Which chain for saw is better.
How to choose a chain for a chainsaw?
Professionals know that not power makes the saw a good tool, but a way of operation, handling it. And if you follow the chainsaw correctly, it will last ten years and will always show excellent cutting qualities. If the tool is not correctly handled, then even the newest saw, bought for a lot of money, will not want to work at all. And most importantly, what the cutting qualities depend on is the attitude to the chain. It must be properly operated, constantly undermined and, of course, choose the right. Chain. An important element of a chainsaw. And if the engine, even with poor circulation, will perform its work for tens of hours, then the incorrect operation of the chain will lead to the impossibility of work in 10 minutes. So, we learn to choose and care for the chain correctly.
One. Marking chains for chainsaws a step.
The very first thing where the choice of chain for a chainsaw begins is to understand what type you need. The main criterion for classification of chains is a marking relative to the step. The chain step is the distance between the nearest teeth (tails) or between the three rivets of the chain. It is measured in inches and the most popular sizes: 0, 325; 0, 375 and 0, 404 inches. Each type is intended for its needs, and the choice here may be attached to read the instructions for its chainsaw. After all, each saw is immediately developed under a certain step and only professional saws can work with all three types depending on the place of work. To better understand these types, consider them separately.
Before starting, say, another important point: each type of chain is designed for certain capacities of chainsaws and twisting moments. After all, the smaller the step, the less productivity of the chain and you need less effort to move along the wood. And the more the step is, the higher the productivity and you need more strength for work. In addition, the step affects the so.Called “aggressiveness” of the saw. It means not only performance, but also the ease of control. Speaking in simple words, the greater the step, the more the chain “tears” the wood “tears”, which means that it requires more effort to keep the tool. In addition, the larger step of the chain is more dimensions of the links, which means that the incision will be wider, which similarly requires large power costs of the tool. Therefore, buying a chain with a big step for a low.Power chainsaw is not at all practical, you can just “kill” the saw. Think about it! And smoothly proceed to the consideration of specific sizes.
This is the most minimum in the voiced size and often the most common. After all, domestic and semi.Professional, low.Power chainsaws are the most popular among the people, and this chain is for them. Recommended power under the chain 0, 325. 3 liters. With. Or no more than 3.5 l. With. If your chainsaw is more powerful, you can think about the chain for 0, 375 inch. But everything still depends on the tree and the place of work. If the saw is used for cutting branches and rolling of non.Weed trees or construction work, then 0, 325 inches will be more appropriate. This chain makes the work more smooth, comfortable, not so “tears” the wood at the beginning of the saw. And for a person, as well as the engine, such work for these purposes is more appropriate.
Why did we write two digits? It’s simple if 3 divide by 8 get 0, 375. And the parameter in the form of a 3/8 fraction is very often used for marking. The reason is ordinary so as not to confuse numbers 0, 325 and 0, 375, so we are not surprised if the chain is 0, 375 is hard to find, it is better to look at the 3/8 marker immediately.
The chain with a marking 0, 375 is less popular with brand 0, 325 and is used on chainsaws with a capacity of 4 liters. With. Such a chain is already operated on a roll of relatively non.Weed trees and for cutting wood of medium thicknesses. For their group of unprofessional and professional types of saws, this is the most optimal size.
Chain 0, 404 is used only on professional saws. The power of the tool for working with such a chain should be at least 5.5 l. With. Only in this way will the chainsaw be able to show all its qualities of high.Speed strong tools. And such a chain can already easily saw and bring down huge trees. From this it is also clear that for weak saws to use a chain 0, 404 is not profitable. In addition, chainsaws under the chain 0, 404 are distinguished by an increased spinning moment, without which it will be difficult for a person and a tool with such a step.
Summing up now is not difficult. The main selection criterion is indicated. This is a marking relative to the step. It is not difficult to understand what is needed in this regard, it is enough to open the instructions of your chainsaw or simply compare the power relative to the above information. But do not forget another important point. The chain step must match the step of the leading and led sprockets (led, often part of the tire). That is, if your saw is intended for size 0, 325, then installing a chain 3/8 will not be so easy. Together with a new chain, you need to buy a new leading star and a new tire, otherwise it will be really impossible to work (we repeat, it is impossible due to the difference in the step of the stars). And the latter, we listed three types of chains relative to the step, there are actually five of them (another 1/4 and 3/4, that is, 0, 25 and 0, 75 inches, respectively), but due to low popularity, especially in everyday life, we will keep silent about two other types.
