Modern electrical engineering stores today present a large assortment of various models of electric chain saws to the buyer's choice. In order for your desires to be fully satisfied with the purchase, you must choose very carefully, evaluating various characteristics. So that the choice does not disappoint you, you need to heed the advice of professionals.
For simple carpentry work, a chain saw is more convenient to operate than a gasoline saw, the big advantage of an electric saw is the complete absence of harmful emissions.
Chain saws are equipped not only with an electric drive, but also with a gasoline engine (chainsaws). But today we will talk about electric models. Having become familiar with the main technical specifications, you can easily make your choice, and the purchased chain saw will serve you for a very long time and regularly. In order to better understand what will be discussed, first we will get acquainted with the principle of operation of such a saw and its device. And then let's move on to the question of how to choose an electric chain saw and what characteristics to pay special attention to.
Brief description of the chain saw device and the principle of its operation, functions
The GARDENA chain saw is equipped with an optimized weight balance.
The design of the chain saw includes a body part, a motor (electric motor), a chain, a guide bar, and there is also a compartment for the location of the oil pump and the oil itself. On the body of the saw there are buttons responsible for turning on and blocking, a comfortable handle and a protection shield (safety). More modern and improved models also have a special handle, with which the degree of chain tension is controlled.
As for the principle of operation of this power tool, after the motor (engine) has started, rotation begins to be transmitted to the gearbox, sprocket and then the chain and the sawing process begins. Since the size of the width of the chain with cutting edges is higher than the fixed bar itself, during operation it does not jam in the material being processed.
A power saw is a portable power tool powered by electric motor. Most modern power saws are universal tools that can help in solving various household tasks. Let's look at the device of electric saws, the features of their independent choice and practical application, and also get acquainted with the rating of the highest quality modern models.
Power saw device - what does the tool consist of?
Almost all electric chain saws that are now on sale have an almost identical design. Their device consists of the following main parts and mechanisms: 
- electric motor powered by a network with a voltage of 220 volts;
- removable tire and chain with an asterisk - a saw set responsible for sawing wood;
- chain tensioner and tension level regulator - mechanisms that allow you to adjust the tension of the saw element without using tools;
- lubrication system - a set of parts and mechanisms responsible for the distribution of lubricant to the tire and chain;
- chain braking system - consists of a safety relay and a protective shield that prevents the operator from injury during a kickback;
- handles for convenient work with an electric saw;
- power cable;
- direct drive or bevel gear - the first mechanism is provided if the saw motor is located in a transverse position. The second mechanism is equipped with saws with a longitudinal arrangement of the motor.
The conclusions of experts and practical indicators confirm that a more reliable and convenient option for operation is a chain saw with a transverse motor. Its design is much better balanced, making it less tiring for the operator to work with.
What are electric saws - types and description
Today, electric saws are used not only for gardening, but also as assistants in various household, repair and construction tasks. Depending on the scope and functions, these types of electric saws are distinguished:
- chain saws - tools of this type are used for summer cottages in order to care for trees and harvest the required amount of firewood for heating. The working element of such saws is a saw set, which includes a tire and a chain. There are also garden band saws on the market, the working body of which is a steel band instead of a chain. If necessary, various attachments for an electric saw can be used to work with chain and tape tools, which will allow you to cut metal or foam concrete;
- circulating electric saws - among their main advantages, maximum cutting accuracy stands out. Because of this, circular saws are often used for the home for the manufacture of various wooden and metal parts. Tools of this type can be used to cut wood, metal, PVC and other materials;
- jigsaw electric saws - tools of this type are designed for precise figured sawing of laminate, wood, PVC pipes and metal. Among the features of such electric saws, high fluctuations of the cutting part should be distinguished. Due to this, when using electric jigsaws, longitudinal and transverse cutting of materials can be performed;
- reciprocating electric saws - equipment of this kind allows you to repair and cut in hard-to-reach places. Reciprocating electric saws can cut not only wood, but also metal or foam concrete;
- electric hacksaws - equipment of this kind in form and function is very similar to the tools of the previous type. The only difference between them is that hacksaws are more powerful and durable, which allows them to be used for cutting harder materials.
Each of the listed types of equipment is represented on the market by models with different characteristics. Powerful tools are suitable for use in industry and construction, while smaller models with more modest performance can be successfully used in everyday life.
