair are possible:

Chainsaw chain sharpening scheme with a file.

  • During welding (especially at a low current), excessive heating of the circuit elements was made, which caused a change in the physical properties of the metal. Soft metal will allow the chain to stretch not along its entire length, but at the point of welding. The chain guides will shift, and other elements of the chainsaw (sprocket, tire) will quickly fail.
  • The welding depth is greater than planned. The inner part of the rivet was welded to one (or more) parts of the link, which became a violation of the mobility of the links. The consequences will be the same as described in the first case.
  • Welding quality is poor. In this case, a circuit breakdown may occur during its operation. The fact is that the chain in operation experiences very high lateral loads, so unreliable welding will quickly “work out”. The possibility of injury will be very high.

How to make the right rivets with an electric drill?

Chainsaw chain structure.

Do not be afraid: no one offers you to buy a machine. Use a conventional drill. The whole process of making rivets using an electric drill and a conventional file will be described as follows. From a nail, the diameter of which is equal to the diameter of the inner part of the rivets (check with a caliper), a workpiece is cut out. a piece about 7 cm long. This workpiece is fixed in the head of the electric drill. The drill itself must also be securely fixed.

Two files are fixed on a wooden beam, the distance between which will be equal to the width of the inner part of the rivet. You may not be able to do this quickly, but you must be absolutely precise. It remains only to organize a uniform supply of the bar to the workpiece. We recommend using a piece of board, one end of which we fix to the stationary part of the workbench using a wide door hinge, and on the second end of the board we fix a bar with files.

We check the perpendicularity of the location of the files and the workpiece. and you can start working. Turn on the electric drill and smoothly lower the files. They will make grooves on the workpiece. It is not recommended to make rivets in one go, since it is not worth overheating the metal, but it is necessary to control the thickness of the workpiece on the machined part. A too thin part of the rivet can damage you too, so you need to achieve maximum accuracy. If you were able to do everything correctly, then all that remains is to cut the rivet and use it to connect the chain links.

It is better to cut the rivet by hand, without using an angle grinder. Do not forget that when cutting metal at high tool speeds, a significant increase in the temperature of the material will occur, which is very undesirable. The finished rivet is in no way inferior to the factory product in quality, so the restored chain will serve for a long time. Negative moments when using homemade rivets will be practically eliminated. The main thing is that when installing the rivets, you do not forget to align the side parts of the links (after all, they had to be unbent when separating the chain). Even a slight protrusion of these elements from the design standard will lead to premature wear of the drive sprocket.

READ  The chainsaw does not start the candle is wet

It is recommended to make several rivets at once as described earlier. The point here is not only to stock up on such necessary elements for future use (although this is also important). The most important thing from the total number of products is to choose the most suitable size: any deviation from the norm will make the chain vulnerable at high loads.

The use of remanufactured chains is not recommended when working with dense wood species.

Linking links

If all the parameters of the chain are combined with the parts of your chainsaw, then you can start connecting the links. We connect the links to a rivet, pressing their side parts tightly. It will no longer be possible to rivet the protrusions, since they are grinded flush with the links. We’ll have to use electric welding. For this, the electrode must be taken of the smallest diameter.

Determination of chain wear: a. wear of teeth, b. installation of an additional fixing plate on the key link.

It is not recommended to start welding immediately, as it is a very delicate job. Practice doing this first on other details. So you will at least roughly understand at what current you need to cook and what welding time to choose. And the electrode will become shorter, which will allow welding more accurately. A very short period of time is enough to “grab” the rivet. After training, we weld the rivets to the lateral parts of the link. It remains only to grind off excess metal on both sides with a file and the chain can be considered ready for use.

Equipment and rules of use

The saw kit must include several chains (minimum. 3) plus 2 bars. It is recommended to turn the tire over after 3 hours of operation. After another 3 hours, the chain is replaced. Such simple rules can significantly extend the life of all the elements of the chainsaw. And in life we ​​practically do not adhere to recommendations and are guided by our own ideas about expediency.

Comparative table of characteristics of chain chainsaws.

After a certain time of operation of the chainsaw, we simply tighten the chain. And at a certain moment we notice that the tensioning system no longer allows the chain to tighten. The chain is stretched to the limit. You cannot continue to work with it, since the stretched chain will begin to break the drive sprocket, as a result of which the tire wear will greatly increase. The chain must be shortened.