Now we move on to other important issues to learn how to choose a chain for a chainsaw and professionally understand this topic.
Classification of chains of chainsaws by tail thickness.
The thickness of the tail or more precisely will say the thickness of the leading link. The second parameter of the characteristics of the saw chain. Many perhaps do not know, but the groove on the bus has different width in different chainsaws, similarly and leading links are designed for different tires. They are characterized by five sizes: 1, 1 mm, 1, 3 mm, 1, 5 mm, 1, 6 mm and 2 mm (0, 043 ”, 0, 05”, 0, 058 ”, 0, 063” and 0, 0, 0, 0, 08 ”, respectively). Consider each separately.
This is the most minimum and use such miniature chains only on low.Power household saws. For loads and hard work, such a chain is not calculated.
This size, although not too different from the first, is able to withstand heavy loads. And it is this type of chain that is the most popular in the world. Clocks with a ponytail of 1, 3 mm are used not only on high.Quality reliable household chainsaws, but even on semi.Professional devices. Such chains are light and reliable at the same time and most likely, the reader will have to choose this particular type.
The effect of the parameters of the leading star and the number of engine speeds on the speed of the saw chain
When choosing a chain saw, gasoline or electric, consumers are usually interested in the power of the saw, the length of the tire. Questions about the leading star are very rare and even less customers are asked about the linear speed of the chain. We will try to figure out the speed of the chain, t.To. It directly affects the performance, ease of sawing, cleanliness of the surface of the cut of wood, show the parameters of the leading star that determine it and what consumer properties of the saw need to pay attention. The article will have enough formulas from physics. Whom they strain, miss them and move on to the final part of the article. Who is ready to understand carefully, welcome to joint research.
In the instructions for the operation of the saw and on the sites you will hardly find information about the torque of the saw engine, about the parameters of the leading star. Find the value of the engine speed at maximum power, the speed of the chain will be even more difficult. Only well.Known manufacturers from Europe and Japan indicate these values, including STIHL.
Different Chainsaw Chain Types
Let’s calculate the linear speed of the chain ourselves, and compare the result obtained with the data given in each instructions of the chainsaw of Shtil and answer the questions
TOP 5: Best Chainsaw 2020
- Which saw is more manufacturer.
- How does the step of the chain and the leading sprocket affect the speed of the saw chain.
- How does the number of teeth of the leading sprocket affect the speed of the saw chain.
To calculate the linear speed of the circuit measured in [m/s] (we will indicate units of measurement in square brackets), we need to know the engine speed, the number of teeth of the leading star and the chain step. Suppose that the file of the saw has engine speed of 9000 [rpm], the step of the chain and sprocket ⅜ “, the number of teeth of the drive gear 6. In one second, the saw engine will mark the leading star 9000/60 = 150 [rpm]. Accordingly, the leading star with 6 teeth will spell 1506 = 900 chain links per second. We remember that each leading link in the chain has a length of 2 ⅜ “or 2 0.375 = 0.75 [“]. About determining the step of the chain was written in this article. Then the distance that the link links in 1 second is 9000.75 = 675 [“/s]. We know that 1 “= 25.4 [mm] = 0.0254 [m]. We get the linear speed of the chain equal to 6750.0254 = 17,145 [m/s]. On pages 49, 50, the operating instructions for the chainsaw of the STIHL MS 180 chainsaws indicate that the maximum saw power is reached at 9000 [rpm], and the linear speed of the chain is 18.6 [m/s]. Therefore, the discrepancy in the calculations and data specified by the STIHL will amount to 1.455 [m/s] or 7.8%.
Deeper the physics of the process and clarify the value of the speed of the chain.
Find a textbook, a primer in which it would be described how to determine the linear speed of the chain of the chainsaw. We will be based on the theory of calculating chain programs.
Knowing the design of the gearing of the chain and stars, we see that the links of the chain that are engaged with the teeth of the asterisk are located around it in the form of the sides of the polygon. In this case, the vertices of the polygon correspond to the centers of the rivets of the links of the chain in the engagement. For one revolution of the leading star, the circuit moves to the value of the perimeter of the polygon, in which the sides are equal to the double step of the chain P, and the number of the parties is equal to the number of teeth z Stars. Then the centers of the chain hinges when gearing with the teeth of the asterisk are located on the dividing circle of the asterisk, diameter D which is determined by the formula:
Counting gives us the following result D = 2 ⅜ 25.4 / sin (3.1415 / 6) = 38.1 [mm] (1 “= 25.4 mm). Accordingly, the radius R = 19.05 [mm] = 0.01905 [m].