Choosing a power saw for gardening and other household purposes is a rather difficult task, especially if the buyer does not have the experience and necessary knowledge. To choose the right tool that will meet your specific requirements, you should consider a number of key factors. Their list includes:
- engine power - the higher this parameter, the larger the equipment will be. As a rule, a saw with a power of 2 kW is optimal for domestic needs, but one should not forget that the tool motor must have a certain power reserve. This is required in order to avoid excessive loads on the motor of the device;
- the presence of a soft start function - at the time of starting the saw, it is affected by maximum current leading to increased engine wear. The soft start option allows you to avoid this and extend the life of the saw;
- chain brake - this mechanism allows you to avoid a kickback when the saw set comes into contact with the surface being cut;
- an automatic lubrication system is a set of elements and mechanisms whose main task is to distribute the right amount of oil to the saw bar and chain;
- 12 Volt battery - the presence of this element allows you to temporarily use the tool in places far from a direct power source.
In addition to all the above options great importance has the availability of spare parts for the selected electric saw. In most cases, finding replacement parts is easy, as brushes, gears, and other Consumables almost universal, and suitable for completely different power saws. Nevertheless, there are still tools on sale, the malfunctions of which can only be eliminated using exclusively original spare parts.

Proper operation and care of the power saw are the most important factors on which the life of the tool you choose depends. The instruction manual and a number of factors, adhering to which, you can work with the equipment without worrying about its breakdown, can help with this. The basic rules for using a saw include:
- sharpen the saw chain regularly - this will create a minimum load on the tool motor. Chinese electric saws suffer especially from working with a blunt chain - because of this, their engines overheat almost instantly;
- store the power saw correctly - this issue will be especially relevant for batteries, which should be stored only in a warm and dry room;
- in no case do not use the saw with strong voltage drops in the network - some models of equipment are not equipped with a protective relay, which will lead to instant overheating and failure of the saw motor. Especially often, all the same Chinese saws suffer from voltage drops;
- operate the saw only in a dry area away from sources of water and moisture.
Compliance with all of the above recommendations will help you avoid sudden repairs of your equipment and unnecessary financial costs.
Which motor arrangement in the electric saw is better, longitudinal or transverse?
When choosing an electric chain saw, draw an imaginary straight line along the tool bar. If the engine is placed along this line, it is a saw with a longitudinal engine. Opposite the motor is mounted perpendicular to this imaginary axis, then you hold the saw in the palm of your hand with transverse arrangement engine. The layout and structure of such engines are different, which, of course, affects your electric saw in different ways, its productivity and comfort.
Regarding the transverse to a different longitudinal arrangement of the engine, there are many different opinions and not theories, so let's say right away: neither one nor the other electric saws are effective, not convenient in work, alas, some nuances when choosing, nevertheless, should be taken into account.
The main guideline when choosing for yourself is the answer to the question: for what purpose do I need an electric saw? If you are going to climb trees, cutting down branches or sawing trees not bushes in the garden near the house, then this is what you need to take a narrow, not compact saw with a longitudinal motor location. Like oil, it is more convenient in any hard-to-reach places, maneuverable is not comfortable. This is a well-thought-out straight tool that will not resist if you tilt it to saw at any angle in any plane - horizontal, in other words vertical.
On the contrary, your goal is sawing logs, with the aim of then chopping them for firewood, then feel free to take an electric saw with a transverse motor, as oil is somewhat cheaper. This arrangement of the motor (across), more traditional, is not used more often. The crosscut saw is light, which reduces the load on the back during work, and of course, it is always more powerful, not fast, but speed is not productivity - an important thing that gaming slots have. Undoubtedly, such a saw is used to form the crown of trees, but get ready for the fact that the transverse motor will touch the branches.
The convenience of working with an electric saw is influenced by many different factors, the main ones where we will try to consider.
The right balance is the key to easy work
A perfectly balanced tool is one whose center of gravity is exactly in the middle. Operate with a power saw right balance– sheer pleasure: it doesn’t “lead to the side”, you don’t have to strain your hands all this time, improving the weight distribution of the tool. Electric saws with a longitudinal engine arrangement are distinguished by such a correct weight distribution. Their design is essentially a straight line: here is a hand for you, but a narrow saw is a direct continuation of the hand, in addition to the vector of the direction of force. This is as convenient as possible during operation and does not give wide room for maneuvers; it is more convenient to work with such a saw both vertically and not at the right angle.

Comparison power saw Makita In this video case, we will look at the 2nd electric saws Makita s longitudinal Not transverse.