Another reason why you have to shorten the chain is to “fit” a longer chain from another chainsaw to your tire. This is also common, as there is an opinion among users that better chains are made for “professional” chainsaws.

Why are chains stretched??

This happens due to the fact that the oil supply to the driven sprocket is not adjusted. It may happen that the oil supply hole is clogged or the adjustment is incorrect. The chainsaw needs periodic maintenance and adjustment.

The chains also stretch due to wear on the drive sprocket. It turns out that on the worn sprocket there is a slip of the guide protrusions. Parts with such friction are very quickly heated, hence the reason for the stretching of the chains. In practice, the same happens when the chain tension is low. The conclusion suggests itself: it is necessary to replace the drive sprocket, chainsaw tires, adjust all elements. Otherwise, the problem will only get worse: the chainsaw will start to work in jerks, the chains will continue to stretch, the engine will fail (with a very high degree of probability).

This is especially true if you are using a chain that has undergone restoration.

Rivet Removing Machine

For disassembly, a specialized machine is used. a punch. The machine is designed as a small mechanical press. In its lower part, a removable anvil is installed, which has grooves of different sizes. The working rod of the device also has nozzles of different diameters. This makes it possible to use the machine for chains from different manufacturers. The rivet is removed by squeezing it out of the seat.

How to shorten a chainsaw chain with your own hands. procedure

Often during the operation of the chainsaw, the saw chain stretches, which makes it impossible to further use the tool. Today there are specialized workshops that provide services for shortening chainsaw chains, but it is possible to shorten the chainsaw chain with your own hands at home or right at the workplace.

Tools that you need to shorten

You can properly shorten the chainsaw chain with your own hands using special tools.

Rivet removal methods without the use of specialized devices

There are several ways to remove rivets without using specialized tools:

  • Grind off the protrusions on the emery. When using this method, it is necessary to control the degree of pressure on the rivet in order to avoid damage to the working parts.
  • Cut with the cut-off wheel of an angle grinder. It should be borne in mind that in this case the metal heats up, which will affect its properties.
  • Saw off the heads with a file or file. With this method, the risk of link damage is minimized.
  • Chop down using a chisel. Before starting work, you will need to securely fasten the chain in a vice.

After the outer protrusions are completely cut off, you will need to knock the rivet out of the seat. To do this, you need to choose a punch, the diameter of which will correspond to the diameter of the hole. The punch must be placed on the rivet and knocked out with a sharp blow with a hammer. After completing these steps, the chain will be disconnected.

Caution: To avoid damage to the links, secure them securely. In addition, the punch should be installed strictly perpendicular to the rivet cut.

Rivet setting machine

After disassembling and removing the chain element, the working links must be reconnected. For this purpose, a riveting machine is used. The assembly process takes place using a special work roller, which is driven by an electric motor.

The rivet is clamped between the stationary anvil and the work roll. The operator independently sets the pressure of the work roll using the adjusting screw. During the rotation of the roller, the edge of the rivet is gradually crushed, which makes it impossible to detach the links from each other.

Reference: using machines to shorten the chainsaw chain allows you to bring the build quality as close as possible to the factory sample. However, these devices are quite expensive, and their purchase for home use is unprofitable. In addition, it is not always possible to use specialized devices right at the workplace. In this regard, shortening can be performed with improvised tools.

Reasons for chain stretching

A chainsaw chain, regardless of manufacturer, can stretch for several reasons:

  • Incorrect operation of the oil pump. Insufficient oil supply leads to overheating of the chain and its rapid stretching.
  • Natural wear and tear. Occurs as a result of prolonged use of the tool.
  • Use of poor quality lubricant.
  • Violation of the rules for operating a chainsaw.

Important: If any irregularities in the operation of the oil pump are detected, it is necessary to eliminate the malfunctions, ensure normal lubrication of the saw blade. Failure to do so may result in drive sprocket failure. You should also pay attention to the quality of the oil. The presence of various types of abrasive microparticles in the oil is not allowed.

How to rivet a chainsaw chain

To assemble the chain, you will need to install a repair link on it. It must be borne in mind that its dimensions must strictly correspond to the dimensions of the working links. Installing a spare part with a different pitch or profile can damage the drive sprocket, driven sprocket and saw blade of the chainsaw.