Remember from physics that V = ωr, where
V. Linear speed of the chain, [m/s];
V = ωr = 9000 2 3.1415 0.01905 / 60 = 17.95 [m / s].
The discrepancy in the calculations and data specified by the STIHL will amount to 0.65 [m/s] or 3.5%, which is permissible during engineering calculations.
Properties of wear.Resistant chains of general and special purposes
The types of chains of household and professional class intended for working with wood are distinguished by the quality of the material lasting the resource and the cost. The diamond chain unique in terms of wear resistance is intended for concrete.
One of the options for choice may be a wear.Resistant carbide chain. The overhaul resource of such a product is an order of magnitude higher, but for its sharpening it needs special equipment that allows you to sharpen the cutting links at different angles, respectively for the standard transverse and for longitudinal sawing.
The carbide chain is designed for productive sawing of solid wood and light building blocks. It should be borne in mind that when working on aerated concrete or foam concrete, the resource of the saw set, even the most prestigious brand decreases by 2-3 times.
The thickness of the shank
It is she who determines the width of the cut. Where it is necessary to create minimal cutting resistance, for example, in battery saws, use a chain with a thickness of a tail of 1.1 mm (Husqvarna X-Cut SP21G circuit). In chain saws, for private users and semi-professional models, the thickness of the tail of 1.3 mm (Husqvarna X-Cut S93G and SP33G circuits) is used, and in professional saws-the thickness of the shank 1.5 mm (Husqvarna X-Cut C85 circuit).
It directly affects the performance of sawing. The teeth of the chains of powerful professional saws have a form of type “chisel” (Chisel) and look in the projection as the number “7”. They are ideal, for example, for industrial rolls of trees (in the photo below-the Husqvarna X-Cut C85 chain).
Teeth in the form of “chisel” (chisel)
For pruning branches and using saws by private users, we recommend more rounded forms of cutting teeth such as “Semi Chisel”, such as the Husqvarna X-Cut SP21G, S93G, SP33G chains.
Husqvarna X-Cut P33G They cut less aggressively, but more safe and not so demanding on the purity of wood.
Micro-chisel chain (0.325 ″; one.6 mm; 1848 links) Oregon 22LPX100R
This model is purchased for chainsaws with an engine volume 35-60 cm3. The chain is due to the rectangular side faces of the angles of the cutting link with special strength and performance. Thanks to the shock absorbers, the return is practically not felt.
- Light sharpening due to indicative risk;
- The return is 20% lower than that of analogues;
- Lubrilink connecting links and lubriwel shank holes save oil and evenly distribute it across the bus.

How to understand what chain your saw has
First, carefully inspect the chain. On chains of serious manufacturers, the manufacturer’s brand will be engraved or knocked out (see. Photo 3.4). If there is no brand chain, be especially careful when working, t.Anything can happen to the chain and the user can get injured. In addition, in photo 3, 4 you see numbers on the saw, in one case 2, in the other. 6. We turn to the table and understand that in the photo 3 chain with a step of 0.325 “, and in the photo 4. ⅜” p. Figures 5 and 3 are knocked out on the leading link. The number 5 suggests that the thickness of the leading link is 1.5 mm, and the number is 3. 1.3 mm. Therefore, in photo 3, a chain with parameters: a chain step 0.325 “, a link thickness 1.5 mm, marking. 25, then there may be the first letter P or R, the second letter M or S. In the photo 4. The step of the chain ⅜ “p, the thickness thickness is 1.3 mm, marking 63 and similar letters from the previous example. Having calculated the number of leading links, we unequivocally determined the parameters and labeling of the chain.
We draw your attention to the fact that The chain should be good and properly sharpened. Determine that the chain must be hidden, you can by the size of the chips formed during sawing (if the chips are finely dispersed as flour, then the chain must be sharpened) and the user’s increased effort when sawing (saw with a well.Sharpened chain saws under its weight, the operator only supports the saw and does not put pressure on her). We will talk about the rules for sharpening the chain separately.