For saws with a transverse motor, the axis of the motor is perpendicular to the bar of the saw, so the center of gravity is shifted. Because of this, there is a slight imbalance during operation - you have to constantly keep the balance of the saw.
Power is essential for successful sawing
If the saw does not have enough power to cut, this is a big problem. Therefore, it should be noted that with the same motor power, saws with a transverse and longitudinal motor behave differently. The reason for this is the different design of the engine.
For electric saws with a longitudinal arrangement of the engine, a bevel gear is installed in the gearbox. The cost of transmission of this kind is that it does not transfer the full power of the engine to the saw bar, partially eating it. Coefficient useful action(efficiency) - reduced to 85-90 percent. With saws with a transverse motor, this problem does not exist: the side motor guarantees 100% transmission of its power.
Based on this: a rip saw with a power of two kW will transfer 1.7-1.8 kW to the chain, depending on the manufacturer. And a saw with a transverse motor of the same power will transfer all the declared 2 kW to the movement of the chain, so it will cut faster and better.
It is worth noting that some leading European brands (for example, the German Bosch) do not produce saws with a longitudinal motor at all due to loss of power during sawing.
Which saw is more reliable and durable?
The traditional transverse motor design is simpler, it does not have a complex bevel gear, which is needed in order to rotate the axis of rotation by ninety degrees.

As practice shows, in a simpler saw gearbox with a transverse gear, the gears work more reliably than in an angle gearbox, which is installed in a longitudinal engine. Thus, crosscut saws are more reliable and enduring, they are less likely to break the motor and have a longer service life.
But, at the same time, keep in mind that the reliability of the motor directly depends on the manufacturer. It is clear that a high-quality German electric saw will a priori be more reliable than a cheap Chinese model, regardless of the location of the engine.
The weight of the tool is also an important factor.
Since saws with a transverse motor have a simpler gearbox, they are much lighter in weight. It is clear that it is more comfortable to work with a light saw - in the process of work, the back is not so tired.
In addition, there is some psychological nuance. The fact is that the weight of the cross saw is located closer to the body of the working person (the motor is on the side and closer to us), and therefore during operation there is a feeling that the tool is about twice as light as the same with a longitudinal engine.

How to choose a chainsaw - what to look for when buying and examples of good options
The chain saw has long been popular as a tool for small sawmills. To refuel it, you do not need to buy expensive fuel, as for gasoline analogues, but it is very convenient in operation. This is a great option for short-term sawing of firewood or cutting branches, and the tool is always in sight, and you just need to connect the plug to the outlet to get started.
How to choose a saw with enough features and not overpay extra? We will try to answer this question by considering the main characteristics of the quality tool.
An electric saw helps to cut a small amount of firewood
Do you need an electric saw?
Before you start watching certain models, you must determine if this tool is right for you. It can be completely different about chain saws - someone likes it, and someone doesn't. In most cases, the negative ratio is due to the wrong choice of tool type. For example, an electric saw is unlikely to cope with many hours of felling trees - this can only be done with the help of a professional chainsaw. The presence of a cable is another disadvantage of an electric tool that ties it to a power source. However, an electric saw can be your indispensable assistant in several cases:
- if you prefer to work indoors - house, barn or garage. In confined spaces, the use of gasoline-powered tools that emit exhaust fumes can be hazardous.
- if you just don't want to pollute environment exhaust from a gasoline engine. In this regard, the electric saw does not pose any threat - it is the most environmentally friendly tool.
- if the amount of work on the site is small, and the cutting tool is not required regularly.
- if there are no problems with the length of the cord and the presence of an electrical outlet.
The device can be used indoors
In the presence of the above factors, you can proceed with the selection of a suitable power saw.
How to choose a chain saw by engine power
Read:
Engine power is the first thing to pay attention to. This characteristic can vary considerably, but averages 1000-2100 watts. Not only the performance of the saw depends on the power, but also its durability. Assess voltage stability in electrical network, and if its jumps are frequent, you should prefer a more powerful device. This is because when the voltage drops, the motor will not be able to produce rated power and, as a result, quickly overheats.

The choice of electric saws depending on the location of the engine
AllInstrumentovy.ru will tell you about the types of chain electric pellets and their use. Header link:.
