What is the best chain pitch for a chainsaw
What does the distance between the teeth affect?
In a saw chain, the distance between the cutting teeth directly affects its performance. The more, the deeper the cutting edge can cut into the wood, provided that the stop is sharpened correctly.
Accordingly, on more powerful chainsaws, it is permissible to install a headset with a large distance between adjacent links and vice versa.
If you put a ¼ ”saw headset on a powerful chainsaw, then the performance will drop significantly, and the load on the engine will increase, because the saw will run at a speed and exceed the maximum permissible speed, which ultimately can lead to overheating and seizure of the CPG.
And vice versa, installing a chain with a large pitch on a weak chainsaw will lead to the fact that the saw power will not be enough for normal cutting, of course, this will not entail serious consequences, as in the first case, but it is not comfortable to work with such a tool.
Also, the quality and accuracy of the cut depends on the distance between the links. The farther from each other adjacent cutting teeth, the stronger the vibration during work and the lower the cutting accuracy. For a more accurate cut, choose a saw head with a smaller pitch. This factor must be taken into account by those who are engaged in curly carving with a chainsaw on wood.
The chain pitch has a great influence on the so-called “rebound”. The greater the distance between the teeth, the more likely the chainsaw will bounce.

Important! Most often, “rebound” occurs when working with the tip of the tire, for example, when making internal cuts. In this case, you need to be extremely careful, regardless of the step with which the chain is used.
When choosing a chain, the rule is that the pitch (distance between the teeth) is proportional to the power, but the cutting accuracy is inversely related, i.e. the greater the distance, the lower the accuracy.
How to find out
There are several ways to find out the pitch of the chain:
- View the pitch value on the guide bar. Manufacturers of the saw headset must indicate the length of the bar, the width of the groove and the pitch of the driven sprocket on the shank of the saw blade.
- Measure the distance between the shanks of adjacent teeth or the centers of three adjacent rivets.
- The method that works for chains in branded packaging is to look at the characteristics of the chain on the box.
The branded packaging of Stihl chains contains comprehensive information about the products, after reading which you can find out not only the distance between adjacent links, but also the type of teeth, the width of the link, the recommended file size for sharpening.
Pitch. half the distance between adjacent shanks or between three adjacent rivets.
There are several sizes, 1/4 “is the smallest, 3/4” is the largest and 3/8 and 0.325 “are the most popular.
Step. a parameter that is available not only in the headset, but also in the sprockets of the tire and chainsaw.
Technical Tips- Identifying Chain Pitch and Chain Gauge
Important! All three elements, chain, sprocket and bar, must have the same pitch parameter, otherwise installation and correct operation is impossible.
3/8 or 0.325 which is better and why
Determine which parameter is better and which is not worse, since each of them has its own characteristics and is intended for chain saws of a certain power. Depending on how the saw head is correctly selected, the performance of the tool will have different indicators. If the headset is selected optimally, i.e. the distance between the links corresponds to the recommended power, then the performance of the chainsaw will be maximum. If selected incorrectly, the motor will experience overloads that can lead to malfunctions.
The optimal power ratings for 0.325 inches are 1.8-2 kW. It is for this reason that chains with such a pitch are used on the Husqvarna 142/137 chainsaw.
For parameter 3/8, a tool with a power of up to 3 kW is required. In this case, the question arises, why on the Stihl 180, with a power of 1.5 kW, 3/8 inch chains are used. The answer is simple: for Stihl chainsaws, power is not the most important thing, the maximum number of revolutions is of great importance. The Stihl 180 delivers over 13,500 rpm, so it can cut with a 3/8 ” headset.
For 0.404 inches, optimum power 4.5. 5 kW.
Important! The indicated values of power and chain pitch are not necessarily character, the user himself has the right to choose the parameters of the headset, which he plans to use on the chainsaw.
All you need to know about chainsaw pitch for efficient operation
There are several basic parameters for choosing a chainsaw, one of them is the pitch of the saw headset. The pitch depends on the power of the chainsaw, and greatly affects the cutting speed.
How much the step matches the power determines the performance and service life of the chainsaw. Also, the consumption of fuels and lubricants depends on its correct selection.

Based on the recommendations of the manufacturer of the chainsaw and taking into account the technical parameters from the table, you can find out the model of the chain that is suitable for your tool and avoid mistakes when buying.
