Types of electric saws
If you need to cut a variety of materials – plywood, wood, plastic, chipboard, metal pipes and sheets – you should purchase a circular saw. Cutting is done with a rotating saw blade, and there are specific types of blades for each material. There are two variants of models – manual and fixed, attached to the bed.
A sufficiently versatile tool is a reciprocating saw, which is often used for cutting in hard-to-reach places. It is convenient for roofing and installation work. The working element is a file, the length of which varies from 0.1 m to 0.35 m.It produces oscillatory or translational movements.
A smooth, neat, even curly cut can be made with a jigsaw. It works equally well with ceramics, wood, laminate and metal. The file (working blade) of a jigsaw is indispensable if you need to cut a round hole or make a curved cut.
The best saws for summer cottages are recognized as chain aggregates, the main active element of which is a tire with a chain stretched over it. It is easy to use, relatively compact, and does not require fuel mixture preparation. Almost all gardening work can be done with its help: to knock down an old tree, cut off branches and branches, saw a trunk. It is good for carpentry and construction, especially in confined spaces..
When working with a chain saw outdoors, you must follow the safety rules. For example, you cannot use the tool when it rains – a short circuit is possible
That being said, not every chain saw will give you room for creativity. If you are one of those who like to create elements of arrangement with your own hands, perhaps the best purchase would be a jigsaw: https://diz-cafe.com/tech/kak-vybrat-elektricheskij-lobzik.html
Ergonomics of the unit
If the tool is used quite often, when choosing a saw, many pay attention to the location of the engine. 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..
The advantages of an electric tool
For garden and summer cottage work, both an electric saw and its gasoline counterpart are good, but many still choose the first option. Why is he so attractive?
The power tool, indeed, has a whole list of advantages:
- does not require constant material costs for fuel – gasoline;
- easy to use and maintain;
- makes less noise during operation than a chainsaw;
- clean from an environmental point of view – works without exhaust gases;
- allows for cutting indoors;
- works equally well, despite the climatic features (a gasoline analogue has problems with starting in frosty weather).
If the power source becomes out of reach, a cordless chain saw such as the Makita BUC122Z () comes in handy. Battery and charger need to be purchased separately
Chain tension adjustment
In the process of work, it will be necessary to “pull up” the circuit on the bus from time to time, since it begins 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 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 with which you can quickly tighten 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
Is the chain worn out? Then you need to choose a new one. Tips will tell you how to make the right choice: https://diz-cafe.com/tech/cepi-dlya-elektropil.html
More about the chain saw
First, consider the characteristics that you need to pay attention to when buying.
Engine power
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 saws respond more adequately to voltage drops in the electrical network, 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..
saw Husqvarna 321EL has characteristics suitable for gardening and construction work in the country: power – 2000 W, bar length – 40 cm, smooth start, motor protection
How to choose a good saw: what to look at before buying a machine?
Rest in the country can hardly be called passive – either a gazebo must be built, then a bench must be made, then old trees from the garden must be removed by sawing them into neat blanks to create a decor. In addition to the usual hand tools for wood – a plane, chisel, hammer, jigsaw – many owners have more serious equipment, such as a wood saw. With its help, not only the porch – the whole house can be built.
Engine power indicators
The choice of a chain saw for this indicator should be carried out based on the conditions of use of the device. To cut old branches in the garden, it will be enough to choose saws with minimum power indicators.
In the case of regular and long-term use of the tool, say for sawing thick trees, it is worth focusing on more powerful units. In the first case, it will be quite enough to choose a saw with an operating power in the range of 1.5–2 kW.
The power of the tool, which will be used often and will do a large amount of work, should be in the range of 2.5 to 4 kW. In the case of using the device in country houses or in summer cottages, experts advise buying a lower power tool or additionally purchasing a voltage stabilizer in the power grid.
The fact is that the voltage in the electrical network in suburban settlements is extremely unstable and the tool often simply does not have enough incoming voltage for normal operation..
In order to minimize the shortage of voltage, the current increase function is activated in the electric motor. This puts additional stress on the engine, which reduces its overall running time..
Electric Saw Chain Brake
A very essential function capable of protecting the worker. The thing is that when cutting hard woods or other materials, when the rotating chain comes into contact with the material, the tool is often thrown up sharply towards the person who is cutting.
The presence of the chain stop function, which is made in the form of a plastic shield and located near the tool handle, allows an involuntary hand movement at the time of the saw rebound.
This movement will move the safety guard forward and stop the chain momentarily. The chain stops instantly, so the possibility of injury to a person is completely excluded.
Overheat protection. This function is a relay that regulates the temperature of the device. When the maximum load is reached, the relay automatically switches off the engine, thereby preventing its overheating or ignition.
Engine heating can occur for various reasons, but the most common are situations when the chain is seized during operation or when the oil level in the tool reaches a critical level..
Location of the electric motor
Actually, in modern saws there are two options for location, longitudinal and transverse. Cross-motor saws are great for vertical cuts.