How to choose a chain for electric saw
It is required to understand how to choose the right chain. There are several factors that affect the choice. The characteristics should be completely suitable: the chain step, the thickness of the leading link and the number of links. Otherwise, the product will not be able to install on a saw set.
The table will help to understand how to choose a chain step. This distance between three neighboring rivets and is measured in inches.
|¼||It is used in short circuits, a small power. They can only be used to solve household problems. This size is not very popular, so in Russia there were few options for drinking ¼|
|0.325 and 3/8||This is the most popular step that is used in most cases. The saw is even and smooth. It is recommended to perform household and semi.Professional tasks|
|0.404 and 3/4||It is used for professional tasks where it is necessary to use the saw for a long time without a break. The links are large, necessary for gross saws|
What is a chain step
The number of links
Manufacturers can offer the same model with a different number of links. Therefore, the name is not an important parameter. It is much more important to look at leading links.
The links of the chain
Today there is a classification of the thickness of the leading link.
- 1.1 mm or 0.043 inches is used for low.Power saws;
- 1.3. 1.5 mm or 0.05. 0.0578 inches is considered the most popular size that is used on almost all saws;
- 1.6 mm. 2 mm or 0.063. 0.08 inches are used at high.Power saws that are necessary on the forestry.
How to sharpen correctly?
In order to make the correct sharpening of the main types of chains, you need to sharpen a round file. Depending on the size of the link, the diameter of the file is selected from 4 to 5.5 mm. This method is good for experienced owners who can definitely withstand the angle of inclination when sharpening.
So that there is no use of the file to the side, it is better to use a machine for sharpening chains of chainsaws.
What should be the procedure? For this you need:
- Install a file in a clamp at an angle of 25-30 °.
- Fix the machine on the saw bus so that the file is touching close to the cutting edge of the tooth.
- With light pressure, 3-5 movements are performed with a file. If the cutting edge of the tooth is spoiled by a nail that fell in the log, then the movements must be made more.
- After the tooth is sharpened, the mobile carriage in which the file is clamped is diverted, and the chain moves to the next tooth. Then the process is repeated.
- After one circle is passed, the angle of the file in the clamp changes mirror, and the teeth that have reverse sharpening are pulled.
After that, the height between the cutting limiter and the upper edge of the cutting tooth is checked. If it is less than the permissible value, then the restrictive tooth is grinding on top of a flat file, which restores the depth of the cut.
The main manufacturers producing the best chains are STIHL and Oregon. When buying products of these brands, you will provide yourself with the maximum quality. Good chains also go under the Husqvarna brand. True, they themselves do not let them out, but order from the same Oregon. Well, quite rarely now there are chains from Dolmar. Also good quality chains.
There is also a large layer of brands under which inexpensive Chinese chains are sold. These are, for example, Rezer, Champion, Forza and many others. They stretch faster and dull than the previous options. But nevertheless, they also have the right to life, since they are inexpensive, and at the same time they are fully coping with their work.
Chain for the chainsaw STIHL which is better
Like the chainsaws themselves, and the chains for them differ: purpose, quality, shape of the cutting surface, link and step size, and other parameters.
Chain for the chainsaw of the Shtil. Which is better?
A short answer to this question is better the one that is suitable specifically for your saw model and has the best indicators of cutting force among other equal. For example, it is believed that Tree chain. This is STIHL Picco Duro (this is STIHL chains with winning attacks). They work at least 4 times longer than ordinary chains. This was checked with a cut of logs with concrete inserts, Super tooth chain STIHL He completely retained his performance after 10 cuts of such wood.Intensive material, while the usual chain failed, not even mastering 3 full cuts.
How to choose a chain for a STIHL chainsaw For periodic work in a private house/in the country? For the most popular models of the MS 180 type, 0.375 ″ P Picco Micro (1.3 mm) by 50, 51, 55, 56 links are suitable. There may be another length. If you buy a coil in the bay, which then rivets into the chain of the STIHL cutting machine.
Which chains are better for chainsaws for cutting bushes and generally comfortable cutting? The same 0.375 ″ Picco Micro is suitable, only 1.1 mm thick (used on models MS 170, 180, 211, 230). Be careful. For a narrow chain, also purchase a tire of appropriate narrowness so as not to worry the headset, tire and planting nest.