How to choose
In the case when it is necessary to choose the optimal chain pitch for the chainsaw, it is best to take into account the manufacturer’s recommendations and, based on them, choose the type of saw headset.
If the manufacturer’s recommendations are not known, then you need to choose according to the engine power. We have provided the recommended values corresponding to a certain step just above.
Important! When choosing, do not forget that the distance between the links is not the only parameter that you need to pay attention to.
It is also worth choosing the thickness of the link, the type of cutting tooth, the number of links. Performance is largely dependent on the angle of sharpening, depth of cut and the shape of the stop teeth. The sharper the restraining tooth, the higher the cutting speed and the lower its quality.
Below we offer you to watch a video on choosing the pitch of the chainsaw chain. The video tells and shows how to determine it, for which chainsaws, which chain step to use.
Choosing a chain for a chainsaw: which is better?
The chainsaw chain is critical. It depends on its quality how well the work with wood will be. It is necessary to understand what types are, how they differ and which one to choose for performing certain works. At the same time, everyone who works with chainsaws should remember that chains gradually wear out. Regardless of how carefully to treat them, over time it is necessary to replace.
Now it is worth considering the main models of chains for chainsaws that are sold in Russia. This will allow you to choose the best option for performing a particular job.
They are considered “eternal”, but the price for them is quite high.
It is a renowned brand that produces some of the most reliable chains. Manufacturing company BlountIncorporation. It specializes in making headsets for professional and household chainsaws, so you can trust this brand. A special patented alloy makes Oregon chains extra strong and durable. Most of the chains are chrome plated, which also extends the service life. Special vibration suppression system reduces stress on hands while working.
The most popular Oregon chains are:
- Oregon 59 AC.
Many chainsaws come with Oregon bars and chains. And in this case, it is easier to understand what exactly needs to be purchased when the standard circuit fails.
It is an American manufacturer focused on the production of chains for professional and semi-professional chainsaws. This means that the quality of the alloy is quite high. Shot blasting at the production stage allows to achieve increased metal hardness.
The cutting links have a long edge, which makes it possible to produce a large number of sharpenings.
Chains from a Russian company are quite reliable and budgetary. They have increased durability, but are recommended for use on household and semi-professional chainsaws. If you use the chain daily for several hours, then it quickly stretches and wears out. Therefore, this manufacturer cannot boast of excellent chain properties for professional devices.
But the democratic price forces users to buy these products to perform periodic work.
This company is not a global manufacturer of chainsaw chains, but supplies several samples to the market. They usually come with branded saws. Interestingly, the chains are being developed at the Oregon factory, but under a different brand. The technology, accordingly, is also used differently: only foreign production facilities are used. Husqvarna today offers chains for household and semi-professional tools.
Thus, their cost is affordable, but the quality is not the best.
It is interesting that even with intensive use of the chain of this brand, the carved element will not stretch. This effect was achieved due to the fact that saw chains are riveted on a heated metal. Patented oil groove system guarantees an even distribution of lubricant over the entire surface, so the chain can last longer.
Here are the most popular Stihl chains in Russia:
- Picco micro mini.
These three models meet the needs of professionals and those who use a chainsaw from time to time.
How to choose a chain for a chainsaw: types, sizes, nuances
How to choose a chain for a saw with a gasoline engine step by step
Chain pitch is measured in inches. It is indicated on the product and affects the quality of the cut. The higher the saw power, the more you adjust the step. For non-professional instruments up to 2500W, standard 0.325 ” pitch.
The chain pitch must match the pitch on the drive sprocket of the engine and tire. If you change it together with the tire, replace the engine sprocket with a collapsible one and install the drive ring on it with the desired pitch.
How to choose a chain for a chainsaw according to the thickness of the shank
The shank is the part of the chain link that fits into the guide bar. Its thickness must strictly correspond to the groove of the tire so that the chain moves as smoothly as possible, the cut is smooth and there is no excessive tire wear.
How to choose a chain for a chainsaw in the shape of a cutting tooth
The choice of chain for a chainsaw should take into account the shape of the cutting tooth. When viewed along the tooth, the cutting edges form a similarity to the number 7. The rounded tooth is called Chipper, with an acute angle. Chisel.
Chisel teeth are characterized by high productivity and cutting speed because their configuration reduces the contact area of the tooth with the wood during operation. A serious drawback of the “chisel” tooth is that it quickly becomes blunt on wood contaminated with grains of sand. Resharpening such a tooth requires very precise adherence to all standard angles and parameters.