With electric parma M, you don't have to worry about voltage stability
If the device of the electric saw provides a thermal control system, the tool simply turns off, if not, a short circuit and breakdown of the tool may occur. By the way, having this unstable voltage system is also not a panacea, since the saw will be turned off too often, which significantly reduces work productivity. So the more powerful motor you choose, the less you have to worry about mains voltage. For example, the universal electric saw "Parma M" with a 2 kW engine does not lose its performance in the range of 198-224 V. Such an electric saw receives only positive reviews About work.
Is the engine design transverse or longitudinal?
The choice of an electric saw may also depend on the location of the engine in the structure. With a transverse position, when the axis of the engine is perpendicular to the tire, the center of gravity of the saw will be shifted. There will be a slight imbalance at work, so the balance of the saw will have to be constantly aligned. Longitudinal location engine more convenient. The whole structure will be a flat line, which gives the saw great maneuverability and allows you to position the bar when working at different angles. The longitudinal engine is equipped with a Gardena CSI 4020-X saw, which is perfectly balanced and therefore comfortable to work with.

Chain tension adjustment
Caring for an electric saw necessarily requires adjusting the chain tension. Sometimes, when the chain starts to sag, it needs to be pulled. Most often this is done with a wrench that twists the nuts. However, in today's modern STIHL MSE 140 C-BQ models, it has a convenient chain tensioning system. To do this, there is a lever on the side panel of the case that allows you to easily adjust the tension.

Soft engine start
When starting and braking the engine, a shock dose of current occurs through its winding, which does not have the greatest effect on its condition. To protect the engine from such extreme loads, the best electric saws from well-known manufacturers are equipped with a system soft start which reduces the dose starting current by gradually accelerating the engine.
Attention to safety!
Any electric saw on a tree is a potentially dangerous tool, so when buying, you should limit yourself as much as possible to possible injuries when using it. Choose a model that blocks the movement of the chain in case of accidental activation by throwing the saw or grabbing the tool with one hand.
The most traumatic moment when working with an electric saw is the kickback that occurs when the end of the bar hits a hard surface. At the same time, the tool is thrown back violently and, with the chain moving, could injure the operator. To prevent backlash accidents, modern electric saws (Partner, Bosch, Makita, etc.) are equipped with an inertial brake.
A chain saw equipped with an electric motor is a relatively young type of tool. Before it, the Druzhba and Ural gasoline models dominated the domestic market.
It was not difficult for Soviet engineers to make the electric motor turn the saw chain. Much more difficult was the task of making it light and at the same time powerful enough.
The main working units of the hand-held electric chain saw borrowed from the gasoline one.
It also has a cutting chain, guide bar, tensioner, chain lubrication system and a motor blocking guard.
The process of starting an electric saw is faster and easier than a gasoline one. There is no need for fuel suction and activation of a candle that supplies a spark to the working cylinder. One press of the power button and the tool is ready to work.
The main components of the chain saw
The electric motor transmits torque to the cutting chain through the gearbox and drive sprocket. At the same time, an oil pump operates, supplying lubricant from the reservoir to the tire.
The simple design guarantees reliable operation of the chain saw. For this reason, this type of tool is used great popularity owners of dachas, country cottages and woodworking professionals.
The range of chain saws with electric drive is quite wide. Therefore, before buying, you need to be well versed in them. technical parameters and operating options.
Specifications and features of choice
In order to choose the right electric chain saw, you should pay attention to the following parameters:
- Engine power.
- The location of the power unit.
- Tire length.
- Saw chain speed.
- Type of power supply (mains, battery).
- Tool weight.
Power is a fundamental characteristic. It is selected based on the type of planned work. If the electric saw is waiting for many hours of work with wood, then the power of the electric motor must be at least 2.5 kW.
A tool of 1.5-2.0 kW will cope with pruning the garden and infrequent sawing of firewood. Since we are dealing with an electric motor, when buying, you need to take into account the quality of the power supply to the site. If low voltage in the mains is a common occurrence, then you need to choose a saw with a power margin. Its motor is more tolerant of unstable power conditions.
Depending on the location of the electric motor relative to the saw chain, there are two options: transverse and longitudinal. The first attracts attention with a lower cost, but is optimal only for cross cutting. The advantage of the longitudinal layout is good weight balancing. It is especially important for cutting at an angle and overhead.
The choice of tire length is not difficult, since it is directly dependent on the diameter of the wood being cut. Judging by the reviews of the owners, for most work on the plot, a tire with a length of 30 to 40 cm is enough.
The speed of the saw chain (m/s) is a parameter that affects the performance of the tool. The faster the chain rotates, the more wood can be cut in the same amount of time. Chain speeds for electric saws range from 9 to 17 m/s.