It is convenient to use such a saw to cut felled trees or to harvest firewood. The disadvantage of this arrangement is the disturbed balance of the instrument, which causes significant discomfort when holding it in the hands for a long time..
The lateral position of the motor on the chain saw also makes it difficult to cut trees horizontally. The cuts with such a saw are not quite even. But it is worth noting that the price of saws with this engine arrangement is cheaper than models with a longitudinal electric motor..
A chain saw with a motor, which is placed along the body of the device, will help to cut the tree more comfortably. The cost of units with a longitudinal arrangement of the electric motor is higher, but by overpaying you can become the owner of a universal tool.
Thanks to the longitudinal positioning, the chain saw is perfectly balanced and comfortable to hold in your hands. With such a saw, it is efficient to cut at any angle and the process itself will be more comfortable..
Blade length. Depending on the purpose for which the tool is used, the length of the cutting part (tire) also varies..
Small tires with a length of 30 to 40 centimeters are quite suitable for working on personal plots, trimming branches and preparing firewood. If you need to cut on an industrial scale, you will need a longer bar.
How the saw works
The saw works as follows. After connecting the tool to the 220 V electrical network and pressing the power button, the electric motor starts.
The running motor drives the gearbox, which makes the tire rotate on which the metal chain is fixed..
Actually, with the help of a rapidly rotating chain, the sawing is carried out. Saw-mounted oil pump ensures that oil gets into the chain cutting elements.
This process lubricates the chain. This improves the efficiency of the saw and increases its service life..

The most famous foreign firms producing high quality electric tools are:
- Bosch.
- Stihl.
- Foresta.
- Partner.
- Sparky.
Cheaper, but no less reliable analogs of foreign chain saws are domestic models from manufacturers such as Zenit, Interskol and others. the saw is not the tool to save on.
By purchasing cheap counterparts from dubious manufacturers, you can get a low-quality, heavy, noisy or power tool that does not have proper protective devices.
How to choose a good chain saw: the nuances of choice
The saw is indispensable in a country house. Since the manual version of this tool requires considerable effort from its owner, the advent of automatic chain saws was received with enthusiasm..
The source of energy for work can be gasoline or electricity, with the latter option being more popular among non-professionals. Therefore, the question of how to choose the right chain saw is of great importance. But first, you need to figure out what technical elements the saw consists of and what the principle of its operation is based on..
Blocking function
This locking device is found in all modern chain saws. If this button is not present in some electric tool, then such a unit is a low-quality fake.
The ability to lock the saw is an extremely useful function that guarantees safety, eliminates the possibility of accidental and untimely switching on of the tool and the occurrence of accidents.
In order to quickly and efficiently cut wood, you must use a chain saw. This tool is indispensable when it comes to working with wood..
There are many models of domestic and foreign manufacturers on the market. Unlike gasoline counterparts, electric models are more unpretentious in operation, but they are also less mobile and dependent on the presence of a stable voltage..
Choosing a suitable saw model is quite difficult, but guided by the points described above and taking into account the advice of professionals, it will be much easier to make the right choice..

What are the most important saw indicators?
Any electric saw includes the main structural parts: a motor placed under a plastic or metal case, guides, the chain itself and a pump with a reservoir that supplies oil. When the product is turned on, the motor transmits torque to the sprocket using a special bevel gearbox or even through a direct drive. In the most modern models, manufacturers install a centrifugal clutch system. They reliably protect the electric motor and gearbox from damage..
Chain oil is in a container, with the help of a pump it is supplied to the tire, after which it is evenly distributed over all internal elements of the product. Many designs are equipped with a system for adjusting the amount of lubrication. This makes it possible to cut materials with different hardness. The volume of the oil reservoir is on average about 150-200 ml – this amount will be quite enough for full and continuous operation for two hours. It is very important to keep track of the remaining amount. An electric motor running dry will quickly overheat and soon simply fail. There are usually transparent inserts on the tank body so that you can quickly check the remaining amount of oil.
Like any other models of power tools for the home, saws of this type are presented on the market for household and professional designs. The latter have increased power, so they can be used without interruption for much longer. Household products are not designed for continuous continuous operation – approximately every 10-15 minutes they will have to be allowed to rest so that the engine has time to cool down a little.
When choosing, be sure to pay attention to the engine power. This will affect not only the performance of the structure, but also its durability. If the voltage in the network is not stable, professionals recommend giving preference to products equipped with a thermal control system, which will independently turn off the equipment when a certain engine temperature is reached..
Low-profile chains are usually used in the production of saws. Their performance is average, but they practically do not vibrate during work, so your hands will be much less tired. This improves the usability of the tool. Another key parameter is the length of the bar on which the chain is attached. Its length can be in the range from 30 to 45 cm. A 40 cm model is optimal for domestic conditions. Tools with a longer tire length will significantly increase their weight, and they will cost much more. The quality of the cut directly depends on how thick the chain is. It is very important to check that the structure is equipped with a soft start and an inertial brake, the latter being able to stop all the moving parts of the product within just a few seconds. On sale you can find not only chain saws, but also units powered by batteries – these devices are quite convenient, they have excellent autonomy.