The Chipper tines have a larger cutting area with the wood and therefore lower cutting speed. But this drawback compensates for the undemanding quality of regrinding. The rounded corner of the “chipper” will tolerate sharpening errors more easily and shows itself well in working with contaminated wood.
How to choose a chain for a chainsaw in length
Its total length is determined by the number of links that make it up (it is equal to the number of shanks). The chain for one bar may not fit on a bar of the same length on another saw. Therefore, see what length the manufacturer recommends in the instructions for the saw.

How to choose the right gold chain?
Thanks to the skill of the jewelers, the gold chain has become an important style-forming element. Masterfully juggling in different genres, the masters create diverse models that combine romantic tenderness, impressive respectability, deliberate rudeness or adolescent brutality.
There are many variations of chains, but each has its own characteristics: length, width, weaving (hand, machine), metal. Without taking these parameters into account, a hasty purchase will turn out to be a complete disappointment. The chain can stab and squeeze the neck, and even worse, it can not withstand even three months of wearing.
What are the strongest chains? How to choose the optimal length for yourself? What is the best to combine with? Read about this and not only in our article.
General information about chain drives
Chain transmission refers to gearing transmissions with flexible coupling. The power in the chain drive is transmitted by means of a multi-link pivot chain from the drive to the driven sprocket, located on parallel shafts.
Application area of chain drives
Chain drives are widely used in many areas of mechanical engineering, structures of agricultural and road machines, machine tool construction, etc. They are used in machine tools, motorcycles, bicycles, industrial robots, drilling equipment, lifting and transport, road construction, agricultural, printing and others. machines for transferring motion between parallel shafts over long distances, when the use of gear drives is impractical, and belt drives are impossible.
Chain drives are most widely used for the transmission of powers up to 120 kW at peripheral speeds up to 15 m / s.
Disadvantages of chain drives
Significant noise and vibration during operation due to the impact of the chain link on the sprocket tooth when engaging, especially with small numbers of teeth and a large pitch (this drawback limits the use of chain drives at high speeds).
Relatively fast wear of chain joints, the need to use a lubrication system and installation in closed housings.
Extension of the chain due to wear of the joints and its descent from the sprockets, which requires the use of tensioners.
Compared to gear drives, chain drives transmit movement less smoothly and evenly.
Chain drive classification
Chain drives are classified according to the type of chain used. Currently, roller, bush and gear chains are used, which, in turn, can be single-row and multi-row.
In roller and bush chains, the links with the sprocket are engaged through a roller or bushing, while the durability of the chain increases, but its weight and cost increase.
Toothed chains are collected from plates, and the design of the hinge is of great importance to the performance of the chain. The design includes a guide plate to prevent the chain from sliding off the sprocket.
Compared to sleeve chains, gear chains run more smoothly, provide greater kinematic accuracy (smooth transmission). can transmit more power, have high efficiency, but their weight and cost are much higher.
The design of the chain sprockets depends on the type of chain used. Sprockets for bush and roller chains are shown in fig. 2 on the left, sprocket for the toothed chain on the right.
When and how to change the chain?
Excessive stretching of the mowing chain over the links is considered a major sign of critical wear. Both the main row and the sprocket with the tire undergo deformation, so the update should be considered comprehensively. If you only plan to replace the chain, then you should resort to trick, since it is not so easy to install new equipment of the same size on an old tire. For regular work, it is advisable to purchase a headset in three sizes. The main parameter will be the step and length. For the medium size, a format should be chosen that directly matches the characteristics of the tire and sprocket. The alternating use of multi-format chains will correct the interaction between the working bodies and the cutting teeth. This is a kind of running-in of the chain teeth by tension. The chainsaw, in turn, should be used in different modes in terms of engine speed, if such an option is provided in principle.
Other signs that should be the reason for updating the chain include mechanical damage to the teeth. Even if there is a theoretical possibility of restoring the equipment, experts recommend abandoning the elements requiring repair and switching to a new headset. By what parameters to select it, will be discussed further.
This parameter always depends on the size of the tire fitted to the machine. If you accidentally buy a chain that is smaller than your bar, you will not be able to put it on. If this element is larger than the size of the tire, you will not be able to tighten it. Both options prevent the use of inappropriate chain sizes. They are usually indicated in inches and have the following meanings: 10 “, 12”, 13 “, 14”, 15 “, 16”, 18 “and above.