Which saw chains are better for felting forest? 0.375 ″ P Picco Super (1.3 millimeters). This is the choice of professionals in the work of forest harvesting, which every day, from year to year, are the trees. In this chain, teeth are ideally suited for the tasks of the workpiece even thousands of cubic meters of forest per month, because:
- Made in the form of a bit;
- Provide a smooth move;
- Give a reduced level of vibration;
- The rebounds do not generate due to the smoothness of cutting into a tree;
- Give a clean cut surface.
Which chains are better for oak, and, in particular, to perform figured cut? It is no secret that it is oak that is the favorite material for the performance of wooden products due to its strength, elasticity and natural resistance to drying out. For this purpose, take 0.25 ″ Rapid Micro Spezial (1.3 mm), which has a shortened upper line of teeth, which minimizes the incision efforts to cut.
Everything, even The best chains for chainsaws, They need lubrication. Lubrication is carried out by chain adhesive oil, which is specially designed for chains of chainsaws. “Adhesive” means that it has a high surface adhesion coefficient (“liqueness”). In this case, this is necessary that at high speeds of the chain, oil remains on it, and not spray around due to centrifugal force. The lubrication of the chain is necessary:
- To reduce friction of the chain with the leading and led stars;
- To maintain the quality of free rotation of individual links of the chain;
- To avoid overwhelming metal, which in this case completely or almost completely loses its main working properties.
Since the oil facilitates sliding, it is strictly impossible to use the machine “worked out” for lubrication. It contains a large number of small fractions of the metal, which only leads to an increase in friction and the Rapid failure of moving parts of the saw (this may be dangerous for health).
Even solid tooth chain we wear out, not to mention ordinary chains made of relatively soft metal. Professional lumberjacks know that the current chain’s flow should be optimally carried out every 2-3 fully spent gas tanks (this does not mean complete sharpening, just the current braid). To do this, there are special manual files for the saw chains and the STIHL machines that make automatic tiles with manual supply and fixing the chain. The chains with solid heaps on teeth are best sharpened on machines, because manual sharpening is long and requires a lot of effort.
Original or analogue?
First of all, you need to deal with perhaps the most difficult aspect of the choice: to give a lot of money for a chain from such eminent brands as STIHL, Husqvarna or Oregon, or save on consumables, giving preference to a less promoted manufacturer. No matter how much I want, but the unambiguous answer will not work here. It all depends on your personal capabilities, goals and objectives:
- The branded chains, as a rule, are characterized by higher quality manufacturing and have different know-how, for example, a special form of teeth. In practice, this gives an enlarged working resource and the ability to better perform complex cuts. Therefore, if you have a significant amount of difficult work (viscous or wet wood, many knots, etc. D.) or it is necessary to make not elementary straight cuts, it is better to give preference to branded equipment.
- Analogue chains attract, first of all, more affordable price, however, the reliability and constructive complexity of them, as a rule, below. If you use a saw only periodically to perform small volumes of simple work, for example, for sawing Apple trees in a suburban area, then the headset from budget brands may well be enough.
Thus, take into account the nature, complexity and volume of tasks for which the chain is acquired. In most cases, this rule is enough to make a rational choice. Of course, proprietary products are preferable. But the solution always remains for you.
Sharpening for a different type of saw
In the vast majority of cases saw used for the transverse saw of wood. In other words, the chain cuts wood fibers across. Which chain for a chainsaw is better cut along? The one whose cutting edge has an angle of inclination 5-15 °. It does not get stuck in the material and cuts significantly even more.
You can rewind the chain to a new angle, but it is more advisable to purchase the latest. In an unpleasant case, when sharpening, you will have to remove a lot of metal from the cutting tooth.
The cutting links of chains that belong to the middle and high price segment are equipped with 2 shanks, which, accordingly, affects their value. A cheaper headset is a bandwidth and a semi.Sales type.
In the samples of the bandwidth, all additional elements are located after the cutting parts. In saw cloths that belong to a semi.Sailor type, connecting elements are located after 2 pairs of links.
In standard models of bandwidth or semi.Sales type, the total number of saw links reaches 50.40, as well as 37.5%. Thanks to such a simplified design, this headset costs much cheaper compared to models in which each individual link is equipped with a pair of shanks. However, due to a simplified design, on cheap chains, during sawing wood, the load directly on the link itself increases. As a result of this, such a headset must often be hidden.
This indicator depends directly on the total number of links. Most domestic and foreign manufacturers indicate in the documents to their products such parameters as the length and total number of links.