The repair link comes with rivets that you just need to fasten. To do this, place the chainsaw chain on an anvil. After that, put the punch on the new rivet and flatten the head with a sharp hammer blow. Riveting is necessary until the resulting thickening covers the hole in the outer plate.

When flattening, control the degree of clamping of the side plates. After assembly, the installed link must move freely along the axis. Installing a chain with a jammed link on a chainsaw is not allowed. Failure to follow this rule can lead to more serious damage to the device.

Some people use electric arc welding machines for assembly. In this case, the rivet edges are welded to the outer link plates. The use of electric welding involves heating the metal to a high temperature. As a result of overheating, the properties of the metal change, it becomes less wear-resistant.

Recommendation: after assembling and installing the part on the chainsaw, you need to check its performance with a minimum load. Only in case of normal operation can the load be increased.

From the information described above, it follows that chain stretching on a chainsaw is a fairly common phenomenon. It is quite possible to shorten the chain at home, you just have to enlist the traditional tools that are available to almost every owner.

If it becomes necessary to shorten

Often in the forest or on a remote construction site, you will not be able to find a replacement for your extended chain.

After taking into account all the tips, and making sure of the need to shorten the chain, it is important to know the sequence of actions and possible replacement methods.

There are not so many of them and depend on how many links need to be removed, and in what conditions the repair will be carried out.

Each link (cutter and links connecting them) has two such rivets. In case of damage to nearby “native” connecting links, you can use elements from any other similar chain of any, even automotive, equipment. You just need to adjust the profile with a file, especially from the bottom, where it has a small groove.

Chainsaw chain diagram

The easiest way is to take a long chain, in which you can remove several segments without any problems. So, at least, it becomes possible to use the native links. They are removed with a hacksaw for metal, but it is better to use emery.

Initially, you need to grind off unnecessary rivets, and then cut off the excess area. To do this, you need to pry off with a knife and knock out rivets from unnecessary links using a homemade punch.

READ  How to Deliver Ignition From a Chainsaw

Is it always necessary to repair the chain?

Chainsaw chain slack is not always a reason to repair it. You must first make sure that it is completely not subject to tension (adjustment).

Here are some typical cases:

  • Chain stretching.
  • Inconsistency of the new existing circuit with a short bus.

Chain stretching due to prolonged use is typical. During operation, the metal of the chain heats up, and the links are gradually stretched due to the expansion of the metal in volume. That is, the chain stretches every time, which can sometimes be eliminated by partially reducing the cutting time. However, this is not an option when she has to work intensively all shift in industrial conditions or when preparing firewood for the winter.

Another circumstance that does not allow normal operation of the saw, even with a new chain, is the discrepancy in length. This can happen only when inattentive users buy, or is caused by the lack of the required chain at the moment. Which, in principle, is not so dangerous, since you can always find a way out of the situation by manually shortening it. In this case, the strength of the connection of the chain links will remain at a sufficiently high level.

Chain tension adjustment

Chains are usually tensioned manually using the saw tensioning bolt located in the area of ​​the bumpers.

Using a straight screwdriver installed on the bar and the drive sprocket, the chain is gradually tightened after closing the side cover.

It is not worth pulling the chainsaw chain all the way, as you risk stretching the links again soon. Usually a small amount of chain pull is left, checked by hand. It should give in slightly to bend off the tire by about a millimeter.

How to shorten a chainsaw chain with your own hands: sequence of actions, nuances of the process and instructions

The condition of the chainsaw must comply with the technical requirements of its operation. Any defect, be it slack in the chain or deterioration in the quality of the cut, often occurs due to its stretching.

From the point of view of operator safety, further operation of the chainsaw is not permissible. At the most unexpected moment, a sagging chain can break and injure him. Replace with another spare chain or have it shortened in the workshop or at the workplace.

Chain selection taking into account tension

There are no specific solutions in this regard. You just need to remember about the complex wear of the chainsaw equipment itself. You should either change it entirely during prolonged operation, or take care of extending the service life of its main part, that is, tires and sprockets.

The performance of the chainsaw will be longer only in an additionally completed composition in the form of several chains. Professionals, in particular, do not neglect this circumstance and purchase an additional bar and (or) several chains with the saw.

Here’s how you can shorten the chain on a chainsaw:

We connect the links

After checking all the parameters, you can connect the links. A rivet is used for connection, the lateral parts of the links are tightly pressed. Electric welding is used to “grip” the rivet. The file is used to remove excess metal. The chainsaw can then be used.