The chain length is determined by the number of links. Links are connecting links that fit into the groove of the tire, not cutting teeth. When buying, you can specify to the seller either the length of the part in inches, or the number of links included in its composition. Some manufacturers, instead of the length, indicate exactly the number of links in the saw unit. As a rule, this number does not depend in any way on the thickness of the tail, the step and the height of the profile. For example, a low-profile chain with a drive link thickness of 1.3 mm can consist of 72 links, 56 links or any other number of links.
Which chain is better to put on a chainsaw
The chain is the key element of any chainsaw. The quality and speed of work when sawing wood depends on the type of cutting tool installed on the unit. For novice users of chainsaws, choosing a saw chain seems to be a difficult process, since you need to know what types of this part are, its characteristics, etc. This article will cover the main factors to consider in order to choose a good chainsaw chain.
0.325 inch pitch
This is the minimum step value, but the most common nonetheless. Saw blades with this step are usually installed on amateur and semi-professional machines with low power. in the range of 3-3.5 hp. This is enough to easily cut branches, cut thin trees, and carry out minor construction work. 0.325 inch chain runs smoothly without vibration, tearing wood, overloading the engine or fatiguing the operator.
The order of the cutting links
In most cases, the order of placement of cutting elements can be of three types.
- With a pass. A connecting link is inserted after each cutting tooth.
- With a half-pass. A connecting link is installed between each pair of cutting links.
- Standard. Each cutting tooth is secured with two connecting links.
Cutting links are the main components of a saw chain and are expensive due to a complex manufacturing process. Manufacturers, by changing the order of the cutting teeth, reduce their number and thereby reduce the cost of the finished product. But at the same time, due to missing links, the efficiency of the tool is noticeably reduced, and the chain wears out faster.
Pobedit is a very hard alloy, superior in strength to glass. Therefore, household glass cutters, various cutting locksmith and turning tools are made from pobedit, and it is also applied to the saw chains of chainsaws. Pobedit is soldered onto the cutting links, where it acts as a strong cutting edge. But despite its hardness, this alloy is brittle.
The service life of Pobedit brazed chains significantly exceeds the service life of standard cutting elements. Tungsten carbide chains are used for sawing frozen and hard wood, and for emergency rescue operations when you need to quickly cut reinforced concrete or regular concrete.
The disadvantages of carbide chains include their high cost, which is several times higher than the price of conventional cutting elements.
Chains for chainsaws with victorious soldering are very rarely used in amateur practice, since they are designed for semi-professional and professional tools with good power and high torque.
Cutting depth and profile height
The depth of cut depends on how high the chain profile is. The higher the profile, the more the chain “bites” into the material, and as a result, the productivity of the tool increases. With a low profile, thinner chips are removed, and the chain is not immersed as deeply into the material. Usually, the depth is adjusted by sewing the stoppers, which are located on each cutter.
There are the following profile sizes:
- high profile. 0.03 “(0.762 mm);
- low profile. 0.025 “(0.635 mm).
This information can be found in your chainsaw documentation. These types of profiles are installed on amateur and professional units. But you should be aware that a pro-class tool cannot always be equipped with high-profile chains, and household tools are always equipped with low-profile cutting elements.
High-profile chains are the most productive elements, which means they have increased “aggressiveness” and, in addition, tangible vibration. The latter significantly reduces labor productivity, since it does not allow working with the unit for a long time. Therefore, manufacturers have found a middle ground: with a large step, a chain with a low profile is made, and vice versa, if the step is less, then the profile is made high. These changes remove all side effects as much as possible, the unit starts to work with less “aggressiveness” and normal performance.
It’s hard to say which profiles are better. When choosing, you should always focus on the expected working conditions, hardness or toughness of wood, etc.
Saws with such a pitch are installed only on professional units with a power of at least 5.5 hp. With a saw with a pitch of 0.404 inches, you can cut trees of any thickness, and the units for this cutting element have a large torque, which greatly facilitates the work of a person.
It is important to know that the pitch of the chain always corresponds to the pitch of the sprockets, both driven and driven. It follows from this that if the documentation for the device indicates that it works with a chain with a pitch of 0.404, then you should not put the chain on the chainsaw with a pitch of 3/8. Before installing a chain with a different pitch, you need to purchase a complete kit, including both the bar and both sprockets: the master and the follower.
