Chain saw: design, principle of operation, rating of the best models

Electric chain saw device and principle of operation

Among the entire range of chain saws, the following can be distinguished: with an electric drive and a gasoline engine. Considering the device of a chain saw, the following main elements can be distinguished in it:

• frame;
• electric motor;
• chain;
• guide rails;
• compartment for the oil pump and the oil itself;
• protective screen, chain brake lever;
• bar fixing screw and chain tension.

The power saw body serves as a panel for buttons that control the inclusion and locking of the tool. There is also a comfortable handle and a protective shield. There are some differences in more modern and improved models, in which you can find a special handle that allows you to control the degree of chain tension.

This tool works as follows: the first action is to start the engine, as a result of which a torque is created that spreads to the gearbox, sprocket and chain, and this leads to the rotation of these elements, thereby starting the sawing process.

Take into account that the chain, equipped with cutting edges, has a greater width compared to a stationary bar, during the operation of the tool there is no risk of jamming in the workpiece material.

In the process of sawing with an electric saw, oil is supplied to the cutting surface of the chain from the container located in the housing, which ensures its lubrication.

Having become familiar with the principle of operation of an electric chain saw, you can proceed to consider the main parameters that need to be considered when choosing this tool.

More about the electric chain saw

First, consider the characteristics that you need to pay attention to when buying. This is one of the most important indicators

For gardening work, a tool with a power of 1000 W to 2100 W is suitable, but it is better to purchase a stronger unit. The fact is that powerful electric saws respond more adequately to voltage drops in the power grid, therefore, they will last longer. For example, the engine of the popular CHAMPION 420 model has a power of 2000 W, that is, with small voltage fluctuations (200-224 V), it will remain operational and will not allow critical overheating.In addition, an indicator of 2000 W or more is a guarantee that in an extreme situation, when a large amount of work needs to be done, the engine will withstand the load.

In addition, an indicator from 2000 W is a guarantee that in an extreme situation, when a large amount of work is required, the engine will withstand the load.

The Husqvarna 321EL electric saw has characteristics suitable for gardening and construction work in the country: power - 2000 W, bar length - 40 cm, soft start, engine protection

If the tool is used quite often, when choosing an electric saw, many pay attention to the location of the motor. It comes in two versions - longitudinal and transverse

Experts believe that it is much easier to work with a saw with the engine along the tire. In addition, longitudinal units have better balancing.

In the process of work, it will be necessary to “pull up” the circuit on the bus from time to time, since it starts to sag from constant voltage. Of course, more convenient are those models where the tensioning system is thought out. For example, the device of the Makita UC4020A household electric saw is such that the chain can be installed and adjusted without disassembly and additional tools. There is a small lever in the body panel that you can use to quickly tension the chain.

STIHL has equipped its products with a quick chain tensioning system. To do this, it is enough to loosen the cover fastening nut and adjust the chain using the wheel

Modern models are equipped with an automatic system that abruptly stops work in the event of a reverse impact. This greatly extends the service life of the equipment. Chain elements are also lubricated automatically. To control the oil level, there is a special window, and you do not need to disassemble the tool for refueling - there is a small hole in the case.

For chain lubrication, the manufacturer recommends using "native" oil, which is usually sold in the same place as chain saws

The choice of tool depends on the purpose, frequency of use and price. A properly selected power saw will be a good helper in various works with wood, and there are usually a lot of them both during construction and during the improvement of a suburban area.

The principle of operation of the electric chain saw

The saw is a useful tool in the household, which is often used when cutting branches in the garden, sawing wood and carpentry.

Compact and easy-to-use tool does not require knowledge and skills in handling a gasoline engine

Initially, hand-held chainsaw models were quite bulky and heavy. Unsurprisingly, the introduction of electric chainsaws to the market has been enthusiastically received by most consumers. In addition to ease of use, a significant advantage of the power tool is that it is environmentally friendly, since it does not emit exhaust gases during operation. This is especially true when cutting materials in confined spaces.

The main structural elements of the electric chain saw are:

• electric motor in the housing;
• guide rails;
• chain;
• oil pump with oil reservoir.

When the unit is turned on, the motor generates a rotary motion, which is transmitted to the sprocket by means of a bevel gear or direct drive. The sprocket placed in the common plane with the chain begins to rotate it, so that the cutting blade easily cuts wood.

Recently, many manufacturers are equipping models with a centrifugal clutch, thereby preventing damage to the electric motor and saw gear during a loop.

Electric models of chain saws are famous for their long service life, which is achieved due to constant lubrication of movable elements during operation.

The chain oil in a special container is pumped by a pump onto the tire, from which it spreads through the chain along the sprockets and the cutting blade. Many models have a lubrication intensity adjustment function that allows you to work with materials of different hardness.

The volume of the container is on average 120-200 ml.This volume is enough for 2 hours of continuous work. The operator's task is to control the oil level in the tank, otherwise, working "dry" the motor will quickly overheat and the tool will fail.

To facilitate the task of controlling the volume of liquid, manufacturers make transparent inserts in the case or provide for a special probe.

Which electric saw to choose for a summer residence

Electric saw for wood

Currently, electric wood saws are presented in various varieties, therefore, they must take into account the level of functionality of the tool used. Each species has certain technical parameters, so you need to clearly understand what it is desirable to opt for.