Professional class chains design
The saw set, which belongs to the professional class, is divided into two types of reference configuration:
With a cheese configuration, the links in the context are similar to the number 7. Thanks to this structure, high performance is provided even during complex wood sawing work.
The disadvantage of the cheese models is that it is difficult to hide them manually with a file, because even with a slight deviation of the angle of sharpening, all the advantages of seven.Based profiles are reduced to zero.
In chipper models, the link is made in the form of a sickle. Thanks to this form, the area of contact of the chain and wood increases significantly, which ultimately increases the additional load on the engine. Files with chipper links have a good level of performance. They steadily perform their work even with severe surface contamination.
The material from which
In the manufacture of standard saw chains, high.Quality and durable chromichelic steel is used. For sawing frozen wood or wood with high density, it is recommended to purchase equipment with a carbed link, in the manufacture of which it is used to win.
Wins is a solid alloy that has a good margin of strength. This alloy is often used during the manufacture of glass cutters and turning tools. Win can be applied to the saw chain. This alloy is soldered to the links themselves and plays the role of the cutting edge.
Which chain for a chainsaw is better
Users of devices with gasoline engines can buy products of the most famous brands. Answer exactly the question about which chain for a chainsaw is better, you can only know what operating conditions will be when using a headset. Team Vyborexperta.RU recommends the best models taking into account the sphere and intensity of application:
- STIHL 36120030050. For work on assembling houses from logs and timber;
- Makita 531291656. The choice of communal services;
- Husqvarna C85. For work on a roll of forest, exhaust;
- Elitech. For a summer residence, garden care in a personal plot;
- Husqvarna SP33G. Choosing a home master.
All models are worthy of user attention, but only the most reliable have received the status of the best equipment in their class.
The geometry of cloves
Links can have not only different sizes and thickness. When choosing, it is important to consider the geometry of these parts. Exist Two profiles of teeth:
- Chipper (“sickle”). Thanks to the sickle form of teeth, the saw acquires a high level of performance, quickly and simply tightens and does not require the ideal geometry of angles. The disadvantages of this design include increased load on the device and reduce the cutting properties of the chainsaw.
- Chizer (“Seven”). Such details are often used on a professional tool. The disadvantages of these teeth are difficult to sharpen and Rapid wear due to the dirty mud.
How to choose
In the case when it is necessary to choose the optimal step of the chain for the chainsaw, it is best to take into account the recommendations of the manufacturer and already based on them to choose the type of saw.
If the manufacturer’s recommendations are not known, then you need to choose by engine power. The recommended values corresponding to a certain step, we provided a little higher.
It is also worth selecting the thickness of the link, the type of cutting tooth, the number of links. Productivity is more dependent on the angle of sharpening, the depth of the cut and the shape of the tooth of the limiter. The more acute the restrictive tooth, the higher the cut rate, and below its quality.
Below we suggest watching a video about choosing a chain of a chain of a chain. The video tells and shows how to determine it for which chainsaws, which chain step to use.
We tighten the circuit of an electric saw
Undoubtedly, the quality of the equipment is significantly reduced after time, since the tree is not the softest raw material, and the cutting surface has a tendency to gradual decrease in performance. During unprofitable teeth, they will completely lose the initial form and they will have to completely replace them, which will require the highest financial costs.
It is worth considering that the condition of the teeth is necessary for constant control, since there is no certain time of damage to parts. The dull detail can be easily determined by the quality and size of the chips.
Of course, you can turn to a professional sawmill master, who will do work without a doubt better. But, a more budget option would be independent processing with special tools.
- The file is flat, adjusting the restriction of the depth;
- Frame that determines the angle;
- Round part with oriented stripes;
As a rule, the chain is inserted into the tire fixed in the vice, the corresponding file is selected, which is suitable for the diameter of the teeth. The first tooth must be noted to avoid a repeated sharpening circle.

To extend the life of the tool, it should not be used on other materials, except for wooden surfaces! Why should you monitor the absence of third.Party metal objects in wood (nail, bolt, brackets). Regular lubrication of the circuit and checking the device for overheating are recommended.
It is better to use high stands when working with a tool, in order to avoid contact of the tire with the soil. It is necessary to accurately observe the intervals of the work regime of equipment. Observing the given simple rules, you can significantly extend the service life of an electric “assistant”!