In addition to the above steps, there are two more: these are 1⁄4 (0.25) inch and 3⁄4 (0.75) inch. Saws with such a pitch are not very popular, both among professionals and DIYers.
Drive link thickness (tail)
This parameter is the second most important when choosing a saw blade. You should be aware that on different brands of chainsaws, the tire will differ in width. Drive links are also designed only for a certain type of tire.
Leading links are of the following sizes.
- 0.043 “or 1.1 mm. This is the smallest leading link. It is usually installed in miniature chains, which are designed for “weak”, household units that are not designed for heavy loads.
- 0.05 “or 1.3 mm. Although the difference with the previous example is not significant, the cutting element is designed for more perceptible loads. Chains with a link of 1.3 mm are most common among owners of household and semi-professional chainsaws, they are lightweight and quite reliable.
- 0.058 “or 1.5 mm. This type of saw is no less popular than the previous one, but it is already used not only in semi-professional tools, but also in professional class machines.
- 0.063 “or 1.6 mm. Chains with such a thick ponytail are more durable and are only used on professional tools.
- 0.08 “or 2mm. This size is the final among the types of leading links. The chain is designed for long-term operation and heavy loads. It is not difficult to guess that the element is used only on highly professional chainsaws with high power.
As a result, the thicker the driving link, the stronger and better the chain, and the more loads it can withstand. But, when choosing a cutting element, it is necessary to check the instructions for the device, which indicates what size the tire is allowed to be installed on it.
STIHL develops not only power units, but also separate saw chains, which are often used interchangeably for tools from other brands. This company develops the bulk of the replacement equipment on a production line in Switzerland, using the highest quality raw materials, including high alloy chromium-nickel steel, which allows Stihl products to be as strong and reliable as possible. It is interesting that even with intensive use of the chain of this brand, the carved element will not stretch (and this usually leads to the loss of all standard features), since saw chains are riveted on heated metal.
All the recesses of the connecting links are machined by means of rivets made of hardened material. The uniform distribution of oil along the STIHL chains is ensured by the company’s patented oil groove system, which are located in the profiles of the driving teeth. Top sawing accessories.
- High profile Rapid Micro model with 3/8 inch pitch with 0.325 inch links. The links are different in thickness, within the limits of 1.3-1.6 millimeters. All links are of the Chipper type. Such chains have proven themselves well on construction sites and in the agricultural sector. All the cutting edges of this replaceable element are high enough, which increases the cutting performance. The chain wears out slowly, but when it comes time to sharpen, do it simply by using special notches.
- Low-profile Picco Micro model with 3/8-inch steps. Such an element was created under the CHIPPER links with a thickness of 1.3 millimeters. Note that the chippers on this headset have different cushioning lugs. This chain is good for all kinds of jobs. She, like others in the Stihl line, has notches with which it is easy to control the level of wear of the carved element, as well as to re-sharpen when the need arises.
- Low-profile Pico Micro Mini chain with 3/8-inch pitch. This headset is designed for links with a thickness of 1.1 mm, cutting teeth type. “CHIPPER”. Please note that this type of teeth is slightly rounded, due to which the movement of these elements is smooth, this allows you to carry out a number of sawing operations as comfortably and efficiently as possible, and also guarantees a neat cut. Such a chain is installed on one or two-handed tools, lightweight models. Vibration is reduced by the beveled cutting depth gauge.

Oregon Cutting Systems
Chains from Oregon Cutting Systems, which is the representative of a larger company called BlountIncorporation. The latter is considered the leader among manufacturers of saw chains, guide sets, and other accessories (not only for gasoline tools, but also for electric ones). Oregon Cutting Systems is renowned for its patented steel alloy, which, due to its high toughness, is guaranteed to be wear resistant.
The overwhelming majority of the chains of this company are chrome-plated, as well as special notches that allow sharpening the chain (when it is unevenly worn) more efficiently and accurately. A great advantage of the products of this company, when compared with others, is the presence of an innovative vibration suppression system. In addition, both the leading and the connecting links are formed so that each of their recesses, each hole is well lubricated, and the uniform distribution of the lubricant ensures that the risk of damage to the replacement headset is reduced. Popular Oregon chain models include:
- The high profile Oregon 59AC has a pitch of 0.404 in. This model is produced with links, is 1.6 millimeters thick and has chipper teeth. This chain is ideal for those who are engaged in felling wood, as the design features of the 59AC model make it as easy as possible to cut wood (even the densest) in the transverse plane. Among the main design features: a large chain pitch, a large sharpening angle, improved quality of cutting teeth, which will not dull longer. The latter are also easy to sharpen.