The weight of an electric saw is directly related to its power. For a tool of low and medium power (from 1.0 to 2.0 kW), it is from 3.6 to 4.8 kg.
Professional electric saws (2.5-3.0 kW) weigh up to 6 kg. Well-known manufacturing companies care about the comfort of working with their tool, so they try to minimize its weight as much as possible. Therefore, do not be surprised if you find saws of the same power on sale, the difference in weight of which differs by 1-1.5 kg.
In the characteristics of cordless chain saws, you will not find a power indicator. Instead, the performance of the tool is evidenced by the magnitude of the supply voltage (from 12 to 36 Volts) and the battery capacity (from 2 to 3 Ah).
Additional options
When discussing the question of which electric chain saw is better, you need to pay attention to the presence of useful working options.
All power saws have a chain brake. It is activated by a protective shield located in front of the operating handle. The brake turns off the engine at the moment the “tire toe” comes into contact with a solid object. From such contact, the saw is thrown upwards, the operator involuntarily hits the protective shield with his left hand, activating the motor lock. The response time is a fraction of a second, so the tool does not have time to cause damage to a person.
But protection against overheating with the help of a built-in thermal relay is not found on all electric saws. This is a useful option that prolongs the life of the engine. It will not be superfluous to have a soft starter on the tool. At the time of switching on, it protects the motor windings from overheating and makes work safer.
The larger the capacity of the oil reservoir, the better, as you will be less likely to have to take your eyes off work to fill it up. The volume of lubricant poured into electric saws is from 120 to 200 ml.
All models have a chain tensioner, but the convenience of using it can vary greatly. Therefore, choose a saw that has an external handle and does not require the use of a wrench or screwdriver.
Saw chain tension options
During the cutting process, it is necessary to periodically control the chain tension force. For this reason, the tensioner should be as accessible and convenient as possible.
Vibration is a factor that reduces comfort and productivity. Therefore, be sure to pay attention to whether the saw has shock-absorbing pads on the front handle and rear handle.
Comparison with petrol chain saws
For a correct comparison, you need to take into account the following parameters:
- Autonomy of use.
- Serviceability.
- Reliability.
- Time of continuous work.
- Price.
In terms of autonomy, network chain saws are inferior to gasoline ones. Their area of action is limited by the length of the "carry". In addition, the power cable makes it difficult to work at height and requires constant attention (to eliminate the risk of falling under the chain).
In terms of ease of maintenance, electric saws are superior to gasoline ones. All their service operations are reduced to the infrequent replacement of worn motor brushes, topping up the oil and tightening the chain.
The more complex the tool is, the more likely it is to break. This rule is also true when comparing chain benzo and electric saws. In an electric saw, as the people say, "there is nothing to break." For a gasoline counterpart, performance depends on a number of factors (the quality of the fuel-oil mixture, the cleanliness of the air filter, the condition of the spark plug).
The duration of continuous operation of gasoline saws is longer. The electric motor needs frequent stops for cooling (after 15-20 minutes). Engine internal combustion rest is required no earlier than 40-50 minutes after launch.
Price is an important argument when buying. Other things being equal, a gas tool designed for cutting wood is more expensive than an electric one.
Finally, we note that the electric drive is more environmentally friendly than the gasoline one. When working with a power saw, you do not have to breathe in toxic exhaust fumes.
Features of operation and maintenance
The main condition for a long life and high-quality work of a chain saw is a well-sharpened and stretched chain. If we add to it the requirement for constant lubrication of the saw bar, then the list of operating rules will be complete. Since the chain tightening time coincides with the moment when the saw needs to be turned off to cool down, it does not introduce discomfort to the work.
The best indicator of the sharpness of saw teeth is sawdust. As long as they are large, you can not worry about sharpening. As soon as their size decreases, you need to turn off the tool, remove the chain and take it to sharpening. Working with a blunt chain is not only physically difficult, but also harmful to the motor, which quickly loses its resource.
Regarding the operation of the chain, the craftsmen give this advice: for work, you need to have two saw chains, periodically changing them to evenly wear the drive sprocket. When its teeth work out and the saw chains begin to slip, they acquire a new set.
After installing a new chain, the saw is allowed to run for 2-3 minutes, after which the tension is checked. To do this, the chain is taken with two fingers in the middle and pulled up. If it comes out of the "stream" of the tire by no more than 3-4 mm, then the tension is normal.
Checking chain tension