• A circular (circular) saw is one of the most useful and functional. It is ideal for cutting a variety of materials, including plywood, plastic, metal, chipboard, so its use is not limited to wood processing. The cut is carried out with a rotating disc, and it can be used taking into account the work ahead.
• Reciprocating power saw is also considered to be quite versatile. It is suitable for cutting materials in hard-to-reach places. The working element is a file with a length of 0.1 - 0.35 m. The saw can carry out oscillatory or translational movements.
• The electric jigsaw allows you to create even curved cuts, and it is successfully used for working with a variety of materials. The working blade is a nail file. It is successfully used to create curved cuts, round holes.
• Electric chain saws for wood for summer cottages and houses are also recognized as worthy electric tools. In this case, the main element will be a tire with a tensioned chain. Such a saw will be convenient and compact. The chain saw is ideal for quick and easy gardening, carpentry and construction.

Given the features of the varieties presented, you can understand which saw is desirable to choose for subsequent work.

Evaluation Criteria for Electric Saws

When compiling our rating of electric saws, we were guided by certain criteria that play an important role in the operation of the tool.

Power. For work in the garden or in the country, there is no need for a powerful engine - for simple tasks, a tool with a motor power of up to 2 kW is suitable for you. More powerful chain saws (2.2-2.5 kW) can be used in intensive mode without the threat of overheating of the motor or failure of individual units and parts.

Engine location. Motors on modern electric saws have a transverse or longitudinal arrangement, while with a transverse arrangement, the engine can be located both to the left and to the right of the operator. Longitudinally motorized chain saws are said to be more maneuverable, better balanced and less fatigued to the operator's arms and back. At the same time, with the transverse arrangement, the power of the tool increases due to the direct transmission of power from the motor to the saw headset.

Chain tensioner. Today, manufacturers produce electric saws with two types of chain tensioners: classic (the chain is adjusted using special keys) and toolless. The second type is much more convenient, and the adjustment process itself does not take much time. At the same time, some users prefer the classic type as more reliable.

Smooth start. The presence of the "Soft start" option protects the engine from overloads when the engine is turned on and provides additional operator safety. Not all tools have this feature.

Chain brake. Oddly enough, but not all manufacturers equip their saws with an instant chain stop brake. Meanwhile, it is a very important system that ensures the safety of the operator's work.We advise you not to regret a few dollars and opt for a tool equipped with a chain stop brake.

Manufacturer. Many people wonder whether it is worth overpaying for a branded model. As practice shows, global manufacturers care about the good name of their companies and do not allow themselves to produce low-quality products. Even if you overpay a little when buying products from Bosch, Makita, Stihl or Husqvarna, then you will significantly save on repairs and spare parts. However, there are enough tools on the market from little-known companies that have an ideal value for money: as always, the choice is yours.

Our top ranking is based on surveys of sellers, as well as on the opinions of users from various forums. You can find some comments from the owners of the tools in our review.

Dewalt circular saws

popular with consumers

If we talk about such a parameter as power, then, we note that for most Dewalt circular saws this figure is 3 kW. This allows, when using the tool at idle speed, to make more than 4 thousand revolutions per minute.

The tool of this company has a speed regulator, which can be located not only in the upper part, but also on the side panel.

Almost all models of this brand are equipped with protective elements - spindles. They are distinguished by the high strength of their bases. Also, the saw models of this manufacturer have an anti-vibration system.

If, during the operation of the tool, it became necessary to replace the saw blade, then this can be done without any problems. If we talk about the price for the model of the Dewalt company, then on average it is at the level of 8 thousand rubles.

Characteristics of the Dewalt D 2400 model

On this model, you can easily change the speed thanks to the small regulator with which it is equipped. The manufacturer has provided a controller for the cutting depth. However, cutting wood at an angle using this model is quite difficult.

This electric saw is not suitable for cutting metal. However, it can be used for cutting plastic operations. When performing such a task, there are no big problems.

The tool has a protective spindle, which is very robust and able to withstand heavy loads. As part of the design of this tool, there is a fairly voluminous handle.

7. Weight 10.5 kg.

Even when working with a small electric saw, work clothes are needed, they will ensure safety, which is very important when working with power tools. The special piece is useful not only for cutting wood, but also for other work in the garden

Hacksaw for wood

A hacksaw and bow saw is a hand-held tool for cutting wood. They can be used for garden work. Ideal for cutting thick branches and limbs. The hacksaw does not burden your hands. It is best to choose a model with a hardened, fine-toothed stainless steel blade. Since this hand tool requires a lot of physical effort from the user, it is not suitable for women.

Mechanical saws

To speed up the process of sawing logs, you can use a mechanical tool, for example:

• a chainsaw with an internal combustion engine;
• manual power saw;
• cordless saw.

They require less effort. Also useful for other jobs. Before deciding to purchase, you need to think about the purpose and amount of firewood for cutting. If you have no experience, you should choose a lower power saw. It is easier to use. The choice of the length of the cutting tool depends on the diameter of the tree and its hardness. The more power the saw has, the longer the blade.

Electric saws are easy to use and lighter in weight than other types of power tools for sawing logs. They are designed for mains supply. Their added advantage is that they do not emit exhaust gases. Unfortunately, their range is limited by the length of the cable. The handheld electric circular saw and alligator are not suitable for cutting cylindrical objects, they are successfully used by carpenters when sawing boards and chipboard panels.

When choosing a chainsaw, you should take into account its power, the number of chain revolutions, weight and the presence of a protective device. For lovely ladies, the best choice is a handheld electric wood saw.