- Low-profile model Super70, with a 3 \ 8-inch pitch, which is made for links from 1.3 millimeters to 1.6 millimeters, the teeth are of the “CHISEL” type. Such a carved element is a professional one, which can provide a good result when cross-cutting. The productivity of the tool is increased due to this exchangeable equipment. Additional advantages: the presence of a vibration reduction system (due to shock absorbers), the presence of microreservoirs (recesses) for lubrication.
- Low profile 91R chain with 3 / 8in pitch. This model features 1.3mm links and CHIPPER teeth. This model is suitable for longitudinal sawing and is easy to re-sharpen thanks to the optimal toothing. The same feature allows you to make more accurate cuts, to achieve accurate cutting. The depth gauge is slightly chamfered, which means recoil and vibration are reduced, which allows the operator to easily manipulate the tools.

Rating. which chain is better for a chainsaw?
Not sure which chainsaw chain is best? To deal with this issue, you need to consider their varieties, to understand the main distinctive characteristics. In addition, you need to understand that even in the hands of careful operators who use the tool carefully and devote a lot of time to preventive maintenance measures, the saw sets wear out, which means that sooner or later the issue of replacing the carved element becomes an edge.
In the modern market for power units and accessories, you will find many types of removable saw equipment, which have different configurations of cutting links, pitch, length and thickness. All this must be taken into account when choosing a carved element for a specific saw model.
Husqvarna cannot be called a developer of replacement equipment for powertrains, however, this brand has all the patents for the production of chains, as well as all the necessary technologies. This Swedish brand develops chains at the Oregon plant. Husqvarna was one of the first companies to renew its range of accessories for hobbyist and semi-professional sawing tools. According to this program, the products manufactured by the company can easily complement devices of different manufacturers, from “ELECTROLUX MOTORS” to “Partner”, etc.
Varieties and main differences
A chain with a guide bar is a removable equipment, which means, for example, when deciding which chain is better for a budget-class Stihl chainsaw, you can also consider carved elements of a different class. In other words, owners of budget gasoline chainsaws can choose a durable saw set for their tools, which is more wear-resistant.
Important! Considering all of the above, we can conclude that by changing the saw headset, the performance of the power unit increases. In a sense, this is true, but only if initially your equipment, or rather its main unit, has a power reserve, a good torque potential. Only then can you work with a longer headset, a high-quality carved element, without fear of engine damage, which usually results in expensive repairs.
- the quality of the material from which the chain is made;
- chain length;
- chain pitch;
- the thickness of the replaceable headset;
- groove features;
- features of the links (there are two types in total).
For a number of characteristics, branded and budget chains differ significantly. Nevertheless, some operators of fairly powerful budget gasoline saws manage to combine the unit with a perfect saw set produced by Oregon, Husqvarna, Stihl. If you believe unofficial data, recently, Hammer models, as well as Power Sharp, have taken the leading positions in the ratings of consumer demand for such products.
The higher the price range, the more likely it is that the proprietary chain compensates for the technical imperfections of the tool by improving work results even when performing complex sawing operations, due to an increased repair resource, due to the stability of a number of operational characteristics.
Popular interchangeable headset models
Model H25 belongs to the profile class. Main characteristics: pitch. 0.325 inches, links of the “CHIPPER” type, their thickness is 1.5 millimeters. This saw element provides high performance of the device if it has a cylinder with a volume of no more than 60 cm cubic. In terms of application, such a chain can be called universal due to the beveled “heel” and the innovative Low Vib technology, a system that not only reduces vibration, but reduces the level of chain elongation.
H42 high profile 3/8 “pitch, all teeth of this set are” CHISEL “. The main feature of this replaceable element is that it can be installed on a tool, the volume of the cylinder exceeds 60 cubic centimeters. The “heel” of the chain is chamfered, the anti-vibration system is well implemented here. Re-sharpening the model is simple.
Based on the main characteristics of the power unit and on the features of the guide rail, it is easy to choose the ideal carved element using such a rating.