How to shorten a chainsaw chain with your own hands?

It is safe to say that almost every private house has a chainsaw, especially if you are a person who lives in a private house or has a summer cottage. As with any other instrument, you need to treat it with care. Many owners face a typical problem. the chain stretches due to prolonged use. The reason for this is the heating of the metal, after which it increases in volume. We will find out how to shorten the chainsaw chain with our own hands, because you can simply make a mistake with its length when buying. The most important thing is that after such a procedure, the connection of the chain links will remain the same strong.

How to shorten a chainsaw chain with your own hands

Removing rivets

It will take effort to disconnect: high-quality steel is used to make rivets, their shape is geometric.

To remove a rivet, you must:

  • Fix the chain in a vice.
  • To grind off the protruding part, for which a file or file is used.
  • The rivets are knocked out, for which you can use a beard. The side parts are slightly bent.

After disconnecting the part, do not get rid of the removed rivet. It is possible that a replacement will never be found. It’s almost impossible to buy a rivet, but you may have to use it.

If the repair is done incorrectly

In the event that the repair of the chainsaw chain with your own hands was performed poorly, the following consequences are possible:

  • During the welding process, the current was low, which led to excessive heating of the circuit elements. This changes the physical properties of the metal.
  • In deeper welding, the inside of the rivet is welded to several parts of the link. As a result, they become motionless. All this also leads to disruption of the work of other elements.
  • If the quality of welding is poor, the product may break during operation. This is due to the large lateral load acting on it during operation. In this case, the user is likely to be injured.

Cooking tools

Although the manufacturers claim that shortening the chain at home is impossible, there are craftsmen who can do it. To do this, you should acquire:

  • In a vice;
  • With a hammer;
  • Beard;
  • Needle file;
  • Electric welding machine (not always required);
  • Pliers.

Chain repair

To repair the chainsaw chain, you need to assemble and disassemble it. Let’s take a closer look at these stages in order to understand what is to be dealt with.

How to avoid stretching the chain?

Before deciding what to do if the chain on a chainsaw breaks, it is better to familiarize yourself with the main causes of breakdowns:

How to shorten a chainsaw chain with your own hands?

How to avoid stretching the chain?

Before deciding what to do if the chain on a chainsaw breaks, it is better to familiarize yourself with the main causes of breakdowns:

  • The drive sprocket can also stretch the chain. In this case, the guides slip, friction and heating of the parts occurs.

Cooking tools

Although the manufacturers claim that shortening the chain at home is impossible, there are craftsmen who can do it. To do this, you should acquire:

  • In a vice;
  • With a hammer;
  • Beard;
  • Needle file;
  • Electric welding machine (not always required);
  • Pliers.

If the repair is done incorrectly

In the event that the repair of the chainsaw chain with your own hands was performed poorly, the following consequences are possible:

  • During welding, the current was small, which led to excessive heating of the circuit elements. This changes the physical properties of the metal.
  • In deeper welding, the inside of the rivet is welded to several parts of the link. As a result, they become motionless. All this also leads to disruption of the work of other elements.
  • If the welding quality is poor, the product may break during operation. This is due to the large lateral load acting on it during operation. In this case, the user is likely to be injured.

We connect the links

After checking all the parameters, you can connect the links. A rivet is used for connection, the lateral parts of the links are tightly pressed. Electric welding is used to “grip” the rivet. The file is used to remove excess metal. The chainsaw can then be used.

It is safe to say that almost every private house has a chainsaw, especially if you are a person who lives in a private house or has a summer cottage. As with any other instrument, you need to treat it with care. Many owners face a typical problem. the chain stretches due to prolonged use. The reason for this is the heating of the metal, after which it increases in volume. We will find out how to shorten the chainsaw chain with our own hands, because you can simply make a mistake with its length when buying. The most important thing is that after such a procedure, the connection of the chain links will remain the same strong.

Removing rivets

It will take effort to disconnect: high-quality steel is used for the manufacture of rivets, their shape is geometric.

To remove a rivet, you must:

  • Fix the chain in a vice.
  • To grind off the protruding part, for which a file or file is used.
  • The rivets are knocked out, for which you can use a beard. The side parts are slightly bent.

After disconnecting the part, do not get rid of the removed rivet. It is possible that a replacement will never be found. It’s almost impossible to buy a rivet, but you may have to use it.
